-From Karl (x11vnc's father) on Apr 2, 2003:
-	
-New option -nocursor to not display the vncviewer local cursor if user
-does not want it (also caused some problems with older vncviewers)
-
-New option -mouse to show the position of the X server mouse (i.e. lagged
-from the user's vnc cursor position).  Also: -mouseX will try to show
-the a different cursor (X) when on the root background.
-
-New option -many to wait for more connections rather than exiting when
-the first client(s) disconnect.
-
-New option -flashcmap to try to follow installed colormaps under 8bpp
-indexed color as pointer is moved.
-
-New option -nap to watch for low activity and throttle down the polling
-rate.  Useful on shared machines to keep the load down.
-
-Experimental option -id <windowid> to show just that window and not
-the whole display.  Some remaining bugs and inconvenient behavior...
-(e.g. new toplevels can be unseen)
-
-Fixed bug on multi-headed machines where the screen number was being
-ignored in a number of places.
-
-Fixed bug wrt connect_once mode.  Now just refuses new clients unless
-shared rather than terminating all clients.
-
-Try to follow changing default colormap under 8bpp indexed color
-as color cells are added.
-
-Needed to pick up HAVE_LIBPTHREAD from autoconf.
-
-defined a select() macro for usleep() since usleep is not always thread
-safe.
-
-Catch and exit on errors in the shm setup work (XShmCreateImage, shmget,...)
-and moved the creation and removal work to separate utility functions.
-
-Added signal and X error handlers to try to clean out the shm objects
-before exiting on interrupt, etc.
-
-Improved performance a bit on the memcmp() in scan_display() by checking
-the whole line first.
-
-Added a workaround when threaded where libvncserver may disconnect too
-early if it does not hear from a client (a small heartbeat is sent).
-This may not be needed any longer.
-
-If -desktop has not been prescribed, try to choose a title based on DISPLAY
-and the hostname (and window name under -id).

-x11vnc: a VNC server for real X displays
-                (to FAQ)    (to Downloads)    (to Building)    (to Beta Test)
-  (to Donations) [PayPal] 
-
-   x11vnc allows one to view remotely and interact with real X displays
-   (i.e. a display corresponding to a physical monitor, keyboard, and
-   mouse) with any VNC viewer. In this way it plays the role for Unix/X11
-   that WinVNC plays for Windows.
-
-   It has built-in SSL/TLS encryption and 2048 bit RSA authentication,
-   including VeNCrypt support; UNIX account and password login support;
-   server-side scaling; single port HTTPS/HTTP+VNC; Zeroconf service
-   advertising; and TightVNC and UltraVNC file-transfer. It has also been
-   extended to work with non-X devices: natively on Mac OS X Aqua/Quartz,
-   webcams and TV tuner capture devices, and embedded Linux systems such
-   as Qtopia Core. Full IPv6 support is provided. More features are
-   described here.
-
-   It also provides an encrypted Terminal Services mode (-create, -svc,
-   or -xdmsvc options) based on Unix usernames and Unix passwords where
-   the user does not need to memorize his VNC display/port number.
-   Normally a virtual X session (Xvfb) is created for each user, but it
-   also works with X sessions on physical hardware. See the tsvnc
-   terminal services mode of the SSVNC viewer for one way to take
-   advantage of this mode.
-
-   I wrote x11vnc back in 2002 because x0rfbserver was basically
-   impossible to build on Solaris and had poor performance. The primary
-   x0rfbserver build problems centered around esoteric C++ toolkits.
-   x11vnc is written in plain C and needs only standard libraries and so
-   should work on nearly all Unixes, even very old ones. I also created
-   enhancements to improve the interactive response, added many features,
-   and etc.
-
-   This page including the FAQ contains much information [*]; solutions
-   to many problems; and interesting applications, but nevertheless
-   please feel free to contact me if you have problems or questions (and
-   if I save you time or expense by giving you some of my time, please
-   consider a PayPal Donation.) Do check the FAQ and this page first; I
-   realize the pages are massive, but you can often use your browser's
-   find-in-page search action using a keyword to find the answer to your
-   problem or question.
-
-   SSVNC:  An x11vnc side-project provides an Enhanced TightVNC Viewer
-   package (SSVNC) for Unix, Windows, and Mac OS X with automatic SSL
-   and/or SSH tunnelling support, SSL Certificate creation, Saved
-   connection profiles, Zeroconf, VeNCrypt, and built-in Proxy support.
-   Added features for the TightVNC Unix viewer: NewFBSize, ZRLE encoding,
-   Viewer-side Scaling, cursor alphablending, low color modes, and
-   enhanced popup menu; UltraVNC extensions support for: File Transfer,
-   Text Chat, Single Window, Server Input, and 1/n Scaling extensions,
-   and UltraVNC DSM encryption. The SSVNC bundle could be placed on, say,
-   a USB memory stick for SSL/SSH VNC viewing from nearly any networked
-   computer.
-
-     _________________________________________________________________
-
-    Announcements:
-
-   Important: If you created any permanent SSL certificates (e.g. via
-   "x11vnc -ssl SAVE ...") on a Debian or Ubuntu system from Sept. 2006
-   through May 2008, then those keys are likely extremely weak and can be
-   easily cracked. The certificate files should be deleted and recreated
-   on a non-Debian system or an updated one. See
-   http://www.debian.org/security/2008/dsa-1571 for details. The same
-   applies to SSH keys (not used by x11vnc directly, but many people use
-   SSH tunnels for VNC access.)
-
-   FAQ moved: The huge FAQ has finally been moved to its own page. If you
-   are trying to follow someone's link to an FAQ once on this page it is
-   now a broken link. Try inserting the string "faq.html", e.g.:
-from:   http://www.karlrunge.com/x11vnc/#faq-singleclick
-to:     http://www.karlrunge.com/x11vnc/faq.html#faq-singleclick
-
-   Apologies for the inconvenience, unfortunately it is not possible to
-   automatically redirect to the new page since the '#' anchor is not
-   sent to the webserver.

-
-    Background:
-
-   VNC (Virtual Network Computing) is a very useful network graphics
-   protocol (applications running on one computer but displaying their
-   windows on another) in the spirit of X, however, unlike X, the
-   viewing-end is very simple and maintains no state. It is a remote
-   framebuffer (RFB) protocol.
-
-   Some VNC links:
-     * http://www.realvnc.com
-     * http://www.tightvnc.com
-     * http://www.ultravnc.com/
-     * http://www.testplant.com/products/vine_server/OS_X
-
-   For Unix, the traditional VNC implementation includes a "virtual" X11
-   server Xvnc (usually launched via the vncserver command) that is not
-   associated with a physical display, but provides a "fake" one X11
-   clients (xterm, firefox, etc.) can attach to. A remote user then
-   connects to Xvnc via the VNC client vncviewer from anywhere on the
-   network to view and interact with the whole virtual X11 desktop.
-
-   The VNC protocol is in most cases better suited for remote connections
-   with low bandwidth and high latency than is the X11 protocol because
-   it involves far fewer "roundtrips" (an exception is the cached pixmap
-   data on the viewing-end provided by X.) Also, with no state maintained
-   the viewing-end can crash, be rebooted, or relocated and the
-   applications and desktop continue running. Not so with X11.
-
-   So the standard Xvnc/vncserver program is very useful, I use it for
-   things like:
-     * Desktop conferencing with other users (e.g. code reviews.)
-     * Long running apps/tasks I want to be able to view from many places
-       (e.g. from home and work.)
-     * Motif, GNOME, and similar applications that would yield very poor
-       performance over a high latency link.
-
-   However, sometimes one wants to connect to a real X11 display (i.e.
-   one attached to a physical monitor, keyboard, and mouse: a Workstation
-   or a SunRay session) from far away. Maybe you want to close down an
-   application cleanly rather than using kill, or want to work a bit in
-   an already running application, or would like to help a distant
-   colleague solve a problem with their desktop, or would just like to
-   work out on the deck for a while. This is where x11vnc is useful.
-     _________________________________________________________________
-
-    How to use x11vnc:
-
-   In this basic example let's assume the remote machine with the X
-   display you wish to view is "far-away.east:0" and the workstation you
-   are presently working at is "sitting-here.west".
-
-   Step 0. Download x11vnc (see below) and have it available to run on
-   far-away.east (on some linux distros it is as easy as "apt-get install
-   x11vnc", "emerge x11vnc", etc.) Similarly, have a VNC viewer (e.g.
-   vncviewer) ready to run on sitting-here.west. We recommend TightVNC
-   Viewers (see also our SSVNC viewer.)
-
-   Step 1. By some means log in to far-away.east and get a command shell
-   running there. You can use ssh, or even rlogin, telnet, or any other
-   method to do this. We do this because the x11vnc process needs to be
-   run on the same machine the X server process is running on (otherwise
-   things would be extremely slow.)
-
-   Step 2. In that far-away.east shell (with command prompt "far-away>"
-   in this example) run x11vnc directed at the far-away.east X session
-   display:
-
-  far-away> x11vnc -display :0
-
-   You could have also set the environment variable DISPLAY=:0 instead of
-   using "-display :0". This step attaches x11vnc to the far-away.east:0
-   X display (i.e. no viewer clients yet.)
-
-   Common Gotcha: To get X11 permissions right, you may also need to set
-   the XAUTHORITY environment variable (or use the -auth option) to point
-   to the correct MIT-MAGIC-COOKIE file (e.g. /home/joe/.Xauthority.) If
-   x11vnc does not have the authority to connect to the display it exits
-   immediately. More on how to fix this below.
-
-   If you suspect an X11 permissions problem do this simple test: while
-   sitting at the physical X display open a terminal window
-   (gnome-terminal, xterm, etc.) You should be able to run x11vnc
-   successfully in that terminal without any need for command line
-   options. If that works OK then you know X11 permissions are the only
-   thing preventing it from working when you try to start x11vnc via a
-   remote shell. Then fix this with the tips below.
-
-   Note as of Feb/2007 you can also try the -find option instead of
-   "-display ..." and see if that finds your display and Xauthority. Note
-   as of Dec/2009 the -findauth and "-auth guess" options may be helpful
-   as well.
-   (End of Common Gotcha)
-
-   When x11vnc starts up there will then be much chatter printed out (use
-   "-q" to quiet it), until it finally says something like:
-  .
-  .
-  13/05/2004 14:59:54 Autoprobing selected port 5900
-  13/05/2004 14:59:54 screen setup finished.
-  13/05/2004 14:59:54
-  13/05/2004 14:59:54 The VNC desktop is far-away:0
-  PORT=5900
-
-   which means all is OK, and we are ready for the final step.
-
-   Step 3. At the place where you are sitting (sitting-here.west in this
-   example) you now want to run a VNC viewer program. There are VNC
-   viewers for Unix, Windows, MacOS, Java-enabled web browsers, and even
-   for PDA's like the Palm Pilot and Cell Phones! You can use any of them
-   to connect to x11vnc (see the above VNC links under "Background:" on
-   how to obtain a viewer for your platform or see this FAQ. For Solaris,
-   vncviewer is available in the Companion CD package SFWvnc.)
-
-   In this example we'll use the Unix vncviewer program on sitting-here
-   by typing the following command in a second terminal window:
-
-  sitting-here> vncviewer far-away.east:0
-
-   That should pop up a viewer window on sitting-here.west showing and
-   allowing interaction with the far-away.east:0  X11 desktop. Pretty
-   nifty! When finished, exit the viewer: the remote x11vnc process will
-   shutdown automatically (or you can use the -forever option to have it
-   wait for additional viewer connections.)
-
-   Common Gotcha: Nowadays there will likely be a host-level firewall on
-   the x11vnc side that is blocking remote access to the VNC port (e.g.
-   5900.) You will either have to open up that port (or a range of ports)
-   in your firewall administration tool, or try the SSH tunnelling method
-   below (even still the firewall must allow in the SSH port, 22.)
-
-
-   Shortcut: Of course if you left x11vnc running on far-away.east:0 in a
-   terminal window with the -forever option or as a service, you'd only
-   have to do Step 3 as you moved around. Be sure to use a VNC Password
-   or other measures if you do that.
-
-
-   Super Shortcut: Here is a potentially very easy way to get all of it
-   working.
-     * Have x11vnc (0.9.3 or later) available to run on the remote host
-       (i.e. in $PATH.)
-     * Download and unpack a SSVNC bundle (1.0.19 or later, e.g.
-       ssvnc_no_windows-1.0.28.tar.gz) on the Viewer-side machine.
-     * Start the SSVNC Terminal Services mode GUI: ./ssvnc/bin/tsvnc
-     * Enter your remote username@hostname (e.g. fred@far-away.east) in
-       the "VNC Terminal Server" entry.
-     * Click "Connect".
-
-   That will do an SSH to username@hostname and start up x11vnc and then
-   connect a VNC Viewer through the SSH encrypted tunnel.
-
-   There are a number of things assumed here, first that you are able to
-   SSH into the remote host; i.e. that you have a Unix account there and
-   the SSH server is running. On Unix and MacOS X it is assumed that the
-   ssh client command is available on the local machine (on Windows a
-   plink binary is included in the SSVNC bundle.) Finally, it is assumed
-   that you are already logged into an X session on the remote machine,
-   e.g. your workstation (otherwise, a virtual X server, e.g. Xvfb, will
-   be started for you.)
-
-   In some cases the remote SSH server will not run commands with the
-   same $PATH that you normally have in your shell there. In this case
-   click on Options -> Advanced -> X11VNC Options, and type in the
-   location of the x11vnc binary under "Full Path". (End of Super
-   Shortcut)
-
-
-   Desktop Sharing: The above more or less assumed nobody was sitting at
-   the workstation display "far-away.east:0". This is often the case: a
-   user wants to access her workstation remotely. Another usage pattern
-   has the user sitting at "far-away.east:0" and invites one or more
-   other people to view and interact with his desktop. Perhaps the user
-   gives a demo or presentation this way (using the telephone for vocal
-   communication.) A "Remote Help Desk" mode would be similar: a
-   technician connects remotely to the user's desktop to interactively
-   solve a problem the user is having.
-
-   For these cases it should be obvious how it is done. The above steps
-   will work, but more easily the user sitting at far-away.east:0 simply
-   starts up x11vnc from a terminal window, after which the guests would
-   start their VNC viewers. For this usage mode the "-connect
-   host1,host2" option may be of use to automatically connect to the
-   vncviewers in "-listen" mode on the list of hosts.
-     _________________________________________________________________
-
-    Tunnelling x11vnc via SSH:
-
-   The above example had no security or privacy at all. When logging into
-   remote machines (certainly when going over the internet) it is best to
-   use ssh, or use a VPN (for a VPN, Virtual Private Network, the above
-   example should be pretty safe.)
-
-   For x11vnc one can tunnel the VNC protocol through an encrypted ssh
-   channel. It would look something like running the following commands:
-  sitting-here> ssh -t -L 5900:localhost:5900 far-away.east 'x11vnc -localhost
--display :0'
-
-   (you will likely have to provide passwords/passphrases to login from
-   sitting-here into your far-away.east Unix account; we assume you have
-   a login account on far-away.east and it is running the SSH server)
-
-   And then in another terminal window on sitting-here run the command:
-  sitting-here> vncviewer -encodings "copyrect tight zrle hextile" localhost:0
-
-   Note: The -encodings option is very important: vncviewer will often
-   default to "raw" encoding if it thinks the connection is to the local
-   machine, and so vncviewer gets tricked this way by the ssh
-   redirection. "raw" encoding will be extremely slow over a networked
-   link, so you need to force the issue with -encodings "copyrect tight
-   ...". Nowadays, not all viewers use the -encodings option, try
-   "-PreferredEncoding=ZRLE" (although the newer viewers seem to
-   autodetect well when to use raw or not.)
-
-   Note that "x11vnc -localhost ..." limits incoming vncviewer
-   connections to only those from the same machine. This is very natural
-   for ssh tunnelling (the redirection appears to come from the same
-   machine.) Use of a VNC password is also strongly recommended.
-
-   Note also the -t we used above (force allocate pseudoterminal), it
-   actually seems to improve interactive typing response via VNC!
-
-   You may want to add the -C option to ssh to enable compression. The
-   VNC compression is not perfect, and so this may help a bit. However,
-   over a fast LAN you probably don't want to enable SSH compression
-   because it can slow things down. Try both and see which is faster.
-
-   If your username is different on the remote machine use something
-   like: "fred@far-away.east" in the above ssh command line.
-
-   Some VNC viewers will do the ssh tunnelling for you automatically, the
-   TightVNC Unix vncviewer does this when the "-via far-away.east" option
-   is supplied to it (this requires x11vnc to be already running on
-   far-away.east or having it started by inetd(8).) See the 3rd script
-   example below for more info.
-
-   SSVNC:  You may also want to look at the Enhanced TightVNC Viewer
-   (ssvnc) bundles because they contain scripts and GUIs to automatically
-   set up SSH tunnels (e.g. the GUI, "ssvnc", does it automatically and
-   so does this command: "ssvnc_cmd -ssh user@far-away.east:0") and can
-   even start up x11vnc as well.
-
-   The Terminal Services mode of SSVNC is perhaps the easiest way to use
-   x11vnc. You just need to have x11vnc available in $PATH on the remote
-   side (and can SSH to the host), and then on the viewer-side you type
-   something like:
-  tsvnc fred@far-away.east
-
-   everything else is done automatically for you. Normally this will
-   start a virtual Terminal Services X session (RAM-only), but if you
-   already have a real X session up on the physical hardware it will find
-   that one for you.
-
-   Gateways:  If the machine you SSH into is not the same machine with
-   the X display you wish to view (e.g. your company provides incoming
-   SSH access to a gateway machine), then you need to change the above
-   to, e.g.: "-L 5900:OtherHost:5900":
-  sitting-here> ssh -t -L 5900:OtherHost:5900 gateway.east
-
-   Where gateway.east is the internet hostname (or IP) of the gateway
-   machine (SSH server.) 'OtherHost' might be, e.g., freds-pc or
-   192.168.2.33 (it is OK for these to be private hostnames or private IP
-   addresses, the host in -L is relative to the remote server side.)
-
-   Once logged in, you'll need to do a second login (ssh, rsh, etc.) to
-   the workstation machine 'OtherHost' and then start up x11vnc on it (if
-   it isn't already running.) (The "-connect gateway:59xx" option may be
-   another alternative here with the viewer already in -listen mode.) For
-   an automatic way to use a gateway and have all the network traffic
-   encrypted (including inside the firewall) see Chaining SSH's.
-
-   These gateway access modes also can be done automatically for you via
-   the "Proxy/Gateway" setting in SSVNC (including the Chaining SSH's
-   case, "Double Proxy".)
-
-   Firewalls/Routers:
-
-   A lot of people have inexpensive devices for home or office that act
-   as a Firewall and Router to the machines inside on a private LAN. One
-   can usually configure the Firewall/Router from inside the LAN via a
-   web browser.
-
-   Often having a Firewall/Router sitting between the vncviewer and
-   x11vnc will make it impossible for the viewer to connect to x11vnc.
-
-   One thing that can be done is to redirect a port on the
-   Firewall/Router to, say, the SSH port (22) on an inside machine (how
-   to do this depends on your particular Firewall/Router, often the
-   router config URL is http://192.168.100.1 See www.portforward.com for
-   more info.) This way you reach these computers from anywhere on the
-   Internet and use x11vnc to view X sessions running on them.
-
-   Suppose you configured the Firewall/Router to redirect these ports to
-   two internal machines:
-  Port 12300 -> 192.168.1.3, Port 22 (SSH)
-  Port 12301 -> 192.168.1.4, Port 22 (SSH)
-
-   (where 192.168.1.3 is "jills-pc" and 192.168.1.4 is "freds-pc".) Then
-   the ssh's would look something like:
-  sitting-here> ssh -t -p 12300 -L 5900:localhost:5900 jill@far-away.east 'x11v
-nc -localhost -display :0'
-  sitting-here> ssh -t -p 12301 -L 5900:localhost:5900 fred@far-away.east 'x11v
-nc -localhost -display :0'
-
-   Where far-away.east means the hostname (or IP) that the
-   Router/Firewall is using (for home setups this is usually the IP
-   gotten from your ISP via DHCP, the site http://www.whatismyip.com/ is
-   a convenient way to determine what it is.)
-
-   It is a good idea to add some obscurity to accessing your system via
-   SSH by using some high random port (e.g. 12300 in the above example.)
-   If you can't remember it, or are otherwise not worried about port
-   scanners detecting the presence of your SSH server and there is just
-   one internal PC involved you could map 22:
-  Port 22 -> 192.168.1.3, Port 22 (SSH)
-
-   Again, this SSH gateway access can be done automatically for you via
-   the "Proxy/Gateway" setting in SSVNC. And under the "Remote SSH
-   Command" setting you can enter the x11vnc -localhost -display :0.
-
-   Host-Level-Firewalls: even with the hardware Firewall/Router problem
-   solved via a port redirection, most PC systems have their own Host
-   level "firewalls" enabled to protect users from themselves. I.e. the
-   system itself blocks all incoming connections. So you will need to see
-   what is needed to configure it to allow in the port (e.g. 22) that you
-   desire. E.g. Yast, Firestarter, iptables(1), etc..
-
-   VNC Ports and Firewalls: The above discussion was for configuring the
-   Firewall/Router to let in port 22 (SSH), but the same thing can be
-   done for the default VNC port 5900:
-  Port 5900 -> 192.168.1.3, Port 5900 (VNC)
-  Port 5901 -> 192.168.1.4, Port 5900 (VNC)
-
-   (where 192.168.1.3 is "jills-pc" and 192.168.1.4 is "freds-pc".) This
-   could be used for normal, unencrypted connections and also for SSL
-   encrypted ones.
-
-   The VNC displays to enter in the VNC viewer would be, say,
-   "far-away.east:0" to reach jills-pc and "far-away.east:1" to reach
-   freds-pc. We assume above that x11vnc is using port 5900 (and any
-   Host-Level-firewalls on jills-pc has been configured to let that port
-   in.) Use the "-rfbport" option to tell which port x11vnc should listen
-   on.
-
-   For a home system one likely does not have a hostname and would have
-   to use the IP address, say, "24.56.78.93:0". E.g.:
-  vncviewer 24.56.78.93:0
-
-   You may want to choose a more obscure port on the router side, e.g.
-   5944, to avoid a lot of port scans finding your VNC server. For 5944
-   you would tell the viewer to use:
-  vncviewer 24.56.78.93:44
-
-   The IP address would need to be communicated to the person running the
-   VNC Viewer. The site http://www.whatismyip.com/ can help here.
-
-     _________________________________________________________________
-
-   Scripts to automate ssh tunneling: As discussed below, there may be
-   some problems with port 5900 being available. If that happens, the
-   above port and display numbers may change a bit (e.g. -> 5901 and :1).
-   However, if you "know" port 5900 will be free on the local and remote
-   machines, you can easily automate the above two steps by using the
-   x11vnc option -bg (forks into background after connection to the
-   display is set up) or using the -f option of ssh. Some example scripts
-   are shown below. Feel free to try the ssh -C to enable its compression
-   and see if that speeds things up noticeably.
-     _________________________________________________________________
-
-   #1. A simple example script, assuming no problems with port 5900 being
-   taken on the local or remote sides, looks like:
-#!/bin/sh
-# usage: x11vnc_ssh <host>:<xdisplay>
-#  e.g.: x11vnc_ssh snoopy.peanuts.com:0
-#  (user@host:N also works)
-
-host=`echo $1 | awk -F: '{print $1}'`
-disp=`echo $1 | awk -F: '{print $2}'`
-if [ "x$disp" = "x" ]; then disp=0; fi
-
-cmd="x11vnc -display :$disp -localhost -rfbauth .vnc/passwd"
-enc="copyrect tight zrle hextile zlib corre rre raw"
-
-ssh -f -t -L 5900:localhost:5900 $host "$cmd"
-
-for i in 1 2 3
-do
-        sleep 2
-        if vncviewer -encodings "$enc" :0; then break; fi
-done
-
-   See also rx11vnc.pl below.
-     _________________________________________________________________
-
-   #2. Another method is to start the VNC viewer in listen mode
-   "vncviewer -listen" and have x11vnc initiate a reverse connection
-   using the -connect option:
-#!/bin/sh
-# usage: x11vnc_ssh <host>:<xdisplay>
-#  e.g.: x11vnc_ssh snoopy.peanuts.com:0
-#  (user@host:N also works)
-
-host=`echo $1 | awk -F: '{print $1}'`
-disp=`echo $1 | awk -F: '{print $2}'`
-if [ "x$disp" = "x" ]; then disp=0; fi
-
-cmd="x11vnc -display :$disp -localhost -connect localhost"   # <== note new opt
-ion
-enc="copyrect tight zrle hextile zlib corre rre raw"
-
-vncviewer -encodings "$enc" -listen &
-pid=$!
-ssh -t -R 5500:localhost:5500 $host "$cmd"
-kill $pid
-
-   Note the use of the ssh option "-R" instead of "-L" to set up a remote
-   port redirection.
-     _________________________________________________________________
-
-   #3. A third way is specific to the TightVNC vncviewer special option
-   -via for gateways. The only tricky part is we need to start up x11vnc
-   and give it some time (5 seconds in this example) to start listening
-   for connections (so we cannot use the TightVNC default setting for
-   VNC_VIA_CMD):
-#!/bin/sh
-# usage: x11vnc_ssh <host>:<xdisplay>
-#  e.g.: x11vnc_ssh snoopy.peanuts.com:0
-
-host=`echo $1 | awk -F: '{print $1}'`
-disp=`echo $1 | awk -F: '{print $2}'`
-if [ "x$disp" = "x" ]; then disp=0; fi
-
-VNC_VIA_CMD="ssh -f -t -L %L:%H:%R %G x11vnc -localhost -rfbport 5900 -display
-:$disp; sleep 5"
-export VNC_VIA_CMD
-
-vncviewer -via $host localhost:0      # must be TightVNC vncviewer.
-
-   Of course if you already have the x11vnc running waiting for
-   connections (or have it started out of inetd(8)), you can simply use
-   the TightVNC "vncviewer -via gateway host:port" in its default mode to
-   provide secure ssh tunnelling.
-     _________________________________________________________________
-
-
-
-   VNC password file: Also note in the #1. example script that the option
-   "-rfbauth .vnc/passwd" provides additional protection by requiring a
-   VNC password for every VNC viewer that connects. The vncpasswd or
-   storepasswd programs, or the x11vnc -storepasswd option can be used to
-   create the password file. x11vnc also has the slightly less secure
-   -passwdfile and "-passwd XXXXX" options to specify passwords.
-
-   Very Important: It is up to YOU to tell x11vnc to use password
-   protection (-rfbauth or -passwdfile), it will NOT do it for you
-   automatically or force you to (use -usepw if you want to be forced
-   to.) The same goes for encrypting the channel between the viewer and
-   x11vnc: it is up to you to use ssh, stunnel, -ssl mode, a VPN, etc.
-   (use the Enhanced TightVNC Viewer (SSVNC) GUI if you want to be forced
-   to use SSL or SSH.) For additional safety, also look into the -allow
-   and -localhost options and building x11vnc with tcp_wrappers support
-   to limit host access.
-
-     _________________________________________________________________
-
-    Tunnelling x11vnc via SSL/TLS:
-
-   One can also encrypt the VNC traffic using an SSL/TLS tunnel such as
-   stunnel.mirt.net (also stunnel.org) or using the built-in (Mar/2006)
-   -ssl openssl mode. A SSL-enabled Java applet VNC Viewer is also
-   provided in the x11vnc package (and https can be used to download it.)
-
-   Although not as ubiquitous as ssh, SSL tunnelling still provides a
-   useful alternative. See this FAQ on -ssl and -stunnel modes for
-   details and examples.
-
-   The Enhanced TightVNC Viewer (SSVNC) bundles contain some convenient
-   utilities to automatically set up an SSL tunnel from the viewer-side
-   (i.e. to connect to "x11vnc -ssl ...".) And many other enhancements
-   too.
-     _________________________________________________________________
-
-    Downloading x11vnc:
-
-   x11vnc is a contributed program to the LibVNCServer project at
-   SourceForge.net. I use libvncserver for all of the VNC aspects; I
-   couldn't have done without it. The full source code may be found and
-   downloaded (either file-release tarball or GIT tree) from the above
-   link. As of Sep 2010, the x11vnc-0.9.12.tar.gz source package is
-   released (recommended download). The x11vnc 0.9.12 release notes.
-
-   The x11vnc package is the subset of the libvncserver package needed to
-   build the x11vnc program. Also, you can get a copy of my latest,
-   bleeding edge x11vnc-0.9.13-dev.tar.gz tarball to build the most up to
-   date one.
-
-   Precompiled Binaries/Packages:  See the FAQ below for information
-   about where you might obtain a precompiled x11vnc binary from 3rd
-   parties and some ones I create.
-
-   VNC Viewers:  To obtain VNC viewers for the viewing side (Windows, Mac
-   OS, or Unix) try these links:

-
-
-   More tools: Here is a ssh/rsh wrapper script rx11vnc that attempts to
-   automatically do the above Steps 1-3 for you (provided you have
-   ssh/rsh login permission on the machine x11vnc is to be run on.) The
-   above example would be: "rx11vnc far-away.east:0" typed into a shell
-   on sitting-here.west. Also included is an experimental script
-   rx11vnc.pl that attempts to tunnel the vnc traffic through an ssh port
-   redirection (and does not assume port 5900 is free.) Have a look at
-   them to see what they do and customize as needed:
-     * rx11vnc wrapper script
-     * rx11vnc.pl wrapper script to tunnel traffic thru ssh
-
-     _________________________________________________________________
-
-    Building x11vnc:
-
-   Make sure you have all the needed build/compile/development packages
-   installed (e.g. Linux distributions foolishly don't install them by
-   default.) See this build FAQ for more details.
-
-   If your OS has libjpeg.so and libz.so in standard locations you can
-   build as follows (example given for the 0.9.12 release of x11vnc:
-   replace with the version you downloaded):
-(un-tar the x11vnc+libvncserver tarball)
-# gzip -dc x11vnc-0.9.12.tar.gz | tar -xvf -
-
-(cd to the source directory)
-# cd x11vnc-0.9.12
-
-(run configure and then run make)
-# ./configure
-# make
-
-(if all went OK, copy x11vnc to the desired destination, e.g. $HOME/bin)
-# cp ./x11vnc/x11vnc $HOME/bin
-
-   Or do make install, it will probably install to /usr/local/bin (run
-   ./configure --help for information on customizing your configuration,
-   e.g. --prefix=/my/place.) You can now run it via typing "x11vnc",
-   "x11vnc -help | more", "x11vnc -forever -shared -display :0", etc.
-
-
-   Note: Currently gcc is recommended to build libvncserver. In some
-   cases it will build with non-gcc compilers, but the resulting binary
-   sometimes fails to run properly. For Solaris pre-built gcc binaries
-   are at http://www.sunfreeware.com/. Some Solaris pre-built x11vnc
-   binaries are here.
-
-   However, one user reports it does work fine when built with Sun Studio
-   10, so YMMV. In fact, here is a little build script to do this on
-   Solaris 10:
-#!/bin/sh
-PATH=/usr/ccs/bin:/opt/SUNWspro/bin:$PATH; export PATH
-
-CC='cc' \
-CFLAGS='-xO4' \
-LDFLAGS='-L/usr/sfw/lib -L/usr/X11/lib -R/usr/sfw/lib -R/usr/X11/lib' \
-CPPFLAGS='-I /usr/sfw/include -I/usr/X11/include' \
-./configure
-
-MAKE="make -e"
-AM_CFLAGS=""
-export MAKE AM_CFLAGS
-$MAKE
-
-   In general you can use the "make -e" trick if you don't like
-   libvncserver's choice of AM_CFLAGS. See the build scripts below for
-   more ideas. Scripts similar to the above have been shown to work with
-   vendor C compilers on HP-UX (ccom: HP92453-01) and Tru64 (Compaq C
-   V6.5-011.)
-
-   You can find information on Misc. Build problems here.
-
-     _________________________________________________________________
-
-   Building on Solaris, FreeBSD, etc:   Depending on your version of
-   Solaris or other Unix OS the jpeg and/or zlib libraries may be in
-   non-standard places (e.g. /usr/local, /usr/sfw, /opt/sfw, etc.)
-
-   Note: If configure cannot find these two libraries then TightVNC and
-   ZRLE encoding support will be disabled, and you don't want that!!! The
-   TightVNC encoding gives very good compression and performance, it even
-   makes a noticeable difference over a fast LAN.
-
-
-   Shortcuts: On Solaris 10 you can pick up almost everything just by
-   insuring that your PATH has /usr/sfw/bin (for gcc) and /usr/ccs/bin
-   (for other build tools), e.g.:
-  env PATH=/usr/sfw/bin:/usr/ccs/bin:$PATH sh -c './configure; make'
-
-   (The only thing this misses is /usr/X11/lib/libXrandr.so.2, which is
-   for the little used -xrandr option, see the script below to pick it up
-   as well.)
-
-
-   libjpeg is included in Solaris 9 and later (/usr/sfw/include and
-   /usr/sfw/lib), and zlib in Solaris 8 and later (/usr/include and
-   /usr/lib.) So on Solaris 9 you can pick up everything with something
-   like this:
-  env PATH=/usr/local/bin:/usr/ccs/bin:$PATH sh -c './configure --with-jpeg=/us
-r/sfw; make'
-
-   assuming your gcc is in /usr/local/bin and x11vnc 0.7.1 or later.
-   These are getting pretty long, see those assignments split up in the
-   build script below.
-
-
-   If your system does not have these libraries at all you can get the
-   source for the libraries to build them: libjpeg is available at
-   ftp://ftp.uu.net/graphics/jpeg/ and zlib at http://www.gzip.org/zlib/.
-   See also http://www.sunfreeware.com/ for Solaris binary packages of
-   these libraries as well as for gcc. Normally they will install into
-   /usr/local but you can install them anywhere with the
-   --prefix=/path/to/anywhere, etc.
-
-
-   Here is a build script that indicates one way to pass the library
-   locations information to the libvncserver configuration via the
-   CPPFLAGS and LDFLAGS environment variables.
----8<---8<---8<---8<---8<---8<---8<---8<---8<---8<---8<---8<---8<---8<---8<---8
-<---
-#!/bin/sh
-
-# Build script for Solaris, etc, with gcc, libjpeg and libz in
-# non-standard locations.
-
-# set to get your gcc, etc:
-#
-PATH=/path/to/gcc/bin:/usr/ccs/bin:/usr/sfw/bin:$PATH
-
-JPEG=/path/to/jpeg      # set to maybe "/usr/local", "/usr/sfw", or "/opt/sfw"
-ZLIB=/path/to/zlib      # set to maybe "/usr/local", "/usr/sfw", or "/opt/sfw"
-
-# Below we assume headers in $JPEG/include and $ZLIB/include and the
-# shared libraries are in $JPEG/lib and $ZLIB/lib.  If your situation
-# is different change the locations in the two lines below.
-#
-CPPFLAGS="-I $JPEG/include -I $ZLIB/include"
-LDFLAGS="-L$JPEG/lib -R $JPEG/lib -L$ZLIB/lib -R $ZLIB/lib"
-
-# These two lines may not be needed on more recent Solaris releases:
-#
-CPPFLAGS="$CPPFLAGS -I /usr/openwin/include"
-LDFLAGS="$LDFLAGS -L/usr/openwin/lib -R /usr/openwin/lib"
-
-# These are for libXrandr.so on Solaris 10:
-#
-CPPFLAGS="$CPPFLAGS -I /usr/X11/include"
-LDFLAGS="$LDFLAGS -L/usr/X11/lib -R /usr/X11/lib"
-
-# Everything needs to built with _REENTRANT for thread safe errno:
-#
-CPPFLAGS="$CPPFLAGS -D_REENTRANT"
-
-export PATH CPPFLAGS LDFLAGS
-
-./configure
-make
-
-ls -l ./x11vnc/x11vnc
-
----8<---8<---8<---8<---8<---8<---8<---8<---8<---8<---8<---8<---8<---8<---8<---8
-<---
-
-   Then do make install or copy the x11vnc binary to your desired
-   destination.
-
-   BTW, To run a shell script, just cut-and-paste the above into a file,
-   say "myscript", then modify the "/path/to/..." items to correspond to
-   your system/environment, and then type: "sh myscript" to run it.
-
-   Note that on Solaris make is /usr/ccs/bin/make, so that is why the
-   above puts /usr/ccs/bin in PATH. Other important build utilities are
-   there too: ld, ar, etc. Also, it is probably a bad idea to have
-   /usr/ucb in your PATH while building.
-
-   Starting with the 0.7.1 x11vnc release the "configure --with-jpeg=DIR
-   --with-zlib=DIR" options are handy if you want to avoid making a
-   script.
-
-   If you need to link OpenSSL libssl.a on Solaris see this method.
-
-   If you need to build on Solaris 2.5.1 or earlier or other older Unix
-   OS's, see this workaround FAQ.
-
-
-   Building on FreeBSD, OpenBSD, ...:   The jpeg libraries seem to be in
-   /usr/local or /usr/pkg on these OS's. You won't need the openwin stuff
-   in the above script (but you may need /usr/X11R6/....) Also starting
-   with the 0.7.1 x11vnc release, this usually works:
-  ./configure --with-jpeg=/usr/local
-  make
-
-
-   Building on HP-UX:   For jpeg and zlib you will need to do the same
-   sort of thing as described above for Solaris. You set CPPFLAGS and
-   LDFLAGS to find them (see below for an example.) You do not need to do
-   any of the above /usr/openwin stuff. Also, HP-UX does not seem to
-   support -R, so get rid of the -R items in LDFLAGS. Because of this, at
-   runtime you may need to set LD_LIBRARY_PATH or SHLIB_PATH to indicate
-   the directory paths so the libraries can be found. It is a good idea
-   to have static archives, e.g. libz.a and libjpeg.a for the nonstandard
-   libraries so that they get bolted into the x11vnc binary (and so won't
-   get "lost".)
-
-   Here is what we recently did to build x11vnc 0.7.2 on HP-UX 11.11
-./configure --with-jpeg=$HOME/hpux/jpeg --with-zlib=$HOME/hpux/zlib
-make
-
-   Where we had static archives (libjpeg.a, libz.a) only and header files
-   in the $HOME/hpux/... directories as discussed for the build script.
-
-   On HP-UX 11.23 and 11.31 we have had problems compiling with gcc.
-   "/usr/include/rpc/auth.h:87: error: field 'syncaddr' has incomplete
-   type". As a workaround for x11vnc 0.9.4 and later set your CPPFLAGS to
-   include:
-  CPPFLAGS="-DIGNORE_GETSPNAM"
-  export CPPFLAGS
-
-   This disables a very rare usage mode for -unixpw_nis by not trying
-   getspnam(3).
-
-   Using HP-UX's C compiler on 11.23 and 11.31 we have some severe
-   compiler errors that have not been worked around yet. If you need to
-   do this, contact me and I will give you a drastic recipe that will
-   produce a working binary.
-
-
-   Building on AIX:   AIX: one user had to add the "X11.adt" package to
-   AIX 4.3.3 and 5.2 to get build header files like XShm.h, etc. You may
-   also want to make sure that /usr/lpp/X11/include, etc is being picked
-   up by the configure and make.
-
-   For a recent build on AIX 5.3 we needed to add these CFLAGS to be able
-   to build with gcc:
-  env CFLAGS='-maix64 -Xlinker -bbigtoc' ./configure ...
-
-   we also built our own libjpeg and libz using -maix64.
-
-   BTW, one way to run an Xvfb-like virtual X server for testing on AIX
-   is something like "/usr/bin/X11/X -force -vfb -ac :1".
-
-
-   Building on Mac OS X:   There is now native Mac OS X support for
-   x11vnc by using the raw framebuffer feature. This mode does not use or
-   need X11 at all. To build you may need to disable X11:
-./configure --without-x ...
-make
-
-   However, if your system has the Mac OS X build package for X11 apps
-   you will not need to supply the "--without-x" option (in this case the
-   resulting x11vnc would be able to export both the native Mac OS X
-   display and windows displayed in the XDarwin X server.) Be sure to
-   include the ./configure option to find libjpeg on your system.
-
-
-   OpenSSL:   Starting with version 0.8.3 x11vnc can now be built with
-   SSL/TLS support. For this to be enabled the libssl.so library needs to
-   be available at build time. So you may need to have additional
-   CPPFLAGS and LDFLAGS items if your libssl.so is in a non-standard
-   place. As of x11vnc 0.9.4 there is also the --with-ssl=DIR configure
-   option.
-
-   On Solaris using static archives libssl.a and libcrypto.a instead of
-   .so shared libraries (e.g. from www.sunfreeware.com), we found we
-   needed to also set LDFLAGS as follows to get the configure to work:
-env LDFLAGS='-lsocket -ldl' ./configure --with-ssl=/path/to/openssl ...
-make
-
-     _________________________________________________________________
-
-    Beta Testing:
-
-   I don't have any formal beta-testers for the releases of x11vnc, so
-   I'd appreciate any additional testing very much.
-
-   Thanks to those who suggested features and helped beta test x11vnc
-   0.9.12 released in Sep 2010!
-
-   Please help test and debug the 0.9.13 version for release sometime in
-   Winter 2010.
-
-   The version 0.9.13 beta tarball is kept here:
-   x11vnc-0.9.13-dev.tar.gz
-
-   There are also some Linux, Solaris, Mac OS X, and other OS test
-   binaries here. Please kick the tires and report bugs, performance
-   regressions, undesired behavior, etc. to me.
-
-   To aid testing of the built-in SSL/TLS support for x11vnc, a number of
-   VNC Viewer packages for Unix, Mac OS X, and Windows have been created
-   that provide SSL Support for the TightVNC Viewer (this is done by
-   wrapper scripts and a GUI that starts STUNNEL.) It should be pretty
-   convenient for automatic SSL and SSH connections. It is described in
-   detail at and can be downloaded from the Enhanced TightVNC Viewer
-   (SSVNC) page. The SSVNC Unix viewer also supports x11vnc's symmetric
-   key encryption ciphers (see the 'UltraVNC DSM Encryption Plugin'
-   settings panel.)
-
-
-   Here are some features that will appear in the 0.9.13 release:
-     * Improved support for non-X11 touchscreen devices (e.g. handheld or
-       cell phone) via Linux uinput input injection. Additional tuning
-       parameters are added. TSLIB touchscreen calibration is supported.
-       Tested on Qtmoko Neo Freerunner. A tool, misc/uinput.pl, is
-       provided to diagnose uinput behavior on new devices. The env.
-       vars. X11VNC_UINPUT_BUS and X11VNC_UINPUT_VERSION are available if
-       leaving them unset does not work.
-     * The Linux uinput non-X11 input injection can now be bypassed:
-       events can be directly written to the /dev/input/event devices
-       specified by the user (direct_abs=..., etc.) A -pipeinput input
-       injection helper script, misc/qt_tslib_inject.pl is provided as a
-       tweakable non-builtin direct input injection method.
-     * The list of new uinput parameters for the above two features is:
-       pressure, tslib_cal, touch_always, dragskip, btn_touch;
-       direct_rel, direct_abs, direct_btn, direct_key.
-     * The MacOSX native server can now use OpenGL for the screen
-       capture. In nearly all cases this is faster than the raw
-       framebuffer capture method. There are build and run time flags,
-       X11VNC_MACOSX_NO_DEPRECATED, etc. to disable use of deprecated
-       input injection and screen access interfaces. Cursor shape now
-       works for 64bit binaries.
-     * The included SSL enabled Java VNC Viewers now handle Mouse Wheel
-       events.
-     * miscellaneous new features and changes:
-     * In -reflect mode, the libvncclient connection can now have the
-       pixel format modified via the environment variables
-       X11VNC_REFLECT_bitsPerSample, X11VNC_REFLECT_samplesPerPixel, and
-       X11VNC_REFLECT_bytesPerPixel
-     * In -create mode the following environment variables are added to
-       fine tune the behavior: FIND_DISPLAY_NO_LSOF: do not use lsof(1)
-       to try to determine the Linux VT, FIND_DISPLAY_NO_VT_FIND: do not
-       try to determine the Linux VT at all, X11VNC_CREATE_LC_ALL_C_OK:
-       do not bother undoing the setting LC_ALL=C that the create_display
-       script sets. The performance of the -create script has been
-       improved for large installations (100's of user sessions on one
-       machine.)
-     * In -unixpw mode, one can now Tab from login: to Password.
-     * An environment variable, X11VNC_SB_FACTOR, allows one to scale the
-       -sb screenblank sleep time from the default 2 secs.
-     * An experimental option -unixsock is available for testing. Note,
-       however, that it requires a manual change to
-       libvncserver/rfbserver.c for it to work.
-     * Documented that -grabkbd is no longer working with some/most
-       window managers (it can prevent resizing and menu posting.)
-
-
-   Here are some features that appeared in the 0.9.12 release (Sep/2010):
-     * One can now specify the maximum number of displays that can be
-       created in -create mode via the env. var.
-       X11VNC_CREATE_MAX_DISPLAYS
-     * The X11VNC_NO_LIMIT_SHM env. var. is added to skip any automatic
-       shared memory reduction.
-     * The kdm display manager is now detected when trying not to get
-       killed by the display manager.
-     * A compile time bug is fixed so that configuring using
-       --with-system-libvncserver pointing to LibVNCServer 0.9.7 works
-       again. A bug from forced use of Xdefs.h is worked around.
-
-
-   Here are some features that appeared in the 0.9.11 release (Aug/2010):
-     * The source tree is synchronized with the most recent libvncclient
-       (this only affects -reflect mode.) Build is fixed for
-       incompatibilities when using an external LibVNCServer (e.g.
-       ./configure --with-system-libvncserver...) Please help test these
-       build and runtime aspects and report back what you find, thanks.
-     * The SSL enabled Java VNC Viewer Makefile has been modified so that
-       the jar files that are built are compatible back to Java 1.4.
-     * In -create/-unixpw mode, the env. var. FD_USERPREFS may be set to
-       a filename in the user's home directory that includes default
-       username:options values (so the options do not need to be typed
-       every time at the login prompt.)
-     * In -reflect mode cursor position updates are now handled
-       correctly.
-
-
-   Here are some features that appeared in the 0.9.10 release (May/2010):
-     * The included SSL enabled Java applet viewer now supports Chained
-       SSL Certificates. The debugCerts=yes applet parameter aids
-       troubleshooting certificate validation. The x11vnc -ssl mode has
-       always supported chained SSL certificates (simply put the
-       intermediate certificates, in order, after the server certificate
-       in the pem file.)
-     * A demo CGI script desktop.cgi shows how to create an SSL
-       encrypted, multi-user x11vnc web login desktop service. The script
-       requires x11vnc version 0.9.10. The user logs into a secure web
-       site and gets his/her own virtual desktop (Xvfb.) x11vnc's SSL
-       enabled Java Viewer Applet is launched by the web browser for
-       secure viewing (and so no software needs to be installed on the
-       viewer-side.) One can use the desktop.cgi script for ideas to
-       create their own fancier or customized web login desktop service
-       (e.g. user-creation, PHP, SQL, specialized desktop application,
-       etc.) More info here. There is also an optional 'port redirection'
-       mode that allows redirection to other SSL enabled VNC servers
-       running inside the firewall.
-     * Built-in support for IPv6 (128 bit internet addresses) is now
-       provided. See the -6 and -connect options for details.
-       Additionally, in case there are still problems with built-in IPv6
-       support, a transitional tool is provided in inet6to4 that allows
-       x11vnc (or any other IPv4 application) to receive connections over
-       IPv6.
-     * The Xdummy wrapper script for Xorg's dummy driver is updated and
-       no longer requires being run as root. New service options are
-       provided to select Xdummy over Xvfb as the virtual X server to be
-       created.
-     * The "%" unix password verification tricks for the -unixpw option
-       are now documented. They have also been extended to run a command
-       as the user if one sets the environment variable UNIXPW_CMD. The
-       desktop.cgi demo script takes advantage of this new feature.
-     * A bug has been fixed that would prevent the Java applet viewer
-       from being downloaded successfully in single-port HTTPS/VNC inetd
-       mode. The env. var. X11VNC_HTTPS_DOWNLOAD_WAIT_TIME can be used to
-       adjust for how many seconds a -inetd or -https httpd download is
-       waited for (default 15 seconds.) The applet will now autodetect
-       x11vnc and use GET=1 for faster connecting. Many other
-       improvements and fixes.
-     * The TightVNC security type (TightVNC features enabler) now works
-       for RFB version 3.8.
-     * The X property X11VNC_TRAP_XRANDR can be set on a desktop to force
-       x11vnc to use the -xrandr screen size change trapping code.
-     * New remote control query options: pointer_x, pointer_y,
-       pointer_same, pointer_root, and pointer_mask. A demo script using
-       them misc/panner.pl is provided.
-     * The -sslScripts option prints out the SSL certificate management
-       scripts.
-
-
-   Here are some features that appeared in the 0.9.9 release (Dec/2009):
-     * The -unixpw_system_greeter option, when used in combined unixpw
-       and XDMCP FINDCREATEDISPLAY mode (for example: -xdmsvc), enables
-       the user to press Escape to jump directly to the XDM/GDM/KDM login
-       greeter screen. This way the user avoids entering his unix
-       password twice at X session creation time. Also, the unixpw login
-       panel now has a short help displayed if the user presses 'F1'.
-     * x11vnc now tries to be a little bit more aggressive in keeping up
-       with VNC client's framebuffer update requests. Some broken VNC
-       clients like Eggplant and JollysFastVNC continuously spray these
-       requests at VNC servers (regardless of whether they have received
-       any updates or not.) Under some circumstances this could lead to
-       x11vnc falling behind. The -extra_fbur option allows one to fine
-       tune the setting. Additionally, one may also dial down delays:
-       e.g. "-defer 5" and "-wait 5" (or to 1 or even 0) or -nonap or
-       -allinput to keep up with these VNC clients at the expense of
-       increased system load.
-     * Heuristics are applied to try to determine if the X display is
-       currently in a Display Manager Greeter Login panel (e.g. GDM) If
-       so, x11vnc's creation of any windows and use of XFIXES are
-       delayed. This is to try to avoid x11vnc being killed after the
-       user logs in if the GDM KillInitClients=true is in effect. So one
-       does not need to set KillInitClients=false. Note that in recent
-       GDM the KillInitClients option has been removed. Also delayed is
-       the use of the XFIXES cursor fetching functionality; this avoids
-       an Xorg bug that causes Xorg to crash right after the user logs
-       in.
-     * A new option -findauth runs the FINDDISPLAY script that applies
-       heuristics that try to determine the XAUTHORITY file. The use of
-       '-auth guess' will use the XAUTHORITY that -findauth reveals. This
-       can be handy in with the lastest GDM where the ability to store
-       cookies in ~/.Xauthority has been removed. If x11vnc is running as
-       root (e.g. inetd) and you add -env FD_XDM=1 to the above -findauth
-       or -auth guess command lines, it will find the correct XAUTHORITY
-       for the given display (this works for XDM/GDM/KDM if the login
-       greeter panel is up or if someone has already logged into an X
-       session.)
-     * The FINDDISPLAY and FINDCREATEDISPLAY modes (i.e. "-display
-       WAIT:cmd=...", -find, -create) now work correctly for the
-       user-supplied login program scheme "-unixpw_cmd ...", as long as
-       the login program supports running commands specified in the
-       environment variable "RFB_UNIXPW_CMD_RUN" as the logged-in user.
-       The mode "-unixpw_nis ..." has also been made more consistent.
-     * The -stunnel option (like -ssl but uses stunnel as an external
-       helper program) now works with the -ssl "SAVE" and "TMP" special
-       certificate names. The -sslverify and -sslCRL options now work
-       correctly in -stunnel mode. Single port HTTPS connections are also
-       supported for this mode.
-     * There is an experimental Application Sharing mode that improves
-       upon the -id/-sid single window sharing: -appshare (run "x11vnc
-       -appshare -help" for more info.) It is still very primitive and
-       approximate, but at least it displays multiple top-level windows.
-     * The remote control command -R can be used to instruct x11vnc to
-       resend its most recent copy of the Clipboard, Primary, or
-       Cutbuffer selections: "x11vnc -R resend_clipboard", "x11vnc -R
-       resend_primary", and "x11vnc -R resend_cutbuffer".
-     * The fonts in the GUI (-gui) can now by set via environment
-       variables, e.g. -env X11VNC_FONT_BOLD='Helvetica -16 bold' and
-       -env X11VNC_FONT_FIXED='Courier -14'.
-     * The XDAMAGE mechanism is now automatically disabled for a period
-       of time if a game or screensaver generates too many XDAMAGE
-       rectangles per second. This avoids the X11 event queue from
-       soaking up too much memory.
-     * There is an experimental workaround: "-env X11VNC_WATCH_DX_DY=1"
-       that tries to avoid problems with poorly constructed menu themes
-       that place the initial position of the mouse cursor inside a menu
-       item's active zone. More information can be found here.
-
-
-   Here are some features that appeared in the 0.9.8 release (Jul/2009):
-     * Stability improvements to -threads mode. Running x11vnc this way
-       is more reliable now. Threaded operation sometimes gives better
-       interactive response and faster updates: try it out. The threaded
-       mode now supports multiple VNC viewers using the same VNC
-       encoding. The threaded mode can also yield a performance
-       enhancement in the many client case (e.g. class-room broadcast.)
-       We have tested with 30 to 50 simultaneous clients. See also
-       -reflect.
-       For simultaneous clients: the ZRLE encoding is thread safe on all
-       platforms, and the Tight and Zlib encodings are currently only
-       thread safe on Linux where thread local storage, __thread, is
-       used. If your non-Linux system and compiler support __thread one
-       can supply -DTLS=__thread to enable it. When there is only one
-       connected client, all encodings are safe on all platforms. Note
-       that some features (e.g. scroll detection and -ncache) may be
-       disabled or run with reduced functionality in -threads mode.
-     * Automatically tries to work around an Xorg server and GNOME bug
-       involving infinitely repeating keys when turning off key
-       repeating. Use -repeat if the automatic workaround fails.
-     * Improved reliability of the Single Port SSL VNC and HTTPS java
-       viewer applet delivery mechanism.
-     * The -clip mode works under -rawfb.
-
-
-   Here are some features that appeared in the 0.9.7 release (Mar/2009):
-     * Support for polling Linux Virtual Terminals (also called virtual
-       consoles) directly instead of using /dev/fb. The option to use is,
-       for example, "-rawfb vt2" for Virtual Terminal 2, etc. In this
-       case the special file /dev/vcsa2 is used to retrieve vt2's current
-       text. Text and colors are shown, but no graphics.
-     * Support for less than 8 bits per pixel framebuffers (e.g. 4 or 1
-       bpp) in the -rawfb mode.
-     * The SSL enabled UltraVNC Java viewer applet now has a [Home] entry
-       in the "drives" drop down menu. This menu can be configured with
-       the ftpDropDown applet parameter. All of the applet parameters are
-       documented in classes/ssl/README.
-     * Experimental support for VirtualGL's TurboVNC (an enhanced
-       TightVNC for fast LAN high framerate usage.)
-     * The CUPS Terminal Services helper mode has been improved.
-     * Improvements to the -ncache_cr that allows smooth opaque window
-       motions using the 'copyrect' encoding when using -ncache mode.
-     * The -rmflag option enables a way to indicate to other processes
-       x11vnc has exited.
-     * Reverse connections using anonymous Diffie Hellman SSL encryption
-       now work.
-
-
-   Here are some features that appeared in the 0.9.6 release (Dec/2008):
-     * Support for VeNCrypt SSL/TLS encrypted connections. It is enabled
-       by default in the -ssl mode. VNC Viewers like vinagre,
-       gvncviewer/gtk-vnc, the vencrypt package, SSVNC, and others
-       support this encryption mode. It can also be used with the -unixpw
-       option to enable Unix username and password authentication
-       (VeNCrypt's "*Plain" modes.) A similar but older VNC security type
-       "ANONTLS" (used by vino) is supported as well. See the -vencrypt
-       and -anontls options for additional control. The difference
-       between x11vnc's normal -ssl mode and VeNCrypt is that the former
-       wraps the entire VNC connection in SSL (like HTTPS does for HTTP,
-       i.e. "vncs://") while VeNCrypt switches on the SSL/TLS at a
-       certain point during the VNC handshake. Use -sslonly to disable
-       both VeNCrypt and ANONTLS (vino.)
-     * The "-ssl ANON" option enables Anonymous Diffie-Hellman (ADH) key
-       exchange for x11vnc's normal SSL/TLS operation. Note that
-       Anonymous Diffie-Hellman uses encryption for privacy, but provides
-       no authentication and so is susceptible to Man-In-The-Middle
-       attacks (and so we do not recommend it: we prefer you use "-ssl
-       SAVE", etc. and have the VNC viewer verify the cert.) The ANONTLS
-       mode (vino) only supports ADH. VeNCrypt mode supports both ADH and
-       regular X509 SSL certificates modes. For these ADH is enabled by
-       default. See -vencrypt and -anontls for how to disable ADH.
-     * For x11vnc's SSL/TLS modes, one can now specify a Certificate
-       Revocation List (CRL) with the -sslCRL option. This will only be
-       useful for wide deployments: say a company-wide x11vnc SSL access
-       deployment using a central Certificate Authority (CA) via
-       -sslGenCA and -sslGenCert. This way if a user has his laptop lost
-       or stolen, you only have to revoke his key instead of creating a
-       new Certificate Authority and redeploying new keys to all users.
-     * The default SSL/TLS mode, "-ssl" (no pem file parameter supplied),
-       is now the same as "-ssl SAVE" and will save the generated
-       self-signed cert in "~/.vnc/certs/server.pem". Previously "-ssl"
-       would create a temporary self-signed cert that was discarded when
-       x11vnc exited. The reason for the change is to at least give the
-       chance for the VNC Viewer side (e.g. SSVNC) to remember the cert
-       to authenticate subsequent connections to the same x11vnc server.
-       Use "-ssl TMP" to regain the previous behavior. Use "-ssl
-       SAVE_NOPROMPT" to avoid being prompted about using passphrase when
-       the certificate is created.
-     * The option -http_oneport enables single-port HTTP connections via
-       the Java VNC Viewer. So, for example, the web browser URL
-       "http://myhost.org:5900" works the same as
-       "http://myhost.org:5800", but with the convenience of only
-       involving one port instead of two. This works for both unencrypted
-       connections and for SSH tunnels (see -httpsredir if the tunnel
-       port differs.) Note that HTTPS single-port operation in -ssl SSL
-       encrypted mode has been available since x11vnc version 0.8.3.
-     * For the -avahi/-zeroconf Service Advertizing mode, if x11vnc was
-       not compiled with the avahi-client library, then an external
-       helper program, either avahi-publish(1) (on Unix) or dns-sd(1) (on
-       Mac OS X), is used instead.
-     * The "-rfbport PROMPT" option will prompt the user via the GUI to
-       select the VNC port (e.g. 5901) to listen on, and a few other
-       basic settings. This enables a handy GUI mode for naive users:
-   x11vnc -gui tray=setpass -rfbport PROMPT -logfile $HOME/.x11vnc.log.%VNCDISP
-LAY
-       suitable for putting in a launcher or menu, e.g. x11vnc.desktop.
-       The -logfile expansion is new too. In the GUI, the tray=setpass
-       Properties panel has been improved.
-     * The -solid solid background color option now works for the Mac OS
-       X console.
-     * The -reopen option instructs x11vnc to try to reopen the X display
-       if it is prematurely closed by, say, the display manager (e.g.
-       GDM.)
-
-
-   Here are some features that appeared in the 0.9.5 release (Oct/2008):
-     * Symmetric key encryption ciphers. ARC4, AES-128, AES-256,
-       blowfish, and 3des are supported. Salt and initialization vector
-       seeding is provided. These compliment the more widely used SSL and
-       SSH encryption access methods. SSVNC also supports these
-       encryption modes.
-     * Scaling differently along the X- and Y-directions. E.g. "-scale
-       1280x1024" or "-scale 0.8x0.75"    Also, "-geometry WxH" is an
-       alias for "-scale WxH"
-     * By having SSVNC version 1.0.21 or later available in your $PATH,
-       the -chatwindow option allows a UltraVNC Text Chat window to
-       appear on the local X11 console/display (this way the remote
-       viewer can chat with the person at the physical display; e.g.
-       helpdesk mode.) This also works on the Mac OS X console if the
-       Xquartz X11 server (enabled by default on leopard) is running for
-       the chatwindow.
-     * The HTTP Java viewer applet jar, classes/VncViewer.jar, has been
-       updated with an improved implementation based on the code used by
-       the classes/ssl applets.
-
-
-   Here are some features that appeared in the 0.9.4 release (Sep/2008):
-     * Improvements to the -find and -create X session finding or
-       creating modes: new desktop types and service redirection options.
-       Personal cupsd daemon and SSH port redirection helper for use with
-       SSVNC's Terminal Services feature.
-     * Reverse VNC connections via -connect work in the -find, -create
-       and related -display WAIT:... modes.
-     * Reverse VNC connections (either normal or SSL) can use a Web Proxy
-       or a SOCKS proxy, or a SSH connection, or even a CGI URL to make
-       the outgoing connection. See: -proxy. Forward connections can also
-       use: -ssh.
-     * Reverse VNC connections via the UltraVNC repeater proxy (either
-       normal or SSL) are supported. Use either the "-connect
-       repeater=ID:NNNN+host:port" or "-connect
-       repeater://host:port+ID:NNNN" notation. The SSVNC VNC viewer also
-       supports the UltraVNC repeater. Also, a perl repeater implemention
-       is here: ultravnc_repeater.pl
-     * Support for indexed colormaps (PseudoColor) with depths other than
-       8 (from 1 to 16 now work) for non-standard hardware. Option
-       "-advertise_truecolor" to handle some workaround in this mode.
-     * Support for the ZYWRLE encoding, this is the RealVNC ZRLE encoding
-       extended to do motion video and photo regions more efficiently by
-       way of a Wavelet based transformation.
-     * The -finddpy and -listdpy utilities help to debug and configure
-       the -find, -create, and -display WAIT:... modes.
-     * Some automatic detection of screen resizes are handled even if the
-       -xrandr option is not supplied.
-     * The -autoport options gives more control over the VNC port x11vnc
-       chooses.
-     * The -ping secs can be used to help keep idle connections alive.
-     * Pasting of the selection/clipboard into remote applications (e.g.
-       Java) has been improved.
-     * Fixed a bug if a client disconnects during the 'speed-estimation'
-       phase.
-     * To unset Caps_Lock, Num_Lock and raise all keys in the X server
-       use -clear_all.
-     * Usage with dvorak keyboards has been improved. See also: -xkb.
-     * The Java Viewer applet source code is now included in the
-       x11vnc-0.9.*.tar.gz tarball. This means you can now build the Java
-       viewer applet jar files from source. If you stopped shipping the
-       Java viewer applet jar files due to lack of source code, you can
-       start again.
-
-
-   Here are some features that appeared in the 0.9.3 release (Oct/2007):
-     * Viewer-side pixmap caching. A large area of pixels (at least 2-3
-       times as big as the framebuffer itself; the bigger the better...
-       default is 10X) is placed below the framebuffer to act as a
-       buffer/cache area for pixel data. The VNC CopyRect encoding is
-       used to move it around, so any viewer can take advantage of it.
-       Until we start modifying viewers you will be able to see the cache
-       area if you scroll down (this makes it easier to debug!) For
-       testing the default is "-ncache 10". The unix Enhanced TightVNC
-       Viewer ssvnc has a nice -ycrop option to help hide the pixel cache
-       area from view.
-
-
-   Here are some features that appeared in the 0.9.2 release (Jun/2007):
-     * Building with no OpenSSL libssl available (or with --without-ssl)
-       has been fixed.
-     * One can configure x11vnc via "./configure
-       --with-system-libvncserver" to use a system installed libvncserver
-       library instead of the one bundled in the release tarball.
-     * If UltraVNC file transfer or chat is detected, then VNC clients
-       are "pinged" more often to prevent these side channels from
-       becoming serviced too infrequently.
-     * In -unixpw mode in the username and password dialog no text will
-       be echoed if the first character sent is "Escape". This enables a
-       convenience feature in SSVNC to send the username and password
-       automatically.
-
-
-   Here are some features that appeared in the 0.9.1 release (May/2007):
-     * The UltraVNC Java viewer has been enhanced to support SSL (as the
-       TightVNC viewer had been previously.) The UltraVNC Java supports
-       ultravnc filetransfer, and so can be used as a VNC viewer on Unix
-       that supports ultravnc filetransfer. It is in the
-       classes/ssl/UltraViewerSSL.jar file (that is pointed to by
-       ultra.vnc.) The signed applet SignedUltraViewerSSL.jar version
-       (pointed to by ultrasigned.vnc) will be needed to access the local
-       drive if you are using it for file transfer via a Web browser.
-       Some other bugs in the UltraVNC Java viewer were fixed and a few
-       improvements to the UI made.
-     * A new Unix username login mode for VNC Viewers authenticated via a
-       Client SSL Certificate: "-users sslpeer=". The emailAddress
-       subject field is inspected for username@hostname and then acts as
-       though "-users +username" has been supplied. This way the Unix
-       username is identified by (i.e. simply extracted from) the Client
-       SSL Certificate. This could be useful with -find, -create and -svc
-       modes if you are also have set up and use VNC Client SSL
-       Certificate authentication.
-     * For external display finding/creating programs (e.g. WAIT:cmd=...)
-       if the VNC Viewer is authenticated via a Client SSL Certificate,
-       then that Certificate is available in the environment variable
-       RFB_SSL_CLIENT_CERT.
-
-
-   Here are some features that appeared in the 0.9 release (Apr/2007):
-     * VNC Service advertising via mDNS / ZeroConf / BonJour with the
-       Avahi client library. Enable via "-avahi" or "-zeroconf".
-     * Implementations of UltraVNC's TextChat, SingleWindow, and
-       ServerInput extensions (requires ultravnc viewer or ssvnc Unix
-       viewer.) They toggle the selection of a single window (-id), and
-       disable (friendly) user input and viewing (monitor blank) at the
-       VNC server.
-     * Short aliases "-find", "-create", "-svc", and "-xdmsvc" for
-       commonly used FINDCREATEDISPLAY usage modes.
-     * Reverse VNC connections (viewer listening) now work in SSL (-ssl)
-       mode.
-     * New options to control the Monitor power state and keyboard/mouse
-       grabbing: -forcedpms, -clientdpms, -noserverdpms, and -grabalways.
-     * A simple way to emulate inetd(8) to some degree via the "-loopbg"
-       option.
-     * Monitor the accuracy of XDAMAGE and apply "-noxdamage" if it is
-       not working well. OpenGL applications like like beryl and MythTv
-       have been shown to make XDAMAGE not work properly.
-     * For Java SSL connections involving a router/firewall port
-       redirection, an option -httpsredir to spare the user from needing
-       to include &PORT=NNN in the browser URL.
-
-
-   Here are some features that appeared in the 0.8.4 release (Feb/2007):
-     * Native Mac OS X Aqua/Quartz support. (i.e. OSXvnc alternative;
-       some activities are faster)
-     * A new login mode: "-display WAIT:cmd=FINDCREATEDISPLAY -unixpw
-       ..." that will Create a new X session (either virtual or real and
-       with or without a display manager, e.g. kdm) for the user if it
-       cannot find the user's X session display via the FINDDISPLAY
-       method. See the -svc and the -xdmsvc aliases.
-     * x11vnc can act as a VNC reflector/repeater using the "-reflect
-       host:N" option. Instead of polling an X display, the remote VNC
-       Server host:N is connected to and re-exported via VNC. This is
-       intended for use in broadcasting a display to many (e.g. > 16;
-       classroom or large demo) VNC viewers where bandwidth and other
-       resources are conserved by spreading the load over a number of
-       repeaters.
-     * Wireframe copyrect detection for local user activity (e.g. someone
-       sitting at the physical display moving windows) Use
-       -nowireframelocal to disable.
-     * The "-N" option couples the VNC Display number to the X Display
-       number. E.g. if your X DISPLAY is :2 then the VNC display will be
-       :2 (i.e. using port 5902.) If that port is taken x11vnc will exit.
-     * Option -nodpms to avoid problems with programs like KDE's
-       kdesktop_lock that keep restarting the screen saver every few
-       seconds.
-     * To automatically fix the common mouse motion problem on XINERAMA
-       (multi-headed) displays, the -xwarppointer option is enabled by
-       default when XINERAMA is active.
-
-   If you have a Mac please try out the native Mac OS X support, build
-   with "./configure --without-x", or download a binary mentioned above,
-   (even if you don't plan on ever using it in this mode!), and let me
-   know how it went. Thanks.
-
-
-   Here are some features that appeared in the 0.8.3 release (Nov/2006):
-     * The -ssl option provides SSL encryption and authentication
-       natively via the www.openssl.org library. One can use from a
-       simple self-signed certificate server certificate up to full CA
-       and client certificate authentication schemes.
-     * Similar to -ssl, the -stunnel option starts up a SSL tunnel server
-       stunnel (that must be installed separately on the system:
-       stunnel.mirt.net ) to allow only encrypted SSL connections from
-       the network.
-     * The -sslverify option allows for authenticating VNC clients via
-       their certificates in either -ssl or -stunnel modes.
-     * Certificate creation and management tools are provide in the
-       -sslGenCert, -sslGenCA, and related options.
-     * An SSL enabled Java applet VNC Viewer applet is provided by x11vnc
-       in classes/ssl/VncViewer.jar. In addition to normal HTTP, the
-       applet may be loaded into the web browser via HTTPS (HTTP over
-       SSL.) (one can use the VNC port, e.g. https://host:5900/, or also
-       the separate -https port option.) A wrapper shell script
-       ss_vncviewer is also provided that sets up a stunnel client-side
-       tunnel on Unix systems. See Enhanced TightVNC Viewer (SSVNC) for
-       other SSL/SSH viewer possibilities.
-     * The -unixpw option supports Unix username and password
-       authentication (a simpler variant is the -unixpw_nis option that
-       works in environments where the encrypted passwords are readable,
-       e.g. NIS.) The -ssl or -localhost + -stunnel options are enforced
-       in this mode to prevent password sniffing. As a convenience, these
-       requirements are lifted if a SSH tunnel can be deduced (but
-       -localhost still applies.)
-     * Coupling -unixpw with "-display WAIT:cmd=FINDDISPLAY" or "-display
-       WAIT:cmd=FINDCREATEDISPLAY" provides a way to allow a user to
-       login with their UNIX password and have their display connected to
-       automatically. See the -svc and the -xdmsvc aliases.
-     * Hooks are provided in the -unixpw_cmd and "-passwdfile
-       cmd:,custom:..." options to allow you to supply your own
-       authentication and password lookup programs.
-     * x11vnc can be configured and built to not depend on X11 libraries
-       "./configure --without-x" for -rawfb only operation (e.g. embedded
-       linux console devices.)
-     * The -rotate option enables you to rotate or reflect the screen
-       before exporting via VNC. This is intended for use on handhelds
-       and other devices where the rotation orientation is not "natural".
-     * The "-ultrafilexfer" alias is provided and improved UltraVNC
-       filetransfer rates have been achieved.
-     * Under the "-connect_or_exit host" option x11vnc will exit
-       immediately unless the reverse connection to host succeeds. The
-       "-rfbport 0" option disables TCP listening for connections (useful
-       for this mode.)
-     * The "-rawfb rand" and "-rawfb none" options are useful for testing
-       automation scripts, etc., without requiring a full desktop.
-     * Reduced spewing of information at startup, use "-verbose" (also
-       "-v") to turn it back on for debugging or if you are going to send
-       me a problem report.
-
-   Here are some Previous Release Notes
-     _________________________________________________________________
-
-    Some Notes:
-
-   Both a client and a server:   It is sometimes confusing to people that
-   x11vnc is both a client and a server at the same time. It is an X
-   client because it connects to the running X server to do the screen
-   polls. Think of it as a rather efficient "screenshot" program running
-   continuously. It is a server in the sense that it is a VNC server that
-   VNC viewers on the network can connect to and view the screen
-   framebuffer it manages.
-
-   When trying to debug problems, remember to think of both roles. E.g.
-   "how is x11vnc connecting to the X server?", "how is the vncviewer
-   connecting to x11vnc?", "what permits/restricts the connection?". Both
-   links may have reachability, permission, and other issues.
-
-   Network performance:   Whether you are using Xvnc or x11vnc it is
-   always a good idea to have a solid background color instead of a
-   pretty background image. Each and every re-exposure of the background
-   must be resent over the network: better to have that background be a
-   solid color that compresses very well compared to a photo image. (This
-   is one place where the X protocol has an advantage over the VNC
-   protocol.) I suggest using xsetroot, dtstyle or similar utility to set
-   a solid background while using x11vnc. You can turn the pretty
-   background image back on when you are using the display directly.
-   Update: As of Feb/2005 x11vnc has the -solid [color] option that works
-   on recent GNOME, KDE, and CDE and also on classic X (background image
-   is on the root window.) Update: As of Oct/2007 x11vnc has the -ncache
-   option that does a reasonable job caching the background (and other)
-   pixmap data on the viewer side.
-
-   I also find the TightVNC encoding gives the best response for my usage
-   (Unix <-> Unix over cable modem.) One needs a tightvnc-aware vncviewer
-   to take advantage of this encoding.
-
-   TCP port issues:   Notice the lines
-  18/07/2003 14:36:31 Autoprobing selected port 5900
-  PORT=5900
-
-   in the output. 5900 is the default VNC listening port (just like 6000
-   is X11's default listening port.) Had port 5900 been taken by some
-   other application, x11vnc would have next tried 5901. That would mean
-   the viewer command above should be changed to vncviewer
-   far-away.east:1. You can force the port with the "-rfbport NNNN"
-   option where NNNN is the desired port number. If that port is already
-   taken, x11vnc will exit immediately. The "-N" option will try to match
-   the VNC display number to the X display.   (also see the "SunRay
-   Gotcha" note below)
-
-   Options:   x11vnc has (far too) many features that may be activated
-   via its command line options. Useful options are, e.g., -scale to do
-   server-side scaling, and -rfbauth passwd-file to use VNC password
-   protection (the vncpasswd or storepasswd programs, or the x11vnc
-   -storepasswd option can be used to create the password file.)
-
-   Algorithm:   How does x11vnc do it? Rather brute-forcedly: it
-   continuously polls the X11 framebuffer for changes using
-   XShmGetImage(). When changes are discovered, it instructs libvncserver
-   which rectangular regions of the framebuffer have changed, and
-   libvncserver compresses the changes and sends them off to any
-   connected VNC viewers. A number of applications do similar things,
-   such as x0rfbserver, krfb, x0vncserver, vino. x11vnc uses a 32 x 32
-   pixel tile model (the desktop is decomposed into roughly 1000 such
-   tiles), where changed tiles are found by pseudo-randomly polling 1
-   pixel tall horizontal scanlines separated vertically by 32 pixels.
-   This is a surprisingly effective algorithm for finding changed
-   regions. For keyboard and mouse user input the XTEST extension is used
-   to pass the input events to the X server. To detect XBell "beeps" the
-   XKEYBOARD extension is used. If available, the XFIXES extension is
-   used to retrieve the current mouse cursor shape. Also, if available
-   the X DAMAGE extension is used to receive hints from the X server
-   where modified regions on the screen are. This greatly reduces the
-   system load when not much is changing on the screen and also improves
-   how quickly the screen is updated.
-
-   Barbershop mirrors effect:   What if x11vnc is started up, and
-   vncviewer is then started up on the same machine and displayed on the
-   same display x11vnc is polling? One might "accidentally" do this when
-   first testing out the programs. You get an interesting
-   recursive/feedback effect where vncviewer images keep popping up each
-   one contained in the previous one and slightly shifted a bit by the
-   window manager decorations. There will be an even more interesting
-   effect if -scale is used. Also, if the XKEYBOARD is supported and the
-   XBell "beeps" once, you get an infinite loop of beeps going off.
-   Although all of this is mildly exciting it is not much use: you will
-   normally run and display the viewer on a different machine!
-     _________________________________________________________________
-
-    Sun Ray Notes:
-
-   You can run x11vnc on your (connected or disconnected) SunRay session.
-   Here are some notes on SunRay usage with x11vnc.
-
-     _________________________________________________________________
-
-    Limitations:
-
-     * Due to the polling nature, some activities (opaque window moves,
-       scrolling), can be pretty choppy/ragged and others (exposures of
-       large areas) slow. Experiment with interacting a bit differently
-       than you normally do to minimize the effects (e.g. do fullpage
-       paging rather than line-by-line scrolling, and move windows in a
-       single, quick motion.) Recent work has provided the
-       -scrollcopyrect and -wireframe speedups using the CopyRect VNC
-       encoding and other things, but they only speed up some activities,
-       not all.
-     * A rate limiting factor for x11vnc performance is that graphics
-       hardware is optimized for writing, not reading (x11vnc reads the
-       video framebuffer for the screen image data.) The difference can
-       be a factor of 10 to 1000, and so it usually takes about 0.5-1 sec
-       to read in the whole video hardware framebuffer (e.g. 5MB for
-       1280x1024 at depth 24 with a read rate of 5-10MB/sec.) So whenever
-       activity changes most of the screen (e.g. moving or iconifying a
-       large window) there is a delay of 0.5-1 sec while x11vnc reads the
-       changed regions in.
-       A slow framebuffer read rate will often be the performance
-       bottleneck on a fast LAN (whereas on slower links the reduced
-       network bandwidth becomes the bottleneck.)
-       Note: A quick way to get a 2X speedup of this for x11vnc is to
-       switch your X server from depth 24 (32bpp) to depth 16 (16bpp.)
-       You get a 4X speedup going to 8bpp, but the lack of color cells is
-       usually unacceptable.
-       To get a sense of the read and write speeds of your video card,
-       you can run benchmarks like: "x11perf -getimage500",  "x11perf
-       -putimage500",  "x11perf -shmput500" and for XFree86 displays with
-       direct graphics access the "dga" command (press "b" to run the
-       benchmark and then after a few seconds press "q" to quit.) Even
-       this "dd if=/dev/fb0 of=/dev/null" often gives a good estimate.
-       x11vnc also prints out its estimate:
-  28/02/2009 11:11:07 Autoprobing TCP port
-  28/02/2009 11:11:07 Autoprobing selected port 5900
-  28/02/2009 11:11:08 fb read rate: 10 MB/sec
-  28/02/2009 11:11:08 screen setup finished.
-       We have seen a few cases where the hardware fb read speed is
-       greater than 65 MB/sec: on high end graphics workstations from SGI
-       and Sun, and also from a Linux user using nvidia proprietary
-       drivers for his nvidia video card. Update 2008: thankfully, these
-       sped up drivers are becoming more common on Linux and *BSD systems
-       and that makes x11vnc run somewhat more quickly. Sometimes they
-       have a read rate of over 400 MB/sec.
-       On XFree86/Xorg it is actually possible to increase the
-       framebuffer read speed considerably (10-100 times) by using the
-       Shadow Framebuffer (a copy of the framebuffer is kept in main
-       memory and this can be read much more quickly.) To do this one
-       puts the line Option "ShadowFB" "true" in the Device section of
-       the /etc/X11/XF86Config or /etc/X11/xorg.conf file. Note that this
-       disables 2D acceleration at the physical display and so that might
-       be unacceptable if one plays games, etc. on the machine's local
-       display. Nevertheless this could be handy in some circumstances,
-       e.g. if the slower speed while sitting at the physical display was
-       acceptable (this seems to be true for most video cards these
-       days.) Unfortunately it does not seem shadowfb can be turned on
-       and off dynamically...
-       Another amusing thing one can do is use Xvfb as the X server, e.g.
-       "xinit $HOME/.xinitrc -- /usr/X11R6/bin/Xvfb :1 -screen 0
-       1024x768x16" x11vnc can poll Xvfb efficiently via main memory.
-       It's not exactly clear why one would want to do this instead of
-       using vncserver/Xvnc, (perhaps to take advantage of an x11vnc
-       feature, such as framebuffer scaling or built-in SSL encryption),
-       but we mention it because it may be of use for special purpose
-       applications. You may need to use the "-cc 4" option to force Xvfb
-       to use a TrueColor visual instead of DirectColor. See also the
-       description of the -create option that does all of this
-       automatically for you (be sure to install the Xvfb package, e.g.
-       apt-get install xvfb.)
-       Also, a faster and more accurate way is to use the "dummy"
-       Xorg/XFree86 device driver (or our Xdummy wrapper script.) See
-       this FAQ for details.
-     * Somewhat surprisingly, the X11 mouse (cursor) shape is write-only
-       and cannot be queried from the X server. So traditionally in
-       x11vnc the cursor shape stays fixed at an arrow. (see the "-cursor
-       X" and "-cursor some" options, however, for a partial hack for the
-       root window, etc.) However, on Solaris using the SUN_OVL overlay
-       extension, x11vnc can show the correct mouse cursor when the
-       -overlay option is also supplied. A similar thing is done on IRIX
-       as well when -overlay is supplied.
-       More generally, as of Dec/2004 x11vnc supports the new XFIXES
-       extension (in Xorg and Solaris 10) to query the X server for the
-       exact cursor shape, this works pretty well except that cursors
-       with transparency (alpha channel) need to approximated to solid
-       RGB values (some cursors look worse than others.)
-     * Audio from applications is of course not redirected (separate
-       redirectors do exist, e.g. esd, see the FAQ on this below.) The
-       XBell() "beeps" will work if the X server supports the XKEYBOARD
-       extension. (Note that on Solaris XKEYBOARD is disabled by default.
-       Passing +kb to Xsun enables it.)
-     * The scroll detection algorithm for the -scrollcopyrect option can
-       give choppy or bunched up transient output and occasionally
-       painting errors.
-     * Using -threads can expose some bugs/crashes in libvncserver.
-
-   Please feel free to contact me if you have any questions, problems, or
-   comments about x11vnc, etc. Please be polite, thorough, and not
-   demanding (sadly, the number of people contacting me that are rude and
-   demanding is increasing dramatically.)
-   Also, some people ask if they can make a donation, see this link for
-   that.

-
-    x11vnc FAQ:
-
-
-   [Building and Starting]
-
-   Q-1: I can't get x11vnc to start up. It says "XOpenDisplay failed
-   (null)" or "Xlib: connection to ":0.0" refused by server Xlib: No
-   protocol specified" and then exits. What do I need to do? 
-
-   Q-2: I can't get x11vnc and/or libvncserver to compile. 
-
-   Q-3: I just built x11vnc successfully, but when I use it my keystrokes
-   and mouse button clicks are ignored  (I am able to move the mouse
-   though.) 
-
-   Q-4: Help, I need to run x11vnc on Solaris 2.5.1 (or other old
-   Unix/Linux) and it doesn't compile! 
-
-   Q-5: Where can I get a precompiled x11vnc binary for my Operating
-   System? 
-

-   documentation on how to use them? 
-
-   Q-8: I don't like typing arcane command line options every time I
-   start x11vnc. What can I do? Is there a config file? Or a GUI? 
-
-   Q-9: How can I get the GUI to run in the System Tray, or at least be a
-   smaller, simpler icon? 
-
-   Q-10: How can I get x11vnc to listen on a different port besides the

-
-   [Win2VNC Related]
-
-   Q-20: I have two separate machine displays in front of me, one Windows
-   the other X11: can I use x11vnc in combination with Win2VNC in
-   dual-screen mode to pass the keystrokes and mouse motions to the X11
-   display? 
-
-   Q-21: I am running Win2VNC on my Windows machine and "x11vnc -nofb" on

-   Q-22: Can I run "x11vnc -nofb" on a Mac OS X machine to redirect mouse
-   and keyboard input to it from Windows and X11 machines via Win2VNC and
-   x2vnc, respectively? 
-
-   [Color Issues]
-
-   Q-23: The X display I run x11vnc on is only 8 bits per pixel (bpp)
-   PseudoColor (i.e. only 256 distinct colors.) The x11vnc colors may
-   start out OK, but after a while they are incorrect in certain windows.
-   
-   Q-24: Color problems: Why are the colors for some windows incorrect in
-   x11vnc? BTW, my X display has nice overlay/multi-depth visuals of
-   different color depths: e.g. there are both depth 8 and 24 visuals
-   available at the same time. 
-
-   Q-25: I am on a high color system (depth >= 24) but I seem to have
-   colormap problems. They either flash or everything is very dark. 
-
-   Q-26: How do I figure out the window id to supply to the -id windowid
-   option? 
-
-   Q-27: Why don't menus or other transient windows come up when I am
-   using the -id windowid option to view a single application window? 
-
-   Q-28: My X display is depth 24 at 24bpp (instead of the normal depth
-   24 at 32bpp.) I'm having lots of color and visual problems with x11vnc
-   and/or vncviewer. What's up? 
-
-   [Xterminals]
-
-   Q-29: Can I use x11vnc to view and interact with an Xterminal (e.g.
-   NCD) that is not running UNIX and so x11vnc cannot be run on it
-   directly? 
-
-   Q-30: How do I get my X permissions (MIT-MAGIC-COOKIE file) correct
-   for a Unix/Linux machine acting as an Xterminal? 
-
-   [Sun Rays]
-
-   Q-31: I'm having trouble using x11vnc with my Sun Ray session. 
-
-   [Remote Control]

-   Q-33: Can I change settings in x11vnc without having to restart it?
-   Can I remote control it? 
-
-   [Security and Permissions]
-
-   Q-34: How do I create a VNC password for use with x11vnc? 
-
-   Q-35: Can I make it so -storepasswd doesn't show my password on the
-   screen? 
-
-   Q-36: Can I have two passwords for VNC viewers, one for full access
-   and the other for view-only access to the display? 
-
-   Q-37: Can I have as many full-access and view-only passwords as I
-   like? 
-
-   Q-38: Does x11vnc support Unix usernames and passwords? Can I further
-   limit the set of Unix usernames who can connect to the VNC desktop? 
-
-   Q-39: Can I supply an external program to provide my own custom login
-   method (e.g. Dynamic/One-time passwords or non-Unix (LDAP) usernames
-   and passwords)? 
-
-   Q-40: Why does x11vnc exit as soon as the VNC viewer disconnects? And
-   why doesn't it allow more than one VNC viewer to connect at the same
-   time? 
-
-   Q-41: Can I limit which machines incoming VNC clients can connect
-   from? 
-
-   Q-42: How do I build x11vnc/libvncserver with libwrap (tcp_wrappers)
-   support? 
-
-   Q-43: Can I have x11vnc only listen on one network interface (e.g.
-   internal LAN) rather than having it listen on all network interfaces
-   and relying on -allow to filter unwanted connections out? 
-
-   Q-44: Now that -localhost implies listening only on the loopback
-   interface, how I can occasionally allow in a non-localhost via the -R
-   allowonce remote control command? 
-
-   Q-45: Can I fine tune what types of user input are allowed? E.g. have
-   some users just be able to move the mouse, but not click or type
-   anything? 
-
-   Q-46: Can I prompt the user at the local X display whether the
-   incoming VNC client should be accepted or not? Can I decide to make
-   some clients view-only? How about running an arbitrary program to make
-   the decisions? 
-
-   Q-47: I start x11vnc as root because it is launched via inetd(8) or a
-   display manager like gdm(1). Can I have x11vnc later switch to a
-   different user? 
-
-   Q-48: I use a screen-lock when I leave my workstation (e.g.
-   xscreensaver or xlock.) When I remotely access my workstation desktop
-   via x11vnc I can unlock the desktop fine, but I am worried people will
-   see my activities on the physical monitor. What can I do to prevent
-   this, or at least make it more difficult? 
-
-   Q-49: Can I have x11vnc automatically lock the screen when I
-   disconnect the VNC viewer? 
-

-   workstations behind a firewall? 
-
-   Q-57: Can I create and use my own SSL Certificate Authority (CA) with
-   x11vnc? 
-
-   [Display Managers and Services]

-
-   Q-59: How can I use x11vnc to connect to an X login screen like xdm,
-   GNOME gdm, KDE kdm, or CDE dtlogin? (i.e. nobody is logged into an X
-   session yet.) 
-
-   Q-60: Can I run x11vnc out of inetd(8)? How about xinetd(8)? 
-
-   Q-61: Can I have x11vnc advertise its VNC service and port via mDNS /
-   Zeroconf (e.g. Avahi) so VNC viewers on the local network can detect
-   it automatically? 
-
-   Q-62: Can I have x11vnc allow a user to log in with her UNIX username
-   and password and then have it find her X session display on that
-   machine and then attach to it? How about starting an X session if one
-   cannot be found? 
-
-   Q-63: Can I have x11vnc restart itself after it terminates? 
-
-   Q-64: How do I make x11vnc work with the Java VNC viewer applet in a
-   web browser? 
-

-
-   Q-66: Can reverse connections be made to go through a Web or SOCKS
-   proxy or SSH? 
-
-   Q-67: Can x11vnc provide a multi-user desktop web login service as an
-   Apache CGI or PHP script?

-
-   Q-69: How can I use x11vnc on "headless" machines? Why might I want
-   to? 
-
-   [Resource Usage and Performance]
-
-   Q-70: I have lots of memory, but why does x11vnc fail with    shmget:
-   No space left on device    or    Minor opcode of failed request: 1
-   (X_ShmAttach)? 
-

-   things really bog down (unless I do the drag in a single, quick
-   motion.) Is there anything to do to improve things? 
-
-   Q-77: Why not do something like wireframe animations to avoid the
-   windows "lurching" when being moved or resized? 
-
-   Q-78: Can x11vnc try to apply heuristics to detect when a window is
-   scrolling its contents and use the CopyRect encoding for a speedup? 
-
-   Q-79: Can x11vnc do client-side caching of pixel data? I.e. so when

-
-   [Mouse Cursor Shapes]
-
-   Q-81: Why isn't the mouse cursor shape (the little icon shape where

-
-   Q-82: When using XFIXES cursorshape mode, some of the cursors look
-   really bad with extra black borders around the cursor and other cruft.
-   How can I improve their appearance? 
-
-   Q-83: In XFIXES mode, are there any hacks to handle cursor
-   transparency ("alpha channel") exactly? 
-
-   [Mouse Pointer]
-
-   Q-84: Why does the mouse arrow just stay in one corner in my
-   vncviewer, whereas my cursor (that does move) is just a dot? 
-
-   Q-85: Can I take advantage of the TightVNC extension to the VNC
-   protocol where Cursor Positions Updates are sent back to all connected
-   clients (i.e. passive viewers can see the mouse cursor being moved
-   around by another viewer)? 
-
-   Q-86: Is it possible to swap the mouse buttons (e.g. left-handed
-   operation), or arbitrarily remap them? How about mapping button clicks
-   to keystrokes, e.g. to partially emulate Mouse wheel scrolling? 
-
-   [Keyboard Issues]
-
-   Q-87: How can I get my AltGr and Shift modifiers to work between
-   keyboards for different languages? 
-
-   Q-88: When I try to type a "<" (i.e. less than) instead I get ">"
-   (i.e. greater than)! Strangely, typing ">" works OK!! 
-
-   Q-89: Extra Character Inserted, E.g.: When I try to type a "<" (i.e.
-   less than) instead I get "<," (i.e. an extra comma.) 
-
-   Q-90: I'm using an "international" keyboard (e.g. German "de", or
-   Danish "dk") and the -modtweak mode works well if the VNC viewer is
-   run on a Unix/Linux machine with a similar keyboard.   But if I run
-   the VNC viewer on Unix/Linux with a different keyboard (e.g. "us") or
-   Windows with any keyboard, I can't type some keys like:   "@", "$",
-   "<", ">", etc. How can I fix this? 
-
-   Q-91: When typing I sometimes get double, triple, or more of my
-   keystrokes repeated. I'm sure I only typed them once, what can I do? 
-

-   keystrokes!! 
-
-   Q-93: After using x11vnc for a while, I find that I cannot type some
-   (or any) characters or my mouse clicks and drags no longer have any
-   effect, or they lead to strange effects. What happened? 
-
-   Q-94: The machine where I run x11vnc has an AltGr key, but the local
-   machine where I run the VNC viewer does not. Is there a way I can map
-   a local unused key to send an AltGr? How about a Compose key as well? 
-
-   Q-95: I have a Sun machine I run x11vnc on. Its Sun keyboard has just
-   one Alt key labelled "Alt" and two Meta keys labelled with little
-   diamonds. The machine where I run the VNC viewer only has Alt keys.
-   How can I send a Meta keypress? (e.g. emacs needs this) 
-
-   Q-96: Running x11vnc on HP-UX I cannot type "#" I just get a "3"
-   instead.

-   special purpose application or a very large screen.) 
-
-   Q-104: Does x11vnc support the XRANDR (X Resize, Rotate and
-   Reflection) extension? Whenever I rotate or resize the screen x11vnc
-   just seems to crash. 
-
-   Q-105: Independent of any XRANDR, can I have x11vnc rotate and/or
-   reflect the screen that the VNC viewers see? (e.g. for a handheld
-   whose screen is rotated 90 degrees.) 
-

-   everything flashing around randomly? 
-
-   Q-107: I use Linux Virtual Terminals (VT's) to implement 'Fast User
-   Switching' between users' sessions (e.g. Betty is on Ctrl-Alt-F7,
-   Bobby is on Ctrl-Alt-F8, and Sid is on Ctrl-Alt-F1: they use those
-   keystrokes to switch between their sessions.)   How come the view in a
-   VNC viewer connecting to x11vnc is either completely black or
-   otherwise all messed up unless the X session x11vnc is attached to is
-   in the active VT? 
-
-   Q-108: I am using x11vnc where my local machine has "popup/hidden

-
-   [Building and Starting]
-
-   Q-1: I can't get x11vnc to start up. It says "XOpenDisplay failed
-   (null)" or "Xlib: connection to ":0.0" refused by server Xlib: No
-   protocol specified" and then exits. What do I need to do?
-
-   For the former error, you need to specify the X display to connect to
-   (it also needs to be on the same machine the x11vnc process is to run
-   on.) Set your DISPLAY environment variable (or use the -display
-   option) to specify it. Nearly always the correct value will be ":0"
-   (in fact, x11vnc will now assume :0 if given no other information.)
-
-
-   For the latter error, you need to set up the X11 permissions
-   correctly.
-
-   To make sure X11 permissions are the problem do this simple test:
-   while sitting at the physical X display open a terminal window
-   (gnome-terminal, xterm, etc.) You should be able to run x11vnc
-   successfully without any need for special steps or command line
-   options in that terminal (i.e. just type "x11vnc".) If that works OK
-   then you know X11 permissions are the only thing preventing it from
-   working when you try to start x11vnc via, say, a remote shell.
-
-   How to Solve:  See the xauth(1), Xsecurity(7), and xhost(1) man pages
-   or this Howto for much info on X11 permissions. For example, you may
-   need to set your XAUTHORITY environment variable (or use the -auth
-   option) to point to the correct MIT-MAGIC-COOKIE file (e.g.
-   /home/joe/.Xauthority or /var/gdm/:0.Xauth or /var/lib/kdm/A:0-crWk72K
-   or /tmp/.gdmzndVlR, etc, etc.), or simply be sure you run x11vnc as
-   the correct user (i.e. the user who is logged into the X session you
-   wish to view.)
-
-   Note: The MIT cookie file contains the secret key that allows x11vnc
-   to connect to the desired X display.
-
-   If, say, sshd has set XAUTHORITY to point to a random file it has
-   created for X forwarding that will cause problems. (Under some
-   circumstances even su(1) and telnet(1) can set XAUTHORITY. See also
-   the gdm parameter NeverPlaceCookiesOnNFS that sets XAUTHORITY to a
-   random filename in /tmp for the whole X session.)
-
-   Running x11vnc as root is often not enough: you need to know where the
-   MIT-MAGIC-COOKIE file for the desired X display is.
-
-   Example solution:
-  x11vnc -display :0 -auth /var/gdm/:0.Xauth
-
-   (this is for the display manager gdm and requires root permission to
-   read the gdm cookie file, see this faq for other display manager
-   cookie file names.)
-
-   Note as of Feb/2007 you can also try the -find option instead of
-   "-display ..." and see if that finds your display and Xauthority.
-
-   Less safe, but to avoid figuring out where the correct XAUTHORITY file
-   is, if the person sitting at the physical X session types "xhost
-   +localhost" then one should be able to attach x11vnc to the session
-   (from the same machine.) The person could then type "xhost -localhost"
-   after x11vnc has connected to go back to the default permissions.
-   Also, for some situations the "-users lurk=" option may soon be of use
-   (please read the documentation on the -users option.)
-
-   To test out your X11 permissions from a remote shell, set DISPLAY and
-   possibly XAUTHORITY (see your shell's man page, bash(1), tcsh(1), on
-   how to set environment variables) and type xdpyinfo in the same place
-   you will be typing (or otherwise running) x11vnc. If information is
-   printed out about the X display (screen sizes, supported extensions,
-   color visuals info) that means the X11 permissions are set up
-   properly: xdpyinfo successfully connected to DISPLAY! You could also
-   type xclock and make sure no errors are reported (a clock should
-   appear on the X display, press Ctrl-C to stop it.) If these work, then
-   typing "x11vnc" in the same environment should also work.
-
-   Important: if you cannot get your X11 permissions so that the xdpyinfo
-   or xclock tests work, x11vnc also will not work (all of these X
-   clients must be allowed to connect to the X server to function
-   properly.)
-
-   Firewalls: Speaking of permissions, it should go without saying that
-   the host-level firewall will need to be configured to allow
-   connections in on a port. E.g. 5900 (default VNC port) or 22 (default
-   SSH port for tunnelling VNC.) Most systems these days have firewalls
-   turned on by default, so you will actively have to do something to
-   poke a hole in the firewall at the desired port number. See your
-   system administration tool for Firewall settings (Yast, Firestarter,
-   etc.)
-
-
-   Q-2: I can't get x11vnc and/or libvncserver to compile.
-
-   Make sure you have gcc (or other C compiler) and all of the required
-   libraries and the corresponding -dev/-devel packages installed. These
-   include Xorg/XFree86, libX11, libjpeg, libz, libssl, ... and don't
-   forget the devs: libjpeg-dev, libssl-dev ...
-
-   The most common build problem that people encounter is that the
-   necessary X11 libraries are installed on their system however it does
-   not have the corresponding -dev/-devel packages installed. These dev
-   packages include C header files and build-time .so symlink. It is a
-   shame the current trend in distros is to not install the dev package
-   by default when the the library runtime package is installed... (it
-   diminishes the power of open source)
-
-   As of Nov/2006 here is a list of libraries that x11vnc usually likes
-   to use:
-libc.so        libX11.so       libXtst.so       libXext.so
-libXfixes.so   libXdamage.so   libXinerama.so   libXrandr.so
-libz.so        libjpeg.so      libpthread.so
-libssl.so      libcrypto.so    libcrypt.so
-
-   although x11vnc will be pretty usable with the subset: libc.so,
-   libX11.so, libXtst.so, libXext.so, libz.so, and libjpeg.so.
-
-   After running the libvncserver configure, carefully examine the output
-   and the messages in the config.log file looking for missing
-   components. For example, if the configure output looks like:
-  checking how to run the C preprocessor... gcc -E
-  checking for X... no
-  checking for XkbSelectEvents in -lX11... no
-  checking for XineramaQueryScreens in -lXinerama... no
-  checking for XTestFakeKeyEvent in -lXtst... no
-
-   or even worse:
-  checking for C compiler default output file name... configure: error:
-  C compiler cannot create executables
-  See `config.log' for more details.
-
-   there is quite a bit wrong with the build environment. Hopefully
-   simply adding -dev packages and/or gcc or make will fix it.
-
-   For Debian the list seems to be:
-  gcc
-  make
-  libc6-dev
-  libjpeg8-dev           (formerly libjpeg62-dev)
-  libx11-dev
-  x11proto-core-dev      (formerly x-dev)
-  libxext-dev
-  libxtst-dev
-  libxdamage-dev
-  libxfixes-dev
-  libxrandr-dev
-  libxinerama-dev
-  libxss-dev             (formerly xlibs-static-dev)
-  zlib1g-dev
-  libssl-dev
-  libavahi-client-dev
-  linux-libc-dev         (only needed for linux console rawfb support)
-
-   Note that depending on your OS version the above names may have been
-   changed and/or additional packages may be needed.
-
-   For Redhat the list seems to be:
-  gcc
-  make
-  glibc-devel
-  libjpeg-devel
-  libX11-devel
-  xorg-x11-proto-devel
-  libXdamage-devel
-  libXfixes-devel
-  libXrandr-devel
-  zlib-devel
-  openssl-devel
-  avahi-devel
-  kernel-headers         (only needed for linux console rawfb support)
-
-   For other distros or OS's the package names may not be the same but
-   will look similar. Also, distros tend to rename packages as well so
-   the above list may be out of date. So only use the above lists as
-   hints for the package names that are needed.
-
-   Have a look at Misc. Build Problems for additional fixes.
-
-   Note: there is growing trend in Linux and other distros to slice up
-   core X11 software into more and smaller packages. So be prepared for
-   more headaches compiling software...
-
-
-   Q-3: I just built x11vnc successfully, but when I use it my keystrokes
-   and mouse button clicks are ignored  (I am able to move the mouse
-   though.)
-
-   This is most likely due to you not having a working build environment
-   for the XTEST client library libXtst.so. The library is probably
-   present on your system, but the package installing the build header
-   file is missing.
-
-   If you were watching carefully while configure was running you would
-   have seen:
-  checking for XTestFakeKeyEvent in -lXtst... no
-
-   The solution is to add the necessary build environment package (and
-   the library package if that is missing too.) On Debian the build
-   package is libxtst-dev. Other distros/OS's may have it in another
-   package.
-
-   x11vnc will build without support for this library (e.g. perhaps one
-   wants a view-only x11vnc on a stripped down or embedded system...) And
-   at runtime it will also continue to run even if the X server it
-   connects to does not support XTEST. In both cases it cannot inject
-   keystrokes or button clicks since XTEST is needed for that (it can
-   still move the mouse pointer using the X API XWarpPointer().)
-
-   You will see a warning message something like this at run time:
-  20/03/2005 22:33:09 WARNING: XTEST extension not available (either missing fr
-om
-  20/03/2005 22:33:09   display or client library libXtst missing at build time
-.)
-  20/03/2005 22:33:09   MOST user input (pointer and keyboard) will be DISCARDE
-D.
-  20/03/2005 22:33:09   If display does have XTEST, be sure to build x11vnc wit
-h
-  20/03/2005 22:33:09   a working libXtst build environment (e.g. libxtst-dev,
-  20/03/2005 22:33:09   or other packages.)
-  20/03/2005 22:33:09 No XTEST extension, switching to -xwarppointer mode for
-  20/03/2005 22:33:09   pointer motion input.
-
-   Also, as of Nov/2006 there will be a configure build time warning as
-   well:
-  ...
-  checking for XFixesGetCursorImage in -lXfixes... yes
-  checking for XDamageQueryExtension in -lXdamage... yes
-  configure: WARNING:
-  ==========================================================================
-  A working build environment for the XTEST extension was not found (libXtst).
-  An x11vnc built this way will be only barely usable.  You will be able to
-  move the mouse but not click or type.  There can also be deadlocks if an
-  application grabs the X server.
-
-  It is recommended that you install the necessary development packages
-  for XTEST (perhaps it is named something like libxtst-dev) and run
-  configure again.
-  ==========================================================================

-
-   Q-4: Help, I need to run x11vnc on Solaris 2.5.1 (or other old
-   Unix/Linux) and it doesn't compile!
-
-   We apologize that x11vnc does not build cleanly on older versions of
-   Solaris, Linux, etc.: very few users are on these old releases.
-
-   We have heard that since Dec/2004 a Solaris 2.6 built x11vnc will run
-   on Solaris Solaris 2.5 and 2.5.1 (since a workaround for XConvertCase
-   is provided.)
-
-   In any event, here is a workaround for Solaris 2.5.1 (and perhaps
-   earlier and perhaps non-Solaris):
-
-   First use the environment settings (CPPFLAGS, LDFLAGS, etc.) in the
-   above Solaris build script to run the configure command. That should
-   succeed without failure. Then you have to hand edit the autogenerated
-   rfb/rfbconfig.h file in the source tree, and just before the last
-   #endif at the bottom of that file insert these workaround lines:
-struct timeval _tmp_usleep_tv;
-#define usleep(x) \
-    _tmp_usleep_tv.tv_sec  = (x) / 1000000; \
-    _tmp_usleep_tv.tv_usec = (x) % 1000000; \
-    select(0, NULL, NULL, NULL, &_tmp_usleep_tv);
-int gethostname(char *name, int namelen);
-long random();
-int srandom(unsigned int seed);
-#undef LIBVNCSERVER_HAVE_LIBPTHREAD
-#define SHUT_RDWR 2
-typedef unsigned int in_addr_t;
-#define snprintf(a, n, args...) sprintf((a), ## args)
-
-   Then run make with the Solaris build script environment, everything
-   should compile without problems, and the resulting x11vnc binary
-   should work OK. If some non-x11vnc related programs fail (e.g. test
-   programs) and the x11vnc binary is not created try "make -k" to have
-   it keep going. Similar sorts of kludges in rfb/rfbconfig.h can be done
-   on other older OS (Solaris, Linux, ...) releases.
-
-   Here are some notes for similar steps that need to be done to build on
-   SunOS 4.x
-
-   Please let us know if you had to use the above workaround (and whether
-   it worked or not.) If there is enough demand we will try to push clean
-   compilations back to earlier Solaris, Linux, etc, releases.
-
-
-   Q-5: Where can I get a precompiled x11vnc binary for my Operating
-   System?
-
-   Hopefully the build steps above and FAQ provide enough info for a
-   painless compile for most environments. Please report problems with
-   the x11vnc configure, make, etc. on your system (if your system is
-   known to compile other GNU packages successfully.)
-
-   There are precompiled x11vnc binaries built by other groups that are
-   available at the following locations:
-    Slackware:      (.tgz)  http://www.linuxpackages.net/
-
-   SuSE: (.rpm) http:/software.opensuse.org/ Gentoo: (info)
-   http://gentoo-wiki.com/ and http://gentoo-portage.com/ FreeBSD: (.tbz)
-   http://www.freebsd.org/ http://www.freshports.org/net/x11vnc NetBSD:
-   (src) http://pkgsrc.se/x11/x11vnc OpenBSD: (.tgz) http://openports.se/
-   Arch Linux: (.tgz) http://www.archlinux.org/ Nokia 770 (.deb)
-   http://mike.saunby.googlepages.com/x11vncfornokia7702 Sharp Zaurus
-   http://www.focv.com/ Debian: (.deb) http://packages.debian.org/x11vnc
-   Redhat/Fedora: (.rpm) http://packages.sw.be/x11vnc RPMforge
-   http://dag.wieers.com/rpm/packages/x11vnc/ (N.B.: unmaintained after
-   0.9.3) Solaris: (pkg) http://www.sunfreeware.com/
-
-   If the above binaries don't work and building x11vnc on your OS fails
-   (and all else fails!) you can try one of My Collection of x11vnc
-   Binaries for various OS's and x11vnc releases.
-
-   As a general note, the x11vnc program is simple enough you don't
-   really need to install a package: the binary will in most cases work
-   as is and from any location (as long as your system libraries are not
-   too old, etc.) So, for Linux distributions that are not one of the
-   above, the x11vnc binary from the above packages has a good chance of
-   working. You can "install" it by just copying the x11vnc binary to the
-   desired directory in your PATH. Tip on extracting files from a Debian
-   package: extract the archive via a command like: "ar x
-   x11vnc_0.6-2_i386.deb" and then you can find the binary in the
-   resulting data.tar.gz tar file. Also, rpm2cpio(1) is useful in
-   extracting files from rpm packages.
-
-   If you use a standalone binary like this and also want x11vnc to serve
-   up the Java VNC Viewer jar file (either SSL enabled or regular one),
-   then you will need to extract the classes subdirectory from the source
-   tarball and point x11vnc to it via the -httpdir option. E.g.:
-    x11vnc -httpdir /path/to/x11vnc-0.9.9/classes/ssl ...
-
-
-   Q-6: Where can I get a VNC Viewer binary (or source code) for the
-   Operating System I will be viewing from?
-
-   To obtain VNC viewers for the viewing side (Windows, Mac OS, or Unix)
-   try here:
-     * http://www.tightvnc.com/download.html
-     * http://www.realvnc.com/download-free.html
-     * http://sourceforge.net/projects/cotvnc/
-     * http://www.ultravnc.com/
-     * Our Enhanced TightVNC Viewer (SSVNC)
-
-       [ssvnc.gif]
-
-
-   Q-7: How can I see all of x11vnc's command line options and
-   documentation on how to use them?
-
-   Run:  x11vnc -opts   to list just the option names or run:  x11vnc
-   -help   for long descriptions about each option. The output is listed
-   here as well. Yes, x11vnc does have a lot of options, doesn't it...
-
-
-   Q-8: I don't like typing arcane command line options every time I
-   start x11vnc. What can I do? Is there a config file? Or a GUI?
-
-   You could create a shell script that calls x11vnc with your options:
-#!/bin/sh
-#
-# filename: X11vnc  (i.e. not "x11vnc")
-# It resides in a directory in $PATH. "chmod 755 X11vnc" has been run on it.
-#
-x11vnc -wait 50 -localhost -rfbauth $HOME/.vnc/passwd -display :0 $*
-
-   a similar thing can be done via aliases in your shell (bash, tcsh,
-   csh, etc..)
-
-   Or as of Jun/2004 you can use the simple $HOME/.x11vncrc config file
-   support. If that file exists, each line is taken as a command line
-   option. E.g. the above would be:
-# this is a comment in my ~/.x11vncrc file
-wait 50        # this is a comment to the end of the line.
--localhost     # note: the leading "-" is optional.
-rfbauth  /home/fred/.vnc/passwd
-display :0
-
-   As of Dec/2004 there is now a simple Tcl/Tk GUI based on the
-   remote-control functionality ("-R") that was added. The /usr/bin/wish
-   program is needed for operation. The gui is not particularly
-   user-friendly, it just provides a point and click mode to set all the
-   many x11vnc parameters and obtain help on them. It is also very useful
-   for testing. See the -gui option for more info. Examples: "x11vnc ...
-   -gui" and "x11vnc ... -gui other:0" in the latter case the gui is
-   displayed on other:0, not the X display x11vnc is polling. There is
-   also a "-gui tray" system tray mode.
-
-   [tkx11vnc.gif]
-
-   NOTE: You may need to install the "wish" or "tk" or "tk8.4" package
-   for the gui mode to work (the package name depends on your OS/distro.)
-   The tcl/tk "wish" interpreter is used. In debian (and so ubuntu too)
-   one would run "apt-get install tk" or perhaps "apt-get install tk8.4"
-
-
-   Q-9: How can I get the GUI to run in the System Tray, or at least be a
-   smaller, simpler icon?
-
-   As of Jul/2005 the gui can run in a more friendly small icon mode
-   "-gui icon" or in the system tray: "-gui tray". It has balloon status,
-   a simple menu, and a Properities dialog. The full, complicated, gui is
-   only available under "Advanced". Other improvements were added as
-   well. Try "Misc -> simple_gui" for a gui with fewer esoteric menu
-   items.
-
-   If the gui fails to embed itself in the system tray, do a retry via
-   "Window View -> icon" followed by "Window View -> tray" with the popup
-   menu.
-
-   For inexperienced users starting up x11vnc and the GUI while sitting
-   at the physical X display (not remotely), using something like "x11vnc
-   -display :0 -gui tray=setpass" might be something for them that they
-   are accustomed to in a Desktop environment (it prompts for an initial
-   password, etc.) This is a basic "Share My Desktop" usage mode.
-
-   As of Nov/2008 in x11vnc 0.9.6 there is a desktop menu item
-   (x11vnc.desktop) that runs this command:
-   x11vnc -gui tray=setpass -rfbport PROMPT -logfile %HOME/.x11vnc.log.%VNCDISP
-LAY
-
-   which also prompts for which VNC port to use and a couple other
-   parameters.
-
-
-   Q-10: How can I get x11vnc to listen on a different port besides the
-   default VNC port (5900)?
-
-   Use something like, e.g., "x11vnc -rfbport 5901" to force it to use
-   port 5901 (this is VNC display :1.) If something else is using that
-   port x11vnc will exit immediately. If you do not supply the -rfbport
-   option, it will autoprobe starting at 5900 and work its way up to 5999
-   looking for a free port to listen on. In that case, watch for the
-   PORT=59xx line to see which port it found, then subtract 5900 from it
-   for the VNC display number to enter into the VNC Viewer(s).
-
-   The "-N" option will try to match the VNC display number to the X
-   display (e.g. X11 DISPLAY of :5 (port 6005) will have VNC display :5
-   (port 5905).)
-
-   Also see the "-autoport n" option to indicated at which value the auto
-   probing should start at.
-
-
-   Q-11: My Firewall/Router doesn't allow VNC Viewers to connect to
-   x11vnc.
-
-   See the Firewalls/Routers discussion.
-
-
-   Q-12: Is it possible for a VNC Viewer and a VNC Server to connect to
-   each other even though both are behind Firewalls that block all
-   incoming connections?
-
-   This is very difficult or impossible to do unless a third machine,
-   reachable by both, is used as a relay. So we assume a third machine is
-   somehow being used as a relay.
-
-   (Update: It may be possible to do "NAT-2-NAT" without a relay machine
-   by using a UDP tunnel such as http://samy.pl/pwnat/. All that is
-   required is that both NAT firewalls allow in UDP packets from an IP
-   address to which a UDP packet has recently been sent to. If you try it
-   out let us know how it went.)
-
-   In the following discussion, we will suppose port 5950 is being used
-   on the relay machine as the VNC port for the rendezvous.
-
-   A way to rendezvous is to have the VNC Server start a reverse
-   connection to the relay machine:
-   x11vnc -connect third-machine.net:5950 ...
-
-   and the VNC viewer forward connects as usual:
-   vncviewer third-machine.net:50
-
-   Or maybe two ports would be involved, e.g. the viewer goes to display
-   :51 (5951.) It depends on the relay software being used.
-
-   What software to run on third-machine? A TCP relay of some sort could
-   be used... Try a google search on "tcp relay" or "ip relay". However,
-   note that this isn't a simple redirection because it hooks up two
-   incoming connections. You can look at our UltraVNC repeater
-   implementation ultravnc_repeater.pl for ideas and possibly to
-   customize.
-
-   Also, if you are not the admin of third-machine you'd have to convince
-   the owner to allow you to install this software (and he would likely
-   need to open his server's firewall to allow the port through.)
-
-   It is recommended that SSL is used for encryption (e.g. "-ssl SAVE")
-   when going over the internet.
-
-   We have a prototype for performing a rendezvous via a Web Server
-   acting as the relay machine. Download the vncxfer CGI script and see
-   the instructions at the top.
-
-   Once that CGI script is set up on the website, both users go to, say,
-   http://somesite.com/vncxfer (or maybe a "/cgi-bin" directory or ".cgi"
-   suffix must be used.) Previously, both have agreed on the same session
-   name (say by phone or email) , e.g. "5cows", and put that into the
-   entry form on the vncxfer starting page (hopefully separated by a few
-   seconds, so the relay helper can fully start up at the first request.)
-
-   The page returned tells them the hostname and port number and possible
-   command to use for forward (VNC Viewer) and reverse (VNC Server, i.e.
-   x11vnc) connections as described above.
-
-   Also since Oct/2007, x11vnc can connect directly (no web browser),
-   like this:
-   x11vnc ... -connect localhost:0 -proxy 'http://somesite.com/vncxfer?session=
-5cows&'
-
-   Unfortunately the prototype requires that the Web server's firewall
-   allow in the port (e.g. 5950) used for the rendezvous. Most web
-   servers are not configured to do this, so you would need to ask the
-   admin to do this for you. Nearly all free webspace sites, e.g.
-   www.zendurl.com, will not allow your CGI script to be an open relay
-   like this. (If you find one that does allow this, let me know!)
-
-   Maybe someday a clever trick will be thought up to relax the listening
-   port requirement (e.g. use HTTP/CGI itself for the transfer... it is
-   difficult to emulate a full-duplex TCP connection with them.)
-
-   See also the Firewalls/Routers discussion and Reverse Connection Proxy
-   discussion.
-
-
-   SSH method: If both users (i.e. one on Viewer-side and the other on
-   x11vnc server side) have SSH access to a common machine on the
-   internet (or otherwise mutually reachable), then SSH plumbing can be
-   used to solve this problem. The users create SSH tunnels going through
-   the SSH login machine.
-
-   Instead of assuming port 5900 is free on the SSH machine, we will
-   assume both users agreed to use 5933. This will illustrate how to use
-   a different port for the redir. It could be any port, what matters is
-   that both parties refer to the same one.
-
-   Set up the Tunnel from the VNC Server side:
-   ssh -t -R 5933:localhost:5900 user@third-machine.net
-
-   Set up the Tunnel from the VNC Viewer side:
-   ssh -t -L 5900:localhost:5933 user@third-machine.net
-
-   Run Server on the VNC Server side:
-   x11vnc -rfbport 5900 -localhost ...
-
-   Run Viewer on the VNC Viewer side:
-   vncviewer -encodings "copyrect tight zrle hextile" localhost:0
-
-   (we assume the old-style -encodings option needs to be used. See here
-   for details.)
-
-   If the SSH machine has been configured (see sshd_config(5)) with the
-   option GatewayPorts=yes, then the tunnel set up by the VNC Server will
-   be reachable directly by the VNC viewer (as long as the SSH machine's
-   firewall does not block the port, 5933 in this example.) So in that
-   case the Viewer side does not need to run any ssh command, but rather
-   only runs:
-   vncviewer third-machine.net:33
-
-   In this case we recommend SSL be used for encryption.
-
-   The creation of both tunnels can be automated. As of Oct/2007 the -ssh
-   x11vnc option is available and so only this command needs to be run on
-   the VNC Server side:
-   x11vnc -ssh user@third-machine.net:33 ...
-
-   (the SSH passphrase may need to be supplied.)
-
-   To automate on the VNC Viewer side, the user can use the Enhanced
-   TightVNC Viewer (SSVNC) by:
-     * Clicking on 'Use SSH'
-     * Entering user@third-machine.net:33 into 'VNC Host:Display' entry
-       box
-     * Clicking on 'Connect'
-
-   As above, if the SSH GatewayPorts=yes setting is configured the Viewer
-   side doesn't need to create a SSH tunnel. In SSVNC the Viewer user
-   could instead select 'Use SSL' and then, e.g., on the Server side
-   supply "-ssl SAVE" to x11vnc. Then end-to-end SSL encryption would be
-   used (in addition to the SSH encryption on the Server-side leg.)
-
-
-   Q-13: Can I make x11vnc more quiet and also go into the background
-   after starting up?
-
-   Use the -q and -bg options, respectively.  (also: -quiet is an alias
-   for -q)
-
-   Note that under -bg the stderr messages will be lost unless you use
-   the "-o logfile" option.
-
-
-   Q-14: Sometimes when a VNC viewer dies abruptly, x11vnc also dies with
-   the error message like: "Broken pipe". I'm using the -forever mode and
-   I want x11vnc to keep running.
-
-   As of Jan/2004 the SIGPIPE signal is ignored. So if a viewer client
-   terminates abruptly, libvncserver will notice on the next I/O
-   operation and will close the connection and continue on.
-
-   Up until of Apr/2004 the above fix only works for BSD signal systems
-   (Linux, FreeBSD, ...) For SYSV systems there is a workaround in place
-   since about Jun/2004.
-
-
-   Q-15: The Windows TightVNC 1.3.9 Viewer cannot connect to x11vnc.
-
-   This appears to be fixed in x11vnc version 0.9 and later. If you need
-   to use an earlier version of x11vnc, try using the "-rfbversion 3.7"
-   option. In general sometimes one can get a misbehaving viewer to work
-   by supplying rfb versions 3.7 or 3.3.
-
-
-   Q-16: KDE's krdc VNC viewer cannot connect to x11vnc.
-
-   This has been fixed in x11vnc version 0.8.4. More info here, here, and
-   here.
-
-
-   Q-17: When I start x11vnc on an Alpha Tru64 workstation the X server
-   crashes!
-
-   This is a bug in the X server obviously; an X client should never be
-   able to crash it.
-
-   The problem seems to be with the RECORD X extension and so a
-   workaround is to use the "-noxrecord" x11vnc command line option.
-
-
-   Q-18: When running x11vnc on an IBM AIX workstation after a few
-   minutes the VNC connection freezes.
-
-   One user reports when running x11vnc on AIX 5.3 in his CDE session
-   after a few minutes or seconds x11vnc will "freeze" (no more updates
-   being sent, etc.) The freezing appeared to be worse for versions later
-   than 0.9.2.
-
-   The problem seems to be with the RECORD X extension on AIX and so a
-   workaround is to use the "-noxrecord" x11vnc command line option. The
-   user found no freezes occurred when using that option.
-
-
-   Q-19: Are there any build-time customizations possible, e.g. change
-   defaults, create a smaller binary, etc?
-
-   There are some options. They are enabled by adding something like

-/*
- * Mar/2006
- * Build-time customization via CPPFLAGS.
- *
- * Summary of options to include in CPPFLAGS for custom builds:
- *
- * -DVNCSHARED  to have the vnc display shared by default.
- * -DFOREVER  to have -forever on by default.
- * -DNOREPEAT=0  to have -repeat on by default.
- * -DADDKEYSYMS=0  to have -noadd_keysyms the default.
- *
- * -DREMOTE_DEFAULT=0  to disable remote-control on by default (-yesremote.)
- * -DREMOTE_CONTROL=0  to disable remote-control mechanism completely.
- * -DEXTERNAL_COMMANDS=0  to disable the running of all external commands.
- * -DFILEXFER=0  disable filexfer.
- *
- * -DHARDWIRE_PASSWD=...      hardwired passwords, quoting necessary.
- * -DHARDWIRE_VIEWPASSWD=...
- * -DNOPW=1                   make -nopw the default (skip warning)
- * -DUSEPW=1                  make -usepw the default

- * -DPOLL_8TO24_DELAY=N
- * -DDEBUG_XEVENTS=1  enable printout for X events.
- *
- * Set these in CPPFLAGS before running configure. E.g.:
- *
- *   % env CPPFLAGS="-DFOREVER -DREMOTE_CONTROL=0" ./configure
- *   % make
- */
-
-   If other things (e.g. "-I ...") are needed in CPPFLAGS add them as
-   well.
-
-   On some systems is seems you need to set LC_ALL=C for configure to
-   work properly...
-
-   Be careful the following two variables: HARDWIRE_PASSWD and
-   HARDWIRE_VIEWPASSWD. If set (remember to include the double quotes
-   around the string), they will be used as default values for the
-   -passwd and -viewpasswd options. Of course the strings will exist
-   unobscured in the x11vnc binary: it better not be readable by
-   unintendeds. Perhaps this is of use in remote access for an embedded
-   application, etc...
-
-   Let us know if more build-time customizations would be useful.

-   [Win2VNC Related]
-
-   Q-20: I have two separate machine displays in front of me, one Windows
-   the other X11: can I use x11vnc in combination with Win2VNC in
-   dual-screen mode to pass the keystrokes and mouse motions to the X11
-   display?
-
-   Yes, for best response start up x11vnc with the "-nofb" option
-   (disables framebuffer polling, and does other optimizations) on the
-   secondary display (X11) machine. Then start up Win2VNC on the primary
-   display (Windows) referring it to the secondary display.
-
-   This will also work X11 to X11 using x2vnc, however you would probably
-   just want to avoid VNC and use x2x for that.
-
-   For reference, here are some links to Win2VNC-like programs for
-   multiple monitor setups:
-     * Original Win2VNC
-     * Enhanced Win2VNC (broken?) and sourceforge link
-     * x2vnc
-     * x2x
-     * zvnc (MorphOS)
-
-   All of them will work with x11vnc (except x2x where it is not needed.)
-
-
-   Q-21: I am running Win2VNC on my Windows machine and "x11vnc -nofb" on
-   Unix to pass keyboard and mouse to the Unix monitor. Whenever I start
-   Win2VNC it quickly disconnects and x11vnc says:
-   rfbProcessClientNormalMessage: read: Connection reset by peer
-
-   Is the default visual of the X display you run x11vnc on low color
-   (e.g. 8 bit per pixel PseudoColor)? (you can run xdpyinfo to check,
-   look in the "screen" section.) There seems to be a bug in Win2VNC in
-   that it cannot deal correctly with colormaps (PseudoColor is the most
-   common example of a visual with a colormap.)
-
-   If so, there are a couple options. 1) Can you set the default visual
-   on your display to be depth 24 TrueColor? Sun machines often have 8+24
-   overlay/multi-depth visuals, and you can make the default visual depth
-   24 TrueColor (see fbconfig(1) and Xsun(1).) 2) As of Feb/2004 x11vnc
-   has the -visual option to allow you to force the framebuffer visual to
-   whatever you want (this usually messes up the colors unless you are
-   very clever.) In this case, the option provides a convenient
-   workaround for the Win2VNC bug:
-  x11vnc -nofb -visual TrueColor -display :0 ...
-
-   So the visual will be set to 8bpp TrueColor and Win2VNC can handle
-   this. Since Win2VNC does not use the framebuffer data there should be
-   no problems in doing this.
-
-   Q-22: Can I run "x11vnc -nofb" on a Mac OS X machine to redirect mouse
-   and keyboard input to it from Windows and X11 machines via Win2VNC and
-   x2vnc, respectively?
-
-   Yes, as of Nov/2006 you can. There may be a trick or two you'll need
-   to do to get the Clipboard exchange between the machines to work.
-
-
-
-   [Color Issues]
-
-   Q-23: The X display I run x11vnc on is only 8 bits per pixel (bpp)
-   PseudoColor (i.e. only 256 distinct colors.) The x11vnc colors may
-   start out OK, but after a while they are incorrect in certain windows.
-
-   Use the -flashcmap option to have x11vnc watch for changes in the
-   colormap, and propagate those changes back to connected clients. This
-   can be slow (since the whole screen must be updated over the network
-   whenever the colormap changes.) This flashing colormap behavior often
-   happens if an application installs its own private colormap when the
-   mouse is in its window. "netscape -install" is a well-known historical
-   example of this. Consider reconfiguring the system to 16 bpp or depth
-   24 TrueColor if at all possible.
-
-   Also note the option -8to24 (Jan/2006) can often remove the need for
-   flashing the colormap. Everything is dynamically transformed to depth
-   24 at 32 bpp using the colormaps. There may be painting errors however
-   (see the following FAQ for tips on reducing and correcting them.)
-
-   In some rare cases (SCO unixware) the -notruecolor option has
-   corrected colors on 8bpp displays. The red, green, and blue masks were
-   non-zero in 8bpp PseudoColor on an obscure setup, and this option
-   corrected the problems.
-
-
-   Q-24: Color problems: Why are the colors for some windows incorrect in
-   x11vnc? BTW, my X display has nice overlay/multi-depth visuals of
-   different color depths: e.g. there are both depth 8 and 24 visuals
-   available at the same time.
-
-   You may want to review the previous question regarding 8 bpp
-   PseudoColor.
-
-   On some hardware (Sun/SPARC and SGI), the -overlay option discussed a
-   couple paragraphs down may solve this for you (you may want to skip to
-   it directly.) On other hardware the less robust -8to24 option may help
-   (also discussed below.)
-
-   Run xdpyinfo(1) to see what the default visual is and what the depths
-   of the other visuals are. Does the default visual have a depth of 8
-   but there are other visuals of depth 24? If it does, can you possibly
-   re-configure your X server to make a depth 24 visual the default? If
-   you can do it, this will save you a lot of grief WRT colors and x11vnc
-   (and for general usage too!) Here is how I do this on an old
-   Sparcstation 20 running Solaris 9 with SX graphics
-  xinit -- -dev /dev/fb defclass TrueColor defdepth 24
-
-   and it works nicely (note: to log into console from the dtlogin
-   window, select "Options -> Command Line Login", then login and enter
-   the above command.) See the -dev section of the Xsun(1) manpage for a
-   description of the above arguments. If you have root permission, a
-   more permanent and convenient thing to do is to record the arguments
-   in a line like:
-  :0  Local local_uid@console root /usr/openwin/bin/Xsun -dev /dev/fb defclass
-TrueColor defdepth 24
-
-   in /etc/dt/config/Xservers (copy /usr/dt/config/Xservers.) Also look
-   at the fbconfig(1) and related manpages (e.g. ffbconfig, m64config,
-   pgxconfig, SUNWjfb_config, etc ...) for hardware framebuffer settings
-   that may achieve the same effect.
-
-   In general for non-Sun machines, look at the "-cc class" and related
-   options in your X server manpage (perhaps Xserver(1)), it may allow
-   modifying the default visual (e.g. "-cc 4", see <X11/X.h> for the
-   visual class numbers.) On XFree86 some video card drivers (e.g. Matrox
-   mga) have settings like Option "Overlay" "24,8" to support multi-depth
-   overlays. For these, use the "-cc 4" X server command line option to
-   get a depth 24 default visual.
-
-
-   The -overlay mode: Another option is if the system with overlay
-   visuals is a Sun system running Solaris or SGI running IRIX you can
-   use the -overlay x11vnc option (Aug/2004) to have x11vnc use the
-   Solaris XReadScreen(3X11) function to poll the "true view" of the
-   whole screen at depth 24 TrueColor. XReadDisplay(3X11) is used on
-   IRIX. This is useful for Legacy applications (older versions of
-   Cadence CAD apps are mentioned by x11vnc users) that require the
-   default depth be 8bpp, or the app will use a 8bpp visual even if depth
-   24 visuals are available, and so the default depth workaround
-   described in the previous paragraph is not sufficient for these apps.
-
-   It seems that Xorg is working toward supporting XReadDisplay(3X11) as
-   part of the RENDER extension work. When it does support it and
-   provides a library API x11vnc will be modified to take advantage of
-   the feature to support -overlay on Linux, *BSD, etc. Until then see
-   the -8to24 mode below.
-
-   Misc. notes on -overlay mode: An amusing by-product of -overlay mode
-   is that the mouse cursor shape is correct! (i.e. XFIXES is not
-   needed.) The -overlay mode may be somewhat slower than normal mode due
-   to the extra framebuffer manipulations that must be performed. Also,
-   on Solaris there is a bug in that for some popup menus, the windows
-   they overlap will have painting errors (flashing colors) while the
-   popup is up (a workaround is to disable SaveUnders by passing -su to
-   Xsun, e.g. in your /etc/dt/config/Xservers file.)
-
-
-   The -8to24 mode: The -8to24 x11vnc option (Jan/2006) is a kludge to
-   try to dynamically rewrite the pixel values so that the 8bpp part of
-   the screen is mapped onto depth 24 TrueColor. This is less robust than
-   the -overlay mode because it is done by x11vnc outside of the X
-   server. So only use it on OS's that do not support -overlay. The
-   -8to24 mode will work if the default visual is depth 24 or depth 8. It
-   scans for any windows within 3 levels of the root window that are 8bpp
-   (i.e. legacy application), or in general ones that are not using the
-   default visual. For the windows it finds it uses XGetSubImage() to
-   retrieve the pixels values and uses the correct indexed colormap to
-   create a depth 24 TrueColor view of the whole screen. This depth 24,
-   32bpp view is exported via VNC.
-
-   Even on pure 8bpp displays it can be used as an alternative to
-   -flashcmap to avoid color flashing completely.
-
-   This scheme is approximate and can often lead to painting errors. You
-   can manually correct most painting errors by pressing 3 Alt_L's in a
-   row, or by using something like: -fixscreen V=3.0 to automatically
-   refresh the screen every 3 seconds. Also -fixscreen 8=3.0 has been
-   added to just refresh the non-default visual parts of the screen.
-
-   In general the scheme uses many resources and may give rise to
-   sluggish behavior. If multiple windows are using different 8bpp
-   indexed colormaps all but one window may need to be iconified for the
-   colors to be correct. There are a number of tunable parameters to try
-   to adjust performance and painting accuracy. The option -8to24
-   nogetimage can give a nice speedup if the default depth 24 X server
-   supports hiding the 8bpp bits in bits 25-32 of the framebuffer data.
-   On very slow machines -8to24 poll=0.2,cachewin=5.0 gives an useful
-   speedup. See the -8to24 help description for information on tunable
-   parameters, etc.
-
-
-   Colors still not working correctly? Run xwininfo on the application
-   with the incorrect colors to verify that the depth of its visual is
-   different from the default visual depth (gotten from xdpyinfo.) One
-   possible workaround in this case is to use the -id option to point
-   x11vnc at the application window itself. If the application is
-   complicated (lots of toplevel windows and popup menus) this may not be
-   acceptable, and may even crash x11vnc (but not the application.) See
-   also -appshare.
-
-   It is theoretically possible to solve this problem in general (see
-   xwd(1) for example), but it does not seem trivial or sufficiently fast
-   for x11vnc to be able to do so in real time. The -8to24 method does
-   this approximately and is somewhat usable. Fortunately the -overlay
-   option works for Solaris machines with overlay visuals where most of
-   this problem occurs.
-
-
-   Q-25: I am on a high color system (depth >= 24) but I seem to have
-   colormap problems. They either flash or everything is very dark.
-
-   This can happen if the default Visual (use xdpyinfo to list them) is
-   DirectColor instead of TrueColor. These are both usually used in high
-   color modes, but whereas TrueColor uses static ramps for the Red,
-   Green, and Blue components, DirectColor has arbitrary colormaps for
-   the Red, Green, and Blue Components. Currently x11vnc cannot decode
-   these colormaps and treats them just like TrueColor.
-
-   The only workaround so far is to restart the X server with the "-cc 4"
-   option to force TrueColor as the default visual (DirectColor is "-cc
-   5"; see /usr/include/X11/X.h.) The only place we have seen this is
-   with the virtual framebuffer server Xvfb on Xorg 7.2. So in that case
-   you probably should restart it with something like this: "Xvfb :1 -cc
-   4 -screen 0 1280x1024x24". It should be possible for x11vnc to handle
-   DirectColor, but this hasn't been implemented due to its rare usage.
-
-   You may also see this problem on an X display with a TrueColor default
-   visual where an application chooses a DirectColor visual for its
-   window(s). It seems the application also needs to install its own
-   colormap for the visual for the colors to be messed up in x11vnc. One
-   can make xwud do this for example.
-
-
-   Q-26: How do I figure out the window id to supply to the -id windowid
-   option?
-
-   Run the xwininfo program in a terminal. It will ask you to click on
-   the desired application window. After clicking, it will print out much
-   information, including the window id (e.g. 0x6000010.) Also, the
-   visual and depth of the window printed out is often useful in
-   debugging x11vnc color problems.
-
-   Also, as of Dec/2004 you can use "-id pick" to have x11vnc run
-   xwininfo(1) for you and after you click the window it extracts the
-   windowid. Besides "pick" there is also "id:root" to allow you to go
-   back to root window when doing remote-control.
-
-
-   Q-27: Why don't menus or other transient windows come up when I am
-   using the -id windowid option to view a single application window?
-
-   This is related to the behavior of the XGetImage(3X11) and
-   XShmGetImage() interfaces regarding backingstore, saveunders, etc. The
-   way the image is retrieved depends on some aspects of how the X server
-   maintains the display image data and whether other windows are
-   clipping or obscuring it. See the XGetImage(3X11) man page for more
-   details. If you disable BackingStore and SaveUnders in the X server
-   you should be able to see these transient windows.
-
-   If things are not working and you still want to do the single window
-   polling, try the -sid windowid option ("shifted" windowid.)
-
-   Update: as of Nov/2009 in the 0.9.9 x11vnc development tarball, there
-   is an experimental Application Sharing mode that improves upon the
-   -id/-sid single window sharing: -appshare (run "x11vnc -appshare
-   -help" for more info.) It is still very primitive and approximate, but
-   at least it displays multiple top-level windows.
-
-
-   Q-28: My X display is depth 24 at 24bpp (instead of the normal depth
-   24 at 32bpp.) I'm having lots of color and visual problems with x11vnc
-   and/or vncviewer. What's up?
-
-   First off, depth 24 at 24bpp (bpp=bits-per-pixel) is fairly uncommon
-   and can cause problems in general. It also can be slower than depth 24
-   at 32bpp. You might want to switch to 32bpp (for XFree86 see the
-   "-fbbpp 32", DefaultFbBpp, FbBpp and related options.) Perhaps you
-   have 24bpp because the video memory of the machine is low and the
-   screen wouldn't fit in video RAM at 32bpp. For this case depth 16 at
-   16bpp might be an acceptable option.
-
-   In any event x11vnc should handle depth 24 at 24bpp (although
-   performance may be slower, and you may need to use the ZRLE encoding
-   instead of Tight.) There are some caveats involving the viewer
-   however:
-
-   The RealVNC Unix viewer cannot handle 24bpp from the server, it will
-   say: "main: setPF: not 8, 16 or 32 bpp?" and exit. I have not checked
-   the RealVNC Windows viewer.
-
-   So you need to use the TightVNC Unix viewer. However there are some
-   problems with that too. It seems libvncserver does not do 24bpp
-   correctly with the Tight encoding. The colors and screen ultimately
-   get messed up. So you have to use a different encoding with the
-   TightVNC vncviewer, try "zlib", "hextile", or one of the other
-   encodings (e.g. vncviewer -encodings "zlib hextile" ....) I have not
-   checked the TightVNC or UltraVNC Windows viewers.
-
-   It appears the older RealVNC Unix viewers (e.g. 3.3.3 and 3.3.7) can
-   handle 24bpp from the server, so you may want to use those. They
-   evidently request 32 bpp and libvncserver obliges.
-
-   Update: as of Apr/2006 you can use the -24to32 option to have x11vnc
-   dynamically transform the 24bpp pixel data to 32bpp. This extra
-   transformation could slow things down further however.
-
-   Now coming the opposite direction if you are running the vncviewer on
-   the 24bpp display, TightVNC will fail with "Can't cope with 24
-   bits-per-pixel. Sorry." and RealVNC will fail with "main: Error:
-   couldn't find suitable pixmap format" so evidently you cannot use
-   24bpp for the vncviewers to work on that X display.
-
-   Note, however, that the Unix viewer in the Enhanced TightVNC Viewer
-   (SSVNC) project can handle 24bpp X displays. It does this by
-   requesting a 16bpp pixel format (or 8bpp if the -bgr233 option has
-   been supplied) from the VNC server, and translates that to 24bpp
-   locally.
-   [Xterminals]
-
-   Q-29: Can I use x11vnc to view and interact with an Xterminal (e.g.
-   NCD) that is not running UNIX and so x11vnc cannot be run on it
-   directly?
-
-   You can, but it will likely be very wasteful of network bandwidth
-   since you will be polling the X display over the network as opposed to
-   over the local hardware. To do this, run x11vnc on a UNIX machine as
-   close as possible network-wise (e.g. same switch) to the Xterminal
-   machine. Use the -display option to point the display to that of the
-   Xterminal (you'll of course need basic X11 permission to do that) and
-   finally supply the -noshm option (this enables the polling over the
-   network.)
-
-   If the Xterminal's X display is open to the network for connections,
-   you might use something like "-display xterm123:0". If you are trying
-   to do this via an SSH tunnel (assuming you can actually ssh into the
-   Xterminal) it will be a little tricky (either use the ssh "-R" option
-   or consider ssh-ing in the other direction.) In all cases the X11
-   permissions need to allow the connection.
-
-   The response will likely be sluggish (maybe only one "frame" per
-   second.) This mode is not recommended except for "quick checks" of
-   hard to get to X servers. Use something like "-wait 150" to cut down
-   on the polling rate. You may also need -flipbyteorder if the colors
-   get messed up due to endian byte order differences.
-
-   Q-30: How do I get my X permissions (MIT-MAGIC-COOKIE file) correct
-   for a Unix/Linux machine acting as an Xterminal?
-
-   If the X display machine is a traditional Xterminal (where the X
-   server process runs on the Xterminal box, but all of the X client
-   applications (firefox, etc) run on a central server (aka "terminal
-   server")), you will need to log into the Xterminal machine (i.e. get a
-   shell running there) and then start the x11vnc program. If the
-   Xterminal Linux/Unix machine is stripped down (e.g. no users besides
-   root) that may be difficult.
-
-   The next problem is the login Display Manager (e.g. gdm, kdm), and
-   hence the MIT-MAGIC-COOKIE auth files, are on the central server and
-   not on the Xterminal box where the X server and x11vnc processes are.
-
-   So unless X permissions are completely turned off (e.g. "xhost +"), to
-   run the x11vnc process on the Xterminal box the MIT-MAGIC-COOKIE auth
-   file data (XAUTHORITY or $HOME/.Xauthority) must be accessible by or
-   copied to the Xterminal. If $HOME/.Xauthority is exported via NFS
-   (this is insecure of course, but has been going on for decades), then
-   x11vnc can simply pick it up via NFS (you may need to use the -auth
-   option to point to the correct file.) Other options include copying
-   the auth file using scp, or something like:
-  central-server>  xauth nextract - xterm123:0 | ssh xterm123 xauth nmerge -
-
-   and then, say, ssh from central-server to xterm123 to start x11vnc.
-   Here "xterm123" refers to the computer acting as the Xterminal and
-   "central-server" is the terminal server. You can use "xauth -f
-   /path/to/cookie-file list" to examine the contents of the cookie(s) in
-   a file "/path/to/cookie-file". See the xauth(1) manpage for more
-   details.
-
-   If the display name in the cookie file needs to be changed between the
-   two hosts, see this note on the "xauth add ..." command.
-
-   A less secure option is to run something like "xhost +127.0.0.1" while
-   sitting at the Xterminal box to allow cookie-free local access for
-   x11vnc. You can run "xhost -127.0.0.1" after x11vnc connects if you
-   want to go back to the original permissions.
-
-   If the Xterminal is really stripped down and doesn't have any user
-   accounts, NFS, etc. you'll need to contact your system administrator
-   to set something up. It can be done!!!  Some Xterminal projects have
-   actually enabled "run locally" facilities for the running of an
-   occasional app more efficiently locally on the Xterminal box (e.g.
-   realplayer.)
-
-   Not recommended, but as a last resort, you could have x11vnc poll the
-   Xterminal Display over the network. For this you would run a "x11vnc
-   -noshm ..." process on the central-server (and hope the network admin
-   doesn't get angry...)
-
-   Note: use of Display Manager (gdm, kdm, ...) auth cookie files (i.e.
-   from /var/...,  /tmp/..., or elsewhere) may require modification via
-   xauth(1) to correctly include the display x11vnc refers to (e.g.
-   "xauth -f cookie-file add :0 . 45be51ae2ce9dfbacd882ab3ef8e96b1",

-   VNCviewer performance on Xterminals:  This isn't related to x11vnc on
-   Xterminals, but we mention it here anyway because of the similar
-   issues. If you are on an Xterminal and want to use vncviewer to
-   connect to a VNC server somewhere, then performance would be best if
-   you ran the viewer on the Xterminal box. Otherwise, (i.e. running the
-   viewer process on the central-server) all of the vncviewer screen
-   drawing is done more inefficiently over the network. Something to
-   consider, especially on a busy network. (BTW, this has all of the
-   above permission, etc, problems: both vncviewer and x11vnc are X
-   client apps desired to be run on the Xterminal box.)
-
-   [Sun Rays]
-
-   Q-31: I'm having trouble using x11vnc with my Sun Ray session.
-
-   The Sun Ray technology is a bit like "VNC done in hardware" (the Sun
-   Ray terminal device, DTU, playing the role of the vncviewer.)
-   Completely independent of that, the SunRay user's session is still an
-   X server that speaks the X11 protocol and so x11vnc simply talks to
-   the X server part to export the SunRay desktop to any place in the
-   world (i.e. not only to a Sun Ray terminal device), creating a sort of
-   "Soft Ray". Please see this discussion of Sun Ray issues for solutions
-   to problems.
-
-   Also see the Sun Ray Remote Control Toolkit that uses x11vnc.
-
-   [Remote Control]
-
-   Q-32: How do I stop x11vnc once it is running in the background?
-
-   As of Dec/2004 there is a remote control feature. It can change a huge
-   number of parameters on the fly: see the -remote and -query options.
-   To shut down the running x11vnc server just type "x11vnc -R stop". To
-   disconnect all clients do "x11vnc -R disconnect:all", etc.
-
-   If the -forever option has not been supplied, x11vnc will
-   automatically exit after the first client disconnects. In general if
-   you cannot use the remote control, then you will have to kill the
-   x11vnc process This can be done via: "kill NNNNN" (where NNNNN is the
-   x11vnc process id number found from ps(1)), or "pkill x11vnc", or
-   "killall x11vnc" (Linux only.)
-
-   If you have not put x11vnc in the background via the -bg option or
-   shell & operator, then simply press Ctrl-C in the shell where x11vnc
-   is running to stop it.
-
-   Potential Gotcha: If somehow your Keypress of Ctrl-C went through
-   x11vnc to the Xserver that then delivered it to x11vnc it is possible
-   one or both of the Ctrl or C keys will be left stuck in the pressed
-   down state in the Xserver. Tapping the stuck key (either via a new
-   x11vnc or at the physical console) will release it from the stuck
-   state. If the keyboard seems to be acting strangely it is often fixed
-   by tapping Ctrl, Shift, and Alt. Alternatively, the -clear_mods option
-   and -clear_keys option can be used to release pressed keys at startup
-   and exit. The option -clear_all will also try to unset Caps_Lock,
-   Num_Lock, etc.
-
-
-   Q-33: Can I change settings in x11vnc without having to restart it?
-   Can I remote control it?
-
-   Look at the -remote (an alias is -R) and -query (an alias is -Q)
-   options added in Dec/2004. They allow nearly everything to be changed
-   dynamically and settings to be queried. Examples: "x11vnc -R shared",
-   "x11vnc -R forever", "x11vnc -R scale:3/4", "x11vnc -Q modtweak",
-   "x11vnc -R stop", "x11vnc -R disconnect:all", etc..
-
-   These commands do not start a x11vnc server, but rather communicate
-   with one that is already running. The X display (X11VNC_REMOTE
-   property) is used as the communication channel, so the X permissions
-   and DISPLAY must be set up correctly for communication to be possible.
-
-   There is also a simple Tcl/Tk gui based on this remote control
-   mechanism. See the -gui option for more info. You will need to have
-   Tcl/Tk (i.e. /usr/bin/wish) installed for it to work. It can also run
-   in the system tray: "-gui tray" or as a standalone small icon window:
-   "-gui icon". Use "-gui tray=setpass" for a naive user "Share My
-   Desktop" mode.
-
-   [Security and Permissions]
-
-   Q-34: How do I create a VNC password for use with x11vnc?
-
-   You may already have one in $HOME/.vnc/passwd if you have used, say,
-   the vncserver program from the regular RealVNC or TightVNC packages
-   (i.e. launching the Xvnc server.) Otherwise, you could use the
-   vncpasswd(1) program from those packages.
-
-   As of Jun/2004 x11vnc supports the -storepasswd "pass" "file" option,
-   which is the same functionality of storepasswd. Be sure to quote the
-   "pass" if it contains shell meta characters, spaces, etc. Example:
-  x11vnc -storepasswd 'sword*fish' $HOME/myvncpasswd
-
-   You then use the password via the x11vnc option: "-rfbauth
-   $HOME/myvncpasswd"
-
-   As of Jan/2006 if you do not supply any arguments:
-  x11vnc -storepasswd
-
-   you will be prompted for a password to save to ~/.vnc/passwd (your
-   keystrokes when entering the password will not be echoed to the
-   screen.) If you supply one argument, e.g. "x11vnc -storepasswd
-   ~/.mypass", the password you are prompted for will be stored in that
-   file.
-
-   x11vnc also has the -passwdfile and -passwd/-viewpasswd plain text
-   (i.e. not obscured like the -rfbauth VNC passwords) password options.
-
-   You can use the -usepw option to automatically use any password file
-   you have in ~/.vnc/passwd or ~/.vnc/passwdfile (the latter is used
-   with the -passwdfile option.)
-
-  x11vnc -usepw -display :0 ...
-
-   If neither file exists you are prompted to store a password in
-   ~/.vnc/passwd. If a password file cannot be found or created x11vnc
-   exits immediately. An admin may want to set it up this way for users
-   who do not know better.
-
-
-   Q-35: Can I make it so -storepasswd doesn't show my password on the
-   screen?
-
-   You can use the vncpasswd program from RealVNC or TightVNC mentioned
-   above. As of Jan/2006 the -storepasswd option without any arguments
-   will not echo your password as you type it and save the file to
-   ~/.vnc/passwd:
-  # x11vnc -storepasswd
-  Enter VNC password:
-  Verify password:
-  Write password to /home/myname/.vnc/passwd?  [y]/n
-  Password written to: /home/myname/.vnc/passwd
-
-   You can also give it an alternate filename, e.g. "x11vnc -storepasswd
-   ~/.mypass"
-
-
-   Q-36: Can I have two passwords for VNC viewers, one for full access
-   and the other for view-only access to the display?
-
-   Yes, as of May/2004 there is the -viewpasswd option to supply the
-   view-only password. Note the full-access password option -passwd must
-   be supplied at the same time. E.g.: -passwd sword -viewpasswd fish.
-
-   To avoid specifying the passwords on the command line (where they
-   could be observed via the ps(1) command by any user) you can use the
-   -passwdfile option to specify a file containing plain text passwords.
-   Presumably this file is readable only by you, and ideally it is
-   located on the machine x11vnc is run on (to avoid being snooped on
-   over the network.) The first line of this file is the full-access
-   password. If there is a second line in the file and it is non-blank,
-   it is taken as the view-only password. (use "__EMPTY__" to supply an
-   empty one.)
-
-   View-only passwords currently do not work for the -rfbauth password
-   option (standard VNC password storing mechanism.) FWIW, note that
-   although the output (usually placed in $HOME/.vnc/passwd) by the
-   vncpasswd or storepasswd programs (or from x11vnc -storepasswd) looks
-   encrypted they are really just obscured to avoid "casual" password
-   stealing. It takes almost no skill to figure out how to extract the
-   plain text passwords from $HOME/.vnc/passwd since it is very
-   straight-forward to work out what to do from the VNC source code.
-
-
-   Q-37: Can I have as many full-access and view-only passwords as I
-   like?
-
-   Yes, as of Jan/2006 in the libvncserver CVS the -passwdfile option has
-   been extended to handle as many passwords as you like. You put the
-   view-only passwords after a line __BEGIN_VIEWONLY__.
-
-   You can also easily annotate and comment out passwords in the file.
-   You can have x11vnc re-read the file dynamically when it is modified.
-
-
-   Q-38: Does x11vnc support Unix usernames and passwords? Can I further
-   limit the set of Unix usernames who can connect to the VNC desktop?
-   Update: as of Feb/2006 x11vnc has the -unixpw option that does this
-   outside of the VNC protocol and libvncserver. The standard su(1)
-   program is used to validate the user's password. A familiar "login:"
-   and "Password:" dialog is presented to the user on a black screen
-   inside the vncviewer. The connection is dropped if the user fails to
-   supply the correct password in 3 tries or does not send one before a
-   25 second timeout. Existing clients are view-only during this period.
-   A list of allowed Unix usernames may also be supplied along with
-   per-user settings.
-
-   There is also the -unixpw_nis option for non-shadow-password
-   (typically NIS environments, hence the name) systems where the
-   traditional getpwnam() and crypt() functions are used instead of
-   su(1). The encrypted user passwords must be accessible to the user
-   running x11vnc in -unixpw_nis mode, otherwise the logins will always
-   fail even when the correct password is supplied. See ypcat(1) and
-   shadow(5).
-
-   Two settings are enforced in the -unixpw and -unixpw_nis modes to
-   provide extra security: the 1) -localhost and 2) -stunnel or -ssl
-   options. Without these one might send the Unix username and password
-   data in clear text over the network which is a very bad idea. They can
-   be relaxed if you want to provide encryption other than stunnel or
-   -ssl (the constraint is automatically relaxed if SSH_CONNECTION is set
-   and indicates you have ssh-ed in, however the -localhost requirement
-   is still enforced.)
-
-   The two -unixpw modes have been tested on Linux, Solaris, Mac OS X,
-   HP-UX, AIX, Tru64, FreeBSD, OpenBSD, and NetBSD. Additional testing is
-   appreciated. For the last 4 it appears that su(1) will not prompt for
-   a password if su-ing to oneself. Since x11vnc requires a password
-   prompt from su, x11vnc forces those logins to fail even when the
-   correct password is supplied. On *BSD it appears this can be corrected
-   by removing the pam_self.so entry in /etc/pam.d/su.
-
-
-   Previous older discussion (prior to the -unixpw option):
-
-   Until the VNC protocol and libvncserver support this things will be
-   approximate at best.
-
-   One approximate method involves starting x11vnc with the -localhost
-   option. This basically requires the viewer user to log into the
-   workstation where x11vnc is running via their Unix username and
-   password, and then somehow set up a port redirection of his vncviewer
-   connection to make it appear to emanate from the local machine. As
-   discussed above, ssh is useful for this: "ssh -L 5900:localhost:5900
-   user@hostname ..." See the ssh wrapper scripts mentioned elsewhere on
-   this page. stunnel does this as well.
-
-   Of course a malicious user could allow other users to get in through
-   his channel, but that is a problem with every method. Another thing to
-   watch out for is a malicious user on the viewer side (where ssh is
-   running) trying to sneak in through the ssh port redirection there.
-
-   Regarding limiting the set of Unix usernames who can connect, the
-   traditional way would be to further require a VNC password to supplied
-   (-rfbauth, -passwd, etc) and only tell the people allowed in what the
-   VNC password is. A scheme that avoids a second password involves using
-   the -accept option that runs a program to examine the connection
-   information to determine which user is connecting from the local
-   machine. That may be difficult to do, but, for example, the program
-   could use the ident service on the local machine (normally ident
-   should not be trusted over the network, but on the local machine it
-   should be accurate: otherwise root has been compromised and so there
-   are more serious problems! Unfortunately recent Linux distros seem to
-   provide a random string (MD5 hash?) instead of the username.) An
-   example script passed in via -accept scriptname that deduces the Unix
-   username and limits who can be accepted might look something like
-   this:
-#!/bin/sh
-if [ "$RFB_CLIENT_IP" != "127.0.0.1" -o "$RFB_SERVER_IP" != "127.0.0.1" ]; then
-        exit 1  # something fishy... reject it.
-fi
-user=`echo "$RFB_CLIENT_PORT, $RFB_SERVER_PORT" | nc -w 1 $RFB_CLIENT_IP 113 \
-        | grep 'USERID.*UNIX' | head -n 1 | sed -e 's/[\r ]//g' | awk -F: '{pri
-nt $4}'`
-
-for okuser in fred barney wilma betty
-do
-        if [ "X$user" = "X$okuser" ]; then
-                exit 0  # accept it
-        fi
-done
-exit 1  # reject it
-
-   For this to work with ssh port redirection, the ssh option
-   UsePrivilegeSeparation must be enabled otherwise the userid will
-   always be "root".
-
-   Here is a similar example based on Linux netstat(1) output:
-#!/bin/sh
-#
-# accept_local_netstat:  x11vnc -accept command to accept a local
-# vncviewer connection from acceptable users.  Linux netstat -nte is used.

-
-   Q-39: Can I supply an external program to provide my own custom login
-   method (e.g. Dynamic/One-time passwords or non-Unix (LDAP) usernames
-   and passwords)?
-   Yes, there are several possibilities. For background see the FAQ on
-   the -accept where an external program may be run to decide if a VNC
-   client should be allowed to try to connect and log in. If the program
-   (or local user prompted by a popup) answers "yes", then -accept
-   proceeds to the normal VNC and x11vnc authentication methods,
-   otherwise the connection is dropped.
-
-   To provide more direct coupling to the VNC client's username and/or
-   supplied password the following options were added in Sep/2006:
-     * -unixpw_cmd command
-     * -passwdfile cmd:command
-     * -passwdfile custom:command
-
-   In each case "command" is an external command run by x11vnc. You
-   supply it. For example, it may couple to your LDAP system or other
-   servers you set up.
-
-   For -unixpw_cmd the normal -unixpw Login: and Password: prompts are
-   supplied to the VNC viewer and the strings the client returns are then
-   piped into "command" as the first two lines of its standard input. If
-   the command returns success, i.e. exit(0), the VNC client is accepted,
-   otherwise it is rejected.
-
-   For "-passwdfile cmd:command" the command is run and it returns a
-   password list (like a password file, see the -passwdfile read:filename
-   mode.) Perhaps a dynamic, one-time password is retrieved from a server
-   this way.
-
-   For "-passwdfile custom:command" one gets complete control over the
-   VNC challenge-response dialog with the VNC client. x11vnc sends out a
-   string of random bytes (16 by the VNC spec) and the client returns the
-   same number of bytes in a way the server can verify only the
-   authorized user could have created. The VNC protocol specifies DES
-   encryption with a password. If you are willing to modify the VNC
-   viewers, you can have it be anything you want, perhaps a less
-   crackable MD5 hash scheme or one-time pad. Your program will read from
-   its standard input the size of the challenge-response followed by a
-   newline, then the challenge bytes followed by the response bytes. If
-   your command then returns success, i.e. exit(0), the VNC client is
-   accepted, otherwise it is rejected.
-
-   In all cases the "RFB_*" environment variables are set as under
-   -accept. These variables can provide useful information for the
-   externally supplied program to use.
-
-
-   Q-40: Why does x11vnc exit as soon as the VNC viewer disconnects? And
-   why doesn't it allow more than one VNC viewer to connect at the same
-   time?
-
-   These defaults are simple safety measures to avoid someone unknowingly
-   leaving his X11 desktop exposed (to the internet, say) for long
-   periods of time. Use the -forever option (aka -many) to have x11vnc
-   wait for more connections after the first client disconnects. Use the
-   -shared option to have x11vnc allow multiple clients to connect
-   simultaneously.
-
-   Recommended additional safety measures include using ssh (see above),
-   stunnel, -ssl, or a VPN to authenticate and encrypt the viewer
-   connections or to at least use the -rfbauth passwd-file option to use
-   VNC password protection (or -passwdfile) It is up to YOU to apply
-   these security measures, they will not be done for you automatically.
-
-
-   Q-41: Can I limit which machines incoming VNC clients can connect
-   from?
-
-   Yes, look at the -allow and -localhost options to limit connections by
-   hostname or IP address. E.g.
-  x11vnc -allow 192.168.0.1,192.168.0.2
-
-   for those two hosts or
-  x11vnc -allow 192.168.0.
-
-   for a subnet. For individual hosts you can use the hostname instead of
-   the IP number, e.g.: "-allow snoopy", and "-allow darkstar,wombat".
-   Note that -localhost achieves the same thing as "-allow 127.0.0.1"
-
-   For more control, build libvncserver with libwrap support
-   (tcp_wrappers) and then use /etc/hosts.allow See hosts_access(5) for
-   complete details.
-
-
-   Q-42: How do I build x11vnc/libvncserver with libwrap (tcp_wrappers)
-   support?
-
-   Here is one way to pass this information to the configure script:
-  env CPPFLAGS=-DUSE_LIBWRAP LDFLAGS=-lwrap ./configure
-
-   then run make as usual. This requires libwrap and its development
-   package (tcpd.h) to be installed on the build machine. If additional
-   CPPFLAGS or LDFLAGS options are needed supply them as well using
-   quotes.
-
-   The resulting x11vnc then uses libwrap/tcp_wrappers for connections.
-   The service name you will use in /etc/hosts.allow and /etc/hosts.deny
-   is "vnc", e.g.:
-  vnc: 192.168.100.3 .example.com
-
-   Note that if you run x11vnc out of inetd you do not need to build
-   x11vnc with libwrap support because the /usr/sbin/tcpd reference in
-   /etc/inetd.conf handles the tcp_wrappers stuff.
-
-
-   Q-43: Can I have x11vnc only listen on one network interface (e.g.
-   internal LAN) rather than having it listen on all network interfaces
-   and relying on -allow to filter unwanted connections out?
-
-   As of Mar/2005 there is the "-listen ipaddr" option that enables this.
-   For ipaddr either supply the desired network interface's IP address
-   (or use a hostname that resolves to it) or use the string "localhost".
-   For additional filtering simultaneously use the "-allow host1,..."
-   option to allow only specific hosts in.
-
-   This option is useful if you want to insure that no one can even begin
-   a dialog with x11vnc from untrusted network interfaces (e.g. ppp0.)
-   The option -localhost now implies "-listen localhost" since that is
-   what most people expect it to do.
-
-
-   Q-44: Now that -localhost implies listening only on the loopback
-   interface, how I can occasionally allow in a non-localhost via the -R
-   allowonce remote control command?
-
-   To do this specify "-allow localhost". Unlike -localhost this will
-   leave x11vnc listening on all interfaces (but of course only allowing
-   in local connections, e.g. ssh redirs.) Then you can later run "x11vnc
-   -R allowonce:somehost" or use to gui to permit a one-shot connection
-   from a remote host.
-
-
-   Q-45: Can I fine tune what types of user input are allowed? E.g. have
-   some users just be able to move the mouse, but not click or type
-   anything?
-
-   As of Feb/2005, the -input option allows you to do this. "K", "M",
-   "B", "C", and "F" stand for Keystroke, Mouse-motion, Button-clicks,
-   Clipboard, and File-Transfer, respectively. The setting: "-input M"
-   makes attached viewers only able to move the mouse. "-input KMBC,M"
-   lets normal clients do everything and enables view-only clients to
-   move the mouse.
-
-   These settings can also be applied on a per-viewer basis via the
-   remote control mechanism or the GUI. E.g. x11vnc -R input:hostname:M
-
-
-   Q-46: Can I prompt the user at the local X display whether the
-   incoming VNC client should be accepted or not? Can I decide to make
-   some clients view-only? How about running an arbitrary program to make
-   the decisions?
-
-   Yes, look at the "-accept command" option, it allows you to specify an
-   external command that is run for each new client. (use quotes around
-   the command if it contains spaces, etc.) If the external command
-   returns 0 (success) the client is accepted, otherwise with any other
-   return code the client is rejected. See below how to also accept
-   clients view-only.
-
-   The external command will have the RFB_CLIENT_IP environment variable
-   set to the client's numerical IP address, RFB_CLIENT_PORT its port
-   number. Similarly for RFB_SERVER_IP and RFB_SERVER_PORT to allow
-   identification of the tcp virtual circuit. DISPLAY will be set to that
-   of the X11 display being polled. Also, RFB_X11VNC_PID is set to the
-   x11vnc process id (e.g. in case you decided to kill it), RFB_CLIENT_ID
-   will be an id number, and RFB_CLIENT_COUNT the number of other clients
-   currently connected. RFB_MODE will be "accept".
-
-   Built-in Popup Window: As a special case, "-accept popup" will
-   instruct x11vnc to create its own simple popup window. To accept the
-   client press "y" or click mouse on the "Yes" button. To reject the
-   client press "n" or click mouse on the "No" button. To accept the
-   client View-only, press "v" or click mouse on the "View" button. If
-   the -viewonly option has been supplied, the "View" action will not be
-   present: the whole display is view only in that case.
-
-   The popup window times out after 120 seconds, to change this behavior
-   use "-accept popup:N" where N is the number of seconds (use 0 for no
-   timeout.) More tricks: "-accept popupmouse" will only take mouse click
-   responses, while "-accept popupkey" will only take keystroke responses
-   (popup takes both.) After any of the 3 popup keywords you can supply a
-   position of the window: +N+M, (the default is to center the window)
-   e.g. -accept popupmouse+10+10.
-
-   Also as a special case "-accept xmessage" will run the xmessage(1)
-   program to prompt the user whether the client should be accepted or
-   not. This requires that you have xmessage installed and available via
-   PATH. In case it is not already on your system, the xmessage program
-   is available at ftp://ftp.x.org/
-   (End of Built-in Popup Window:)
-
-   To include view-only decisions for the external commands, prefix the
-   command something like this: "yes:0,no:*,view:3 mycommand ..." This
-   associates the three actions: yes(accept), no(reject), and
-   view(accept-view-only), with the numerical return (i.e. exit()) codes.
-   Use "*" instead of a number to set the default action (e.g. in case
-   the external command returns an unexpected return code.)
-
-   Here is an example -accept script called accept_or_lock. It uses
-   xmessage and xlock (replace with your screen lock command, maybe it is
-   "xscreensaver-command -lock", or kdesktop_lock, or "dtaction
-   LockDisplay".) It will prompt the user at the X display whether to
-   accept, reject, or accept view-only the client, but if the prompt
-   times out after 60 seconds the screen is locked and the VNC client is
-   accepted. This allows the remote access when no one is at the display.
-#!/bin/sh
-#
-# accept_or_lock: prompt user at X display whether to accept an incoming
-#                 VNC connection.  If timeout expires, screen is locked
-#                 and the VNC viewer is accepted (allows remote access
-#                 when no one is sitting at the display.)
-#
-# usage: x11vnc ... -forever -accept 'yes:0,no:*,view:4 accept_or_lock'

-rc=$?
-if [ $rc = 0 ]; then
-        xlock & # or "xlock -mode blank" for no animations.

-exit 1
-
-   Stefan Radman has written a nice dtksh script dtVncPopup for use in
-   CDE environments to do the same sort of thing. Information on how to
-   use it is found at the top of the file. He encourages you to provide
-   feedback to him to help improve the script.
-
-   Note that in all cases x11vnc will block while the external command or
-   popup is being run, so attached clients will not receive screen
-   updates, etc during this period.
-
-   To run a command when a client disconnects, use the "-gone command"
-   option. This is for the user's convenience only: the return code of
-   the command is not interpreted by x11vnc. The same environment
-   variables are set as in "-accept command" (except that RFB_MODE will
-   be "gone".)
-
-   As of Jan/2006 the "-afteraccept command" option will run the command
-   only after the VNC client has been accepted and authenticated. Like
-   -gone the return code is not interpreted. RFB_MODE will be
-   "afteraccept".)
-
-
-   Q-47: I start x11vnc as root because it is launched via inetd(8) or a
-   display manager like gdm(1). Can I have x11vnc later switch to a
-   different user?
-
-   As of Feb/2005 x11vnc has the -users option that allows things like
-   this. Please read the documentation on it (also in the x11vnc -help
-   output) carefully for features and caveats. It's use can often
-   decrease security unless care is taken.
-
-   BTW, a nice use of it is "-users +nobody" that switches to the Unix
-   user nobody right after connections to the X display are established.
-
-   In any event, while running x11vnc as root, remember it comes with no
-   warranty ;-).
-
-
-   Q-48: I use a screen-lock when I leave my workstation (e.g.
-   xscreensaver or xlock.) When I remotely access my workstation desktop
-   via x11vnc I can unlock the desktop fine, but I am worried people will
-   see my activities on the physical monitor. What can I do to prevent
-   this, or at least make it more difficult?
-
-   Probably most work environments would respect your privacy if you
-   powered off the monitor. Also remember if people have physical access
-   to your workstation they basically can do anything they want with it
-   (e.g. install a backdoor for later use, etc.)
-
-   In any event, as of Jun/2004 there is an experimental utility to make
-   it more difficult for nosey people to see your x11vnc activities. The
-   source for it is blockdpy.c The idea behind it is simple (but
-   obviously not bulletproof): when a VNC client attaches to x11vnc put
-   the display monitor in the DPMS "off" state, if the DPMS state ever
-   changes immediately start up the screen-lock program. The x11vnc user
-   will notice something is happening and think about what to do next
-   (while the screen is in a locked state.)
-
-   This works (or at least has a chance of working) because if the
-   intruder moves the mouse or presses a key on the keyboard, the monitor
-   wakes up out of the DPMS off state, and this induces the screen lock
-   program to activate as soon as possible. Of course there are cracks in
-   this, the eavesdropper could detach your monitor and insert a non-DPMS
-   one, and there are race conditions. As mentioned above this is not
-   bulletproof. A really robust solution would likely require X server
-   and perhaps even video hardware support.
-
-   The blockdpy utility is launched by the -accept option and told to
-   exit via the -gone option (the vnc client user should obviously
-   re-lock the screen before disconnecting!) Instructions can be found in
-   the source code for the utility at the above link. Roughly it is
-   something like this:
-  x11vnc ... -accept "blockdpy -bg -f $HOME/.bdpy" -gone "touch $HOME/.bdpy"
-
-   but please read the top of the file.
-
-   Update: As of Feb/2007 there is some builtin support for this:
-   -forcedpms and -clientdpms however, they are probably less robust than
-   the above blockdpy.c scheme, since if the person floods the physical
-   machine with mouse or pointer input he can usually see flashes of the
-   screen before the monitor is powered off again. See also the -grabkbd,
-   -grabptr, and -grabalways options.
-
-
-   Q-49: Can I have x11vnc automatically lock the screen when I
-   disconnect the VNC viewer?
-
-   Yes, a user mentions he uses the -gone option under CDE to run a
-   screen lock program:
-  x11vnc -display :0 -forever -gone 'dtaction LockDisplay'
-
-   Other possibilities are:
-  x11vnc -display :0 -forever -gone 'xscreensaver-command -lock'
-  x11vnc -display :0 -forever -gone 'kdesktop_lock'
-  x11vnc -display :0 -forever -gone 'xlock &'
-  x11vnc -display :0 -forever -gone 'xlock -mode blank &'
-
-   Here is a scheme using the -afteraccept option (in version 0.8) to
-   unlock the screen after the first valid VNC login and to lock the
-   screen after the last valid VNC login disconnects:
-  x11vnc -display :0 -forever -shared -afteraccept ./myxlocker -gone ./myxlocke
-r
-
-   Where the script ./myxlocker is:
-#!/bin/sh
-
-#/usr/bin/env | grep RFB_ | sort        # for viewing RFB_* settings.
-
-if [ "X$RFB_MODE" = "Xafteraccept" ]; then
-        if [ "X$RFB_STATE" = "XNORMAL" ]; then  # require valid login
-                if [ "X$RFB_CLIENT_COUNT" = "X1" ]; then
-                        killall xlock   # Linux only.
-                fi
-        fi
-elif [ "X$RFB_MODE" = "Xgone" ]; then
-        if [ "X$RFB_STATE" = "XNORMAL" ]; then  # require valid login
-                if [ "X$RFB_CLIENT_COUNT" = "X0" ]; then
-                        xlock -mode blank &
-                fi
-        fi
-fi
-
-   Note the xlock option "-mode blank" to avoid animations.
-
-   There is a problem if you have x11vnc running this way in -forever
-   mode and you hit Ctrl-C to stop it. The xlock (or other program) will
-   get killed too. To work around this make a little script called
-   setpgrp that looks like:
-#!/usr/bin/perl
-setpgrp(0, 0);
-exec @ARGV;
-
-   then use -gone "setpgrp xlock &", etc.
-   [Encrypted Connections]
-
-   Q-50: How can I tunnel my connection to x11vnc via an encrypted SSH
-   channel between two Unix machines?
-
-   See the description earlier on this page on how to tunnel VNC via SSH
-   from Unix to Unix. A number of ways are described along with some
-   issues you may encounter.
-
-   Other secure encrypted methods exists, e.g. stunnel, IPSEC, various
-   VPNs, etc.
-
-   See also the Enhanced TightVNC Viewer (SSVNC) page where much of this
-   is now automated.
-
-
-   Q-51: How can I tunnel my connection to x11vnc via an encrypted SSH
-   channel from Windows using an SSH client like Putty?
-
-   Above we described how to tunnel VNC via SSH from Unix to Unix, you
-   may want to review it. To do this from Windows using Putty it would go
-   something like this:
-     * In the Putty dialog window under 'Session' enter the hostname or
-       IP number of the Unix machine with display to be viewed.
-     * Make sure the SSH protocol is selected and the server port is
-       correct.
-     * Under 'Connections/SSH/Tunnels' Add a Local connection with
-       'Source port:  5900' and 'Destination:  localhost:5900'
-     * Log into the remote machine by pressing 'Open' and supplying
-       username, password, etc.
-     * In that SSH shell, start up x11vnc by typing the command: x11vnc
-       -display :0 plus any other desired options (e.g. -localhost.)
-     * Finally, start up your VNC Viewer in Windows and enter
-       'localhost:0' as the VNC server.
-
-   You can keep all of the settings in a Putty 'Saved Session'. Also,
-   once everything is working, you can consider putting x11vnc -display
-   :0 (plus other cmdline options) in the 'Remote command' Putty setting
-   under 'Connections/SSH'.
-
-   See also the Enhanced TightVNC Viewer (SSVNC) page where much of this
-   is now automated via the Putty plink utility.
-
-   For extra protection feel free to run x11vnc with the -localhost and
-   -rfbauth/-passwdfile options.
-
-   If the machine you SSH into via Putty is not the same machine with the
-   X display you wish to view (e.g. your company provides incoming SSH
-   access to a gateway machine), then you need to change the above Putty
-   dialog setting to: 'Destination: otherhost:5900', Once logged in,
-   you'll need to do a second login (ssh or rsh) to the workstation
-   machine 'otherhost' and then start up x11vnc on it. This can also be
-   automated by Chaining SSH's.
-
-   As discussed above another option is to first start the VNC viewer in
-   "listen" mode, and then launch x11vnc with the "-connect localhost"
-   option to establish the reverse connection. In this case a Remote port
-   redirection (not Local) is needed for port 5500 instead of 5900 (i.e.
-   'Source port:  5500' and 'Destination:  localhost:5500' for a Remote
-   connection.)
-
-
-   Q-52: How can I tunnel my connection to x11vnc via an encrypted SSL
-   channel using an external tool like stunnel?
-
-   It is possible to use a "lighter weight" encryption setup than SSH or
-   IPSEC. SSL tunnels such as stunnel (also stunnel.org) provide an
-   encrypted channel without the need for Unix users, passwords, and key
-   passphrases required for ssh (and at the other extreme SSL can also
-   provide a complete signed certificate chain of trust.) On the other
-   hand, since SSH is usually installed everywhere and firewalls often
-   let its port through, ssh is frequently the path of least resistance
-   (it also nicely manages public keys for you.)
-
-   Update: As of Feb/2006 x11vnc has the options -ssl, -stunnel, and
-   -sslverify to provide integrated SSL schemes. They are discussed in
-   the Next FAQ (you probably want to skip to it now.)
-
-   We include these non-built-in method descriptions below for historical
-   reference. They are handy because can be used to create SSL tunnels to
-   any VNC (or other type of) server.
-
-
-   Here are some basic examples using stunnel but the general idea for
-   any SSL tunnel utility is the same:
-     * Start up x11vnc and constrain it to listen on localhost.
-     * Then start up the SSL tunnel running on the same machine to
-       forward incoming connections to that x11vnc.
-     * Set up and run a similar SSL tunnel for the outgoing connection on
-       the VNC viewer machine pointing it to the SSL/x11vnc server.
-     * Optionally, set up server (or even client) public/private keys for
-       use in authenticating one side to the other.
-     * Finally, start the VNC Viewer and tell it to connect to the local
-       port (e.g. a vnc display localhost:0) where its outgoing SSL
-       tunnel is listening.
-
-   We'll first use the stunnel version 3 syntax since it is the most
-   concise and Unixy.
-
-   Start up x11vnc listening on port 5900:
-  x11vnc -display :0 -rfbport 5900 -localhost -bg -passwdfile ~/mypass
-
-   Then start stunnel (version 3, not 4) with this command:
-  stunnel -d 5901 -r 5900 -p /path/to/stunnel.pem
-
-   The above two commands are run on host "far-away.east". The
-   stunnel.pem is the self-signed PEM file certificate created when
-   stunnel is built. One can also create certificates signed by
-   Certificate Authorities or self-signed if desired using the x11vnc
-   utilities described there.
-
-   SSL Viewers:  Next, on the VNC viewer side we need an SSL tunnel to
-   encrypt the outgoing connection. The nice thing is any SSL tunnel can
-   be used because the protocol is a standard. For this example we'll
-   also use stunnel on the viewer side on Unix. First start up the
-   client-side stunnel (version 3, not 4):
-  stunnel -c -d localhost:5902 -r far-away.east:5901
-
-   Then point the viewer to the local tunnel on port 5902:
-  vncviewer -encodings "copyrect tight zrle hextile" localhost:2
-
-   That's it.  Note that the ss_vncviewer script can automate this
-   easily, and so can the Enhanced TightVNC Viewer (SSVNC) package.
-
-   Be sure to use a VNC password because unlike ssh by default the
-   encrypted SSL channel provides no authentication (only privacy.) With
-   some extra configuration one could also set up certificates to provide
-   authentication of either or both sides as well (and hence avoid
-   man-in-the-middle attacks.) See the stunnel and openssl documentation
-   and also the key management section for details.
-
-   stunnel has also been ported to Windows, and there are likely others
-   to choose from for that OS. Much info for using it on Windows can be
-   found at the stunnel site and in this article The article also shows
-   the detailed steps to set up all the authentication certificates. (for
-   both server and clients, see also the x11vnc utilities that do this.)
-   The default Windows client setup (no certs) is simpler and only 4
-   files are needed in a folder: stunnel.exe, stunnel.conf, libssl32.dll,
-   libeay32.dll. We used an stunnel.conf containing:
-# stunnel.conf:
-client = yes
-options = ALL
-[myvncssl]
-accept = localhost:5902
-connect = far-away.east:5901
-
-   then double click on the stunnel.exe icon to launch it (followed by
-   pointing the VNC viewer to localhost:2).
-
-
-   stunnel inetd-like mode:
-
-   As an aside, if you don't like the little "gap" of unencrypted TCP
-   traffic (and a localhost listening socket) on the local machine
-   between stunnel and x11vnc it can actually be closed by having stunnel
-   start up x11vnc in -inetd mode:
-  stunnel -p /path/to/stunnel.pem -P none -d 5900 -l ./x11vnc_sh
-
-   Where the script x11vnc_sh starts up x11vnc:
-#!/bin/sh
-x11vnc -q -inetd -display :0 -passwdfile ~/mypass
-
-   Note that this creates a separate x11vnc process for each incoming
-   connection (as any inetd x11vnc usage would), but for the case of
-   normally just one viewer at a time it should not be a big problem.
-
-
-   stunnel 4 syntax:
-
-   Somewhat sadly, the stunnel version 4 syntax is not so amenable to the
-   command line or scripts. You need to create a config file with the
-   parameters. E.g.:
-  stunnel x11vnc.cfg
-
-   Where the file x11vnc.cfg contains:
-foreground = yes
-pid =
-cert = /path/to/stunnel.pem
-[x11vnc_stunnel]
-accept  = 5901
-connect = 5900
-
-   One nice thing about version 4 is often the PEM file does not need to
-   be specified because stunnel finds it in its installed area. One other
-   gotcha the PEM file is usually only readable by root (it has the
-   private key afterall), so you'll need to relax the permissions or make
-   a copy that the user running x11vnc/stunnel can read.
-
-
-   SSL VNC Viewers:
-
-   Regarding VNC viewers that "natively" do SSL unfortunately there do
-   not seem to be many. The SingleClick UltraVNC Java Viewer is SSL and
-   is compatible with x11vnc's -ssl option and stunnel.) Commercial
-   versions of VNC seem to have some SSL-like encryption built in, but we
-   haven't tried those either and they probably wouldn't work since their
-   (proprietary) SSL-like negotiation is likely embedded in the VNC
-   protocol unlike our case where it is external.
-
-   Note: as of Mar/2006 libvncserver/x11vnc provides a SSL-enabled Java
-   applet that can be served up via the -httpdir or -http options when
-   -ssl is enabled. It will also be served via HTTPS via either the VNC
-   port (e.g. https://host:5900/) or a 2nd port via the -https option.
-
-   In general current SSL VNC solutions are not particularly "seemless".
-   But it can be done, and with a wrapper script on the viewer side and
-   the -stunnel or -ssl option on the server side it works well and is
-   convenient. Here is a simple script ss_vncviewer that automates
-   running stunnel on the VNC viewer side on Unix a little more carefully
-   than the commands printed above. (One could probably do a similar
-   thing with a .BAT file on Windows in the stunnel folder.)
-
-   Update Jul/2006: we now provide an Enhanced TightVNC Viewer (SSVNC)
-   package that starts up STUNNEL automatically along with some other
-   features. All binaries (stunnel, vncviewer, and some utilities) are
-   provided in the package. It works on Unix, Mac OS X, and Windows.
-
-
-   Q-53: Does x11vnc have built-in SSL tunneling?
-
-   You can read about non-built-in methods in the Previous FAQ for
-   background.
-
-   SSL tunnels provide an encrypted channel without the need for Unix
-   users, passwords, and key passphrases required for ssh (and at the
-   other extreme SSL can also provide a complete signed certificate chain
-   of trust.) On the other hand, since SSH is usually installed
-   everywhere and firewalls often let its port through, ssh is frequently
-   the path of least resistance.
-
-   Built-in SSL x11vnc options:
-
-   As of Feb/2006 the x11vnc -ssl option automates the SSL tunnel
-   creation on the x11vnc server side. An SSL-enabled Java Viewer applet
-   is also provided that can be served via HTTP or HTTPS to automate SSL
-   on the client side.
-
-   The -ssl mode uses the www.openssl.org library if available at build
-   time.
-
-   The mode requires an SSL certificate and key (i.e. .pem file.) These
-   are usually created via the openssl(1) program (in fact in for "-ssl"
-   (same as "-ssl SAVE") it will run openssl for you automatically.) So
-   the SSL is not completely "built-in" since this external tool needs to
-   be installed, but at least x11vnc runs it for you automatically.
-
-   An -ssl example:
-  x11vnc -display :0 -ssl -passwdfile ~/mypass
-
-   You'll get output like this:
-  09/04/2006 19:27:35 Creating a self-signed PEM certificate...
-  09/04/2006 19:27:35
-  ...
-
-  The SSL VNC desktop is:  far-away.east:0
-  PORT=5900
-  SSLPORT=5900
-
-   In this case openssl(1) was used to create a PEM automatically. It
-   will prompt you if you want to protect it with with a passphrase. Use
-   "-ssl SAVE_NOPROMPT" to not be prompted. Use "-ssl TMP" to create a
-   temporary self-signed cert that will be discarded when x11vnc exits.
-
-   Update: As of Nov/2008 x11vnc also supports the VeNCrypt SSL/TLS
-   tunnel extension to the VNC protocol. The older ANONTLS method (vino)
-   is also supported. This support is on by default when the -ssl option
-   is in use and can be fine-tuned using these options: -vencrypt,
-   -anontls, and -sslonly.
-
-   The normal x11vnc -ssl operation is somewhat like a URL method
-   vncs://hostname if vnc://hostname indicates a standard unencrypted VNC
-   connection. Just as https://hostname is an SSL encrypted version of
-   http://hostname. The entire VNC session goes through the SSL tunnel.
-   VeNCrypt, on the other hand, switches to SSL/TLS early in the VNC
-   protocol handshake. x11vnc 0.9.6 supports both simultaneously when
-   -ssl is active.
-
-
-   SSL VNC Viewers:. Viewer-side will need to use SSL as well. See the
-   next FAQ and here for SSL enabled VNC Viewers, including SSVNC, to
-   connect to the above x11vnc via SSL.
-
-
-   As seen above, the PEM (privacy enhanced mail) file does not need to
-   be supplied if the openssl(1) command is available in PATH, in that
-   case a self-signed, certificate good the current and subsequent x11vnc
-   sessions is created (this may take a while on very slow machines.)
-
-   In general, the PEM file contains both the Certificate (i.e. public
-   key) and the Private Key. Because of the latter, the file should be
-   protected from being read by untrusted users. The best way to do this
-   is to encrypt the key with a passphrase (note however this requires
-   supplying the passphrase each time x11vnc is started up.)
-
-   See the discussion on x11vnc Key Management for some utilities
-   provided for creating and managing certificates and keys and even for
-   creating your own Certificate Authority (CA) for signing VNC server
-   and client certificates. This may be done by importing the certificate
-   into Web Browser or Java plugin keystores, or pointing stunnel to it.
-   The wrapper script ss_vncviewer provides an example on unix (see the
-   -verify option.)
-
-   Here are some notes on the simpler default (non-CA) operation. To have
-   x11vnc save the generated certificate and key, use the "SAVE" keyword
-   like this:
-  x11vnc -ssl SAVE -display :0 ...
-
-   (this is the same as the default: "-ssl".) This way it will be saved
-   in the default directory ~/.vnc/certs/ as server.crt (the certificate
-   only) and server.pem (both certificate and private key.) This opens up
-   the possibility of copying the server.crt to machines where the VNC
-   Viewer will be run to enable authenticating the x11vnc SSL VNC server
-   to the clients. When authentication takes place this way (or via the
-   more sophisticated CA signing described here), then
-   Man-In-The-Middle-Attacks are prevented. Otherwise, the SSL encryption
-   only provides protection against passive network traffic "sniffing"
-   (i.e. you are not protected against M-I-T-M attacks.) Nowadays, most
-   people seem mostly concerned mainly about passive sniffing (and the
-   default x11vnc SSL mode protects against it.) Note that there are
-   hacker tools like dsniff/webmitm and cain that implement SSL
-   Man-In-The-Middle attacks. They rely on the client not bothering to
-   check the cert.
-
-
-   One can test to some degree that SSL is working after starting x11vnc
-   with the -stunnel or -ssl option. From another machine one can use the
-   openssl command something like this:
- openssl s_client -debug -msg -showcerts -connect far-away.east:5900
-
-   After all of the debugging output and informational messages you'll
-   see the string "RFB 003.008" that came from x11vnc. Pointing a web
-   browser connecting to: https://far-away.east:5900/ and then viewing
-   the SSL certificate information about the connection in the panels
-   will also work.
-
-   Note: If you serve up the SSL enabled Java VNC Viewer via something
-   like:
- x11vnc -ssl -httpdir /usr/local/share/x11vnc/classes/ssl
-
-   (or just the -http option), you can test it out completely using that,
-   including using https to download it into the browser and connect to
-   x11vnc.
-
-
-   The older -stunnel option: Before the -ssl option there was a
-   convenience option -stunnel that would start an external SSL tunnel
-   for you using stunnel. The -ssl method is the preferred way, but for
-   historical reference we keep the -stunnel info here.
-
-   The -stunnel mode requires the stunnel.mirt.net command stunnel(8) to
-   be installed on the system.
-
-   Some -stunnel examples:
-  x11vnc -display :0 -stunnel /path/to/stunnel.pem -passwdfile ~/mypass
-
-  x11vnc -display :0 -stunnel SAVE ...
-
-   You'll get output like this:
-  The VNC desktop is:      localhost:50
-  The SSL VNC desktop is:  far-away.east:0
-  PORT=5950
-  SSLPORT=5900
-
-   That indicates stunnel is listening on port 5900 for incoming
-   SSL-wrapped VNC connections from viewers. x11vnc is listening for
-   local connections on port 5950 in this case (remote viewers cannot
-   connect to it directly.) For -stunnel to work the stunnel command must
-   be installed on the machine and available in PATH (note stunnel is
-   often installed in sbin directories rather than bin.) Note that the
-   default "-stunnel" by itself creates a temporary cert (as in "-ssl
-   TMP".)
-
-
-   Q-54: How do I use VNC Viewers with built-in SSL tunneling?
-
-   Notes on using "native" VNC Viewers with SSL:
-
-   There aren't any native VNC Viewers that do SSL (ask your VNC viewer
-   developer to add the feature.) So a tunnel must be setup that you
-   point the VNC Viewer to. This is often STUNNEL. You can do this
-   manually, or use the ss_vncviewer script on Unix, or our Enhanced
-   TightVNC Viewer (SSVNC) package on Unix, Windows, or MacOSX. See the
-   next section for Java Web browser SSL VNC Viewers (you only need a
-   Java-enabled Web browser for it to work.)
-
-   Notes on the SSL enabled Java VNC Viewer provided in x11vnc
-   classes/ssl/VncViewer.jar:
-
-   A Java applet VNC Viewer allows you to connect to a VNC Server from a
-   Java-enabled Web browser.
-
-   The SSL enabled Java VNC Viewer (VncViewer.jar) in the x11vnc package
-   supports only SSL based connections by default. As mentioned above the
-   -httpdir can be used to specify the path to .../classes/ssl. A typical
-   location might be /usr/local/share/x11vnc/classes/ssl. Or -http can be
-   used to try to have it find the directory automatically.
-
-   Also note that the SingleClick UltraVNC Java Viewer is compatible with
-   x11vnc's -ssl SSL mode. (We tested it this way: "java -cp
-   ./VncViewer.jar VncViewer HOST far-away.east PORT 5900 USESSL 1
-   TRUSTALL 1")
-
-   The Java viewer uses SSL to communicate securely with x11vnc. Note
-   that the applet can optionally also be downloaded into your web
-   browser via HTTPS (which is HTTP over SSL.) This way the HTML page and
-   the Java applet itself are also delivered securely with SSL (as
-   opposed to only the VNC traffic being encrypted with SSL.)
-
-   For this case the output will be something like this:
-  x11vnc -ssl SAVE -http
-  ...
-  The SSL VNC desktop is:  far-away.east:0
-  Java SSL viewer URL:     https://far-away.east:5900/
-  Java SSL viewer URL:     http://far-away.east:5800/
-  PORT=5900
-  SSLPORT=5900
-
-   Indicating the two URLs (the first one encrypted, the second not) one
-   could point the web browser at to get the VNC viewer applet. E.g. put
-   this
-   http://far-away.east:5800/
-
-   or:
-   https://far-away.east:5900/
-
-   into your Java-enabled Web browser.
-
-   Note that KDE's Konqueror web browser seems to have problems with
-   https Java applets, so you'll have to use the http/5800 with it (if
-   you get https/5900 working let us know how you did it.)
-
-   If you are using a router/firewall with port-redirection, and you are
-   redirecting ports other than the default ones (5800, 5900) listed
-   above see here.
-
-   The https service provided thru the actual VNC port (5900 in the above
-   example) can occasionally be slow or unreliable (it has to read some
-   input and try to guess if the connection is VNC or HTTP.) If it is
-   unreliable for you and you still want to serve the Java applet via
-   https, use the -https option to get an additional port dedicated to
-   https (its URL will also be printed in the output.)
-
-   Another possibility is to add the GET applet parameter:
-  https://far-away.east:5900/?GET=1
-
-   This will have the VNC Viewer send a special HTTP GET string "GET
-   /request.https.vnc.connection HTTP/1.0" that x11vnc will notice more
-   quickly as a request for a VNC connection. Otherwise it must wait for
-   a timeout to expire before it assumes a VNC connection.
-
-   You may also use "urlPrefix=somestring" to have /somestring prepended
-   to /request.https.vnc.connection". Perhaps you are using a web server
-   proxy scheme to enter a firewall or otherwise have rules applied to
-   the URL. If you need to have any slashes "/" in "somestring" use
-   "_2F_" (a deficiency in libvncserver prevents using the more natural
-   "%2F".)
-
-   You apply multiple applet parameters in the regular URL way, e.g.:
-  https://far-away.east:5900/?GET=1&urlPrefix=mysubdir&...
-
-   All of the x11vnc Java Viewer applet parameters are described in the
-   file classes/ssl/README
-
-
-   Tips on Getting the SSL Java Applet Working the First Time:
-   Unfortunately, it can be a little tricky getting the SSL VNC Java
-   Viewer working with x11vnc. Here are some tips to getting working the
-   first time (afterwards you can incrementally customize with more
-   complex settings.)
-     * First try it on the LAN: Do NOT try to have it work the first time
-       going through firewalls, Web proxies, home router port
-       redirections, or Apache portal. Just try a direct connection over
-       your LAN first (if you only have 1 machine and no LAN, just do a
-       direct connection to the same machine: localhost.) If the LAN
-       machine you run x11vnc on has its own host-level firewall (most
-       linux machine come with that on by default), disable it or at
-       least let tcp ports 5800-6000 through.
-     * First try HTTP to download the Java Applet: x11vnc can serve both
-       the Java Applet jar file and VNC out of the same port (both
-       tunneled through SSL, see below.) But it can lead to timing and
-       other problems. So first try HTTP instead of HTTPS to download the
-       Applet jar file (VncViewer.jar.) That is to say try
-       http://hostname:5800 in your web browser first before trying
-       https://hostname:5900. x11vnc will print out the ports and URLs it
-       is using, so use the HTTP one it prints out.
-     * Always Restart the Browser: If you are having failures and have to
-       repeatedly retry things ALWAYS restart the browser (i.e.
-       completely exit it and then start a new browser process) each
-       time. Otherwise as you are changing things the browser may
-       "remember" failed applet downloads, etc. and just add to the
-       confusion and irreproducibility. If you see it trying to download
-       VncViewer.class (instead of VncViewer.jar) you know it is really
-       confused and needs to be restarted.
-     * Step Lively: If you get Browser or Java VM or VNC Viewer applet
-       dialog boxes saying things like "Do you want to trust this
-       certificate?" or "The hostname does not match the one on the
-       certificate", etc. just go through them as quickly as possible.
-       x11vnc cannot wait forever for each SSL connection, and so if you
-       dawdle too long inspecting the certs, etc it can lead to problems.
-       Get it working first before taking your time to read the details
-       in the dialogs, etc.
-     * No inetd, Please: Even if you intend to deploy via inetd or xinetd
-       eventually, get that working later (and remember do not use
-       something like "-ssl TMP" that creates a new temporary SSL
-       certificate for every new socket connection.)
-     * Nothing Fancy: Do not try fancy stuff like -svc, -create, -unixpw,
-       "-users unixpw=", "-users sslpeer=", -sslverify, etc. Just get the
-       simplest connection working first and then incrementally add what
-       you need.
-
-   So the recommended test command lines are:
-   x11vnc -ssl SAVE -http
-   x11vnc -ssl SAVE -httpdir /path/to/x11vnc/classes/ssl
-
-   Use the latter if x11vnc cannot automatically find the classes/ssl
-   directory (this what the -http option instructs it to do.) Then point
-   your browser to the HTTP (not HTTPS) URL it prints out.
-
-   Following the above guidelines, did it work? If so, Congratulations!!
-   you created an SSL encrypted connection between the SSL Java applet
-   running in your web browser and x11vnc. The fact that you used HTTP
-   instead of HTTPS to download the applet is not the end of the world
-   (some users do it this way), the main thing is that the VNC traffic is
-   encrypted with SSL. If you are having trouble even with the above
-   baseline test case feel free to contact me (please send the Full
-   x11vnc output, not just part of it; the complete x11vnc command line;
-   the URL(s) entered in the browser; the full Java Console output; and
-   anything else you can think of.)
-
-   Next, you can add the features you want one by one testing it still
-   works each time. I suggest first turning on the HTTPS applet download
-   (https://hostname:5900) if that is what you intend to use. That one
-   gives the most trouble because of the ambiguity of passing two
-   different protocols (HTTP and VNC) through the same SSL service port.
-
-   Next, turn on inetd if you intend to use that (this can be tricky too,
-   be sure to use -oa logfile and inspect it carefully if there are
-   problems.) If you are going to use non-standard ports (e.g. "-rfbport
-   443" as root), work on that next. Then enable the firewall, router
-   port redirection channel (you will somehow need to be outside to do
-   that, maybe test that through another VNC session.)
-
-   Then, if you plan to use them, enable "fancy stuff" like "-svc" or
-   "-unixpw", etc, etc. Be sure to add a password either "-rfbauth" or
-   "-unixpw" or both. If you need to have the web browser use a corporate
-   Web Proxy (i.e. it cannot connect directly) work on that last. Ditto
-   for the Apache portal.
-
-
-   Router/Firewall port redirs:  If you are doing port redirection at
-   your router to an internal machine running x11vnc AND the internet
-   facing port is different from the internal machine's VNC port, you
-   will need to apply the PORT applet parameter to indicate to the applet
-   the Internet facing port number (otherwise by default the internal
-   machine's port, say 5900, is sent and that of course is rejected at
-   the firewall/router.) For example:
-  https://far-away.east:443/?GET=1&PORT=443
-
-   So in this example the user configures his router to redirect
-   connections to port 443 on his Internet side to, say, port 5900 on the
-   internal machine running x11vnc. See also the -httpsredir option that
-   will try to automate this for you.
-
-   To configure your router to do port redirection, see its instructions.
-   Typically, from the inside you point a web browser to a special URL
-   (e.g. http://192.168.1.1) and you get a web interface to configure it.
-   Look for something like "Port Redirection" or "Port Forwarding",
-   probably under "Advanced" or something like that. If you have a Linux
-   or Unix system acting as your firewall/router, see its firewall
-   configuration.
-
-   You can also use x11vnc options -rfbport NNNNN and -httpport NNNNN to
-   match the ports that your firewall will be redirecting to the machine
-   where x11vnc is run.
-
-
-   Tedious Dialogs: If you do serve the SSL enabled Java viewer via https
-   be prepared for quite a number of "are you sure you trust this site?"
-   dialogs:
-     * First from the Web browser that cannot verify the self-signed
-       certificate when it downloads index.vnc.
-     * From the Web browser again noting that the common name on the
-       certificate does not match the hostname of the remote machine.
-     * Next from the Java VM that cannot verify the self-signed
-       certificate when it downloads VncViewer.jar.
-     * And also from the Java VM again noting that the common name on the
-       certificate does not match the hostname of the remote machine.
-     * Finally from the Java VncViewer applet itself saying it cannot
-       verify the certificate! (or a popup asking you if you want to see
-       the certificate.)
-
-   Note that sometimes if you pause too long at one of the above dialogs
-   then x11vnc may exceed a timeout and assume the current socket
-   connection is VNC instead of the HTTPS it actually is (but since you
-   have paused too long at the dialog the GET request comes too late.)
-   Often hitting Reload and going through the dialogs more quickly will
-   let you connect. The Java VM dialogs are the most important ones to
-   NOT linger at. If you see in the x11vnc output a request for
-   VncViewer.class instead of VncViewer.jar it is too late... you will
-   need to completely restart the Web browser to get it to try for the
-   jar again. You can use the -https option if you want a dedicated port
-   for HTTPS connections instead of sharing the VNC port.
-
-   To see example x11vnc output for a successful https://host:5900/
-   connection with the Java Applet see This Page. And here is a newer
-   example including the Java Console output.
-
-   All of the x11vnc Java Viewer applet parameters are described in the
-   file classes/ssl/README
-
-
-   Notes on the VNC Viewer ss_vncviewer wrapper script:
-
-   If you want to use a native VNC Viewer with the SSL enabled x11vnc you
-   will need to run an external SSL tunnel on the Viewer side. There do
-   not seem to be any native SSL VNC Viewers outside of our x11vnc and
-   SSVNC packages. The basic ideas of doing this were discussed for
-   external tunnel utilities here.
-
-   The ss_vncviewer script provided with x11vnc and SSVNC can set up the
-   stunnel tunnel automatically on unix as long as the stunnel command is
-   installed on the Viewer machine and available in PATH (and vncviewer
-   too of course.) Note that on a Debian based system you will need to
-   install the package stunnel4 not stunnel. You can set the environment
-   variables STUNNEL and VNCVIEWERCMD to point to the correct programs if
-   you want to override the defaults.
-
-   Here are some examples:
-  1)  ss_vncviewer far-away.east:0
-
-  2)  ss_vncviewer far-away.east:0 -encodings "copyrect tight zrle hextile"
-
-  3)  ss_vncviewer -verify ./server.crt far-away.east:0
-
-  4)  ss_vncviewer -mycert ./client.pem far-away.east:0
-
-  5)  ss_vncviewer -proxy far-away.east:8080 myworkstation:0
-
-   The first one is the default mode and accepts the x11vnc certificate
-   without question. The second one is as the first, but adds the
-   -encodings options to the vncviewer command line.
-
-   The third one requires that the x11vnc server authenticate itself to
-   the client against the certificate in the file ./server.crt (e.g. one
-   created by "x11vnc -ssl SAVE" and safely copied to the VNC viewer
-   machine.)
-
-   The fourth one is for VNC Viewer authentication, it uses ./client.pem
-   to authenticate itself to x11vnc. One can supply both -verify and
-   -mycert simultaneously.
-
-   The fifth one shows that Web proxies can be used if that is the only
-   way to get out of the firewall. If the "double proxy" situation arises
-   separate the two by commas. See this page for more information on how
-   Web proxies come into play.
-
-   If one uses a Certificate Authority (CA) scheme described here, the
-   wrapper script would use the CA cert instead of the server cert:
-  3')  ss_vncviewer -verify ./cacert.crt far-away.east:0
-
-   Update Jul/2006: we now provide an Enhanced TightVNC Viewer (SSVNC)
-   package that starts up STUNNEL automatically along with some other
-   features. All binaries (stunnel, vncviewer, and some utilities) are
-   provided in the package. It works on Unix, Mac OS X, and Windows.
-
-
-   Q-55: How do I use the Java applet VNC Viewer with built-in SSL
-   tunneling when going through a Web Proxy?
-   The SSL enabled Java VNC Viewer and firewall Proxies:
-
-   SSL and HTTPS aside, there is a general problem with Firewall Proxies
-   and Java Applets that open sockets. The applet is downloaded
-   successfully (through the browser) using HTTP and the proxy, but when
-   the applet tries to reconnect to the originating host (the only one
-   allowed by security) it does not use the proxy channel. So it cannot
-   reconnect to the server the applet came from!
-
-   We have found a convenient workaround: in the directory where
-   VncViewer.jar resides there is a digitally signed version of the same
-   applet called SignedVncViewer.jar. Since the applet is digitally
-   signed, there will be an additional dialog from the Java VM plugin
-   asking you if you want to trust the applet fully.
-
-   You should say "Yes". If you do, the applet will be run in a mode
-   where it can try to determine the firewall proxy host name and port
-   (it will ask you for them if it cannot find them.) This way it can
-   connect directly to the Proxy and then request the CONNECT method to
-   be redirected to the originating host (the x11vnc VNC Server.) SSL is
-   then layered over this socket.
-
-   To do this you should use the proxy.vnc HTML file like via this URL in
-   your browser:
-  https://yourmachine.com:5900/proxy.vnc
-
-   (instead of the unsigned one in https://yourmachine.com:5900/ that
-   gives the default index.vnc)
-
-   Proxies that limit CONNECT to ports 443 and 563:
-
-   Things become trickier if the Web proxy restricts which CONNECT ports
-   can be redirected to. For security, some (most?) proxies only allow
-   port 443 (HTTPS) and 563 (SNEWS) by default. In this case, the only
-   thing to do is run x11vnc on that low port, e.g. "-rfbport 443", (or
-   use a port redirection on, say, a firewall or router port 443 to the
-   internal machine.)
-
-   If you do such a redirection to an internal machine and x11vnc is not
-   listening on port 443, you will probably need to edit proxy.vnc.
-   Suppose the SSL x11vnc server was listening on port 5901. You should
-   change the line in proxy.vnc from:
-  <param name=PORT value=$PORT>
-
-   to:
-  <param name=PORT value=443>
-
-   Since otherwise $PORT will be expanded to 5901 by x11vnc and the
-   viewer applet will fail to connect to that port on the firewall.
-
-   Another way to achieve the same thing is to use the applet PORT
-   parameter:
-  https://yourmachine.com/proxy.vnc?PORT=443
-
-   this is cleaner because it avoids editing the file, but requires more
-   parameters in the URL. See also the -httpsredir x11vnc option that
-   will try to automate this for you. To use the GET trick discussed
-   above, do:
-  https://yourmachine.com/proxy.vnc?GET=1&PORT=443
-
-   All of the x11vnc Java Viewer applet parameters are described in the
-   file classes/ssl/README
-
-   Here is an example of Java Console and x11vnc output for the Web proxy
-   case.
-
-
-   Note that both the ss_vncviewer stunnel Unix wrapper script and
-   Enhanced TightVNC Viewer (SSVNC) can use Web proxies as well even
-   though they do not involve a Web browser.
-
-
-   Q-56: Can Apache web server act as a gateway for users to connect via
-   SSL from the Internet with a Web browser to x11vnc running on their
-   workstations behind a firewall?
-   Yes. You will need to configure apache to forward these connections.
-   It is discussed here. This SSL VNC portal provides a clean alternative
-   to the traditional method where the user uses SSH to log in through
-   the gateway to create the encrypted port redirection to x11vnc running
-   on her desktop.
-
-   Also see the desktop.cgi CGI script method that achieves much of what
-   this Apache VNC SSL portal method does (as long as desktop.cgi's 'port
-   redirection' mode is enabled.)
-
-
-   Q-57: Can I create and use my own SSL Certificate Authority (CA) with
-   x11vnc?
-   Yes, see this page for how to do this and the utility commands x11vnc
-   provides to create and manage many types of certificates and private
-   keys.
-
-
-
-   [Display Managers and Services]
-
-   Q-58: How can I run x11vnc as a "service" that is always available?
-
-   There are a number of ways to do this. The primary thing you need to
-   decide is whether you want x11vnc to connect to the X session on the
-   machine 1) regardless of who (or if anyone) has the X session, or 2)
-   only if a certain user has the X session. Because X sessions are
-   protected by X permissions (MIT-MAGIC-COOKIE files XAUTHORITY and
-   $HOME/.Xauthority) the automatically started x11vnc will of course
-   need to have sufficient permissions to connect to the X display.
-
-   Here are some ideas:
-     * Use the description under "Continuously" in the FAQ on x11vnc and
-       Display Managers
-     * Use the description in the FAQ on x11vnc and inetd(8)
-     * Use the description in the FAQ on Unix user logins and inetd(8)
-     * Start x11vnc from your $HOME/.xsession (or $HOME/.xinitrc or
-       autostart script or ...)
-     * Although less reliable, see the x11vnc_loop rc.local hack below.
-
-   The display manager scheme will not be specific to which user has the
-   X session unless a test is specifically put into the display startup
-   script (often named Xsetup.) The inetd(8) scheme may or may not be
-   specific to which user has the X session (and it may not be able to do
-   all users via the XAUTHORITY permission issues.)
-
-   The .xsession/.xinitrc scheme is obviously is specific to a particular
-   user and only when they are logged into X. If you do not know what a
-   $HOME/.xsession script is or how to use one, perhaps your desktop has
-   a "session startup commands" configuration option. The command to be
-   run in the .xsession or .xinitrc file may look like this:
-x11vnc -logfile $HOME/.x11vnc.log -rfbauth $HOME/.vnc/passwd -forever -bg
-
-   plus any other options you desire.
-
-   Depending on your desktop and/or OS/distribution the automatically run
-   X startup scripts (traditionally .xsession/.xinitrc) may have to be in
-   a different directory or have a different basename. One user
-   recommends the description under 'Running Scripts Automatically' at
-   this link.
-
-   Firewalls: note all methods will require the host-level firewall to be
-   configured to allow connections in on a port. E.g. 5900 (default VNC
-   port) or 22 (default SSH port for tunnelling VNC.) Most systems these
-   days have firewalls turned on by default, so you will actively have to
-   do something to poke a hole in the firewall at the desired port
-   number. See your system administration tool for Firewall settings
-   (Yast, Firestarter, etc.)
-
-
-   Q-59: How can I use x11vnc to connect to an X login screen like xdm,
-   GNOME gdm, KDE kdm, or CDE dtlogin? (i.e. nobody is logged into an X
-   session yet.)
-
-   We describe two scenarios here. The first is called 'One time only'
-   meaning you just need to do it quickly once and don't want to repeat;
-   and the second is called 'Continuously' meaning you want the access to
-   be available after every reboot and after every desktop logout.

-   One time only:   If the X login screen is running and you just want to
-   connect to it once (i.e. a one-shot):
-
-   It is usually possible to do this by just adjusting the XAUTHORITY
-   environment variable to point to the correct MIT-COOKIE auth file
-   while running x11vnc as root, e.g. for the gnome display manager, GDM:
-  x11vnc -auth /var/gdm/:0.Xauth -display :0
-
-   (the -auth option sets the XAUTHORITY variable for you.)
-
-   There will be a similar thing to do for xdm using however a different
-   auth directory path (perhaps something like
-   /var/lib/xdm/authdir/authfiles/A:0-XQvaJk) for the xdm greeter or
-   /var/lib/kdm/A:0-crWk72 (or /var/run/xauth/A:0-qQPftr, etc. etc) for
-   the kdm greeter. Of course, the random characters in the file basename
-   will vary and you will need to use the actual filename on your system.
-   Read your system docs to find out where the display manager cookie
-   files are kept.
-
-   Trick: sometimes ps(1) can reveal the X server process -auth argument
-   (e.g. "ps wwaux | grep auth") and hence the path to the auth file.
-
-   x11vnc must be run as root for this because the /var/gdm/:0.Xauth,
-   /var/lib/kdm/A:0-crWk72, etc. auth files are only readable by root. If
-   you do not want to run x11vnc as root, you can copy (as root or sudo)
-   the auth file to some location and make it readable by your userid.
-   Then run x11vnc as your userid with -auth pointed to the copied file.
-
-   Update Dec/2009: use "-auth guess" to have x11vnc try to guess the
-   location of the auth file for you.
-
-   You next connect to x11vnc with a VNC viewer, give your username and
-   password to the X login prompt to start your session.
-
-   Note:  GDM: gdm seems to have an annoying setting that causes x11vnc
-   (and any other X clients) to be killed after the user logs in. Setting
-   KillInitClients=false in the [daemon] section of /etc/X11/gdm/gdm.conf
-   (or /etc/gdm/gdm.conf, etc.) avoids this. Otherwise, just restart
-   x11vnc and then reconnect your viewer. Other display managers (kdm,
-   etc) may also have a similar problem. One user reports having to alter
-   "gdm.conf-custom" as well.
-
-   Note:  Solaris: For dtlogin in addition to the above sort of trick
-   (BTW, the auth file should be in /var/dt), you'll also need to add
-   something like Dtlogin*grabServer:False to the Xconfig file
-   (/etc/dt/config/Xconfig or /usr/dt/config/Xconfig on Solaris, see the
-   example at the end of this FAQ.) Then restart dtlogin, e.g.:
-   /etc/init.d/dtlogin stop; /etc/init.d/dtlogin start or reboot.
-
-   Update Nov/2008: Regarding GDM KillInitClients: see the -reopen option
-   for another possible workaround.
-
-   Update Oct/2009: Regarding GDM KillInitClients: starting with x11vnc
-   0.9.9 it will try to apply heuristics to detect if a window manager is
-   not running (i.e. whether the Display Manager Greeter Login panel is
-   still up.) If it thinks the display manager login is still up it will
-   delay creating windows or using XFIXES. The former is what GDM uses to
-   kill the initial clients, use of the latter can cause a different
-   problem: an Xorg server crash. So with 0.9.9 and later it should all
-   work without needing to set KillInitClients=false (which is a good
-   because recent GDM, v2.24, has removed this option) or use -noxfixes.
-   To disable the heuristics and delaying set X11VNC_AVOID_WINDOWS=never;
-   to set the delay time explicitly use, e.g., X11VNC_AVOID_WINDOWS=120
-   (delays for 120 seconds after the VNC connection; you have that long
-   to log in.)
-     _________________________________________________________________
-
-   Continuously:   Have x11vnc reattach each time the X server is
-   restarted (i.e. after each logout and reboot):
-
-   To make x11vnc always attached to the X server including the login
-   screen you will need to add a command to a display manager startup
-   script.
-
-   Please consider the security implications of this! The VNC display for
-   the X session always accessible (but hopefully password protected.)
-   Add -localhost if you only plan to access via a SSH tunnel.
-
-   The name of the display manager startup script file depends on desktop
-   used and seem to be:
-     GDM (GNOME)  /etc/X11/gdm/Init/Default
-                  /etc/gdm/Init/Default
-     KDM (KDE)    /etc/kde*/kdm/Xsetup
-     XDM          /etc/X11/xdm/Xsetup          (or sometimes xdm/Xsetup_0)
-     CDE          /etc/dt/config/Xsetup
-
-   although the exact location can be operating system, distribution, and
-   time dependent. See the documentation for your display manager:
-   gdm(1), kdm(1), xdm(1), dtlogin(1) for additional details. There may
-   also be display number specific scripts: e.g. Xsetup_0 vs. Xsetup, you
-   need to watch out for.
-
-   Note:  You should read and understand all of the Note's and Update's
-   in the 'One time only' section above. All of the GDM topics apply here
-   as well:
-
-   Note:  GDM: The above (in 'One time only') gdm setting of
-   KillInitClients=false in /etc/X11/gdm/gdm.conf (or /etc/gdm/gdm.conf,
-   etc.) for GDM is needed here as well. Other display managers (KDM,
-   etc) may also have a similar problem.
-
-   Also see the Update Oct/2009 above where x11vnc 0.9.9 and later
-   automatically avoids being killed.
-
-   Note:  DtLogin: The above (in 'One time only')
-   Dtlogin*grabServer:False step for Solaris will be needed for dtlogin
-   here as well.
-
-   In any event, the line you will add to the display manager script
-   (Xsetup, Default, or whatever) will look something like:
-  /usr/local/bin/x11vnc -rfbauth /path/to/the/vnc/passwd -o /var/log/x11vnc.log
- -forever -bg
-
-   where you should customize the exact command to your needs (e.g.
-   -localhost for SSH tunnel-only access; -ssl SAVE for SSL access; etc.)
-
-   Happy, happy, joy, joy:  Note that we do not need to specify -display
-   or -auth because happily they are already set for us in the DISPLAY
-   and XAUTHORITY environment variables for the Xsetup script!!!
-
-   You may also want to force the VNC port with something like "-rfbport
-   5900" (or -N) to avoid autoselecting one if 5900 is already taken.

-
-   Fedora/gdm: Here is an example of what we did on a vanilla install of
-   Fedora-C3 (seems to use gdm by default.) Add a line like this to
-   /etc/X11/gdm/Init/:0
-  /usr/local/bin/x11vnc -rfbauth /etc/x11vnc.passwd -forever -bg -o /var/log/x1
-1vnc.log
-
-   And then add this line to /etc/X11/gdm/gdm.conf (or /etc/gdm/gdm.conf,
-   etc.) in the [daemon] section:
-  KillInitClients=false
-
-   Then restart: /usr/sbin/gdm-restart (or reboot.) The
-   KillInitClients=false setting is important: without it x11vnc will be
-   killed immediately after the user logs in. Here are full details on
-   how to configure gdm
-     _________________________________________________________________
-
-   Solaris/dtlogin: Here is an example of what we did on a vanilla
-   install of Solaris:
-   Make the directory /etc/dt/config:
-  mkdir -p /etc/dt/config
-
-   Copy over the Xconfig file for customization:
-  cp /usr/dt/config/Xconfig /etc/dt/config/Xconfig
-
-   Edit /etc/dt/config/Xconfig and uncomment the line:
-  Dtlogin*grabServer:        False
-
-   Next, copy over Xsetup for customization:
-  cp /usr/dt/config/Xsetup /etc/dt/config/Xsetup
-
-   Edit /etc/dt/config/Xsetup and at the bottom put a line like:
-  /usr/local/bin/x11vnc -forever -o /var/log/x11vnc.log -bg
-
-   (tweaked to your local setup and preferences, a password via -rfbauth,
-   etc. would be a very good idea.)
-
-   Restart the X server and dtlogin:
-  /etc/init.d/dtlogin stop
-  /etc/init.d/dtlogin start
-
-   (or reboot or maybe just restart the X session.)
-     _________________________________________________________________
-
-   KDM: One user running the kdm display manager reports putting this
-   line:
-  x11vnc -forever -rfbauth /home/xyz/.vnc/passwd -bg -o /var/log/x11vnc.log
-
-   in /etc/kde/kdm/Xsetup. After rebooting the system it all seemed to
-   work fine.
-     _________________________________________________________________
-
-
-   If you do not want to deal with any display manager startup scripts,
-   here is a kludgey script that can be run manually or out of a boot
-   file like rc.local: x11vnc_loop It will need some local customization
-   before running. Because the XAUTHORITY auth file must be guessed by
-   this script, use of the display manager script method described above
-   is greatly preferred. There is also the -loop option that does
-   something similar.
-
-   If the machine is a traditional Xterminal you may want to read this
-   FAQ.
-
-   Firewalls: note all methods will require the host-level firewall to be
-   configured to allow connections in on a port. E.g. 5900 (default VNC
-   port) or 22 (default SSH port for tunnelling VNC.) Most systems these
-   days have firewalls turned on by default, so you will actively have to
-   do something to poke a hole in the firewall at the desired port
-   number. See your system administration tool for Firewall settings
-   (Yast, Firestarter, etc.)
-
-
-   Q-60: Can I run x11vnc out of inetd(8)? How about xinetd(8)?
-
-   Yes, perhaps a line something like this in /etc/inetd.conf will do it
-   for you:
-
-  5900 stream tcp nowait root /usr/sbin/tcpd /usr/local/bin/x11vnc_sh
-
-   where the shell script /usr/local/bin/x11vnc_sh uses the -inetd option
-   and looks something like (you'll need to customize to your settings.)
-#!/bin/sh
-/usr/local/bin/x11vnc -inetd -display :0 -auth /home/fred/.Xauthority \
-        -rfbauth /home/fred/.vnc/passwd -o /var/log/x11vnc_sh.log
-
-   Important:  Note that you must redirect the standard error output to a
-   log file (e.g. -o logfile) or "2>/dev/null" for proper operation via
-   inetd (otherwise the standard error also goes to the VNC vncviewer,
-   and that confuses it greatly, causing it to abort.) If you do not use
-   a wrapper script as above but rather call x11vnc directly in
-   /etc/inetd.conf and do not redirect stderr to a file, then you must
-   specify the -q (aka -quiet) option: "/usr/local/bin/x11vnc -q -inetd
-   ...". When you supply both -q and -inet and no "-o logfile" then
-   stderr will automatically be closed (to prevent, e.g. library stderr
-   messages leaking out to the viewer.) The recommended practice is to
-   use "-o logfile" to collect the output in a file or wrapper script
-   with "2>logfile" redirection because the errors and warnings printed
-   out are very useful in troubleshooting problems.
-
-   Note also the need to set XAUTHORITY via -auth to point to the
-   MIT-COOKIE auth file to get permission to connect to the X display
-   (setting and exporting the XAUTHORITY variable accomplishes the same
-   thing.) See the x11vnc_loop file in the previous question for more
-   ideas on what that auth file may be, etc. The scheme described in the
-   FAQ on Unix user logins and inetd(8) works around the XAUTHORITY issue
-   nicely.
-
-   Note:  On Solaris you cannot have the bare number 5900 in
-   /etc/inetd.conf, you'll need to replace it with a word like x11vnc an
-   then put something like "x11vnc 5900/tcp" in /etc/services.
-
-   Since the process runs as root, it might be a bad idea to have the
-   logfile in a world-writable area like /tmp if there are untrustworthy
-   users on the machine. Perhaps /var/log is a better place.
-
-   Be sure to look at your /etc/hosts.allow and /etc/hosts.deny settings
-   to limit the machines that can connect to this service (your desktop!)
-   For the above example with /etc/hosts.allow:
-  x11vnc_sh : 123.45.67.89
-
-   A really safe way to do things is to limit the above inetd to
-   localhost only (via /etc/hosts.allow) and use ssh to tunnel the
-   incoming connection. Using inetd for this prevents there being a tiny
-   window of opportunity between x11vnc starting up and your vncviewer
-   connecting to it. Always use a VNC password to further protect against
-   unwanted access.
-
-   For xinetd(8), one user reports he created the file
-   /etc/xinetd.d/x11vncservice containing the following:
-# default: off
-# description:
-service x11vncservice
-{
-        flags           = REUSE NAMEINARGS
-        port            = 5900
-        type            = UNLISTED
-        socket_type     = stream
-        protocol        = tcp
-        wait            = no
-        user            = root
-        server          = /usr/sbin/tcpd
-        server_args     = /usr/local/bin/x11vnc_sh
-        disable         = no
-}
-
-   With the contents of /usr/local/bin/x11vnc_sh similar to the example
-   given above. One user reports this works with avoiding the wrapper
-   script:
-service x11vncservice
-{
-        port            = 5900
-        type            = UNLISTED
-        socket_type     = stream
-        protocol        = tcp
-        wait            = no
-        user            = root
-        server          = /usr/local/bin/x11vnc
-        server_args     = -inetd -q -display :0 -auth /var/gdm/:0.Xauth
-        disable         = no
-}
-
-   (or one can replace the -q with say "-o /var/log/x11vnc.log" to
-   capture a log)
-
-   The above works nicely for GDM because the -auth file is a fixed name.
-   For KDM or XDM the filename varies. Here is one idea for a x11vnc_sh
-   wrapper to try to guess the name:
-#!/bin/sh
-COLUMNS=256
-export COLUMNS
-authfile=`ps wwaux | grep '/X.*-auth' | grep -v grep | sed -e 's/^.*-auth *//'
--e 's/ .*$//' | head -n 1`
-
-if [ -r "$authfile" ]; then
-        exec /usr/local/bin/x11vnc -inetd -o /var/log/x11vnc.log -display :0 -a
-uth "$authfile"
-fi
-exit 1
-
-   Starting with x11vnc 0.9.3 this can be automated by:
-#!/bin/sh
-exec /usr/local/bin/x11vnc -inetd -o /var/log/x11vnc.log -find -env FD_XDM=1
-
-
-   Q-61: Can I have x11vnc advertise its VNC service and port via mDNS /
-   Zeroconf (e.g. Avahi) so VNC viewers on the local network can detect
-   it automatically?
-
-   Yes, as of Feb/2007 x11vnc supports mDNS / Zeroconf advertising of its
-   service via the Avahi client library. Use the option -avahi (same as
-   -mdns or -zeroconf) to enable it. Depending on your setup you may need
-   to install Avahi (including the development/build packages), enable
-   the server: avahi-daemon and avahi-dnsconfd, and possibly open up UDP
-   port 5353 on your firewall.
-
-   If the Avahi client library or build environment is not available at
-   build-time, then at run-time x11vnc will try to look for external
-   helper programs, avahi-browse(1) or dns-sd(1), to do the work.
-
-   The service was tested with Chicken of the VNC ("Use Bonjour"
-   selected) on a Mac on the same network and the service was noted and
-   listed in the servers list. Clicking on it and then "Connect"
-   connected automatically w/o having to enter any hostnames or port
-   numbers.
-
-   It appears SuSE 10.1 comes with avahi (or you can add packages, e.g.
-   avahi-0.6.5-27) but not the development package (you can use the
-   OpenSuSE avahi-devel rpm.) Unfortunately, you may need to disable
-   another Zeroconf daemon "/etc/init.d/mdnsd stop", before doing
-   "/etc/init.d/avahi-daemon start" and "/etc/init.d/avahi-dnsconfd
-   start". We also had to comment out the browse-domains line in
-   /etc/avahi/avahi-daemon.conf. Hopefully there is "LessConf" to do on
-   other distros/OS's...
-
-
-   Q-62: Can I have x11vnc allow a user to log in with her UNIX username
-   and password and then have it find her X session display on that
-   machine and then attach to it? How about starting an X session if one
-   cannot be found?
-
-   The easiest way to do this is via inetd(8) using the -unixpw and
-   -display WAIT options. The reason inetd(8) makes this easier is that
-   it starts a new x11vnc process for each new user connection. Otherwise
-   a wrapper would have to listen for connections and spawn new x11vnc's
-   (see this example and also the -loopbg option.) inetd(8) is not
-   required for this, but it makes some aspects more general.
-
-   Also with inetd(8) users always connect to a fixed VNC display, say
-   hostname:0, and do not need to memorize a special VNC display number
-   just for their personal use, etc.
-
-   Update: Use the -find, -create, -svc, and -xdmsvc options that are
-   shorthand for common FINDCREATEDISPLAY usage modes (e.g. terminal
-   services) described below. (i.e. simply use "-svc" instead of the
-   cumbersome "-display WAIT:cmd=FINDCREATEDISPLAY-Xvfb -unixpw -users
-   unixpw= -ssl SAVE")
-
-   The -display WAIT option makes x11vnc wait until a VNC viewer is
-   connected before attaching to the X display.
-
-   Additionally it can be used to run an external command that returns
-   the DISPLAY and XAUTHORITY data. We provide some useful builtin ones
-   (FINDDISPLAY and FINDCREATEDISPLAY below), but in principle one could
-   supply his own script: "-display WAIT:cmd=/path/to/find_display" where
-   the script find_display might look something like this.
-
-   A default script somewhat like the above is used under "-display
-   WAIT:cmd=FINDDISPLAY" (same as -find) The format for any such command
-   is that it returns DISPLAY=:disp as the first line and any remaining
-   lines are either XAUTHORITY=file or raw xauth data (the above example
-   does the latter.) If applicable (-unixpw mode), the program is run as
-   the Unix user name who logged in.
-
-   On Linux if the virtual terminal is known the program appends ",VT=n"
-   to the DISPLAY line; a chvt n will be attempted automatically. Or if
-   only the X server process ID is known it appends ",XPID=n" (a chvt
-   will be attempted by x11vnc.)
-
-   Tip: Note that the -find option is an alias for "-display
-   WAIT:cmd=FINDDISPLAY". Use it!
-
-   The -unixpw option allows UNIX password logins. It conveniently knows
-   the Unix username whose X display should be found. Here are a couple
-   /etc/inetd.conf examples of this usage:
-5900  stream  tcp  nowait  nobody  /usr/sbin/tcpd /usr/local/bin/x11vnc -inetd
--unixpw \
-      -find -o /var/log/x11vnc.log -ssl SAVE -ssldir /usr/local/certs
-5900  stream  tcp  nowait  root    /usr/sbin/tcpd /usr/local/bin/x11vnc -inetd
--unixpw \
-      -find -o /var/log/x11vnc.log -ssl SAVE -users unixpw=
-
-   Note we have used the -find alias and the very long lines have been
-   split. An alternative is to use a wrapper script, e.g.
-   /usr/local/bin/x11vnc.sh that has all of the options. (see also the
-   -svc alias.)
-
-   In the first inetd line x11vnc is run as user "nobody" and stays user
-   nobody during the whole session. The permissions of the log files and
-   certs directory will need to be set up to allow "nobody" to use them.
-
-   In the second one x11vnc is run as root and switches to the user that
-   logs in due to the "-users unixpw=" option.
-
-   Note that SSL is required for this mode because otherwise the Unix
-   password would be passed in clear text over the network. In general
-   -unixpw is not required for this sort of scheme, but it is convenient
-   because it determines exactly who the Unix user is whose display
-   should be sought. Otherwise the find_display script would have to use
-   some method to work out DISPLAY, XAUTHORITY, etc (perhaps you use
-   multiple inetd ports and hardwire usernames for different ports.)
-
-   If you really want to disable the SSL or SSH -localhost constraints
-   (this is not recommended unless you really know what you are doing:
-   Unix passwords sent in clear text is a very bad idea...) read the
-   -unixpw documentation.
-
-   A inetd(8) scheme for a fixed user that doesn't use SSL or unix
-   passwds could be:
-  /usr/local/bin/x11vnc -inetd -users =fred -find -rfbauth /home/fred/.vnc/pass
-wd -o /var/log/x11vnc.log
-
-   The "-users =fred" option will cause x11vnc to switch to user fred and
-   then find his X display. The VNC password (-rfbauth) as opposed to
-   Unix password (-unixpw) is used to authenticate the VNC client.
-
-   Similar looking commands to the above examples can be run directly and
-   do not use inetd (just remove the -inetd option and run from the
-   cmdline, etc.)
-
-
-   X Session Creation: An added (Nov/2006) extension to FINDDISPLAY is
-   FINDCREATEDISPLAY where if it does not find an X display via the
-   FINDDISPLAY method it will create an X server session for the user
-   (i.e. desktop/terminal server.) This is the only time x11vnc actually
-   tries to start up an X server (normally it just attaches to an
-   existing one.)
-
-   For virtual sessions you will need to install the Xvfb program (e.g.
-   apt-get install xvfb) or our Xdummy program (see below.)
-
-   By default it will only try to start up virtual (non-hardware) X
-   servers: first Xvfb and if that is not available then Xdummy (included
-   in the x11vnc source code.) Note that Xdummy only works on Linux
-   whereas Xvfb works just about everywhere (and in some situations
-   Xdummy must be run as root.) An advantage of Xdummy over Xvfb is that
-   Xdummy supports RANDR dynamic screen resizing, which can be handy if
-   the user accesses the desktop from different sized screens (e.g.
-   workstation and laptop.)
-
-   So an inetd(8) example might look like:
-5900 stream tcp nowait root /usr/sbin/tcpd /usr/local/bin/x11vnc -inetd \
-      -o /var/log/x11vnc.log -http -prog /usr/local/bin/x11vnc \
-      -ssl SAVE -unixpw -users unixpw= -display WAIT:cmd=FINDCREATEDISPLAY
-
-   Where the very long lines have been split. See below where that long
-   and cumbersome last line is replaced by the -svc alias.
-
-   The above mode will allow direct SSL (e.g. ss_vncviewer or SSVNC)
-   access and also Java Web browers access via: https://hostname:5900/.
-
-   Tip: Note that the -create option is an alias for "-display
-   WAIT:cmd=FINDCREATEDISPLAY-Xvfb".
-
-   Tip: Note that -svc is a short hand for the long "-ssl SAVE -unixpw
-   -users unixpw= -display WAIT:cmd=FINDCREATEDISPLAY" part. Unlike
-   -create, this alias also sets up SSL encryption and Unix password
-   login.
-
-   The above inetd example then simplifies to:
-5900 stream tcp nowait root /usr/sbin/tcpd /usr/local/bin/x11vnc -inetd \
-      -o /var/log/x11vnc.log -http -prog /usr/local/bin/x11vnc \
-      -svc
-
-   Tip: In addition to the usual unixpw parameters, inside the VNC viewer
-   the user can specify after his username (following a ":" see -display
-   WAIT for details) for FINDCREATEDISPLAY they can add "geom=WxH" or
-   "geom=WxHxD" to specify the width, height, and optionally the color
-   depth. E.g. "fred:geom=800x600" at the login: prompt. Also if the env.
-   var X11VNC_CREATE_GEOM is set to the desired WxH or WxHxD that will be
-   used by x11vnc.
-
-   You can set the env. var X11VNC_SKIP_DISPLAY to a comma separated list
-   of displays to ignore in the FINDDISPLAY process (to force creation of
-   new displays in some cases.) The user logging in via the vncviewer can
-   also set this via username:nodisplay=...)
-
-   If you do not plan on using the Java Web browser applet you can remove
-   the -http (and -prog) option since this will speed up logging-in by a
-   few seconds (x11vnc will not have to wait to see if a connection is
-   HTTPS or VNC.)
-
-   For reference, xinetd format in the file, say, /etc/xinetd.d/x11vnc:
-service x11vnc
-{
-        type            = UNLISTED
-        port            = 5900
-        socket_type     = stream
-        protocol        = tcp
-        wait            = no
-        user            = root
-        server          = /usr/local/bin/x11vnc
-        server_args     = -inetd -o /var/log/x11vnc.log -http -prog /usr/local/
-bin/x11vnc -svc
-        disable         = no
-}
-
-   To print out the script in this case use "-display
-   WAIT:cmd=FINDCREATEDISPLAY-print". To change the preference of
-   Xservers and which to try list them, e.g.: "-display
-   WAIT:cmd=FINDCREATEDISPLAY-X,Xvfb,Xdummy" or use "-create_xsrv
-   X,Xvfb,Xdummy". The "X" one means to try to start up a real, hardware
-   X server, e.g. startx(1) (if there is already a real X server running
-   this may only work on Linux and the chvt program may need to be run to
-   switch to the correct Linux virtual terminal.) x11vnc will try to run
-   chvt automatically if it can determine which VT should be switched to.
-
-   XDM/GDM/KDM Login Greeter Panel: If you want to present the user with
-   a xdm/gdm/kdm display manager "greeter" login you can use Xvfb.xdmcp
-   instead of Xvfb, etc in the above list. However, you need to configure
-   xdm/gdm/kdm to accept localhost XDMCP messages, this can be done by
-   (from -help output):
-      If you want the FINDCREATEDISPLAY session to contact an XDMCP login
-      manager (xdm/gdm/kdm) on the same machine, then use "Xvfb.xdmcp"
-      instead of "Xvfb", etc.  The user will have to supply his username
-      and password one more time (but he gets to select his desktop
-      type so that can be useful.)  For this to work, you will need to
-      enable localhost XDMCP (udp port 177) for the display manager.
-      This seems to be:
-
-       for gdm in gdm.conf:   Enable=true in section [xdmcp]
-       for kdm in kdmrc:      Enable=true in section [Xdmcp]
-       for xdm in xdm-config: DisplayManager.requestPort: 177
-
-   Unless you are also providing XDMCP service to xterminals or other
-   machines, make sure that the host access list only allows local
-   connections (the name of this file is often Xaccess and it is usually
-   setup by default to do just that.) Nowadays, host level firewalling
-   will also typically block UDP (port 177 for XDMCP) by default
-   effectively limiting the UDP connections to localhost.
-
-   Tip: Note that -xdmsvc is a short hand alias for the long "-ssl SAVE
-   -unixpw -users unixpw= -display
-   WAIT:cmd=FINDCREATEDISPLAY-Xvfb.xdmcp". So we simply use:
-service x11vnc
-{
-        type            = UNLISTED
-        port            = 5900
-        socket_type     = stream
-        protocol        = tcp
-        wait            = no
-        user            = root
-        server          = /usr/local/bin/x11vnc
-        server_args     = -inetd -o /var/log/x11vnc.log -xdmsvc
-        disable         = no
-}
-
-   (Note: use "-svc" instead of "-xdmsvc" for no XDMCP login greeter.)
-
-
-   Local access (VNC Server and VNC Viewer on the same machine): To
-   access your virtual X display session locally (i.e. while sitting at
-   the same machine it is running on) one can perhaps have something like
-   this in their $HOME/.xinitrc
-#!/bin/sh
-x11vnc -create -rfbport 5905 -env WAITBG=1
-vncviewer -geometry +0+0 -encodings raw -passwd $HOME/.vnc/passwd localhost:5
-
-   You may not need the -passwd. Recent RealVNC viewers might be this:
-#!/bin/sh
-x11vnc -create -rfbport 5905 -env WAITBG=1
-vncviewer -FullScreen -PreferredEncoding raw -passwd $HOME/.vnc/passwd localhos
-t:5
-
-   This way a bare X server is run with no window manager or desktop; it
-   simply runs only the VNC Viewer on the real X server. The Viewer then
-   draws the virtual X session on to the real one. On your system it
-   might not be $HOME/.xinitrc, but rather .xsession, .Xclients, or
-   something else. You will need to figure out what it is for your system
-   and configuration.
-
-   There may be a problem if the resolution (WxH) of the virtual X
-   display does not match that of the physical X display.
-
-   If you do not want to or cannot figure out the X startup script name
-   (.xinitrc, etc) you could save the above commands to a shell script,
-   say "vnclocal", and the log in via the normal KDM or GDM greeter
-   program using the "Failsafe" option. Then in the lone xterm that comes
-   up type "vnclocal" to connect to your virtual X display via x11vnc and
-   vncviewer.
-
-     _________________________________________________________________
-
-   Summary: The "-display WAIT:cmd=FINDCREATEDISPLAY" scheme can be used
-   to provide a "desktop service" (i.e. terminal service) on the server
-   machine: you always get some desktop there, either a real hardware X
-   server or a virtual one (depending on how you set things up.)
-
-   So it provides simple "terminal services" based on Unix username and
-   password. The created X server sessions (virtual or real hardware)
-   will remain running after you disconnect the VNC viewer and will be
-   found again on reconnecting via VNC and logging in. To terminate them
-   use the normal way to Exit/LogOut from inside your X session. The user
-   does not have to memorize which VNC display number is his. They all go
-   the same one (e.g. hostname:0) and it switches based on username.
-
-
-   Q-63: Can I have x11vnc restart itself after it terminates?
-
-   One could do this in a shell script, but now there is an option -loop
-   that makes it easier. Of course when x11vnc restarts it needs to have
-   permissions to connect to the (potentially new) X display. This mode
-   could be useful if the X server restarts often. Use e.g. "-loop5000"
-   to sleep 5000 ms between restarts. Also "-loop2000,5" to sleep 2000 ms
-   and only restart 5 times.
-
-   One can also use the -loopbg to emulate inetd(8) to some degree, where
-   each connected process runs in the background. It could be combined,
-   say, with the -svc option to provide simple terminal services without
-   using inetd(8).
-
-
-   Q-64: How do I make x11vnc work with the Java VNC viewer applet in a
-   web browser?
-
-   To have x11vnc serve up a Java VNC viewer applet to any web browsers
-   that connect to it, run x11vnc with this option:
-  -httpdir /path/to/the/java/classes/dir
-
-   (this directory will contain the files index.vnc and, for example,
-   VncViewer.jar) Note that libvncserver contains the TightVNC Java
-   classes jar file for your convenience. (it is the file
-   classes/VncViewer.jar in the source tree.)
-
-   You will see output something like this:
-  14/05/2004 11:13:56 Autoprobing selected port 5900
-  14/05/2004 11:13:56 Listening for HTTP connections on TCP port 5800
-  14/05/2004 11:13:56   URL http://walnut:5800
-  14/05/2004 11:13:56 screen setup finished.
-  14/05/2004 11:13:56 The VNC desktop is walnut:0
-  PORT=5900
-
-   then you can connect to that URL with any Java enabled browser. Feel
-   free to customize the default index.vnc file in the classes directory.
-
-   As of May/2005 the -http option will try to guess where the Java
-   classes jar file is by looking in expected locations and ones relative
-   to the x11vnc binary.
-
-   Also note that if you wanted to, you could also start the Java viewer
-   entirely from the viewer-side by having the jar file there and using
-   either the java or appletviewer commands to run the program.
-  java -cp ./VncViewer.jar VncViewer HOST far-away.east PORT 5900
-
-   Proxies: See the discussion here if the web browser must use a web
-   proxy to connect to the internet. It is tricky to get Java applets to
-   work in this case: a signed applet must be used so it can connect to
-   the proxy and ask for the redirection to the VNC server. One way to do
-   this is to use the signed SSL one referred to in classes/ssl/proxy.vnc
-   and set disableSSL=yes (note that this has no encryption; please use
-   SSL or SSH as discuss elsewhere on this page) in the URL or the file.
-
-
-   Q-65: Are reverse connections (i.e. the VNC server connecting to the
-   VNC viewer) using "vncviewer -listen" and vncconnect(1) supported?
-
-   As of Mar/2004 x11vnc supports reverse connections. On Unix one starts
-   the VNC viewer in listen mode: "vncviewer -listen" (see your
-   documentation for Windows, etc), and then starts up x11vnc with the
-   -connect option. To connect immediately at x11vnc startup time use the
-   "-connect host:port" option (use commas for a list of hosts to connect
-   to.) The ":port" is optional (default is VNC listening port is 5500.)
-
-   If a file is specified instead: -connect /path/to/some/file then that
-   file is checked periodically (about once a second) for new hosts to
-   connect to.
-
-   The -remote control option (aka -R) can also be used to do this during
-   an active x11vnc session, e.g.:
-x11vnc -display :0 -R connect:hostname.domain
-
-   Use the "-connect_or_exit" option to have x11vnc exit if the reverse
-   connection fails. Also, note the "-rfbport 0" option disables TCP
-   listening for connections (potentially useful for reverse connection
-   mode, assuming you do not want any "forward" connections.)
-
-   Note that as of Mar/2006 x11vnc requires password authentication for
-   reverse connections as well as for forward ones (assuming password
-   auth has been enabled, e.g. via -rfbauth, -passwdfile, etc.) Many VNC
-   servers do not require any password for reverse connections. To regain
-   the old behavior supply this option "-env
-   X11VNC_REVERSE_CONNECTION_NO_AUTH=1" to x11vnc.
-
-   Vncconnect command: To use the vncconnect(1) program (from the core
-   VNC package at www.realvnc.com) specify the -vncconnect option to
-   x11vnc (Note: as of Dec/2004 -vncconnect is now the default.)
-   vncconnect(1) must be pointed to the same X11 DISPLAY as x11vnc (since
-   it uses X properties to communicate with x11vnc.) If you do not have
-   or do not want to get the vncconnect(1) program, the following script
-   (named "Vncconnect") may work if your xprop(1) supports the -set
-   option:
-#!/bin/sh
-# usage: Vncconnect <host>
-#        Vncconnect <host:port>
-# note: not all xprop(1) support -set.
-#
-xprop -root -f VNC_CONNECT 8s -set VNC_CONNECT "$1"
-
-
-   Q-66: Can reverse connections be made to go through a Web or SOCKS
-   proxy or SSH?
-
-   Yes, as of Oct/2007 x11vnc supports reverse connections through
-   proxies: use the "-proxy host:port" option. The default is to assume
-   the proxy is a Web proxy. Note that most Web proxies only allow proxy
-   destination connections to ports 443 (HTTPS) and 563 (SNEWS) and so
-   this might not be too useful unless the proxy has been modified
-   (AllowCONNECT apache setting) or the VNC viewer listens on one of
-   those ports (or the router does a port redir.) A web proxy may also be
-   specified via "-proxy http://host:port"
-
-   For SOCKS4 and SOCKS4a proxies use this format "-proxy
-   socks://host:port". If the reverse connection hostname is a numerical
-   IP or "localhost" then SOCKS4 (no host lookup) is used, otherwise
-   SOCKS4a will be used. For SOCKS5 (proxy will do lookup and many other
-   things) use "-proxy socks5://host:port". Note that the SSH builtin
-   SOCKS proxy "ssh -D port" only does SOCKS4 or SOCKS5, so use socks5://
-   for a ssh -D proxy.
-
-   The proxying works for both SSL encrypted and normal reverse
-   connections.
-
-   An experimental mode is "-proxy http://host:port/..." where the URL
-   (e.g. a CGI script) is retrieved via the GET method. See -proxy for
-   more info.
-
-   Another experimental mode is "-proxy ssh://user@host" in which case a
-   SSH tunnel is used for the proxying. See -proxy for more info.
-
-   Up to 3 proxies may be chained together by listing them by commas
-   e.g.: "-proxy http://host1:port1,socks5://host2:port2" in case one
-   needs to ricochet off of several machines to ultimately reach the
-   listening viewer.
-
-
-   Q-67: Can x11vnc provide a multi-user desktop web login service as an
-   Apache CGI or PHP script?
-   Yes. See the example script desktop.cgi for ideas. It is in the source
-   tree in the directory x11vnc/misc. It serves x11vnc's SSL enabled Java
-   Applet to the web browser with the correct connection information for
-   the user's virtual desktop (an Xvfb session via -create; be sure to
-   add the Xvfb package.) HTTPS/SSL enabled Apache should be used to
-   serve the script to avoid unix and vnc passwords from being sent in
-   cleartext and sniffed.
-
-   By default it uses a separate VNC port for each user desktop (either
-   by autoprobing in a range of ports or using a port based on the userid
-   number.) The web server's firewall must allow incoming connections to
-   these ports.
-
-   It is somewhat difficult to do all of this with x11vnc listening on a
-   single port, however there is also a 'fixed port' scheme described in
-   the script based on -loopbg that works fairly well (but more
-   experience is needed to see what problems contention for the same port
-   causes; however at worst one user may need to re-login.)
-
-   There is also an optional 'port redirection' mode for desktop.cgi that
-   allows redirection to other machines inside the firewall already
-   running SSL enabled VNC servers. This provides much of the
-   functionality as the SSL Portal and is easier to set up.
-
-
-   Q-68: Can I use x11vnc as a replacement for Xvnc? (i.e. not for a real
-   display, but for a virtual one I keep around.)
-
-   You can, but you would not be doing this for performance reasons (for
-   virtual X sessions via VNC, Xvnc should give the fastest response.)
-   You may want to do this because Xvnc is buggy and crashes, does not
-   support an X server extension you desire, or you want to take
-   advantage of one of x11vnc's unending number of options and features.
-
-   One way to achieve this is to have a Xvfb(1) virtual framebuffer X
-   server running in the background and have x11vnc attached to it.
-   Another method, faster and more accurate, is to use the "dummy" Device
-   Driver in XFree86/Xorg (see below.)
-
-   For these virtual sessions you will need to install the Xvfb program
-   (e.g. apt-get install xvfb) or our Xdummy program (see below.)
-
-   In either case, one can view this desktop both remotely and also
-   locally using vncviewer. Make sure vncviewer's "-encodings raw" is in
-   effect for local viewing (compression seems to slow things down
-   locally.) For local viewing you set up a "bare" window manager that
-   just starts up vncviewer and nothing else (See how below.)
-
-   Here is one way to start up Xvfb:
-  xinit -- /usr/bin/Xvfb :1 -cc 4 -screen 0 1024x768x16
-
-   This starts up a 16bpp virtual display. To export it via VNC use
-  x11vnc -display :1 ...
-
-   Then have the remote vncviewer attach to x11vnc's VNC display (e.g. :0
-   which is port 5900.)
-
-   The "-cc 4" Xvfb option is to force it to use a TrueColor visual
-   instead of DirectColor (this works around a recent bug in the Xorg
-   Xvfb server.)
-
-   One good thing about Xvfb is that the virtual framebuffer exists in
-   main memory (rather than in the video hardware), and so x11vnc can
-   "screen scrape" it very efficiently (more than, say, 100X faster than
-   normal video hardware.)
-
-   Update Nov/2006: See the FINDCREATEDISPLAY discussion of the "-display
-   WAIT:cmd=FINDDISPLAY" option where virtual (Xvfb or Xdummy, or even
-   real ones by changing an option) X servers are started automatically
-   for new users connecting. This provides a "desktop service" for the
-   machine. You either get your real X session or your virtual
-   (Xvfb/Xdummy) one whenever you connect to the machine (inetd(8) is a
-   nice way to provide this service.) The -find, -create, -svc, and
-   -xdmsvc aliases can also come in handy here.
-
-   There are some annoyances WRT Xvfb however. The default keyboard
-   mapping seems to be very poor. One should run x11vnc with -add_keysyms
-   option to have keysyms added automatically. Also, to add the Shift_R
-   and Control_R modifiers something like this is needed:
-#!/bin/sh
-xmodmap -e "keycode any = Shift_R"
-xmodmap -e "add Shift = Shift_L Shift_R"
-xmodmap -e "keycode any = Control_R"
-xmodmap -e "add Control = Control_L Control_R"
-xmodmap -e "keycode any = Alt_L"
-xmodmap -e "keycode any = Alt_R"
-xmodmap -e "keycode any = Meta_L"
-xmodmap -e "add Mod1 = Alt_L Alt_R Meta_L"
-
-   (note: these are applied automatically in the FINDCREATEDISPLAY mode
-   of x11vnc.) Perhaps the Xvfb options -xkbdb or -xkbmap could be used
-   to get a better default keyboard mapping...
-
-   Dummy Driver:  A user points out a faster and more accurate method is
-   to use the "dummy" Device Driver of XFree86/Xorg instead of Xvfb. He
-   uses this to create a persistent and resizable desktop accessible from
-   anywhere. In the Device Section of the config file set Driver "dummy".
-   You may also need to set VideoRam NNN to be large enough to hold the
-   framebuffer. The framebuffer is kept in main memory like Xvfb except
-   that the server code is closely correlated with the real XFree86/Xorg
-   Xserver unlike Xvfb.
-
-   The main drawback to this method (besides requiring extra
-   configuration and possibly root permission) is that it also does the
-   Linux Virtual Console/Terminal (VC/VT) switching even though it does
-   not need to (since it doesn't use a real framebuffer.) There are some
-   "dual headed" (actually multi-headed/multi-user) patches to the X
-   server that turn off the VT usage in the X server. Update: As of
-   Jul/2005 we have an LD_PRELOAD script Xdummy that allows you to use a
-   stock (i.e. unpatched) Xorg or XFree86 server with the "dummy" driver
-   and not have any VT switching problems! An advantage of Xdummy over
-   Xvfb is that Xdummy supports RANDR dynamic screen resizing.
-
-   The standard way to start the "dummy" driver would be:
-startx -- :1 -config /etc/X11/xorg.conf.dummy
-
-   where the file /etc/X11/xorg.conf.dummy has its Device Section
-   modified as described above. To use the LD_PRELOAD wrapper script:
-startx -- /path/to/Xdummy :1
-
-   An xdm(1) example is also provided.
-
-   In general, one can use these sorts of schemes to use x11vnc to export
-   other virtual X sessions, say Xnest or even Xvnc itself (useful for
-   testing x11vnc.)
-
-   Local access (VNC Server and VNC Viewer on the same machine): You use
-   a VNC viewer to access the display remotely; to access your virtual X
-   display locally (i.e. while sitting at the same machine it is running
-   on) one can perhaps have something like this in their $HOME/.xinitrc
-#!/bin/sh
-x11vnc -display :5 -rfbport 5905 -bg
-vncviewer -geometry +0+0 -encodings raw -passwd $HOME/.vnc/passwd localhost:5
-
-   The display numbers (VNC and X) will likely be different (you could
-   also try -find), and you may not need the -passwd. Recent RealVNC
-   viewers might be this:
-#!/bin/sh
-x11vnc -display :5 -rfbport 5905 -bg
-vncviewer -FullScreen -PreferredEncoding raw -passwd $HOME/.vnc/passwd localhos
-t:5
-
-   This way a bare X server is run with no window manager or desktop; it
-   simply runs only the VNC Viewer on the real X server. The Viewer then
-   draws the virtual X session on to the real one. On your system it
-   might not be $HOME/.xinitrc, but rather .xsession, .Xclients, or
-   something else. You will need to figure out what it is for your system
-   and configuration.
-
-
-   XDM/GDM/KDM One-Shot X sessions: For the general replacement of Xvnc
-   by Xvfb+x11vnc, one user describes a similar setup he created where
-   the X sessions are one-shot's (destroyed after the vncviewer
-   disconnects) and it uses the XDM/GDM/KDM login greeter here.
-
-
-   Q-69: How can I use x11vnc on "headless" machines? Why might I want
-   to?
-
-   An interesting application of x11vnc is to let it export displays of
-   "headless" machines. For example, you may have some lab or server
-   machines with no keyboard, mouse, or monitor, but each one still has a
-   video card. One can use x11vnc to provide a simple "desktop service"
-   from these server machines.
-
-   An X server can be started on the headless machine (sometimes this
-   requires configuring the X server to not fail if it cannot detect a
-   keyboard or mouse, see the next paragraph.) Then you can export that X
-   display via x11vnc (e.g. see this FAQ) and access it from anywhere on
-   the network via a VNC viewer.
-
-   Some tips on getting X servers to start on machines without keyboard
-   or mouse: For XFree86/Xorg the Option "AllowMouseOpenFail" "true"
-   "ServerFlags" config file option is useful. On Solaris Xsun the
-   +nkeyboard and +nmouse options are useful (put them in the server
-   command line args in /etc/dt/config/Xservers.) There are patches
-   available for Xsun at lease back to Solaris 8 that support this. See
-   Xserver(1) for more info.
-
-   Although this usage may sound strange it can be quite useful for a GUI
-   (or other) testing or QA setups: the engineers do not need to walk to
-   lab machines running different hardware, OS's, versions, etc (or have
-   many different machines in their office.) They just connect to the
-   various test machines over the network via VNC. The advantage to
-   testing this way instead of using Xvnc or even Xvfb is that the test
-   is done using the real X server, fonts, video hardware, etc. that will
-   be used in the field.
-
-   One can imagine a single server machine crammed with as many video
-   cards as it can hold to provide multiple simultaneous access or
-   testing on different kinds of video hardware.
-
-   See also the FINDCREATEDISPLAY discussion of the "-display
-   WAIT:cmd=FINDDISPLAY" option where virtual Xvfb or Xdummy, or real X
-   servers are started automatically for new users connecting. The -find,
-   -create, -svc, and -xdmsvc aliases can also come in handy here.

-   Q-70: I have lots of memory, but why does x11vnc fail with    shmget:
-   No space left on device    or    Minor opcode of failed request: 1
-   (X_ShmAttach)?
-
-   It is not a matter of free memory, but rather free shared memory (shm)
-   slots, also known as shm segments. This often occurs on a public
-   Solaris machine using the default of only 100 slots. You (or the owner
-   or root) can clean them out with ipcrm(1). x11vnc tries hard to
-   release its slots, but it, and other programs, are not always able to
-   (e.g. if kill -9'd.)
-
-   Sometimes x11vnc will notice the problem with shm segments and tries
-   to get by with fewer, only giving a warning like this:
-  19/03/2004 10:10:58 shmat(tile_row) failed.
-  shmat: Too many open files
-  19/03/2004 10:10:58 error creating tile-row shm for len=4
-  19/03/2004 10:10:58 reverting to single_copytile mode
-
-   Here is a shell script shm_clear to list and prompt for removal of
-   your unattached shm segments (attached ones are skipped.) I use it
-   while debugging x11vnc (I use "shm_clear -y" to assume "yes" for each
-   prompt.) If x11vnc is regularly not cleaning up its shm segments,
-   please contact me so we can work to improve the situation.
-
-   Longer term, on Solaris you can put something like this in
-   /etc/system:
-  set shmsys:shminfo_shmmax = 0x2000000
-  set shmsys:shminfo_shmmni = 0x1000
-
-   to sweep the problem under the rug (4096 slots.) On Linux, examine
-   /proc/sys/kernel/shmmni; you can modify the value by writing to that
-   file.
-
-   Things are even more tight on Solaris 8 and earlier, there is a
-   default maximum number of shm segments per process of 6. The error is
-   the X server (not x11vnc) being unable to attach to the segments, and
-   looks something like this:
-  30/04/2004 14:04:26 Got connection from client 192.168.1.23
-  30/04/2004 14:04:26   other clients:
-  X Error of failed request:  BadAccess (attempt to access private resource den
-ied)
-     Major opcode of failed request:  131 (MIT-SHM)
-     Minor opcode of failed request:  1 (X_ShmAttach)
-     Serial number of failed request:  14
-     Current serial number in output stream:  17
-
-   This tight limit on Solaris 8 can be increased via:
-  set shmsys:shminfo_shmseg = 100
-
-   in /etc/system. See the next paragraph for more workarounds.
-
-   To minimize the number of shm segments used by x11vnc try using the
-   -onetile option (corresponds to only 3 shm segments used, and adding
-   -fs 1.0 knocks it down to 2.) If you are having much trouble with shm
-   segments, consider disabling shm completely via the -noshm option.
-   Performance will be somewhat degraded but when done over local machine
-   sockets it should be acceptable (see an earlier question discussing
-   -noshm.)
-
-
-   Q-71: How can I make x11vnc use less system resources?
-
-   The -nap (now on by default; use -nonap to disable) and "-wait n"
-   (where n is the sleep between polls in milliseconds, the default is 30
-   or so) option are good places to start. In addition, something like
-   "-sb 15" will cause x11vnc to go into a deep-sleep mode after 15
-   seconds of no activity (instead of the default 60.)
-
-   Reducing the X server bits per pixel depth (e.g. to 16bpp or even
-   8bpp) will further decrease memory I/O and network I/O. The ShadowFB X
-   server setting will make x11vnc's screen polling less severe. Using
-   the -onetile option will use less memory and use fewer shared memory
-   slots (add -fs 1.0 for one less slot.)
-
-
-   Q-72: How can I make x11vnc use MORE system resources?
-
-   You can try -threads (note this mode can be unstable and/or crash; and
-   as of May/2008 is strongly discouraged, see the option description) or
-   dial down the wait time (e.g. -wait 1) and possibly dial down -defer
-   as well. Note that if you try to increase the "frame rate" too much
-   you can bog down the server end with the extra work it needs to do
-   compressing the framebuffer data, etc.
-
-   That said, it is possible to "stream" video via x11vnc if the video
-   window is small enough. E.g. a 256x192 xawtv TV capture window (using
-   the x11vnc -id option) can be streamed over a LAN or wireless at a
-   reasonable frame rate. If the graphics card's framebuffer read rate is
-   faster than normal then the video window size and frame rate can be
-   much higher. The use of TurboVNC and/or TurboJPEG can make the frame
-   rate somewhat higher still (but most of this hinges on the graphics
-   card's read rate.)
-
-
-   Q-73: I use x11vnc over a slow link with high latency (e.g. dialup
-   modem or broadband), is there anything I can do to speed things up?
-
-   Some things you might want to experiment with (many of which will help
-   performance on faster links as well):
-
-     X server/session parameters:
-     * Configure the X server bits per pixel to be 16bpp or even 8bpp.
-       (reduces amount of data needed to be polled, compressed, and sent)
-     * Use a smaller desktop size (e.g. 1024x768 instead of 1280x1024)
-     * Make sure the desktop background is a solid color (the background
-       is resent every time it is re-exposed.) Consider using the -solid
-       [color] option to try to do this automatically.
-     * Configure your window manager or desktop "theme" to not use fancy
-       images, shading, and gradients for the window decorations, etc.
-       Disable window animations, etc. Maybe your desktop has a "low
-       bandwidth" theme you can easily switch into and out of. Also in
-       Firefox disable eye-candy, e.g.: Edit -> Preferences -> Advanced
-       -> Use Smooth Scrolling (deselect it.)
-     * Avoid small scrolls of large windows using the Arrow keys or
-       scrollbar. Try to use PageUp/PageDown instead. (not so much of a
-       problem in x11vnc 0.7.2 if -scrollcopyrect is active and detecting
-       scrolls for the application.)
-     * If the -wireframe option is not available (earlier than x11vnc
-       0.7.2 or you have disabled it via -nowireframe) then Disable
-       Opaque Moves and Resizes in the window manager/desktop.
-     * However if -wireframe is active (on by default in x11vnc 0.7.2)
-       then you should Enable Opaque Moves and Resizes in the window
-       manager! This seems counter-intuitive, but because x11vnc detects
-       the move/resize events early there is a huge speedup over a slow
-       link when Opaque Moves and Resizes are enabled. (e.g. CopyRect
-       encoding will be used.)
-     * Turn off Anti-aliased fonts on your system, web browser, terminal
-       windows, etc. AA fonts do not compress as well as traditional
-       fonts (sometimes 10X less.)
-     * On Firefox/Mozilla (and anything else) turn off "Smooth Scroll"
-       animations. In Firefox put in the URL "about:config" and set
-       general.smoothScroll to false.
-     * On Xorg/XFree86 turn on the Shadow Framebuffer to speed up
-       reading. (Option "ShadowFB" "true" in the Device section of
-       /etc/X11/XF86Config) This disables 2D acceleration on the physical
-       display and so may not be worth it (if you play games, etc), but
-       could be of use in some situations. Note: If the network link is
-       very slow, this speedup may not be noticed.
-
-     VNC viewer parameters:
-     * Use a TightVNC enabled viewer! (Actually, RealVNC 4.x viewer with
-       ZRLE encoding is not too bad either; some claim it is faster.)
-     * Make sure the tight (or zrle) encoding is being used (look at
-       vncviewer and x11vnc outputs)
-     * Request 8 bits per pixel using -bgr233 (up to 4X speedup over
-       depth 24 TrueColor (32bpp), but colors will be off)
-     * RealVNC 4.x viewer has some extremely low color modes (only 64 and
-       even 8 colors.) SSVNC does too. The colors are poor, but it is
-       usually noticeably faster than bgr233 (256 colors.)
-     * Try increasing the TightVNC -compresslevel (compresses more on
-       server side before sending, but uses more CPU)
-     * Try reducing the TightVNC -quality (increases JPEG compression,
-       but is lossy with painting artifacts)
-     * Try other VNC encodings via -encodings (tight may be the fastest,
-       but you should compare it to zrle and maybe some of the others)
-     * On the machine where vncviewer is run, make sure Backing Store is
-       enabled (Xorg/XFree86 disables it by default causing re-exposures
-       of vncviewer to be very slow) Option "backingstore" in config
-       file.
-
-     x11vnc parameters:
-     * Make sure the -wireframe option is active (it should be on by
-       default) and you have Opaque Moves/Resizes Enabled in the window
-       manager.
-     * Make sure the -scrollcopyrect option is active (it should be on by
-       default.) This detects scrolls in many (but not all) applications
-       an applies the CopyRect encoding for a big speedup.
-     * Enforce a solid background when VNC viewers are connected via
-       -solid
-     * Try x11vnc's client-side caching client-side caching scheme:
-       -ncache
-     * Specify -speeds modem to force the wireframe and scrollcopyrect
-       heuristic parameters (and any future ones) to those of a dialup
-       modem connection (or supply the rd,bw,lat numerical values that
-       characterize your link.)
-     * If wireframe and scrollcopyrect aren't working, try using the more
-       drastic -nodragging (no screen updates when dragging mouse, but
-       sometimes you miss visual feedback)
-     * Set -fs 1.0 (disables fullscreen updates)
-     * Try increasing -wait or -defer (reduces the maximum "frame rate",
-       but won't help much for large screen changes)
-     * Try the -progressive pixelheight mode with the block pixelheight
-       100 or so (delays sending vertical blocks since they may change
-       while viewer is receiving earlier ones)
-     * If you just want to watch one (simple) window use -id or -appshare
-       (cuts down extraneous polling and updates, but can be buggy or
-       insufficient)
-     * Set -nosel (disables all clipboard selection exchange)
-     * Use -nocursor and -nocursorpos (repainting the remote cursor
-       position and shape takes resources and round trips)
-     * On very slow links (e.g. <= 28.8) you may need to increase the
-       -readtimeout n setting if it sometimes takes more than 20sec to
-       paint the full screen, etc.
-     * Do not use -fixscreen to automatically refresh the whole screen,
-       tap three Alt_L's then the screen has painting errors (rare
-       problem.)

-
-   Q-74: Does x11vnc support the X DAMAGE Xserver extension to find
-   modified regions of the screen quickly and efficiently?
-
-   Yes, as of Mar/2005 x11vnc will use the X DAMAGE extension by default
-   if it is available on the display. This requires libXdamage to be
-   available in the build environment as well (recent Linux distros and
-   Solaris 10 have it.)
-
-   The DAMAGE extension enables the X server to report changed regions of
-   the screen back to x11vnc. So x11vnc doesn't have to guess where the
-   changes are (by polling every pixel of the entire screen every 2-4
-   seconds.) The use of X DAMAGE dramatically reduces the load when the
-   screen is not changing very much (i.e. most of the time.) It also
-   noticeably improves updates, especially for very small changed areas
-   (e.g. clock ticking, cursor flashing, typing, etc.)
-
-   Note that the DAMAGE extension does not speed up the actual reading of
-   pixels from the video card framebuffer memory, by, say, mirroring them
-   in main memory. So reading the fb is still painfully slow (e.g.
-   5MB/sec), and so even using X DAMAGE when large changes occur on the
-   screen the bulk of the time is still spent retrieving them. Not ideal,
-   but use of the ShadowFB XFree86/Xorg option speeds up the reading
-   considerably (at the cost of h/w acceleration.)
-
-   Unfortunately the current Xorg DAMAGE extension implementation can at
-   times be overly conservative and report very large rectangles as
-   "damaged" even though only a small portion of the pixels have actually
-   been modified. This behavior is often the fault of the window manager
-   (e.g. it redraws the entire, unseen, frame window underneath the
-   application window when it gains focus), or the application itself
-   (e.g. does large, unnecessary repaints.)
-
-   To work around this deficiency, x11vnc currently only trusts small
-   DAMAGE rectangles to contain real damage. The larger rectangles are
-   only used as hints to focus the traditional scanline polling (i.e. if
-   a scanline doesn't intersect a recent DAMAGE rectangle, the scan is
-   skipped.) You can use the "-xd_area A" option to adjust the size of
-   the trusted DAMAGE rectangles. The default is 20000 pixels (e.g. a
-   140x140 square, etc.) Use "-xd_area 0" to disable the cutoff and trust
-   all DAMAGE rectangles.
-
-   The option "-xd_mem f" may also be of use in tuning the algorithm. To
-   disable using DAMAGE entirely use "-noxdamage".
-
-
-   Q-75: My OpenGL application shows no screen updates unless I supply
-   the -noxdamage option to x11vnc.
-   One user reports in his environment (MythTV using the NVIDIA OpenGL
-   drivers) he gets no updates after the initial screen is drawn unless
-   he uses the "-noxdamage" option.
-
-   This seems to be a bug in the X DAMAGE implementation of that driver.
-   You may have to use -noxdamage as well. A way to autodetect this will
-   be tried, probably the best it will do is automatically stop using X
-   DAMAGE.
-
-   A developer for MiniMyth reports that the 'alphapulse' tag of the
-   theme G.A.N.T. can also cause problems, and should be avoided when
-   using VNC.
-
-   Update: see this FAQ too.
-
-
-   Q-76: When I drag windows around with the mouse or scroll up and down
-   things really bog down (unless I do the drag in a single, quick
-   motion.) Is there anything to do to improve things?
-
-   This problem is primarily due to slow hardware read rates from video
-   cards: as you scroll or move a large window around the screen changes
-   are much too rapid for x11vnc to keep up them (it can usually only
-   read the video card at about 5-10 MB/sec, so it can take a good
-   fraction of a second to read the changes induce from moving a large
-   window, if this to be done a number of times in succession the window
-   or scroll appears to "lurch" forward.) See the description in the
-   -pointer_mode option for more info. The next bottleneck is compressing
-   all of these changes and sending them out to connected viewers,
-   however the VNC protocol is pretty much self-adapting with respect to
-   that (updates are only packaged and sent when viewers ask for them.)
-
-   As of Jan/2004 there are some improvements to libvncserver. The
-   default should now be much better than before and dragging small
-   windows around should no longer be a huge pain. If for some reason
-   these changes make matters worse, you can go back to the old way via
-   the "-pointer_mode 1" option.
-
-   Also added was the -nodragging option that disables all screen updates
-   while dragging with the mouse (i.e. mouse motion with a button held
-   down.) This gives the snappiest response, but might be undesired in
-   some circumstances when you want to see the visual feedback while
-   dragging (e.g. menu traversal or text selection.)
-
-   As of Dec/2004 the -pointer_mode n option was introduced. n=1 is the
-   original mode, n=2 an improvement, etc.. See the -pointer_mode n help
-   for more info.
-
-   Also, in some circumstances the -threads option can improve response
-   considerably. Be forewarned that if more than one vncviewer is
-   connected at the same time then libvncserver may not be thread safe
-   (try to get the viewers to use different VNC encodings, e.g. tight and
-   ZRLE.) This option can be unstable and so as of Feb/2008 it is
-   disabled by default. Set env. X11VNC_THREADED=1 to re-enable.
-
-   As of Apr/2005 two new options (see the wireframe FAQ and
-   scrollcopyrect FAQ below) provide schemes to sweep this problem under
-   the rug for window moves or resizes and for some (but not all) window
-   scrolls. These are the preferred way of avoiding the "lurching"
-   problem, contact me if they are not working. Note on SuSE and some
-   other distros the RECORD X extension used by scrollcopyrect is not
-   enabled by default, turn it on in xorg.conf:
-Section "Module"
-        ...
-        Load  "record"
-        ...
-EndSection
-
-
-   Q-77: Why not do something like wireframe animations to avoid the
-   windows "lurching" when being moved or resized?
-
-   Nice idea for a hack! As of Apr/2005 x11vnc by default will apply
-   heuristics to try to guess if a window is being (opaquely) moved or
-   resized. If such a change is detected framebuffer polling and updates
-   will be suspended and only an animated "wireframe" (a rectangle
-   outline drawn where the moved/resized window would be) is shown. When
-   the window move/resize stops, it returns to normal processing: you
-   should only see the window appear in the new position. This spares you
-   from interacting with a "lurching" window between all of the
-   intermediate steps. BTW the lurching is due to slow video card read
-   rates (see here too.) A displacement, even a small one, of a large
-   window requires a non-negligible amount of time, a good fraction of a
-   second, to read in from the hardware framebuffer.
-
-   Note that Opaque Moves/Resizes must be Enabled by your window manager
-   for -wireframe to do any good.
-
-   The mode is currently on by default because most people are afflicted
-   with the problem. It can be disabled with the -nowireframe option (aka
-   -nowf.) Why might one want to turn off the wireframing? Since x11vnc
-   is merely guessing when windows are being moved/resized, it may guess
-   poorly for your window-manager or desktop, or even for the way you
-   move the pointer. If your window-manager or desktop already does its
-   own wireframing then this mode is a waste of time and could do the
-   wrong thing occasionally. There may be other reasons the new mode
-   feels unnatural. If you have very expensive video hardware (SGI, well
-   now even proprietary Xorg drivers are fast at reading) or are using an
-   in-RAM video framebuffer (SunRay, ShadowFB, Xvfb), the read rate from
-   that framebuffer may be very fast (100's of MB/sec) and so you don't
-   really see much lurching (at least over a fast LAN): opaque moves look
-   smooth in x11vnc. Note: ShadowFB is often turned on when you are using
-   the vesafb or fbdev XFree86 video driver instead of a native one so
-   you might be using it already and not know.
-
-   The heuristics used to guess window motion or resizing are simple, but
-   are not fool proof: x11vnc is sometimes tricked and so you'll
-   occasionally see the lurching opaque move and rarely something even
-   worse.
-
-   First it assumes that the move/resize will occur with a mouse button
-   pressed, held down and dragged (of course this is only mostly true.)
-   Next it will only consider a window for wireframing if the mouse
-   pointer is initially "close enough" to the edges of the window frame,
-   e.g. you have grabbed the title bar or a resizer edge (this
-   requirement can be disabled and it also not applied if a modifier key,
-   e.g. Alt, is pressed.) If these are true, it will wait an amount of
-   time to see if the window starts moving or resizing. If it does, it
-   starts drawing the wireframe "outline" of where the window would be.
-   When the mouse button is released, or a timeout occurs, it goes back
-   to the standard mode to allow the actual framebuffer changes to
-   propagate to the viewers.
-
-   These parameters can be tweaked:
-     * Color/Shade of the wireframe.
-     * Linewidth of the outline frame.
-     * Cutoff size of windows to not apply wireframing to.
-     * Cutoffs for closeness to Top, Bottom, Left, and Right edges of
-       window.
-     * Modifier keys to enable interior window grabbing.
-     * Maximum time to wait for dragging pointer events.
-     * Maximum time to wait for the window to start moving/resizing.
-     * Maximum time to show a wireframe animation.
-     * Minimum time between sending wireframe outlines.
-
-   See the "-wireframe tweaks" option for more details. On a slow link,
-   e.g. dialup modem, the parameters may be automatically adjusted for
-   better response.
-
-
-   CopyRect encoding:  In addition to the above there is the
-   "-wirecopyrect mode" option. It is also on by default. This instructs
-   x11vnc to not only show the wireframe animation, but to also instruct
-   all connected VNC viewers to locally translate the window image data
-   from the original position to the new position on the screen when the
-   animation is done. This speedup is the VNC CopyRect encoding: the
-   framebuffer update doesn't need to send the actual new image data.
-   This is nice in general, and very convenient over a slow link, but
-   since it is based on heuristics you may need to disable it with the
-   -nowirecopyrect option (aka -nowcr) if it works incorrectly or
-   unnaturally for you.
-
-   The -wirecopyrect modes are: "never" (same as -nowirecopyrect); "top",
-   only apply the CopyRect if the window is appears to be on the top of
-   the window stack and is not obstructed by other windows; and "always"
-   to always try to apply the CopyRect (obstructed regions are usually
-   clipped off and not translated.)
-
-   Note that some desktops (KDE and xfce) appear to mess with the window
-   stacking in ways that are not yet clear. In these cases x11vnc works
-   around the problem by applying the CopyRect even if obscuring windows'
-   data is translated! Use -nowirecopyrect if this yields undesirable
-   effects for your desktop.
-
-   Also, the CopyRect encoding may give incorrect results under -scale
-   (depending on the scale factor the CopyRect operation is often only
-   approximate: the correctly scaled framebuffer will be slightly
-   different from the translated one.) x11vnc will try to push a
-   "cleanup" update after the CopyRect if -scale is in effect. Use
-   -nowirecopyrect if this or other painting errors are unacceptable.
-
-
-   Q-78: Can x11vnc try to apply heuristics to detect when a window is
-   scrolling its contents and use the CopyRect encoding for a speedup?
-
-   Another nice idea for a hack! As of May/2005 x11vnc will by default
-   apply heuristics to try to detect if the window that has the input
-   focus is scrolling its contents (but only when x11vnc is feeding user
-   input, keystroke or pointer, to the X server.) So, when detected,
-   scrolls induced by dragging on a scrollbar or by typing (e.g. Up or
-   Down arrows, hitting Return in a terminal window, etc), will show up
-   much more quickly than via the standard x11vnc screen polling update
-   mechanism.
-
-   There will be a speedup for both slow and fast links to viewers. For
-   slow links the speedup is mostly due to the CopyRect encoding not
-   requiring the image data to be transmitted over the network. For fast
-   links the speedup is primarily due to x11vnc not having to read the
-   scrolled framebuffer data from the X server (recall that reading from
-   the hardware framebuffer is slow.)
-
-   To do this x11vnc uses the RECORD X extension to snoop the X11
-   protocol between the X client with the focus window and the X server.
-   This extension is usually present on most X servers (but SuSE disables
-   it for some reason.) On XFree86/Xorg it can be enabled via Load
-   "record" in the Module section of the config file if it isn't already:
-Section "Module"
-        ...
-        Load  "record"
-        ...
-EndSection
-
-   Currently the RECORD extension is used as little as possible so as to
-   not slow down regular use. Only simple heuristics are applied to
-   detect XCopyArea and XConfigureWindow calls from the application.
-   These catch a lot of scrolls, e.g. in mozilla/firefox and in terminal
-   windows like gnome-terminal and xterm. Unfortunately the toolkits KDE
-   applications use make scroll detection less effective (only rarely are
-   they detected: i.e. Konqueror and Konsole don't work.) An interesting
-   project, that may be the direction x11vnc takes, is to record all of
-   the X11 protocol from all clients and try to "tee" the stream into a
-   modified Xvfb watching for CopyRect and other VNC speedups. A
-   potential issue is the RECORD stream is delayed from actual view on
-   the X server display: if one falls too far behind it could become a
-   mess...
-
-   The initial implementation of -scrollcopyrect option is useful in that
-   it detects many scrolls and thus gives a much nicer working
-   environment (especially when combined with the -wireframe
-   -wirecopyrect options, which are also on by default; and if you are
-   willing to enable the ShadowFB things are very fast.) The fact that
-   there aren't long delays or lurches during scrolling is the primary
-   improvement.
-
-   But there are some drawbacks:
-     * Not all scrolls are detected. Some apps scroll windows in ways
-       that cannot currently be detected, and other times x11vnc "misses"
-       the scroll due to timeouts, etc. Sometimes it is more distracting
-       that a speedup occasionally doesn't work as opposed to being
-       consistently slow!
-     * For rapid scrolling (i.e. sequence of many scrolls over a short
-       period) there can be painting errors (tearing, bunching up, etc.)
-       during the scroll. These will repair themselves after the scroll
-       is over, but when they are severe it can be distracting. Try to
-       think of the approximate window contents as a quicker and more
-       useful "animation" compared to the slower polling scheme...
-     * Scrolling inside shells in terminal windows (gnome-terminal,
-       xterm), can lead to odd painting errors. This is because x11vnc
-       did not have time to detect a screen change just before the scroll
-       (most common is the terminal undraws the block cursor before
-       scrolling the text up: in the viewer you temporarily see multiple
-       block cursors.) Another issue is with things like more(1): scroll
-       detection for 5-6 lines happens nicely, but then it can't keep up
-       and so there is a long pause for the standard polling method to
-       deliver the remaining updates.
-     * More rarely sometimes painting errors are not repaired after the
-       scroll is over. This may be a bug in x11vnc or libvncserver, or it
-       may be an inescapable fact of the CopyRect encoding and the delay
-       between RECORD callbacks and what is actually on the X display.
-       One can tap the Alt_L key (Left "Alt" key) 3 times in a row to
-       signal x11vnc to refresh the screen to all viewers. Your
-       VNC-viewer may have its own screen refresh hot-key or button. See
-       also: -fixscreen
-     * Some applications, notably OpenOffice, do XCopyArea scrolls in
-       weird ways that assume ancestor window clipping is taking place.
-       See the -scr_skip option for ways to tweak this on a
-       per-application basis.
-     * Selecting text while dragging the mouse may be slower, especially
-       if the Button-down event happens near the window's edge. This is
-       because the scrollcopyrect scheme is watching for scrolls via
-       RECORD and has to wait for a timeout to occur before it does the
-       update.
-     * For reasons not yet understood the RECORD extension can stop
-       responding (and hence scrolls are missed.) As a workaround x11vnc
-       attempts to reset the RECORD connection every 60 seconds or so.
-       Another workaround is to type 4 Super_L (Left Super/Windows-Flag
-       key) in a row to reset RECORD. Work is in progress to try to fix
-       this bug.
-     * Sometimes you need to "retrain" x11vnc for a certain window
-       because it fails to detect scrolls in it. Sometimes clicking
-       inside the application window or selecting some text in it to
-       force the focus helps.
-     * When using the -scale option there will be a quick CopyRect
-       scroll, but it needs to be followed by a slower "cleanup" update.
-       This is because for a fixed finite screen resolution (e.g. 75 dpi)
-       scaling and copyrect-ing are not exactly independent. Scaling
-       involves a blending of nearby pixels and if you translate a pixel
-       the neighbor pixel weighting may be different. So you have to wait
-       a bit for the cleanup update to finish. On slow links x11vnc may
-       automatically decide to not detect scrolls when -scale is in
-       effect. In general it will also try to defer the cleanup update if
-       possible.
-
-   If you find the -scrollcopyrect behavior too approximate or
-   distracting you can go back to the standard polling-only update method
-   with the -noscrollcopyrect (or -noscr for short.) If you find some
-   extremely bad and repeatable behavior for -scrollcopyrect please
-   report a bug.
-
-   Alternatively, as with -wireframe, there are many tuning parameters to
-   try to improve the situation. You can also access these parameters
-   inside the gui under "Tuning". These parameters can be tweaked:
-     * The minimum pixel area of a rectangle to be watched for scrolls.
-     * A list if application names to skip scroll detection.
-     * Which keystrokes should trigger scroll detection.
-     * Which applications should have a "terminal" tweak applied to them.
-     * When repeating keys (e.g. Up arrow) should be discarded to
-       preserve a scroll.
-     * Cutoffs for closeness to Top, Bottom, Left, and Right edges of
-       window for mouse induced scrolls.
-     * Set timeout parameters for keystroke induced scrolls.
-     * Set timeout parameters for mouse pointer induced scrolls.
-     * Have the full screen be periodically refreshed to fix painting
-       errors.
-
-
-   Q-79: Can x11vnc do client-side caching of pixel data? I.e. so when
-   that pixel data is needed again it does not have to be retransmitted
-   over the network.
-
-   As of Dec/2006 in the 0.9 development tarball there is an experimental
-   client-side caching implementation enabled by the "-ncache n" option.
-   In fact, during the test period it was on by default with n set to 10.
-   To disable it use "-noncache".
-
-   It is a simple scheme where a (very large) lower portion of the
-   framebuffer (i.e. starting just below the user's actual desktop
-   display) is used for storing pixel data. CopyRect; a fast, essentially
-   local viewer-side VNC encoding; is used to swap the pixel data in and
-   out of the actual display area. It gives an excellent speedup for
-   iconifying/deiconifying and moving windows and re-posting of menus
-   (often it doesn't feel like VNC at all: there is no delay waiting for
-   the pixel data to fill in.)
-
-   This scheme is nice because it does all of this within the existing
-   VNC protocol, and so it works with all VNC viewers.
-
-   A challenge to doing more sophisticated (e.g. compressed and/or
-   shared) client-side caching is that one needs to extend the VNC
-   protocol, modify a viewer and then also convince users to adopt your
-   modified VNC Viewer (or get the new features to be folded into the
-   main VNC viewers, patches accepted, etc... likely takes many years
-   before they might be deployed in the field.) So it is convenient that
-   the "-ncache n" works with any unaltered VNC viewer.
-
-   A drawback of the "-ncache n" method is that in the VNC Viewer you can
-   scroll down and actually see the cached pixel data. So it looks like
-   there is a bug: you can scroll down in your viewer and see a strange
-   "history" of windows on your desktop. This is working as intended. One
-   will need to try to adjust the size of his VNC Viewer window so the
-   cache area cannot be seen. SSVNC (see below) can do this
-   automatically.
-
-   At some point LibVNCServer may implement a "rfbFBCrop" pseudoencoding
-   that viewers can use to learn which portion of the framebuffer to
-   actually show to the users (with the hidden part used for caching, or
-   perhaps something else, maybe double buffering or other offscreen
-   rendering...)
-
-   The Enhanced TightVNC Viewer (SSVNC) Unix viewer has a nice -ycrop
-   option to help hide the pixel cache area from view. It will turn on
-   automatically if the framebuffer appears to be very tall (height more
-   than twice the width), or you can supply the actual value for the
-   height. If the screen is resized by scaling, etc, the ycrop value is
-   scaled as well. In fullscreen mode you cannot scroll past the end of
-   the actual screen, and in non-fullscreen mode the window manager frame
-   is adjusted to fit the actual display (so you don't see the pixel
-   cache region) and the scrollbars are very thin to avoid distraction
-   and trouble fitting inside your display. Use the "-sbwidth n" viewer
-   option to make the scrollbars thicker if you like.
-
-   Another drawback of the scheme is that it is VERY memory intensive,
-   the n in "-ncache n" is the factor of increase over the base
-   framebuffer size to use for caching. It is an even integer and should
-   be fairly large, 6-12, to achieve good response. This usually requires
-   about 50-100MB of additional RAM on both the client and server sides.
-   For example with n=6 a 1280x1024 display will use a framebuffer that
-   is 1280x7168: everything below row 1024 is the pixel buffer cache. If
-   you are running on low memory machines or memory is tight because of
-   other running applications you should not use -ncache.
-
-   The reason for so much memory is because the pixel data is not
-   compressed and so the whole window to be saved must be stored
-   "offscreen". E.g. for a large web browser window this can be nearly 1
-   million pixels, and that is only for a single window! One typically
-   wants to cycle between 5-10 large active windows. Also because both
-   backing-store (the window's actual contents) and save-unders (the
-   pixels covered up by the window) are cached offscreen that introduces
-   an additional factor of 2 in memory use.
-
-   However, even in the smallest usage mode with n equal 2 and
-   -ncache_no_rootpixmap set (this requires only 2X additional
-   framebuffer memory) there is still a noticable improvement for many
-   activities, although it is not as dramatic as with, say n equal 12 and
-   rootpixmap (desktop background) caching enabled.
-
-   The large memory consumption of the current implementation can be
-   thought of as a tradeoff to providing caching and being compatible
-   with all VNC viewers and also ease of implementing. Hopefully it can
-   be tuned to use less, or the VNC community will extend the protocol to
-   allow caching and replaying of compressed blobs of data.
-
-   Another option to experiment with is "-ncache_cr". By specifying it,
-   x11vnc will try to do smooth opaque window moves instead of its
-   wireframe. This can give a very nice effect (note: on Unix the realvnc
-   viewer seems to be smoother than the tightvnc viewer), but can lead to
-   some painting problems, and can be jerky in some circumstances.
-
-   Surprisingly, for very slow connections, e.g. modem, the -ncache_cr
-   option can actually improve window drags. This is probably because no
-   pixel data (only CopyRect instructions) are sent when dragging a
-   window. Normally, the wireframe must be sent and this involves
-   compressing and sending the lines that give rise to the moving box
-   effect (note that real framebuffer data is sent to "erase" the white
-   lines of the box.)
-
-   If you experience painting errors you can can tap the Alt_L key (Left
-   "Alt" key) 3 times in a row to signal x11vnc to refresh the screen to
-   all viewers. You may also need to iconify and then deiconify any
-   damaged windows to correct their cache data as well. Note that if you
-   change color viewer depth (e.g. 8bpp to full color) dynamically that
-   will usually lead to the entire extended framebuffer being resent
-   which can take a long time over very slow links: it may be better to
-   reconnect and reset the format right after doing so. x11vnc will try
-   to detect the format change and clear (make completely black) the
-   cache region.
-
-   Gotcha for older Unix VNC Viewers: The older Unix VNC viewers (e.g.
-   current TightVNC Unix Viewer) require X server backingstore to keep
-   off-viewer screen data local. If the viewer-side X server has
-   backingstore disabled (sadly, currently the default on Linux, etc),
-   then to get the offscreen pixels the viewer has to ask for a refresh
-   over the network, thereby defeating the caching. Use something like
-   this in your viewer-side /etc/X11/xorg.conf file (or otherwise get
-   your viewer-side system to do it)
-Section "Device"
-        ...
-        Option  "backingstore"
-        ...
-EndSection
-
-   No problems like this have been observed with Windows VNC Viewers:
-   they all seem to keep their entire framebuffer in local memory.
-
-   Gotcha for KDE krdc VNC Viewer: One user found that KDE's krdc viewer
-   has some sort of hardwired limit on the maximum size of the
-   framebuffer (64MB?). It fails quickly saying "The connection to the
-   host has been interrupted." The workaround for his 1280x1024
-   x11vnc-side display was to run with "-ncache 10", i.e. a smaller value
-   to be under the krdc threshold.
-
-   Although this scheme is not as quick (nor as compressed) as
-   nx/nomachine, say, it does provide a good step in the direction of
-   improving VNC performance by client side caching.
-
-
-   Q-80: Does x11vnc support TurboVNC?
-
-   As of Feb/2009 (development tarball) there is an experimental kludge
-   to let you build x11vnc using TurboVNC's modified TightVNC encoding.
-   TurboVNC is part of the VirtualGL project. It does two main things to
-   speed up the TightVNC encoding:
-     * It eliminates bottlenecks, overheads, wait-times in the TightVNC
-       encoding implementation and instead only worries about sending
-       very well (and quickly) compressed JPEG data.
-     * A fast proprietary JPEG implemention is used (Intel IPP on x86)
-       instead of the usual libjpeg implementation. TurboJPEG is an
-       interface library, libturbojpeg, provided by the project that
-       achieves this.
-
-   TurboVNC works very well over LAN and evidently fast Broadband too.
-   When using it with x11vnc in such a situation you may want to dial
-   down the delays, e.g. "-wait 5" and "-defer 5" (or even a smaller
-   setting) to poll and pump things out more quickly.
-
-   See the instructions in "x11vnc/misc/turbovnc/README" for how to build
-   x11vnc with TurboVNC support. You will also need to download the
-   TurboJPEG software.
-
-   In brief, the steps look like this:
-  cd x11vnc-x.y.z/x11vnc/misc/turbovnc
-  ./apply_turbovnc
-  cd ../../..
-  env LDFLAGS='-L/DIR -Xlinker --rpath=/DIR' ./configure
-  make AM_LDFLAGS='-lturbojpeg'
-
-   where you replace "/DIR" with the directory containing libturbojpeg.so
-   you downloaded separately. If it works out well enough TurboVNC
-   support will be integrated into x11vnc and more of its tuning features
-   will be implemented. Support for TurboVNC in SSVNC viewer has been
-   added as an experiment as well. If you try either one, let us know how
-   it went.
-
-   There also may be some Linux.i686 and Darwin.i386 x11vnc binaries with
-   TurboVNC support in the misc. bins directory. For other platforms you
-   will need to compile yourself.
-
-   On relatively cheap and old hardware (Althon64 X2 5000+ / GeForce
-   6200) x11vnc and SSVNC, both TurboVNC enabled, were able to sustain
-   13.5 frames/sec (fps) and 15 Megapixels/sec using the VirtualGL
-   supplied OpenGL benchmark program glxspheres. VirtualGL on higher-end
-   hardware can sustain 20-30 fps with the glxspheres benchmark.
-
-   Potential Slowdown: As we describe elsewhere, unless you use x11vnc
-   with an X server using, say, NVidia proprietary drivers (or a virtual
-   X server like Xvfb or Xdummy, or in ShadowFB mode), then the read rate
-   from the graphics card can be rather slow (e.g. 10 MB/sec) and becomes
-   the bottleneck when using x11vnc over fast networks. Note that all of
-   Xorg's drivers currently (2009) have slow read rates (only proprietary
-   drivers appear to have optimized reads.)
-
-   So under these (more or less typical) conditions, the speed
-   improvement provided by TurboVNC may only be marginal. Look for this
-   output to see your read rate:
-  28/02/2009 11:11:07 Autoprobing TCP port
-  28/02/2009 11:11:07 Autoprobing selected port 5900
-  28/02/2009 11:11:08 fb read rate: 10 MB/sec
-  28/02/2009 11:11:08 screen setup finished.
-
-   A rate of 10 MB/sec means a 1280x1024x24 screen takes 0.5 seconds to
-   read in. TurboVNC compresses that to JPEG in a much shorter time. On
-   the other hand, an NVidia driver may have a read rate of 250 MB/sec
-   and so only takes 0.02 seconds to read the entire screen in.
-

-
-   [Mouse Cursor Shapes]
-
-   Q-81: Why isn't the mouse cursor shape (the little icon shape where
-   the mouse pointer is) correct as I move from window to window?
-
-   On X servers supporting XFIXES or Solaris/IRIX Overlay extensions it
-   is possible for x11vnc to do this correctly. See a few paragraphs down
-   for the answer.
-
-   Historically, the X11 mouse cursor shape (i.e. little picture: an
-   arrow, X, I-beam, resizer, etc) is one of the few WRITE-only objects
-   in X11. That is, an application can tell the X server what the cursor
-   shape should be when the pointer is in a given window, but a program
-   (like x11vnc) unfortunately cannot read this information. I believe
-   this is because the cursor shape is often downloaded to the graphics
-   hardware (video card), but I could be mistaken.
-
-   A simple kludge is provided by the "-cursor X" option that changes the
-   cursor when the mouse is on the root background (or any window has the
-   same cursor as the root background.) Note that desktops like GNOME or
-   KDE often cover up the root background, so this won't work for those
-   cases. Also see the "-cursor some" option for additional kludges.
-
-   Note that as of Aug/2004 on Solaris using the SUN_OVL overlay
-   extension and IRIX, x11vnc can show the correct mouse cursor when the
-   -overlay option is supplied. See this FAQ for more info.
-
-   Also as of Dec/2004 XFIXES X extension support has been added to allow
-   exact extraction of the mouse cursor shape. XFIXES fixes the problem
-   of the cursor-shape being write-only: x11vnc can now query the X
-   server for the current shape and send it back to the connected
-   viewers. XFIXES is available on recent Linux Xorg based distros and
-   Solaris 10.
-
-   The only XFIXES issue is the handling of alpha channel transparency in
-   cursors. If a cursor has any translucency then in general it must be
-   approximated to opaque RGB values for use in VNC. There are some
-   situations where the cursor transparency can also handled exactly:
-   when the VNC Viewer requires the cursor shape be drawn into the VNC
-   framebuffer or if you apply a patch to your VNC Viewer to extract
-   hidden alpha channel data under 32bpp. Details can be found here.
-
-
-   Q-82: When using XFIXES cursorshape mode, some of the cursors look
-   really bad with extra black borders around the cursor and other cruft.
-   How can I improve their appearance?
-
-   This happens for cursors with transparency ("alpha channel"); regular
-   X cursors (bitmaps) should be correct. Unfortunately x11vnc 0.7 was
-   released with a very poor algorithm for approximating the
-   transparency, which led to the ugly black borders.
-
-   The problem is as follows: XFIXES allows x11vnc to retrieve the
-   current X server cursor shape, including the alpha channel for
-   transparency. For traditional bitmap cursors the alpha value will be 0
-   for completely transparent pixels and 255 for completely opaque
-   pixels; whereas for modern, eye-candy cursors an alpha value between 0
-   and 255 means to blend in the background colors to that degree with
-   the cursor colors. The pixel color blending formula is something like
-   this: Red = Red_cursor * a + Red_background * (1 - a), (where here 0
-   =< a =< 1), with similar for Green and Blue. The VNC protocol does not
-   currently support an alpha channel in cursors: it only supports
-   regular X bitmap cursors and Rich Cursors that have RGB (Red, Green,
-   Blue) color data, but no "A" = alpha data. So in general x11vnc has to
-   approximate a cursor with transparency to create a Rich Cursor. This
-   is easier said than done: some cursor themes have cursors with
-   complicated drop shadows and other forms of translucency.
-
-   Anyway, for the x11vnc 0.7.1 release the algorithm for approximating
-   transparency is much improved and hopefully gives decent cursor shapes
-   for most cursor themes and you don't have to worry about it.
-
-   In case it still looks bad for your cursor theme, there are (of
-   course!) some tunable parameters. The "-alphacut n" option lets you
-   set the threshold "n" (between 0 and 255): cursor pixels with alpha
-   values below n will be considered completely transparent while values
-   equal to or above n will be completely opaque. The default is 240. The
-   "-alphafrac f" option tries to correct individual cursors that did not
-   fare well with the default -alphacut value: if a cursor has less than
-   fraction f (between 0.0 and 1.0) of its pixels selected by the default
-   -alphacut, the threshold is lowered until f of its pixels are
-   selected. The default fraction is 0.33.
-
-   Finally, there is an option -alpharemove that is useful for themes
-   where many cursors are light colored (e.g. "whiteglass".) XFIXES
-   returns the cursor data with the RGB values pre-multiplied by the
-   alpha value. If the white cursors look too grey, specify -alpharemove
-   to brighten them by having x11vnc divide out the alpha value.
-
-   One user played with these parameters and reported back:
- Of the cursor themes present on my system:
-
-   gentoo and gentoo-blue:   alphacut:192 - noalpharemove
-
-   gentoo-silver:            alphacut:127 and alpharemove
-
-   whiteglass and redglass (presumably also handhelds, which is based
-   heavily on redglass) look fine with the apparent default of alphacut:255.
-
-
-   Q-83: In XFIXES mode, are there any hacks to handle cursor
-   transparency ("alpha channel") exactly?
-
-   As of Jan/2005 libvncserver has been modified to allow an alpha
-   channel (i.e. RGBA data) for Rich Cursors. So x11vnc can now send the
-   alpha channel data to libvncserver. However, this data will only be
-   used for VNC clients that do not support the CursorShapeUpdates VNC
-   extension (or have disabled it.) It can be disabled for all clients
-   with the -nocursorshape x11vnc option. In this case the cursor is
-   drawn, correctly blended with the background, into the VNC framebuffer
-   before being sent out to the client. So the alpha blending is done on
-   the x11vnc side. Use the -noalphablend option to disable this behavior
-   (always approximate transparent cursors with opaque RGB values.)
-
-   The CursorShapeUpdates VNC extension complicates matters because the
-   cursor shape is sent to the VNC viewers supporting it, and the viewers
-   draw the cursor locally. This improves response over slow links. Alpha
-   channel data for these locally drawn cursors is not supported by the
-   VNC protocol.
-
-   However, in the libvncserver CVS there is a patch to the TightVNC
-   viewer to make this work for CursorShapeUpdates under some
-   circumstances. This hack is outside of the VNC protocol. It requires
-   the screens on both sides to be depth 24 at 32bpp (it uses the extra 8
-   bits to secretly hide the cursor alpha channel data.) Not only does it
-   require depth 24 at 32bpp, but it also currently requires the client
-   and server to be of the same endianness (otherwise the hidden alpha
-   data gets reset to zero by a libvncserver translation function; we can
-   fix this at some point if there is interest.) The patch is for the
-   TightVNC 1.3dev5 Unix vncviewer and it enables the TightVNC viewer to
-   do the cursor alpha blending locally. The patch code should give an
-   example on how to change the Windows TightVNC viewer to achieve the
-   same thing (send me the patch if you get that working.)
-
-   This patch is applied to the Enhanced TightVNC Viewer (SSVNC) package
-   we provide.
-
-   [Mouse Pointer]
-
-   Q-84: Why does the mouse arrow just stay in one corner in my
-   vncviewer, whereas my cursor (that does move) is just a dot?
-
-   This default takes advantage of a tightvnc extension
-   (CursorShapeUpdates) that allows specifying a cursor image shape for
-   the local VNC viewer. You may disable it with the -nocursor option to
-   x11vnc if your viewer does not have this extension.
-
-   Note: as of Aug/2004 this should be fixed: the default for
-   non-tightvnc viewers (or ones that do not support CursorShapeUpdates)
-   will be to draw the moving cursor into the x11vnc framebuffer. This
-   can also be disabled via -nocursor.
-
-
-   Q-85: Can I take advantage of the TightVNC extension to the VNC
-   protocol where Cursor Positions Updates are sent back to all connected
-   clients (i.e. passive viewers can see the mouse cursor being moved
-   around by another viewer)?
-
-   Use the -cursorpos option when starting x11vnc. A VNC viewer must
-   support the Cursor Positions Updates for the user to see the mouse
-   motions (the TightVNC viewers support this.) As of Aug/2004 -cursorpos
-   is the default. See also -nocursorpos and -nocursorshape.
-
-
-   Q-86: Is it possible to swap the mouse buttons (e.g. left-handed
-   operation), or arbitrarily remap them? How about mapping button clicks
-   to keystrokes, e.g. to partially emulate Mouse wheel scrolling?
-
-   You can remap the mouse buttons via something like: -buttonmap 13-31
-   (or perhaps 12-21.) Also, note that xmodmap(1) lets you directly
-   adjust the X server's button mappings, but in some circumstances it
-   might be more desirable to have x11vnc do it.
-
-   One user had an X server with only one mouse button(!) and was able to
-   map all of the VNC client mouse buttons to it via: -buttonmap 123-111.
-
-   Note that the -debug_pointer option prints out much info for every
-   mouse/pointer event and is handy in solving problems.
-
-   To map mouse button clicks to keystrokes you can use the alternate
-   format where the keystrokes are enclosed between colons like this
-   :<KeySym>: in place of the mouse button digit. For a sequence of
-   keysyms separate them with "+" signs. Look in the include file
-   <X11/keysymdef.h>, or use xev(1), or -debug_keyboard to find the
-   keysym names. Button clicks can also be included in the sequence via
-   the fake keysyms Button1, etc.
-
-   As an example, suppose the VNC viewer machine has a mouse wheel (these
-   generate button 4 and 5 events), but the machine that x11vnc is run on
-   only has the 3 regular buttons. In normal operation x11vnc will
-   discard the button 4 and 5 events. However, either of the following
-   button maps could possibly be of use emulating the mouse wheel events
-   in this case:
-  -buttonmap 12345-123:Prior::Next:
-  -buttonmap 12345-123:Up+Up+Up::Down+Down+Down:
-
-   Exactly what keystroke "scrolling" events they should be bound to
-   depends on one's taste. If this method is too approximate, one could
-   consider not using -buttonmap but rather configuring the X server to
-   think it has a mouse with 5 buttons even though the physical mouse
-   does not. (e.g. 'Option "ZAxisMapping" "4 5"'.)
-
-   Note that when a keysym-mapped mouse button is clicked down this
-   immediately generates the key-press and key-release events (for each
-   keysym in turn if the mapping has a sequence of keysyms.) When the
-   mouse button goes back up nothing is generated.
-
-   If you include modifier keys like Shift_L instead of key-press
-   immediately followed by key-release the state of the modifier key is
-   toggled (however the initial state of the modifier key is ignored.) So
-   to map the right button to type my name 'Karl Runge' I could use this:
-  -buttonmap 3-:Shift_L+k+Shift_L+a+r+l+space+Shift_L+r+Shift_L+u+n+g+e:
-
-   (yes, this is getting a little silly.)
-
-   BTW, Coming the other way around, if the machine you are sitting at
-   does not have a mouse wheel, but the remote machine does (or at least
-   has 5 buttons configured), this key remapping can be useful:
-  -remap Super_R-Button4,Menu-Button5
-
-   you just tap those two keys to get the mouse wheel scrolls (this is
-   more useful than the Up and Down arrow keys because a mouse wheel
-   "click" usually gives a multi-line scroll.)
-   [Keyboard Issues]
-
-   Q-87: How can I get my AltGr and Shift modifiers to work between
-   keyboards for different languages?
-
-   The option -modtweak should help here. It is a mode that monitors the
-   state of the Shift and AltGr Modifiers and tries to deduce the correct
-   keycode to send, possibly by sending fake modifier key presses and
-   releases in addition to the actual keystroke.
-
-   Update:  As of Jul/2004 -modtweak is now the default (use -nomodtweak
-   to get the old behavior.) This was done because it was noticed on
-   newer XFree86 setups even on bland "us" keyboards like "pc104 us"
-   XFree86 included a "ghost" key with both "<" and ">" it. This key does
-   not exist on the keyboard (see this FAQ for more info.) Without
-   -modtweak there was then an ambiguity in the reverse map keysym =>
-   keycode, making it so the "<" symbol could not be typed.
-
-   Also see the FAQ about the -xkb option for a more powerful method of
-   modifier tweaking for use on X servers with the XKEYBOARD extension.
-
-   When trying to resolve keyboard mapping problems, note that the
-   -debug_keyboard option prints out much info for every keystroke and so
-   can be useful debugging things.
-
-   Note that one user had a strange setup and none of the above helped.
-   His solution was to disable all of the above and use -nomodtweak. This
-   is the simplest form of keystroke insertion and it actually solved the
-   problem. Try it if the other options don't help.
-
-
-   Q-88: When I try to type a "<" (i.e. less than) instead I get ">"
-   (i.e. greater than)! Strangely, typing ">" works OK!!
-
-   Does your keyboard have a single key with both "<" and ">" on it? Even
-   if it doesn't, your X server may think your keyboard has such a key
-   (e.g. pc105 in the XF86Config file when it should be something else,
-   say pc104.)
-
-   Short Cut: Try the -xkb or -sloppy_keys options and see if that helps
-   the situation. The discussion below is a bit outdated (e.g. -modtweak
-   is now the default) but it is useful reference for various tricks and
-   so is kept.
-
-
-   The problem here is that on the Xserver where x11vnc is run there are
-   two keycodes that correspond to the "<" keysym. Run something like
-   this to see:
-
-  xmodmap -pk | egrep -i 'KeyCode|less|greater'
-  There are 4 KeySyms per KeyCode; KeyCodes range from 8 to 255.
-      KeyCode     Keysym (Keysym) ...
-       59         0x002c (comma)  0x003c (less)
-       60         0x002e (period) 0x003e (greater)
-       94         0x003c (less)   0x003e (greater)
-
-   That keycode 94 is the special key with both "<" and ">". When x11vnc
-   receives the "<" keysym over the wire from the remote VNC client, it
-   unfortunately maps it to keycode 94 instead of 59, and sends 94 to the
-   X server. Since Shift is down (i.e. you are Shifting the comma key),
-   the X server interprets this as Shifted-94, which is ">".
-
-   A workaround in the X server configuration is to "deaden" that special
-   key:
-
-  xmodmap -e "keycode 94 = "
-
-   However, one user said he had to do this:
-
-  xmodmap -e "keycode 94 = 0x002c 0x003c"
-
-   (If the numerical values are different for your setup, substitute the
-   ones that correspond to your display. The above xmodmap scheme can
-   often be used to work around other ambiguous keysym to keycode
-   mappings.)
-
-   Alternatively, here are some x11vnc options to try to work around the
-   problem:
-   -modtweak
-
-   and
-   -remap less-comma
-
-   These are convenient in that they do not modify the actual X server
-   settings. The former (-modtweak) is a mode that monitors the state of
-   the Shift and AltGr modifiers and tries to deduce the correct keycode
-   sequence to send. Since Jul/2004 -modtweak is now the default. The
-   latter (-remap less-comma) is an immediate remapping of the keysym
-   less to the keysym comma when it comes in from a client (so when Shift
-   is down the comma press will yield "<".)
-
-   See also the FAQ about the -xkb option as a possible workaround using
-   the XKEYBOARD extension.
-
-   Note that the -debug_keyboard option prints out much info for every
-   keystroke to aid debugging keyboard problems.
-
-
-   Q-89: Extra Character Inserted, E.g.: When I try to type a "<" (i.e.
-   less than) instead I get "<," (i.e. an extra comma.)
-
-   This is likely because you press "Shift" then "<" but then released
-   the Shift key before releasing the "<". Because of a keymapping
-   ambiguity the last event "< up" is interpreted as "," because that key
-   unshifted is the comma.
-
-   This extra character insertion will happen for other combinations of
-   characters: in general it can happen whenever the Shift key is
-   released early.
-
-   This should not happen in -xkb mode, because it works hard to resolve
-   the ambiguities. If you do not want to use -xkb, try the option
-   -sloppy_keys to attempt a similar type of algorithm.
-
-   One user had this problem for Italian and German keyboards with the
-   key containing ":" and "." When he typed ":" he would get an extra "."
-   inserted after the ":". The solution was -sloppy_keys.
-
-
-   Q-90: I'm using an "international" keyboard (e.g. German "de", or
-   Danish "dk") and the -modtweak mode works well if the VNC viewer is
-   run on a Unix/Linux machine with a similar keyboard.   But if I run
-   the VNC viewer on Unix/Linux with a different keyboard (e.g. "us") or
-   Windows with any keyboard, I can't type some keys like:   "@", "$",
-   "<", ">", etc. How can I fix this?
-
-   The problem with Windows is it does not seem to handle AltGr well. It
-   seems to fake it up by sending Control_L+Alt_R to applications. The
-   Windows VNC viewer sends those two down keystrokes out on the wire to
-   the VNC server, but when the user types the next key to get, e.g., "@"
-   the Windows VNC viewer sends events bringing the up the
-   Control_L+Alt_R keys, and then sends the "@" keysym by itself.
-
-   The Unix/Linux VNC viewer on a "us" keyboard does a similar thing
-   since "@" is the Shift of the "2" key. The keysyms Shift and "@" are
-   sent to the VNC server.
-
-   In both cases no AltGr is sent to the VNC server, but we know AltGr is
-   needed on the physical international keyboard to type a "@".
-
-   This all worked fine with x11vnc running with the -modtweak option (it
-   figures out how to adjust the Modifier keys (Shift or AltGr) to get
-   the "@".) However it fails under recent versions of XFree86 (and the
-   X.org fork.) These run the XKEYBOARD extension by default and make
-   heavy use of it to handle international keyboards.
-
-   To make a long story short, on these newer XFree86 setups the
-   traditional X keymap lookup x11vnc uses is no longer accurate. x11vnc
-   can't find the keysym "@" anywhere in the keymapping! (even though it
-   is in the XKEYBOARD extended keymapping.)
-
-   How to Solve: As of Jul/2004 x11vnc has two changes:
-     * -modtweak (tweak Modifier keys) is now the default (use
-       -nomodtweak to go back to the old way)
-     * there is a new option -xkb to use the XKEYBOARD extension API to
-       do the Modifier key tweaking.
-
-   The -xkb option seems to fix all of the missing keys: "@", "<", ">",
-   etc.: it is recommended that you try it if you have this sort of
-   problem. Let us know if there are any remaining problems (see the next
-   paragraph for some known problems.) If you specify the -debug_keyboard
-   (aka -dk) option twice you will get a huge amount of keystroke
-   debugging output (send it along with any problems you report.)
-
-   Update: as of Jun/2005 x11vnc will try to automatically enable -xkb if
-   it appears that would be beneficial (e.g. if it sees any of "@", "<",
-   ">", "[" and similar keys are mapped in a way that needs the -xkb to
-   access them.) To disable this automatic check use -noxkb.
-
-   Known problems:
-     * One user had to disable a "ghost" Mode_switch key that was causing
-       problems under -xkb. His physical AltGr key was bound to
-       ISO_Level3_Shift (which seems to be the XKEYBOARD way of doing
-       things), while there was a ghost key Mode_switch (which seems to
-       be obsolete) in the mapping as well. Both of these keysyms were
-       bound to Mod5 and x11vnc was unfortunately choosing Mode_switch.
-       From the x11vnc -xkb -dk -dk output it was noted that Mode_switch
-       was attached to keycode 93 (no physical key generates this
-       keycode) while ISO_Level3_Shift was attached to keycode 113. The
-       keycode skipping option was used to disable the ghost key:
-       -skip_keycodes 93
-     * In implementing -xkb we noticed that some characters were still
-       not getting through, e.g. "~" and "^". This is not really an
-       XKEYBOARD problem. What was happening was the VNC viewer was
-       sending the keysyms asciitilde and asciicircum to x11vnc, but on
-       the X server with the international keyboard those keysyms were
-       not mapped to any keys. So x11vnc had to skip them (Note: as of
-       May/2005 they are added by default see -add_keysyms below.)
-       The way these characters are typically entered on international
-       keyboards is by "dead" (aka "mute") keys. E.g. to enter "~" at the
-       physical display the keysym dead_tilde is pressed and released
-       (this usually involves holding AltGr down while another key is
-       pressed) and then space is pressed. (this can also be used get
-       characters with the "~" symbol on top, e.g. "ã" by typing "a"
-       instead of space.)
-       What to do? In general the VNC protocol has not really solved this
-       problem: what should be done if the VNC viewer sends a keysym not
-       recognized by the VNC server side? Workarounds can possibly be
-       created using the -remap x11vnc option:
-  -remap asciitilde-dead_tilde,asciicircum-dead_circumflex
-       etc. Use -remap filename if the list is long. Please send us your
-       workarounds for this problem on your keyboard. Perhaps we can have
-       x11vnc adjust automatically at some point. Also see the
-       -add_keysyms option in the next paragraph.
-       Update: for convenience "-remap DEAD" does many of these mappings
-       at once.
-     * To complement the above workaround using the -remap, an option
-       -add_keysyms was added. This option instructs x11vnc to bind any
-       unknown Keysyms coming in from VNC viewers to unused Keycodes in
-       the X server. This modifies the global state of the X server. When
-       x11vnc exits it removes the extra keymappings it created. Note
-       that the -remap mappings are applied first, right when the Keysym
-       is received from a VNC viewer, and only after that would
-       -add_keysyms, or anything else, come into play.
-       Update: -add_keysyms is now on by default. Use -noadd_keysyms to
-       disable.
-
-
-   Q-91: When typing I sometimes get double, triple, or more of my
-   keystrokes repeated. I'm sure I only typed them once, what can I do?
-
-   This may be due to an interplay between your X server's key autorepeat
-   delay and the extra time delays caused by x11vnc processing.
-
-   Short answer: disable key autorepeating by running the command "xset r
-   off" on the Xserver where x11vnc is run (restore via "xset r on") or
-   use the new (Jul/2004) -norepeat x11vnc option. You will still have
-   autorepeating because that is taken care of on your VNC viewer side.
-
-   Update: as of Dec/2004 -norepeat is now the default. Use -repeat to
-   disable it.
-
-   Details:
-   suppose you press a key DOWN and it generates changes in large regions
-   of the screen. The CPU and I/O work x11vnc does for the large screen
-   change could be longer than your X server's key autorepeat delay.
-   x11vnc may not get to processing the key UP event until after the
-   screen work is completed. The X server believes the key has been held
-   down all this time, and applies its autorepeat rules.
-
-   Even without inducing changes in large regions of the screen, this
-   problem could arise when accessing x11vnc via a dialup modem or
-   otherwise high latency link (e.g. > 250 ms latency.)
-
-   Look at the output of "xset q" for the "auto repeat delay" setting. Is
-   it low (e.g. < 300 ms)? If you turn off autorepeat completely: "xset r
-   off", does the problem go away?
-
-   The workaround is to manually apply "xset r off" and "xset r on" as
-   needed, or to use the -norepeat (which has since Dec/2004 been made
-   the default.) Note that with X server autorepeat turned off the VNC
-   viewer side of the connection will (nearly always) do its own
-   autorepeating so there is no big loss here, unless someone is also
-   working at the physical display and misses his autorepeating.
-
-
-   Q-92: The x11vnc -norepeat mode is in effect, but I still get repeated
-   keystrokes!!
-
-   Are you using x11vnc to log in to an X session via display manager?
-   (as described in this FAQ) If so, x11vnc is starting before your
-   session and it disables autorepeat when you connect, but then after
-   you log in your session startup (GNOME, KDE, ...) could be resetting
-   the autorepeat to be on. Or it could be something inside your desktop
-   trying to be helpful that decides to turn it back on.
-
-   x11vnc in -norepeat mode will by default reset autorepeat to off 2
-   times (to help get thru the session startup problem), but it will not
-   continue to battle with things turning autorepeat back on. It will
-   also turn autorepeat off whenever it goes from a state of zero clients
-   to one client. You can adjust the number of resets via "-norepeat N",
-   or use "-norepeat -1" to have it keep resetting it whenever autorepeat
-   gets turned back on when clients are connected.
-
-   In general you can manually turn autorepeating off by typing "xset r
-   off", or a using desktop utility/menu, or "x11vnc -R norepeat". If
-   something in your desktop is automatically turning it back on you
-   should figure out how to disable that somehow.
-
-
-   Q-93: After using x11vnc for a while, I find that I cannot type some
-   (or any) characters or my mouse clicks and drags no longer have any
-   effect, or they lead to strange effects. What happened?
-
-   Probably a modifier key, e.g. Control or Alt is "stuck" in a pressed
-   down state.
-
-   This happens for VNC in general by the following mechanism. Suppose on
-   the Viewer side desktop there is some hot-key to switch
-   desktops/rooms/spaces, etc. E.g. suppose Alt+LeftArrow moves to the
-   left desktop/room/space. Or suppose an Alt+hotkey combination
-   iconifies a window. This can leave the Alt key pressed down on the
-   remote side.
-
-   Consider the sequence that happens. The Alt_L key and then the
-   LeftArrow key go down. Since you are inside the viewer the Alt_L key
-   press is sent to the other side (x11vnc) and so it is pressed down in
-   the remote desktop as well. (by "Alt_L" we mean the Alt key on the
-   left-hand side of the keyboard.) Your local desktop (where the VNC
-   Viewer is running) then warps to the new desktop/room/space: Leaving
-   the Alt_L key still pressed down in the remote desktop.
-
-   If someone is sitting at the desktop, or when you return in the viewer
-   it may be very confusing because the Alt_L is still pressed down but
-   you (or the person sitting at the desktop) do not realize this.
-   Depending on which remote desktop (x11vnc side) is used, it can act
-   very strangely.
-
-   A quick workaround when you notice this is to press and release all of
-   the Alt, Shift, Control, Windows-Flag, modifier keys to free the
-   pressed one. You need to do this for both the left and right Shift,
-   Alt, Control, etc. keys to be sure.
-
-   Note that many VNC Viewers try to guard against this when they are
-   notified by the window system that the viewer app has "lost focus".
-   When it receives the "lost focus" event, the viewer sends VNC
-   Key-Release events for all modifier keys that are currently pressed
-   down. This does not always work, however, since it depends on how the
-   desktop manages these "warps". If the viewer is not notified it cannot
-   know it needs to release the modifiers.
-
-   You can also use the -clear_mods option to try to clear all of the
-   modifier keys at x11vnc startup. You will still have to be careful
-   that you do not leave the modifier key pressed down during your
-   session. It is difficult to prevent this problem from occurring (short
-   of using -remap to prevent sending all of the problem modifier keys,
-   which would make the destkop pretty unusable.)
-
-   During a session these x11vnc remote control commands can also help:
-   x11vnc -R clear_mods
-   x11vnc -R clear_keys
-   x11vnc -R clear_locks
-   x11vnc -R clear_all
-
-   A similar problem can occur if you accidentally press the Caps_Lock or
-   Num_Lock down. When these are locked on the remote side it can
-   sometimes lead to strange desktop behavior (e.g. cannot drag or click
-   on windows.) As above you may not notice this because the lock isn't
-   down on the local (Viewer) side. See this FAQ on lock keys problem.
-   These options may help avoid the problem: -skip_lockkeys and
-   -capslock. See also -clear_all.
-
-
-   Q-94: The machine where I run x11vnc has an AltGr key, but the local
-   machine where I run the VNC viewer does not. Is there a way I can map
-   a local unused key to send an AltGr? How about a Compose key as well?
-
-   Something like "-remap Super_R-Mode_switch" x11vnc option may work.
-   Note that Super_R is the "Right Windoze(tm) Flaggie" key; you may want
-   to choose another. The -debug_keyboard option comes in handy in
-   finding keysym names (so does xev(1).)
-
-   For Compose how about "-remap Menu-Multi_key" (note that Multi_key is
-   the official name for Compose.) To do both at the same time: "-remap
-   Super_R-Mode_switch,Menu-Multi_key" or use "-remap filename" to
-   specify remappings from a file.
-
-
-   Q-95: I have a Sun machine I run x11vnc on. Its Sun keyboard has just
-   one Alt key labelled "Alt" and two Meta keys labelled with little
-   diamonds. The machine where I run the VNC viewer only has Alt keys.
-   How can I send a Meta keypress? (e.g. emacs needs this)
-
-   Here are a couple ideas. The first one is to simply use xmodmap(1) to
-   adjust the Sun X server. Perhaps xmodmap -e "keysym Alt_L = Meta_L
-   Alt_L" will do the trick. (there are other ways to do it, one user
-   used: xmodmap -e "keycode 26 = Meta_L" for his setup.)
-
-   Since xmodmap(1) modifies the X server mappings you may not want to do
-   this (because it affects local work on that machine.) Something like
-   the -remap Alt_L-Meta_L to x11vnc may be sufficient for ones needs,
-   and does not modify the X server environment. Note that you cannot
-   send Alt_L in this case, maybe -remap Super_L-Meta_L would be a better
-   choice if the Super_L key is typically unused in Unix.
-
-
-   Q-96: Running x11vnc on HP-UX I cannot type "#" I just get a "3"
-   instead.
-
-   One user reports this problem on HP-UX Rel_B.11.23. The problem was
-   traced to a strange keyboard mapping for the machine (e.g. xmodmap -pk
-   output) that looked like:
-  ...
-  039  2                  at                 at               at
-  ...
-  047  3                  numbersign         numbersign       numbersign
-
-   and similar triple mappings (with two in the AltGr/Mode_switch group)
-   of a keysum to a single keycode.
-
-   Use the -nomodtweak option as a workaround. You can also use xmodmap
-   to correct these mappings in the server, e.g.:
-  xmodmap -e "keycode 47 = 3 numbersign"
-
-   Also, as of Feb/2007, set the environment variable MODTWEAK_LOWEST=1
-   (either in your shell or via "-env MODTWEAK_LOWEST=1" option) to
-   handle these mappings better.
-
-
-   Q-97: Can I map a keystroke to a mouse button click on the remote
-   machine?
-
-   This can be done directly in some X servers using AccessX and
-   Pointer_EnableKeys, but is a bit awkward. It may be more convenient to
-   have x11vnc do the remapping. This can be done via the -remap option
-   using the fake "keysyms" Button1, Button2, etc. as the "to" keys (i.e.
-   the ones after the "-")
-
-   As an example, consider a laptop where the VNC viewer is run that has
-   a touchpad with only two buttons. It is difficult to do a middle
-   button "paste" because (using XFree86/Xorg Emulate3Buttons) you have
-   to click both buttons on the touch pad at the same time. This
-   remapping:
-  -remap Super_R-Button2
-
-   maps the Super_R "flag" key press to the Button2 click, thereby making
-   X pasting a bit easier.
-
-   Note that once the key goes down, the button down and button up events
-   are generated immediately on the x11vnc side. When the key is released
-   (i.e. goes up) no events are generated.
-
-   Q-98: How can I get Caps_Lock to work between my VNC viewer and
-   x11vnc?
-
-   This is a little tricky because it is possible to get the Caps_Lock
-   state out of sync between your viewer-side machine and the x11vnc-side
-   X server. For best results, we recommend not ever letting the
-   Caps_Lock keypresses be processed by x11vnc. That way when you press
-   Caps_Lock in the viewer your local machine goes into the Caps_Lock on
-   state and sends keysym "A" say when you press "a". x11vnc will then
-   fake things up so that Shift is held down to generate "A". The
-   -skip_lockkeys option should help to accomplish this. For finer grain
-   control use something like: "-remap Caps_Lock-None".
-
-   Also try the -nomodtweak and -capslock options.
-
-   Another useful option that turns off any Lock keys on the remote side
-   at startup and end is the -clear_all option. During a session you can
-   run these remote control commands to modify the Lock keys:
-   x11vnc -R clear_locks
-   x11vnc -R clear_all
-
-   the former will try to unset any Lock keys, the latter will do same
-   and also try to make it so no key is pressed down (e.g. "stuck" Alt_L,
-   etc.)
-   [Screen Related Issues and Features]
-
-   Q-99: The remote display is larger (in number of pixels) than the
-   local display I am running the vncviewer on. I don't like the
-   vncviewer scrollbars, what I can do?
-
-   vncviewer has a option (usually accessible via F8 key or -fullscreen
-   option) for vncviewer to run in full screen, where it will
-   automatically scroll when the mouse is near the edge of the current
-   view. For quick scrolling, also make sure Backing Store is enabled on
-   the machine vncviewer is run on. (XFree86/Xorg disables it by default
-   for some reason, add Option "backingstore" to XF86Config on the
-   vncviewer side.)
-
-   BTW, contact me if you are having problems with vncviewer in
-   fullscreen mode with your window manager (i.e. no keyboard response.)
-   I have a workaround for vncviewer using XGrabServer().
-
-   There may also be scaling viewers out there (e.g. TightVNC or UltraVNC
-   on Windows) that automatically shrink or expand the remote framebuffer
-   to fit the local display. Especially for hand-held devices. See also
-   the next FAQ on x11vnc scaling.
-
-
-   Q-100: Does x11vnc support server-side framebuffer scaling? (E.g. to
-   make the desktop smaller.)
-
-   As of Jun/2004 x11vnc provides basic server-side scaling. It is a
-   global scaling of the desktop, not a per-client setting. To enable it
-   use the "-scale fraction" option. "fraction" can either be a floating
-   point number (e.g. -scale 0.75) or the alternative m/n fraction
-   notation (e.g. -scale 3/4.) Note that if fraction is greater than one
-   the display is magnified.
-
-   Extra resources (CPU, memory I/O, and memory) are required to do the
-   scaling. If the machine is slow where x11vnc is run with scaling
-   enabled, the interactive response can be unacceptable. OTOH, if run
-   with scaling on a fast machine the performance degradation is usually
-   not a big issue or even noticeable.
-
-   It may help to compile x11vnc with compiler option -O3 or -O4 to speed
-   up the scaling code. Set the CFLAGS env. var. before running
-   configure.
-
-   Also, if you just want a quick, rough "thumbnail" of the display you
-   can append ":nb" to the fraction to turn on "no blending" mode. E.g.:
-   "-scale 1/3:nb" Fonts will be difficult to read, but the larger
-   features will be recognizable. BTW, "no blending" mode is forced on
-   when scaling 8bpp PseudoColor displays (because blending an indexed
-   colormap is a bad idea and leads to random colors, use :fb to force it
-   on.)
-
-   One can also use the ":nb" with an integer scale factor (say "-scale
-   2:nb") to use x11vnc as a screen magnifier for vision impaired
-   applications. Since with integer scale factors the framebuffers become
-   huge and scaling operations time consuming, be sure to use ":nb" for
-   the fastest response.
-
-   In general for a scaled display if you are using a TightVNC viewer you
-   may want to turn off jpeg encoding (e.g. vncviewer -nojpeg host:0.)
-   There appears to be a noise enhancement effect, especially for regions
-   containing font/text: the scaling can introduce some pixel artifacts
-   that evidently causes the tight encoding algorithm to incorrectly
-   detect the regions as image data and thereby introduce additional
-   pixel artifacts due to the lossiness of the jpeg compression
-   algorithm. Experiment to see if -nojpeg vncviewer option improves the
-   readability of text when using -scale to shrink the display size. Also
-   note that scaling may actually slow down the transfer of text regions
-   because after being scaled they do not compress as well. (this can
-   often be a significant slowdown, e.g. 10X.)
-
-   Another issue is that it appears VNC viewers require the screen width
-   to be a multiple of 4. When scaling x11vnc will round the width to the
-   nearest multiple of 4. To disable this use the ":n4" sub option (like
-   ":nb" in the previous paragraph; to specify both use a comma:
-   ":nb,n4", etc.)
-
-   If one desires per-client scaling for something like 1:1 from a
-   workstation and 1:2 from a smaller device (e.g. handheld), currently
-   the only option is to run two (or more) x11vnc processes with
-   different scalings listening on separate ports (-rfbport option, etc.)
-
-   Update: As of May/2006 x11vnc also supports the UltraVNC server-side
-   scaling. This is a per-client scaling by factors 1/2, 1/3, ... and so
-   may be useful for PDA's ("-scale 1/2", etc. will give similar results
-   except that it applies to all clients.) You may need to supply
-   "-rfbversion 3.6" for this to be recognized by UltraVNC viewers.
-
-   BTW, whenever you run two or more x11vnc's on the same X display and
-   use the GUI, then to avoid all of the x11vnc's simultaneously
-   answering the gui you will need to use something like "-connect file1
-   -gui ..." with different connect files for each x11vnc you want to
-   control via the gui (or remote-control.) The "-connect file1" usage
-   gives separate communication channels between a x11vnc process and the
-   gui process. Otherwise they all share the same X property channels:
-   VNC_CONNECT and X11VNC_REMOTE.
-
-   Update: As of Mar/2005 x11vnc now scales the mouse cursor with the
-   same scale factor as the screen. If you don't want that, use the
-   "-scale_cursor frac" option to set the cursor scaling to a different
-   factor (e.g. use "-scale_cursor 1" to keep the cursor at its natural
-   unscaled size.)
-
-
-   Q-101: Does x11vnc work with Xinerama? (i.e. multiple monitors joined
-   together to form one big, single screen.)
-
-   Yes, it should generally work because it simply polls the big
-   effective screen.
-
-   If the viewing-end monitor is not as big as the remote Xinerama
-   display, then the vncviewer scrollbars, etc, will have to be used to
-   pan across the large area. However one user started two x11vnc's, one
-   with "-clip 1280x1024+0+0" and the other with "-clip 1280x1024+1280+0"
-   to split the big screen into two and used two VNC viewers to access
-   them.
-
-   As of Jun/2008: Use "-clip xinerama0" to clip to the first xinerama
-   sub-screen (if xinerama is active.) xinerama1 for the 2nd sub-screen,
-   etc. This way you don't need to figure out the WxH+X+Y of the desired
-   xinerama sub-screen. screens are sorted in increasing distance from
-   the (0,0) origin (I.e. not the Xserver's order.)
-
-   There are a couple potential issues with Xinerama however. If the
-   screen is not rectangular (e.g. 1280x1024 and 1024x768 monitors joined
-   together), then there will be "non-existent" areas on the screen. The
-   X server will return "garbage" image data for these areas and so they
-   may be distracting to the viewer. The -blackout x11vnc option allows
-   you to blacken-out rectangles by manually specifying their WxH+X+Y
-   geometries. If your system has the libXinerama library, the -xinerama
-   x11vnc option can be used to have it automatically determine the
-   rectangles to be blackened out. (Note on 8bpp PseudoColor displays the
-   fill color may not be black.) Update: -xinerama is now on by default.
-
-   Some users have reported that the mouse does not behave properly for
-   their Xinerama display: i.e. the mouse cannot be moved to all regions
-   of the large display. If this happens try using the -xwarppointer
-   option. This instructs x11vnc to fake mouse pointer motions using the
-   XWarpPointer function instead of the XTestFakeMotionEvent XTEST
-   function. (This may be due to a bug in the X server for XTEST when
-   Xinerama is enabled.) Update: As of Dec/2006 -xwarppointer will be
-   applied automatically if Xinerama is detected. To disable use:
-   -noxwarppointer
-
-
-   Q-102: Can I use x11vnc on a multi-headed display that is not Xinerama
-   (i.e. separate screens :0.0, :0.1, ... for each monitor)?
-
-   You can, but it is a little bit awkward: you must start separate
-   x11vnc processes for each screen, and on the viewing end start up
-   separate VNC viewer processes connecting to them. e.g. on the remote
-   end:
-  x11vnc -display :0.0 -bg -q -rfbport 5900
-  x11vnc -display :0.1 -bg -q -rfbport 5901
-
-   (this could be automated in the display manager Xsetup for example)
-   and then on the local machine where you are sitting:
-  vncviewer somehost:0 &
-  vncviewer somehost:1 &
-
-   Note: if you are running on Solaris 8 or earlier you can easily hit up
-   against the maximum of 6 shm segments per process (for Xsun in this
-   case) from running multiple x11vnc processes. You should modify
-   /etc/system as mentioned in another FAQ to increase the limit. It is
-   probably also a good idea to run with the -onetile option in this case
-   (to limit each x11vnc to 3 shm segments), or even -noshm to use no shm
-   segments.
-
-
-   Q-103: Can x11vnc show only a portion of the display? (E.g. for a
-   special purpose application or a very large screen.)
-
-   As of Mar/2005 x11vnc has the "-clip WxH+X+Y" option to select a
-   rectangle of width W, height H and offset (X, Y). Thus the VNC screen
-   will be the clipped sub-region of the display and be only WxH in size.
-   One user used -clip to split up a large Xinerama screen into two more
-   managable smaller screens.
-
-   This also works to view a sub-region of a single application window if
-   the -id or -sid options are used. The offset is measured from the
-   upper left corner of the selected window.
-
-
-   Q-104: Does x11vnc support the XRANDR (X Resize, Rotate and
-   Reflection) extension? Whenever I rotate or resize the screen x11vnc
-   just seems to crash.
-
-   As of Dec/2004 x11vnc supports XRANDR. You enable it with the -xrandr
-   option to make x11vnc monitor XRANDR events and also trap X server
-   errors if the screen change occurred in the middle of an X call like
-   XGetImage. Once it traps the screen change it will create a new
-   framebuffer using the new screen.
-
-   If the connected vnc viewers support the NewFBSize VNC extension
-   (Windows TightVNC viewer and RealVNC 4.0 windows and Unix viewers do)
-   then the viewer will automatically resize. Otherwise, the new
-   framebuffer is fit as best as possible into the original viewer size
-   (portions of the screen may be clipped, unused, etc.) For these
-   viewers you can try the -padgeom option to make the region big enough
-   to hold all resizes and rotations. We have fixed this problem for the
-   TightVNC Viewer on Unix: SSVNC
-
-   If you specify "-xrandr newfbsize" then vnc viewers that do not
-   support NewFBSize will be disconnected before the resize. If you
-   specify "-xrandr exit" then all will be disconnected and x11vnc will
-   terminate.
-
-
-   Q-105: Independent of any XRANDR, can I have x11vnc rotate and/or
-   reflect the screen that the VNC viewers see? (e.g. for a handheld
-   whose screen is rotated 90 degrees.)
-
-   As of Jul/2006 there is the -rotate option allow this. E.g's: "-rotate
-   +90", "-rotate -90", "-rotate x", etc.
-
-
-   Q-106: Why is the view in my VNC viewer completely black? Or why is
-   everything flashing around randomly?
-
-   See the next FAQ for a possible explanation.
-
-
-   Q-107: I use Linux Virtual Terminals (VT's) to implement 'Fast User
-   Switching' between users' sessions (e.g. Betty is on Ctrl-Alt-F7,
-   Bobby is on Ctrl-Alt-F8, and Sid is on Ctrl-Alt-F1: they use those
-   keystrokes to switch between their sessions.)   How come the view in a
-   VNC viewer connecting to x11vnc is either completely black or
-   otherwise all messed up unless the X session x11vnc is attached to is
-   in the active VT?
-
-   This seems to have to do with how applications (the X server processes
-   in this case) must "play nicely" if they are not on the active VT
-   (sometimes called VC for virtual console.) That is, they should not
-   read from the keyboard or mouse or manage the video display unless
-   they have the active VT. Given that it appears the XGetImage() call
-   must ultimately retrieve the framebuffer data from the video hardware
-   itself, it would make sense x11vnc's polling wouldn't work unless the
-   X session had active control of the VT.
-
-   There does not seem to be an easy way to work around this. Even xwd(1)
-   doesn't work in this case (try it.) Something would need to be done at
-   a lower level, say in the XFree86/Xorg X server. Also, using the
-   Shadow Framebuffer (a copy of the video framebuffer is kept in main
-   memory) does not appear to fix the problem.
-
-   If no one is sitting at the workstation and you just want to remotely
-   switch the VT over to the one associated with your X session (so
-   x11vnc can poll it correctly), one can use the chvt(1) command, e.g.
-   "chvt 7" for VT #7.
-
-
-   Q-108: I am using x11vnc where my local machine has "popup/hidden
-   taskbars" and the remote display where x11vnc runs also has
-   "popup/hidden taskbars" and they interfere and fight with each other.
-   What can I do?
-
-   When you move the mouse to the edge of the screen where the popups
-   happen, the taskbars interfere with each other in strange ways. This
-   sometimes happens where the local machine is GNOME or Mac OS X and the
-   remote machine is GNOME. Is there a way to temporarily disable one or
-   both of these magic desktop taskbars?
-
-   One x11vnc user suggests: it should be straightforward to right mouse
-   click on the task bar panel, and uncheck "enable auto-hide" from the
-   panel properties dialog box. This will make the panel always visible.
-
-   Q-109: Help! x11vnc and my KDE screensaver keep switching each other
-   on and off every few seconds.
-
-   This is a new (Jul/2006) problem seen, say, on the version of KDE that
-   is shipped with SuSE 10.1. It is not yet clear what is causing this...
-   If you move the mouse through x11vnc the screensaver shuts off like it
-   should but then a second or two after you stop moving the mouse the
-   screensaver snaps back on.
-
-   This may be a bug in kdesktop_lock. For now the only workaround is to
-   disable the screensaver. You can try using another one such as
-   straight xscreensaver (see the instructions here for how to disable
-   kdesktop_lock.) If you have more info on this or see it outside of KDE
-   please let us know.
-
-   Update: It appears this is due to kdesktop_lock enabling the screen
-   saver when the Monitor is in DPMS low-power state (e.g. standby,
-   suspend, or off.) In Nov/2006 the x11vnc -nodpms option was added as a
-   workaround. Normally it is a good thing that the monitor powers down
-   (since x11vnc can still poll the framebuffer in this state), but if
-   you experience the kdesktop_lock problem you can specify the "-nodpms"
-   option to keep the Monitor out of low power state while VNC clients
-   are connected. This is basically the same as typing "xset dpms force
-   on" periodically. (if you don't want to do these things just disable
-   the screensaver.) Feel free to file a bug against kdesktop_lock with
-   KDE.
-
-   Q-110: I am running the compiz 3D window manager (or beryl, MythTv,
-   Google Earth, or some other OpenGL app) and I do not get screen
-   updates in x11vnc.
-
-   This appears to be because the 3D OpenGL/GLX hardware screen updates
-   do not get reported via the XDAMAGE mechanism. So this is a bug in
-   compiz/beryl or XDAMAGE/Xorg or the (possibly 3rd party) video card
-   driver.
-
-   As a workaround apply the -noxdamage option. As of Feb/2007 x11vnc
-   will try to autodetect the problem and disable XDAMAGE if is appears
-   to be missing a lot of updates. But if you know you are using compiz
-   you might as well always supply -noxdamage. Thanks to this user who
-   reported the problem and discovered the workaround.
-
-   A developer for MiniMyth reports that the 'alphapulse' tag of the
-   theme G.A.N.T. can also cause problems, and should be avoided when
-   using VNC.
-
-   Please report a bug or complaint to Beryl/Compiz and/or Xorg about
-   this: running x11vnc with -noxdamage disables a nice improvement in
-   responsiveness (especially for typing) and also leads to unnecessary
-   CPU and memory I/O load due to the extra polling.
-
-   Update: as of May/2010 NVIDIA may have fixed this problem in their
-   proprietary drivers. See the NVIDIA Release Notes. (look for
-   'x11vnc'.)
-
-   Q-111: Can I use x11vnc to view my VMWare session remotely?
-
-   Yes, since VMWare usually runs as an X application you can view it via
-   x11vnc in the normal way.
-
-   Note that VMWare has several viewing modes:
-     * Normal X application window  (with window manager frame)
-     * Quick-Switch mode  (with no window manager frame)
-     * Fullscreen mode
-
-   The way VMWare does Fullscreen mode on Linux is to display the Guest
-   desktop in a separate Virtual Terminal (e.g. VT 8) (see this FAQ on
-   VT's for background.) Unfortunately, this Fullscreen VT is not an X
-   server. So x11vnc cannot access it (however, see this discussion of
-   -rawfb for a possible workaround.) x11vnc works fine with "Normal X
-   application window" and "Quick-Switch mode" because these use X.
-
-   Update: It appears the in VMWare 5.x the Fullscreen mode is X, so
-   x11vnc access does work.
-
-   One user reports he left his machine with VMWare in the Fullscreen
-   mode, and even though his X session wasn't in the active VT, he could
-   still connect x11vnc to the X session and pass the keystrokes Ctrl-Alt
-   (typing "blind") to the VMWare X app. This induced VMWare to switch
-   out of Fullscreen into Normal X mode and he could continue working in
-   the Guest desktop remotely.
-
-
-   Aside: Sometimes it is convenient (for performance, etc.) to start
-   VMWare in its own X session using startx(1). This can be used to have
-   a minimal window manger (e.g. twm or even no window manager), to
-   improve response. One can also cut the display depth (e.g. to 16bpp)
-   in this 2nd X session to improve video performance. This 2nd X session
-   emulates Fullscreen mode to some degree and can be viewed via x11vnc
-   as long as the VMWare X session is in the active VT.
-
-   Also note that with a little bit of playing with "xwininfo -all
-   -children" output one can extract the (non-toplevel) window-id of the
-   of the Guest desktop only when VMWare is running as a normal X
-   application. Then one can export just the guest desktop (i.e. without
-   the VMWare menu buttons) by use of the -id windowid option. The
-   caveats are the X session VMWare is in must be in the active VT and
-   the window must be fully visible, so this mode is not terribly
-   convenient, but could be useful in some circumstances (e.g. running
-   VMWare on a very powerful server machine in a server room that happens
-   to have a video card, (but need not have a monitor, Keyboard or
-   mouse).)
-
-
-
-   [Exporting non-X11 devices via VNC]
-
-   Q-112: Can non-X devices (e.g. a raw framebuffer) be viewed (and even
-   controlled) via VNC with x11vnc?
-
-   As of Apr/2005 there is support for this. Two options were added:
-   "-rawfb string" (to indicate the raw frame buffer device, file, etc.
-   and its parameters) and "-pipeinput command" (to provide an external
-   program that will inject or otherwise process mouse and keystroke
-   input.) Some useful -pipeinput schemes, VID, CONSOLE, and UINPUT, have
-   since been built into x11vnc for convenience.
-
-   This non-X mode for x11vnc is somewhat experimental because it is so
-   removed in scope from the intended usage of the tool. Incomplete
-   attempt is made to make all of the other options consistent with non-X
-   framebuffer polling. So all of the X-related options (e.g.
-   -add_keysyms, -xkb) are just ignored or may cause an error if used. Be
-   careful applying such an option via remote control.
-
-   The format for the -rawfb string is:
-    -rawfb <type>:<object>@<W>x<H>x<bpp>[-<BPL>][:<R>/<G>/<B>][+<offset>]
-
-   There are also some useful aliases (e.g. "console".) Some examples:
-    -rawfb shm:210337933@800x600x32:ff/ff00/ff0000
-
-    -rawfb map:/dev/fb0@1024x768x16
-
-    -rawfb map:/tmp/Xvfb_screen0@640x480x8+3232
-
-    -rawfb file:/tmp/my.pnm@250x200x24+37
-
-    -rawfb file:/dev/urandom@128x128x8
-
-    -rawfb snap:/dev/video0@320x240x24 -24to32
-
-    -rawfb console
-
-    -rawfb vt2
-
-    -rawfb video
-
-    -rawfb setup:mycmd.sh
-
-   So the type can be "shm" for shared memory objects, and "map" or
-   "file" for file objects. "map" uses mmap(2) to map the file into
-   memory and is preferred over "file" (that uses the slower lseek(2)
-   access method.) Only use file if map isn't working. BTW, "mmap" is an
-   alias for "map" and if you do not supply a type and the file exists,
-   map is assumed (see the -help output and below for some exceptions to
-   this.) The "snap:" setting applies the -snapfb option with "file:"
-   type reading (this is useful for exporting webcams or TV tuner video;
-   see the next FAQ for more info.)
-
-   Also, if the string is of the form "setup:cmd" then cmd is run and the
-   first line of its output retrieved and used as the rawfb string. This
-   allows initializing the device, determining WxHxB, etc.
-
-   The object will be the numerical shared memory id for the case of shm.
-   The idea here is some other program has created this shared memory
-   segment and periodically updates it with new framebuffer data. x11vnc
-   polls the area for changes. See shmat(2) and ipcs(8) for more info.
-   The ipcs command will list current shared memory segments on the
-   system. Sometimes you can snoop on a program's framebuffer it did not
-   expect you would be polling!
-
-   The object will be the path to the regular or character special file
-   for the cases of map and file. The idea here is that in the case of a
-   regular file some other program is writing/updating framebuffer image
-   data to it. In the case of a character special (e.g. /dev/fb0) it is
-   the kernel that is "updating" the framebuffer data.
-
-   In most cases x11vnc needs to be told the width, height, and number of
-   bits per pixel (bpp) of the framebuffer. This is the @WxHxB field. For
-   the case of the Linux framebuffer device, /dev/fb0, the fbset(8) may
-   be of use (but may not always be accurate for what is currently
-   viewable.) In general some guessing may be required, especially for
-   the bpp. Update: in "-rawfb console" mode x11vnc will use the linuxfb
-   API to try to guess (it is still not always accurate.) Also try
-   "-rawfb vtN" (on x11vnc 0.9.7 and later) for the N-th Linux text
-   console (aka virtual terminal.) If the number of Bytes Per Line is not
-   WxHxB/8 (i.e. the framebuffer lines are padded) you can specify this
-   information after WxHxB via "-BPL", e.g. @800x600x16-2048
-
-   Based on the bpp x11vnc will try to guess the red, green, and blue
-   masks (these indicate which bits correspond to each color.) It if gets
-   it wrong you can specify them manually via the optional ":R/G/B"
-   field. E.g. ":0xff0000/0x00ff00/0x0000ff" (this is the default for
-   32bpp.)
-
-   Finally, the framebuffer may not begin at the beginning of the memory
-   object, so use the optional "+offset" parameter to indicate where the
-   framebuffer information starts. So as an example, the Xvfb virtual
-   framebuffer has options -shmem and -fbdir for exporting its virtual
-   screen to either shm or a mapped file. The format of these is XWD and
-   so the initial header should be skipped. BTW, since XWD is not
-   strictly RGB the view will only be approximate, but usable. Of course
-   for the case of Xvfb x11vnc can poll it much better via the X API, but
-   you get the idea.
-
-   By default in -rawfb mode x11vnc will actually close any X display it
-   happened to open. This is basically to shake out bugs (e.g it will
-   crash rather than mysteriously interacting with the X display.) If you
-   want x11vnc to keep the X display open while polling the raw
-   framebuffer prefix a "+" sign at the beginning of the string (e.g.
-   +file:/dev/urandom@64x64x8) This could be convenient for keeping the
-   remote control channel active (it uses X properties.) The "-connect
-   /path/to/file" mechanism could also be used for remote control to
-   avoid the X property channel. Rare usage, but if you also supply
-   -noviewonly in this "+" mode then the mouse and keyboard input are
-   still sent to the X display, presumably for doing something amusing
-   with /dev/fb...
-
-   Interesting Devices:. Here are some aliases for interesting device
-   files that can be polled via -rawfb:
-   -rawfb console               /dev/fb0        Linux Console
-   -rawfb vt2                   /dev/vcsa2      Linux Console (e.g. virtual ter
-minal #2)
-   -rawfb video                 /dev/video0     Video4Linux Capture device
-   -rawfb rand                  /dev/urandom    Random Bytes
-   -rawfb null                  /dev/zero       Zero Bytes (black screen)
-
-   The Linux console, /dev/fb0, etc needs to have its driver enabled in
-   the kernel. Some of the drivers are video card specific and
-   accelerated. The console is either the Text consoles (usually
-   tty1-tty6), or X graphical display (usually starting at tty7.) In
-   addition to the text console other graphical ones may be viewed and
-   interacted with as well, e.g. DirectFB or SVGAlib apps, VMWare non-X
-   fullscreen, or Qt-embedded apps (PDAs/Handhelds.) By default the
-   pipeinput mechanisms UINPUT and CONSOLE (keystrokes only) are
-   automatically attempted in this mode under "-rawfb console".
-
-   The Video4Linux Capture device, /dev/video0, etc is either a Webcam or
-   a TV capture device and needs to have its driver enabled in the
-   kernel. See this FAQ for details. If specified via "-rawfb Video" then
-   the pipeinput method "VID" is applied (it lets you change video
-   parameters dynamically via keystrokes.)
-
-   The last two, /dev/urandom and /dev/zero are just for fun, but are
-   also useful in testing.
-
-
-   All of the above -rawfb options are just for viewing the raw
-   framebuffer (although some of the aliases do imply keystroke and mouse
-   pipeinput methods.) That may be enough for certain applications of
-   this feature (e.g. suppose a video camera mapped its framebuffer into
-   memory and you just wanted to look at it via VNC.)
-   To handle the pointer and keyboard input from the viewer users the
-   "-pipeinput cmd" option was added to indicate a helper program to
-   process the user input. The input is streamed to it and looks
-   something like this:
-   Pointer 1 205 257 0 None
-   Pointer 1 198 253 0 None
-   Pointer 1 198 253 1 ButtonPress-1
-   Pointer 1 198 253 0 ButtonRelease-1
-   Pointer 1 198 252 0 None
-   Keysym 1 1 119 w KeyPress
-   Keysym 1 0 119 w KeyRelease
-   Keysym 1 1 65288 BackSpace KeyPress
-   Keysym 1 0 65288 BackSpace KeyRelease
-   Keysym 1 1 112 p KeyPress
-   Keysym 1 0 112 p KeyRelease
-
-   Run "-pipeinput tee:/bin/cat" to get a description of the format. Note
-   that the -pipeinput option is independent of -rawfb mode and so may
-   have some other interesting uses. The "tee:" prefix means x11vnc will
-   both process the user input and pipe it to the command. The default is
-   to just pipe it to the -pipeinput command.
-
-   Note the -pipeinput helper program could actually control the raw
-   framebuffer. In the libvncserver CVS a simple example program
-   x11vnc/misc/slide.pl is provided that demonstrates a simple jpeg
-   "slideshow" application. Also the builtin "-pipeinput VID" mode does
-   this for webcams and TV capture devices (/dev/video0.)
-
-   The -pipeinput program is run with these environment variables set:
-   X11VNC_PID, X11VNC_PROG, X11VNC_CMDLINE, X11VNC_RAWFB_STR to aid its
-   knowing what is up.
-
-   Another example provided in libvncserver CVS is a script to inject
-   keystrokes into the Linux console (e.g. the virtual consoles:
-   /dev/tty1, /dev/tty2, etc) in x11vnc/misc/vcinject.pl. It is based on
-   the vncterm/LinuxVNC.c program also in the libvncserver CVS. So to
-   view and interact with VT #2 (assuming it is the active VT) one can
-   run something like:
-  x11vnc -rawfb map:/dev/fb0@1024x768x16 -pipeinput './vcinject.pl 2'
-
-   This assumes your Linux framebuffer device (/dev/fb0) is properly
-   configured. See fbset(8) and other documentation. Try
-   "file:/dev/fb0@WxHxB" as a last resort. Starting with x11vnc 0.8.1,
-   the above VT injection is built in, as well as WxHxB determination.
-   Just use something like:
-  x11vnc -rawfb console
-
-   this will try to guess the active virtual console (via /dev/tty0) and
-   also the /dev/fb0 WxHxB and rgb masks automatically. Use, e.g.,
-   "-rawfb console3" to force the VT number. This input method can be
-   used generally via "-pipeinput CONSOLE". Also starting with x11vnc
-   0.8.2 the "-pipeinput UINPUT" mode is tried first (it does both
-   keyboard and mouse input) and then falls back to CONSOLE mode if it is
-   not available. Here is the -help output for this mode:
-
-     If the rawfb string begins with "console" the framebuffer device
-     /dev/fb0 is opened (this requires the appropriate kernel modules to
-     be installed) and so is /dev/tty0. The latter is used to inject
-     keystrokes (not all are supported, but the basic ones are.) You
-     will need to be root to inject keystrokes. /dev/tty0 refers to the
-     active VT, to indicate one explicitly, use "console2", etc. using
-     the VT number.
-
-     If the Linux version seems to be 2.6 or later and the "uinput"
-     module appears to be present, then the uinput method will be used
-     instead of /dev/ttyN. uinput allows insertion of BOTH keystrokes
-     and mouse input and so it preferred when accessing graphical (e.g.
-     Qt-embedded) linux console apps. See -pipeinput UINPUT below for
-     more information on this mode (you may want to also use the
-     -nodragging and -cursor none options.) Use "console0", etc or
-     -pipeinput CONSOLE to force the /dev/ttyN method.
-
-     Note you can change VT remotely using the chvt(1) command.
-     Sometimes switching out and back corrects the framebuffer state.
-
-     To skip input injecting entirely use "consolex".
-
-     The string "/dev/fb0" (1, etc) can be used instead of "console".
-     This can be used to specify a different framebuffer device, e.g.
-     /dev/fb1. As a shortcut the "/dev/" can be dropped. If the name is
-     something nonstandard, use "console:/dev/foofb"
-
-     If you do not want x11vnc to guess the framebuffer's WxHxB and
-     masks automatically (sometimes the kernel gives inaccurate
-     information), specify them with a @WxHxB at the end of the string.
-
-   The above is just an example of what can be done. Note that if you
-   really want to view and interact with the Linux Text console it is
-   better to use the more accurate and faster LinuxVNC program. The
-   advantage x11vnc -rawfb might have is that it can allow interaction
-   with a non-text application, e.g. one based on SVGAlib or Qt-embedded
-   Also, for example the VMWare Fullscreen mode is actually viewable
-   under -rawfb and can be interacted with if uinput is enabled.
-
-   If the Linux uinput driver is available then full keystroke and mouse
-   input into the Linux console can be performed. You may be able to
-   enable uinput via commands like these:
-  modprobe uinput
-  mknod /dev/input/uinput c 10 223
-
-   The -rawfb and -pipeinput features are intended to help one creatively
-   "get out of a jam" (say on a legacy or embedded device) where X is
-   absent or doesn't work properly. Feedback and bug reports are welcome.
-   For more control and less overhead use libvncserver in your own C
-   program that passes the framebuffer to libvncserver.
-
-
-   Q-113: Can I export the Linux Console (Virtual Terminals) via VNC
-   using x11vnc?
-
-   Yes, you may need to be root to access the devices that make up the
-   linux console.
-
-   To access the active Linux console via the computer's framebuffer try
-   something like:
-  x11vnc -rawfb console
-  x11vnc -rawfb console2
-
-   These will try to access the framebuffer through /dev/fb (or /dev/fb0,
-   etc.) and if it succeeds it will show any text or graphics that is
-   currently displayed. Keystrokes will be injected via the device
-   /dev/tty0 (to force an explicit virtual terminal append a number, e.g.
-   "console2" to select /dev/tty2.)
-
-   If your Linux system does not have a framebuffer device (/dev/fb) you
-   can get one by adding, e.g., vga=0x31B boot parameter. This enables
-   the VGA framebuffer device at 1280x1024x24. 0x317 gives 1024x768x16,
-   etc. You can also enable a Linux framebuffer device by modprobing a
-   framebuffer driver specific to your video card.
-
-   Note that this "-rawfb console" mode shows the contents of the
-   hardware framebuffer, and so will show whatever is on the screen. It
-   has no concept of Virtual Terminals WRT what there is to view, it
-   always shows the active virtual terminal.
-
-   Another mode is specific to the Linux text Virtual Terminals, it shows
-   their text and colors (but no graphics) regardless of whether it is
-   the active VT or not. It is available on x11vnc 0.9.7 and later.
-   Enable this mode like this:
-  x11vnc -rawfb vt
-  x11vnc -rawfb vt2
-
-   The former will select the active one, the latter the 2nd VT. x11vnc
-   implements this mode by opening the current console text file
-   "/dev/vcsa2" instead of "/dev/fb". In this way it provides the basic
-   functionality of the LibVNCServer LinuxVNC program.
-
-   The vt mode can be a useful way to try to get a machine's X server
-   working remotely, e.g. you edit /etc/X11/xorg.conf and then type
-   startx (or similar, e.g. gdm) in the virtual terminal. A 2nd x11vnc
-   could be used to see if the X server is now working correctly.
-
-   Q-114: Can I export via VNC a Webcam or TV tuner framebuffer using
-   x11vnc?
-
-   Yes, this is possible to some degree with the -rawfb option. There is
-   no X11 involved: snapshots from the video capture device are used for
-   the screen image data. See the previous FAQ on -rawfb for background.
-   For best results, use x11vnc version 0.8.1 or later.
-
-   Roughly, one would do something like this:
-  x11vnc -rawfb snap:/dev/video@320x240x32
-
-   This requires that the system allows simple read(2) access to the
-   video device. This is true for video4Linux on Linux kernel 2.6 and
-   later (it won't work for 2.4, you'll need a separate program to
-   snapshot to a file that you point -rawfb to; ask me if it is not clear
-   what to do.)
-
-   The "snap:" enforces -snapfb mode which appears to be necessary. The
-   read pointer for video capture devices cannot be repositioned (which
-   would be needed for scanline polling), but you can read a full frame
-   of data from the device.
-
-   On Linux, if the Video4Linux API is present or the v4l-info(1) program
-   (related to xawtv) exists in in PATH, then x11vnc can be instructed to
-   try it to determine the -rawfb WxHxB parameters for you automatically.
-   In this case one would just type:
-  x11vnc -rawfb video
-
-   or "-rawfb video1" for the 2nd video device, etc.
-
-   x11vnc has also been extended to use the Video4Linux API over v4l-info
-   if it is available at build time. This enables setting parameters
-   (e.g. size and brightness) via x11vnc. See the description below.
-   Without Video4Linux you will need to initialize the settings of the
-   video device using something like xawtv or spcaview (and then hope the
-   settings persist until x11vnc reopens the device.)
-
-   Many video4linux drivers tend to set the framebuffer to be 24bpp (as
-   opposed to 32bpp.) Since this can cause problems with VNC viewers,
-   etc, the -24to32 option will be automatically imposed when in 24bpp.
-
-   Note that by its very nature, video capture involves rapid change in
-   the framebuffer. This is especially true for cameras where slight
-   wavering in brightness is always happening. This can lead to much
-   network bandwidth consumption for the VNC traffic and also local CPU
-   and I/O resource usage. You may want to experiment with "dialing down"
-   the framerate via the -wait, -slow_fb, or -defer options. Decreasing
-   the window size and bpp also helps.
-
-
-   Setting Camera/Tuner parameters via x11vnc:
-
-   There is also some support for setting parameters of the capture
-   device. This is done via "-rawfb video:<settings>". This could be
-   useful for unattended startup at boottime, etc. Here is the -help
-   description:
-
-     A more sophisticated video device scheme allows initializing the
-     device's settings using:
-
-           -rawfb video:<settings>
-
-     The prefix could also be, as above, e.g. "video1:" to specify the
-     device file. The v4l API must be available for this to work.
-     Otherwise, you will need to try to initialize the device with an
-     external program, e.g. xawtv, spcaview, and hope they persist when
-     x11vnc re-opens the device.
-
-     <settings> is a comma separated list of key=value pairs. The
-     device's brightness, color, contrast, and hue can be set to
-     percentages, e.g. br=80,co=50,cn=44,hu=60.
-
-     The device filename can be set too if needed (if it does not start
-     with "video"), e.g. fn=/dev/qcam.
-
-     The width, height and bpp of the framebuffer can be set via, e.g.,
-     w=160,h=120,bpp=16.
-
-     Related to the bpp above, the pixel format can be set via the
-     fmt=XXX, where XXX can be one of: GREY, HI240, RGB555, RGB565,
-     RGB24, and RGB32 (with bpp 8, 8, 16, 16, 24, and 32 respectively.)
-     See http://www.linuxtv.org for more info (V4L api.)
-
-     For TV/rf tuner cards one can set the tuning mode via tun=XXX where
-     XXX can be one of PAL, NTSC, SECAM, or AUTO.
-
-     One can switch the input channel by the inp=XXX setting, where XXX
-     is the name of the input channel (Television, Composite1, S-Video,
-     etc.) Use the name that is in the information about the device that
-     is printed at startup.
-
-     For input channels with tuners (e.g. Television) one can change
-     which station is selected by the sta=XXX setting. XXX is the
-     station number. Currently only the ntsc-cable-us (US cable)
-     channels are built into x11vnc. See the -freqtab option below to
-     supply one from xawtv. If XXX is greater than 500, then it is
-     interpreted as a raw frequency in KHz.
-
-     Example:
-
-     -rawfb video:br=80,w=320,h=240,fmt=RGB32,tun=NTSC,sta=47
-
-     one might need to add inp=Television too for the input channel to
-     be TV if the card doesn't come up by default in that one.
-
-     Note that not all video capture devices will support all of the
-     above settings.
-
-     See the -pipeinput VID option below for a way to control the
-     settings through the VNC Viewer via keystrokes.
-
-     As above, if you specify a "@WxHxB..." after the <settings> string
-     they are used verbatim: the device is not queried for the current
-     values. Otherwise the device will be queried.
-
-   Also, if you supply the "-pipeinput VID" (or use "-rawfb Video")
-   option you can control the settings to some degree via keystroke
-   mappings, e.g. B to increase the brightness or Up arrow to change the
-   TV station:
-
-     For "-pipeinput VID" and you are using the -rawfb for a video
-     capture device, then an internal list of keyboard mappings is used
-     to set parameters of the video. The mappings are:
-
-         "B" and "b" adjust the brightness up and down.
-         "H" and "h" adjust the hue.
-         "C" and "c" adjust the colour.
-         "N" and "n" adjust the contrast.
-         "S" and "s" adjust the size of the capture screen.
-         "I" and "i" cycle through input channels.
-         Up and Down arrows adjust the station (if a tuner)
-         F1, F2, ..., F6 will switch the video capture pixel
-         format to HI240, RGB565, RGB24, RGB32, RGB555, and
-         GREY respectively. See -rawfb video for details.
-
-   See also the -freqtab option to supply your own xawtv channel to
-   frequency mappings for your country (only ntsc-cable-us is built into
-   x11vnc.)
-
-
-   Q-115: Can I connect via VNC to a Qt-embedded/Qt-enhanced/Qtopia
-   application running on my handheld, cell phone, or PC using the Linux
-   console framebuffer (i.e. not X11)?
-
-   Yes, the basic method for this is the -rawfb scheme where the Linux
-   console framebuffer (usually /dev/fb0) is polled and the uinput driver
-   is used to inject keystrokes and mouse input. Often you will just have
-   to type:
-  x11vnc -rawfb console
-
-   (you may need to enable the uinput driver on the system via "modprobe
-   uinput; mknod /dev/input/uinput c 10 223") If this does not find the
-   correct frame buffer properties figure them out or guess them and use
-   something like:
-  x11vnc -rawfb /dev/fb0@640x480x16
-
-   Also, to force usage of the uinput injection method use "-pipeinput
-   UINPUT". See the -pipeinput description for tunable parameters, etc.
-
-   One problem with the x11vnc uinput scheme is that it cannot guess the
-   mouse motion "acceleration" used by the windowing application (e.g.
-   QWS or X11.) For X11 and Qt-embedded the acceleration is usually 2
-   (i.e. a dx of 1 from the mouse yields a 2 pixel displacement of the
-   mouse cursor.) The default x11vnc uses is 2, since that is often used.
-   However for one Qt-embedded system we needed to do:
-  x11vnc -rawfb console  -pipeinput UINPUT:accel=4.0
-
-   to get reasonable positioning of the mouse.
-
-   Even with the correct acceleration setting there is still some drift
-   (probably because of the mouse threshold where the acceleration kicks
-   in) and so x11vnc needs to reposition the cursor from 0,0 about 5
-   times a second. See the -pipeinput UINPUT option for tuning parameters
-   that can be set (there are some experimental thresh=N tuning
-   parameters as well)
-
-   Currently, one can expect mouse input to be a little flakey. All in
-   all, the Linux framebuffer input mechanism for Qt-embedded framebuffer
-   apps is not perfect, but it is usable.
-
-   If you need to create a smaller x11vnc binary for a handheld
-   environment be sure to run strip(1) on it and also consider
-   configuring with, e.g. "env CPPFLAGS='-DSMALL_FOOTPRINT=1' ./configure
-   ..." to remove rarely used features and large texts (use 2 or 3
-   instead of 1 to remove more.) Currently (Jul/2006) this can lower the
-   size of the x11vnc from 1.1MB to 0.6-0.7MB.
-
-   The x11vnc uinput method applies to nearly anything on the Linux
-   framebuffer console, not just Qt-embedded/Qtopia. DirectFB, SDL using
-   fbcon driver, SVGAlib applications can also be viewed and interacted
-   with. Even a Linux X session can be viewed and interacted with without
-   using X11 (and x11vnc does not have to terminate when the X server
-   restarts!) The Linux Text consoles (F1-F6) also work.
-
-   Note that Qt-embedded supplies its own VNC graphics driver, but it
-   cannot do both the Linux console framebuffer and VNC at the same time,
-   which is often what is desired from VNC.
-
-   Update: We are finding some setups like Qtopia on the IPAQ do not
-   allow mouse input via uinput. Please help us debug this problem by
-   trying x11vnc on your device and letting us know what does and does
-   not work. See the next FAQ for a possible workaround for touchscreens.
-
-
-   Q-116: How do I inject touch screen input into an
-   Qt-embedded/Qt-enhanced/Qtopia cell phone such as openmoko/qtmoko Neo
-   Freerunner?
-
-   The qtmoko project does not use X11 for the graphical display.
-   Unfortunately the Linux uinput method described in the previous FAQ
-   does not work because Qt is using TSLIB (touch screen library) to
-   process the input and it only reads from one device (often
-   /dev/input/event1) and not from the new UINPUT device that x11vnc
-   creates (under -pipeinput UINPUT)
-
-   So something else needs to be done. It was discovered that by simply
-   writing the touchscreen events directly to /dev/input/event1 then
-   input can be injected into the system. There is no x11vnc builtin mode
-   for this yet (until we understand it better), but there is a working
-   script provided in x11vnc/misc/qt_tslib_inject.pl. So one could use it
-   this way for example:
-  x11vnc ... -rawfb console -pipeinput path/to/qt_tslib_inject.pl -env INJECT_O
-PTIONS=clickonly,cal=/etc/pointercal
-
-   Read the script for how to enable other options and what the above
-   options mean (e.g. /etc/pointercal contains TSLIB's calibration
-   parameters and are necessary to achieve accurate pointing.)
-
-   The x11vnc/misc/qt_tslib_inject.pl script can potentially be modified
-   to handle other devices where the uinput method fails. It could also
-   be modified to create 'hot keys', etc.
-
-   Please let us know how things go if you try this out; there is much to
-   learn about synthetic input injection in handhelds and cell phones. As
-   we learn more we can develop a builtin x11vnc mode for this sort of
-   injection.
-
-   Update Dec/2010: There is experimental built-in UINPUT support in the
-   x11vnc development tarball for qtmoko with touchpad managed by tslib.
-   See -pipeinput UINPUT for more info. Here is an example:
-   x11vnc -rawfb console -pipeinput UINPUT:touch,tslib_cal=/etc/pointercal,dire
-ct_abs=/dev/input/event1,nouinput,dragskip=3
-
-
-   Q-117: Now that non-X11 devices can be exported via VNC using x11vnc,
-   can I build it with no dependencies on X11 header files and libraries?
-
-   Yes, as of Jul/2006 x11vnc enables building for -rawfb only support.
-   Just do something like when building:
-  ./configure --without-x    (plus any other flags)
-  make
-
-   You can then test via "ldd x11vnc" that the binary does not depend on
-   libX11.so, etc. See the previous FAQ's for non-X11 framebuffer usage.
-   If you use this for an interesting non-X11 application please let us
-   know what you did.
-
-
-   Q-118: How do I cross compile x11vnc for a different architecture than
-   my Linux i386 or amd64 PC?
-
-   You will need a cross-compiling toolchain. Perhaps your distro
-   provides these or you can find a HOWTO for your distro. We found a
-   nice one at qtmoko.org for building armel binaries on Debian Linux
-   i386 machines. It includes most of the libraries that x11vnc needs. We
-   use that example here.
-
-   We ran this script to set PATH, configure, and build:
-#!/bin/sh
-
-# toolchain from: qtmoko-debian-toolchain-armv4t-eabi.tar.gz
-
-export PATH=/opt/toolchains/arm920t-eabi/bin:$PATH
-
-env CC=arm-linux-gcc ./configure --host=arm-linux --without-avahi
-
-make
-
-arm-linux-strip ./x11vnc/x11vnc
-ls -l ./x11vnc/x11vnc
-
-   Note we had to include --without-avahi due to lack of
-   libavahi-client.so.3 supplied by the toolchain we used. One would need
-   to add it if it was desired on the target machine. We also stripped
-   the binary to make it smaller.
-
-   For an embedded system one may also want to add --without-x if the
-   embedded system does not use X11 and the -rawfb mechanism must be
-   used.
-
-
-   Q-119: Does x11vnc support Mac OS X Aqua/Quartz displays natively
-   (i.e. no X11 involved)?
-
-   Yes, since Nov/2006 in the development tree (x11vnc-0.8.4 tarball)
-   there is support for native Mac OS X Aqua/Quartz displays using the
-   -rawfb mechanism described above. The mouse and keyboard input is
-   achieved via Mac OS X API's.
-
-   So you can use x11vnc as an alternative to OSXvnc (aka Vine Server),
-   or Apple Remote Desktop (ARD). Perhaps there is some x11vnc feature
-   you'd like to use on Mac OS X, etc. For a number of activities (e.g.
-   window drags) it seems to be faster than OSXvnc.
-
-   Notes:
-
-   X11:  x11vnc will also work (as it has for years) with a X11 server
-   (XDarwin) running on Mac OS X (people often install this software to
-   display remote X11 apps on their Mac OS X system, or use some old
-   favorites locally such as xterm.) However in this case x11vnc will
-   only work reasonably in single window -id windowid mode (and the
-   window may need to have mouse focus.)
-
-   If you do not have the DISPLAY env. variable set, x11vnc will assume
-   native Aqua/Quartz on Mac OS X, however if DISPLAY is set it will
-   assume an X11 connection. Use "-rawfb console" to force the native
-   display (or unset DISPLAY.)
-
-   Update: Leopard sets DISPLAY by default in all sessions. Since it
-   starts with the string "/tmp/" x11vnc will use that to know if it
-   should ignore it. Use "-display :0.0" to force it.
-
-   Building:  If you don't have the X11 build and runtime packages
-   installed you will need to build it like this:
-   (cd to the e.g. x11vnc-0.9, source directory)
-   ./configure --without-x
-   make
-
-   Win2VNC/x2vnc:  One handy use is to use the -nofb mode to redirect
-   mouse and keyboard input to a nearby Mac (i.e. one to the side of your
-   desk) via x2vnc or Win2VNC. See this FAQ for more info.
-
-   Options:  Here are the Mac OS X specific x11vnc options:
-   -macnodim              For the native Mac OS X server, disable dimming.
-   -macnosleep            For the native Mac OS X server, disable display sleep
-.
-   -macnosaver            For the native Mac OS X server, disable screensaver.
-   -macnowait             For the native Mac OS X server, do not wait for the
-                          user to switch back to his display.
-   -macwheel n            For the native Mac OS X server, set the mouse wheel
-                          speed to n (default 5.)
-   -macnoswap             For the native Mac OS X server, do not swap mouse
-                          buttons 2 and 3.
-   -macnoresize           For the native Mac OS X server, do not resize or rese
-t
-                          the framebuffer even if it is detected that the scree
-n
-                          resolution or depth has changed.
-   -maciconanim n         For the native Mac OS X server, set n to the number
-                          of milliseconds that the window iconify/deiconify
-                          animation takes.  In -ncache mode this value will be
-                          used to skip the animation if possible. (default 400)
-   -macmenu               For the native Mac OS X server, in -ncache client-sid
-e
-                          caching mode, try to cache pull down menus (not perfe
-ct
-                          because they have animated fades, etc.)
-
-   PasteBoard/Clipboard:   There is a bug that the Clipboard (called
-   PasteBoard on Mac it appears) exchange will not take place unless
-   x11vnc was started from inside the Aqua display (e.g. started inside a
-   Terminal app window.) Otherwise it cannot connect to the PasteBoard
-   server. So Clipboard exchange won't work for our standard "ssh in"
-   startup scheme.
-
-   Hopefully this deficiency can be removed, but until then for Clipboard
-   exchange to work you will need to start x11vnc inside the desktop
-   session (i.e. either start it running before you leave, or start up a
-   2nd x11vnc inside from a 1st one started outside, or use the apple
-   script below)
-
-   Here also is a osascript trick that seems to work (it opens the
-   Terminal app and instructs it to start x11vnc):
-
-#!/bin/sh
-#
-# start_x11vnc: start x11vnc in a Terminal window
-# (this will allow Clipboard/Pasteboard exchange to work)
-
-tmp=/tmp/start_x11vnc.$$
-
-cat > $tmp <<END
-
-tell application "Terminal"
-        activate
-        do script with command "$HOME/x11vnc -rfbauth .vnc/passwd -ssl SAVE"
-end tell
-
-END
-
-osascript $tmp
-rm -f $tmp
-
-   where you should customize the x11vnc command line to your needs and
-   the full path to the binary. Save it in a file e.g. "start_x11vnc" and
-   then after you SSH in just type "./start_x11vnc" (or have ssh run the
-   command for you.) Then once you are connected via VNC, iconify the
-   Terminal windows (you can't delete them since that will kill x11vnc.)
-
-   Update Aug/2010: A user reports the following useful information:
-This is not a problem on Mac OS X 10.6.x (Snow Leopard) when connecting
-via ssh to start x11vnc.  And, on Mac OS X 10.5.x (Leopard), the problem
-can be permanently eliminated by doing this:
-
-
-sudo /usr/libexec/PlistBuddy -c 'delete :LimitLoadToSessionType' \
-   -c 'add :LimitLoadToSessionType string Background' \
-   /System/Library/LaunchAgents/com.apple.pboard.plist
-# ignore any 'Delete: Entry, ":LimitLoadToSessionType", Does Not Exist' message
-
-and then restarting (yes, you must restart not just log off).  But
-ONLY do that for Mac OS X 10.5.x and NOT for 10.6.x (which doesn't
-need it anyway).
-
-   We recently got access to a MacOSX 10.6.4 (Snow Leopard) macbook and
-   have confirmed that the above is correct.
-
-
-   Q-120: Can x11vnc be used as a VNC reflector/repeater to improve
-   performance for the case of a large number of simultaneous VNC viewers
-   (e.g. classroom broadcasting or a large demo)?
-
-   Yes, as of Feb/2007 there is the "-reflect host:N" option to connect
-   to the VNC server "host:N" (either another x11vnc or any other VNC
-   server) and re-export it. VNC viewers then connect to the x11vnc(s)
-   running -reflect.
-
-   The -reflect option is the same as: "-rawfb vnc:host:N". See the
-   -rawfb description under "VNC HOST" for more details.
-
-   You can replace "host:N" with "listen" or "listen:port" for reverse
-   connections.
-
-   One can set up a number of such reflectors/repeaters to spread the
-   resource usage around, e.g.:
-       C -------<-------|
-       C -------<-------|
-       C -------<-------|---- R -----|
-       C -------<-------|            |
-       C -------<-------|            |
-                                     |
-       C -------<-------|            |
-       C -------<-------|            |
-       C -------<-------|---- R -----|
-       C -------<-------|            |
-       C -------<-------|            |
-                                     |====== S
-       C -------<-------|            |
-       C -------<-------|            |
-       C -------<-------|---- R -----|
-       C -------<-------|            |
-       C -------<-------|            |
-                                     |
-       C -------<-------|            |
-       C -------<-------|            |
-       C -------<-------|---- R -----|
-       C -------<-------|
-       C -------<-------|
-
-   Where "S" is the original VNC Server, "C" denote VNC viewer clients,
-   and "R" denotes an x11vnc running -reflect to "S".
-
-   Ideally, a client "C" will be fairly close network-wise to its "R". It
-   is fine to run the "R" on the same machine as one of its "C's". A nice
-   setup for a large, (e.g. 64-128) viewer classroom broadcast case would
-   be to run R's on areas isolated by network switches, e.g. one R per
-   switch.
-
-   In an extreme case (e.g. 1000 viewers) one might actually need a 2nd
-   layer of R's in the tree. If you try something like that let us know!
-
-   There are many resource savings in doing something like the above. The
-   first obvious one is network bandwidth savings. Another is less CPU
-   load on "S" since it handles many fewer simultaneous connections.
-   Also, if there are a few clients C on very slow links, their presence
-   does not slow down every other client, just the clients on their "R".
-   One way a slow client affects things is if there are some large
-   framebuffer writes (e.g. jpeg image region) then the repeater may
-   block waiting for that large write to finish before going onto the
-   next client (however, if the write is small enough, the kernel will
-   buffer it and the server can go on to service the next client.)
-
-   The x11vnc -reflect implementation uses the libvncclient library in
-   the LibVNCServer project to handle the connection to "S". It is not
-   currently very efficient since it simply does its normal framebuffer
-   polling scheme on the libvncclient framebuffer (which it then
-   re-exports via VNC to its clients C.) However, CopyRect and
-   CursorShape encodings are preserved in the reflection and that helps.
-   Dragging windows with the mouse can be a problem (especially if S is
-   not doing wireframing somehow, consider -nodragging if the problem is
-   severe) For a really fast reflector/repeater it would have to be
-   implemented from scratch with performance in mind. See these other
-   projects:
-    http://sourceforge.net/projects/vnc-reflector/,
-    http://www.tightvnc.com/projector/                (closed source?),
-
-
-   Automation via Reverse Connections:   Instead of having the R's
-   connect directly to S and then the C's connect directly to the R they
-   should use, some convenience can be achieved by using reverse
-   connections (the x11vnc ""-connect host1,host2,..." option.) Suppose
-   all the clients "C" are started up in Listen mode:
-    client1>  vncviewer -listen
-    client2>  vncviewer -listen
-    client3>  vncviewer -listen
-    ...
-    client64> vncviewer -listen
-
-   (e.g. client1> is the cmdline prompt on machine client1 ... etc) and
-   all the repeaters R are started like this:
-    repeater1> x11vnc -reflect listen -connect client1,client2,...client8
-    repeater2> x11vnc -reflect listen -connect client9,client10,...client16
-    ...
-    repeater8> x11vnc -reflect listen -connect client57,client58,...client64
-
-   and finally the main server is started to kick the whole thing into
-   motion:
-    vncserver> x11vnc -display :0 -connect repeater1,repeater2,...repeater8
-
-   (or instruct a non-x11vnc VNC server to reverse connect to the
-   repeaters.) For a classroom broadcasting setup one might have the
-   first two sets of commands start automatically at bootup or when
-   someone logs in, and then start everything up with the S server. One
-   may even be able to script the forward connection bootstrap case, let
-   us know what you did. A really nice thing would be some sort of
-   auto-discovery of your repeater, etc...
-
-   Q-121: Can x11vnc be used during a Linux, Solaris, etc. system
-   Installation so the Installation can be done remotely?
-
-   This can be done, but it doesn't always work because it depends on how
-   the OS does its install. We have to "sneak in" somehow. Note that some
-   OS's have a remote install (ssh etc.) built in and so you might want
-   to use that instead.
-
-   Usually the OS install will have to be a network-install in order to
-   have networking up during the install. Otherwise, you may have a
-   (slim) chance to configure the networking manually (ifconfig(8) and
-   route(8).)
-
-   To avoid library dependencies problems in the typical minimal (e.g.
-   busybox) installation OS it is a good idea to build a statically
-   linked x11vnc binary. A way that often works is to do a normal build
-   and then paste the final x11vnc link line into a shell script. Then
-   change the "gcc" to "gcc -static" and run the shell script. You may
-   need to disable features (e.g. "--without-xfixes") if there is not a
-   static library for the feature available. You may also need to add
-   extra link options (e.g. "-lXrender") to complete library dependencies
-   manually.
-
-   Let's call the binary x11vnc.static. Place it on a webserver
-   somewhere. It may be possible to retrieve it via scp(1) too.
-
-   During the install you need to get a shell to retreive x11vnc.static
-   and run it.
-
-   If the Solaris install is an older X-based one, there will be a menu
-   for you to get a terminal window. From that window you might be able
-   to retrieve x11vnc.static via wget, scp, or ftp. Remember to do "chmod
-   755 ./x11vnc.static" and then find the -auth file as in this FAQ.
-
-   If it is a Linux install that uses an X server (e.g. SuSE and probably
-   Fedora), then you can often get a shell by pressing Ctrl-Alt-F2 or
-   similar. Then get the x11vnc binary via something like this:
-   cd /tmp
-   wget http://192.168.0.22/x11vnc.static
-   chmod 755 ./x11vnc.static
-
-   Find the name of the auth file as in this FAQ. (maybe run "ps wwaux |
-   grep auth".) Then run it like this:
-   ./x11vnc.static -forever -nopw -display :0 -auth /tmp/wherever/the/authfile
-
-   then press Alt-F7 to go back to the X install. You should now be able
-   to connect via a vnc viewer and continue the install. Watch out for
-   the display being :1, etc.
-
-   If there is a firewall blocking incoming connections during the
-   install, use the "-connect hostname" option option for a reverse
-   connection to the hostname running the VNC viewer in listen mode.
-
-   Debian based installs are either console-text or console-framebuffer
-   based. These are install (or expert) and installgui (or expertgui)
-   boot lines, respectively. For the console-text based installs you
-   probably need to add a boot cmd line option like vga=0x314 (which is
-   800x600x16) to get the console-text to use the linux framebuffer
-   device properly.
-
-   For a Debian console-text based install after the network is
-   configured press Ctrl-Alt-F2 to get a shell. Retrieve the binary via
-   wget as above and chmod 755 it. Then run it something like this:
-   sleep 10; ./x11vnc.static -forever -nopw -rawfb console
-
-   then before the sleep is over press Alt-F1 to get back to the install
-   virtual console. You should be able to connect via a VNC viewer and
-   continue with the install.
-
-   For a recent (2009) Debian install we booted with "expert vga=0x301"
-   and "expert vga=0x311" to get console text based installs at 640x480x8
-   and 640x480x16, respectively (replace "expert" with "install" if you
-   like.) Otherwise it was giving a 16 color 640x480x4 (4 bit per pixel)
-   display which x11vnc could not handle.
-
-   For Debian console-framebuffer GUI based installs (installgui or
-   expertgui) we have not be able to enter keystrokes or mouse motions.
-   This may be resolved if the install had the Linux kernel module
-   uinput, but it doesn't; one can wget uinput.ko and then run insmod on
-   it, but the module must match the installation kernel. So, failing
-   that, you can only do the GUI view-only, which can be handy to watch a
-   long network install from your desk instead of in front of the machine
-   being installed. For these, after the network is configured press
-   Ctrl-Alt-F2 to get a shell. Retrieve the binary via wget as above and
-   chmod 755 it. Then run it something like this:
-   sleep 10; ./x11vnc.static -forever -nopw -rawfb console
-
-   then before the sleep is over press Alt-F5 to get back to the GUI
-   install console. You should be able to connect via a VNC viewer and
-   watch the install.
-   [Misc: Clipboard, File Transfer/Sharing, Printing, Sound, Beeps,
-   Thanks, etc.]
-
-   Q-122: Does the Clipboard/Selection get transferred between the
-   vncviewer and the X display?
-
-   As of Jan/2004 x11vnc supports the "CutText" part of the RFB (aka VNC)
-   protocol. When text is selected/copied in the X session that x11vnc is
-   polling it will be sent to connected VNC viewers. And when CutText is
-   received from a VNC viewer then x11vnc will set the X11 selections
-   PRIMARY, CLIPBOARD, and CUTBUFFER0 to it. x11vnc is able to hold the
-   PRIMARY and CLIPBOARD selections (Xvnc does not seem to do this.)
-
-   The X11 selections can be confusing, especially to those coming from
-   Windows or MacOSX where there is just a single 'Clipboard'. The X11
-   CLIPBOARD selection is a lot like that of Windows and MacOSX, e.g.
-   highlighted text is sent to the clipboard when the user activates
-   "Edit -> Copy" or presses "Control+C" (and pasting it via "Edit ->
-   Paste" or "Control+V".) The X11 PRIMARY selection has been described
-   as 'for power users' or 'an Easter Egg'. As soon as text is
-   highlighted it is set to the PRIMARY selection and so it is
-   immediately ready for pasting, usually via the Middle Mouse Button or
-   "Shift+Insert". See this jwz link for more information.
-
-   x11vnc's default behavior is to watch both CLIPBOARD and PRIMARY and
-   whenever one of them changes, it sends the new text to connected
-   viewers. Note that since the RFB protocol only has a single "CutText"
-   then both selections are "merged" to some degree (and this can lead to
-   confusing results.) One user was confused why x11vnc was "forgetting"
-   his CLIPBOARD selection and the reason was he also changed PRIMARY
-   some time after he copied text to the clipboard. Usually an app will
-   set PRIMARY as soon as any text is highlighted so it easy to see how
-   CLIPBOARD was forgotten. Use the -noprimary described below as a
-   workaround. Similarly, by default when x11vnc receives CutText it sets
-   both CLIPBOARD and PRIMARY to it (this is probably less confusing, but
-   could possibly lead to some failure modes as well.)
-
-   You may not like these defaults. Here are ways to change the behavior:
-     * If you don't want the Clipboard/Selection exchanged at all use the
-       -nosel option.
-     * If you want changes in PRIMARY to be ignored use the -noprimary
-       option.
-     * If you want changes in CLIPBOARD to be ignored use the
-       -noclipboard option.
-     * If you don't want x11vnc to set PRIMARY to the "CutText" received
-       from viewers use the -nosetprimary option.
-     * If you don't want x11vnc to set CLIPBOARD to the "CutText"
-       received from viewers use the -nosetclipboard option.
-
-   You can also fine-tune it a bit with the -seldir dir option and also
-   -input.
-
-   You may need to watch out for desktop utilities such as KDE's
-   "Klipper" that do odd things with the selection, clipboard, and
-   cutbuffers.
-
-
-   Q-123: Can I use x11vnc to record a Shock Wave Flash (or other format)
-   video of my desktop, e.g. to record a tutorial or demo?
-
-   Yes, it is possible with a number of tools that record VNC and
-   transform it to swf format or others. One such popular tool is
-   pyvnc2swf. There are a number of tutorials (broken link?) on how to do
-   this. Another option is to use the vnc2mpg that comes in the
-   LibVNCServer package.
-   An important thing to remember when doing this is that tuning
-   parameters should be applied to x11vnc to speed up its polling for
-   this sort of application, e.g. "-wait 10 -defer 10".
-
-   Q-124: Can I transfer files back and forth with x11vnc?
-
-   As of Oct/2005 and May/2006 x11vnc enables, respectively, the TightVNC
-   and UltraVNC file transfer implementations that were added to
-   libvncserver. This currently works with TightVNC and UltraVNC viewers
-   (and Windows viewers only support filetransfer it appears... but they
-   do work to some degree under Wine on Linux.)
-
-   The SSVNC Unix VNC viewer supports UltraVNC file transfer by use of a
-   Java helper program.
-
-   TightVNC file transfer is off by default, if you want to enable it use
-   the -tightfilexfer option.
-
-   UltraVNC file transfer is off by default, to enable it use something
-   like "-rfbversion 3.6 -permitfiletransfer"
-   options (UltraVNC incorrectly uses the RFB protocol version to
-   determine if its features are available, so x11vnc has to pretend to
-   be version 3.6.) As of Sep/2006 "-ultrafilexfer" is an alias for these
-   two options. Note that running as RFB version 3.6 may confuse other
-   VNC Viewers.
-
-   Sadly you cannot do both -tightfilexfer and -ultrafilexfer at the same
-   time because the latter requires setting the version to 3.6 and
-   tightvnc will not do filetransfer when it sees that version number.
-
-   Also, because of the way the LibVNCServer TightVNC file transfer is
-   implemented, you cannot do Tightvnc file transfer in -unixpw mode.
-   However, UltraVNC file transfer does work in -unixpw (but if a client
-   tries it do a filetransfer during the login process it will be
-   disconnected.)
-
-   IMPORTANT: please understand if -ultrafilexfer or -tightfilexfer is
-   specified and you run x11vnc as root for, say, inetd or display
-   manager (gdm, kdm, ...) access and you do not have it switch users via
-   the -users option, then VNC Viewers that connect are able to do
-   filetransfer reads and writes as *root*.
-
-   The UltraVNC and TightVNC settings can be toggled on and off inside
-   the gui or by -R remote control. However for TightVNC the changed
-   setting only applies for NEW clients, current clients retain their
-   TightVNC file transfer ability. For UltraVNC it works better, however
-   if an UltraVNC client has initiated a file transfer dialog it will
-   remain in effect until the dialog is closed. If you want to switch
-   between UltraVNC and TightVNC file transfer in the gui or by remote
-   control you will probably be foiled by the "-rfbversion 3.6" issue.
-
-
-   Q-125: Which UltraVNC extensions are supported?
-
-   Some of them are supported. To get UltraVNC Viewers to attempt to use
-   these extensions you will need to supply this option to x11vnc:
-   -rfbversion 3.6
-
-   Or use -ultrafilexfer which is an alias for the above option and
-   "-permitfiletransfer". UltraVNC evidently treats any other RFB version
-   number as non-UltraVNC.
-
-   Here are a list of the UltraVNC extensions supported by x11vnc:
-     * ServerInput: "Toggle Remote Input and Remote Blank Monitor"
-     * FileTransfer: "Open File Transfer..."
-     * SingleWindow: "Select Single Window..."
-     * TextChat: "Open Chat..."
-     * 1/n Server Scaling
-
-   The SSVNC Unix VNC viewer supports these UltraVNC extensions.
-
-   To disable SingleWindow and ServerInput use -noultraext (the others
-   are managed by LibVNCServer.) See this option too: -noserverdpms.
-
-   Also, the UltraVNC repeater proxy is supported for use with reverse
-   connections: "-connect repeater://host:port+ID:NNNN". Use it for both
-   plaintext and SSL connections. This mode can send any string before
-   switching to the VNC protocol, and so could be used with other
-   proxy/gateway tools. Also, a perl repeater implemention is here:
-   ultravnc_repeater.pl
-
-
-   Q-126: Can x11vnc emulate UltraVNC's Single Click helpdesk mode for
-   Unix? I.e. something very simple for a naive user to initiate a
-   reverse vnc connection from their Unix desktop to a helpdesk
-   operator's VNC Viewer.
-
-   Yes, UltraVNC's Single Click (SC) mode can be emulated fairly well on
-   Unix.
-
-   We use the term "helpdesk" below, but it could be any sort of remote
-   assistance you want to set up, e.g. something for Unix-using friends
-   or family to use. This includes Mac OS X.
-
-   Assume you create a helpdesk directory "hd" on your website:
-   http://www.mysite.com/hd (any website that you can upload files to
-   should work, although remember the user will be running the programs
-   you place there.)
-
-   In that "hd" subdirectory copy an x11vnc binary to be run on the Unix
-   user's machine (e.g. Linux, etc) and also create a file named "vnc"
-   containing the following:
-#!/bin/sh
-
-webhost="http://www.mysite.com/hd"  # Your helpdesk dir URL.
-
-vnchost="ip.someplace.net"          # Your host running 'vncviewer -listen'
-                                    # It could also be your IP number. If it is
-                                    # a router/firewall, you will need to
-                                    # configure it to redirect port 5500 to you
-r
-                                    # workstation running 'vncviewer -listen'
-
-dir=/tmp/vnc_helpdesk.$$            # Make a temporary working dir.
-mkdir $dir || exit 1
-cd $dir || exit 1
-
-trap "cd /tmp; rm -rf $dir" 0 2 15  # Cleans up on exit.
-
-wget $webhost/x11vnc                # Fetch x11vnc binary.  If multi-
-chmod 755 ./x11vnc                  # platform, use $webhost/`uname`/x11vnc
-                                    # or similar.
-
-./x11vnc -connect_or_exit $vnchost -rfbport 0 -nopw
-
-   with the hostnames / IP addresses customized to your case.
-
-   On the helpdesk VNC viewer machine (ip.someplace.net in this example)
-   you have the helpdesk operator running VNC viewer in listen mode:
-   vncviewer -listen
-
-   or if on Windows, etc. somehow have the VNC viewer be in "listen"
-   mode.
-
-   Then, when the naive user needs assistance you instruct him to open up
-   a terminal window on his Unix desktop and paste the following into the
-   shell:
-   wget -qO - http://www.mysite.com/hd/vnc | sh -
-
-   and then press Enter. You could have this instruction on a web page or
-   in an email you send him, etc. This requires that the wget is
-   installed on the user's Unix machine (he might only have curl or lynx,
-   see below for more info.)
-
-
-   So I guess this is about 3-4 clicks (start a terminal and paste) and
-   pressing "Enter" instead of "single click"...
-
-   See this page for some variations on this method, e.g. how to add a
-   password, SSL Certificates, etc.
-
-
-   If you don't have a website (there are many free ones) or don't want
-   to use one you will have to email him all of the ingredients (x11vnc
-   binary and a launcher script) and tell him how to run it. This could
-   be easy or challenging depending on the skill of the naive unix
-   user...
-
-   A bit of obscurity security could be put in with a -passwd, -rfbauth
-   options, etc. (note that x11vnc will require a password even for
-   reverse connections.) More info here.
-
-
-   Firewalls: If the helpdesk (you) with the vncviewer is behind a
-   NAT/Firewall/Router the router will have to be configured to redirect
-   a port (i.e. 5500 or maybe different one if you like) to the vncviewer
-   machine. If the vncviewer machine also has its own host-level
-   firewall, you will have to open up the port there as well.
-
-   NAT-2-NAT: There is currently no way to go "NAT-2-NAT", i.e. both User
-   and Helpdesk workstations behind NAT'ing Firewall/Routers without
-   configuring a router to do a port redirection (i.e. on your side, the
-   HelpDesk.) To avoid modifying either firewall/router, one would need
-   some public (IP address reachable on the internet) redirection/proxy
-   service. Perhaps such a thing exists. http://sc.uvnc.com provides this
-   service for their UltraVNC Single Click users.
-
-   Update: It may be possible to do "NAT-2-NAT" with a UDP tunnel such as
-   http://samy.pl/pwnat/. All that is required is that both NAT firewalls
-   allow in UDP packets from an IP address to which a UDP packet has
-   recently been sent to. If you try it out let us know how it went.
-
-
-   Very Naive Users:
-
-   If it is beyond the user how to open a terminal window and paste in a
-   command (you have my condolences...) you would have to somehow setup
-   his Web browser to download the "vnc" file (or a script containing the
-   above wget line) and prompt the user if he wants to run it. This may
-   be tricky to set up (which is probably a good thing to not have the
-   web browser readily run arbitrary programs downloaded from the
-   internet...)
-
-   One command-line free way, tested with KDE, is to name the file vnc.sh
-   and then instruct the user to right-click on the link and do "Save
-   Link As" to his Desktop. It will appear as an icon, probably one that
-   looks like a terminal or a command line prompt. He next should
-   right-click on the icon and select "Properties" and go to the
-   "Permissions" tab. Then in that dialog select the checkbox "Is
-   executable". He should then be able to click on the icon to launch it.
-   Another option is to right-click on the icon and select "Open With ->
-   Other ..." and for the name of the application type in "/bin/sh".
-   Unfortunately in both cases the command output is lost and so errors
-   cannot be debugged as easily. A similar thing appears to work in GNOME
-   if under "Properties -> Permissions" they click on "Execute" checkbox
-   for "Owner". Then when they click on the icon, they will get a dialog
-   where they can select "Run in Terminal". In general for such cases, if
-   it is feasible, it might be easier to ssh to his machine and set
-   things up yourself...
-
-
-   SSL Encrypted Helpdesk Connections:
-
-   As of Apr/2007 x11vnc supports reverse connections in SSL and so we
-   can do this. On the Helpdesk side (Viewer) you will need STUNNEL or
-   better use the Enhanced TightVNC Viewer (SSVNC) package we provide
-   that automates all of the SSL for you.
-
-   To do this create a file named "vncs" in the website "hd" directory
-   containing the following:
-#!/bin/sh
-
-webhost="http://www.mysite.com/hd"  # Your helpdesk dir URL.
-
-vnchost="ip.someplace.net"          # Your host running 'vncviewer -listen'
-                                    # It could also be your IP number. If it is
-                                    # a router/firewall, you will need to
-                                    # configure it to redirect port 5500 to you
-r
-                                    # workstation running 'vncviewer -listen'
-
-dir=/tmp/vnc_helpdesk.$$            # Make a temporary working dir.
-mkdir $dir || exit 1
-cd $dir || exit 1
-
-trap "cd /tmp; rm -rf $dir" 0 2 15  # Cleans up on exit.
-
-wget $webhost/x11vnc                # Fetch x11vnc binary.  If multi-
-chmod 755 ./x11vnc                  # platform, use $webhost/`uname`/x11vnc
-                                    # or similar.
-
-./x11vnc -connect_or_exit $vnchost -rfbport 0 -nopw -ssl    # Note -ssl option.
-
-   with the hostnames or IP addresses customized to your case.
-
-   The only change from the "vnc" above is the addition of the -ssl
-   option to x11vnc. This will create a temporary SSL cert: openssl(1)
-   will need to be installed on the user's end. A fixed SSL cert file
-   could be used to avoid this (and provide some authentication; more
-   info here.)
-
-   The naive user will be doing this:
-   wget -qO - http://www.mysite.com/hd/vncs | sh -
-
-   (or perhaps even use https:// if available.)
-
-   But before that, the helpdesk operator needs to have "vncviewer
-   -listen" running as before, however he needs an SSL tunnel at his end.
-   The easiest way to do this is use Enhanced TightVNC Viewer (SSVNC).
-   Start it, and select Options -> 'Reverse VNC Connection (-listen)'.
-   Then UN-select 'Verify All Certs' (this can be enabled later if you
-   want; you'll need the x11vnc SSL certificate), and click 'Listen'.
-
-   If you don't want to use SSVNC for the viewer, but rather set up
-   STUNNEL manually instead, make a file "stunnel.cfg" containing:
-foreground = yes
-pid =
-
-[vnc]
-accept = 5500
-connect = localhost:5501
-
-   and run:
-  stunnel ./stunnel.cfg
-
-   and then start the "vncviewer -listen 1" (i.e. 1 to correspond to the
-   5501 port.) Note that this assumes the stunnel install created a
-   Server SSL cert+key, usually /etc/stunnel/stunnel.pem (not all distros
-   will do this.) Also, that file is by default only readable by root, so
-   stunnel needs to be run as root. If your system does not have a key
-   installed or you do not want to run stunnel as root (or change the
-   permissions on the file), you can use x11vnc to create one for you for
-   example:
-  x11vnc -sslGenCert server self:mystunnel
-
-   answer the prompts with whatever you want; you can take the default
-   for all of them if you like. The openssl(1) package must be installed.
-   See this link and this one too for more info on SSL certs. This
-   creates $HOME/.vnc/certs/server-self:mystunnel.pem, then you would
-   change the "stunnel.cfg" to look something like:
-foreground = yes
-pid =
-cert = /home/myusername/.vnc/certs/server-self:mystunnel.pem
-
-[vnc]
-accept = 5500
-connect = localhost:5501
-
-   In any event, with stunnel having been setup, the naive user is
-   instructed to paste in and run:
-   wget -qO - http://www.mysite.com/hd/vncs | sh -
-
-   to pick up the vncs script this time.
-
-   Of course if a man-in-the-middle can alter what the user downloads
-   then all bets are off!.
-
-   More SSL variations and info about certificates can be found here.
-
-
-   OpenSSL libssl.so.0.9.7 problems:
-
-   If you build your own stunnel or x11vnc for deployment, you may want
-   to statically link libssl.a and libcrypto.a into it because Linux
-   distros are currently a bit of a mess regarding which version of
-   libssl is installed.
-
-   You will find the details here.
-
-
-   Q-127: Can I (temporarily) mount my local (viewer-side) Windows/Samba
-   File share on the machine where x11vnc is running?
-
-   You will have to use an external network redirection for this.
-   Filesystem mounting is not part of the VNC protocol.
-
-   We show a simple Samba example here.
-
-   First you will need a tunnel to redirect the SMB requests from the
-   remote machine to the one you sitting at. We use an ssh tunnel:
-  sitting-here> ssh -C -R 1139:localhost:139 far-away.east
-
-   Or one could combine this with the VNC tunnel at the same time, e.g.:
-  sitting-here> ssh -C -R 1139:localhost:139 -t -L 5900:localhost:5900 far-away
-.east 'x11vnc -localhost -display :0'
-
-   Port 139 is the Windows Service port. For Windows systems instead of
-   Samba, you may need to use the actual IP address of the Window machine
-   instead of "localhost" in the -R option (since the Windows service
-   does not listen on localhost by default.)
-
-   Note that we use 1139 instead of 139 on the remote side because 139
-   would require root permission to listen on (and you may have a samba
-   server running on it already.)
-
-   The ssh -C is to enable compression, which might speed up the data
-   transfers.
-
-   Depending on the remote system side configuration, it may or may not
-   be possible to mount the SMB share as a non-root user. Try it first as
-   a non-root user and if that fails you will have to become root.
-
-   We will assume the user name is "fred" and we will try to mount the
-   viewer-side Windows SMB share "//haystack/pub" in
-   /home/fred/smb-haystack-pub.
-  far-away> mkdir -p /home/fred/smb-haystack-pub
-  far-away> smbmount //haystack/pub /home/fred/smb-haystack-pub -o username=fre
-d,ip=127.0.0.1,port=1139
-
-   (The 2nd command may need to be run as root.) Then run "df" or "ls -l
-   /home/fred/smb-haystack-pub" to see if it is mounted properly. Consult
-   the smbmount(8) and related documentation (it may require some
-   fiddling to get write permissions correct, etc.) To unmount:
-  far-away> smbumount /home/fred/smb-haystack-pub
-
-   At some point we hope to fold some automation for SMB ssh redir setup
-   into the Enhanced TightVNC Viewer (SSVNC) package we provide (as of
-   Sep 2006 it is there for testing.)
-
-
-   Q-128: Can I redirect CUPS print jobs from the remote desktop where
-   x11vnc is running to a printer on my local (viewer-side) machine?
-
-   You will have to use an external network redirection for this.
-   Printing is not part of the VNC protocol.
-
-   We show a simple Unix to Unix CUPS example here. Non-CUPS port
-   redirections (e.g. LPD) should also be possible, but may be a bit more
-   tricky. If you are viewing on Windows SMB and don't have a local cups
-   server it may be trickier still (see below.)
-
-   First you will need a tunnel to redirect the print requests from the
-   remote machine to the one you sitting at. We use an ssh tunnel:
-  sitting-here> ssh -C -R 6631:localhost:631 far-away.east
-
-   Or one could combine this with the VNC tunnel at the same time, e.g.:
-  sitting-here> ssh -C -R 6631:localhost:631 -t -L 5900:localhost:5900 far-away
-.east 'x11vnc -localhost -display :0'
-
-   Port 631 is the default CUPS port. The above assumes you have a Cups
-   server running on your viewer machine (localhost:631), if not, use
-   something like my-cups-srv:631 (the viewer-side Cups server) in the -R
-   instead.
-
-   Note that we use 6631 instead of 631 on the remote side because 631
-   would require root permission to listen on (and you likely have a cups
-   server running on it already.)
-
-   Now the tricky part: to get applications to notice your cups
-   server/printer on localhost:6631.
-
-   If you have administrative privilege (i.e. root password) on the
-   x11vnc side where the desktop is running, it should be easy to add the
-   printer through some configuration utility (e.g. in KDE: Utilities ->
-   Printing -> Printing Manager, and then supply admin password, and then
-   Add Printer/Class, and then fill in the inquisitive wizard. Most
-   important is the "Remote IPP server" panel where you put in localhost
-   for Host and 6631 for Port.) The main setting you want to convey is
-   the host is localhost and the port is non-standard (e.g. 6631.) Some
-   configuration utilities will take an Internet Printing Protocol (IPP)
-   URI, e.g. http://localhost:6631/printers/,
-   ipp://localhost:6631/printers/printer-name,
-   ipp://localhost:6631/ipp/printer-name, etc. Check your CUPS
-   documentation and admin interfaces to find what the syntax is and what
-   the "printer name" is.
-
-   If you do not have root or print admin privileges, but are running a
-   recent (version 1.2 or greater) of the Cups client software, then an
-   easy way to temporarily switch Cups servers is to create the directory
-   and file: $HOME/.cups/client.conf on the remote side with a line like:
-  ServerName localhost:6631
-
-   When not using x11vnc for remote access you can comment the above line
-   out with a '#' (or rename the client.conf file), to have normal cups
-   operation.
-
-   Unfortunately, running applications may need to be restarted to notice
-   the new printers (libcups does not track changes in client.conf.)
-   Depending on circumstances, a running application may actually notice
-   the new printers without restarting (e.g. no print dialog has taken
-   place yet, or there are no CUPS printers configured on the remote
-   side.)
-
-   Cups client software that is older (1.1) does not support appending
-   the port number, and for newer ones there is a bug preventing it from
-   always working (fixed in 1.2.3.) Kludges like these at the command
-   line will work:
-  far-away> env CUPS_SERVER=localhost IPP_PORT=6631 lpstat -p -d
-  far-away> env CUPS_SERVER=localhost IPP_PORT=6631 lpr -P myprinter file.ps
-  far-away> env CUPS_SERVER=localhost IPP_PORT=6631 firefox
-
-   but are somewhat awkward since you have to retroactively set the env.
-   var IPP_PORT. Its value cannot be broadcast to already running apps
-   (like the $HOME/.cups/client.conf trick sometimes does.) A common
-   workaround for an already running app is to somehow get it to "Print
-   To File", e.g. file.ps and then use something like the lpr example
-   above. Also, the option "-h host:port" works with CUPS lp(1) and
-   lpr(1).
-
-   You can also print to Windows shares printers in principle. You may do
-   this with the smbspool(8) command, or configure the remote CUPS via
-   lpadmin(8), etc, to use a printer URI something like
-   smb://machine:port/printer (this may have some name resolution
-   problems WRT localhost.) Also, as with SMB mounting, the port redir
-   (-R) to the Windows machine must use the actual IP address instead of
-   "localhost".
-
-   At some point we hope to fold some automation for CUPS ssh redir setup
-   into the Enhanced TightVNC Viewer (SSVNC) package we provide (as of
-   Sep 2006 it is there for testing.)
-
-
-   Q-129: How can I hear the sound (audio) from the remote applications
-   on the desktop I am viewing via x11vnc?
-
-   You will have to use an external network audio mechanism for this.
-   Audio is not part of the VNC protocol.
-
-   We show a simple Unix to Unix esd example here (artsd should be
-   possible too, we have also verified the esd Windows port works for the
-   method described below.)
-
-   First you will need a tunnel to redirect the audio from the remote
-   machine to the one you sitting at. We use an ssh tunnel:
-  sitting-here> ssh -C -R 16001:localhost:16001 far-away.east
-
-   Or one could combine this with the VNC tunnel at the same time, e.g.:
-  sitting-here> ssh -C -R 16001:localhost:16001 -t -L 5900:localhost:5900 far-a
-way.east 'x11vnc -localhost -display :0'
-
-   Port 16001 is the default ESD uses. So when an application on the
-   remote desktop makes a sound it will connect to this tunnel and be
-   redirected to port 16001 on the local machine (sitting-here in this
-   example.) The -C option is an attempt to compress the audio a little
-   bit.
-
-   So we next need a local (sitting-here) esd daemon running that will
-   receive those requests and play them on the local sound device:
-  sitting-here> esd -promiscuous -port 16001 -tcp -bind 127.0.0.1
-
-   See the esd(1) man page for the meaning of the options (the above are
-   not very secure.) (This method also works with the EsounD windows port
-   esd.exe)
-
-   To test this sound tunnel, we use the esdplay program to play a simple
-   .wav file:
-  far-away> esdplay -s localhost:16001 im_so_happy.wav
-
-   If you hear the sound (Captain Kirk in this example), that means you
-   are in great shape.
-
-   To run individual audio applications you can use the esddsp(1)
-   command:
-  far-away> esddsp -s localhost:16001 xmms
-
-   Then you could try playing some sounds inside xmms. You could also set
-   the environment variable ESPEAKER=localhost:16001 to not need to
-   supply the -s option all the time. (for reasons not clear, sometimes
-   esddsp can figure it out on its own.) All the script esddsp does is to
-   set ESPEAKER and LD_PRELOAD for you so that when the application opens
-   the sound device (usually /dev/dsp) its interactions with the device
-   will be intercepted and sent to the esd daemon running on sitting-here
-   (that in turn writes them to the real, local /dev/dsp.)
-
-   Redirecting All sound:
-
-   It does not seem to be possible to switch all of the sound of the
-   remote machine from its sound device to the above esd+ssh tunnel
-   without some preparation. But it can be done reasonably well if you
-   prepare (i.e. restart) the desktop with this in mind.
-
-   Here is one way to redirect all sound. The idea is we run the entire
-   desktop with sound directed to localhost:16001. When we are sitting at
-   far-away.east we run "esd -promiscuous -port 16001 -tcp -bind
-   127.0.0.1" on far-away.east (to be able to hear the sound.) However,
-   when we are sitting at sitting-here.west we kill that esd process and
-   run that same esd command on sitting-here.west and start up the above
-   ssh tunnel. This is a little awkward, but with some scripts one would
-   probably kill and restart the esd processes automatically when x11vnc
-   is used.
-
-   So next we have to run the whole desktop pointing toward our esd. Here
-   is a simple way to test. Log in to the machine via the "FailSafe"
-   desktop. Then in the lone terminal type something like:
-  esddsp -s localhost:16001 gnome-session
-or:
-  esddsp -s localhost:16001 startkde
-
-   where the last part is whatever command starts your desktop (even
-   fvwm2.) This causes the environment variables ESPEAKER and LD_PRELOAD
-   to be set appropriately and every application (processes with the
-   desktop as an ancestor) will use them. If this scheme works well you
-   can make it less klunky by adding the command to your ~/.xsession,
-   etc. file that starts your default desktop. Or you may be able to
-   configure your desktop to use localhost:16001, or whatever is needed,
-   via a gui configuration panel. Some Notes:
-     * Not all audio applications are compatible with the esd and artsd
-       mechanisms, but many are.
-     * The audio is not compressed so you probably need a broadband or
-       faster connection. Listening to music may not be very pleasant...
-       (Although we found streaming music from across the US over cable
-       modem worked OK, but took 200 KB/sec, to use less bandwidth
-       consider something like "ssh far-away.east 'cat favorite.mp3' |
-       mpg123 -b 4000 -")
-     * Linux does not seem to have the concept of LD_PRELOAD_64 so if you
-       run on a mixed 64- and 32-bit ABI system (e.g. AMD x86_64) some of
-       the applications will fail to run because LD_PRELOAD will point to
-       libraries of the wrong wordsize.
-     * At some point we hope to fold some automation for esd or artsd ssh
-       redir setup into the Enhanced TightVNC Viewer (SSVNC) package we
-       provide (as of Sep/2006 it is there for testing.)
-
-
-   Q-130: Why don't I hear the "Beeps" in my X session (e.g. when typing
-   tput bel in an xterm)?
-
-   As of Dec/2003 "Beep" XBell events are tracked by default. The X
-   server must support the XKEYBOARD extension (this is not on by default
-   in Solaris, see Xserver(1) for how to turn it on via +kb), and so you
-   won't hear them if the extension is not present.
-
-   If you don't want to hear the beeps use the -nobell option. If you
-   want to hear the audio from the remote applications, consider trying a
-   redirector such as esd.
-
-
-   Q-131: Does x11vnc work with IPv6?
-
-   Update: as of Apr/2010 in the 0.9.10 x11vnc development tarball, there
-   is now built-in support for IPv6 (128 bit internet addresses.) See the
-   -6 and -connect options for details.
-
-   The remainder of this FAQ entry shows how to do with this with pre
-   0.9.10 x11vnc using IPv6 helper tools.
-     _________________________________________________________________
-
-   Using an external IPv6 helper:
-   A way to do this is via a separate helper program such as inetd (or
-   for encrypted connections: ssh or stunnel.) For example, you configure
-   x11vnc to be run from inetd or xinetd and instruct it to listen on an
-   IPv6 address. For xinetd the setting "flags = IPv6" will be needed.
-   For inetd.conf, an example is:
-  5900 stream tcp6 nowait root /usr/sbin/tcpd /usr/local/bin/x11vnc_wrapper.sh
-
-   We also provide a transitional tool in "x11vnc/misc/inet6to4" that
-   acts as a relay for any IPv4 application to allow connections over
-   IPv6. For example:
-  inet6to4 5900 localhost:5900
-
-   where x11vnc is listening on IPv4 port 5900.
-
-   Also note that not all VNC Viewers are IPv6 enabled, so a redirector
-   may also be needed for them. The tool "inet6to4 -r ..." can do this as
-   well. SSVNC (see below) supports IPv6 without need for the helper.
-
-  # ./inet6to4 -help
-
-  inet6to4:  Act as an ipv6-to-ipv4 relay for tcp applications that
-             do not support ipv6.
-
-  Usage:     inet6to4
-             inet6to4 -r
-
-  Examples:  inet6to4 5900 localhost:5900
-             inet6to4 8080 web1:80
-             inet6to4 -r 5900 fe80::217:f2ff:fee6:6f5a%eth0:5900
-
-  The -r option reverses the direction of translation (e.g. for ipv4
-  clients that need to connect to ipv6 servers.)  Reversing is the default
-  if this script is named 'inet4to6' (e.g. by a symlink.)
-
-  Use Ctrl-C to stop this program.
-
-  You can also set env. vars INET6TO4_LOOP=1 or INET6TO4_LOOP=BG
-  to have an outer loop restarting this program (BG means do that
-  in the background), and INET6TO4_LOGFILE for a log file.
-  Also set INET6TO4_VERBOSE to verbosity level and INET6TO4_WAITTIME
-  and INET6TO4_PIDFILE (see below.)
-
-   The "INET6TO4_LOOP=BG" and "INET6TO4_LOGFILE=..." env. variables make
-   the tool run reliably as a daemon for very long periods. Read the top
-   part of the script for more information.
-     _________________________________________________________________
-
-   Encrypted Tunnels with IPv6 Support:
-   For SSH tunnelled encrypted VNC connections, one can of course use the
-   IPv6 support in ssh(1).
-
-   For SSL encrypted VNC connections, one possibility is to use the IPv6
-   support in stunnel(1). This includes the built-in support via the
-   -stunnel option. For example:
-  x11vnc -stunnel SAVE -env STUNNEL_LISTEN=:: -env STUNNEL_DEBUG=1 ...
-     _________________________________________________________________
-
-   SSH IPv6 Tricks:
-   It is interesting to note that ssh(1) can do basically the same thing
-   as inet6to4 above by:
-  ssh -g -L 5900:localhost:5901 localhost "printf 'Press Enter to Exit: '; read
- x"
-
-   (where we have x11vnc running via "-rfbport 5901" in this case.)
-
-   Note that one can also make a home-brew SOCKS5 ipv4-to-ipv6 gateway
-   proxy using ssh like this:
-  ssh -D '*:1080' localhost "printf 'Press Enter to Exit: '; read x"
-
-   then specify a proxy like socks://hostname:1080 where hostname is the
-   machine running the above ssh command (add -v to ssh for connection
-   logging info.)
-     _________________________________________________________________
-
-   IPv6 SSVNC Viewer:
-   Our SSVNC VNC Viewer is basically a wrapper for ssh(1) and stunnel(1),
-   and so it already has good IPv6 support because these two commands do.
-   On Unix, MacOSX, and Windows nearly all of the the remaining parts of
-   SSVNC (e.g. the built-in proxying and un-encrypted connections) have
-   been modified to support IPv6 in SSVNC 1.0.26.

-
-
-     _________________________________________________________________
-
-   Chaining ssh's: Note that for use of a ssh gateway and -L redirection
-   to an internal host (e.g. "-L 5900:otherhost:5900") the VNC traffic
-   inside the firewall is not encrypted and you have to manually log into
-   otherhost to start x11vnc. Kyle Amon shows a method where you chain
-   two ssh's together that encrypts all network traffic and also
-   automatically starts up x11vnc on the internal workstation:
-#!/bin/sh
-#
-gateway="example.com"   # or "user@example.com"
-host="labyrinth"        # or "user@hostname"
-user="kyle"
-
-# Need to sleep long enough for all of the passwords and x11vnc to start up.
-# The </dev/null below makes the vncviewer prompt for passwd via popup window.
-#
-(sleep 10; vncviewer -encodings "copyrect tight zrle zlib hextile" \
-    localhost:0 </dev/null >/dev/null) &
-
-# Chain the vnc connection thru 2 ssh's, and connect x11vnc to user's display:
-#
-exec /usr/bin/ssh -t -L 5900:localhost:5900 $gateway \
-     /usr/bin/ssh -t -L 5900:localhost:5900 $host \
-     sudo /usr/bin/x11vnc -localhost -auth /home/$user/.Xauthority \
-         -rfbauth .vnc/passwd -display :0
-
-   Also note the use of sudo(1) to switch to root so that the different
-   user's .Xauthority file can be accessed. See the visudo(8) manpage for
-   details on how to set this up (remove the sudo if you do not want to
-   do this). One can also chain together ssh's for reverse connections
-   with vncviewers using the -listen option. For this case -R would
-   replace the -L (and 5500 the 5900, see the #2 example script above).
-   If the gateway machine's sshd is configured with GatewayPorts=no (the
-   default) then the double chaining of "ssh -R ..." will be required for
-   reverse connections to work.

-
-     _________________________________________________________________
-
-   Misc. Build problems:   We collect here rare build problems some users
-   have reported and the corresponding workarounds. See also the FAQ's on
-   building.
-     _________________________________________________________________
-
-   ENV parameter: One user had a problem where the build script below was
-   failing because his work environment had the ENV variable set to a
-   script that was resetting his PATH so that gcc could no longer be
-   found. Make sure you do not have any ENV or BASH_ENV in your
-   environment doing things like that. Typing "unset ENV", etc. before
-   configuring and building should clear it.
-     _________________________________________________________________
-
-   Bash xpg: One user had his bash shell compiled with
-   --enable-xpg-echo-default that causes some strange behavior with
-   things like echo "\\1 ..." the configure script executes. In
-   particular instead of getting "\1" the non-printable character "^A" is
-   produced, and causes failures at compile time like:
-  ../rfb/rfbconfig.h:9:22: warning: extra tokens at end of #ifndef directive
-
-   The workaround is to configure like this:
-  env CONFIG_SHELL=/bin/sh /bin/sh ./configure
-
-   i.e. avoid using the bash with the misbehavior. A bug has been filed
-   against autoconf to guard against this.
-     _________________________________________________________________
-
-   AIX: one user had to add the "X11.adt" package to AIX to get build
-   header files like XShm.h, etc.
-     _________________________________________________________________
-
-   Ubuntu Feisty Fawn 7.04: In May/2007 one user said he needed to add
-   these packages to compile x11vnc on that Linux distro and version:
-  apt-get install build-essential make bin86 libjpeg62-dev libssl-dev libxtst-d
-ev
-
-   Note that Ubuntu is based on Debian, so perhaps this is the list
-   needed on Debian (testing?) as well. To build in Avahi (mDNS service
-   advertising) support it would appear that libavahi-client-dev is
-   needed as well.
-     _________________________________________________________________
-
-   Exceedingly slow compilation: x11vnc has a couple of files which
-   contain very large "case statements" (over 100 cases) that on some
-   platforms can take a very long time to compile (in extreme cases over
-   an hour). However on 32bit Linux with intel/amd processor and gcc
-   these files usually take less than 10 seconds to compile. For 64bit
-   systems using gcc the problem appears to be much worse.
-
-   The two files with the large number of cases, remote.c and x11vnc.c,
-   have no real need to be optimized (the code is used only very
-   infrequently). So it is fine to supply "-O0" (disables optimization)
-   to CFLAGS when compiling them. However, it is tricky with
-   autoconf/automake to do this (especially since both the compiler and
-   make versions have a big effect).
-
-   So if the compile times are getting too long for you for these two
-   files you will need to manually change some things. First, run
-   configure and when it has finished, edit the generated file
-   x11vnc/Makefile and put these lines at the very top:
-x11vnc-x11vnc.o :  CFLAGS += -O0
-x11vnc-remote.o :  CFLAGS += -O0
-
-   Those lines assume gnu make (gmake) is being used. If you are using
-   another make, say Solaris make, insert these instead:
-x11vnc-x11vnc.o := CFLAGS += -O0
-x11vnc-remote.o := CFLAGS += -O0
-
-   You could write a build shell script that modified the Makefile this
-   way before running make.
-
-   The "-O0" (note it is "capital Oh" followed by "zero") assumes the gcc
-   compiler. If you are using a different compiler you will need to find
-   the command line option to disable optimization, or otherwise have the
-   lines set CFLAGS to the empty string.
-     _________________________________________________________________
-
-   Broken Thread Local Storage on SuSE 9.2: Starting with x11vnc 0.9.8
-   the bundled libvncserver uses the __thread keyword to make some of the
-   encodings (i.e. tight) thread safe (multiple VNC clients can be using
-   tight at the same time in x11vnc -threads mode.) Evidently on the old
-   SuSE 9.2 system the compiler does not support the thread local storage
-   properly. Here is an example build failure:
-tight.c:1126: error: unrecognizable insn:
-(insn:HI 11 10 13 0 (nil) (set (reg/f:SI 59)
-        (const:SI (plus:SI (symbol_ref:SI ("%lpalette"))
-                (const_int 2048 [0x800])))) -1 (nil)
-    (expr_list:REG_EQUAL (const:SI (plus:SI (symbol_ref:SI ("%lpalette"))
-                (const_int 2048 [0x800])))
-        (nil)))
-tight.c:1126: internal compiler error: in extract_insn, at recog.c:2175
-Please submit a full bug report,
-with preprocessed source if appropriate.
-See URL:http://www.suse.de/feedback for instructions.
-
-   The workaround is to disable thread local storage at configure time
-   like this:
-env CPPFLAGS="-DTLS=''" ./configure
-
-   and then build it.

-
-    Sun Ray Notes:
-
-   You can run x11vnc on your (connected or disconnected) SunRay session
-   (Please remember to use settings like -wait 200, -sb 15, and not
-   running a screensaver animation (blank instead) to avoid being a
-   resource hog! x11vnc does induce a lot of memory I/O from polling the
-   X server. It also helps to have a solid background color, e.g.
-   -solid).
-
-   News: Sun Ray Remote Control Toolkit: See the nice set of tools in the
-   Sun Ray Remote Control Toolkit that launch x11vnc automatically for
-   you for certain usage modes.
-
-   You have to know the name of the machine your SunRay session X server
-   is running on (so you can ssh into it and start x11vnc). You also need
-   to know the X11 DISPLAY number for the session: on a SunRay it could
-   be a large number, e.g. :137, since there are many people with X
-   sessions (Xsun processes) on the same machine. If you don't know it,
-   you can get it by running who(1) in a shell on the SunRay server and
-   looking for the dtlocal entry with your username (and if you don't
-   even know which server machine has your session, you could login to
-   all possible ones looking at the who output for your username...).
-
-   I put some code in my ~/.dtprofile script that stores $DISPLAY
-   (including the hostname) in a ~/.sunray_current file at session
-   startup (and deletes it when the X session ends) to make it easy to
-   get at the hostname and X11 display number info for my current X
-   sessions when I ssh in and am about to start x11vnc.
-
-   SunRay Gotcha #1:   Note that even though your SunRay X11 DISPLAY is
-   something like :137, x11vnc still tries for port 5900 as its listening
-   port if it can get it, in which case the VNC display (i.e. the
-   information you supply to the VNC viewer) is something like
-   sunray-server:0   (note the :0 corresponding to port 5900, it is not
-   :137). If it cannot get 5900, it tries for 5901, and so on. You can
-   also try to force the port (and thereby the VNC display) using the
-   -rfbport NNNN option.
-
-   Especially on a busy Sun Ray server it is often difficult to find free
-   ports for both VNC and the HTTP Java applet server to listen on. This
-   script, vnc_findports may be of use for doing this automatically. It
-   suggests x11vnc command line options based on netstat output that
-   lists the occupied ports. It is even more difficult to start
-   vncserver/Xvnc on a busy Sun Ray because then 3 ports (HTTP, VNC, and
-   X11), all separated by 100 are needed! This script, findvncports may
-   be helpful as well. Both scripts start at VNC display :10 and work
-   their way up.
-
-   SunRay Gotcha #2:   If you get an error like:
-        shmget(tile) failed.
-        shmget: No space left on device
-
-   when starting up x11vnc that most likely means all the shared memory
-   (shm) slots are filled up on your machine. The Solaris default is only
-   100, and that can get filled up in a week or so on a SunRay server
-   with lots of users. If the shm slot is orphaned (e.g. creator process
-   dies) the slot is not reclaimed. You can view the shm slots with the
-   "ipcs -mA" command. If there are about 100 then you've probably hit
-   this problem. They can be cleaned out (by the owner or by root) using
-   the ipcrm command. I wrote a script shm_clear that finds the orphans
-   and lists or removes them. Longer term, have your SunRay sysadmin add
-   something like this to /etc/system:
-        set shmsys:shminfo_shmmax = 0x2000000
-        set shmsys:shminfo_shmmni = 0x1000
-
-   SunRay Gotcha #3:   Some SunRay installations have implemented
-   suspending certain applications when a SunRay session is in a
-   disconnected state (e.g. Java Badge pulled out, utdetach, etc). This
-   is a good thing because it limits hoggy or runaway apps from wasting
-   the shared CPU resource. Think how much CPU and memory I/O is wasted
-   by a bunch of Firefox windows running worthless Flash animations while
-   your session is disconnected!
-
-   So some sites have implemented scripts to suspend (e.g. kill -STOP)
-   certain apps when your badge is removed from the SunRay terminal. When
-   you reattach, it kill -CONT them. This causes problems for viewing the
-   detached SunRay session via x11vnc: those suspended apps will not
-   respond (their windows will be blank or otherwise inactive).
-
-   What to do? Well, since you are going to be using the application you
-   might as well unfreeze it rather than starting up a 2nd instance. Here
-   is one way to do it using the kill -CONT mechanism:
-   kill -CONT `ps -ealf | grep ' T ' | grep $LOGNAME | awk '{print $4}'`
-
-   If you want to be a good citizen and re-freeze them before you exit
-   x11vnc this script could be of use:
-#!/bin/sh
-#
-# kill -STOP/-CONT script for x11vnc (or other) SunRay usage ("freezes"
-# certain apps from hogging resources when disconnected).
-#
-# Put here a pattern that matches the apps that are frozen:
-#
-appmatch="java_vm|jre|netscape-bin|firefox-bin|realplay|acroread|mozilla-bin"
-
-if [ "X$1" = "Xfreeze" ]; then
-        pkill -STOP -U $LOGNAME "$appmatch"
-elif [ "X$1" = "Xthaw" ]; then
-        pkill -CONT -U $LOGNAME "$appmatch"
-
-elif [ "$RFB_MODE" = "afteraccept" -a "$RFB_STATE" = "NORMAL" ]; then
-        # a valid x11vnc login.
-        if [ "$RFB_CLIENT_COUNT" = "1" ]; then
-                # only one client present.
-                pkill -CONT -U $LOGNAME "$appmatch"
-        fi
-elif [ "$RFB_MODE" = "gone" -a "$RFB_STATE" = "NORMAL" ]; then
-        # a valid x11vnc login.
-        if [ "$RFB_CLIENT_COUNT" = "0" ]; then
-                # last client present has just left.
-                pkill -STOP -U $LOGNAME "$appmatch"
-        fi
-fi
-exit 0
-
-   If you called the script "goodcitizen" you could type "goodcitizen
-   thaw" to unfreeze them, and then "goodcitizen freeze" to refreeze
-   them. One could also use these x11vnc options "-afteraccept
-   goodcitizen -gone goodcitizen" to do it automatically.
-
-   SunRay Gotcha #4:   Recent versions of the Sun Ray Server Software
-   SRSS (seems to be version 3.0 or 3.1) have a "misfeature" that when
-   the session is disconnected (i.e. badge/smartcard out) the screen
-   locker (xscreensaver) will freeze the X server just when the "Enter
-   Password" dialog box appears. So you cannot unlock the screen remotely
-   via x11vnc!
-
-   Update: please see Bob Doolittle's detailed description of the this
-   issue at the bottom of this section.
-
-   Here "freeze" means "stop other X clients from inserting keyboard and
-   mouse input and from viewing the current contents of the screen". Or
-   something like that; the upshot is x11vnc can't do its normal thing.
-
-   There are several workarounds for this.
-
-   1) The easiest one by far is to put these lines in your
-   $HOME/.dtprofile file:
-SUN_SUNRAY_UTXLOCK_PREF="/usr/openwin/bin/xlock -mode blank"
-export SUN_SUNRAY_UTXLOCK_PREF
-
-   One might argue that xlock isn't particularly "pretty". (Just IMHO,
-   but if something like this not being pretty actually gets in the way
-   of your work I think some introspection may be in order. :-)
-
-   2) The problem has been traced to the pam_sunray.so PAM module.
-   Evidently xscreensaver invokes this pam module and it communicates
-   with utsessiond who in turn instructs the Xsun server to not process
-   any synthetic mouse/keyboard input or to update the screen
-   framebuffer. It is not clear if this is by design (security?) or
-   something else.
-
-   In any event, the problem can be avoided, somewhat drastically, by
-   commenting out the corresponding line in /etc/pam.conf:
-#xscreensaver auth sufficient /opt/SUNWut/lib/pam_sunray.so syncondisplay
-
-   Leave the other xscreensaver pam authentication lines unchanged. The
-   dtsession-SunRay line may also need to be commented out to avoid the
-   problem for CDE sessions. N.B. it is possible the application of a
-   SSRS patch, etc, may re-enable that /etc/pam.conf line. It may be
-   difficult to convince a sysadmin to make this change.
-
-   3) A more forceful way is to kill the xscreensaver process from a
-   shell prompt whenever you connect via x11vnc and the screen is in a
-   locked state:
-pkill -U $LOGNAME '^xscreensaver$'
-
-   And then after you are in be sure to restart it by typing something
-   like:
-xscreensaver &
-
-   You may want to avoid restarting it until you are about to disconnect
-   your VNC viewer (since if it locks the screen while you are working
-   you'll be stuck again).
-
-   3') The above idea can be done a bit more cleanly by having x11vnc do
-   it. Suppose we called the following script xss_killer:
-#!/bin/sh
-#
-# xss_killer: kill xscreensaver after a valid x11vnc client logs in.
-#             Restart xscreensaver and lock it when the last client
-#             disconnects.
-
-PATH=/usr/openwin/bin:/usr/bin:$PATH
-export PATH
-
-if [ "$RFB_MODE" = "afteraccept" -a "$RFB_STATE" = "NORMAL" ]; then
-        # a valid x11vnc login.
-        if [ "$RFB_CLIENT_COUNT" = "1" ]; then
-                # only one client present.
-                pkill -U $LOGNAME '^xscreensaver$'
-                pkill -KILL -U $LOGNAME -f xscreensaver/hacks
-        fi
-elif [ "$RFB_MODE" = "gone" -a "$RFB_STATE" = "NORMAL" ]; then
-        # a valid x11vnc login.
-        if [ "$RFB_CLIENT_COUNT" = "0" ]; then
-                # last client present has just left.
-                xscreensaver -nosplash &
-                sleep 1
-                xscreensaver-command -lock &
-        fi
-fi
-
-   Then we would run x11vnc with these options: "-afteraccept xss_killer
-   -gone xss_killer". The -afteraccept option (introduced in version 0.8)
-   is used to run a command after a vncviewer has successfully logged in
-   (note that this is a VNC login, not a Unix login, so you may not want
-   to do this if you are really paranoid...)
-
-   Note if you use the above script and also plan to Ctrl-C (SIGINT)
-   x11vnc you have to run the xscreensaver in a new process group to
-   avoid killing it as well. One way to do this is via this kludge:
-perl -e 'setpgrp(0,0); exec "xscreensaver -nosplash &"'
-
-   in the above script.
-
-   4) There appears to be a bug in pam_sunray.so in that it doesn't seem
-   to honor the convention that, say, DISPLAY=unix:3 means to use Unix
-   sockets to connect to display 3 on the local machine (this is a bit
-   faster than TCP sockets). Rather, it thinks the display is a non-local
-   one to a machine named "unix" (that usually does not resolve to an IP
-   address).
-
-   Amusingly, this can be used to bypass the pam_sunray.so blocking of
-   Xsun that prevents one from unlocking the screen remotely via x11vnc.
-   One could put something like this in $HOME/.dtprofile to kill any
-   existing xscreensavers and then start up a fresh xscreensaver using
-   DISPLAY=unix:N
-# stop/kill any running xscreensavers (probably not running yet, but to be sure
-)
-xscreensaver-command -exit
-pkill -U $LOGNAME '^xscreensaver$'
-env DISPLAY=`echo $DISPLAY | sed -e 's/^.*:/unix:/'` xscreensaver &
-
-
-   Important: Note that all of the above workarounds side-step the
-   pam_sunray.so PAM module in one way or another. You'll need to see if
-   that is appropriate for your site's SunRay / smartcard usage. Also,
-   these hacks may break other things and so you may want to test various
-   scenarios carefully. E.g. check corner cases like XDMCP/dtremote,
-   NSCM, etc.
-
-
-   Update May 2008: Here is a useful description of this issue from Bob
-   Doolittle who is a developer for Sun Ray at Sun. I don't have the time
-   to digest and distill it and then adjust the above methods to provide
-   a clearer description, so I just include below the description he sent
-   me with the hope that it will help some users:
-
-     In SRSS 4.0 and earlier, the purpose of pam_sunray.so in the "auth"
-     PAM stack of screensavers is to enable NSCM (and, although this is
-     much less commonly used, "SC", which is configured when 3rd-party
-     software is installed to allow smartcards to be used as part of the
-     authentication process) to work. It should have no effect with
-     smartcards. Currently, however, it does block the PAM stack for all
-     sessions, which causes xscreensaver, when it locks a disconnected
-     session, to not process any mouse or keyboard events as you
-     describe (unless xscreensaver does an X server grab, however, other
-     applications should still be able to draw in the session although
-     xscreensaver may be playing tricks like putting a black window on
-     top of everything). In both of the NSCM and SC models,
-     authentication occurs in a separate session before SRSS will
-     reconnect to the user session, in which case pam_sunray.so causes
-     xscreensaver to just unlock the screen without prompting the user
-     to enter their password again. To do this, pam_sunray.so has to
-     block until the session becomes reconnected, so it can query SRSS
-     at that time to determine whether the user has already
-     authenticated or not. In SRSS 4.0 and earlier releases,
-     pam_sunray.so could have been optimized to not block smartcard
-     sessions, although since the session is disconnected this typically
-     isn't important (except in the x11vnc case, as you've observed).
-
-     In SRSS 4.1, however, for increased security the out-of-session
-     authentication model has been extended to *all* session types, so
-     pam_sunray.so will be required in all cases unless users are
-     willing to authenticate twice upon hotdesking (e.g. when their card
-     is inserted). In future, we may do away with pam_sunray.so, and in
-     fact with any traditional screen locker in the user session, since
-     SRSS itself will be providing better security than a screen locker
-     running entirely within the user's X session is capable of
-     providing.
-
-     Your trick of setting DISPLAY to unix:DPY will effectively disable
-     pam_sunray.so (I'm not sure I'd call that a bug - you're going out
-     of your way to do something that wouldn't occur in the normal
-     course of events, and really provides no useful value other than to
-     tickle this behavior in pam_sunray.so). This will mean that, in
-     SRSS 4.0 and earlier releases, users will be prompted for their
-     passwords twice when reconnecting to their sessions for NSCM and SC
-     session types. In 4.1, disabling pam_sunray.so in this way will
-     cause this double-authentication to occur for *all* sessions,
-     including simple smartcard sessions. Users may be willing to pay
-     that price in order to be able to use x11vnc in disconnected
-     sessions. I like this hack, personally. It's a little less
-     convenient than some of the other approaches you describe, but it's
-     lighter-weight and more secure than most of the other approaches,
-     and provides the value of being able to use x11vnc in locked
-     sessions.
-
-     Here are some other minor notes: - I wouldn't recommend storing
-     your display in your .dtprofile, unless you're willing to live with
-     a single session at a time. Personally, I often find myself using
-     several sessions, in several FoGs, for short periods of time so
-     this would certainly break. IMO it's pretty easy to use $DISPLAY to
-     do what you want on the fly, as needed, so I don't think the price
-     of breaking multiple-session functionality would be worth the
-     convenience, to me at least. Here's some ksh/bash syntax to extract
-     the hostname and display number on the fly which you may find
-     useful:
-HOSTNAME=${DISPLAY%:*}
-FULLDPY=${DISPLAY#*:}
-DPYNUM=${FULLDPY%.*}
-
-     A final note may give you some insight into other clever hacks in
-     this area: - Check out utaction. It's a very handy little utility
-     that can be run as a daemon in the user session which will invoke a
-     specified command upon session connects and/or disconnects.
-     Personally, I start one up in my .dtprofile as follows:
-utaction -c $HOME/.srconnectrc -d $HOME/.srdisconnectrc &
-
-     This then allows me to construct a .srconnectrc script containing
-     useful commands I'd like to have run every time I insert my
-     smartcard, and a .srdisconnectrc script of commands to be run every
-     time I remove my smartcard (or, connect/disconnect to my session
-     via NSCM or SC). This can be used for things like notifying a chat
-     client of away status, as well as some of the hacks you've
-     described on your page such as freeze/unfreeze, or perhaps to
-     terminate an xscreensaver and start up a new one with the unix:DPY
-     $DISPLAY specification as you describe (although it probably makes
-     most sense to do this at login time, as opposed to every connect or
-     disconnect event).

-
-   Notes on x11vnc SSL Certificates and Key Management:
-
-   The simplest scheme ("x11vnc -ssl TMP") is where x11vnc generates a
-   temporary, self-signed certificate each time (automatically using
-   openssl(1)) and the VNC viewer client accepts the certificate without
-   question (e.g. user clicks "Yes" in a dialog box. Perhaps the dialog
-   allows them to view the certificate too). Also note stunnel's default
-   is to quietly accept all certificates.
-
-   The encryption this provides protects against all passive sniffing of
-   the VNC traffic and passwords on the network and so it is quite good,
-   but it does not prevent a Man-In-The-Middle active attack: e.g. an
-   attacker intercepts the VNC client stream and sends it his own Public
-   key for SSL negotiation (pretending to be the server). Then it makes a
-   connection to SSL x11vnc itself and forwards the data back and forth.
-   He can see all the traffic and modify it as well.
-
-   Most people don't seem to worry about Man-In-The-Middle attacks these
-   days; they are more concerned about passive sniffing of passwords,
-   etc. Perhaps someday that will change if attack tools are used more
-   widely to perform the attack. NOTE: There are hacker tools like
-   dsniff/webmitm and cain that implement SSL Man-In-The-Middle attacks.
-   They all rely on the client not bothering to check that the cert is
-   valid.
-
-   If you are not worried about Man-In-The-Middle attacks you do not have
-   to read the techniques described in the rest of this document.
-
-   To prevent Man-In-The-Middle attacks, certificates must somehow be
-   verified. This requires the VNC client side have some piece of
-   information that can be used to verify the SSL x11vnc server.
-   Alternatively, although rarely done, x11vnc can verify VNC Clients'
-   certificates, see the -sslverify option that is discussed below.
-
-   There are a number of ways to have the client authenticate the SSL
-   x11vnc server. The quickest way perhaps would be to copy (safely) the
-   certificate x11vnc prints out:
-26/03/2006 21:12:00 Creating a temporary, self-signed PEM certificate...
-...
------BEGIN CERTIFICATE-----

-NTIwLjQxMTE2OTEPMA0GA1UEChMGeDExdm5jMS4wLAYDVQQDEyV4MTF2bmMtU0VM
-(more lines) ...
------END CERTIFICATE-----
-
-   to the client machine(s) and have the client's SSL machinery (e.g.
-   stunnel, Web Browser, or Java plugin) import the certificate. That way
-   when the connection to x11vnc is made the client can verify that is it
-   the desired server on the other side of the SSL connection.
-
-   So, for example suppose the user is using the SSL enabled Java VNC
-   Viewer and has incorporated the x11vnc certificate into his Web
-   browser on the viewing side. If he gets a dialog that the certificate
-   is not verified he knows something is wrong. It may be a
-   Man-In-The-Middle attack, but more likely x11vnc certificate has
-   changed or expired or his browser was reinstalled and/or lost the
-   certificate, etc, etc.
-
-   As another example, if the user was using stunnel with his VNC viewer
-   (this is mentioned in this FAQ), e.g. STUNNEL.EXE on Windows, then he
-   would have to set the "CAfile = path-to-the-cert" and "verify = 2"
-   options in the stunnel.conf file before starting up the tunnel. If a
-   x11vnc certificate cannot be verified, stunnel will drop the
-   connection (and print a failure message in its log file).
-
-   A third example, using the VNC viewer on Unix with stunnel the wrapper
-   script can be used this way: "ss_vncviewer -verify ./x11vnc.crt
-   far-away.east:0" where ./x11vnc.crt is the copied certificate x11vnc
-   printed out.
-
-   As fourth example, our SSVNC enhanced tightvnc viewer can also use
-   these certificate files for server authentication. You can load them
-   via the SSVNC 'Certs...' dialog and set 'ServerCert' to the
-   certificate file you safely copied there.
-
-   Note that in principle the copying of the certificate to the client
-   machine(s) itself could be altered by a Man-In-The-Middle attack! You
-   can't win; it is very difficult to be completely secure. It is
-   unlikely the attacker could predict how you were going to send it
-   unless you had, say, done it many times before the same way. SSH is a
-   very good way to send it (but of course it too depends on public keys
-   being sent unaltered between the two machines!).
-
-   If you are really paranoid, I'm sure you'll figure out a really good
-   way to transport the certificates. See the Certificate Authority
-   scheme below for a way to make this easier (you just have to do it
-   once).
-
-     _________________________________________________________________
-
-   Saving SSL certificates and keys:
-
-   Now, it would be very inconvenient to copy the new temporary
-   certificate every time x11vnc is run in SSL mode. So for convenience
-   there is the "SAVE" keyword to instruct x11vnc to save the certificate
-   it creates:
-  x11vnc -ssl SAVE -display :0 ...
-
-   This behavior is now the default, you must use "TMP" for a temporary
-   one. It will save the certificate and private key in these files:
-  ~/.vnc/certs/server.crt
-  ~/.vnc/certs/server.pem
-
-   The ".crt" file contains only the certificate and should be safely
-   copied to the VNC Viewer machine(s) that will be authenticating the
-   x11vnc server. The ".pem" file contains both the certificate and the
-   private key and should be kept secret. (If you don't like the default
-   location ~/.vnc/certs, e.g. it is on an NFS share and you are worried
-   about local network sniffing, use the -ssldir dir option to point to a
-   different directory.)
-
-   So the next time you run "x11vnc -ssl SAVE ..." it will read the
-   server.pem file directly instead of creating a new one.
-
-   You can manage multiple SSL x11vnc server keys in this simple way by
-   using:
-  x11vnc -ssl SAVE-key2 -display :0 ...
-
-   etc, where you put whatever name you choose for the key after "SAVE-".
-   E.g. "-ssl SAVE-fred".
-
-   Also, if you want to be prompted to possibly change the made up names,
-   etc. that x11vnc creates (e.g. "x11vnc-SELF-SIGNED-CERT-7762" for the
-   CommonName) for the certificates distinguished name (DN), then use
-   "x11vnc -ssl SAVE_PROMPT ...", "x11vnc -ssl SAVE_PROMPT-fred ..." etc.
-   when you create the key the first time.
-
-   Tip: when prompting, if you choose the CommonName entry to be the full
-   internet hostname of the machine the clients will be connecting to
-   then that will avoid an annoying dialog box in their Web browsers that
-   warn that the CommonName doesn't match the hostname.
-
-     _________________________________________________________________
-
-   Passphrases for server keys:
-
-   Well, since now with the "SAVE" keyword the certificate and key will
-   be longer lived, one can next worry about somebody stealing the
-   private key and pretending to be the x11vnc server! How to guard
-   against this?
-
-   The first is that the file is created with perms 600 (i.e. -rw-------)
-   to make it harder for an untrusted user to copy the file. A better way
-   is to also encrypt the private key with a passphrase. You are prompted
-   whether you want to do this or not when the key is first created under
-   "-ssl SAVE" mode ("Protect key with a passphrase? y/n"). It is
-   suggested that you use a passphrase. The inconvenience is every time
-   you run "x11vnc -ssl SAVE ..." you will need to supply the passphrase
-   to access the private key:
-  06/04/2006 11:39:11 using PEM /home/runge/.vnc/certs/server.pem  0.000s
-
-  A passphrase is needed to unlock an OpenSSL private key (PEM file).
-  Enter passphrase>
-
-   before x11vnc can continue.
-
-     _________________________________________________________________
-
-   Being your own Certificate Authority:
-
-   A very sophisticated way that scales well if the number of users is
-   large is to use a Certificate Authority (CA) whose public certificate
-   is available to all of the VNC clients and whose private key has been
-   used to digitally sign the x11vnc server certificate(s).
-
-   The idea is as follows:
-     * A special CA cert and key is generated.
-     * Its private key is always protected by a good passphrase since it
-       is only used for signing.
-     * The CA cert is (safely) distributed to all machines where VNC
-       clients will run.
-     * One or more x11vnc server certs and keys are generated.
-     * The x11vnc server cert is signed with the CA private key.
-     * x11vnc is run using the server key. (e.g. "-ssl SAVE")
-     * VNC clients (viewers) can now authenticate the x11vnc server
-       because they have the CA certificate.
-
-   The advantage is the CA cert only needs to be distributed once to the
-   various machines, that can be done even before x11vnc server certs are
-   generated.
-
-   As above, it is important the CA private key and the x11vnc server key
-   are kept secret, otherwise someone could steal them and pretend to be
-   the CA or the x11vnc server if they copied the key. It is recommended
-   that the x11vnc server keys are also protected via a passphrase (see
-   the previous section).
-
-   Optionally, VNC viewer certs and keys could also be generated to
-   enable the x11vnc server to authenticate each client. This is not
-   normally done (usually a simple viewer password scheme is used), but
-   this can be useful in some situations. These optional steps go like
-   this:
-     * One or more VNC client certs and keys are generated.
-     * These VNC client certs are signed with the CA private key.
-     * The VNC client certs+keys are safely distributed to the
-       corresponding client machines.
-     * x11vnc is told to verify clients by using the CA cert. (e.g.
-       "-sslverify CA")
-     * When VNC clients (viewers) connect, they must authenticate
-       themselves to x11vnc by using their client key.
-
-   Again, it is a good idea if the client private keys are protected with
-   a passphrase, otherwise if stolen they could be used to gain access to
-   the x11vnc server. Once distributed to the client machines, there is
-   no need to keep the client key on the CA machine that generated and
-   signed it. You can keep the client certs if you like because they are
-   public.
-
-     _________________________________________________________________
-
-   How to do the above CA steps with x11vnc:
-
-   Some utility commands are provided to ease the cert+key creation,
-   signing, and management: -sslGenCA, -sslGenCert, -sslDelCert,
-   -sslEncKey, -sslCertInfo. They basically run the openssl(1) command
-   for you to manage the certs/keys. It is required that openssl(1) is
-   installed on the machine and available in PATH. All commands can be
-   pointed to an alternate toplevel certificate directory via the -ssldir
-   option if you don't want to use the default ~/.vnc/certs.
-
-   1) To generate your Certificate Authority (CA) cert and key run this:
-  x11vnc -sslGenCA
-
-   Follow the prompts, you can modify any informational strings you care
-   to. You will also be required to encrypt the CA private key with a
-   passphrase. This generates these files:
-  ~/.vnc/certs/CA/cacert.pem             (the CA public certificate)
-  ~/.vnc/certs/CA/private/cakey.pem      (the encrypted CA private key)
-
-   If you want to use a different directory use -ssldir It must supplied
-   with all subsequent SSL utility options to point them to the correct
-   directory.
-
-   2) To generate a signed x11vnc server cert and key run this:
-  x11vnc -sslGenCert server
-
-   As with the CA generation, follow the prompts and you can modify any
-   informational strings that you care to. This will create the files:
-  ~/.vnc/certs/server.crt             (the server public certificate)
-  ~/.vnc/certs/server.pem             (the server private key + public cert)
-
-   It is recommended to protect the server private key with a passphrase
-   (you will be prompted whether you want to). You will need to provide
-   it whenever you start x11vnc using this key.
-
-   3) Start up x11vnc using this server key:
-  x11vnc -ssl SAVE -display :0 ...
-
-   (SAVE corresponds to server.pem, see -sslGenCert server somename info
-   on creating additional server keys, server-somename.crt ...)
-
-   4) Next, safely copy the CA certificate to the VNC viewer (client)
-   machine(s). Perhaps:
-  scp ~/.vnc/CA/cacert.pem clientmachine:.
-
-   5) Then the tricky part, make it so the SSL VNC Viewer uses this
-   certificate! There are a number of ways this might be done, it depends
-   on what your client and/or SSL tunnel is. Some examples:
-
-   For the SSL Java VNC viewer supplied with x11vnc in
-   classes/ssl/VncViewer.jar or classes/ssl/SignedVncViewer.jar:
-     * Import the cacert.pem cert into your Web Browser (e.g. Edit ->
-       Preferences -> Privacy & Security -> Manage Certificates ->
-       WebSites -> Import)
-     * Or Import the cacert.pem cert into your Java Plugin (e.g. run
-       ControlPanel, then Security -> Certificates -> Secure Site ->
-       Import)
-
-   When importing, one would give the browser/java-plugin the path to the
-   copied cacert.pem file in some dialog. Note that the Web browser or
-   Java plugin is used for the server authentication. If the user gets a
-   "Site not verified" message while connecting he should investigate
-   further.
-
-   For the use of stunnel (e.g. on Windows) one would add this to the
-   stunnel.conf:
-  # stunnel.conf:
-  client = yes
-  options = ALL
-  CAfile = /path/to/cacert.pem          # or maybe C:\path\to\cacert.pem
-  [myvncssl]
-  accept = 5901
-  connect = far-away.east:5900
-
-   (then point the VNC viewer to localhost:1).
-
-   Here is an example for the Unix stunnel wrapper script ss_vncviewer in
-   our SSVNC package:
-  ss_vncviewer -verify ./cacert.pem far-away.east:0
-
-   Our SSVNC enhanced tightvnc viewer GUI can also use the certificate
-   file for server authentication. You can load it via the SSVNC
-   'Certs...' dialog and set 'ServerCert' to the cacert.pem file you
-   safely copied there.
-
-     _________________________________________________________________
-
-   Tricks for server keys:
-
-   To create additional x11vnc server keys do something like this:
-  x11vnc -sslGenCert server myotherkey
-
-   and use it this way:
-  x11vnc -ssl SAVE-myotherkey ...
-
-   The files will be ~/.vnc/certs/server-myotherkey.{crt,pem}
-
-   You can also create a self-signed server key:
-  x11vnc -sslGenCert server self:third_key
-
-   and use it this way:
-  x11vnc -ssl SAVE-self:third_key ...
-
-   This key is not signed by your CA. This can be handy to have a key set
-   separate from your CA when you do not want to create a 2nd CA
-   cert+key.
-
-     _________________________________________________________________
-
-   Using external CA's:
-
-   You don't have to use your own CA cert+key, you can use a third
-   party's instead. Perhaps you have a company-wide CA or you can even
-   have your x11vnc certificate signed by a professional CA (e.g.
-   www.thawte.com or www.verisign.com or perhaps the free certificate
-   service www.startcom.org or www.cacert.org).
-
-   The advantage to doing this is that the VNC client machines will
-   already have the CA certificates installed and you don't have to
-   install it on each machine.
-
-   To generate an x11vnc server cert+key this way you should generate a
-   "request" for a certicate signing something like this (we use the name
-   "external" in this example, it could be anything you want):
-  x11vnc -sslGenCert server req:external
-
-   This will create the request file:
-  ~/.vnc/certs/server-req:external.req
-
-   Which you should send to the external CA. When you get the signed
-   certificate back from them, save it in the file:
-  ~/.vnc/certs/server-req:external.crt
-
-   and create the .pem this way:
-  mv  ~/.vnc/certs/server-req:external.key    ~/.vnc/certs/server-req:external.
-pem
-  chmod 600 ~/.vnc/certs/server-req:external.pem
-  cat ~/.vnc/certs/server-req:external.crt >> ~/.vnc/certs/server-req:external.
-pem
-
-   You also rename the two files (.crt and .pem) to have a shorter
-   basename if you like. E.g.:
-  mv  ~/.vnc/certs/server-req:external.pem  ~/.vnc/certs/server-ext.pem
-  mv  ~/.vnc/certs/server-req:external.crt  ~/.vnc/certs/server-ext.crt
-
-   and the use via "x11vnc -ssl SAVE-ext ...", etc.
-
-   On the viewer side make sure the external CA's certificate is
-   installed an available for the VNC viewer software you plan to use.
-
-     _________________________________________________________________
-
-   Using Client Keys for Authentication:
-
-   You can optionally create certs+keys for your VNC client machines as
-   well. After distributing them to the client machines you can have
-   x11vnc verify the clients using SSL. Here is how to do this:
-
-  x11vnc -sslGenCert client dilbert
-  x11vnc -sslGenCert client wally
-  x11vnc -sslGenCert client alice
-  ...
-
-   As usual, follow the prompts if you want to change any of the info
-   field values. As always, it is a good idea (although inconvenient) to
-   protect the private keys with a passphrase. These files are created:
-  ~/.vnc/certs/clients/dilbert.crt
-  ~/.vnc/certs/clients/dilbert.pem
-  ...
-
-   Note that these are kept in a clients subdirectory.
-
-   Next, safely copy the .pem files to each corresponding client machine
-   and incorporate them into the VNC viewer / SSL software (see the ideas
-   mentioned above for the CA and server keys). The only difference is
-   these certificates might be referred to as "My Certificates" or
-   "Client Certificates". They are used for client authentication (which
-   is relatively rare for SSL).
-
-   After copying them you can delete the clients/*.pem files for extra
-   safety because the private keys are not needed by the x11vnc server.
-   You don't really need the clients/*.crt files either (because they
-   have been signed by the CA). But they could come in handy for tracking
-   or troubleshooting, etc.
-
-   Now start up x11vnc and instruct it to verify connecting clients via
-   SSL and the CA cert:
-  x11vnc -ssl SAVE -sslverify CA
-
-   The "CA" special token instructs x11vnc to use its CA signed certs for
-   verification.
-
-   For arbitrary self-signed client certificates (no CA) it might be
-   something like this:
-  x11vnc -ssl SAVE -sslverify path/to/client.crt
-  x11vnc -ssl SAVE -sslverify path/to/client-hash-dir
-  x11vnc -ssl SAVE -sslverify path/to/certs.txt
-
-   Where client.crt would be an individual client certificate;
-   client-hash-dir a directory of file names based on md5 hashes of the
-   certs (see -sslverify); and certs.txt signifies a single file full of
-   client certificates.
-
-   Finally, connect with your VNC viewer using the key. Here is an
-   example for the Unix stunnel wrapper script ss_vncviewer: using client
-   authentication (and the standard server authentication with the CA
-   cert):
-  ss_vncviewer -mycert ./dilbert.pem -verify ./cacert.pem far-away.east:0
-
-   Our SSVNC enhanced tightvnc viewer can also use these openssl .pem
-   files (you can load them via Certs... -> MyCert dialog).
-
-   It is also possible to use -sslverify on a per-client key basis, and
-   also using self-signed client keys (x11vnc -sslGenCert client
-   self:dilbert)
-
-   Now a tricky part is to get Web browsers or Java Runtime to import and
-   use the openssl .pem cert+key files. See the next paragraph on how to
-   convert them to pkcs12 format. If you find a robust way to import them
-   and and get them to use the cert please let us know!
-
-   Here is how to convert our openssl crt/pem files to pkcs12 format
-   (contains both the client certificate and key) that can be read by Web
-   browsers and Java for use in client authentication:
-  openssl pkcs12 -export -in mycert.crt -inkey mycert.pem -out mycert.p12
-
-   it will ask for a passphrase to protect mycert.p12. Some software
-   (e.g. Java ControlPanel) may require a non-empty passphrase. Actually,
-   since our .pem contains both the certificate and private key, you
-   could just supply it for the -in and remove the -inkey option. It
-   appears that for certificates only importing, our .crt file is
-   sufficient and can be read by Mozilla/Firefox and Java...
-
-   If you have trouble getting your Java Runtime to import and use the
-   cert+key, there is a workaround for the SSL-enabled Java applet. On
-   the Web browser URL that retrieves the VNC applet, simply add a
-   "/?oneTimeKey=..." applet parameter (see ssl-portal for more details
-   on applet parameters; you don't need to do the full portal setup
-   though). The value of the oneTimeKey will be the very long string that
-   is output of the onetimekey program found in the classes/ssl x11vnc
-   directory. Or you can set oneTimeKey=PROMPT in which case the applet
-   will ask you to paste in the long string. These scheme is pretty ugly,
-   but it works. A nice application of it is to make one time keys for
-   users that have already logged into a secure HTTPS site via password.
-   A cgi program then makes a one time key for the logged in user to use:
-   it is passed back over HTTPS as the applet parameter in the URL and so
-   cannot be sniffed. x11vnc is run to use that key via -sslverify.
-
-   Update: as of Apr 2007 in the 0.9.1 x11vnc tarball there is a new
-   option setting "-users sslpeer=" that will do a switch user much like
-   -unixpw does, but this time using the emailAddress field of the
-   Certificate subject of the verified Client. This mode requires
-   -sslverify turned on to verify the clients via SSL. This mode can be
-   useful in situations using -create or -svc where a new X server needs
-   to be started up as the authenticated user (but unlike in -unixpw
-   mode, the unix username is not obviously known).
-
-     _________________________________________________________________
-
-   Revoking Certificates:
-
-   A large, scaled-up installation may benefit from being able to revoke
-   certificates (e.g. suppose a user's laptop with a vnc client or server
-   key is compromised.) You can use this option with x11vnc: -sslCRL. See
-   the info at that link for a guide on what openssl(1) commands you will
-   need to run to revoke a certificate.
-
-     _________________________________________________________________
-
-   Additional utlities:
-
-   You can get information about your keys via -sslCertInfo. These lists
-   all your keys:
-  x11vnc -sslCertInfo list
-  x11vnc -sslCertInfo ll
-
-   (the latter is long format).
-
-   These print long output, including the public certificate, for
-   individual keys:
-  x11vnc -sslCertInfo server
-  x11vnc -sslCertInfo dilbert
-  x11vnc -sslCertInfo all             (every key, very long)
-
-   If you want to add a protecting passphrase to a key originally created
-   without one:
-  x11vnc -sslEncKey SAVE
-  x11vnc -sslEncKey SAVE-fred
-
-   To delete a cert+key:
-  x11vnc -sslDelCert SAVE
-  x11vnc -sslDelCert SAVE-fred
-  x11vnc -sslDelCert wally
-
-   (but rm(1) will be just as effective).
-
-     _________________________________________________________________
-
-   Chained Certificates:
-
-   There is increasing interest in using chained CA's instead of a single
-   CA. The merits of using chained CA's are not described here besides to
-   say its use may make some things easier when a certificate needs to be
-   revoked.
-
-   x11vnc supports chained CA certificates. We describe a basic use case
-   here.
-
-   Background: Of course the most straight forward way to use SSL with
-   x11vnc is to use no CA at all (see above): a self-signed certificate
-   and key is used and its certificate needs to be safely copied to the
-   client side. This is basically the same as the SSH style of managing
-   keys. Next level up, one can use a single CA to sign server keys: then
-   only the CA's certificate needs to be safely copied to the client
-   side, this can happen even before any server certs are created (again,
-   see all of the discussion above.)
-
-   With a certificate chain there are two or more CA's involved. Perhaps
-   it looks like this:
-  root_CA ---> intermediate_CA ---> server_cert
-
-   Where the arrow basically means "signs".
-
-   In this usage mode the client (viewer-side) will have root_CA's
-   certificate available for verifying (and nothing else.) If the viewer
-   only received server_cert's certificate, it would not have enough info
-   to verify the server. The client needs to have intermediate_CA's cert
-   as well. The way to do this with x11vnc (i.e. an OpenSSL using app) is
-   to concatenate the server_cert's pem and the intermediate_CA's
-   certificate together.
-
-   For example, suppose the file intermediate_CA.crt had
-   intermediate_CA's certificate. And suppose the file server_cert.pem
-   had the server's certificate and private key pair as described above
-   on this page. We need to do this:
-  cat intermediate_CA.crt >> server_cert.pem
-
-   (Note: the order of the items inside the file matters; intermediate_CA
-   must be after the server key and cert) and then we run x11vnc like
-   this:
-  x11vnc -ssl ./server_cert.pem ...
-
-   Then, on the VNC viewer client side, the viewer authenticates the
-   x11vnc server by using root_CA's certificate. Suppose that is in a
-   file named root_CA.crt, then using the SSVNC wrapper script
-   ss_vncviewer (which is also included in the SSVNC package) as our
-   example, we have:
-  ss_vncviewer -verify ./root_CA.crt hostname:0
-
-   (where "hostname" is the machine where x11vnc is running.) One could
-   also use the SSVNC GUI setting Certs -> ServerCert to the root_CA.crt
-   file. Any other SSL enabled VNC viewer would use root_CA.crt in a
-   similar way.
-     _________________________________________________________________
-
-   Creating Chained Certificates:
-
-   Here is a fun example using VeriSign's "Trial Certificate" program.
-   Note that VeriSign has a Root CA and also an Intermediate CA and uses
-   the latter to sign customers certificates. So this provides an easy
-   way to test out the chained certificates mechanism with x11vnc.
-
-   First we created a test x11vnc server key:
-  openssl genrsa -out V1.key 1024
-
-   then we created a certificate signing request (CSR) for it:
-  openssl req -new -key V1.key -out V1.csr
-
-   (we followed the prompts and supplied information for the various
-   fields.)
-
-   Then we went to VeriSign's page http://www.verisign.com/ssl/index.html
-   and clicked on "FREE TRIAL" (the certificate is good for 14 days.) We
-   filled in the forms and got to the point where it asked for the CSR
-   and so we pasted in the contents of the above V1.csr file. Then, after
-   a few more steps, VeriSign signed and emailed us our certificate.
-
-   The VeriSign Trial certificates were found here:
-  http://www.verisign.com/support/verisign-intermediate-ca/Trial_Secure_Server_
-Root/index.html
-  http://www.verisign.com/support/verisign-intermediate-ca/trial-secure-server-
-intermediate/index.html
-
-   The former was pasted into a file V-Root.crt and the latter was pasted
-   into V-Intermediate.crt
-
-   We pasted our Trial certificate that VeriSign signed and emailed to us
-   into a file named V1.crt and then we typed:
-  cat V1.key V1.crt > V1.pem
-  cat V1.pem V-Intermediate.crt > V1-combined.pem
-  chmod 600 V1.pem V1-combined.pem
-
-   So now the file V1-combined.pem has our private key and (VeriSign
-   signed) certificate and VeriSign's Trial Intermediate certificate.
-
-   Next, we start x11vnc:
-  x11vnc -ssl ./V1-combined.pem ...
-
-   and finally, on the viewer side (SSVNC wrapper script example):
-  ss_vncviewer -verify ./V-Root.crt hostname:0
-
-   One will find that only that combination of certs and keys will work,
-   i.e. allow the SSL connection to be established. Every other
-   combination we tried failed (note that ss_vncviewer uses the external
-   stunnel command to handle the SSL so we are really testing stunnel's
-   SSL implementation on the viewer side); and so the system works as
-   expected.
-     _________________________________________________________________
-
-   VNC Client Authentication using Certificate Chains:
-
-   Now, going the other way around with the client authenticating himself
-   via this chain of SSL certificates, x11vnc is run this way:
-  x11vnc -ssl SAVE -sslverify ./V-Root.crt ...
-
-   (note since the server must always supply a cert, we use its normal
-   self-signed, etc., one via "-ssl SAVE" and use the VeriSign root cert
-   for client authentication via -sslverify. The viewer must now supply
-   the combined certificates, e.g.:
-  ss_vncviewer -mycert ./V1-combined.pem hostname:0
-     _________________________________________________________________
-
-   Using OpenSSL and x11vnc to create Certificate Chains:
-
-   Although the x11vnc CA mechanism (-sslGenCA and -sslGenCert; see
-   above) was designed to only handle a single root CA (to sign server
-   and/or client certs) it can be coerced into creating a certificate
-   chain by way of an extra openssl(1) command.
-
-   We will first create two CA's via -sslGenCA; then use one of these CA
-   to sign the other; create a new (non-CA) server cert; and append the
-   intermediate CA's cert to the server cert to have everything needed in
-   the one file.
-
-   Here are the commands we ran to do what the previous paragraph
-   outlines.
-
-   First we create the two CA's, called CA_root and CA_Intermediate here,
-   in separate directories via x11vnc:
-  x11vnc -ssldir ~/CA_Root -sslGenCA
-     (follow the prompts, we included "CA_Root", e.g. Common Name, to aid ident
-ifying it)
-
-  x11vnc -ssldir ~/CA_Intermediate -sslGenCA
-     (follow the prompts, we included "CA_Intermediate", e.g. Common Name, to a
-id identifying it)
-
-   Next backup CA_Intermediate's cert and then sign it with CA_Root:
-  mv ~/CA_Intermediate/CA/cacert.pem ~/CA_Intermediate/CA/cacert.pem.ORIG
-  cd ~/CA_Root
-  openssl ca -config ./CA/ssl.cnf -policy policy_anything -extensions v3_ca -no
-text -ss_cert ~/CA_Intermediate/CA/cacert.pem.ORIG -out ~/CA_Intermediate/CA/ca
-cert.pem
-
-   Note that it is required to cd to the ~/CA_Root directory and run the
-   openssl command from there.
-
-   You can print out info about the cert you just modified by:
-  openssl x509 -noout -text -in ~/CA_Intermediate/CA/cacert.pem
-
-   Now we create an x11vnc server cert named "test_chain" that is signed
-   by CA_Intermediate:
-  x11vnc -ssldir ~/CA_Intermediate -sslGenCert server test_chain
-     (follow the prompts)
-
-   You can print out information about this server cert just created via
-   this command:
-  x11vnc -ssldir ~/CA_Intermediate -sslCertInfo SAVE-test_chain
-
-   This will tell you the full path to the server certificate, which is
-   needed because we need to manually append the CA_Intermediate cert for
-   the chain to work:
-  cat ~/CA_Intermediate/CA/cacert.pem >> ~/CA_Intermediate/server-test_chain.pe
-m
-
-   Now we are finally ready to use it. We can run x11vnc using this
-   server cert+key by either this command:
-  x11vnc -ssldir ~/CA_Intermediate -ssl SAVE-test_chain ...
-
-   or this command:
-  x11vnc -ssl ~/CA_Intermediate/server-test_chain.pem ...
-
-   since they are equivalent (both load the same pem file.)
-
-   Finally we connect via VNC viewer that uses CA_Root to verify the
-   server. As before we use ss_vncviewer:
-  ss_vncviewer -verify ~/CA_Root/CA/cacert.pem hostname:0
-
-   Client Certificates (see above) work in a similar manner.
-
-   So although it is a little awkward with the extra steps (e.g.
-   appending the CA_Intermediate cert) it is possible. If you want to do
-   this entirely with openssl(1) you will have to learn the openssl
-   commands corresponding to -genCA and -genCert. You may be able to find
-   guides on the Internet to do this. Starting with x11vnc 0.9.10, you
-   can have it print out the wrapper scripts it uses via: -sslScripts
-   (you will still need to fill in a few pieces of information; ask if it
-   is not clear from the source code.)

-
-   Using Apache as an SSL Gateway to multiple x11vnc servers inside a
-   firewall:
-
-   Background:
-
-   The typical way to allow access to x11vnc (or any other VNC server)
-   running on multiple workstations inside a firewall is via SSH. The
-   user somewhere out on the Internet logs in to the SSH gateway machine
-   and uses port forwarding (e.g. ssh -t -L 5900:myworkstation:5900
-   user@gateway) to set up the encrypted channel that VNC is then
-   tunneled through. Next he starts up the VNC viewer on the machine
-   where he is sitting directed to the local tunnel port (e.g.
-   localhost:0).
-
-   The SSH scheme is nice because it is a widely used and well tested
-   login technique for users connecting to machines inside their company
-   or home firewall. For VNC access it is a bit awkward, however, because
-   SSH needs to be installed on the Viewer machine and the user usually
-   has to rig up his own port redirection plumbing (however, see our
-   other tool).
-
-   Also, some users have restrictive work environments where SSH and
-   similar applications are prohibited (i.e. only outgoing connections to
-   standard WWW ports from a browser are allowed, perhaps mediated by a
-   proxy server). These users have successfully used the method described
-   here for remote access.
-
-   With the SSL support in x11vnc and the SSL enabled Java VNC viewer
-   applet, a convenient and secure alternative exists that uses the
-   Apache webserver as a gateway. The idea is that the company or home
-   internet connection is already running apache as a web server (either
-   SSL or non-SSL) and we add to it the ability to act as a gateway for
-   SSL VNC connections. The only thing needed on the Viewer side is a
-   Java enabled Web Browser: the user simply enters a URL that starts the
-   entire VNC connection process. No VNC or SSH specific software needs
-   to be installed on the viewer side machine.
-
-   The stunnel VNC viewer stunnel wrapper script provided (ss_vncviewer)
-   can also take advantage of the method described here with its -proxy
-   option.
-
-     _________________________________________________________________
-
-   Simpler Solutions: This apache SSL VNC portal solution may be too much
-   for you. It is mainly intended for automatically redirecting to
-   MULTIPLE workstations inside the firewall. If you only have one or two
-   inside machines that you want to access, the method described here is
-   overly complicated! See below for some simpler (and still non-SSH)
-   encrypted setups.
-
-   Also see the recent (Mar/2010) desktop.cgi x11vnc desktop web login
-   CGI script that achieves much of what the method describes here
-   (especially if its 'port redirection' feature is enabled.)
-     _________________________________________________________________
-
-
-
-   There are numerous ways to achieve this with Apache. We present one of
-   the simplest ones here.
-
-   Important: these sorts of schemes allow incoming connections from
-   anywhere on the Internet to fixed ports on machines inside the
-   firewall. Care must be taken to implement and test thoroughly. If one
-   is paranoid one can (and should) add extra layers of protection. (e.g.
-   extra passwords, packet filtering, SSL certificate verification, etc).
-
-   Also, it is easy to miss the point that unless precautions are taken
-   to verify SSL Certificates, then the VNC Viewer is vulnerable to
-   man-in-the-middle attacks (but not to the more common passive sniffing
-   attacks). Note that there are hacker tools like dsniff/webmitm and
-   cain that implement SSL Man-In-The-Middle attacks. They rely on the
-   client not bothering to check the cert.
-     _________________________________________________________________
-
-   The Holy Grail: a single https port (443)
-
-   Before we discuss the self-contained apache examples here, we want to
-   mention that many x11vnc users who read this page and implement the
-   apache SSL VNC portal ask for something that (so far) seems difficult
-   or impossible to do entirely inside apache:
-     * A single port, 443 (the default https:// port), is open to the
-       Internet
-     * It is HTTPS/SSL encrypted
-     * It handles both VNC traffic and Java VNC Applet downloads.
-     * And the server can also serve normal HTTPS webpages, CGI, etc.
-
-   It is the last item that makes it tricky (otherwise the method
-   described on this page will work). If you are interested in such a
-   solution and are willing to run a separate helper program
-   (connect_switch) look here. Also, see this apache patch.
-     _________________________________________________________________
-
-   Example:
-
-   The scheme described here sets up apache on the firewall/gateway as a
-   regular Web proxy into the intranet and allows connections to a single
-   fixed port on a limited set of machines.
-
-   The configuration described in this section does not use the mod_ssl
-   apache module (the optional configuration described in the section
-   "Downloading the Java applet to the browser via HTTPS" does take
-   advantage of mod_ssl)
-
-   In this example suppose the gateway machine running apache is named
-   "www.gateway.east" (e.g. it may also provide normal web service). We
-   also choose the Internet-facing port for this VNC service to be port
-   563. One could choose any port, including the default HTTP port 80.
-
-   Detail: We choose 563 because it is the rarely used SNEWS port that is
-   often allowed by Web proxies for the CONNECT method. The idea is the
-   user may be coming out of another firewall using a proxy (not the one
-   we describe here, that is, the case when two proxies are involved,
-   e.g. one at work and another Apache (described here) at home
-   redirecting into our firewall; the "double proxy" or "double firewall"
-   problem). Using port 563 simplifies things because CONNECT's to it are
-   usually allowed by default.
-
-   We also assume all of the x11vnc servers on the internal machines are
-   all listening on port 5915 ("-rfbport 5915") instead of the default
-   5900. This is to limit any unintended proxy redirections to a lesser
-   used port, and also to stay out of the way of normal VNC servers on
-   the same machines. One could obviously implement a scheme that handles
-   different ports, but we just discuss this simple setup here.
-
-   So we basically assume x11vnc has been started this way on all of the
-   workstations to be granted VNC access:
-  x11vnc -ssl SAVE -http -display :0 -forever -rfbauth ~/.vnc/passwd -rfbport 5
-915

-</VirtualHost>
-
-   Then restart apache (perhaps: "apachectl stop; apachectl start").
-
-   Note that the listing of allowed internal workstations is done in an
-   external file (/dist/apache/conf/vnc.hosts in the example above), the
-   format is like this:
-# allowed vnc hosts file:
-hostname1  15
-hostname2  15
-...
-
-   You list the hostname and the VNC display (always 15 in our example).
-   Only to these hosts will the external VNC viewers be able to connect
-   to (via the HTTP CONNECT method).
-
-   The above setup requires mod_rewrite and mod_proxy be enabled in the
-   apache web server. In this example they are loaded as modules (and
-   note that mod_rewrite must be listed before mod_proxy);
-
-   The user at the Java enabled Web browser would simply enter this URL
-   into the browser:
-   http://www.gateway.east:563/vnc/host2
-
-   to connect to internal workstation host2, etc.
-
-   Important: do not put a trailing "/" on the URL, since that will
-   defeat the RewriteRules that look for the hostname at the very end.
-
-   There will be a number of SSL certificate, etc, dialogs he will have
-   to respond to in addition to any passwords he is required to provide
-   (this depends on how you set up user authentication for x11vnc).
-
-   If a second Web proxy is involved (i.e. the user's browser is inside
-   another firewall and policy requires using a Web proxy server) then
-   use this URL:
-   http://www.gateway.east:563/vnc/proxy/host2
-
-   This will involve downloading a signed java viewer applet jar file
-   that is able to interact with the internal proxy for the VNC
-   connection. See this FAQ for more info on how this works. Note:
-   sometimes with the Proxy case if you see 'Bad Gateway' error you will
-   have to wait 10 or so seconds and then hit reload. This seems to be
-   due to having to wait for a Connection Keepalive to terminate...
-
-   For completeness, the "trust" cases that skip a VNC certificate dialog
-   (discussed below) would be entered as:
-   http://www.gateway.east:563/vnc/trust/host2
-   http://www.gateway.east:563/vnc/trust/proxy/host2
-
-   You can of course choose shorter or more easy to remember URL formats.
-   Just change the Convenience RewriteRules in httpd.conf.
-
-     _________________________________________________________________
-
-   Port Variations:
-
-   Note that you can run this on the default HTTP port 80 instead of port
-   563. If you do not expect to have a browser connecting from inside a
-   proxying firewall (where sometimes only connections to ports 443 and
-   563 are allowed) this should be fine. Use "80" instead of "563" in the
-   httpd.conf config file (you may need to merge it with other default
-   port 80 things you have there).
-
-   Then the URL's will be a bit simpler:
-   http://www.gateway.east/vnc/host2
-   http://www.gateway.east/vnc/trust/host2
-
-   etc.
-
-   Besides 80 one could use any other random port number (since there are
-   so many port scans on 80, a little obscurity might be useful).
-
-   One option is to use port "443" (the default https:// port) instead of
-   "563". In this case Apache is not configured for mod_ssl; we just
-   happen to use port "443" in the way any random port would be used.
-   This could be handy if the Viewer side environment is restrictive in
-   that it only allows outgoing connections to ports 80 and 443 (and,
-   say, you didn't want to use port 80, or you wanted to use 80 for
-   something else). Another reason for using 443 would be some web proxy
-   environments only allow the CONNECT method to go to port 443 (and not
-   even the case 563 we use above).
-
-     _________________________________________________________________
-
-   Details:
-
-   Let's go through the httpd.conf additions in detail from the top.
-
-   The LoadModules directives load the necessary apache modules. Note
-   that mod_rewrite must be listed first. If you are compiling from
-   scratch something like this worked for us:
-  ./configure --enable-proxy=shared --enable-proxy-connect=shared --enable-ssl=
-shared --enable-rewrite=shared --prefix=/dist/apache
-
-   Then the VirtualHost *:563 virtual host section starts.
-
-   The "ProxyRequests On" and "AllowCONNECT 5915" enable the web server
-   to forward proxy requests to port 5915 (and only this port) INSIDE the
-   firewall. Think about the implications of this thoroughly and test it
-   carefully.
-
-   The RewriteRule's are for convenience only so that the URL entered
-   into the Web browser does not need the various extra parameters, e.g.:
-   http://www.gateway.east:563/vnc/host2/index.vnc?CONNECT=host2+5915&PORT=563,
-blah,blah...
-
-   (or otherwise make direct edits to index.vnc to set these parameters).
-   The forceProxy=yes parameter is passed to the applet to force the use
-   of a outgoing proxy socket connection. Use it only if the Web browser
-   is inside a separate Web proxying environment (i.e. large corporation)
-
-   The rewrites with parameter urlPrefix are described under Tricks for
-   Better Response. The "trust" ones (also described under Tricks) with
-   trustAllVncCerts tell the Java VNC applet to skip a dialog asking
-   about the VNC Certificate. They are a bit faster and more reliable
-   than the original method. In the best situation they lead to being
-   logged in 20 seconds or less (without them the time to login can be
-   much longer since a number of connections must timeout).
-
-   All of the x11vnc Java Viewer applet parameters are described in the
-   file classes/ssl/README
-
-   The external file /dist/apache/conf/vnc.hosts containing the allowed
-   VNC server hostnames is read in. Its 2nd column contains the VNC
-   display of the host (always 15 in our example; if you make it vary you
-   will need to adjust some lines in the httpd.conf accordingly, e.g.
-   AllowCONNECT). This list is used to constrain both the Jar file
-   download URL and the proxy CONNECT the VNC viewer makes to only the
-   intended VNC servers.
-
-   Limiting the proxy CONNECT is done with the two sets of RewriteCond
-   conditions.
-
-   Limiting the Jar file download URL is done in the remaining 4
-   RewriteRule's.
-
-   Note that these index.vnc and VncViewer.jar downloads to the browser
-   are not encrypted via SSL, and so in principle could be tampered with
-   by a really bad guy. The subsequent VNC connection, however, is
-   encrypted through a single SSL connection (it makes a CONNECT straight
-   to x11vnc). See below for how to have these initial downloads
-   encrypted as well (if the apache web server has SSL/mod_ssl, i.e.
-   https, enabled and configured).
-
-   Unfortunately the Java VNC viewer applet currently is not able to save
-   its own list of Certificates (e.g. the user says trust this VNC
-   certificate 'always'). This is because an applet it cannot open local
-   files, etc. Sadly, the applet cannot even remember certificates in the
-   same browser session because it is completely reinitialized for each
-   connection (see below).
-
-     _________________________________________________________________
-
-   Too Much?
-
-   If these apache rules are a little too much for you, there is a little
-   bit simpler scheme where you have to list each of the individual
-   machines in the httpd.conf and ssl.conf files. It may be a little more
-   typing to maintain, but perhaps being more straight forward (less
-   RewriteRule's) is desirable.
-
-     _________________________________________________________________
-
-   Problems?
-
-   To see example x11vnc output for a successful https://host:5900/
-   connection with the Java Applet see This Page.
-
-     _________________________________________________________________
-
-   Some Ideas for adding extra authentication, etc. for the paranoid:
-     * VNC passwords: -rfbauth, -passwdfile, or -usepw. Even adding a
-       simple company-wide VNC password helps block unwanted access.
-     * Unix passwords: -unixpw
-     * SSL Client certificates: -sslverify
-     * Apache AuthUserFile directive: .htaccess, etc.
-     * Filter connections based on IP address or hostname.
-     * Use Port-knocking on your firewall as described in: Enhanced
-       TightVNC Viewer (ssvnc).
-     * Add proxy password authentication (requires Viewer changes?)
-     * Run a separate instance of Apache that provides this VNC service
-       so it can be brought up and down independently of the normal web
-       server.
-     * How secure is the Client side? Public machines in internet cafes,
-       etc, are often hacked, with backdoors and VNC servers of their
-       own. Prefer using your own firewalled laptop to a public machine.
-
-
-     _________________________________________________________________
-
-   Using non-Java viewers with this scheme:
-
-   The ss_vncviewer stunnel wrapper script for VNC viewers has the -proxy
-   option that can take advantage of this method.
-   ss_vncviewer -proxy www.gateway.east:563   host1:15
-
-   For the case of the "double proxy" situation (see below) supply both
-   separated by a comma.
-   ss_vncviewer -proxy proxy1.foobar.com:8080,www.gateway.east:563   host1:15
-
-   For the Enhanced TightVNC Viewer (ssvnc) GUI (it uses ss_vncviewer on
-   Unix) put 'host1:15' into the 'VNC Server' entry box, and here are
-   possible Proxy/Gateway entries
-   Proxy/Gateway:   www.gateway.east:563
-   Proxy/Gateway:   proxy1.foobar.com:8080,www.gateway.east:563
-
-   then click on the 'Connect' button.
-
-     _________________________________________________________________
-
-   Downloading the Java applet to the browser via HTTPS:
-
-   To have the Java applet downloaded to the user's Web Browser via an
-   encrypted (and evidently safer) SSL connection the Apache webserver
-   should be configured for SSL via mod_ssl.
-
-   It is actually possible to use the x11vnc Key Management utility
-   "-sslGenCert" to generate your Apache/SSL .crt and .key files. (In
-   brief, run something like "x11vnc -sslGenCert server self:apache" then
-   copy the resulting self:apache.crt file to conf/ssl.crt/server.crt and
-   extract the private key part from self:apache.pem and paste it into
-   conf/ssl.key/server.key). Setting the env var REQ_ARGS='-days 1095'
-   before running x11vnc will bump up the expiration date (3 years in
-   this case).
-
-   Or you can use the standard methods described in the Apache mod_ssl
-   documentation to create your keys. Then restart Apache, usually
-   something like "apachectl stop" followed by "apachectl startssl"
-
-   In addition to the above sections in httpd.conf one should add the
-   following to ssl.conf:
-   SSLProxyEngine  On
-
-   RewriteEngine On

-
-   This is all in the "<VirtualHost _default_:443>" section of ssl.conf.
-
-   The user could then point the Web Browser to:
-   https://www.gateway.east/vnc/host2
-
-   or
-   https://www.gateway.east/vnc/proxy/host2
-
-   for the "double proxy" case. (Important: do not put a trailing "/" on
-   the URL, since that will defeat the RewriteRules.)
-
-   As with the httpd.conf case, the external file
-   (/dist/apache/conf/vnc.hosts in the above example) contains the
-   hostnames of the allowed VNC servers.
-
-   Note that inside the firewall the Java applet download traffic is not
-   encrypted (only over the Internet is SSL used) for these cases:
-   https://www.gateway.east/vnc/host2
-   https://www.gateway.east/vnc/proxy/host2
-
-   However for the special "vncs" rules above:
-   https://www.gateway.east/vncs/host2
-
-   the Java applet download is encrypted via SSL for both legs. Note that
-   the two legs are two separate SSL sessions. So the data is decrypted
-   inside an apache process and reencrypted by the apache process for the
-   2nd SSL session inside the same apache process (a very small gap one
-   might overlook).
-
-   The "vncs/trust" ones are like the "trust" ones described earlier
-   https://www.gateway.east/vncs/trust/mach2
-
-   and similarly for the httpsPort ones. See Tricks for Better Response.
-
-   In all of the above cases the VNC traffic from Viewer to x11vnc is
-   encrypted end-to-end in a single SSL session, even for the "double
-   proxy" case because the CONNECT method is used (there are actually two
-   CONNECT's for the "double proxy" case). This part (the VNC traffic) is
-   the most important part to have encrypted.
-
-   Note that the Certificate dialogs the user has in his web browser will
-   be for the Apache Certificate, while for the Java applet it will be
-   the x11vnc certificate.
-
-   Note also that you can have Apache serve up the Jar file VncViewer.jar
-   and/or index.vnc/proxy.vnc instead of each x11vnc if you want to.
-
-   The rules in ssl.conf are similar to the ones in httpd.conf and so are
-   not discussed in detail. The only really new thing is the /vncs
-   handling to download the applet jar via HTTPS on port 5915.
-
-   The special entries "/vnc443" are only used for the special helper
-   program (connect_switch) for the https port 443 only mode discussed
-   here.
-
-     _________________________________________________________________
-
-   INETD automation:
-
-   The "single-port" (i.e. 5915) HTTPS applet download and VNC connection
-   aspect shown here is convenient and also enables having x11vnc run out
-   of inetd. That way x11vnc is run on demand instead of being run all
-   the time (the user does not have to remember to start it). The first
-   connections to inetd download index.vnc and the Jar file (via https)
-   and the the last connection to inetd establishes the SSL VNC
-   connection. Since x11vnc is restarted for each connection, this will
-   be a bit slower than the normal process.
-
-   For example, the /etc/inetd.conf line could be:
-  5915 stream tcp nowait root /usr/sbin/tcpd /usr/local/bin/x11vnc_ssl.sh
-
-   where the script x11vnc_ssl.sh looks something like this:
-#!/bin/sh
-
-/usr/local/bin/x11vnc -inetd -oa /var/log/x11vnc-15.log \
-        -ssl SAVE -http -unixpw -localhost \
-        -display :0 -auth /home/THE_USER/.Xauthority
-
-   where, as usual, the inetd launching needs to know which user is
-   typically using the display on that machine. One could imagine giving
-   different users different ports, 5915, 5916, etc. to distinguish (then
-   the script would need to be passed the username). mod_rewrite could be
-   used to automatically map username in the URL to his port number.
-
-   A better way is to use the "-display WAIT:cmd=FINDDISPLAY" feature to
-   autodetect the user and Xauthority data:
-#!/bin/sh
-
-/usr/local/bin/x11vnc -inetd -oa /var/log/x11vnc-15.log \
-        -ssl SAVE -http -unixpw -localhost -users unixpw= \
-        -find
-
-   (we have used the alias -find for "-display WAIT:cmd=FINDDISPLAY".)
-   This way the user must supply his Unix username and password and then
-   his display and Xauthority data on that machine will be located and
-   returned to x11vnc to allow it to attach. If he doesn't have a display
-   running on that machine or he fails to log in correctly, the
-   connection will be dropped.
-
-   The variant "-display WAIT:cmd=FINDCREATEDISPLAY" (aliased by
-   "-create") will actually create a (virtual or real) X server session
-   for the user if one doesn't already exist. See here for details.
-
-   To enable inetd operation for the non-HTTPS Java viewer download (port
-   5815 in the above httpd.conf example) you will need to run x11vnc in
-   HTTPONCE mode on port 5815: For example, the /etc/inetd.conf line
-   could be:
-  5815 stream tcp nowait root /usr/sbin/tcpd /usr/local/bin/x11vnc \
-       -inetd -prog /usr/local/bin/x11vnc -oa /var/log/x11vnc-15.log \
-       -http_ssl -display WAIT:cmd=HTTPONCE
-
-   where the long inetd.conf line has been split. Note how the -http_ssl
-   tries to automatically find the .../classes/ssl subdirectory. This
-   requires the -prog option available in x11vnc 0.8.4 (a shell script
-   wrapper, e.g. /usr/local/bin/x11vnc_http.sh can be used to work around
-   this).
-
-   Also note the use of "-ssl SAVE" above. This way a saved server.pem is
-   used for each inetd invocation (rather generating a new one each time
-   as happens for "-ssl TMP"). Note that it cannot have a protecting
-   passphrase because inetd will not be able to supply it.
-
-   Another option is:
-  5815 stream tcp nowait root /usr/sbin/tcpd /usr/local/bin/x11vnc \
-       -inetd -httpdir /usr/local/share/x11vnc/classes/ssl \
-       -oa /var/log/x11vnc-15.log -display WAIT:cmd=HTTPONCE
-
-   (this also requires a feature found in x11vnc 0.8.4).

-
-   Other Ideas:
-
-   - The above schemes work, but they are a bit complicated with all of
-   the rigging. There should be more elegant ways to configure Apache to
-   do these, but we have not found them (please let us know if you
-   discover something nice). However, once this scheme has been set up
-   and is working it is easy to maintain and add/delete workstations,
-   etc.
-
-   - In general Apache is not required, but it makes things convenient.
-   The firewall itself could do the port redirection via its firewall
-   rules. Evidently different Internet-facing ports would be required for
-   each workstation. This could be set up using iptables rules for
-   example. If there were just one or two machines this would be the
-   easiest method. For example:
-  iptables -t nat -A PREROUTING -p tcp -d 24.35.46.57 --dport 5901 -j DNAT --to
--destination 192.168.1.2:5915
-  iptables -t nat -A PREROUTING -p tcp -d 24.35.46.57 --dport 5902 -j DNAT --to
--destination 192.168.1.3:5915
-
-   Where 24.35.46.57 is the internet IP address of the gateway. In this
-   example 24.35.46.57:5901 is redirected to the internal machine
-   192.168.1.2:5915 and 24.35.46.57:5902 is redirected to another
-   internal machine 192.168.1.3:5915, both running x11vnc -ssl ... in SSL
-   mode. For this example, the user would point the web browser to, e.g.:
-  https://24.35.46.57:5901/?PORT=5901
-
-   or using the stunnel wrapper script:
-  ss_vncviewer 24.35.46.57:1
-
-   One can achieve similar things with dedicated firewall/routers (e.g.
-   Linksys) using the device's web or other interface to configure the
-   firewall.
-
-   If the user may be coming out of a firewall using a proxy it may be
-   better to redirect ports 443 and 563 (instead of 5901 and 5902) to the
-   internal machines so that the user's proxy will allow CONNECTing to
-   them.
-
-   - The redirection could also be done at the application level using a
-   TCP redirect program (e.g. ip_relay or fancier ones). Evidently more
-   careful internal hostname checking, etc., could be performed by the
-   special purpose application to add security. See connect_switch which
-   is somewhat related.
-
-   - One might imagine the ProxyPass could be done for the VNC traffic as
-   well (for the ssl.conf case) to avoid the CONNECT proxying completely
-   (which would be nice to avoid). Unfortunately we were not able to get
-   this to work. Since HTTP is a request-response protocol (as opposed to
-   a full bidirectional link required by VNC that CONNECT provides) this
-   makes it difficult to do. It may be possible, but we haven't found out
-   how yet.
-
-   All of the x11vnc Java Viewer applet parameters are described in the
-   file classes/ssl/README
-
-     _________________________________________________________________
-
-   Tricks for Better Response and reliability:
-
-   The "original scheme" using httpd.conf and ssl.conf rewrites without
-   urlPrefix and trustAllVncCerts above should work OK, but may lead to
-   slow and/or unreliable loading of the applet and final connection to
-   x11vnc. The following are what I do now to get better response and
-   reliability. YMMV.
-
-   The problem with the "original scheme" is that there is a point where
-   the VNC Viewer applet can try up to 3 times to retrieve the x11vnc
-   certificate, since it needs to get it to show it to you and ask you if
-   you accept it. This can add about 45 seconds to the whole process
-   (which takes 1 to 1.5 minutes with all the dialogs) since a couple of
-   those connections must time out. The "trust" items in the config add a
-   parameter trustAllVncCerts=yes similar to the forceProxy=yes
-   parameter. This can cut the total time to the VNC password prompt down
-   to 15 seconds which is pretty good. (Note by ignoring the certificate
-   this does not protect against man-in-the-middle attacks which are
-   rare, but maybe the won't be so rare in the future... see
-   dsniff/webmitm and cain)
-
-   First make sure the x11vnc SSL certificate+key is the same as
-   Apache's. (otherwise you may get one extra dialog and/or one extra
-   connection that has to time out).
-
-   The following RewriteRule's are the same now advocated in the
-   instructions above.
-
-   The httpsPort and urlPrefix= parameters give hints to the applet to
-   improve connecting: This is what goes in httpd.conf:
-   RewriteEngine On
-   RewriteRule /vnc/([^/]+)$               /vnc/$1/index.vnc?CONNECT=$1+5915&PO
-RT=563&urlPrefix=_2F_vnc_2F_$1 [R,NE]
-   RewriteRule /vnc/trust/([^/]+)$         /vnc/$1/index.vnc?CONNECT=$1+5915&PO
-RT=563&urlPrefix=_2F_vnc_2F_$1&trustAllVncCerts=yes [R,NE]
-   RewriteRule /vnc/proxy/([^/]+)$         /vnc/$1/proxy.vnc?CONNECT=$1+5915&PO
-RT=563&urlPrefix=_2F_vnc_2F_$1&forceProxy=yes [R,NE]
-   RewriteRule /vnc/trust/proxy/([^/]+)$   /vnc/$1/proxy.vnc?CONNECT=$1+5915&PO
-RT=563&urlPrefix=_2F_vnc_2F_$1&forceProxy=yes&trustAllVncCerts=yes [R,NE]
-
-   The httpsPort and urlPrefix provide useful hints to the VNC Viewer
-   applet when it connects to x11vnc to glean information about Proxies,
-   certificates, etc.
-
-   This is what goes into ssl.conf:
-   RewriteEngine On
-   RewriteRule /vnc/([^/]+)$                /vnc/$1/index.vnc?CONNECT=$1+5915&P
-ORT=563&httpsPort=443&GET=1&urlPrefix=_2F_vnc_2F_$1 [R,NE]
-   RewriteRule /vnc/proxy/([^/]+)$          /vnc/$1/proxy.vnc?CONNECT=$1+5915&P
-ORT=563&httpsPort=443&GET=1&urlPrefix=_2F_vnc_2F_$1&forceProxy=yes [R,NE]
-   RewriteRule /vncs/([^/]+)$              /vncs/$1/index.vnc?CONNECT=$1+5915&P
-ORT=563&httpsPort=443&GET=1&urlPrefix=_2F_vncs_2F_$1 [R,NE]
-   RewriteRule /vncs/proxy/([^/]+)$        /vncs/$1/proxy.vnc?CONNECT=$1+5915&P
-ORT=563&httpsPort=443&GET=1&urlPrefix=_2F_vncs_2F_$1&forceProxy=yes [R,NE]
-   RewriteRule /vncs/trust/([^/]+)$        /vncs/$1/index.vnc?CONNECT=$1+5915&P
-ORT=563&httpsPort=443&GET=1&urlPrefix=_2F_vncs_2F_$1&trustAllVncCerts=yes [R,NE
-]
-   RewriteRule /vncs/trust/proxy/([^/]+)$  /vncs/$1/proxy.vnc?CONNECT=$1+5915&P
-ORT=563&httpsPort=443&GET=1&urlPrefix=_2F_vncs_2F_$1&forceProxy=yes&trustAllVnc
-Certs=yes [R,NE]
-
-   The rest is the same.
-
-   The httpsPort and urlPrefix and GET provide useful hints to the VNC
-   Viewer applet when it connects to x11vnc to glean information about
-   Proxies, certificates, etc, and also for the ultimate VNC connection
-   (GET speeds this up by sending a special HTTP GET to cause x11vnc to
-   immediately switch to the VNC protocol).
-
-   To turn these into URLs, as was done above, take the string in the
-   RewriteRule, e.g. /vncs and turn it into
-   https://gateway/vncs/machinename Similarly for non-https:
-   http://gateway:563/vnc/machinename
-
-   If you use the 'trust' ones, you are performing NO checks, visual or
-   otherwise, on the VNC SSL certificate. It is trusted without question.
-   This speeds things up because it avoids a dialog about certificates,
-   but of course has some risk WRT Man in the Middle attacks. I don't
-   recommend them. It is better to use /vnc or /vncs and the first time
-   you connect carefully check the Certificate and then tell your Browser
-   and Java Virtual Machine to trust the certificate 'Always'. Then if
-   you later get an unexpected dialog, you know something is wrong.
-   Nearly always it is just a changed or expired certificate, but better
-   safe than sorry...

-Enhanced TightVNC Viewer   (SSVNC:   SSL/SSH VNC viewer)
-
-   (To Downloads)  (To Quick Start)
-
-   [ssvnc.gif] [ssvnc_windows.gif] [ssvnc_macosx.gif] . .
-
-
-   The Enhanced TightVNC Viewer, SSVNC, adds encryption security to VNC
-   connections.
-
-   The package provides a GUI for Windows, Mac OS X, and Unix that
-   automatically starts up an STUNNEL SSL tunnel for SSL or ssh/plink for
-   SSH connections to any VNC server, such as x11vnc, and then launches
-   the VNC Viewer to use the encrypted tunnel.
-
-   The x11vnc server has built-in SSL support, however SSVNC can make SSL
-   encrypted VNC connections to any VNC Server if they are running an SSL
-   tunnel, such as STUNNEL or socat, at their end. SSVNC's SSH tunnel
-   will work to any VNC Server host running sshd that you can log into.
-
-   The Enhanced TightVNC Viewer package started as a project to add some
-   patches to the long neglected Unix TightVNC Viewer. However, now the
-   front-end GUI, encryption, and wrapper scripts features possibly
-   outweigh the Unix TightVNC Viewer improvements (see the lists below to
-   compare).
-
-   The SSVNC Unix vncviewer can also be run without the SSVNC encryption
-   GUI as an enhanced replacement for the xvncviewer, xtightvncviewer,
-   etc., viewers.
-
-   In addition to normal SSL, SSVNC also supports the VeNCrypt SSL/TLS
-   and Vino/ANONTLS encryption extensions to VNC on Unix, Mac OS X, and
-   Windows. Via the provided SSVNC VeNCrypt bridge, VeNCrypt and ANONTLS
-   encryption also works with any third party VNC Viewer (e.g. RealVNC,
-   TightVNC, UltraVNC, etc...) you select via 'Change VNC Viewer'.
-
-   The short name for this project is "ssvnc" for SSL/SSH VNC Viewer.
-   This is the name of the command to start it.
-
-   There is a simplified SSH-Only mode (sshvnc). And an even more
-   simplified Terminal-Services mode (tsvnc) for use with x11vnc on the
-   remote side.
-
-   The tool has many additional features; see the descriptions below.
-
-   It is a self-contained bundle, you could carry it around on, say, a
-   USB memory stick / flash drive for secure VNC viewing from almost any
-   machine, Unix, Mac OS X, and Windows (and if you create a directory
-   named "Home" in the toplevel ssvnc directory on the drive your VNC
-   profiles and certs will be kept there as well). For Unix, there is
-   also a conventional source tarball to build and install in the normal
-   way and not use a pre-built bundle.
-
-     _________________________________________________________________
-
-    Announcements:
-
-   Important: If you created any SSL certificates with SSVNC (or anything
-   else) on a Debian or Ubuntu system from Sept. 2006 through May 2008,
-   then those keys are likely extremely weak and can be easily cracked.
-   The certificate files should be deleted and recreated on a non-Debian
-   system or an updated one. See
-   http://www.debian.org/security/2008/dsa-1571 for details. The same
-   applies to SSH keys.
-
-   Please read this information on using SSVNC on workstations with
-   Untrusted Local Users.
-
-     _________________________________________________________________
-
-    Feature List:
-
-   Wrapper scripts and a tcl/tk GUI were written to create these features
-   for Unix, Mac OS X, and Windows:
-     * SSL support for connections using the bundled stunnel program.
-     * Automatic SSH connections from the GUI (system ssh is used on Unix
-       and MacOS X; bundled plink is used on Windows)
-     * Ability to Save and Load VNC profiles for different hosts.
-     * You can also use your own VNC Viewer, e.g. UltraVNC or RealVNC,
-       with the SSVNC encryption GUI front-end if you prefer.
-     * Create or Import SSL Certificates and Private Keys.
-     * Reverse (viewer listening) VNC connections via SSL and SSH.
-     * VeNCrypt SSL/TLS VNC encryption support (used by VeNCrypt, QEMU,
-       ggi, libvirt/virt-manager/xen, vinagre/gvncviewer/gtk-vnc)
-     * ANONTLS SSL/TLS VNC encryption support (used by Vino)
-     * VeNCrypt and ANONTLS are also enabled for any 3rd party VNC Viewer
-       (e.g. RealVNC, TightVNC, UltraVNC ...) on Unix, MacOSX, and
-       Windows via the provided SSVNC VeNCrypt Viewer Bridge tool (use
-       'Change VNC Viewer' to select the one you want.)
-     * Support for Web Proxies, SOCKS Proxies, and the UltraVNC repeater
-       proxy (e.g. repeater://host:port+ID:1234). Multiple proxies may be
-       chained together (3 max).
-     * Support for SSH Gateway connections and non-standard SSH ports.
-     * Automatic Service tunnelling via SSH for CUPS and SMB Printing,
-       ESD/ARTSD Audio, and SMB (Windows/Samba) filesystem mounting.
-     * Sets up any additional SSH port redirections that you want.
-     * Zeroconf (aka Bonjour) is used on Unix and Mac OS X to find VNC
-       servers on your local network if the avahi-browse or dns-sd
-       program is available and in your PATH.
-     * Port Knocking for "closed port" SSH/SSL connections. In addition
-       to a simple fixed port sequence and one-time-pad implementation, a
-       hook is also provided to run any port knocking client before
-       connecting.
-     * Support for native MacOS X usage with bundled Chicken of the VNC
-       viewer (the Unix X11 viewer is also provided for MacOS X, and is
-       better IMHO. It is now the default on MacOS X.)
-     * Dynamic VNC Server Port determination and redirection (using ssh's
-       builtin SOCKS proxy, ssh -D) for servers like x11vnc that print
-       out PORT= at startup.
-     * Unix Username and Password entry for use with "x11vnc -unixpw"
-       type login dialogs.
-     * Simplified mode launched by command "sshvnc" that is SSH Only.
-     * Simplified mode launched by command "tsvnc" that provides a VNC
-       "Terminal Services" mode (uses x11vnc on the remote side).
-     * IPv6 support for all connection modes on Unix, MacOSX, and
-       Windows.
-
-   Patches to TightVNC 1.3.9 vnc_unixsrc tree were created for Unix
-   TightVNC Viewer improvements (these only apply to the Unix VNC viewer,
-   including MacOSX XQuartz):
-     * rfbNewFBSize VNC support (dynamic screen resizing)
-     * Client-side Scaling of the Desktop in the viewer.
-     * ZRLE VNC encoding support (RealVNC's encoding)
-     * Support for the ZYWRLE encoding, a wavelet based extension to ZRLE
-       to improve compression of motion video and photo regions.
-     * TurboVNC support (VirtualGL's modified TightVNC encoding; requires
-       TurboJPEG library)
-     * Pipelined Updates of the framebuffer as in TurboVNC (asks for the
-       next update before the current one has finished downloading; this
-       gives some speedup on high latency connections.)
-     * Cursor alphablending with x11vnc at 32bpp (-alpha option)
-     * Option "-unixpw ..." for use with "x11vnc -unixpw" type login
-       dialogs.
-     * Support for UltraVNC extensions: 1/n Server side scaling, Text
-       Chat, Single Window, Disable Server-side Input. Both UltraVNC and
-       x11vnc servers support these extensions.
-     * UltraVNC File Transfer via an auxiliary Java helper program (java
-       must be in $PATH). Note that the x11vnc server also supports
-       UltraVNC file transfer.
-     * Connection support for the UltraVNC repeater proxy (-repeater
-       option).
-     * Support for UltraVNC Single Click operation. (both unencrypted: SC
-       I, and SSL encrypted: SC III)
-     * Support for UltraVNC DSM Encryption Plugin symmetric encryption
-       mode. (ARC4, AESV2, MSRC4, and SecureVNC)
-     * Support for UltraVNC MS-Logon authentication (NOTE: the UltraVNC
-       MS-Logon key exchange implementation is very weak; an eavesdropper
-       on the network can recover your Windows password easily in a few
-       seconds; you need to use an additional encrypted tunnel with
-       MS-Logon.)
-     * Support for symmetric encryption (including blowfish and 3des
-       ciphers) to Non-UltraVNC Servers. Any server using the same
-       encryption method will work, e.g.:  x11vnc -enc blowfish:./my.key
-     * Instead of hostname:display one can also supply "exec=command
-       args..." to connect the viewer to the stdio of an external command
-       (e.g. stunnel or socat) rather than using a TCP/IP socket. Unix
-       domain sockets, e.g. /path/to/unix/socket, and a previously opened
-       file descriptor fd=0, work too.
-     * Local Port Protections for STUNNEL and SSH: avoid having for long
-       periods of time a listening port on the the local (VNC viewer)
-       side that redirects to the remote side.
-     * Reverse (viewer listening) VNC connections can show a Popup dialog
-       asking whether to accept the connection or not (-acceptpopup.) The
-       extra info provided by UltraVNC Single Click reverse connections
-       is also supported (-acceptpopupsc)
-     * Extremely low color modes: 64 and 8 colors in 8bpp
-       (-use64/-bgr222, -use8/-bgr111)
-     * Medium color mode: 16bpp mode on a 32bpp Viewer display
-       (-16bpp/-bgr565)
-     * For use with x11vnc's client-side caching -ncache method use the
-       cropping option -ycrop n. This will "hide" the large pixel buffer
-       cache below the actual display. Set to the actual height or use -1
-       for autodetection (also, tall screens, H > 2*W, are autodetected
-       by default).
-     * Escape Keys: specify a set of modifier keys so that when they are
-       all pressed down you can invoke Popup menu actions via keystrokes.
-       I.e., a set of 'Hot Keys'. One can also pan (move) the desktop
-       inside the viewport via Arrow keys or a mouse drag.
-     * Scrollbar width setting: -sbwidth n, the default is very thin, 2
-       pixels, for less distracting -ycrop usage.
-     * Selection text sending and receiving can be fine-tuned with the
-       -sendclipboard, -sendalways, and -recvtext options.
-     * TightVNC compression and quality levels are automatically set
-       based on observed network latency (n.b. not bandwidth.)
-     * Improvements to the Popup menu, all of these can now be changed
-       dynamically via the menu: ViewOnly, Toggle Bell, CursorShape
-       updates, X11 Cursor, Cursor Alphablending, Toggle Tight/ZRLE,
-       Toggle JPEG, FullColor/16bpp/8bpp (256/64/8 colors), Greyscale for
-       low color modes, Scaling the Viewer resolution, Escape Keys,
-       Pipeline Updates, and others, including UltraVNC extensions.
-     * Maintains its own BackingStore if the X server does not.
-     * The default for localhost:0 connections is not raw encoding since
-       same-machine connections are pretty rare. Default assumes you are
-       using a SSL or SSH tunnel. Use -rawlocal to revert.
-     * XGrabServer support for fullscreen mode, for old window managers
-       (-grab/-graball option).
-     * Fix for Popup menu positioning for old window managers (-popupfix
-       option).
-     * The VNC Viewer ssvncviewer supports IPv6 natively (no helpers
-       needed.)
-
-   The list of 3rd party software bundled in the archive files:
-     * TightVNC Viewer  (windows, unix, macosx)
-     * Chicken of the VNC Viewer  (macosx)
-     * Stunnel  (windows, unix, macosx)
-     * Putty/Plink/Pageant  (windows)
-     * OpenSSL  (windows)
-     * esound  (windows)
-
-   These are all self-contained in the bundle directory: they will not be
-   installed on your system. Just un-zip or un-tar the file you
-   downloaded and run the frontend ssvnc straight from its directory.
-   Alternatively, on Unix you can use the conventional source tarball.
-
-     _________________________________________________________________
-
-   Here is the Quick Start info from the README for how to setup and use
-   SSVNC:
-Quick Start:
------------
-
-Unix and Mac OS X:
-
-    Inside a Terminal do something like the following.
-
-    Unpack the archive:
-
-        % gzip -dc ssvnc-1.0.29.tar.gz | tar xvf -
-
-    Run the GUI:
-
-        % ./ssvnc/Unix/ssvnc               (for Unix)
-
-        % ./ssvnc/MacOSX/ssvnc             (for Mac OS X)
-
-    The smaller file "ssvnc_no_windows-1.0.29.tar.gz"
-    could have been used as well.
-
-    On MacOSX you could also click on the SSVNC app icon in the Finder.
-
-    On MacOSX if you don't like the Chicken of the VNC (e.g. no local
-    cursors, no screen size rescaling, and no password prompting), and you
-    have the XDarwin X server installed, you can set DISPLAY before starting
-    ssvnc (or type DISPLAY=... in Host:Disp and hit Return).  Then our
-    enhanced TightVNC viewer will be used instead of COTVNC.
-    Update: there is now a 'Use X11 vncviewer on MacOSX' under Options ...
-
-
-    If you want a SSH-only tool (without the distractions of SSL) run
-    the command:
-
-                sshvnc
-
-    instead of "ssvnc".  Or click "SSH-Only Mode" under Options.
-    Control-h will toggle between the two modes.
-
-
-    If you want a simple VNC Terminal Services only mode (requires x11vnc
-    on the remote server) run the command:
-
-                tsvnc
-
-    instead of "ssvnc".  Or click "Terminal Services" under Options.
-    Control-t will toggle between the two modes.
-
-    "tsvnc profile-name" and "tsvnc user@hostname" work too.
-
-
-Unix/MacOSX Install:
-
-    There is no standard install for the bundles, but you can make
-    symlinks like so:
-
-        cd /a/directory/in/PATH
-        ln -s /path/to/ssvnc/bin/{s,t}* .
-
-    Or put /path/to/ssvnc/bin, /path/to/ssvnc/Unix, or /path/to/ssvnc/MacOSX
-    in your PATH.
-
-    For the conventional source tarball it will compile and install, e.g.:
-
-       gzip -dc ssvnc-1.0.29.src.tar.gz | tar xvf -
-       cd ssvnc-1.0.29
-       make config
-       make all
-       make PREFIX=/my/install/dir install
-
-    then have /my/install/dir/bin in your PATH.
-
-
-
-Windows:
-
-    Unzip, using WinZip or a similar utility, the zip file:
-
-        ssvnc-1.0.29.zip
-
-    Run the GUI, e.g.:
-
-        Start -> Run -> Browse
-
-    and then navigate to
-
-        .../ssvnc/Windows/ssvnc.exe
-
-    select Open, and then OK to launch it.
-
-    The smaller file "ssvnc_windows_only-1.0.29.zip"
-    could have been used as well.
-
-    You can make a Windows shortcut to this program if you want to.
-
-    See the Windows/README.txt for more info.
-
-
-    If you want a SSH-only tool (without the distractions of SSL) run
-    the command:
-
-                sshvnc.bat
-
-    Or click "SSH-Only Mode" under Options.
-
-
-    If you want a simple VNC Terminal Services only mode (requires x11vnc
-    on the remote server) run the command:
-
-                tsvnc.bat
-
-    Or click "Terminal Services" under Options.  Control-t will toggle
-    between the two modes.  "tsvnc profile-name" and "tsvnc user@hostname"
-    work too.

-
-   The bundle unpacks a directory/folder named: ssvnc. It contains these
-   programs to launch the GUI:
-        Windows/ssvnc.exe        for Windows
-        MacOSX/ssvnc             for Mac OS X
-        Unix/ssvnc               for Unix
-
-   (the Mac OS X and Unix launchers are simply links to the bin
-   directory). See the README for more information.
-
-   The SSH-Only mode launcher program has name sshvnc. The Terminal
-   Services mode launcher program (assumes x11vnc 0.8.4 or later and Xvfb
-   installed on the server machine) has name tsvnc.
-
-   The Viewer SSL support is done via a wrapper script (bin/ssvnc_cmd
-   that calls bin/util/ss_vncviewer) that starts up the STUNNEL tunnel
-   first and then starts the TightVNC viewer pointed at that tunnel. The
-   bin/ssvnc program is a GUI front-end to that script. See this FAQ for
-   more details on SSL tunnelling. In SSH connection mode, the wrappers
-   start up SSH appropriately.
-
-
-   Memory Stick Usage: If you create a directory named "Home" in that
-   toplevel ssvnc directory then that will be used as the base for
-   storing VNC profiles and certificates. Also, for convenience, if you
-   first run the command with "." as an argument (e.g. "ssvnc .") it will
-   automatically create the "Home" directory for you. This is handy if
-   you want to place SSVNC on a USB flash drive that you carry around for
-   mobile use and you want the profiles you create to stay with the drive
-   (otherwise you'd have to browse to the drive directory each time you
-   load or save).
-
-   One user on Windows created a BAT file to launch SSVNC and needed to
-   do this to get the Home directory correct:
-cd \ssvnc\Windows
-start \ssvnc\Windows\ssvnc.exe
-
-   (an optional profile name can be supplied to the ssvnc.exe line)
-
-   WARNING: if you use ssvnc from an "Internet Cafe", i.e. some untrusted
-   computer, please be aware that someone may have set up that machine to
-   be capturing your keystrokes, etc.
-
-
-   SSH-Only version: The command "sshvnc" can be run instead of "ssvnc"
-   to get an SSH-only version of the tool:
-
-   [sshvnc.gif]
-
-   These also work: "sshvnc myprofile" and "sshvnc user@hostname". To
-   switch from the regular SSVNC mode, click "SSH-Only Mode" under
-   Options. This mode is less distracting if you never plan to use SSL,
-   manage certificates, etc.
-
-
-   Terminal Services Only: The command "tsvnc" can be run instead of
-   "ssvnc" to get a "Terminal Services" only version of the tool:
-
-   [tsvnc.gif]
-
-   These also work: "tsvnc myprofile" and "tsvnc user@hostname". To
-   switch from the regular SSVNC mode, click "Terminal Services" under
-   Options.
-
-   This mode requires x11vnc (0.9.3 or later) installed on the remote
-   machine to find, create, and manage the user sessions. SSH is used to
-   create the encrypted and authenticated tunnel. The Xvfb (virtual
-   framebuffer X server) program must also be installed on the remote
-   system. However tsvnc will also connect to a real X session (i.e. on
-   the physical hardware) if you are already logged into the X session;
-   this is a useful access mode and does not require Xvfb on the remote
-   system.
-
-   This mode should be very easy for beginner users to understand and
-   use. On the remote end you only need to have x11vnc and Xvfb available
-   in $PATH, and on the local end you just run something like:
-   tsvnc myname@myhost.com
-
-   (or start up the tsvnc GUI first and then enter myname@myhost.com and
-   press "Connect").
-
-   Normally the Terminal Services sessions created are virtual (RAM-only)
-   ones (e.g. Xvfb, Xdummy, or Xvnc), however a nice feature is if you
-   have a regular X session (i.e displaying on the physical hardware) on
-   the remote machine that you are ALREADY logged into, then the x11vnc
-   run from tsvnc will find it for you as well.
-
-   Also, there is setting "X Login" under Advanced Options that allows
-   you to attach to a real X server with no one logged in yet (i.e.
-   XDM/GDM/KDM Login Greeter screen) as long as you have sudo(1)
-   permission on the remote machine.
-
-   Nice features to soon to be added to the tsvnc mode are easy CUPS
-   printing (working fairly well) and Sound redirection (needs much work)
-   of the Terminal Services Desktop session. It is easier in tsvnc mode
-   because the entire desktop session can be started with the correct
-   environment. ssvnc tries to handle the general case of an already
-   started desktop and that is more difficult.
-
-
-   Proxies: Web proxies, SOCKS proxies, and the UltraVNC repeater proxy
-   are supported to allow the SSVNC connection to go through the proxy to
-   the otherwise unreachable VNC Server. SSH gateway machines can be used
-   in the same way. Read more about SSVNC proxy support here.
-
-
-   Dynamic VNC Server Port determination: If you are running SSVNC on
-   Unix and are using SSH to start the remote VNC server and the VNC
-   server prints out the line "PORT=NNNN" to indicate which dynamic port
-   it is using (x11vnc does this), then if you prefix the SSH command
-   with "PORT=" SSVNC will watch for the PORT=NNNN line and uses ssh's
-   built in SOCKS proxy (ssh -D ...) to connect to the dynamic VNC server
-   port through the SSH tunnel. For example:
-        VNC Host:Display     user@somehost.com
-        Remote SSH Command:  PORT= x11vnc -find
-
-   or "PORT= x11vnc -display :0 -localhost", etc. Or use "P= x11vnc ..."
-
-   There is also code to detect the display of the regular Unix
-   vncserver(1). It extracts the display (and hence port) from the lines
-   "New 'X' desktop is hostname:4" and also "VNC server is already
-   running as :4". So you can use something like:
-        PORT= vncserver; sleep 15
-or:     PORT= vncserver :4; sleep 15
-
-   the latter is preferred because when you reconnect with it will find
-   the already running one. The former one will keep creating new X
-   sessions if called repeatedly.
-
-   If you use PORT= on Windows, a large random port is selected instead
-   and the -rfbport option is passed to x11vnc (it does not work with
-   vncserver).
-
-
-
-   Patches for Unix Tightvnc viewer:
-
-   The rfbNewFBSize support allows the enhanced TightVNC Unix viewer to
-   resize when the server does (e.g. "x11vnc -R scale=3/4" remote control
-   command).
-
-   The cursor alphablending is described here.
-
-   The RealVNC ZRLE encoding is supported, in addition to some low colors
-   modes (16bpp and 8bpp at 256, 64, and even 8 colors, for use on very
-   slow connections). Greyscales are also enabled for the low color
-   modes.
-
-   The Popup menu (F8) is enhanced with the ability to change many things
-   on the fly. F9 is added as a shortcut to toggle FullScreen mode.
-
-   Client Side Caching: The x11vnc client-side caching is handled nicely
-   by this viewer. The very large pixel cache below the actual display in
-   this caching method is distracting. Our Unix VNC viewer will
-   automatically try to autodetect the actual display height if the
-   framebuffer is very tall (more than twice as high as it is wide). One
-   can also set the height to the known value via -ycrop n, or use -ycrop
-   -1 to force autodection. In fullscreen mode one is not possible to
-   scroll down to the pixel cache region. In non-fullscreen mode the
-   window manager frame is "shrink-wrapped" around the actual screen
-   display. You can still scroll down to the pixel cache region. The
-   scrollbars are set to be very thin (2 pixels) to be less distracting.
-   Use the -sbwidth n to make them wider.
-
-   Probably nobody is interested in the grabserver patch for old window
-   managers when the viewer is in fullscreen mode... This and some other
-   unfixed bugs have been fixed in our patches (fullscreen toggle works
-   with KDE, -x11cursor has been fixed, and the dot cursor has been made
-   smaller).

-
-Enhanced TightVNC viewer (SSVNC) options:
-
-   URL http://www.karlrunge.com/x11vnc/ssvnc.html
-
-   Note: ZRLE and ZYWRLE encodings are now supported.
-
-   Note: F9 is shortcut to Toggle FullScreen mode.
-
-   Note: In -listen mode set the env var. SSVNC_MULTIPLE_LISTEN=1
-         to allow more than one incoming VNC server at a time.
-         This is the same as -multilisten described below.  Set
-         SSVNC_MULTIPLE_LISTEN=MAX:n to allow no more than "n"
-         simultaneous reverse connections.
-
-   Note: If the host:port is specified as "exec=command args..."
-         then instead of making a TCP/IP socket connection to the
-         remote VNC server, "command args..." is executed and the
-         viewer is attached to its stdio.  This enables tunnelling
-         established via an external command, e.g. an stunnel(8)
-         that does not involve a listening socket.  This mode does
-         not work for -listen reverse connections.
-
-         If the host:port is specified as "fd=n" then it is assumed
-         n is an already opened file descriptor to the socket. (i.e
-         the parent did fork+exec)
-
-         If the host:port contains a '/' it is interpreted as a
-         unix-domain socket (AF_LOCAL insead of AF_INET)
-
-        -multilisten  As in -listen (reverse connection listening) except
-                    allow more than one incoming VNC server to be connected
-                    at a time.  The default for -listen of only one at a
-                    time tries to play it safe by not allowing anyone on
-                    the network to put (many) desktops on your screen over
-                    a long window of time. Use -multilisten for no limit.
-
-        -acceptpopup  In -listen (reverse connection listening) mode when
-                    a reverse VNC connection comes in show a popup asking
-                    whether to Accept or Reject the connection.  The IP
-                    address of the connecting host is shown.  Same as
-                    setting the env. var. SSVNC_ACCEPT_POPUP=1.
-
-        -acceptpopupsc  As in -acceptpopup except assume UltraVNC Single
-                    Click (SC) server.  Retrieve User and ComputerName
-                    info from UltraVNC Server and display in the Popup.
-
-        -use64      In -bgr233 mode, use 64 colors instead of 256.
-        -bgr222     Same as -use64.
-
-        -use8       In -bgr233 mode, use 8 colors instead of 256.
-        -bgr111     Same as -use8.
-
-        -16bpp      If the vnc viewer X display is depth 24 at 32bpp
-                    request a 16bpp format from the VNC server to cut
-                    network traffic by up to 2X, then tranlate the
-                    pixels to 32bpp locally.
-        -bgr565     Same as -16bpp.
-
-        -grey       Use a grey scale for the 16- and 8-bpp modes.
-
-        -alpha      Use alphablending transparency for local cursors
-                    requires: x11vnc server, both client and server
-                    must be 32bpp and same endianness.
-
-        -scale str  Scale the desktop locally.  The string "str" can
-                    a floating point ratio, e.g. "0.9", or a fraction,
-                    e.g. "3/4", or WxH, e.g. 1280x1024.  Use "fit"
-                    to fit in the current screen size.  Use "auto" to
-                    fit in the window size.  "str" can also be set by
-                    the env. var. SSVNC_SCALE.
-
-                    If you observe mouse trail painting errors, enable
-                    X11 Cursor mode (either via Popup or -x11cursor.)
-
-                    Note that scaling is done in software and so can be
-                    slow and requires more memory.  Some speedup Tips:
-
-                        ZRLE is faster than Tight in this mode.  When
-                        scaling is first detected, the encoding will
-                        be automatically switched to ZRLE.  Use the
-                        Popup menu if you want to go back to Tight.
-                        Set SSVNC_PRESERVE_ENCODING=1 to disable this.
-
-                        Use a solid background on the remote side.
-                        (e.g. manually or via x11vnc -solid ...)
-
-                        If the remote server is x11vnc, try client
-                        side caching: x11vnc -ncache 10 ...
-
-        -ycrop n    Only show the top n rows of the framebuffer.  For
-                    use with x11vnc -ncache client caching option
-                    to help "hide" the pixel cache region.
-                    Use a negative value (e.g. -1) for autodetection.
-                    Autodetection will always take place if the remote
-                    fb height is more than 2 times the width.
-
-        -sbwidth n  Scrollbar width for x11vnc -ncache mode (-ycrop),
-                    default is very narrow: 2 pixels, it is narrow to
-                    avoid distraction in -ycrop mode.
-
-        -nobell     Disable bell.
-
-        -rawlocal   Prefer raw encoding for localhost, default is
-                    no, i.e. assumes you have a SSH tunnel instead.
-
-        -notty      Try to avoid using the terminal for interactive
-                    responses: use windows for messages and prompting
-                    instead.  Messages will also be printed to terminal.
-
-        -sendclipboard  Send the X CLIPBOARD selection (i.e. Ctrl+C,
-                        Ctrl+V) instead of the X PRIMARY selection (mouse
-                        select and middle button paste.)
-
-        -sendalways     Whenever the mouse enters the VNC viewer main
-                        window, send the selection to the VNC server even if
-                        it has not changed.  This is like the Xt resource
-                        translation SelectionToVNC(always)
-
-        -recvtext str   When cut text is received from the VNC server,
-                        ssvncviewer will set both the X PRIMARY and the
-                        X CLIPBOARD local selections.  To control which
-                        is set, specify 'str' as 'primary', 'clipboard',
-                        or 'both' (the default.)
-
-        -graball    Grab the entire X server when in fullscreen mode,
-                    needed by some old window managers like fvwm2.
-
-        -popupfix   Warp the popup back to the pointer position,
-                    needed by some old window managers like fvwm2.
-        -sendclipboard  Send the X CLIPBOARD selection (i.e. Ctrl+C,
-                        Ctrl+V) instead of the X PRIMARY selection (mouse
-                        select and middle button paste.)
-
-        -sendalways     Whenever the mouse enters the VNC viewer main
-                        window, send the selection to the VNC server even if
-                        it has not changed.  This is like the Xt resource
-                        translation SelectionToVNC(always)
-
-        -recvtext str   When cut text is received from the VNC server,
-                        ssvncviewer will set both the X PRIMARY and the
-                        X CLIPBOARD local selections.  To control which
-                        is set, specify 'str' as 'primary', 'clipboard',
-                        or 'both' (the default.)
-
-        -graball    Grab the entire X server when in fullscreen mode,
-                    needed by some old window managers like fvwm2.
-
-        -popupfix   Warp the popup back to the pointer position,
-                    needed by some old window managers like fvwm2.
-
-        -grabkbd    Grab the X keyboard when in fullscreen mode,
-                    needed by some window managers. Same as -grabkeyboard.
-                    -grabkbd is the default, use -nograbkbd to disable.
-
-        -bs, -nobs  Whether or not to use X server Backingstore for the
-                    main viewer window.  The default is to not, mainly
-                    because most Linux, etc, systems X servers disable
-                    *all* Backingstore by default.  To re-enable it put
-
-                        Option "Backingstore"
-
-                    in the Device section of /etc/X11/xorg.conf.
-                    In -bs mode with no X server backingstore, whenever an
-                    area of the screen is re-exposed it must go out to the
-                    VNC server to retrieve the pixels. This is too slow.
-
-                    In -nobs mode, memory is allocated by the viewer to
-                    provide its own backing of the main viewer window. This
-                    actually makes some activities faster (changes in large
-                    regions) but can appear to "flash" too much.
-
-        -noshm      Disable use of MIT shared memory extension (not recommended
-)
-
-        -termchat   Do the UltraVNC chat in the terminal vncviewer is in
-                    instead of in an independent window.
-
-        -unixpw str Useful for logging into x11vnc in -unixpw mode. "str" is a
-                    string that allows many ways to enter the Unix Username
-                    and Unix Password.  These characters: username, newline,
-                    password, newline are sent to the VNC server after any VNC
-                    authentication has taken place.  Under x11vnc they are
-                    used for the -unixpw login.  Other VNC servers could do
-                    something similar.
-
-                    You can also indicate "str" via the environment
-                    variable SSVNC_UNIXPW.
-
-                    Note that the Escape key is actually sent first to tell
-                    x11vnc to not echo the Unix Username back to the VNC
-                    viewer. Set SSVNC_UNIXPW_NOESC=1 to override this.
-
-                    If str is ".", then you are prompted at the command line
-                    for the username and password in the normal way.  If str is
-                    "-" the stdin is read via getpass(3) for username@password.
-                    Otherwise if str is a file, it is opened and the first line
-                    read is taken as the Unix username and the 2nd as the
-                    password. If str prefixed by "rm:" the file is removed
-                    after reading. Otherwise, if str has a "@" character,
-                    it is taken as username@password. Otherwise, the program
-                    exits with an error. Got all that?
-
-     -repeater str  This is for use with UltraVNC repeater proxy described
-                    here: http://www.uvnc.com/addons/repeater.html.  The "str"
-                    is the ID string to be sent to the repeater.  E.g. ID:1234
-                    It can also be the hostname and port or display of the VNC
-                    server, e.g. 12.34.56.78:0 or snoopy.com:1.  Note that when
-                    using -repeater, the host:dpy on the cmdline is the repeate
-r
-                    server, NOT the VNC server.  The repeater will connect you.
-
-                    Example: vncviewer ... -repeater ID:3333 repeat.host:5900
-                    Example: vncviewer ... -repeater vhost:0 repeat.host:5900
-
-                    Use, e.g., '-repeater SCIII=ID:3210' if the repeater is a
-                    Single Click III (SSL) repeater (repeater_SSL.exe) and you
-                    are passing the SSL part of the connection through stunnel,
-                    socat, etc. This way the magic UltraVNC string 'testB'
-                    needed to work with the repeater is sent to it.
-
-     -rfbversion str Set the advertised RFB version.  E.g.: -rfbversion 3.6
-                    For some servers, e.g. UltraVNC this needs to be done.
-
-     -ultradsm      UltraVNC has symmetric private key encryption DSM plugins:
-                    http://www.uvnc.com/features/encryption.html. It is assumed
-                    you are using a unix program (e.g. our ultravnc_dsm_helper)
-                    to encrypt and decrypt the UltraVNC DSM stream. IN ADDITION
-                    TO THAT supply -ultradsm to tell THIS viewer to modify the
-                    RFB data sent so as to work with the UltraVNC Server. For
-                    some reason, each RFB msg type must be sent twice under DSM
-.
-
-     -mslogon user  Use Windows MS Logon to an UltraVNC server.  Supply the
-                    username or "1" to be prompted.  The default is to
-                    autodetect the UltraVNC MS Logon server and prompt for
-                    the username and password.
-
-                    IMPORTANT NOTE: The UltraVNC MS-Logon Diffie-Hellman
-                    exchange is very weak and can be brute forced to recover
-                    your username and password in a few seconds of CPU time.
-                    To be safe, be sure to use an additional encrypted tunnel
-                    (e.g. SSL or SSH) for the entire VNC session.
-
-     -chatonly      Try to be a client that only does UltraVNC text chat. This
-                    mode is used by x11vnc to present a chat window on the
-                    physical X11 console (i.e. chat with the person at the
-                    display).
-
-     -env VAR=VALUE To save writing a shell script to set environment variables
-,
-                    specify as many as you need on the command line.  For
-                    example, -env SSVNC_MULTIPLE_LISTEN=MAX:5 -env EDITOR=vi
-
-     -noipv6        Disable all IPv6 sockets.  Same as VNCVIEWER_NO_IPV6=1.
-
-     -noipv4        Disable all IPv4 sockets.  Same as VNCVIEWER_NO_IPV4=1.
-
-     -printres      Print out the Ssvnc X resources (appdefaults) and then exit
-                    You can save them to a file and customize them (e.g. the
-                    keybindings and Popup menu)  Then point to the file via
-                    XENVIRONMENT or XAPPLRESDIR.
-
-     -pipeline      Like TurboVNC, request the next framebuffer update as soon
-                    as possible instead of waiting until the end of the current
-                    framebuffer update coming in.  Helps 'pipeline' the updates
-.
-                    This is currently the default, use -nopipeline to disable.
-
-     -appshare      Enable features for use with x11vnc's -appshare mode where
-                    instead of sharing the full desktop only the application's
-                    windows are shared.  Viewer multilisten mode is used to
-                    create the multiple windows: -multilisten is implied.
-                    See 'x11vnc -appshare -help' more information on the mode.
-
-                    Features enabled in the viewer under -appshare are:
-                    Minimum extra text in the title, auto -ycrop is disabled,
-                    x11vnc -remote_prefix X11VNC_APPSHARE_CMD: message channel,
-                    x11vnc initial window position hints.  See also Escape Keys
-                    below for additional key and mouse bindings.
-
-     -escape str    This sets the 'Escape Keys' modifier sequence and enables
-                    escape keys mode.  When the modifier keys escape sequence
-                    is held down, the next keystroke is interpreted locally
-                    to perform a special action instead of being sent to the
-                    remote VNC server.
-
-                    Use '-escape default' for the default modifier sequence.
-                    (Unix: Alt_L,Super_L and MacOSX: Control_L,Meta_L)
-
-    Here are the 'Escape Keys: Help+Set' instructions from the Popup Menu:
-
-    Escape Keys:  Enter a comma separated list of modifier keys to be the
-    'escape sequence'.  When these keys are held down, the next keystroke is
-    interpreted locally to invoke a special action instead of being sent to
-    the remote VNC server.  In other words, a set of 'Hot Keys'.
-
-    To enable or disable this, click on 'Escape Keys: Toggle' in the Popup.
-
-    Here is the list of hot-key mappings to special actions:
-
-       r: refresh desktop  b: toggle bell   c: toggle full-color
-       f: file transfer    x: x11cursor     z: toggle Tight/ZRLE
-       l: full screen      g: graball       e: escape keys dialog
-       s: scale dialog     +: scale up (=)  -: scale down (_)
-       t: text chat                         a: alphablend cursor
-       V: toggle viewonly  Q: quit viewer   1 2 3 4 5 6: UltraVNC scale 1/n
-
-       Arrow keys:         pan the viewport about 10% for each keypress.
-       PageUp / PageDown:  pan the viewport by a screenful vertically.
-       Home   / End:       pan the viewport by a screenful horizontally.
-       KeyPad Arrow keys:  pan the viewport by 1 pixel for each keypress.
-       Dragging the Mouse with Button1 pressed also pans the viewport.
-       Clicking Mouse Button3 brings up the Popup Menu.
-
-    The above mappings are *always* active in ViewOnly mode, unless you set the
-    Escape Keys value to 'never'.
-
-    If the Escape Keys value below is set to 'default' then a default list of
-    of modifier keys is used.  For Unix it is: Alt_L,Super_L and for MacOSX it
-    is Control_L,Meta_L.  Note: the Super_L key usually has a Windows(TM) Flag
-    on it.  Also note the _L and _R mean the key is on the LEFT or RIGHT side
-    of the keyboard.
-
-    On Unix   the default is Alt and Windows keys on Left side of keyboard.
-    On MacOSX the default is Control and Command keys on Left side of keyboard.
-
-    Example: Press and hold the Alt and Windows keys on the LEFT side of the
-    keyboard and then press 'c' to toggle the full-color state.  Or press 't'
-    to toggle the ultravnc Text Chat window, etc.
-
-    To use something besides the default, supply a comma separated list (or a
-    single one) from: Shift_L Shift_R Control_L Control_R Alt_L Alt_R Meta_L
-    Meta_R Super_L Super_R Hyper_L Hyper_R or Mode_switch.

-
-   Windows:
-
-   For Windows, SSL Viewer support is provided by a GUI Windows/ssvnc.exe
-   that prompts for the VNC display and then starts up STUNNEL followed
-   by the Stock TightVNC Windows Viewer. Both are bundled in the package
-   for your convenience. The GUI has other useful features. When the
-   connection is finished, you will be asked if you want to terminate the
-   STUNNEL program. For SSH connections from Windows the GUI will use
-   PLINK instead of STUNNEL.
-
-   Unix and Mac OS X:
-
-   Run the GUI (ssvnc, see above) and let me know how it goes.
-     _________________________________________________________________
-
-   Hopefully this tool will make it convenient for people to help test
-   and use the built-in SSL support in x11vnc. Extra testing of this
-   feature is much appreciated!! Thanks.
-
-   Please Help Test the newly added features:
-     * Automatic Service tunnelling via SSH for CUPS and SMB Printing
-     * ESD/ARTSD Audio
-     * SMB (Windows/Samba) filesystem mounting
-
-   These allow you to print from the remote (VNC Server) machine to local
-   printers, listen to sounds (with some limitations) from the remote VNC
-   Server machine, and to mount your local Windows or Samba shares on the
-   remote VNC Server machine. Basically these new features try to
-   automate the tricks described here:

-
-   A quick guide:
-
-      On some flavor of Unix, e.g. Linux or Solaris? Use
-   "ssvnc_unix_only" (or "ssvnc_no_windows" to recompile).
-      On Mac OS X? Use "ssvnc_no_windows".
-      On Windows? Use "ssvnc_windows_only".

- VNCviewer  (0.5MB)
-
-   it will be of use to those who do not want the SSVNC
-   "one-size-fits-all" bundles. For example, package/distro maintainers
-   will find this more familiar and useful to them (i.e. they run: "make
-   config; make all; make install"). Note that it does not include the
-   stunnel source, and so has a dependency that the system stunnel is
-   installed.
-
-   Read the README.src file for more information on using the
-   conventional source tarball.
-
-
-   Note: even with the Unix bundles, e.g. "ssvnc_no_windows" or
-   "ssvnc_all", you may need to run the "./build.unix" script in the top
-   directory to recompile for your operating system.
-
-   Here are the corresponding 1.0.29 development bundles (Please help
-   test them):
-
-  ssvnc_windows_only-1.0.29.zip
-  ssvnc_no_windows-1.0.29.tar.gz
-  ssvnc_unix_only-1.0.29.tar.gz

- VNCviewer  (0.5MB)
-
-
-   For any Unix system, a self-extracting and running file for the
-   "ssvnc_unix_minimal" package is here: ssvnc. Save it as filename
-   "ssvnc", type "chmod 755 ./ssvnc", and then launch the GUI via typing
-   "./ssvnc". Note that this "ssvnc_unix_minimal" mode requires you
-   install the "stunnel" and "vncviewer" programs externally (for
-   example, install your distros' versions, e.g. on debian: "apt-get
-   install stunnel4 xtightvncviewer".) It will work, but many of the
-   SSVNC features will be missing.

-   Please help test the UltraVNC File Transfer support in the native Unix
-   VNC viewer! Let us know how it went.
-
-   Current Unix binaries in the archives:
-    Linux.i686
-    Linux.x86_64
-    Linux.ppc64    X (removed)
-    Linux.alpha    X (removed)
-    SunOS.sun4u
-    SunOS.sun4m
-    SunOS.i86pc
-    Darwin.Power.Macintosh
-    Darwin.i386
-    HP-UX.9000     X (removed)
-    FreeBSD.i386   X (removed)
-    NetBSD.i386    X (removed)
-    OpenBSD.i386   X (removed)
-
-   (some of these are out of date, marked with 'X' above, because I no
-   longer have access to machines running those OS's. Use the
-   "build.unix" script to recompile on your system).
-
-   Note: some of the above binaries depend on libssl.so.0.9.7, whereas
-   some recent distros only provide libssl.so.0.9.8 by default (for
-   compatibility reasons they should install both by default but not all
-   do). So you may need to instruct your distro to install the 0.9.7
-   library (it is fine to have both runtimes installed simultaneously
-   since the libraries have different names). Update: I now try to
-   statically link libssl.a for all of the binaries in the archive.
-
-   You can also run the included build.unix script to try to
-   automatically build the binaries if your OS is not in the above list
-   or the included binary does not run properly on your system. Let me
-   know how that goes.

-% x11vnc -help
-
-x11vnc: allow VNC connections to real X11 displays. 0.9.13 lastmod: 2010-12-27
-
-(type "x11vnc -opts" to just list the options.)
-
-Typical usage is:
-
-   Run this command in a shell on the remote machine "far-host"
-   with X session you wish to view:
-
-       x11vnc -display :0
-
-   Then run this in another window on the machine you are sitting at:
-
-       vncviewer far-host:0
-
-Once x11vnc establishes connections with the X11 server and starts listening
-as a VNC server it will print out a string: PORT=XXXX where XXXX is typically
-5900 (the default VNC server port).  One would next run something like
-this on the local machine: "vncviewer hostname:N" where "hostname" is
-the name of the machine running x11vnc and N is XXXX - 5900, i.e. usually
-"vncviewer hostname:0".
-
-By default x11vnc will not allow the screen to be shared and it will exit
-as soon as the client disconnects.  See -shared and -forever below to override
-these protections.  See the FAQ for details how to tunnel the VNC connection
-through an encrypted channel such as ssh(1).  In brief:
-
-       ssh -t -L 5900:localhost:5900 far-host 'x11vnc -localhost -display :0'
-
-       vncviewer -encodings 'copyrect tight zrle hextile' localhost:0
-
-Also, use of a VNC password (-rfbauth or -passwdfile) is strongly recommended.
-
-For additional info see: http://www.karlrunge.com/x11vnc/
-                    and  http://www.karlrunge.com/x11vnc/faq.html
-
-
-Config file support: if the file $HOME/.x11vncrc exists then each line in
-it is treated as a single command line option.  Disable with -norc.  For
-each option name, the leading character "-" is not required.  E.g. a line
-that is either "forever" or "-forever" may be used and are equivalent.
-Likewise "wait 100" or "-wait 100" are acceptable and equivalent lines.
-The "#" character comments out to the end of the line in the usual way
-(backslash it for a literal).  Leading and trailing whitespace is trimmed off.
-Lines may be continued with a "\" as the last character of a line (it
-becomes a space character).
-
-Options:
-
--display disp          X11 server display to connect to, usually :0.  The X
-                       server process must be running on same machine and
-                       support MIT-SHM.  Equivalent to setting the DISPLAY
-                       environment variable to "disp".
-
-                       See the description below of the "-display WAIT:..."
-                       extensions, where alias "-find" will find the user's
-                       display automatically, and "-create" will create a
-                       Xvfb session if no session is found.
-
--auth file             Set the X authority file to be "file", equivalent to
-                       setting the XAUTHORITY environment variable to "file"
-                       before startup.  Same as -xauth file.  See Xsecurity(7),
-                       xauth(1) man pages for more info.
-
-                       Use '-auth guess' to have x11vnc use its -findauth
-                       mechanism (described below) to try to guess the
-                       XAUTHORITY filename and use it.
-
-                       XDM/GDM/KDM: if you are running x11vnc as root and want
-                       to find the XAUTHORITY before anyone has logged into an
-                       X session yet, use: x11vnc -env FD_XDM=1 -auth guess ...
-                       (This will also find the XAUTHORITY if a user is already
-                       logged into the X session.)  When running as root,
-                       FD_XDM=1 will be tried if the initial -auth guess fails.
-
--N                     If the X display is :N, try to set the VNC display to
-                       also be :N This just sets the -rfbport option to 5900+N
-                       The program will exit immediately if that port is not
-                       available. The -N option only works with normal -display
-                       usage, e.g. :0 or :8, -N is ignored in the -display
-                       WAIT:..., -create, -find, -svc, -redirect, etc modes.
-
--autoport n            Automatically probe for a free VNC port starting at n.
-                       The default is to start probing at 5900.  Use this to
-                       stay away from other VNC servers near 5900.
-
--rfbport str           The VNC port to listen on (a LibVNCServer option), e.g.
-                       5900, 5901, etc.  If specified as "-rfbport PROMPT"
-                       then the x11vnc -gui is used to prompt the user to
-                       enter the port number.
-
--6                     IPv6 listening support.  In addition to IPv4, the
-                       IPv6 address is listened on for incoming connections.
-                       The same port number as IPv4 is used.
-
-                       NOTE:  This x11vnc binary was compiled to have the
-                       "-6" IPv6 listening mode ENABLED by default (CPPFLAGS
-                       -DX11VNC_LISTEN6=1).  So to disable IPv6 listening mode
-                       you MUST supply the "-no6" option (see below.)
-
-                       The "-6" mode works for both normal connections and
-                       -ssl encrypted ones.  Nearly everything is supported
-                       for the IPv6 case, but there are a few exceptions.
-                       See -stunnel for its IPv6 support.
-
-                       Currently, for absolutely everything to work correctly
-                       the machine may need to have some IPv4 support, at the
-                       least for the loopback interface.  However, for nearly
-                       all usage modes no IPv4 support is required. See -nopiv4
-.
-
-                       If you have trouble compiling or running in IPv6 mode,
-                       set -DX11VNC_IPV6=0 in CPPFLAGS when configuring to
-                       disable IPv6 support.
-
--no6                   Disable IPv6 listening support (only useful if the
-                       "-6" mode is compiled in to be the default; see the
-                       X11VNC_LISTEN6 description above under "-6".)
-
--noipv6                Do not try to use IPv6 for any listening or connecting
-                       sockets.  This includes both the listening service
-                       port(s) and outgoing connections from -connect,
-                       -connect_or_exit, or -proxy.  Use this if you are having
-                       problems due to IPv6.
-
--noipv4                Do not try to use IPv4 for any listening or connecting
-                       sockets.  This is mainly for exploring the behavior of
-                       x11vnc on an IPv6-only system, but may have other uses.
-
--reopen                If the X server connection is disconnected, try to
-                       reopen the X display (up to one time.)  This is of use
-                       for display managers like GDM (KillInitClients option)
-                       that kill x11vnc just after the user logs into the
-                       X session.  Note: the reopened state may be unstable.
-                       Set X11VNC_REOPEN_DISPLAY=n to reopen n times and
-                       set X11VNC_REOPEN_SLEEP_MAX to the number of seconds,
-                       default 10, to keep trying to reopen the display (once
-                       per second.)
-
-                       Update: as of 0.9.9, x11vnc tries to automatically avoid
-                       being killed by the display manager by delaying creating
-                       windows or using XFIXES.  So you shouldn't need to use
-                       KillInitClients=false as long as you log in quickly
-                       enough (within 45 seconds of connecting.)  You can
-                       disable this by setting X11VNC_AVOID_WINDOWS=never.
-                       You can also set it to the number of seconds to delay.
-
--reflect host:N        Instead of connecting to and polling an X display,
-                       connect to the remote VNC server host:N and be a
-                       reflector/repeater for it.  This is useful for trying
-                       to manage the case of many simultaneous VNC viewers
-                       (e.g. classroom broadcasting) where, e.g. you put
-                       a repeater on each network switch, etc, to improve
-                       performance by distributing the load and network
-                       traffic.  Implies -shared (use -noshared as a later
-                       option to disable). See the discussion below under
-                       -rawfb vnc:host:N for more details.
-
--id windowid           Show the X window corresponding to "windowid" not
-                       the entire display.  New windows like popup menus,
-                       transient toplevels, etc, may not be seen or may be
-                       clipped.  Disabling SaveUnders or BackingStore in the
-                       X server may help show them.  x11vnc may crash if the
-                       window is initially partially obscured, changes size,
-                       is iconified, etc.  Some steps are taken to avoid this
-                       and the -xrandr mechanism is used to track resizes.  Use
-                       xwininfo(1) to get the window id, or use "-id pick"
-                       to have x11vnc run xwininfo(1) for you and extract
-                       the id.  The -id option is useful for exporting very
-                       simple applications (e.g. the current view on a webcam).
--sid windowid          As -id, but instead of using the window directly it
-                       shifts a root view to it: this shows SaveUnders menus,
-                       etc, although they will be clipped if they extend beyond
-                       the window.
-
--appshare              Simple application sharing based on the -id/-sid
-                       mechanism.  Every new toplevel window that the
-                       application creates induces a new viewer window via
-                       a reverse connection.  The -id/-sid and -connect
-                       options are required.  Run 'x11vnc -appshare -help'
-                       for more info.
-
--clip WxH+X+Y          Only show the sub-region of the full display that
-                       corresponds to the rectangle geometry with size WxH and
-                       offset +X+Y.  The VNC display has size WxH (i.e. smaller
-                       than the full display).  This also works for -id/-sid
-                       mode where the offset is relative to the upper left
-                       corner of the selected window.  An example use of this
-                       option would be to split a large (e.g. Xinerama) display
-                       into two parts to be accessed via separate viewers by
-                       running a separate x11vnc on each part.
-
-                       Use '-clip xinerama0' to clip to the first xinerama
-                       sub-screen (if xinerama is active).  xinerama1 for the
-                       2nd sub-screen, etc.  This way you don't need to figure
-                       out the WxH+X+Y of the desired xinerama sub-screen.
-                       screens are sorted in increasing distance from the
-                       (0,0) origin (I.e. not the Xserver's order).
-
--flashcmap             In 8bpp indexed color, let the installed colormap flash
-                       as the pointer moves from window to window (slow).
-                       Also try the -8to24 option to avoid flash altogether.
--shiftcmap n           Rare problem, but some 8bpp displays use less than 256
-                       colorcells (e.g. 16-color grayscale, perhaps the other
-                       bits are used for double buffering) *and* also need to
-                       shift the pixels values away from 0, .., ncells.  "n"
-                       indicates the shift to be applied to the pixel values.
-                       To see the pixel values set DEBUG_CMAP=1 to print out
-                       a colormap histogram.  Example: -shiftcmap 240
--notruecolor           For 8bpp displays, force indexed color (i.e. a colormap)
-                       even if it looks like 8bpp TrueColor (rare problem).
--advertise_truecolor   If the X11 display is indexed color, lie to clients
-                       when they first connect by telling them it is truecolor.
-                       To workaround RealVNC: inPF has colourMap but not 8bpp
-                       Use '-advertise_truecolor reset' to reset client fb too.
-
--visual n              This option probably does not do what you think.
-                       It simply *forces* the visual used for the framebuffer;
-                       this may be a bad thing... (e.g. messes up colors or
-                       cause a crash). It is useful for testing and for some
-                       workarounds.  n may be a decimal number, or 0x hex.
-                       Run xdpyinfo(1) for the values.  One may also use
-                       "TrueColor", etc. see <X11/X.h> for a list.  If the
-                       string ends in ":m" then for better or for worse
-                       the visual depth is forced to be m.  You may want to
-                       use -noshm when using this option (so XGetImage may
-                       automatically translate the pixel data).
-
--overlay               Handle multiple depth visuals on one screen, e.g. 8+24
-                       and 24+8 overlay visuals (the 32 bits per pixel are
-                       packed with 8 for PseudoColor and 24 for TrueColor).
-
-                       Currently -overlay only works on Solaris via
-                       XReadScreen(3X11) and IRIX using XReadDisplay(3).
-                       On Solaris there is a problem with image "bleeding"
-                       around transient popup menus (but not for the menu
-                       itself): a workaround is to disable SaveUnders
-                       by passing the "-su" argument to Xsun (in
-                       /etc/dt/config/Xservers).
-
-                       Use -overlay as a workaround for situations like these:
-                       Some legacy applications require the default visual to
-                       be 8bpp (8+24), or they will use 8bpp PseudoColor even
-                       when the default visual is depth 24 TrueColor (24+8).
-                       In these cases colors in some windows will be incorrect
-                       in x11vnc unless -overlay is used.  Another use of
-                       -overlay is to enable showing the exact mouse cursor
-                       shape (details below).
-
-                       Under -overlay, performance will be somewhat slower
-                       due to the extra image transformations required.
-                       For optimal performance do not use -overlay, but rather
-                       configure the X server so that the default visual is
-                       depth 24 TrueColor and try to have all apps use that
-                       visual (e.g. some apps have -use24 or -visual options).
--overlay_nocursor      Sets -overlay, but does not try to draw the exact mouse
-                       cursor shape using the overlay mechanism.
-
--8to24 [opts]          Try this option if -overlay is not supported on your
-                       OS, and you have a legacy 8bpp app that you want to
-                       view on a multi-depth display with default depth 24
-                       (and is 32 bpp) OR have a default depth 8 display with
-                       depth 24 overlay windows for some apps.  This option
-                       may not work on all X servers and hardware (tested
-                       on XFree86/Xorg mga driver and Xsun).  The "opts"
-                       string is not required and is described below.
-
-                       This mode enables a hack where x11vnc monitors windows
-                       within 3 levels from the root window.  If it finds
-                       any that are 8bpp it extracts the indexed color
-                       pixel values using XGetImage() and then applies a
-                       transformation using the colormap(s) to create TrueColor
-                       RGB values that it in turn inserts into bits 1-24 of
-                       the framebuffer.  This creates a depth 24 "view"
-                       of the display that is then exported via VNC.
-
-                       Conversely, for default depth 8 displays, the depth
-                       24 regions are read by XGetImage() and everything is
-                       transformed and inserted into a depth 24 TrueColor
-                       framebuffer.
-
-                       Note that even if there are *no* depth 24 visuals or
-                       windows (i.e. pure 8bpp), this mode is potentially
-                       an improvement over -flashcmap because it avoids the
-                       flashing and shows each window in the correct color.
-
-                       This method works OK, but may still have bugs and it
-                       does hog resources.  If there are multiple 8bpp windows
-                       using different colormaps, one may have to iconify all
-                       but one for the colors to be correct.
-
-                       There may be painting errors for clipping and switching
-                       between windows of depths 8 and 24.  Heuristics are
-                       applied to try to minimize the painting errors.  One can
-                       also press 3 Alt_L's in a row to refresh the screen
-                       if the error does not repair itself.  Also the option
-                       -fixscreen 8=3.0 or -fixscreen V=3.0 may be used to
-                       periodically refresh the screen at the cost of bandwidth
-                       (every 3 sec for this example).
-
-                       The [opts] string can contain the following settings.
-                       Multiple settings are separated by commas.
-
-                       For for some X servers with default depth 24 a
-                       speedup may be achieved via the option "nogetimage".
-                       This enables a scheme were XGetImage() is not used
-                       to retrieve the 8bpp data.  Instead, it assumes that
-                       the 8bpp data is in bits 25-32 of the 32bit X pixels.
-                       There is no requirement that the X server should put
-                       the data there for our poll requests, but some do and
-                       so the extra steps to retrieve it can be skipped.
-                       Tested with mga driver with XFree86/Xorg.  For the
-                       default depth 8 case this option is ignored.
-
-                       To adjust how often XGetImage() is used to poll the
-                       non-default visual regions for changes, use the option
-                       "poll=t" where "t" is a floating point time.
-                       (default: 0.05)
-
-                       Setting the option "level2" will limit the search
-                       for non-default visual windows to two levels from the
-                       root window.  Do this on slow machines where you know
-                       the window manager only imposes one extra window between
-                       the app window and the root window.
-
-                       Also for very slow machines use "cachewin=t"
-                       where t is a floating point amount of time to cache
-                       XGetWindowAttributes results.  E.g. cachewin=5.0.
-                       This may lead to the windows being unnoticed for this
-                       amount of time when deiconifying, painting errors, etc.
-
-                       While testing on a very old SS20 these options gave
-                       tolerable response: -8to24 poll=0.2,cachewin=5.0. For
-                       this machine -overlay is supported and gives better
-                       response.
-
-                       Debugging for this mode can be enabled by setting
-                       "dbg=1", "dbg=2", or "dbg=3".
-
--24to32                Very rare problem: if the framebuffer (X display
-                       or -rawfb) is 24bpp instead of the usual 32bpp, then
-                       dynamically transform the pixels to 32bpp.  This will be
-                       slower, but can be used to work around problems where
-                       VNC viewers cannot handle 24bpp (e.g. "main: setPF:
-                       not 8, 16 or 32 bpp?").  See the FAQ for more info.
-
-                       In the case of -rawfb mode, the pixels are directly
-                       modified by inserting a 0 byte to pad them out to 32bpp.
-                       For X displays, a kludge is done that is equivalent to
-                       "-noshm -visual TrueColor:32".  (If better performance
-                       is needed for the latter, feel free to ask).
-
--scale fraction        Scale the framebuffer by factor "fraction".  Values
-                       less than 1 shrink the fb, larger ones expand it. Note:
-                       the image may not be sharp and response may be slower.
-                       If "fraction" contains a decimal point "." it
-                       is taken as a floating point number, alternatively
-                       the notation "m/n" may be used to denote fractions
-                       exactly, e.g. -scale 2/3
-
-                       To scale asymmetrically in the horizontal and vertical
-                       directions, specify a WxH geometry to stretch to:
-                       e.g. '-scale 1024x768', or also '-scale 0.9x0.75'
-
-                       Scaling Options: can be added after "fraction" via
-                       ":", to supply multiple ":" options use commas.
-                       If you just want a quick, rough scaling without
-                       blending, append ":nb" to "fraction" (e.g. -scale
-                       1/3:nb).  No blending is the default for 8bpp indexed
-                       color, to force blending for this case use ":fb".
-
-                       To disable -scrollcopyrect and -wirecopyrect under
-                       -scale use ":nocr".  If you need to to enable them use
-                       ":cr" or specify them explicitly on the command line.
-                       If a slow link is detected, ":nocr" may be applied
-                       automatically.  Default: :cr
-
-                       More esoteric options: for compatibility with vncviewers
-                       the scaled width is adjusted to be a multiple of 4:
-                       to disable this use ":n4".  ":in" use interpolation
-                       scheme even when shrinking, ":pad" pad scaled width
-                       and height to be multiples of scaling denominator
-                       (e.g. 3 for 2/3).
-
--geometry WxH          Same as -scale WxH
-
--scale_cursor frac     By default if -scale is supplied the cursor shape is
-                       scaled by the same factor.  Depending on your usage,
-                       you may want to scale the cursor independently of the
-                       screen or not at all.  If you specify -scale_cursor
-                       the cursor will be scaled by that factor.  When using
-                       -scale mode to keep the cursor at its "natural" size
-                       use "-scale_cursor 1".  Most of the ":" scaling
-                       options apply here as well.
-
--viewonly              All VNC clients can only watch (default off).
--shared                VNC display is shared, i.e. more than one viewer can
-                       connect at the same time (default off).
--once                  Exit after the first successfully connected viewer
-                       disconnects, opposite of -forever. This is the Default.
--forever               Keep listening for more connections rather than exiting
-                       as soon as the first client(s) disconnect. Same as -many
-
-                       To get the standard non-shared VNC behavior where when
-                       a new VNC client connects the existing VNC client is
-                       dropped use:  -nevershared -forever   This method can
-                       also be used to guard against hung TCP connections that
-                       do not go away.
-
--loop                  Create an outer loop restarting the x11vnc process
-                       whenever it terminates.  -bg and -inetd are ignored
-                       in this mode (however see -loopbg below).
-
-                       Useful for continuing even if the X server terminates
-                       and restarts (at that moment the process will need
-                       permission to reconnect to the new X server of course).
-
-                       Use, e.g., -loop100 to sleep 100 millisecs between
-                       restarts, etc.  Default is 2000ms (i.e. 2 secs) Use,
-                       e.g. -loop300,5 to sleep 300 ms and only loop 5 times.
-
-                       If -loopbg (plus any numbers) is specified instead,
-                       the "-bg" option is implied and the mode approximates
-                       inetd(8) usage to some degree.  In this case when
-                       it goes into the background any listening sockets
-                       (i.e. ports 5900, 5800) are closed, so the next one
-                       in the loop can use them.  This mode will only be of
-                       use if a VNC client (the only client for that process)
-                       is already connected before the process goes into the
-                       background, for example, usage of -display WAIT:..,
-                       -svc, and -connect can make use of this "poor man's"
-                       inetd mode.  The default wait time is 500ms in this
-                       mode.  This usage could use useful:  -svc -bg -loopbg
-
--timeout n             Exit unless a client connects within the first n seconds
-                       after startup.
-
-                       If there have been no connection attempts after n
-                       seconds x11vnc exits immediately.  If a client is
-                       trying to connect but has not progressed to the normal
-                       operating state, x11vnc gives it a few more seconds
-                       to finish and exits if it does not make it to the
-                       normal state.
-
-                       For reverse connections via -connect or -connect_or_exit
-                       a timeout of n seconds will be set for all reverse
-                       connects.  If the connect timeout alarm goes off,
-                       x11vnc will exit immediately.
-
--sleepin n             At startup sleep n seconds before proceeding (e.g. to
-                       allow redirs and listening clients to start up)
-
-                       If a range is given: '-sleepin min-max', a random value
-                       between min and max is slept. E.g. '-sleepin 0-20' and
-                       '-sleepin 10-30'.  Floats are allowed too.
-
--inetd                 Launched by inetd(8): stdio instead of listening socket.
-                       Note: if you are not redirecting stderr to a log file
-                       (via shell 2> or -o option) you MUST also specify the -q
-                       option, otherwise the stderr goes to the viewer which
-                       will cause it to abort.  Specifying both -inetd and -q
-                       and no -o will automatically close the stderr.
-
--tightfilexfer         Enable the TightVNC file transfer extension. Note that
-                       that when the -viewonly option is supplied all file
-                       transfers are disabled.  Also clients that log in
-                       viewonly cannot transfer files.  However, if the remote
-                       control mechanism is used to change the global or
-                       per-client viewonly state the filetransfer permissions
-                       will NOT change.
-
-                       IMPORTANT: please understand if -tightfilexfer is
-                       specified and you run x11vnc as root for, say, inetd
-                       or display manager (gdm, kdm, ...) access and you do
-                       not have it switch users via the -users option, then
-                       VNC Viewers that connect are able to do filetransfer
-                       reads and writes as *root*.
-
-                       Also, tightfilexfer is disabled in -unixpw mode.
-
--ultrafilexfer         Note: to enable UltraVNC filetransfer and to get it to
-                       work you probably need to supply these LibVNCServer
-                       options: "-rfbversion 3.6 -permitfiletransfer"
-                       "-ultrafilexfer" is an alias for this combination.
-
-                       IMPORTANT: please understand if -ultrafilexfer is
-                       specified and you run x11vnc as root for, say, inetd
-                       or display manager (gdm, kdm, ...) access and you do
-                       not have it switch users via the -users option, then
-                       VNC Viewers that connect are able to do filetransfer
-                       reads and writes as *root*.
-
-                       Note that sadly you cannot do both -tightfilexfer and
-                       -ultrafilexfer at the same time because the latter
-                       requires setting the version to 3.6 and tightvnc will
-                       not do filetransfer when it sees that version number.
-
--http                  Instead of using -httpdir (see below) to specify
-                       where the Java vncviewer applet is, have x11vnc try
-                       to *guess* where the directory is by looking relative
-                       to the program location and in standard locations
-                       (/usr/local/share/x11vnc/classes, etc).  Under -ssl or
-                       -stunnel the ssl classes subdirectory is sought.
--http_ssl              As -http, but force lookup for ssl classes subdir.
-
-                       Note that for HTTPS, single-port Java applet delivery
-                       you can set X11VNC_HTTPS_DOWNLOAD_WAIT_TIME to the
-                       max number of seconds to wait for the applet download
-                       to finish.  The default is 15.
-
--avahi                 Use the Avahi/mDNS ZeroConf protocol to advertise
-                       this VNC server to the local network. (Related terms:
-                       Rendezvous, Bonjour).  Depending on your setup, you
-                       may need to start avahi-daemon and open udp port 5353
-                       in your firewall.
-
-                       You can set X11VNC_AVAHI_NAME, X11VNC_AVAHI_HOST,
-                       and/or X11VNC_AVAHI_PORT environment variables
-                       to override the default values.  For example:
-                       -env X11VNC_AVAHI_NAME=wally
-
-                       If the avahi API cannot be found at build time, a helper
-                       program like avahi-publish(1) or dns-sd(1) will be tried
-
--mdns                  Same as -avahi.
--zeroconf              Same as -avahi.
-
--connect string        For use with "vncviewer -listen" reverse connections.
-                       If "string" has the form "host" or "host:port"
-                       the connection is made once at startup.
-
-                       Use commas for a list of host's and host:port's.
-                       E.g. -connect host1,host2 or host1:0,host2:5678.
-                       Note that to reverse connect to multiple hosts at the
-                       same time you will likely need to also supply: -shared
-
-                       Note that unlike most vnc servers, x11vnc will require a
-                       password for reverse as well as for forward connections.
-                       (provided password auth has been enabled, -rfbauth, etc)
-                       If you do not want to require a password for reverse
-                       connections set X11VNC_REVERSE_CONNECTION_NO_AUTH=1 in
-                       your environment before starting x11vnc.
-
-                       If "string" contains "/" it is instead interpreted
-                       as a file to periodically check for new hosts.
-                       The first line is read and then the file is truncated.
-                       Be careful about the location of this file if x11vnc
-                       is running as root (e.g. via gdm(1), etc).
-
-
-                       Repeater mode: Some services provide an intermediate
-                       "vnc repeater": http://www.uvnc.com/addons/repeater.html
-                       (and also http://koti.mbnet.fi/jtko/ for linux port)
-                       that acts as a proxy/gateway.  Modes like these require
-                       an initial string to be sent for the reverse connection
-                       before the VNC protocol is started.  Here are the ways
-                       to do this:
-
-                         -connect pre=some_string+host:port
-                         -connect pre128=some_string+host:port
-                         -connect repeater=ID:1234+host:port
-                         -connect repeater=23.45.67.89::5501+host:port
-
-                       SSVNC notation is also supported:
-
-                         -connect repeater://host:port+ID:1234
-
-                       As with normal -connect usage, if the repeater port is
-                       not supplied 5500 is assumed.
-
-                       The basic idea is between the special tag, e.g. "pre="
-                       and "+" is the pre-string to be sent.  Note that in
-                       this case host:port is the repeater server, NOT the
-                       vnc viewer.  Somehow the pre-string tells the repeater
-                       server how to find the vnc viewer and connect you to it.
-
-                       In the case pre=some_string+host:port, "some_string"
-                       is simply sent. In the case preNNN=some_string+host:port
-                       "some_string" is sent in a null padded buffer of
-                       length NNN.  repeater= is the same as pre250=, this is
-                       the ultravnc repeater buffer size.
-
-                       Strings like "\n" and "\r", etc. are expanded to
-                       newline and carriage return.  "\c" is expanded to
-                       "," since the connect string is comma separated.
-
-                       See also the -proxy option below for additional ways
-                       to plumb reverse connections.
-
-                       Reverse SSL: using -connect in -ssl mode makes x11vnc
-                       act as an SSL client (initiates SSL connection) rather
-                       than an SSL server.  The idea is x11vnc might be
-                       connecting to stunnel on the viewer side with the
-                       viewer in listening mode.  If you do not want this
-                       behavior, use -env X11VNC_DISABLE_SSL_CLIENT_MODE=1.
-                       With this the viewer side can act as the SSL client
-                       as it normally does for forward connections.
-
-                       Reverse SSL Repeater mode:  This will work, but note
-                       that if the VNC Client does any sort of a 'Fetch Cert'
-                       action before connecting, then the Repeater will
-                       likely drop the connection and both sides will need
-                       to restart.  Consider the use of -connect_or_exit
-                       and -loop300,2 to have x11vnc reconnect once to the
-                       repeater after the fetch.  You will probably also want
-                       to supply -sslonly to avoid x11vnc thinking the delay
-                       in response means the connection is VeNCrypt.  The env
-                       var X11VNC_DISABLE_SSL_CLIENT_MODE=1 discussed above
-                       may also be useful (i.e. the viewer can do a forward
-                       connection as it normally does.)
-
-                       IPv6: as of x11vnc 0.9.10 the -connect option should
-                       connect to IPv6 hosts properly.  If there are problems
-                       you can disable IPv6 by setting -DX11VNC_IPV6=0
-                       in CPPFLAGS when configuring.  If there problems
-                       connecting to IPv6 hosts consider a relay like the
-                       included inet6to4 script or the -proxy option.
-
--connect_or_exit str   As with -connect, except if none of the reverse
-                       connections succeed, then x11vnc shuts down immediately
-
-                       An easier to type alias for this option is '-coe'
-
-                       By the way, if you do not want x11vnc to listen on
-                       ANY interface use -rfbport 0  which is handy for the
-                       -connect_or_exit mode.
-
--proxy string          Use proxy in string (e.g. host:port) as a proxy for
-                       making reverse connections (-connect or -connect_or_exit
-                       options).
-
-                       Web proxies are supported, but note by default most of
-                       them only support destination connections to ports 443
-                       or 563, so this might not be very useful (the viewer
-                       would need to listen on that port or the router would
-                       have to do a port redirection).
-
-                       A web proxy may be specified by either "host:port"
-                       or "http://host:port" (the port is required even if
-                       it is the common choices 80 or 8080)
-
-                       SOCKS4, SOCKS4a, and SOCKS5 are also supported.
-                       SOCKS proxies normally do not have restrictions on the
-                       destination port number.
-
-                       Use a format like this: socks://host:port or
-                       socks5://host:port.  Note that ssh -D does not support
-                       SOCKS4a, so use socks5://.  For socks:// SOCKS4 is used
-                       on a numerical IP and "localhost", otherwise SOCKS4a
-                       is used (and so the proxy tries to do the DNS lookup).
-
-                       An experimental mode is "-proxy http://host:port/..."
-                       Note the "/" after the port that distinguishes it from
-                       a normal web proxy.  The port must be supplied even if
-                       it is the default 80.  For this mode a GET is done to
-                       the supplied URL with the string host=H&port=P appended.
-                       H and P will be the -connect reverse connect host
-                       and port.  Use the string "__END__" to disable the
-                       appending.  The basic idea here is that maybe some cgi
-                       script provides the actual viewer hookup and tunnelling.
-                       How to actually achieve this within cgi, php, etc. is
-                       not clear...  A custom web server or apache module
-                       would be straight-forward.
-
-                       Another experimental mode is "-proxy ssh://user@host"
-                       in which case a SSH tunnel is used for the proxying.
-                       "user@" is not needed unless your unix username is
-                       different on "host".  For a non-standard SSH port
-                       use ssh://user@host:port.  If proxies are chained (see
-                       next paragraph) then the ssh one must be the first one.
-                       If ssh-agent is not active, then the ssh password needs
-                       to be entered in the terminal where x11vnc is running.
-                       Examples:
-
-                         -connect localhost:0 -proxy ssh://me@friends-pc:2222
-
-                         -connect snoopy:0 -proxy ssh://ssh.company.com
-
-                       Multiple proxies may be chained together in case one
-                       needs to ricochet off of a number of hosts to finally
-                       reach the VNC viewer.  Up to 3 may be chained, separate
-                       them by commas in the order they are to be connected to.
-                       E.g.:  http://host1:port1,socks5://host2:port2 or three
-                       like:  first,second,third
-
-                       IPv6: as of x11vnc 0.9.10 the -proxy option should
-                       connect to IPv6 hosts properly.  If there are problems
-                       you can disable IPv6 by setting -DX11VNC_IPV6=0
-                       in CPPFLAGS when configuring.  If there problems
-                       connecting to IPv6 hosts consider a relay like the
-                       included inet6to4 script.
-
--vncconnect            Monitor the VNC_CONNECT X property set by the standard
--novncconnect          VNC program vncconnect(1).  When the property is
-                       set to "host" or "host:port" establish a reverse
-                       connection.  Using xprop(1) instead of vncconnect may
-                       work (see the FAQ).  The -remote control mechanism uses
-                       X11VNC_REMOTE channel, and this option disables/enables
-                       it as well.  Default: -vncconnect
-
-                       To use different names for these X11 properties (e.g. to
-                       have separate communication channels for multiple
-                       x11vnc's on the same display) set the VNC_CONNECT or
-                       X11VNC_REMOTE env. vars. to the string you want, for
-                       example: -env X11VNC_REMOTE=X11VNC_REMOTE_12345
-                       Both sides of the channel must use the same unique name.
-                       The same can be done for the internal X11VNC_TICKER
-                       property (heartbeat and timestamp) if desired.
-
--allow host1[,host2..] Only allow client connections from hosts matching
-                       the comma separated list of hostnames or IP addresses.
-                       Can also be a numerical IP prefix, e.g. "192.168.100."
-                       to match a simple subnet, for more control build
-                       LibVNCServer with libwrap support (See the FAQ).  If the
-                       list contains a "/" it instead is a interpreted
-                       as a file containing addresses or prefixes that is
-                       re-read each time a new client connects.  Lines can be
-                       commented out with the "#" character in the usual way.
-
-                       -allow applies in -ssl mode, but not in -stunnel mode.
-
-                       IPv6: as of x11vnc 0.9.10 a host can be specified
-                       in IPv6 numerical format, e.g. 2001:4860:b009::93.
-
--localhost             Basically the same as "-allow 127.0.0.1".
-
-                       Note: if you want to restrict which network interface
-                       x11vnc listens on, see the -listen option below.
-                       E.g. "-listen localhost" or "-listen 192.168.3.21".
-                       As a special case, the option "-localhost" implies
-                       "-listen localhost".
-
-                       A rare case, but for non-localhost -listen usage, if
-                       you use the remote control mechanism (-R) to change
-                       the -listen interface you may need to manually adjust
-                       the -allow list (and vice versa) to avoid situations
-                       where no connections (or too many) are allowed.
-
-                       If you do not want x11vnc to listen on ANY interface
-                       (evidently you are using -connect or -connect_or_exit,
-                       or plan to use remote control: -R connect:host), use
-                       -rfbport 0
-
-                       IPv6: if IPv6 is supported, this option automatically
-                       implies the IPv6 loopback address '::1' as well.
-
--unixsock str          Listen on the unix socket (AF_UNIX) 'str'
-                       for connections.  This mode is for either local
-                       connections or a tunnel endpoint where one wants the
-                       file permission of the unix socket file to determine
-                       what can connect to it.  (This currently requires an
-                       edit to libvnserver/rfbserver.c: comment out lines 310
-                       and 311, 'close(sock)' and 'return NULL' in rfbserver.c
-                       after the setsockopt() call.) Note that to disable all
-                       tcp listening ports specify '-rfbport 0' and should be
-                       useful with this mode.  Example:
-                           mkdir ~/s; chmod 700 ~/s;
-                           x11vnc -unixsock ~/s/mysock -rfbport 0 ...
-                       The SSVNC unix vncviewer can connect to unix sockets.
-
--listen6 str           When in IPv6 listen mode "-6", listen only on the
-                       network interface with address "str".  It also works
-                       for link scope addresses (fe80::219:dbff:fee5:3f92%eth0)
-                       and IPv6 hostname strings (e.g. ipv6.google.com.)
-                       Use LibVNCServer -listen option for the IPv4 interface.
-
--nolookup              Do not use gethostbyname() or gethostbyaddr() to look up
-                       host names or IP numbers.  Use this if name resolution
-                       is incorrectly set up and leads to long pauses as name
-                       lookups time out, etc.
-
--input string          Fine tuning of allowed user input.  If "string" does
-                       not contain a comma "," the tuning applies only to
-                       normal clients.  Otherwise the part before "," is
-                       for normal clients and the part after for view-only
-                       clients.  "K" is for Keystroke input, "M" for
-                       Mouse-motion input, "B" for Button-click input, "C"
-                       is for Clipboard input, and "F" is for File transfer
-                       (ultravnc only).  Their presence in the string enables
-                       that type of input.  E.g. "-input M" means normal
-                       users can only move the mouse and  "-input KMBCF,M"
-                       lets normal users do anything and enables view-only
-                       users to move the mouse.  This option is ignored when
-                       a global -viewonly is in effect (all input is discarded
-                       in that case).
-
--grabkbd               When VNC viewers are connected, attempt to the grab
-                       the keyboard so a (non-malicious) user sitting at the
-                       physical display is not able to enter keystrokes.
-                       This method uses XGrabKeyboard(3X11) and so it is
-                       not secure and does not rule out the person at the
-                       physical display injecting keystrokes by flooding the
-                       server with them, grabbing the keyboard himself, etc.
-                       Some degree of cooperation from the person at the
-                       display is assumed.  This is intended for remote
-                       help-desk or educational usage modes.
-
-                       Note: on some recent (12/2010) X servers and/or
-                       desktops, -grabkbd no longer works: it prevents the
-                       window manager from resizing windows and similar things.
-                       Try -ungrabboth below (might not work.)
-
--grabptr               As -grabkbd, but for the mouse pointer using
-                       XGrabPointer(3X11).  Unfortunately due to the way the X
-                       server works, the mouse can still be moved around by the
-                       user at the physical display, but he will not be able to
-                       change window focus with it.  Also some window managers
-                       that call XGrabServer(3X11) for resizes, etc, will
-                       act on the local user's input.  Again, some degree of
-                       cooperation from the person at the display is assumed.
-
--ungrabboth            Whenever there is any input (either keyboard or
-                       pointer), ungrab *both* the keyboard and the pointer
-                       while injecting the synthetic input.  This is to allow
-                       window managers, etc. a chance to grab.
-
--grabalways            Apply both -grabkbd and -grabptr even when no VNC
-                       viewers are connected.  If you only want one of them,
-                       use the -R remote control to turn the other back on,
-                       e.g. -R nograbptr.
-
--viewpasswd string     Supply a 2nd password for view-only logins.  The -passwd
-                       (full-access) password must also be supplied.
-
--passwdfile filename   Specify the LibVNCServer password via the first line
-                       of the file "filename" (instead of via -passwd on
-                       the command line where others might see it via ps(1)).
-
-                       See the descriptions below for how to supply multiple
-                       passwords, view-only passwords, to specify external
-                       programs for the authentication, and other features.
-
-                       If the filename is prefixed with "rm:" it will be
-                       removed after being read.  Perhaps this is useful in
-                       limiting the readability of the file.  In general, the
-                       password file should not be readable by untrusted users
-                       (BTW: neither should the VNC -rfbauth file: it is NOT
-                       encrypted, only obscured with a fixed key).
-
-                       If the filename is prefixed with "read:" it will
-                       periodically be checked for changes and reread.  It is
-                       guaranteed to be reread just when a new client connects
-                       so that the latest passwords will be used.
-
-                       If "filename" is prefixed with "cmd:" then the
-                       string after the ":" is run as an external command:
-                       the output of the command will be interpreted as if it
-                       were read from a password file (see below).  If the
-                       command does not exit with 0, then x11vnc terminates
-                       immediately.  To specify more than 1000 passwords this
-                       way set X11VNC_MAX_PASSWDS before starting x11vnc.
-                       The environment variables are set as in -accept.
-
-                       Note that due to the VNC protocol only the first 8
-                       characters of a password are used (DES key).
-
-                       If "filename" is prefixed with "custom:" then a
-                       custom password checker is supplied as an external
-                       command following the ":". The command will be run
-                       when a client authenticates.  If the command exits with
-                       0 the client is accepted, otherwise it is rejected.
-                       The environment variables are set as in -accept.
-
-                       The standard input to the custom command will be a
-                       decimal digit "len" followed by a newline. "len"
-                       specifies the challenge size and is usually 16 (the
-                       VNC spec).  Then follows len bytes which is the random
-                       challenge string that was sent to the client. This is
-                       then followed by len more bytes holding the client's
-                       response (i.e. the challenge string encrypted via DES
-                       with the user password in the standard situation).
-
-                       The "custom:" scheme can be useful to implement
-                       dynamic passwords or to implement methods where longer
-                       passwords and/or different encryption algorithms
-                       are used.  The latter will require customizing the VNC
-                       client as well.  One could create an MD5SUM based scheme
-                       for example.
-
-                       File format for -passwdfile:
-
-                       If multiple non-blank lines exist in the file they are
-                       all taken as valid passwords.  Blank lines are ignored.
-                       Password lines may be "commented out" (ignored) if
-                       they begin with the character "#" or the line contains
-                       the string "__SKIP__".  Lines may be annotated by use
-                       of the "__COMM__" string: from it to the end of the
-                       line is ignored.  An empty password may be specified
-                       via the "__EMPTY__" string on a line by itself (note
-                       your viewer might not accept empty passwords).
-
-                       If the string "__BEGIN_VIEWONLY__" appears on a
-                       line by itself, the remaining passwords are used for
-                       viewonly access.  For compatibility, as a special case
-                       if the file contains only two password lines the 2nd
-                       one is automatically taken as the viewonly password.
-                       Otherwise the "__BEGIN_VIEWONLY__" token must be
-                       used to have viewonly passwords.  (tip: make the 3rd
-                       and last line be "__BEGIN_VIEWONLY__" to have 2
-                       full-access passwords)
-
--showrfbauth filename  Print to the screen the obscured VNC password kept in
-                       the rfbauth file "filename" and then exit.
-
--unixpw [list]         Use Unix username and password authentication.  x11vnc
-                       will use the su(1) program to verify the user's
-                       password.  [list] is an optional comma separated list
-                       of allowed Unix usernames.  If the [list] string begins
-                       with the character "!" then the entire list is taken
-                       as an exclude list.  See below for per-user options
-                       that can be applied.
-
-                       A familiar "login:" and "Password:" dialog is
-                       presented to the user on a black screen inside the
-                       vncviewer.  The connection is dropped if the user fails
-                       to supply the correct password in 3 tries or does not
-                       send one before a 45 second timeout.  Existing clients
-                       are view-only during this period.
-
-                       If the first character received is "Escape" then the
-                       unix username will not be displayed after "login:"
-                       as it is typed.  This could be of use for VNC viewers
-                       that automatically type the username and password.
-
-                       Since the detailed behavior of su(1) can vary from
-                       OS to OS and for local configurations, test the mode
-                       before deployment to make sure it is working properly.
-                       x11vnc will attempt to be conservative and reject a
-                       login if anything abnormal occurs.
-
-                       One case to note: FreeBSD and the other BSD's by
-                       default it is impossible for the user running x11vnc to
-                       validate his *own* password via su(1) (commenting out
-                       the pam_self.so entry in /etc/pam.d/su eliminates this
-                       behavior).  So the x11vnc login will always *FAIL* for
-                       this case (even when the correct password is supplied).
-
-                       A possible workaround for this on *BSD would be to
-                       start x11vnc as root with the "-users +nobody" option
-                       to immediately switch to user nobody where the su'ing
-                       will proceed normally.
-
-                       Another source of potential problems are PAM modules
-                       that prompt for extra info, e.g. password aging modules.
-                       These logins will fail as well even when the correct
-                       password is supplied.
-
-                       **IMPORTANT**: to prevent the Unix password being sent
-                       in *clear text* over the network, one of two schemes
-                       will be enforced: 1) the -ssl builtin SSL mode, or 2)
-                       require both -localhost and -stunnel be enabled.
-
-                       Method 1) ensures the traffic is encrypted between
-                       viewer and server.  A PEM file will be required, see the
-                       discussion under -ssl below (under some circumstances
-                       a temporary one can be automatically generated).
-
-                       Method 2) requires the viewer connection to appear
-                       to come from the same machine x11vnc is running on
-                       (e.g. from a ssh -L port redirection).  And that the
-                       -stunnel SSL mode be used for encryption over the
-                       network. (see the description of -stunnel below).
-
-                       Note: as a convenience, if you ssh(1) in and start
-                       x11vnc it will check if the environment variable
-                       SSH_CONNECTION is set and appears reasonable.  If it
-                       does, then the -ssl or -stunnel requirement will be
-                       dropped since it is assumed you are using ssh for the
-                       encrypted tunnelling.  -localhost is still enforced.
-                       Use -ssl or -stunnel to force SSL usage even if
-                       SSH_CONNECTION is set.
-
-                       To override the above restrictions you can set
-                       environment variables before starting x11vnc:
-
-                       Set UNIXPW_DISABLE_SSL=1 to disable requiring either
-                       -ssl or -stunnel (as under SSH_CONNECTION.)  Evidently
-                       you will be using a different method to encrypt the
-                       data between the vncviewer and x11vnc: perhaps ssh(1)
-                       or an IPSEC VPN. -localhost is still enforced (however,
-                       see the next paragraph.)
-
-                       Set UNIXPW_DISABLE_LOCALHOST=1 to disable the -localhost
-                       requirement in -unixpw modes.  One should never do this
-                       (i.e. allow the Unix passwords to be sniffed on the
-                       network.)  This also disables the localhost requirement
-                       for reverse connections (see below.)
-
-                       Note that use of -localhost with ssh(1) (and no -unixpw)
-                       is roughly the same as requiring a Unix user login
-                       (since a Unix password or the user's public key
-                       authentication is used by sshd on the machine where
-                       x11vnc runs and only local connections from that machine
-                       are accepted).
-
-                       Regarding reverse connections (e.g. -R connect:host
-                       and -connect host), when the -localhost constraint is
-                       in effect then reverse connections can only be used
-                       to connect to the same machine x11vnc is running on
-                       (default port 5500).  Please use a ssh or stunnel port
-                       redirection to the viewer machine to tunnel the reverse
-                       connection over an encrypted channel.
-
-                       In -inetd mode the Method 1) will be enforced (not
-                       Method 2).  With -ssl in effect reverse connections
-                       are disabled.  If you override this via env. var, be
-                       sure to also use encryption from the viewer to inetd.
-                       Tip: you can also have your own stunnel spawn x11vnc
-                       in -inetd mode (thereby bypassing inetd).  See the FAQ
-                       for details.
-
-                       The user names in the comma separated [list] may have
-                       per-user options after a ":", e.g. "fred:opts"
-                       where "opts" is a "+" separated list of
-                       "viewonly", "fullaccess", "input=XXXX", or
-                       "deny", e.g. "karl,wally:viewonly,boss:input=M".
-                       For "input=" it is the K,M,B,C described under -input.
-
-                       If an item in the list is "*" that means those
-                       options apply to all users.  It ALSO implies all users
-                       are allowed to log in after supplying a valid password.
-                       Use "deny" to explicitly deny some users if you use
-                       "*" to set a global option.  If [list] begins with the
-                       "!" character then "*" is ignored for checking if
-                       the user is allowed, but the option values associated
-                       with it do apply as normal.
-
-                       There are also some utilities for checking passwords
-                       if [list] starts with the "%" character.  See the
-                       quick_pw() function for more details.  Description:
-                       "%-" or "%stdin" means read one line from stdin.
-                       "%env" means it is in $UNIXPW env var.  A leading
-                       "%/" or "%." means read the first line from the
-                       filename that follows after the % character. % by
-                       itself means prompt for the username and password.
-                       Otherwise: %user:pass   E.g. -unixpw %fred:swordfish
-                       For the other cases user:pass is read from the indicated
-                       source.  If the password is correct 'Y user' is printed
-                       and the program exit code is 0.  If the password is
-                       incorrect it prints 'N user' and the exit code is 1.
-                       If there is some other error the exit code is 2.
-                       This feature enables x11vnc to be a general unix user
-                       password checking tool; it could be used from scripts
-                       or other programs.  These % password checks also apply
-                       to the -unixpw_nis and -unixpw_cmd options.
-
-                       For the % password check, if the env. var. UNIXPW_CMD
-                       is set to a command then it is run as the user (assuming
-                       the password is correct.)  The output of the command is
-                       not printed, the program or script must manage that by
-                       some other means.  The exit code of x11vnc will depend
-                       on the exit code of the command that is run.
-
-                       Use -nounixpw to disable unixpw mode if it was enabled
-                       earlier in the cmd line (e.g. -svc mode)
-
--unixpw_nis [list]     As -unixpw above, however do not use su(1) but rather
-                       use the traditional getpwnam(3) + crypt(3) method to
-                       verify passwords. All of the above -unixpw options and
-                       constraints apply.
-
-                       This mode requires that the encrypted passwords be
-                       readable.  Encrypted passwords stored in /etc/shadow
-                       will be inaccessible unless x11vnc is run as root.
-
-                       This is called "NIS" mode simply because in most
-                       NIS setups user encrypted passwords are accessible
-                       (e.g. "ypcat passwd") by an ordinary user and so that
-                       user can authenticate ANY user.
-
-                       NIS is not required for this mode to work (only that
-                       getpwnam(3) return the encrypted password is required),
-                       but it is unlikely it will work (as an ordinary user)
-                       for most modern environments unless NIS is available.
-                       On the other hand, when x11vnc is run as root it will
-                       be able to to access /etc/shadow even if NIS is not
-                       available (note running as root is often done when
-                       running x11vnc from inetd and xdm/gdm/kdm).
-
-                       Looked at another way, if you do not want to use the
-                       su(1) method provided by -unixpw (i.e. su_verify()), you
-                       can run x11vnc as root and use -unixpw_nis.  Any users
-                       with passwords in /etc/shadow can then be authenticated.
-
-                       In -unixpw_nis mode, under no circumstances is x11vnc's
-                       user password verifying function based on su called
-                       (i.e. the function su_verify() that runs /bin/su
-                       in a pseudoterminal to verify passwords.)  However,
-                       if -unixpw_nis is used in conjunction with the -find
-                       and -create -display WAIT:... modes then, if x11vnc is
-                       running as root, /bin/su may be called externally to
-                       run the find or create commands.
-
--unixpw_cmd cmd        As -unixpw above, however do not use su(1) but rather
-                       run the externally supplied command "cmd".  The first
-                       line of its stdin will be the username and the second
-                       line the received password.  If the command exits
-                       with status 0 (success) the VNC user will be accepted.
-                       It will be rejected for any other return status.
-
-                       Dynamic passwords and non-unix passwords, e.g. LDAP,
-                       can be implemented this way by providing your own custom
-                       helper program.  Note that the remote viewer is given 3
-                       tries to enter the correct password, and so the program
-                       may be called in a row that many (or more) times.
-
-                       If a list of allowed users is needed to limit who can
-                       log in, use -unixpw [list] in addition to this option.
-
-                       In FINDDISPLAY and FINDCREATEDISPLAY modes the "cmd"
-                       will also be run with the RFB_UNIXPW_CMD_RUN env. var.
-                       non-empty and set to the corresponding display
-                       find/create command.  The first two lines of input are
-                       the username and passwd as in the normal case described
-                       above.  To support FINDDISPLAY and FINDCREATEDISPLAY,
-                       "cmd" should run the requested command as the user
-                       (and most likely refusing to run it if the password is
-                       not correct.)  Here is an example script (note it has
-                       a hardwired bogus password "abc"!)
-
-                         #!/bin/sh
-                         # Example x11vnc -unixpw_cmd script.
-                         # Read the first two lines of stdin (user and passwd)
-                         read user
-                         read pass

-                         # (A real example would use ldap lookup, etc!)
-                         if [ "X$pass" != "Xabc" ]; then
-                                exit 1  # incorrect password
-                         fi

-                         else
-                                # Run the requested command (finddisplay)
-                                if [ $debug = 1 ]; then
-                                        echo "run: $RFB_UNIXPW_CMD_RUN" 1>&2
-                                fi

-
-                       In -unixpw_cmd mode, under no circumstances is x11vnc's
-                       user password verifying function based on su called
-                       (i.e. the function su_verify() that runs /bin/su in a
-                       pseudoterminal to verify passwords.)  It is up to the
-                       supplied unixpw_cmd to do user switching if desired
-                       and if it has the permissions to do so.
-
--find                  Find the user's display using FINDDISPLAY. This
-                       is an alias for "-display WAIT:cmd=FINDDISPLAY".
-
-                       Note: if a -display occurs later on the command line
-                       it will override the -find setting.
-
-                       For this and the next few options see -display WAIT:...
-                       below for all of the details.
-
--finddpy               Run the FINDDISPLAY program, print out the found
-                       display (if any) and exit.  Output is like: DISPLAY=:0.0
-                       DISPLAY=:0.0,XPID=12345 or DISPLAY=:0.0,VT=7.  XPID is
-                       the process ID of the found X server.  VT is the Linux
-                       virtual terminal of the X server.
--listdpy               Have the FINDDISPLAY program list all of your displays
-                       (i.e. all the X displays on the local machine that you
-                       have access rights to).  x11vnc then exits.
-
--findauth [disp]       Apply the -find/-finddpy heuristics to try to guess
-                       the XAUTHORITY file for DISPLAY 'disp'.  If 'disp'
-                       is not supplied, then the value in the -display on
-                       the cmdline is used; failing that $DISPLAY is used;
-                       and failing that ":0" is used.  x11vnc then exits.
-
-                       If nothing is printed out, that means no XAUTHORITY was
-                       found for 'disp'; i.e. failure.  If "XAUTHORITY="
-                       is printed out, that means use the default (i.e. do
-                       not set XAUTHORITY).  If "XAUTHORITY=/path/to/file"
-                       is printed out, then use that file.
-
-                       XDM/GDM/KDM: if you are running x11vnc as root and want
-                       to find the XAUTHORITY before anyone has logged into an
-                       X session yet, use: x11vnc -env FD_XDM=1 -findauth ...
-                       (This will also find the XAUTHORITY if a user is already
-                       logged into the X session.)  When running as root,
-                       FD_XDM=1 will be tried if the initial -findauth fails.
-
--create                First try to find the user's display using FINDDISPLAY,
-                       if that doesn't succeed create an X session via the
-                       FINDCREATEDISPLAY method.  This is an alias for
-                       "-display WAIT:cmd=FINDCREATEDISPLAY-Xvfb".
-
-                       Note: if a -display occurs later on the command line
-                       it will override the -create setting.
-
-                       SSH NOTE: for both -find and -create you can (should!)
-                       add the "-localhost" option to force SSH tunnel access.
-
--xdummy                As in -create, except Xdummy instead of Xvfb.
--xvnc                  As in -create, except Xvnc instead of Xvfb.
--xvnc_redirect         As in -create, except Xvnc.redirect instead of Xvfb.
--xdummy_xvfb           Sets WAIT:cmd=FINDCREATEDISPLAY-Xdummy,Xvfb
-
--create_xsrv str       Sets WAIT:cmd=FINDCREATEDISPLAY-<str>  Can be on cmdline
-                       after anything that sets WAIT:.. and other things
-                       (e.g. -svc, -xdmsvc) to adjust the X server list.
-                       Example: -svc ... -create_xsrv Xdummy,X
-
--svc                   Terminal services mode based on SSL access.  Alias for
-                       -display WAIT:cmd=FINDCREATEDISPLAY-Xvfb -unixpw -users
-                       unixpw= -ssl SAVE   Also "-service".
-
-                       Note: if a -display, -unixpw, -users, or -ssl occurs
-                       later on the command line it will override the -svc
-                       setting.
-
--svc_xdummy            As -svc except Xdummy instead of Xvfb.
--svc_xvnc              As -svc except Xvnc instead of Xvfb.
--svc_xdummy_xvfb       As -svc with Xdummy,Xvfb.
-
--xdmsvc                Display manager Terminal services mode based on SSL.
-                       Alias for -display WAIT:cmd=FINDCREATEDISPLAY-Xvfb.xdmcp
-                       -unixpw -users unixpw= -ssl SAVE  Also "-xdm_service".
-
-                       Note: if a -display, -unixpw, -users, or -ssl occurs
-                       later on the command line it will override the -xdmsvc
-                       setting.
-
-                       To create a session a user will have to first log in
-                       to the -unixpw dialog and then log in again to the
-                       XDM/GDM/KDM prompt.  Subsequent re-connections will
-                       only require the -unixpw password.  See the discussion
-                       under -display WAIT:... for more details about XDM,
-                       etc configuration.
-
-                       Remember to enable XDMCP in the xdm-config, gdm.conf,
-                       or kdmrc configuration file.  See -display WAIT: for
-                       more info.
-
--sshxdmsvc             Display manager Terminal services mode based on SSH.
-                       Alias for -display WAIT:cmd=FINDCREATEDISPLAY-Xvfb.xdmcp
-                       -localhost.
-
-                       The -localhost option constrains connections to come
-                       in via a SSH tunnel (which will require a login).
-                       To create a session a user will also have to log into
-                       the XDM GDM KDM prompt. Subsequent re-connections will
-                       only only require the SSH login.  See the discussion
-                       under -display WAIT:... for more details about XDM,
-                       etc configuration.
-
-                       Remember to enable XDMCP in the xdm-config, gdm.conf,
-                       or kdmrc configuration file.  See -display WAIT: for
-                       more info.
-
--unixpw_system_greeter Present a "Press 'Escape' for System Greeter" option
-                       to the connecting VNC client in combined -unixpw
-                       and xdmcp FINDCREATEDISPLAY modes (e.g. -xdmsvc).
-
-                       Normally in a -unixpw mode the VNC client must
-                       supply a valid username and password to gain access.
-                       However, if -unixpw_system_greeter is supplied AND
-                       the FINDCREATEDISPLAY command matches 'xdmcp', then
-                       the user has the option to press Escape and then get a
-                       XDM/GDM/KDM login/greeter panel instead. They will then
-                       supply a username and password directly to the greeter.
-
-                       Otherwise, in xdmcp FINDCREATEDISPLAY mode the user
-                       must supply his username and password TWICE.  First to
-                       the initial unixpw login dialog, and second to the
-                       subsequent XDM/GDM/KDM greeter.  Note that if the user
-                       re-connects and supplies his username and password in
-                       the unixpw dialog the xdmcp greeter is skipped and
-                       he is connected directly to his existing X session.
-                       So the -unixpw_system_greeter option avoids the extra
-                       password at X session creation time.
-
-                       Example:  x11vnc -xdmsvc -unixpw_system_greeter
-                       See -unixpw and -display WAIT:... for more info.
-
-                       The special options after a colon at the end of the
-                       username (e.g. user:solid) described under -display
-                       WAIT: are also applied in this mode if they are typed
-                       in before the user hits Escape.  The username is ignored
-                       but the colon options are not.
-
-                       The default message is 2 lines in a small font, set
-                       the env. var. X11VNC_SYSTEM_GREETER1=true for a 1 line
-                       message in a larger font.
-
-                       If the user pressed Escape the FINDCREATEDISPLAY command
-                       will be run with the env. var. X11VNC_XDM_ONLY=1.
-
-                       Remember to enable XDMCP in the xdm-config, gdm.conf,
-                       or kdmrc configuration file.  See -display WAIT: for
-                       more info.
-
--redirect port         As in FINDCREATEDISPLAY-Xvnc.redirect mode except
-                       redirect immediately (i.e. without X session finding
-                       or creation) to a VNC server listening on port. You
-                       can also supply host:port to redirect to a different
-                       machine.
-
-                       If 0 <= port < 200 it is taken as a VNC display (5900 is
-                       added to get the actual port), if port < 0 then -port
-                       is used.
-
-                       Probably the only reason to use the -redirect option
-                       is in conjunction with SSL support, e.g. -ssl SAVE.
-                       This provides an easy way to add SSL encryption to a VNC
-                       server that does not support SSL (e.g. Xvnc or vnc.so)
-                       In fact, the protocol does not even need to be VNC,
-                       and so "-rfbport port1 -ssl SAVE -redirect host:port2"
-                       can act as a replacement for stunnel(1).
-
-                       This mode only allows one redirected connection.
-                       The -forever option does not apply.  Use -inetd or
-                       -loop for persistent service.
-
--display_WAIT :...      A special usage mode for the normal -display option.
-                       Useful with -unixpw, but can be used independently
-                       of it.  If the display string begins with WAIT: then
-                       x11vnc waits until a VNC client connects before opening
-                       the X display (or -rawfb device).
-
-                       This could be useful for delaying opening the display
-                       for certain usage modes (say if x11vnc is started at
-                       boot time and no X server is running or users logged
-                       in yet).
-
-                       If the string is, e.g. WAIT:0.0 or WAIT:1, i.e. "WAIT"
-                       in front of a normal X display, then that indicated
-                       display is used.
-
-                       One can also insert a geometry between colons, e.g.
-                       WAIT:1280x1024:... to set the size of the display the
-                       VNC client first attaches to since some VNC viewers
-                       will not automatically adjust to a new framebuffer size.
-
-                       A more interesting case is like this:
-
-                            WAIT:cmd=/usr/local/bin/find_display
-
-                       in which case the command after "cmd=" is run to
-                       dynamically work out the DISPLAY and optionally the
-                       XAUTHORITY data.  The first line of the command output
-                       must be of the form DISPLAY=<xdisplay>.  On Linux
-                       if the virtual terminal is known append ",VT=n" to
-                       this string and the chvt(1) program will also be run.
-                       Any remaining output is taken as XAUTHORITY data.
-                       It can be either of the form XAUTHORITY=<file> or raw
-                       xauthority data for the display. For example;
-
-                            xauth extract - $DISPLAY"
-
-                       NOTE: As specified in the previous paragraph, you can
-                       supply your own WAIT:cmd=... program or script, BUT
-                       there are two very useful *BUILT-IN* ones: FINDDISPLAY
-                       (alias -find above) and FINDCREATEDISPLAY (alias -create
-                       above.)  Most people use these instead of creating
-                       their own script.  Read the following (especially the
-                       BUILT-IN modes sections) to see how to configure these
-                       two useful builtin -display WAIT: modes.
-
-                       In the case of -unixpw (and -unixpw_nis only if x11vnc
-                       is running as root), then the cmd= command is run
-                       as the user who just authenticated via the login and
-                       password prompt.
-
-                       In the case of -unixpw_cmd, the commands will also be
-                       run as the logged-in user, as long as the user-supplied
-                       helper program supports RFB_UNIXPW_CMD_RUN (see the
-                       -unixpw_cmd option.)
-
-                       Also in the case of -unixpw, the user logging in can
-                       place a colon at the end of her username and supply
-                       a few options: scale=, scale_cursor= (or sc=), solid
-                       (or so), id=, clear_mods (or cm), clear_keys (or
-                       ck), clear_all (or ca), repeat, speeds= (or sp=),
-                       readtimeout= (or rd=), viewonly (or vo), nodisplay=
-                       (or nd=), rotate= (or ro=), or noncache (or nc),
-                       all separated by commas if there is more than one.
-                       After the user logs in successfully, these options will
-                       be applied to the VNC screen.  For example,
-
-                          login: fred:scale=3/4,sc=1,repeat
-                          Password: ...
-
-                          login: runge:sp=modem,rd=120,solid
-
-                       for convenience m/n implies scale= e.g. fred:3/4  If you
-                       type and enter your password incorrectly, to retrieve
-                       your long "login:" line press the Up arrow once
-                       (before typing anything else).
-
-                       Most of these colon options only apply to the builtin
-                       FINDDISPLAY and FINDCREATEDISPLAY modes, but note
-                       that they are passed to the extrenal command in the
-                       environment as well and so could be used.
-
-                       In the login panel, press F1 to get a list of the
-                       available options that you can add after the username.
-
-                       Another option is "geom=WxH" or "geom=WxHxD" (or
-                       ge=). This only has an effect in FINDCREATEDISPLAY
-                       mode when a virtual X server such as Xvfb is going
-                       to be created.  It sets the width and height of
-                       the new display, and optionally the color depth as
-                       well.
-
-                       You can also supply "gnome", "kde", "twm",
-                       "fvwm", "mwm", "dtwm", "wmaker", "xfce",
-                       "lxde", "enlightenment", "Xsession", or
-                       "failsafe" (same as "xterm") to have the created
-                       display use that mode for the user session.
-
-                       Specify "tag=..." to set the unique FD_TAG desktop
-                       session tag described below.  Note: this option will
-                       be ignored if the FD_TAG env. var. is already set or
-                       if the viewer-side supplied value is not completely
-                       composed of alphanumeric or '_' or '-' characters.
-
-                       User preferences file: Instead of having the user type
-                       in geom=WxH,... etc. every time he logs in to find
-                       or create his X session, if you set FD_USERPREFS to
-                       a string that does not contain the "/" character,
-                       then the user's home directory is prepended to that
-                       string and if the file exists its first line is read
-                       and appended to any options he supplied at the login:
-                       prompt.  For example -env FD_USERPREFS=.x11vnc_create
-                       and the user put "geom=1600x1200" in his
-                       ~/.x11vnc_create file.
-
-                       To disable the option setting set the environment
-                       variable X11VNC_NO_UNIXPW_OPTS=1 before starting x11vnc.
-                       To set any other options, the user can use the gui
-                       (x11vnc -gui connect) or the remote control method
-                       (x11vnc -R opt:val) during his VNC session.
-
-                       So we see the combination of -display WAIT:cmd=... and
-                       -unixpw allows automatic pairing of an unix
-                       authenticated VNC user with his desktop.  This could
-                       be very useful on SunRays and also any system where
-                       multiple users share a given machine.  The user does
-                       not need to remember special ports or passwords set up
-                       for his desktop and VNC.
-
-                       A nice way to use WAIT:cmd=... is out of inetd(8)
-                       (it automatically forks a new x11vnc for each user).
-                       You can have the x11vnc inetd spawned process run as,
-                       say, root or nobody.  When run as root (for either inetd
-                       or display manager), you can also supply the option
-                       "-users unixpw=" to have the x11vnc process switch to
-                       the user as well.  Note: there will be a 2nd SSL helper
-                       process that will not switch, but it is only encoding
-                       and decoding the encrypted stream at that point.
-
-                       BUILT-IN modes:
-
-                       -- Automatic Finding of User X Sessions --
-
-                       As a special case, WAIT:cmd=FINDDISPLAY will run a
-                       script that works on most Unixes to determine a user's
-                       DISPLAY variable and xauthority data (see who(1)).
-
-                       NOTE: The option "-find" is an alias for this mode.
-
-                       To have this default script printed to stdout (e.g. for
-                       customization) run with WAIT:cmd=FINDDISPLAY-print To
-                       have the script run to print what display it would find
-                       use "-finddpy" or WAIT:cmd=FINDDISPLAY-run
-
-                       The standard script runs xdpyinfo(1) run on potential
-                       displays.  If your X server(s) have a login greeter
-                       that exclusively grabs the Xserver, then xdpyinfo
-                       blocks forever and this mode will not work.  See
-                       www.karlrunge.com/x11vnc/faq.html#faq-display-manager
-                       for how to disable this for dtgreet on Solaris and
-                       possibly for other greeters.
-
-                       In -find/cmd=FINDDISPLAY mode, if you set FD_XDM=1,
-                       e.g. 'x11vnc -env FD_XDM=1 -find ...' and x11vnc is
-                       running as root (e.g. inetd) then it will try to find
-                       the XAUTHORITY file of a running XDM/GDM/KDM login
-                       greeter (i.e. no user has logged into an X session yet.)
-
-                       As another special case, WAIT:cmd=HTTPONCE will allow
-                       x11vnc to service one http request and then exit.
-                       This is usually done in -inetd mode to run on, say,
-                       port 5800 and allow the Java vncviewer to be downloaded
-                       by client web browsers.  For example:
-
-                        5815 stream tcp nowait root /usr/sbin/tcpd /.../x11vnc
-\
-                          -inetd -q -http_ssl -prog /.../x11vnc \
-                          -display WAIT:cmd=HTTPONCE
-
-                       Where /.../x11vnc is the full path to x11vnc.
-                       It is used in the Apache SSL-portal example (see FAQ).
-
-                       In this mode you can set X11VNC_SKIP_DISPLAY to a
-                       comma separated list of displays (e.g. ":0,:1") to
-                       ignore in the finding process.  The ":" is optional.
-                       Ranges n-m e.g. 0-20 can also be supplied. This string
-                       can also be set by the connecting user via "nd="
-                       using "+" instead of ","  If "nd=all" or you set
-                       X11VNC_SKIP_DISPLAY=all then all display finding fails
-                       as if you set X11VNC_FINDDISPLAY_ALWAYS_FAILS=1 (below.)
-
-                       On some systems lsof(1) can be very slow.  Set the
-                       env. var. FIND_DISPLAY_NO_LSOF=1 to skip using lsof to
-                       try to find the Linux VT the X server is running on.
-                       set FIND_DISPLAY_NO_VT_FIND=1 to avoid looking at all.
-
-                       -- Automatic Creation of User X Sessions --
-
-                       An interesting option is WAIT:cmd=FINDCREATEDISPLAY
-                       that is like FINDDISPLAY in that is uses the same method
-                       to find an existing display.  However, if it does not
-                       find one it will try to *start* up an X server session
-                       for the user.  This is the only time x11vnc tries to
-                       actually start up an X server.
-
-                       NOTE: The option "-create" is an alias for this mode.
-
-                       It will start looking for an open display number at :20
-                       Override via X11VNC_CREATE_STARTING_DISPLAY_NUMBER=n
-                       By default 80 X displays are allowed (i.e. going to :99)
-                       Override via X11VNC_CREATE_MAX_DISPLAYS=n
-
-                       For its heuristics, the create display script sets
-                       LC_ALL=C so that command output is uniform.  By default
-                       it will try to restore LC_ALL right before starting the
-                       user session.  However, if you don't mind it keeping
-                       LC_ALL=C set the env. var.: X11VNC_CREATE_LC_ALL_C_OK=1
-
-                       By default FINDCREATEDISPLAY will try Xvfb and then
-                       Xdummy:
-
-                       The Xdummy wrapper is part of the x11vnc source code
-                       (x11vnc/misc/Xdummy)  It should be available in PATH
-                       and have run "Xdummy -install" once to create the
-                       shared library.  Xdummy only works on Linux.  As of
-                       12/2009 it no longer needs to be run as root, and the
-                       default is to not run as root.  In some circumstances
-                       permissions may require running it as root, in these
-                       cases specify FD_XDUMMY_RUN_AS_ROOT=1, this is the same
-                       as supplying -root to the Xdummy cmdline.
-
-                       Xvfb is available on most platforms and does not
-                       require root.
-
-                       An advantage of Xdummy over Xvfb is that Xdummy supports
-                       RANDR dynamic screen resizing.
-
-                       When x11vnc exits (i.e. user disconnects) the X
-                       server session stays running in the background.
-                       The FINDDISPLAY will find it directly next time.
-                       The user must exit the X session in the usual way for
-                       it to terminate (or kill the X server process if all
-                       else fails).
-
-                       To troubleshoot the FINDCREATEDISPLAY mechanism,
-                       set the following env. var. to an output log file,
-                       e.g -env CREATE_DISPLAY_OUTPUT=/tmp/mydebug.txt
-
-                       So this is a somewhat odd mode for x11vnc in that it
-                       will start up and poll virtual X servers!  This can
-                       be used from, say, inetd(8) to provide a means of
-                       definitely getting a desktop (either real or virtual)
-                       on the machine.  E.g. a desktop service:
-
-                         5900 stream tcp nowait root /usr/sbin/tcpd /.../x11vnc
-                          -inetd -q -http -ssl SAVE -unixpw -users unixpw=\
-                          -passwd secret -prog /.../x11vnc \
-                          -display WAIT:cmd=FINDCREATEDISPLAY
-
-                       Where /.../x11vnc is the full path to x11vnc.
-
-                       See the -svc/-service option alias above.
-
-                       If for some reason you do not want x11vnc to ever
-                       try to find an existing display set the env. var
-                       X11VNC_FINDDISPLAY_ALWAYS_FAILS=1 (also -env ...)
-                       This is the same as setting X11VNC_SKIP_DISPLAY=all or
-                       supplying "nd=all" after "username:"
-
-                       Use WAIT:cmd=FINDCREATEDISPLAY-print to print out the
-                       script that is used for this.
-
-                       You can specify the preferred X server order via e.g.,
-                       WAIT:cmd=FINDCREATEDISPLAY-Xdummy,Xvfb,X  and/or leave
-                       out ones you do not want.  The the case "X" means try
-                       to start up a real, hardware X server using xinit(1)
-                       or startx(1).  If there is already an X server running
-                       the X case may only work on Linux (see startx(1)).
-
-                       "Xvnc" will start up a VNC X server (real-
-                       or tight-vnc, e.g. use if Xvfb is not available).
-                       "Xsrv" will start up the server program in the
-                       variable "FD_XSRV" if it is non-empty. You can make
-                       this be a wrapper script if you like (it must handle :N,
-                       -geometry, and -depth and other X server options).
-
-                       You can set the environment variable FD_GEOM (or
-                       X11VNC_CREATE_GEOM) to WxH or WxHxD to set the width
-                       and height and optionally the color depth of the
-                       created display.  You can also set FD_SESS to be the
-                       session (short name of the windowmanager: kde, gnome,
-                       twm, failsafe, etc.). FD_OPTS contains extra options
-                       to pass to the X server. You can also set FD_PROG to
-                       be the full path to the session/windowmanager program.
-
-                       More FD tricks:  FD_CUPS=port or FD_CUPS=host:port
-                       will set the cups printing environment.  Similarly for
-                       FD_ESD=port or FD_ESD=host:port for esddsp sound
-                       redirection.  Set FD_EXTRA to a command to be run a
-                       few seconds after the X server starts up.  Set FD_TAG
-                       to be a unique name for the session, it is set as an
-                       X property, that makes FINDDISPLAY only find sessions
-                       with that tag value.
-
-                       Set FD_XDMCP_IF to the network interface that the
-                       display manager is running on; default is 'localhost'
-                       but you may need to set it to '::1' on some IPv6 only
-                       systems or misconfigured display managers.
-
-                       If you want the FINDCREATEDISPLAY session to contact an
-                       XDMCP login manager (xdm/gdm/kdm) on the same machine,
-                       then use "Xvfb.xdmcp" instead of "Xvfb", etc.
-                       The user will have to supply his username and password
-                       one more time (but he gets to select his desktop type
-                       so that can be useful).  For this to work, you will
-                       need to enable localhost XDMCP (udp port 177) for the
-                       display manager.  This seems to be:
-
-                        for gdm in gdm.conf:   Enable=true in section [xdmcp]
-                        for kdm in kdmrc:      Enable=true in section [Xdmcp]
-                        for xdm in xdm-config: DisplayManager.requestPort: 177
-
-                       See the shorthand options above "-svc", "-xdmsvc"
-                       and "-sshxdmsvc" that specify the above options for
-                       some useful cases.
-
-                       If you set the env. var WAITBG=1 x11vnc will go into
-                       the background once listening in wait mode.
-
-                       Another special mode is FINDCREATEDISPLAY-Xvnc.redirect,
-                       (or FINDDISPLAY-Xvnc.redirect).  In this case it will
-                       start up Xvnc as above if needed, but instead of
-                       polling it in its normal way, it simply does a socket
-                       redirection of the connected VNC viewer to the Xvnc.
-
-                       So in Xvnc.redirect x11vnc does no VNC but merely
-                       transfers the data back and forth.  This should be
-                       faster then x11vnc's polling method, but not as fast
-                       as connecting directly to the Xvnc with the VNC Viewer.
-                       The idea here is to take advantage of x11vnc's display
-                       finding/creating scheme, SSL, and perhaps a few others.
-                       Most of x11vnc's options do not apply in this mode.
-
-                       Xvnc.redirect should also work for the vnc.so X server
-                       module for the h/w display however it will work only
-                       for finding the display and the user must already be
-                       logged into the X console.
-
--vencrypt mode         The VeNCrypt extension to the VNC protocol allows
-                       encrypted SSL/TLS connections.  If the -ssl mode is
-                       enabled, then VeNCrypt is enabled as well BY DEFAULT
-                       (they both use a SSL/TLS tunnel, only the protocol
-                       handshake is a little different.)
-
-                       To control when and how VeNCrypt is used, specify the
-                       mode string.  If mode is "never", then VeNCrypt is
-                       not used.  If mode is "support" (the default) then
-                       VeNCrypt is supported.  If mode is "only", then the
-                       similar and older ANONTLS protocol is not simultaneously
-                       supported.  x11vnc's normal SSL mode (vncs://) will be
-                       supported under -ssl unless you set mode to "force".
-
-                       If mode is prefixed with "nodh:", then Diffie Hellman
-                       anonymous key exchange is disabled.  If mode is prefixed
-                       with "nox509:", then X509 key exchange is disabled.
-
-                       To disable all Anonymous Diffie-Hellman access
-                       (susceptible to Man-In-The-Middle attack) you will need
-                       to supply "-vencrypt nodh:support -anontls never"
-                       or "-vencrypt nodh:only"
-
-                       If mode is prefixed with "newdh:", then new Diffie
-                       Hellman parameters are generated for each connection
-                       (this can be time consuming: 1-60 secs; see -dhparams
-                       below for a faster way) rather than using the
-                       fixed values in the program.  Using fixed, publicly
-                       known values is not known to be a security problem.
-                       This setting applies to ANONTLS as well.
-
-                       Long example: -vencrypt newdh:nox509:support
-
-                       Also, if mode is prefixed with "plain:", then
-                       if -unixpw mode is active the VeNCrypt "*Plain"
-                       username+passwd method is enabled for Unix logins.
-                       Otherwise in -unixpw mode the normal login panel is
-                       provided.
-
-                       You *MUST* supply the -ssl option for VeNCrypt to
-                       be active.  The -vencrypt option only fine-tunes its
-                       operation.
-
--anontls mode          The ANONTLS extension to the VNC protocol allows
-                       encrypted SSL/TLS connections.  If the -ssl mode is
-                       enabled, then ANONTLS is enabled as well BY DEFAULT
-                       (they both use a SSL/TLS tunnel, only the protocol
-                       handshake is a little different.)
-
-                       ANONTLS is an older SSL/TLS mode introduced by vino.
-
-                       It is referred to as 'TLS' for its registered VNC
-                       security-type name, but we use the more descriptive
-                       'ANONTLS' here because it provides only Anonymous
-                       Diffie-Hellman encrypted connections, and hence no
-                       possibility for certificate authentication.
-
-                       To control when and how ANONTLS is used, specify the
-                       mode string.  If mode is "never", then ANONTLS is not
-                       used.  If mode is "support" (the default) then ANONTLS
-                       is supported.  If mode is "only", then the similar
-                       VeNCrypt protocol is not simultaneously supported.
-                       x11vnc's normal SSL mode (vncs://) will be supported
-                       under -ssl unless you set mode to "force".
-
-                       If mode is prefixed with "newdh:", then new Diffie
-                       Hellman parameters are generated for each connection
-                       (this can be time consuming: 1-60 secs; see -dhparams
-                       below for a faster way) rather than using the
-                       fixed values in the program.  Using fixed, publicly
-                       known values is not known to be a security problem.
-                       This setting applies to VeNCrypt as well.  See the
-                       description of "plain:" under -vencrypt.
-
-                       Long example: -anontls newdh:plain:support
-
-                       You *MUST* supply the -ssl option for ANONTLS to
-                       be active.  The -anontls option only fine-tunes its
-                       operation.
-
--sslonly               Same as: "-vencrypt never -anontls never"  i.e. it
-                       disables the VeNCrypt and ANONTLS encryption methods
-                       and only allows standard SSL tunneling.  You must also
-                       supply the -ssl ... option (see below.)
-
-
--dhparams file         For some operations a set of Diffie Hellman parameters
-                       (prime and generator) is needed.  If so, use the
-                       parameters in "file". In particular, the VeNCrypt and
-                       ANONTLS anonymous DH mode need them.  By default a
-                       fixed set is used. If you do not want to do that you
-                       can specify "newdh:" to the -vencrypt and -anontls
-                       options to generate a new set each session.  If that
-                       is too slow for you, use -dhparams file to a set you
-                       created manually via "openssl dhparam -out file 1024"
-
--nossl                 Disable the -ssl option (see below). Since -ssl is off
-                       by default -nossl would only be used on the commandline
-                       to unset any *earlier* -ssl option (or -svc...)
-
--ssl [pem]             Use the openssl library (www.openssl.org) to provide a
-                       built-in encrypted SSL/TLS tunnel between VNC viewers
-                       and x11vnc.  This requires libssl support to be
-                       compiled into x11vnc at build time.  If x11vnc is not
-                       built with libssl support it will exit immediately when
-                       -ssl is prescribed.  See the -stunnel option below for
-                       an alternative.
-
-                       The VNC Viewer-side needs to support SSL/TLS as well.
-                       See this URL and also the discussion below for
-                       ideas on how to enable SSL support for the viewer:
-                       http://www.karlrunge.com/x11vnc/faq.html#faq-ssl-tun
-                       nel-viewers .  x11vnc provides an SSL enabled Java
-                       viewer applet in the classes/ssl directory (-http or
-                       -httpdir options.)  The SSVNC viewer package supports
-                       SSL tunnels too.
-
-                       If the VNC Viewer supports VeNCrypt or ANONTLS (vino's
-                       encryption mode) they are also supported by the -ssl
-                       mode (see the -vencrypt and -anontls options for more
-                       info; use -sslonly to disable both of them.)
-
-                       Use "-ssl /path/to/mycert.pem" to specify an SSL
-                       certificate file in PEM format to use to identify and
-                       provide a key for this server.  See openssl(1) for more
-                       info about PEMs and the -sslGenCert and "-ssl SAVE"
-                       options below for how to create them.
-
-                       The connecting VNC viewer SSL tunnel can (at its option)
-                       authenticate this server if it has the public key part
-                       of the certificate (or a common certificate authority,
-                       CA, is a more sophisticated way to verify this server's
-                       cert, see -sslGenCA below).  This authentication is
-                       done to prevent Man-In-The-Middle attacks.  Otherwise,
-                       if the VNC viewer simply accepts this server's key
-                       WITHOUT verification, the traffic is protected from
-                       passive sniffing on the network, but *NOT* from
-                       Man-In-The-Middle attacks. There are hacker tools
-                       like dsniff/webmitm and cain that implement SSL
-                       Man-In-The-Middle attacks.
-
-                       If [pem] is empty or the string "SAVE" then the
-                       openssl(1) command must be available to generate the
-                       certificate the first time.  A self-signed certificate
-                       is generated (see -sslGenCA and -sslGenCert for use
-                       of a Certificate Authority.)  It will be saved to the
-                       file ~/.vnc/certs/server.pem.  On subsequent calls if
-                       that file already exists it will be used directly.
-
-                       Use "SAVE_NOPROMPT" to avoid being prompted to
-                       protect the generated key with a passphrase.  However in
-                       -inetd and -bg modes there will be no prompting for a
-                       passphrase in either case.
-
-                       If [pem] is "SAVE_PROMPT" the server.pem certificate
-                       will be created based on your answers to its prompts for
-                       all info such as OrganizationalName, CommonName, etc.
-
-                       Use "SAVE-<string>" and "SAVE_PROMPT-<string>"
-                       to refer to the file ~/.vnc/certs/server-<string>.pem
-                       instead (it will be generated if it does not already
-                       exist).  E.g. "SAVE-charlie" will store to the file
-                       ~/.vnc/certs/server-charlie.pem
-
-                       Examples: x11vnc -ssl SAVE -display :0 ...
-                                 x11vnc -ssl SAVE-someother -display :0 ...
-
-                       If [pem] is "TMP" and the openssl(1) utility
-                       command exists in PATH, then a temporary, self-signed
-                       certificate will be generated for this session.  If
-                       openssl(1) cannot be used to generate a temporary
-                       certificate x11vnc exits immediately.  The temporary
-                       cert will be discarded when x11vnc exits.
-
-                       If successful in using openssl(1) to generate a
-                       temporary certificate in "SAVE" or "TMP" creation
-                       modes, the public part of it will be displayed to stderr
-                       (e.g. one could copy it to the client-side to provide
-                       authentication of the server to VNC viewers.)
-
-                       NOTE: In "TMP" mode, unless you safely copy the
-                       public part of the temporary Cert to the viewer for
-                       authenticate *every time* (unlikely...), then only
-                       passive sniffing attacks are prevented and you are
-                       still open to Man-In-The-Middle attacks.  This is
-                       why the default "SAVE" mode is preferred (and more
-                       sophisticated CA mode too).  Only with saved keys AND
-                       the VNC viewer authenticating them (via the public
-                       certificate), are Man-In-The-Middle attacks prevented.
-
-                       If [pem] is "ANON" then the Diffie-Hellman anonymous
-                       key exchange method is used.  In this mode there
-                       are *no* SSL certificates and so it is not possible
-                       to authenticate either the VNC server or VNC client.
-                       Thus only passive network sniffing attacks are avoided:
-                       the "ANON" method is susceptible to Man-In-The-Middle
-                       attacks.  "ANON" is not recommended; instead use
-                       a SSL PEM you created or the default "SAVE" method.
-
-                       See -ssldir below to use a directory besides the
-                       default ~/.vnc/certs
-
-                       If your x11vnc binary was not compiled with OpenSSL
-                       library support, use of the -ssl option will induce an
-                       immediate failure and exit.  For such binaries, consider
-                       using the -stunnel option for SSL encrypted connections.
-
-                       Misc Info: In temporary cert creation mode "TMP", set
-                       the env. var. X11VNC_SHOW_TMP_PEM=1 to have x11vnc print
-                       out the entire certificate, including the PRIVATE KEY
-                       part, to stderr.  There are better ways to get/save this
-                       info.  See "SAVE" above and "-sslGenCert" below.
-
--ssltimeout n          Set SSL read timeout to n seconds.  In some situations
-                       (i.e. an iconified viewer in Windows) the viewer stops
-                       talking and the connection is dropped after the default
-                       timeout (25s for about the first minute, 43200s later).
-                       Set to zero to poll forever.  Set to a negative value
-                       to use the builtin setting.
-
-                       Note that this value does NOT apply to the *initial* ssl
-                       init connection.  The default timeout for that is 20sec.
-                       Use -env SSL_INIT_TIMEOUT=n to modify it.
-
--sslnofail             Exit at the first SSL connection failure. Useful when
-                       scripting SSL connections (e.g. x11vnc is started via
-                       ssh) and you do not want x11vnc waiting around for more
-                       connections, tying up ports, etc.
-
--ssldir dir            Use "dir" as an alternate ssl certificate and key
-                       management toplevel directory.  The default is
-                       ~/.vnc/certs
-
-                       This directory is used to store server and other
-                       certificates and keys and also other materials.  E.g. in
-                       the simplest case, "-ssl SAVE" will store the x11vnc
-                       server cert in dir/server.pem
-
-                       Use of alternate directories via -ssldir allows you to
-                       manage multiple VNC Certificate Authority (CA) keys.
-                       Another use is if ~/.vnc/cert is on an NFS share you
-                       might want your certificates and keys to be on a local
-                       filesystem to prevent network snooping (for example
-                       -ssldir /var/lib/x11vnc-certs).
-
-                       -ssldir affects nearly all of the other -ssl* options,
-                       e.g. -ssl SAVE, -sslGenCert, etc..
-
--sslverify path        For either of the -ssl or -stunnel modes, use "path"
-                       to provide certificates to authenticate incoming VNC
-                       *Client* connections (normally only the server is
-                       authenticated in SSL.)  This can be used as a method
-                       to replace standard password authentication of clients.
-
-                       If "path" is a directory it contains the client (or CA)
-                       certificates in separate files.  If path is a file,
-                       it contains one or more certificates. See special tokens
-                       below.  These correspond to the "CApath = dir" and
-                       "CAfile = file" stunnel options.  See the stunnel(8)
-                       manpage for details.
-
-                       Examples:
-                              x11vnc -ssl -sslverify ~/my.crt
-                              x11vnc -ssl -sslverify ~/my_pem_dir/
-
-                       Note that if path is a directory, it must contain
-                       the certs in separate files named like <HASH>.0, where
-                       the value of <HASH> is found by running the command
-                       "openssl x509 -hash -noout -in file.crt". Evidently
-                       one uses <HASH>.1 if there is a collision...
-
-                       The the key-management utility "-sslCertInfo HASHON"
-                       and "-sslCertInfo HASHOFF" will create/delete these
-                       hashes for you automatically (via symlink) in the HASH
-                       subdirs it manages.  Then you can point -sslverify to
-                       the HASH subdir.
-
-                       Special tokens: in -ssl mode, if "path" is not a file or
-                       a directory, it is taken as a comma separated list of
-                       tokens that are interpreted as follows:
-
-                       If a token is "CA" that means load the CA/cacert.pem
-                       file from the ssl directory.  If a token is "clients"
-                       then all the files clients/*.crt in the ssl directory
-                       are loaded.  Otherwise the file clients/token.crt
-                       is attempted to be loaded.  As a kludge, use a token
-                       like ../server-foo to load a server cert if you find
-                       that necessary.
-
-                       Use -ssldir to use a directory different from the
-                       ~/.vnc/certs default.
-
-                       Note that if the "CA" cert is loaded you do not need
-                       to load any of the certs that have been signed by it.
-                       You will need to load any additional self-signed certs
-                       however.
-
-                       Examples:
-                              x11vnc -ssl -sslverify CA
-                              x11vnc -ssl -sslverify self:fred,self:jim
-                              x11vnc -ssl -sslverify CA,clients
-
-                       Usually "-sslverify CA" is the most effective.
-                       See the -sslGenCA and -sslGenCert options below for
-                       how to set up and manage the CA framework.
-
-
-
-                       NOTE: the following utilities, -sslGenCA, -sslGenCert,
-                       -sslEncKey, -sslCertInfo, and -sslCRL are provided for
-                       completeness, but for casual usage they are overkill.
-
-                       They provide VNC Certificate Authority (CA) key creation
-                       and server / client key generation and signing.  So they
-                       provide a basic Public Key management framework for
-                       VNC-ing with x11vnc. (note that they require openssl(1)
-                       be installed on the system)
-
-                       However, the simplest usage mode, "-ssl TMP" (where
-                       x11vnc automatically generates its own, self-signed,
-                       temporary key and the VNC viewers always accept it,
-                       e.g. accepting via a dialog box) is probably safe enough
-                       for most scenarios.  CA management is not needed.
-
-                       To protect against Man-In-The-Middle attacks the "TMP"
-                       mode can be improved by using "-ssl SAVE" (same as
-                       "-ssl", i.e. the default) to have x11vnc create a
-                       longer term self-signed certificate, and then (safely)
-                       copy the corresponding public key cert to the desired
-                       client machines (care must be taken the private key part
-                       is not stolen; you will be prompted for a passphrase).
-
-                       So keep in mind no CA key creation or management
-                       (-sslGenCA and -sslGenCert) is needed for either of
-                       the above two common usage modes.
-
-                       One might want to use -sslGenCA and -sslGenCert
-                       if you had a large number of VNC client and server
-                       workstations.  That way the administrator could generate
-                       a single CA key with -sslGenCA and distribute its
-                       certificate part to all of the workstations.
-
-                       Next, he could create signed VNC server keys
-                       (-sslGenCert server ...) for each workstation or user
-                       that then x11vnc would use to authenticate itself to
-                       any VNC client that has the CA cert.
-
-                       Optionally, the admin could also make it so the
-                       VNC clients themselves are authenticated to x11vnc
-                       (-sslGenCert client ...)  For this -sslverify would be
-                       pointed to the CA cert (and/or self-signed certs).
-
-                       x11vnc will be able to use all of these cert and
-                       key files.  On the VNC client side, they will need to
-                       be "imported" somehow.  Web browsers have "Manage
-                       Certificates" actions as does the Java applet plugin
-                       Control Panel.  stunnel can also use these files (see
-                       the ss_vncviewer example script in the FAQ and SSVNC.)
-
--sslCRL path           Set the Certificate Revocation Lists (CRL) to "path".
-                       This setting applies for both -ssl and -stunnel modes.
-
-                       If path is a file, the file contains one or more CRLs
-                       in PEM format.  If path is a directory, it contains
-                       hash named files of CRLs in the usual OpenSSL manner.
-                       See the OpenSSL and stunnel(8) documentation for
-                       more info.
-
-                       This option only applies if -sslverify has been
-                       supplied: it checks for revocation along the
-                       certificate chain used to verify the VNC client.
-                       The -sslCRL setting will be ignored when -sslverify is
-                       not specified.
-
-                       Note that if a CRL's expiration date has passed, all
-                       SSL connections will fail regardless of if they are
-                       related to the subject of the CRL or not.
-
-                       Only rarely will one's x11vnc -ssl infrastructure be so
-                       large that this option would be useful (since normally
-                       maintaining the contents of the -sslverify file or
-                       directory should be enough.)  However, when using
-                       x11vnc with a Certificate Authority (see -sslGenCA)
-                       to authenticate Clients via SSL/TLS, the -sslCRL option
-                       can be useful to revoke users' certs whose private SSL
-                       keys were lost or stolen (e.g. laptop.)  This way a new
-                       CA cert+key does not need to be created and new signed
-                       client keys generated and distributed to all users.
-
-                       To create a CRL file with revoked certificates the
-                       commands 'openssl ca -revoke ...' and 'openssl ca
-                       -gencrl ...' are useful.  (Run them in ~/.vnc/certs)
-
--sslGenCA [dir]        Generate your own Certificate Authority private key,
-                       certificate, and other files in directory [dir].
-                       x11vnc then exits.
-
-                       If [dir] is not supplied, a -ssldir setting is used,
-                       or otherwise ~/.vnc/certs is used.
-
-                       This command also creates directories where server and
-                       client certs and keys will be stored.  The openssl(1)
-                       program must be installed on the system and available
-                       in PATH.
-
-                       After the CA files and directories are created the
-                       x11vnc command exits; the VNC server is not run.
-
-                       You will be prompted for information to put into the CA
-                       certificate.  The info does not have to be accurate just
-                       as long as clients accept the cert for VNC connections.
-                       You will also need to supply a passphrase of at least
-                       4 characters for the CA private key.
-
-                       Once you have generated the CA you can distribute
-                       its certificate part, [dir]/CA/cacert.pem, to other
-                       workstations where VNC viewers will be run.  One will
-                       need to "import" this certificate in the applications,
-                       e.g. Web browser, Java applet plugin, stunnel, etc.
-                       Next, you can create and sign keys using the CA with
-                       the -sslGenCert option below.
-
-                       Examples:
-                                x11vnc -sslGenCA
-                                x11vnc -sslGenCA  ~/myCAdir
-                                x11vnc -ssldir ~/myCAdir -sslGenCA
-
-                       (the last two lines are equivalent)
-
--sslGenCert type name  Generate a VNC server or client certificate and private
-                       key pair signed by the CA created previously with
-                       -sslGenCA.  The openssl(1) program must be installed
-                       on the system and available in PATH.
-
-                       After the Certificate is generated x11vnc exits; the
-                       VNC server is not run.
-
-                       The type of key to be generated is the string "type".
-                       It is either "server" (i.e. for use by x11vnc) or
-                       "client" (for a VNC viewer).  Note that typically
-                       only "server" is used: the VNC clients authenticate
-                       themselves by a non-public-key method (e.g. VNC or
-                       unix password).  "type" is required.
-
-                       An arbitrary default name you want to associate with
-                       the key is supplied by the "name" string.  You can
-                       change it at the various prompts when creating the key.
-                       "name" is optional.
-
-                       If name is left blank for clients keys then "nobody"
-                       is used.  If left blank for server keys, then the
-                       primary server key: "server.pem" is created (this
-                       is the saved one referenced by "-ssl SAVE" when the
-                       server is started)
-
-                       If "name" begins with the string "self:" then
-                       a self-signed certificate is created instead of one
-                       signed by your CA key.
-
-                       If "name" begins with the string "req:" then only a
-                       key (.key) and a certificate signing *request* (.req)
-                       are generated.  You can then send the .req file to
-                       an external CA (even a professional one, e.g. Thawte)
-                       and then combine the .key and the received cert into
-                       the .pem file with the same basename.
-
-                       The distinction between "server" and "client" is
-                       simply the choice of output filenames and sub-directory.
-                       This makes it so the -ssl SAVE-name option can easily
-                       pick up the x11vnc PEM file this option generates.
-                       And similarly makes it easy for the -sslverify option
-                       to pick up your client certs.
-
-                       There is nothing special about the filename or directory
-                       location of either the "server" and "client" certs.
-                       You can rename the files or move them to wherever
-                       you like.
-
-                       Precede this option with -ssldir [dir] to use a
-                       directory other than the default ~/.vnc/certs You will
-                       need to run -sslGenCA on that directory first before
-                       doing any -sslGenCert key creation.
-
-                       Note you cannot recreate a cert with exactly the same
-                       distiguished name (DN) as an existing one.  To do so,
-                       you will need to edit the [dir]/CA/index.txt file to
-                       delete the line.
-
-                       Similar to -sslGenCA, you will be prompted to fill
-                       in some information that will be recorded in the
-                       certificate when it is created.
-
-                       Tip: if you know the fully-qualified hostname other
-                       people will be connecting to, you can use that as the
-                       CommonName "CN" to avoid some applications (e.g. web
-                       browsers and java plugin) complaining that it does not
-                       match the hostname.
-
-                       You will also need to supply the CA private key
-                       passphrase to unlock the private key created from
-                       -sslGenCA.  This private key is used to sign the server
-                       or client certificate.
-
-                       The "server" certs can be used by x11vnc directly by
-                       pointing to them via the -ssl [pem] option.  The default
-                       file will be ~/.vnc/certs/server.pem.  This one would
-                       be used by simply typing -ssl SAVE.  The pem file
-                       contains both the certificate and the private key.
-                       server.crt file contains the cert only.
-
-                       The "client" cert + private key file will need
-                       to be copied and imported into the VNC viewer
-                       side applications (Web browser, Java plugin,
-                       stunnel, etc.)  Once that is done you can delete the
-                       "client" private key file on this machine since
-                       it is only needed on the VNC viewer side.  The,
-                       e.g. ~/.vnc/certs/clients/<name>.pem contains both
-                       the cert and private key.  The <name>.crt contains the
-                       certificate only.
-
-                       NOTE: It is very important to know one should
-                       generate new keys with a passphrase.  Otherwise if an
-                       untrusted user steals the key file he could use it to
-                       masquerade as the x11vnc server (or VNC viewer client).
-                       You will be prompted whether to encrypt the key with
-                       a passphrase or not.  It is recommended that you do.
-                       One inconvenience to a passphrase is that it must
-                       be typed in EVERY time x11vnc or the client app is
-                       started up.
-
-                       Examples:
-
-                               x11vnc -sslGenCert server
-                               x11vnc -ssl SAVE -display :0 ...
-
-                       and then on viewer using ss_vncviewer stunnel wrapper
-                       (see the FAQ):
-                               ss_vncviewer -verify ./cacert.crt hostname:0
-
-                       (this assumes the cacert.crt cert from -sslGenCA
-                       was safely copied to the VNC viewer machine where
-                       ss_vncviewer is run)
-
-                       Example using a name:
-
-                               x11vnc -sslGenCert server charlie
-                               x11vnc -ssl SAVE-charlie -display :0 ...
-
-                       Example for a client certificate (rarely used):
-
-                               x11vnc -sslGenCert client roger
-                               scp ~/.vnc/certs/clients/roger.pem somehost:.
-                               rm  ~/.vnc/certs/clients/roger.pem
-
-                       x11vnc is then started with the option -sslverify
-                       ~/.vnc/certs/clients/roger.crt (or simply -sslverify
-                       roger), and on the viewer user on somehost could do
-                       for example:
-
-                               ss_vncviewer -mycert ./roger.pem hostname:0
-
-                       If you set the env. var REQ_ARGS='...' it will be
-                       passed to openssl req(1).  A common use would be
-                       REQ_ARGS='-days 1095' to bump up the expiration date
-                       (3 years in this case).
-
--sslEncKey pem         Utility to encrypt an existing PEM file with a
-                       passphrase you supply when prompted.  For that key to be
-                       used (e.g. by x11vnc) the passphrase must be supplied
-                       each time.
-
-                       The "SAVE" notation described under -ssl applies as
-                       well. (precede this option with -ssldir [dir] to refer
-                       a directory besides the default ~/.vnc/certs)
-
-                       The openssl(1) program must be installed on the system
-                       and available in PATH.  After the Key file is encrypted
-                       the x11vnc command exits; the VNC server is not run.
-
-                       Examples:
-                               x11vnc -sslEncKey /path/to/foo.pem
-                               x11vnc -sslEncKey SAVE
-                               x11vnc -sslEncKey SAVE-charlie
-
--sslCertInfo pem       Prints out information about an existing PEM file.
-                       In addition the public certificate is also printed.
-                       The openssl(1) program must be in PATH. Basically the
-                       command "openssl x509 -text" is run on the pem.
-
-                       After the info is printed the x11vnc command exits;
-                       the VNC server is not run.
-
-                       The "SAVE" notation described under -ssl applies
-                       as well.
-
-                       Using  "LIST" will give a list of all certs being
-                       managed (in the ~/.vnc/certs dir, use -ssldir to refer
-                       to another dir).  "ALL" will print out the info for
-                       every managed key (this can be very long).  Giving a
-                       client or server cert shortname will also try a lookup
-                       (e.g. -sslCertInfo charlie).  Use "LISTL" or "LL"
-                       for a long (ls -l style) listing.
-
-                       Using "HASHON" will create subdirs [dir]/HASH and
-                       [dir]/HASH with OpenSSL hash filenames (e.g. 0d5fbbf1.0)
-                       symlinks pointing up to the corresponding *.crt file.
-                       ([dir] is ~/.vnc/certs or one given by -ssldir.)
-                       This is a useful way for other OpenSSL applications
-                       (e.g. stunnel) to access all of the certs without
-                       having to concatenate them.  x11vnc will not use them
-                       unless you specifically reference them.  "HASHOFF"
-                       removes these HASH subdirs.
-
-                       The LIST, LISTL, LL, ALL, HASHON, HASHOFF words can
-                       also be lowercase, e.g. "list".
-
--sslDelCert pem        Prompts you to delete all .crt .pem .key .req files
-                       associated with [pem].  x11vnc then exits. "SAVE"
-                       and lookups as in -sslCertInfo apply as well.
-
--sslScripts            Prints out both the 'genCA' and 'genCert' x11vnc
-                       openssl wrapper scripts for you to examine, modify, etc.
-                       The scripts are printed to stdout and then the x11vnc
-                       program exits.
-
-
--stunnel [pem]         Use the stunnel(8) (stunnel.mirt.net) to provide an
-                       encrypted SSL tunnel between viewers and x11vnc.
-
-                       This external tunnel method was implemented prior to the
-                       integrated -ssl encryption described above.  It still
-                       works well and avoids the requirement of linking with
-                       the OpenSSL libraries.  This mode requires stunnel
-                       to be installed on the system and available via PATH
-                       (n.b. stunnel is often installed in sbin directories).
-                       Version 4.x of stunnel is assumed (but see -stunnel3
-                       below.)
-
-                       [pem] is optional, use "-stunnel /path/to/stunnel.pem"
-                       to specify a PEM certificate file to pass to stunnel.
-                       See the -ssl option for more info on certificate files.
-
-                       Whether or not your stunnel has its own certificate
-                       depends on your stunnel configuration; stunnel often
-                       generates one at install time.  See your stunnel
-                       documentation for details.  In any event, if you want to
-                       use this certificate you must supply the full path to it
-                       as [pem].  Note: the file may only be readable by root.
-
-                       [pem] may also be the special strings "TMP", "SAVE",
-                       and "SAVE..." as described in the -ssl option.
-                       If [pem] is not supplied, "SAVE" is assumed.
-
-                       Note that the VeNCrypt, ANONTLS, and "ANON" modes
-                       are not supported in -stunnel mode.
-
-                       stunnel is started up as a child process of x11vnc and
-                       any SSL connections stunnel receives are decrypted and
-                       sent to x11vnc over a local socket.  The strings
-                       "The SSL VNC desktop is ..." and "SSLPORT=..."
-                       are printed out at startup to indicate this.
-
-                       The -localhost option is enforced by default to avoid
-                       people routing around the SSL channel.  Use -env
-                       STUNNEL_DISABLE_LOCALHOST=1 to disable this security
-                       requirement.
-
-                       Set -env STUNNEL_DEBUG=1 for more debugging printout.
-
-                       Set -env STUNNEL_PROG=xxx to the full path of stunnel
-                       program you want to be used (e.g. /usr/bin/stunnel4).
-
-                       Set -env STUNNEL_LISTEN=xxx to the address of the
-                       network interface to listen on (the default is to listen
-                       on all interfaces), e.g. STUNNEL_LISTEN=192.168.1.100.
-
-                       A simple way to add IPv6 support is STUNNEL_LISTEN=::
-
-                       Your VNC viewer will also need to be able to connect
-                       via SSL.  Unfortunately not too many do this.  See the
-                       information about SSL viewers under the -ssl option.
-                       The x11vnc project's SSVNC is an option.
-
-                       Also, in the x11vnc distribution, patched TightVNC
-                       and UltraVNC Java applet jar files are provided in
-                       the classes/ssl directory that do SSL connections.
-                       Enable serving them with the -http, -http_ssl, or
-                       -httpdir (see the option descriptions for more info.)
-
-                       Note that for the Java viewer applet usage the
-                       "?PORT=xxxx" in the various URLs printed at startup
-                       will need to be supplied to the web browser to connect
-                       properly.
-
-                       Currently the automatic "single port" HTTPS mode of
-                       -ssl is not fully supported in -stunnel mode.  However,
-                       it can be emulated via:
-
-                         % x11vnc -stunnel -http_ssl -http_oneport ...
-
-                       In general, it is also not too difficult to set up
-                       an stunnel or other SSL tunnel on the viewer side.
-                       A simple example on Unix using stunnel 3.x is:
-
-                         % stunnel -c -d localhost:5901 -r remotehost:5900
-                         % vncviewer localhost:1
-
-                       For Windows, stunnel has been ported to it and there
-                       are probably other such tools available.  See the FAQ
-                       and SSVNC for more examples.
-
--stunnel3  [pem]       Use version 3.x stunnel command line syntax instead of
-                       version 4.x.  The -http/-httpdir Java applet serving
-                       is currently not available in this mode.
-
--enc cipher:keyfile    Use symmetric encryption with cipher "cipher"
-                       and secret key data in "keyfile".  If keyfile is
-                       pw=<string> then "string" is used as the key data.
-
-                       NOTE: It is recommended that you use SSL via the -ssl
-                       option instead of this option because SSL is well
-                       understood and takes great care to establish unique
-                       session keys and is more compatible with other software.
-                       Use this option if you do not want to deal with SSL
-                       certificates for authentication and do not want to
-                       use SSH but want some encryption for your VNC session.
-                       Or if you must interface with a symmetric key tunnel
-                       that you do not have control over.
-
-                       Note that this mode will NOT work with the UltraVNC DSM
-                       plugins because they alter the RFB protocol in addition
-                       to tunnelling with the symmetric cipher (an unfortunate
-                       choice of implementation...)
-
-                       cipher can be one of:  arc4, aesv2, aes-cfb, blowfish,
-                       aes256, or 3des.  See the OpenSSL documentation for
-                       more info.  The keysize is 128 bits (except for aes256).
-                       Here is one way to make a keyfile with that many bits:
-
-                            dd if=/dev/random of=./my.key bs=16 count=1
-
-                       you will need to securely share this key with the other
-                       side of the VNC connection (See SSVNC for examples).
-
-                       Example:  -enc blowfish:./my.key
-                       Example:  -enc blowfish:pw=swordfish
-
-                       By default 16 bytes of random salt followed by 16 bytes
-                       of random initialization vector are sent at the very
-                       beginning of the stream.  The other side must read these
-                       and initialize their cipher with them.  These values
-                       make the session key unique (without them the security
-                       is minimal).  Similarly, the other side must send us
-                       its random salt and IV with those same lengths.
-
-                       The salt and key data are combined to create a session
-                       key using an md5 hash as described in EVP_BytesToKey(3).
-
-                       The exact call is: EVP_BytesToKey(Cipher, EVP_md5(),
-                       salt, keydata, len, 1, keystr, NULL);  where salt is
-                       the random data as described above, and keydata is the
-                       shared secret key data.  keystr is the resulting session
-                       key.  The cipher is then seeded with keystr and uses
-                       the random initialization vector as its first block.
-
-                       To modify the amount of random salt and initialization
-                       vector use cipher@n,m where n is the salt length and
-                       m the initialization vector length.  E.g.
-
-                                 -enc aes-cfb@8,16:./my.key
-
-                       It is not a good idea to set either one to zero,
-                       although you may be forced to if the other side of the
-                       tunnel is not under your control.
-
-                       To skip the salt and EVP_BytesToKey MD5 entirely (no
-                       hashing is done: the keydata is directly inserted into
-                       the cipher) specify "-1" for the salt, e.g.
-
-                                 -enc blowfish@-1,16:./my.key
-
-                       The message digest can also be changed to something
-                       besides the default MD5.  Use cipher@md+n,m where "md"
-                       can be one of sha, sha1, md5, or ripe.  For example:
-
-                                 -enc arc4@sha+8,16:./my.key
-
-                       The SSVNC vnc viewer project supplies a symmetric
-                       encryption tool named "ultravnc_dsm_helper" that can
-                       be used on the viewer side.  For example:
-
-                       ssvncviewer exec='ultravnc_dsm_helper arc4 my.key 0 h:p'
-
-                       where h:p is the hostname and port of the x11vnc server.
-                       ultravnc_dsm_helper may also be used standalone to
-                       provide a symmetric encryption tunnel for any viewer
-                       or server (VNC or otherwise.) The cipher (1st arg)
-                       is basically the same syntax as we use above.
-
-                       Also see the 'Non-Ultra DSM' SSVNC option for the
-                       'UltraVNC DSM Encryption Plugin' advanced option.
-
-                       For both ways of using the viewer, you can specify the
-                       salt,ivec sizes (in GUI or, e.g. arc4@8,16).
-
--https [port]          Use a special, separate HTTPS port (-ssl and
-                       -stunnel modes only) for HTTPS Java viewer applet
-                       downloading. I.e. not 5900 and not 5800 (the defaults.)
-
-                       BACKGROUND: In -ssl mode, it turns out you can use the
-                       single VNC port (e.g. 5900) for both VNC and HTTPS
-                       connections. (HTTPS is used to retrieve a SSL-aware
-                       VncViewer.jar applet that is provided with x11vnc).
-                       Since both use SSL the implementation was extended to
-                       detect if HTTP traffic (i.e. GET) is taking place and
-                       handle it accordingly.  The URL would be, e.g.:
-
-                       https://mymachine.org:5900/
-
-                       This is convenient for firewalls, etc, because only one
-                       port needs to be allowed in.  However, this heuristic
-                       adds a few seconds delay to each connection and can be
-                       unreliable (especially if the user takes much time to
-                       ponder the Certificate dialogs in his browser, Java VM,
-                       or VNC Viewer applet.  That's right 3 separate "Are
-                       you sure you want to connect?" dialogs!)
-
-                       END OF BACKGROUND.
-
-                       USAGE: So use the -https option to provide a separate,
-                       more reliable HTTPS port that x11vnc will listen on.  If
-                       [port] is not provided (or is 0), one is autoselected.
-                       The URL to use is printed out at startup.
-
-                       The SSL Java applet directory is specified via the
-                       -httpdir option.  If not supplied, -https will try
-                       to guess the directory as though the -http option
-                       was supplied.
-
--httpsredir [port]     In -ssl mode with the Java applet retrieved via HTTPS,
-                       when the HTML file containing applet parameters
-                       ('index.vnc' or 'proxy.vnc') is sent do NOT set the
-                       applet PORT parameter to the actual VNC port but set it
-                       to "port" instead.  If "port" is not supplied, then
-                       the port number is guessed from the Host: HTTP header.
-
-                       This is useful when an incoming TCP connection
-                       redirection is performed by a router/gateway/firewall
-                       from one port to an internal machine where x11vnc is
-                       listening on a different port. The Java applet needs to
-                       connect to the firewall/router port, not the VNC port
-                       on the internal workstation. For example, one could
-                       redir from mygateway.com:443 to workstation:5900.
-
-                       This spares the user from having to type in
-                       https://mygateway.com/?PORT=443 into their web
-                       browser. Note that port 443 is the default https port;
-                       other ports must be explicitly indicated, for example:
-                       https://mygateway.com:8000/?PORT=8000.  To avoid having
-                       to include the PORT= in the browser URL, simply supply
-                       "-httpsredir" to x11vnc.
-
-                       This option does not work in -stunnel mode.
-
-                       More tricks: set the env var X11VNC_EXTRA_HTTPS_PARAMS
-                       to be extra URL parameters to use.  This way you do
-                       not need to specify extra PARAMS in the index.vnc file.
-                       E.g. x11vnc -env X11VNC_EXTRA_HTTPS_PARAMS='?GET=1' ...
-
-                       If you do not want to expose the non-SSL HTTP port to
-                       the network (i.e. you just want the single VNC/HTTPS
-                       port, e.g. 5900, open for connections) then specify the
-                       option -env X11VNC_HTTP_LISTEN_LOCALHOST=1  This way
-                       the connection to the LibVNCServer httpd server will
-                       only be available on localhost (note that in -ssl mode,
-                       HTTPS requests are redirected from SSL to the non-SSL
-                       LibVNCServer HTTP server.)
-
--http_oneport          For UN-encrypted connections mode (i.e. no -ssl,
-                       -stunnel, or -enc options), allow the Java VNC Viewer
-                       applet to be downloaded thru the VNC port via HTTP.
-
-                       That is to say, you can use a single port for Java
-                       applet viewer connections by using a URL in your web
-                       browser like this, for example:
-
-                       http://hostname:5900
-
-                       The regular, two-port mode, URL http://hostname:5800
-                       will continue to work as well.
-
-                       As mentioned above, this mode will NOT work with
-                       the -ssl, -stunnel, or -enc encryption options.
-                       Note that is it equivalent to '-enc none' (i.e. it
-                       uses the same detection mechanism as for HTTPS, but
-                       with no encryption.)
-
-                       HTTPS single-port is on by default in -ssl encrypted
-                       mode (and -enc too), so you only need -http_oneport
-                       when doing non-SSL encrypted connections.
-
-                       This mode could also be useful for SSH tunnels since
-                       it means only one port needs to be redirected.
-
-                       The -httpsredir option may also be useful for this
-                       mode when using an SSH tunnel as well as for router
-                       port redirections.
-
-                       Note that the -env X11VNC_HTTP_LISTEN_LOCALHOST=1
-                       option described above under -httpsredir applies for
-                       the LibVNCServer httpd server in all cases (ssl or not.)
-
--ssh user@host:disp    Create a remote listening port on machine "host"
-                       via a SSH tunnel using the -R rport:localhost:lport
-                       method. lport will be the local x11vnc listening port,
-                       so a connection to rport (5900+disp) on "host"
-                       will reach x11vnc.  E.g. fred@snoopy.com:0
-
-                       This could be useful if a firewall/router prevents
-                       incoming connections to the x11vnc machine, but
-                       the ssh machine "host" can be reached by the VNC
-                       viewer. "user@" is not needed unless the remote unix
-                       username differs from the current one.
-
-                       By default the remote sshd is usually configured to
-                       listen only on localhost for rport, so the viewer may
-                       need to ssh -L redir to "host" as well (See SSVNC to
-                       automate this).  The sshd setting GatewayPorts enables
-                       listening on all interfaces for rport; viewers can
-                       reach it more easily.
-
-                       "disp" is the VNC display for the remote SSH side,
-                       e.g. 0 corresponds to port 5900, etc.  If disp is
-                       greater than 200 the value is used as the port.  Use a
-                       negative value to force a low port, e.g. host:-80 will
-                       use port 80.
-
-                       If ssh-agent is not active, then the ssh password needs
-                       to be entered in the terminal where x11vnc is running.
-
-                       By default the remote ssh will issue a 'sleep 300' to
-                       wait for the incoming connection for 5 mins.  To modify
-                       this use user@host:disp+secs.
-
-                       If the remote SSH server is on a non-standard port
-                       (i.e. not 22) use user@host:port:disp+secs.
-
-                       Note that the ssh process MAY NOT be killed when
-                       x11vnc exits.  It tries by looking at ps(1) output.
-
--usepw                 If no other password method was supplied on the command
-                       line, first look for ~/.vnc/passwd and if found use it
-                       with -rfbauth; next, look for ~/.vnc/passwdfile and
-                       use it with -passwdfile; otherwise, prompt the user
-                       for a password to create ~/.vnc/passwd and use it with
-                       the -rfbauth option.  If none of these succeed x11vnc
-                       exits immediately.
-
--storepasswd pass file Store password "pass" as the VNC password in the
-                       file "file".  Once the password is stored the
-                       program exits.  Use the password via "-rfbauth file"
-
-                       If called with no arguments, "x11vnc -storepasswd",
-                       the user is prompted for a password and it is stored
-                       in the file ~/.vnc/passwd.  Called with one argument,
-                       that will be the file to store the prompted password in.
-
--nopw                  Disable the big warning message when you use x11vnc
-                       without some sort of password.
-
--accept string         Run a command (possibly to prompt the user at the
-                       X11 display) to decide whether an incoming client
-                       should be allowed to connect or not.  "string" is
-                       an external command run via system(3) or some special
-                       cases described below.  Be sure to quote "string"
-                       if it contains spaces, shell characters, etc.  If the
-                       external command returns 0 the client is accepted,
-                       otherwise the client is rejected.  See below for an
-                       extension to accept a client view-only.
-
-                       If x11vnc is running as root (say from inetd(8) or from
-                       display managers xdm(1), gdm(1), etc), think about the
-                       security implications carefully before supplying this
-                       option (likewise for the -gone option).
-
-                       Environment: The RFB_CLIENT_IP environment variable will
-                       be set to the incoming client IP number and the port
-                       in RFB_CLIENT_PORT (or -1 if unavailable).  Similarly,
-                       RFB_SERVER_IP and RFB_SERVER_PORT (the x11vnc side
-                       of the connection), are set to allow identification
-                       of the tcp virtual circuit.  The x11vnc process
-                       id will be in RFB_X11VNC_PID, a client id number in
-                       RFB_CLIENT_ID, and the number of other connected clients
-                       in RFB_CLIENT_COUNT.  RFB_MODE will be "accept".
-                       RFB_STATE will be PROTOCOL_VERSION, SECURITY_TYPE,
-                       AUTHENTICATION, INITIALISATION, NORMAL, or UNKNOWN
-                       indicating up to which state the client has achieved.
-                       RFB_LOGIN_VIEWONLY will be 0, 1, or -1 (unknown).
-                       RFB_USERNAME, RFB_LOGIN_TIME, and RFB_CURRENT_TIME may
-                       also be set.
-
-                       If "string" is "popup" then a builtin popup window
-                       is used.  The popup will time out after 120 seconds,
-                       use "popup:N" to modify the timeout to N seconds
-                       (use 0 for no timeout).
-
-                       In the case of "popup" and when the -unixpw option
-                       is specified, then a *second* window will be popped
-                       up after the user successfully logs in via his UNIX
-                       password.  This time the user will be identified as
-                       UNIX:username@hostname, the "UNIX:" prefix indicates
-                       which user the viewer logged as via -unixpw.  The first
-                       popup is only for whether to allow him to even *try*
-                       to login via unix password.
-
-                       If "string" is "xmessage" then an xmessage(1)
-                       invocation is used for the command.  xmessage must be
-                       installed on the machine for this to work.
-
-                       Both "popup" and "xmessage" will present an option
-                       for accepting the client "View-Only" (the client
-                       can only watch).  This option will not be presented if
-                       -viewonly has been specified, in which case the entire
-                       display is view only.
-
-                       If the user supplied command is prefixed with something
-                       like "yes:0,no:*,view:3 mycommand ..." then this
-                       associates the numerical command return code with
-                       the actions: accept, reject, and accept-view-only,
-                       respectively.  Use "*" instead of a number to indicate
-                       the default action (in case the command returns an
-                       unexpected value).  E.g. "no:*" is a good choice.
-
-                       Note that x11vnc blocks while the external command
-                       or popup is running (other clients may see no updates
-                       during this period).  So a person sitting a the physical
-                       display is needed to respond to an popup prompt. (use
-                       a 2nd x11vnc if you lock yourself out).
-
-                       More -accept tricks: use "popupmouse" to only allow
-                       mouse clicks in the builtin popup to be recognized.
-                       Similarly use "popupkey" to only recognize
-                       keystroke responses.  These are to help avoid the
-                       user accidentally accepting a client by typing or
-                       clicking. All 3 of the popup keywords can be followed
-                       by +N+M to supply a position for the popup window.
-                       The default is to center the popup window.
--afteraccept string    As -accept, except to run a user supplied command after
-                       a client has been accepted and authenticated. RFB_MODE
-                       will be set to "afteraccept" and the other RFB_*
-                       variables are as in -accept.  Unlike -accept, the
-                       command return code is not interpreted by x11vnc.
-                       Example: -afteraccept 'killall xlock &'
--gone string           As -accept, except to run a user supplied command when
-                       a client goes away (disconnects).  RFB_MODE will be
-                       set to "gone" and the other RFB_* variables are as
-                       in -accept.  The "popup" actions apply as well.
-                       Unlike -accept, the command return code is not
-                       interpreted by x11vnc.  Example: -gone 'xlock &'
-
--users list            If x11vnc is started as root (say from inetd(8) or from
-                       display managers xdm(1), gdm(1), etc), then as soon
-                       as possible after connections to the X display are
-                       established try to switch to one of the users in the
-                       comma separated "list".  If x11vnc is not running as
-                       root this option is ignored.
-
-                       Why use this option?  In general it is not needed since
-                       x11vnc is already connected to the X display and can
-                       perform its primary functions.  The option was added
-                       to make some of the *external* utility commands x11vnc
-                       occasionally runs work properly.  In particular under
-                       GNOME and KDE to implement the "-solid color" feature
-                       external commands (gconftool-2 and dcop) unfortunately
-                       must be run as the user owning the desktop session.
-                       Since this option switches userid it also affects the
-                       userid used to run the processes for the -accept and
-                       -gone options.  It also affects the ability to read
-                       files for options such as -connect, -allow, and -remap
-                       and also the ultra and tight filetransfer feature if
-                       enabled.  Note that the -connect file is also sometimes
-                       written to.
-
-                       So be careful with this option since in some situations
-                       its use can decrease security.
-
-                       In general the switch to a user will only take place
-                       if the display can still be successfully opened as that
-                       user (this is primarily to try to guess the actual owner
-                       of the session). Example: "-users fred,wilma,betty".
-                       Note that a malicious local user "barney" by
-                       quickly using "xhost +" when logging in may possibly
-                       get the x11vnc process to switch to user "fred".
-                       What happens next?
-
-                       Under display managers it may be a long time before
-                       the switch succeeds (i.e. a user logs in).  To instead
-                       make it switch immediately regardless if the display
-                       can be reopened prefix the username with the "+"
-                       character. E.g. "-users +bob" or "-users +nobody".
-
-                       The latter (i.e. switching immediately to user
-                       "nobody") is the only obvious use of the -users option
-                       that increases security.
-
-                       Use the following notation to associate a group with
-                       a user: user1.group1,user2.group2,...  Note that
-                       initgroups(2) will still be called first to try to
-                       switch to ALL of a user's groups (primary and additional
-                       groups).  Only if that fails or it is not available
-                       then the single group specified as above (or the user's
-                       primary group if not specified) is switched to with
-                       setgid(2).  Use -env X11VNC_SINGLE_GROUP=1 to prevent
-                       trying initgroups(2) and only switch to the single
-                       group.  This sort of setting is only really needed to
-                       make the ultra or tight filetransfer permissions work
-                       properly. This format applies to any comma separated lis
-t
-                       of users, even the special "=" modes described below.
-
-                       In -unixpw mode, if "-users unixpw=" is supplied
-                       then after a user authenticates himself via the
-                       -unixpw mechanism, x11vnc will try to switch to that
-                       user as though "-users +username" had been supplied.
-                       If you want to limit which users this will be done for,
-                       provide them as a comma separated list after "unixpw="
-                       Groups can also be specified as described above.
-
-                       Similarly, in -ssl mode, if "-users sslpeer=" is
-                       supplied then after an SSL client authenticates with his
-                       cert (the -sslverify option is required for this) x11vnc
-                       will extract a UNIX username from the "emailAddress"
-                       field (username@hostname.com) of the "Subject" of the
-                       x509 SSL cert and then try to switch to that user as
-                       though "-users +username" had been supplied.  If you
-                       want to limit which users this will be done for, provide
-                       them as a comma separated list after "sslpeer=".
-                       Set the env. var X11VNC_SSLPEER_CN to use the Common
-                       Name (normally a hostname) instead of the Email field.
-
-                       NOTE: for sslpeer= mode the x11vnc administrator must
-                       take care that any client certs he adds to -sslverify
-                       have the intended UNIX username in the "emailAddress"
-                       field of the cert.  Otherwise a user may be able to
-                       log in as another.  This command can be of use in
-                       checking: "openssl x509 -text -in file.crt", see the
-                       "Subject:" line.  Also, along with the normal RFB_*
-                       env. vars. (see -accept) passed to external cmd=
-                       commands, RFB_SSL_CLIENT_CERT will be set to the
-                       client's x509 certificate string.
-
-                       The sslpeer= mode can aid finding X sessions via the
-                       FINDDISPLAY and FINDCREATEDISPLAY mechanisms.
-
-                       To immediately switch to a user *before* connections
-                       to the X display are made or any files opened use the
-                       "=" character: "-users =bob".  That user needs to
-                       be able to open the X display and any files of course.
-
-                       The special user "guess=" means to examine the utmpx
-                       database (see who(1)) looking for a user attached to
-                       the display number (from DISPLAY or -display option)
-                       and try him/her.  To limit the list of guesses, use:
-                       "-users guess=bob,betty".
-
-                       Even more sinister is the special user "lurk="
-                       that means to try to guess the DISPLAY from the utmpx
-                       login database as well.  So it "lurks" waiting for
-                       anyone to log into an X session and then connects to it.
-                       Specify a list of users after the = to limit which users
-                       will be tried.  To enable a different searching mode, if
-                       the first user in the list is something like ":0" or
-                       ":0-2" that indicates a range of DISPLAY numbers that
-                       will be tried (regardless of whether they are in the
-                       utmpx database) for all users that are logged in.  Also
-                       see the "-display WAIT:..." functionality.  Examples:
-                       "-users lurk=" and also "-users lurk=:0-1,bob,mary"
-
-                       Be especially careful using the "guess=" and "lurk="
-                       modes.  They are not recommended for use on machines
-                       with untrustworthy local users.
-
--noshm                 Do not use the MIT-SHM extension for the polling.
-                       Remote displays can be polled this way: be careful this
-                       can use large amounts of network bandwidth.  This is
-                       also of use if the local machine has a limited number
-                       of shm segments and -onetile is not sufficient.
--flipbyteorder         Sometimes needed if remotely polled host has different
-                       endianness.  Ignored unless -noshm is set.
--onetile               Do not use the new copy_tiles() framebuffer mechanism,
-                       just use 1 shm tile for polling.  Limits shm segments
-                       used to 3.
-
-                       To disable any automatic shm reduction set the
-                       env. var. X11VNC_NO_LIMIT_SHM.
-
--solid [color]         To improve performance, when VNC clients are connected
-                       try to change the desktop background to a solid color.
-                       The [color] is optional: the default color is "cyan4".
-                       For a different one specify the X color (rgb.txt name,
-                       e.g. "darkblue" or numerical "#RRGGBB").
-
-                       Currently this option only works on GNOME, KDE, CDE,
-                       XFCE, and classic X (i.e. with the background image
-                       on the root window).  The "gconftool-2", "dcop"
-                       and "xfconf-query" external commands are run for
-                       GNOME, KDE, and XFCE respectively.  This also works
-                       on native MacOSX.  (There is no color selection for
-                       MacOSX or XFCE.)  Other desktops won't work, (send
-                       us the corresponding commands if you find them).
-                       If x11vnc is running as root (inetd(8) or gdm(1)),
-                       the -users option may be needed for GNOME, KDE, XFCE.
-                       If x11vnc guesses your desktop incorrectly, you can
-                       force it by prefixing color with "gnome:", "kde:",
-                       "cde:", "xfce:", or "root:".
-
-                       Update: -solid no longer works on KDE4.
-
-                       This mode works in a limited way on the Mac OS X Console
-                       with one color ('kelp') using the screensaver writing
-                       to the background.  Look in "~/Library/Screen Savers"
-                       for VncSolidColor.png to change the color.
-
--blackout string       Black out rectangles on the screen. "string" is a
-                       comma separated list of WxH+X+Y type geometries for
-                       each rectangle.  If one of the items on the list is the
-                       string "noptr" the mouse pointer will not be allowed
-                       to go into a blacked out region.
--xinerama              If your screen is composed of multiple monitors
--noxinerama            glued together via XINERAMA, and that screen is
-                       not a rectangle this option will try to guess the
-                       areas to black out (if your system has libXinerama).
-                       default: -xinerama
-
-                       In general, we have noticed on XINERAMA displays you may
-                       need to use the "-xwarppointer" option if the mouse
-                       pointer misbehaves and it is enabled by default. Use
-                       "-noxwarppointer" if you do not want this.
-
--xtrap                 Use the DEC-XTRAP extension for keystroke and mouse
-                       input insertion.  For use on legacy systems, e.g. X11R5,
-                       running an incomplete or missing XTEST extension.
-                       By default DEC-XTRAP will be used if XTEST server grab
-                       control is missing, use -xtrap to do the keystroke and
-                       mouse insertion via DEC-XTRAP as well.
-
--xrandr [mode]         If the display supports the XRANDR (X Resize, Rotate
-                       and Reflection) extension, and you expect XRANDR events
-                       to occur to the display while x11vnc is running, this
-                       options indicates x11vnc should try to respond to
-                       them (as opposed to simply crashing by assuming the
-                       old screen size).  See the xrandr(1) manpage and run
-                       'xrandr -q' for more info.  [mode] is optional and
-                       described below.
-
-                       Since watching for XRANDR events and trapping errors
-                       increases polling overhead, only use this option if
-                       XRANDR changes are expected.  For example on a rotatable
-                       screen PDA or laptop, or using a XRANDR-aware Desktop
-                       where you resize often.  It is best to be viewing with a
-                       vncviewer that supports the NewFBSize encoding, since it
-                       knows how to react to screen size changes.  Otherwise,
-                       LibVNCServer tries to do so something reasonable for
-                       viewers that cannot do this (portions of the screen
-                       may be clipped, unused, etc).
-
-                       Note: the default now is to check for XRANDR events, but
-                       do not trap every X call that may fail due to resize.
-                       If a resize event is received, the full -xrandr mode
-                       is enabled.  To disable even checking for events supply:
-                       -noxrandr.
-
-                       "mode" defaults to "resize", which means create a
-                       new, resized, framebuffer and hope all viewers can cope
-                       with the change.  "newfbsize" means first disconnect
-                       all viewers that do not support the NewFBSize VNC
-                       encoding, and then resize the framebuffer.  "exit"
-                       means disconnect all viewer clients, and then terminate
-                       x11vnc.
-
--rotate string         Rotate and/or flip the framebuffer view exported by VNC.
-                       This transformation is independent of XRANDR and is
-                       done in software in main memory and so may be slower.
-                       This mode could be useful on a handheld with portrait or
-                       landscape modes that do not correspond to the scanline
-                       order of the actual framebuffer.  "string" can be:
-
-                             x     flip along x-axis
-                             y     flip along y-axis
-                            xy     flip along x- and y-axes
-                           +90     rotate 90 degrees clockwise
-                           -90     rotate 90 degrees counter-clockwise
-                          +90x     rotate 90 degrees CW, then flip along x
-                          +90y     rotate 90 degrees CW, then flip along y
-
-                       these give all possible rotations and reflections.
-
-                       Aliases: same as xy:  yx, +180, -180, 180
-                                same as -90: +270, 270
-                                same as +90: 90, (ditto for 90x, 90y)
-
-                       Like -scale, this transformation is applied at the very
-                       end of any chain of framebuffer transformations and so
-                       any options with geometries, e.g. -blackout, -clip, etc.
-                       are relative to the original X (or -rawfb) framebuffer,
-                       not the final one sent to VNC viewers.
-
-                       If you do not want the cursor shape to be rotated
-                       prefix "string" with "nc:", e.g. "nc:+90",
-                       "nc:xy", etc.
-
--padgeom WxH           Whenever a new vncviewer connects, the framebuffer is
-                       replaced with a fake, solid black one of geometry WxH.
-                       Shortly afterwards the framebuffer is replaced with the
-                       real one.  This is intended for use with vncviewers
-                       that do not support NewFBSize and one wants to make
-                       sure the initial viewer geometry will be big enough
-                       to handle all subsequent resizes (e.g. under -xrandr,
-                       -remote id:windowid, rescaling, etc.)
-
-                       In -unixpw mode this sets the size of the login screen.
-                       Use "once:WxH" it ignore padgeom after the login
-                       screen is set up.
-
--o logfile             Write stderr messages to file "logfile" instead of to
-                       the terminal.  Same as "-logfile file".  To append
-                       to the file use "-oa file" or "-logappend file".
-                       If "logfile" contains the string "%VNCDISPLAY"
-                       it is expanded to the vnc display (the name may need
-                       to be guessed at.)  "%HOME" works too.
-
--flag file             Write the "PORT=NNNN" (e.g. PORT=5900) string to
-                       "file" in addition to stdout.  This option could be
-                       useful by wrapper script to detect when x11vnc is ready.
-
--rmflag file           Remove "file" at exit to signal when x11vnc is done.
-                       The file is created at startup if it does not already
-                       exist or if "file" is prefixed with "create:".
-                       If the file is created, the x11vnc PID is placed in
-                       the file.  Otherwise the files contents is not changed.
-                       Use prefix "nocreate:" to prevent creation.
-
--rc filename           Use "filename" instead of $HOME/.x11vncrc for rc file.
--norc                  Do not process any .x11vncrc file for options.
-
--env VAR=VALUE         Set the environment variable 'VAR' to value 'VALUE'
-                       at x11vnc startup.  This is a convenience utility to
-                       avoid shell script wrappers, etc. to set the env. var.
-                       You may specify as many of these as needed on the
-                       command line.
--prog /path/to/x11vnc  Set the full path to the x11vnc program for cases when
-                       it cannot be determined from argv[0] (e.g. tcpd/inetd)
-
--h, -help              Print this help text.
--?, -opts              Only list the x11vnc options.
--V, -version           Print program version and last modification date.
--license               Print out license information.  Same as -copying and
-                       -warranty.
-
--dbg                   Instead of exiting after cleaning up, run a simple
-                       "debug crash shell" when fatal errors are trapped.
-
--q, -quiet             Be quiet by printing less informational output to
-                       stderr. (use -noquiet to undo an earlier -quiet.)
-
-                       The -quiet option does not eliminate all informational
-                       output, it only reduces it.  It is ignored in most
-                       auxiliary usage modes, e.g. -storepasswd.  To eliminate
-                       all output use: 2>/dev/null 1>&2, etc.
-
--v, -verbose           Print out more information to stderr.
-
--bg                    Go into the background after screen setup.  Messages to
-                       stderr are lost unless -o logfile is used.  Something
-                       like this could be useful in a script:
-                        port=`ssh -t $host "x11vnc -display :0 -bg" | grep PORT
-`
-                        port=`echo "$port" | sed -e 's/PORT=//'`
-                        port=`expr $port - 5900`
-                        vncviewer $host:$port
-
--modtweak              Option -modtweak automatically tries to adjust the AltGr
--nomodtweak            and Shift modifiers for differing language keyboards
-                       between client and host.  Otherwise, only a single key
-                       press/release of a Keycode is simulated (i.e. ignoring
-                       the state of the modifiers: this usually works for
-                       identical keyboards).  Also useful in resolving cases
-                       where a Keysym is bound to multiple keys (e.g. "<" + ">"
-                       and "," + "<" keys).  Default: -modtweak
-
-                       If you are having trouble with with keys and -xkb or
-                       -noxkb, and similar things don't help, try -nomodtweak.
-
-                       On some HP-UX systems it is been noted that they have
-                       an odd keymapping where a single keycode will have a
-                       keysym, e.g. "#", up to three times.  You can check
-                       via "xmodmap -pk" or the -dk option.  The failure
-                       is when you try to type "#" it yields "3".  If you
-                       see this problem try setting the environment variable
-                       MODTWEAK_LOWEST=1 to see if it helps.
-
--xkb                   When in modtweak mode, use the XKEYBOARD extension (if
--noxkb                 the X display supports it) to do the modifier tweaking.
-                       This is powerful and should be tried if there are still
-                       keymapping problems when using -modtweak by itself.
-                       The default is to check whether some common keysyms,
-                       e.g. !, @, [, are only accessible via -xkb mode and if
-                       so then automatically enable the mode.  To disable this
-                       automatic detection use -noxkb.
-
-                       When -xkb mode is active you can set these env. vars.
-                       They apply only when there is ambiguity as to which
-                       key to choose (i.e the mapping is not one-to-one).
-                       NOKEYHINTS=1: for up ascii keystrokes do not use score
-                       hints saved when the key was pressed down. NOANYDOWN=1:
-                       for up keystrokes do not resort to searching through
-                       keys that are currently pressed down.  KEYSDOWN=N:
-                       remember the last N keys press down for tie-breaking
-                       when an up keystroke comes in.
-
--capslock              When in -modtweak (the default) or -xkb mode,
-                       if a keysym in the range A-Z comes in check the X
-                       server to see if the Caps_Lock is set.  If it is do
-                       not artificially press Shift to generate the keysym.
-                       This will enable the CapsLock key to behave correctly
-                       in some circumstances: namely *both* the VNC viewer
-                       machine and the x11vnc X server are in the CapsLock
-                       on state.  If one side has CapsLock on and the other
-                       off and the keyboard is not behaving as you think it
-                       should you should correct the CapsLock states (hint:
-                       pressing CapsLock inside and outside of the viewer can
-                       help toggle them both to the correct state).  However,
-                       for best results do not use this option, but rather
-                       *only* enable CapsLock on the VNC viewer side (i.e. by
-                       pressing CapsLock outside of the viewer window, also
-                       -skip_lockkeys below).  Also try -nomodtweak for a
-                       possible workaround.
-
--skip_lockkeys         Have x11vnc ignore all Caps_Lock, Shift_Lock, Num_Lock,
--noskip_lockkeys       Scroll_Lock keysyms received from viewers.  The idea is
-                       you press Caps_Lock on the VNC Viewer side but that does
-                       not change the lock state in the x11vnc-side X server.
-                       Nevertheless your capitalized letters come in over
-                       the wire and are applied correctly to the x11vnc-side
-                       X server.  Note this mode probably won't do what you
-                       want in -nomodtweak mode.  Also, a kludge for KP_n
-                       digits is always done in this mode: they are mapped to
-                       regular digit keysyms.  See also -capslock above.
-                       The default is -noskip_lockkeys.
-
--skip_keycodes string  Ignore the comma separated list of decimal keycodes.
-                       Perhaps these are keycodes not on your keyboard but
-                       your X server thinks exist.  Currently only applies
-                       to -xkb mode.  Use this option to help x11vnc in the
-                       reverse problem it tries to solve: Keysym -> Keycode(s)
-                       when ambiguities exist (more than one Keycode per
-                       Keysym).  Run 'xmodmap -pk' to see your keymapping.
-                       Example: "-skip_keycodes 94,114"
--sloppy_keys           Experimental option that tries to correct some
-                       "sloppy" key behavior.  E.g. if at the viewer you
-                       press Shift+Key but then release the Shift before
-                       Key that could give rise to extra unwanted characters
-                       (usually only between keyboards of different languages).
-                       Only use this option if you observe problems with
-                       some keystrokes.
--skip_dups             Some VNC viewers send impossible repeated key events,
--noskip_dups           e.g. key-down, key-down, key-up, key-up all for the same
-                       key, or 20 downs in a row for the same modifier key!
-                       Setting -skip_dups means to skip these duplicates and
-                       just process the first event. Note: some VNC viewers
-                       assume they can send down's without the corresponding
-                       up's and so you should not set this option for
-                       these viewers (symptom: some keys do not autorepeat)
-                       Default: -noskip_dups
--add_keysyms           If a Keysym is received from a VNC viewer and that
--noadd_keysyms         Keysym does not exist in the X server, then add the
-                       Keysym to the X server's keyboard mapping on an unused
-                       key.  Added Keysyms will be removed periodically and
-                       also when x11vnc exits.  Default: -add_keysyms
--clear_mods            At startup and exit clear the modifier keys by sending
-                       KeyRelease for each one. The Lock modifiers are skipped.
-                       Used to clear the state if the display was accidentally
-                       left with any pressed down.
--clear_keys            As -clear_mods, except try to release ANY pressed key.
-                       Note that this option and -clear_mods can interfere
-                       with a person typing at the physical keyboard.
--clear_all             As -clear_keys, except try to release any CapsLock,
-                       NumLock, etc. locks as well.
-
--remap string          Read Keysym remappings from file named "string".
-                       Format is one pair of Keysyms per line (can be name
-                       or hex value) separated by a space.  If no file named
-                       "string" exists, it is instead interpreted as this
-                       form: key1-key2,key3-key4,...  See <X11/keysymdef.h>
-                       header file for a list of Keysym names, or use xev(1).
-
-                       To map a key to a button click, use the fake Keysyms
-                       "Button1", ..., etc. E.g: "-remap Super_R-Button2"
-                       (useful for pasting on a laptop)
-
-                       I use these if the machine I am viewing from does not
-                       have a scrollwheel or I don't like using the one it has:
-
-                              -remap Super_R-Button4,Menu-Button5
-                              -remap KP_Add-Button4,KP_Enter-Button5
-
-                       the former would be used on a PC, the latter on a
-                       MacBook.  This way those little used keys can be used
-                       to generate bigger hops than the Up and Down arrows
-                       provide.  One can scroll through text or web pages more
-                       quickly this way (especially if x11vnc scroll detection
-                       is active.)
-
-                       Use Button44, Button12, etc. for multiple clicks.
-
-                       To disable a keysym (i.e. make it so it will not be
-                       injected), remap it to "NoSymbol" or "None".
-
-                       Dead keys: "dead" (or silent, mute) keys are keys that
-                       do not produce a character but must be followed by a 2nd
-                       keystroke.  This is often used for accenting characters,
-                       e.g. to put "`" on top of "a" by pressing the dead
-                       key and then "a".  Note that this interpretation
-                       is not part of core X11, it is up to the toolkit or
-                       application to decide how to react to the sequence.
-                       The X11 names for these keysyms are "dead_grave",
-                       "dead_acute", etc.  However some VNC viewers send the
-                       keysyms "grave", "acute" instead thereby disabling
-                       the accenting.  To work around this -remap can be used.
-                       For example "-remap grave-dead_grave,acute-dead_acute"
-                       As a convenience, "-remap DEAD" applies these remaps:
-
-                               g     grave-dead_grave
-                               a     acute-dead_acute
-                               c     asciicircum-dead_circumflex
-                               t     asciitilde-dead_tilde
-                               m     macron-dead_macron
-                               b     breve-dead_breve
-                               D     abovedot-dead_abovedot
-                               d     diaeresis-dead_diaeresis
-                               o     degree-dead_abovering
-                               A     doubleacute-dead_doubleacute
-                               r     caron-dead_caron
-                               e     cedilla-dead_cedilla
-
-                       If you just want a subset use the first letter
-                       label, e.g. "-remap DEAD=ga" to get the first two.
-                       Additional remaps may also be supplied via commas,
-                       e.g.  "-remap DEAD=ga,Super_R-Button2".  Finally,
-                       "DEAD=missing" means to apply all of the above as
-                       long as the left hand member is not already in the
-                       X11 keymap.
-
--norepeat              Option -norepeat disables X server key auto repeat when
--repeat                VNC clients are connected and VNC keyboard input is
-                       not idle for more than 5 minutes.  This works around a
-                       repeating keystrokes bug (triggered by long processing
-                       delays between key down and key up client events:
-                       either from large screen changes or high latency).
-                       Default: -norepeat
-
-                       You can set the env. var. X11VNC_IDLE_TIMEOUT to the
-                       number of idle seconds you want (5min = 300secs).
-
-                       Note: your VNC viewer side will likely do autorepeating,
-                       so this is no loss unless someone is simultaneously at
-                       the real X display.
-
-                       Use "-norepeat N" to set how many times norepeat will
-                       be reset if something else (e.g. X session manager)
-                       undoes it.  The default is 2.  Use a negative value
-                       for unlimited resets.
-
--nofb                  Ignore video framebuffer: only process keyboard and
-                       pointer.  Intended for use with Win2VNC and x2vnc
-                       dual-monitor setups.
--nobell                Do not watch for XBell events. (no beeps will be heard)
-                       Note: XBell monitoring requires the XKEYBOARD extension.
--nosel                 Do not manage exchange of X selection/cutbuffer between
-                       VNC viewers and the X server at all.
--noprimary             Do not poll the PRIMARY selection for changes to send
-                       back to clients.  (PRIMARY is still set on received
-                       changes, however).
--nosetprimary          Do not set the PRIMARY selection for changes received
-                       from VNC clients.
--noclipboard           Do not poll the CLIPBOARD selection for changes to send
-                       back to clients.  (CLIPBOARD is still set on received
-                       changes, however).
--nosetclipboard        Do not set the CLIPBOARD selection for changes
-                       received from VNC clients.
--seldir string         If direction string is "send", only send the selection
-                       to viewers, and if it is "recv" only receive it from
-                       viewers.  To work around apps setting the selection
-                       too frequently and messing up the other end.  You can
-                       actually supply a comma separated list of directions,
-                       including "debug" to turn on debugging output.
-
--cursor [mode]         Sets how the pointer cursor shape (little icon at the
--nocursor              mouse pointer) should be handled.  The "mode" string
-                       is optional and is described below.  The default
-                       is to show some sort of cursor shape(s).  How this
-                       is done depends on the VNC viewer and the X server.
-                       Use -nocursor to disable cursor shapes completely.
-
-                       Some VNC viewers support the TightVNC CursorPosUpdates
-                       and CursorShapeUpdates extensions (cuts down on
-                       network traffic by not having to send the cursor image
-                       every time the pointer is moved), in which case these
-                       extensions are used (see -nocursorshape and -nocursorpos
-                       below to disable).  For other viewers the cursor shape
-                       is written directly to the framebuffer every time the
-                       pointer is moved or changed and gets sent along with
-                       the other framebuffer updates.  In this case, there
-                       will be some lag between the vnc viewer pointer and
-                       the remote cursor position.
-
-                       If the X display supports retrieving the cursor shape
-                       information from the X server, then the default is
-                       to use that mode.  On Solaris this can be done with
-                       the SUN_OVL extension using -overlay (see also the
-                       -overlay_nocursor option).  A similar overlay scheme
-                       is used on IRIX.  Xorg (e.g. Linux) and recent Solaris
-                       Xsun servers support the XFIXES extension to retrieve
-                       the exact cursor shape from the X server.  If XFIXES
-                       is present it is preferred over Overlay and is used by
-                       default (see -noxfixes below).  This can be disabled
-                       with -nocursor, and also some values of the "mode"
-                       option below.
-
-                       Note that under XFIXES cursors with transparency (alpha
-                       channel) will usually not be exactly represented and one
-                       may find Overlay preferable.  See also the -alphacut
-                       and -alphafrac options below as fudge factors to try
-                       to improve the situation for cursors with transparency
-                       for a given theme.
-
-                       The "mode" string can be used to fine-tune the
-                       displaying of cursor shapes.  It can be used the
-                       following ways:
-
-                       "-cursor arrow" - just show the standard arrow
-                       nothing more or nothing less.
-
-                       "-cursor none" - same as "-nocursor"
-
-                       "-cursor X" - when the cursor appears to be on the
-                       root window, draw the familiar X shape.  Some desktops
-                       such as GNOME cover up the root window completely,
-                       and so this will not work, try "X1", etc, to try to
-                       shift the tree depth.  On high latency links or slow
-                       machines there will be a time lag between expected and
-                       the actual cursor shape.
-
-                       "-cursor some" - like "X" but use additional
-                       heuristics to try to guess if the window should have
-                       a windowmanager-like resizer cursor or a text input
-                       I-beam cursor.  This is a complete hack, but may be
-                       useful in some situations because it provides a little
-                       more feedback about the cursor shape.
-
-                       "-cursor most" - try to show as many cursors as
-                       possible.  Often this will only be the same as "some"
-                       unless the display has overlay visuals or XFIXES
-                       extensions available.  On Solaris and IRIX if XFIXES
-                       is not available, -overlay mode will be attempted.
-
--cursor_drag           Show cursor shape changes even when the mouse is being
-                       dragged with a mouse button down.  This is useful if you
-                       want to be able to see Drag-and-Drop cursor icons, etc.
-
--arrow n               Choose an alternate "arrow" cursor from a set of
-                       some common ones.  n can be 1 to 6.  Default is: 1
-                       Ignored when in XFIXES cursor-grabbing mode.
-
--noxfixes              Do not use the XFIXES extension to draw the exact cursor
-                       shape even if it is available.
-
-                       Note: To work around a crash in Xorg 1.5 and later
-                       some people needed to use -noxfixes.  The Xorg crash
-                       occurred right after a Display Manager (e.g. GDM) login.
-                       Starting with x11vnc 0.9.9 it tries to automatically
-                       avoid using XFIXES until it is sure a window manager
-                       is running.  See the -reopen option for more info and
-                       how to use X11VNC_AVOID_WINDOWS=never to disable it.
-
--alphacut n            When using the XFIXES extension for the cursor shape,
-                       cursors with transparency will not usually be displayed
-                       exactly (but opaque ones will).  This option sets n as
-                       a cutoff for cursors that have transparency ("alpha
-                       channel" with values ranging from 0 to 255) Any cursor
-                       pixel with alpha value less than n becomes completely
-                       transparent.  Otherwise the pixel is completely opaque.
-                       Default 240
-
--alphafrac fraction    With the threshold in -alphacut some cursors will become
-                       almost completely transparent because their alpha values
-                       are not high enough.  For those cursors adjust the
-                       alpha threshold until fraction of the non-zero alpha
-                       channel pixels become opaque.  Default 0.33
--alpharemove           By default, XFIXES cursors pixels with transparency have
-                       the alpha factor multiplied into the RGB color values
-                       (i.e. that corresponding to blending the cursor with a
-                       black background).  Specify this option to remove the
-                       alpha factor. (useful for light colored semi-transparent
-                       cursors).
--noalphablend          In XFIXES mode do not send cursor alpha channel data
-                       to LibVNCServer.  The default is to send it.  The
-                       alphablend effect will only be visible in -nocursorshape
-                       mode or for clients with cursorshapeupdates turned
-                       off. (However there is a hack for 32bpp with depth 24,
-                       it uses the extra 8 bits to store cursor transparency
-                       for use with a hacked vncviewer that applies the
-                       transparency locally.  See the FAQ for more info).
-
--nocursorshape         Do not use the TightVNC CursorShapeUpdates extension
-                       even if clients support it.  See -cursor above.
--cursorpos             Option -cursorpos enables sending the X cursor position
--nocursorpos           back to all vnc clients that support the TightVNC
-                       CursorPosUpdates extension.  Other clients will be able
-                       to see the pointer motions. Default: -cursorpos
--xwarppointer          Move the pointer with XWarpPointer(3X) instead of
--noxwarppointer        the XTEST extension.  Use this as a workaround
-                       if the pointer motion behaves incorrectly, e.g.
-                       on touchscreens or other non-standard setups.
-
-                       It is also sometimes needed on XINERAMA displays and is
-                       enabled by default if XINERAMA is found to be active.
-                       To prevent this, use -noxwarppointer.
-
--always_inject         Even if there is no displacement (dx = dy = 0) for a
-                       VNC mouse event force the pointer to the indicated x,y
-                       position anyway.  Recent (2009) gui toolkits (gnome)
-                       have problems with x11vnc's original mouse input
-                       injection method.  So x11vnc's mouse input injection
-                       method has been modified.  To regain the OLD behavior
-                       use this option: -always_inject.  Then x11vnc will
-                       always force positioning the mouse to the x,y position
-                       even if that position has not changed since the previous
-                       VNC input event.
-
-                       The first place this problem was noticed was in gnome
-                       terminal: if you pressed and released mouse button 3, a
-                       menu was posted and then its first element 'New Terminal
-                       Window' was activated.  This was because x11vnc injected
-                       the mouse position twice: once on ButtonPress and again
-                       on ButtonRelease.  The toolkit interpreted the 2nd one
-                       as mouse motion even though the mouse hadn't moved.
-                       So now by default x11vnc tries to avoid injecting the
-                       2nd one.
-
-                       Note that with the new default x11vnc will be oblivious
-                       to applications moving the pointer (warping) or the
-                       user at the physical display moving it.  So it might,
-                       e.g., inject ButtonRelease at the wrong position.
-                       If this (or similar scenarios) causes problems in your
-                       environment, specify -always_inject for the old method.
-
--buttonmap string      String to remap mouse buttons.  Format: IJK-LMN, this
-                       maps buttons I -> L, etc., e.g.  -buttonmap 13-31
-
-                       Button presses can also be mapped to keystrokes: replace
-                       a button digit on the right of the dash with :<sym>:
-                       or :<sym1>+<sym2>: etc. for multiple keys. For example,
-                       if the viewing machine has a mouse-wheel (buttons 4 5)
-                       but the x11vnc side does not, these will do scrolls:
-                              -buttonmap 12345-123:Prior::Next:
-                              -buttonmap 12345-123:Up+Up+Up::Down+Down+Down:
-
-                       See <X11/keysymdef.h> header file for a list of Keysyms,
-                       or use the xev(1) program.  Note: mapping of button
-                       clicks to Keysyms may not work if -modtweak or -xkb is
-                       needed for the Keysym.
-
-                       If you include a modifier like "Shift_L" the
-                       modifier's up/down state is toggled, e.g. to send
-                       "The" use :Shift_L+t+Shift_L+h+e: (the 1st one is
-                       shift down and the 2nd one is shift up). (note: the
-                       initial state of the modifier is ignored and not reset)
-                       To include button events use "Button1", ... etc.
-
-                       -buttonmap currently does not work on MacOSX console
-                       or in -rawfb mode.
-
-                       Workaround: use -buttonmap IJ...-LM...=n to limit the
-                       number of mouse buttons to n, e.g. 123-123=3.  This will
-                       prevent x11vnc from crashing if the X server reports
-                       there are 5 buttons (4/5 scroll wheel), but there are
-                       only really 3.
-
--nodragging            Do not update the display during mouse dragging events
-                       (mouse button held down).  Greatly improves response on
-                       slow setups, but you lose all visual feedback for drags,
-                       text selection, and some menu traversals.  It overrides
-                       any -pointer_mode setting.
-
--ncache n              Client-side caching scheme.  Framebuffer memory "n"
-                       (an integer) times that of the full display is allocated
-                       below the actual framebuffer to cache screen contents
-                       for rapid retrieval.  So a W x H frambuffer is expanded
-                       to a W x (n+1)*H one.  Use 0 to disable.
-
-                       The "n" is actually optional, the default is 10.
-
-                       For this and the other -ncache* options below you can
-                       abbreviate "-ncache" with "-nc".  Also, "-nonc"
-                       is the same as "-ncache 0"
-
-                       This is an experimental option, currently implemented in
-                       an awkward way in that in the VNC Viewer you can see the
-                       pixel cache contents if you scroll down, etc.  So you
-                       will have to set things up so you can't see that region.
-                       If this method is successful, the changes required for
-                       clients to do this less awkwardly will be investigated.
-
-                       The SSVNC viewer does a good job at automatically hiding
-                       the pixel cache region.  Or use SSVNC's -ycrop option
-                       to explicitly hide the region.
-
-                       Note that this mode consumes a huge amount of memory,
-                       both on the x11vnc server side and on the VNC Viewer
-                       side.  If n=2 then the amount of RAM used is roughly
-                       tripled for both x11vnc and the VNC Viewer.  As a rule
-                       of thumb, note that 1280x1024 at depth 24 is about 5MB
-                       of pixel data.
-
-                       For reasonable response when cycling through 4 to 6
-                       large (e.g. web browser) windows a value n of 6 to 12
-                       is recommended. (that's right: ~10X more memory...)
-
-                       Because of the way window backingstore and saveunders
-                       are implemented, n must be even.  It will be incremented
-                       by 1 if it is not.
-
-                       This mode also works for native MacOS X, but may not
-                       be as effective as the X version.  This is due to a
-                       number of things, one is the drop-shadow compositing
-                       that leaves extra areas that need to be repaired (see
-                       -ncache_pad).  Another is the window iconification
-                       animations need to be avoided (see -macicontime).
-                       It appears the that the 'Scale' animation mode gives
-                       better results than the 'Genie' one.  Also, window event
-                       detection not as accurate as the X version.
-
--ncache_cr             In -ncache mode, try to do copyrect opaque window
-                       moves/drags instead of wireframes (this can induce
-                       painting errors).  The wireframe will still be used when
-                       moving a window whose save-unders has not yet been set
-                       or has been invalidated.
-
-                       Some VNC Viewers provide better response than others
-                       with this option.  On Unix, realvnc viewer gives
-                       smoother drags than tightvnc viewer.  Response may also
-                       be choppy if the server side machine is too slow.
-
-                       Sometimes on very slow modem connections, this actually
-                       gives an improvement because no pixel data at all
-                       (not even the box animation) is sent during the drag.
-
--ncache_no_moveraise   In -ncache mode, do not assume that moving a window
-                       will cause the window manager to raise it to the top
-                       of the stack.  The default is to assume it does, and
-                       so at the beginning of any wireframe, etc, window moves
-                       the window will be pushed to top in the VNC viewer.
-
--ncache_no_dtchange    In -ncache mode, do not try to guess when the desktop
-                       (viewport) changes to another one (i.e. another
-                       workarea).  The default is to try to guess and when
-                       detected try to make the transistion more smoothly.
-
--ncache_no_rootpixmap  In -ncache mode, do not try to snapshot the desktop
-                       background to use in guessing or reconstructing window
-                       save-unders.
-
--ncache_keep_anims     In -ncache mode, do not try to disable window
-                       manager animations and other effects (that usually
-                       degrade ncache performance or cause painting errors).
-                       The default is to try to disable them on KDE (but not
-                       GNOME) when VNC clients are connected.
-
-                       For other window managers or desktops that provide
-                       animations, effects, compositing, translucency,
-                       etc. that interfere with the -ncache method you will
-                       have to disable them manually.
-
--ncache_old_wm         In -ncache mode, enable some heuristics for old style
-                       window managers such as fvwm and twm.
-
--ncache_pad n          In -ncache mode, pad each window with n pixels for the
-                       caching rectangles.  This can be used to try to improve
-                       the situation with dropshadows or other compositing
-                       (e.g. MacOS X window manager), although it could make
-                       things worse.  The default is 0 on Unix and 24 on
-                       MacOS X.
--debug_ncache          Turn on debugging and profiling output under -ncache.
-
--wireframe [str]       Try to detect window moves or resizes when a mouse
--nowireframe           button is held down and show a wireframe instead of
-                       the full opaque window.  This is based completely on
-                       heuristics and may not always work: it depends on your
-                       window manager and even how you move things around.
-                       See -pointer_mode below for discussion of the "bogging
-                       down" problem this tries to avoid.
-                       Default: -wireframe
-
-                       Shorter aliases:  -wf [str]  and -nowf
-
-                       The value "str" is optional and, of course, is
-                       packed with many tunable parameters for this scheme:
-
-                       Format: shade,linewidth,percent,T+B+L+R,mod,t1+t2+t3+t4
-                       Default: 0xff,2,0,32+8+8+8,all,0.15+0.30+5.0+0.125
-
-                       If you leave nothing between commas: ",," the default
-                       value is used.  If you don't specify enough commas,
-                       the trailing parameters are set to their defaults.
-
-                       "shade" indicate the "color" for the wireframe,
-                       usually a greyscale: 0-255, however for 16 and 32bpp you
-                       can specify an rgb.txt X color (e.g. "dodgerblue") or
-                       a value > 255 is treated as RGB (e.g. red is 0xff0000).
-                       "linewidth" sets the width of the wireframe in pixels.
-                       "percent" indicates to not apply the wireframe scheme
-                       to windows with area less than this percent of the
-                       full screen.
-
-                       "T+B+L+R" indicates four integers for how close in
-                       pixels the pointer has to be from the Top, Bottom, Left,
-                       or Right edges of the window to consider wireframing.
-                       This is a speedup to quickly exclude a window from being
-                       wireframed: set them all to zero to not try the speedup
-                       (scrolling and selecting text will likely be slower).
-
-                       "mod" specifies if a button down event in the
-                       interior of the window with a modifier key (Alt, Shift,
-                       etc.) down should indicate a wireframe opportunity.
-                       It can be "0" or "none" to skip it, "1" or "all"
-                       to apply it to any modifier, or "Shift", "Alt",
-                       "Control", "Meta", "Super", or "Hyper" to only
-                       apply for that type of modifier key.
-
-                       "t1+t2+t3+t4" specify four floating point times in
-                       seconds: t1 is how long to wait for the pointer to move,
-                       t2 is how long to wait for the window to start moving
-                       or being resized (for some window managers this can be
-                       rather long), t3 is how long to keep a wireframe moving
-                       before repainting the window. t4 is the minimum time
-                       between sending wireframe "animations".  If a slow
-                       link is detected, these values may be automatically
-                       changed to something better for a slow link.
-
--nowireframelocal      By default, mouse motion and button presses of a
-                       user sitting at the LOCAL display are monitored for
-                       wireframing opportunities (so that the changes will be
-                       sent efficiently to the VNC clients).  Use this option
-                       to disable this behavior.
-
--wirecopyrect mode     Since the -wireframe mechanism evidently tracks moving
--nowirecopyrect        windows accurately, a speedup can be obtained by
-                       telling the VNC viewers to locally copy the translated
-                       window region.  This is the VNC CopyRect encoding:
-                       the framebuffer update doesn't need to send the actual
-                       new image data.
-
-                       Shorter aliases:  -wcr [mode]  and -nowcr
-
-                       "mode" can be "never" (same as -nowirecopyrect)
-                       to never try the copyrect, "top" means only do it if
-                       the window was not covered by any other windows, and
-                       "always" means to translate the orginally unobscured
-                       region (this may look odd as the remaining pieces come
-                       in, but helps on a slow link).  Default: "always"
-
-                       Note: there can be painting errors or slow response
-                       when using -scale so you may want to disable CopyRect
-                       in this case "-wirecopyrect never" on the command
-                       line or by remote-control.  Or you can also use the
-                       "-scale xxx:nocr" scale option.
-
--debug_wireframe       Turn on debugging info printout for the wireframe
-                       heuristics.  "-dwf" is an alias.  Specify multiple
-                       times for more output.
-
--scrollcopyrect mode   Like -wirecopyrect, but use heuristics to try to guess
--noscrollcopyrect      if a window has scrolled its contents (either vertically
-                       or horizontally).  This requires the RECORD X extension
-                       to "snoop" on X applications (currently for certain
-                       XCopyArea and XConfigureWindow X protocol requests).
-                       Examples: Hitting <Return> in a terminal window when the
-                       cursor was at the bottom, the text scrolls up one line.
-                       Hitting <Down> arrow in a web browser window, the web
-                       page scrolls up a small amount.  Or scrolling with a
-                       scrollbar or mouse wheel.
-
-                       Shorter aliases:  -scr [mode]  and -noscr
-
-                       This scheme will not always detect scrolls, but when
-                       it does there is a nice speedup from using the VNC
-                       CopyRect encoding (see -wirecopyrect).  The speedup
-                       is both in reduced network traffic and reduced X
-                       framebuffer polling/copying.  On the other hand, it may
-                       induce undesired transients (e.g. a terminal cursor
-                       being scrolled up when it should not be) or other
-                       painting errors (window tearing, bunching-up, etc).
-                       These are automatically repaired in a short period
-                       of time.  If this is unacceptable disable the feature
-                       with -noscrollcopyrect.
-
-                       Screen clearing kludges:  for testing at least, there
-                       are some "magic key sequences" (must be done in less
-                       than 1 second) to aid repairing painting errors that
-                       may be seen when using this mode:
-
-                       3 Alt_L's   in a row: resend whole screen,
-                       4 Alt_L's   in a row: reread and resend whole screen,
-                       3 Super_L's in a row: mark whole screen for polling,
-                       4 Super_L's in a row: reset RECORD context,
-                       5 Super_L's in a row: try to push a black screen
-
-                       note: Alt_L is the Left "Alt" key (a single key)
-                       Super_L is the Left "Super" key (Windows flag).
-                       Both of these are modifier keys, and so should not
-                       generate characters when pressed by themselves.  Also,
-                       your VNC viewer may have its own refresh hot-key
-                       or button.
-
-                       "mode" can be "never" (same as -noscrollcopyrect)
-                       to never try the copyrect, "keys" means to try it
-                       in response to keystrokes only, "mouse" means to
-                       try it in response to mouse events only, "always"
-                       means to do both. Default: "always"
-
-                       Note: there can be painting errors or slow response
-                       when using -scale so you may want to disable CopyRect
-                       in this case "-scrollcopyrect never" on the command
-                       line or by remote-control.  Or you can also use the
-                       "-scale xxx:nocr" scale option.
-
--scr_area n            Set the minimum area in pixels for a rectangle
-                       to be considered for the -scrollcopyrect detection
-                       scheme.  This is to avoid wasting the effort on small
-                       rectangles that would be quickly updated the normal way.
-                       E.g. suppose an app updated the position of its skinny
-                       scrollbar first and then shifted the large panel
-                       it controlled.  We want to be sure to skip the small
-                       scrollbar and get the large panel. Default: 60000

--scr_skip list         Skip scroll detection for applications matching
-                       the comma separated list of strings in "list".
-                       Some applications implement their scrolling in
-                       strange ways where the XCopyArea, etc, also applies
-                       to invisible portions of the window: if we CopyRect
-                       those areas it looks awful during the scroll and
-                       there may be painting errors left after the scroll.
-                       Soffice.bin is the worst known offender.
-
-                       Use "##" to denote the start of the application class
-                       (e.g. "##XTerm") and "++" to denote the start
-                       of the application instance name (e.g. "++xterm").
-                       The string your list is matched against is of the form
-                       "^^WM_NAME##Class++Instance<same-for-any-subwindows>"
-                       The "xlsclients -la" command will provide this info.
-
-                       If a pattern is prefixed with "KEY:" it only applies
-                       to Keystroke generated scrolls (e.g. Up arrow).  If it
-                       is prefixed with "MOUSE:" it only applies to Mouse
-                       induced scrolls (e.g. dragging on a scrollbar).
-                       Default: ##Soffice.bin,##StarOffice,##OpenOffice
-
--scr_inc list          Opposite of -scr_skip: this list is consulted first
-                       and if there is a match the window will be monitored
-                       via RECORD for scrolls irrespective of -scr_skip.
-                       Use -scr_skip '*' to skip anything that does not match
-                       your -scr_inc.  Use -scr_inc '*' to include everything.
-
--scr_keys list         For keystroke scroll detection, only apply the RECORD
-                       heuristics to the comma separated list of keysyms in
-                       "list".  You may find the RECORD overhead for every
-                       one of your keystrokes disrupts typing too much, but you
-                       don't want to turn it off completely with "-scr mouse"
-                       and -scr_parms does not work or is too confusing.
-
-                       The listed keysyms can be numeric or the keysym
-                       names in the <X11/keysymdef.h> header file or from the
-                       xev(1) program.  Example: "-scr_keys Up,Down,Return".
-                       One probably wants to have application specific lists
-                       (e.g. for terminals, etc) but that is too icky to think
-                       about for now...
-
-                       If "list" begins with the "-" character the list
-                       is taken as an exclude list: all keysyms except those
-                       list will be considered.  The special string "builtin"
-                       expands to an internal list of keysyms that are likely
-                       to cause scrolls.  BTW, by default modifier keys,
-                       Shift_L, Control_R, etc, are skipped since they almost
-                       never induce scrolling by themselves.
-
--scr_term list         Yet another cosmetic kludge.  Apply shell/terminal
-                       heuristics to applications matching comma separated
-                       list (same as for -scr_skip/-scr_inc).  For example an
-                       annoying transient under scroll detection is if you
-                       hit Enter in a terminal shell with full text window,
-                       the solid text cursor block will be scrolled up.
-                       So for a short time there are two (or more) block
-                       cursors on the screen.  There are similar scenarios,
-                       (e.g. an output line is duplicated).
-
-                       These transients are induced by the approximation of
-                       scroll detection (e.g. it detects the scroll, but not
-                       the fact that the block cursor was cleared just before
-                       the scroll).  In nearly all cases these transient errors
-                       are repaired when the true X framebuffer is consulted
-                       by the normal polling.  But they are distracting, so
-                       what this option provides is extra "padding" near the
-                       bottom of the terminal window: a few extra lines near
-                       the bottom will not be scrolled, but rather updated
-                       from the actual X framebuffer.  This usually reduces
-                       the annoying artifacts.  Use "none" to disable.
-                       Default: "term"
-
--scr_keyrepeat lo-hi   If a key is held down (or otherwise repeats rapidly) and
-                       this induces a rapid sequence of scrolls (e.g. holding
-                       down an Arrow key) the "scrollcopyrect" detection
-                       and overhead may not be able to keep up.  A time per
-                       single scroll estimate is performed and if that estimate
-                       predicts a sustainable scrollrate of keys per second
-                       between "lo" and "hi" then repeated keys will be
-                       DISCARDED to maintain the scrollrate. For example your
-                       key autorepeat may be 25 keys/sec, but for a large
-                       window or slow link only 8 scrolls per second can be
-                       sustained, then roughly 2 out of every 3 repeated keys
-                       will be discarded during this period. Default: "4-20"
-
--scr_parms string      Set various parameters for the scrollcopyrect mode.
-                       The format is similar to that for -wireframe and packed
-                       with lots of parameters:
-
-                       Format: T+B+L+R,t1+t2+t3,s1+s2+s3+s4+s5
-                       Default: 0+64+32+32,0.02+0.10+0.9,0.03+0.06+0.5+0.1+5.0
-
-                       If you leave nothing between commas: ",," the default
-                       value is used.  If you don't specify enough commas,
-                       the trailing parameters are set to their defaults.
-
-                       "T+B+L+R" indicates four integers for how close in
-                       pixels the pointer has to be from the Top, Bottom, Left,
-                       or Right edges of the window to consider scrollcopyrect.
-                       If -wireframe overlaps it takes precedence.  This is a
-                       speedup to quickly exclude a window from being watched
-                       for scrollcopyrect: set them all to zero to not try
-                       the speedup (things like selecting text will likely
-                       be slower).
-
-                       "t1+t2+t3" specify three floating point times in
-                       seconds that apply to scrollcopyrect detection with
-                       *Keystroke* input: t1 is how long to wait after a key
-                       is pressed for the first scroll, t2 is how long to keep
-                       looking after a Keystroke scroll for more scrolls.
-                       t3 is how frequently to try to update surrounding
-                       scrollbars outside of the scrolling area (0.0 to
-                       disable)
-
-                       "s1+s2+s3+s4+s5" specify five floating point times
-                       in seconds that apply to scrollcopyrect detection with
-                       *Mouse* input: s1 is how long to wait after a mouse
-                       button is pressed for the first scroll, s2 is how long
-                       to keep waiting for additional scrolls after the first
-                       Mouse scroll was detected.  s3 is how frequently to
-                       try to update surrounding scrollbars outside of the
-                       scrolling area (0.0 to disable).  s4 is how long to
-                       buffer pointer motion (to try to get fewer, bigger
-                       mouse scrolls). s5 is the maximum time to spend just
-                       updating the scroll window without updating the rest
-                       of the screen.
-
--fixscreen string      Periodically "repair" the screen based on settings
-                       in "string".  Hopefully you won't need this option,
-                       it is intended for cases when the -scrollcopyrect or
-                       -wirecopyrect features leave too many painting errors,
-                       but it can be used for any scenario.  This option
-                       periodically performs costly operations and so
-                       interactive response may be reduced when it is on.
-                       You can use 3 Alt_L's (the Left "Alt" key) taps in
-                       a row (as described under -scrollcopyrect) instead to
-                       manually request a screen repaint when it is needed.
-
-                       "string" is a comma separated list of one or more of
-                       the following: "V=t", "C=t", "X=t", and "8=t".
-                       In these "t" stands for a time in seconds (it is
-                       a floating point even though one should usually use
-                       values > 2 to avoid wasting resources).  V sets how
-                       frequently the entire screen should be sent to viewers
-                       (it is like the 3 Alt_L's).  C sets how long to wait
-                       after a CopyRect to repaint the full screen.  X sets
-                       how frequently to reread the full X11 framebuffer from
-                       the X server and push it out to connected viewers.
-                       Use of X should be rare, please report a bug if you
-                       find you need it. 8= applies only for -8to24 mode: it
-                       sets how often the non-default visual regions of the
-                       screen (e.g. 8bpp windows) are refreshed.  Examples:
-                       -fixscreen V=10 -fixscreen C=10
-
--debug_scroll          Turn on debugging info printout for the scroll
-                       heuristics.  "-ds" is an alias.  Specify it multiple
-                       times for more output.
-
--noxrecord             Disable any use of the RECORD extension.  This is
-                       currently used by the -scrollcopyrect scheme and to
-                       monitor X server grabs.
-
--grab_buster           Some of the use of the RECORD extension can leave a
--nograb_buster         tiny window for XGrabServer deadlock.  This is only if
-                       the whole-server grabbing application expects mouse or
-                       keyboard input before releasing the grab.  It is usually
-                       a window manager that does this.  x11vnc takes care to
-                       avoid the problem, but if caught x11vnc will freeze.
-                       Without -grab_buster, the only solution is to go the
-                       physical display and give it some input to satisfy the
-                       grabbing app.  Or manually kill and restart the window
-                       manager if that is feasible.  With -grab_buster, x11vnc
-                       will fork a helper thread and if x11vnc appears to be
-                       stuck in a grab after a period of time (20-30 sec) then
-                       it will inject some user input: button clicks, Escape,
-                       mouse motion, etc to try to break the grab.  If you
-                       experience a lot of grab deadlock, please report a bug.
-
--debug_grabs           Turn on debugging info printout with respect to
-                       XGrabServer() deadlock for -scrollcopyrect mode.
-
--debug_sel             Turn on debugging info printout with respect to
-                       PRIMARY, CLIPBOARD, and CUTBUFFER0 selections.
-
--pointer_mode n        Various pointer motion update schemes. "-pm" is
-                       an alias.  The problem is pointer motion can cause
-                       rapid changes on the screen: consider the rapid
-                       changes when you drag a large window around opaquely.
-                       Neither x11vnc's screen polling and vnc compression
-                       routines nor the bandwidth to the vncviewers can keep
-                       up these rapid screen changes: everything will bog down
-                       when dragging or scrolling.  So a scheme has to be used
-                       to "eat" much of that pointer input before re-polling
-                       the screen and sending out framebuffer updates. The
-                       mode number "n" can be 0 to 4 and selects one of
-                       the schemes desribed below.
-
-                       Note that the -wireframe and -scrollcopyrect modes
-                       complement -pointer_mode by detecting (and improving)
-                       certain periods of "rapid screen change".
-
-                       n=0: does the same as -nodragging. (all screen polling
-                       is suspended if a mouse button is pressed.)
-
-                       n=1: was the original scheme used to about Jan 2004:
-                       it basically just skips -input_skip keyboard or pointer
-                       events before repolling the screen.
-
-                       n=2 is an improved scheme: by watching the current rate
-                       of input events it tries to detect if it should try to
-                       "eat" additional pointer events before continuing.
-
-                       n=3 is basically a dynamic -nodragging mode: it detects
-                       when the mouse motion has paused and then refreshes
-                       the display.
-
-                       n=4 attempts to measures network rates and latency,
-                       the video card read rate, and how many tiles have been
-                       changed on the screen.  From this, it aggressively tries
-                       to push screen "frames" when it decides it has enough
-                       resources to do so.  NOT FINISHED.
-
-                       The default n is 2. Note that modes 2, 3, 4 will skip
-                       -input_skip keyboard events (but it will not count
-                       pointer events).  Also note that these modes are not
-                       available in -threads mode which has its own pointer
-                       event handling mechanism.
-
-                       To try out the different pointer modes to see which
-                       one gives the best response for your usage, it is
-                       convenient to use the remote control function, for
-                       example "x11vnc -R pm:4" or the tcl/tk gui (Tuning ->
-                       pointer_mode -> n).
-
--input_skip n          For the pointer handling when non-threaded: try to
-                       read n user input events before scanning display. n < 0
-                       means to act as though there is always user input.
-                       Default: 10
-
--allinput              Have x11vnc read and process all available client input
-                       before proceeding.
-
--input_eagerly         Similar to -allinput but use the handleEventsEagerly
-                       mechanism built into LibVNCServer.
-
--speeds rd,bw,lat      x11vnc tries to estimate some speed parameters that
-                       are used to optimize scheduling (e.g. -pointer_mode
-                       4, -wireframe, -scrollcopyrect) and other things.
-                       Use the -speeds option to set these manually.
-                       The triple "rd,bw,lat" corresponds to video h/w
-                       read rate in MB/sec, network bandwidth to clients in
-                       KB/sec, and network latency to clients in milliseconds,
-                       respectively.  If a value is left blank, e.g. "-speeds
-                       ,100,15", then the internal scheme is used to estimate
-                       the empty value(s).

-                       Typical PC video cards have read rates of 5-10 MB/sec.
-                       If the framebuffer is in main memory instead of video
-                       h/w (e.g. SunRay, shadowfb, dummy driver, Xvfb), the
-                       read rate may be much faster.  "x11perf -getimage500"
-                       can be used to get a lower bound (remember to factor
-                       in the bytes per pixel).  It is up to you to estimate
-                       the network bandwith and latency to clients.  For the
-                       latency the ping(1) command can be used.
-
-                       For convenience there are some aliases provided,
-                       e.g. "-speeds modem".  The aliases are: "modem" for
-                       6,4,200; "dsl" for 6,100,50; and "lan" for 6,5000,1
-
--wmdt string           For some features, e.g. -wireframe and -scrollcopyrect,
-                       x11vnc has to work around issues for certain window
-                       managers or desktops (currently kde and xfce).
-                       By default it tries to guess which one, but it can
-                       guess incorrectly.  Use this option to indicate which
-                       wm/dt.  "string" can be "gnome", "kde", "cde",
-                       "xfce", or "root" (classic X wm).  Anything else
-                       is interpreted as "root".
-
--debug_pointer         Print debugging output for every pointer event.
--debug_keyboard        Print debugging output for every keyboard event.
-                       Same as -dp and -dk, respectively.  Use multiple
-                       times for more output.
-
--defer time            Time in ms to delay sending updates to connected clients
-                       (deferUpdateTime)  Default: 20
-
--wait time             Time in ms to pause between screen polls.  Used to cut
-                       down on load.  Default: 20
-
--extra_fbur n          Perform extra FrameBufferUpdateRequests checks to
-                       try to be in better sync with the client's requests.
-                       What this does is perform extra polls of the client
-                       socket at critical times (before '-defer' and '-wait'
-                       calls.)  The default is n=1.  Set to a larger number to
-                       insert more checks or set to n=0 to disable.  A downside
-                       of these extra calls is that more mouse input may be
-                       processed than desired.
-
--wait_ui factor        Factor by which to cut the -wait time if there
-                       has been recent user input (pointer or keyboard).
-                       Improves response, but increases the load whenever you
-                       are moving the mouse or typing.  Default: 2.00
--setdefer n            When the -wait_ui mechanism cuts down the wait time ms,
-                       set the defer time to the same ms value. n=1 to enable,
-                       0 to disable, and -1 to set defer to 0 (no delay).
-                       Similarly, 2 and -2 indicate 'urgent_update' mode should
-                       be used to push the updates even sooner.  Default: 1
--nowait_bog            Do not detect if the screen polling is "bogging down"
-                       and sleep more.  Some activities with no user input can
-                       slow things down a lot: consider a large terminal window
-                       with a long build running in it continuously streaming
-                       text output.  By default x11vnc will try to detect this
-                       (3 screen polls in a row each longer than 0.25 sec with
-                       no user input), and sleep up to 1.5 secs to let things
-                       "catch up".  Use this option to disable that detection.
--slow_fb time          Floating point time in seconds to delay all screen
-                       polling.  For special purpose usage where a low frame
-                       rate is acceptable and desirable, but you want the
-                       user input processed at the normal rate so you cannot
-                       use -wait.
--xrefresh time         Floating point time in seconds to indicate how often to
-                       do the equivalent of xrefresh(1) to force all windows
-                       (in the viewable area if -id, -sid, or -clip is used)
-                       to repaint themselves.  Use this only if applications
-                       misbehave by not repainting themselves properly.
-                       See also -noxdamage.
--nap                   Monitor activity and if it is low take longer naps
--nonap                 between screen polls to really cut down load when idle.
-                       Default: take naps
--sb time               Time in seconds after NO activity (e.g. screen blank)
-                       to really throttle down the screen polls (i.e. sleep
-                       for about 1.5 secs). Use 0 to disable.  Default: 60
-                       Set the env. var. X11VNC_SB_FACTOR to scale it.
-
--readtimeout n         Set LibVNCServer rfbMaxClientWait to n seconds. On
-                       slow links that take a long time to paint the first
-                       screen LibVNCServer may hit the timeout and drop the
-                       connection.  Default: 20 seconds.
--ping n                Send a 1x1 framebuffer update to all clients every n
-                       seconds (e.g. to try to keep a network connection alive)
-
--nofbpm                If the system supports the FBPM (Frame Buffer Power
--fbpm                  Management) extension (i.e. some Sun systems), then
-                       prevent the video h/w from going into a reduced power
-                       state when VNC clients are connected.
-
-                       FBPM capable video h/w save energy when the workstation
-                       is idle by going into low power states (similar to DPMS
-                       for monitors).  This interferes with x11vnc's polling
-                       of the framebuffer data.
-
-                       "-nofbpm" means prevent FBPM low power states whenever
-                       VNC clients are connected, while "-fbpm" means to not
-                       monitor the FBPM state at all.  See the xset(1) manpage
-                       for details.  -nofbpm is basically the same as running
-                       "xset fbpm force on" periodically.  Default: -fbpm
-
--nodpms                If the system supports the DPMS (Display Power Managemen
-t
--dpms                  Signaling) extension, then prevent the monitor from
-                       going into a reduced power state when VNC clients
-                       are connected.
-
-                       DPMS reduced power monitor states are a good thing
-                       and you normally want the power down to take place
-                       (usually x11vnc has no problem exporting the display in
-                       this state).  You probably only want to use "-nodpms"
-                       to work around problems with Screen Savers kicking
-                       on in DPMS low power states.  There is known problem
-                       with kdesktop_lock on KDE where the screen saver keeps
-                       kicking in every time user input stops for a second
-                       or two.  Specifying "-nodpms" works around it.
-
-                       "-nodpms" means prevent DPMS low power states whenever
-                       VNC clients are connected, while "-dpms" means to not
-                       monitor the DPMS state at all.  See the xset(1) manpage
-                       for details.  -nodpms is basically the same as running
-                       "xset dpms force on" periodically.  Default: -dpms
-
--forcedpms             If the system supports the DPMS (Display Power
-                       Management Signaling) extension, then try to keep the
-                       monitor in a powered off state.  This is to prevent
-                       nosey people at the physical display from viewing what
-                       is on the screen.  Be sure to lock the screen before
-                       disconnecting.
-
-                       This method is far from bullet proof, e.g. suppose
-                       someone attaches a non-DPMS monitor, or loads the
-                       machine so that there is a gap of time before x11vnc
-                       restores the powered off state?  On many machines if
-                       he floods it with keyboard and mouse input he can see
-                       flashes of what is on the screen before the DPMS off
-                       state is reestablished.  For this to work securely
-                       there would need to be support in the X server to do
-                       this exactly rather than approximately with DPMS.
-
--clientdpms            As -forcedpms but only when VNC clients are connected.
-
--noserverdpms          The UltraVNC ServerInput extension is supported.
-                       This allows the VNC viewer to click a button that will
-                       cause the server (x11vnc) to try to disable keyboard
-                       and mouse input at the physical display and put the
-                       monitor in dpms powered off state.  Use this option to
-                       skip powering off the monitor.
-
--noultraext            Disable the following UltraVNC extensions: SingleWindow
-                       and ServerInput.  The others managed by LibVNCServer
-                       (textchat, 1/n scaling, rfbEncodingUltra) are not.
-
--chatwindow            Place a local UltraVNC chat window on the X11 display
-                       that x11vnc is polling.  That way the person on the VNC
-                       viewer-side can chat with the person at the physical
-                       X11 console. (e.g. helpdesk w/o telephone)
-
-                       For this to work the SSVNC package (version 1.0.21 or
-                       later) MUST BE installed on the system where x11vnc runs
-                       and the 'ssvnc' command must be available in $PATH.
-                       The ssvncviewer is used as a chat window helper.
-                       See http://www.karlrunge.com/x11vnc/ssvnc.html
-
-                       This option implies '-rfbversion 3.6' so as to trick
-                       UltraVNC viewers, otherwise they assume chat is not
-                       available.  To specify a different rfbversion, place
-                       it after the -chatwindow option on the cmdline.
-
-                       See also the remote control 'chaton' and 'chatoff'
-                       actions.  These can also be set from the tkx11vnc GUI.
-
--noxdamage             Do not use the X DAMAGE extension to detect framebuffer
-                       changes even if it is available.  Use -xdamage if your
-                       default is to have it off.
-
-                       x11vnc's use of the DAMAGE extension: 1) significantly
-                       reduces the load when the screen is not changing much,
-                       and 2) detects changed areas (small ones by default)
-                       more quickly.
-
-                       Currently the DAMAGE extension is overly conservative
-                       and often reports large areas (e.g. a whole terminal
-                       or browser window) as damaged even though the actual
-                       changed region is much smaller (sometimes just a few
-                       pixels).  So heuristics were introduced to skip large
-                       areas and use the damage rectangles only as "hints"
-                       for the traditional scanline polling.  The following
-                       tuning parameters are introduced to adjust this
-                       behavior:
-
--xd_area A             Set the largest DAMAGE rectangle area "A" (in
-                       pixels: width * height) to trust as truly damaged:
-                       the rectangle will be copied from the framebuffer
-                       (slow) no matter what.  Set to zero to trust *all*
-                       rectangles. Default: 20000
--xd_mem f              Set how long DAMAGE rectangles should be "remembered",
-                       "f" is a floating point number and is in units of the
-                       scanline repeat cycle time (32 iterations).  The default
-                       (1.0) should give no painting problems. Increase it if
-                       there are problems or decrease it to live on the edge
-                       (perhaps useful on a slow machine).
-
--sigpipe string        Broken pipe (SIGPIPE) handling.  "string" can be
-                       "ignore" or "exit".  For "ignore" LibVNCServer
-                       will handle the abrupt loss of a client and continue,
-                       for "exit" x11vnc will cleanup and exit at the 1st
-                       broken connection.
-
-                       This option is not really needed since LibVNCServer
-                       is doing the correct thing now for quite some time.
-                       However, for convenience you can use it to ignore other
-                       signals, e.g. "-sigpipe ignore:HUP,INT,TERM" in case
-                       that would be useful for some sort of application.
-                       You can also put "exit:.." in the list to have x11vnc
-                       cleanup on the listed signals. "-sig" is an alias
-                       for this option if you don't like the 'pipe'. Example:
-                       -sig ignore:INT,TERM,exit:USR1
-
--threads               Whether or not to use the threaded LibVNCServer
--nothreads             algorithm [rfbRunEventLoop] if libpthread is available.
-                       In this mode new threads (one for input and one
-                       for output) are created to handle each new client.
-                       Default: -nothreads.
-
-                       Thread stability is much improved in version 0.9.8.
-
-                       Multiple clients in threaded mode should be stable
-                       for the ZRLE encoding on all platforms.  The Tight and
-                       Zlib encodings are currently only stable on Linux for
-                       multiple clients.  Compile with -DTLS=__thread if your
-                       OS and compiler and linker support it.
-
-                       For resizes (randr, etc.) set this env. var. to the numb
-er
-                       of milliseconds to sleep: X11VNC_THREADS_NEW_FB_SLEEP
-                       at various places in the do_new_fb() action.  This is to
-                       let various activities settle.  Default is about 500ms.
-
-                       Multiple clients in threaded mode could yield better
-                       performance for 'class-room' broadcasting usage; also in
-                       -appshare broadcast mode.  See also the -reflect option.
-
--fs f                  If the fraction of changed tiles in a poll is greater
-                       than f, the whole screen is updated.  Default: 0.75
--gaps n                Heuristic to fill in gaps in rows or cols of n or
-                       less tiles.  Used to improve text paging.  Default: 4
--grow n                Heuristic to grow islands of changed tiles n or wider
-                       by checking the tile near the boundary.  Default: 3
--fuzz n                Tolerance in pixels to mark a tiles edges as changed.
-                       Default: 2
--debug_tiles           Print debugging output for tiles, fb updates, etc.
-
--snapfb                Instead of polling the X display framebuffer (fb)
-                       for changes, periodically copy all of X display fb
-                       into main memory and examine that copy for changes.
-                       (This setting also applies for non-X -rawfb modes).
-                       Under some circumstances this will improve interactive
-                       response, or at least make things look smoother, but in
-                       others (most!) it will make the response worse.  If the
-                       video h/w fb is such that reading small tiles is very
-                       slow this mode could help.  To keep the "framerate"
-                       up the screen size x bpp cannot be too large.  Note that
-                       this mode is very wasteful of memory I/O resources
-                       (it makes full screen copies even if nothing changes).
-                       It may be of use in video capture-like applications,
-                       webcams, or where window tearing is a problem.
-
--rawfb string          Instead of polling X, poll the memory object specified
-                       in "string".
-
-                       For file polling, to memory map mmap(2) a file use:
-                       "map:/path/to/a/file@WxHxB", with framebuffer Width,
-                       Height, and Bits per pixel.  "mmap:..." is the
-                       same.
-
-                       If there is trouble with mmap, use "file:/..."
-                       for slower lseek(2) based reading.
-
-                       Use "snap:..." to imply -snapfb mode and the "file:"
-                       access (this is for unseekable devices that only provide
-                       the fb all at once, e.g. a video camera provides the
-                       whole frame).
-
-                       For shared memory segments string is of the form:
-                       "shm:N@WxHxB" which specifies a shmid N and with
-                       WxHxB as above.  See shmat(1) and ipcs(1)
-
-                       If you do not supply a type "map" is assumed if
-                       the file exists (see the next paragraphs for some
-                       exceptions to this.)
-
-                       If string is "setup:cmd", then the command "cmd"
-                       is run and the first line from it is read and used
-                       as "string".  This allows initializing the device,
-                       determining WxHxB, etc. These are often done as root
-                       so take care.
-
-                       If the string begins with "video", see the VIDEO4LINUX
-                       discussion below where the device may be queried for
-                       (and possibly set) the framebuffer parameters.
-
-                       If the string begins with "console", "/dev/fb",
-                       "fb", or "vt", see the LINUX CONSOLE discussion
-                       below where the framebuffer device is opened and
-                       keystrokes (and possibly mouse events) are inserted
-                       into the console.
-
-                       If the string begins with "vnc", see the VNC HOST
-                       discussion below where the framebuffer is taken as that
-                       of another remote VNC server.
-
-                       Optional suffixes are ":R/G/B" and "+O" to specify
-                       red, green, and blue masks (in hex) and an offset into
-                       the memory object.  If the masks are not provided x11vnc
-                       guesses them based on the bpp (if the colors look wrong,
-                       you need to provide the masks.)
-
-                       Another optional suffix is the Bytes Per Line which in
-                       some cases is not WxB/8.  Specify it as WxHxB-BPL
-                       e.g. 800x600x16-2048.  This could be a normal width
-                       1024 at 16bpp fb, but only width 800 shows up.
-
-                       So the full format is: mode:file@WxHxB:R/G/B+O-BPL
-
-                       Examples:
-                           -rawfb shm:210337933@800x600x32:ff/ff00/ff0000
-                           -rawfb map:/dev/fb0@1024x768x32
-                           -rawfb map:/tmp/Xvfb_screen0@640x480x8+3232
-                           -rawfb file:/tmp/my.pnm@250x200x24+37
-                           -rawfb file:/dev/urandom@128x128x8
-                           -rawfb snap:/dev/video0@320x240x24 -24to32
-                           -rawfb video0
-                           -rawfb video -pipeinput VID
-                           -rawfb console
-                           -rawfb vt2
-                           -rawfb vnc:somehost:0
-
-                       (see ipcs(1) and fbset(1) for the first two examples)
-
-                       In general all user input is discarded by default (see
-                       the -pipeinput option for how to use a helper program
-                       to insert).  Most of the X11 (screen, keyboard, mouse)
-                       options do not make sense and many will cause this
-                       mode to crash, so please think twice before setting or
-                       changing them in a running x11vnc.
-
-                       If you DO NOT want x11vnc to close the X DISPLAY in
-                       rawfb mode, prepend a "+" e.g. +file:/dev/fb0...
-                       Keeping the display open enables the default
-                       remote-control channel, which could be useful.
-                       Alternatively, if you specify -noviewonly, then the
-                       mouse and keyboard input are STILL sent to the X
-                       display, this usage should be very rare, i.e. doing
-                       something strange with /dev/fb0.
-
-                       If the device is not "seekable" (e.g. webcam) try
-                       reading it all at once in full snaps via the "snap:"
-                       mode (note: this is a resource hog).  If you are using
-                       file: or map: AND the device needs to be reopened for
-                       *every* snapfb snapshot, set the environment variable:
-                       SNAPFB_RAWFB_RESET=1 as well.
-
-                       If you want x11vnc to dynamically transform a 24bpp
-                       rawfb to 32bpp (note that this will be slower) also
-                       supply the -24to32 option.  This would be useful for,
-                       say, a video camera that delivers the pixel data as
-                       24bpp packed RGB.  This is the default under "video"
-                       mode if the bpp is 24.
-
-                       Normally the bits per pixel, B, is 8, 16, or 32 (or
-                       rarely 24), however there is also some support for
-                       B < 8 (e.g. old graphics displays 4 bpp or 1 bpp).
-                       In this case you certainly must supply the masks as
-                       well: WxHxB:R/G/B.  The pixels will be padded out to
-                       8 bpp using depth 8 truecolor.  The scheme currently
-                       does not work with snap fb (ask if interested.) B=1
-                       monochrome example: file:/dev/urandom@128x128x1:1/1/1
-                       Some other like this are 128x128x2:3/3/3 128x128x4:7/7/7
-
-                       For B < 8 framebuffers you can also set the env. var
-                       RAWFB_CGA=1 to try a CGA mapping for B=4 (e.g. linux
-                       vga16fb driver.)  Note with low bpp and/or resolution
-                       VGA and VGA16 modes on the Linux console one's attempt
-                       to export them via x11vnc can often be thwarted due to
-                       special color palettes, pixel packings, and even video
-                       painting buffering.  OTOH, often experimenting with the
-                       RGB masks can yield something recognizable.
-
-                       VIDEO4LINUX: on Linux some attempt is made to handle
-                       video devices (webcams or TV tuners) automatically.
-                       The idea is the WxHxB will be extracted from the
-                       device itself.  So if you do not supply "@WxHxB...
-                       parameters x11vnc will try to determine them.  It first
-                       tries the v4l API if that support has been compiled in.
-                       Otherwise it will run the v4l-info(1) external program
-                       if it is available.
-
-                       The simplest examples are "-rawfb video" and "-rawfb
-                       video1" which imply the device file /dev/video and
-                       /dev/video1, respectively.  You can also supply the
-                       /dev if you like, e.g. "-rawfb /dev/video0"
-
-                       Since the video capture device framebuffer usually
-                       changes continuously (e.g. brightness fluctuations),
-                       you may want to use the -wait, -slow_fb, or -defer
-                       options to lower the "framerate" to cut down on
-                       network VNC traffic.
-
-                       A more sophisticated video device scheme allows
-                       initializing the device's settings using:
-
-                           -rawfb video:<settings>
-
-                       The prefix could also be, as above, e.g. "video1:" to
-                       specify the device file.  The v4l API must be available
-                       for this to work.  Otherwise, you will need to try
-                       to initialize the device with an external program,
-                       e.g. xawtv, spcaview, and hope they persist when x11vnc
-                       re-opens the device.
-
-                       <settings> is a comma separated list of key=value pairs.
-                       The device's brightness, color, contrast, and hue can
-                       be set to percentages, e.g. br=80,co=50,cn=44,hu=60.
-
-                       The device filename can be set too if needed (if it
-                       does not start with "video"), e.g. fn=/dev/qcam.
-
-                       The width, height and bpp of the framebuffer can be
-                       set via, e.g., w=160,h=120,bpp=16.
-
-                       Related to the bpp above, the pixel format can be set
-                       via the fmt=XXX, where XXX can be one of: GREY, HI240,
-                       RGB555, RGB565, RGB24, and RGB32 (with bpp 8, 8, 16, 16,
-                       24, and 32 respectively).  See http://www.linuxtv.org
-                       for more info (V4L api).
-
-                       For TV/rf tuner cards one can set the tuning mode
-                       via tun=XXX where XXX can be one of PAL, NTSC, SECAM,
-                       or AUTO.
-
-                       One can switch the input channel by the inp=XXX setting,
-                       where XXX is the name of the input channel (Television,
-                       Composite1, S-Video, etc).  Use the name that is in the
-                       information about the device that is printed at startup.
-
-                       For input channels with tuners (e.g. Television) one
-                       can change which station is selected by the sta=XXX
-                       setting.  XXX is the station number.  Currently only
-                       the ntsc-cable-us (US cable) channels are built into
-                       x11vnc.  See the -freqtab option below to supply one
-                       from xawtv. If XXX is greater than 500, then it is
-                       interpreted as a raw frequency in KHz.
-
-                       Example:
-
-                       -rawfb video:br=80,w=320,h=240,fmt=RGB32,tun=NTSC,sta=47
-
-                       one might need to add inp=Television too for the input
-                       channel to be TV if the card doesn't come up by default
-                       in that one.
-
-                       Note that not all video capture devices will support
-                       all of the above settings.
-
-                       See the -pipeinput VID option below for a way to control
-                       the settings through the VNC Viewer via keystrokes.
-                       As a shortcut, if the string begins "Video.." instead
-                       of "video.." then -pipeinput VID is implied.
-
-                       As above, if you specify a "@WxHxB..." after the
-                       <settings> string they are used verbatim: the device
-                       is not queried for the current values.  Otherwise the
-                       device will be queried.
-
-                       LINUX CONSOLE:  The following describes some ways to
-                       view and possibly interact with the Linux text/graphics
-                       console (i.e. not X11 XFree86/Xorg)
-
-                       Note: If the LibVNCServer LinuxVNC program is on your
-                       system you may want to use that instead of the following
-                       method because it will be faster and more accurate
-                       for the Linux text console and includes mouse support.
-                       There is, however, the basic LinuxVNC functionality in
-                       x11vnc if you replace "console" with "vt" in the
-                       examples below.
-
-                       If the rawfb string begins with "console" the
-                       framebuffer device /dev/fb0 is opened and /dev/tty0 is
-                       opened too.  The latter is used to inject keystrokes
-                       (not all are supported, but the basic ones are).
-                       You will need to be root to inject keystrokes, but
-                       not necessarily to open /dev/fb0.  /dev/tty0 refers to
-                       the active VT, to indicate one explicitly, use, e.g.,
-                       "console2" for /dev/tty2, etc. by indicating the
-                       specific VT number.
-
-                       For the Linux framebuffer device, /dev/fb0, (fb1,
-                       etc) to be enabled the appropriate kernel drivers must
-                       be loaded.  E.g. vesafb or vga16fb and also by setting
-                       the boot parameter vga=0x301 (or 0x314, 0x317, etc.)
-                       (The vga=... method is the preferred way; set your
-                       machines up that way.)  Otherwise there will be a
-                       'No such device' error.  You can also load a Linux
-                       framebuffer driver specific to your make of video card
-                       for more functionality.  Once the machine is booted one
-                       can often 'modprobe' the fb driver as root to obtain
-                       a framebuffer device.
-
-                       If you cannot get /dev/fb0 working on Linux, try
-                       using the LinuxVNC emulation mode by "-rawfb vtN"
-                       where N = 1, ... 6 is the Linux Virtual Terminal (aka
-                       virtual console) you wish to view, e.g. "-rawfb vt2".
-                       Unlike /dev/fb mode, it need not be the active Virtual
-                       Terminal.  Note that this mode can only show text and
-                       not graphics.  x11vnc polls the text in /dev/vcsaN
-
-                       Set the env. var. RAWFB_VCSA_BW=1 to disable colors in
-                       the "vtN" mode (i.e. black and white only.)  If you
-                       do not prefer the default 16bpp set RAWFB_VCSA_BPP to
-                       8 or 32.  If you need to tweak the rawfb parameters by
-                       using the 'console_guess' string printed at startup,
-                       be sure to indicate the snap: method.
-
-                       uinput: If the Linux version appears to be 2.6
-                       or later and the "uinput" module appears to be
-                       present (modprobe uinput), then the uinput method
-                       will be used instead of /dev/ttyN.  uinput allows
-                       insertion of BOTH keystrokes and mouse input and so it
-                       preferred when accessing graphical (e.g. QT-embedded)
-                       linux console apps.  It also provides more accurate
-                       keystroke insertion.  See -pipeinput UINPUT below for
-                       more information on this mode; you will have to use
-                       -pipeinput if you want to tweak any UINPUT parameters.
-                       You may also want to also use the -nodragging and
-                       -cursor none options.  Use "console0", etc  or
-                       -pipeinput CONSOLE to force the /dev/ttyN method.
-
-                       Note you can change the Linux VT remotely using the
-                       chvt(1) command to make the one you want be the active
-                       one (e.g. 'chvt 3').  Sometimes switching out and back
-                       corrects the framebuffer's graphics state.  For the
-                       "-rawfb vtN" mode there is no need to switch the VT's.
-
-                       To skip input injecting entirely use "consolex"
-                       or "vtx".
-
-                       The string "/dev/fb0" (1, etc.) can be used instead
-                       of "console".  This can be used to specify a different
-                       framebuffer device, e.g. /dev/fb1.  As a shortcut the
-                       "/dev/" can be dropped.  If the name is something
-                       nonstandard, use "console:/dev/foofb"
-
-                       If you do not want x11vnc to guess the framebuffer's
-                       WxHxB and masks automatically (sometimes the kernel
-                       gives incorrect information), specify them with a @WxHxB
-                       (and optional :R/G/B masks) at the end of the string.
-
-                       Examples:
-                           -rawfb console
-                           -rawfb /dev/fb0           (same)
-                           -rawfb console3           (force /dev/tty3)
-                           -rawfb consolex           (no keystrokes or mouse)
-                           -rawfb console:/dev/nonstd
-                           -rawfb console -pipeinput UINPUT:accel=4.0
-                           -rawfb vt3                (/dev/tty3 w/o /dev/fb0)
-
-                       VNC HOST: if the -rawfb string is of the form
-                       "vnc:host:N" then the VNC display "N" on the remote
-                       VNC server "host" is connected to (i.e. x11vnc acts as
-                       a VNC client itself) and that framebuffer is exported.
-
-                       This mode is really only of use if you are trying
-                       to improve performance in the case of many (e.g. >
-                       10) simultaneous VNC viewers, and you try a divide
-                       and conquer scheme to reduce bandwidth and improve
-                       responsiveness.  (However, another user found this mode
-                       useful to export a demo display through a slow link:
-                       then multiple demo viewers connected to the reflecting
-                       x11vnc on the fast side of the link, and so avoided
-                       all of the demo viewers going through the slow link.)
-
-                       For example, if there will be 64 simultaneous VNC
-                       viewers this can lead to a lot of redundant VNC traffic
-                       to and from the server host:N, extra CPU usage,
-                       and all viewers response can be reduced by having
-                       to wait for writes to the slowest client to finish.
-                       However, if you set up 8 reflectors/repeaters started
-                       with option -rawfb vnc:host:N, then there are only
-                       8 connections to host:N.  Each repeater then handles
-                       8 vnc viewer connections thereby spreading the load
-                       around.  In classroom broadcast usage, try to put the
-                       repeaters on different switches.  This mode is the same
-                       as -reflect host:N.  Replace "host:N" by "listen"
-                       or "listen:port" for a reverse connection.
-
-                       Overall performance will not be as good as a single
-                       direct connection because, among other things,
-                       there is an additional level of framebuffer polling
-                       and pointer motion can still induce many changes per
-                       second that must be propagated.  Tip: if the remote VNC
-                       is x11vnc doing wireframing, or an X display that does
-                       wireframing that gives much better response than opaque
-                       window dragging.  Consider the -nodragging option if
-                       the problem is severe.
-
-                       The env. var. X11VNC_REFLECT_PASSWORD can be set to
-                       the password needed to log into the vnc host server, or
-                       to "file:path_to_file" to indicate a file containing
-                       the password as its first line.
-
-                       To set the pixel format that x11vnc requests as a VNC
-                       CLIENT set the env. vars: X11VNC_REFLECT_bitsPerSample
-                       X11VNC_REFLECT_samplesPerPixel, and
-                       X11VNC_REFLECT_bytesPerPixel; the defaults are 8, 3, 4.
-                       2, 3, 1 would give a low color mode.  See the function
-                       rfbGetClient() in libvncclient for more info.
-
-                       The VNC HOST mode implies -shared.  Use -noshared as
-                       a subsequent cmdline option to disable sharing.
-
--freqtab file          For use with "-rawfb video" for TV tuner devices to
-                       specify station frequencies.  Instead of using the built
-                       in ntsc-cable-us mapping of station number to frequency,
-                       use the data in file.  For stations that are not
-                       numeric, e.g. SE20, they are placed above the highest
-                       numbered station in the order they are found.  Example:
-                       "-freqtab /usr/X11R6/share/xawtv/europe-west.list"
-                       You can make your own freqtab by copying the xawtv
-                       format.
-
--pipeinput cmd         This option lets you supply an external command in
-                       "cmd" that x11vnc will pipe all of the user input
-                       events to in a simple format.  In -pipeinput mode by
-                       default x11vnc will not process any of the user input
-                       events.  If you prefix "cmd" with "tee:" it will
-                       both send them to the pipe command and process them.
-                       For a description of the format run "-pipeinput
-                       tee:/bin/cat".  Another prefix is "reopen" which
-                       means to reopen pipe if it exits.  Separate multiple
-                       prefixes with commas.
-
-                       In combination with -rawfb one might be able to
-                       do amusing things (e.g. control non-X devices).
-                       To facilitate this, if -rawfb is in effect then the
-                       value is stored in X11VNC_RAWFB_STR for the pipe command
-                       to use if it wants. Do 'env | grep X11VNC' for more.
-
-                       Built-in pipeinput modes (no external program required):
-
-                       If cmd is "VID" and you are using the -rawfb for a
-                       video capture device, then an internal list of keyboard
-                       mappings is used to set parameters of the video.
-                       The mappings are:
-
-                         "B" and "b" adjust the brightness up and down.
-                         "H" and "h" adjust the hue.
-                         "C" and "c" adjust the colour.
-                         "N" and "n" adjust the contrast.
-                         "S" and "s" adjust the size of the capture screen.
-                         "I" and "i" cycle through input channels.
-                         Up and Down arrows adjust the station (if a tuner)
-                         F1, F2, ..., F6 will switch the video capture pixel
-                         format to HI240, RGB565, RGB24, RGB32, RGB555, and
-                         GREY respectively.  See -rawfb video for details.
-
-                       If cmd is "CONSOLE" or "CONSOLEn" where n
-                       is a Linux console number, then the linux console
-                       keystroke insertion to /dev/ttyN (see -rawfb console)
-                       is performed.
-
-                       If cmd begins with "UINPUT" then the Linux uinput
-                       module is used to insert both keystroke and mouse events
-                       to the Linux console (see -rawfb above).  This usually
-                       is the /dev/input/uinput device file (you may need to
-                       create it with "mknod /dev/input/uinput c 10 223"
-                       and insert the module with "modprobe uinput".
-
-                       The UINPUT mode currently only does US keyboards (a
-                       scan code option may be added), and not all keysyms
-                       are supported.  But it is probably more accurate than
-                       the "CONSOLE" method.
-
-                       You may want to use the options -cursor none and
-                       -nodragging in this mode.
-
-                       Additional tuning options may be supplied via:
-                       UINPUT:opt1,opt2,... (a comma separated list). If an
-                       option begins with "/" it is taken as the uinput
-                       device file.
-
-                       Which uinput is injected can be controlled by an option
-                       string made of the characters "K", "M", and "B"
-                       (see the -input option), e.g. "KM" allows keystroke
-                       and motion but not button clicks.
-
-                       A UINPUT option of the form: accel=f, or accel=fx+fy
-                       sets the mouse motion "acceleration".  This is used
-                       to correct raw mouse relative motion into how much the
-                       application cursor moves (x11vnc has no control over,
-                       or knowledge of how the windowing application interprets
-                       the raw mouse motions).  Typically the acceleration
-                       for an X display is 2 (see xset "m" option).  "f"
-                       is a floating point number, e.g. 3.0.  Use "fx+fy"
-                       if you need to supply different corrections for x and y.
-
-                       Note: the default acceleration is 2.0 since it seems
-                       both X and qt-embedded often (but not always) use
-                       this value.
-
-                       Even with a correct accel setting the mouse position
-                       will get out of sync (probably due to a mouse
-                       "threshold" setting where the acceleration doe not
-                       apply, set xset(1)).  The option reset=N sets the
-                       number of ms (default 150) after which the cursor is
-                       attempted to be reset (by forcing the mouse to (0,
-                       0) via small increments and then back out to (x, y)
-                       in 1 jump), This correction seems to be needed but can
-                       cause jerkiness or unexpected behavior with menus, etc.
-                       Use reset=0 to disable.
-
-                       If you set the env. var X11VNC_UINPUT_THRESHOLDS then
-                       the thresh=n mode will be enabled.  It is currently
-                       not working well.  If |dx| <= thresh and |dy| < thresh
-                       no acceleration is applied.  Use "thresh=+n" |dx| +
-                       |dy| < thresh to be used instead (X11?)
-
-                       Example:
-                           -pipeinput UINPUT:accel=4.0 -cursor none
-
-                       If the uinput device has an absolute pointer (as opposed
-                       to a normal mouse that is a relative pointer) you can
-                       specify the option "abs".  Note that a touchpad
-                       on a laptop is an absolute device to some degree.
-                       This (usually) avoids all the problems with mouse
-                       acceleration.  If x11vnc has trouble deducing the
-                       size of the device, use "abs=WxH".  Furthermore,
-                       if the device is a touchscreen (assumed to have an
-                       absolute pointer) use "touch" or "touch=WxH".
-                       For touchscreens, when a mouse button is pressed,
-                       a pressure increase is injected, and when the button
-                       is released a pressure of zero is injected.
-
-                       If touch has been set, use "touch_always=1" to
-                       indicate whenever the mouse moves with no button
-                       pressed, a touch event of zero pressure should be
-                       sent anyway.  Also use "btn_touch=1" to indicate a
-                       BTN_TOUCH keystroke press or release should be sent
-                       instead of a pressure change.  Set "dragskip=n" to
-                       skip n dragged mouse touches (with pressure applied)
-                       before injecting one.  To indicate the pressure that
-                       should be sent when there is a button click for a
-                       touchscreen device, specify pressure=n, e.g. n=5. The
-                       default is n=1.

-                       If a touch screen is being used ("touch" above)
-                       and it is having its input processed by tslib, you can
-                       specify the tslib calibration file via tslib_cal=<file>.
-                       For example, tslib_cal=/etc/pointercal.  To get accurate
-                       or even usable positioning this is required when tslib
-                       is in use.
-
-                       The Linux uinput mechanism can be bypassed and one can
-                       write input events DIRECTLY to the devices instead.
-                       To do this, specify one or more of the following
-                       for the input classes: direct_rel=<device>
-                       direct_abs=<device> direct_btn=<device> or
-                       direct_key=<device>.  The <device> file is usually
-                       something like /dev/input/event1 but you can specify
-                       any device file or pipe.  You must specify each one
-                       of the above classes even if they correspond to the
-                       same device file (rel/abs and btn are often the same.)
-                       Look at the file /proc/bus/input/devices to get an idea
-                       what is available and the device filenames.  Note:
-                       The /dev/input/mouse* devices do not seem to work,
-                       use the corresponding /dev/input/event* file instead.
-                       Any input class not directly specified as above will be
-                       handled via the uinput mechanism.  To disable creating a
-                       uinput device (and thereby discarding unhandled input),
-                       specify "nouinput".
-
-                       Examples:
-
-                         -pipeinput UINPUT:direct_abs=/dev/input/event1
-
-                       this was used on a qtmoko Neo freerunner (armel):
-
-                         -pipeinput UINPUT:touch,tslib_cal=/etc/pointercal,
-                          direct_abs=/dev/input/event1,nouinput,dragskip=4
-
-                       (where the long line has been split into two.)
-
-                       You can set the env. var X11VNC_UINPUT_DEBUG=1 or higher
-                       to get debugging output for UINPUT mode.

-                       caching mode, try to cache pull down menus (not perfect
-                       because they have animated fades, etc.)

--macnorawfb            For the native MacOSX server, disable the raw memory
-                       address screen capture method.
-
-                       MACOSX NOTE: There are some deprecated MacOSX interfaces
-                       to inject keyboard and mouse events and the raw memory
-                       access method is deprecated as well (however, OpenGL
-                       will be preferred if available because it is faster.)
-                       One can force not using any deprecated interfaces at
-                       compile time by setting -DX11VNC_MACOSX_NO_DEPRECATED=1
-                       in CPPFLAGS.  Or to turn them off one by one:
-                       -DX11VNC_MACOSX_NO_DEPRECATED_LOCALEVENTS=1,
-                       -DX11VNC_MACOSX_NO_DEPRECATED_POSTEVENTS=1 or
-                       -DX11VNC_MACOSX_NO_DEPRECATED_FRAMEBUFFER=1
-                       At run time, for testing and workarounds, one can
-                       disable them by using:
-                       -env X11VNC_MACOSX_NO_DEPRECATED=1
-                       -env X11VNC_MACOSX_NO_DEPRECATED_LOCALEVENTS=1
-                       -env X11VNC_MACOSX_NO_DEPRECATED_POSTEVENTS=1 or
-                       -env X11VNC_MACOSX_NO_DEPRECATED_FRAMEBUFFER=1
-                       Note: When doing either of these for the mouse input
-                       not everything works currently, e.g. double clicks and
-                       wireframing.  Also, screen resolution and pixel depth
-                       changes will not be automatically detected unless the
-                       deprecated framebuffer interfaces are allowed.
-
-                       Conversely, if you are compiling on an
-                       older machine that does not have some of
-                       the newer interfaces, you may need to specify
-                       -DX11VNC_MACOSX_NO_CGEVENTCREATESCROLLWHEELEVENT
-                       -DX11VNC_MACOSX_NO_CGEVENTCREATEMOUSEEVENT or
-                       -DX11VNC_MACOSX_NO_CGEVENTCREATEKEYBOARDEVENT.  Use
-                       -DX11VNC_MACOSX_USE_GETMAINDEVICE to regain the very
-                       old QuickDraw GetMainDevice() interface (rare...)
-
--gui [gui-opts]        Start up a simple tcl/tk gui based on the remote
-                       control options -remote/-query described below.
-                       Requires the "wish" program to be installed on the
-                       machine.  "gui-opts" is not required: the default
-                       is to start up both the full gui and x11vnc with the
-                       gui showing up on the X display in the environment
-                       variable DISPLAY.
-
-                       "gui-opts" can be a comma separated list of items.
-                       Currently there are these types of items: 1) a gui
-                       mode, a 2) gui "simplicity", 3) the X display the
-                       gui should display on, 4) a "tray" or "icon" mode,
-                       and 5) a gui geometry.
-
-                       1) The gui mode can be "start", "conn", or "wait"
-                       "start" is the default mode above and is not required.
-                       "conn" means do not automatically start up x11vnc,
-                       but instead just try to connect to an existing x11vnc
-                       process.  "wait" means just start the gui and nothing
-                       else (you will later instruct the gui to start x11vnc
-                       or connect to an existing one.)
-
-                       2) The gui simplicity is off by default (a power-user
-                       gui with all options is presented) To start with
-                       something less daunting supply the string "simple"
-                       ("ez" is an alias for this).  Once the gui is
-                       started you can toggle between the two with "Misc ->
-                       simple_gui".
-
-                       3) Note the possible confusion regarding the potentially
-                       two different X displays: x11vnc polls one, but you
-                       may want the gui to appear on another.  For example, if
-                       you ssh in and x11vnc is not running yet you may want
-                       the gui to come back to you via your ssh redirected X
-                       display (e.g. localhost:10).
-
-                       If you do not specify a gui X display in "gui-opts"
-                       then the DISPLAY environment variable and -display
-                       option are tried (in that order).  Regarding the x11vnc
-                       X display the gui will try to communication with, it
-                       first tries -display and then DISPLAY.  For example,
-                       "x11vnc -display :0 -gui otherhost:0", will remote
-                       control an x11vnc polling :0 and display the gui on
-                       otherhost:0 The "tray/icon" mode below reverses this
-                       preference, preferring to display on the x11vnc display.
-
-                       4) When "tray" or "icon" is specified, the gui
-                       presents itself as a small icon with behavior typical
-                       of a "system tray" or "dock applet".  The color
-                       of the icon indicates status (connected clients) and
-                       there is also a balloon status.  Clicking on the icon
-                       gives a menu from which properties, etc, can be set and
-                       the full gui is available under "Advanced".  To be
-                       fully functional, the gui mode should be "start"
-                       (the default).
-
-                       Note that tray or icon mode will imply the -forever
-                       x11vnc option (if the x11vnc server is started along
-                       with the gui) unless -connect or -connect_or_exit has
-                       been specified.  So x11vnc (and the tray/icon gui)
-                       will wait for more connections after the first client
-                       disconnects.  If you want only one viewer connection
-                       include the -once option.
-
-                       For "icon" the gui just a small standalone window.
-                       For "tray" it will attempt to embed itself in the
-                       "system tray" if possible. If "=setpass" is appended the
-n
-                       at startup the X11 user will be prompted to set the
-                       VNC session password.  If =<hexnumber> is appended
-                       that icon will attempt to embed itself in the window
-                       given by hexnumber.  Use =noadvanced to disable the
-                       full gui. (To supply more than one, use "+" sign).
-                       E.g. -gui tray=setpass and -gui icon=0x3600028
-
-                       Other modes: "full", the default and need not be
-                       specified.  "-gui none", do not show a gui, useful
-                       to override a ~/.x11vncrc setting, etc.
-
-                       5) When "geom=+X+Y" is specified, that geometry
-                       is passed to the gui toplevel.  This is the icon in
-                       icon/tray mode, or the full gui otherwise.  You can
-                       also specify width and height, i.e. WxH+X+Y, but it
-                       is not recommended.  In "tray" mode the geometry is
-                       ignored unless the system tray manager does not seem
-                       to be running.  One could imagine using something like
-                       "-gui tray,geom=+4000+4000" with a display manager
-                       to keep the gui invisible until someone logs in...
-
-                       More icon tricks, "icon=minimal" gives an icon just
-                       with the VNC display number.  You can also set the font
-                       with "iconfont=...".  The following could be useful:
-                       "-gui icon=minimal,iconfont=5x8,geom=24x10+0-0"
-
-                       General examples of the -gui option: "x11vnc -gui",
-                       "x11vnc -gui ez" "x11vnc -gui localhost:10",
-                       "x11vnc -gui conn,host:0", "x11vnc -gui tray,ez"
-                       "x11vnc -gui tray=setpass"
-
-                       If you do not intend to start x11vnc from the gui
-                       (i.e. just remote control an existing one), then the
-                       gui process can run on a different machine from the
-                       x11vnc server as long as X permissions, etc. permit
-                       communication between the two.
-
-                       FONTS: On some systems the tk fonts can be too small,
-                       jagged, or otherwise unreadable.  There are 4 env vars
-                       you can set to be the tk font you prefer:
-
-                       X11VNC_FONT_BOLD   main font for menus and buttons.
-                       X11VNC_FONT_FIXED  font for fixed width text.
-
-                       X11VNC_FONT_BOLD_SMALL  tray icon font.
-                       X11VNC_FONT_REG_SMALL   tray icon menu font.
-
-                       The last two only apply for the tray icon mode.
-
-                       Here are some examples:
-
-                       -env X11VNC_FONT_BOLD='Helvetica -16 bold'
-                       -env X11VNC_FONT_FIXED='Courier -14'
-                       -env X11VNC_FONT_REG_SMALL='Helvetica -12'
-
-                       You can put the lines like the above (without the
-                       quotes) in your ~/.x11vncrc file to avoid having to
-                       specify them on the x11vnc command line.
-
--remote command        Remotely control some aspects of an already running
-                       x11vnc server.  "-R" and "-r" are aliases for
-                       "-remote".  After the remote control command is
-                       sent to the running server the 'x11vnc -remote ...'
-                       x11vnc command exits.  You can often use the -query
-                       command (see below) to see if the x11vnc server
-                       processed your -remote command.
-
-                       The default communication channel is that of X
-                       properties (specifically X11VNC_REMOTE), and so this
-                       command must be run with correct settings for DISPLAY
-                       and possibly XAUTHORITY to connect to the X server
-                       and set the property.  Alternatively, use the -display
-                       and -auth options to set them to the correct values.
-                       The running server cannot use the -novncconnect option
-                       because that disables the communication channel.
-                       See below for alternate channels.
-
-                       For example: 'x11vnc -remote stop' (which is the same as
-                       'x11vnc -R stop') will close down the x11vnc server.
-                       'x11vnc -R shared' will enable shared connections, and
-                       'x11vnc -R scale:3/4' will rescale the desktop.
-
-                       To use a different name for the X11 property (e.g. to

-                       bcx_xattach:str  This remote control command is for
-                       use with the BARCO xattach program or the x2x program.
-                       Both of these programs are for 'pointer and keyboard'
-                       sharing between separate X displays.  In general the
-                       two displays are usually nearby, e.g. on the same desk,
-                       and this allows the user to share a single pointer and
-                       keyboard between them.  The user moves the mouse to
-                       an edge and then the mouse pointer appears to 'jump'
-                       to the other display screen.  Thus it emulates what a
-                       single X server would do for two screens (e.g. :0.0 and
-                       :0.1) The illusion of a single Xserver with multiple
-                       screens is achieved by forwarding events to the 2nd
-                       one via the XTEST extension.
-
-                       What the x11vnc bcx_xattach command does is to perform
-                       some pointer movements to try to INDUCE xattach/x2x
-                       to 'jump' to the other display.  In what follows the
-                       'master' display refers to the one that when it has
-                       'focus' it is basically doing nothing besides watching
-                       for the mouse to go over an edge.  The 'slave'
-                       display refers to the one to which the mouse and
-                       keyboard is redirected to once an edge in the master
-                       has been crossed.  Note that the x11vnc executing the
-                       bcx_xattach command MUST be the one connected to the
-                       *master* display.
-
-                       Also note that when input is being redirected (via
-                       XTEST) from the master display to the slave display,
-                       the master display's pointer and keyboard are *grabbed*
-                       by xattach/x2x.  x11vnc can use this info to verify that
-                       the master/slave mode change has taken place correctly.
-                       If you specify the "ifneeded" option (see below)
-                       and the initial grab state is that of the desired
-                       final state, then no pointer movements are injected
-                       and "DONE,GRAB_OK" is returned.
-
-                       "str" must contain one of "up", "down", "left",
-                       or "right" to indicate the direction of the 'jump'.
-                       "str" must also contain one of "master_to_slave"
-                       or "slave_to_master" to indicate the type of mode
-                       change induced by the jump.  Use "M2S" and "S2M"
-                       as shorter aliases.
-
-                       "str" may be a "+" separated list of additional
-                       tuning options.  The "shift=n" option indicates an
-                       offset shift position away from (0,0) (default 20).
-                       "final=x+y" specifies the final position of the cursor
-                       at the end of the normal move sequence; default 30+30.
-                       "extra_move=x+y" means to do one more pointer move
-                       after "final" to x+y.  "dt=n" sets the sleep time
-                       in milliseconds between pointer moves (default: 40ms)
-                       "retry=n" specifies the maximum number of retries if
-                       the grab state change fails. "ifneeded" means to not
-                       apply the pointer movements if the initial grab state is
-                       that of the desired final state. "nograbcheck" means
-                       to not check if the grab state changed as expected and
-                       only apply the pointer movements (default is to check
-                       the grab states.)
-
-                       If you do not specify "up", etc., to bcx_xattach
-                       nothing will be attempted and the command returns
-                       the string FAIL,NO_DIRECTION_SPECIFIED.  If you do
-                       not specify "master_to_slave" or "M2S", etc., to
-                       bcx_xattach nothing will be attempted and the command
-                       returns the string FAIL,NO_MODE_CHANGE_SPECIFIED.
-
-                       Otherwise, the returned string will contain "DONE".
-                       It will be "DONE,GRAB_OK" if the grab state changed
-                       as expected (or if "ifneeded" was supplied and
-                       the initial grab state was already the desired
-                       one.)  If the initial grab state was incorrect,
-                       but the final grab state was correct then it is
-                       "DONE,GRAB_FAIL_INIT".  If the initial grab state
-                       was correct, but the final grab state was incorrect
-                       then it is "DONE,GRAB_FAIL_FINAL".  If both are
-                       incorrect it will be "DONE,GRAB_FAIL".  Under grab
-                       failure the string will be followed by ":p1,k1-p2,k2"
-                       where  p1,k1 indicates the initial pointer and keyboard
-                       grab states and p2,k2 the final ones. If GRAB_FAIL or
-                       GRAB_FAIL_FINAL occurs, the action will be retried up
-                       to 3 times; trying to reset the state and sleeping a
-                       bit between each try.  Set retry=n to adjust the number
-                       of retries, zero to disable retries.
-
-                       Examples:
-                           -R bcx_xattach:down+M2S
-                           -R bcx_xattach:up+S2M
-                           -R bcx_xattach:up+S2M+nograbcheck+dt=30
-                           -R bcx_xattach:down+M2S+extra_move=100+100
-
-                       or use -Q instead of -R to retrieve the result text.

-                       The vncconnect(1) command from standard VNC
-                       distributions may also be used if string is prefixed
-                       with "cmd=" E.g. 'vncconnect cmd=stop'.  Under some
-                       circumstances xprop(1) can used if it supports -set
-                       (see the FAQ).
-
-                       If "-connect /path/to/file" has been supplied to the
-                       running x11vnc server then that file can be used as a
-                       communication channel (this is the only way to remote
-                       control one of many x11vnc's polling the same X display)
-                       Simply run: 'x11vnc -connect /path/to/file -remote ...'
-                       or you can directly write to the file via something
-                       like: "echo cmd=stop > /path/to/file", etc.
-
--query variable        Like -remote, except just query the value of
-                       "variable".  "-Q" is an alias for "-query".
-                       Multiple queries can be done by separating variables
-                       by commas, e.g. -query var1,var2. The results come
-                       back in the form ans=var1:value1,ans=var2:value2,...
-                       to the standard output.  If a variable is read-only,
-                       it comes back with prefix "aro=" instead of "ans=".
-
-                       Some -remote commands are pure actions that do not make
-                       sense as variables, e.g. "stop" or "disconnect", in
-                       these cases the value returned is "N/A".  To direct a
-                       query straight to the X11VNC_REMOTE property or connect
-                       file use "qry=..." instead of "cmd=..."

--QD variable           Just like -query variable, but returns the default
-                       value for that parameter (no running x11vnc server
-                       is consulted)
-
--sync                  By default -remote commands are run asynchronously, that
-                       is, the request is posted and the program immediately
-                       exits.  Use -sync to have the program wait for an
-                       acknowledgement from the x11vnc server that command was
-                       processed (somehow).  On the other hand -query requests
-                       are always processed synchronously because they have
-                       to wait for the answer.
-
-                       Also note that if both -remote and -query requests are
-                       supplied on the command line, the -remote is processed
-                       first (synchronously: no need for -sync), and then
-                       the -query request is processed in the normal way.
-                       This allows for a reliable way to see if the -remote
-                       command was processed by querying for any new settings.
-                       Note however that there is timeout of a few seconds
-                       (see the next paragraph) so if the x11vnc takes longer
-                       than that to process the requests the requester will
-                       think that a failure has taken place.
-
-                       The default is to wait 3.5 seconds.  Or if cmd=stop
-                       only 1.0 seconds.  If cmd matches 'script:' then it
-                       will wait up to 10.0 seconds.  Set X11VNC_SYNC_TIMEOUT
-                       to the number of seconds you want it to wait.
-
--query_retries str     If a query fails to get a response from an x11vnc
-                       server, retry up to n times.  "str" is specified as
-                       n[:t][/match]  Optionally the delay between tries may
-                       be specified by "t" a floating point time (default
-                       0.5 seconds.)  Note: the response is not checked for
-                       validity or whether it corresponds to the query sent.
-                       The query "ping:mystring" may be used to help uniquely
-                       identify the query.  Optionally, a matching string after
-                       a "/" will be used to check the result text.  Up to
-                       n retries will take place until the matching string is
-                       found in the output text.  If the match string is never
-                       found the program's exit code is 1; if the match is
-                       found it exits with 0.  Note that there may be stdout
-                       printed for each retry (i.e. multiple lines printed
-                       out to stdout.)
-                       Example: -query_retries 4:1.5/grab_state
-
--remote_prefix str     Enable a remote-control communication channel for
-                       connected VNC clients.  str is a non-empty string. If a
-                       VNC client sends rfbCutText having the prefix "str"
-                       then the part after it is processed as though it were
-                       sent via 'x11vnc -remote ...'.  If it begins with
-                       neither 'cmd=' nor 'qry=' then 'qry=' is assumed.
-                       Any corresponding output text for that remote control
-                       command is sent back to all client as rfbCutText.
-                       The returned output is also prefixed with "str".
-                       Example: -remote_prefix DO_THIS:
-
-                       Note that enabling -remote_prefix allows the remote
-                       VNC viewers to run x11vnc -remote commands.  Do not
-                       use this option if they are not to be trusted.
-
--noremote              Do not process any remote control commands or queries.
--yesremote             Do process remote control commands or queries.
-                       Default: -yesremote
-
-                       A note about security wrt remote control commands.
-                       If someone can connect to the X display and change
-                       the property X11VNC_REMOTE, then they can remotely
-                       control x11vnc.  Normally access to the X display is
-                       protected.  Note that if they can modify X11VNC_REMOTE
-                       on the X server, they have enough permissions to also
-                       run their own x11vnc and thus have complete control
-                       of the desktop.  If the  "-connect /path/to/file"
-                       channel is being used, obviously anyone who can write
-                       to /path/to/file can remotely control x11vnc.  So be
-                       sure to protect the X display and that file's write
-                       permissions.  See -privremote below.
-
-                       If you are paranoid and do not think -noremote is
-                       enough, to disable the X11VNC_REMOTE property channel
-                       completely use -novncconnect, or use the -safer option
-                       that shuts many things off.
-
--unsafe                A few remote commands are disabled by default
-                       (currently: id:pick, accept:<cmd>, gone:<cmd>, and
-                       rawfb:setup:<cmd>) because they are associated with
-                       running external programs.  If you specify -unsafe, then
-                       these remote-control commands are allowed.  Note that
-                       you can still specify these parameters on the command
-                       line, they just cannot be invoked via remote-control.
--safer                 Equivalent to: -novncconnect -noremote and prohibiting
-                       -gui and the -connect file. Shuts off communcation
-                       channels.
--privremote            Perform some sanity checks and disable remote-control
-                       commands if it appears that the X DISPLAY and/or
-                       connectfile can be accessed by other users.  Once
-                       remote-control is disabled it cannot be turned back on.
--nocmds                No external commands (e.g. system(3), popen(3), exec(3))
-                       will be run at all.
--allowedcmds list      "list" contains a comma separated list of the only
-                       external commands that can be run.  The full list of
-                       associated options is:
-
-                        stunnel, ssl, unixpw, WAIT, zeroconf, id, accept,
-                        afteraccept, gone, pipeinput, v4l-info, rawfb-setup,
-                        dt, gui, ssh, storepasswd, passwdfile, custom_passwd,
-                        findauth, crash.
-
-                       See each option's help to learn the associated external
-                       command.  Note that the -nocmds option takes precedence
-                       and disables all external commands.
-
--deny_all              For use with -remote nodeny: start out denying all
-                       incoming clients until "-remote nodeny" is used to
-                       let them in.
-
-
-
-These options are passed to LibVNCServer:
-
--rfbport port          TCP port for RFB protocol
--rfbwait time          max time in ms to wait for RFB client
--rfbauth passwd-file   use authentication on RFB protocol
-                       (use 'storepasswd' to create a password file)
--rfbversion 3.x        Set the version of the RFB we choose to advertise
--permitfiletransfer    permit file transfer support
--passwd plain-password use authentication
-                       (use plain-password as password, USE AT YOUR RISK)
--deferupdate time      time in ms to defer updates (default 40)
--deferptrupdate time   time in ms to defer pointer updates (default none)
--desktop name          VNC desktop name (default "LibVNCServer")
--alwaysshared          always treat new clients as shared
--nevershared           never treat new clients as shared
--dontdisconnect        don't disconnect existing clients when a new non-shared
-                       connection comes in (refuse new connection instead)
--httpdir dir-path      enable http server using dir-path home
--httpport portnum      use portnum for http connection
--enablehttpproxy       enable http proxy support
--progressive height    enable progressive updating for slow links
--listen ipaddr         listen for connections only on network interface with
-                       addr ipaddr. '-listen localhost' and hostname work too.
-
-libvncserver-tight-extension options:
--disablefiletransfer   disable file transfer
--ftproot string        set ftp root
-
-   Pretty wild huh? Contact me if you have any questions or problems.

-x11vnc 0.9.13	2010-12-20
-
-New in the 0.9.13 x11vnc release:
-
-	Improved support for non-X11 touchscreen devices (e.g. handheld or
-		cell phone) via Linux uinput input injection.  Additional
-		tuning parameters are added. TSLIB touchscreen calibration
-		is supported. Tested on Qtmoko Neo Freerunner.
-
-		A tool, misc/uinput.pl, is provided to diagnose uinput
-		behavior on new devices.
-
-		The env. vars. X11VNC_UINPUT_BUS and X11VNC_UINPUT_VERSION
-		are available if leaving them unset does not work.
-
-	The Linux uinput non-X11 input injection can now be bypassed:
-		events can be directly written to the /dev/input/event
-		devices specified by the user (direct_abs=..., etc.)
-
-		A -pipeinput input injection helper script,
-		misc/qt_tslib_inject.pl is provided as a tweakable
-		non-builtin direct input injection method.
-
-	The list of new uinput parameters for the above two features is:
-		pressure, tslib_cal, touch_always, dragskip, btn_touch;
-		direct_rel, direct_abs, direct_btn, direct_key.
-
-	The included SSL enabled Java VNC Viewers now handle Mouse
-		Wheel events.
-
-
-  miscellaneous new features and changes:
-
-	In -reflect mode, the libvncclient connection can now have
-		the pixel format modified via the environment
-		variables X11VNC_REFLECT_bitsPerSample,
-		X11VNC_REFLECT_samplesPerPixel, and
-		X11VNC_REFLECT_bytesPerPixel
-
-	In -create mode the following environment variables are added
-		to fine tune the behavior: FIND_DISPLAY_NO_LSOF:
-		do not use lsof(1) to try to determine the Linux VT,
-		FIND_DISPLAY_NO_VT_FIND: do not try to determine the
-		Linux VT at all, X11VNC_CREATE_LC_ALL_C_OK: do not bother
-		undoing the setting LC_ALL=C that the create_display
-		script sets.  The performance of the -create script
-		has been improved for large installations (100's of
-		user sessions on one machine.)
-
-	In -unixpw mode, one can now Tab from login: to Password.
-
-	An environment variable, X11VNC_SB_FACTOR, allows one to scale
-		the -sb screenblank sleep time from the default 2 secs.
-
-	In -rawfb mode, a bug is fixed in setting the number of bits
-		per pixel.
-
-	Documented that -grabkbd is no longer working with some/most
-		window managers (it can prevent resizing and menu posting.)
-
-	The macosx deprecated interface GetMainDevice() call is removed.
-		Compile with -DX11VNC_MACOSX_USE_GETMAINDEVICE if needed
-		for an old macosx version...
-
-	Miscellaneous code cleanup.
-
------------------------------------------------------------------------------
-
-
-x11vnc 0.9.12	2010-09-10
-
-New in the 0.9.12 x11vnc release:
-
-	One can now specify the maximum number of displays
-		that can be created in -create mode via the
-		env. var. X11VNC_CREATE_MAX_DISPLAYS
-
-	The X11VNC_NO_LIMIT_SHM env. var. is added to skip any
-		automatic shared memory reduction.
-
-	The kdm display manager is now detected when trying not to get
-		killed by the display manager.
-
-  miscellaneous new features and changes:
-
-	A compile error is fixed when using --with-system-libvncserver
-		pointing to LibVNCServer 0.9.7.
-
-	-nevershared -forever usage mode is documented.
-
-	Old SuSE broken thread local storage is documented.
-
-	x11vnc exit cases are documented.
-
-	A compile bug from forced use of Xdefs.h is worked around.
-
-
------------------------------------------------------------------------------
-
-
-x11vnc 0.9.11	2010-08-08
-
-New in the 0.9.11 x11vnc release:
-
-	The source tree is synchronized with the most recent libvncclient
-		(this only affects -reflect mode.)  The build is fixed
-		for incompatibilities when using an external LibVNCServer
-		(e.g.  ./configure --with-system-libvncserver...)
-
-	The SSL enabled Java VNC Viewer Makefile has been modified so
-		that the jar files that are built are compatible back
-		to Java 1.4.
-
-	In -reflect mode cursor position updates are now handled
-		correctly.
-
-	In -create/-unixpw mode, the env. var. FD_USERPREFS may be set
-		to a filename in the user's home directory that includes
-		default username:options values (so the options do not
-		need to be typed every time at the login prompt.)
-
-  miscellaneous new features and changes:
-
-	An option -always_inject is provided: Even if there is no
-		displacement (dx = dy = 0) for a VNC mouse event force
-		the pointer to the indicated x,y position anyway.
-
-	New java viewer debugging and workaround applet parameters:
-		debugKeyboard mapF5_to_atsign forbid_Ctrl_Alt 
-
-	You can set X11VNC_AVAHI_NAME, X11VNC_AVAHI_HOST, and/or
-		X11VNC_AVAHI_PORT environment variables to override the
-		default values. For example: -env X11VNC_AVAHI_NAME=wally
-
-	When opening the X11 display extra XAUTHLOCALHOSTNAME settings
-		are attempted.
-
-
------------------------------------------------------------------------------
-
-
-x11vnc 0.9.10	2010-05-03
-
-New in the 0.9.10 x11vnc release:
-
-	IPv6 is now supported for all usage modes: forward and reverse
-		connections, SSL and unencrypted, etc.
-
-	The included SSL enabled Java VNC viewer applet now supports
-		Chained SSL Certificates (x11vnc -ssl always has.)
-		The applet autodects x11vnc and set GET=1 for faster
-		connecting via HTTPS.
-
-	A demo CGI script 'desktop.cgi' shows how to create an
-		SSL encrypted, multi-user x11vnc web login desktop
-		service.  The user logs into a secure web site and gets
-		his/her own virtual desktop and his browser accesses it
-		with the SSL Java VNC Viewer applet.
-
-	A serverCert Java Viewer applet parameter is provided.
-		Use an authenticated HTTPS browser connection to set
-		this parameter (the user could set it locally too.)
-		The onetimekey tool has -certonly option for this scheme.
-
-	The Xdummy script (use Xorg 'dummy' driver instead of Xvfb)
-		no longer requires being run as root.
-
-
-  miscellaneous new features and changes:
-
-	In the Java viewer applet, debugCerts and debugKeyboard parameters
-		are provided.  The debugging output of the applet is more
-		readable.  Some corner-case bugs (e.g. socket exceptions)
-		are now handled gracefully.  Parameters forbid_Ctrl_Alt
-		and mapF5_to_atsign are added.
-
-	The amount of time to wait for HTTPS applet downloads to finish
-		can be set in env. var. X11VNC_HTTPS_DOWNLOAD_WAIT_TIME.
-
-	The -xkb mode is automatically enabled if there are more than
-		4 keysyms per key.
-
-	-coe is now an alias for -connect_or_exit.
-
-	The -input_eagerly option enables this LibVNCServer feature
-		(it is like -allinput.)
-
-	The "%" unix password verification tricks for the -unixpw
-		option are now documented.  They also run a command
-		in UNIXPW_CMD.
-
-	In -create (-svc, etc.) modes, a warning is printed out if Xvfb
-		cannot be found.  Xvfb '+kb' option is checked for.
-		The -env CREATE_DISPLAY_OUTPUT=/tmp/mydebug.txt debugging
-		option is documented.  Try to preserve user's PATH
-		if possible.
-
-		In XDMCP connection mode, a test for GDM listening only
-		on IPv6 (::1) is performed.  The interface can also be
-		specified via FD_XDMCP_IF.
-
-	The example scripts connect_switch, ultravnc_repeater.pl, inet6to4
-		have settings to let them run reliably for long times
-		as daemons.  They also support IPv6.
-
-	IPv6 notes: for some very esoteric cases (e.g. -chatwindow)
-		IPv4 localhost may be required for local IPC.  A demo
-		transition tool 'inet6to4' is also included (can be
-		used for other apps.)  x11vnc options related to IPv6:
-		-listen6, -6, -no6, -noipv4, -noipv6, and -connect,
-		-proxy.
-
-	Use STUNNEL_LISTEN in -stunnel mode to have it listen on a
-		particular interface.  Also STUNNEL_PROG.
-
-	New remote control query options: pointer_x, pointer_y,
-		pointer_same, pointer_root, and pointer_mask. A demo
-		script using them misc/panner.pl is provided.
-
-	Remote control change of -clip option will not create new
-		framebuffer if the size has not changed (for panner.pl)
-
-	The X11VNC_DISABLE_SSL_CLIENT_MODE env. var. can be set to
-		disable SSL client role in reverse connections.  This
-		means the VNC viewer side must be in SSL client role.
-		UltraVNC repeater operation can benefit from this.
-
-		The SSL_INIT_TIMEOUT is increased to 1 hour if 'repeater'
-		is detected in a reverse connect string.
-
-	The X property X11VNC_TRAP_XRANDR can be set on a desktop to
-		force x11vnc to use the -xrandr screen size change
-		trapping code.
-
-	The -sslScripts option prints out the SSL certificate management
-		scripts.
-
-	Suggest '-auth guess' and '-findauth' if X connection fails.
-
-	The TightVNC sercurity type (TightVNC features enabler) now
-		works for RFB version 3.8.
-
-	RECORD scroll detection is now working with the new gtk/gdk scroll
-		mechanism.  Set X11VNC_SCROLL_MUST_EQUAL to disable.

-x11vnc 0.9.9	2009-12-21
-
-
-
-New in the 0.9.9 x11vnc release:
-
-	A new option -findauth runs the FINDDISPLAY script that applies
-		heuristics to try to determine the correct XAUTHORITY
-		file.  The use of '-auth guess' will use the XAUTHORITY
-		that -findauth reveals.  This can be handy in with
-		the lastest GDM where the ability to store cookies in
-		~/.Xauthority has been removed.
-
-		If x11vnc is running as root (e.g. inetd or XDM/GDM/KDM)
-		the FD_XDM=1 mode will be tried if the above -findauth
-		or '-auth guess' command fails; it will find the
-		correct XAUTHORITY for the given display (this works for
-		XDM/GDM/KDM if the login greeter panel is up or if someone
-		has already logged into an X session.)	You can also
-		set -env FD_XDM=1 to force it to be done on the first try.
-
-	The -unixpw_system_greeter option, when used in combined
-		unixpw and XDMCP FINDCREATEDISPLAY mode (e.g. -xdmsvc),
-		enables the user to press Escape to jump directly to the
-		XDM/GDM/KDM login greeter screen.  This way the user
-		avoids entering his unix password twice at X session
-		creation time.	For subseqent logins to the same session,
-		he uses the regular x11vnc unixpw "login:" prompt.   Also,
-		the unixpw login panel now has a short help displayed
-		if the user presses 'F1' that lists the options.
-
-	The -appshare option enables simple application sharing based on
-		the -id/-sid mechanism.  Every new toplevel window that
-		the application creates induces a new viewer window via
-		a reverse connection.  The -id/-sid and -connect options
-		are required.  Run 'x11vnc -appshare -help' for more info.
-
-	Heuristics are applied to try to determine if the X display
-		is currently in a Display Manager Greeter Login panel
-		(e.g. GDM.)  If so, x11vnc's creation of any windows and
-		use of XFIXES are delayed.
-
-		This is to try to avoid x11vnc being killed after the user
-		logs in if the GDM KillInitClients=true is in effect.
-		So one no longer needs to set KillInitClients=false in
-		gdm.conf.  Note that in recent GDM the KillInitClients
-		option has been removed.
-
-		Also delayed is the use of the XFIXES cursor fetching
-		functionality; this avoids an Xorg bug that causes Xorg
-		to crash right after the user logs in.
-
-	x11vnc now tries to be more aggressive in keeping up with VNC
-		client's framebuffer update requests.  Some broken VNC
-		clients continuously spray these requests at VNC servers
-		(regardless of whether they have received any updates
-		or not.)  The -extra_fbur option allows one to fine tune
-		the setting.
-
-	The "-display WAIT:cmd=...", -find, -create modes now work
-		correctly for the user-supplied login program scheme
-		"-unixpw_cmd ...", as long as the login program supports
-		running commands specified in the environment variable
-		"RFB_UNIXPW_CMD_RUN" as the logged-in user.  The mode
-		"-unixpw_nis ..." has also been made more consistent.
-		The username option "tag=..." can be used to set FD_TAG.
-
-	The -stunnel option (like -ssl but uses stunnel as an external
-		helper program) now works with the -ssl "SAVE" and "TMP"
-		special certificate names.  The -sslverify and -sslCRL
-		options now work correctly in -stunnel mode.  Single port
-		HTTPS connections are also supported for this mode.
-
-	The remote control command -R can be used to instruct x11vnc
-		to resend its most recent copy of the Clipboard,
-		Primary, or Cutbuffer selections: "x11vnc -R
-		resend_clipboard", "x11vnc -R resend_primary", and
-		"x11vnc -R resend_cutbuffer".
-
-  miscellaneous new features and changes:
-
-	The fonts in the GUI (-gui) can now by set via environment
-		variables, e.g. -env X11VNC_FONT_BOLD='Helvetica -16 bold'
-		and -env X11VNC_FONT_FIXED='Courier -14'.
-
-	The value of the -timeout option is now also used for the timing
-		out of reverse connections.  The -timeout exit will
-		occur if no client has made it to normal operating state
-		(instead of merely trying to connect.)
-
-	One can add extra URL parameters to the HTTPS (-ssl) urls
-		via X11VNC_EXTRA_HTTPS_PARAMS without needing to edit
-		index.vnc. E.g.: -env X11VNC_EXTRA_HTTPS_PARAMS='?GET=1'
-
-	One can make the libvncserver HTTP (non-SSL) server listen on
-		localhost: -env X11VNC_HTTP_LISTEN_LOCALHOST=1 (this way
-		only the single-port VNC+HTTPS is exposed to the network.)
-
-	Warnings are printed out at startup if $DISPLAY appears to
-		start with "localhost:" (SSH X11 forwarding) or 
-		"hostname:" (remote X display; will fail w/o -noshm)
-
-	The -solid option now uses the DBUS_SESSION_BUS_ADDRESS env. var
-		if available.  The -solid option now works in xfce.
-		If available, the dbus_launch(1) will be used in
-		FINDCREATEDISPLAY for gnome sessions.
-
-	The bcx_xattach remote control command was added to facilitate
-		xattach and x2x desktop cursor switching.  Other new
-		remote control commands: grab_state, ping:mystring,
-		grablocal, resend_cutbuffer, resend_clipboard,
-		resend_primary, keycode, keysym, fakebuttonevent,
-		ptr, sleep, get_xprop, set_xprop, wininfo, pointer_pos,
-		mouse_xy, noop, guess_dbus, DIRECT:query.  Remote control
-		scripting, -query_retries, and -remote_prefix were
-		also added.
-
-	In -rawfb mode the X display will not be opened at all unless
-		the -rawfb string is prefixed with '+' or -display
-		was specified on the cmdline.
-
-	For multiple, separate x11vnc instances on the same X display,
-		one can rename the X11VNC_REMOTE, X11VNC_TICKER, and
-		VNC_CONNECT property names to unique ones.
-
-	The -showrfbauth option prints out the VNC rfbauth password.
-
-	The XDAMAGE mechanism is now automatically disabled for a
-		period of time if a game or screensaver generates too
-		many XDAMAGE rectangles per second.  This avoids the X11
-		event queue from soaking up too much memory.
-
-	x11vnc does not switch on server autorepeat if any keys are
-		pressed down to work around a recent Xorg server and/or
-		gnome bug where the key will never stop repeating.
-
-	Thse list of current clients is kept more up-to-date in the
-		tkx11vnc gui.  Bugs in the gui setpass mode have been
-		fixed.
-
-	Threads stability is further improved.  See under the -threads
-		option help info about -env X11VNC_THREADS_NEW_FB_SLEEP=ms
-
-	There is an experimental workaround: "-env X11VNC_WATCH_DX_DY=1"
-		that tries to avoid problems with poorly constructed
-		menu themes that place the initial position of the mouse
-		cursor inside a menu item's active zone.
-
-	The crypt(3) function is now declared inside the x11vnc code on
-		all platforms (not just Linux).  To disable this, set
-		CPPFLAGS='-DDO_NOT_DECLARE_CRYPT' while configuring.
-		(crypt is declared to avoid problems with header files.)
-
-	Error reasons are printed for -storepasswd failures.
-
-	Two scripts are added to x11vnc/misc: connect_switch and
-		ultravnc_repeater.pl

-x11vnc 0.9.8	2009-07-08
-
-
-New in the 0.9.8 x11vnc release:
-
-	Better reliability for the Java Viewer applet when connecting
-		through a Web Proxy via HTTPS.	A proxy hostname
-		and port can be specified via applet parameters.
-		Proxy Authentication via Auth-Basic is supported.
-		More x11vnc printout in -ssl is provided to help
-		troubleshoot this mode and other ssl connections.
-
-	Stability improvements to -threads mode. Running x11vnc this
-		way is more reliable now. Threaded operation sometimes
-		gives better interactive response and faster updates. The
-		threaded mode now supports multiple VNC viewers using
-		the same VNC encoding (some only on Linux or enabled
-		at build time.)  The threaded mode can also yield
-		a performance enhancement in the many client case
-		(e.g. class-room broadcast.) We have tested with 30 to
-		50 simultaneous clients.  See also -reflect.
-
-
-  miscellaneous new features and changes:
-
-	x11vnc automatically tries to work around an Xorg server bug
-		involving infinitely repeating keys when turning off key
-		repeating. Use -repeat if the automatic workaround fails.
-		Also, the environment variable X11VNC_IDLE_TIMEOUT
-		(seconds) is provided.
-
-	In -reflect mode the environment variable X11VNC_REFLECT_PASSWORD
-		is provided.
-
-	The -clip mode works under -rawfb.
-
-	The -nounixpw option can disable unixpw mode if an earlier option
-		enables it (e.g. -svc).
-
-	Scroll detection is skipped for windows with 'OpenOffice' in
-		their name.

-
-x11vnc 0.9.7	2009-03-31
-
-
-New in the 0.9.7 x11vnc release:
-
-	Basic support for building with VirtualGL's TurboVNC (an
-		enhanced TightVNC for fast LAN high framerate usage)
-		encoding and TightVNC modifications.  More info:
-		http://www.karlrunge.com/x11vnc/faq.html#faq-turbovnc
-		and x11vnc/misc/turbovnc/README.
-
-	The -ncache_cr option has been fixed and so in -ncache mode
-		smooth opaque window motions are now work correctly. Try
-		it out to see how smooth it is even on a slow link.
-
-	Support for Linux text consoles (virtual terminals, e.g. 1-6)
-		is provided via, e.g., 'x11vnc -rawfb vt2' (for virtual
-		terminal #2).
-
-		This is like LinuxVNC (i.e. text only), it avoids using
-		/dev/fb and uses /dev/vcsaN instead (the '-rawfb console'
-		mode uses /dev/fb.)  With /dev/vcsaN the text terminal
-		is accessible even it if is not the currently active one.
-
-	The -rawfb option now supports framebuffers with bits per pixel
-		less than 8 (e.g. 4 or 1 bpp.)
-
-	Reverse connections now work in Anonymous Diffie Hellman SSL/TLS
-		mode.  Reverse connections also work for VeNCrypt and
-		ANONTLS modes.
-
-
-  miscellaneous new features and changes:
-
-	The included SSL enabled UltraVNC java viewer now has a
-		configurable [Home] entry in the drives drop down menu.
-
-	In the -create, -svc, etc. modes one can now specify a
-		range of X displays to ignore in X11VNC_SKIP_DISPLAY.
-		Improvements and bugfixes were made to the find_display
-		and create_display scripts.  FD_EXTRA option is provided.
-
-	The '-rawfb video' option finds the video device file more
-		carefully.
-
-	The -rmflag option allows a new way to indicate to other
-		applications that x11vnc has started.
-
-	All of the java applet parameters are now documented in
-		the classes/ssl/README file.
-
-	There is now a "sendbell" remote control command.
-
-	A one-time -padgeom once:WxH mode is added.
-
-	Improvements to the CUPS Terminal Services helper mode.
-
-	If the X display cannot be opened normally then the env. var.
-		XAUTHLOCALHOSTNAME=localhost is tried.
-
-	Bugfix for selection transfer to a now non-existent X window
-		(Thunderbird can cause this.)  Related, the env. variable
-		LIBXCB_ALLOW_SLOPPY_LOCK is now set by default.
-
-	Bugfix for -8to24 mode due to nonstandard indexed color support.
-
-	The libvncserver and x11vnc autoconf/automake settings have
-		been improved.
-
-	libXrandr include file is now found on Solaris.

-
-x11vnc 0.9.6	2008-12-10
-
-
-New in the 0.9.6 x11vnc release:
-
-	x11vnc's SSL encryption is extended to support the VeNCrypt and
-		TLS (older; vino) SSL/TLS security type extensions to VNC.
-
-	Anonymous Diffie-Hellman key exchange (-ssl ANON) and Certificate
-		Revocation List support (-sslCRL) is added to the SSL
-		encryption mode.
-
-	The Java viewer applet can now be served up through the VNC port
-		(5900) in addition to the normal HTTP port (5800) via
-		the -http_oneport option.  Previously this only worked
-		for SSL connections and HTTPS.
-
-	The "-rfbport PROMPT" mode presents a simple gui for the user
-		to select a port for the x11vnc service and a few other
-		settings.  This enables a menu entry for naive users
-		that is included in x11vnc.desktop.
-
-	If x11vnc is not built with the Avahi Zeroconf library an external
-		helper program (avahi-publish or dns-sd on Mac OS X)
-		is used instead.
-
-  miscellaneous new features and changes:
-
-	The default mode for '-ssl' is now the '-ssl SAVE' mode; i.e.
-		the generated certificate is saved and reused in
-		subsequent sessions rather than being discarded.
-		Use '-ssl TMP' recover the old way.  This change made
-		to for it to be more likely that the VNC Viewer can save
-		the accepted cert for future authentications.
-
-	The solid background color option works on the Mac OS X console.
-
-	The -reopen option enables x11vnc to try to re connect to the X
-		display if GDM (or other display manager) kills it just
-		after the user logs in.
-
-	The -dhparams option can be used to point to your own Diffie
-		Hellman parameters.
-
-	The -setdefer option allows tuning how quickly updates will
-		be sent.  Default setting tuned.
-
-	The option -zeroconf is now an alias for -avahi/-mdns.
-
-	In pipeinput mode, the pipe filehandle is now closed when
-		x11vnc exits.
-
-	The -sshonly option turns off VeNCrypt and TLSVNC (vino) mod
-		leaving only the standard SSL (i.e. vncs://)
-
-	For testing, the option -rand in an alias for -rawfb rand -nopw
-
-	Minor tweaks to improve CUPS Print tunneling.

-x11vnc 0.9.5	2008-10-24
-
-
-New in the 0.9.5 x11vnc release:
-
-	Symmetric key encryption using the RC4, AES, Blowfish, and 3DES
-		ciphers is supported via the -enc cipher:keyfile option.
-		The SSVNC unix viewer 1.0.20 and later supports these
-		encryption methods.
-
-	Server-side scaling can now have different scale factors along
-		the horizontal and vertical axes.  E.g. -scale 1280x1024
-		(same as -geometry 1280x1024) or -scale 0.8x0.75
-
-	The -chatwindow option allows a chat window to appear on the
-		X console during UltraVNC chats (requires the SSVNC
-		viewer package.)
-
-  miscellaneous new features and changes:
-
-	The HTTP Java viewer applet jar, classes/VncViewer.jar, has
-		been updated with an improved implementation based on
-		the code used by the classes/ssl applets.
-
-	A description and instructions are now printed out when
-		X_ShmAttach fails if one tries to attach to a remote
-		$DISPLAY (i.e. $DISPLAY is on a different machine from
-		the machine x11vnc is running on; this often happens
-		with SSH X redirection, X terminal servers, etc).
-
-	The -allow option now works correctly in -ssl mode.
-
-	The -remap option now works on the MacOSX console.

-x11vnc 0.9.4	2008-09-17
-
-
-New in the 0.9.4 x11vnc release:
-
-	Reverse VNC connections (-connect and  -connect_or_exit options)
-		work in the -find and -create X session FINDCREATEDISPLAY
-		modes.
-
-	Reverse VNC connections (either normal or using SSL) can use a
-		Web Proxy, a SOCKS proxy, the UltraVNC repeater proxy,
-		an SSH connection, or even a CGI URL to make the outgoing
-		connection (-proxy option).  Forward connections can
-		use the -ssh option to set up a reachable redirection.
-
-	Support for the ZYWRLE encoding is added, this is the RealVNC ZRLE
-		encoding extended to do motion video and photo regions
-		more efficiently by way of a Wavelet based transformation.
-
-	The session finding and creating modes (-find and -create) have
-		been improved to be more reliable and also provide a new
-		desktop types (xfce) and new service redirection options.
-
-	Support for indexed colormaps (PseudoColor) with depths other
-		than 8 is provided (depths 1 to 16 now work).
-
-	Java viewer applet source code is provided in the x11vnc 0.9.4
-		tarball so now everything can be built from source.  
-
-  miscellaneous new features and changes:
-
-	To unset Caps_Lock, Num_Lock and raise all keys in the X server
-		use -clear_all, or by remote control 'x11vnc -R clear_all'
-
-	The -autoport option gives more control over the server port
-		range that probes.
-
-	The -ping option can be used to help keep idle connections alive.
-
-	The -finddpy and -listdpy utilities help to debug and configure
-		the -find, -create, and -display WAIT:... modes.
-
-	Some automatic detection of screen resizes are handled even if
-		the -xrandr option is not supplied.
-
-	The -advertise_truecolor option can workaround some VNC viewer
-		incompatibilities with PseudoColor.
-
-	The option '-clip xinerama0' can be used to clip to the first
-		Xinerama sub-screen, etc.
-
-	If a fast framebuffer read rate is detected the -wait and -defer
-		parameters are reduced to 10 and 15 msec, respectively.
-
-	Pasting of the selection/clipboard into remote applications
-		(e.g. Java) is improved.
-
-	Usage with dvorak keyboards is improved.  The option -macuskbd is
-		available on MacOSX to use the original US keyboard code.
-
-	Via a compiler option (-DENABLE_GRABLOCAL) one can use the
-		-grablocal n option to filter VNC client input if someone
-		at the console has done mouse or keyboard input n secs ago. 
-
-	The -sleepin option can now sleep a random amount of time between
-		min and max time delays (-sleepin min-max).

-x11vnc 0.9.3	2007-10-04
-
-
-New in the 0.9.3 x11vnc release:
-
-	This release provides client-side caching to improve interactive
-	response.  Almost no VNC viewers implement caching which is why
-	VNC is slow compared to other remote graphics protocols.
-
-	The x11vnc caching will work with any VNC viewer, but they will
-	not hide the pixmap cache region that is below the main desktop
-	(one must adjust the window manually).  The SSVNC Unix VNC viewer,
-	however, automatically detects and hides the region.
-
-	To enable caching, supply "-ncache n" to x11vnc, where the
-	number n, e.g. 10, indicates how much memory to devote to the
-	caching scheme.
-
-	See http://www.karlrunge.com/x11vnc/#faq-client-caching

-x11vnc 0.9.2	2007-06-18
-
-
-New in the 0.9.2 x11vnc release:
-
-	A compile-time bug is fixed for when the OpenSSL library is not
-		available or --without-ssl is supplied; previously the
-		build would fail.
-
-	One can configure x11vnc via "configure --with-system-libvncserver"
-		to use a system installed libvncserver library instead of
-		the one bundled in the release tarball. 
-
-	If UltraVNC file transfer or chat is detected, then VNC clients
-		are "pinged" more often to prevent these side channels
-		from becoming serviced too infrequently.
-
-	In -unixpw mode in the username and password dialog no text will
-		be echoed if the first character sent is "Escape".  This
-		enables a convenience feature in SSVNC to send the username
-		and password automatically.  
-
-  miscellaneous new features and changes:
-
-	When building from the CVS tree --with-x11vnc must be supplied if
-		you want x11vnc to be built.  The LibVNCServer release
-		tarball no longer contains the x11vnc source.

-x11vnc 0.9.1	2007-05-24
-
-
-New in the 0.9.1 x11vnc release:
-
-	A new Unix username identification scheme is provided when
-		SSL client certificates are used to authenticate VNC
-		viewers.  The username is extracted from the 'Subject'
-		section of the cert.  The option is "-users sslpeer="
-		which, like "-users unixpw=" already does, will cause
-		a switch to the Unix user.  This is useful for the
-		-find and -create options that try to find an existing
-		X session associated with the user or create a new one.
-
-	The UltraVNC Java Viewer has been modified to support SSL
-		connections.  Some bugs were also fixed and some
-		improvements added.  A patch file and a compiled jar file
-		(UltraViewerSSL.jar and SignedUltraViewerSSL.jar in the
-		classes/ssl directory) are provided in the x11vnc package.
-
-	For the -user option groups are now handled better by using
-		initgroups(3), or if finer control is needed one can
-		use: "-users user1.group1,..."
-
-	When SSL client certification is being used and external login
-		programs are being used the env. var. RFB_SSL_CLIENT_CERT
-		is set to the clients certificate.  Set X11VNC_SSLPEER_CN
-		to use the Common Name instead of the certificate email
-		address to find the unix username.
-
-  miscellaneous new features and changes:
-
-	The -wait and -defer defaults were lowered from 30 to 20
-		milliseconds, set the values explicitly if this increases
-		the load too much for your liking.
-
-	In -create mode where a Xvfb session is started, mwm was added
-		as a session type.  setpgrp(2) is used for the spawned
-		process if available.  The XKEYBOARD extension is 
-		enabled (+kb, but it doesn't seem to always work).
-		TrueColor is forced to be the default visual (recent
-		Xvfb seem to choose DirectColor, this is likely a bug)
-		One can also force creating a new Xvfb by setting the
-		env. var. X11VNC_FINDDISPLAY_ALWAYS_FAILS (not exactly
-		clear what this would be used for). 
-
-	The WAITBG env. var. enables -display WAIT:... to take place in
-		the background.
-
-	One can specify the X11VNC_SKIP_DISPLAY env. var. for a list of
-		displays to exclude in the FINDDISPLAY action.	This can
-		also be specified via nd=... as a -unixpw login option.
-
-	setsid() or setpgrp() is called for the external command spawned
-		by the -gone option (since it may be long lived, e.g. a
-		screen locker).
-
-	The script "onetimekey" utility is provided in the classes/ssl
-		subdirectory that allows a (very long) string representing
-		a Client SSL certificate to be provided by the authenticating
-		client, or via https cgi script (e.g. after a web login).
-
-	Some bugs were fixed in the libvncserver implementation of
-		UltraVNC file transfer.

-New in the 0.9 x11vnc release:
-
-	VNC Service advertising via mDNS / ZeroConf / BonJour with the
-		Avahi client library. Enable via "-avahi".
-
-	Implementations of UltraVNC's TextChat, SingleWindow, and
-		ServerInput extensions (requires ultravnc viewer or ssvnc
-		Unix viewer). They toggle the selection of a single window
-		(-id), and disable (friendly) user input and viewing
-		(monitor blank) at the VNC server.
-
-	Short aliases "-find", "-create", "-svc", and "-xdmsvc" for
-		commonly used FINDCREATEDISPLAY usage modes (to find
-		the user's display or create one, etc).
-
-	Reverse VNC connections (viewer listening) now work in SSL
-		(-ssl) mode.
-
-  miscellaneous new features and changes:
-
-	New options to control the Monitor power state and keyboard/mouse
-		grabbing: -forcedpms, -clientdpms, -noserverdpms,
-		and -grabalways.
-
-	A simple way to emulate inetd(8) to some degree via the "-loopbg"
-		option.
-
-	Monitor the accuracy of XDAMAGE and apply "-noxdamage" if it is
-		not working well. OpenGL applications like like beryl and
-		MythTv have been shown to make XDAMAGE not work properly.
-
-	For Java SSL connections involving a router/firewall port
-		redirection, an option -httpsredir to spare the user
-		from needing to include PORT=NNN in the browser URL.
-
-	A -sleepin n option to delay startup by n seconds to let redirs
-		and listening clients to get started.
-
-	TightVNC file transfer is now off by default; enable via
-		-tightfilexfer

-x11vnc 0.8.4	2007-02-01
-
-
-New in the 0.8.4 x11vnc release:
-
-	Native Mac OS X Aqua/Quartz support.  It exports the full
-		display (no X11 server, etc).
-
-		This provides an alternative to OSXvnc; some activities
-		are faster (and see the client-side caching feature
-		-ncache in the 0.8.5 development version for more
-		speedups).
-
-	x11vnc can act as a VNC reflector/repeater using the
-		"-reflect host:N" option.  This is useful for large
-		classroom broadcasting or demos.  You set up a number
-		of reflectors to spread the network and CPU load around
-		for better response.
-
-	A new login mode: "-display WAIT:cmd=FINDCREATEDISPLAY -unixpw ..."
-		that will Create a new X session (Xvfb, Xdummy, or
-		Xorg) for the user if it cannot find the user's X
-		session display via the FINDDISPLAY method.  It will
-		be re-found upon reconnection.
-
-		This enables a simple "terminal services" mode based on
-		Unix username and password and where the user does not
-		have to memorize their VNC display number, etc.
-
-
-  miscellaneous new features and changes:
-
-	Option -nodpms to avoid problems with programs like KDE's
-		kdesktop_lock that keep restarting the screen saver
-		every few seconds even with active VNC clients connected.
-
-	The "-N" option couples the VNC Display number to the X Display
-		number. E.g. if your X DISPLAY is :2 then the VNC display
-		will be :2 (i.e. using port 5902). If that port is taken
-		x11vnc will exit.
-
-	Wireframe copyrect detection for local user activity (e.g. someone
-		sitting at the physical display moving windows).  You
-		can disable this with the -nowireframelocal option.
-
-	To automatically fix the common mouse motion problem on XINERAMA
-		(multi-headed) displays, the -xwarppointer option is
-		enabled by default when XINERAMA is active.  You can
-		disable this with the -noxwarppointer option.
-
-	By default in -reflect mode -shared is implied (it makes sense),
-		use -noshared after the -reflect option to disable this. 
-
-	The -prog option lets you specify the full path (argv[0]) to
-		the program, in case it is spawned by inetd/tcpd and
-		cannot determine its path.  The path is needed for the
-		-http option to guess the http classes directory.
-
-	Usually not needed, but there are many options for tuning the
-		native Mac OS X mode: -macnodim -macnosleep -macnosaver
-		-macnowait -macwheel -macnoswap -macnoresize -maciconanim
-		-macmenu.
-
-	An option -debug_xdamage has been added for debugging and profiling.

-
-x11vnc 0.8.3	2006-11-13
-
-
-New in the 0.8.3 x11vnc release:
-
-	The -ssl option provides SSL encryption and authentication
-		natively via the www.openssl.org library.  One can use
-		from a simple self-signed certificate server certificate
-		up to full CA and client certificate authentication schemes.
-
-	The -sslverify option allows for authenticating VNC clients via
-		their certificates in either -ssl or -stunnel modes.
-
-	Certificate creation and management tools are provide in the
-		-sslGenCert, -sslGenCA, and related options.
-
-	An SSL enabled Java applet VNC Viewer applet is provided in
-		classes/ssl/VncViewer.jar.
-
-		The applet may also be loaded into the web
-		browser via HTTPS, i.e one can use the VNC port,
-		e.g. https://host:5900/
-
-		See our "Enhanced TightVNC Viewer" project, for native
-		SSL enabled viewers.
-
-	The -unixpw option supports Unix username and password
-		authentication. The -ssl or -localhost and -stunnel
-		options (or detection of an SSH tunnel) are enforced in
-		this mode to prevent password sniffing.
-
-	Coupling -unixpw with -display WAIT:cmd=FINDDISPLAY provides a
-		way to allow a user to login with their UNIX password
-		and have their display connected to automatically.
-
-	Hooks are provided in the -unixpw_cmd and "-passwdfile cmd:,custom:..."
-		options to allow you to supply your own authentication
-		and password lookup programs (e.g. LDAP).
-
-	The "-ultrafilexfer" alias is provided and improved UltraVNC
-		filetransfer rates have been achieved.
-
-	The -rotate option enables you to rotate or reflect the screen
-		before exporting via VNC. This is intended for use on
-		handhelds and other devices where the rotation orientation
-		is not "natural".
-
-  miscellaneous new features and changes:
-
-	Similar to -ssl, the -stunnel option starts up a SSL tunnel server
-		stunnel (that must be installed separately on the system)
-		to allow only encrypted SSL connections from the network.
-
-	Option -sslnofail to exit immediately if there are any SSL
-		connection failures.
-
-	A simpler variant of -unixpw is the -unixpw_nis option that
-		works in environments where the encrypted passwords are
-		readable, e.g. NIS.
-
-	x11vnc can be configured and built to not depend on X11 libraries
-		"./configure --without-x" for -rawfb only operation
-		(e.g. embedded linux console devices).
-
-	Add -cursor_drag to change the mouse cursor during Drag and Drop, etc.
-
-	Under the "-connect_or_exit host" option x11vnc will exit
-		immediately unless the reverse connection to host
-		succeeds. The "-rfbport 0" option disables TCP listening
-		for connections (useful for this mode).
-
-	The "-rawfb rand" and "-rawfb none" options are useful for
-		testing automation scripts, etc., without requiring a
-		full desktop.
-
-	Reduced spewing of information at startup, use "-verbose" (also
-		"-v") to turn it back on for debugging.

-x11vnc 0.8.2	2006-07-13
-
-
-New in the 0.8.2 x11vnc release:
-
-	Support for full mouse and keyboard input into the Linux
-		console framebuffer /dev/fb0 in -rawfb mode
-		(i.e. non-X11) by using the Linux "uinput" driver.
-
-		This enables, for example, viewing and interacting
-		with Qt-embedded/Qtopia-Core apps on Linux-based
-		handhelds, etc.
-
-		Options:   -rawfb cons, -pipeinput UINPUT More info:
-		http://www.karlrunge.com/x11vnc/#faq-qt-embedded
-
-	Extension of the display option: -display WAIT:<disp-or-cmd>
-		to delay x11vnc's opening of the X display
-		until a VNC client connects (useful built-in:
-		-display WAIT:cmd=FINDDISPLAY, to find a user's
-		display and Xauthority data).
-
-	Options -grabkbd and -grabptr have x11vnc try to grab
-		the X display when VNC clients are connected to
-		prevent a (non-malicious) user at the physical X
-		display from performing keyboard or mouse input.
-		E.g. remote help-desk support.
-	
-
-  miscellaneous new features and changes:
-
-	-allowedcmds option to fine-tune which external commands
-		may be run by x11vnc, rather than shutting
-		them all off with -nocmds.
-
-	-env VAR=VALUE convenience option to avoid the need of
-		setting environment variables before starting
-		x11vnc.
-
-	-allinput option to enable libvncserver handleEventsEagerly
-		parameter (not clear it yields an improvement).
-
-	-rawfb rand  fun/testing option using /dev/urandom as a fb.
-
-	-license, -copying, -warranty option.

-x11vnc 0.8.1	2006-06-03
-
-New in the 0.8.1 x11vnc release:
-
-	Improved support for webcams and tv tuners with video4linux
-		/dev/video: see the "-rawfb video" and "-pipeinput VID"
-		options. (the latter gives a simple keyboard control
-		of a tv tuner; see also the -freqtab option for stations).
-
-	FBPM support for hardware that provides framebuffer power
-		management (it needs to be disabled when vnc clients
-		are connected).
-
-	The -usepw option will require x11vnc to use a password of 
-		some sort or otherwise exit immediately.  Put it in
-		your ~/.x11vncrc so you don't forget.
-
-	The command "x11vnc -storepasswd" will prompt for a password
-		without echoing and save it in ~/.vnc/passwd
-
-	The X CLIPBOARD selection is managed in addition to the
-		X PRIMARY selection.
-
-
-  miscellaneous new features and changes:
-
-	Convenience option for accessing the Linux console: -rawfb cons
-		etc. (requires /dev/fb0 to be working).
-
-	clipboard/cut-text input can now be managed on a per-client
-		basis.
-
-	-capslock and -skip_lockkeys options can help make CapsLock work
-		better.
-
-	The Xdummy wrapper script is included in the source tree.
-
-	A mode "-gone popup" as been added.
-
-	-24to32 option to avoid 24bpp problems.
-
-	-xinerama is on by default.

-x11vnc 0.8	2006-02-13
-
-
-New in the 0.8 x11vnc release:
-
-	TightVNC file transfer support is enabled via the extension to
-		LibVNCServer added by Rohit Kumar.
-
-	The -passwdfile option has been enhanced to handle any number
-		of full-access and view only passwords in an easy to
-		maintain format, and additional features.
-
-	The -8to24 option enables multi-depth viewing on systems that do
-		not support -overlay. The 8bpp regions are transformed
-		to depth 24 TrueColor before exporting via VNC.
-
-	The x11vnc source code has gone through a major reorganization.
-		The build has been enhanced and many bugs fixed.
-
-
-  miscellaneous new features and changes:
-
-	-afteraccept option is like -accept however it enables running
-		a user supplied command after client authentication
-		has taken place. The RFB_* environment variables have
-		been extended.
-	-loop option will run x11vnc in an outer loop restarting each time
-		(useful for situations where the X server restarts often).
-	-slow_fb allows for slow polling for special purpose applications
-		(e.g. video).  -blackout noptr,WxH+X+Y,... will prevent
-	the pointer from going into a blacked out region.

-
-x11vnc 0.7.2	2005-07-11
-
-
-New in the 0.7.2 x11vnc release:
-
-	The X DAMAGE extension is supported to dramatically reduce
-		resource consumption when idle: often 20 times less;
-		and to pick up small changed regions more quickly.
-
-		DAMAGE sends events indicating damaged (modified) screen
-		rectangles to x11vnc.  These are used as hints to focus
-		the polling and also if the rectangle is below a size
-		threshold it is accepted unconditionally (i.e. dragged in
-		from the framebuffer).	Tuning is possible with -xd_area.
-
-		DAMAGE is available on recent Xorg servers and Solaris 10.
-
-	-wireframe: Heuristics are used to guess when a window is being
-		moved or resized and during this period show only a
-		moving wireframe outline.  Just like on video cards in
-		the 90's, remember?  This is to avoid window "lurching"
-		when you move or resize one opaquely.
-
-		Also, -wirecopyrect applies the VNC CopyRect encoding
-		for the moved window.  Both are on by default, use
-		-nowireframe or -nowirecopyrect to disable (aka -nowf
-		and -nowcr).
-
-	-scrollcopyrect: Sniff the X11 protocol via the RECORD extension
-		and to try to detect window scrolls (e.g. via scrollbar,
-		Up/Down arrow, etc).  When detected, the VNC CopyRect
-		encoding is applied to the scrolled regions for a speedup.
-
-		The contents of the scrolling window may only be
-		approximate while it is being scrolled: e.g. tearing,
-		bunching-up, etc.  The heuristics will also miss scrolls
-		by certain toolkits or applications, so those will still
-		happen the slow way.  To disable use -noscrollcopyrect
-		(aka -noscr).  Tuning is also available, see the -help
-		entry.
-
-	-listen: Makes x11vnc listen only on a single network interface.
-		-localhost now implies '-listen localhost'.
-
-	-rawfb: Instead of polling an X server framebuffer, poll a raw
-		one (i.e. a mapped file or a shm segment).  E.g. for
-		the linux framebuffer device:
-
-		    -rawfb map:/dev/fb0@1024x768x32
-
-		This is a bit out of x11vnc's scope but may have some
-		interesting applications.  Perhaps /dev/video?
-
-	-pipeinput: Pipe the VNC user's pointer and keyboard input events
-		to a helper program you provide.  Two examples are in
-		misc/vcinject.pl and misc/slide.pl.  Primarily intended
-		for use with -rawfb to somehow kludge-up user input,
-		but it can also be used by itself.
-
-	Improvements for the magnification scaling case (e.g. -scale 2)
-		for use in low vision applications.  It is faster and
-		no-blending :nb now works correctly.
-
-	More safety measures are taken WRT remote-control in the
-		default mode.  See the -unsafe, -safer, -privremote,
-		and -nocmds options.
-
-	The GUI has been improved, and running with the options "-gui icon"
-		presents a small, simple gui instead of the full blown one,
-		and "-gui tray" attempts to embed the small icon in the
-		system tray.  Use "-gui tray=setpass" to prompt for
-		session password creation at startup.
-
-
-  miscellaneous new features and changes:
-
-	-xkb: a simple test is performed at startup to see if it is a
-		good idea to apply -xkb mode for the current keyboard
-		keymapping (i.e. if keysyms like !, @, [ are otherwise
-		unavailable).  To disable use -noxkb.
-	 ISO_Level3_Shift vs. Mode_switch:  Set things up in -xkb mode to
-		prefer ISO_Level3_Shift over Mode_switch for modtweaking.
-		No override; let me know if this causes problems.
-	-add_keysyms is now the default, use -noadd_keysyms to disable.
-		the added keysyms are periodically deleted.
-	-remap DEAD: shorthand for mapping many "dead" keysyms to their
-		"un-dead" counterparts, e.g. grave -> dead_grave.  For
-		some VNC viewers that are unable to send the dead keysym.
-	-skip_dups: skip impossible duplicate key events sent by some VNC
-		viewers. -noskip_dups to disable (currently off by default).
-	-sloppy_keys: try to handle sloppy keyboarding (esp. between
-		different language keyboards) where, say, Shift is released
-		before the key.
-	-norepeat N: ping-pong N times if something else on the desktop
-		restores key autorepeating (e.g. session startup). Default
-		2.  Also, If the VNC client is idle for 5 min. autorepeat
-		is restored.
-	-wait_ui: If there is very recent user input, cut the -wait sleep
-		time by the specified factor (default 2.0).
-	-nowait_bog: Detection is now in place to watch for polling "bogging
-		down" (e.g. lots of scrolling text from a long build in a
-		terminal) and to sleep more.  Use -nowait_bog to disable.
-	-flag: write PORT=5900 to a flag file to aid wrapper scripts.
-	-http: try to guess what the -httpdir should be and if found
-		enable http listening.
-	-clip WxH+X+Y: only show the specified rectangle not the
-		entire screen.
-	 cursors are now scaled by default under -scale, use -scale_cursor
-		to modify this behavior.
-	-arrow n: select from some different arrow cursors (ignored under
-		XFIXES cursor grabbing mode).
-	-nolookup: disable DNS lookups for broken environments.
-	-seldir: fine tune and debug selection transfer. 
-	 build-time customization macros: SHARED, FOREVER, NOREPEAT,
-		REMOTE_CONTROL, SMALL_FOOTPRINT, default passwd, etc.
-		see the top of the x11vnc.c for more info.
-	-xtrap: DEC-XTRAP extension is supported for legacy systems
-		with insufficient XTEST extension (X11R5).
-	-shiftcmap: for legacy systems with non-standard colormap values.
-	-noxrecord: do not use the RECORD extension for anything (currently
-		only -scrollcopyrect and grabserver watching use it).
-	-grab_buster: fork a helper thread to watch for XGrabServer deadlock
-		in x11vnc and break the grab.  Under -scrollcopyrect there
-		is a small window where x11vnc is vulnerable to this deadlock.
-	-dbg:   A "crash shell" with tips on debugging will be presented
-		instead of exiting when a fatal error occurs.	
-	-fixscreen: periodically refresh the screen to get rid of painting
-		errors, etc. induced by new features, jpeg compression, etc.
-	-speeds: Tell x11vnc what the network and fb speeds are instead of
-		having it try to measure them.  (these speeds are used by
-		various features, such as -wireframe, -scrollcopyrect, etc.).
-	-wmdt: set the window manager or desktop to spare x11vnc from guessing.
-	-readtimeout: set libvncserver's read timeout parameter, useful on
-		very slow links that take more than 20secs to paint
-		the whole screen.
-	-nopw: If you use x11vnc without a password it now prints out a
-		scary warning message.  Use -nopw to disable the warning.
-	 plugged X event leaks; periodically purge any remaining buildup.

-x11vnc 0.7.1	2005-02-24
-
-
-New in the 0.7.1 x11vnc release:
-
-	Improved algorithm for approximating XFIXES cursors with
-		transparency (alpha channel).  No more ugly black fuzz
-		around translucent cursors.  Tuning parameters -alpha*
-		if it is still not right.
-
-	Added mechanisms to handle XFIXES cursors with transparency
-		exactly (i.e. blend in the background).  Works by default
-		under -nocursorshape updates, and also works under limited
-		circumstances for cursorshape updates if the VNC viewer
-		is patched (TightVNC viewer patch provided).
-
-	-solid: to improve performance switch the background to a solid
-		color when clients are connected.  Works on GNOME, KDE,
-		CDE, and classic X.
-
-	-input: allows fine-tuning the type of allowed user input
-		(Keystroke, Mouse-motion, Button-click).  Useful for
-		certain applications of x11vnc, e.g. demos. Also
-		per-client settings via -R input:xyz..
-
-	-users: enables switching to different users if started as root.
-		Please read the description for details.
-
-	-gui ez: less daunting GUI with fewer options via '-gui ez' or
-		"Misc -> simple-gui" once started.
-
-  miscellaneous new features and changes:
-
-	-nap is now the default, use -nonap to disable.
-	-snapfb: snapshot h/w fb to RAM periodically, not clear how useful...
-	-timeout n: for use in certain applications, exit if no client
-		connects after n seconds.
-	-oa and -logappend for appending to logfiles.
-	-opts will just show the options w/o the long -help descriptions.
-	if you forget to set -display, it will beep and try :0 after a bit.

-x11vnc 0.7	2004-12-23
-
-
-New in the 0.7 x11vnc release:
-
-	Support for the XFIXES X extension to show the exact mouse cursor
-		shape.  Requires libXfixes.  For approximate cursor
-		shapes also see: -cursor (none|arrow|X|some|most)
-
-	-remote/-R: remote-control support: nearly every setting can be
-		changed dynamically without restarting x11vnc.	For
-		example, "x11vnc -R shared", and "x11vnc -R scale:3/4"
-		will connect to a running x11vnc server to make it shared
-		and re-scaled, respectively.
-
-	-gui: launches a simple tcl/tk GUI based on the remote control
-		function.  Requires the tcl/tk "wish" program.
-
-	-overlay: support for overlay/multi-depth (e.g. 24+8) visuals
-		on Solaris (SUN_OVL extension) and IRIX.
-
-	-xrandr: support for the XRANDR (X Resize, Rotate and Reflection)
-		extension: if the screen changes size or rotates x11vnc
-		creates a new framebuffer to match it.  Useful to have a VNC
-		Viewer that supports NewFBSize extension. (also -padgeom)
-
-	-pointer_mode: Experimental pointer input handling schemes,
-		e.g.: "-pointer_mode 3" (similar to -nodragging)
-
-	man page x11vnc.1 and README files created.
-
-  miscellaneous new features and changes:
-
-	-sb: set screen blank idle timeout
-	-nocursorshape: disable cursor shape VNC extension.
-	RFB_MODE = "accept" or "gone" passed to -accept/-gone commands.
-        -vncconnect is now the default.
-        -norepeat is now the default.
-	"-id pick" to pick a window via xwininfo for the -id option. 
-	-sid option: like -id but crops root window instead.
-	Related to remote-control: -query, -noremote, -sync, 
-		-deny_all, -safer, -unsafe.

-
-  new keyboard related features:
-
-	-modtweak is now the default (it automatically adjusts the modifier
-		keys state to send a Keysym properly, disable -nomodtweak)
-		this works around "ghost" keys like "< >" in XFree86.
-
-	-xkb option to use XKEYBOARD extension for modtweak-ing to further
-		improve the accuracy of sending Keysyms between different
-		language keyboards.
-
-	-skip_keycodes and -add_keysyms options to fine tune stubborn
-		keyboard differences.
-
-	-norepeat option to turn off X server key autorepeat when clients
-		are connected (works around the repeated characters problem)

-"\n"
-"  Both the -connect option and the -id (or -sid) option are required.\n"
-"  (However see the -control option below that can replace -connect.)\n"
-"\n"
-"  The VNC viewer at viewer_host MUST be in 'listen' mode.  This is because\n"
-"  a new VNC connection (and viewer window) is established for each new\n"
-"  toplevel window that the application creates.  For example:\n"
-"\n"
-"       vncviewer -listen 0\n"
-"\n"
-"  The '-connect viewer_host:0' indicates the listening viewer to connect to.\n"
-"\n"
-"  No password should be used, otherwise it will need to be typed for each\n"
-"  new window (or one could use vncviewer -passwd file if the viewer supports\n"
-"  that.)  For security an SSH tunnel can be used:\n"
-"\n"
-"       ssh -R 5500:localhost:5500 user@server_host\n"
-"\n"
-"  (then use -connect localhost:0)\n"
-"\n"
-"  The -id/-sid option is as in x11vnc(1).  It is either a numerical window\n"
-"  id or the string 'pick' which will ask the user to click on an app window.\n"
-"  To track more than one application at the same time, list their window ids\n"
-"  separated by commas (see also the 'add_app' command below.)\n"

-"      -noexit        Do not exit if the main app (windowid/pick) window\n"
-"                     goes away.  Default is to exit.\n"
-"      -display dpy   X DISPLAY to use.\n"

-"  with the cmd=add_client:<client> and cmd=del_client:<client> commands.\n"
-"  Note that '-control internal' is required for '-shell' mode.  Using\n"
-"  '-control shell' implies internal mode and -shell.\n"
-"\n"
-"  Limitations:\n"
-"\n"
-"     This is a quick lash-up, many things will not work properly.\n"
-"\n"
-"     The main idea is to provide simple application sharing for two or more\n"
-"     parties to collaborate without needing to share the entire desktop.  It\n"
-"     provides an improvement over -id/-sid that only shows a single window.\n"
-"\n"
-"     Only reverse connections can be done.  (Note: one can specify multiple\n"
-"     viewing hosts via: -connect host1,host2,host3 or add/remove them\n"
-"     dynamically as described above.)\n"
-"\n"
-"     If a new window obscures an old one, you will see some or all of the\n"
-"     new window in the old one.  The hope is this is a popup dialog or menu\n"
-"     that will go away soon.  Otherwise a user at the physical display will\n"
-"     need to move it. (See also the SSVNC viewer features described below.) \n"
-"\n"
-"     The viewer side cannot resize or make windows move on the physical\n"
-"     display.  Again, a user at the physical display may need to help, or\n"
-"     use the SSVNC viewer (see Tip below.)\n"
-"\n"
-"     Tip: If the application has its own 'resize corner', then dragging\n"
-"          it may successfully resize the application window.\n"
-"     Tip: Some desktop environments enable moving a window via, say,\n"
-"          Alt+Left-Button-Drag.  One may be able to move a window this way.\n"
-"          Also, e.g., Alt+Right-Button-Drag may resize a window.\n"
-"     Tip: Clicking on part of an obscured window may raise it to the top.\n"
-"          Also, e.g., Alt+Middle-Button may toggle Raise/Lower.\n"
-"\n"
-"     Tip: The SSVNC 1.0.25 unix and macosx vncviewer has 'EscapeKeys' hot\n"
-"          keys that will move, resize, raise, and lower the window via the\n"
-"          x11vnc -remote_prefix X11VNC_APPSHARE_CMD: feature.  So in the\n"
-"          viewer while holding down Shift_L+Super_L+Alt_L the arrow keys\n"
-"          move the window, PageUp/PageDn/Home/End resize it, and - and +\n"
-"          raise and lower it.  Key 'M' or Button1 moves the remote window\n"
-"          to the +X+Y of the viewer window.  Key 'D' or Button3 deletes\n"
-"          the remote window.\n"
-"\n"
-"          You can run the SSVNC vncviewer with options '-escape default',\n"
-"          '-multilisten' and '-env VNCVIEWER_MIN_TITLE=1'; or just run\n"
-"          with option '-appshare' to enable these and automatic placement.\n"
-"\n"
-"     If any part of a window goes off of the display screen, then x11vnc\n"
-"     may be unable to poll it (without crashing), and so the window will\n"
-"     stop updating until the window is completely on-screen again.\n"
-"\n"
-"     The (stock) vnc viewer does not know where to best position each new\n"
-"     viewer window; it likely centers each one (including when resized.)\n"
-"     Note: The SSVNC viewer in '-appshare' mode places them correctly.\n"
-"\n"
-"     Deleting a viewer window does not delete the real window.\n"
-"     Note: The SSVNC viewer Shift+EscapeKeys+Button3 deletes it.\n"
-"\n"
-"     Sometimes new window detection fails.\n"
-"\n"
-"     Sometimes menu/popup detection fails.\n"
-"\n"
-"     Sometimes the contents of a menu/popup window have blacked-out regions.\n"
-"     Try -sid or -showmenus as a workaround.\n"
-"\n"
-"     If the application starts up a new application (a different process)\n"
-"     that new application will not be tracked (but, unfortunately, it may\n"
-"     cover up existing windows that are being tracked.) See cmd=add_window\n"
-"     and cmd=add_app described above.\n"

- *
- * This tool knows nothing about the RFB protocol: it simply
- * encrypts/decrypts a stream using a symmetric cipher, arc4 and aesv2,
- * (others have been added, see usage).  It could be used as a general
- * encrypted tunnel:
- *
- *   any-client <=> ultravnc_dsm_helper <--network--> ultravnc_dsm_helper(reverse mode) <=> any-server
- *
- * e.g. to connect a non-ultra-dsm-vnc viewer to a non-ultra-dsm-vnc server
- * without using SSH or SSL.
- *
- * It can also be used as a general TCP relay (no encryption.)
- *
- * It supports IPv6 and so can also be used as a IPv6 gateway.

-"   Run this command in a shell on the remote machine \"far-host\"\n"
-"   with X session you wish to view:\n"
-"\n"
-"       x11vnc -display :0\n"

-"\n"
-"       vncviewer far-host:0\n"
-"\n"
-"Once x11vnc establishes connections with the X11 server and starts listening\n"
-"as a VNC server it will print out a string: PORT=XXXX where XXXX is typically\n"
-"5900 (the default VNC server port).  One would next run something like\n"
-"this on the local machine: \"vncviewer hostname:N\" where \"hostname\" is\n"
-"the name of the machine running x11vnc and N is XXXX - 5900, i.e. usually\n"
-"\"vncviewer hostname:0\".\n"

-"By default x11vnc will not allow the screen to be shared and it will exit\n"
-"as soon as the client disconnects.  See -shared and -forever below to override\n"
-"these protections.  See the FAQ for details how to tunnel the VNC connection\n"

-"\n"
-"       vncviewer -encodings 'copyrect tight zrle hextile' localhost:0\n"

-"Likewise \"wait 100\" or \"-wait 100\" are acceptable and equivalent lines.\n"

-"either verbatim or with modifications and/or translated into another\n"
-"language.  (Hereinafter, translation is included without limitation in\n"
-"the term \"modification\".)  Each licensee is addressed as \"you\".\n"
-"\n"
-"Activities other than copying, distribution and modification are not\n"
-"covered by this License; they are outside its scope.  The act of\n"
-"running the Program is not restricted, and the output from the Program\n"
-"is covered only if its contents constitute a work based on the\n"
-"Program (independent of having been made by running the Program).\n"
-"Whether that is true depends on what the Program does.\n"
-"\n"
-"  1. You may copy and distribute verbatim copies of the Program's\n"
-"source code as you receive it, in any medium, provided that you\n"
-"conspicuously and appropriately publish on each copy an appropriate\n"
-"copyright notice and disclaimer of warranty; keep intact all the\n"
-"notices that refer to this License and to the absence of any warranty;\n"
-"and give any other recipients of the Program a copy of this License\n"
-"along with the Program.\n"
-"\n"
-"You may charge a fee for the physical act of transferring a copy, and\n"
-"you may at your option offer warranty protection in exchange for a fee.\n"
-"\n"
-"  2. You may modify your copy or copies of the Program or any portion\n"
-"of it, thus forming a work based on the Program, and copy and\n"
-"distribute such modifications or work under the terms of Section 1\n"
-"above, provided that you also meet all of these conditions:\n"
-"\n"
-"    a) You must cause the modified files to carry prominent notices\n"
-"    stating that you changed the files and the date of any change.\n"
-"\n"
-"    b) You must cause any work that you distribute or publish, that in\n"
-"    whole or in part contains or is derived from the Program or any\n"
-"    part thereof, to be licensed as a whole at no charge to all third\n"
-"    parties under the terms of this License.\n"
-"\n"
-"    c) If the modified program normally reads commands interactively\n"
-"    when run, you must cause it, when started running for such\n"
-"    interactive use in the most ordinary way, to print or display an\n"
-"    announcement including an appropriate copyright notice and a\n"
-"    notice that there is no warranty (or else, saying that you provide\n"
-"    a warranty) and that users may redistribute the program under\n"
-"    these conditions, and telling the user how to view a copy of this\n"
-"    License.  (Exception: if the Program itself is interactive but\n"
-"    does not normally print such an announcement, your work based on\n"
-"    the Program is not required to print an announcement.)\n"
-"\n"
-"These requirements apply to the modified work as a whole.  If\n"
-"identifiable sections of that work are not derived from the Program,\n"
-"and can be reasonably considered independent and separate works in\n"
-"themselves, then this License, and its terms, do not apply to those\n"
-"sections when you distribute them as separate works.  But when you\n"
-"distribute the same sections as part of a whole which is a work based\n"
-"on the Program, the distribution of the whole must be on the terms of\n"
-"this License, whose permissions for other licensees extend to the\n"
-"entire whole, and thus to each and every part regardless of who wrote it.\n"
-"\n"
-"Thus, it is not the intent of this section to claim rights or contest\n"
-"your rights to work written entirely by you; rather, the intent is to\n"
-"exercise the right to control the distribution of derivative or\n"
-"collective works based on the Program.\n"
-"\n"
-"In addition, mere aggregation of another work not based on the Program\n"
-"with the Program (or with a work based on the Program) on a volume of\n"
-"a storage or distribution medium does not bring the other work under\n"
-"the scope of this License.\n"
-"\n"
-"  3. You may copy and distribute the Program (or a work based on it,\n"
-"under Section 2) in object code or executable form under the terms of\n"
-"Sections 1 and 2 above provided that you also do one of the following:\n"
-"\n"
-"    a) Accompany it with the complete corresponding machine-readable\n"
-"    source code, which must be distributed under the terms of Sections\n"
-"    1 and 2 above on a medium customarily used for software interchange; or,\n"
-"\n"
-"    b) Accompany it with a written offer, valid for at least three\n"
-"    years, to give any third party, for a charge no more than your\n"
-"    cost of physically performing source distribution, a complete\n"
-"    machine-readable copy of the corresponding source code, to be\n"
-"    distributed under the terms of Sections 1 and 2 above on a medium\n"
-"    customarily used for software interchange; or,\n"
-"\n"
-"    c) Accompany it with the information you received as to the offer\n"
-"    to distribute corresponding source code.  (This alternative is\n"
-"    allowed only for noncommercial distribution and only if you\n"
-"    received the program in object code or executable form with such\n"
-"    an offer, in accord with Subsection b above.)\n"
-"\n"
-"The source code for a work means the preferred form of the work for\n"
-"making modifications to it.  For an executable work, complete source\n"
-"code means all the source code for all modules it contains, plus any\n"
-"associated interface definition files, plus the scripts used to\n"
-"control compilation and installation of the executable.  However, as a\n"
-"special exception, the source code distributed need not include\n"
-"anything that is normally distributed (in either source or binary\n"
-"form) with the major components (compiler, kernel, and so on) of the\n"
-"operating system on which the executable runs, unless that component\n"
-"itself accompanies the executable.\n"
-"\n"
-"If distribution of executable or object code is made by offering\n"
-"access to copy from a designated place, then offering equivalent\n"
-"access to copy the source code from the same place counts as\n"
-"distribution of the source code, even though third parties are not\n"
-"compelled to copy the source along with the object code.\n"
-"\n"
-"  4. You may not copy, modify, sublicense, or distribute the Program\n"
-"except as expressly provided under this License.  Any attempt\n"
-"otherwise to copy, modify, sublicense or distribute the Program is\n"
-"void, and will automatically terminate your rights under this License.\n"
-"However, parties who have received copies, or rights, from you under\n"
-"this License will not have their licenses terminated so long as such\n"
-"parties remain in full compliance.\n"
-"\n"
-"  5. You are not required to accept this License, since you have not\n"
-"signed it.  However, nothing else grants you permission to modify or\n"
-"distribute the Program or its derivative works.  These actions are\n"
-"prohibited by law if you do not accept this License.  Therefore, by\n"
-"modifying or distributing the Program (or any work based on the\n"
-"Program), you indicate your acceptance of this License to do so, and\n"
-"all its terms and conditions for copying, distributing or modifying\n"
-"the Program or works based on it.\n"
-"\n"
-"  6. Each time you redistribute the Program (or any work based on the\n"
-"Program), the recipient automatically receives a license from the\n"
-"original licensor to copy, distribute or modify the Program subject to\n"
-"these terms and conditions.  You may not impose any further\n"
-"restrictions on the recipients' exercise of the rights granted herein.\n"
-"You are not responsible for enforcing compliance by third parties to\n"
-"this License.\n"
-"\n"
-"  7. If, as a consequence of a court judgment or allegation of patent\n"
-"infringement or for any other reason (not limited to patent issues),\n"
-"conditions are imposed on you (whether by court order, agreement or\n"
-"otherwise) that contradict the conditions of this License, they do not\n"
-"excuse you from the conditions of this License.  If you cannot\n"
-"distribute so as to satisfy simultaneously your obligations under this\n"
-"License and any other pertinent obligations, then as a consequence you\n"
-"may not distribute the Program at all.  For example, if a patent\n"
-"license would not permit royalty-free redistribution of the Program by\n"
-"all those who receive copies directly or indirectly through you, then\n"
-"the only way you could satisfy both it and this License would be to\n"
-"refrain entirely from distribution of the Program.\n"
-"\n"
-"If any portion of this section is held invalid or unenforceable under\n"
-"any particular circumstance, the balance of the section is intended to\n"
-"apply and the section as a whole is intended to apply in other\n"
-"circumstances.\n"
-"\n"
-"It is not the purpose of this section to induce you to infringe any\n"
-"patents or other property right claims or to contest validity of any\n"
-"such claims; this section has the sole purpose of protecting the\n"
-"integrity of the free software distribution system, which is\n"
-"implemented by public license practices.  Many people have made\n"
-"generous contributions to the wide range of software distributed\n"
-"through that system in reliance on consistent application of that\n"
-"system; it is up to the author/donor to decide if he or she is willing\n"
-"to distribute software through any other system and a licensee cannot\n"
-"impose that choice.\n"
-"\n"
-"This section is intended to make thoroughly clear what is believed to\n"
-"be a consequence of the rest of this License.\n"
-"\n"
-"  8. If the distribution and/or use of the Program is restricted in\n"
-"certain countries either by patents or by copyrighted interfaces, the\n"
-"original copyright holder who places the Program under this License\n"
-"may add an explicit geographical distribution limitation excluding\n"
-"those countries, so that distribution is permitted only in or among\n"
-"countries not thus excluded.  In such case, this License incorporates\n"
-"the limitation as if written in the body of this License.\n"
-"\n"
-"  9. The Free Software Foundation may publish revised and/or new versions\n"
-"of the General Public License from time to time.  Such new versions will\n"
-"be similar in spirit to the present version, but may differ in detail to\n"
-"address new problems or concerns.\n"
-"\n"
-"Each version is given a distinguishing version number.  If the Program\n"
-"specifies a version number of this License which applies to it and \"any\n"
-"later version\", you have the option of following the terms and conditions\n"
-"either of that version or of any later version published by the Free\n"
-"Software Foundation.  If the Program does not specify a version number of\n"
-"this License, you may choose any version ever published by the Free Software\n"
-"Foundation.\n"
-"\n"
-"  10. If you wish to incorporate parts of the Program into other free\n"
-"programs whose distribution conditions are different, write to the author\n"
-"to ask for permission.  For software which is copyrighted by the Free\n"
-"Software Foundation, write to the Free Software Foundation; we sometimes\n"
-"make exceptions for this.  Our decision will be guided by the two goals\n"
-"of preserving the free status of all derivatives of our free software and\n"
-"of promoting the sharing and reuse of software generally.\n"

-                bound to them.
-mode_switch[]   indicates which keycodes have Mode_switch (AltGr)
-                bound to them.
-shift_keys[]    indicates which keycodes have Shift bound to them.
-skipkeycode[]   indicates which keycodes are to be skipped
-                for any lookups from -skip_keycodes option. 
-
-Groups and Levels, here is an example:
-                                                                  
-      ^          --------                                      
-      |      L2 | A   AE |                                      
-    shift       |        |                                      
-    level    L1 | a   ae |                                      
-                 --------                                      
-                  G1  G2                                        
-                                                                
-                  group ->                                      
-
-Traditionally this it all a key could do.  L1 vs. L2 selected via Shift
-and G1 vs. G2 selected via Mode_switch.  Up to 4 Keysyms could be bound
-to a key.  See initialize_modtweak() for an example of using that type
-of keymap from XGetKeyboardMapping().
-
-Xkb gives us up to 4 groups and 63 shift levels per key, with the
-situation being potentially different for each key.  This is complicated,
-and I don't claim to understand it all, but in the following we just think
-of ranging over the group and level indices as covering all of the cases.
-This gives us an accurate view of the keymap.  The main tricky part
-is mapping between group+level and modifier state.
-
-On current linux/XFree86 setups (Xkb is enabled by default) the
-information from XGetKeyboardMapping() (evidently the compat map)
-is incomplete and inaccurate, so we are really forced to use the
-Xkb API.
-
-xkbkeysyms[]      For a (keycode,group,level) holds the KeySym (0 for none)
-xkbstate[]        For a (keycode,group,level) holds the corresponding
-                  modifier state needed to get that KeySym
-xkbignore[]       For a (keycode,group,level) which modifiers can be
-                  ignored (the 0 bits can be ignored).
-xkbmodifiers[]    For the KeySym bound to this (keycode,group,level) store
-                  the modifier mask.

-$program:
-
-    A hack to run a stock Xorg(1) or XFree86(1) X server with the "dummy"
-    (RAM-only framebuffer) video driver such that it AVOIDS the Linux VT
-    switching, opening device files in /dev, keyboard and mouse conflicts,
-    and other problems associated with the normal use of "dummy".
-
-    In other words, it tries to make Xorg/XFree86 with the "dummy"
-    device driver act more like Xvfb(1).
-
-    The primary motivation for the Xdummy script is to provide a virtual X
-    server for x11vnc but with more features than Xvfb (or Xvnc); however
-    it could be used for other reasons (e.g. better automated testing
-    than with Xvfb.)  One nice thing is the dummy server supports RANDR
-    dynamic resizing while Xvfb does not.
-
-    So, for example, x11vnc+Xdummy terminal services are a little better
-    than x11vnc+Xvfb.
-
-    To achieve this, while running the real Xserver $program intercepts
-    system and library calls via the LD_PRELOAD method and modifies
-    the behavior to make it work correctly (e.g. avoid the VT stuff.)
-    LD_PRELOAD tricks are usually "clever hacks" and so might not work
-    in all situations or break when something changes.
-
-    WARNING: Take care in using Xdummy, although it never has it is
-    possible that it could damage hardware.  One can use the -prconf
-    option to have it print out the xorg.conf config that it would use
-    and then inspect it carefully before actually using it.
-
-    This program no longer needs to be run as root as of 12/2009.
-    However, if there are problems for certain situations (usually older
-    servers) it may perform better if run as root (use the -root option.)
-    When running as root remember the previous paragraph and that Xdummy
-    comes without any warranty.
-
-    gcc/cc and other build tools are required for this script to be able
-    to compile the LD_PRELOAD shared object.  Be sure they are installed
-    on the system.  See -install and -uninstall described below.
-
-    Your Linux distribution may not install the dummy driver by default,
-    e.g:
-
-        /usr/lib/xorg/modules/drivers/dummy_drv.so
-    
-    some have it in a package named xserver-xorg-video-dummy you that
-    need to install.
-
-Usage:
-
-	$program <${program}-args> <Xserver-args>
-
-	(actually, the arguments can be supplied in any order.)
-
-Examples:
-
-	$program -install
-
-	$program :1
-
-	$program -debug :1
-
-	$program -tmpdir ~/mytmp :1 -nolisten tcp
-
-startx example:
-
-	startx -e bash -- $program :2 -depth 16
-
-	(if startx needs to be run as root, you can su(1) to a normal
-	user in the bash shell and then launch ~/.xinitrc or ~/.xsession,
-	gnome-session, startkde, startxfce4, etc.)
-
-xdm example:
-
-	xdm -config /usr/local/dummy/xdm-config -nodaemon
-
-	where the xdm-config file has line:
-
-	     DisplayManager.servers:         /usr/local/dummy/Xservers
-
-	and /usr/local/dummy/Xservers has lines:
-
-	     :1 local /usr/local/dummy/Xdummy :1 -debug
-	     :2 local /usr/local/dummy/Xdummy :2 -debug
-
-        (-debug is optional)
-
-gdm/kdm example:
-
-	TBD.
-
-Root permission and x11vnc:
-
-	Update: as of 12/2009 this program no longer must be run as root.
-	So try it as non-root before running it as root and/or the
-	following schemes.
-
-	In some circumstances X server program may need to be run as root.
-	If so, one could run x11vnc as root with -unixpw (it switches
-	to the user that logs in) and that may be OK, some other ideas:
-
-	- add this to sudo via visudo:
-
-		ALL ALL = NOPASSWD: /usr/local/bin/Xdummy
-
-	- use this little suid wrapper:
-/* 
- * xdummy.c
- *
-   cc -o ./xdummy xdummy.c
-   sudo cp ./xdummy /usr/local/bin/xdummy
-   sudo chown root:root /usr/local/bin/xdummy
-   sudo chmod u+s /usr/local/bin/xdummy
- *

-
-
-Options:
-
-    ${program}-args:
-
-	-install	Compile the LD_PRELOAD shared object and install it
-			next to the $program script file as:
-
-			  $0.so
-
-			When that file exists it is used as the LD_PRELOAD
-			shared object without recompiling.  Otherwise,
-			each time $program is run the LD_PRELOAD shared
-			object is compiled as a file in /tmp (or -tmpdir)
-
-			If you set the environment variable
-			INTERPOSE_GETUID=1 when building, then when
-			$program is run as an ordinary user, the shared
-			object will interpose getuid() calls and pretend
-			to be root.  Otherwise it doesn't pretend to
-			be root.
-
-			You can also set the CFLAGS environment variable
-			to anything else you want on the compile cmdline.
-
-	-uninstall	Remove the file:
-
-			  $0.so
-
-			The LD_PRELOAD shared object will then be compiled
-			each time this program is run.
-
-	The X server is not started under -install, -uninstall, or -prconf.
-
-
-	:N		The DISPLAY (e.g. :15) is often the first
-			argument.  It is passed to the real X server and
-			also used by the Xdummy script as an identifier.
-
-	-geom geom1[,geom2...]	Take the geometry (e.g. 1024x768) or list
-			of geometries and insert them into the Screen
-			section of the tweaked X server config file.
-			Use this to have a different geometry than the
-			one(s) in the system config file.
-
-			The option -geometry can be used instead of -geom;
-			x11vnc calls Xdummy and Xvfb this way.
-
-	-nomodelines	When you specify -geom/-geometry, $program will
-			create Modelines for each geometry and put them
-			in the Monitor section.  If you do not want this
-			then supply -nomodelines.
-
-	-depth n	Use pixel color depth n (e.g. 8, 16, or 24). This
-			makes sure the X config file has a Screen.Display
-			subsection of this depth.  Note this option is
-			ALSO passed to the X server.
-
-	-DEPTH n	Same as -depth, except not passed to X server.
-
-	-tmpdir dir	Specify a temporary directory, owned by you and
-			only writable by you.  This is used in place of
-			/tmp/Xdummy.\$USER/..  to place the $program.so
-			shared object, tweaked config files, etc.
-
-	-nonroot	Run in non-root mode (working 12/2009, now default)
-
-	-root		Run as root (may still be needed in some
-			environments.)  Same as XDUMMY_RUN_AS_ROOT=1.
-
-	-nosudo		Do not try to use sudo(1) when re-running as root,
-			use su(1) instead.
-
-	-xserver path	Specify the path to the Xserver to use.  Default
-			is to try "Xorg" first and then "XFree86".  If
-			those are not in \$PATH, it tries these locations:
-				/usr/bin/Xorg
-				/usr/X11R6/bin/Xorg
-				/usr/X11R6/bin/XFree86
-
-	-n		Do not run the command to start the X server,
-			just show the command that $program would run.
-			The LD_PRELOAD shared object will be built,
-			if needed.  Also note any XDUMMY* environment
-			variables that need to be set.
-
-	-prconf		Print, to stdout, the tweaked Xorg/XFree86
-			config file (-config and -xf86config server
-			options, respectively.)  The Xserver is not
-			started.
-
-	-notweak	Do not tweak (modify) the Xorg/XFree86 config file
-			(system or server command line) at all.  The -geom
-			and similar config file modifications are ignored.
-
-			It is up to you to make sure it is a working
-			config file (e.g. "dummy" driver, etc.)
-			Perhaps you want to use a file based on the
-			-prconf output.
-
-	-debug		Extra debugging output.
-
-	-strace		strace(1) the Xserver process (for troubleshooting.)
-	-ltrace		ltrace(1) instead of strace (can be slow.)
-
-	-h, -help	Print out this help.
-
-
-    Xserver-args:
-
-	Most of the Xorg and XFree86 options will work and are simply
-	passed along if you supply them.  Important ones that may be
-	supplied if missing:
-
-	:N		X Display number for server to use.
-
-	vtNN		Linux virtual terminal (VT) to use (a VT is currently
-			still used, just not switched to and from.)
-
-	-config file		Driver "dummy" tweaked config file, a
-	-xf86config file	number of settings are tweaked besides Driver.
-
-	If -config/-xf86config is not given, the system one
-	(e.g. /etc/X11/xorg.conf) is used.  If the system one cannot be
-	found, a built-in one is used.	Any settings in the config file
-	that are not consistent with "dummy" mode will be overwritten
-	(unless -notweak is specified.)
-
-	Use -config xdummy-builtin to force usage of the builtin config.
-
-	If "file" is only a basename (e.g. "xorg.dummy.conf") with no /'s,
-	then no tweaking of it is done: the X server will look for that
-	basename via its normal search algorithm.  If the found file does
-	not refer to the "dummy" driver, etc, then the X server will fail.
-
-Notes:
-
-    The Xorg/XFree86 "dummy" driver is currently undocumented.  It works
-    well in this mode, but it is evidently not intended for end-users.
-    So it could be removed or broken at any time.
-
-    If the display Xserver-arg (e.g. :1) is not given, or ":" is given
-    that indicates $program should try to find a free one (based on
-    tcp ports.)
-
-    If the display virtual terminal, VT, (e.g. vt9) is not given that
-    indicates $program should try to find a free one (or guess a high one.) 
-    
-    This program is not completely secure WRT files in /tmp (but it tries
-    to a good degree.)  Better is to use the -tmpdir option to supply a
-    directory only writable by you.  Even better is to get rid of users
-    on the local machine you do not trust :-)
-
-    Set XDUMMY_SET_XV=1 to turn on debugging output for this script.

- *-----------------------------------------------------------------------
- *
- * This tool is intended for use with x11vnc.  It is a kludge to try to 
- * "block" access via the physical display while x11vnc is running.
- *
- * The expected application is that of a user who screen-locks his
- * workstation before leaving and then later unlocks it remotely via
- * x11vnc.  The user is concerned people with physical access to the
- * machine will be watching, etc.
- *
- * Of course if people have physical access to the machine there are
- * much larger potential security problems, but the idea here is to put
- * up a larger barrier than simply turning on the monitor and tapping
- * the mouse (i.e. to wake up the monitor from DPMS and then observe
- * the x11vnc activity).
- *
- * This program requires DPMS support in the video card and monitor,
- * and the DPMS extension in the X server and the corresponding
- * library with the DPMS API (libXext).
- *
- * It starts off by forcing the state to be DPMSModeOff (lowest power).
- * Then it periodically (a few times a second) checks if the system is
- * still in that state.  If it discovers it to be in another state, it
- * immediately runs, as a separate command, a screen-lock program, "xlock"
- * by default.  The environment variable XLOCK_CMD or -lock option can
- * override this default.  "xscreensaver-command" might be another choice.
- *
- * It is up to the user to make sure the screen-lock command works
- * and PATH is set up correctly, etc.  The command can do anything,
- * it doesn't have to lock the screen.  It could make the sound of a
- * dog barking, for example :-)
- *
- * The option '-grab' causes the program to additionally call
- * XGrabServer() to try to prevent physical mouse or keyboard input to get
- * to any applications on the screen.  NOTE: do NOT use, not working yet!
- * Freezes everything.
- *
- * The options: -display and -auth can be used to set the DISPLAY and
- * XAUTHORITY environment variables via the command line.
- *
- * The options -standby and -suspend change the desired DPMS level
- * to be DPMSModeStandby and DPMSModeSuspend, respectively. 
- *
- * The option '-f flagfile' indicates a flag file to watch for to cause
- * the program to clean up and exit once it exists.  No screen locking is
- * done when the file appears: it is an 'all clear' flag.  Presumably the
- * x11vnc user has relocked the screen before the flagfile is created.
- * See below for coupling this behavior with the -gone command.
- *
- * The option '-bg' causes the program to fork into the background and
- * return 0 if everything looks ok.  If there was an error up to that
- * point the return value would be 1.
- * 
- * Option '-v' prints more info out, useful for testing and debugging.
- * 
- * 
- * These options allow this sort of x11vnc usage:
- *
- * x11vnc ... -accept "blockdpy -bg -f $HOME/.bdpy" -gone "touch $HOME/.bdpy"
- *
- * (this may also work for gone: -gone "killall blockdpy")
- *
- * In the above, once a client connects this program starts up in the
- * background and monitors the DPMS level.  When the client disconnects
- * (he relocked the screen before doing so) the flag file is created and
- * so this program exits normally.  On the other hand, if the physical
- * mouse or keyboard was used during the session, this program would
- * have locked the screen as soon as it noticed the DPMS change.
- *
- * One could create shell scripts for -accept and -gone that do much
- * more sophisticated things.  This would be needed if more than one
- * client connects at a time.
- *
- * It is important to remember once this program locks the screen
- * it *exits*, so nothing will be watching the screen at that point.
- * Don't immediately unlock the screen from in x11vnc!!  Best to think
- * about what might have happened, disconnect the VNC viewer, and then
- * restart x11vnc (thereby having this monitoring program started again).
- *
- *
- * To compile on Linux or Solaris:
-
- cc -o blockdpy blockdpy.c -L /usr/X11R6/lib -L /usr/openwin/lib -lX11 -lXext
-
- * (may also need -I /usr/.../include on older machines).

-# connect_switch:
-#
-# A kludge script that sits between web clients and a mod_ssl (https)
-# enabled apache webserver.  
-#
-# If an incoming web client connection makes a proxy CONNECT request
-# it is handled directly by this script (apache is not involved).
-# Otherwise, all other connections are forwarded to the apache webserver.
-#
-# This can be useful for VNC redirection using an existing https (port
-# 443) webserver, thereby not requiring a 2nd (non-https) port open on
-# the firewall for the CONNECT requests.
-#
-# It does not seem possible (to me) to achieve this entirely within apache
-# because the CONNECT request appears to be forwarded encrypted to
-# the remote host and so the SSL dies immediately. 
-#
-# It can also be used to redirect ANY protocol, e.g. SSH, not just VNC.
-# See CONNECT_SWITCH_APPLY_VNC_OFFSET=0 to disable VNC 5900 shift.
-#
-# Note: There is no need to use this script for a non-ssl apache webserver
-# port because mod_proxy works fine for doing the switching all inside
-# apache (see ProxyRequests and AllowCONNECT parameters).
-#
-#
-# Apache configuration:
-#
-# The mod_ssl configuration is often in a file named ssl.conf.  In the
-# simplest case you change something like this:
-#
-#   From:
-#   
-#     Listen 443
-#     
-#     <VirtualHost _default_:443>
-#     ...
-#     </VirtualHost>
-#     
-#   To:
-#   
-#     Listen 127.0.0.1:443
-#     
-#     <VirtualHost _default_:443>
-#     ...
-#     </VirtualHost>
-#
-# (i.e. just change the Listen directive).
-#
-# If you have mod_ssl listening on a different internal port, you do
-# not need to specify the localhost Listen address.
-#
-# It is probably a good idea to set $listen_host below to the known
-# IP address you want the service to listen on (to avoid localhost where
-# apache is listening).

-##########################################################################
-# desktop.cgi:
-#
-# This is an example CGI script to provide multi-user web access to
-# x11vnc desktops.  The user desktop sessions run in 'Xvfb' displays
-# that are created automatically.
-#
-# This script should/must be served by an HTTPS (i.e. SSL) webserver,
-# otherwise the unix and vnc passwords would be sent over the network
-# unencrypted (see below to disable if you really want to.)
-#
-# The Java VNC Viewer applet connections are encrypted by SSL as well.
-#
-# You can use this script to provide unix users desktops available on
-# demand via any Java enabled web browser.  One could also use this for
-# a special-purpose 'single application' service running in a minimal
-# window manager.
-#
-# One example of a special-purpose application would be a scientific
-# data visualization tool running on a server where the data is housed.
-# To do this set $x11vnc_extra_opts = '-env FD_PROG=/path/to/app/launcher'
-# where the program launches your special purpose application.  A very
-# simple example:  '-env FD_PROG=/usr/bin/xclock'
-# 
-#
-# Depending on where you place this script, the user accesses the service
-# with the URL:
-#
-#     https://your.webserver.net/cgi-bin/desktop.cgi
-#
-# Then they login with their unix username and password to get their
-# own desktop session.
-#
-# If the user has an existing desktop it is connected to directly,
-# otherwise a new session is created inside an Xvfb display and then
-# connected to by VNC.
-#
-# It is possible to do port redirection to other machines running SSL
-# enabled VNC servers (see below.)  This script does not start the VNC
-# servers on the other machines, although with some extra rigging you
-# should be able to do that as well.
-#
-# You can customize the login procedure to whatever you want by modifying
-# this script, or by using ideas in this script write your own PHP,
-# (for example), script.
-#
-##########################################################################
-# Overriding default settings:
-#
-# If you want to override any settings in this script and do not
-# want to edit this script create the assignments in a file named
-# 'desktop.cgi.conf' in the same directory as desktop.cgi.  It will be
-# sourced after the defaults are set.  The format of desktop.cgi.conf
-# is simply perl statements that make the assignments.
-#
-# For example, if you put something like this in desktop.cgi.conf:
-#
-#	$x11vnc = '/usr/local/bin/x11vnc';
-#
-# that will set the path to the x11vnc binary to that location.  Look at
-# the settings below for the other variables that you can modify, for
-# example one could set $allowed_users_file.
-#
-##########################################################################
-# x11vnc:
-#
-# You need to install x11vnc or otherwise have it available.  It is
-# REQUIRED that you use x11vnc 0.9.10 or later.  It won't work with
-# earlier versions.  See below the $x11vnc parameter that you can set
-# to the full path to x11vnc.
-#
-##########################################################################
-# Xvfb:
-#
-# Note that the x11vnc -create virtual desktop service used below requires
-# that you install the 'Xvfb' program.  On debian this is currently done
-# via 'apt-get install xvfb'.
-#
-# If you are having trouble getting 'x11vnc -create' to work with this
-# script (it can be tricky), try it manually and/or see the x11vnc FAQ
-# links below.
-#
-##########################################################################
-# Apache httpd:
-#
-# You should put this script in, say, a cgi-bin directory.  Enable cgi
-# scripts in your apache (or other httpd) config.  For example, we have
-# these lines (not commented):
-#
-# In httpd.conf:
-#
-#	ScriptAlias /cgi-bin/ "/dist/apache/2.0/cgi-bin/"
-#
-#	<Directory "/dist/apache/2.0/cgi-bin">
-#	    AllowOverride None
-#	    Options None     
-#	    Order allow,deny
-#	    Allow from all 
-#	</Directory>
-#
-# and in ssl.conf:
-#
-#	<Directory "/dist/apache/2.0/cgi-bin">
-#	    SSLOptions +StdEnvVars
-#	</Directory>
-#
-# Do not be confused by the non-standard /dist/apache/2.0 apache
-# installation location that we happen to use.  Yours will be different.
-#
-# You can test that you have CGI scripts working properly with the 
-# 'test-cgi' and 'printenv' scripts apache provides.
-#
-# Copy this file (desktop.cgi) to /dist/apache/2.0/cgi-bin and then run
-# 'chmod 755 ...' on it to make it executable.
-#
-##########################################################################
-# Applet Jar files served by apache:
-#
-# You will *also* need to copy the x11vnc classes/ssl/UltraViewerSSL.jar
-# file to the httpd DocumentRoot to be accessible by: /UltraViewerSSL.jar
-# in a URL (or change $applet_jar below or the html in $applet_html if
-# you want to use a different location.)
-#
-# This location is relative to the apache DocumentRoot 'htdocs' directory.
-# For our (non-standard location installation) that meant we copied the
-# file to:
-#
-#    /dist/apache/2.0/htdocs/UltraViewerSSL.jar
-#
-# (your DocumentRoot directory will be different.) 
-#
-# The VncViewer.jar (tightvnc) will also work, but you need to change
-# the $applet_jar below.  You can get these jar files from the x11vnc
-# tarball from:
-#
-#    http://www.karlrunge.com/x11vnc/#downloading
-#
-# This script requires x11vnc 0.9.10 or later.
-#
-# Note that the usage mode for this script is a different from regular
-# 'x11vnc -http ...' usage where x11vnc acts as a mini web server and
-# serves its own applet jars.  We don't use that mode for this script.
-# Apache (httpd) serves the jars.
-#
-#
-##########################################################################
-# Notes and Information:
-#
-# Each x11vnc server created for a user login will listen on its own port
-# (see below for port selection schemes.)  Your firewall must let in *ALL*
-# of these ports (e.g. a port range, see below for the syntax.)
-#
-# It is also possible, although not as reliable, to do all of this through
-# a single port, see the fixed port scheme $find_free_port = 'fixed:5910'
-# below.  This single port mode must be different from apache's port
-# (usually 443 for https) and must also be allowed in by your firewall.
-#
-# Note: The fixed port scheme is DISABLED by default.
-#
-# It is also possible to have this script act as a vnc redirector to SSL
-# enabled VNC servers running on *other* machines inside your firewall
-# (presumably the users' desktops) See the $enable_port_redirection
-# setting below.  The user provides 'username@host:port' instead of just
-# 'username' when she logs in.  This script doesn't start VNC servers
-# on those other machines, the servers must be running there already.
-# (If you want this script to start them you will need to add it
-# yourself.)  It is possible to provide a host:port allow list to limit
-# which internal machines and ports can be redirected to.  This is the
-# $port_redirection_allowed_hosts parameter.
-#
-# Note: The vnc redirector scheme is DISABLED by default.
-#
-# Note there are *two* SSL certificates involved that the user may be
-# asked to inspect: apache's SSL cert and x11vnc's SSL cert.  This may
-# confuse naive users.  You may want to use the same cert for both.
-#
-# This script provides one example on how to provide the service.  You can
-# customize it to meet your needs, e.g. switch to php, newer cgi modules,
-# different authentication, SQL database for user authentication, etc,
-# etc.  If you plan to use it in production, please examine all security
-# aspects of it carefully; read the comments in the script for more info.

-                          59 Temple Place - Suite 330, Boston, MA
-                          02111-1307, USA.
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
-			    Preamble
-
-  The licenses for most software are designed to take away your
-freedom to share and change it.  By contrast, the GNU General Public
-License is intended to guarantee your freedom to share and change free
-software--to make sure the software is free for all its users.  This
-General Public License applies to most of the Free Software
-Foundation's software and to any other program whose authors commit to
-using it.  (Some other Free Software Foundation software is covered by
-the GNU Library General Public License instead.)  You can apply it to
-your programs, too.
-
-  When we speak of free software, we are referring to freedom, not
-price.  Our General Public Licenses are designed to make sure that you
-have the freedom to distribute copies of free software (and charge for
-this service if you wish), that you receive source code or can get it
-if you want it, that you can change the software or use pieces of it
-in new free programs; and that you know you can do these things.
-
-  To protect your rights, we need to make restrictions that forbid
-anyone to deny you these rights or to ask you to surrender the rights.
-These restrictions translate to certain responsibilities for you if you
-distribute copies of the software, or if you modify it.
-
-  For example, if you distribute copies of such a program, whether
-gratis or for a fee, you must give the recipients all the rights that
-you have.  You must make sure that they, too, receive or can get the
-source code.  And you must show them these terms so they know their
-rights.
-
-  We protect your rights with two steps: (1) copyright the software, and
-(2) offer you this license which gives you legal permission to copy,
-distribute and/or modify the software.
-
-  Also, for each author's protection and ours, we want to make certain
-that everyone understands that there is no warranty for this free
-software.  If the software is modified by someone else and passed on, we
-want its recipients to know that what they have is not the original, so
-that any problems introduced by others will not reflect on the original
-authors' reputations.
-
-  Finally, any free program is threatened constantly by software
-patents.  We wish to avoid the danger that redistributors of a free
-program will individually obtain patent licenses, in effect making the
-program proprietary.  To prevent this, we have made it clear that any
-patent must be licensed for everyone's free use or not licensed at all.
-
-  The precise terms and conditions for copying, distribution and
-modification follow.
-
-		    GNU GENERAL PUBLIC LICENSE
-   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-
-  0. This License applies to any program or other work which contains
-a notice placed by the copyright holder saying it may be distributed
-under the terms of this General Public License.  The "Program", below,
-refers to any such program or work, and a "work based on the Program"
-means either the Program or any derivative work under copyright law:
-that is to say, a work containing the Program or a portion of it,
-either verbatim or with modifications and/or translated into another
-language.  (Hereinafter, translation is included without limitation in
-the term "modification".)  Each licensee is addressed as "you".
-
-Activities other than copying, distribution and modification are not
-covered by this License; they are outside its scope.  The act of
-running the Program is not restricted, and the output from the Program
-is covered only if its contents constitute a work based on the
-Program (independent of having been made by running the Program).
-Whether that is true depends on what the Program does.
-
-  1. You may copy and distribute verbatim copies of the Program's
-source code as you receive it, in any medium, provided that you
-conspicuously and appropriately publish on each copy an appropriate
-copyright notice and disclaimer of warranty; keep intact all the
-notices that refer to this License and to the absence of any warranty;
-and give any other recipients of the Program a copy of this License
-along with the Program.
-
-You may charge a fee for the physical act of transferring a copy, and
-you may at your option offer warranty protection in exchange for a fee.
-
-  2. You may modify your copy or copies of the Program or any portion
-of it, thus forming a work based on the Program, and copy and
-distribute such modifications or work under the terms of Section 1
-above, provided that you also meet all of these conditions:
-
-    a) You must cause the modified files to carry prominent notices
-    stating that you changed the files and the date of any change.
-
-    b) You must cause any work that you distribute or publish, that in
-    whole or in part contains or is derived from the Program or any
-    part thereof, to be licensed as a whole at no charge to all third
-    parties under the terms of this License.
-
-    c) If the modified program normally reads commands interactively
-    when run, you must cause it, when started running for such
-    interactive use in the most ordinary way, to print or display an
-    announcement including an appropriate copyright notice and a
-    notice that there is no warranty (or else, saying that you provide
-    a warranty) and that users may redistribute the program under
-    these conditions, and telling the user how to view a copy of this
-    License.  (Exception: if the Program itself is interactive but
-    does not normally print such an announcement, your work based on
-    the Program is not required to print an announcement.)
-
-These requirements apply to the modified work as a whole.  If
-identifiable sections of that work are not derived from the Program,
-and can be reasonably considered independent and separate works in
-themselves, then this License, and its terms, do not apply to those
-sections when you distribute them as separate works.  But when you
-distribute the same sections as part of a whole which is a work based
-on the Program, the distribution of the whole must be on the terms of
-this License, whose permissions for other licensees extend to the
-entire whole, and thus to each and every part regardless of who wrote it.
-
-Thus, it is not the intent of this section to claim rights or contest
-your rights to work written entirely by you; rather, the intent is to
-exercise the right to control the distribution of derivative or
-collective works based on the Program.
-
-In addition, mere aggregation of another work not based on the Program
-with the Program (or with a work based on the Program) on a volume of
-a storage or distribution medium does not bring the other work under
-the scope of this License.
-
-  3. You may copy and distribute the Program (or a work based on it,
-under Section 2) in object code or executable form under the terms of
-Sections 1 and 2 above provided that you also do one of the following:
-
-    a) Accompany it with the complete corresponding machine-readable
-    source code, which must be distributed under the terms of Sections
-    1 and 2 above on a medium customarily used for software interchange; or,
-
-    b) Accompany it with a written offer, valid for at least three
-    years, to give any third party, for a charge no more than your
-    cost of physically performing source distribution, a complete
-    machine-readable copy of the corresponding source code, to be
-    distributed under the terms of Sections 1 and 2 above on a medium
-    customarily used for software interchange; or,
-
-    c) Accompany it with the information you received as to the offer
-    to distribute corresponding source code.  (This alternative is
-    allowed only for noncommercial distribution and only if you
-    received the program in object code or executable form with such
-    an offer, in accord with Subsection b above.)
-
-The source code for a work means the preferred form of the work for
-making modifications to it.  For an executable work, complete source
-code means all the source code for all modules it contains, plus any
-associated interface definition files, plus the scripts used to
-control compilation and installation of the executable.  However, as a
-special exception, the source code distributed need not include
-anything that is normally distributed (in either source or binary
-form) with the major components (compiler, kernel, and so on) of the
-operating system on which the executable runs, unless that component
-itself accompanies the executable.
-
-If distribution of executable or object code is made by offering
-access to copy from a designated place, then offering equivalent
-access to copy the source code from the same place counts as
-distribution of the source code, even though third parties are not
-compelled to copy the source along with the object code.
-
-  4. You may not copy, modify, sublicense, or distribute the Program
-except as expressly provided under this License.  Any attempt
-otherwise to copy, modify, sublicense or distribute the Program is
-void, and will automatically terminate your rights under this License.
-However, parties who have received copies, or rights, from you under
-this License will not have their licenses terminated so long as such
-parties remain in full compliance.
-
-  5. You are not required to accept this License, since you have not
-signed it.  However, nothing else grants you permission to modify or
-distribute the Program or its derivative works.  These actions are
-prohibited by law if you do not accept this License.  Therefore, by
-modifying or distributing the Program (or any work based on the
-Program), you indicate your acceptance of this License to do so, and
-all its terms and conditions for copying, distributing or modifying
-the Program or works based on it.
-
-  6. Each time you redistribute the Program (or any work based on the
-Program), the recipient automatically receives a license from the
-original licensor to copy, distribute or modify the Program subject to
-these terms and conditions.  You may not impose any further
-restrictions on the recipients' exercise of the rights granted herein.
-You are not responsible for enforcing compliance by third parties to
-this License.
-
-  7. If, as a consequence of a court judgment or allegation of patent
-infringement or for any other reason (not limited to patent issues),
-conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License.  If you cannot
-distribute so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you
-may not distribute the Program at all.  For example, if a patent
-license would not permit royalty-free redistribution of the Program by
-all those who receive copies directly or indirectly through you, then
-the only way you could satisfy both it and this License would be to
-refrain entirely from distribution of the Program.
-
-If any portion of this section is held invalid or unenforceable under
-any particular circumstance, the balance of the section is intended to
-apply and the section as a whole is intended to apply in other
-circumstances.
-
-It is not the purpose of this section to induce you to infringe any
-patents or other property right claims or to contest validity of any
-such claims; this section has the sole purpose of protecting the
-integrity of the free software distribution system, which is
-implemented by public license practices.  Many people have made
-generous contributions to the wide range of software distributed
-through that system in reliance on consistent application of that
-system; it is up to the author/donor to decide if he or she is willing
-to distribute software through any other system and a licensee cannot
-impose that choice.
-
-This section is intended to make thoroughly clear what is believed to
-be a consequence of the rest of this License.
-
-  8. If the distribution and/or use of the Program is restricted in
-certain countries either by patents or by copyrighted interfaces, the
-original copyright holder who places the Program under this License
-may add an explicit geographical distribution limitation excluding
-those countries, so that distribution is permitted only in or among
-countries not thus excluded.  In such case, this License incorporates
-the limitation as if written in the body of this License.
-
-  9. The Free Software Foundation may publish revised and/or new versions
-of the General Public License from time to time.  Such new versions will
-be similar in spirit to the present version, but may differ in detail to
-address new problems or concerns.
-
-Each version is given a distinguishing version number.  If the Program
-specifies a version number of this License which applies to it and "any
-later version", you have the option of following the terms and conditions
-either of that version or of any later version published by the Free
-Software Foundation.  If the Program does not specify a version number of
-this License, you may choose any version ever published by the Free Software
-Foundation.
-
-  10. If you wish to incorporate parts of the Program into other free
-programs whose distribution conditions are different, write to the author
-to ask for permission.  For software which is copyrighted by the Free
-Software Foundation, write to the Free Software Foundation; we sometimes
-make exceptions for this.  Our decision will be guided by the two goals
-of preserving the free status of all derivatives of our free software and
-of promoting the sharing and reuse of software generally.
-
-			    NO WARRANTY
-
-  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
-FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
-OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
-PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
-OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
-MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
-TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
-PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
-REPAIR OR CORRECTION.
-
-  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
-WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
-REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
-INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
-OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
-TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
-YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
-PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
-POSSIBILITY OF SUCH DAMAGES.
-
-		     END OF TERMS AND CONDITIONS
-
-	Appendix: How to Apply These Terms to Your New Programs
-
-  If you develop a new program, and you want it to be of the greatest
-possible use to the public, the best way to achieve this is to make it
-free software which everyone can redistribute and change under these terms.
-
-  To do so, attach the following notices to the program.  It is safest
-to attach them to the start of each source file to most effectively
-convey the exclusion of warranty; and each file should have at least
-the "copyright" line and a pointer to where the full notice is found.
-
-    <one line to give the program's name and a brief idea of what it does.>
-    Copyright (C) 19yy  <name of author>
-
-    This program is free software; you can redistribute it and/or modify
-    it under the terms of the GNU General Public License as published by
-    the Free Software Foundation; either version 2 of the License, or
-    (at your option) any later version.
-
-    This program is distributed in the hope that it will be useful,
-    but WITHOUT ANY WARRANTY; without even the implied warranty of
-    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
-    GNU General Public License for more details.
-
-    You should have received a copy of the GNU General Public License
-    along with this program; if not, write to the Free Software
-    Foundation, Inc., 59 Temple Place - Suite 330, Boston, MA 02111-1307, USA.
-
-Also add information on how to contact you by electronic and paper mail.
-
-If the program is interactive, make it output a short notice like this
-when it starts in an interactive mode:
-
-    Gnomovision version 69, Copyright (C) 19yy name of author
-    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
-    This is free software, and you are welcome to redistribute it
-    under certain conditions; type `show c' for details.
-
-The hypothetical commands `show w' and `show c' should show the appropriate
-parts of the General Public License.  Of course, the commands you use may
-be called something other than `show w' and `show c'; they could even be
-mouse-clicks or menu items--whatever suits your program.
-
-You should also get your employer (if you work as a programmer) or your
-school, if any, to sign a "copyright disclaimer" for the program, if
-necessary.  Here is a sample; alter the names:
-
-  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
-  `Gnomovision' (which makes passes at compilers) written by James Hacker.
-
-  <signature of Ty Coon>, 1 April 1989
-  Ty Coon, President of Vice
-
-This General Public License does not permit incorporating your program into
-proprietary programs.  If your program is a subroutine library, you may
-consider it more useful to permit linking proprietary applications with the
-library.  If this is what you want to do, use the GNU Library General
-Public License instead of this License.

-=============================================================================
-
-This bundle contains a convenient collection of enhanced TightVNC
-viewers and stunnel binaries for different flavors of Unix and wrapper
-scripts and a GUI front-end to glue them together.  Automatic SSL and
-SSH encryption tunnelling is provided.
-
-A Windows SSL wrapper for the bundled TightVNC binary and other utilities
-are provided.  (Launch ssvnc.exe in the Windows subdirectory).
-
-The short name of the project is "ssvnc" for SSL/SSH VNC Viewer.
-
-It is a self-contained bundle, you could carry it around on, say,
-a USB memory stick for secure VNC viewing from almost any machine,
-Unix, Mac, or Windows.
-
-Features:
---------
-
-The enhanced TightVNC viewer features are:
-
-	- SSL support for connections using the bundled stunnel program.
-
-	- Automatic SSH connections from the GUI (ssh must already be
-	  installed on Unix; bundled plink is used on Windows)
-
-	- Ability to Save and Load VNC profiles for different hosts.
-
-	- You can also use your own VNC Viewer, e.g. UltraVNC or RealVNC,
-	  with the front-end GUI or scripts if you like.
-
-	- Create or Import SSL Certificates and Private Keys.
-
-	- Reverse (viewer listening) VNC connections via SSL and SSH.
-
-	- VeNCrypt SSL/TLS VNC encryption support (used by VeNCrypt,
-	  QEMU, ggi, libvirt/virt-manager/xen, vinagre/gvncviewer/gtk-vnc)
-
-	- ANONTLS SSL/TLS VNC encryption support (used by Vino)
-
-	- VeNCrypt and ANONTLS are also enabled for any 3rd party VNC
-	  Viewer (e.g. RealVNC, TightVNC, UltraVNC ...) on Unix, MacOSX,
-	  and Windows via the provided SSVNC VeNCrypt Viewer Bridge tool
-	  (use 'Change VNC Viewer' to select the one you want.)
-
-	- Support for Web Proxies, SOCKS Proxies, and the UltraVNC
-	  repeater proxy (e.g. repeater://host:port+ID:1234). Multiple
-	  proxies may be chained together (3 max).
-
-	- Support for SSH Gateway connections and non-standard SSH ports.
-
-	- Automatic Service tunnelling via SSH for CUPS and SMB Printing,
-	  ESD/ARTSD Audio, and SMB (Windows/Samba) filesystem mounting.
-
-	- Sets up any additional SSH port redirections that you want.
-
-	- Zeroconf (aka Bonjour) is used on Unix and Mac OS X to find
-	  VNC servers on your local network if the avahi-browse or dns-sd
-	  program is available and in your PATH.
-
-        - Port Knocking for "closed port" SSH/SSL connections.  In addition
-          to a simple fixed port sequence and one-time-pad implementation,
-          a hook is also provided to run any port knocking client before a
-          connecting.
-
-	- Support for native MacOS X usage with bundled Chicken of the
-	  VNC viewer (the Unix X11 viewer is also provided for MacOS X,
-	  and is better IMHO).
-
-	- Dynamic VNC Server Port determination and redirection (using
-	  ssh's builtin SOCKS proxy, -D) for servers like x11vnc that
-	  print out PORT= at startup.
-
-        - Unix Username and Password entry for use with "x11vnc -unixpw"
-	  type login dialogs.
-
-	- Simplified mode launched by command "sshvnc" that is SSH Only.
-
-	- Simplified mode launched by command "tsvnc" that provides a VNC
-	  "Terminal Services" mode (uses x11vnc on the remote side).
-
-
-	(the following features only apply to the bundled Unix tightvnc viewer
-        including MacOS X)
-
-	- rfbNewFBSize VNC support (screen resizing)
-
-	- Client-side Scaling of the Viewer.
-
-	- ZRLE VNC encoding support (RealVNC's encoding)
-
-	- Support for the ZYWRLE encoding, a wavelet based extension to
-	  ZRLE to improve compression of motion video and photo regions.
-
-	- TurboVNC support (VirtualGL's modified TightVNC encoding;
-	  requires TurboJPEG library)
-
-        - Pipelined Updates of the framebuffer as in TurboVNC (asks for
-          the next update before the current one has finished downloading;
-          this gives some speedup on high latency connections.)
-
-	- Cursor alphablending with x11vnc at 32bpp (-alpha option)
-
-	- Option "-unixpw ..." for use with "x11vnc -unixpw" login dialogs.
-
-	- Support for UltraVNC extensions: Single Window, Disable
-	  Server-side Input, 1/n Server side scaling, Text Chat (shell
-	  terminal UI). Both UltraVNC and x11vnc servers support these
-	  extensions
-
-	- UltraVNC File Transfer via an auxiliary Java helper program
-	  (java must be in $PATH). Note that the x11vnc server supports
-	  UltraVNC file transfer.
-
-	- Connection support for the UltraVNC repeater proxy (-repeater
-	  option).
-
-	- Support for UltraVNC Single Click operation. (both unencrypted:
-	  SC I, and SSL encrypted: SC III)
-
-        - Support for UltraVNC DSM Encryption Plugin mode. (ARC4 and
-          AESV2, MSRC4, and SecureVNC)
-
-        - Support for UltraVNC MS-Logon authentication (NOTE: the
-          UltraVNC MS-Logon key exchange implementation is very weak; an
-          eavesdropper on the network can recover your Windows password
-          easily in a few seconds; you need to use an additional encrypted
-          tunnel with MS-Logon.)
-
-        - Support for symmetric encryption (including blowfish and 3des
-          ciphers) to Non-UltraVNC Servers. Any server using the same
-          encryption method will work, e.g.:  x11vnc -enc blowfish:./my.key
-
-	- Instead of hostname:display one can also supply "exec=command
-	  args..." to connect the viewer to the stdio of an external command
-	  (e.g. stunnel or socat) rather than using a TCP/IP socket. Unix
-	  domain sockets, e.g. /path/to/unix/socket, and a previously
-	  opened file descriptor fd=0, work too.
-
-        - Local Port Protections for STUNNEL and SSH: avoid having for
-          long periods of time a listening port on the the local (VNC
-          viewer) side that redirects to the remote side.
-
-	- Reverse (viewer listening) VNC connections can show a
-	  Popup dialog asking whether to accept the connection or not
-	  (-acceptpopup.) The extra info provided by UltraVNC Single Click
-	  reverse connections is also supported (-acceptpopupsc)
-
-	- Extremely low color modes: 64 and 8 colors in 8bpp
-	  (-use64/-bgr222, -use8/-bgr111)
-
-	- Medium color mode: 16bpp mode even for 32bpp Viewer display
-	  (-16bpp/-bgr565)
-
-	- x11vnc's client-side caching -ncache method cropping option
-	  (-ycrop n). This will "hide" the large pixel buffer cache
-	  below the actual display. Set to actual height or use -1 for
-	  autodetection (tall screens are autodetected by default).
-
-        - Escape Keys: enable a set of modifier keys so when they
-          are all pressed down you can invoke Popup menu actions via
-          keystrokes. I.e., a set of 'Hot Keys'. One can also pan (move)
-          the desktop inside the viewport via Arrow keys or a mouse drag.
-
-	- Scrollbar width setting: -sbwidth n, the default is very thin,
-	  2 pixels, for less distracting -ycrop usage.
-
-	- Selection text sending and receiving can be fine-tuned with the
-	  -sendclipboard, -sendalways, and -recvtext options.
-
-	- TightVNC compression and quality levels are automatically set
-	  based on observed network latency (n.b. not bandwidth.)
-
-	- Improvements to the Popup menu, all of these can now be changed
-	  dynamically via the menu: ViewOnly, Toggle Bell, CursorShape
-	  updates, X11 Cursor, Cursor Alphablending, Toggle Tight/ZRLE,
-	  Toggle JPEG, FullColor/16bpp/8bpp (256/64/8 colors), Greyscale
-	  for low color modes, Scaling the Viewer resolution, Escape Keys,
-	  Pipeline Updates, and others, including UltraVNC extensions.
-
-	- Maintains its own BackingStore if the X server does not
-
-	- The default for localhost:0 connections is not raw encoding
-	  (local machine). Default assumes you are using SSH tunnel. Use
-	  -rawlocal to revert.
-
-	- XGrabServer support for fullscreen mode, for old window managers
-	  (-grab/-graball option).
-
-	- Fix for Popup menu positioning for old window managers
-	  (-popupfix option).
-
-	- Run vncviewer -help for all options.

-The list of software bundled in the archive files:
-
-        TightVNC Viewer           (windows, unix, macosx)
-        Chicken of the VNC Viewer (macosx)
-        Stunnel                   (windows, unix, macosx)
-        Putty/Plink/Pageant       (windows)
-        OpenSSL                   (windows)
-        esound                    (windows)
-
-These are all self-contained in the bundle directory: they will not be
-installed on your system.  Just un-zip or un-tar the file you downloaded
-and run it straight from its directory.
-
-
-Quick Start:
------------
-
-Unix and Mac OS X:
-
-    Inside a Terminal do something like the following.
-
-    Unpack the archive:
-
-        % gzip -dc ssvnc-1.0.28.tar.gz | tar xvf -
-
-    Run the GUI:
-
-        % ./ssvnc/Unix/ssvnc               (for Unix)
-
-        % ./ssvnc/MacOSX/ssvnc             (for Mac OS X)
-
-    The smaller file "ssvnc_no_windows-1.0.28.tar.gz"
-    could have been used as well.
-
-    On MacOSX you could also click on the SSVNC app icon in the Finder.
-
-    On MacOSX if you don't like the Chicken of the VNC (e.g. no local
-    cursors, no screen size rescaling, and no password prompting), and you
-    have the XDarwin X server installed, you can set DISPLAY before starting
-    ssvnc (or type DISPLAY=... in Host:Disp and hit Return).  Then our
-    enhanced TightVNC viewer will be used instead of COTVNC.
-    Update: there is now a 'Use X11 vncviewer on MacOSX' under Options ...
-
-
-    If you want a SSH-only tool (without the distractions of SSL) run
-    the command:
-
-                sshvnc
-
-    instead of "ssvnc".  Or click "SSH-Only Mode" under Options.
-    Control-h will toggle between the two modes.
-
-		
-    If you want a simple VNC Terminal Services only mode (requires x11vnc
-    on the remote server) run the command:
-
-                tsvnc
-
-    instead of "ssvnc".  Or click "Terminal Services" under Options.
-    Control-t will toggle between the two modes.
-
-    "tsvnc profile-name" and "tsvnc user@hostname" work too.

-
-Unix/MacOSX Install:
-
-    There is no standard install for the bundles, but you can make
-    symlinks like so:
-
-	cd /a/directory/in/PATH
-	ln -s /path/to/ssvnc/bin/{s,t}* .
-
-    Or put /path/to/ssvnc/bin, /path/to/ssvnc/Unix, or /path/to/ssvnc/MacOSX
-    in your PATH.
-
-    For the conventional source tarball it will compile and install, e.g.:
-
-       gzip -dc ssvnc-1.0.28.src.tar.gz | tar xvf -
-       cd ssvnc-1.0.28
-       make config
-       make all
-       make PREFIX=/my/install/dir install
-
-    then have /my/install/dir/bin in your PATH.
-
-
-Windows:
-
-    Unzip, using WinZip or a similar utility, the zip file:
-
-        ssvnc-1.0.28.zip
-
-    Run the GUI, e.g.:
-
-	Start -> Run -> Browse
-
-    and then navigate to
-
-        .../ssvnc/Windows/ssvnc.exe
-
-    select Open, and then OK to launch it.
-
-    The smaller file "ssvnc_windows_only-1.0.28.zip"
-    could have been used as well.
-
-    You can make a Windows shortcut to this program if you want to.
-
-    See the Windows/README.txt for more info.
-
-
-    If you want a SSH-only tool (without the distractions of SSL) run
-    the command:
-
-                sshvnc.bat
-
-    Or click "SSH-Only Mode" under Options.
-
-
-    If you want a simple VNC Terminal Services only mode (requires x11vnc
-    on the remote server) run the command:
-
-                tsvnc.bat
-
-    Or click "Terminal Services" under Options.  Control-t will toggle
-    between the two modes.  "tsvnc profile-name" and "tsvnc user@hostname"
-    work too.
-
-
-
-Important Note for Windows Vista: One user reports that on Windows Vista
-if you move or extract the "ssvnc" folder down to the "Program Files"
-folder you will be prompted to do this as the Administrator. But then
-when you start up ssvnc, as a regular user, it cannot create files in
-that folder and so it fails to run properly. We recommend to not copy
-or extract the "ssvnc" folder into "Program Files". Rather, extract
-it to somewhere you have write permission (e.g. C:\ or your User dir)
-and create a Shortcut to ssvnc.exe on the desktop.
-
-If you must put a launcher file down in "Program Files", perhaps an
-"ssvnc.bat" that looks like this:
-
-C:
-cd \ssvnc\Windows
-ssvnc.exe
-
-
-SSH-ONLY Mode:
---------------
-
-If you don't care for SSL and the distractions it provides in the GUI,
-run "sshvnc" (unix/macosx) or "sshvnc.bat" (windows) to run an SSH only
-version of the GUI.
-
-Terminal Services Mode
-----------------------
-
-There is an even simpler mode that uses x11vnc on the remote side for the
-session finding and management.  Run "tsvnc" (unix/macosx) or "tsvnc.bat"
-(windows) to run the Terminal Services version of the GUI.
-
-
-Bundle Info:
-------------
-
-The bundle files unpack a directory/folder named: ssvnc
-
-It contains these programs to launch the GUI:
-
-        Windows/ssvnc.exe        for Windows
-        MacOSX/ssvnc             for Mac OS X
-        Unix/ssvnc               for Unix
-
-(the Mac OS X and Unix launchers are simply links to the bin directory).
-
-
-Your bundle file should have included binaries for many OS's: Linux,
-Solaris, FreeBSD, etc.  Unpack your archive and see the subdirectories of
-
-	./bin
-
-for the ones that were shipped in this project, e.g. ./bin/Linux.i686
-Run "uname -sm" to see your OS+arch combination (n.b. all Linux x86 are
-mapped to Linux.i686).   (See the ./bin/ssvnc_cmd -h output for how to
-override platform autodection via the UNAME env. var).
-
-
-Memory Stick Usage:
--------------------
-
-If you create a directory named "Home" in that toplevel ssvnc directory
-then that will be used as the base for storing VNC profiles and
-certificates.  Also, for convenience, if you first run the command with
-"." as an argument (e.g. "ssvnc .") it will automatically create that
-"Home" directory for you.  This is handy if you want to place SSVNC
-on a USB flash drive that you carry around for mobile use and you want
-the profiles you create to stay with the drive (otherwise you'd have to
-browse to the drive directory each time you load or save).
-
-One user on Windows created a BAT file to launch SSVNC and needed to
-do this to get the Home directory correct:
-
-cd \ssvnc\Windows
-start \ssvnc\Windows\ssvnc.exe
-
-(an optional profile name can be supplied to the ssvnc.exe line)
-
-WARNING: if you use ssvnc from an "Internet Cafe", i.e.  an untrusted
-computer, an intruder may be capturing keystrokes etc.
-
-
-External Dependencies:
-----------------------
-
-On Windows everything is included.  Let us know if you find otherwise.
-
-On Unix depending on what you do you need these programs installed:
-	
-	- basic unix utilities (sh, ls, cat, awk, sed, etc..)
-	- tcl/tk (wish interpreter)
-	- xterm
-	- perl
-	- ssh
-	- openssl
-
-    Lesser used ones: netcat, esd/artsd, smbclient, smbmount, cups
-	
-On Mac OS X depending on what you do you need these programs installed:
-	
-	- basic unix utilities (sh, ls, cat, awk, sed, etc..)
-	- tcl/tk (wish interpreter)
-	- Terminal
-	- perl
-	- ssh
-	- openssl
-
-    Lesser used ones: netcat, smbclient, cups
-
-Most Mac OS X and Unix OS come with the main components installed. 
-	
-See the README.src for a more detailed description of dependencies.
-
-
-TurboVNC Support:
-----------------
-
-TurboVNC is supported in an experimental way.  To it build via the
-build.unix script described in the next section, do something like:
-
-	env TURBOVNC='-L/DIR -Xlinker --rpath=/DIR -lturbojpeg' ./build.unix
-
-where you replace /DIR with the directory where the libturbojpeg.so
-(http://sourceforge.net/project/showfiles.php?group_id=117509&package_id=166100)
-is installed.
-
-You may not need to set rpath if libturbojpeg.so is installed in a
-standard location or you use LD_LIBRARY_PATH to point to it.
-
-See the turbovnc/README in the vnc_unixsrc/vncviewer directory for
-more info.  You can find it in the ssvnc source tarball and also
-in:
-
-	src/zips/vnc_unixsrc_vncviewer.patched.tar
-
-More TurboVNC features will be enabled in the future.
-
-
-If you need to Build:
---------------------
-
-If your OS/arch is not included or the provided binary has the wrong
-library dependencies, etc. the script "build.unix" may be able to
-successfully build on for you and deposit the binaries down in ./bin/...
-using the included source code.  It is a hack but usually works.
-
-You MUST run the build.unix script from this directory (that this toplevel
-README is in, i.e "ssvnc") and like this:
-
-	./build.unix
-
-To use custom locations for libraries see the LDFLAGS_OS and CPPFLAGS_OS
-description at the top of the build.unix script.
-
-You can set these env. vars to customize the build:
-
-	SSVNC_BUILD_NO_STATIC=1        do not try to statically link libs
-	SSVNC_BUILD_FORCE_OVERWRITE=1  do not prompt about existing binaries
-	SSVNC_BUILD_SKIP_VIEWER=1      do not build vncviewer
-	SSVNC_BUILD_SKIP_STUNNEL=1     do not build stunnel
-	SSVNC_BUILD_ULTRAFTP=1         only build the file xfer helper jar
-
-here is an example to build only the vncviewer and with normal library
-linking (and in a more or less automated way):
-
- env SSVNC_BUILD_NO_STATIC=1 SSVNC_BUILD_FORCE_OVERWRITE=1 SSVNC_BUILD_SKIP_STUNNEL=1 ./build.unix
-
-Feel free to ask us if you need help running ./build.unix
-
-
-Convential Build:
-
-A more conventional source tarball is provided in ssvnc-x.y.z.src.tar.gz.
-It uses a more or less familiar 'make config; make all; make PREFIX=path install'
-method.  It does not include stunnel, so that must be installed on the
-system separately.
-
-
-The programs:
-------------
-
-Unpack your archive, and you will see "bin", "Windows", "src" directories
-and other files.  The command line wrapper scripts: 
-
-	./bin/ssvnc_cmd
-	./bin/tightvncviewer
-
-are the main programs that are run and will try to autodetect your OS+arch
-combination and if binaries are present for it automatically use them.
-(if not found try the running the build.unix script).
-
-If you prefer a GUI to prompt for parameters and then start ssvnc_cmd
-you can run this instead:
-
-	./bin/ssvnc       
-
-this is the same GUI that is run on Windows (the ssvnc.exe).
-There are also:
-
-	./bin/sshvnc	(SSH-Only)
-	./bin/tsvnc	(Terminal Services Mode)
-
-For convenience, you can make symlinks from a directory in your PATH to
-any of the 3 programs above you wish to run.  That is all you usually
-need to do for it to pick up all of the binaries, utils, etc. E.g.
-assuming $HOME/bin is in your $PATH:
-
-	cd $HOME/bin
-	ln -s /path/to/ssvnc/bin/{s,t}* .
-
-(note the "." at the end). The above commands is basically the way to
-"install" this on Unix or MacOS X.
-
-Also links to the GUI launcher script are provided in:
-
-	MacOSX/ssvnc
-	Unix/ssvnc
-
-and sshvnc and tsvnc.  You could also put the Unix or MacOSX directory
-in your PATH.
-
-
-On Windows unpack your archive and run:
-
-	Windows/ssvnc.exe
-
-
-Examples:
---------
-
-The following assume you are in the toplevel directory of the
-archive you unpacked.
-
-Use enhanced TightVNC unix viewer to connect to x11vnc via SSL:
-
-	./bin/ssvnc_cmd   far-away.east:0
-
-	./bin/tightvncviewer -ssl  far-away.east:0   (same)
-
-	./bin/ssvnc                                  (start GUI launcher)
-
-Use enhanced TightVNC unix viewer without SSL:
-
-	./bin/tightvncviewer far-away.east:0
-
-Use SSL to connect to a x11vnc server, and also verify the server's
-identity using the SSL Certificate in the file ./x11vnc.pem:
-
-	./bin/ssvnc_cmd -alpha -verify ./x11vnc.pem far-away.east:0
-
-(also turns on the viewer-side cursor alphablending hack). 
-
-
-Brief description of the subdirectories:
----------------------------------------
-
-	./bin/util		some utility scripts, e.g. ss_vncviewer
-				and ssvnc.tcl
-
-	./src			source code and patches.
-	./src/zips		zip files of source code and binaries.
-
-	./src/vnc_unixsrc	unpacked tightvnc source code tree.
-	./src/stunnel-4.14	unpacked stunnel source code tree.
-	./src/patches		patches to TightVNC viewer for the new
-				features on Unix (used by build.unix).
-	./src/tmp		temporary build dir for build.unix
-				(the last four are used by build.unix)
-
-
-	./man			man pages for TightVNC viewer and stunnel.
-
-	./Windows		Stock TightVNC viewer and Stunnel, Openssl
-				etc Windows binaries. ssvnc.exe is the
-				program to run.
-
-	./MacOSX		contains an unpacked Chicken of the VNC
-				viewer and a symlink to ssvnc.
-
-	./Unix			contains a symlink to ssvnc.
-
-Depending on which bundle you use not all of the above may be present.
-The smallest bundles with binaries are:
-
-	ssvnc_windows_only-1.x.y.zip   Windows
-	ssvnc_no_windows-1.x.y.tar.gz  Unix and MacOSX
-
-however, the tiny scripts only one (only 60KB) will run properly on Unix
-as long as you install external vncviewer and stunnel packages:
-
-	ssvnc_unix_minimal-1.x.y.tar.gz
-
-
-Untrusted Local Users:
----------------------
-
-    *IMPORTANT WARNING*:  If you run SSVNC on a workstation or computer
-    that other users can log into and you DO NOT TRUST these users
-    (it is a shame but sometimes one has to work in an environment like
-    this), then please note the following warning.
-
-    By 'do not trust' we mean they might try to gain access to remote
-    machines you connect to via SSVNC.  Note that an untrusted local
-    user can often obtain root access in a short amount of time; if a
-    user has achieved that, then all bets are off for ANYTHING that you
-    do on the workstation.  It is best to get rid of Untrusted Local
-    Users as soon as possible.
-
-    Both the SSL and SSH tunnels set up by SSVNC listen on certain ports
-    on the 'localhost' address and redirect TCP connections to the remote
-    machine; usually the VNC server running there (but it could also be
-    another service, e.g. CUPS printing).  These are the stunnel(8) SSL
-    redirection and the ssh(1) '-L' port redirection.  Because 'localhost'
-    is used only users or programs on the same workstation that is
-    running SSVNC can connect to these ports, however this includes any
-    local users (not just the user running SSVNC.)
-
-    If the untrusted local user tries to connect to these ports, he may
-    succeed in varying degrees to gain access to the remote machine.
-    We now list some safeguards one can put in place to try to make this
-    more difficult to achieve.
-
-    It probably pays to have the VNC server require a password, even
-    though there has already been SSL or SSH authentication (via
-    certificates or passwords).  In general if the VNC Server requires
-    SSL authentication of the viewer that helps, unless the untrusted
-    local user has gained access to your SSVNC certificate keys.
-
-    If the VNC server is configured to only allow one viewer connection
-    at a time, then the window of opportunity that the untrusted local
-    user can use is greatly reduced: he might only have a second or two
-    between the tunnel being set up and the SSVNC vncviewer connecting
-    to it (i.e. if the VNC server only allows a single connection, the
-    untrusted local user cannot connect once your session is established).
-    Similarly, when you disconnect the tunnel is torn down quickly and
-    there is little or no window of opportunity to connect (e.g. x11vnc
-    in its default mode exits after the first client disconnects).
-
-    Also for SSL tunnelling with stunnel(8) on Unix using one of the SSVNC
-    prebuilt 'bundles', a patched stunnel is provided that denies all
-    connections after the first one, and exits when the first one closes.
-    This is not true if the system installed stunnel(8) is used and is
-    not true when using SSVNC on Windows.
-
-    The following are two experimental features that are added to SSVNC
-    to improve the situation for the SSL/stunnel case.  Set them via
-    Options -> Advanced -> "STUNNEL Local Port Protections".
-
-    1) For SSL tunnelling with stunnel(8) on Unix there is a setting
-       'Use stunnel EXEC mode' (experimental) that will try to exec(2)
-       stunnel instead of using a listening socket.  This will require
-       using the specially modified vncviewer unix viewer provided
-       by SSVNC.  If this mode proves stable it will become the default.
-
-    2) For SSL tunnelling with stunnel(8) on Unix there is a setting
-       'Use stunnel IDENT check' (experimental) to limit socket
-       connections to be from you (this assumes the untrusted local
-       user has not become root on your workstation and has modified
-       your local IDENT check service; if he has you have much bigger
-       problems to worry about...)
-
-    There is also one simple LD_PRELOAD trick for SSH to limit the number
-    of accepted port redirection connections.  This makes the window of
-    time the untrusted local user can connect to the tunnel much smaller.
-    Enable it via Options -> Advanced -> "SSH Local Port Protections".
-    You will need to have the lim_accept.so file in your SSVNC package.
-
-    The main message is to 'Watch your Back' when you connect via the
-    SSVNC tunnels and there are users you don't trust on your workstation.
-    The same applies to ANY use of SSH '-L' port redirections or outgoing
-    stunnel SSL redirection services.
-

-This is a Windows utility to automatically start up STUNNEL to redirect

-SSL VNC connections to a remote host.  Then TightVNC Viewer (included)

-is launched to use this SSL tunnel.

-

-An example server would be "x11vnc -ssl", or any VNC server with a

-2nd STUNNEL program running on the server side.

-

-Just click on the program "ssvnc.exe", and then enter the remote

-VNC Server and click "Connect".  Click on "Help" for more information

-information.  You can also set some simple options under "Options ..."

-

-If you want that application to run in "SSH-ONLY" mode, click on

-the "sshvnc.bat" wrapper instead.  Or enter SSH_ONLY.

-

-Note that on Windows when the TightVNC viewer disconnects you may need to

-terminate the STUNNEL program manually.  To do this: Click on the STUNNEL

-icon (dark green) on the System Tray and then click "Exit".  Before that,

-however, you will be prompted if you want ssvnc.exe to try to terminate

-STUNNEL for you. (Note that even if STUNNEL termination is successful,

-the Tray Icon may not go away until the mouse hovers over it!)

-

-With this STUNNEL and TightVNC Viewer wrapper you can also enable using

-SSL Certificates with STUNNEL, and so the connection is not only encrypted

-but it is also not susceptible to man-in-the-middle attacks.

-

-See the STUNNEL and x11vnc documentation for how to create and add SSL

-Certificates (PEM files) for authentication.  Click on the "Certs ..."

-button to specify the certificate(s).  See the Help there for more info

-and also:

-	http://www.stunnel.org

-	http://www.openssl.org

-

-You can use x11vnc to create certificates if you like:

-

-

-Misc:

-

-	The openssl.exe stunnel.exe vncviewer.exe libeay32.dll

-	libssl32.dll programs came from the websites mentioned above.

-

-	IMPORTANT: some of these binaries may have cryptographic

-	software that you may not be allowed to download or use.

-	See the above websites for more information and also the

-        util/info subdirectories. 

-

-	Also, the kill.exe and tlist.exe programs in the w98 directory

-	came from diagnostic tools ftp site of Microsoft's.

-

-ssvnc - a GUI wrapper for SSL and SSH VNC connections.
-
-SYNOPSIS
-       ssvnc
-       ssvnc [host][:display]
-       ssvnc [saved-profile-name]
-       ssvnc [options] [host-or-profile]
-       ssvnc -cmd [ssvnc_cmd-args]
-       ssvnc --help
-
-DESCRIPTION
-       ssvnc  is  a tcl/tk gui wrapper that runs on Unix, MacOSX, and Windows.
-       It sets up an SSL or SSH tunnel to  the  remote  VNC  Server  and  then
-       launches  the  VNC  viewer (either the one provided or another one that
-       you have specified) to use that encrypted tunnel to connect to the  VNC
-       Server.   The  use  of  Proxies and Gateways to make the connections is
-       implemented.
-
-OPTIONS
-       -help, -h   Print this help.
-
-       --help Starts  up  the  GUI  as though the 'Help' button was pressed to
-              show the main Help panel.
-
-       -cmd [ssvnc_cmd-args]
-              Launch the ssvnc_cmd utility command directly (no GUI) with  the
-              given  arguments  (for use when ssvnc_cmd is not in one's PATH.)
-              If neither ssvnc_cmd nor ssvncviewer is in PATH, one can  launch
-              the viewer directly via: ssvnc -cmd -viewer [viewer-args]
-
-       -profiles
-              List the saved SSVNC profiles you have created.  A profile is  a
-              destination host with specific parameter settings.
-
-       -list  Same as -profiles
-
-       -ssh   Start  in  "SSH  Only Mode".  No SSL aspects are shown.  Same as
-              running the command sshvnc
-
-       -ts    Start in "Terminal Services  Mode".   This  is  like  "SSH  Only
-              Mode", but simpler and assumes x11vnc is available on the remote
-              side to start and manage X and VNC sessions.   Same  as  running
-              the command tsvnc
-
-       -tso   Same as -ts "Terminal Services Mode", however never let the user
-              leave this mode (no button to switch modes is  provided.)   Same
-              as SSVNC_TS_ALWAYS=1.
-
-       -ssl   Force the full GUI Mode: both SSL and SSH.  This is the default.
-              Same as -ss.
-
-       -nv    Toggle the "Verify All Certs" button to be off at startup.
-
-       -nvb   Never show the "Verify All Certs" button.  Same as SSVNC_NO_VER-
-              IFY_ALL_BUTTON=1.
-
-       -bigger
-              Make  the  Profile  Selection  Dialog  window  bigger.   Same as
-              SSVNC_BIGGER_DIALOG=1.
-
-       -noenc Start  off  in  a  mode  where a 'No Encryption' check button is
-              present.   You  can  toggle  the  mode  with  Ctrl-E.   Same  as
-              SSVNC_DISABLE_ENCRYPTION_BUTTON=1.  Or  noenc=1  in  ~/.ssvncrc.
-              Selecting no encryption is the same as  the  vnc://  and  Vnc://
-              prefixes  described  below.  The -noenc mode is now the default,
-              use -enc or noenc=0 for the opposite behavior.
-
-       -killstunnel
-              On Windows, automatically terminate the STUNNEL process when the
-              viewer  exits instead of prompting you (same as killstunnel=1 in
-              ssvnc_rc or toggle in Options menu)
-
-       -nokillstunnel
-              On Windows, disable -killstunnel mode.  Same as killstunnel=0 in
-              ssvnc_rc or toggle in Options menu.  Note that -killstunnel mode
-              is now the default.
-
-       -mycert /path/to/mycert.pem
-              Set the default "MyCert" to  be  /path/to/mycert.pem.   Same  as
-              -cert.  If the file does not exist, ~/.vnc/certs is prefixed and
-              tried. You can also set mycert=/path/to/mycert.pem in ~/.ssvncrc
-
-       -cacert /path/to/cacert.crt
-              Set the default "ServerCert" to be /path/to/cacert.crt.  Same as
-              -ca.  If the file does not exist, ~/.vnc/certs is  prefixed  and
-              tried. You can also set cacert=/path/to/cacert.crt in ~/.ssvncrc
-
-       -crl /path/to/mycrl.pem
-              Set   the   default   Certificate   Revocation   List   to    be
-              /path/to/mycrl.pem.  If the file does not exist, ~/.vnc/certs is
-              prefixed and tried.  You can also set crl=/path/to/mycrl.pem  in
-              ~/.ssvncrc.

-#
-# ssvnc_cmd:
-#
-#    A wrapper that calls ss_vncviewer to use the enhanced TightVNC viewer. 
-#
-# The enhanced TightVNC viewer features are:
-#
-#	- SSL support for connections using the co-bundled stunnel program.
-#	- rfbNewFBSize VNC support (screen resizing)
-#	- cursor alphablending with x11vnc at 32bpp
-#	- xgrabserver support for fullscreen mode (for old window mgrs)
-#
-#
-# Your platform (e.g. Linux.i686) is autodetected and enhanced
-# vncviewer and stunnel binaries for it are used (see the ./bin directory).
-#
-# See the build.unix script if your platform is not in this package.
-# You can also set the env. var. UNAME=os.arch to any "os.arch" you want
-# to override the autodetetion.
-#
-# Usage:
-#
-#     ssvnc_cmd [ss_vncviewer-args] hostname:N [vncviewer-args]
-#
-#  if, instead, this script is named "tightvncviewer" or "-viewer" is the
-#  first argument it calls the vncviewer directly (there is no encryption)
-#  and must be invoked as:
-#
-#     tightvncviewer [vncviewer-args] hostname:N
-#  or
-#     ssvnc_cmd -viewer [vncviewer-args] hostname:N
-#
-# In both cases, "hostname:N" is the host and VNC display to connect to,
-# e.g. snoopy:0. (-listen N and -appshare N modes works too.)
-#
-# See the script util/ss_vncviewer for details about its arguments:
-#
-#	-verify pemfile
-#	-mycert pemfile
-#	-proxy  phost:pport
-#	-alpha
-#	-grab
-#
-# N.B. if this script is named "tightvncviewer" the vncviewer is called
-# directly, and there won't be any SSL or SSH encryption tunnels.
-#
-# If the *very first* argument is "-cotvnc" then it is assumed you are on
-# Darwin and want to run the Chicken of the VNC viewer via our wrapper.
-#
-#
-# See the TightVNC viewer documentation for on its cmdline arguments.
-#
-# For convenience, here is the TightVNC 1.3dev5 viewer -help output:
-#
-#       TightVNC viewer version 1.3dev5
-#       
-#       Usage: vncviewer [<OPTIONS>] [<HOST>][:<DISPLAY#>]
-#              vncviewer [<OPTIONS>] [<HOST>][::<PORT#>]
-#              vncviewer [<OPTIONS>] -listen [<DISPLAY#>]
-#              vncviewer -help
-#       
-#       <OPTIONS> are standard Xt options, or:
-#               -via <GATEWAY>

-# ss_vncviewer:  wrapper for vncviewer to use an stunnel SSL tunnel
-#                or an SSH tunnel.

-# 
-# 
-# You must have stunnel(8) installed on the system and in your PATH
-# (however, see the -ssh option below, in which case you will need ssh(1)
-# installed)  Note: stunnel is usually installed in an "sbin" subdirectory.
-#
-# You should have "x11vnc -ssl ..." or "x11vnc -stunnel ..." 
-# already running as the VNC server on the remote machine.
-# (or use stunnel on the server side for any other VNC server)
-#
-#
-# Usage: ss_vncviewer [cert-args] host:display <vncviewer-args>
-#
-# e.g.:  ss_vncviewer snoopy:0
-#        ss_vncviewer snoopy:0 -encodings "copyrect tight zrle hextile"
-#
-# [cert-args] can be:
-#
-#	-verify /path/to/cacert.pem		
-#	-mycert /path/to/mycert.pem		
-#	-crl    /path/to/my_crl.pem  (or directory)
-#	-proxy  host:port
-#
-# -verify specifies a CA cert PEM file (or a self-signed one) for
-#         authenticating the VNC server.
-#
-# -mycert specifies this client's cert+key PEM file for the VNC server to
-#	  authenticate this client. 
-#
-# -proxy  try host:port as a Web proxy to use the CONNECT method
-#         to reach the VNC server (e.g. your firewall requires a proxy).
-#
-#         For the "double proxy" case use -proxy host1:port1,host2:port2
-#         (the first CONNECT is done through host1:port1 to host2:port2
-#         and then a 2nd CONNECT to the destination VNC server.)
-#
-#         Use socks://host:port, socks4://host:port, or socks5://host,port
-#         to force usage of a SOCKS proxy.  Also repeater://host:port and
-#         sslrepeater://host:port.
-#
-# -showcert  Only fetch the certificate using the 'openssl s_client'
-#            command (openssl(1) must in installed).  On ssvnc 1.0.27 and
-#            later the bundled command 'ultravnc_dsm_helper' is used.
-#
-#    See http://www.karlrunge.com/x11vnc/faq.html#faq-ssl-ca for details on
-#    SSL certificates with VNC.
-#
-# A few other args (not related to SSL and certs):
-#
-# -2nd    Run the vncviewer a 2nd time if the first connections fails.
-#
-# -ssh    Use ssh instead of stunnel SSL.  ssh(1) must be installed and you
-#         must be able to log into the remote machine via ssh.
-#
-#         In this case "host:display" may be of the form "user@host:display"
-#         where "user@host" is used for the ssh login (see ssh(1) manpage).
-#
-#         If -proxy is supplied it can be of the forms: "gwhost" "gwhost:port"
-#         "user@gwhost" or "user@gwhost:port".  "gwhost" is an incoming ssh 
-#         gateway machine (the VNC server is not running there), an ssh -L
-#         redir is used to "host" in "host:display" from "gwhost". Any "user@"
-#         part must be in the -proxy string (not in "host:display").
-#
-#         Under -proxy use "gwhost:port" if connecting to any ssh port
-#         other than the default (22).  (even for the non-gateway case,
-#         -proxy must be used to specify a non-standard ssh port)
-#
-#         A "double ssh" can be specified via a -proxy string with the two
-#         hosts separated by a comma:
-#
-#             [user1@]host1[:port1],[user2@]host2[:port2]
-#
-#         in which case a ssh to host1 and thru it via a -L redir a 2nd
-#         ssh is established to host2.  
-#
-#         Examples:
-#
-#         ss_vncviewer -ssh bob@bobs-home.net:0
-#         ss_vncviewer -ssh -sshcmd 'x11vnc -localhost' bob@bobs-home.net:0
-#
-#         ss_vncviewer -ssh -proxy fred@mygate.com:2022 mymachine:0
-#         ss_vncviewer -ssh -proxy bob@bobs-home.net:2222 localhost:0
-#
-#         ss_vncviewer -ssh -proxy fred@gw-host,fred@peecee localhost:0
-#
-# -sshcmd cmd   Run "cmd" via ssh instead of the default "sleep 15"
-#               e.g. -sshcmd 'x11vnc -display :0 -localhost -rfbport 5900'
-#
-# -sshargs "args"  pass "args" to the ssh process, e.g. -L/-R port redirs.
-#
-# -sshssl Tunnel the SSL connection thru a SSH connection.  The tunnel as
-#         under -ssh is set up and the SSL connection goes thru it.  Use
-#         this if you want to have and end-to-end SSL connection but must
-#         go thru a SSH gateway host (e.g. not the vnc server).  Or use
-#         this if you need to tunnel additional services via -R and -L 
-#         (see -sshargs above).
-#
-#         ss_vncviewer -sshssl -proxy fred@mygate.com mymachine:0
-#
-# -listen (or -reverse) set up a reverse connection.
-#
-# -alpha  turn on cursor alphablending hack if you are using the
-#         enhanced tightvnc vncviewer.
-#
-# -grab   turn on XGrabServer hack if you are using the enhanced tightvnc
-#         vncviewer (e.g. for fullscreen mode in some windowmanagers like
-#         fvwm that do not otherwise work in fullscreen mode)
-#
-#

-
-	set msg {
- Terminal Services:
-
-    The Terminal Services VNC Viewer uses SSH to establish an encrypted
-    and authenticated connection to the remote server.
-
-    Through the SSH channel, it automatically starts x11vnc in terminal
-    services mode on the remote server to find or create your desktop
-    session.  x11vnc is used for both the session management and the
-    VNC transport.
-
-    You MUST be able to log in via SSH to the remote terminal server.
-    Ask your administrator to set this up for you if it isn't already.
-    x11vnc must also be installed on the remote server machine.
-    See "Requirements" below.
-
-    This mode is started by the commands 'tsvnc' or 'ssvnc -ts' or
-    toggled by pressing Ctrl-t.  "SSVNC Mode" under Options -> Advanced
-    will also return to the full SSVNC.
-
-    Or in your ~/.ssvncrc (or ~/ssvnc_rc on Windows) put "mode=tsvnc"
-    to have the tool always start up in that mode.  To constrain the UI,
-    run with -tso or SSVNC_TS_ALWAYS set to prevent leaving the Terminal
-    Services mode.
-
-
- Hosts and Displays:
-
-    Enter the remote VNC Terminal Services hostname in the
-    'VNC Terminal Server' entry.
-
-    Examples:
-
-           24.67.132.27
-           far-away.east
-           fred@someplace.no
-    
-    Then click on "Connect".
-
-    Once the SSH is running (you may need to type a password or accept
-    a new ssh key in the terminal window that pops up), the VNC Viewer
-    will be automatically started directed to the local port of the SSH
-    tunnel which, in turn, encrypts and redirects the connection to the
-    remote VNC server.
-
-    x11vnc is run remotely to find or create your terminal services desktop
-    session.  It must be installed and accessible on the remote system.
-
-    Enter "user@hostname.com" in 'VNC Terminal Server' if the remote
-    username is different from the yours on this machine.  On Windows
-    you *MUST* supply the remote username due to a deficiency in Plink.
-    This entry is passed to SSH; it could also be an SSH alias you have
-    created (in ~/.ssh/config).
-
-    If the remote SSH server is run on a non-standard port, e.g. 2222, use
-    something like one of these:
-
-           far-away.east:2222
-           fred@someplace.no:2222
-
-    (unlike SSVNC mode, the number is the SSH port, not the VNC display)
-
-    If you find yourself in the unfortunate circumstance that your ssh 
-    username has a space in it, use %SPACE (or %TAB) like this:
-
-           fred%SPACEflintstone@xyzzy.net
-
-
- Zeroconf/Bonjour:
-
-    On Unix or Mac OS X, if the 'avahi-browse' or 'dns-sd' command is
-    available on the system and in your PATH, a 'Find' button is placed by
-    'VNC Host:Display'.  Clicking on Find will try to find VNC Servers
-    on your Local Network that advertize via the Zeroconf protocol.
-    A menu of found hosts is presented for you to select from.
-
-
- Profiles:
-
-    Use "Save" to save a profile (i.e. a host:display and its specific
-    settings) with a name.  The "TS-" prefix will be suggested to help
-    you distinguish between Terminal Services and regular profiles.
-
-    To load in a saved Options profile, click on the "Load" button,
-    and choose which one you want.
-
-    To list your profiles from the command line use:
-
-         tsvnc -profiles    (or -list)
-
-    To launch profile1 directly from the command-line, or to a server
-    use things like: 
-
-         tsvnc profile1
-         tsvnc /path/to/profile1.vnc
-         tsvnc hostname
-         tsvnc user@hostname
-
-    Note that the 'Verify All Certs' setting is NOT saved in profiles.
-
-
- Proxies/Gateways:
-
-    Proxy/Gateway is usually a gateway machine to log into via SSH that is
-    not the machine running the VNC terminal services.  However, Web and
-    SOCKS proxies can also be used (see below).
-
-    For example if a company had a central login server: "ssh.company.com"
-    (accessible from the internet) and the internal server name was
-    "ts-server", one could put in
-
-           VNC Terminal Server:   ts-server
-           Proxy/Gateway:         ssh.company.com
-
-    It is OK if the hostname "ts-server" only resolves inside the firewall.
-
-    The 2nd host, ts-server in this example, MUST also be running an SSH
-    server and you must be able to log into it.  You may need to supply
-    a 2nd password to it to login.
-
-    Use username@host (e.g. joe@ts-server or jsmith@ssh.company.com)
-    if the user name differs between machines.
-
-    NOTE: On Windows you MUST always supply the username@ because putty's
-    plink requires it.
-
-
-    NON-STANDARD SSH PORT: To use a non-standard ssh port (i.e. a port other
-    than 22) you need to use the Proxy/Gateways as well.  E.g. something
-    like this for port 2222:
-    
-           VNC Terminal Server:  ts-server
-           Proxy/Gateway:        jsmith@ssh.company.com:2222
-
-    On Unix/MacOSX the username@ is not needed if it is the same as on this
-    machine.
-
-
-    A Web or SOCKS proxy can also be used.  Use this if you are inside a
-    firewall that prohibits direct connections to remote SSH servers.
-    In Terminal Services SSH mode, the "http://" prefix is required for
-    web proxies.
-
-           VNC Terminal Server:  fred@someplace.no
-           Proxy/Gateway:        http://myproxy.west:8080
-
-    or for SOCKS:
-
-           VNC Terminal Server:  fred@someplace.no
-           Proxy/Gateway:        socks://mysocks.west:1080
-
-    use socks5://... to force the SOCKS5 version.  For a non-standard
-    port the above would be, e.g., fred@someplace.no:2222
-
-    As with a username that contains a space, use %SPACE (or %TAB) to
-    indicate it in the SSH proxies, e.g. john%SPACEsmith@ssh.company.com
-
-    One can also chain proxies and other things.  See the section
-    "SSH Proxies/Gateways" in the Main SSVNC Help for full details.
-

-
-           - Unix ssvncviewer    (set options for supplied Unix viewer)
-
-
- Requirements:
-
-    When running this application on Unix/MacOSX the ssh(1) program must
-    be installed locally.  On Windows a plink/putty binary is included.
-
-    On the remote VNC Terminal Services host, x11vnc must be installed
-    (0.9.3 or higher), and at least one virtual X server: Xvfb, Xdummy,
-    or Xvnc must be available.  Xvfb is the most often used one.  All of
-    these programs must be available in $PATH on the remote server when
-    logged in via SSH.
-
-    The VNC terminal services administrator can make "x11vnc" be a wrapper
-    script that sets everything up correctly and then runs the real x11vnc. 
-
-
- Real X servers:
-
-    As a *BONUS*, if on the remote host, say a workstation, you have a
-    regular X session running on the physical hardware that you are
-    ALREADY logged into you can access to that display as well (x11vnc
-    will find it).
-
-    So this tool can be used as a simple way to launch x11vnc to find
-    your real X display on your workstation and connect to it.
-
-    The Printing and Sound redirection won't work for this mode however.
-    You will need to use the full SSVNC application to attempt that.
-
-    If you (mistakenly) have not logged into an X session on the real
-    X server on the workstation, a VIRTUAL (Xvfb, etc.) server will be
-    created for you (that may or may not be what you want).
-
-    The X Login Advanced setting can be used to connect to a X Display
-    Manger Greeter login panel (no one is logged in yet).  This requires
-    sudo(1) privileges on the remote machine.

- Hosts and Displays:
-
-    Enter the VNC host and display in the  'VNC Host:Display'  entry box.
-    
-    It is of the form "host:number", where "host" is the hostname of the
-    machine running the VNC Server and "number" is the VNC display number;
-    it is often "0".  Some Examples:
-
-           snoopy:0
-
-           far-away.east:0
-
-           sunray-srv1.west:17
-
-           24.67.132.27:0
-    
-    Then click on "Connect".  When you do the STUNNEL program will be started
-    locally to provide you with an outgoing SSL tunnel.
-
-    Once the STUNNEL is running, the TightVNC Viewer (Or perhaps Chicken of
-    the VNC on Mac OS X, or one you set under Options) will be automatically
-    started and directed to the local port of the SSL tunnel which, in turn,
-    encrypts and redirects the connection to the remote VNC server.
-
-    The remote VNC server **MUST** support an initial SSL/TLS handshake before
-    using the VNC protocol (i.e. VNC is tunnelled through the SSL channel
-    after it is established).  "x11vnc -ssl ..."  does this, and any VNC server
-    can be made to do this by using, e.g., STUNNEL or socat on the remote side.
-    SSVNC also supports VeNCrypt and ANONTLS SSL/TLS VNC servers (see below.)
-
-    * Automatic SSH Tunnels are described below.
-
-    * The 'No Encryption' / 'None' option provides a direct connection without
-      encryption (disable the button with the -enc option, or Options menu.)
-      More info in Tip 5.
-
- Port numbers:
-
-    If you are using a port less than the default VNC port 5900 (usually
-    the VNC display = port - 5900), use the full port number itself, e.g.:
-    
-         24.67.132.27:443
-    
-    Note, however, if the number n after the colon is < 200, then a
-    port number 5900 + n is assumed; i.e. n is the VNC display number.
-    If you must use a TCP port less than 200, specify a negative value,
-    e.g.:  24.67.132.27:-80
- 
-    For Reverse VNC connections (listening viewer, See Tip 2 and
-    Options -> Help), the port mapping is similar, except "listening
-    display :0" corresponds to port 5500, :1 to 5501, etc.
-    Specify a specific interface, e.g. 192.168.1.1:0 to have stunnel
-    listen on that interface only.  Listening on IPv6 can also be done, use
-    e.g. :::0 or ::1:0  This listening on IPv6 (:::0) works for UN-encrypted
-    reverse connections as well (mode 'None').
-
-
- Zeroconf/Bonjour:
-
-    On Unix or Mac OS X, if the 'avahi-browse' or 'dns-sd' command is
-    available on the system and in your PATH, a 'Find' button is placed by
-    'VNC Host:Display'.  Clicking on Find will try to find VNC Servers on
-    your Local Network that advertize via the Zeroconf protocol.  A menu of
-    found hosts is presented for you to select from.
-
-
- VNC Password:
-
-    On Unix or MacOSX IF there is a VNC password for the server you can
-    enter it in the "VNC Password:" entry box.
-
-    This is *REQUIRED* on MacOSX when Chicken of the VNC is used, because
-    that viewer does not put up a user password prompt when it learns
-    that a password is needed.
-
-    On Unix (including MacOSX using the X11 viewer) if you choose not to
-    enter the password you will simply be prompted for it in the terminal
-    window running TightVNC viewer if one is required.
-
-    On Windows TightVNC viewer will prompt you if a password is required.
-
-    NOTE: when you Save a VNC profile, the password is NOT saved (you need
-    to enter it each time).  Nor is the 'Verify All Certs' setting.
-
-
- Profiles:
-
-    Use "Save" to save a profile (i.e. a host:display and its specific
-    settings) with a name.
-
-    To load in a saved Options profile, click on the "Load" button.
-
-    To list your profiles from the command line use: 
-
-        ssvnc -profiles    (or -list)
-
-    You can launch ssvnc and have it immediately connect to the server
-    by invoking it something like this:
-
-        ssvnc profile1              (launches profile named "profile1")
-        ssvnc /path/to/profile.vnc  (loads the profile file, no launching)
-        ssvnc hostname:0            (connect to hostname VNC disp 0 via SSL)
-        ssvnc vnc+ssl://hostname:0  (same)
-        ssvnc vnc+ssh://hostname:0  (connect to hostname VNC disp 0 via SSH)
-
-    see the Tips 5 and 7 for more about the URL-like syntax.
-
-    If you don't want "ssvnc profile1" to immediately launch the connection
-    to the VNC server set the SSVNC_PROFILE_LOADONLY env. var. to 1.
-    (or specify the full path to the profile.vnc as shown above.)
-
-
- SSL Certificate Verification:
-
-    *** IMPORTANT ***: If you do not take the steps to VERIFY the VNC Server's
-    SSL Certificate, you are in principle vulnerable to a Man-In-The-Middle
-    attack.  Without SSL Certificate verification, only passive network
-    sniffing attacks will be guaranteed to be prevented.  There are hacker
-    tools like dsniff/webmitm and cain that implement SSL Man-In-The-Middle
-    attacks.  They rely on the client user not bothering to check the cert.
-
-    Some people may be confused by the above because they are familiar with
-    their Web Browser using SSL (i.e. https://... websites) and those sites
-    are authenticated securely without the user's need to verify anything
-    manually.  The reason why this happens automatically is because 1) their
-    web browser comes with a bundle of Certificate Authority certificates
-    and 2) the https sites have paid money to the Certificate Authorities to
-    have their website certificate signed by them.  When using SSL in VNC we
-    normally do not do something this sophisticated, and so we have to verify
-    the certificates manually.  However, it is possible to use Certificate
-    Authorities with SSVNC; that method is described below.
-
-    You can use the "Fetch Cert" button to retrieve the Cert and then
-    after you check it is OK (say, via comparing the MD5 or other info)
-    you can "Save" it and use it to verify future connections to servers.
-    (However, see the note at the end of this section about CA certificates.)
-
-    When "Verify All Certs" is checked, this check is always enforced,
-    and so the first time you connect to a new server you may need to
-    follow a few dialogs to inspect and save the server certificate.
-    See the "Certs... -> Help" for information on how to manage certificates.
-
-    "Verify All Certs" is on by default.
-
-    Note, however, "Fetch Cert" and "Verify All Certs" are currently disabled
-    in the very rare "SSH + SSL" usage mode to avoid SSHing in twice.
-    You can manually set a ServerCert or CertsDir in this case if you like.
-
-
-    Advanced Method: Certificate Authority (CA):
-
-    If you, or your site administrator, goes though the steps of setting up
-    a Certificate Authority (CA) to sign the VNC server and/or VNC client
-    Certs, that can be used instead and avoids the need to manually verify
-    every cert while still authenticating every connection.  More info:
-    http://www.karlrunge.com/x11vnc/faq.html#faq-ssl-ca
-
-    See the cmdline option -cacert file below in 'SSL Certificates'
-    for setting a default ServerCert/CA Cert.
-
-    You may also Import the CA Cert and save it to the 'Accepted Certs'
-    directory so the "Verify All Certs" automatic checking will find it.
-
-    Note that if a Server is using a CA signed certificate instead of
-    its own Self-Signed one, then the default "Verify All Certs/Fetch Cert"
-    saving mechanism will NOT succeed.  You must obtain the CA certificate
-    and explicitly set it as the ServerCert or Import it to Accepted Certs.
-
-
- SSL/TLS Variants; VeNCrypt and ANONTLS:
-
-    SSVNC can also connect to VNC SSL/TLS variants; namely the VeNCrypt and
-    "TLS" VNC Security types.  Vino uses the latter (we call it "ANONTLS");
-    and a growing number use VeNCrypt (QEMU, ggi, virt-manager, VeNCrypt, Xen.)
-
-    Via the VeNCrypt bridge that SSVNC provides, the VeNCrypt/ANONTLS
-    support ALSO works with ANY 3rd party VNC Viewers you specify via
-    'Change VNC Viewer' (e.g. RealVNC, TightVNC, UltraVNC, etc.) that do
-    not directly support VeNCrypt or ANONTLS.  This works on all platforms:
-    Unix, MacOSX, and Windows.
-
-
-    Notes on VeNCrypt/ANONTLS Auto-detection:
-
-    IMPORTANT: VeNCrypt Server Auto-detection *ONLY* occurs in SSL mode
-    and when an initial fetch-cert action takes place.
-
-    While the initial certificate fetch is taking place SSVNC applies
-    heuristics to try to automatically detect the VeNCrypt or ANONTLS
-    protocol use by the VNC server.  This way it learns that the server
-    is using it and then knows to switch to VeNCrypt encrypted SSL/TLS at
-    the right point.  Then SSVNC makes a second (the real) connection to 
-    VNC server and connects the VNC viewer to it.
-
-    In the default "Verify All Certs" mode, a fetch cert action always
-    takes place, and so VeNCrypt/ANONTLS will be autodected.
-
-    However, if you have specified an explicit ServerCert or disabled
-    "Verify All Certs" then even though the initial fetch cert action is no
-    longer needed, it is performed anyway because it allows VeNCrypt/ANONTLS
-    auto-detection.
-
-    To disabled this initial fetch (e.g. you know the VNC server is normal
-    SSL and not VeNCrypt/ANONTLS and want to connect more quickly) then
-    select "Do not Probe for VeNCrypt" in the Advanced Options menu.
-
-    On the other hand, if you know the VNC server ONLY supports VeNCrypt or
-    ANONTLS, to improve the accuracy and speed with which the connection
-    takes place, you can specify the one or both of the 'Server uses
-    VeNCrypt SSL encryption' and 'Server uses Anonymous Diffie-Hellman'
-    in the 'Advanced' options panel.  That way guessing via an initial
-    probe is not needed or performed.  See each options's Advanced Options
-    Help for more info.
-
-    Note that if you are using VeNCrypt or ANONTLS for REVERSE connections
-    (Listen) then you *MUST* set the 'Server uses VeNCrypt SSL encryption'
-    (and the ANON-DH if it applies) option in Advanced.  Note also that
-    REVERSE VeNCrypt and ANONTLS connections currently do not work on
-    Windows.
-
-    Also, if you are using the "Use SSH+SSL" double tunnel, you MUST set
-    'Server uses VeNCrypt SSL encryption' (and the ANON-DH if it applies)
-    because the initial fetch cert is disabled in SSH+SSL mode.
-
-
- Deciphering SSL Negotiation Success or Failure:
-
-    Since SSVNC is a "glue program", in this case gluing VNCViewer and stunnel
-    together (with possibly a proxy helper) reporting is clumsy at best.
-    (In SSH encryption mode, it glues to ssh instead of stunnel.)  In most
-    cases the programs being "glued" are run in a terminal window where you
-    can see the program's output.  On Windows you will need to double click
-    on the stunnel tray icon to view its log.
-
-    Although the output is quite cryptic, you are encouraged to learn to
-    recognize some of the errors reported in it.
-
-    Here is stunnel output for a case of successfully verifying the VNC
-    Server's Certificate:
-
-      2008.11.20 08:09:39 LOG5[1472]: VERIFY OK: depth=0, /C=AU/L=...
-      2008.11.20 08:09:39 LOG6[1472]: SSL connected: new session negotiated
-      2008.11.20 08:09:39 LOG6[1472]: Negotiated ciphers: AES256-SHA SSLv3 ...
-
-    Here is a case where the Server's Cert did not match the ServerCert
-    we set:
-
-      2008.11.20 08:12:31 LOG4[1662]: VERIFY ERROR: depth=0, error=self ...
-      2008.11.20 08:12:31 LOG3[1662]: SSL_connect: 14090086: error:14090086:SSL
-           routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed
-
-    Here is a case where the Server's Cert has expired:
-
-      2009.12.27 12:20:25 LOG4[25500]: VERIFY ERROR: depth=0, error=certificate
-           has expired: /C=AU/L=...
-      2009.12.27 12:20:25 LOG3[25500]: SSL_connect: 14090086: error:14090086:SSL
-           routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed
-
-
-    If you disable "Verify All Certs" and do not supply a ServerCert,
-    then there will be no 'VERIFY ...' in the output because the SSVNC
-    stunnel accepts the server's cert without question (this is insecure.)
-
-    Also in the output will be messages about whether the SSL VNC server
-    rejected your connection because it requires you to authenticate
-    yourself with a certificate (MyCert).  Here is the case when you
-    supplied no MyCert:
-
-      2008.11.20 08:16:29 LOG3[1746]: SSL_connect: 14094410: error:14094410:
-          SSL routines:SSL3_READ_BYTES:sslv3 alert handshake failure
-
-    or you used a certificate the server did not recognize:
-
-      2008.11.20 08:18:46 LOG3[1782]: SSL_connect: 14094412: error:14094412:
-          SSL routines:SSL3_READ_BYTES:sslv3 alert bad certificate
-
-    or your certificate has been revoked:
-
-     2008.11.20 08:20:08 LOG3[1913]: SSL_connect: 14094414: error:14094414:
-         SSL routines:SSL3_READ_BYTES:sslv3 alert certificate revoked
-
-
- SSH:
-
-    Click on "Use SSH" if you want to use an *SSH* tunnel instead of SSL
-    (then the VNC Server does not need to speak SSL or use STUNNEL or socat).
-
-    You will need to be able to login to your account on the remote host
-    via SSH (e.g. via password, ssh keys, or ssh-agent).
-
-    Specify the SSH hostname and VNC display in the VNC Host:Display entry.
-    Use something like:
-
-           username@far-away.east:0
-
-    if your remote username is different from the one on the local viewer
-    machine.
-
-    On Windows you *MUST* supply the "username@" part because Putty/Plink
-    needs it to work correctly.
-
-    "SSH + SSL" is similar but its use is more rare because it requires 2
-    encrypted tunnels to reach the VNC server. See the Help under Options
-    for more info.
-
-    To connect to a non-standard SSH port, see SSH Proxies/Gateways section.
-
-    See Tip 8) for how to make this application be SSH-only with the -ssh
-    command line option or "sshvnc".
-
-    If you find yourself in the unfortunate circumstance that your ssh 
-    username has a space in it, use %SPACE (or %TAB) like this:
-
-           fred%SPACEflintstone@xyzzy.net:0
-
- Remote SSH Command:
-
-    In SSH or SSH + SSL mode you can also specify a remote command to run
-    on the remote ssh host in the "Remote SSH Command" entry.  The default
-    is just to sleep a bit (e.g. sleep 15) to make sure the tunnel ports
-    are established.  Alternatively you could have the remote command start
-    the VNC server, e.g.
-
-         x11vnc -display :0 -rfbport 5900 -localhost -nopw
-
-    When starting the VNC server this way, note that sometimes you will need
-    to correlate the VNC Display number with the "-rfbport" (or similar)
-    option of the server.  E.g. for VNC display :2
-
-         VNC Host:Display       username@somehost.com:2
-         Remote SSH Command:    x11vnc -find -rfbport 5902 -nopw
-
-    See the Tip 18) for using x11vnc PORT=NNNN feature (or vncserver(1)
-    output) to not need to specify the VNC display number or the x11vnc
-    -rfbport option.
-
-    Windows SSH SERVER: if you are ssh'ing INTO Windows (e.g. CYGWIN SSHD
-    server) there may be no "sleep" command so put in something like
-    "ping localhost" or "ping -n 10 -w 1000 localhost" to set a short
-    delay to let the tunnel ports get established.
-
-
- SSL Certificates:
-
-    If you want to use a SSL Certificate (PEM) file to authenticate YOURSELF to
-    the VNC server ("MyCert") and/or to verify the identity of the VNC Server
-    ("ServerCert" or "CertsDir") select the certificate file by clicking the
-    "Certs ..." button before connecting.
-
-    Certificate verification is needed to prevent Man-In-The-Middle attacks;
-    if it is not done then only passive network sniffing attacks are prevented.
-    There are hacker tools like dsniff/webmitm and cain that implement SSL
-    Man-In-The-Middle attacks.  They rely on the client user not bothering to
-    check the cert.
-
-
-    See the x11vnc documentation:
-
-           http://www.karlrunge.com/x11vnc/ssl.html
-
-    for how to create and use PEM SSL certificate files.  An easy way is:
-
-           x11vnc -ssl SAVE ...
-
-    where it will print out its automatically generated certificate to the
-    screen and that can be copied safely to the viewer side.
-
-    You can also use the "Create Certificate" feature of this program under
-    "Certs ...".  Just click on it and follow the instructions in the dialog.
-    Then copy the cert file to the VNC Server and specify the other one in
-    the "Certs ..." dialog.
-
-    Alternatively you can use the "Import Certificate" action to paste in a
-    certificate or read one in from a file.  Or you can use the "Fetch Cert"
-    button on the main panel.  If "Verify All Certs" is checked, you will
-    be forced to check Certs of any new servers the first time you connect.
-
-    Note that "Verify All Certs" is on by default so that users who do not
-    understand the SSL Man-In-The-Middle problem will not be left completely
-    vulnerable to it (everyone still must make the effort to verify new
-    certificates by an external method to be completely safe).
-
-    To have "Verify All Certs" toggled off at startup, use "ssvnc -nv" or
-    set SSVNC_NO_VERIFY_ALL=1 before starting.  If you do not even want to
-    see the button, use "ssvnc -nvb" or SSVNC_NO_VERIFY_ALL_BUTTON=1.
-
-    Use the "-mycert file" option (same as "-cert file") to set a default
-    MyCert.  This is the same as "mycert=file" (also "cert=file") in the
-    ~/.ssvncrc file.  See Certs -> Help for more info.
-
-    Use the "-cacert file" option (same as "-ca file") to set a default
-    ServerCert (or CA).  This is the same as "cacert=file" (also "ca=file")
-    in the ~/.ssvncrc file.  See Certs -> Help for more info.
-
-    Use the "-crl file" option to set a default CRL File.  This is the same
-    as "crl=file" in the ~/.ssvncrc file.  See Certs -> Help for more info.
-
-    Prefix any of these files with "FORCE:" to make them immutable.

- Windows STUNNEL problems:
-
-    Note that on Windows when the Viewer connection is finished by default
-    SSVNC will try to kill the STUNNEL process for you.
-
-    If Options -> Kill Stunnel Automatically is not set you will be
-    prompted if you want SSVNC to try to kill the STUNNEL process for you.
-    Usually you will say Yes, however if there are problems connecting
-    you may want to look at the STUNNEL Log first.
-
-    Before it is killed, double clicking the STUNNEL tray icon (dark green)
-    will show you its Log file (useful for debugging connection problems).
-
-    Even though SSVNC will kill the STUNNEL process for you, you will
-    still need to move the mouse over the icon to make the little picture
-    go away!!!  This is unfortunate but there does not seem to be a way
-    to avoid it.
-
-    In some cases you may need to terminate STUNNEL manually from the System
-    Tray (right click on dark green icon) and selecting "Exit".
-
-    Use -nokillstunnel or killstunnel=0 in ~/.ssvncrc to have SSVNC
-    start up with stunnel killing disabled.
-
- Untrusted Local Users:
-
-    *IMPORTANT WARNING*:  If you run SSVNC on a workstation or computer
-    that other users can log into and you DO NOT TRUST these users
-    (it is a shame but sometimes one has to work in an environment like
-    this), then please note the following warning.
-
-    By 'do not trust' we mean they might try to gain access to remote
-    machines you connect to via SSVNC.  Note that an untrusted local
-    user can often obtain root access in a short amount of time; if a
-    user has achieved that, then all bets are off for ANYTHING that you
-    do on the workstation.  It is best to get rid of Untrusted Local
-    Users as soon as possible.
-
-    Both the SSL and SSH tunnels set up by SSVNC listen on certain ports
-    on the 'localhost' address and redirect TCP connections to the remote
-    machine; usually the VNC server running there (but it could also be
-    another service, e.g. CUPS printing).  These are the stunnel(8) SSL
-    redirection and the ssh(1) '-L' port redirection.  Because 'localhost'
-    is used only users or programs on the same workstation that is
-    running SSVNC can connect to these ports, however this includes any
-    local users (not just the user running SSVNC.)
-
-    If the untrusted local user tries to connect to these ports, he may
-    succeed by varying degrees to gain access to the remote machine.
-    We now list some safeguards one can put in place to try to make this
-    more difficult to achieve.
-
-    It probably pays to have the VNC server require a password, even
-    though there has already been SSL or SSH authentication (via
-    certificates or passwords).  In general if the VNC Server requires
-    SSL authentication of the viewer that helps, unless the untrusted
-    local user has gained access to your SSVNC certificate keys.
-
-    If the VNC server is configured to only allow one viewer connection
-    at a time, then the window of opportunity that the untrusted local
-    user can use is greatly reduced: he might only have a second or two
-    between the tunnel being set up and the SSVNC vncviewer connecting
-    to it (i.e. if the VNC server only allows a single connection, the
-    untrusted local user cannot connect once your session is established).
-    Similarly, when you disconnect the tunnel is torn down quickly and
-    there is little or no window of opportunity to connect (e.g. x11vnc
-    in its default mode exits after the first client disconnects).
-
-    Also for SSL tunnelling with stunnel(8) on Unix using one of the SSVNC
-    prebuilt 'bundles', a patched stunnel is provided that denies all
-    connections after the first one, and exits when the first one closes.
-    This is not true if the system installed stunnel(8) is used and is
-    not true when using SSVNC on Windows.
-
-    The following are experimental features that are added to SSVNC to
-    improve the situation for the SSL/stunnel and SSH cases.  Set them
-    via Options -> Advanced -> "STUNNEL Local Port Protections" or
-    "SSH Local Port Protections".
-
-    STUNNEL:
-
-    1) For SSL tunnelling with stunnel(8) on Unix there is a setting
-       'Use stunnel EXEC mode' that will try to exec(2) stunnel
-       instead of using a listening socket.  This will require using
-       the specially modified vncviewer unix viewer provided by SSVNC.
-       The mode works well and is currently set as the default.
-       Disable it if it causes problems or conflicts.
-
-    2) For SSL tunnelling with stunnel(8) on Unix there is a setting
-       'Use stunnel IDENT check' (experimental) to limit socket
-       connections to be from you (this assumes the untrusted local
-       user has not become root on your workstation and has modified
-       your local IDENT check service; if he has you have much bigger
-       problems to worry about...)
-
-       Neither of the above methods are available on Windows.
-
-    SSH:
-
-    1) There is also a simple LD_PRELOAD trick for SSH to limit the
-       number of accepted port redirection connections.  This makes the
-       window of time the untrusted local user can connect to the tunnel
-       much smaller.  Enable it via Options -> Advanced -> "SSH Local
-       Port Protections".  You will need to have the lim_accept.so file
-       in your SSVNC package.  The mode works well and is currently set
-       as the default.  Disable it if it causes problems or conflicts.
-
-       The above method is not available on Windows.
-
-    The main message is to 'Watch your Back' when you connect via the
-    SSVNC tunnels and there are users you don't trust on your workstation.
-    The same applies to ANY use of SSH '-L' port redirections or outgoing
-    stunnel SSL redirection services.

-	set help_prox {
- Here are a number of long sections on all sorts of proxies, Web, SOCKS,
- SSH tunnels/gateways, UltraVNC, Single Click, etc., etc.
-
-
- Proxies/Gateways:
-
-    If an intermediate proxy is needed to make the SSL connection
-    (e.g. a web gateway out of a firewall) enter it in the "Proxy/Gateway"
-    entry box:
-
-           VNC Host-Display:   host:number
-           Proxy/Gateway:      proxy-host:port
-    e.g.:
-           VNC Host-Display:   far-away.east:0
-           Proxy/Gateway:      myproxy.west:8080
-
-
-    If the "double proxy" case is required (e.g. coming out of a web
-    proxied firewall environment and then INTO a 2nd proxy to ultimately
-    reach the VNC server), separate them via a comma, e.g.:
-
-           VNC Host-Display:   far-away:0
-           Proxy/Gateway:      myproxy.west:8080,myhome.net:443
-
-    So it goes: viewer -> myproxy.west -> myhome.net -> far-away (VNC)
-
-    The proxies are assumed to be Web proxies.  To use SOCKS proxies:
-
-           VNC Host-Display:   far-away.east:0
-           Proxy/Gateway:      socks://mysocks.west:1080
-
-    Use socks5:// to force the SOCKS5 proxy protocol (e.g. for ssh -D).
-
-    You can prefix web proxies with http:// in SSL mode but it doesn't matter
-    since that is the default for a proxy.  (NOTE that in SSH or SSH+SSL
-    mode you MUST supply the http:// prefix for web proxies because in those
-    modes an SSH tunnel is the default proxy type: see the next section.)
-
-    Note that Web proxies are often configured to ONLY allow outgoing
-    connections to ports 443 (HTTPS) and 563 (SNEWS), so you might
-    have run the VNC server (or router port redirector) on those ports.
-    SOCKS proxies usually have no restrictions on port number.
-
-    You can chain up to 3 proxies (any combination of web (http://) and
-    socks://) by separating them with commas (i.e. first,second,third).
-
-    Proxies also work for un-encrypted connections ("None" or vnc://, Tip 5)
-
-    See the ss_vncviewer description and x11vnc FAQ for info on proxies:
-
-        http://www.karlrunge.com/x11vnc/faq.html#ss_vncviewer
-        http://www.karlrunge.com/x11vnc/faq.html#faq-ssl-java-viewer-proxy
-
-
- SSH Proxies/Gateways:
-
-    Proxy/Gateway also applies to SSH mode, it is a usually a gateway SSH
-    machine to log into via ssh that is not the workstation running the
-    VNC server.  However, Web and SOCKS proxies can also be used (see below).
-
-    For example if a company had a central login server: "ssh.company.com"
-    (accessible from the internet) and the internal workstation with VNC was
-    named "joes-pc", then to create an SSH tunnel one could put this in:
-
-           VNC Host:Display:   joes-pc:0
-           Proxy/Gateway:      ssh.company.com
-
-    It is OK if the hostname "joes-pc" only resolves inside the firewall.
-
-    The 2nd leg, from ssh.company.com -> joes-pc is done by a ssh -L
-    redir and is not encrypted (but the viewer -> ssh.company.com 1st leg is
-    an encrypted tunnel). 
-
-    To SSH encrypt BOTH legs, try the "double SSH gateway" method using
-    the "comma" notation:
-
-           VNC Host:Display:   localhost:0
-           Proxy/Gateway:      ssh.company.com,joes-pc
-
-    this requires an SSH server also running on joes-pc.  So an initial SSH
-    login is done to ssh.company.com, then a 2nd SSH is performed (through
-    port a redirection of the first) to login straight to joes-pc where
-    the VNC server is running.
-
-    Use username@host (e.g. joe@joes-pc  jsmith@ssh.company.com) if the
-    user names differ between the various machines.  
-
-    NOTE: On Windows you MUST always supply the username@ because putty's
-    plink requires it.

-
-    NON-STANDARD SSH PORT: To use a non-standard ssh port (i.e. a port other
-    than 22) you need to use the Proxy/Gateways as well.  E.g. something
-    like this for port 2222:
-
-           VNC Host:Display:   localhost:0
-           Proxy/Gateway:      joe@far-away.east:2222
-
-    On Unix/MacOSX the username@ is not needed if it is the same as on
-    the client.  This will also work going to a different internal machine,
-    e.g. "joes-pc:0" instead of "localhost:0", as in the first example.
-
-
-    A Web or SOCKS proxy can also be used with SSH.  Use this if you are
-    inside a firewall that prohibits direct connections to remote SSH servers.
-
-           VNC Host:Display:   joe@far-away.east:0
-           Proxy/Gateway:      http://myproxy.west:8080
-
-    or for SOCKS:
-
-           VNC Host:Display:   joe@far-away.east:0
-           Proxy/Gateway:      socks://mysocks.west:1080
-
-    Use socks5://... to force the SOCKS5 version.  Note that the http://
-    prefix is REQUIRED for web proxies in SSH or SSH+SSL modes (but it is
-    the default proxy type in SSL mode.)
-
-    You can chain up to 3 proxies (any combination of http://, socks://
-    and ssh) by separating them with commas (i.e. first,second,third).
-
-    Note: the Web and/or SOCKS proxies must come before any SSH gateways.
-
-    For a non-standard SSH port and a Web or SOCKS proxy try:
-
-           VNC Host:Display:   localhost:0
-           Proxy/Gateway:      http://myproxy.west:8080,joe@far-away.east:2222
-
-    Even the "double SSH gateway" method (2 SSH encrypted legs) described
-    above works with an initial Web or SOCKS proxy, e.g.:
-
-           VNC Host:Display:   localhost:0
-           Proxy/Gateway:      socks://mysocks.west:1080,ssh.company.com,joes-pc
-

-
-    Some Notes on SSH localhost tunnelling with SSH options
-      NoHostAuthenticationForLocalhost=yes and UserKnownHostsFile=file:
-
-    Warning:  Note that for proxy use with ssh(1), tunnels going through
-    'localhost' are used.  This means ssh(1) thinks the remote hostname is
-    'localhost', which may cause collisions and confusion when storing
-    and checking SSH keys.
-
-    By default on Unix when a 'localhost' ssh host is involved the
-    ssh option -o NoHostAuthenticationForLocalhost=yes is applied (see
-    ssh_config(1) for details.)  This avoids the warnings and ssh refusing
-    to connect, but it reduces security.  A man in the middle attack may
-    be possible.  SSVNC prints out a warning in the terminal every time
-    the NoHostAuthenticationForLocalhost option is used.
-
-    On Unix to disable the use of NoHostAuthenticationForLocalhost set the env.
-    variable SSVNC_SSH_LOCALHOST_AUTH=1. This may induce extra ssh(1) dialogs.
-
-    On Unix a MUCH SAFER and more convenient way to proceed is to set the
-    known hosts option in Options -> Advanced -> 'Private SSH KnownHosts file'
-    Then, only for the host in the current profile, a private known_hosts
-    file will be used and so there will be no 'localhost' collisions.
-    This method is secure (assuming you verify the SSH key fingerprint)
-    and avoids the man in the middle attack.
-
-    On Windows, Putty/Plink is used and does not have the UserKnownHosts
-    or NoHostAuthenticationForLocalhost features.  Keys are stored in
-    the registry as localhost:port pairs and so it is possible to use the
-    'Port Slot' option to keep the keys separate to avoid the dialogs and
-    also maintain good security.
-
-    Note that for the "double SSH gateway" method the risk from using
-    NoHostAuthenticationForLocalhost is significantly less because the first
-    ssh connection does not use the option (it connects directly to the remote
-    host) and the second one is only exposed for the leg inside the first
-    gateway (but is still vulnerable there when NoHostAuthenticationForLocalhost
-    is used.)
-
-    As with a username that contains a space, use %SPACE (or %TAB) to
-    indicate it in the SSH proxies, e.g. john%SPACEsmith@ssh.company.com
-
- UltraVNC Proxies/Gateways:
-
-    UltraVNC has a "repeater" tool (http://www.uvnc.com/addons/repeater.html
-    and http://koti.mbnet.fi/jtko/) that acts as a VNC proxy.  SSVNC can
-    work with both mode I and mode II schemes of this repeater.
-
-    For Unix and MacOS X there is another re-implementation of the
-    UltraVNC repeater:
-
-        http://www.karlrunge.com/x11vnc/ultravnc_repeater.pl
-
-    So one does not need to run the repeater on a Windows machine.
-
-    Note that even though the UltraVNC repeater tool is NOT SSL enabled,
-    it can nevertheless act as a proxy for SSVNC SSL connections.
-    This is because, just as with a Web proxy, the proxy negotiations
-    occur before the SSL traffic starts.  (There is a separate UltraVNC
-    tool, repeater_SSL.exe, that is SSL enabled and is discussed below.)
-
-    Note: it seems only SSL SSVNC connections make sense with the
-    UltraVNC repeater.  SSH connections (previous section) do not seem to
-    and so are not enabled to (let us know if you find a way to use it.)
-
-    Unencrypted (aka Direct) SSVNC VNC connections (Vnc:// prefix in
-    'VNC Host:Display'; see Tip 5) also work with the UltraVNC repeater.
-
-    MODE I REPEATER:
-
-    For the mode I UltraVNC repeater the Viewer initiates the connection
-    and passes a string that is the VNC server's IP address (or hostname)
-    and port or display to the repeater (the repeater then makes the
-    connection to the server host and then exchanges data back and forth.)
-    To do this in SSVNC:
-
-           VNC Host:Display:   :0
-           Proxy/Gateway:      repeater://myuvncrep.west:5900+joes-pc:1
-
-    Where "myuvncrep.west" is running the UltraVNC repeater and 
-    "joes-pc:1" is the VNC server the repeater will connect us to.
-
-    Note here that the VNC Host:Display can be anything because it is
-    not used; we choose :0.  You cannot leave VNC Host:Display empty.
-
-    The Proxy/Gateway format is repeater://proxy:port+vncserver:display.
-    The string after the "+" sign is passed to the repeater server for
-    it to interpret (and so does not have to be the UltraVNC repeater;
-    you could create your own if you wanted to.)  For this example,
-    instead of joes-pc:1 it could be joes-pc:5901 or 192.168.1.4:1,
-    192.168.1.4:5901, etc.
-
-    If you do not supply a proxy port, then the default 5900 is assumed,
-    e.g. use repeater://myuvncrep.west+joes-pc:1 for port 5900 on
-    myuvncrep.west then connecting to port 5901 on joes-pc.
-
-    X11VNC: For mode I operation the VNC server x11vnc simply runs as
-    a normal SSL/VNC server:
-
-       x11vnc -ssl SAVE
-
-    because the repeater will connect to it as a VNC client would.
-    For mode II operation additional options are needed (see below.)
-
-
-    MODE II REPEATER:
-
-    For the mode II repeater both the VNC viewer and VNC server initiate
-    TCP connections to the repeater proxy.  In this case they pass a string
-    that identifies their mutual connection via "ID:NNNN", for example:
-
-           VNC Host:Display:   :0
-           Proxy/Gateway:      repeater://myuvncrep.west:5900+ID:2345
-
-    again, the default proxy port is 5900 if not supplied.  And we need
-    to supply a placeholder display ":0".
-
-    The fact that BOTH the VNC viewer and VNC server initiate outgoing
-    TCP connections to the repeater makes some things tricky, especially
-    for the SSL aspect.  In SSL one side takes the 'client' role and
-    the other side must take the 'server' role.  These roles must be
-    coordinated correctly or otherwise the SSL handshake will fail.
-
-    We now describe two scenarios: 1) SSVNC in Listening mode with STUNNEL
-    in 'SSL server' role; and 2) SSVNC in Forward mode with STUNNEL in
-    'SSL client' role.  For both cases we show how the corresponding
-    VNC server x11vnc would be run.
-
-    SSVNC Listening mode / STUNNEL 'SSL server' role:
-
-      By default, when using SSL over a reverse connection the x11vnc VNC
-      server will take the 'SSL client' role.  This way it can connect to a
-      standard STUNNEL (SSL server) redirecting connections to a VNC viewer
-      in Listen mode.  This is how SSVNC with SSL is normally intended to
-      be used for reverse connections (i.e. without the UltraVNC Repeater.)
-
-      To do it this way with the mode II UltraVNC Repeater; you set
-      Options -> Reverse VNC Connection, i.e. a "Listening Connection".
-      You should disable 'Verify All Certs' unless you have already
-      saved the VNC Server's certificate to Accepted Certs.  Or you can
-      set ServerCert to the saved certificate.  Then click 'Listen'.
-      In this case an outgoing connection is made to the UltraVNC
-      repeater, but everything else is as for a Reverse connection.
-
-      Note that in Listening SSL mode you must supply a MyCert or use the
-      "listen.pem" one you are prompted by SSVNC to create.
-
-      X11VNC command:
-
-        x11vnc -ssl -connect_or_exit repeater://myuvncrep.west+ID:2345
-
-
-    SSVNC Forward mode / STUNNEL 'SSL client' role:
-
-      x11vnc 0.9.10 and later can act in the 'SSL server' role for Reverse
-      connections (i.e. as it does for forward connections.)  Set these
-      x11vnc options: '-env X11VNC_DISABLE_SSL_CLIENT_MODE=1 -sslonly'
-
-      The -sslonly option is to prevent x11vnc from thinking the delay in
-      connection implies VeNCrypt instead of VNC over SSL.  With x11vnc
-      in X11VNC_DISABLE_SSL_CLIENT_MODE mode, you can then have SSVNC make
-      a regular forward connection to the UltraVNC repeater.
-
-      Note that SSVNC may attempt to do a 'Fetch Cert' action in forward
-      connection mode to either retrieve the certificate or probe for
-      VeNCrypt and/or ANONDH.  After that 'Fetch Cert' is done the
-      connection to the UltraVNC repeater will be dropped.  This is a
-      problem for the subsequent real VNC connection.  You can disable
-      'Verify All Certs' AND also set 'Do not Probe for VeNCrypt'
-      to avoid the 'Fetch Cert' action.  Or, perhaps better, add to
-      x11vnc command line '-connect_or_exit repeater://... -loop300,2'
-      (in addition to the options in the previous paragraphs.)  That way
-      x11vnc will reconnect once to the Repeater after the 'Fetch Cert'
-      action.  Then things should act pretty much as a normal forward
-      SSL connection.
-
-      X11VNC 0.9.10 command (split into two lines):
-
-        x11vnc -ssl -connect_or_exit repeater://myuvncrep.west+ID:2345 \ 
-             -env X11VNC_DISABLE_SSL_CLIENT_MODE=1 -loop300,2 -sslonly
-
-    We recommend using "SSVNC Forward mode / STUNNEL 'SSL client' role"
-    if you are connecting to x11vnc 0.9.10 or later.  Since this does
-    not use Listen mode it should be less error prone and less confusing
-    and more compatible with other features.  Be sure to use all of
-    the x11vnc options in the above command line.  To enable VeNCrypt,
-    replace '-sslonly' with '-vencrypt force'.  If you do not indicate
-    them explicitly to SSVNC, SSVNC may have to probe multiple times for
-    VeNCrypt and/or ANONDH.  So you may need '-loop300,4' on the x11vnc
-    cmdline so it will reconnect to the UltraVNC repeater 3 times.
-
-
-    Note that for UNENCRYPTED (i.e. direct) SSVNC connections (see vnc://
-    in Tip 5) using the UltraVNC Repeater mode II there is no need to
-    use a reverse "Listening connection" and so you might as well use
-    a forward connection.
-
-    For Listening connections, on Windows after the VNC connection you
-    MUST manually terminate the listening VNC Viewer (and connect again
-    if desired.)  Do this by going to the System Tray and terminating
-    the Listening VNC Viewer.  Subsequent connection attempts using the
-    repeater will fail unless you do this and restart the Listen.
-
-    On Unix and MacOS X after the VNC connection the UltraVNC repeater
-    proxy script will automatically restart and reconnect to the repeater
-    for another connection.  So you do not need to manually restart it.
-    To stop the listening, kill the listening VNC Viewer with Ctrl-C.
-
-    In the previous sections it was mentioned one can chain up to 3
-    proxies together by separating them with commas: proxy1,proxy2,proxy3.
-    Except where explicitly noted below this should work for "repeater://..."
-    as the final proxy.  E.g. you could use a web proxy to get out of a
-    firewall, and then connect to a remote repeater.
-
-    The UltraVNC SSL enabled repeater_SSL.exe is discussed below.
-
-
- UltraVNC Single Click:
-
-    UltraVNC has Single Click (SC) Windows VNC servers that allow naive
-    users to get them running very easily (a EXE download and a few
-    mouse clicks).  See http://sc.uvnc.com/ for details on how to create
-    these binaries.  Also there is a how-to here:
-    http://www.simply-postcode-lookup.com/SingleClickUltraVNC/SingleClickVNC.htm
-
-    The SC EXE is a VNC *server* that starts up a Reverse VNC connection
-    to a Listening Viewer (e.g. the viewer address/port/ID is hardwired
-    into the SC EXE).  So SC is not really a proxy, but it can be used
-    with UltraVNC repeater proxies and so we describe it here.
-
-    One important point for SC III binary creation: do NOT include 
-    "-id N" in the helpdesk.txt config file.  This is because the with
-    SSVNC the Ultra VNC repeater IS NOT USED (see below for how to
-    use it).  Use something like for helpdesk.txt:
-
-       [TITLE]
-       My UltraVNC SC III
-
-       [HOST]
-       Internet Support XYZ
-       -sslproxy -connect xx.xx.xx.xx:5500 -noregistry
-
-    (replace xx.xx.xx.xx with IP address or hostname of the SSVNC machine.)
-
-    The Unix SSVNC vncviewer supports the both the unencrypted "SC I"
-    mode and the SSL encrypted "SC III" mode.  For both cases SSVNC
-    must be run in Listening mode (Options -> Reverse VNC Connection)
-
-    For SC I, enable Reverse VNC Connection and put Vnc://0 (see Tip 5
-    below) in the VNC Host:Display to disable encryption (use a different
-    number if you are not using the default listening port 5500).
-    Then click on the "Listen" button and finally have the user run your
-    Single Click I EXE.
-
-    BTW, we used this for a SC I helpdesk.txt:
-
-       [TITLE]
-       My UltraVNC SC I
-
-       [HOST]
-       Internet Support XYZ
-       -connect xx.xx.xx.xx:5500 -noregistry
-
-    For SC III (SSL), enable Reverse VNC Connection and then UNSET "Verify
-    All Certs" (this is required).  Let the VNC Host:Display be ":0"
-    (use a different number if you are not using the default listening
-    port 5500).  Then click on the "Listen" button and finally have the
-    user run your Single Click III EXE.
-
-    Note that in Listening SSL mode you MUST supply a MyCert or use the 
-    "listen.pem" one you are prompted by SSVNC to create.
-
-
- UltraVNC repeater_SSL.exe proxy:
-
-    For repeater_SSL.exe SSL usage, with Single Click III or otherwise
-    (available at http://www.uvnc.com/pchelpware/SCIII/index.html)
-    it helps to realize that the ENTIRE connection is SSL encrypted,
-    even the proxy host:port/ID:NNNN negotiation, and so a different
-    approach needs to be taken from that described above in 'UltraVNC
-    Proxies/Gateways'.  In this case do something like this:
-
-           VNC Host:Display:   :0
-           Proxy/Gateway:      sslrepeater://myuvncrep.west:443+ID:2345
-
-    The sslrepeater:// part indicates the entire ID:XYZ negotiation must
-    occur inside the SSL tunnel.  Listening mode is not required in this
-    case: a forward VNC connection works fine (and is recommended).
-    As before, the ":0" is simply a placeholder and is not used.
-    Note that the UltraVNC repeater_SSL.exe listens on port 443 (HTTPS),
-    (it is not clear that it can be modified to use another port.)
-
-    Non-ID connections sslrepeater://myuvncrep.west:443+host:disp also
-    work, but the 2nd leg repeater <-> host:disp must be unencrypted.
-    The first leg SSVNC <-> repeater is, however, SSL encrypted.
-
-    sslrepeater:// only works on Unix or MacOSX using the provided
-    SSVNC vncviewer.  The modified viewer is needed; stock VNC viewers
-    will not work.  Also, proxy chaining (bouncing off of more than one
-    proxy) currently does not work for repeater_SSL.exe.
-
-
- VeNCrypt is treated as a proxy:
-
-    SSVNC supports the VeNCrypt VNC security type.  You will find out more
-    about this security type in the other parts of the Help documentation.
-    In short, it does a bit of plain-text VNC protocol negotiation before
-    switching to SSL/TLS encryption and authentication.
-
-    SSVNC implements its VeNCrypt support as final proxy in a chain
-    of proxies.  You don't need to know this or specify anything, but
-    it is good to know since it uses up one of the 3 proxies you are
-    allowed to chain together.  If you watch the command output you will
-    see the vencrypt:// proxy item.
-
-    You can specify that a VNC server uses VeNCrypt (Options -> Advanced)
-    or you can let SSVNC try to autodetect VeNCrypt.
-
-
- IPv6 can be treated as a proxy for UN-ENCRYPTED connections:
-
-    Read Tip 20 about SSVNC's IPv6 (128 bit IP addresses) support.
-    In short, because stunnel and ssh support IPv6 hostnames and
-    addresses, SSVNC does too without you needing to do anything.
-
-    However, in some rare usage modes you will need to specify the IPv6
-    server destination in the Proxy/Gateway entry box.  The only case
-    this appears to be needed is when making an un-encrypted connection
-    to an IPv6 VNC server.  In this case neither stunnel nor ssh are
-    used and you need to specify something like this:
-
-              VNC Host:Display:       localhost:0
-              Proxy/Gateway:          ipv6://2001:4860:b009::68:5900
-
-    and then select 'None' as the encryption type.  Note that the above
-    'localhost:0' setting can be anything; it is basically ignored.
-
-    Note that on Unix, MacOSX, and Windows un-encrypted ipv6 connections
-    are AUTODETECTED and so you likely NEVER need to supply ipv6://
-    Only try it if you encounter problems.  Also note that the ipv6://
-    proxy type does not work on Windows, so only the autodetection is
-    available there.
-
-    Note that if there is some other proxy, e.g. SOCKS or HTTP and that
-    proxy server is an IPv6 host (or will connect you to one) then any
-    sort of connection through that proxy will work OK: un-encrypted as
-    well as SSL or SSH connections, etc.
-
-    Unencrypted connection is the only special case where you may need
-    to specify an ipv6:// proxy.  If you find another use let us know.
-
-    See Tip 20 for more info.

-     20) IPv6 support.
-
-     1) To connect in SSH-Mode to a server running SSH on a non-standard
-        port (22 is the standard port) you need to use the Proxy/Gateway
-        setting.  The following is from the Proxies Help panel:
-
-        NON-STANDARD SSH PORT: To use a non-standard ssh port (i.e. a port other
-        than 22) you need to use the Proxy/Gateways as well.  E.g. something
-        like this for port 2222: 
-    
-               VNC Host:Display:   localhost:0
-               Proxy/Gateway:      joe@far-away.east:2222
-    
-        The username@ is not needed if it is the same as on the client.  This
-        will also work going to a different internal machine, e.g. "joes-pc:0"
-        instead of "localhost:0", as in the first example.
-    
-     2) Reverse VNC connections (Listening) are possible as well.
-        In this case the VNC Server initiates the connection to your
-        waiting (i.e. listening) SSVNC viewer.
-
-        Go to Options and select "Reverse VNC connection".  In the 'VNC
-        Host:Display' entry box put in the number (e.g. "0" or ":0", or
-        ":1", etc) that corresponds to the Listening display (0 -> port
-        5500, 1 -> port 5501, etc.) you want to use.  Then clicking on
-        'Listen' puts your SSVNC viewer in a "listening" state on that
-        port number, waiting for a connection from the VNC Server.
-
-        On Windows or using a 3rd party VNC Viewer multiple, simultaneous
-        reverse connections are always enabled.  On Unix/MacOSX with the
-        provided ssvncviewer they are disabled by default.  To enable them:
-        Options -> Advanced -> Unix ssvncviewer -> Multiple LISTEN Connections
-
-        Specify a specific interface, e.g. 192.168.1.1:0 to have stunnel
-        only listen on that interface.  IPv6 works too, e.g. :::0 or ::1:0
-        This also works for UN-encrypted reverse connections as well ('None').
-
-        See the Options Help for more info.
-
-     3) You can put global options in your ~/.ssvncrc file (ssvnc_rc on
-        Windows). Currently they are:
-
-	Put "mode=tsvnc" or "mode=sshvnc" in the ~/.ssvncrc file to have
-	the application start up in the given mode.
-
-        desktop_type=wmaker    (e.g.) to switch the default Desktop Type.
-
-        desktop_size=1280x1024 (e.g.) to switch the default Desktop Size.
-
-        desktop_depth=24       (e.g.) to switch the default Desktop Color Depth
-
-        xserver_type=Xdummy    (e.g.) to switch the default X Server Type.
-
-        (The above 4 settings apply only to the Terminal Services Mode.)
-
-        noenc=1  (same as the -noenc option for a 'No Encryption' option)
-        noenc=0  (do not show the 'No Encryption' option)
-
-        killstunnel=1 (same as -killstunnel), on Windows automatically kills
-        the STUNNEL process when the viewer exits.  Disable via killstunnel=0
-        and -nokillstunnel.
-
-        ipv6=0   act as though IPv6 was not detected.
-        ipv6=1   act as though IPv6 was detected.
-
-        cotvnc=1 have the default vncviewer on Mac OS X be the Chicken of
-        the VNC.  By default the included ssvnc X11 vncviewer is used
-        (requires Mac OS X X11 server to be running.)
-
-        mycert=file (same as -mycert file option).  Set your default MyCert
-        to "file".  If file does not exist ~/.vnc/certs/file is used.
-
-        cacert=file (same as -cacert file option).  Set your default ServerCert
-        to "file".  If file does not exist ~/.vnc/certs/file is used.  If
-        file is "CA" then ~/.vnc/certs/CA/cacert.pem is used.
-
-        crl=file (same as -crl file option).  Set your default CRL File
-        to "file".  If file does not exist ~/.vnc/certs/file is used.
-
-        Prefix any of these cert/key files with "FORCE:" to make them
-        immutable, e.g.  "cacert=FORCE:CA".
-
-        You can set any environment variable in ~/.ssvncrc by using a line
-        like env=VAR=value, for example:  env=SSVNC_FINISH_SLEEP=2
-
-        To change the fonts (see Tip 4 below for examples):
-
-        font_default=tk-font-name     (sets the font for menus and buttons)
-        font_fixed=tk-font-name       (sets the font for help text)
-
-     4) Fonts: To change the tk fonts, set these environment variables
-        before starting up ssvnc: SSVNC_FONT_DEFAULT and SSVNC_FONT_FIXED.
-        For example:
-
-            % env SSVNC_FONT_DEFAULT='helvetica -20 bold' ssvnc
-            % env SSVNC_FONT_FIXED='courier -14' ssvnc
-
-        or set both of them at once.  You can also set 'font_default' and
-        'font_fixed' in your ~/.ssvncrc.  E.g.:
-
-        font_default=helvetica -16 bold
-        font_fixed=courier -12
-
-     5) If you want to make a Direct VNC connection, WITH *NO* SSL OR
-        SSH ENCRYPTION or authentication, use the "vnc://" prefix in the
-        VNC Host:Display entry box, e.g. "vnc://far-away.east:0"  This
-        also works for reverse connections, e.g. vnc://0
-
-        Use Vnc:// (i.e. capital 'V') to avoid being prompted if you are
-        sure you want no encryption.  For example, "Vnc://far-away.east:0"
-        Shift+Ctrl-E in the entry box is a short-cut to add or remove
-        the prefix "Vnc://" from the host:disp string.
-
-        You can also run ssvnc with the '-noenc' cmdline option (now
-        the default) to have a check option 'None' that lets you turn off
-        Encryption (and profiles will store this setting).  Pressing Ctrl-E
-        on the main panel is a short-cut to toggle between the -noenc 'No
-        Encryption' mode and normal mode.  The option "Show 'No Encryption'
-        Option" under Options also toggles it.
-
-        The '-enc' option disables the button (and so makes it less obvious
-        to naive users how to disable encryption.)
-
-        Note as of SSVNC 1.0.25 the '-noenc' mode is now the default. I.e.
-        the 'No Encryption' option ('None') is shown by default.  When
-        you select 'None' you do not need to supply the "vnc://" prefix.
-        To disable the button supply the '-enc' cmdline option.
-
-        Setting SSVNC_DISABLE_ENCRYPTION_BUTTON=1 in your environment is
-        the same as -noenc.  You can also put noenc=1 in your ~/.ssvncrc file.
-
-        Setting SSVNC_DISABLE_ENCRYPTION_BUTTON=0 in your environment is
-        the same as -enc.  You can also put noenc=0 in your ~/.ssvncrc file.
-
-        Please be cautious/thoughtful when you make a VNC connection with
-        encryption disabled.  You may send sensitive information (e.g. a
-        password) over the network that can be sniffed.
-
-        It is also possible (although difficult) for someone to hijack an
-        existing unencrypted VNC session.
-
-        Often SSVNC is used to connect to x11vnc where the Unix username and
-        password is sent over the channel.  It would be a very bad idea to
-        let that data be sent over an unencrypted connection!  In general,
-        it is not wise to have a plaintext VNC connection.
-
-        Note that even the VNC Password challenge-response method (the password
-        is not sent in plaintext) leaves your VNC password susceptible to a
-        dictionary attack unless encryption is used to hide it.
-
-        So (well, before we made the button visible by default!) we forced
-        you to learn about and supply the "vnc://" or "Vnc://" prefix to
-        the host:port or use -noenc or the "Show 'No Encryption' Option"
-        to disable encryption.  This is a small hurdle, but maybe someone
-        will think twice.  It is a shame that VNC has been around for
-        over 10 years and still does not have built-in strong encryption.
-
-        Note the Vnc:// or vnc:// prefix will be stored in any profile that
-        you save so you do not have to enter it every time.
-
-        Set the env var SSVNC_NO_ENC_WARN=1 to skip the warning prompts the
-        same as the capitalized Vnc:// does.
-
-     6) Mobile USB memory stick / flash drive usage:  You can unpack
-        ssvnc to a flash drive for impromptu usage (e.g. from a friends
-        computer). 
-
-        If you create a directory "Home" in the toplevel ssvnc directory,
-        then that will be the default location for your VNC profiles
-        and certs.  So they follow the drive this way.  If you run like
-        this: "ssvnc ." or "ssvnc.exe ." the "Home" directory will be
-        created for you.
-
-        WARNING: if you use ssvnc from an "Internet Cafe", i.e. an
-        untrusted computer, an unscrupulous person may be capturing
-        keystrokes, etc.!
-
-	You can also set the SSVNC_HOME env. var. to point to any
-	directory you want. It can be set after starting ssvnc by putting
-	HOME=/path/to/dir in the Host:Display box and clicking "Connect".
-
-        For a Windows BAT file to get the "Home" directory correct
-        something like this might be needed:
-
-         cd \ssvnc\Windows
-         start \ssvnc\Windows\ssvnc.exe 
-
-     7) In the VNC Host:Display entry you can also use these "URL-like"
-        prefixes:
-
-           vncs://host:0, vncssl://host:0, vnc+ssl://host:0  for SSL
-
-        and
-
-           vncssh://host:0, vnc+ssh://host:0                 for SSH
-
-        There is no need to toggle the SSL/SSH setting.  These also work
-        from the command line, e.g.:  ssvnc vnc+ssh://mymachine:10
-
-     8) If you want this application to be SSH only, then supply the
-        command line option "-ssh" or set the env. var SSVNC_SSH_ONLY=1.
-
-        Then no GUI elements specific to SSL will appear (the
-        documentation wills still refer to the SSL mode, however).
-        To convert a running app to ssh-only select "Mode: SSH-Only"
-        in Options.
-
-        The wrapper scripts "sshvnc" and "sshvnc.bat" will start it up
-        automatically this way.
-
-        Or in your ~/.ssvncrc (or ~/ssvnc_rc on Windows) put "mode=sshvnc"
-        to have the tool always start up in that mode.
-
-     9) For an even simpler "Terminal Services" mode use "tsvnc" or
-        "tsvnc.bat" (or "-ts" option).  This mode automatically launches
-        x11vnc on the remote side to find or create your Desktop session
-        (usually the Xvfb X server).  So x11vnc must be available on the
-        remote server machines under "Terminal Services" mode.
-
-        From a full ssvnc you can press Ctrl-h to go into ssh-only mode
-        and Ctrl-t to toggle between "tsvnc" and "ssvnc" modes.  The
-        Options Mode menu also let you switch.
-
-        Or in your ~/.ssvncrc (or ~/ssvnc_rc on Windows) put "mode=tsvnc"
-        to have the tool always start up in that mode.
-
-    10) On Unix to get a 2nd GUI (e.g. for a 2nd connection) press Ctrl-N
-        on the GUI.  If only the xterm window is visible you can press
-        Ctrl-N or try Ctrl-LeftButton -> New SSVNC_GUI.  On Windows you
-        will have to manually Start a new one: Start -> Run ..., etc.
-
-    11) Pressing the "Load" button or pressing Ctrl-L or Clicking the Right
-        mouse button on the main GUI will invoke the Load dialog.
-
-        Pressing Ctrl-O on the main GUI will bring up the Options Panel.
-        Pressing Ctrl-A on the main GUI will bring up the Advanced Options.
-
-    12) If you use "SHELL" for the "Remote SSH Command" (or in the display
-        line: "user@hostname cmd=SHELL") then you get an SSH shell only:
-        no VNC viewer will be launched.  On Windows "PUTTY" will try
-        to use putty.exe (better terminal emulation than plink.exe).
-
-        A ShortCut for this is Ctrl-S with user@hostname in the entry box.
-
-    13) If you use "KNOCK" for the "Remote SSH Command" (or in the display
-        line "user@hostname cmd=KNOCK") then only the port-knocking is done.
-
-        A ShortCut for this is Ctrl-P with hostname the entry box.
-
-        If it is KNOCKF, i.e. an extra "F", then the port-knocking
-        "FINISH" sequence is sent, if any.  A ShortCut for this
-        Shift-Ctrl-P as long as hostname is present.
-
-    14) On Unix to have SSVNC act as a general STUNNEL redirector (i.e. no
-        VNC), put the desired host:port in VNC Host:Display (use a
-        negative port value if it is to be less than 200), then go to
-        Options -> Advanced -> Change VNC Viewer.  Change the "viewer"
-        command to be "xmessage OK" or "xmessage <port>" (or sleep) where
-        port is the desired local listening port.  Then click Connect.
-        If you didn't set the local port look for it in the terminal output.
-
-        On Windows set 'viewer' to "NOTEPAD" or similar; you can't
-        control the port though.  It is usually 5930, 5931, ... Watch
-        the messages or look at the stunnel log.
-
-    15) Tricks with environment variables:
-
-        You can change the X DISPLAY variable by typing DISPLAY=... into
-        VNC Host:Display and hitting Return or clicking Connect. Same
-        for HOME=.  On Mac, you can set DYLD_LIBRARY_PATH=... too.
-        It should propagate down the viewer.
-
-        Setting SLEEP=n increases the amount of time waited before
-        starting the viewer.  The env. var. SSVNC_EXTRA_SLEEP also does
-        this (and also Sleep: Option setting) Setting FINISH=n sets the
-        amount of time slept before the Terminal window exits on Unix
-        and MacOS X.  (same as SSVNC_FINISH_SLEEP env. var.)
-
-        Full list of parameters HOME/SSVNC_HOME, DISPLAY/SSVNC_DISPLAY
-        DYLD_LIBRARY_PATH/SSVNC_DYLD_LIBRARY_PATH, SLEEP/SSVNC_EXTRA_SLEEP
-        FINISH/SSVNC_FINISH_SLEEP, DEBUG_NETSTAT, REPEATER_FORCE,
-        SSH_ONLY, TS_ONLY, NO_DELETE, BAT_SLEEP, IPV6/SSVNC_IPV6=0 or 1.
-        See below for more info.  (the ones joined by "/" are equivalent
-        names, and the latter can be set as an env. var. as well.)
-
-        After you set the parameter, clear out the 'VNC Host:Display'
-        entry and replace it with the actual host and display number.
-
-        To replace the xterm terminal where most of the external commands
-        are run set SSVNC_XTERM_REPLACEMENT to a command that will run
-        a command in a terminal.  I.e.:  "$SSVNC_XTERM_REPLACEMENT cmd"
-        will run cmd.  If present, %GEOMETRY is expanded to a desired
-        +X+Y geometry.  If present, %TITLE is expanded to a desired title.
-        Examples: SSVNC_XTERM_REPLACEMENT='gnome-terminal -e'
-                  SSVNC_XTERM_REPLACEMENT='gnome-terminal -t "%TITLE" -e'
-                  SSVNC_XTERM_REPLACEMENT='konsole -e'
-
-        More info: EXTRA_SLEEP: seconds of extra sleep in scripts; 
-        FINISH_SLEEP: final extra sleep at end; DEBUG_NETSTAT put up a
-        window showing what netstat reports; NO_DELETE: do not delete tmp
-        bat files on Windows (for debugging); BAT_SLEEP: sleep this many
-        seconds at the end of each Windows bat file (for debugging.) 
-
-        You can also set any environment variable by entering in something
-        like ENV=VAR=VAL  e.g. ENV=SSH_AUTH_SOCK=/tmp/ssh-BF2297/agent.2297
-        Use an empty VAL to unset the variable.
-
-        There are also a HUGE number of env. vars. that apply to the Unix
-        and MacOS X wrapper script 'ss_vncviewer' and/or the ssvncviewer
-        binary.  See Options -> Advanced -> Unix ssvncviewer -> Help for
-        all of them.
-
-    16) On Unix you can make the "Open File" and "Save File" dialogs
-        bigger by setting the env. var. SSVNC_BIGGER_DIALOG=1 or
-        supplying the -bigger option.  If you set it to a Width x Height,
-        e.g. SSVNC_BIGGER_DIALOG=500x200, that size will be used.
-
-    17) On Unix / MacOSX to enable debug output you can set these env.
-        vars to 1: SSVNC_STUNNEL_DEBUG, SSVNC_VENCRYPT_DEBUG, and
-        SS_DEBUG (very verbose)
-
-    18) Dynamic VNC Server Port determination and redirection:  If you
-        are running SSVNC on Unix and are using SSH to start the remote
-        VNC server and the VNC server prints out the line "PORT=NNNN"
-        to indicate which dynamic port it is using (x11vnc does this),
-        then if you prefix the SSH command with "PORT=" SSVNC will watch
-        for the PORT=NNNN line and uses ssh's built in SOCKS proxy
-        (ssh -D ...) to connect to the dynamic VNC server port through
-        the SSH tunnel.  For example:
-
-                VNC Host:Display     user@somehost.com
-                Remote SSH Command:  PORT= x11vnc -find -nopw
-
-        or "PORT= x11vnc -display :0 -localhost", etc.  Or use "P= ..."
-
-        There is also code to detect the display of the regular Unix
-        vncserver(1).  It extracts the display (and hence port) from
-        the lines "New 'X' desktop is hostname:4" and also 
-        "VNC server is already running as :4".  So you can use
-        something like:
-
-                PORT= vncserver; sleep 15 
-        or:     PORT= vncserver :4; sleep 15 
-
-        the latter is preferred because when you reconnect with it will
-        find the already running one.  The former one will keep creating
-        new X sessions if called repeatedly.
-
-        On Windows if PORT= is supplied SOCKS proxying is not used, but
-        rather a high, random value of the VNC port is chosen (e.g. 8453)
-        and assumed to be free, and is passed to x11vnc's -rfbport option.
-        This only works with x11vnc (not vncserver).
-
-    19) On Unix if you are going to an older SSH server (e.g. Solaris 10),
-        you will probably need to set the env. var. SS_VNCVIEWER_NO_T=1
-        to disable the ssh "-t" option being used (that can prevent the
-        command from being run).
-
-    20) SSVNC is basically a wrapper for the stunnel and ssh programs,
-        and because those two programs have good IPv6 support SSVNC will
-        for most usage modes support it as well.  IPv6 is 128 bit internet
-        addresses (as opposed to IPv4 with its 32 bit xxx.yyy.zzz.nnn IPs.
-
-        So for basic SSL and SSH connections if you type in an IPv6 IP
-        address, e.g. '2001:4860:b009::68', or a hostname with only an
-        IPv6 lookup, e.g. ipv6.l.google.com, the connection will work
-        because stunnel and ssh handle these properly.
-
-        Note that you often need to supply a display number or port after
-        the address so put it, e.g. ':0' at the end: 2001:4860:b009::68:0
-        You can also use the standard notation [2001:4860:b009::68]:0
-        that is more clear.  You MUST specify the display if you use
-        the IPv6 address notation (but :0 is still the default for a
-        non-numeric hostname string.)
-
-        IPv4 addresses encoded in IPv6 notation also work, e.g.
-        ::ffff:192.168.1.100 should work for the most part.
-
-        SSVNC on Unix and MacOSX also has its own Proxy helper tool
-        (pproxy)  This script has been modified to handle IPv6 hostnames
-        and addresses as long as the IO::Socket::INET6 Perl module
-        is available.  On Windows the relay6.exe tool is used.
-
-        So for the most part IPv6 should work without you having to do
-        anything special.  However, for rare usage, the proxy helper tool
-        can also treat and IPv6 address as a special sort of 'proxy'.
-        So in the entry Proxy/Gateway you can include ipv6://host:port
-        and the IPv6 host will simply be connected to and the data
-        transferred.  In this usage mode, set the VNC Host:Display
-        to anything, e.g. 'localhost:0'; it is ignored if the ipv6://
-        endpoint is specified as a proxy.  Need for ipv6:// usage proxy
-        should be rare.
-
-        Note that for link local (not global) IPv6 addresses you may
-        need to include the network interface at the end of the address,
-        e.g. fe80::a00:20ff:fefd:53d4%eth0
-
-        Note that one can use a 3rd party VNC Viewer with SSVNC (see
-        Options -> Advanced -> Change VNC Viewer.)  IPv6 will work for
-        them as well even if they do not support IPv6.
-
-        IPv6 support on Unix, MacOSX, and Windows is essentially complete
-        for all types of connections (including proxied, unencrypted and
-        reverse connections.)  Let us know if you find a scenario that
-        does not work (see the known exception for putty/plink below.)
-
-        You can set ipv6=0 in your ssvncrc, then no special relaying for
-        IPv6 will be done (do this if there are problems or slowness in
-        trying to relay ipv6 and you know you will not connect to any
-        such hosts.)  Set ipv6=1 to force the special processing even if
-        IPv6 was not autodetected.  To change this dynamically, you also
-        enter IPV6=... in the VNC Host:Display entry box and press Enter.
-        Also on Unix or MacOSX you can set the env. var. SSVNC_IPV6=0
-        to disable the wrapper script from checking if hosts have ipv6
-        addresses (this is the same as setting ipv6=0 in ssvncrc or by
-        the setting ipv6 in the Entry box.)
-
-        On Windows plink.exe (SSH client) currently doesn't work for
-        IPv6 address strings (e.g. 2001:4860:b009::68) but it does work
-        for hostname strings that resolve to IPv6 addresses.
-
-        Note that one can make a home-brew SOCKS5 ipv4-to-ipv6 gateway
-        proxy using ssh like this:
-
-          ssh -D '*:1080' localhost "printf 'Press Enter to Exit: '; read x"
-  
-        then specify a proxy like socks5://hostname:1080 where hostname
-        is the machine running the above ssh command.  Add '-v' to the
-        ssh cmdline for verbose output.  See also the x11vnc inet6to4 tool
-        (a direct ipv4/6 relay, not socks.)

- SSVNC Escape Keys:
-
-   The Unix SSVNC VNC Viewer, ssvncviewer(1), has an 'Escape Keys'
-   mechanism that enables using keystrokes that are bound as 'Hot Keys'
-   to specific actions.
-
-   So, when you have all of the modifier keys ('escape keys') pressed down,
-   then subsequent keystrokes are interpreted as local special actions
-   instead of being sent to the remote VNC server.
-   
-   This enables quick parameter changing and also panning of the viewport.
-   E.g. the keystroke 'r' is mapped to refresh the screen.
-   
-   Enter 'default' in the entry box to enable this feature and to use the
-   default modifier list (Alt_L,Super_L on unix and Control_L,Meta_L on
-   macosx) or set it to a list of modifier keys, e.g. Alt_L,Control_L.
-   Note that _L means left side of keyboard and _R means right side.
-
-   Alt_L is the 'Alt' key on the left side of the keyboard, and Super_L
-   is usually the 'WindowsFlaggie(TM)' on the left side of the keyboard,
-   so when both of those are pressed, the escape keys mapping take effect.
-
-
-   Here is info from the ssvncviewer(1) manual page:
-
-     -escape str    This sets the 'Escape Keys' modifier sequence and enables
-                    escape keys mode.  When the modifier keys escape sequence
-                    is held down, the next keystroke is interpreted locally
-                    to perform a special action instead of being sent to the
-                    remote VNC server.
-
-                    Use '-escape default' for the default modifier sequence.
-                    (Unix: Alt_L,Super_L and MacOSX: Control_L,Meta_L)
-
-    Here are the 'Escape Keys: Help+Set' instructions from the Popup Menu:
-
-    Escape Keys:  Enter a comma separated list of modifier keys to be the
-    'escape sequence'.  When these keys are held down, the next keystroke is
-    interpreted locally to invoke a special action instead of being sent to
-    the remote VNC server.  In other words, a set of 'Hot Keys'.
-    
-    To enable or disable this, click on 'Escape Keys: Toggle' in the Popup.
-    
-    Here is the list of hot-key mappings to special actions:
-    
-       r: refresh desktop  b: toggle bell   c: toggle full-color
-       f: file transfer    x: x11cursor     z: toggle Tight/ZRLE
-       l: full screen      g: graball       e: escape keys dialog
-       s: scale dialog     +: scale up (=)  -: scale down (_)
-       t: text chat                         a: alphablend cursor
-       V: toggle viewonly  Q: quit viewer   1 2 3 4 5 6: UltraVNC scale 1/n
-    
-       Arrow keys:         pan the viewport about 10% for each keypress.
-       PageUp / PageDown:  pan the viewport by a screenful vertically.
-       Home   / End:       pan the viewport by a screenful horizontally.
-       KeyPad Arrow keys:  pan the viewport by 1 pixel for each keypress.
-       Dragging the Mouse with Button1 pressed also pans the viewport.
-       Clicking Mouse Button3 brings up the Popup Menu.
-    
-    The above mappings are *always* active in ViewOnly mode, unless you set the
-    Escape Keys value to 'never'.
-    
-    If the Escape Keys value below is set to 'default' then a default list of
-    of modifier keys is used.  For Unix it is: Alt_L,Super_L and for MacOSX it
-    is Control_L,Meta_L.  Note: the Super_L key usually has a Windows(TM) Flag
-    on it.  Also note the _L and _R mean the key is on the LEFT or RIGHT side
-    of the keyboard.
-    
-    On Unix   the default is Alt and Windows keys on Left side of keyboard.
-    On MacOSX the default is Control and Command keys on Left side of keyboard.
-    
-    Example: Press and hold the Alt and Windows keys on the LEFT side of the
-    keyboard and then press 'c' to toggle the full-color state.  Or press 't'
-    to toggle the ultravnc Text Chat window, etc.
-    
-    To use something besides the default, supply a comma separated list (or a
-    single one) from: Shift_L Shift_R Control_L Control_R Alt_L Alt_R Meta_L
-    Meta_R Super_L Super_R Hyper_L Hyper_R or Mode_switch.

- Description:
-
-    *** IMPORTANT ***: Only with SSL Certificate verification (either manually
-    or via a Certificate Authority certificate) can Man-In-The-Middle attacks be
-    prevented.  Otherwise, only passive network sniffing attacks are prevented.
-    There are hacker tools like dsniff/webmitm and cain that implement SSL
-    Man-In-The-Middle attacks.  They rely on the client user not bothering to
-    check the cert.
-
-    Some people may be confused by the above because they are familiar with
-    their Web Browser using SSL (i.e. https://... websites) and those sites
-    are authenticated securely without the user's need to verify anything
-    manually.  The reason why this happens automatically is because 1) their
-    web browser comes with a bundle of Certificate Authority certificates
-    and 2) the https sites have paid money to the Certificate Authorities to
-    have their website certificate signed by them.  When using SSL in VNC we
-    normally do not do something this sophisticated, and so we have to verify
-    the certificates manually.  However, it is possible to use Certificate
-    Authorities with SSVNC; that method is described below.
-
-    The SSL Certificate files described below may have been created externally
-    (e.g. by x11vnc or openssl): you can import them via "Import Certificate".
-    OR you can click on "Create Certificate ..." to use THIS program to generate
-    a Certificate + Private Key pair for you (in this case you will need to
-    distribute one of the generated files to the VNC Server).
-
-    Then you associate the Saved cert with the VNC server, see the panel entry
-    box description below.  Then click Connect.  You will usually want to Save
-    this association in a VNC Server profile for the next time you connect.
-
- Expiration:
-
-    SSL Certificates will Expire after a certain period (usually 1-2 years;
-    if you create a cert with this tool you can set it to any length you want).
-    So if for a particular Cert you find you can no longer connect, check the
-    STUNNEL log output to see if the cert has expired.  Then create and distribute
-    a new one.
-
- Fetch Cert:
-
-    You can also retrieve and view the VNC Server's Cert via the "Fetch Cert"
-    button on the main panel.  After you check that it is the correct Cert (e.g. by
-    comparing MD5 hash or other info), you can save it.  The file it was saved
-    as will be set as the "ServerCert" to verify against for the next connection.
-    To make this verification check permanent, you will need to save the profile
-    via 'Save'.
-
-    NOTE: See the CA section below for how "Fetch Cert/Verify All Certs" WILL NOT
-    WORK when a Certificate Authority (CA) is used (i.e. you need to save the CA's
-    cert instead.)  It will work if the certificate is Self-Signed.
-
- Verify All Certs:
-
-    If "Verify All Certs" is checked on the main panel, you are always forced
-    to check unrecognized server certs, and so the first time you connect to
-    a new server you may need to follow a few dialogs to inspect and save the
-    server certificate.
-
-    Under "Verify All Certs", new certificates are saved in the 'Accepted Certs'
-    directory.  When the checkbox is set all host profiles with "CertsDir" set to
-    "ACCEPTED_CERTS" (and an empty "ServerCert" setting) will be checked against
-    the pool of accepted certificates in the 'Accepted Certs' directory.
-
-    Note that we have "Verify All Certs" on by default so that users who do not
-    understand the SSL Man-In-The-Middle problem will not be left completely
-    vulnerable to it.  Everyone still must make the effort to verify new
-    certificates by an external method to be completely safe.
-
-    To have "Verify All Certs" toggled off at startup, use "ssvnc -nv" or set
-    SSVNC_NO_VERIFY_ALL=1 before starting.  If you do not even want to see the
-    button, use "ssvnc -nvb" or SSVNC_NO_VERIFY_ALL_BUTTON=1.
-
-    Note: "Fetch Cert" and "Verify All Certs" are currently not implemented in
-    "SSH + SSL" mode.  In this case to have server authentication "ServerCert"
-    must be set explicitly to a file (or "CertsDir" to a directory).
-
-    Also note that "Fetch Cert" only works in a limited fashion in "Listen"
-    mode (it is the VNC Server that initiates the connection), and so you
-    may need to be set via "ServerCert" as well.
-
-    NOTE: See the CA section below for how "Fetch Cert/Verify All Certs"
-    WILL NOT WORK when a Certificate Authority (CA) is used (i.e. you need
-    to save the CA's cert instead.)  The "Fetch Cert" saving method will
-    work if the certificate is Self-Signed.
-
- CA:
-
-    One can make SSL VNC server authentication more "automatic" as it is in
-    Web Browsers going to HTTPS sites, by using a Certificate Authority (CA)
-    cert (e.g. a professional one like Verisign or Thawte, or one your company
-    or organization creates) for the "ServerCert".  This is described in detail
-    here: http://www.karlrunge.com/x11vnc/ssl.html
-
-    CA's are not often used, but if the number of VNC Servers scales up it can
-    be very convenient because the viewers (i.e. SSVNC) only need the CA cert,
-    not all of the Server certs.
-
-    IMPORTANT NOTE: if a VNC Server is using a CA signed certificate instead
-    of its own Self-Signed one, then "Fetch Cert", etc. saving mechanism
-    WILL NOT WORK.  You must obtain the CA certificate and explicitly set
-    it as the ServerCert or import it to 'Accepted Certs'.
-
-
- Now what goes into the panel's entry boxes is described.
-
-
- Your Certificate + Key (MyCert):
-
-    You can specify YOUR own SSL certificate (PEM) file in "MyCert" in which
-    case it is used to authenticate YOU (the viewer) to the remote VNC Server.
-    If this fails the remote VNC Server will drop the connection.
-
-    So the Server could use this method to authenticate Viewers instead of the
-    more common practice of using a VNC password or x11vnc's -unixpw mode.
-
-
- Server Certificates (ServerCert/CertsDir):
-    
-    Server certs can be specified in one of two ways:
-    
-        - A single certificate (PEM) file for a single server
-          or a single Certificate Authority (CA)
-    
-        - A directory of certificate (PEM) files stored in
-          the special OpenSSL hash fashion.
-    
-    The former is set via "ServerCert" in this gui.
-    The latter is set via "CertsDir" in this gui.
-    
-    The former corresponds to the "CAfile" STUNNEL parameter.
-    The latter corresponds to the "CApath" STUNNEL parameter.
-
-    See stunnel(8) or stunnel.mirt.net for more information.
-    
-    If the remote VNC Server fails to authenticate itself with respect to the
-    specified certificate(s), then the VNC Viewer (your side) will drop the
-    connection.
-
-    Select which file or directory by clicking on the appropriate "Browse..."
-    button.  Once selected, if you click Info or the Right Mouse button on
-    "Browse..."  then information about the certificate will be displayed.
-
-    If, as is the default, "CertsDir" is set to the token "ACCEPTED_CERTS"
-    (and "ServerCert" is unset) then the certificates accumulated in the special
-    'Accepted Certs' directory will be used.  "ACCEPTED_CERTS" is the default for
-    every server ("Verify All Certs").  Note that if you ever need to clean this
-    directory, each cert is saved in two files, for example:
-
-          hostname-0=bf-d0-d6-9c-68-5a-fe-24-c6-60-ba-b4-14-e6-66-14.crt
-    and
-          9eb7c8be.0
-
-    This is because of the way OpenSSL must use hash-based filenames in Cert dirs. 
-    The file will have a "full filename:" line indicating the fingerprint and
-    hostname associated with it.  Be sure to remove both files.  The Delete Certs
-    dialog should automatically find the matching one for you and prompt you to
-    remove it as well.
-
- Certificate Revocation List (CRL File):
-
-    For large scale deployments, usually involving a CA Cert, it is worthwhile
-    to be able to revoke individual certs (so that a new CA cert does not need to
-    be created and new keys distributed).  Set CRL File to the path to the
-    file containing the revoked certificates (or a directory containing 
-    OpenSSL style hash-based filenames.)  See the x11vnc -sslCRL documentation
-    for how to create CRL's.  In short, the commands 'openssl ca -revoke ...'
-    and 'openssl ca -gencrl ...' are the ones to look for; See the ca(1) manpage.
-
- Create Certificate:
-
-    A simple dialog to create a Self-Signed Certificate.  See the x11vnc
-    -sslGenCA, -sslGenCert options for creating a CA Cert and signing with it.
-
- Import Certificate:
-
-    You can paste in a Certificate or read one in from a file to add to your
-    list of Server Certificates.  If (also) saved in the 'Accepted Certs'
-    directory, it will be automatically used to verify any Server when in
-    'Verify All Certs' Mode. 
-
- Deleting Certificates:
-
-    To delete a Certificate+private_key pair click on "Delete Certificate"
-    and select one in the menu.  You will be prompted to remove it,
-    and also any corresponding .pem or .crt file.  For "ACCEPTED_CERTS"
-    it will find the matching "HASH" file and prompt you to remove that too.
-
-
- Default Certs and Keys:
-
-    Use the "-mycert file" option (same as "-cert file") to set a default
-    MyCert.  The user will then have to manually clear the field to not
-    use a certificate.  This is the same as "mycert=file" (also "cert=file")
-    in the ~/.ssvncrc file.  If "file" does not exist, then ~/.vnc/certs is
-    prepended to it.
-
-    Use the "-cacert file" option (same as "-ca file") to set a default
-    ServerCert.  The user will then have to manually clear the field to not
-    set a server cert.  This is the same as "cacert=file" (also "ca=file")
-    in the ~/.ssvncrc file.  If "file" does not exist, then ~/.vnc/certs is
-    prepended to it.  Use "-cacert CA" to set it to ~/.vnc/certs/CA/cacert.pem
-
-    Use the "-crl file" option to set a default CRL File.  The user will
-    then have to manually clear the field to not use a CRL.  This is the
-    same as "crl=file" in the ~/.ssvncrc file.  If "file" does not exist,
-    then ~/.vnc/certs is prepended to it.
-
-    A sys-admin might set up an SSVNC deployment for user's workstations or
-    laptops using one or more of -cacert (authenticate VNC server to the
-    user) or -mycert (authenticate user to VNC server) or -crl (supply a
-    list of revoked certificates).  Prefix either one with "FORCE:" to make
-    the setting unchangable.
-
-
- Notes:
-
-    If "Use SSH" has been selected then SSL certs are disabled.
-
-    See the x11vnc and STUNNEL documentation for how to create and use PEM
-    certificate files:
-
-        http://www.karlrunge.com/x11vnc/faq.html#faq-ssl-tunnel-ext
-        http://www.karlrunge.com/x11vnc/ssl.html
-        http://stunnel.mirt.net
-
-    A common way to create and use a VNC Server certificate is:
-
-        x11vnc -ssl SAVE ...
-
-    and then copy the Server certificate to the local (viewer-side) machine.
-    x11vnc prints out to the screen the Server certificate it generates
-    (stored in ~/.vnc/certs/server.crt).  You can set "ServerCert" to it
-    directly or use the "Import Certificate" action to save it to a file.
-    Or use the "Fetch Cert" method to retrieve it (be sure to verify the
-    MD5 fingerprint, etc).
-
-    x11vnc also has command line utilities to create server, client, and CA
-    (Certificate Authority) certificates and sign with it. See the above URLs.

- Deselecting a checkbox will disable the feature (but settings from the
- Dialog are remembered).  Click on it again to re-enable.
-
-
- Desktop Type:
-
-    The default type of remote Desktop type is the "kde" (The K Desktop
-    Environment) You can choose a different type: gnome, failsafe,
-    twm, etc.
-
-    This setting will ONLY be used if the desktop needs to be created.
-    If an existing session of yours is found it will be used instead
-    (log out of that session if you want to create a new Desktop type
-    or see the Multiple Sessions option under Advanced).
-
- Desktop Size:
-
-    The default size of remote Desktop type is the "1280x1024" with a
-    Color depth of 16 bits per pixel (BPP).  Choose one of the standard
-    WxH values or enter a custom one (TBD).
-
-    This setting will ONLY be used if the desktop needs to be created.
-    If an existing session of yours is found it will be used instead
-    (log out of that session if you want to create a new Desktop size
-    or see the Multiple Sessions option under Advanced).
-
-    Some X servers, Xdummy or a real X server, will allow dynamic screen
-    size changing after the session has started via a GUI configuration
-    tool (or xrandr(1) from the command line).
-
- X Server Type:
-
-    The default type of remote X session is the "Xvfb" (X virtual frame
-    buffer) X server.  It is available on most systems.  To choose a
-    different type, select "Xdummy", "Xvnc", "Xvnc.redirect".
-
-    Xdummy is part of the x11vnc project and is a virtual X server with
-    some nice features, but it Linux only and requires root permission
-    to run.  One user put 'ALL ALL = NOPASSWD: /usr/local/bin/Xdummy*'
-    in his sudo(1) configuration (via visudo).
-
-    For Xvnc that server is started up, and x11vnc polls it in its
-    normal way.  Use Xvnc.redirect if you want x11vnc to find and/or
-    create the Xvnc session, but after that merely transfer packets back
-    and forth between VNC viewer and Xvnc (I.e. x11vnc does no polling
-    or VNC protocol).
-
-
- Enable Printing:
-
-    This sets up a SSH port redirection for you from your remote session
-    to your local print server.  The CUPS mechanism is used.  The local
-    print server can also be SMB/Windows.
-
- Enable Sound:
-
-    Not completely implemented yet.  A partially working ESD method
-    is provided.  It may change over to http://nas.sourceforge.net in
-    the future.  As with printing, it uses a SSH port redirection to a
-    server running locally.
-
- File Transfer:
-
-    x11vnc supports both the UltraVNC and TightVNC file transfer
-    extensions.  On Windows both viewers support their file transfer
-    protocol.  On Unix only the SSVNC VNC Viewer has filexfer support;
-    it supports the UltraVNC flavor via a Java helper program.
-
-    Choose the one you want based on VNC viewer you will use.
-    The defaults for the SSVNC viewer package are TightVNC on Windows
-    and UltraVNC on Unix.
-
- View Only:
-
-    Start the VNC Viewer in View-Only mode (it may be switched to full
-    access later in the session).
-
- Change VNC Viewer:
-
-    If you do not like the VNC Viewer bundled in the package, you can
-    indicate another one here.
-
- X11 viewer MacOSX:
-
-    On MacOSX try to use the bundled X11 vncviewer instead of the
-    Chicken of the VNC viewer; the Xquartz X server must be installed
-    (it is by default on 10.5.x) and the DISPLAY variable must be set
-    (see Tip 15 of SSVNC Help to do this manually.)
-
-
- Advanced Options:
-
- VNC Shared:
-
-    Normal use of this program, 'tsvnc', *ALREADY* allows simultaneous
-    shared access of the remote desktop:   You simply log in as many
-    times from as many different locations with 'tsvnc' as you like.
-
-    Select this option for the traditional VNC server shared mode of
-    operation using a single x11vnc server.  SSH access is still required.
-
- Multiple Sessions:
-
-    To enable one user to have more than one Terminal Services Desktop
-    X session on a single machine, this option lets you create Tags for
-    multiple ones (e.g. KDE_BIG, TWM_800x600)
-
- X Login Greeter:
-
-    If you have root (sudo(1)) permission on the remote machine,
-    you can have x11vnc try to connect to X displays that have nobody
-    logged in yet.  This is most likely the login greeter running on
-    the Physical console.  sudo(1) is used to run x11vnc with FD_XDM=1.
-
-    An initial ssh running 'sudo id' is performed to try to 'prime'
-    sudo so the 2nd one that starts x11vnc does not need a password.
-
-    Note that if someone is already logged into the console of the XDM
-    display you will see their X session.
-
- Other VNC Server:
-
-    The x11vnc program running on the remote machine can be instructed to
-    immediately redirect to some other (3rd party, e.g. Xvnc or vnc.so)
-    VNC server.
-
- Use unixpw:
-
-    This enables the x11vnc unixpw mode.  A Login: and Password: dialog
-    will be presented in the VNC Viewer for the user to provide any Unix
-    username and password whose session he wants to connect to.
-
-    This mode is useful if a shared terminal services user (e.g. 'tsuser')
-    is used for the SSH login part (say via the SSH authorized_keys
-    mechanism and all users share the same private SSH key for 'tsuser').
-
-    In normal usage the per-user SSH login should be the simplest and
-    sufficient, in which case the unixpw option should NOT be selected.
-
- Client 8bit Color:
-
-    Have the VNC Viewer request low color mode (8 bits per pixel) for
-    slow links.  This may be disabled or further tuned (e.g. 64 color
-    mode) in the viewer during the session.
-
- Client-Side Caching:
-
-    x11vnc has an experiment Client-Side caching scheme "-ncache n"
-    that can give nice speedups.  But there are some drawbacks
-    because the cache-region is visible and uses much RAM.
-    http://www.karlrunge.com/x11vnc/faq.html#faq-client-caching
-
- X11VNC Options:
-
-    If you are familiar with x11vnc, you can specify any of its features
-    that you would like enabled.
-
- SSVNC Mode:
-
-    Clicking on this button will return you to the full SSVNC Mode.
-
- Unix ssvncviewer:
-
-    Clicking on this button will popup a menu for setting options
-    of the Unix (and Mac OS X) provided SSVNC vncviewer.
-
-
- ~/.ssvncrc file:
-
-    You can put global options in your ~/.ssvncrc file (ssvnc_rc on
-    Windows). Currently they are:
-
-    Put "mode=tsvnc" or "mode=sshvnc" in the ~/.ssvncrc file to have
-    the application start up in the given mode.
-
-    desktop_type=wmaker  (e.g.) to switch the default Desktop Type.
-
-    desktop_size=1280x1024  (e.g.) to switch the default Desktop Size.
-
-    desktop_depth=24  (e.g.) to switch the default Desktop Color Depth.
-
-    xserver_type=Xdummy  (e.g.) to switch the default X Server Type.
-
-    (The above 4 settings apply only to the Terminal Services Mode.)
-
-    noenc=1  (same as the -noenc option for a 'No Encryption' option)
-    noenc=0  (do not show the 'No Encryption' option)
-
-    font_default=tk-font-name     (sets the font for menus and buttons)
-    font_fixed=tk-font-name       (sets the font for help text)

-set msg {
-  Use SSL:  The default, use SSL via STUNNEL (this requires SSL aware VNC
-            server, e.g. x11vnc -ssl SAVE ...)  See the description in the
-            main Help panel.
-
-  Use SSH:  Instead of using STUNNEL SSL, use ssh(1) for the encrypted
-            tunnel.  You must be able to log in via ssh to the remote host.
-
-            On Unix the cmdline ssh(1) program (it must already be installed)
-            will be run in an xterm for passphrase authentication, prompts
-            about RSA keys, etc.  On Windows the cmdline plink.exe program
-            will be launched in a Windows Console window. (Apologies for
-            the klunkiness..)
-
-            You can set the "VNC Host:Display" to "user@host:disp" to
-            indicate ssh should log in as "user" on "host".  NOTE: On
-            Windows you *MUST* always supply the "user@" part (due to a
-            plink deficiency). E.g.:
-
-                VNC Host:Display:    fred@far-away.east:0
-
-
-            Gateway:  If an intermediate gateway machine must be used
-            (e.g. to enter a firewall; the VNC Server is not running on it),
-            put it in the Proxy/Gateway entry, e.g.:
-
-                VNC Host:Display:    workstation:0
-                Proxy/Gateway:       user@gateway-host:port
-  
-            ssh is used to login to user@gateway-host and then a -L port
-            redirection is set up to go to workstation:0 from gateway-host.
-            ":port" is optional, use it if the gateway-host SSH port is
-            not the default value 22.
-
-            Chaining 2 ssh's:  One can also do a "double ssh", i.e. a
-            first SSH to the gateway login machine then a 2nd ssh to the
-            destination machine (presumably it is running the vnc server).
-
-            Unlike the above example, the "last leg" (gateway-host ->
-            workstation) is also encrypted by SSH this way.  Do this by
-            splitting the gateway in two with a comma, the part before it
-            is the first SSH:
-
-                VNC Host:Display: localhost:0
-                Proxy/Gateway:    user@gateway-host:port,user@workstation:port
-
-            Web and SOCKS proxies can also be used with SSH:
-
-                VNC Host:Display: user@workstation:0
-                Proxy/Gateway:    socks://socks.server:1080
-
-            See the "SSH Proxies/Gateways" in the Main Help document for full
-            details.
-
-
-            Remote Command:  In the "Remote SSH Command" entry you can to
-            indicate that a remote command to be run.  The default is
-            "sleep 15" to make sure port redirections get established. But you
-            can run anything else, for example, to run x11vnc on your X :0
-            workstation display:
-
-                x11vnc -display :0 -nopw
-
-
-            Windows SSH SERVER: if you are ssh'ing INTO Windows (e.g. CYGWIN
-            SSHD server) there may be no "sleep" command so put in something
-            like "ping localhost" or "ping -n 10 -w 1000 localhost" to 
-            set a short delay to let the port redir get established.
-
-
-            Trick:  If you use "SHELL" asl the "Remote SSH Command" then
-            you get an SSH shell only: no VNC viewer will be launched.
-            On Windows "PUTTY" will try to use putty.exe (better terminal
-            emulation than plink.exe)  A shortcut for this is Ctrl-S as
-            long as user@hostname is present in the "VNC Host:Display" box.
-
-
-  Use SSH + SSL:
-
-            Tunnel the SSL connection through a SSH tunnel.  Use this
-            if you want end-to-end SSL and must use a SSH gateway (e.g. to
-            enter a firewall) or if additional SSH port redirs are required
-            (CUPS, Sound, SMB tunnelling: See Advanced Options).
-
-            This is a RARELY used mode, but included in case the need arises.
-
-
-  No Encryption:
-
-            In '-noenc' mode, which is now the default, (Ctrl-E also toggles
-            this mode), use this to make a Direct connection to the VNC Server
-            with no encryption whatsoever.  (Be careful about passwords, etc.)
-
-            The -noenc mode is now the default since SSVNC 1.0.25, use
-            the '-enc' cmdline option to disable the button.
-
-
-  Automatically Find X Session:
-
-            When using SSH mode to connect, you can select this option.  It
-            simply sets the Remote SSH Command to:
-
-                 PORT= x11vnc -find -localhost
-
-            This requires that x11vnc is installed on the remote computer
-            and is available in $PATH for the ssh login.  The command
-            "x11vnc -find -localhost" command is run on the remote
-            machine.
-
-            The -find option causes x11vnc to try to find an existing X
-            session owned by the user (i.e. who you ssh in as).  If it
-            does it attaches to it; otherwise the x11vnc VNC server exits
-            immediately followed by your VNC Viewer.
-
-            The PORT= option just means to let x11vnc pick its own
-            VNC port and then connect to whatever it picked.  Use P=
-            for more debugging output.
-
-            The idea for this mode is you simply type 'username@workstation'
-            in the VNC Host:Display box, Select 'Options -> Automatically
-            Find X Session', and then click Connect.  The tsvnc mode is
-            similar (it runs x11vnc on the remote side with the intent
-            of automatically finding, or creating, your desktop).
-
-
-  Unix Username & Password:
-
-            This is only available on Unix and MacOSX and when using
-            the SSVNC enhanced TightVNC viewer (it has been modified to
-            do Unix logins).  It supports a login dialog with servers
-            doing something like x11vnc's "-unixpw" mode.  After any
-            regular VNC authentication takes place (VNC Password), then
-            it sends the Unix Username, a Return, the Unix Password and
-            a final Return.  This saves you from typing them into the
-            "login:" and "Password:" prompts in the viewer window.
-
-            Note that the x11vnc -unixpw login mode is external to the
-            VNC protocol, so you need to be sure the VNC server is in
-            this mode and will be waiting for the dialog.  Otherwise the
-            username and password will be typed directly into the desktop
-            application that happens to have the focus!
-
-            When you select this option "Unix Username:" and "Unix
-            Password:" entry boxes appear on the main panel where you can
-            type them in.  x11vnc has settings that can be specified after
-            a ":" in the Unix username; they may be used here as well.
-            (For example: username:3/4,nc for a smaller screen and -nocache)
-
-            If the Unix Username is not set when you click Connect, then
-            any SSH username@host is used.  Otherwise the environment
-            variable $USER or $LOGNAME and finally whoami(1) is used.
-
-            Also Note that the Unix Password is never saved in a VNC
-            profile (so you have to type it each time).  Also, the remote
-            x11vnc server is instructed to not echo the Username string
-            by sending an initial Escape.  Set the SSVNC_UNIXPW_NOESC=1
-            environment variable to override this.
-
-  Reverse VNC Connection:
-
-            Reverse (listening) VNC connections are possible as well.
-            Enable with this button "Reverse VNC Connection (-LISTEN)"
-
-            In this case the VNC Server initiates the connection to your
-            waiting (i.e. listening) SSVNC viewer.
-
-            For SSL connections in the 'VNC Host:Display' entry box put in
-            the number (e.g. "0" or ":0" or ":1", etc.) that corresponds to
-            the Listening display (0 -> port 5500, 1 -> port 5501, etc.) you
-            want to use.  For example x11vnc can then be used via:
-            "x11vnc ... -ssl SAVE -connect hostname:port" using the "port"
-            with the one you chose.
-
-            Clicking on the 'Listen' button puts your SSVNC viewer
-            in a "listening" state on that port number, waiting for a
-            connection from the VNC Server.
-
-            Then a VNC server should establish a reverse connection to
-            that port on this machine (e.g. -connect this-machine:5500
-            or -connect this-machine:5503, etc.)
-
-            Server SSL certificates will be verified, however you WILL
-            NOT be prompted about unrecognized ones; rather, you MUST
-            set up the correct Server certificate (e.g. by importing).
-            prior to any connections.
-
-            If the connection is failing in Reverse VNC (listening) mode,
-            check the STUNNEL log output to see if STUNNEL is unable to
-            authenticate the VNC Server.  If you want to allow in a
-            reverse connection with NO Server authentication, unset the
-            'Verify All Certs' option. 
-
-            When listening in SSL, you will ALSO need to specify YOUR
-            OWN SSL cert, "MyCert", or otherwise let the GUI prompt you
-            to create a "listen.pem" and use that.
-
-            The "listen.pem" will be reused in later SSL Listening
-            connections unless you specify a different one with MyCert.
-
-            On Windows or using a 3rd party VNC Viewer multiple,
-            simultaneous reverse connections are always enabled.
-            On Unix/MacOSX with the provided ssvncviewer they are disabled
-            by default.  To enable them:
-            Options -> Advanced -> Unix ssvncviewer -> Multiple LISTEN Conns.
-
-            For reverse connections in SSH or SSH + SSL modes it is a
-            little trickier.  The SSH tunnel (with -R tunnel) must be
-            established and remain up waiting for reverse connections.
-            The default time is "sleep 1800", i.e. 30 mins.  You can put
-            a longer or shorter sleep in "Remote SSH Command" (perhaps
-            after your command runs:  cmd; sleep 3600).
-
-            For SSH reverse connections put "hostname:n" in
-            'VNC Host:Display' or "user@hostname:n".  The "n" will be the
-            listening display on the *REMOTE* side.  So to have the remote
-            x11vnc connect use: "x11vnc ... -connect localhost:n" or
-            "x11vnc -R connect:localhost:n" (-ssl will be needed for SSH+SSL
-            mode).  If the -R port cannot be opened because it is in use
-            by another program you will have to kill everything and start
-            over using a different port.
-
-            In reverse connections mode be careful to protect the listening
-            VNC Viewer from direct connections (neither SSL nor SSH)
-            connecting directly to its listening port thereby bypassing
-            the tunnel.  This can be done by a host-level firewall that
-            only lets in, say, port 5500 (the default one ":0" for stunnel
-            to listen on).  Or for SSH reverse connections allow NO 5500+n
-            ports in.  For reverse connections, the Unix enhanced tightvnc
-            viewers supplied in the SSVNC package will only listen on
-            localhost so these precautions are not needed.
-
-            Specify a specific interface, e.g. 192.168.1.1:0 to have stunnel
-            only listen on that interface.  IPv6 works too, e.g. :::0 or ::1:0
-            Also works for UN-encrypted reverse connections as well ('None').
-
-            Note that for SSL connections use of "Proxy/Gateway" does not
-            make sense: the remote side cannot initiate its reverse connection
-            via the Proxy.
-
-            Note that for SSH or SSH+SSL connections use of "Proxy/Gateway"
-            does not make sense (the ssh cannot do a -R on a remote host:port),
-            unless it is a double proxy where the 2nd host is the machine with
-            the VNC server.
-
-
-  View Only:               Have VNC Viewer ignore mouse and keyboard input.
-  
-  Fullscreen:              Start the VNC Viewer in fullscreen mode.
-  
-  Raise On Beep:           Deiconify viewer when bell rings.
-  
-  Use 8bit color:          Request a very low-color pixel format.
-  
-  Do not use JPEG:         Do not use the jpeg aspect of the tight encoding.
-
-  Use X11 vncviewer on MacOSX:
-                           On MacOSX try to use the bundled X11 vncviewer
-                           instead of the Chicken of the VNC viewer;
-                           The Xquartz X server must be installed (it is by
-                           default on 10.5.x) and the DISPLAY variable must
-                           be set (see Tip 15 of Help to do this manually.)
-                           Put cotvnc=1 in ~/.ssvncrc to switch the default.
-
-  Kill Stunnel Automatically:
-                           On Windows, automatically try to kill the STUNNEL
-                           process when the VNC Viewer exits.  This is a
-                           global setting (not per-profile); it can be also
-                           set via either the -killstunnel cmdline option,
-                           or killstunnel=1 in ssvnc_rc.  To disable it supply
-                           -nokillstunnel or put killstunnel=0 in ssvnc_rc.
-                           As of 1/2009 this option is on by default.
-
-                           The main drawback to having STUNNEL automatically
-                           killed is that you will not be able to view its
-                           logfile.  If you are having trouble connecting via
-                           SSL, disable this option and double click on the
-                           dark green STUNNEL icon in the tray to view the log.
-
-
-  Compress Level/Quality:  Set TightVNC encoding parameters.
-
-
-  Putty PW:  On Windows only: use the supplied password for plink SSH
-             logins.  Unlike the other options the value is not saved
-             when 'Save' is performed.  This feature is useful when
-             options under "Advanced" are set that require TWO SSH's:
-             you just have to type the password once in this entry box.
-             The bundled pageant.exe and puttygen.exe programs can also
-             be used to avoid repeatedly entering passwords (note this
-             requires setting up and distributing SSH keys).  Start up
-             pageant.exe or puttygen.exe and read the instructions there.
-
-             Note, that there is a small exposure to someone seeing the
-             putty password on the plink command line.
-
-             Note that the Putty PW is not cleared if you load in a
-             new VNC profile.
-
-
-  Port Slot: On Windows ports cannot be selected or checked as easily as
-             on Unix.  So listening ports for ssh redirs, proxy tunnelling,
-             and etc. things are picked via finding a free "slot".
-             The slots run from 30 to 99 and are locked based on the
-             existence of a file with the slot number in it.  When the
-             connection is about to be made, a free slot is found and used
-             to work out some ports (e.g. 5930 for the local VNC port,
-             etc.)  This way simultaneous SSVNC connections can take place.
-
-             One drawback of this is that Putty/Plink stores SSH keys based
-             on hostname:port, and with a proxy tunnel the hostname is
-             "localhost".  So the Putty key store may have key collisions
-             for the localhost tunnels, and plink will prompt you to
-             resolve the conflict WRT a different SSH key being discovered.
-
-             To work around this to some degree you can select a unique
-             Port Slot (in the range 50-99) for a specific host.  Then the
-             ssh redir port to this host will never change and so the
-             Putty localhost:fixed-port key should remain valid.

-             (i.e. SSL and SSH), SSHVNC (i.e. SSH-Only), and Terminal
-             Services mode (TSVNC; uses x11vnc)
-
-             Note: You can put "mode=tsvnc" or "mode=sshvnc" in your
-             ~/.ssvncrc file (ssvnc_rc on Windows) to have the application
-             start up in the given mode.
-
-
-  Show 'No Encryption' Option:
-
-             Note: since SSVNC 1.0.25 the 'No Encryption' Option is
-             enabled by default.
-
-             Select this to display a button that disables both SSL and
-             SSH encryption.  This is the same as Ctrl+E.  This puts
-             a check item "None" on the main panel and also a "No
-             Encryption" check item in the "Options" panel.  If you
-             select this item, there will be NO encryption for the VNC
-             connection (use cautiously) See Tip 5) under Help for more
-             information about disabling encryption.
-
-
-  Buttons:
-                
-  Use Defaults:    Set all options to their defaults (i.e. unset).
-
-  Delete Profile:  Delete a saved profile.
-
-  Advanced:        Bring up the Advanced Options dialog.
-
-  Save and Load:
-
-             You can Save the current settings by clicking on Save
-             (.vnc file) and you can also read in a saved one with Load
-             Profile.  Use the Browse... button to select the filename
-             via the GUI.
-
-             Pressing Ctrl-L or Clicking the Right mouse button on the
-             main GUI will invoke the Load dialog.
-
-             Note: On Windows since the TightVNC Viewer will save its own
-             settings in the Registry, some unexpected behavior is possible
-             because the viewer is nearly always directed to the VNC host
-             "localhost:30".  E.g. if you specify "View Only" in this gui
-             once but not next time the Windows VNC Viewer may remember
-             the setting.  Unfortunately there is not a /noreg option for
-             the Viewer.

-  The displayed SSL Certificate has been retrieved from the VNC Server via the
-  "Fetch Cert" action.
-  
-  It has merely been downloaded via the SSL Protocol:
-
-         *** IT HAS NOT BEEN VERIFIED OR AUTHENTICATED IN ANY WAY ***
-  
-  So, in principle, it could be a fake certificate being inserted by a bad
-  person attempting to perform a Man-In-The-Middle attack on your SSL connection.
-  
-  If, however, by some external means you can verify the authenticity of this SSL
-  Certificate you can use it for your VNC SSL connection to the VNC server you
-  wish to connect to.  It will provide an authenticated and encrypted connection.
-  
-  You can verify the SSL Certificate by comparing the MD5 or SHA1 hash value
-  via a method/channel you know is safe (i.e. not also under control of a
-  Man-In-The-Middle attacker).  You could also check the text between the
-  -----BEGIN CERTIFICATE----- and -----END CERTIFICATE----- tags, etc.
-  
-  Once you are sure it is correct, you can press the Save button to save the
-  certificate to a file on the local machine for use when you connect via VNC
-  tunneled through SSL.  If you save it, then that file will be set as the
-  Certificate to verify the VNC server against.  You can see this in the dialog
-  started via the "Certs..." button on the main panel.
-  
-  NOTE: If you want to make Permanent the association of the saved SSL certificate
-  file with the VNC server host, you MUST save the setting as a profile for
-  loading later. To Save a Profile, click on Options -> Save Profile ...,
-  and choose a name for the profile and then click on Save.
-
-  If "Verify All Certs" is checked, then you are forced to check all new certs.
-  In this case the certs are saved in the 'Accepted Certs' directory against
-  which all servers will be checked unless "ServerCert" or "CertsDir" has been
-  set to something else.
-
-  To reload the profile at a later time, click on the "Load" button on the
-  main panel and then select the name and click "Open".  If you want to be
-  sure the certificate is still associated with the loaded in host, click on
-  "Certs..." button and make sure the "ServerCert" points to the desired SSL
-  filename.
-
-  See the Certs... Help for more information.  A sophisticated method can be set
-  up using a Certificate Authority key to verify never before seen certificates
-  (i.e. like your web browser does).

-    This dialog helps you to create a simple Self-Signed SSL certificate.  
-
-    On Unix the openssl(1) program must be installed and in $PATH.
-    On Windows, a copy of the openssl program is provided for convenience.
-
-    The resulting certificate files can be used for either:
-
-       1) authenticating yourself (VNC Viewer) to a VNC Server
-    or 2) your verifying the identity of a remote VNC Server.
-
-    In either case you will need to safely copy one of the generated key or
-    certificate files to the remote VNC Server and have the VNC Server use
-    it.  Or you could send it to the system administrator of the VNC Server.
-
-    For the purpose of description, assume that the filename selected in the
-    "Save to file" entry is "vnccert.pem".  That file will be generated
-    by this process and so will the "vnccert.crt" file.  "vnccert.pem"
-    contains both the Private Key and the Public Certificate.  "vnccert.crt"
-    only contains the Public Certificate.
-
-    For case 1) you would copy "vnccert.crt" to the VNC Server side and 
-    instruct the server to use it.  For x11vnc it would be for example:
-
-        x11vnc -sslverify /path/to/vnccert.crt -ssl SAVE ...
-
-    (it is also possible to handle many client certs at once in a directory,
-    see the -sslverify documentation).  Then you would use "vnccert.pem"
-    as the MyCert entry in the SSL Certificates dialog.
-
-    For case 2) you would copy "vnccert.pem" to the VNC Server side and 
-    instruct the server to use it.  For x11vnc it would be for example:
-
-        x11vnc -ssl /path/to/vnccert.pem
-
-    Then you would use "vnccert.crt" as the as the ServerCert entry in the
-    "SSL Certificates" dialog.
-
-
-    Creating the Certificate:
-    
-    Choose a output filename (ending in .pem) in the "Save to file" entry.
-
-    Then fill in the identification information (Country, State or Province,
-    etc).
-
-    The click on "Create" to generate the certificate files.
-
-    Encrypting the Private Key:  It is a very good idea to encrypt the
-    Private Key that goes in the "vnccert.pem".  The downside is that
-    whenever that key is used (e.g. starting up x11vnc using it) then
-    the passphrase will need to be created.  If you do not encrypt it and
-    somebody steals a copy of the "vnccert.pem" file then they can pretend
-    to be you.
-
-    After you have created the certificate files, you must copy and import
-    either "vnccert.pem" or "vnccert.pem" to the remote VNC Server and
-    also select the other file in the "SSL Certificates" dialog.
-    See the description above.
-
-    For more information see:
-
-           http://www.karlrunge.com/x11vnc/ssl.html
-           http://www.karlrunge.com/x11vnc/faq.html#faq-ssl-tunnel-int
-
-    The first one describes how to use x11vnc to create Certificate
-    Authority (CA) certificates in addition to Self-Signed ones.
-
-
-    Tip: if you choose the "Common Name" to be the internet hostname
-    (e.g. gateway.mydomain.com) that connections will be made to or
-    from that will avoid many dialogs when connecting mentioning that
-    the hostname does not match the Common Name.

-
-    Type 1) would be used to verify the identity of a remote VNC Server, whereas
-    type 2) would be used to authenticate ourselves to the remote VNC Server.
-
-    A type 1) by convention ends with file suffix ".crt" and looks like:
-
------BEGIN CERTIFICATE-----

-
-    First, either paste in the text or set the "Read from File" filename.

-    Next, set the "Save to File" name to the file where the imported certificate
-    will be saved.
-
-    Then, click on "Save" to save the imported Certificate.

-

-    the actual display screen.  You may need also to adjust your VNC Viewer
-    to not show this region (the SSVNC Unix viewer does it automatically).
-
-    The scheme uses a lot of RAM, but at least it has the advantage that

-    need to be modified, changing both the server and the viewer.
-

-    This method requires a working CUPS Desktop setup on the remote side
-    of the connection and working CUPS (or possibly Windows SMB or IPP)
-    printing on the local viewer-side of the connection.
-
-    For CUPS printing redirection to work properly, you MUST enable it for
-    the connection that *creates* your terminal services X session (i.e. the
-    first connection.)  You cannot retroactively enable CUPS redirection
-    on an already existing terminal services X session.  (See CUPS printing
-    for normal SSVNC mode for how you might do that.)
-
-    Enter the VNC Viewer side (i.e. where you are sitting) CUPS server
-    under "Local CUPS Server".  Use "localhost:631" if there is one
-    on your viewer machine (normally the case if you set up a printer
-    on your unix or macosx system), or, e.g., "my-print-srv:631" for a
-    nearby CUPS print server.  Note that 631 is the default CUPS port.
-
-    (On MacOSX it seems better to use "127.0.0.1" instead of "localhost".)
-
-    The SSVNC Terminal Services created remote Desktop session will have
-    the variables CUPS_SERVER and IPP_PORT set so all printing applications
-    will be redirected to your local CUPS server.  So your locally available
-    printers should appear in the remote print dialogs.
-
-
-    Windows/SMB Printers:  Under "Local SMB Print Server" you can set a
-    port redirection for a Windows (non-CUPS) SMB printer.  If localhost:139
-    does not work, try the literal string "IP:139", or use the known value
-    of the IP address manually.  139 is the default SMB port; nowadays 445
-    might be a better possibility.
-
-    For Windows/SMB Printers if there is no local CUPS print server, it is
-    usually a very good idea to make the CUPS Server setting EMPTY (to avoid
-    desktop apps trying incessantly to reach the nonexistent CUPS server.)
-
-    On the remote side, in the Desktop session the variables $SMB_SERVER,
-    $SMB_HOST, and $SMB_PORT will be set for you to use.
-
-    Unfortunately, printing to Windows may only ve partially functional due
-    to the general lack PostScript support on Windows.
-
-    If you have print admin permission on the remote machine you can
-    configure CUPS to know about your Windows printer via lpadmin(8) or
-    a GUI tool.  You give it the URI:
-
-        smb://localhost:port/printername
-
-    or possibly:
-
-        smb://localhost:port/computer/printername
-
-    "port" will be found in the $SMB_PORT.  You also need to identify
-    the printer type.  NOTE: You will leave "Local CUPS Server" blank in
-    this case.  The smbspool(1) command should also work as well, at least
-    for PostScript printers.
-
-    A similar thing can be done with CUPS printers if you are having problems
-    with the above default mechanism.  Use
-
-        http://localhost:port/printers/printername
-
-    For more info see: http://www.karlrunge.com/x11vnc/faq.html#faq-cups

-
-#    The "Manage 'ServerName' in .cups/client.conf for me" setting is usually
-#    NOT needed unless you are using Terminal Services to connect to an
-#    existing Session that did NOT have CUPS print redirection set at session
-#    start time (i.e. IPP_PORT and CUPS_SERVER were not set up).  In that
-#    case, select this option as a workaround: NOTE that the client.conf
-#    setting will REDIRECT ALL PRINTING for apps with the same $HOME/.cups
-#    directory (which you probably do not want), however it will be reset
-#    when the SSVNC viewer disconnects.

-    CUPS Printing requires SSH be used to set up the CUPS Print service TCP
-    port redirection.  This will be either of the "Use SSH" or "SSH+SSL" modes.
-    NOTE:  For pure SSL tunnelling it currently will not work.
-
-    This method requires working CUPS software setups on BOTH the remote
-    and local sides of the connection.
-
-    If the remote VNC server is Windows you probably cannot SSH into it
-    anyway...  If you can, you will still need to set up a special printer
-    TCP port redirection on your own.  Perhaps adding and configuring a
-    "Unix Printer" under Windows (like Method #2 below) will work.
-
-    If the local machine (SSVNC side) is Windows, see the bottom of this
-    help for redirecting to SMB printers.
-
-    If the remote VNC server is Mac OS X this method may or may not work.
-    Sometimes applications need to be restarted to get them to notice the
-    new printers.  Adding and configuring a special "Unix Printer",
-    (Method #2) below, might yield more reliable results at the cost of
-    additional setup and permissions.
-
-    For Unix/Linux remote VNC servers, applications may also need to be
-    restarted to notice the new printers.  The only case known to work
-    well is the one where the remote side has no CUPS printers configured.
-    As mentioned above, see Method #2 for another method.
-
-    *************************************************************************
-    *** Directions:
-
-    You choose your own remote CUPS redir port below under "Use Remote
-    CUPS Port".  6631 is our default and is used in the examples below.
-    Use it or some random value greater than 1024.  Note that the standard
-    CUPS server port is 631.
-
-    The port you choose must be unused on the VNC server machine (it is NOT
-    checked for you).  Print requests connecting to it are redirected to
-    your local VNC viewer-side CUPS server through the SSH tunnel.
-
-    (Note: root SSH login permission is needed for ports less than 1024,
-    e.g. 631; this is not recommended, use something around 6631 instead).
-
-    Then enter the VNC Viewer side (i.e. where you are sitting) CUPS server
-    into "Local CUPS Server".  A good choice is the default "localhost:631"
-    if there is a cups server on your viewer machine (this is usually the case
-    if you have set up a printer).  Otherwise enter, e.g., "my-print-srv:631"
-    for your nearby (viewer-side) CUPS print server.
-
-
-    The "Manage 'ServerName' in the $HOME/.cups/client.conf file for me"
-    setting below is enabled by default.  It should handle most situations.
-
-    What it does is modify the .cups/client.conf file on the VNC server-side
-    to redirect the print requests while the SSVNC viewer is connected.  When
-    SSVNC disconnects .cups/client.conf is restored to its previous setting.
-
-    If, for some reason, the SSVNC CUPS script fails to restore this file
-    after SSVNC disconnects, run this command on the remote machine:
-
-        cp $HOME/.cups/client.conf.back $HOME/.cups/client.conf
-
-    to regain your initial printing configuration.
-
-
-    You can also use CUPS on the VNC server-side to redirect to Windows
-    (SMB) printers.  See the additional info for Windows Printing at the
-    bottom of this help.
-
-
-    In case the default method (automatic .cups/client.conf modification)
-    fails, we describe below all of the possible methods that can be tried.
-
-    As noted above, you may need to restart applications for them to notice
-    the new printers or for them to revert to the original printers.  If this
-    is not acceptable, consider Method #2 below if you have the permission
-    and ability to alter the print queues for this.
-
-
-    *************************************************************************
-    *** Method #1:  Manually create or edit the file $HOME/.cups/client.conf
-    on the VNC server side by putting in something like this in it:
-
-    	ServerName localhost:6631
-
-    based on the port you set in this dialog's entry box.
-    
-    After the remote VNC Connection is finished, to go back to the non-SSH
-    tunnelled CUPS server and either remove the client.conf file or comment
-    out the ServerName line.  This restores the normal CUPS server for
-    you on the remote VNC server machine.
-
-    Select "Manage 'ServerName' in the $HOME/.cups/client.conf file for me"
-    to do this editing of the VNC server-side CUPS config file for you
-    automatically.  NOTE: It is now on by default (deselect it if you want
-    to manage the file manually; e.g. you print through the tunnel only very
-    rarely, or often print locally when the tunnel is up, etc.)
-
-    Select "Pass -env FD_CUPS=<Port> to x11vnc command line" if you are
-    starting x11vnc as the Remote SSH Command, and x11vnc is running in
-    -create mode (i.e. FINDCREATEDISPLAY).  That way, when your X session
-    is created IPP_PORT will be set correctly for the entire session.
-    This is the mode used for 'Terminal Services' printing.
-
-    NOTE: You probably would never select both of the above two options
-    at the same time, since they conflict with each other to some degree.
-
-
-    *************************************************************************
-    *** Method #2:  If you have admin permission on the VNC Server machine
-    you can likely "Add a Printer" via a GUI dialog, a Wizard, CUPS Web
-    interface (i.e. http://localhost:631/), lpadmin(8), etc.
-
-    You will need to tell the dialog that the network printer located
-    is at, e.g., localhost:6631, and anything else needed to identify
-    the printer (type, model, etc).  NOTE: sometimes it is best to set
-    the model/type as "Generic / Postscript Printer" to avoid problems
-    with garbage being printed out.
-
-    For the URI to use, we have successfully used ones like this with CUPS:
-
-       http://localhost:6631/printers/Deskjet-3840
-        ipp://localhost:6631/printers/Deskjet-3840
-
-    for an HP Deskjet-3840 printer.  See the CUPS documentation for more
-    about the URI syntax and pathname.
-
-    This mode makes the client.conf ServerName parameter unnecessary
-    (BE SURE TO DISABLE the "Manage 'ServerName' ... for me"  option.)
-
-
-    *************************************************************************
-    *** Method #3:  Restarting individual applications with the IPP_PORT
-    set will enable redirected printing for them, e.g.:
-
-       env IPP_PORT=6631 firefox
-
-    If you can only get this method to work, an extreme application would
-    be to run the whole desktop, e.g. "env IPP_PORT=6631 gnome-session", but
-    then you would need some sort of TCP redirector (ssh -L comes to mind),
-    to direct it to 631 when not connected remotely.
-
-
-    *************************************************************************
-    *** Windows/SMB Printers:  Under "Local SMB Print Server" you can set
-    a port redirection for a Windows (non-CUPS) SMB printer.  E.g. port
-    6632 -> localhost:139.
-
-    If localhost:139 does not work, try the literal string "IP:139", or
-    insert the actual IP address manually.  NOTE: Nowadays on Windows port
-    445 might be a better choice.
-
-    For Windows printers, if there is no local CUPS print server, set the
-    'Local CUPS Server' and 'Use Remote CUPS Port' to be EMPTY (to avoid
-    desktop apps trying incessantly to reach the nonexistent CUPS server.)
-
-    You must enable Sharing for your local Windows Printer.  Use Windows
-    Printer configuration dialogs to do this.
-
-    Next, you need to have sudo or print admin permission so that you can
-    configure the *remote* CUPS to know about this Windows printer via
-    lpadmin(8) or GUI Printer Configuration dialog, etc (Method #2 above).
-    You basically give it the URI:
-
-        smb://localhost:6632/printername
-
-    For example, we have had success with GNOME CUPS printing configuration
-    using:
-
-	smb://localhost:6632/HPOffice
-	smb://localhost:6632/COMPUTERNAME/HPOffice
-
-    where "HPOffice" was the name Windows shares the printer as.
-
-    Also with this SMB port redir mode, as a last resort you can often print
-    using the smbspool(8) program like this:
-
-       smbspool smb://localhost:6632/printer job user title 1 "" myfile.ps
-
-    You could put this in a script.  For this URI, it appears only the number
-    of copies ("1" above) and the file itself are important.
-
-    If on the local (SSVNC viewer) side there is some nearby CUPS print server
-    that knows about your Windows printer, you might have better luck with
-    that instead of using SMB.  Set 'Local CUPS Server' to it.

-    Often this means you want to run your ENTIRE remote desktop with ALL
-    applications instructed to use the sound daemon's network port.  E.g.
-
-        esddsp -s localhost:16001  startkde
-        esddsp -s localhost:16001  gnome-session
-
-    and similarly for artsdsp, etc.  You put this in your ~/.xession,
-    or other startup file.  This is non standard.  If you do not want to
-    do this you still can direct *individual* sound applications through
-    the tunnel, for example "esddsp -s localhost:16001 soundapp", where
-    "soundapp" is some application that makes noise (say xmms or mpg123).
-
-    Select "Pass -env FD_ESD=<Port> to x11vnc command line."  if you are
-    starting x11vnc as the Remote SSH Command, and x11vnc is running in
-    -create mode (i.e. FINDCREATEDISPLAY).  That way, your X session is
-    started via "esddsp -s ... <session>"  and the ESD variables will be
-    set correctly for the entire session.  (This mode make most sense for
-    a virtual, e.g. Xvfb or Xdummy session, not one a physical display).
-
-    Also, usually the remote Sound daemon must be killed BEFORE the SSH port
-    redir is established (because it is listening on the port we want to use
-    for the SSH redir), and, presumably, restarted when the VNC connection
-    finished.
-
-    One may also want to start and kill a local sound daemon that will
-    play the sound received over the network on the local machine.
-
-    You can indicate the remote and local Sound daemon commands below and
-    how they should be killed and/or restart.  Some examples:
-
-        esd -promiscuous -as 5 -port 16001 -tcp -bind 127.0.0.1
-        artsd -n -p 7265 -F 10 -S 4096 -n -s 5 -m artsmessage -l 3 -f
-
-    or you can leave some or all blank and kill/start them manually.
-
-    For convenience, a Windows port of ESD is provided in the util/esound
-    directory, and so this might work for a Local command:
-
-        esound\esd -promiscuous -as 5 -port 16001 -tcp -bind 127.0.0.1
-
-    NOTE: If you indicate "Remote Sound daemon: Kill at start." below,
-    then THERE WILL BE TWO SSH'S: THE FIRST ONE TO KILL THE DAEMON.
-    So you may need to supply TWO SSH PASSWORDS, unless you are using
-    something like ssh-agent(1), the Putty PW setting, etc.
-
-    You will also need to supply the remote and local sound ports for
-    the SSH redirs.  For esd the default port is 16001, but you can choose
-    another one if you prefer.
-
-    For "Local Sound Port" you can also supply "host:port" instead of just
-    a numerical port to specify non-localhost connections, e.g. to another
-    nearby machine.

-    Windows/Samba Filesystem mounting requires SSH be used to set up the SMB
-    service port redirection.  This will be either of the "Use SSH" or
-    "SSH+SSL" modes. NOTE: For pure SSL tunnelling it currently will not work.
-
-    This method requires a working Samba software setup on the remote
-    side of the connection (VNC server) and existing Samba or Windows file
-    server(s) on the local side (VNC viewer).
-
-    The smbmount(8) program MUST be installed on the remote side. This
-    evidently limits the mounting to Linux systems.  Let us know of similar
-    utilities on other Unixes.  Mounting onto remote Windows machines is
-    currently not supported (our SSH mode with services setup only works
-    to Unix).  On Debian and Ubuntu the smbmount program is currently in
-    the package named 'smbfs'.
-
-    Depending on how smbmount is configured you may be able to run it
-    as a regular user, or it may require running under su(1) or sudo(8)
-    (root password or user password required, respectively).  You select
-    which one you want via the checkbuttons below.
-
-    In addition to a possible su(1) or sudo(8) password, you may ALSO
-    need to supply passwords to mount each SMB share. This is an SMB passwd.
-    If it has no password just hit enter after the "Password:" prompt.
-
-    The passwords are supplied when the 1st SSH connection starts up;
-    be prepared to respond to them.
-
-    NOTE: USE OF SMB TUNNELLING MODE WILL REQUIRE TWO SSH'S, AND SO YOU
-    MAY NEED TO SUPPLY TWO LOGIN PASSWORDS UNLESS YOU ARE USING SOMETHING
-    LIKE ssh-agent(1) or the Putty PW setting.
-    %WIN
-
-    To indicate the Windows/Samba shares to mount enter them one per line
-    in one of the forms:
-
-      //machine1/share   ~/Desktop/my-mount1
-      //machine2/fubar   /var/tmp/my-foobar2  192.168.100.53:3456
-      1139  //machine3/baz  /var/tmp/baz      [...]
-
-    The first part is the standard SMB host and share name //hostname/dir
-    (note this share is on the local viewer-side not on the remote end).
-    A leading '#' will cause the entire line to be skipped.
-
-    The second part, e.g. /var/tmp/my-foobar2, is the directory to mount
-    the share on the remote (VNC Server) side.  You must be able to
-    write to this directory.  It will be created if it does not exist.
-    A leading character ~ will be expanded to $HOME.  So will the string
-    %HOME.  The string %USER will get expanded to the remote username.
-
-    An optional part like 192.168.100.53:3456 is used to specify the real
-    hostname or IP address, and possible non-standard port, on the local
-    side if for some reason the //hostname is not sufficient.
-
-    An optional leading numerical value, 1139 in the above example, indicates
-    which port to use on the Remote side to SSH redirect to the local side.
-    Otherwise a random one is tried (a unique one is needed for each SMB
-    server:port combination).  A fixed one is preferred: choose a free
-    remote port.
-
-    The standard SMB service ports (local side) are 445 and 139.  139 is
-    used by this application.
-
-    Sometimes "localhost" will not work on Windows machines for a share
-    hostname, and you will have to specify a different network interface
-    (e.g. the machine's IP address).  If you use the literal string "IP"
-    it will be attempted to replace it with the numerical IP address, e.g.:
-
-      //machine1/share   ~/Desktop/my-mount1   IP
-
-    VERY IMPORTANT: Before terminating the VNC Connection, make sure no
-    applications are using any of the SMB shares (or shells are cd-ed
-    into the share).  This way the shares will be automatically unmounted.
-    Otherwise you will need to log in again, stop processes from using
-    the share, become root and umount the shares manually ("smbumount
-    /path/to/share", etc.)

-    These Advanced Options that may require extra software installed on
-    the VNC server-side (the remote server machine) and/or on the VNC
-    client-side (where this gui is running).
-
-    The Service redirection options, CUPS, ESD/ARTSD, and SMB will
-    require that you use SSH for tunneling so that they can use the -R
-    port redirection will be enabled for each service.  I.e. "Use SSH"
-    or "SSH + SSL" mode.
-
-    These options may also require additional configuration to get them
-    to work properly.  Please submit bug reports if it appears it should
-    be working for your setup but is not.
-
-    Brief (and some not so brief) descriptions:
-
-      CUPS Print tunnelling:
-
-         Redirect localhost:6631 (say) on the VNC server to your local
-         CUPS server.  SSH mode is required.
-
-      ESD/ARTSD Audio tunnelling:
-
-         Redirect localhost:16001 (say) on the VNC server to your local
-         ESD, etc. sound server.  SSH mode is required.
-
-      SMB mount tunnelling:
-
-         Redirect localhost:1139 (say) on the VNC server and through that
-         mount SMB file shares from your local server.  The remote machine
-         must be Linux with smbmount installed. SSH mode is required.
-
-      Additional Port Redirs (via SSH):
-
-         Specify additional -L port:host:port and -R port:host:port
-         cmdline options for SSH to enable additional services.
-         SSH mode is required.
-
-      Automatically Find X Login/Greeter:
-
-         This mode is similar to "Automatically Find X Session" except
-         that it will attach to a X Login/Greeter screen that no one
-         has logged into yet.  It requires root privileges via sudo(1)
-         on the remote machine.  SSH mode is required.
-
-         As with "Automatically Find X Session" it works only with SSH
-         mode and requires x11vnc be installed on the remote computer.
-
-         It simply sets the Remote SSH Command to:
-
-              PORT= sudo x11vnc -find -localhost -env FD_XDM=1
-
-         An initial ssh running 'sudo id' is performed to try to
-         'prime' sudo so the 2nd one that runs x11vnc does not need
-         a password.  This may not always succeed... please mail us
-         the details if it doesn't.
-
-         See the 'X Login' description in 'Terminal Services' Mode
-         Help for more info.
-
-      Private SSH KnownHosts file:
-
-         On Unix in SSH mode, let the user specify a non-default
-         ssh known_hosts file to be used only by the current profile.
-         This is the UserKnownHostsFile ssh option and is described in the
-         ssh_config(1) man page.  This is useful to avoid proxy 'localhost'
-         SSH key collisions.
-
-         Normally one should simply let ssh use its default file
-         ~/.ssh/known_hosts for tracking SSH keys.  The only problem that
-         happens is when multiple SSVNC connections use localhost tunnel
-         port redirections.  These make ssh connect to 'localhost' on some
-         port (where the proxy is listening.)  Then the different keys
-         from the multiple ssh servers collide when ssh saves them under
-         'localhost' in ~/.ssh/known_hosts.
-
-         So if you are using a proxy with SSVNC or doing a "double SSH
-         gateway" your ssh will connect to a proxy port on localhost, and you
-         should set a private KnownHosts file for that connection profile.
-         This is secure and avoids man-in-the-middle attack (as long as
-         you actually verify the initial save of the SSH key!)
-
-         The default file location will be:
-
-                  ~/.vnc/ssh_known_hosts/profile-name.known
-
-         but you can choose any place you like.  It must of course be
-         unique and not shared with another ssh connection otherwise they
-         both may complain about the key for 'localhost' changing, etc.
-
-      SSH Local Port Protections:
-
-         An LD_PRELOAD hack to limit the number of SSH port redirections
-         to 1 and within the first 35 seconds.  So there is a smaller
-         window when the user can try to use your tunnel compared to
-         the duration of your session.  SSH mode is required.
-
-      STUNNEL Local Port Protections:
-
-         Try to prevent Untrusted Local Users (see the main Help panel)
-         from using your STUNNEL tunnel to connect to the remote VNC
-         Server.
-
-      Change VNC Viewer:
-
-         Specify a non-bundled VNC Viewer (e.g.  UltraVNC or RealVNC)
-         to run instead of the bundled TightVNC Viewer.
-
-      Port Knocking:
-
-         For "closed port" services, first "knock" on the firewall ports
-         in a certain way to open the door for SSH or SSL.  The port
-         can also be closed when the encrypted VNC connection finishes.
-
-      UltraVNC DSM Encryption Plugin:
-
-         On Unix only, by using the supplied tool, ultravnc_dsm_helper,
-         encrypted connections to UltraVNC servers using their plugins
-         is enabled.  Support for secret key encryption to Non-UltraVNC
-         DSM servers is also supported, e.g. x11vnc -enc blowfish:my.key
-
-      Do not Probe for VeNCrypt:
-
-         Disable VeNCrypt auto-detection probe when not needed.
-
-         By default in SSL mode an initial probe for the use of the
-         VeNCrypt or ANONTLS protocol is performed.  This is done
-         during the initial fetch-cert action.  Once auto-detected in
-         the initial probe, the real connection to the VNC Server will
-         use this information to switch to SSL/TLS at the right point in
-         the VeNCrypt/ANONTLS handshake.
-
-         In "Verify All Certs" mode initial the fetch-cert action is
-         required so the automatic probing for VeNCrypt is always done.
-         The fetch-cert is not needed if you specified a ServerCert or if
-         you disabled "Verify All Certs".  But by default the fetch-cert
-         is done anyway to try to auto-detect VeNCrypt/ANONTLS.
-
-         Set 'Do not Probe for VeNCrypt' to skip this unneeded fetch-cert
-         action (and hence speed up connecting.)  Use this if you
-         know the VNC Server uses normal SSL and not VeNCrypt/ANONTLS.
-
-         See also the next option, 'Server uses VeNCrypt SSL encryption'
-         to if you know it uses VeNCrypt/ANONTLS (the probing will also
-         be skipped if that option is set.)
-         
-      Server uses VeNCrypt SSL encryption:
-
-         Indicate that the VNC server uses the VeNCrypt extension to VNC;
-         it switches to an SSL/TLS tunnel at a certain point in the
-         VNC Handshake.  This is in constrast to the default ssvnc/x11vnc
-         SSL tunnel behavior where the *entire* VNC traffic goes through
-         SSL (i.e. it is vncs:// in the way https:// uses SSL)
-
-         Enable this option if you know the server supports VeNCrypt.
-         Also use this option for the older ANONTLS extension (vino).
-         Doing so will give the quickest and most reliable connection
-         to VeNCrypt/ANONTLS servers.  If set, any probing to try to
-         auto-detect VeNCrypt/ANONTLS will be skipped.
-
-         Some VNC servers supporting VeNCrypt: VeNCrypt, QEMU, ggi,
-         virt-manager, and Xen.  Vino supports ANONTLS.
-
-         The SSVNC VeNCrypt/ANONTLS support even works with 3rd party
-         VNC Viewers you specify via 'Change VNC Viewer' (e.g. RealVNC,
-         TightVNC, UltraVNC etc.) that do not directly support it.
-
-         Note: many VeNCrypt servers only support Anonymous Diffie Hellman
-         TLS which has NO built in authentication and you will also need
-         to set the option described in the next section.
-
-         If you are using VeNCrypt or ANONTLS for REVERSE connections
-         (Listen) then you *MUST* set this 'Server uses VeNCrypt SSL
-         encryption' option.   Note also that REVERSE connections using
-         VeNCrypt/ANONTLS currently do not work on Windows.
-
-         Also, if you are using the "Use SSH+SSL" double tunnel to a
-         VeNCrypt/ANONTLS server, you MUST set 'Server uses VeNCrypt
-         SSL encryption' because "Verify All Certs" is disabled in
-         SSH+SSL mode.
-
-      Server uses Anonymous Diffie-Hellman
-
-         Anonymous Diffie-Hellman can be used for SSL/TLS connections but
-         there are no Certificates for authentication.  Therefore only
-         passive eavesdropping attacks are prevented, not Man-In-The-Middle
-         attacks.  Not recommended; try to use verified X509 certs instead.
-
-         Enable this option if you know the server only supports Anon DH.
-         When you do so, remember that ALL Certificate checking will be
-         skipped (even if you have 'Verify All Certs' selected or set
-         a ServerCert.)
-
-         SSVNC may be able to autodetect Anon DH even if you haven't
-         selected 'Server uses Anonymous Diffie-Hellman'. Once detected, it
-         will prompt you whether it should continue.  Set the 'Server uses
-         Anonymous Diffie-Hellman' option to avoid trying autodetection
-         (i.e. forcing the issue.)
-
-         Note that most Anonymous Diffie-Hellman VNC Servers do so
-         via the VeNCrypt or ANONTLS VNC extensions (see the previous
-         section.)  For these servers if you select 'Server uses Anonymous
-         Diffie-Hellman' you *MUST* ALSO select 'Server uses VeNCrypt SSL
-         encryption', otherwise SSVNC may have no chance to auto-detect
-         the VeNCrypt/ANONTLS protocol.
-
-         Also note, if you are using the "Use SSH+SSL" double tunnel to
-         a VeNCrypt/ANONTLS server using Anon DH you MUST set 'Server
-         uses Anonymous Diffie-Hellman' because "Verify All Certs"
-         is disabled in SSH+SSL mode.
-
-      Include:
-
-       Default settings and Include Templates:
-
-         Before explaining how Include works, first note that if you
-         do not prefer some of SSVNC's default settings you can start
-         up SSVNC and then change the settings for the options that you
-         want to have a different default value.  Then type "defaults"
-         in VNC Host:Display entry box and press "Save" to save them in
-         the "defaults.vnc" profile.  After this, SSVNC will initialize
-         all of the default values and then apply your override values
-         in "defaults".
-
-         For example, suppose you always want to use a different, 3rd
-         party VNC Viewer.  Set Options -> Advanced -> Change VNC Viewer
-         to what you want, and then save it as the "defaults" profile.
-         Now that default setting will apply to all profiles, and SSVNC
-         in its startup state.
-
-         To edit the defaults Load it, make changes, and then Save it.
-         Delete the "defaults" profile to go back to no modifications.
-         Note that defaults created and saved while defaults.vnc existed
-         will NOT be automatically adjusted.
-
-       Include Templates:
-
-         Now suppose you have a certain class of settings that you do
-         not want to always be applied, but you want them to apply to a
-         group of profiles.
-
-         For example, suppose you have some settings for very low
-         bandwidth connections (e.g. low color modes and/or aggressive
-         compression and quality settings.)  Set these values in SSVNC
-         and then in the VNC Host:Display entry box type in, say,
-         "slowlink" and then press Save.  This will save those settings
-         in the template profile named "slowlink.vnc".
-
-         Now to create a real profile that uses this template type the
-         host:disp in "VNC Host:Display" and in Options -> Advanced
-         -> Includes type in "slowlink".  Then press Save to save the
-         host profile.  Then re-Load it.  The "slowlink" settings will
-         be applied after the defaults.  Make any other changes to the
-         setting for this profile and Save it again.  Next time you load
-         it in, the Include template settings will override the defaults
-         and then the profile itself is read in.
-
-         You may supply a comma or space separated list of templates
-         to include.  They are applied in the order listed.  They can be
-         full path names or basenames relative to the profiles directory.
-         You do not need to supply the .vnc suffix.  The non-default
-         settings in them will be applied first, and then any values in
-         the loaded Profile will override them.
-
-      Sleep:
-
-         Enter a number to indicate how many extra seconds to sleep
-         while waiting for the VNC viewer to start up.  On Windows this
-         can give extra time to enter the Putty/Plink password, etc.
-
-      Putty Args:
-
-         Windows only, supply a string to be added to all plink.exe
-         and putty.exe commands.  Example: -i C:\mykey.ppk
-
-      Launch Putty Pagent:
-
-         Windows only, launch the Putty key agent tool (pageant) to hold
-         your SSH private keys for automatic logging in by putty/plink.
-
-      Launch Putty Key-Gen:
-
-         Windows only, launch the Putty key generation tool (puttygen)
-         to create new SSH private keys.
-
-      Unix ssvncviewer:
-
-         Display a popup menu with options that apply to the special 
-         Unix SSVNC VNC Viewer (perhaps called 'ssvncviewer') provided by
-         this SSVNC package.  This only applies to Unix or Mac OS X.
-     
-      Use ssh-agent:
-
-         On Unix only: restart the GUI in the presence of ssh-agent(1)
-         (e.g. in case you forgot to start your agent before starting
-         this GUI).  An xterm will be used to enter passphrases, etc.
-         This can avoid repeatedly entering passphrases for the SSH logins
-         (note this requires setting up and distributing SSH keys).
-
-
-    About the CheckButtons:
-
-         Ahem, Well...., yes quite a klunky UI: you have to toggle the
-         CheckButton to pull up the Dialog box a 2nd, etc. time... don't
-         worry your settings will still be there!

-	set msg {
-    These Unix SSVNC VNC Viewer Options apply only on Unix or Mac OS X
-    when using the viewer (ssvncviewer) supplied by this SSVNC package.
-
-    Brief descriptions:
-
-      Multiple LISTEN Connections:
-
-         Allow multiple VNC servers to reverse connect at the same time
-         and so display each of their desktops on your screen at the
-         same time.
-
-      Listen Once:
-
-         Try to have the VNC Viewer exit after the first listening
-         connection. (It may not always be detected; use Ctrl-C to exit)
-
-      Listen Accept Popup Dialog:
-
-         In -listen (reverse connection listening) mode when a reverse
-         VNC connection comes in show a popup asking whether to Accept
-         or Reject the connection. (-acceptpopup vncviewer option.)
-
-      Accept Popup UltraVNC Single Click:
-
-         As in 'Listen Accept Popup Dialog', except assume the remote
-         VNC server is UltraVNC Single Click and force the execution of
-         the protocol to retrieve the extra remote-side info (Windows
-         User, ComputerName, etc) which is then also displayed in the
-         Popup window. (-acceptpopupsc vncviewer option.)
-
-      Use X11 Cursor:
-
-         When drawing the mouse cursor shape locally, use an X11 cursor
-         instead of drawing it directly into the framebuffer.  This
-         can sometimes give better response, and avoid problems under
-         'Scaling'. 
-
-      Disable Bell:
-
-         Disable beeps coming from remote side.
-
-      Use Raw Local:
-
-         Use the VNC Raw encoding for 'localhost' connections (instead
-         of assuming there is a local tunnel, SSL or SSH, going to the
-         remote machine.
-
-      Avoid Using Terminal:
-
-         By default the Unix ssvncviewer will prompt for usernames,
-         passwords, etc. in the terminal it is running inside of.
-         Set this option to use windows for messages and prompting as
-         much as possible.  Messages will also go to the terminal, but
-         all prompts will be done via popup window.
-
-         Note that stunnel(1) may prompt for a passphrase to unlock a
-         private SSL key.  This is fairly rare because it is usually
-         for Client-side SSL authentication.  stunnel will prompt from
-         the terminal; there seems to be no way around this.
-
-         Also, note that ssh(1) may prompt for an ssh key passphrase
-         or Unix password.  This can be avoided in a number of ways,
-         the simplest one is to use ssh-agent(1) and ssh-add(1).
-         However ssh(1) may also prompt you to accept a new public key
-         for a host or warn you if the key has changed, etc. 
-
-      Use Popup Fix:
-
-         Enable a fix that warps the popup (F8) to the mouse pointer.
-
-      Use XGrabServer (for fullscreen):
-
-         On Unix only, use the XGrabServer workaround for older window
-         managers.  Sometimes also needed on recent (2008) GNOME.  This
-         workaround can make going into/out-of Fullscreen work better.
-
-      Cursor Alphablending:
-
-         Use the x11vnc alpha hack for translucent cursors (requires Unix,
-         32bpp and same endianness)
-
-      TurboVNC:
-
-         If available on your platform, use a ssvncviewer compiled with
-         TurboVNC support.  This is based on the VirtualGL project:
-         http://www.sourceforge.net/projects/virtualgl	You will need
-         to install the VirtualGL's TurboJPEG library too.
-
-         Currently (May/2009) only Linux.i686, Linux.x86_64, and
-         Darwin.i386 have vncviewer.turbovnc binaries shipped in the
-         ssvnc bundles.  See the build instructions for how you might
-         compile your own.
-
-      Disable Pipelined Updates:
-
-         Disable the TurboVNC-like pipelined updates mode.  Pipelined
-         updates is the default even when not TurboVNC enabled.  They
-         ask for the next screen update before the current one has 
-         finished downloading, and so this might reduce the slowdown
-         due to high latency or low bandwidth by 2X or so.  Disable
-         them if they cause problems with the remote VNC Server or
-         use too much bandwidth.
-
-      Send CLIPBOARD not PRIMARY:
-
-         When sending locally selected text to the VNC server side,
-         send the CLIPBOARD selection instead of the PRIMARY selection.
-
-      Send Selection Every time:
-
-         Send selected text to the VNC server side every time the mouse
-         focus enters the main VNC Viewer window instead only when it
-         appears to have changed since the last send.
-
-      Scaling:
-
-         Use viewer-side (i.e. local) scaling of the VNC screen.  Supply
-         a fraction, e.g. 0.75 or 3/4, or a WxH geometry, e.g. 1280x1024,
-         or the string 'fit' to fill the current screen.  Use 'auto'
-         to scale the desktop to match the viewer window size.
-
-         If you observe mouse trail painting errors try using X11 Cursor.
-
-         Note that since the local scaling is done in software it can
-         be slow.  Since ZRLE is better than Tight in this regard, when
-         scaling is detected, the encoding will be switched to ZRLE.
-         Use the Popup to go back to Tight if you want to, or set the
-         env. var. SSVNC_PRESERVE_ENCODING=1 to disable the switch.
-
-         For additional speedups under local scaling: try having a solid
-         desktop background on the remote side (either manually or using
-         'x11vnc -solid ...'); and also consider using client side caching
-         'x11vnc -ncache 10 ...' if the remote server is x11vnc.
-
-      Escape Keys:
-
-         Enable 'Escape Keys', a set of modifier keys that, if all are
-         pressed down, enable local Hot Key actions.  Set to 'default'
-         to use the default (Alt_L,Super_L on unix, Control_L,Meta_L
-         on macosx) or set to a list of modifier keys.
-
-      Y Crop:
-
-         This is for x11vnc's -ncache client side caching scheme with our
-         Unix TightVNC viewer.  Sets the Y value to "crop" the viewer
-         size at (below the cut is the pixel cache region you do not
-         want to see).  If the screen is tall (H > 2*W) ycropping will
-         be autodetected, or you can set to -1 to force autodection.
-         Otherwise, set it to the desired Y value.  You can also set
-         the scrollbar width (very thin by default) by appending ",sb=N"
-         (or use ",sb=N" by itself to just set the scrollbar width).
-
-      ScrollBar Width:
-
-         This is for x11vnc's -ncache client side caching scheme with our
-         Unix TightVNC viewer.  For Y-Crop mode, set the size of the
-         scrollbars (often one want it to be very narrow, e.g. 2 pixels
-         to be less distracting.
-
-      RFB Version:
-
-         Set the numerical version of RFB (VNC) protocol to pretend to
-         be, 3.x.  Usually only needed with UltraVNC servers.
-
-      Encodings:
-
-         List encodings in preferred order, for example
-         'copyrect zrle tight'   The list of encodings is:
-         copyrect tight zrle zywrle hextile zlib corre rre raw
-
-      Extra Options:
-
-         String of extra Unix ssvncviewer command line options.  I.e. for
-         ones like -16bpp that cannot be set inside this SSVNC GUI.  For a
-         list click Help then 'SSVNC vncviewer -help Output'. 
-
-
-    These are environment variables one may set to affect the options
-    of the SSVNC vncviewer and also the ss_vncviewer wrapper script
-    (and hence may apply to 3rd party vncviewers too)

-    access to the remote VNC machine.
-
-    On Unix, for STUNNEL SSL tunnels we provide two options as extra
-    safeguards against untrusted local users.  Both only apply to Unix/MacOSX.
-    Note that Both options are *IGNORED* in reverse connection (Listen) mode.
-
-    1) The first one 'Use stunnel EXEC mode' (it is mutually exclusive with
-       option 2).  For this case the modified SSVNC Unix viewer must be
-       used: it execs the stunnel program instead of connecting to it via
-       TCP/IP.  Thus there is no localhost listening port involved at all.
-
-       This is the best solution for SSL stunnel tunnels, it works well and
-       is currently enabled by default.  Disable it if there are problems.
-
-    2) The second one 'Use stunnel IDENT check', uses the stunnel(8)
-       'ident = username' to use the local identd daemon (IDENT RFC 1413
-       http://www.ietf.org/rfc/rfc1413.txt) to check that the locally
-       connecting program (the SSVNC vncviewer) is being run by your userid.
-       See the stunnel(8) man page for details.
-
-       Normally the IDENT check service cannot be trusted much when used
-       *remotely* (the remote host may be have installed a modified daemon).
-       However when using the IDENT check service *locally* it should be
-       reliable.  If not, it means the local machine (where you run SSVNC)
-       has already been root compromised and you have a serious problem.
-
-       Enabling 'Use stunnel IDENT check' requires a working identd on the
-       local machine.  Often it is not installed or enabled (because it is not
-       deemed to be useful, etc).  identd is usually run out of the inetd(8)
-       super-server.  Even when installed and running it is often configured
-       incorrectly.  On a Debian/lenny system we actually found that the
-       kernel module 'tcp_diag' needed to be loaded! ('modprobe tcp_diag')

-    Some SSL implementations are incomplete or buggy or do not work properly
-    with other implementations.  SSVNC uses STUNNEL for its SSL encryption,
-    and STUNNEL uses the OpenSSL SSL implementation.
-
-    This causes some problems with non-OpenSSL implementations on the VNC server
-    side.  The most noticable one is the UltraVNC Single Click III (SSL) server:
-
-       http://www.uvnc.com/pchelpware/SCIII/index.html
-
-    It can make a reverse connection to SSVNC via an encrypted SSL tunnel.
-
-    Unfortunately, in the default operation with STUNNEL the connection will be
-    dropped after 2-15 minutes due to an unexpected packet.
-
-    Because of this, by default SSVNC will enable some SSL workarounds to make
-    connections like these work.  This is the STUNNEL 'options = ALL' setting:
-    it enables a basic set of SSL workarounds.
-
-    You can read all about these workarounds in the stunnel(8) manpage and the
-    OpenSSL SSL_CTX_set_options(3) manpage.
-
-    Why are we mentioning this?  STUNNELS's 'options = ALL' lowers the SSL
-    security a little bit.  If you know you do not have an incompatible SSL
-    implementation on the server side (e.g. any one using OpenSSL is compatible,
-    x11vnc in particular), then you can regain that little bit of security by
-    selecting the "Disable SSL Workarounds" option.
-
-    "Disable All SSL Workarounds" selected below will do that.  On the other hand,
-    choose "Keep the DONT_INSERT_EMPTY_FRAGMENTS Workaround" to retain that one,
-    commonly needed workaround.
-
-    BTW, you can set the environment variable STUNNEL_EXTRA_OPTS_USER to add
-    any lines to the STUNNEL global config that you want to.  See the stunnel(8)

-    On Unix and MacOSX with the provided SSVNC vncviewer, you can connect to an
-    UltraVNC server that is using one of its DSM encryption plugins: MSRC4, ARC4,
-    AESV2, and SecureVNC. More info at: http://www.uvnc.com/features/encryption.html
-
-    IMPORTANT: The UltraVNC DSM MSRC4, ARC4, and AESV2 implementations contain
-    unfixed errors that could allow an eavesdropper to recover the session
-    key or traffic easily.  They often do not provide strong encryption, but
-    only provide basic obscurity instead.  Do not use them with critical data.
-    The newer SecureVNC Plugin does not suffer from these problems.
-
-    See the bottom of this help text for how to use symmetric encryption with
-    Non-UltraVNC servers (for example, x11vnc 0.9.5 or later).  This mode does not
-    suffer the shortcomings of the UltraVNC MSRC4, ARC4, and AESV2 implementations.
-
-    You will need to specify the corresponding UltraVNC encryption key (created
-    by you using an UltraVNC server or viewer).  It is usually called 'rc4.key'
-    (for MSRC4), 'arc4.key' (for ARC4), and 'aesv2.key' (for AESV2).  Specify the
-    path to it or Browse for it.  Also, specify which type of plugin it is (or use
-    'guess' to have it guess via the before mentioned filenames).
-
-    The choice "UVNC SC" enables a special workaround for use with UltraVNC Single
-    Click and the MSRC4 plugin.  It may not be needed on recent SC (e.g. from
-    ~2009 and later; select "MSRC4" for these newer ones.)
-
-    You can also specify pw=my-password instead of a keyfile.  Use single quotes
-    pw='....' if the password contains shell meta-characters `!$&*(){}[]|;<>?
-
-    Use the literal string 'pw=VNCPASSWD' to have the VNC password that you
-    entered into the 'VNC Password:' be used for the pw=...
-
-    SSL and SSH tunnels do not apply in this mode (any settings are ignored.)
-
-    Proxying works in this mode, as well as Reverse Connections (Listen)
-
-    The choice "SecureVNC" refers to the SecureVNC Plugin using 128 bit AES or
-    ARC4 with 2048 bit RSA key exchange described here:
-
-          http://adamwalling.com/SecureVNC
-
-    Note in its default mode SecureVNC is *Vulnerable* to Man-In-The-Middle attacks
-    (encryption but no server authentication) so do not use it with critical data.
-    In SecureVNC mode you do not need to supply a 'Ultra DSM Keyfile'.  However,
-    if you DO supply a keyfile filename (recommended) if that file does not exist
-    you will be prompted if you want to save the UltraVNC server's RSA key in it.
-    The key's MD5 checksum is displayed so that you can verify that the key is
-    trusted.  One way to print out the SecureVNC public key MD5 checksum is:
-
-    openssl rsa -inform DER -outform DER -pubout -in ./Server_SecureVNC.pkey | dd bs=1 skip=24 | md5sum
-
-    Then on subsequent connections, if you continue to specify this filename, the
-    SecureVNCPlugin server's RSA key will be checked against the file's contents
-    and if they differ the connection will be dropped.
-
-    NOTE, However, if the SecureVNC keyfile ends in the string 'ClientAuth.pkey'
-    then its contents are used for SecureVNC's normal Client Authentication dialog
-    (you need to use Windows SecureVNCPlugin to generate this file on the server
-    side, it is usually called "Viewer_ClientAuth.pkey", and then safely copy it
-    to the viewer side.)  If you want to do BOTH Client Auth and server RSA key
-    storing (recommended), have the keyfile end in 'ClientAuth.pkey.rsa'; that way
-    the file will be used for storing the server RSA key and then the '.rsa' is
-    trimmed off and the remainder used for the SecureVNC Client Auth data filename.
-
-    Note that despite its intentions, Client Authentication in the FIRST release of
-    SecureVNC is still susceptible to Man-In-The-Middle attacks.  Even when that
-    is fixed, SecureVNC Client Authentication is still susceptible to "spoofing"
-    attacks where the viewer user may be tricked into revealing his VNC or MS-Logon
-    password if his connection is intercepted.  It is recommended you verify and
-    save the Server key (see above) in addition to using Client Authentication.
-
-    UltraVNC DSM encryption modes are currently experimental because unfortunately
-    the UltraVNC DSM plugin also modifies the RFB protocol(!), and so the SSVNC
-    vncviewer had to be modified to support it.  The tight, zlib, and some minor
-    encodings currently do not work in this mode and are disabled.
-
-    Note that this mode also requires the utility tool named 'ultravnc_dsm_helper'
-    that should be included in your SSVNC kit.
-
-    Select 'Non-Ultra DSM' to use symmetric encryption to a Non-UltraVNC server via
-    a supported symmetric key cipher.  x11vnc supports symmetric encryption via,
-    e.g., "x11vnc -enc aesv2:./my.key".  Extra ciphers are enabled for this mode
-    (e.g. blowfish and 3des).  'UVNC SC' and SecureVNC do not apply in this mode.
-
-    Note for the Non-Ultra DSM case it will also work with any VNC Viewer
-    (i.e. selected by Options -> Advanced -> Change VNC Viewer) not only the
-    supplied SSVNC vncviewer.
-
-    For experts: You can also set the random salt size and initialization vector
-    size in Salt,IV for example "8,16".  See the x11vnc and 'ultravnc_dsm_helper
-    -help' documentation for more info on this.

-         ssh_config(1) man page.  This is useful to avoid proxy 'localhost'
-         SSH key collisions.
-
-         Normally one should simply let ssh use its default file
-         ~/.ssh/known_hosts for tracking SSH keys.  The only problem with
-         that happens when multiple SSVNC connections use localhost tunnel
-         port redirections.  These make ssh connect to 'localhost' on some
-         port (where the proxy is listening.)  Then the different keys
-         from the multiple ssh servers collide when ssh saves them under
-         'localhost' in ~/.ssh/known_hosts.
-
-         So if you are using a proxy with SSVNC or doing a "double SSH
-         gateway" your ssh will connect to a proxy port on localhost, and you
-         should set a private KnownHosts file for that connection profile.
-         This is secure and avoids man-in-the-middle attack (as long as
-         you actually verify the initial save of the SSH key!)
-
-         The default file location will be:
-
-                  ~/.vnc/ssh_known_hosts/profile-name.known
-
-         but you can choose any place you like.  It must of course be
-         unique and not shared with another ssh connection otherwise they
-         both may complain about the key for 'localhost' changing, etc.

-    On Unix, for SSH tunnels we have an LD_PRELOAD hack (lim_accept.so)

-    Set this option to allow SSVNC (when in LISTEN / Reverse connections
-    mode) to allow multiple VNC servers to connect at the same time and
-    so display each of their desktops on your screen at the same time.
-
-    This option only applies on Unix or MaOSX when using the supplied
-    SSVNC vncviewer.  If you specify your own VNC Viewer it has no effect.
-
-    On Windows (only the stock TightVNC viewer is provided) it has no effect
-    because the Windows SSVNC can ONLY do "Multiple LISTEN Connections". 
-    Similarly on MacOSX if the COTVNC viewer is used there is no effect.
-
-    Rationale:  To play it safe, the Unix vncviewer provided by SSVNC
-    (ssvncviewer) only allows one LISTEN reverse connection at a time.
-    This is to prohibit malicious people on the network from depositing
-    as many desktops on your screen as he likes, even if you are already
-    connected to VNC server you desire.
-
-    For example, perhaps the malicious user could trick you into typing
-    a password into the desktop he displays on your screen.
-
-    This protection is not perfect, because the malicious user could
-    try to reverse connect to you before the correct VNC server reverse
-    connects to you.  This is even more of a problem if you keep your
-    SSVNC viewer in LISTEN mode but unconnected for long periods of time.
-    Pay careful attention in this case if you are to supplying sensitive
-    information to the remote desktop.
-
-    Enable 'Multiple LISTEN Connections' if you want to disable the default
-    protection in the Unix SSVNC vncviewer; i.e. allow multiple reverse
-    connections simultaneously (all vnc viewers we know of do this by default)
-
-    For more control, do not select 'Multiple LISTEN Connections', but
-    rather set the env. var SSVNC_MULTIPLE_LISTEN=MAX:n to limit the number
-    of simultaneous reverse connections to "n"

-    On Unix, some Window managers and some Desktops make it difficult for the
-    SSVNC Unix VNC viewer to go into full screen mode (F9) and/or return.
-
-    Sometimes one can go into full screen mode, but then your keystrokes or
-    Mouse actions do not get through.  This can leave you trapped because you
-    cannot inject input (F9 again) to get out of full screen mode.  (Tip:
-    press Ctrl-Alt-F2 for a console login shell; then kill your vncviewer
-    process, e.g. pkill vncviewer; then Alt-F7 to get back to your desktop)
-
-    We have seen this in some very old Window managers (e.g. fvwm2 circa
-    1998) and some very new Desktops (e.g. GNOME circa 2008).  We try
-    to work around the problem on recent desktops by using the NEW_WM
-    interface, but if you use Fullscreen, you may need to use this option.
-
-    The default for the SSVNC Unix VNC viewer is '-grabkbd' mode where it will
-    try to exclusively grab the keyboard.  This often works correctly.
-
-    However if Fullscreen is not working properly, try setting this
-    'Use XGrabServer' option to enable '-graball' mode where it tries to grab
-    the entire X server.  This usually works, but can be a bit flakey.
-
-    Sometimes toggling F9 a few times gets lets the vncviewer fill the whole
-    screen.  Sometimes tapping F9 very quickly gets it to snap in.  If GNOME
-    (or whatever desktop) is still showing its taskbars, it is recommended
-    you toggle F9 until it isn't. Otherwise, it is not clear who gets the input.
-
-    Best of luck.

- Description:
-
-    Port Knocking is where a network connection to a service is not provided
-    to just any client, but rather only to those that immediately prior to
-    connecting send a more or less secret pattern of connections to other
-    ports on the firewall.
-
-    Somewhat like "knocking" on the door with the correct sequence before it
-    being opened (but not necessarily letting you in yet).  It is also possible
-    to have a single encrypted packet (e.g. UDP) payload communicate with the
-    firewall instead of knocking on a sequence of ports.
-
-    Only after the correct sequence of ports is observed by the firewall does
-    it allow the IP address of the client to attempt to connect to the service.
-
-    So, for example, instead of allowing any host on the internet to connect
-    to your SSH service and then try to login with a username and password, the
-    client first must "tickle" your firewall with the correct sequence of ports.
-    Only then will it be allowed to connect to your SSH service at all.
-
-    This does not replace the authentication and security of SSH, it merely
-    puts another layer of protection around it. E.g., suppose an exploit for
-    SSH was discovered, you would most likely have more time to fix/patch
-    the problem than if any client could directly connect to your SSH server.
-
-    For more information http://www.portknocking.org/ and
-    http://www.linuxjournal.com/article/6811
-
-
- Tip:
-
-    If you just want to use the Port Knocking for an SSH shell and not
-    for a VNC tunnel, then specify something like "user@hostname cmd=SHELL"
-    (or "user@hostname cmd=PUTTY" on Windows) in the VNC Host:Display entry box
-    on the main panel.  This will do everything short of starting the viewer.
-    A shortcut for this is Ctrl-S as long as user@hostname is present.
-    
-
- Specifying the Knocks:
-
-    In the text area below "Supply port knocking pattern" you put in the pattern
-    of "knocks" needed for this connection.  You can separate the knocks by
-    commas or put them one per line.
-
-    Each "knock" is of this form:
-
-           [host:]port[/udp] [delay]
-
-    In the simplest form just a numerical port, e.g. 5433, is supplied.
-    Items inside [...] are optional and described below.
-
-    The packet is sent to the same host that the VNC (or SSH) connection will
-    be made to.  If you want it to go to a different host or IP use the [host:]
-    prefix.  It can be either a hostname or numerical IP.
-
-    A TCP packet is sent by default.
-
-    If you need to send a UDP packet, the netcat (aka "nc") program must be
-    installed on Unix (tcl/tk does not support udp connections).  Indicate this
-    with "/udp" following the port number (you can also use "/tcp", but since
-    it is the default it is not necessary).  (You can also use ":udp" to match
-    the knockd syntax).  See the example below.  For convenience a Windows netcat
-    binary is supplied.
-
-    The last field, [delay], is an optional number of milliseconds to delay
-    before continuing on to the next knock.
-
-
- Examples:
-
-           5433, 12321, 1661
-
-           fw.example.com:5433, 12321/udp 3000, 1661 2000
-
-           fw.example.com:5433
-           12321/udp 3000
-           1661 2000
-
-    Note how the first two examples separate their knocks via commas ",".
-    The 3rd example is equivalent to the 2nd and splits them up by new lines.
-
-    Note for each knock any second number (e.g. the "2000" in "1661 2000") is
-    a DELAY in milliseconds, not a port number.  If you had a comma separating
-    them: "1661, 2000" that would mean two separate knocks: one to port 1661
-    followed by one to 2000 (with basically no delay between them).
-
-    In examples 2 and 3, "fw.example.com" represents some machine other than
-    the VNC/SSH host.  By default, the VNC/SSH host is the one the packet is
-    sent to.
-
-    If one of the items is the string "FINISH", then the part before it is
-    used prior to connecting and the part after is used once the connection
-    is finished.  This can be used, say, to close the firewall port.  Example:
-
-           5433, 12321, FINISH, 7659, 2314
-
-    (or one can split them up via lines as above.)
-
-
- Advanced port knock actions:
-
-    If the string in the text field contains anywhere the strings "CMD=", "CMDX=",
-    or "SEND=", then splitting on commas is not done: it is only split on lines.
-
-    Then, if a line begins CMD=... the string after the = is run as an
-    external command.  The command could be anything you want, e.g. it could
-    be a port-knocking client that does the knocking, perhaps encrypting the
-    "knocks" pattern somehow or using a Single Packet Authorization method such
-    as http://www.cipherdyne.com/fwknop/
-
-    Extra quotes (sometimes "'foo bar'") may be needed to preserve spaces in
-    command line arguments because the tcl/tk eval(n) command is used.  You
-    can also use {...} for quoting strings with spaces.
-
-    If a line begins CMDX=... then before the command is run the following
-    tokens are expanded to strings:
-
-      %IP       Current machine's IP address (NAT may make this not useful).
-      %NAT      Try to get effective IP by contacting http://www.whatismyip.com
-      %HOST     The remote host of the connection.
-      %USER     The current user.
-      %SECS     The current time in seconds (platform dependent).
-      %MSECS    Platform dependent time having at least millisecond granularity.
-
-   Lines not matching CMD= or CMDX= are treated as normal port knocks but with
-   one exception.  If a line ends in SEND=... (i.e. after the [host:]port,
-   etc., part) then the string after the = is sent as a payload for the tcp
-   or udp connection to [host:]port.  netcat is used for these SEND cases
-   (and must be available on Unix).  If newlines (\n) are needed in the
-   SEND string, use %NEWLINE.  Sending binary data is not yet supported;
-   use CMD= with your own program.
-
-
- Advanced Examples:
-
-      CMD=port_knock_client -password wombat33
-      CMDX=port_knock_client -password wombat33 -host %HOST -src %NAT
-
-      fw.example.com:5433/udp SEND=ASDLFKSJDF
-
-
- More tricks:
-
-      To temporarily "comment out" a knock, insert a leading "#" character.
-
-      Use "sleep N" to insert a raw sleep for N milliseconds (e.g. between
-      CMD=... items or at the very end of the knocks to wait).
-
-      If a knock entry matches "delay N" the default delay is set to
-      N milliseconds (it is 150 initially).
-
-
- One Time Pads:
-
-      If the text contains a (presumably single) line of the form:
-
-           PAD=/path/to/a/one/time/pad/file
-
-      then that file is opened and the first non-blank line not beginning
-      with "#" is used as the knock pattern.  The pad file is rewritten
-      with that line starting with a "#" (so it will be skipped next time).
-
-      The PAD=... string is replaced with the read-in knock pattern line.
-      So, if needed, one can preface the PAD=... with "delay N" to set the
-      default delay, and one can also put a "sleep N" after the PAD=...
-      line to indicate a final sleep.  One can also surround the PAD=
-      line with other knock and CMD= CMDX= lines, but that usage sounds
-      a bit rare.  Example:
-
-           delay 1000
-           PAD=C:\My Pads\work-pad1.txt
-           sleep 4000
-
-
- Port knock only:
-
-      If, in the 'VNC Host:Display' entry, you use "user@hostname cmd=KNOCK"
-      then only the port-knocking is performed.  A shortcut for this is
-      Ctrl-P as long as hostname is present in the entry box.  If it
-      matches cmd=KNOCKF, i.e. an extra "F", then the port-knocking
-      "FINISH" sequence is sent, if any.  A shortcut for this Shift-Ctrl-P
-      as long as hostname is present.

-.SH DESCRIPTION
-.B ssvnc
-is a tcl/tk gui wrapper that runs on Unix, MacOSX, and Windows.
-It sets up an SSL or SSH tunnel to the remote VNC Server and then launches
-the VNC viewer (either the one provided or another one that you have
-specified) to use that encrypted tunnel to connect to the VNC Server.
-The use of Proxies and Gateways to make the connections is implemented. 
-
-Once you have started the SSVNC gui, you can click on the buttons
-"Help", "Options -> Help", "Certs -> Help", etc. for much information
-on how to use and configure the tool.
-
-In short, you supply a VNC server "hostname:display" in the
-"VNC Host:Display" entry box and then press the "Connect" button to
-connect to the server via SSL (stunnel).  E.g. "far-away.east:0".
-Port numbers are also allowed, e.g. far-away.east:5905.
-
-Or supply user@hostname:display and click on the "Use SSH" option, then
-press the "Connect" button to connect to the server via an SSH tunnel.
-E.g. "fred@far-away.east:0".
-
-Note it is also possible to disable the use of SSL/SSH 
-encryption tunnels by using a vnc:// or Vnc:// prefix before
-host:display.  Shift+Ctrl-E is a short-cut to add/remove it.
-See also the \fB-noenc\fR option below for the 'No Encryption' button.
-
-Normally you do not specify any command line options.  You simply
-run \fBssvnc\fR and use the GUI that starts up.
-
-However, as shortcuts you can supply a VNC host:display (or host:port)
-on the command line to connect to immediately (the GUI is started
-and the connection is initiated).  For example, "\fBssvnc far-away.east:0\fR"
-Instead of a  host:display, you can specify the name of a saved profile to
-automatically load that profile and then connect to its server.  
-For example "\fBssvnc far\fR", if you named the profile "far".
-You can use the \fB-profiles\fR option to list the profiles you have saved.
-
-The related commands \fBsshvnc\fR and \fBtsvnc\fR start up the GUI in
-simplified modes: SSH Only Mode, and Terminal Services Mode, respectively.
-See below and the application Help for more information on the modes.
-
-You can also place certain settings in your ~/.ssvncrc, see the
-SSVNC Help panel ('Tips') for more info.
-
-The \fB-cmd\fR option does not start the GUI, it runs the command
-line utility \fBssvnc_cmd\fR directly with the given arguments.
-\fBssvnc_cmd\fR can launch the viewer directly (\fB-viewer ...\fR)
-or, by default, the \fBss_vncviewer\fR SSL/SSH tunnel wrapper script.
-See its help output for more information.
-
-There are also some command line options described as follows.
-.SH OPTIONS
-.TP
-\fB\-help\fR, \fB\-h\fR
-Prints out to the terminal a brief description and the options.
-.TP
-\fB\--help\fR
-Starts up the GUI as though the 'Help' button was pressed to show the
-main Help panel.
-.TP
-\fB\-cmd\fR \fI[ssvnc_cmd-args]\fR
-Launch the ssvnc_cmd utility command directly (no GUI) with the given
-arguments (for use when ssvnc_cmd is not in one's PATH.) If neither
-ssvnc_cmd nor ssvncviewer is in PATH, one can launch the viewer
-directly via: ssvnc -cmd -viewer [viewer-args]
-.TP
-\fB\-profiles\fR
-List the saved SSVNC profiles you have created.  A profile
-is a destination host with specific parameter settings.
-.TP
-\fB\-list\fR
-Same as \fB\-profiles\fR
-.TP
-\fB\-ssh\fR
-Start in "SSH Only Mode".  No SSL aspects are shown.
-Same as running the command \fBsshvnc\fR
-.TP
-\fB\-ts\fR
-Start in "Terminal Services Mode".  This is like "SSH Only Mode", but
-simpler and assumes \fBx11vnc\fR is available on the remote side
-to start and manage X and VNC sessions.
-Same as running the command \fBtsvnc\fR
-.TP
-\fB\-tso\fR
-Same as \fB-ts\fR "Terminal Services Mode", however never let the
-user leave this mode (no button to switch modes is provided.)
-Same as SSVNC_TS_ALWAYS=1.
-.TP
-\fB\-ssl\fR
-Force the full GUI Mode: both SSL and SSH.  This is the default.
-Same as \fB-ss\fR.
-.TP
-\fB\-nv\fR
-Toggle the "Verify All Certs" button to be off at startup.
-.TP
-\fB\-nvb\fR
-Never show the "Verify All Certs" button.
-Same as SSVNC_NO_VERIFY_ALL_BUTTON=1.
-.TP
-\fB\-bigger\fR
-Make the Profile Selection Dialog window bigger.
-Same as SSVNC_BIGGER_DIALOG=1.
-.TP
-\fB\-noenc\fR
-Start off in a mode where a 'No Encryption' check button is present.
-You can toggle the mode with Ctrl-E.
-Same as SSVNC_DISABLE_ENCRYPTION_BUTTON=1. Or \fInoenc=1\fR in ~/.ssvncrc.
-Selecting no encryption is the same as the vnc:// and Vnc:// prefixes
-described below.  The \fB\-noenc\fR mode is now the default, use \fB-enc\fR
-or \fInoenc=0\fR for the opposite behavior.
-.TP
-\fB\-killstunnel\fR
-On Windows, automatically terminate the STUNNEL process when the viewer
-exits instead of prompting you (same as \fIkillstunnel=1\fR in ssvnc_rc or
-toggle in Options menu)
-.TP
-\fB\-nokillstunnel\fR
-On Windows, disable \fB-killstunnel\fR mode.
-Same as \fIkillstunnel=0\fR in ssvnc_rc or
-toggle in Options menu.  Note that \fB-killstunnel\fR mode is now the default.
-.TP
-\fB\-mycert\fR \fI/path/to/mycert.pem\fR
-Set the default "MyCert" to be \fI/path/to/mycert.pem\fR.
-Same as \fB-cert\fR.
-If the file does not exist, ~/.vnc/certs is prefixed and tried.
-You can also set \fImycert=/path/to/mycert.pem\fR in ~/.ssvncrc.
-.TP
-\fB\-cacert\fR \fI/path/to/cacert.crt\fR
-Set the default "ServerCert" to be \fI/path/to/cacert.crt\fR.
-Same as \fB-ca\fR.
-If the file does not exist, ~/.vnc/certs is prefixed and tried.
-You can also set \fIcacert=/path/to/cacert.crt\fR in ~/.ssvncrc.
-.TP
-\fB\-crl\fR \fI/path/to/mycrl.pem\fR
-Set the default Certificate Revocation List to be \fI/path/to/mycrl.pem\fR.
-If the file does not exist, ~/.vnc/certs is prefixed and tried.
-You can also set \fIcrl=/path/to/mycrl.pem\fR in ~/.ssvncrc.
-.SH URL NOTATION
-Here are all of our URL-like prefixes that you can put in front of
-host:display (or host:port): 
-
-For SSL:  vncs:// vncssl:// and vnc+ssl://
-
-For SSH:  vncssh:// and vnc+ssh://
-
-For No Encryption:  vnc:// and Vnc://
-
-Examples:
-
-To quickly make an SSL connection: \fBssvnc vncs://snoopy.com:0\fR
-
-To quickly make an SSH connection: \fBssvnc vnc+ssh://fred@snoopy.com:0\fR
-
-To quickly make a direct connection: \fBssvnc Vnc://snoopy.com:0\fR
-
-The above will also work in the "VNC Host:Display" entry box in the GUI.
-Press the "Connect" button after entering them.
-
-The difference between vnc:// and Vnc:// is that the latter one will not
-prompt you whether you really want to make an unencrypted connection
-or not.
-.SH FILES
-Your SSVNC vnc profiles are stored in the \fB$HOME/.vnc/profiles\fR
-directory.  They end in suffix \fB.vnc\fR
-
-Your SSVNC vnc certificates and keys are stored in the \fB$HOME/.vnc/certs\fR
-directory.  They typically end in \fB.pem\fR (both certificate and
-private key) or \fB.crt\fR (certificate only).
-
-You can put a few global parameters (e.g. mode=sshvnc) in your
-\fB$HOME/.ssvncrc\fR file (\fBssvnc_rc\fR on Windows); see the
-application Help for more information.
-
-.SH FONTS
-
-The following is from Tip 18 in the Help panel.
-
-Fonts: To change the tk fonts, set these environment variables
-before starting up ssvnc: SSVNC_FONT_DEFAULT and SSVNC_FONT_FIXED.
-For example:
-
-% env SSVNC_FONT_DEFAULT='helvetica -20 bold' ssvnc
-
-% env SSVNC_FONT_FIXED='courier -14' ssvnc
-
-or set both of them at once.
-
-To achieve the same effect, you can also
-set parameters in your ~/.ssvncrc file, for example:
-
-font_default=helvetica -20 bold
-
-font_fixed=courier -14

-.SH DESCRIPTION
-.B ssvncviewer
-is an Xt\-based client application for the VNC (Virtual Network
-Computing) system. It can connect to any VNC\-compatible server such
-as \fBXvnc\fR, WinVNC, or \fBx11vnc\fR, allowing you to control desktop environment
-of a different machine.
-
-ssvncviewer is an enhanced version of the tightvnc unix viewer that can
-take advantage of features in the \fBx11vnc\fR and UltraVNC VNC servers.
-See below for the description of these features.
-
-You can use F8 to display a pop\-up utility menu. Press F8 twice to
-pass single F8 to the remote side.
-.SH OPTIONS
-.TP
-\fB\-help\fR
-Prints a short usage notice to stderr.
-.TP
-\fB\-listen\fR
-Make the viewer listen on port 5500+\fIdisplay\fR for reverse
-connections from a server. WinVNC supports reverse connections using
-the "Add New Client" menu option, or the \-connect command line
-option. \fBXvnc\fR requires the use of the helper program
-\fBvncconnect\fR.
-.TP
-\fB\-via\fR \fIgateway\fR
-Automatically create encrypted TCP tunnel to the \fIgateway\fR machine
-before connection, connect to the \fIhost\fR through that tunnel
-(TightVNC\-specific). By default, this option invokes SSH local port
-forwarding, assuming that SSH client binary can be accessed as
-/usr/bin/ssh. Note that when using the \fB\-via\fR option, the host
-machine name should be specified as known to the gateway machine, e.g. 
-"localhost" denotes the \fIgateway\fR, not the machine where vncviewer
-was launched. See the ENVIRONMENT section below for the information on
-configuring the \fB\-via\fR option.
-.TP
-\fB\-shared\fR
-When connecting, specify that a shared connection is requested. In
-TightVNC, this is the default mode, allowing you to share the desktop
-with other clients already using it.
-.TP
-\fB\-noshared\fR
-When connecting, specify that the session may not be shared. This
-would either disconnect other connected clients or refuse your
-connection, depending on the server configuration.
-.TP
-\fB\-viewonly\fR
-Disable transfer of mouse and keyboard events from the client to the
-server.
-.TP
-\fB\-fullscreen\fR
-Start in full\-screen mode. Please be aware that operating in
-full\-screen mode may confuse X window managers. Typically, such
-conflicts cause incorrect handling of input focus or make the viewer
-window disappear mysteriously. See the grabKeyboard setting in the
-RESOURCES section below for a method to solve input focus problem.
-.TP
-\fB\-noraiseonbeep\fR
-By default, the viewer shows and raises its window on remote beep
-(bell) event. This option disables such behaviour
-(TightVNC\-specific).
-.TP
-\fB\-user\fR \fIusername\fR
-User name for Unix login authentication. Default is to use current
-Unix user name. If this option was given, the viewer will prefer Unix
-login authentication over the standard VNC authentication.
-.TP
-\fB\-passwd\fR \fIpasswd\-file\fR
-File from which to get the password (as generated by the
-\fBvncpasswd\fR(1) program). This option affects only the standard VNC
-authentication.
-.TP
-\fB\-encodings\fR \fIencoding\-list\fR
-TightVNC supports several different compression methods to encode
-screen updates; this option specifies a set of them to use in order of
-preference. Encodings are specified separated with spaces, and must
-thus be enclosed in quotes if more than one is specified.  Commas may be used to avoid spaces.
-Available encodings, in default order for a remote connection, are
-"copyrect tight hextile zlib corre rre raw". For a local connection
-(to the same machine), the default order to try is "raw copyrect tight
-hextile zlib corre rre". Raw encoding is always assumed as a last option
-if no other encoding can be used for some reason. For more information
-on encodings, see the section ENCODINGS below.
-.TP
-\fB\-bgr233\fR
-Always use the BGR233 format to encode pixel data. This reduces
-network traffic, but colors may be represented inaccurately. The
-bgr233 format is an 8\-bit "true color" format, with 2 bits blue, 3
-bits green, and 3 bits red.
-.TP
-\fB\-owncmap\fR
-Try to use a PseudoColor visual and a private colormap. This allows
-the VNC server to control the colormap.
-.TP
-\fB\-truecolour\fR, \fB\-truecolor\fR
-Try to use a TrueColor visual.
-.TP
-\fB\-depth\fR \fIdepth\fR
-On an X server which supports multiple TrueColor visuals of different
-depths, attempt to use the specified one (in bits per pixel); if
-successful, this depth will be requested from the VNC server.
-.TP
-\fB\-compresslevel \fIlevel\fR
-Use specified compression \fIlevel\fR (0..9) for "tight" and "zlib"
-encodings (TightVNC\-specific). Level 1 uses minimum of CPU time and
-achieves weak compression ratios, while level 9 offers best
-compression but is slow in terms of CPU time consumption on the server
-side. Use high levels with very slow network connections, and low
-levels when working over high\-speed LANs. It's not recommended to use
-compression level 0, reasonable choices start from the level 1.
-.TP
-\fB\-quality \fIlevel\fR
-Use the specified JPEG quality \fIlevel\fR (0..9) for the "tight"
-encoding (TightVNC\-specific). Quality level 0 denotes bad image
-quality but very impressive compression ratios, while level 9 offers
-very good image quality at lower compression ratios. Note that the
-"tight" encoder uses JPEG to encode only those screen areas that look
-suitable for lossy compression, so quality level 0 does not always
-mean unacceptable image quality.
-.TP
-\fB\-nojpeg\fR
-Disable lossy JPEG compression in Tight encoding (TightVNC\-specific). 
-Disabling JPEG compression is not a good idea in typical cases, as
-that makes the Tight encoder less efficient. You might want to use
-this option if it's absolutely necessary to achieve perfect image
-quality (see also the \fB\-quality\fR option).
-.TP
-\fB\-nocursorshape\fR
-Disable cursor shape updates, protocol extensions used to handle
-remote cursor movements locally on the client side
-(TightVNC\-specific). Using cursor shape updates decreases delays with
-remote cursor movements, and can improve bandwidth usage dramatically. 
-.TP
-\fB\-x11cursor\fR
-Use a real X11 cursor with X-style cursor shape updates, instead of
-drawing the remote cursor on the framebuffer. This option also
-disables the dot cursor, and disables cursor position updates in
-non-fullscreen mode.
-.TP
-\fB\-autopass\fR
-Read a plain-text password from stdin. This option affects only the
-standard VNC authentication.
-
-.SH Enhanced TightVNC Viewer (SSVNC) OPTIONS
-.TP
-Enhanced TightVNC Viewer (SSVNC) web page is located at:
-.TP
-http://www.karlrunge.com/x11vnc/ssvnc.html
-.TP
-Note: ZRLE and ZYWRLE encodings are now supported.
-.TP
-Note: F9 is shortcut to Toggle FullScreen mode.
-.TP
-Note: In -listen mode set the env var. SSVNC_MULTIPLE_LISTEN=1
-to allow more than one incoming VNC server at a time.
-This is the same as -multilisten described below.  Set
-SSVNC_MULTIPLE_LISTEN=MAX:n to allow no more than "n"
-simultaneous reverse connections.
-
-If the host:port is specified as "exec=command args..."
-then instead of making a TCP/IP socket connection to the
-remote VNC server, "command args..." is executed and the
-viewer is attached to its stdio.  This enables tunnelling
-established via an external command, e.g. an stunnel(8)
-that does not involve a listening socket.
-This mode does not work for -listen reverse connections.
-
-If the host:port is specified as "fd=n" then it is assumed
-n is an already opened file descriptor to the socket. (i.e
-the parent did fork+exec)
-
-If the host:port contains a '/' it is interpreted as a
-unix-domain socket (AF_LOCAL insead of AF_INET)
-.TP
-\fB\-multilisten\fR
-As in -listen (reverse connection listening) except
-allow more than one incoming VNC server to be connected
-at a time.  The default for -listen of only one at a
-time tries to play it safe by not allowing anyone on
-the network to put (many) desktops on your screen over
-a long window of time. Use -multilisten for no limit.
-.TP
-\fB\-acceptpopup\fR
-In \fB\-listen\fR (reverse connection listening) mode when
-a reverse VNC connection comes in show a popup asking
-whether to Accept or Reject the connection.  The IP
-address of the connecting host is shown.  Same as
-setting the env. var. SSVNC_ACCEPT_POPUP=1.
-.TP
-\fB\-acceptpopupsc\fR
-As in \fB\-acceptpopup\fR except assume UltraVNC Single
-Click (SC) server.  Retrieve User and ComputerName
-info from UltraVNC Server and display in the Popup.
-.TP
-\fB\-use64\fR
-In \fB\-bgr233\fR mode, use 64 colors instead of 256.
-.TP
-\fB\-bgr222\fR
-Same as \fB\-use64\fR.
-.TP
-\fB\-use8\fR
-In \fB\-bgr233\fR mode, use 8 colors instead of 256.
-.TP
-\fB\-bgr111\fR
-Same as \fB\-use8\fR.
-.TP
-\fB\-16bpp\fR
-If the vnc viewer X display is depth 24 at 32bpp
-request a 16bpp format from the VNC server to cut
-network traffic by up to 2X, then tranlate the
-pixels to 32bpp locally.
-.TP
-\fB\-bgr565\fR
-Same as \fB\-16bpp\fR.
-.TP
-\fB\-grey\fR
-Use a grey scale for the 16- and 8\fB\-bpp\fR modes.
-.TP
-\fB\-alpha\fR
-Use alphablending transparency for local cursors
-requires: x11vnc server, both client and server
-must be 32bpp and same endianness.
-.TP
-\fB\-scale\fR \fIstr\fR
-Scale the desktop locally.  The string "str" can
-a floating point ratio, e.g. "0.9", or a fraction,
-e.g. "3/4", or WxH, e.g. 1280x1024.  Use "fit"
-to fit in the current screen size.  Use "auto" to
-fit in the window size.  "str" can also be set by
-the env. var. SSVNC_SCALE.
-
-If you observe mouse trail painting errors, enable
-X11 Cursor mode (either via Popup or \fB\-x11cursor\fR.)
-
-Note that scaling is done in software and so can be
-slow and requires more memory.  Some speedup Tips:
-
-ZRLE is faster than Tight in this mode.  When
-scaling is first detected, the encoding will
-be automatically switched to ZRLE.  Use the
-Popup menu if you want to go back to Tight.
-Set SSVNC_PRESERVE_ENCODING=1 to disable this.
-
-Use a solid background on the remote side.
-(e.g. manually or via x11vnc \fB\-solid\fR ...)
-
-If the remote server is x11vnc, try client
-side caching: x11vnc \fB\-ncache\fR 10 ...
-.TP
-\fB\-ycrop\fR n
-Only show the top n rows of the framebuffer.  For
-use with x11vnc \fB\-ncache\fR client caching option
-to help "hide" the pixel cache region.
-Use a negative value (e.g. \fB\-1\fR) for autodetection.
-Autodetection will always take place if the remote
-fb height is more than 2 times the width.
-.TP
-\fB\-sbwidth\fR n
-Scrollbar width for x11vnc \fB\-ncache\fR mode (\fB\-ycrop\fR),
-default is very narrow: 2 pixels, it is narrow to
-avoid distraction in \fB\-ycrop\fR mode.
-.TP
-\fB\-nobell\fR
-Disable bell.
-.TP
-\fB\-rawlocal\fR
-Prefer raw encoding for localhost, default is
-no, i.e. assumes you have a SSH tunnel instead.
-.TP
-\fB\-notty\fR
-Try to avoid using the terminal for interactive
-responses: use windows for messages and prompting
-instead.  Messages will also be printed to terminal.
-.TP
-\fB\-sendclipboard\fR
-Send the X CLIPBOARD selection (i.e. Ctrl+C,
-Ctrl+V) instead of the X PRIMARY selection (mouse
-select and middle button paste.)
-.TP
-\fB\-sendalways\fR
-Whenever the mouse enters the VNC viewer main
-window, send the selection to the VNC server even if
-it has not changed.  This is like the Xt resource
-translation SelectionToVNC(always)
-.TP
-\fB\-recvtext\fR
-str   When cut text is received from the VNC server,
-ssvncviewer will set both the X PRIMARY and the
-X CLIPBOARD local selections.  To control which
-is set, specify 'str' as 'primary', 'clipboard',
-or 'both' (the default.)
-.TP
-\fB\-graball\fR
-Grab the entire X server when in fullscreen mode,
-needed by some old window managers like fvwm2.
-.TP
-\fB\-popupfix\fR
-Warp the popup back to the pointer position,
-needed by some old window managers like fvwm2.
-.TP
-\fB\-grabkbd\fR
-Grab the X keyboard when in fullscreen mode,
-needed by some window managers. Same as \fB\-grabkeyboard\fR.
-\fB\-grabkbd\fR is the default, use \fB\-nograbkbd\fR to disable.
-.TP
-\fB\-bs\fR, \fB\-nobs\fR
-Whether or not to use X server Backingstore for the
-main viewer window.  The default is to not, mainly
-because most Linux, etc, systems X servers disable
-*all* Backingstore by default.  To re\fB\-enable\fR it put
-
-Option "Backingstore"
-
-in the Device section of /etc/X11/xorg.conf.
-In \fB\-bs\fR mode with no X server backingstore, whenever an
-area of the screen is re\fB\-exposed\fR it must go out to the
-VNC server to retrieve the pixels. This is too slow.
-
-In \fB\-nobs\fR mode, memory is allocated by the viewer to
-provide its own backing of the main viewer window. This
-actually makes some activities faster (changes in large
-regions) but can appear to "flash" too much.
-.TP
-\fB\-noshm\fR
-Disable use of MIT shared memory extension (not recommended)
-.TP
-\fB\-termchat\fR
-Do the UltraVNC chat in the terminal vncviewer is in
-instead of in an independent window.
-.TP
-\fB\-unixpw\fR \fIstr\fR
-Useful for logging into x11vnc in \fB\-unixpw\fR mode. "str" is a
-string that allows many ways to enter the Unix Username
-and Unix Password.  These characters: username, newline,
-password, newline are sent to the VNC server after any VNC
-authentication has taken place.  Under x11vnc they are
-used for the \fB\-unixpw\fR login.  Other VNC servers could do
-something similar.
-
-You can also indicate "str" via the environment
-variable SSVNC_UNIXPW.
-
-Note that the Escape key is actually sent first to tell
-x11vnc to not echo the Unix Username back to the VNC
-viewer. Set SSVNC_UNIXPW_NOESC=1 to override this.
-
-If str is ".", then you are prompted at the command line
-for the username and password in the normal way.  If str is
-"-" the stdin is read via getpass(3) for username@password.
-Otherwise if str is a file, it is opened and the first line
-read is taken as the Unix username and the 2nd as the
-password. If str prefixed by "rm:" the file is removed
-after reading. Otherwise, if str has a "@" character,
-it is taken as username@password. Otherwise, the program
-exits with an error. Got all that?
-.TP
-\fB-repeater\fR \fIstr\fR
-This is for use with UltraVNC repeater proxy described
-here: http://www.uvnc.com/addons/repeater.html.  The "str"
-is the ID string to be sent to the repeater.  E.g. ID:1234
-It can also be the hostname and port or display of the VNC
-server, e.g. 12.34.56.78:0 or snoopy.com:1.  Note that when
-using -repeater, the host:dpy on the cmdline is the repeater
-server, NOT the VNC server.  The repeater will connect you.
-
-Example: vncviewer ... -repeater ID:3333 repeat.host:5900
-
-Example: vncviewer ... -repeater vhost:0 repeat.host:5900
-
-Use, e.g., '-repeater SCIII=ID:3210' if the repeater is a
-Single Click III (SSL) repeater (repeater_SSL.exe) and you
-are passing the SSL part of the connection through stunnel, socat, etc.
-This way the magic UltraVNC string 'testB' needed to work with the
-repeater is sent to it.
-.TP
-\fB-rfbversion\fR \fIstr\fR
-Set the advertised RFB version.  E.g.: -rfbversion 3.6  For some
-servers, e.g. UltraVNC this needs to be done.
-.TP
-\fB-ultradsm\fR
-UltraVNC has symmetric private encryption DSM plugins.  See
-http://www.uvnc.com/features/encryption.html.  It is assumed
-you are using a unix program (e.g. our ultravnc_dsm_helper) to
-encrypt and decrypt the UltraVNC DSM stream. IN ADDITION TO
-THAT supply -ultradsm to tell THIS viewer to modify the RFB
-data sent so as to work with the UltraVNC Server.  For some
-reason, each RFB msg type must be sent twice under DSM.
-.TP
-\fB\-mslogon\fR \fIuser\fR
-Use Windows MS Logon to an UltraVNC server.  Supply the
-username or "1" to be prompted.  The default is to
-autodetect the UltraVNC MS Logon server and prompt for
-the username and password.
-
-IMPORTANT NOTE: The UltraVNC MS-Logon Diffie-Hellman
-exchange is very weak and can be brute forced to recover
-your username and password in a few seconds of CPU
-time.  To be safe, be sure to use an additional encrypted
-tunnel (e.g. SSL or SSH) for the entire VNC session.
-.TP
-\fB\-chatonly\fR
-Try to be a client that only does UltraVNC text chat. This
-mode is used by x11vnc to present a chat window on the physical
-X11 console (i.e. to chat with the person at the display).
-.TP
-\fB-env\fR \fIVAR=VALUE\fR
-To save writing a shell script to set environment
-variables, specify as many as you need on the command line.  For example,
--env SSVNC_MULTIPLE_LISTEN=MAX:5 -env EDITOR=vi
-.TP
-\fB\-noipv6\fR
-Disable all IPv6 sockets.  Same as VNCVIEWER_NO_IPV6=1.
-.TP
-\fB\-noipv4\fR
-Disable all IPv4 sockets.  Same as VNCVIEWER_NO_IPV4=1.
-.TP
-\fB\-printres\fR
-Print out the Ssvnc X resources (appdefaults) and
-then exit. You can save them to a file and customize them (e.g. the
-keybindings and Popup menu)  Then point to the file via
-XENVIRONMENT or XAPPLRESDIR.
-.TP
-\fB\-pipeline\fR
-Like TurboVNC, request the next framebuffer update as soon
-as possible instead of waiting until the end of the current
-framebuffer update coming in.  Helps 'pipeline' the updates.
-This is currently the default, use \fB-nopipeline\fR to disable.
-.TP
-\fB\-appshare\fR
-Enable features for use with x11vnc's \fB\-appshare\fR mode where
-instead of sharing the full desktop only the application's
-windows are shared.  Viewer multilisten mode is used to
-create the multiple windows: \fB\-multilisten\fR is implied.
-See 'x11vnc \fB\-appshare\fR \fB\-help\fR' more information on the mode.
-Features enabled in the viewer under \fB\-appshare\fR are:
-Minimum extra text in the title, auto \fB\-ycrop\fR is disabled,
-x11vnc \fB\-remote_prefix\fR X11VNC_APPSHARE_CMD: message channel,
-x11vnc initial window position hints.  See also Escape Keys
-below for additional key and mouse bindings.
-.TP
-\fB\-escape \fR\fIstr\fR
-This sets the 'Escape Keys' modifier sequence and enables
-escape keys mode.  When the modifier keys escape sequence
-is held down, the next keystroke is interpreted locally
-to perform a special action instead of being sent to the
-remote VNC server.
-
-Use '\fB\-escape\fR default' for the default modifier sequence.
-(Unix: Alt_L,Super_L and MacOSX: Control_L,Meta_L)
-
-Here are the 'Escape Keys: Help+Set' instructions from the Popup:
-
-Escape Keys:  Enter a comma separated list of modifier keys to be the 'escape
-sequence'.  When these keys are held down, the next keystroke is
-interpreted locally to invoke a special action instead of being sent to
-the remote VNC server.  In other words, a set of 'Hot Keys'.
-
-Here is the list of local key mappings to special actions:
-
-r: refresh desktop  b: toggle bell  c: toggle full-color
-
-f: file transfer    x: x11cursor    z: toggle Tight/ZRLE
-
-l: full screen      g: graball      e: escape keys dialog
-
-s: scale dialog     +: scale up (=) -: scale down (_)
-
-t: text chat                        a: alphablend cursor
-
-V: toggle viewonly  Q: quit viewer  123456: UltraVNC scale 1/n
-
-Arrow keys: pan the viewport about 10% for each keypress.
-
-PageUp/PageDown: pan the viewport by a screenful vertically.
-
-Home/End: pan the viewport by a screenful horizontally.
-
-KeyPad Arrows: pan the viewport by 1 pixel for each keypress.
-
-Dragging the Mouse with Button1 pressed also pans the viewport.
-
-Clicking Mouse Button3 brings up the Popup Menu.
-
-The above mappings are \fBalways\fR active in ViewOnly mode, unless you set
-the Escape Keys value to 'never'.
-
-x11vnc -appshare hot-keys:  x11vnc has a simple application sharing mode
-that enables the viewer-side to move, resize, or raise the remote toplevel
-windows.  To enable it, hold down Shift + the Escape Keys and press these:
-
-Arrow keys: move the remote window around in its desktop.
-
-PageUp/PageDn/Home/End:  resize the remote window.
-
-+/-: raise or lower the remote window.
-
-M or Button1 move win to local position;  D or Button3: delete remote win.
-
-If the Escape Keys value below is set to 'default' then a default list of
-of modifier keys is used.  For Unix it is: Alt_L,Super_L and for MacOSX it
-is Control_L,Meta_L.  Note: the Super_L key usually has a Windows(TM) Flag
-on it.  Also note the _L and _R mean the key is on the LEFT or RIGHT side
-of the keyboard.
-
-On Unix   the default is Alt and Windows keys on Left side of keyboard.
-On MacOSX the default is Control and Command keys on Left side of keyboard.
-
-Example: Press and hold the Alt and Windows keys on the LEFT side of the
-keyboard and then press 'c' to toggle the full-color state.  Or press 't'
-to toggle the ultravnc Text Chat window, etc.
-
-To use something besides the default, supply a comma separated list (or a
-single one) from: Shift_L Shift_R Control_L Control_R Alt_L Alt_R Meta_L
-Meta_R Super_L Super_R Hyper_L Hyper_R or Mode_switch.

-       them.  x11vnc/libvncserver supports some of them.
-
- Send Clipboard not Primary  ~ -sendclipboard
- Send Selection Every time   ~ -sendalways
-
-.SH ENCODINGS
-The server supplies information in whatever format is desired by the
-client, in order to make the client as easy as possible to implement. 
-If the client represents itself as able to use multiple formats, the
-server will choose one.
-
-.I Pixel format
-refers to the representation of an individual pixel. The most common
-formats are 24 and 16 bit "true\-color" values, and 8\-bit "color map"
-representations, where an arbitrary map converts the color number to
-RGB values.
-
-.I Encoding
-refers to how a rectangle of pixels are sent (all pixel information in
-VNC is sent as rectangles). All rectangles come with a header giving
-the location and size of the rectangle and an encoding type used by
-the data which follows. These types are listed below.
-.TP
-.B Raw
-The raw encoding simply sends width*height pixel values. All clients
-are required to support this encoding type. Raw is also the fastest
-when the server and viewer are on the same machine, as the connection
-speed is essentially infinite and raw encoding minimizes processing
-time.
-.TP
-.B CopyRect
-The Copy Rectangle encoding is efficient when something is being
-moved; the only data sent is the location of a rectangle from which
-data should be copied to the current location. Copyrect could also be
-used to efficiently transmit a repeated pattern.
-.TP
-.B RRE
-The Rise\-and\-Run\-length\-Encoding is basically a 2D version of
-run\-length encoding (RLE). In this encoding, a sequence of identical
-pixels are compressed to a single value and repeat count. In VNC, this
-is implemented with a background color, and then specifications of an
-arbitrary number of subrectangles and color for each. This is an
-efficient encoding for large blocks of constant color.
-.TP
-.B CoRRE
-This is a minor variation on RRE, using a maximum of 255x255 pixel
-rectangles. This allows for single\-byte values to be used, reducing
-packet size. This is in general more efficient, because the savings
-from sending 1\-byte values generally outweighs the losses from the
-(relatively rare) cases where very large regions are painted the same
-color.
-.TP
-.B Hextile
-Here, rectangles are split up in to 16x16 tiles, which are sent in a
-predetermined order. The data within the tiles is sent either raw or
-as a variant on RRE. Hextile encoding is usually the best choice for
-using in high\-speed network environments (e.g. Ethernet local\-area
-networks).
-.TP
-.B Zlib
-Zlib is a very simple encoding that uses zlib library to compress raw
-pixel data. This encoding achieves good compression, but consumes a
-lot of CPU time. Support for this encoding is provided for
-compatibility with VNC servers that might not understand Tight
-encoding which is more efficient than Zlib in nearly all real\-life
-situations.
-.TP
-.B Tight
-Like Zlib encoding, Tight encoding uses zlib library to compress the
-pixel data, but it pre\-processes data to maximize compression ratios,
-and to minimize CPU usage on compression. Also, JPEG compression may
-be used to encode color\-rich screen areas (see the description of
-\-quality and \-nojpeg options above). Tight encoding is usually the
-best choice for low\-bandwidth network environments (e.g. slow modem
-connections).
-.TP
-.B ZRLE
-The SSVNC viewer has ported the RealVNC (www.realvnc.com) ZRLE encoding
-to the unix tightvnc viewer.
-.TP
-.B ZYWRLE
-The SSVNC viewer has ported the Hitachi lossy wavelet based ZRLE
-encoding from http://mobile.hitachi-system.co.jp/publications/ZYWRLE/ 
-to the unix tightvnc viewer.
-.SH RESOURCES
-X resources that \fBvncviewer\fR knows about, aside from the
-normal Xt resources, are as follows:
-.TP
-.B shareDesktop
-Equivalent of \fB\-shared\fR/\fB\-noshared\fR options. Default true.
-.TP
-.B viewOnly
-Equivalent of \fB\-viewonly\fR option. Default false.
-.TP
-.B fullScreen
-Equivalent of \fB\-fullscreen\fR option. Default false.
-.TP
-.B grabKeyboard
-Grab keyboard in full-screen mode. This can help to solve problems
-with losing keyboard focus. Default false.
-.TP
-.B raiseOnBeep
-Equivalent of \fB\-noraiseonbeep\fR option, when set to false. Default
-true.
-.TP
-.B passwordFile
-Equivalent of \fB\-passwd\fR option.
-.TP
-.B userLogin
-Equivalent of \fB\-user\fR option.
-.TP
-.B passwordDialog
-Whether to use a dialog box to get the password (true) or get it from
-the tty (false). Irrelevant if \fBpasswordFile\fR is set. Default
-false.
-.TP
-.B encodings
-Equivalent of \fB\-encodings\fR option.
-.TP
-.B compressLevel
-Equivalent of \fB\-compresslevel\fR option (TightVNC\-specific).
-.TP
-.B qualityLevel
-Equivalent of \fB\-quality\fR option (TightVNC\-specific).
-.TP
-.B enableJPEG
-Equivalent of \fB\-nojpeg\fR option, when set to false. Default true.
-.TP
-.B useRemoteCursor
-Equivalent of \fB\-nocursorshape\fR option, when set to false
-(TightVNC\-specific). Default true.
-.TP
-.B useBGR233
-Equivalent of \fB\-bgr233\fR option. Default false.
-.TP
-.B nColours
-When using BGR233, try to allocate this many "exact" colors from the
-BGR233 color cube. When using a shared colormap, setting this resource
-lower leaves more colors for other X clients. Irrelevant when using
-truecolor. Default is 256 (i.e. all of them).
-.TP
-.B useSharedColours
-If the number of "exact" BGR233 colors successfully allocated is less
-than 256 then the rest are filled in using the "nearest" colors
-available. This resource says whether to only use the "exact" BGR233
-colors for this purpose, or whether to use other clients' "shared"
-colors as well. Default true (i.e. use other clients' colors).
-.TP
-.B forceOwnCmap
-Equivalent of \fB\-owncmap\fR option. Default false.
-.TP
-.B forceTrueColour
-Equivalent of \fB\-truecolour\fR option. Default false.
-.TP
-.B requestedDepth
-Equivalent of \fB\-depth\fR option.
-.TP
-.B useSharedMemory
-Use MIT shared memory extension if on the same machine as the X
-server. Default true.
-.TP
-.B wmDecorationWidth, wmDecorationHeight
-The total width and height taken up by window manager decorations.
-This is used to calculate the maximum size of the VNC viewer window. 
-Default is width 4, height 24.
-.TP
-.B bumpScrollTime, bumpScrollPixels
-When in full screen mode and the VNC desktop is bigger than the X
-display, scrolling happens whenever the mouse hits the edge of the
-screen. The maximum speed of scrolling is bumpScrollPixels pixels
-every bumpScrollTime milliseconds. The actual speed of scrolling will
-be slower than this, of course, depending on how fast your machine is. 
-Default 20 pixels every 25 milliseconds.
-.TP
-.B popupButtonCount
-The number of buttons in the popup window. See the README file for
-more information on how to customize the buttons.
-.TP
-.B debug
-For debugging. Default false.
-.TP
-.B rawDelay, copyRectDelay
-For debugging, see the README file for details. Default 0 (off).
-.SH ENVIRONMENT
-When started with the \fB\-via\fR option, vncviewer reads the
-\fBVNC_VIA_CMD\fR environment variable, expands patterns beginning
-with the "%" character, and executes result as a command assuming that
-it would create TCP tunnel that should be used for VNC connection. If
-not set, this environment variable defaults to "/usr/bin/ssh -f -L
-%L:%H:%R %G sleep 20".
-
-The following patterns are recognized in the \fBVNC_VIA_CMD\fR (note
-that all the patterns %G, %H, %L and %R must be present in the command
-template):
-.TP
-.B %%
-A literal "%";
-.TP
-.B %G
-gateway host name;
-.TP
-.B %H
-remote VNC host name, as known to the gateway;
-.TP
-.B %L
-local TCP port number;
-.TP
-.B %R
-remote TCP port number.

-+.SH DESCRIPTION
-+.B ssvncviewer
-+is an Xt\-based client application for the VNC (Virtual Network
-+Computing) system. It can connect to any VNC\-compatible server such
-+as \fBXvnc\fR, WinVNC, or \fBx11vnc\fR, allowing you to control desktop environment
-+of a different machine.
-+
-+ssvncviewer is an enhanced version of the tightvnc unix viewer that can
-+take advantage of features in the \fBx11vnc\fR and UltraVNC VNC servers.
-+See below for the description of these features.
-+
-+You can use F8 to display a pop\-up utility menu. Press F8 twice to
-+pass single F8 to the remote side.
-+.SH OPTIONS
-+.TP
-+\fB\-help\fR
-+Prints a short usage notice to stderr.
-+.TP
-+\fB\-listen\fR
-+Make the viewer listen on port 5500+\fIdisplay\fR for reverse
-+connections from a server. WinVNC supports reverse connections using
-+the "Add New Client" menu option, or the \-connect command line
-+option. \fBXvnc\fR requires the use of the helper program
-+\fBvncconnect\fR.
-+.TP
-+\fB\-via\fR \fIgateway\fR
-+Automatically create encrypted TCP tunnel to the \fIgateway\fR machine
-+before connection, connect to the \fIhost\fR through that tunnel
-+(TightVNC\-specific). By default, this option invokes SSH local port
-+forwarding, assuming that SSH client binary can be accessed as
-+/usr/bin/ssh. Note that when using the \fB\-via\fR option, the host
-+machine name should be specified as known to the gateway machine, e.g. 
-+"localhost" denotes the \fIgateway\fR, not the machine where vncviewer
-+was launched. See the ENVIRONMENT section below for the information on
-+configuring the \fB\-via\fR option.
-+.TP
-+\fB\-shared\fR
-+When connecting, specify that a shared connection is requested. In
-+TightVNC, this is the default mode, allowing you to share the desktop
-+with other clients already using it.
-+.TP
-+\fB\-noshared\fR
-+When connecting, specify that the session may not be shared. This
-+would either disconnect other connected clients or refuse your
-+connection, depending on the server configuration.
-+.TP
-+\fB\-viewonly\fR
-+Disable transfer of mouse and keyboard events from the client to the
-+server.
-+.TP
-+\fB\-fullscreen\fR
-+Start in full\-screen mode. Please be aware that operating in
-+full\-screen mode may confuse X window managers. Typically, such
-+conflicts cause incorrect handling of input focus or make the viewer
-+window disappear mysteriously. See the grabKeyboard setting in the
-+RESOURCES section below for a method to solve input focus problem.
-+.TP
-+\fB\-noraiseonbeep\fR
-+By default, the viewer shows and raises its window on remote beep
-+(bell) event. This option disables such behaviour
-+(TightVNC\-specific).
-+.TP
-+\fB\-user\fR \fIusername\fR
-+User name for Unix login authentication. Default is to use current
-+Unix user name. If this option was given, the viewer will prefer Unix
-+login authentication over the standard VNC authentication.
-+.TP
-+\fB\-passwd\fR \fIpasswd\-file\fR
-+File from which to get the password (as generated by the
-+\fBvncpasswd\fR(1) program). This option affects only the standard VNC
-+authentication.
-+.TP
-+\fB\-encodings\fR \fIencoding\-list\fR
-+TightVNC supports several different compression methods to encode
-+screen updates; this option specifies a set of them to use in order of
-+preference. Encodings are specified separated with spaces, and must
-+thus be enclosed in quotes if more than one is specified.  Commas may be used to avoid spaces.
-+Available encodings, in default order for a remote connection, are
-+"copyrect tight hextile zlib corre rre raw". For a local connection
-+(to the same machine), the default order to try is "raw copyrect tight
-+hextile zlib corre rre". Raw encoding is always assumed as a last option
-+if no other encoding can be used for some reason. For more information
-+on encodings, see the section ENCODINGS below.
-+.TP
-+\fB\-bgr233\fR
-+Always use the BGR233 format to encode pixel data. This reduces
-+network traffic, but colors may be represented inaccurately. The
-+bgr233 format is an 8\-bit "true color" format, with 2 bits blue, 3
-+bits green, and 3 bits red.
-+.TP
-+\fB\-owncmap\fR
-+Try to use a PseudoColor visual and a private colormap. This allows
-+the VNC server to control the colormap.
-+.TP
-+\fB\-truecolour\fR, \fB\-truecolor\fR
-+Try to use a TrueColor visual.
-+.TP
-+\fB\-depth\fR \fIdepth\fR
-+On an X server which supports multiple TrueColor visuals of different
-+depths, attempt to use the specified one (in bits per pixel); if
-+successful, this depth will be requested from the VNC server.
-+.TP
-+\fB\-compresslevel \fIlevel\fR
-+Use specified compression \fIlevel\fR (0..9) for "tight" and "zlib"
-+encodings (TightVNC\-specific). Level 1 uses minimum of CPU time and
-+achieves weak compression ratios, while level 9 offers best
-+compression but is slow in terms of CPU time consumption on the server
-+side. Use high levels with very slow network connections, and low
-+levels when working over high\-speed LANs. It's not recommended to use
-+compression level 0, reasonable choices start from the level 1.
-+.TP
-+\fB\-quality \fIlevel\fR
-+Use the specified JPEG quality \fIlevel\fR (0..9) for the "tight"
-+encoding (TightVNC\-specific). Quality level 0 denotes bad image
-+quality but very impressive compression ratios, while level 9 offers
-+very good image quality at lower compression ratios. Note that the
-+"tight" encoder uses JPEG to encode only those screen areas that look
-+suitable for lossy compression, so quality level 0 does not always
-+mean unacceptable image quality.
-+.TP
-+\fB\-nojpeg\fR
-+Disable lossy JPEG compression in Tight encoding (TightVNC\-specific). 
-+Disabling JPEG compression is not a good idea in typical cases, as
-+that makes the Tight encoder less efficient. You might want to use
-+this option if it's absolutely necessary to achieve perfect image
-+quality (see also the \fB\-quality\fR option).
-+.TP
-+\fB\-nocursorshape\fR
-+Disable cursor shape updates, protocol extensions used to handle
-+remote cursor movements locally on the client side
-+(TightVNC\-specific). Using cursor shape updates decreases delays with
-+remote cursor movements, and can improve bandwidth usage dramatically. 
-+.TP
-+\fB\-x11cursor\fR
-+Use a real X11 cursor with X-style cursor shape updates, instead of
-+drawing the remote cursor on the framebuffer. This option also
-+disables the dot cursor, and disables cursor position updates in
-+non-fullscreen mode.
-+.TP
-+\fB\-autopass\fR
-+Read a plain-text password from stdin. This option affects only the
-+standard VNC authentication.
-+
-+.SH Enhanced TightVNC Viewer (SSVNC) OPTIONS
-+.TP
-+Enhanced TightVNC Viewer (SSVNC) web page is located at:
-+.TP
-+http://www.karlrunge.com/x11vnc/ssvnc.html
-+.TP
-+Note: ZRLE and ZYWRLE encodings are now supported.
-+.TP
-+Note: F9 is shortcut to Toggle FullScreen mode.
-+.TP
-+Note: In -listen mode set the env var. SSVNC_MULTIPLE_LISTEN=1
-+to allow more than one incoming VNC server at a time.
-+This is the same as -multilisten described below.  Set
-+SSVNC_MULTIPLE_LISTEN=MAX:n to allow no more than "n"
-+simultaneous reverse connections.
-+
-+If the host:port is specified as "exec=command args..."
-+then instead of making a TCP/IP socket connection to the
-+remote VNC server, "command args..." is executed and the
-+viewer is attached to its stdio.  This enables tunnelling
-+established via an external command, e.g. an stunnel(8)
-+that does not involve a listening socket.
-+This mode does not work for -listen reverse connections.
-+
-+If the host:port is specified as "fd=n" then it is assumed
-+n is an already opened file descriptor to the socket. (i.e
-+the parent did fork+exec)
-+
-+If the host:port contains a '/' it is interpreted as a
-+unix-domain socket (AF_LOCAL insead of AF_INET)
-+.TP
-+\fB\-multilisten\fR
-+As in -listen (reverse connection listening) except
-+allow more than one incoming VNC server to be connected
-+at a time.  The default for -listen of only one at a
-+time tries to play it safe by not allowing anyone on
-+the network to put (many) desktops on your screen over
-+a long window of time. Use -multilisten for no limit.
-+.TP
-+\fB\-acceptpopup\fR
-+In \fB\-listen\fR (reverse connection listening) mode when
-+a reverse VNC connection comes in show a popup asking
-+whether to Accept or Reject the connection.  The IP
-+address of the connecting host is shown.  Same as
-+setting the env. var. SSVNC_ACCEPT_POPUP=1.
-+.TP
-+\fB\-acceptpopupsc\fR
-+As in \fB\-acceptpopup\fR except assume UltraVNC Single
-+Click (SC) server.  Retrieve User and ComputerName
-+info from UltraVNC Server and display in the Popup.
-+.TP
-+\fB\-use64\fR
-+In \fB\-bgr233\fR mode, use 64 colors instead of 256.
-+.TP
-+\fB\-bgr222\fR
-+Same as \fB\-use64\fR.
-+.TP
-+\fB\-use8\fR
-+In \fB\-bgr233\fR mode, use 8 colors instead of 256.
-+.TP
-+\fB\-bgr111\fR
-+Same as \fB\-use8\fR.
-+.TP
-+\fB\-16bpp\fR
-+If the vnc viewer X display is depth 24 at 32bpp
-+request a 16bpp format from the VNC server to cut
-+network traffic by up to 2X, then tranlate the
-+pixels to 32bpp locally.
-+.TP
-+\fB\-bgr565\fR
-+Same as \fB\-16bpp\fR.
-+.TP
-+\fB\-grey\fR
-+Use a grey scale for the 16- and 8\fB\-bpp\fR modes.
-+.TP
-+\fB\-alpha\fR
-+Use alphablending transparency for local cursors
-+requires: x11vnc server, both client and server
-+must be 32bpp and same endianness.
-+.TP
-+\fB\-scale\fR \fIstr\fR
-+Scale the desktop locally.  The string "str" can
-+a floating point ratio, e.g. "0.9", or a fraction,
-+e.g. "3/4", or WxH, e.g. 1280x1024.  Use "fit"
-+to fit in the current screen size.  Use "auto" to
-+fit in the window size.  "str" can also be set by
-+the env. var. SSVNC_SCALE.
-+
-+If you observe mouse trail painting errors, enable
-+X11 Cursor mode (either via Popup or \fB\-x11cursor\fR.)
-+
-+Note that scaling is done in software and so can be
-+slow and requires more memory.  Some speedup Tips:
-+
-+ZRLE is faster than Tight in this mode.  When
-+scaling is first detected, the encoding will
-+be automatically switched to ZRLE.  Use the
-+Popup menu if you want to go back to Tight.
-+Set SSVNC_PRESERVE_ENCODING=1 to disable this.
-+
-+Use a solid background on the remote side.
-+(e.g. manually or via x11vnc \fB\-solid\fR ...)
-+
-+If the remote server is x11vnc, try client
-+side caching: x11vnc \fB\-ncache\fR 10 ...
-+.TP
-+\fB\-ycrop\fR n
-+Only show the top n rows of the framebuffer.  For
-+use with x11vnc \fB\-ncache\fR client caching option
-+to help "hide" the pixel cache region.
-+Use a negative value (e.g. \fB\-1\fR) for autodetection.
-+Autodetection will always take place if the remote
-+fb height is more than 2 times the width.
-+.TP
-+\fB\-sbwidth\fR n
-+Scrollbar width for x11vnc \fB\-ncache\fR mode (\fB\-ycrop\fR),
-+default is very narrow: 2 pixels, it is narrow to
-+avoid distraction in \fB\-ycrop\fR mode.
-+.TP
-+\fB\-nobell\fR
-+Disable bell.
-+.TP
-+\fB\-rawlocal\fR
-+Prefer raw encoding for localhost, default is
-+no, i.e. assumes you have a SSH tunnel instead.
-+.TP
-+\fB\-notty\fR
-+Try to avoid using the terminal for interactive
-+responses: use windows for messages and prompting
-+instead.  Messages will also be printed to terminal.
-+.TP
-+\fB\-sendclipboard\fR
-+Send the X CLIPBOARD selection (i.e. Ctrl+C,
-+Ctrl+V) instead of the X PRIMARY selection (mouse
-+select and middle button paste.)
-+.TP
-+\fB\-sendalways\fR
-+Whenever the mouse enters the VNC viewer main
-+window, send the selection to the VNC server even if
-+it has not changed.  This is like the Xt resource
-+translation SelectionToVNC(always)
-+.TP
-+\fB\-recvtext\fR
-+str   When cut text is received from the VNC server,
-+ssvncviewer will set both the X PRIMARY and the
-+X CLIPBOARD local selections.  To control which
-+is set, specify 'str' as 'primary', 'clipboard',
-+or 'both' (the default.)
-+.TP
-+\fB\-graball\fR
-+Grab the entire X server when in fullscreen mode,
-+needed by some old window managers like fvwm2.
-+.TP
-+\fB\-popupfix\fR
-+Warp the popup back to the pointer position,
-+needed by some old window managers like fvwm2.
-+.TP
-+\fB\-grabkbd\fR
-+Grab the X keyboard when in fullscreen mode,
-+needed by some window managers. Same as \fB\-grabkeyboard\fR.
-+\fB\-grabkbd\fR is the default, use \fB\-nograbkbd\fR to disable.
-+.TP
-+\fB\-bs\fR, \fB\-nobs\fR
-+Whether or not to use X server Backingstore for the
-+main viewer window.  The default is to not, mainly
-+because most Linux, etc, systems X servers disable
-+*all* Backingstore by default.  To re\fB\-enable\fR it put
-+
-+Option "Backingstore"
-+
-+in the Device section of /etc/X11/xorg.conf.
-+In \fB\-bs\fR mode with no X server backingstore, whenever an
-+area of the screen is re\fB\-exposed\fR it must go out to the
-+VNC server to retrieve the pixels. This is too slow.
-+
-+In \fB\-nobs\fR mode, memory is allocated by the viewer to
-+provide its own backing of the main viewer window. This
-+actually makes some activities faster (changes in large
-+regions) but can appear to "flash" too much.
-+.TP
-+\fB\-noshm\fR
-+Disable use of MIT shared memory extension (not recommended)
-+.TP
-+\fB\-termchat\fR
-+Do the UltraVNC chat in the terminal vncviewer is in
-+instead of in an independent window.
-+.TP
-+\fB\-unixpw\fR \fIstr\fR
-+Useful for logging into x11vnc in \fB\-unixpw\fR mode. "str" is a
-+string that allows many ways to enter the Unix Username
-+and Unix Password.  These characters: username, newline,
-+password, newline are sent to the VNC server after any VNC
-+authentication has taken place.  Under x11vnc they are
-+used for the \fB\-unixpw\fR login.  Other VNC servers could do
-+something similar.
-+
-+You can also indicate "str" via the environment
-+variable SSVNC_UNIXPW.
-+
-+Note that the Escape key is actually sent first to tell
-+x11vnc to not echo the Unix Username back to the VNC
-+viewer. Set SSVNC_UNIXPW_NOESC=1 to override this.
-+
-+If str is ".", then you are prompted at the command line
-+for the username and password in the normal way.  If str is
-+"-" the stdin is read via getpass(3) for username@password.
-+Otherwise if str is a file, it is opened and the first line
-+read is taken as the Unix username and the 2nd as the
-+password. If str prefixed by "rm:" the file is removed
-+after reading. Otherwise, if str has a "@" character,
-+it is taken as username@password. Otherwise, the program
-+exits with an error. Got all that?
-+.TP
-+\fB-repeater\fR \fIstr\fR
-+This is for use with UltraVNC repeater proxy described
-+here: http://www.uvnc.com/addons/repeater.html.  The "str"
-+is the ID string to be sent to the repeater.  E.g. ID:1234
-+It can also be the hostname and port or display of the VNC
-+server, e.g. 12.34.56.78:0 or snoopy.com:1.  Note that when
-+using -repeater, the host:dpy on the cmdline is the repeater
-+server, NOT the VNC server.  The repeater will connect you.
-+
-+Example: vncviewer ... -repeater ID:3333 repeat.host:5900
-+
-+Example: vncviewer ... -repeater vhost:0 repeat.host:5900
-+
-+Use, e.g., '-repeater SCIII=ID:3210' if the repeater is a
-+Single Click III (SSL) repeater (repeater_SSL.exe) and you
-+are passing the SSL part of the connection through stunnel, socat, etc.
-+This way the magic UltraVNC string 'testB' needed to work with the
-+repeater is sent to it.
-+.TP
-+\fB-rfbversion\fR \fIstr\fR
-+Set the advertised RFB version.  E.g.: -rfbversion 3.6  For some
-+servers, e.g. UltraVNC this needs to be done.
-+.TP
-+\fB-ultradsm\fR
-+UltraVNC has symmetric private encryption DSM plugins.  See
-+http://www.uvnc.com/features/encryption.html.  It is assumed
-+you are using a unix program (e.g. our ultravnc_dsm_helper) to
-+encrypt and decrypt the UltraVNC DSM stream. IN ADDITION TO
-+THAT supply -ultradsm to tell THIS viewer to modify the RFB
-+data sent so as to work with the UltraVNC Server.  For some
-+reason, each RFB msg type must be sent twice under DSM.
-+.TP
-+\fB\-mslogon\fR \fIuser\fR
-+Use Windows MS Logon to an UltraVNC server.  Supply the
-+username or "1" to be prompted.  The default is to
-+autodetect the UltraVNC MS Logon server and prompt for
-+the username and password.
-+
-+IMPORTANT NOTE: The UltraVNC MS-Logon Diffie-Hellman
-+exchange is very weak and can be brute forced to recover
-+your username and password in a few seconds of CPU
-+time.  To be safe, be sure to use an additional encrypted
-+tunnel (e.g. SSL or SSH) for the entire VNC session.
-+.TP
-+\fB\-chatonly\fR
-+Try to be a client that only does UltraVNC text chat. This
-+mode is used by x11vnc to present a chat window on the physical
-+X11 console (i.e. to chat with the person at the display).
-+.TP
-+\fB-env\fR \fIVAR=VALUE\fR
-+To save writing a shell script to set environment
-+variables, specify as many as you need on the command line.  For example,
-+-env SSVNC_MULTIPLE_LISTEN=MAX:5 -env EDITOR=vi
-+.TP
-+\fB\-noipv6\fR
-+Disable all IPv6 sockets.  Same as VNCVIEWER_NO_IPV6=1.
-+.TP
-+\fB\-noipv4\fR
-+Disable all IPv4 sockets.  Same as VNCVIEWER_NO_IPV4=1.
-+.TP
-+\fB\-printres\fR
-+Print out the Ssvnc X resources (appdefaults) and
-+then exit. You can save them to a file and customize them (e.g. the
-+keybindings and Popup menu)  Then point to the file via
-+XENVIRONMENT or XAPPLRESDIR.
-+.TP
-+\fB\-pipeline\fR
-+Like TurboVNC, request the next framebuffer update as soon
-+as possible instead of waiting until the end of the current
-+framebuffer update coming in.  Helps 'pipeline' the updates.
-+This is currently the default, use \fB-nopipeline\fR to disable.
-+.TP
-+\fB\-appshare\fR
-+Enable features for use with x11vnc's \fB\-appshare\fR mode where
-+instead of sharing the full desktop only the application's
-+windows are shared.  Viewer multilisten mode is used to
-+create the multiple windows: \fB\-multilisten\fR is implied.
-+See 'x11vnc \fB\-appshare\fR \fB\-help\fR' more information on the mode.
-+Features enabled in the viewer under \fB\-appshare\fR are:
-+Minimum extra text in the title, auto \fB\-ycrop\fR is disabled,
-+x11vnc \fB\-remote_prefix\fR X11VNC_APPSHARE_CMD: message channel,
-+x11vnc initial window position hints.  See also Escape Keys
-+below for additional key and mouse bindings.
-+.TP
-+\fB\-escape \fR\fIstr\fR
-+This sets the 'Escape Keys' modifier sequence and enables
-+escape keys mode.  When the modifier keys escape sequence
-+is held down, the next keystroke is interpreted locally
-+to perform a special action instead of being sent to the
-+remote VNC server.
-+
-+Use '\fB\-escape\fR default' for the default modifier sequence.
-+(Unix: Alt_L,Super_L and MacOSX: Control_L,Meta_L)
-+
-+Here are the 'Escape Keys: Help+Set' instructions from the Popup:
-+
-+Escape Keys:  Enter a comma separated list of modifier keys to be the 'escape
-+sequence'.  When these keys are held down, the next keystroke is
-+interpreted locally to invoke a special action instead of being sent to
-+the remote VNC server.  In other words, a set of 'Hot Keys'.
-+
-+Here is the list of local key mappings to special actions:
-+
-+r: refresh desktop  b: toggle bell  c: toggle full-color
-+
-+f: file transfer    x: x11cursor    z: toggle Tight/ZRLE
-+
-+l: full screen      g: graball      e: escape keys dialog
-+
-+s: scale dialog     +: scale up (=) -: scale down (_)
-+
-+t: text chat                        a: alphablend cursor
-+
-+V: toggle viewonly  Q: quit viewer  123456: UltraVNC scale 1/n
-+
-+Arrow keys: pan the viewport about 10% for each keypress.
-+
-+PageUp/PageDown: pan the viewport by a screenful vertically.
-+
-+Home/End: pan the viewport by a screenful horizontally.
-+
-+KeyPad Arrows: pan the viewport by 1 pixel for each keypress.
-+
-+Dragging the Mouse with Button1 pressed also pans the viewport.
-+
-+Clicking Mouse Button3 brings up the Popup Menu.
-+
-+The above mappings are \fBalways\fR active in ViewOnly mode, unless you set
-+the Escape Keys value to 'never'.
-+
-+x11vnc -appshare hot-keys:  x11vnc has a simple application sharing mode
-+that enables the viewer-side to move, resize, or raise the remote toplevel
-+windows.  To enable it, hold down Shift + the Escape Keys and press these:
-+
-+Arrow keys: move the remote window around in its desktop.
-+
-+PageUp/PageDn/Home/End:  resize the remote window.
-+
-++/-: raise or lower the remote window.
-+
-+M or Button1 move win to local position;  D or Button3: delete remote win.
-+
-+If the Escape Keys value below is set to 'default' then a default list of
-+of modifier keys is used.  For Unix it is: Alt_L,Super_L and for MacOSX it
-+is Control_L,Meta_L.  Note: the Super_L key usually has a Windows(TM) Flag
-+on it.  Also note the _L and _R mean the key is on the LEFT or RIGHT side
-+of the keyboard.
-+
-+On Unix   the default is Alt and Windows keys on Left side of keyboard.
-+On MacOSX the default is Control and Command keys on Left side of keyboard.
-+
-+Example: Press and hold the Alt and Windows keys on the LEFT side of the
-+keyboard and then press 'c' to toggle the full-color state.  Or press 't'
-+to toggle the ultravnc Text Chat window, etc.
-+
-+To use something besides the default, supply a comma separated list (or a
-+single one) from: Shift_L Shift_R Control_L Control_R Alt_L Alt_R Meta_L
-+Meta_R Super_L Super_R Hyper_L Hyper_R or Mode_switch.

-+VNC is sent as rectangles). All rectangles come with a header giving
-+the location and size of the rectangle and an encoding type used by
-+the data which follows. These types are listed below.
-+.TP
-+.B Raw
-+The raw encoding simply sends width*height pixel values. All clients
-+are required to support this encoding type. Raw is also the fastest
-+when the server and viewer are on the same machine, as the connection
-+speed is essentially infinite and raw encoding minimizes processing
-+time.
-+.TP
-+.B CopyRect
-+The Copy Rectangle encoding is efficient when something is being
-+moved; the only data sent is the location of a rectangle from which
-+data should be copied to the current location. Copyrect could also be
-+used to efficiently transmit a repeated pattern.
-+.TP
-+.B RRE
-+The Rise\-and\-Run\-length\-Encoding is basically a 2D version of
-+run\-length encoding (RLE). In this encoding, a sequence of identical
-+pixels are compressed to a single value and repeat count. In VNC, this
-+is implemented with a background color, and then specifications of an
-+arbitrary number of subrectangles and color for each. This is an
-+efficient encoding for large blocks of constant color.
-+.TP
-+.B CoRRE
-+This is a minor variation on RRE, using a maximum of 255x255 pixel
-+rectangles. This allows for single\-byte values to be used, reducing
-+packet size. This is in general more efficient, because the savings
-+from sending 1\-byte values generally outweighs the losses from the
-+(relatively rare) cases where very large regions are painted the same
-+color.
-+.TP
-+.B Hextile
-+Here, rectangles are split up in to 16x16 tiles, which are sent in a
-+predetermined order. The data within the tiles is sent either raw or
-+as a variant on RRE. Hextile encoding is usually the best choice for
-+using in high\-speed network environments (e.g. Ethernet local\-area
-+networks).
-+.TP
-+.B Zlib
-+Zlib is a very simple encoding that uses zlib library to compress raw
-+pixel data. This encoding achieves good compression, but consumes a
-+lot of CPU time. Support for this encoding is provided for
-+compatibility with VNC servers that might not understand Tight
-+encoding which is more efficient than Zlib in nearly all real\-life
-+situations.
-+.TP
-+.B Tight
-+Like Zlib encoding, Tight encoding uses zlib library to compress the
-+pixel data, but it pre\-processes data to maximize compression ratios,
-+and to minimize CPU usage on compression. Also, JPEG compression may
-+be used to encode color\-rich screen areas (see the description of
-+\-quality and \-nojpeg options above). Tight encoding is usually the
-+best choice for low\-bandwidth network environments (e.g. slow modem
-+connections).
-+.TP
-+.B ZRLE
-+The SSVNC viewer has ported the RealVNC (www.realvnc.com) ZRLE encoding
-+to the unix tightvnc viewer.
-+.TP
-+.B ZYWRLE
-+The SSVNC viewer has ported the Hitachi lossy wavelet based ZRLE
-+encoding from http://mobile.hitachi-system.co.jp/publications/ZYWRLE/ 
-+to the unix tightvnc viewer.
-+.SH RESOURCES
-+X resources that \fBvncviewer\fR knows about, aside from the
-+normal Xt resources, are as follows:
-+.TP
-+.B shareDesktop
-+Equivalent of \fB\-shared\fR/\fB\-noshared\fR options. Default true.
-+.TP
-+.B viewOnly
-+Equivalent of \fB\-viewonly\fR option. Default false.
-+.TP
-+.B fullScreen
-+Equivalent of \fB\-fullscreen\fR option. Default false.
-+.TP
-+.B grabKeyboard
-+Grab keyboard in full-screen mode. This can help to solve problems
-+with losing keyboard focus. Default false.
-+.TP
-+.B raiseOnBeep
-+Equivalent of \fB\-noraiseonbeep\fR option, when set to false. Default
-+true.
-+.TP
-+.B passwordFile
-+Equivalent of \fB\-passwd\fR option.
-+.TP
-+.B userLogin
-+Equivalent of \fB\-user\fR option.
-+.TP
-+.B passwordDialog
-+Whether to use a dialog box to get the password (true) or get it from
-+the tty (false). Irrelevant if \fBpasswordFile\fR is set. Default
-+false.
-+.TP
-+.B encodings
-+Equivalent of \fB\-encodings\fR option.
-+.TP
-+.B compressLevel
-+Equivalent of \fB\-compresslevel\fR option (TightVNC\-specific).
-+.TP
-+.B qualityLevel
-+Equivalent of \fB\-quality\fR option (TightVNC\-specific).
-+.TP
-+.B enableJPEG
-+Equivalent of \fB\-nojpeg\fR option, when set to false. Default true.
-+.TP
-+.B useRemoteCursor
-+Equivalent of \fB\-nocursorshape\fR option, when set to false
-+(TightVNC\-specific). Default true.
-+.TP
-+.B useBGR233
-+Equivalent of \fB\-bgr233\fR option. Default false.
-+.TP
-+.B nColours
-+When using BGR233, try to allocate this many "exact" colors from the
-+BGR233 color cube. When using a shared colormap, setting this resource
-+lower leaves more colors for other X clients. Irrelevant when using
-+truecolor. Default is 256 (i.e. all of them).
-+.TP
-+.B useSharedColours
-+If the number of "exact" BGR233 colors successfully allocated is less
-+than 256 then the rest are filled in using the "nearest" colors
-+available. This resource says whether to only use the "exact" BGR233
-+colors for this purpose, or whether to use other clients' "shared"
-+colors as well. Default true (i.e. use other clients' colors).
-+.TP
-+.B forceOwnCmap
-+Equivalent of \fB\-owncmap\fR option. Default false.
-+.TP
-+.B forceTrueColour
-+Equivalent of \fB\-truecolour\fR option. Default false.
-+.TP
-+.B requestedDepth
-+Equivalent of \fB\-depth\fR option.
-+.TP
-+.B useSharedMemory
-+Use MIT shared memory extension if on the same machine as the X
-+server. Default true.
-+.TP
-+.B wmDecorationWidth, wmDecorationHeight
-+The total width and height taken up by window manager decorations.
-+This is used to calculate the maximum size of the VNC viewer window. 
-+Default is width 4, height 24.
-+.TP
-+.B bumpScrollTime, bumpScrollPixels
-+When in full screen mode and the VNC desktop is bigger than the X
-+display, scrolling happens whenever the mouse hits the edge of the
-+screen. The maximum speed of scrolling is bumpScrollPixels pixels
-+every bumpScrollTime milliseconds. The actual speed of scrolling will
-+be slower than this, of course, depending on how fast your machine is. 
-+Default 20 pixels every 25 milliseconds.
-+.TP
-+.B popupButtonCount
-+The number of buttons in the popup window. See the README file for
-+more information on how to customize the buttons.
-+.TP
-+.B debug
-+For debugging. Default false.
-+.TP
-+.B rawDelay, copyRectDelay
-+For debugging, see the README file for details. Default 0 (off).
-+.SH ENVIRONMENT
-+When started with the \fB\-via\fR option, vncviewer reads the
-+\fBVNC_VIA_CMD\fR environment variable, expands patterns beginning
-+with the "%" character, and executes result as a command assuming that
-+it would create TCP tunnel that should be used for VNC connection. If
-+not set, this environment variable defaults to "/usr/bin/ssh -f -L
-+%L:%H:%R %G sleep 20".
-+
-+The following patterns are recognized in the \fBVNC_VIA_CMD\fR (note
-+that all the patterns %G, %H, %L and %R must be present in the command
-+template):
-+.TP
-+.B %%
-+A literal "%";
-+.TP
-+.B %G
-+gateway host name;
-+.TP
-+.B %H
-+remote VNC host name, as known to the gateway;
-+.TP
-+.B %L
-+local TCP port number;
-+.TP
-+.B %R
-+remote TCP port number.

-+.SH Enhanced TightVNC Viewer (SSVNC) OPTIONS
-+.TP
-+Enhanced TightVNC Viewer (SSVNC) web page is located at:
-+.TP
-+http://www.karlrunge.com/x11vnc/ssvnc.html
-+.TP
-+Note: ZRLE and ZYWRLE encodings are now supported.
-+.TP
-+Note: F9 is shortcut to Toggle FullScreen mode.
-+.TP
-+Note: In -listen mode set the env var. SSVNC_MULTIPLE_LISTEN=1
-+to allow more than one incoming VNC server at a time.
-+This is the same as -multilisten described below.  Set
-+SSVNC_MULTIPLE_LISTEN=MAX:n to allow no more than "n"
-+simultaneous reverse connections.
-+
-+If the host:port is specified as "exec=command args..."
-+then instead of making a TCP/IP socket connection to the
-+remote VNC server, "command args..." is executed and the
-+viewer is attached to its stdio.  This enables tunnelling
-+established via an external command, e.g. an stunnel(8)
-+that does not involve a listening socket.
-+This mode does not work for -listen reverse connections.
-+
-+If the host:port is specified as "fd=n" then it is assumed
-+n is an already opened file descriptor to the socket. (i.e
-+the parent did fork+exec)
-+
-+If the host:port contains a '/' it is interpreted as a
-+unix-domain socket (AF_LOCAL insead of AF_INET)
-+.TP
-+\fB\-multilisten\fR
-+As in -listen (reverse connection listening) except
-+allow more than one incoming VNC server to be connected
-+at a time.  The default for -listen of only one at a
-+time tries to play it safe by not allowing anyone on
-+the network to put (many) desktops on your screen over
-+a long window of time. Use -multilisten for no limit.
-+.TP
-+\fB\-acceptpopup\fR
-+In \fB\-listen\fR (reverse connection listening) mode when
-+a reverse VNC connection comes in show a popup asking
-+whether to Accept or Reject the connection.  The IP
-+address of the connecting host is shown.  Same as
-+setting the env. var. SSVNC_ACCEPT_POPUP=1.
-+.TP
-+\fB\-acceptpopupsc\fR
-+As in \fB\-acceptpopup\fR except assume UltraVNC Single
-+Click (SC) server.  Retrieve User and ComputerName
-+info from UltraVNC Server and display in the Popup.
-+.TP
-+\fB\-use64\fR
-+In \fB\-bgr233\fR mode, use 64 colors instead of 256.
-+.TP
-+\fB\-bgr222\fR
-+Same as \fB\-use64\fR.
-+.TP
-+\fB\-use8\fR
-+In \fB\-bgr233\fR mode, use 8 colors instead of 256.
-+.TP
-+\fB\-bgr111\fR
-+Same as \fB\-use8\fR.
-+.TP
-+\fB\-16bpp\fR
-+If the vnc viewer X display is depth 24 at 32bpp
-+request a 16bpp format from the VNC server to cut
-+network traffic by up to 2X, then tranlate the
-+pixels to 32bpp locally.
-+.TP
-+\fB\-bgr565\fR
-+Same as \fB\-16bpp\fR.
-+.TP
-+\fB\-grey\fR
-+Use a grey scale for the 16- and 8\fB\-bpp\fR modes.
-+.TP
-+\fB\-alpha\fR
-+Use alphablending transparency for local cursors
-+requires: x11vnc server, both client and server
-+must be 32bpp and same endianness.
-+.TP
-+\fB\-scale\fR \fIstr\fR
-+Scale the desktop locally.  The string "str" can
-+a floating point ratio, e.g. "0.9", or a fraction,
-+e.g. "3/4", or WxH, e.g. 1280x1024.  Use "fit"
-+to fit in the current screen size.  Use "auto" to
-+fit in the window size.  "str" can also be set by
-+the env. var. SSVNC_SCALE.
-+
-+If you observe mouse trail painting errors, enable
-+X11 Cursor mode (either via Popup or \fB\-x11cursor\fR.)
-+
-+Note that scaling is done in software and so can be
-+slow and requires more memory.  Some speedup Tips:
-+
-+ZRLE is faster than Tight in this mode.  When
-+scaling is first detected, the encoding will
-+be automatically switched to ZRLE.  Use the
-+Popup menu if you want to go back to Tight.
-+Set SSVNC_PRESERVE_ENCODING=1 to disable this.
-+
-+Use a solid background on the remote side.
-+(e.g. manually or via x11vnc \fB\-solid\fR ...)
-+
-+If the remote server is x11vnc, try client
-+side caching: x11vnc \fB\-ncache\fR 10 ...
-+.TP
-+\fB\-ycrop\fR n
-+Only show the top n rows of the framebuffer.  For
-+use with x11vnc \fB\-ncache\fR client caching option
-+to help "hide" the pixel cache region.
-+Use a negative value (e.g. \fB\-1\fR) for autodetection.
-+Autodetection will always take place if the remote
-+fb height is more than 2 times the width.
-+.TP
-+\fB\-sbwidth\fR n
-+Scrollbar width for x11vnc \fB\-ncache\fR mode (\fB\-ycrop\fR),
-+default is very narrow: 2 pixels, it is narrow to
-+avoid distraction in \fB\-ycrop\fR mode.
-+.TP
-+\fB\-nobell\fR
-+Disable bell.
-+.TP
-+\fB\-rawlocal\fR
-+Prefer raw encoding for localhost, default is
-+no, i.e. assumes you have a SSH tunnel instead.
-+.TP
-+\fB\-notty\fR
-+Try to avoid using the terminal for interactive
-+responses: use windows for messages and prompting
-+instead.  Messages will also be printed to terminal.
-+.TP
-+\fB\-sendclipboard\fR
-+Send the X CLIPBOARD selection (i.e. Ctrl+C,
-+Ctrl+V) instead of the X PRIMARY selection (mouse
-+select and middle button paste.)
-+.TP
-+\fB\-sendalways\fR
-+Whenever the mouse enters the VNC viewer main
-+window, send the selection to the VNC server even if
-+it has not changed.  This is like the Xt resource
-+translation SelectionToVNC(always)
-+.TP
-+\fB\-recvtext\fR
-+str   When cut text is received from the VNC server,
-+ssvncviewer will set both the X PRIMARY and the
-+X CLIPBOARD local selections.  To control which
-+is set, specify 'str' as 'primary', 'clipboard',
-+or 'both' (the default.)
-+.TP
-+\fB\-graball\fR
-+Grab the entire X server when in fullscreen mode,
-+needed by some old window managers like fvwm2.
-+.TP
-+\fB\-popupfix\fR
-+Warp the popup back to the pointer position,
-+needed by some old window managers like fvwm2.
-+.TP
-+\fB\-grabkbd\fR
-+Grab the X keyboard when in fullscreen mode,
-+needed by some window managers. Same as \fB\-grabkeyboard\fR.
-+\fB\-grabkbd\fR is the default, use \fB\-nograbkbd\fR to disable.
-+.TP
-+\fB\-bs\fR, \fB\-nobs\fR
-+Whether or not to use X server Backingstore for the
-+main viewer window.  The default is to not, mainly
-+because most Linux, etc, systems X servers disable
-+*all* Backingstore by default.  To re\fB\-enable\fR it put
-+
-+Option "Backingstore"
-+
-+in the Device section of /etc/X11/xorg.conf.
-+In \fB\-bs\fR mode with no X server backingstore, whenever an
-+area of the screen is re\fB\-exposed\fR it must go out to the
-+VNC server to retrieve the pixels. This is too slow.
-+
-+In \fB\-nobs\fR mode, memory is allocated by the viewer to
-+provide its own backing of the main viewer window. This
-+actually makes some activities faster (changes in large
-+regions) but can appear to "flash" too much.
-+.TP
-+\fB\-noshm\fR
-+Disable use of MIT shared memory extension (not recommended)
-+.TP
-+\fB\-termchat\fR
-+Do the UltraVNC chat in the terminal vncviewer is in
-+instead of in an independent window.
-+.TP
-+\fB\-unixpw\fR \fIstr\fR
-+Useful for logging into x11vnc in \fB\-unixpw\fR mode. "str" is a
-+string that allows many ways to enter the Unix Username
-+and Unix Password.  These characters: username, newline,
-+password, newline are sent to the VNC server after any VNC
-+authentication has taken place.  Under x11vnc they are
-+used for the \fB\-unixpw\fR login.  Other VNC servers could do
-+something similar.
-+
-+You can also indicate "str" via the environment
-+variable SSVNC_UNIXPW.
-+
-+Note that the Escape key is actually sent first to tell
-+x11vnc to not echo the Unix Username back to the VNC
-+viewer. Set SSVNC_UNIXPW_NOESC=1 to override this.
-+
-+If str is ".", then you are prompted at the command line
-+for the username and password in the normal way.  If str is
-+"-" the stdin is read via getpass(3) for username@password.
-+Otherwise if str is a file, it is opened and the first line
-+read is taken as the Unix username and the 2nd as the
-+password. If str prefixed by "rm:" the file is removed
-+after reading. Otherwise, if str has a "@" character,
-+it is taken as username@password. Otherwise, the program
-+exits with an error. Got all that?
-+.TP
-+\fB-repeater\fR \fIstr\fR
-+This is for use with UltraVNC repeater proxy described
-+here: http://www.uvnc.com/addons/repeater.html.  The "str"
-+is the ID string to be sent to the repeater.  E.g. ID:1234
-+It can also be the hostname and port or display of the VNC
-+server, e.g. 12.34.56.78:0 or snoopy.com:1.  Note that when
-+using -repeater, the host:dpy on the cmdline is the repeater
-+server, NOT the VNC server.  The repeater will connect you.
-+
-+Example: vncviewer ... -repeater ID:3333 repeat.host:5900
-+
-+Example: vncviewer ... -repeater vhost:0 repeat.host:5900
-+
-+Use, e.g., '-repeater SCIII=ID:3210' if the repeater is a
-+Single Click III (SSL) repeater (repeater_SSL.exe) and you
-+are passing the SSL part of the connection through stunnel, socat, etc.
-+This way the magic UltraVNC string 'testB' needed to work with the
-+repeater is sent to it.
-+.TP
-+\fB-rfbversion\fR \fIstr\fR
-+Set the advertised RFB version.  E.g.: -rfbversion 3.6  For some
-+servers, e.g. UltraVNC this needs to be done.
-+.TP
-+\fB-ultradsm\fR
-+UltraVNC has symmetric private encryption DSM plugins.  See
-+http://www.uvnc.com/features/encryption.html.  It is assumed
-+you are using a unix program (e.g. our ultravnc_dsm_helper) to
-+encrypt and decrypt the UltraVNC DSM stream. IN ADDITION TO
-+THAT supply -ultradsm to tell THIS viewer to modify the RFB
-+data sent so as to work with the UltraVNC Server.  For some
-+reason, each RFB msg type must be sent twice under DSM.
-+.TP
-+\fB\-mslogon\fR \fIuser\fR
-+Use Windows MS Logon to an UltraVNC server.  Supply the
-+username or "1" to be prompted.  The default is to
-+autodetect the UltraVNC MS Logon server and prompt for
-+the username and password.
-+
-+IMPORTANT NOTE: The UltraVNC MS-Logon Diffie-Hellman
-+exchange is very weak and can be brute forced to recover
-+your username and password in a few seconds of CPU
-+time.  To be safe, be sure to use an additional encrypted
-+tunnel (e.g. SSL or SSH) for the entire VNC session.
-+.TP
-+\fB\-chatonly\fR
-+Try to be a client that only does UltraVNC text chat. This
-+mode is used by x11vnc to present a chat window on the physical
-+X11 console (i.e. to chat with the person at the display).
-+.TP
-+\fB-env\fR \fIVAR=VALUE\fR
-+To save writing a shell script to set environment
-+variables, specify as many as you need on the command line.  For example,
-+-env SSVNC_MULTIPLE_LISTEN=MAX:5 -env EDITOR=vi
-+.TP
-+\fB\-noipv6\fR
-+Disable all IPv6 sockets.  Same as VNCVIEWER_NO_IPV6=1.
-+.TP
-+\fB\-noipv4\fR
-+Disable all IPv4 sockets.  Same as VNCVIEWER_NO_IPV4=1.
-+.TP
-+\fB\-printres\fR
-+Print out the Ssvnc X resources (appdefaults) and
-+then exit. You can save them to a file and customize them (e.g. the
-+keybindings and Popup menu)  Then point to the file via
-+XENVIRONMENT or XAPPLRESDIR.
-+.TP
-+\fB\-pipeline\fR
-+Like TurboVNC, request the next framebuffer update as soon
-+as possible instead of waiting until the end of the current
-+framebuffer update coming in.  Helps 'pipeline' the updates.
-+This is currently the default, use \fB-nopipeline\fR to disable.
-+.TP
-+\fB\-appshare\fR
-+Enable features for use with x11vnc's \fB\-appshare\fR mode where
-+instead of sharing the full desktop only the application's
-+windows are shared.  Viewer multilisten mode is used to
-+create the multiple windows: \fB\-multilisten\fR is implied.
-+See 'x11vnc \fB\-appshare\fR \fB\-help\fR' more information on the mode.
-+Features enabled in the viewer under \fB\-appshare\fR are:
-+Minimum extra text in the title, auto \fB\-ycrop\fR is disabled,
-+x11vnc \fB\-remote_prefix\fR X11VNC_APPSHARE_CMD: message channel,
-+x11vnc initial window position hints.  See also Escape Keys
-+below for additional key and mouse bindings.
-+.TP
-+\fB\-escape \fR\fIstr\fR
-+This sets the 'Escape Keys' modifier sequence and enables
-+escape keys mode.  When the modifier keys escape sequence
-+is held down, the next keystroke is interpreted locally
-+to perform a special action instead of being sent to the
-+remote VNC server.
-+
-+Use '\fB\-escape\fR default' for the default modifier sequence.
-+(Unix: Alt_L,Super_L and MacOSX: Control_L,Meta_L)
-+
-+Here are the 'Escape Keys: Help+Set' instructions from the Popup:
-+
-+Escape Keys:  Enter a comma separated list of modifier keys to be the 'escape
-+sequence'.  When these keys are held down, the next keystroke is
-+interpreted locally to invoke a special action instead of being sent to
-+the remote VNC server.  In other words, a set of 'Hot Keys'.
-+
-+Here is the list of local key mappings to special actions:
-+
-+r: refresh desktop  b: toggle bell  c: toggle full-color
-+
-+f: file transfer    x: x11cursor    z: toggle Tight/ZRLE
-+
-+l: full screen      g: graball      e: escape keys dialog
-+
-+s: scale dialog     +: scale up (=) -: scale down (_)
-+
-+t: text chat                        a: alphablend cursor
-+
-+V: toggle viewonly  Q: quit viewer  123456: UltraVNC scale 1/n
-+
-+Arrow keys: pan the viewport about 10% for each keypress.
-+
-+PageUp/PageDown: pan the viewport by a screenful vertically.
-+

-+
-+Arrow keys: move the remote window around in its desktop.
-+
-+PageUp/PageDn/Home/End:  resize the remote window.

-+
-+If the Escape Keys value below is set to 'default' then a default list of
-+of modifier keys is used.  For Unix it is: Alt_L,Super_L and for MacOSX it
-+is Control_L,Meta_L.  Note: the Super_L key usually has a Windows(TM) Flag
-+on it.  Also note the _L and _R mean the key is on the LEFT or RIGHT side
-+of the keyboard.
-+
-+On Unix   the default is Alt and Windows keys on Left side of keyboard.
-+On MacOSX the default is Control and Command keys on Left side of keyboard.
-+
-+Example: Press and hold the Alt and Windows keys on the LEFT side of the
-+keyboard and then press 'c' to toggle the full-color state.  Or press 't'
-+to toggle the ultravnc Text Chat window, etc.
-+
-+To use something besides the default, supply a comma separated list (or a

-+ Type B:Non liner quantization filter.
-+
-+ Coefficients have Gaussian curve and smaller value which is
-+ large part of coefficients isn't more important than larger value.
-+ So, I use filter of Non liner quantize/dequantize table.
-+ In general, Non liner quantize formula is explained as following.
-+
-+    y=f(x)   = sign(x)*round( ((abs(x)/(2^7))^ r   )* 2^(bo-1) )*2^(8-bo)
-+    x=f-1(y) = sign(y)*round( ((abs(y)/(2^7))^(1/r))* 2^(bi-1) )*2^(8-bi)
-+ ( r:power coefficient  bi:effective MSB in input  bo:effective MSB in output )
-+
-+   r < 1.0 : Smaller value is more important than larger value.
-+   r > 1.0 : Larger value is more important than smaller value.
-+   r = 1.0 : Liner quantization which is same with EZW style.
-+
-+ r = 0.75 is famous non liner quantization used in MP3 audio codec.
-+ In contrast to audio data, larger value is important in wavelet coefficients.
-+ So, I select r = 2.0 table( quantize is x^2, dequantize sqrt(x) ).
-+
-+ As compared with EZW style liner quantization, this filter tended to be
-+ more sharp edge and be more compression rate but be more blocking noise and be less quality.
-+ Especially, the surface of graphic objects has distinguishable noise in middle quality mode.
-+
-+ We need only quantized-dequantized(filtered) value rather than quantized value itself
-+ because all values are packed or palette-lized in later ZRLE section.
-+ This lead us not to need to modify client decoder when we change
-+ the filtering procedure in future.
-+ Client only decodes coefficients given by encoder.

-INTRO:
-------
-
-This is a "patch" to make x11vnc/libvncserver work with TurboVNC:
-
-	http://www.virtualgl.org/About/TurboVNC
-	http://www.karlrunge.com/x11vnc/faq.html#faq-turbovnc
-
-It is very experimental/kludgy.  Not all TurboVNC features may be enabled.
-We are currently evaluating whether TurboVNC support should be officially
-put into x11vnc/libvncserver.
-
-TurboVNC is an optimized VNC for fast refresh rates on fast networks.
-
-It does pretty well on good broadband as well.  But it is not as fast
-as regular TightVNC on slow links.
-
-
-TURBOJPEG:
----------
-
-TurboVNC uses the TurboJPEG library based on a fast proprietary JPEG
-implementation.  You will need to download it from the VirtualGL
-sourceforge site:
-
-	http://sourceforge.net/project/showfiles.php?group_id=117509&package_id=166100
-
-Either install it or simply unpack the .deb or .rpm file into a directory.
-
-N.B. you can unpack a .deb via 'ar x package.deb' and the extracting
-from the data.tar.gz file.  rpm2cpio can be used to unpack .rpm's.
-
-
-QUICK-START:
-------------
-
-For those in a hurry:
-
-  cd x11vnc-x.y.z/x11vnc/misc/turbovnc
-  ./apply_turbovnc
-  cd ../../..
-  env LDFLAGS='-L/DIR -Xlinker --rpath=/DIR' ./configure
-  make AM_LDFLAGS='-lturbojpeg'
-
-where you replace /DIR with your directory containing libturbojpeg.so.
-
-
-PATCHING AND BUILDING:
-----------------------
-
-After unpacking your x11vnc-x.y.z.tar.gz tarball cd to the
-x11vnc-x.y.z/x11vnc/misc/turbovnc (where this README file is) and from
-that directory run:
-
-	./apply_turbovnc
-
-that will modify files in the libvncserver and x11vnc directories above
-this directory.  (To undo these changes run: ./undo_turbovnc)  The input
-sources, tight.c and turbojpeg.h are from the TurboVNC source package.
-
-After applying, go back to the top level source directory and run:
-
-	env LDFLAGS='-L/path/to/turbojpeg -Xlinker --rpath=/path/to/turbojpeg' ./configure 
-
-where the turbojpeg library is:
-
-	/path/to/turbojpeg/libturbojpeg.so
-
-(change /path/to/turbojpeg to the directory where you installed or
-unpacked it.)
-
-If you are not using gnu gcc and gnu linker the options may be a little
-different (e.g. -R instead of -Xlinker --rpath).
-
-If you need additional ./configure options or env. var. settings,
-add them too.
-
-
-Next, run this make command:
-
-	make AM_LDFLAGS='-lturbojpeg'
-
-This is a hack and may not always work, if it doesn't edit x11vnc/Makefile
-and add '-lturbojpeg' to the LIBS variable.
-
-This should create a binary:
-
-	./x11vnc/x11vnc
-
-that supports VirtualGL's TurboVNC.
-
-You will need a TurboVNC viewer, you can get one here:
-
-	http://sourceforge.net/project/showfiles.php?group_id=117509&package_id=128130
-
-Let us know how it goes.
-
-
-PERFORMANCE:
-------------
-
-Note that x11vnc has to read the display's screen pixels from the
-graphics card memory.  This can be slow, e.g. 10 MB/sec.
-
-There is not a big need for graphics card manufacturers to optimize the
-read rate; the write rate is the one they optimize greatly.
-
-	http://www.karlrunge.com/x11vnc/#limitations
-
-If you run x11vnc and see lines like this:
-
-    28/02/2009 00:52:07 Autoprobing selected port 5900
-    28/02/2009 00:52:07 fb read rate: 10 MB/sec
-    28/02/2009 00:52:07 screen setup finished.
-
-you have a typical slow one.
-
-Whereas if you see this:
-
-    28/02/2009 00:54:46 Autoprobing selected port 5900
-    28/02/2009 00:54:46 fb read rate: 321 MB/sec
-    28/02/2009 00:54:46 fast read: reset wait  ms to: 10
-    28/02/2009 00:54:46 fast read: reset defer ms to: 10
-    28/02/2009 00:54:46 screen setup finished.
-
-that is very fast.  In such a situation you may want to dial down
-x11vnc's delay, e.g.:  -wait 5 -defer 5, or even smaller to push things
-out more quickly.
-
-We have only seen it this fast on Linux by using the nvidia proprietary
-graphics drivers.  The Xorg drivers are typically slow 10 MB/sec.
-
-It will also be fast if the X server is virtual: Xvfb or Xdummy
-since the screen pixels are stored in RAM:
-
-	http://www.karlrunge.com/x11vnc/faq.html#faq-xvfb
-
-And it will be fast if the ShadowFB xorg.conf option is enabled (if the
-card supports it.)
-
-
-The point we are trying to make is that even though TurboVNC uses a
-wicked fast JPEG implementation, and cuts out overhead in its attempt to
-pump out as many frames per second as it can, if it is slow for x11vnc
-to read the screen pixels in the first place then you might not even
-notice the TurboVNC speedup.
-
-So TurboVNC+x11vnc will be faster than TightVNC+x11vnc, but if there is
-a large overhead/bottleneck from reading the graphics card framebuffer,
-then the speedup will be marginal.

-     When the image is converted from the RGB to YCbCr colorspace as part of the

-     discarded to produce a smaller image with little perceptible loss of
-     image clarity (the human eye is more sensitive to small changes in
-     brightness than small changes in color.)

-        horizontal and vertical directions.
-     TJ_422: 4:2:2 subsampling.  Discards every other Cb, Cr pixel only in
-        the horizontal direction.

-  [INPUT] flags = the bitwise OR of one or more of the following

-ultravnc_repeater.pl:
-          perl script implementing the ultravnc repeater
-          proxy protocol.
-
-protocol: Listen on one port for vnc clients (default 5900.)
-          Listen on one port for vnc servers (default 5500.)
-          Read 250 bytes from connecting vnc client or server.
-          Accept ID:<string> from clients and servers, connect them
-          together once both are present.
-
-          The string "RFB 000.000\n" is sent to the client (the client
-          must understand this means send ID:... or host:port.)
-          Also accept <host>:<port> from clients and make the
-          connection to the vnc server immediately. 
-
-          Note there is no authentication or security WRT ID names or
-          identities; it is up to the client and server to completely
-          manage that aspect and whether to encrypt the session, etc.
-
-usage:  ultravnc_repeater.pl [-r] [client_port [server_port]]
-
-Use -r to refuse new server/client connections when there is an existing
-server/client ID.  The default is to close the previous one.
-
-To write to a log file set the env. var ULTRAVNC_REPEATER_LOGFILE.
-
-To run in a loop restarting the server if it exits set the env. var.
-ULTRAVNC_REPEATER_LOOP=1 or ULTRAVNC_REPEATER_LOOP=BG, the latter
-forks into the background.  Set ULTRAVNC_REPEATER_PIDFILE to a file
-to store the master pid in.
-
-Set ULTRAVNC_REPEATER_NO_RFB=1 to disable sending "RFB 000.000" to
-the client.  Then this program acts as general TCP rendezvous tool.

-"# Pointer <client#> <x> <y> <mask> <hint>\n"
-"#\n"
-"#\n"
-"# The <client#> is a decimal integer uniquely identifying the client\n"
-"# that generated the event.  If it is negative that means this event\n"
-"# would have been discarded since the client was viewonly.\n"
-"#\n"
-"# <x> and <y> are decimal integers reflecting the position on the screen\n"
-"# the event took place at.\n"
-"#\n"
-"# <mask> is the button mask indicating the button press state, as normal\n"
-"# 0 means no buttons pressed, 1 means button 1 is down 3 (11) means buttons\n"
-"# 1 and 2 are down, etc.\n"
-"#\n"
-"# <hint> is a string containing no spaces and may be ignored.\n"
-"# It contains some interpretation about what has happened.\n"
-"# It can be:\n"
-"#\n"
-"#	None		(nothing to report)\n"
-"#	ButtonPress-N	(this event will cause button-N to be pressed) \n"
-"#	ButtonRelease-N	(this event will cause button-N to be released) \n"
-"#\n"
-"# if two more more buttons change state in one event they are listed\n"
-"# separated by commas.\n"
-"#\n"
-"# One might parse a Pointer line with:\n"
-"#\n"
-"# int client, x, y, mask; char hint[100];\n"
-"# sscanf(line, \"Pointer %d %d %d %d %s\", &client, &x, &y, &mask, hint);\n"
-"#\n"
-"#\n"
-"# Keysym events (keyboard presses and releases) come in the form:\n"
-"#\n"
-"#\n"
-"# Keysym <client#> <down> <keysym#> <keysym-name> <hint>\n"
-"#\n"
-"#\n"
-"# The <client#> is as with Pointer.\n"
-"#\n"
-"# <down> is a decimal either 1 or 0 indicating KeyPress or KeyRelease,\n"
-"# respectively.\n"
-"#\n"
-"# <keysym#> is a decimal integer incidating the Keysym of the event.\n"
-"#\n"
-"# <keysym-name> is the corresponding Keysym name.\n"
-"#\n"
-"# See the file /usr/include/X11/keysymdef.h for the mappings.\n"
-"# You basically remove the leading 'XK_' prefix from the macro name in\n"
-"# that file to get the Keysym name.\n"
-"#\n"
-"# One might parse a Keysym line with:\n"
-"#\n"
-"# int client, down, keysym; char name[100], hint[100];\n"
-"# sscanf(line, \"Keysym %d %d %d %s %s\", &client, &down, &keysym, name, hint);\n"
-"#\n"
-"# The <hint> value is currently just None, KeyPress, or KeyRelease.\n"
-"#\n"
-"# In the future <hint> will provide a hint for the sequence of KeyCodes\n"
-"# (i.e. keyboard scancodes) that x11vnc would inject to an X display to\n"
-"# simulate the Keysym.\n"
-"#\n"
-"# You see, some Keysyms will require more than one injected Keycode to\n"
-"# generate the symbol.  E.g. the Keysym \"ampersand\" going down usually\n"
-"# requires a Shift key going down, then the key with the \"&\" on it going\n"
-"# down, and, perhaps, the Shift key going up (that is how x11vnc does it).\n"
-"#\n"
-"# The Keysym => Keycode(s) stuff gets pretty messy.  Hopefully the Keysym\n"
-"# info will be enough for most purposes (having identical keyboards on\n"
-"# both sides helps).\n"

- * Scaling:
- *
- * For shrinking, a destination (scaled) pixel will correspond to more
- * than one source (i.e. main fb) pixel.  Think of an x-y plane made with
- * graph paper.  Each unit square in the graph paper (i.e. collection of
- * points (x,y) such that N < x < N+1 and M < y < M+1, N and M integers)
- * corresponds to one pixel in the unscaled fb.  There is a solid
- * color filling the inside of such a square.  A scaled pixel has width
- * 1/scale_fac, e.g. for "-scale 3/4" the width of the scaled pixel
- * is 1.333.  The area of this scaled pixel is 1.333 * 1.333 (so it
- * obviously overlaps more than one source pixel, each which have area 1).
- *
- * We take the weight an unscaled pixel (source) contributes to a
- * scaled pixel (destination) as simply proportional to the overlap area
- * between the two pixels.  One can then think of the value of the scaled
- * pixel as an integral over the portion of the graph paper it covers.
- * The thing being integrated is the color value of the unscaled source.
- * That color value is constant over a graph paper square (source pixel),
- * and changes discontinuously from one unit square to the next.
- *
-
-Here is an example for -scale 3/4, the solid lines are the source pixels
-(graph paper unit squares), while the dotted lines denote the scaled
-pixels (destination pixels):

-So we see the first scaled pixel (0 < x < 4/3 and 0 < y < 4/3) mostly
-overlaps with unscaled source pixel "A".  The integration (averaging)
-weights for this scaled pixel are:
-
-			A	 1
-			B	1/3
-			C	1/3
-			D	1/9
-
- *
- * The Red, Green, and Blue color values must be averaged over separately
- * otherwise you can get a complete mess (except in solid regions),
- * because high order bits are averaged differently from the low order bits.
- *
- * So the algorithm is roughly:
- *
- *   - Given as input a rectangle in the unscaled source fb with changes,
- *     find the rectangle of pixels this affects in the scaled destination fb.
- *
- *   - For each of the affected scaled (dest) pixels, determine all of the
- *     unscaled (source) pixels it overlaps with.
- *  
- *   - Average those unscaled source values together, weighted by the area
- *     overlap with the destination pixel.  Average R, G, B separately.
- *
- *   - Take this average value and convert to a valid pixel value if
- *     necessary (e.g. rounding, shifting), and then insert it into the
- *     destination framebuffer as the pixel value.
- *
- *   - On to the next destination pixel...
- *
- * ========================================================================
- *
- * For expanding, e.g. -scale 1.1 (which we don't think people will do
- * very often... or at least so we hope, the framebuffer can become huge)
- * the situation is reversed and the destination pixel is smaller than a
- * "graph paper" unit square (source pixel).  Some destination pixels
- * will be completely within a single unscaled source pixel.
- *
- * What we do here is a simple 4 point interpolation scheme:
- * 
- * Let P00 be the source pixel closest to the destination pixel but with
- * x and y values less than or equal to those of the destination pixel.
- * (for simplicity, think of the upper left corner of a pixel defining the
- * x,y location of the pixel, the center would work just as well).  So it
- * is the source pixel immediately to the upper left of the destination
- * pixel.  Let P10 be the source pixel one to the right of P00.  Let P01
- * be one down from P00.  And let P11 be one down and one to the right
- * of P00.  They form a 2x2 square we will interpolate inside of.
- * 
- * Let V00, V10, V01, and V11 be the color values of those 4 source
- * pixels.  Let dx be the displacement along x the destination pixel is
- * from P00.  Note: 0 <= dx < 1 by definition of P00.  Similarly let
- * dy be the displacement along y.  The weighted average for the
- * interpolation is:
- * 
- * 	V_ave = V00 * (1 - dx) * (1 - dy)
- * 	      + V10 *      dx  * (1 - dy)
- * 	      + V01 * (1 - dx) *      dy
- * 	      + V11 *      dx  *      dy
- * 
- * Note that the weights (1-dx)*(1-dy) + dx*(1-dy) + (1-dx)*dy + dx*dy
- * automatically add up to 1.  It is also nice that all the weights are
- * positive (unsigned char stays unsigned char).  The above formula can
- * be motivated by doing two 1D interpolations along x:
- * 
- * 	VA = V00 * (1 - dx) + V10 * dx
- * 	VB = V01 * (1 - dx) + V11 * dx
- * 
- * and then interpolating VA and VB along y:
- * 
- * 	V_ave = VA * (1 - dy) + VB * dy
- * 
- *                      VA 
- *           v   |<-dx->|
- *           -- V00 ------ V10
- *           dy  |          |  
- *           --  |      o...|...    "o" denotes the position of the desired
- *           ^   |      .   |  .    destination pixel relative to the P00
- *               |      .   |  .    source pixel.
- *              V10 ----.- V11 .
- *                      ........
- *                      |  
- *                      VB 
- *
- * 
- * Of course R, G, B averages are done separately as in the shrinking
- * case.  This gives reasonable results, and the implementation for
- * shrinking can simply be used with different choices for weights for
- * the loop over the 4 pixels.

-# tkx11vnc v0.2
-# This is a simple frontend to x11vnc.  It uses the remote control
-# and query features (-remote/-query aka -R/-Q) to interact with it. 
-# It is just a quick-n-dirty hack (it parses -help output, etc), but
-# it could be of use playing with or learning about the (way too) many
-# parameters x11vnc has.
-# 
-# It can be used to interact with a running x11vnc (see the x11vnc
-# -gui option), or to set the parameters and then start up x11vnc.  
-# 
-
-#
-# Below is a simple picture of how the gui should be laid out and how
-# the menus should be organized.  Most menu items correspond to remote
-# control commands. A trailing ":" after the item name means it is a string
-# to be set rather than a boolean that can be toggled (e.g. the entry
-# box must be used).
-#
-# Some tweak options may be set in the prefix "=" string.
-#	A means it is an "Action" (not a true variable)
-#	R means it is an action only valid in remote mode.
-#	S means it is an action only valid in startup mode.
-#	Q means it is an action worth querying after running.
-#	P means the string can be +/- appended/deleted (string may not
-#         be the same after the remote command)
-#	G means gui internal item
-#	F means can be set via file browse
-#	D means for simple gui
-#	-C:val1,... means it will be a checkbox (radio button)
-#	   the "-" means no other options follow
-#	0 means to skip the item.
-#	-- means add a separator
-#
-#       The =GAL ... =GAL LOFF stuff is to provide submenus.

-proc set_internal_help {} {

-
-	# set some internal item help here:
-	set helptext(start) "
-Launch x11vnc with the settings you have prescribed in the gui.
-The x11vnc process is started in an xterm window so you can see the
-output, kill it, etc.
-
-By viewing this help item, the command built so far will be displayed
-in the gui text area.  Have a look.  If you Press start it will be shown
-as well and you will be asked to confirm running it.
-
-If you want to use a saved profile \"rc file\" you can do \"Misc -> rc\" and
-select the file and simply start x11vnc using the rc file.  Alternatively,
-you could first use the \"Actions -> load-settings\" action to load in
-an \"rc file\" and then press \"Actions -> start\" to start up x11vnc
-based on those values.
-"
-	set helptext(stop) "
-The \"Actions -> stop\" action sends a signal to the running x11vnc
-server indicating it should shutdown all connections and exit.
-
-The GUI stays running in case you want to start a new x11vnc or attach
-to another one.  Use \"Actions -> Quit\" if you then want to have the
-gui exit. Use \"Actions -> stop+quit\" to have both exit at once.
-"
-
-	set helptext(show-start-cmd) "
-Displays in the text area what the x11vnc start command (i.e. the command
-run by \"Actions -> start\") looks like for the current values of the
-settings.  This can be done even in the attached state.  Intended for
-debugging the gui.  The help item for \"Actions -> start\" gives the
-same info.
-
-If you want to load in a saved profile \"rc file\" use \"Misc -> rc\"
-and select the file.  \"Actions -> load-settings\" does a similar thing
-with an rc-file, but reading the file and setting the gui variables to
-its values.
-"
-
-	set helptext(debug_gui) "
-Set debug_gui to get more output printed in the text area.
-"
-
-	set helptext(detach) "
-No longer be associated with the x11vnc server.  Switch to the
-non-connected state.  The x11vnc server keeps running: it does not exit.
-
-You can either later reattach to it \"Actions -> attach\", or start
-up a new x11vnc \"Actions -> start\", or exit \"Actions -> Quit\".
-"
-
-	set helptext(attach) "
-Attach to a running x11vnc server, if possible.  Switches to connected
-state if successful.  Usually the channel used to attach is via the X
-display (VNC_CONNECT rootwin property) being polled by the x11vnc server.
-To change or set the X display to use do \"Displays -> display\".
-
-Sometimes the \"-connect /path/to/filename\" is used as the communcation
-channel.  The running x11vnc has to know that \"/path/to/filename\"
-is the communication channel (i.e. it is using the same -connect option).
-"
-
-	set helptext(ping) "
-Check if x11vnc still responds to \"ping\" remote command.
-"
-
-	set helptext(update-all) "
-Query the x11vnc server for the current values of all variables.
-Populate the values into the gui's database.
-
-Normally the gui will refresh this info every time it interacts with
-the x11vnc server (including after a few minutes of inactivity), so one
-doesn't need to use this action very often (unless something else is
-changing the state of the x11vnc server, or new clients have connected,
-etc).
-"
-
-	set helptext(clear-all) "
-Forget any variable settings either entered in by you or set at the
-default.  Basically sets everything to 0 or the string (unset).
-
-This action is only available in \"startup\" mode, not when connected
-to a running x11vnc server (in that case the variable settings reflect
-the state of the running x11vnc).  To detach from a running x11vnc
-server use \"Actions -> detach\"; to completely stop the x11vnc server
-use \"Actions -> stop\".
-"
-
-	set helptext(defaults-all) "
-Reset all variable settings to the default values.  Basically sets
-everything to the default queries \"x11vnc -QD var\" retrieved at startup.
-
-This action is only available in \"startup\" mode, not when connected
-to a running x11vnc server (in that case the variable settings reflect
-the state of the running x11vnc).  To detach from a running x11vnc
-server use \"Actions -> detach\"; to completely stop the x11vnc server
-use \"Actions -> stop\".
-"
-
-	set helptext(load-settings) "
-Read in the \"rc file\" you prescribe in the dialog and then set the
-variables to those in the rc-file.  Any variables not mentioned in the
-rc-file are set to their default value.
-
-You could then do \"Actions -> start\" to start x11vnc with these
-parameters.  Or you could make some further changes to variables
-using the gui before starting x11vnc.
-
-This action is only available in \"startup\" mode, not when connected
-to a running x11vnc server (in that case the variable settings reflect
-the state of the running x11vnc).  To detach from a running x11vnc
-server use \"Actions -> detach\"; to completely stop the x11vnc server
-use \"Actions -> stop\".
-"
-
-	set helptext(save-settings) "
-Construct a ~/.x11vncrc file based on the current settings and
-offer to save it in a file (default ~/.x11vncrc).  If saved in a
-file other than the default, you can access the profile by using
-the \"-rc <filename>\" option when starting x11vnc.
-
-If an rc file entry begins with \"#d\" that means the current
-setting is at the Default value and so you probably want to leave
-it commented out with the \"#\" character.
-
-If an rc file entry begins with \"#?\" that means we think
-you probably do not really want to force the value to this setting.
-
-In either case, feel free to uncomment the line and/or change any
-of the parameter values in the file. 
-"
-
-	set helptext(all-settings) "
-Displays the gui's database of all of the x11vnc server's current
-settings.  Use \"Actions -> update-all\"  or \"Control+R\" to
-refresh this list if it ever gets out of sync.
-"
-
-	set helptext(remote-cmd) "
-Run a remote command (-R) or query (-Q) directly.  Only a few
-remote commands are not on a menu, but for those few you can
-run the command directly this way.  Just enter the command into
-the Entry box when prompted.  Use the prefix \"Q:\" to indicate
-a -Q query.  Examples: \"zero:20,20,100,100\", \"Q:ext_xfixes\"  
-"
-
-	set helptext(stop+quit) "
-Send the stop command to the x11vnc server, then terminate the tkx11vnc gui.
-"
-
-	set helptext(show-logfile) "
-View the current contents of the logfile (if it exists and is accessible
-by the gui process).
-"
-
-	set helptext(tail-logfile) "
-Run the tail(1) command with -f option on the logfile in an xterm.
-(if it exists and is accessible by the gui process).
-"
-
-	set helptext(Quit) "
-Terminate the tkx11vnc gui.  Any x11vnc server will be left running.
-"
-
-	set helptext(current) "
-Shows a menu of currently connected VNC clients on the x11vnc server.
-
-Allows you to find more information about them, change their input
-permissions, or disconnect them.
-
-Note that the File transfer permission only applies to UltraVNC
-file transfer, not TightVNC file transfer.
-
-You will be prompted to confirm any disconnections.
-"
-
-	set helptext(client) "
-After selecting a VNC client from the \"Clients -> current\" menu,
-you will be presented with a dialog that shows the information
-about the VNC client.
-
-You can choose to disconnect the client by clicking on the 
-\"Disconnect\" checkbox and pressing \"OK\".  There will be a
-confirmation dialog to doublecheck.
-
-Alternatively, you can fine tune the VNC client's input permissions
-by selecting any of the Keystrokes, Mouse-Motion, Button-Click,
-Clipboard-Input, or Files checkboxes and pressing \"OK\".  This is like
-the \"-input\" option but on a per-client basis.
-
-To not change any aspects of the VNC client press \"Cancel\".
-"
-
-	set helptext(solid_color) "
-Set the -solid color value.
-"
-
-	set helptext(xrandr_mode) "
-Set the -xrandr mode value.
-"
-

-Set the -unixpw usernames list value.

-
-	set helptext(Tray) "
-The tray/icon mode (started with \"x11vnc -gui tray ...\", etc.) presents
-a small icon that indicates the status of the running x11vnc server.
-
-Depending on your environment, this icon may be embedded in a system
-tray or applet dock, or simply be a standalone window.  \"-gui tray\"
-will attempt to embed the icon in the system tray, while \"-gui icon\"
-is for a standalone window.  Use \"-gui tray=setpass\" (or icon=setpass)
-to be prompted to set the session password at startup.
-
-When the icon has a light background, that means no VNC viewers are
-currently connected to the VNC display.
-
-When the icon has a dark background (i.e. reverse-video), that means at
-least one VNC viewer is connected to the VNC display.
-
-Moving the mouse pointer over the icon will popup a \"status balloon\"
-indicating the VNC display name and the names and info of any connected VNC
-viewers.  Press the middle mouse button if the balloon does not appear.
-
-Clicking the left or right mouse button on the icon displays a menu
-of actions:
-
-    Properties      - Brings up the Properties dialog to set some basic
-                      parameters.  The full tkx11vnc GUI may be accessed
-                      via the \"Advanced ...\" button.  Press \"Help\"
-                      in the Properties dialog for more info.
-    
-    Help            - Displays this help text.

-
-                      Pressing \"OK\" will initiate the reverse
-                      connection.  Use a blank hostname to skip it.
-    
-    Disconnect      - Shows a popup menu of connected clients.  Click on
-                      one to disconnect it, or click on \"All Clients\"
-                      disconnect all clients.
-
-    Window View     - Switch between the \"full\" gui (also known as
-                      \"Advanced\"), \"icon\" mode (small icon window with
-                      popups), or \"tray\" mode (small icon embedded in the
-                      system tray).  This is a shortcut for the action:
-                      \"Properties -> Advanced -> Misc -> WindowView\".
-    
-    Stop x11vnc     - Directs the x11vnc server to disconnect all vncviewers
-                      and then exit.  The tray/icon GUI then exits as well.
-
-    Logfile         - Show the logfile if x11vnc is being run with one.
-
-    Custom          - If you have a \$HOME/.x11vnc.gui file each uncommented
-                      line in it becomes an additional menu item for this
-                      menu.  The remote control command is run directly
-                      via \"x11vnc -R <command>\", or if prefixed with 
-                      \"action:\" runs a gui internal action, or if \"sep\"
-                      adds a separator.  Set X11VNC_CUSTOM_GUI to use
-                      a different filename.  Example file contents:

-                             action:Quit
-
-Termination:
-
-If the x11vnc server stops for any reason, the tray/icon gui will exit.
-
-If you delete the tray/icon (e.g. X out button), that is the same
-as the \"Stop x11vnc\" action in the menu. (This will disconnect any
-VNC viewer you are currently using to access the display since the
-x11vnc server is terminated).
-
-To terminate the tray/icon gui window but not the x11vnc server press
-Control-C on the tray/icon window.  You can also do this (and much
-more) via Properties -> Advanced -> Actions -> Quit

-The Properties dialog allows you to set some basic parameters of a
-running x11vnc server.  After modifying them press \"OK\" or \"Apply\"
-to apply the changes, or press \"Cancel\" to skip applying them.
-
- Accept Connections:
-
-   Toggles whether VNC viewers are allowed to connect or not.  It corresponds
-   to the \"-R unlock\" and \"-R lock\" remote-control commands.
-
- Ask for Confirmation:
-
-   Toggles whether a popup menu will be presented at the X display when
-   a new VNC viewer attempts to connect.  The person sitting at the X
-   display can choose to accept or reject the connection or accept the
-   connection in ViewOnly mode.  It corresponds to the \"-R accept:popup\"
-   and \"-R accept:\" remote-control commands.
-   
- All Clients ViewOnly:
-
-   Toggles whether the entire VNC desktop is view only.  All clients
-   will only be able to watch when this is set (regardless of how they
-   logged in).  It corresponds to the \"-R viewonly\" and \"-R noviewonly\"
-   remote-control commands.
-   
- Shared:
-
-   Toggles whether multiple simultaneous viewer connections are allowed
-   or not.  It corresponds to the \"-R shared\" and \"-R noshared\"
-   remote-control commands.
-
- Advertise Service (Zeroconf):
-
-   Toggles whether this VNC server should advertize itself via Zeroconf
-   (also called Bonjour, mDNS, and avahi).  Then VNC viewers can then find
-   this service on the local network.  It corresponds to the \"-R zeroconf\"
-   and \"-R nozeroconf\" remote-control commands.
-
- Serve Java Viewer Applet:
-
-   Toggles whether this VNC server should serve up a Java VNC Viewer
-   applet via HTTP on http://hostname:5800/ (or port 5800+n for VNC
-   port 5900+n).  A java enabled Web Browser can then connect to the
-   desktopby VNC.  If SSL is active then the HTTPS URL https://hostname:5900/
-   (etc.) will work as well.  This requires the x11vnc java viewer jar file
-   (shared/x11vnc/classes) to be installed.  It corresponds to the
-   \"-R http\" and \"-R nohttp\" remote commands.
-
- Solid Background Color:
-
-   To improve VNC performance, if this option is set, then x11vnc will try
-   to make the desktop background a solid color (which compresses extremely
-   well compared to photo images, etc.)  It corresponds to the \"-R solid\"
-   and \"-R nosolid\" remote commands.
-
- Password:
-
-   Lets you set the session password viewers may use to gain full access
-   to the display.  This will only work if x11vnc was started with the
-   -gui icon or -gui tray mode.
-   
- ViewOnly Password:
-
-   Lets you set the session password viewers may use to gain view only
-   access to the display.  This will only work if x11vnc was started with
-   the -gui icon or -gui tray mode.
-
-
- NOTE: These \"session\" passwords only last for the current x11vnc
- session (they are not remembered, see the -storepasswd, -passwdfile,
- and -rfbauth x11vnc options for using stored passwords).
-
- If you set \"Password\" to the empty string that makes the \"ViewOnly
- Password\" empty as well and removes the need for any password to log in.
-
- If you set \"ViewOnly Password\" to the empty string that just removes
- the ViewOnly log in aspect: \"Password\" is still required to log in.
-
- - The \"Help\" button shows this help text.
-   
- - The \"Advanced ...\" button replaces the Properties dialog with the full
-   tkx11vnc GUI.  All dynamic settings can be modified in the full GUI.

-==========================================================================
-
-Don't Lock Yourself Out:
-
-   If you are sitting at the physical X display you cannot get into too
-   much trouble setting the Properties dialog values.
-
-   However IF you are using a VNC Viewer to REMOTELY access the X display
-   some items in the Properties dialog can lock you out of further access:
-
-      \"Accept Connections\"  if you disable this remotely, and
-      accidentally disconnect your VNC viewer then you will not be
-      able to reconnect.
-   
-      \"Ask for Confirmation\"  if you enable this only someone
-      sitting at the X display can confirm any new VNC connections.
-      Furthermore, any current VNC viewers will be blocked while
-      waiting for the confirmation (times out in 120 sec by default). 
-   
-      \"All Clients ViewOnly\"  if you enable this remotely, well
-      you can no longer provide input to disable it.
-   
-   If you do lock yourself out you could log in remotely and start up
-   a second x11vnc and connect to that one to try to fix things in the
-   first one.
-
-   Note that if there are two or more x11vnc's on the same display the
-   use of the GUI may be ill-behaved.  Terminate the second x11vnc as
-   soon as you have fixed the setting in the first one.  Use of a remote
-   control command, e.g. \"x11vnc -R noviewonly\" or \"x11vnc -R unlock\"
-   is a good way to avoid this problem.
-"
-
-	set helptext(all) $helpall
-
-	set helptext(Misc-Tuning:) "
-x11vnc has what seems like hundreds of tuning parameters!  In this
-sub-menu we place some lesser used ones.  Most likely you'll want to
-leave them at their default values, but you can try them out quickly
-with the gui to see if they improve things.
-"
-
-	set helptext(Passwords:) "
-The items in this sub-menu pertain to setting passwords.  Note that x11vnc
-has two types of password files: RealVNC-style ones (you can create them
-with x11vnc -storepasswd or other VNC utility program) you use these
-via -rfbauth; and plain-text file passwords you use via -passwdfile.
-
-Normally passwords cannot be changed by remote-control (e.g. the gui),
-but for the case of the \"Icon\" and \"Tray\" modes this constraint has
-been relaxed.
-
-In neither the RealVNC-style nor the plain-text file cases should the
-password files be readable by users you do not want to access the VNC
-server.  Contrary to popular belief, the  RealVNC-style passwords are
-not encrypted, merely obscured.
-
-x11vnc has the even less secure -passwd and -viewpasswd supplied on
-the command line.  Be careful with these since they could be read by
-users with something like the ps(1) command.  On some operating systems
-x11vnc tries to quickly overwrite them on the command line but it doesn't
-work everywhere.
-
-Regarding ViewOnly passwords (where a VNC client using that password
-can only watch the screen, not interact with it), this is not available
-with -rfbauth, but only with -passwdfile, -passwd, and -viewpasswd.
-"
-
-	set helptext(SSL:) "
-In this sub-menu we provide the options related to SSL encrpytion
-and authentication.
-
-There is a built-in mode (-ssl) using the OpenSSL library, and a 2nd
-using the external stunnel program (-stunnel, that needs to be installed
-on the system).  Either may require or benefit from having PEM certificate
-files specified.
-
-"
-
-	set helptext(Misc-Perms:) "
-In this sub-menu we provide some lesser used permission options.
-
-Regarding -alwaysshared, -nevershared, and -dontdisconnect, you probably
-should never use them and just use x11vnc's -shared and -forever options
-instead (these give basically the same functionality and if you mixed
-them too much unexpected things may happen).
-"
-#'
-
-	set helptext(AlphaBlending:) "
-In this sub-menu we provide some tweak parameters for cursors (little
-icon at the mouse pointer) that have transparency (i.e. an Alpha channel
-in addition to Red, Green, and Blue RGB channels).  For these cursors,
-some of the graphics underneath the cursor is allowed to be blended in:
-e.g. a drop-shadow (a terrible effect IMNSHO).
-
-AlphaBlending for x11vnc is only available when the XFIXES X extension is
-present (since otherwise it cannot see the cursors at all and so applies
-heuristics to show some fake cursors).  AlphaBlending is only a problem
-with x11vnc when the cursors are not opaque.
-
-Opaque cursors (e.g. bitmap or simply colored cursor) are rendered
-correctly by x11vnc.  Only when there is transparency does x11vnc have
-to make some approximation to transform the cursor to be opaque (the
-VNC protocol does not provide for an alpha channel in cursors, only RGB).
-
-The items in this sub-menu let you tweak x11vnc's approximation scheme
-for cursors with transparency.  Hopefully you won't have to use them.
-Certain cursor \"themes\" may require adjustment however.
-"
-#'
-	set helptext(OverlayVisuals:) "
-In this sub-menu are some options that involve fixing color problems
-for \"Overlay\" or \"Multi-Depth\" visuals.  This problem is rare
-since overlay and multi-depth visual video hardware is rare. 
-Some Sun, SGI, and HP machines are known to have them.
-
-The short answer is if you have a multi-depth visual display (e.g.  8 and
-24 bits), and you see messed up colors in x11vnc try the \"-overlay\"
-option on Solaris or IRIX.
-
-A brief Background on pixels, color, and visuals:
-
-   Pixels (picture elements) are kept in video memory as a certain number
-   of bits-per-pixel (bpp).  Most common are 8bpp, 16bpp, and 32bpp.
-   Less common are 24bpp, 4bpp, and 1bpp (monochrome).
-
-   How pixel values (i.e. values of the bits) are rendered into colors on
-   the screen can be done via different \"Recipes\".  These different
-   recipes are referred to as \"visuals\".  E.g. for 8bpp there is
-   a PseudoColor visual that maintains a mapping (that can be changed
-   dynamically) of the pixel values (256 possible ones) into RGB values.
-   Other 8bpp visuals, e.g. StaticGrey and TrueColor have fixed, regular
-   mappings and so provide less variation in kinds of colors.
-
-   A visual's \"depth\" is how many of the pixels are used in the
-   actual recipe.  This may sound wasteful (i.e. not using some of the
-   bits), but for 32bpp (4 billion colors) that is too much and nearly
-   always only 24 for them are used.  The most common Visual seems to
-   be depth 24 TrueColor at 32bpp.  This provides 16 million colors
-   which is more than the number of pixels on most screens (1280x1024 =
-   1.3 million pixels).  Another sometimes used visual that ignores some
-   bits is depth 15 TrueColor at 16bpp.
-
-OK, now, finally, to the Overlay Visuals.  Some hardware (or software
-emulations) allow different depth visuals to be used on the display
-at the same time.  The pixels of windows using different depth visuals
-may overlap.
-
-The most common seems to be both 8 and 24 depth visuals on a 32bpp setup.
-24 of the pixels can be used for one visual and the remaining 8 for the
-other.  This is sometimes referred to as \"8+24\" mode.  Furthermore,
-a speedup is achieved because writing graphics data to, say, the 8bit
-visual does not destroy the image data in the 24bit visual.  Evidently
-popup menus can be done very quickly this way: they use the 8bit visual
-and when the popup goes away the graphics data in the 24bit visual is
-immediately reexposed without having the application redraw it.
-
-Also, some legacy applications can only use 8bpp visuals.  But in these
-days of high color graphics and web browsers one would like the rest
-of the desktop to use depth 24 visuals.  They often work on the multi
-depth visuals.
-
-How does this effect x11vnc?  x11vnc nearly always polls the root window
-(container of all other windows).  The root window will be one depth,
-e.g. 8 or 24.  Any windows using the *other* depth will appear to have
-messed up colors (or just be black or some other solid color) when viewed
-via x11vnc.
-
-How to fix?  Solaris and IRIX provide an API to extract the full snapshot
-of the display with all the colors correct.  It comes to x11vnc as depth
-24 TrueColor.  To enable this use the \"-overlay\" option.  Performance
-may be slower, but if the colors are correct that is a big improvement.
-"
-
-	set helptext(8-Bit-Color:) "
-Some older displays (e.g. with limited Video RAM) use 8 bits-per-pixel
-color.  This allows for only 256 different colors on the screen at the
-same time.  This sometimes leads to problems with viewing these 8bpp
-displays via x11vnc.  This sub-menu has some options that correspond to
-workarounds for this case.  If you can configure the machine to use 16bpp
-it may be worth it to avoid the color problems (e.g. color flashing
-as the 8bit colormap is switched).
-"
-	set helptext(SubWindow:) "
-This sub-menu has a couple options regarding having x11vnc poll a 
-single window, not the entire display.  This way just the window
-is shared.
-
-Note if the application pops up multiple windows they are not tracked
-and shared.  So this is not application sharing.  The application has to
-be very simple (e.g. a simple terminal or the image window on a webcam)
-for this mode to be usable.
-"
-	set helptext(ResizeRotate:) "
-This sub-menu has some options regarding screens that support the X
-Resize, Reflection, and Rotation Extension (RANDR), and one expects screen
-resizing, reflection, or rotation to take place during the x11vnc session.
-This is pretty rare, but x11vnc seems to handle it reasonably well using
-this X extension.
-
-This mode is on by default in -id mode to try to track the changing
-size of the SubWindow.  It is not on by default for full-screen mode
-because of the extra overhead, etc.
-"
-
-	set helptext(WireFrame:) "
-This sub-menu has some options for the x11vnc wireframing speedup scheme.
-
-For x11vnc, Wireframing means to watch for toplevel windows being Opaquely
-Moved or Resized.  When x11vnc detects this, it stops polling the screen
-and simply shows a \"wireframe\" outline of the window as it is being
-moved or resized.  This avoids \"screen polling thrashing\" when the
-screen is changing so rapidly during this period.  For various reasons
-this is usually much faster then letting the window manager do its
-own wireframing (you are encouraged to do Opaque moves and resizes
-when using x11vnc!)
-
-Also, once a moved window is released in its new position, x11vnc uses
-the VNC CopyRect encoding to very efficiently update the VNC viewers
-(each just copies the image data locally).
-
-This sort of scheme was used much in the 1990's on local displays because
-video hardware was slow at the time.  x11vnc tries to use this same trick
-as a speedup for its activities (the network is much slower than video
-hardware writes, and the video hardware reads that x11vnc uses to poll
-the screen are still slow today).
-"
-#'"
-
-	set helptext(Safe:) "
-In this sub-menu are some options for making x11vnc operations
-more, or less, safe.  E.g. disable the running of external commands, etc.
-
-You can also turn off the Remote control channel (NOTE that doing that
-will disable the GUI from being able to communicate with x11vnc).
-"
-
-	set helptext(X-ext:) "
-In this sub-menu are a few rarely used options regarding some X extensions
-used by x11vnc.
-"
-	set helptext(Clipping:) "
-In this sub-menu are some options regarding clipping or blacking out
-portions of the Screen.  E.g. under XINERAMA when the multiple monitors
-are not the same size.
-
-"
-	set helptext(Misc-Screen:) "
-In this sub-menu are some little used options modifying aspects of
-the screen source.
-"
-
-	set helptext(Settings:) "
-In this sub-menu are some options for saving and loading option settings.
-The default file to store settings in is ~/.x11vncrc, but you can save
-different \"profiles\" in other files for later use.
-
-"
-	set helptext(Java-applet:) "
-In this sub-menu are some options for running the built-in HTTP server
-that delivers the TightVNC Java VNC Viewer applet (VncViewer.jar) to
-clients.  The viewer runs in their Web browser.
-
-The default port listened on is 5800, so the URL is typically:
-
-	http://hostname:5800/
-
-but this can be altered by -httpport, etc.
-"
-
-	set helptext(Chat:) "
-In this sub-menu are some options for enabling a local chat window
-and starting or stopping the current chat.  This is the UltraVNC 
-Text Chat support in x11vnc.
-"
-
-	set helptext(ScrollCopyRect:) "
-This sub-menu has some options for the x11vnc Scroll detection and
-CopyRect speedup scheme.
-
-For this mode, x11vnc \"spies\" on communication between the X server and
-applications using the RECORD extension.  It looks for various patterns
-to detect a scrolled window.  This only works for some applications,
-fortunately some important ones.
-
-Once the scroll is detected it uses the VNC CopyRect encoding for a
-big speedup.  Screen polling is also sped up for this scheme.
-
-There are many tweakable parameters for this mode and they are described
-in the sub-menu items.
-"
-
-	set helptext(XDAMAGE:) "
-The DAMAGE X extension allows the X server to send signals to x11vnc
-telling it which regions of the screen have been changed.  This improves
-x11vnc's performance markedly.  The DAMAGE extension must be available
-on the display for this to work.
-
-Unfortunately DAMAGE cannot be trusted completely for the changed regions,
-because often the reported changed region is much larger than the actual
-changed regions.  Nevertheless, x11vnc uses the DAMAGE information very
-effectively as hints to improve its performance.
-
-The items in the sub-menu allow tweaking x11vnc's DAMAGE algorithm.
-"
-
-	set helptext(Ncache:) "
-A simple client-side (viewer) caching scheme is enabled with the
-\"-ncache n\" option.  It simply uses \"n\" framebuffer sized areas
-below the actual display for caching window pixel data.  
-
-Drawbacks are it uses a lot of RAM (roughly n times more), and the
-pixels cache area is visible in the viewers.
-
-The items in the sub-menu allow tweaking x11vnc's -ncache algorithm.
-"
-
-	set helptext(SharedMemory:) "
-This sub-menu provides some options regarding SYSV shared memory usage
-(shm) by x11vnc.  Usually you want shm turned on because the x11vnc
-process is nearly always running on the same machine the X server process
-is running on.  SharedMemory gives a performance speedup.  However, if you
-need to modify this scenario for special usage these options allow you to.
-"
-
-	set helptext(Misc-Debug:) "
-This sub-menu contains a lot of debugging parameters usually used
-for debugging x11vnc itself.  This is unlike the -debug_pointer and
--debug_keyboard options that are useful in learning information, quirks,
-etc. about your local display and environment.
-"
-
-	set helptext(Selection:) "
-This sub-menu contains some options centering around the Selection
-(also referred to as the Clipboard, Cutbuffers, etc).  x11vnc will try
-to exchange the selections between the VNC viewers and the X server.
-You can adjust that behavior with these options.
-"
-
-	set helptext(WindowView) "
-Set the Window View Mode for the gui.  There are three modes:
-
-  - full:  Presents the full gui (Actions, Clients, etc, buttons,
-           and the Text area and Set/Entry box).
-
-  - icon:  Presents a small icon instead of the full gui.  Moving
-           the mouse over it shows the VNC display name and any
-           connected clients.  Clicking on the icon pops up a menu
-           of actions to perform.  Among them is \"Properties\" that
-           allows setting more parameters.  Clicking on \"Advanced\"
-           in \"Properties\" brings up the full gui.
-
-  - tray:  Attempt to embed the small icon in the system tray.  If
-           this fails it will resort to icon mode where the small icon
-           is a standalone window.
-
-Note that in \"full\" mode if you delete the full gui window the gui
-terminates (but the x11vnc server keeps running).  However under \"icon\"
-or \"tray\" mode if you bring up the full gui window via \"Properties ->
-Advanced\" and then delete it the gui does NOT terminate.
-
-Also note that by default in \"icon\" mode if you delete the icon
-window both the gui *and* the x11vnc server terminate.

-tkx11vnc is a simple frontend to x11vnc.  Nothing fancy, it merely
-provides an interface to each of the many x11vnc command line options and
-remote control commands.  See \"Help -> all\" for much info about x11vnc.
-
-For a simplier gui, run x11vnc in \"tray\" or \"icon\" mode such as
-\"-gui tray\", \"-gui icon\", or \"-gui tray=setpass\".  In that
-mode the full gui is only available under \"Advanced ...\".
-
-Also, \"-gui ez\" will show fewer menu items (toggle via Misc -> simple_gui)
-
-All menu items have a (?) button one can click on to get more information
-about the option or command.
-
-There are two states tkx11vnc can be in:
-
-	1) Available to control a running x11vnc process.
-
-	2) Getting ready to start a x11vnc process.
-
-Most people will just use state 1).
-
-In state 1) the Menu items available in the menus are those that
-correspond to the x11vnc \"remote control\" commands.  See the -remote
-entry under \"Help -> all\" for a complete list.  Also available is
-the \"Actions -> stop\" item to shut down the running x11vnc server,
-thereby changing to state 2).  There are other actions available too.
-
-In state 2) the Menu items available in the menus (\"Actions\", \"Clients\",
-etc.) are those that correspond to command line options used in starting
-an x11vnc process, and the \"Actions -> start\" item executes
-x11vnc thereby changing to state 1).  To see what x11vnc startup command
-you have built so far, look at the (?) help for  \"Actions -> start\"
-and it will show you what the command looks like.
-
-There is much overlap between the menu items available in state 1)
-and state 2), but it is worth keeping in mind it is not 100%.
-For example, you cannot set passwords or password files in state 1).
-(update: simple password setting is now allowed in \"tray\" or \"icon\" mode).
-
-
-Also note that there may be *two* separate X displays involved, not just
-one:  1) the X display x11vnc will be polling (and making available to
-VNC viewers), and 2) the X display this GUI is intended to display on.
-
-For example, one might use ssh to access the remote machine where the
-GUI would display on :11 and x11vnc would poll display :0.  By default
-the gui will display on the value in the DISPLAY env. variable followed
-by the value from the -display option.  To override this, use something
-like: \"-gui otherhost:0\", etc.
-
-
-GUI components: 
---- ----------
-
-1) At the top of the gui is a info text label where information will
-   be posted, e.g. when traversing menu items text indicating how to get
-   help on the item and its current value will be displayed.
-
-2) Below the info label is the area where the menu buttons, \"Actions\",
-   \"Clients\", etc., are presented.  If a menu item has a checkbox,
-   it corresponds to a boolean on/off variable.  Otherwise it is
-   either a string variable, or an action not associated with a
-   variable (for the most part).
-
-3) Below the menu button area is a label indicating the current x11vnc
-   X display being polled and the corresponding VNC display name.  Both
-   will be \"(*none*)\" when there is no connection established.
-
-4) Below the x11 and vnc displays label is a text area there scrolling
-   information about actions being taken and commands being run is displayed.
-   To scroll click in the area and use PageUp/PageDown or the arrow keys.
-
-5) At the bottom is an entry area.  When one selects a menu item that
-   requires supplying a string value, the label will be set to the
-   parameter name and one types in the new value.  Then one presses the
-   \"OK\" button or presses \"Enter\" to set the value.  Or you can press
-   \"Cancel\" or \"Escape\" to avoid changing the variable.
-
-   Many variables are boolean toggles (for example, \"Permissions ->
-   viewonly\") or Radio button selections.  Selecting these menu items
-   will NOT activate the entry area but rather toggle the variable
-   immediately.
-
-
-CASCADES BUG: There is a bug not yet worked around for the cascade menus
-where the (?) help button gets in the way.  To get the mouse over to
-the cascade menu click and release mouse to activate the cascade, then
-you can click on its items.  Dragging with a mouse button held down will
-not work (sorry!).
-
-
-Key Bindings:
-
-	In the Text Area: Control-/ selects all of the text.
-	Anywhere: Control-d invokes \"Actions -> detach\"
-	Anywhere: Control-a invokes \"Actions -> attach\"
-	Anywhere: Control-p invokes \"Actions -> ping\"
-	Anywhere: Control-u and Control-r invoke \"Actions -> update-all\"

-Misc:
-
-Since x11vnc has so many settings and to avoid further confusion,
-the libvncserver options:
-
-	-alwaysshared
-	-nevershared
-	-dontdisconnect
-
-are not available for changing in a running x11vnc (even though it
-is feasible).  These options overlap with the x11vnc options -shared
-and -forever which are hopefully enough for most usage.  They may be
-specified for x11vnc startup if desired.

-#
-# For booleans, the line will end with comment \"default: on\" or
-# \"default: off\" indicating the default setting.  (Note: often
-# \"-nofoobar\" corresponds to option \"-foobar\" and the former is
-# \"the default\", e.g. -norepeat).
-#
-# For string or numerical options, the value \"\" in a line below

-"# It is just a quick-n-dirty hack (it parses -help output, etc), but\n"
-"# it could be of use playing with or learning about the (way too) many\n"
-"# parameters x11vnc has.\n"
-"# \n"
-"# It can be used to interact with a running x11vnc (see the x11vnc\n"

-"# Below is a simple picture of how the gui should be laid out and how\n"
-"# the menus should be organized.  Most menu items correspond to remote\n"

-"# to be set rather than a boolean that can be toggled (e.g. the entry\n"
-"# box must be used).\n"
-"#\n"
-"# Some tweak options may be set in the prefix \"=\" string.\n"
-"#	A means it is an \"Action\" (not a true variable)\n"
-"#	R means it is an action only valid in remote mode.\n"

-"#	F means can be set via file browse\n"

-"   always only 24 for them are used.  The most common Visual seems to\n"
-"   be depth 24 TrueColor at 32bpp.  This provides 16 million colors\n"
-"   which is more than the number of pixels on most screens (1280x1024 =\n"
-"   1.3 million pixels).  Another sometimes used visual that ignores some\n"
-"   bits is depth 15 TrueColor at 16bpp.\n"
-"\n"
-"OK, now, finally, to the Overlay Visuals.  Some hardware (or software\n"
-"emulations) allow different depth visuals to be used on the display\n"
-"at the same time.  The pixels of windows using different depth visuals\n"
-"may overlap.\n"
-"\n"
-"The most common seems to be both 8 and 24 depth visuals on a 32bpp setup.\n"
-"24 of the pixels can be used for one visual and the remaining 8 for the\n"
-"other.  This is sometimes referred to as \\\"8+24\\\" mode.  Furthermore,\n"
-"a speedup is achieved because writing graphics data to, say, the 8bit\n"
-"visual does not destroy the image data in the 24bit visual.  Evidently\n"
-"popup menus can be done very quickly this way: they use the 8bit visual\n"
-"and when the popup goes away the graphics data in the 24bit visual is\n"
-"immediately reexposed without having the application redraw it.\n"
-"\n"
-"Also, some legacy applications can only use 8bpp visuals.  But in these\n"
-"days of high color graphics and web browsers one would like the rest\n"
-"of the desktop to use depth 24 visuals.  They often work on the multi\n"
-"depth visuals.\n"
-"\n"
-"How does this effect x11vnc?  x11vnc nearly always polls the root window\n"
-"(container of all other windows).  The root window will be one depth,\n"
-"e.g. 8 or 24.  Any windows using the *other* depth will appear to have\n"
-"messed up colors (or just be black or some other solid color) when viewed\n"
-"via x11vnc.\n"
-"\n"
-"How to fix?  Solaris and IRIX provide an API to extract the full snapshot\n"
-"of the display with all the colors correct.  It comes to x11vnc as depth\n"
-"24 TrueColor.  To enable this use the \\\"-overlay\\\" option.  Performance\n"
-"may be slower, but if the colors are correct that is a big improvement.\n"

-"displays via x11vnc.  This sub-menu has some options that correspond to\n"
-"workarounds for this case.  If you can configure the machine to use 16bpp\n"

-"Moved or Resized.  When x11vnc detects this, it stops polling the screen\n"
-"and simply shows a \\\"wireframe\\\" outline of the window as it is being\n"
-"moved or resized.  This avoids \\\"screen polling thrashing\\\" when the\n"
-"screen is changing so rapidly during this period.  For various reasons\n"
-"this is usually much faster then letting the window manager do its\n"
-"own wireframing (you are encouraged to do Opaque moves and resizes\n"
-"when using x11vnc!)\n"
-"\n"
-"Also, once a moved window is released in its new position, x11vnc uses\n"
-"the VNC CopyRect encoding to very efficiently update the VNC viewers\n"
-"(each just copies the image data locally).\n"
-"\n"
-"This sort of scheme was used much in the 1990's on local displays because\n"
-"video hardware was slow at the time.  x11vnc tries to use this same trick\n"
-"as a speedup for its activities (the network is much slower than video\n"

-.TH X11VNC "1" "December 2010" "x11vnc " "User Commands"
-.SH NAME
-x11vnc - allow VNC connections to real X11 displays
-         version: 0.9.13, lastmod: 2010-12-27
-.SH SYNOPSIS
-.B x11vnc
-[OPTION]...
-.SH DESCRIPTION
-.PP
-Typical usage is:
-.IP
-Run this command in a shell on the remote machine "far-host"
-with X session you wish to view:
-.IP
-x11vnc -display :0
-.IP
-Then run this in another window on the machine you are sitting at:
-.IP
-vncviewer far-host:0
-.PP
-Once x11vnc establishes connections with the X11 server and starts listening
-as a VNC server it will print out a string: PORT=XXXX where XXXX is typically
-5900 (the default VNC server port).  One would next run something like
-this on the local machine: "vncviewer hostname:N" where "hostname" is
-the name of the machine running x11vnc and N is XXXX - 5900, i.e. usually
-"vncviewer hostname:0".
-.PP
-By default x11vnc will not allow the screen to be shared and it will exit
-as soon as the client disconnects.  See \fB-shared\fR and \fB-forever\fR below to override
-these protections.  See the FAQ for details how to tunnel the VNC connection
-through an encrypted channel such as 
-.IR ssh (1).
-In brief:
-.IP
-ssh \fB-t\fR \fB-L\fR 5900:localhost:5900 far-host 'x11vnc \fB-localhost\fR \fB-display\fR :0'
-.PP
-% vncviewer -encodings 'copyrect tight zrle hextile' localhost:0
-.PP
-Also, use of a VNC password (-rfbauth or \fB-passwdfile)\fR is strongly recommended.
-.PP
-For additional info see: http://www.karlrunge.com/x11vnc/
-and  http://www.karlrunge.com/x11vnc/faq.html
-.PP
-Config file support: if the file $HOME/.x11vncrc exists then each line in
-it is treated as a single command line option.  Disable with \fB-norc.\fR  For
-each option name, the leading character "-" is not required.  E.g. a line
-that is either "forever" or "\fB-forever\fR" may be used and are equivalent.
-Likewise "wait 100" or "\fB-wait\fR \fI100\fR" are acceptable and equivalent lines.
-The "#" character comments out to the end of the line in the usual way
-(backslash it for a literal).  Leading and trailing whitespace is trimmed off.
-Lines may be continued with a "\\" as the last character of a line (it
-becomes a space character).
-.PP
-.SH OPTIONS
-
-.PP
-\fB-display\fR \fIdisp\fR
-.IP
-X11 server display to connect to, usually :0.  The X
-server process must be running on same machine and
-support MIT-SHM.  Equivalent to setting the DISPLAY
-environment variable to \fIdisp\fR.
-.IP
-See the description below of the "\fB-display\fR \fIWAIT:...\fR"
-extensions, where alias "\fB-find\fR" will find the user's
-display automatically, and "\fB-create\fR" will create a
-Xvfb session if no session is found.
-.PP
-\fB-auth\fR \fIfile\fR
-.IP
-Set the X authority file to be \fIfile\fR, equivalent to
-setting the XAUTHORITY environment variable to \fIfile\fR
-before startup.  Same as \fB-xauth\fR file.  See 
-.IR Xsecurity (7)
-,
-.IR xauth (1)
-man pages for more info.
-.IP
-Use '-auth guess' to have x11vnc use its \fB-findauth\fR
-mechanism (described below) to try to guess the
-XAUTHORITY filename and use it.
-.IP
-XDM/GDM/KDM: if you are running x11vnc as root and want
-to find the XAUTHORITY before anyone has logged into an
-X session yet, use: x11vnc \fB-env\fR FD_XDM=1 \fB-auth\fR guess ...
-(This will also find the XAUTHORITY if a user is already
-logged into the X session.)  When running as root,
-FD_XDM=1 will be tried if the initial \fB-auth\fR guess fails.
-.PP
-\fB-N\fR
-.IP
-If the X display is :N, try to set the VNC display to
-also be :N This just sets the \fB-rfbport\fR option to 5900+N
-The program will exit immediately if that port is not
-available. The \fB-N\fR option only works with normal \fB-display\fR
-usage, e.g. :0 or :8, \fB-N\fR is ignored in the \fB-display\fR
-WAIT:..., \fB-create,\fR \fB-find,\fR \fB-svc,\fR \fB-redirect,\fR etc modes.
-.PP
-\fB-autoport\fR \fIn\fR
-.IP
-Automatically probe for a free VNC port starting at n.
-The default is to start probing at 5900.  Use this to
-stay away from other VNC servers near 5900.
-.PP
-\fB-rfbport\fR \fIstr\fR
-.IP
-The VNC port to listen on (a LibVNCServer option), e.g.
-5900, 5901, etc.  If specified as "\fB-rfbport\fR \fIPROMPT\fR"
-then the x11vnc \fB-gui\fR is used to prompt the user to
-enter the port number.
-.PP
-\fB-6\fR
-.IP
-IPv6 listening support.  In addition to IPv4, the
-IPv6 address is listened on for incoming connections.
-The same port number as IPv4 is used.
-.IP
-NOTE:  This x11vnc binary was compiled to have the
-"-6" IPv6 listening mode ENABLED by default (CPPFLAGS
-\fB-DX11VNC_LISTEN6=1).\fR  So to disable IPv6 listening mode
-you MUST supply the "\fB-no6\fR" option (see below.)
-.IP
-The "-6" mode works for both normal connections and
-\fB-ssl\fR encrypted ones.  Nearly everything is supported
-for the IPv6 case, but there are a few exceptions.
-See \fB-stunnel\fR for its IPv6 support.
-.IP
-Currently, for absolutely everything to work correctly
-the machine may need to have some IPv4 support, at the
-least for the loopback interface.  However, for nearly
-all usage modes no IPv4 support is required. See \fB-nopiv4.\fR
-.IP
-If you have trouble compiling or running in IPv6 mode,
-set \fB-DX11VNC_IPV6=0\fR in CPPFLAGS when configuring to
-disable IPv6 support.
-.PP
-\fB-no6\fR
-.IP
-Disable IPv6 listening support (only useful if the
-"-6" mode is compiled in to be the default; see the
-X11VNC_LISTEN6 description above under "-6".)
-.PP
-\fB-noipv6\fR
-.IP
-Do not try to use IPv6 for any listening or connecting
-sockets.  This includes both the listening service
-port(s) and outgoing connections from \fB-connect,\fR
-\fB-connect_or_exit,\fR or \fB-proxy.\fR  Use this if you are having
-problems due to IPv6.
-.PP
-\fB-noipv4\fR
-.IP
-Do not try to use IPv4 for any listening or connecting
-sockets.  This is mainly for exploring the behavior of
-x11vnc on an IPv6-only system, but may have other uses.
-.PP
-\fB-reopen\fR
-.IP
-If the X server connection is disconnected, try to
-reopen the X display (up to one time.)  This is of use
-for display managers like GDM (KillInitClients option)
-that kill x11vnc just after the user logs into the
-X session.  Note: the reopened state may be unstable.
-Set X11VNC_REOPEN_DISPLAY=n to reopen n times and
-set X11VNC_REOPEN_SLEEP_MAX to the number of seconds,
-default 10, to keep trying to reopen the display (once
-per second.)
-.IP
-Update: as of 0.9.9, x11vnc tries to automatically avoid
-being killed by the display manager by delaying creating
-windows or using XFIXES.  So you shouldn't need to use
-KillInitClients=false as long as you log in quickly
-enough (within 45 seconds of connecting.)  You can
-disable this by setting X11VNC_AVOID_WINDOWS=never.
-You can also set it to the number of seconds to delay.
-.PP
-\fB-reflect\fR \fIhost:N\fR
-.IP
-Instead of connecting to and polling an X display,
-connect to the remote VNC server host:N and be a
-reflector/repeater for it.  This is useful for trying
-to manage the case of many simultaneous VNC viewers
-(e.g. classroom broadcasting) where, e.g. you put
-a repeater on each network switch, etc, to improve
-performance by distributing the load and network
-traffic.  Implies \fB-shared\fR (use \fB-noshared\fR as a later
-option to disable). See the discussion below under
-\fB-rawfb\fR vnc:host:N for more details.
-.PP
-\fB-id\fR \fIwindowid\fR
-.IP
-Show the X window corresponding to \fIwindowid\fR not
-the entire display.  New windows like popup menus,
-transient toplevels, etc, may not be seen or may be
-clipped.  Disabling SaveUnders or BackingStore in the
-X server may help show them.  x11vnc may crash if the
-window is initially partially obscured, changes size,
-is iconified, etc.  Some steps are taken to avoid this
-and the \fB-xrandr\fR mechanism is used to track resizes.  Use
-.IR xwininfo (1)
-to get the window id, or use "\fB-id\fR \fIpick\fR"
-to have x11vnc run 
-.IR xwininfo (1)
-for you and extract
-the id.  The \fB-id\fR option is useful for exporting very
-simple applications (e.g. the current view on a webcam).
-.PP
-\fB-sid\fR \fIwindowid\fR
-.IP
-As \fB-id,\fR but instead of using the window directly it
-shifts a root view to it: this shows SaveUnders menus,
-etc, although they will be clipped if they extend beyond
-the window.
-.PP
-\fB-appshare\fR
-.IP
-Simple application sharing based on the \fB-id/-sid\fR
-mechanism.  Every new toplevel window that the
-application creates induces a new viewer window via
-a reverse connection.  The \fB-id/-sid\fR and \fB-connect\fR
-options are required.  Run 'x11vnc \fB-appshare\fR \fB-help'\fR
-for more info.
-.PP
-\fB-clip\fR \fIWxH+X+Y\fR
-.IP
-Only show the sub-region of the full display that
-corresponds to the rectangle geometry with size WxH and
-offset +X+Y.  The VNC display has size WxH (i.e. smaller
-than the full display).  This also works for \fB-id/-sid\fR
-mode where the offset is relative to the upper left
-corner of the selected window.  An example use of this
-option would be to split a large (e.g. Xinerama) display
-into two parts to be accessed via separate viewers by
-running a separate x11vnc on each part.
-.IP
-Use '-clip xinerama0' to clip to the first xinerama
-sub-screen (if xinerama is active).  xinerama1 for the
-2nd sub-screen, etc.  This way you don't need to figure
-out the WxH+X+Y of the desired xinerama sub-screen.
-screens are sorted in increasing distance from the
-(0,0) origin (I.e. not the Xserver's order).
-.PP
-\fB-flashcmap\fR
-.IP
-In 8bpp indexed color, let the installed colormap flash
-as the pointer moves from window to window (slow).
-Also try the \fB-8to24\fR option to avoid flash altogether.
-.PP
-\fB-shiftcmap\fR \fIn\fR
-.IP
-Rare problem, but some 8bpp displays use less than 256
-colorcells (e.g. 16-color grayscale, perhaps the other
-bits are used for double buffering) *and* also need to
-shift the pixels values away from 0, .., ncells.  \fIn\fR
-indicates the shift to be applied to the pixel values.
-To see the pixel values set DEBUG_CMAP=1 to print out
-a colormap histogram.  Example: \fB-shiftcmap\fR 240
-.PP
-\fB-notruecolor\fR
-.IP
-For 8bpp displays, force indexed color (i.e. a colormap)
-even if it looks like 8bpp TrueColor (rare problem).
-.PP
-\fB-advertise_truecolor\fR
-.IP
-If the X11 display is indexed color, lie to clients
-when they first connect by telling them it is truecolor.
-To workaround RealVNC: inPF has colourMap but not 8bpp
-Use '-advertise_truecolor reset' to reset client fb too.
-.PP
-\fB-visual\fR \fIn\fR
-.IP
-This option probably does not do what you think.
-It simply *forces* the visual used for the framebuffer;
-this may be a bad thing... (e.g. messes up colors or
-cause a crash). It is useful for testing and for some
-workarounds.  n may be a decimal number, or 0x hex.
-Run 
-.IR xdpyinfo (1)
-for the values.  One may also use
-"TrueColor", etc. see <X11/X.h> for a list.  If the
-string ends in ":m" then for better or for worse
-the visual depth is forced to be m.  You may want to
-use \fB-noshm\fR when using this option (so XGetImage may
-automatically translate the pixel data).
-.PP
-\fB-overlay\fR
-.IP
-Handle multiple depth visuals on one screen, e.g. 8+24
-and 24+8 overlay visuals (the 32 bits per pixel are
-packed with 8 for PseudoColor and 24 for TrueColor).
-.IP
-Currently \fB-overlay\fR only works on Solaris via
-.IR XReadScreen (3X11)
-and IRIX using 
-.IR XReadDisplay (3).
-On Solaris there is a problem with image "bleeding"
-around transient popup menus (but not for the menu
-itself): a workaround is to disable SaveUnders
-by passing the "\fB-su\fR" argument to Xsun (in
-/etc/dt/config/Xservers).
-.IP
-Use \fB-overlay\fR as a workaround for situations like these:
-Some legacy applications require the default visual to
-be 8bpp (8+24), or they will use 8bpp PseudoColor even
-when the default visual is depth 24 TrueColor (24+8).
-In these cases colors in some windows will be incorrect
-in x11vnc unless \fB-overlay\fR is used.  Another use of
-\fB-overlay\fR is to enable showing the exact mouse cursor
-shape (details below).
-.IP
-Under \fB-overlay,\fR performance will be somewhat slower
-due to the extra image transformations required.
-For optimal performance do not use \fB-overlay,\fR but rather
-configure the X server so that the default visual is
-depth 24 TrueColor and try to have all apps use that
-visual (e.g. some apps have \fB-use24\fR or \fB-visual\fR options).
-.PP
-\fB-overlay_nocursor\fR
-.IP
-Sets \fB-overlay,\fR but does not try to draw the exact mouse
-cursor shape using the overlay mechanism.
-.PP
-\fB-8to24\fR \fI[opts]\fR
-.IP
-Try this option if \fB-overlay\fR is not supported on your
-OS, and you have a legacy 8bpp app that you want to
-view on a multi-depth display with default depth 24
-(and is 32 bpp) OR have a default depth 8 display with
-depth 24 overlay windows for some apps.  This option
-may not work on all X servers and hardware (tested
-on XFree86/Xorg mga driver and Xsun).  The "opts"
-string is not required and is described below.
-.IP
-This mode enables a hack where x11vnc monitors windows
-within 3 levels from the root window.  If it finds
-any that are 8bpp it extracts the indexed color
-pixel values using XGetImage() and then applies a
-transformation using the colormap(s) to create TrueColor
-RGB values that it in turn inserts into bits 1-24 of
-the framebuffer.  This creates a depth 24 "view"
-of the display that is then exported via VNC.
-.IP
-Conversely, for default depth 8 displays, the depth
-24 regions are read by XGetImage() and everything is
-transformed and inserted into a depth 24 TrueColor
-framebuffer.
-.IP
-Note that even if there are *no* depth 24 visuals or
-windows (i.e. pure 8bpp), this mode is potentially
-an improvement over \fB-flashcmap\fR because it avoids the
-flashing and shows each window in the correct color.
-.IP
-This method works OK, but may still have bugs and it
-does hog resources.  If there are multiple 8bpp windows
-using different colormaps, one may have to iconify all
-but one for the colors to be correct.
-.IP
-There may be painting errors for clipping and switching
-between windows of depths 8 and 24.  Heuristics are
-applied to try to minimize the painting errors.  One can
-also press 3 Alt_L's in a row to refresh the screen
-if the error does not repair itself.  Also the option
-\fB-fixscreen\fR 8=3.0 or \fB-fixscreen\fR V=3.0 may be used to
-periodically refresh the screen at the cost of bandwidth
-(every 3 sec for this example).
-.IP
-The [opts] string can contain the following settings.
-Multiple settings are separated by commas.
-.IP
-For for some X servers with default depth 24 a
-speedup may be achieved via the option "nogetimage".
-This enables a scheme were XGetImage() is not used
-to retrieve the 8bpp data.  Instead, it assumes that
-the 8bpp data is in bits 25-32 of the 32bit X pixels.
-There is no requirement that the X server should put
-the data there for our poll requests, but some do and
-so the extra steps to retrieve it can be skipped.
-Tested with mga driver with XFree86/Xorg.  For the
-default depth 8 case this option is ignored.
-.IP
-To adjust how often XGetImage() is used to poll the
-non-default visual regions for changes, use the option
-"poll=t" where "t" is a floating point time.
-(default: 0.05)
-.IP
-Setting the option "level2" will limit the search
-for non-default visual windows to two levels from the
-root window.  Do this on slow machines where you know
-the window manager only imposes one extra window between
-the app window and the root window.
-.IP
-Also for very slow machines use "cachewin=t"
-where t is a floating point amount of time to cache
-XGetWindowAttributes results.  E.g. cachewin=5.0.
-This may lead to the windows being unnoticed for this
-amount of time when deiconifying, painting errors, etc.
-.IP
-While testing on a very old SS20 these options gave
-tolerable response: \fB-8to24\fR poll=0.2,cachewin=5.0. For
-this machine \fB-overlay\fR is supported and gives better
-response.
-.IP
-Debugging for this mode can be enabled by setting
-"dbg=1", "dbg=2", or "dbg=3".
-.PP
-\fB-24to32\fR
-.IP
-Very rare problem: if the framebuffer (X display
-or \fB-rawfb)\fR is 24bpp instead of the usual 32bpp, then
-dynamically transform the pixels to 32bpp.  This will be
-slower, but can be used to work around problems where
-VNC viewers cannot handle 24bpp (e.g. "main: setPF:
-not 8, 16 or 32 bpp?").  See the FAQ for more info.
-.IP
-In the case of \fB-rawfb\fR mode, the pixels are directly
-modified by inserting a 0 byte to pad them out to 32bpp.
-For X displays, a kludge is done that is equivalent to
-"\fB-noshm\fR \fI\fB-visual\fR TrueColor:32\fR".  (If better performance
-is needed for the latter, feel free to ask).
-.PP
-\fB-scale\fR \fIfraction\fR
-.IP
-Scale the framebuffer by factor \fIfraction\fR.  Values
-less than 1 shrink the fb, larger ones expand it. Note:
-the image may not be sharp and response may be slower.
-If \fIfraction\fR contains a decimal point "." it
-is taken as a floating point number, alternatively
-the notation "m/n" may be used to denote fractions
-exactly, e.g. \fB-scale\fR 2/3
-.IP
-To scale asymmetrically in the horizontal and vertical
-directions, specify a WxH geometry to stretch to:
-e.g. '-scale 1024x768', or also '-scale 0.9x0.75'
-.IP
-Scaling Options: can be added after \fIfraction\fR via
-":", to supply multiple ":" options use commas.
-If you just want a quick, rough scaling without
-blending, append ":nb" to \fIfraction\fR (e.g. \fB-scale\fR
-1/3:nb).  No blending is the default for 8bpp indexed
-color, to force blending for this case use ":fb".
-.IP
-To disable \fB-scrollcopyrect\fR and \fB-wirecopyrect\fR under
-\fB-scale\fR use ":nocr".  If you need to to enable them use
-":cr" or specify them explicitly on the command line.
-If a slow link is detected, ":nocr" may be applied
-automatically.  Default: :cr
-.IP
-More esoteric options: for compatibility with vncviewers
-the scaled width is adjusted to be a multiple of 4:
-to disable this use ":n4".  ":in" use interpolation
-scheme even when shrinking, ":pad" pad scaled width
-and height to be multiples of scaling denominator
-(e.g. 3 for 2/3).
-.PP
-\fB-geometry\fR \fIWxH\fR
-.IP
-Same as \fB-scale\fR WxH
-.PP
-\fB-scale_cursor\fR \fIfrac\fR
-.IP
-By default if \fB-scale\fR is supplied the cursor shape is
-scaled by the same factor.  Depending on your usage,
-you may want to scale the cursor independently of the
-screen or not at all.  If you specify \fB-scale_cursor\fR
-the cursor will be scaled by that factor.  When using
-\fB-scale\fR mode to keep the cursor at its "natural" size
-use "\fB-scale_cursor\fR \fI1\fR".  Most of the ":" scaling
-options apply here as well.
-.PP
-\fB-viewonly\fR
-.IP
-All VNC clients can only watch (default off).
-.PP
-\fB-shared\fR
-.IP
-VNC display is shared, i.e. more than one viewer can
-connect at the same time (default off).
-.PP
-\fB-once\fR
-.IP
-Exit after the first successfully connected viewer
-disconnects, opposite of \fB-forever.\fR This is the Default.
-.PP
-\fB-forever\fR
-.IP
-Keep listening for more connections rather than exiting
-as soon as the first client(s) disconnect. Same as \fB-many\fR
-.IP
-To get the standard non-shared VNC behavior where when
-a new VNC client connects the existing VNC client is
-dropped use:  \fB-nevershared\fR \fB-forever\fR   This method can
-also be used to guard against hung TCP connections that
-do not go away.
-.PP
-\fB-loop\fR
-.IP
-Create an outer loop restarting the x11vnc process
-whenever it terminates.  \fB-bg\fR and \fB-inetd\fR are ignored
-in this mode (however see \fB-loopbg\fR below).
-.IP
-Useful for continuing even if the X server terminates
-and restarts (at that moment the process will need
-permission to reconnect to the new X server of course).
-.IP

-Note: if you are not redirecting stderr to a log file
-(via shell 2> or \fB-o\fR option) you MUST also specify the \fB-q\fR

-Use commas for a list of host's and host:port's.
-E.g. \fB-connect\fR host1,host2 or host1:0,host2:5678.
-Note that to reverse connect to multiple hosts at the

-Note that unlike most vnc servers, x11vnc will require a

-(provided password auth has been enabled, \fB-rfbauth,\fR etc)
-If you do not want to require a password for reverse
-connections set X11VNC_REVERSE_CONNECTION_NO_AUTH=1 in

-Repeater mode: Some services provide an intermediate
-"vnc repeater": http://www.uvnc.com/addons/repeater.html
-(and also http://koti.mbnet.fi/jtko/ for linux port)
-that acts as a proxy/gateway.  Modes like these require
-an initial string to be sent for the reverse connection
-before the VNC protocol is started.  Here are the ways
-to do this:
-.IP
-\fB-connect\fR pre=some_string+host:port
-\fB-connect\fR pre128=some_string+host:port
-\fB-connect\fR repeater=ID:1234+host:port
-\fB-connect\fR repeater=23.45.67.89::5501+host:port
-.IP
-SSVNC notation is also supported:
-.IP
-\fB-connect\fR repeater://host:port+ID:1234
-.IP
-As with normal \fB-connect\fR usage, if the repeater port is
-not supplied 5500 is assumed.
-.IP
-The basic idea is between the special tag, e.g. "pre="
-and "+" is the pre-string to be sent.  Note that in
-this case host:port is the repeater server, NOT the
-vnc viewer.  Somehow the pre-string tells the repeater
-server how to find the vnc viewer and connect you to it.
-.IP
-In the case pre=some_string+host:port, "some_string"
-is simply sent. In the case preNNN=some_string+host:port
-"some_string" is sent in a null padded buffer of
-length NNN.  repeater= is the same as pre250=, this is
-the ultravnc repeater buffer size.
-.IP
-Strings like "\\n" and "\\r", etc. are expanded to
-newline and carriage return.  "\\c" is expanded to
-"," since the connect string is comma separated.
-.IP
-See also the \fB-proxy\fR option below for additional ways
-to plumb reverse connections.
-.IP
-Reverse SSL: using \fB-connect\fR in \fB-ssl\fR mode makes x11vnc
-act as an SSL client (initiates SSL connection) rather
-than an SSL server.  The idea is x11vnc might be
-connecting to stunnel on the viewer side with the
-viewer in listening mode.  If you do not want this
-behavior, use \fB-env\fR X11VNC_DISABLE_SSL_CLIENT_MODE=1.
-With this the viewer side can act as the SSL client
-as it normally does for forward connections.
-.IP
-Reverse SSL Repeater mode:  This will work, but note
-that if the VNC Client does any sort of a 'Fetch Cert'
-action before connecting, then the Repeater will
-likely drop the connection and both sides will need
-to restart.  Consider the use of \fB-connect_or_exit\fR
-and \fB-loop300,2\fR to have x11vnc reconnect once to the
-repeater after the fetch.  You will probably also want
-to supply \fB-sslonly\fR to avoid x11vnc thinking the delay
-in response means the connection is VeNCrypt.  The env
-var X11VNC_DISABLE_SSL_CLIENT_MODE=1 discussed above
-may also be useful (i.e. the viewer can do a forward
-connection as it normally does.)
-.IP
-IPv6: as of x11vnc 0.9.10 the \fB-connect\fR option should
-connect to IPv6 hosts properly.  If there are problems
-you can disable IPv6 by setting \fB-DX11VNC_IPV6=0\fR
-in CPPFLAGS when configuring.  If there problems
-connecting to IPv6 hosts consider a relay like the
-included inet6to4 script or the \fB-proxy\fR option.
-.PP
-\fB-connect_or_exit\fR \fIstr\fR
-.IP
-As with \fB-connect,\fR except if none of the reverse
-connections succeed, then x11vnc shuts down immediately
-.IP
-An easier to type alias for this option is '-coe'
-.IP
-By the way, if you do not want x11vnc to listen on
-ANY interface use \fB-rfbport\fR 0  which is handy for the
-\fB-connect_or_exit\fR mode.
-.PP
-\fB-proxy\fR \fIstring\fR
-.IP
-Use proxy in string (e.g. host:port) as a proxy for
-making reverse connections (-connect or \fB-connect_or_exit\fR
-options).
-.IP
-Web proxies are supported, but note by default most of
-them only support destination connections to ports 443
-or 563, so this might not be very useful (the viewer
-would need to listen on that port or the router would
-have to do a port redirection).
-.IP
-A web proxy may be specified by either "host:port"
-or "http://host:port" (the port is required even if
-it is the common choices 80 or 8080)
-.IP
-SOCKS4, SOCKS4a, and SOCKS5 are also supported.
-SOCKS proxies normally do not have restrictions on the
-destination port number.
-.IP
-Use a format like this: socks://host:port or
-socks5://host:port.  Note that ssh \fB-D\fR does not support
-SOCKS4a, so use socks5://.  For socks:// SOCKS4 is used
-on a numerical IP and "localhost", otherwise SOCKS4a
-is used (and so the proxy tries to do the DNS lookup).
-.IP
-An experimental mode is "\fB-proxy\fR \fIhttp://host:port/...\fR"
-Note the "/" after the port that distinguishes it from
-a normal web proxy.  The port must be supplied even if
-it is the default 80.  For this mode a GET is done to
-the supplied URL with the string host=H&port=P appended.
-H and P will be the \fB-connect\fR reverse connect host
-and port.  Use the string "__END__" to disable the
-appending.  The basic idea here is that maybe some cgi
-script provides the actual viewer hookup and tunnelling.
-How to actually achieve this within cgi, php, etc. is
-not clear...  A custom web server or apache module
-would be straight-forward.
-.IP
-Another experimental mode is "\fB-proxy\fR \fIssh://user@host\fR"
-in which case a SSH tunnel is used for the proxying.
-"user@" is not needed unless your unix username is
-different on "host".  For a non-standard SSH port
-use ssh://user@host:port.  If proxies are chained (see
-next paragraph) then the ssh one must be the first one.
-If ssh-agent is not active, then the ssh password needs
-to be entered in the terminal where x11vnc is running.
-Examples:
-.IP
-\fB-connect\fR localhost:0 \fB-proxy\fR ssh://me@friends-pc:2222
-.IP
-\fB-connect\fR snoopy:0 \fB-proxy\fR ssh://ssh.company.com
-.IP
-Multiple proxies may be chained together in case one
-needs to ricochet off of a number of hosts to finally
-reach the VNC viewer.  Up to 3 may be chained, separate
-them by commas in the order they are to be connected to.
-E.g.:  http://host1:port1,socks5://host2:port2 or three
-like:  first,second,third
-.IP
-IPv6: as of x11vnc 0.9.10 the \fB-proxy\fR option should
-connect to IPv6 hosts properly.  If there are problems
-you can disable IPv6 by setting \fB-DX11VNC_IPV6=0\fR

-.IP
-A rare case, but for non-localhost \fB-listen\fR usage, if
-you use the remote control mechanism (-R) to change
-the \fB-listen\fR interface you may need to manually adjust
-the \fB-allow\fR list (and vice versa) to avoid situations

-\fB-unixsock\fR \fIstr\fR
-.IP
-Listen on the unix socket (AF_UNIX) 'str'
-for connections.  This mode is for either local

-edit to libvnserver/rfbserver.c: comment out lines 310
-and 311, 'close(sock)' and 'return NULL' in rfbserver.c
-after the setsockopt() call.) Note that to disable all
-tcp listening ports specify '-rfbport 0' and should be
-useful with this mode.  Example:
-mkdir ~/s; chmod 700 ~/s;
-x11vnc \fB-unixsock\fR ~/s/mysock \fB-rfbport\fR 0 ...

-is for Clipboard input, and "F" is for File transfer
-(ultravnc only).  Their presence in the string enables
-that type of input.  E.g. "\fB-input\fR \fIM\fR" means normal

-If the filename is prefixed with "read:" it will

-so that the latest passwords will be used.
-.IP
-If \fIfilename\fR is prefixed with "cmd:" then the

-when a client authenticates.  If the command exits with
-0 the client is accepted, otherwise it is rejected.
-The environment variables are set as in \fB-accept.\fR
-.IP
-The standard input to the custom command will be a
-decimal digit "len" followed by a newline. "len"
-specifies the challenge size and is usually 16 (the

-.IP
-The "custom:" scheme can be useful to implement

-to immediately switch to user nobody where the su'ing
-will proceed normally.
-.IP
-Another source of potential problems are PAM modules
-that prompt for extra info, e.g. password aging modules.
-These logins will fail as well even when the correct
-password is supplied.
-.IP
-**IMPORTANT**: to prevent the Unix password being sent
-in *clear text* over the network, one of two schemes
-will be enforced: 1) the \fB-ssl\fR builtin SSL mode, or 2)
-require both \fB-localhost\fR and \fB-stunnel\fR be enabled.
-.IP
-Method 1) ensures the traffic is encrypted between
-viewer and server.  A PEM file will be required, see the
-discussion under \fB-ssl\fR below (under some circumstances
-a temporary one can be automatically generated).
-.IP
-Method 2) requires the viewer connection to appear
-to come from the same machine x11vnc is running on
-(e.g. from a ssh \fB-L\fR port redirection).  And that the
-\fB-stunnel\fR SSL mode be used for encryption over the
-network. (see the description of \fB-stunnel\fR below).
-.IP
-Note: as a convenience, if you 
-.IR ssh (1)
-in and start
-x11vnc it will check if the environment variable
-SSH_CONNECTION is set and appears reasonable.  If it
-does, then the \fB-ssl\fR or \fB-stunnel\fR requirement will be
-dropped since it is assumed you are using ssh for the
-encrypted tunnelling.  \fB-localhost\fR is still enforced.
-Use \fB-ssl\fR or \fB-stunnel\fR to force SSL usage even if
-SSH_CONNECTION is set.
-.IP
-To override the above restrictions you can set
-environment variables before starting x11vnc:
-.IP
-Set UNIXPW_DISABLE_SSL=1 to disable requiring either
-\fB-ssl\fR or \fB-stunnel\fR (as under SSH_CONNECTION.)  Evidently
-you will be using a different method to encrypt the
-data between the vncviewer and x11vnc: perhaps 
-.IR ssh (1)
-or an IPSEC VPN. \fB-localhost\fR is still enforced (however,
-see the next paragraph.)
-.IP
-Set UNIXPW_DISABLE_LOCALHOST=1 to disable the \fB-localhost\fR
-requirement in \fB-unixpw\fR modes.  One should never do this
-(i.e. allow the Unix passwords to be sniffed on the
-network.)  This also disables the localhost requirement
-for reverse connections (see below.)
-.IP
-Note that use of \fB-localhost\fR with 
-.IR ssh (1)
-(and no \fB-unixpw)\fR
-is roughly the same as requiring a Unix user login
-(since a Unix password or the user's public key
-authentication is used by sshd on the machine where
-x11vnc runs and only local connections from that machine
-are accepted).
-.IP
-Regarding reverse connections (e.g. \fB-R\fR connect:host
-and \fB-connect\fR host), when the \fB-localhost\fR constraint is
-in effect then reverse connections can only be used
-to connect to the same machine x11vnc is running on
-(default port 5500).  Please use a ssh or stunnel port
-redirection to the viewer machine to tunnel the reverse
-connection over an encrypted channel.
-.IP
-In \fB-inetd\fR mode the Method 1) will be enforced (not
-Method 2).  With \fB-ssl\fR in effect reverse connections
-are disabled.  If you override this via env. var, be
-sure to also use encryption from the viewer to inetd.
-Tip: you can also have your own stunnel spawn x11vnc
-in \fB-inetd\fR mode (thereby bypassing inetd).  See the FAQ
-for details.
-.IP
-The user names in the comma separated [list] may have
-per-user options after a ":", e.g. "fred:opts"
-where "opts" is a "+" separated list of
-"viewonly", "fullaccess", "input=XXXX", or
-"deny", e.g. "karl,wally:viewonly,boss:input=M".
-For "input=" it is the K,M,B,C described under \fB-input.\fR
-.IP
-If an item in the list is "*" that means those
-options apply to all users.  It ALSO implies all users
-are allowed to log in after supplying a valid password.
-Use "deny" to explicitly deny some users if you use
-"*" to set a global option.  If [list] begins with the
-"!" character then "*" is ignored for checking if
-the user is allowed, but the option values associated
-with it do apply as normal.
-.IP
-There are also some utilities for checking passwords
-if [list] starts with the "%" character.  See the
-quick_pw() function for more details.  Description:
-"%-" or "%stdin" means read one line from stdin.
-"%env" means it is in $UNIXPW env var.  A leading
-"%/" or "%." means read the first line from the
-filename that follows after the % character. % by
-itself means prompt for the username and password.
-Otherwise: %user:pass   E.g. \fB-unixpw\fR %fred:swordfish
-For the other cases user:pass is read from the indicated
-source.  If the password is correct 'Y user' is printed
-and the program exit code is 0.  If the password is
-incorrect it prints 'N user' and the exit code is 1.
-If there is some other error the exit code is 2.
-This feature enables x11vnc to be a general unix user
-password checking tool; it could be used from scripts
-or other programs.  These % password checks also apply
-to the \fB-unixpw_nis\fR and \fB-unixpw_cmd\fR options.
-.IP
-For the % password check, if the env. var. UNIXPW_CMD
-is set to a command then it is run as the user (assuming
-the password is correct.)  The output of the command is
-not printed, the program or script must manage that by
-some other means.  The exit code of x11vnc will depend
-on the exit code of the command that is run.

-.IP
-This mode requires that the encrypted passwords be

-.IP
-This is called "NIS" mode simply because in most

-NIS is not required for this mode to work (only that

-Dynamic passwords and non-unix passwords, e.g. LDAP,

-Otherwise, in xdmcp FINDCREATEDISPLAY mode the user

-of it.  If the display string begins with WAIT: then
-x11vnc waits until a VNC client connects before opening
-the X display (or \fB-rawfb\fR device).
-.IP
-This could be useful for delaying opening the display
-for certain usage modes (say if x11vnc is started at
-boot time and no X server is running or users logged
-in yet).
-.IP
-If the string is, e.g. WAIT:0.0 or WAIT:1, i.e. "WAIT"
-in front of a normal X display, then that indicated
-display is used.
-.IP
-One can also insert a geometry between colons, e.g.
-WAIT:1280x1024:... to set the size of the display the
-VNC client first attaches to since some VNC viewers
-will not automatically adjust to a new framebuffer size.
-.IP
-A more interesting case is like this:
-.IP
-WAIT:cmd=/usr/local/bin/find_display
-.IP
-in which case the command after "cmd=" is run to
-dynamically work out the DISPLAY and optionally the
-XAUTHORITY data.  The first line of the command output
-must be of the form DISPLAY=<xdisplay>.  On Linux
-if the virtual terminal is known append ",VT=n" to
-this string and the 
-.IR chvt (1)
-program will also be run.
-Any remaining output is taken as XAUTHORITY data.
-It can be either of the form XAUTHORITY=<file> or raw
-xauthority data for the display. For example;
-.IP
-xauth extract - $DISPLAY"
-.IP
-NOTE: As specified in the previous paragraph, you can
-supply your own WAIT:cmd=... program or script, BUT
-there are two very useful *BUILT-IN* ones: FINDDISPLAY
-(alias \fB-find\fR above) and FINDCREATEDISPLAY (alias \fB-create\fR
-above.)  Most people use these instead of creating
-their own script.  Read the following (especially the
-BUILT-IN modes sections) to see how to configure these
-two useful builtin \fB-display\fR WAIT: modes.
-.IP
-In the case of \fB-unixpw\fR (and \fB-unixpw_nis\fR only if x11vnc
-is running as root), then the cmd= command is run
-as the user who just authenticated via the login and
-password prompt.
-.IP
-In the case of \fB-unixpw_cmd,\fR the commands will also be
-run as the logged-in user, as long as the user-supplied
-helper program supports RFB_UNIXPW_CMD_RUN (see the
-\fB-unixpw_cmd\fR option.)
-.IP
-Also in the case of \fB-unixpw,\fR the user logging in can
-place a colon at the end of her username and supply
-a few options: scale=, scale_cursor= (or sc=), solid
-(or so), id=, clear_mods (or cm), clear_keys (or
-ck), clear_all (or ca), repeat, speeds= (or sp=),
-readtimeout= (or rd=), viewonly (or vo), nodisplay=
-(or nd=), rotate= (or ro=), or noncache (or nc),
-all separated by commas if there is more than one.
-After the user logs in successfully, these options will
-be applied to the VNC screen.  For example,
-.IP
-login: fred:scale=3/4,sc=1,repeat
-Password: ...
-.IP
-login: runge:sp=modem,rd=120,solid
-.IP
-for convenience m/n implies scale= e.g. fred:3/4  If you
-type and enter your password incorrectly, to retrieve
-your long "login:" line press the Up arrow once
-(before typing anything else).
-.IP
-Most of these colon options only apply to the builtin
-FINDDISPLAY and FINDCREATEDISPLAY modes, but note
-that they are passed to the extrenal command in the
-environment as well and so could be used.
-.IP
-In the login panel, press F1 to get a list of the
-available options that you can add after the username.
-.IP
-Another option is "geom=WxH" or "geom=WxHxD" (or
-ge=). This only has an effect in FINDCREATEDISPLAY
-mode when a virtual X server such as Xvfb is going
-to be created.  It sets the width and height of
-the new display, and optionally the color depth as
-well.
-.IP
-You can also supply "gnome", "kde", "twm",
-"fvwm", "mwm", "dtwm", "wmaker", "xfce",
-"lxde", "enlightenment", "Xsession", or
-"failsafe" (same as "xterm") to have the created
-display use that mode for the user session.
-.IP
-Specify "tag=..." to set the unique FD_TAG desktop
-session tag described below.  Note: this option will
-be ignored if the FD_TAG env. var. is already set or
-if the viewer-side supplied value is not completely
-composed of alphanumeric or '_' or '-' characters.
-.IP
-User preferences file: Instead of having the user type
-in geom=WxH,... etc. every time he logs in to find
-or create his X session, if you set FD_USERPREFS to
-a string that does not contain the "/" character,
-then the user's home directory is prepended to that
-string and if the file exists its first line is read
-and appended to any options he supplied at the login:
-prompt.  For example \fB-env\fR FD_USERPREFS=.x11vnc_create
-and the user put "geom=1600x1200" in his
-~/.x11vnc_create file.
-.IP
-To disable the option setting set the environment
-variable X11VNC_NO_UNIXPW_OPTS=1 before starting x11vnc.
-To set any other options, the user can use the gui
-(x11vnc \fB-gui\fR connect) or the remote control method
-(x11vnc \fB-R\fR opt:val) during his VNC session.
-.IP
-So we see the combination of \fB-display\fR WAIT:cmd=... and
-\fB-unixpw\fR allows automatic pairing of an unix
-authenticated VNC user with his desktop.  This could
-be very useful on SunRays and also any system where
-multiple users share a given machine.  The user does
-not need to remember special ports or passwords set up
-for his desktop and VNC.
-.IP
-A nice way to use WAIT:cmd=... is out of 
-.IR inetd (8)
-(it automatically forks a new x11vnc for each user).
-You can have the x11vnc inetd spawned process run as,
-say, root or nobody.  When run as root (for either inetd
-or display manager), you can also supply the option
-"\fB-users\fR \fIunixpw=\fR" to have the x11vnc process switch to
-the user as well.  Note: there will be a 2nd SSL helper
-process that will not switch, but it is only encoding

-.IP
-An interesting option is WAIT:cmd=FINDCREATEDISPLAY
-that is like FINDDISPLAY in that is uses the same method
-to find an existing display.  However, if it does not
-find one it will try to *start* up an X server session
-for the user.  This is the only time x11vnc tries to
-actually start up an X server.
-.IP
-NOTE: The option "\fB-create\fR" is an alias for this mode.
-.IP
-It will start looking for an open display number at :20
-Override via X11VNC_CREATE_STARTING_DISPLAY_NUMBER=n
-By default 80 X displays are allowed (i.e. going to :99)
-Override via X11VNC_CREATE_MAX_DISPLAYS=n
-.IP
-For its heuristics, the create display script sets
-LC_ALL=C so that command output is uniform.  By default

-LC_ALL=C set the env. var.: X11VNC_CREATE_LC_ALL_C_OK=1
-.IP
-By default FINDCREATEDISPLAY will try Xvfb and then
-Xdummy:
-.IP
-The Xdummy wrapper is part of the x11vnc source code
-(x11vnc/misc/Xdummy)  It should be available in PATH
-and have run "Xdummy \fB-install"\fR once to create the
-shared library.  Xdummy only works on Linux.  As of
-12/2009 it no longer needs to be run as root, and the
-default is to not run as root.  In some circumstances

-cases specify FD_XDUMMY_RUN_AS_ROOT=1, this is the same
-as supplying \fB-root\fR to the Xdummy cmdline.
-.IP
-Xvfb is available on most platforms and does not
-require root.
-.IP
-An advantage of Xdummy over Xvfb is that Xdummy supports
-RANDR dynamic screen resizing.
-.IP
-When x11vnc exits (i.e. user disconnects) the X

-The FINDDISPLAY will find it directly next time.
-The user must exit the X session in the usual way for

-To troubleshoot the FINDCREATEDISPLAY mechanism,
-set the following env. var. to an output log file,

-.IP
-So this is a somewhat odd mode for x11vnc in that it
-will start up and poll virtual X servers!  This can
-be used from, say, 
-.IR inetd (8)

-More FD tricks:  FD_CUPS=port or FD_CUPS=host:port
-will set the cups printing environment.  Similarly for
-FD_ESD=port or FD_ESD=host:port for esddsp sound

-Another special mode is FINDCREATEDISPLAY-Xvnc.redirect,
-(or FINDDISPLAY-Xvnc.redirect).  In this case it will
-start up Xvnc as above if needed, but instead of
-polling it in its normal way, it simply does a socket
-redirection of the connected VNC viewer to the Xvnc.
-.IP
-So in Xvnc.redirect x11vnc does no VNC but merely
-transfers the data back and forth.  This should be
-faster then x11vnc's polling method, but not as fast
-as connecting directly to the Xvnc with the VNC Viewer.
-The idea here is to take advantage of x11vnc's display
-finding/creating scheme, SSL, and perhaps a few others.
-Most of x11vnc's options do not apply in this mode.

-They provide VNC Certificate Authority (CA) key creation

-provide a basic Public Key management framework for
-VNC-ing with x11vnc. (note that they require

-be installed on the system)
-.IP
-However, the simplest usage mode, "\fB-ssl\fR \fITMP\fR" (where
-x11vnc automatically generates its own, self-signed,
-temporary key and the VNC viewers always accept it,
-e.g. accepting via a dialog box) is probably safe enough
-for most scenarios.  CA management is not needed.
-.IP
-To protect against Man-In-The-Middle attacks the "TMP"
-mode can be improved by using "\fB-ssl\fR \fISAVE\fR" (same as
-"\fB-ssl\fR", i.e. the default) to have x11vnc create a
-longer term self-signed certificate, and then (safely)
-copy the corresponding public key cert to the desired
-client machines (care must be taken the private key part
-is not stolen; you will be prompted for a passphrase).
-.IP
-So keep in mind no CA key creation or management
-(-sslGenCA and \fB-sslGenCert)\fR is needed for either of
-the above two common usage modes.

-Next, he could create signed VNC server keys

-.IP
-x11vnc will be able to use all of these cert and

-.IP
-Only rarely will one's x11vnc \fB-ssl\fR infrastructure be so
-large that this option would be useful (since normally
-maintaining the contents of the \fB-sslverify\fR file or

-x11vnc with a Certificate Authority (see \fB-sslGenCA)\fR
-to authenticate Clients via SSL/TLS, the \fB-sslCRL\fR option
-can be useful to revoke users' certs whose private SSL
-keys were lost or stolen (e.g. laptop.)  This way a new
-CA cert+key does not need to be created and new signed
-client keys generated and distributed to all users.
-.IP
-To create a CRL file with revoked certificates the
-commands 'openssl ca \fB-revoke\fR ...' and 'openssl ca

-The type of key to be generated is the string \fItype\fR.
-It is either "server" (i.e. for use by x11vnc) or
-"client" (for a VNC viewer).  Note that typically
-only "server" is used: the VNC clients authenticate
-themselves by a non-public-key method (e.g. VNC or
-unix password).  \fItype\fR is required.
-.IP
-An arbitrary default name you want to associate with
-the key is supplied by the \fIname\fR string.  You can
-change it at the various prompts when creating the key.
-\fIname\fR is optional.
-.IP
-If name is left blank for clients keys then "nobody"
-is used.  If left blank for server keys, then the

-is the saved one referenced by "\fB-ssl\fR \fISAVE\fR" when the
-server is started)
-.IP
-If \fIname\fR begins with the string "self:" then
-a self-signed certificate is created instead of one
-signed by your CA key.
-.IP
-If \fIname\fR begins with the string "req:" then only a
-key (.key) and a certificate signing *request* (.req)
-are generated.  You can then send the .req file to
-an external CA (even a professional one, e.g. Thawte)
-and then combine the .key and the received cert into
-the .pem file with the same basename.
-.IP
-The distinction between "server" and "client" is
-simply the choice of output filenames and sub-directory.
-This makes it so the \fB-ssl\fR SAVE-name option can easily
-pick up the x11vnc PEM file this option generates.
-And similarly makes it easy for the \fB-sslverify\fR option
-to pick up your client certs.

-.IP
-Note you cannot recreate a cert with exactly the same
-distiguished name (DN) as an existing one.  To do so,
-you will need to edit the [dir]/CA/index.txt file to
-delete the line.
-.IP
-Similar to \fB-sslGenCA,\fR you will be prompted to fill
-in some information that will be recorded in the

-.IP
-Tip: if you know the fully-qualified hostname other
-people will be connecting to, you can use that as the
-CommonName "CN" to avoid some applications (e.g. web
-browsers and java plugin) complaining that it does not
-match the hostname.
-.IP
-You will also need to supply the CA private key
-passphrase to unlock the private key created from
-\fB-sslGenCA.\fR  This private key is used to sign the server
-or client certificate.
-.IP
-The "server" certs can be used by x11vnc directly by
-pointing to them via the \fB-ssl\fR [pem] option.  The default
-file will be ~/.vnc/certs/server.pem.  This one would
-be used by simply typing \fB-ssl\fR SAVE.  The pem file
-contains both the certificate and the private key.
-server.crt file contains the cert only.
-.IP
-The "client" cert + private key file will need
-to be copied and imported into the VNC viewer
-side applications (Web browser, Java plugin,
-stunnel, etc.)  Once that is done you can delete the
-"client" private key file on this machine since
-it is only needed on the VNC viewer side.  The,
-e.g. ~/.vnc/certs/clients/<name>.pem contains both
-the cert and private key.  The <name>.crt contains the
-certificate only.
-.IP
-NOTE: It is very important to know one should
-generate new keys with a passphrase.  Otherwise if an
-untrusted user steals the key file he could use it to
-masquerade as the x11vnc server (or VNC viewer client).
-You will be prompted whether to encrypt the key with
-a passphrase or not.  It is recommended that you do.
-One inconvenience to a passphrase is that it must
-be typed in EVERY time x11vnc or the client app is
-started up.
-.IP
-Examples:
-.IP
-x11vnc \fB-sslGenCert\fR server
-x11vnc \fB-ssl\fR SAVE \fB-display\fR :0 ...
-.IP
-and then on viewer using ss_vncviewer stunnel wrapper

-NOTE: It is recommended that you use SSL via the \fB-ssl\fR

-that you do not have control over.
-.IP
-Note that this mode will NOT work with the UltraVNC DSM

-to tunnelling with the symmetric cipher (an unfortunate
-choice of implementation...)
-.IP
-cipher can be one of:  arc4, aesv2, aes-cfb, blowfish,
-aes256, or 3des.  See the OpenSSL documentation for

-Here is one way to make a keyfile with that many bits:
-.IP
-dd if=/dev/random of=./my.key bs=16 count=1
-.IP
-you will need to securely share this key with the other
-side of the VNC connection (See SSVNC for examples).
-.IP
-Example:  \fB-enc\fR blowfish:./my.key
-Example:  \fB-enc\fR blowfish:pw=swordfish
-.IP
-By default 16 bytes of random salt followed by 16 bytes
-of random initialization vector are sent at the very
-beginning of the stream.  The other side must read these
-and initialize their cipher with them.  These values
-make the session key unique (without them the security
-is minimal).  Similarly, the other side must send us
-its random salt and IV with those same lengths.
-.IP
-The salt and key data are combined to create a session
-key using an md5 hash as described in 
-.IR EVP_BytesToKey (3).
-.IP
-The exact call is: EVP_BytesToKey(Cipher, EVP_md5(),
-salt, keydata, len, 1, keystr, NULL);  where salt is
-the random data as described above, and keydata is the
-shared secret key data.  keystr is the resulting session
-key.  The cipher is then seeded with keystr and uses
-the random initialization vector as its first block.
-.IP
-To modify the amount of random salt and initialization
-vector use cipher@n,m where n is the salt length and
-m the initialization vector length.  E.g.
-.IP
-\fB-enc\fR aes-cfb@8,16:./my.key
-.IP
-It is not a good idea to set either one to zero,
-although you may be forced to if the other side of the
-tunnel is not under your control.
-.IP
-To skip the salt and EVP_BytesToKey MD5 entirely (no
-hashing is done: the keydata is directly inserted into
-the cipher) specify "-1" for the salt, e.g.
-.IP
-\fB-enc\fR blowfish@-1,16:./my.key
-.IP
-The message digest can also be changed to something
-besides the default MD5.  Use cipher@md+n,m where "md"
-can be one of sha, sha1, md5, or ripe.  For example:
-.IP
-\fB-enc\fR arc4@sha+8,16:./my.key
-.IP
-The SSVNC vnc viewer project supplies a symmetric
-encryption tool named "ultravnc_dsm_helper" that can
-be used on the viewer side.  For example:
-.IP
-ssvncviewer exec='ultravnc_dsm_helper arc4 my.key 0 h:p'
-.IP
-where h:p is the hostname and port of the x11vnc server.
-ultravnc_dsm_helper may also be used standalone to
-provide a symmetric encryption tunnel for any viewer
-or server (VNC or otherwise.) The cipher (1st arg)
-is basically the same syntax as we use above.
-.IP
-Also see the 'Non-Ultra DSM' SSVNC option for the

-\fB-https\fR \fI[port]\fR
-.IP
-Use a special, separate HTTPS port (-ssl and
-\fB-stunnel\fR modes only) for HTTPS Java viewer applet
-downloading. I.e. not 5900 and not 5800 (the defaults.)
-.IP
-BACKGROUND: In \fB-ssl\fR mode, it turns out you can use the
-single VNC port (e.g. 5900) for both VNC and HTTPS
-connections. (HTTPS is used to retrieve a SSL-aware
-VncViewer.jar applet that is provided with x11vnc).
-Since both use SSL the implementation was extended to
-detect if HTTP traffic (i.e. GET) is taking place and
-handle it accordingly.  The URL would be, e.g.:
-.IP
-https://mymachine.org:5900/
-.IP
-This is convenient for firewalls, etc, because only one
-port needs to be allowed in.  However, this heuristic
-adds a few seconds delay to each connection and can be
-unreliable (especially if the user takes much time to
-ponder the Certificate dialogs in his browser, Java VM,
-or VNC Viewer applet.  That's right 3 separate "Are
-you sure you want to connect?" dialogs!)
-.IP
-END OF BACKGROUND.
-.IP
-USAGE: So use the \fB-https\fR option to provide a separate,
-more reliable HTTPS port that x11vnc will listen on.  If
-[port] is not provided (or is 0), one is autoselected.
-The URL to use is printed out at startup.

-\fB-httpsredir\fR \fI[port]\fR
-.IP
-In \fB-ssl\fR mode with the Java applet retrieved via HTTPS,
-when the HTML file containing applet parameters
-('index.vnc' or 'proxy.vnc') is sent do NOT set the
-applet PORT parameter to the actual VNC port but set it
-to "port" instead.  If "port" is not supplied, then
-the port number is guessed from the Host: HTTP header.
-.IP
-This is useful when an incoming TCP connection
-redirection is performed by a router/gateway/firewall
-from one port to an internal machine where x11vnc is
-listening on a different port. The Java applet needs to
-connect to the firewall/router port, not the VNC port
-on the internal workstation. For example, one could
-redir from mygateway.com:443 to workstation:5900.
-.IP
-This spares the user from having to type in
-https://mygateway.com/?PORT=443 into their web
-browser. Note that port 443 is the default https port;
-other ports must be explicitly indicated, for example:
-https://mygateway.com:8000/?PORT=8000.  To avoid having
-to include the PORT= in the browser URL, simply supply
-"\fB-httpsredir\fR" to x11vnc.
-.IP
-This option does not work in \fB-stunnel\fR mode.
-.IP
-More tricks: set the env var X11VNC_EXTRA_HTTPS_PARAMS
-to be extra URL parameters to use.  This way you do
-not need to specify extra PARAMS in the index.vnc file.
-E.g. x11vnc \fB-env\fR X11VNC_EXTRA_HTTPS_PARAMS='?GET=1' ...
-.IP
-If you do not want to expose the non-SSL HTTP port to

-port, e.g. 5900, open for connections) then specify the
-option \fB-env\fR X11VNC_HTTP_LISTEN_LOCALHOST=1  This way
-the connection to the LibVNCServer httpd server will

-If x11vnc is running as root (say from

-of the tcp virtual circuit.  The x11vnc process
-id will be in RFB_X11VNC_PID, a client id number in
-RFB_CLIENT_ID, and the number of other connected clients
-in RFB_CLIENT_COUNT.  RFB_MODE will be "accept".
-RFB_STATE will be PROTOCOL_VERSION, SECURITY_TYPE,
-AUTHENTICATION, INITIALISATION, NORMAL, or UNKNOWN
-indicating up to which state the client has achieved.
-RFB_LOGIN_VIEWONLY will be 0, 1, or -1 (unknown).
-RFB_USERNAME, RFB_LOGIN_TIME, and RFB_CURRENT_TIME may
-also be set.

-If \fIstring\fR is "popup" then a builtin popup window

-.IP
-In the case of "popup" and when the \fB-unixpw\fR option
-is specified, then a *second* window will be popped
-up after the user successfully logs in via his UNIX

-UNIX:username@hostname, the "UNIX:" prefix indicates
-which user the viewer logged as via \fB-unixpw.\fR  The first

-to login via unix password.
-.IP
-If \fIstring\fR is "xmessage" then an 
-.IR xmessage (1)
-invocation is used for the command.  xmessage must be
-installed on the machine for this to work.
-.IP
-Both "popup" and "xmessage" will present an option
-for accepting the client "View-Only" (the client
-can only watch).  This option will not be presented if
-\fB-viewonly\fR has been specified, in which case the entire
-display is view only.
-.IP
-If the user supplied command is prefixed with something
-like "yes:0,no:*,view:3 mycommand ..." then this
-associates the numerical command return code with
-the actions: accept, reject, and accept-view-only,
-respectively.  Use "*" instead of a number to indicate
-the default action (in case the command returns an
-unexpected value).  E.g. "no:*" is a good choice.
-.IP
-Note that x11vnc blocks while the external command
-or popup is running (other clients may see no updates
-during this period).  So a person sitting a the physical
-display is needed to respond to an popup prompt. (use
-a 2nd x11vnc if you lock yourself out).
-.IP
-More \fB-accept\fR tricks: use "popupmouse" to only allow
-mouse clicks in the builtin popup to be recognized.
-Similarly use "popupkey" to only recognize
-keystroke responses.  These are to help avoid the
-user accidentally accepting a client by typing or
-clicking. All 3 of the popup keywords can be followed

-as possible after connections to the X display are
-established try to switch to one of the users in the
-comma separated \fIlist\fR.  If x11vnc is not running as
-root this option is ignored.
-.IP
-Why use this option?  In general it is not needed since
-x11vnc is already connected to the X display and can
-perform its primary functions.  The option was added
-to make some of the *external* utility commands x11vnc
-occasionally runs work properly.  In particular under
-GNOME and KDE to implement the "\fB-solid\fR \fIcolor\fR" feature
-external commands (gconftool-2 and dcop) unfortunately
-must be run as the user owning the desktop session.
-Since this option switches userid it also affects the
-userid used to run the processes for the \fB-accept\fR and
-\fB-gone\fR options.  It also affects the ability to read
-files for options such as \fB-connect,\fR \fB-allow,\fR and \fB-remap\fR
-and also the ultra and tight filetransfer feature if
-enabled.  Note that the \fB-connect\fR file is also sometimes

-.IP
-So be careful with this option since in some situations
-its use can decrease security.
-.IP
-In general the switch to a user will only take place
-if the display can still be successfully opened as that
-user (this is primarily to try to guess the actual owner
-of the session). Example: "\fB-users\fR \fIfred,wilma,betty\fR".
-Note that a malicious local user "barney" by
-quickly using "xhost +" when logging in may possibly
-get the x11vnc process to switch to user "fred".
-What happens next?
-.IP
-Under display managers it may be a long time before
-the switch succeeds (i.e. a user logs in).  To instead
-make it switch immediately regardless if the display
-can be reopened prefix the username with the "+"
-character. E.g. "\fB-users\fR \fI+bob\fR" or "\fB-users\fR \fI+nobody\fR".
-.IP
-The latter (i.e. switching immediately to user
-"nobody") is the only obvious use of the \fB-users\fR option
-that increases security.
-.IP
-Use the following notation to associate a group with
-a user: user1.group1,user2.group2,...  Note that
-.IR initgroups (2)
-will still be called first to try to
-switch to ALL of a user's groups (primary and additional
-groups).  Only if that fails or it is not available
-then the single group specified as above (or the user's
-primary group if not specified) is switched to with
-.IR setgid (2).
-Use \fB-env\fR X11VNC_SINGLE_GROUP=1 to prevent
-trying 
-.IR initgroups (2)
-and only switch to the single
-group.  This sort of setting is only really needed to
-make the ultra or tight filetransfer permissions work
-properly. This format applies to any comma separated list

-.IP
-In \fB-unixpw\fR mode, if "\fB-users\fR \fIunixpw=\fR" is supplied

-If you want to limit which users this will be done for,
-provide them as a comma separated list after "unixpw="
-Groups can also be specified as described above.
-.IP
-Similarly, in \fB-ssl\fR mode, if "\fB-users\fR \fIsslpeer=\fR" is
-supplied then after an SSL client authenticates with his
-cert (the \fB-sslverify\fR option is required for this) x11vnc
-will extract a UNIX username from the "emailAddress"
-field (username@hostname.com) of the "Subject" of the
-x509 SSL cert and then try to switch to that user as
-though "\fB-users\fR \fI+username\fR" had been supplied.  If you
-want to limit which users this will be done for, provide
-them as a comma separated list after "sslpeer=".
-Set the env. var X11VNC_SSLPEER_CN to use the Common
-Name (normally a hostname) instead of the Email field.
-.IP
-NOTE: for sslpeer= mode the x11vnc administrator must
-take care that any client certs he adds to \fB-sslverify\fR
-have the intended UNIX username in the "emailAddress"
-field of the cert.  Otherwise a user may be able to
-log in as another.  This command can be of use in
-checking: "openssl x509 \fB-text\fR \fB-in\fR file.crt", see the
-"Subject:" line.  Also, along with the normal RFB_*
-env. vars. (see \fB-accept)\fR passed to external cmd=
-commands, RFB_SSL_CLIENT_CERT will be set to the

-.IP
-The sslpeer= mode can aid finding X sessions via the

-.IP
-To immediately switch to a user *before* connections
-to the X display are made or any files opened use the

-Even more sinister is the special user "lurk="
-that means to try to guess the DISPLAY from the utmpx
-login database as well.  So it "lurks" waiting for

-Specify a list of users after the = to limit which users

-.IP
-If the X display supports retrieving the cursor shape
-information from the X server, then the default is
-to use that mode.  On Solaris this can be done with
-the SUN_OVL extension using \fB-overlay\fR (see also the
-\fB-overlay_nocursor\fR option).  A similar overlay scheme
-is used on IRIX.  Xorg (e.g. Linux) and recent Solaris

-shift the tree depth.  On high latency links or slow
-machines there will be a time lag between expected and
-the actual cursor shape.
-.IP
-"\fB-cursor\fR \fIsome\fR" - like "X" but use additional

-useful in some situations because it provides a little
-more feedback about the cursor shape.
-.IP
-"\fB-cursor\fR \fImost\fR" - try to show as many cursors as

-always force positioning the mouse to the x,y position
-even if that position has not changed since the previous

-.IP
-The first place this problem was noticed was in gnome
-terminal: if you pressed and released mouse button 3, a
-menu was posted and then its first element 'New Terminal

-the mouse position twice: once on ButtonPress and again
-on ButtonRelease.  The toolkit interpreted the 2nd one
-as mouse motion even though the mouse hadn't moved.
-So now by default x11vnc tries to avoid injecting the
-2nd one.
-.IP
-Note that with the new default x11vnc will be oblivious
-to applications moving the pointer (warping) or the

-So for a short time there are two (or more) block

-.IP
-These transients are induced by the approximation of
-scroll detection (e.g. it detects the scroll, but not
-the fact that the block cursor was cleared just before
-the scroll).  In nearly all cases these transient errors
-are repaired when the true X framebuffer is consulted
-by the normal polling.  But they are distracting, so
-what this option provides is extra "padding" near the

-.IP
-x11vnc's use of the DAMAGE extension: 1) significantly
-reduces the load when the screen is not changing much,
-and 2) detects changed areas (small ones by default)
-more quickly.
-.IP
-Currently the DAMAGE extension is overly conservative
-and often reports large areas (e.g. a whole terminal

-changed region is much smaller (sometimes just a few
-pixels).  So heuristics were introduced to skip large
-areas and use the damage rectangles only as "hints"
-for the traditional scanline polling.  The following
-tuning parameters are introduced to adjust this
-behavior:
-.PP
-\fB-xd_area\fR \fIA\fR
-.IP
-Set the largest DAMAGE rectangle area \fIA\fR (in
-pixels: width * height) to trust as truly damaged:
-the rectangle will be copied from the framebuffer
-(slow) no matter what.  Set to zero to trust *all*
-rectangles. Default: 20000
-.PP
-\fB-xd_mem\fR \fIf\fR
-.IP
-Set how long DAMAGE rectangles should be "remembered",
-\fIf\fR is a floating point number and is in units of the
-scanline repeat cycle time (32 iterations).  The default

-there are problems or decrease it to live on the edge
-(perhaps useful on a slow machine).
-.PP
-\fB-sigpipe\fR \fIstring\fR
-.IP
-Broken pipe (SIGPIPE) handling.  \fIstring\fR can be
-"ignore" or "exit".  For "ignore" LibVNCServer
-will handle the abrupt loss of a client and continue,
-for "exit" x11vnc will cleanup and exit at the 1st
-broken connection.

-This option is not really needed since LibVNCServer

-A more sophisticated video device scheme allows

-.IP
-\fB-rawfb\fR video:<settings>
-.IP
-The prefix could also be, as above, e.g. "video1:" to
-specify the device file.  The v4l API must be available
-for this to work.  Otherwise, you will need to try
-to initialize the device with an external program,
-e.g. xawtv, spcaview, and hope they persist when x11vnc
-re-opens the device.
-.IP
-<settings> is a comma separated list of key=value pairs.
-The device's brightness, color, contrast, and hue can
-be set to percentages, e.g. br=80,co=50,cn=44,hu=60.
-.IP
-The device filename can be set too if needed (if it
-does not start with "video"), e.g. fn=/dev/qcam.
-.IP
-The width, height and bpp of the framebuffer can be
-set via, e.g., w=160,h=120,bpp=16.

-Related to the bpp above, the pixel format can be set
-via the fmt=XXX, where XXX can be one of: GREY, HI240,

-For TV/rf tuner cards one can set the tuning mode
-via tun=XXX where XXX can be one of PAL, NTSC, SECAM,

-.IP
-One can switch the input channel by the inp=XXX setting,
-where XXX is the name of the input channel (Television,

-.IP
-For input channels with tuners (e.g. Television) one
-can change which station is selected by the sta=XXX
-setting.  XXX is the station number.  Currently only
-the ntsc-cable-us (US cable) channels are built into
-x11vnc.  See the \fB-freqtab\fR option below to supply one

-Example:
-.IP
-\fB-rawfb\fR video:br=80,w=320,h=240,fmt=RGB32,tun=NTSC,sta=47

-LINUX CONSOLE:  The following describes some ways to
-view and possibly interact with the Linux text/graphics
-console (i.e. not X11 XFree86/Xorg)
-.IP
-Note: If the LibVNCServer LinuxVNC program is on your
-system you may want to use that instead of the following
-method because it will be faster and more accurate
-for the Linux text console and includes mouse support.
-There is, however, the basic LinuxVNC functionality in
-x11vnc if you replace "console" with "vt" in the
-examples below.
-.IP
-If the rawfb string begins with "console" the
-framebuffer device /dev/fb0 is opened and /dev/tty0 is
-opened too.  The latter is used to inject keystrokes
-(not all are supported, but the basic ones are).
-You will need to be root to inject keystrokes, but
-not necessarily to open /dev/fb0.  /dev/tty0 refers to
-the active VT, to indicate one explicitly, use, e.g.,
-"console2" for /dev/tty2, etc. by indicating the
-specific VT number.
-.IP
-For the Linux framebuffer device, /dev/fb0, (fb1,
-etc) to be enabled the appropriate kernel drivers must
-be loaded.  E.g. vesafb or vga16fb and also by setting
-the boot parameter vga=0x301 (or 0x314, 0x317, etc.)
-(The vga=... method is the preferred way; set your
-machines up that way.)  Otherwise there will be a
-\'No such device' error.  You can also load a Linux
-framebuffer driver specific to your make of video card
-for more functionality.  Once the machine is booted one
-can often 'modprobe' the fb driver as root to obtain
-a framebuffer device.
-.IP
-If you cannot get /dev/fb0 working on Linux, try
-using the LinuxVNC emulation mode by "\fB-rawfb\fR \fIvtN\fR"
-where N = 1, ... 6 is the Linux Virtual Terminal (aka
-virtual console) you wish to view, e.g. "\fB-rawfb\fR \fIvt2\fR".
-Unlike /dev/fb mode, it need not be the active Virtual
-Terminal.  Note that this mode can only show text and
-not graphics.  x11vnc polls the text in /dev/vcsaN
-.IP
-Set the env. var. RAWFB_VCSA_BW=1 to disable colors in
-the "vtN" mode (i.e. black and white only.)  If you
-do not prefer the default 16bpp set RAWFB_VCSA_BPP to
-8 or 32.  If you need to tweak the rawfb parameters by
-using the 'console_guess' string printed at startup,
-be sure to indicate the snap: method.
-.IP
-uinput: If the Linux version appears to be 2.6
-or later and the "uinput" module appears to be
-present (modprobe uinput), then the uinput method
-will be used instead of /dev/ttyN.  uinput allows
-insertion of BOTH keystrokes and mouse input and so it
-preferred when accessing graphical (e.g. QT-embedded)
-linux console apps.  It also provides more accurate
-keystroke insertion.  See \fB-pipeinput\fR UINPUT below for
-more information on this mode; you will have to use
-\fB-pipeinput\fR if you want to tweak any UINPUT parameters.
-You may also want to also use the \fB-nodragging\fR and
-\fB-cursor\fR none options.  Use "console0", etc  or
-\fB-pipeinput\fR CONSOLE to force the /dev/ttyN method.
-.IP
-Note you can change the Linux VT remotely using the
-.IR chvt (1)
-command to make the one you want be the active
-one (e.g. 'chvt 3').  Sometimes switching out and back
-corrects the framebuffer's graphics state.  For the
-"\fB-rawfb\fR \fIvtN\fR" mode there is no need to switch the VT's.
-.IP
-To skip input injecting entirely use "consolex"
-or "vtx".
-.IP
-The string "/dev/fb0" (1, etc.) can be used instead
-of "console".  This can be used to specify a different
-framebuffer device, e.g. /dev/fb1.  As a shortcut the
-"/dev/" can be dropped.  If the name is something
-nonstandard, use "console:/dev/foofb"
-.IP
-If you do not want x11vnc to guess the framebuffer's
-WxHxB and masks automatically (sometimes the kernel
-gives incorrect information), specify them with a @WxHxB
-(and optional :R/G/B masks) at the end of the string.

-VNC HOST: if the \fB-rawfb\fR string is of the form
-"vnc:host:N" then the VNC display "N" on the remote
-VNC server "host" is connected to (i.e. x11vnc acts as
-a VNC client itself) and that framebuffer is exported.
-.IP
-This mode is really only of use if you are trying
-to improve performance in the case of many (e.g. >
-10) simultaneous VNC viewers, and you try a divide
-and conquer scheme to reduce bandwidth and improve
-responsiveness.  (However, another user found this mode
-useful to export a demo display through a slow link:
-then multiple demo viewers connected to the reflecting
-x11vnc on the fast side of the link, and so avoided
-all of the demo viewers going through the slow link.)
-.IP
-For example, if there will be 64 simultaneous VNC
-viewers this can lead to a lot of redundant VNC traffic
-to and from the server host:N, extra CPU usage,
-and all viewers response can be reduced by having
-to wait for writes to the slowest client to finish.
-However, if you set up 8 reflectors/repeaters started
-with option \fB-rawfb\fR vnc:host:N, then there are only
-8 connections to host:N.  Each repeater then handles
-8 vnc viewer connections thereby spreading the load
-around.  In classroom broadcast usage, try to put the
-repeaters on different switches.  This mode is the same
-as \fB-reflect\fR host:N.  Replace "host:N" by "listen"
-or "listen:port" for a reverse connection.
-.IP
-Overall performance will not be as good as a single
-direct connection because, among other things,
-there is an additional level of framebuffer polling
-and pointer motion can still induce many changes per
-second that must be propagated.  Tip: if the remote VNC
-is x11vnc doing wireframing, or an X display that does
-wireframing that gives much better response than opaque
-window dragging.  Consider the \fB-nodragging\fR option if
-the problem is severe.

-If cmd is "CONSOLE" or "CONSOLEn" where n
-is a Linux console number, then the linux console
-keystroke insertion to /dev/ttyN (see \fB-rawfb\fR console)
-is performed.
-.IP
-If cmd begins with "UINPUT" then the Linux uinput
-module is used to insert both keystroke and mouse events
-to the Linux console (see \fB-rawfb\fR above).  This usually
-is the /dev/input/uinput device file (you may need to
-create it with "mknod /dev/input/uinput c 10 223"
-and insert the module with "modprobe uinput".
-.IP
-The UINPUT mode currently only does US keyboards (a
-scan code option may be added), and not all keysyms
-are supported.  But it is probably more accurate than
-the "CONSOLE" method.
-.IP
-You may want to use the options \fB-cursor\fR none and
-\fB-nodragging\fR in this mode.
-.IP
-Additional tuning options may be supplied via:
-UINPUT:opt1,opt2,... (a comma separated list). If an
-option begins with "/" it is taken as the uinput
-device file.
-.IP
-Which uinput is injected can be controlled by an option
-string made of the characters "K", "M", and "B"
-(see the \fB-input\fR option), e.g. "KM" allows keystroke
-and motion but not button clicks.
-.IP
-A UINPUT option of the form: accel=f, or accel=fx+fy
-sets the mouse motion "acceleration".  This is used
-to correct raw mouse relative motion into how much the
-application cursor moves (x11vnc has no control over,
-or knowledge of how the windowing application interprets
-the raw mouse motions).  Typically the acceleration
-for an X display is 2 (see xset "m" option).  "f"
-is a floating point number, e.g. 3.0.  Use "fx+fy"
-if you need to supply different corrections for x and y.
-.IP
-Note: the default acceleration is 2.0 since it seems
-both X and qt-embedded often (but not always) use
-this value.
-.IP
-Even with a correct accel setting the mouse position
-will get out of sync (probably due to a mouse
-"threshold" setting where the acceleration doe not
-apply, set 
-.IR xset (1)
-).  The option reset=N sets the
-number of ms (default 150) after which the cursor is
-attempted to be reset (by forcing the mouse to (0,
-0) via small increments and then back out to (x, y)
-in 1 jump), This correction seems to be needed but can
-cause jerkiness or unexpected behavior with menus, etc.
-Use reset=0 to disable.
-.IP
-If you set the env. var X11VNC_UINPUT_THRESHOLDS then
-the thresh=n mode will be enabled.  It is currently
-not working well.  If |dx| <= thresh and |dy| < thresh
-no acceleration is applied.  Use "thresh=+n" |dx| +
-|dy| < thresh to be used instead (X11?)
-.IP
-Example:
-\fB-pipeinput\fR UINPUT:accel=4.0 \fB-cursor\fR none
-.IP
-If the uinput device has an absolute pointer (as opposed
-to a normal mouse that is a relative pointer) you can
-specify the option "abs".  Note that a touchpad
-on a laptop is an absolute device to some degree.
-This (usually) avoids all the problems with mouse
-acceleration.  If x11vnc has trouble deducing the
-size of the device, use "abs=WxH".  Furthermore,
-if the device is a touchscreen (assumed to have an
-absolute pointer) use "touch" or "touch=WxH".
-For touchscreens, when a mouse button is pressed,
-a pressure increase is injected, and when the button
-is released a pressure of zero is injected.
-.IP
-If touch has been set, use "touch_always=1" to
-indicate whenever the mouse moves with no button
-pressed, a touch event of zero pressure should be
-sent anyway.  Also use "btn_touch=1" to indicate a
-BTN_TOUCH keystroke press or release should be sent
-instead of a pressure change.  Set "dragskip=n" to
-skip n dragged mouse touches (with pressure applied)
-before injecting one.  To indicate the pressure that
-should be sent when there is a button click for a
-touchscreen device, specify pressure=n, e.g. n=5. The
-default is n=1.
-.IP
-If a touch screen is being used ("touch" above)
-and it is having its input processed by tslib, you can
-specify the tslib calibration file via tslib_cal=<file>.
-For example, tslib_cal=/etc/pointercal.  To get accurate
-or even usable positioning this is required when tslib
-is in use.
-.IP
-The Linux uinput mechanism can be bypassed and one can
-write input events DIRECTLY to the devices instead.
-To do this, specify one or more of the following
-for the input classes: direct_rel=<device>
-direct_abs=<device> direct_btn=<device> or
-direct_key=<device>.  The <device> file is usually
-something like /dev/input/event1 but you can specify
-any device file or pipe.  You must specify each one
-of the above classes even if they correspond to the
-same device file (rel/abs and btn are often the same.)
-Look at the file /proc/bus/input/devices to get an idea
-what is available and the device filenames.  Note:
-The /dev/input/mouse* devices do not seem to work,
-use the corresponding /dev/input/event* file instead.
-Any input class not directly specified as above will be
-handled via the uinput mechanism.  To disable creating a
-uinput device (and thereby discarding unhandled input),
-specify "nouinput".
-.IP
-Examples:
-.IP
-\fB-pipeinput\fR UINPUT:direct_abs=/dev/input/event1
-.IP
-this was used on a qtmoko Neo freerunner (armel):
-.IP
-\fB-pipeinput\fR UINPUT:touch,tslib_cal=/etc/pointercal,
-direct_abs=/dev/input/event1,nouinput,dragskip=4
-.IP
-(where the long line has been split into two.)

-\fB-gui\fR \fI[gui-opts]\fR

-Start up a simple tcl/tk gui based on the remote
-control options \fB-remote/-query\fR described below.
-Requires the "wish" program to be installed on the
-machine.  "gui-opts" is not required: the default
-is to start up both the full gui and x11vnc with the
-gui showing up on the X display in the environment
-variable DISPLAY.
-.IP
-"gui-opts" can be a comma separated list of items.
-Currently there are these types of items: 1) a gui
-mode, a 2) gui "simplicity", 3) the X display the
-gui should display on, 4) a "tray" or "icon" mode,
-and 5) a gui geometry.
-.IP
-1) The gui mode can be "start", "conn", or "wait"
-"start" is the default mode above and is not required.
-"conn" means do not automatically start up x11vnc,
-but instead just try to connect to an existing x11vnc
-process.  "wait" means just start the gui and nothing
-else (you will later instruct the gui to start x11vnc
-or connect to an existing one.)
-.IP
-2) The gui simplicity is off by default (a power-user
-gui with all options is presented) To start with
-something less daunting supply the string "simple"
-("ez" is an alias for this).  Once the gui is
-started you can toggle between the two with "Misc ->
-simple_gui".
-.IP
-3) Note the possible confusion regarding the potentially
-two different X displays: x11vnc polls one, but you
-may want the gui to appear on another.  For example, if
-you ssh in and x11vnc is not running yet you may want
-the gui to come back to you via your ssh redirected X
-display (e.g. localhost:10).
-.IP
-If you do not specify a gui X display in "gui-opts"
-then the DISPLAY environment variable and \fB-display\fR
-option are tried (in that order).  Regarding the x11vnc
-X display the gui will try to communication with, it
-first tries \fB-display\fR and then DISPLAY.  For example,
-"x11vnc \fB-display\fR :0 \fB-gui\fR otherhost:0", will remote
-control an x11vnc polling :0 and display the gui on
-otherhost:0 The "tray/icon" mode below reverses this
-preference, preferring to display on the x11vnc display.
-.IP
-4) When "tray" or "icon" is specified, the gui
-presents itself as a small icon with behavior typical
-of a "system tray" or "dock applet".  The color
-of the icon indicates status (connected clients) and
-there is also a balloon status.  Clicking on the icon
-gives a menu from which properties, etc, can be set and
-the full gui is available under "Advanced".  To be
-fully functional, the gui mode should be "start"
-(the default).
-.IP
-Note that tray or icon mode will imply the \fB-forever\fR
-x11vnc option (if the x11vnc server is started along
-with the gui) unless \fB-connect\fR or \fB-connect_or_exit\fR has
-been specified.  So x11vnc (and the tray/icon gui)
-will wait for more connections after the first client
-disconnects.  If you want only one viewer connection
-include the \fB-once\fR option.
-.IP
-For "icon" the gui just a small standalone window.
-For "tray" it will attempt to embed itself in the
-"system tray" if possible. If "=setpass" is appended then
-at startup the X11 user will be prompted to set the
-VNC session password.  If =<hexnumber> is appended
-that icon will attempt to embed itself in the window
-given by hexnumber.  Use =noadvanced to disable the
-full gui. (To supply more than one, use "+" sign).
-E.g. \fB-gui\fR tray=setpass and \fB-gui\fR icon=0x3600028
-.IP
-Other modes: "full", the default and need not be
-specified.  "\fB-gui\fR \fInone\fR", do not show a gui, useful
-to override a ~/.x11vncrc setting, etc.
-.IP
-5) When "geom=+X+Y" is specified, that geometry
-is passed to the gui toplevel.  This is the icon in
-icon/tray mode, or the full gui otherwise.  You can
-also specify width and height, i.e. WxH+X+Y, but it
-is not recommended.  In "tray" mode the geometry is
-ignored unless the system tray manager does not seem
-to be running.  One could imagine using something like
-"\fB-gui\fR \fItray,geom=+4000+4000\fR" with a display manager
-to keep the gui invisible until someone logs in...
-.IP
-More icon tricks, "icon=minimal" gives an icon just
-with the VNC display number.  You can also set the font
-with "iconfont=...".  The following could be useful:
-"\fB-gui\fR \fIicon=minimal,iconfont=5x8,geom=24x10+0-0\fR"
-.IP
-General examples of the \fB-gui\fR option: "x11vnc \fB-gui",\fR
-"x11vnc \fB-gui\fR ez" "x11vnc \fB-gui\fR localhost:10",
-"x11vnc \fB-gui\fR conn,host:0", "x11vnc \fB-gui\fR tray,ez"
-"x11vnc \fB-gui\fR tray=setpass"
-.IP
-If you do not intend to start x11vnc from the gui
-(i.e. just remote control an existing one), then the
-gui process can run on a different machine from the
-x11vnc server as long as X permissions, etc. permit
-communication between the two.
-.IP
-FONTS: On some systems the tk fonts can be too small,
-jagged, or otherwise unreadable.  There are 4 env vars
-you can set to be the tk font you prefer:
-.IP
-X11VNC_FONT_BOLD   main font for menus and buttons.
-X11VNC_FONT_FIXED  font for fixed width text.

-The default communication channel is that of X

-The running server cannot use the \fB-novncconnect\fR option
-because that disables the communication channel.
-See below for alternate channels.
-.IP
-For example: 'x11vnc \fB-remote\fR stop' (which is the same as

-bcx_xattach:str  This remote control command is for
-use with the BARCO xattach program or the x2x program.
-Both of these programs are for 'pointer and keyboard'
-sharing between separate X displays.  In general the
-two displays are usually nearby, e.g. on the same desk,
-and this allows the user to share a single pointer and
-keyboard between them.  The user moves the mouse to
-an edge and then the mouse pointer appears to 'jump'
-to the other display screen.  Thus it emulates what a
-single X server would do for two screens (e.g. :0.0 and
-:0.1) The illusion of a single Xserver with multiple
-screens is achieved by forwarding events to the 2nd
-one via the XTEST extension.
-.IP
-What the x11vnc bcx_xattach command does is to perform
-some pointer movements to try to INDUCE xattach/x2x
-to 'jump' to the other display.  In what follows the
-\'master' display refers to the one that when it has
-\'focus' it is basically doing nothing besides watching
-for the mouse to go over an edge.  The 'slave'
-display refers to the one to which the mouse and
-keyboard is redirected to once an edge in the master
-has been crossed.  Note that the x11vnc executing the
-bcx_xattach command MUST be the one connected to the
-*master* display.
-.IP
-Also note that when input is being redirected (via
-XTEST) from the master display to the slave display,
-the master display's pointer and keyboard are *grabbed*
-by xattach/x2x.  x11vnc can use this info to verify that
-the master/slave mode change has taken place correctly.
-If you specify the "ifneeded" option (see below)
-and the initial grab state is that of the desired
-final state, then no pointer movements are injected
-and "DONE,GRAB_OK" is returned.
-.IP
-"str" must contain one of "up", "down", "left",
-or "right" to indicate the direction of the 'jump'.
-"str" must also contain one of "master_to_slave"
-or "slave_to_master" to indicate the type of mode
-change induced by the jump.  Use "M2S" and "S2M"
-as shorter aliases.
-.IP
-"str" may be a "+" separated list of additional
-tuning options.  The "shift=n" option indicates an
-offset shift position away from (0,0) (default 20).
-"final=x+y" specifies the final position of the cursor
-at the end of the normal move sequence; default 30+30.
-"extra_move=x+y" means to do one more pointer move
-after "final" to x+y.  "dt=n" sets the sleep time
-in milliseconds between pointer moves (default: 40ms)
-"retry=n" specifies the maximum number of retries if
-the grab state change fails. "ifneeded" means to not
-apply the pointer movements if the initial grab state is
-that of the desired final state. "nograbcheck" means
-to not check if the grab state changed as expected and
-only apply the pointer movements (default is to check
-the grab states.)
-.IP
-If you do not specify "up", etc., to bcx_xattach
-nothing will be attempted and the command returns
-the string FAIL,NO_DIRECTION_SPECIFIED.  If you do
-not specify "master_to_slave" or "M2S", etc., to
-bcx_xattach nothing will be attempted and the command
-returns the string FAIL,NO_MODE_CHANGE_SPECIFIED.
-.IP
-Otherwise, the returned string will contain "DONE".
-It will be "DONE,GRAB_OK" if the grab state changed
-as expected (or if "ifneeded" was supplied and
-the initial grab state was already the desired
-one.)  If the initial grab state was incorrect,
-but the final grab state was correct then it is
-"DONE,GRAB_FAIL_INIT".  If the initial grab state
-was correct, but the final grab state was incorrect
-then it is "DONE,GRAB_FAIL_FINAL".  If both are
-incorrect it will be "DONE,GRAB_FAIL".  Under grab
-failure the string will be followed by ":p1,k1-p2,k2"
-where  p1,k1 indicates the initial pointer and keyboard
-grab states and p2,k2 the final ones. If GRAB_FAIL or
-GRAB_FAIL_FINAL occurs, the action will be retried up
-to 3 times; trying to reset the state and sleeping a
-bit between each try.  Set retry=n to adjust the number
-of retries, zero to disable retries.

-Examples:
-\fB-R\fR bcx_xattach:down+M2S
-\fB-R\fR bcx_xattach:up+S2M
-\fB-R\fR bcx_xattach:up+S2M+nograbcheck+dt=30
-\fB-R\fR bcx_xattach:down+M2S+extra_move=100+100
-.IP
-or use \fB-Q\fR instead of \fB-R\fR to retrieve the result text.
-.IP
-End of the bcx_xattach:str description.
-.IP
-The 
-.IR vncconnect (1)
-command from standard VNC
-distributions may also be used if string is prefixed
-with "cmd=" E.g. 'vncconnect cmd=stop'.  Under some
-circumstances 
-.IR xprop (1)
-can used if it supports \fB-set\fR
-(see the FAQ).
-.IP
-If "\fB-connect\fR \fI/path/to/file\fR" has been supplied to the
-running x11vnc server then that file can be used as a
-communication channel (this is the only way to remote
-control one of many x11vnc's polling the same X display)
-Simply run: 'x11vnc \fB-connect\fR /path/to/file \fB-remote\fR ...'
-or you can directly write to the file via something
-like: "echo cmd=stop > /path/to/file", etc.
-.PP
-\fB-query\fR \fIvariable\fR
-.IP
-Like \fB-remote,\fR except just query the value of
-\fIvariable\fR.  "\fB-Q\fR" is an alias for "\fB-query\fR".
-Multiple queries can be done by separating variables
-by commas, e.g. \fB-query\fR var1,var2. The results come
-back in the form ans=var1:value1,ans=var2:value2,...
-to the standard output.  If a variable is read-only,
-it comes back with prefix "aro=" instead of "ans=".
-.IP
-Some \fB-remote\fR commands are pure actions that do not make
-sense as variables, e.g. "stop" or "disconnect", in
-these cases the value returned is "N/A".  To direct a
-query straight to the X11VNC_REMOTE property or connect
-file use "qry=..." instead of "cmd=..."

-.PP
-\fB-QD\fR \fIvariable\fR
-.IP
-Just like \fB-query\fR variable, but returns the default
-value for that parameter (no running x11vnc server
-is consulted)
-.PP
-\fB-sync\fR
-.IP
-By default \fB-remote\fR commands are run asynchronously, that
-is, the request is posted and the program immediately
-exits.  Use \fB-sync\fR to have the program wait for an
-acknowledgement from the x11vnc server that command was
-processed (somehow).  On the other hand \fB-query\fR requests
-are always processed synchronously because they have
-to wait for the answer.
-.IP
-Also note that if both \fB-remote\fR and \fB-query\fR requests are
-supplied on the command line, the \fB-remote\fR is processed
-first (synchronously: no need for \fB-sync),\fR and then
-the \fB-query\fR request is processed in the normal way.
-This allows for a reliable way to see if the \fB-remote\fR
-command was processed by querying for any new settings.
-Note however that there is timeout of a few seconds
-(see the next paragraph) so if the x11vnc takes longer
-than that to process the requests the requester will
-think that a failure has taken place.
-.IP
-The default is to wait 3.5 seconds.  Or if cmd=stop
-only 1.0 seconds.  If cmd matches 'script:' then it
-will wait up to 10.0 seconds.  Set X11VNC_SYNC_TIMEOUT
-to the number of seconds you want it to wait.
-.PP
-\fB-query_retries\fR \fIstr\fR
-.IP
-If a query fails to get a response from an x11vnc
-server, retry up to n times.  \fIstr\fR is specified as
-n[:t][/match]  Optionally the delay between tries may
-be specified by "t" a floating point time (default
-0.5 seconds.)  Note: the response is not checked for
-validity or whether it corresponds to the query sent.
-The query "ping:mystring" may be used to help uniquely
-identify the query.  Optionally, a matching string after
-a "/" will be used to check the result text.  Up to
-n retries will take place until the matching string is
-found in the output text.  If the match string is never
-found the program's exit code is 1; if the match is
-found it exits with 0.  Note that there may be stdout
-printed for each retry (i.e. multiple lines printed
-out to stdout.)
-Example: \fB-query_retries\fR 4:1.5/grab_state
-.PP
-\fB-remote_prefix\fR \fIstr\fR
-.IP
-Enable a remote-control communication channel for
-connected VNC clients.  str is a non-empty string. If a
-VNC client sends rfbCutText having the prefix \fIstr\fR
-then the part after it is processed as though it were
-sent via 'x11vnc \fB-remote\fR ...'.  If it begins with
-neither 'cmd=' nor 'qry=' then 'qry=' is assumed.
-Any corresponding output text for that remote control
-command is sent back to all client as rfbCutText.
-The returned output is also prefixed with \fIstr\fR.
-Example: \fB-remote_prefix\fR DO_THIS:
-.IP
-Note that enabling \fB-remote_prefix\fR allows the remote
-VNC viewers to run x11vnc \fB-remote\fR commands.  Do not
-use this option if they are not to be trusted.
-.PP
-\fB-noremote,\fR \fB-yesremote\fR
-.IP
-Do not process any remote control commands or queries.
-Do process remote control commands or queries.
-Default: \fB-yesremote\fR
-.IP
-A note about security wrt remote control commands.
-If someone can connect to the X display and change
-the property X11VNC_REMOTE, then they can remotely
-control x11vnc.  Normally access to the X display is
-protected.  Note that if they can modify X11VNC_REMOTE
-on the X server, they have enough permissions to also
-run their own x11vnc and thus have complete control
-of the desktop.  If the  "\fB-connect\fR \fI/path/to/file\fR"
-channel is being used, obviously anyone who can write
-to /path/to/file can remotely control x11vnc.  So be
-sure to protect the X display and that file's write
-permissions.  See \fB-privremote\fR below.
-.IP
-If you are paranoid and do not think \fB-noremote\fR is
-enough, to disable the X11VNC_REMOTE property channel
-completely use \fB-novncconnect,\fR or use the \fB-safer\fR option
-that shuts many things off.
-.PP
-\fB-unsafe\fR
-.IP
-A few remote commands are disabled by default
-(currently: id:pick, accept:<cmd>, gone:<cmd>, and
-rawfb:setup:<cmd>) because they are associated with
-running external programs.  If you specify \fB-unsafe,\fR then
-these remote-control commands are allowed.  Note that
-you can still specify these parameters on the command
-line, they just cannot be invoked via remote-control.
-.PP
-\fB-safer\fR
-.IP
-Equivalent to: \fB-novncconnect\fR \fB-noremote\fR and prohibiting
-\fB-gui\fR and the \fB-connect\fR file. Shuts off communcation
-channels.
-.PP
-\fB-privremote\fR
-.IP
-Perform some sanity checks and disable remote-control
-commands if it appears that the X DISPLAY and/or
-connectfile can be accessed by other users.  Once
-remote-control is disabled it cannot be turned back on.
-.PP
-\fB-nocmds\fR
-.IP
-No external commands (e.g. 
-.IR system (3)
-, 
-.IR popen (3)
-, 
-.IR exec (3)
-)
-will be run at all.
-.PP
-\fB-allowedcmds\fR \fIlist\fR
-.IP
-\fIlist\fR contains a comma separated list of the only
-external commands that can be run.  The full list of
-associated options is:
-.IP
-stunnel, ssl, unixpw, WAIT, zeroconf, id, accept,
-afteraccept, gone, pipeinput, v4l-info, rawfb-setup,
-dt, gui, ssh, storepasswd, passwdfile, custom_passwd,
-findauth, crash.
-.IP
-See each option's help to learn the associated external
-command.  Note that the \fB-nocmds\fR option takes precedence
-and disables all external commands.
-.PP
-\fB-deny_all\fR
-.IP
-For use with \fB-remote\fR nodeny: start out denying all
-incoming clients until "\fB-remote\fR \fInodeny\fR" is used to
-let them in.
-.PP

-/*
- * This program is based on some ideas from the following programs:
- *
- *       the initial x11vnc.c in libvncserver (Johannes E. Schindelin)
- *	 x0rfbserver, the original native X vnc server (Jens Wagner)
- *       krfb, the KDE desktopsharing project (Tim Jansen)
- *
- * Please see http://www.karlrunge.com/x11vnc for the most up-to-date
- * information about x11vnc.  Some of the following text may be out
- * of date.
- *
- * The primary goal of this program is to create a portable and simple
- * command-line server utility that allows a VNC viewer to connect
- * to an actual X display (as the above do).  The only non-standard
- * dependency of this program is the static library libvncserver.a.
- * Although in some environments libjpeg.so or libz.so may not be
- * readily available and needs to be installed, they may be found
- * at ftp://ftp.uu.net/graphics/jpeg/ and http://www.gzip.org/zlib/,
- * respectively.  To increase portability it is written in plain C.
- *
- * Another goal is to improve performance and interactive response.
- * The algorithm of x0rfbserver was used as a base.  Many additional
- * heuristics are also applied.
- *
- * Another goal is to add many features that enable and incourage creative
- * usage and application of the tool.  Apologies for the large number
- * of options!
- *
- * To build:
- *
- * Obtain the libvncserver package (http://libvncserver.sourceforge.net).
- * As of 12/2002 this version of x11vnc.c is contained in the libvncserver
- * CVS tree and released in version 0.5.
- *
- * gcc should be used on all platforms.  To build a threaded version put
- * "-D_REENTRANT -DX11VNC_THREADED" in the environment variable CFLAGS
- * or CPPFLAGS (e.g. before running the libvncserver configure).  The
- * threaded mode is a bit more responsive, but can be unstable (e.g.
- * if more than one client the same tight or zrle encoding).
- *
- * Known shortcomings:
- *
- * The screen updates are good, but of course not perfect since the X
- * display must be continuously polled and read for changes and this is
- * slow for most hardware. This can be contrasted with receiving a change
- * callback from the X server, if that were generally possible... (UPDATE:
- * this is handled now with the X DAMAGE extension, but unfortunately
- * that doesn't seem to address the slow read from the video h/w).  So,
- * e.g., opaque moves and similar window activity can be very painful;
- * one has to modify one's behavior a bit.
- *
- * General audio at the remote display is lost unless one separately
- * sets up some audio side-channel such as esd.
- *
- * It does not appear possible to query the X server for the current
- * cursor shape.  We can use XTest to compare cursor to current window's
- * cursor, but we cannot extract what the cursor is... (UPDATE: we now
- * use XFIXES extension for this.  Also on Solaris and IRIX Overlay
- * extensions exists that allow drawing the mouse into the framebuffer)
- * 
- * The current *position* of the remote X mouse pointer is shown with
- * the -cursor option.  Further, if -cursor X is used, a trick
- * is done to at least show the root window cursor vs non-root cursor.
- * (perhaps some heuristic can be done to further distinguish cases...,
- * currently "-cursor some" is a first hack at this)
- *
- * Under XFIXES mode for showing the cursor shape, the cursor may be
- * poorly approximated if it has transparency (alpha channel).
- *
- * Windows using visuals other than the default X visual may have
- * their colors messed up.  When using 8bpp indexed color, the colormap
- * is attempted to be followed, but may become out of date.  Use the
- * -flashcmap option to have colormap flashing as the pointer moves
- * windows with private colormaps (slow).  Displays with mixed depth 8 and
- * 24 visuals will incorrectly display windows using the non-default one.
- * On Sun and Sgi hardware we can to work around this with -overlay.
- *
- * Feature -id <windowid> can be picky: it can crash for things like
- * the window not sufficiently mapped into server memory, etc (UPDATE:
- * we now use the -xrandr mechanisms to trap errors more robustly for
- * this mode).  SaveUnders menus, popups, etc will not be seen.
- *
- * Under some situations the keysym unmapping is not correct, especially
- * if the two keyboards correspond to different languages.  The -modtweak
- * option is the default and corrects most problems. One can use the
- * -xkb option to try to use the XKEYBOARD extension to clear up any
- * remaining problems.
- *
- * Occasionally, a few tile updates can be missed leaving a patch of
- * color that needs to be refreshed.  This may only be when threaded,
- * which is no longer the default.
- *
- * There seems to be a serious bug with simultaneous clients when
- * threaded, currently the only workaround in this case is -nothreads
- * (which is now the default).
