- * wants to be doing as well. It is important to understand this difference
- * as we may wish to be processing data streams based on our desired state
- * (want_state) or based on what the peer thinks the state is (my_state).
- *
- * This all works fine because if the peer sends a positive request, the data
- * that we receive prior to negative acknowlegment will probably be affected
- * by the positive state, and we can process it as such (if we can; if we
- * can't then it really doesn't matter). If it is that important, then the

-.Sh NAME
-.Nm telnetd
-.Nd DARPA
-.Tn TELNET
-protocol server
-.Sh SYNOPSIS
-.Nm /usr/libexec/telnetd
-.Op Fl BUhlkns
-.Op Fl D Ar debugmode
-.Op Fl I Ns Ar initid
-.Op Fl S Ar tos
-.Op Fl X Ar authtype
-.Op Fl a Ar authmode
-.Op Fl edebug
-.Op Fl P Ar loginprog
-.Op Fl r Ns Ar lowpty-highpty
-.Op Fl u Ar len
-.Op Fl debug Op Ar port
-.Sh DESCRIPTION
-The
-.Nm telnetd
-command is a server which supports the
-.Tn DARPA
-standard
-.Tn TELNET
-virtual terminal protocol.
-.Nm Telnetd
-is normally invoked by the internet server (see
-.Xr inetd 8 )
-for requests to connect to the
-.Tn TELNET
-port as indicated by the
-.Pa /etc/services
-file (see
-.Xr services 5 ) .
-The
-.Fl debug
-option may be used to start up
-.Nm telnetd
-manually, instead of through
-.Xr inetd 8 .
-If started up this way,
-.Ar port
-may be specified to run
-.Nm telnetd
-on an alternate
-.Tn TCP
-port number.
-.Pp
-The
-.Nm telnetd
-command accepts the following options:
-.Bl -tag -width "-a authmode"
-.It Fl a Ar authmode
-This option may be used for specifying what mode should
-be used for authentication.
-Note that this option is only useful if
-.Nm telnetd
-has been compiled with support for the
-.Dv AUTHENTICATION
-option.
-There are several valid values for
-.Ar authmode:
-.Bl -tag -width debug
-.It debug
-Turns on authentication debugging code.
-.It user
-Only allow connections when the remote user
-can provide valid authentication information
-to identify the remote user,
-and is allowed access to the specified account
-without providing a password.
-.It valid
-Only allow connections when the remote user
-can provide valid authentication information
-to identify the remote user.
-The
-.Xr login 1
-command will provide any additional user verification
-needed if the remote user is not allowed automatic
-access to the specified account.
-.It other
-Only allow connections that supply some authentication information.
-This option is currently not supported
-by any of the existing authentication mechanisms,
-and is thus the same as specifying
-.Fl a
-.Cm valid .
-.It none
-This is the default state.
-Authentication information is not required.
-If no or insufficient authentication information
-is provided, then the
-.Xr login 1
-program will provide the necessary user
-verification.
-.It off
-This disables the authentication code.
-All user verification will happen through the
-.Xr login 1
-program.
-.El
-.It Fl B
-Specifies bftp server mode. In this mode,
-.Nm telnetd
-causes login to start a
-.Xr bftp 1
-session rather than the user's
-normal shell. In bftp daemon mode normal
-logins are not supported, and it must be used
-on a port other than the normal
-.Tn TELNET
-port.
-.It Fl D Ar debugmode
-This option may be used for debugging purposes.
-This allows
-.Nm telnetd
-to print out debugging information
-to the connection, allowing the user to see what
-.Nm telnetd
-is doing.
-There are several possible values for
-.Ar debugmode:
-.Bl -tag -width exercise
-.It Cm options
-Prints information about the negotiation of
-.Tn TELNET
-options.
-.It Cm report
-Prints the
-.Cm options
-information, plus some additional information
-about what processing is going on.
-.It Cm netdata
-Displays the data stream received by
-.Nm telnetd.
-.It Cm ptydata
-Displays data written to the pty.
-.It Cm exercise
-Has not been implemented yet.
-.El
-.It Fl debug
-Enables debugging on each socket created by
-.Nm telnetd
-(see
-.Dv SO_DEBUG
-in
-.Xr socket 2 ) .
-.It Fl edebug
-If
-.Nm telnetd
-has been compiled with support for data encryption, then the
-.Fl edebug
-option may be used to enable encryption debugging code.
-.It Fl P Ar loginprog
-Specifies an alternate
-.Xr login 1
-command to run to complete the login. The alternate command must
-understand the same command arguments as the standard login.
-.It Fl h
-Disables the printing of host-specific information before
-login has been completed.
-.It Fl I Ar initid
-This option is only applicable to
-.Tn UNICOS
-systems prior to 7.0.
-It specifies the
-.Dv ID
-from
-.Pa /etc/inittab
-to use when init starts login sessions. The default
-.Dv ID
-is
-.Dv fe.
-.It Fl k
-This option is only useful if
-.Nm telnetd
-has been compiled with both linemode and kludge linemode
-support. If the
-.Fl k
-option is specified, then if the remote client does not
-support the
-.Dv LINEMODE
-option, then
-.Nm telnetd
-will operate in character at a time mode.
-It will still support kludge linemode, but will only
-go into kludge linemode if the remote client requests
-it.
-(This is done by by the client sending
-.Dv DONT SUPPRESS-GO-AHEAD
-and
-.Dv DONT ECHO . )
-The
-.Fl k
-option is most useful when there are remote clients
-that do not support kludge linemode, but pass the heuristic
-(if they respond with
-.Dv WILL TIMING-MARK
-in response to a
-.Dv DO TIMING-MARK)
-for kludge linemode support.
-.It Fl l
-Specifies line mode. Tries to force clients to use line-
-at-a-time mode.
-If the
-.Dv LINEMODE
-option is not supported, it will go
-into kludge linemode.
-.It Fl n
-Disable
-.Dv TCP
-keep-alives. Normally
-.Nm telnetd
-enables the
-.Tn TCP
-keep-alive mechanism to probe connections that
-have been idle for some period of time to determine
-if the client is still there, so that idle connections
-from machines that have crashed or can no longer
-be reached may be cleaned up.
-.It Fl r Ar lowpty-highpty
-This option is only enabled when
-.Nm telnetd
-is compiled for
-.Dv UNICOS.
-It specifies an inclusive range of pseudo-terminal devices to
-use. If the system has sysconf variable
-.Dv _SC_CRAY_NPTY
-configured, the default pty search range is 0 to
-.Dv _SC_CRAY_NPTY;
-otherwise, the default range is 0 to 128. Either
-.Ar lowpty
-or
-.Ar highpty
-may be omitted to allow changing
-either end of the search range. If
-.Ar lowpty
-is omitted, the - character is still required so that
-.Nm telnetd
-can differentiate
-.Ar highpty
-from
-.Ar lowpty .
-.It Fl s
-This option is only enabled if
-.Nm telnetd
-is compiled with support for
-.Tn SecurID
-cards.
-It causes the
-.Fl s
-option to be passed on to
-.Xr login 1 ,
-and thus is only useful if
-.Xr login 1
-supports the
-.Fl s
-flag to indicate that only
-.Tn SecurID
-validated logins are allowed, and is
-usually useful for controlling remote logins
-from outside of a firewall.
-.It Fl S Ar tos
-.It Fl u Ar len
-This option is used to specify the size of the field
-in the
-.Dv utmp
-structure that holds the remote host name.
-If the resolved host name is longer than
-.Ar len ,
-the dotted decimal value will be used instead.
-This allows hosts with very long host names that
-overflow this field to still be uniquely identified.
-Specifying
-.Fl u0
-indicates that only dotted decimal addresses
-should be put into the
-.Pa utmp
-file.
-.ne 1i
-.It Fl U
-This option causes
-.Nm telnetd
-to refuse connections from addresses that
-cannot be mapped back into a symbolic name
-via the
-.Xr gethostbyaddr 3
-routine.
-.It Fl X Ar authtype
-This option is only valid if
-.Nm telnetd
-has been built with support for the authentication option.
-It disables the use of
-.Ar authtype
-authentication, and
-can be used to temporarily disable
-a specific authentication type without having to recompile
-.Nm telnetd .
-.El
-.Pp
-.Nm Telnetd
-operates by allocating a pseudo-terminal device (see
-.Xr pty 4 )
-for a client, then creating a login process which has
-the slave side of the pseudo-terminal as
-.Dv stdin ,
-.Dv stdout
-and
-.Dv stderr .
-.Nm Telnetd
-manipulates the master side of the pseudo-terminal,
-implementing the
-.Tn TELNET
-protocol and passing characters
-between the remote client and the login process.
-.Pp
-When a
-.Tn TELNET
-session is started up,
-.Nm telnetd
-sends
-.Tn TELNET
-options to the client side indicating
-a willingness to do the
-following
-.Tn TELNET
-options, which are described in more detail below:
-.Bd -literal -offset indent
-DO AUTHENTICATION
-WILL ENCRYPT
-DO TERMINAL TYPE
-DO TSPEED
-DO XDISPLOC
-DO NEW-ENVIRON
-DO ENVIRON
-WILL SUPPRESS GO AHEAD
-DO ECHO
-DO LINEMODE
-DO NAWS
-WILL STATUS
-DO LFLOW
-DO TIMING-MARK
-.Ed
-.Pp
-The pseudo-terminal allocated to the client is configured
-to operate in \*(lqcooked\*(rq mode, and with
-.Dv XTABS and
-.Dv CRMOD
-enabled (see
-.Xr tty 4 ) .
-.Pp
-.Nm Telnetd
-has support for enabling locally the following
-.Tn TELNET
-options:
-.Bl -tag -width "DO AUTHENTICATION"
-.It "WILL ECHO"
-When the
-.Dv LINEMODE
-option is enabled, a
-.Dv WILL ECHO
-or
-.Dv WONT ECHO
-will be sent to the client to indicate the
-current state of terminal echoing.
-When terminal echo is not desired, a
-.Dv WILL ECHO
-is sent to indicate that
-.Tn telnetd
-will take care of echoing any data that needs to be
-echoed to the terminal, and then nothing is echoed.
-When terminal echo is desired, a
-.Dv WONT ECHO
-is sent to indicate that
-.Tn telnetd
-will not be doing any terminal echoing, so the
-client should do any terminal echoing that is needed.
-.It "WILL BINARY"
-Indicates that the client is willing to send a
-8 bits of data, rather than the normal 7 bits
-of the Network Virtual Terminal.
-.It "WILL SGA"
-Indicates that it will not be sending
-.Dv IAC GA,
-go ahead, commands.
-.It "WILL STATUS"
-Indicates a willingness to send the client, upon
-request, of the current status of all
-.Tn TELNET
-options.
-.It "WILL TIMING-MARK"
-Whenever a
-.Dv DO TIMING-MARK
-command is received, it is always responded
-to with a
-.Dv WILL TIMING-MARK
-.ne 1i
-.It "WILL LOGOUT"
-When a
-.Dv DO LOGOUT
-is received, a
-.Dv WILL LOGOUT
-is sent in response, and the
-.Tn TELNET
-session is shut down.
-.It "WILL ENCRYPT"
-Only sent if
-.Nm telnetd
-is compiled with support for data encryption, and
-indicates a willingness to decrypt
-the data stream.
-.El
-.Pp
-.Nm Telnetd
-has support for enabling remotely the following
-.Tn TELNET
-options:
-.Bl -tag -width "DO AUTHENTICATION"
-.It "DO BINARY"
-Sent to indicate that
-.Tn telnetd
-is willing to receive an 8 bit data stream.
-.It "DO LFLOW"
-Requests that the client handle flow control
-characters remotely.
-.It "DO ECHO"
-This is not really supported, but is sent to identify a 4.2BSD
-.Xr telnet 1
-client, which will improperly respond with
-.Dv WILL ECHO.
-If a
-.Dv WILL ECHO
-is received, a
-.Dv DONT ECHO
-will be sent in response.
-.It "DO TERMINAL-TYPE"
-Indicates a desire to be able to request the
-name of the type of terminal that is attached
-to the client side of the connection.
-.It "DO SGA"
-Indicates that it does not need to receive
-.Dv IAC GA,
-the go ahead command.
-.It "DO NAWS"
-Requests that the client inform the server when
-the window (display) size changes.
-.It "DO TERMINAL-SPEED"
-Indicates a desire to be able to request information
-about the speed of the serial line to which
-the client is attached.
-.It "DO XDISPLOC"
-Indicates a desire to be able to request the name
-of the X windows display that is associated with
-the telnet client.
-.It "DO NEW-ENVIRON"

-Only sent if
-.Nm telnetd
-is compiled with support for linemode, and
-requests that the client do line by line processing.
-.It "DO TIMING-MARK"
-Only sent if
-.Nm telnetd
-is compiled with support for both linemode and
-kludge linemode, and the client responded with
-.Dv WONT LINEMODE.
-If the client responds with
-.Dv WILL TM,
-the it is assumed that the client supports
-kludge linemode.
-Note that the
-.Op Fl k
-option can be used to disable this.
-.It "DO AUTHENTICATION"
-Only sent if
-.Nm telnetd
-is compiled with support for authentication, and
-indicates a willingness to receive authentication
-information for automatic login.
-.It "DO ENCRYPT"

- * localstat
- *
- * This function handles all management of linemode.
- *
- * Linemode allows the client to do the local editing of data
- * and send only complete lines to the server. Linemode state is
- * based on the state of the pty driver. If the pty is set for
- * external processing, then we can use linemode. Further, if we
- * can use real linemode, then we can look at the edit control bits
- * in the pty to determine what editing the client should do.
- *
- * Linemode support uses the following state flags to keep track of
- * current and desired linemode state.
- * alwayslinemode : true if -l was specified on the telnetd
- * command line. It means to have linemode on as much as
- * possible.
- *
- * lmodetype: signifies whether the client can
- * handle real linemode, or if use of kludgeomatic linemode
- * is preferred. It will be set to one of the following:
- * REAL_LINEMODE : use linemode option
- * NO_KLUDGE : don't initiate kludge linemode.
- * KLUDGE_LINEMODE : use kludge linemode
- * NO_LINEMODE : client is ignorant of linemode
- *
- * linemode, uselinemode : linemode is true if linemode
- * is currently on, uselinemode is the state that we wish
- * to be in. If another function wishes to turn linemode
- * on or off, it sets or clears uselinemode.
- *
- * editmode, useeditmode : like linemode/uselinemode, but
- * these contain the edit mode states (edit and trapsig).
- *
- * The state variables correspond to some of the state information
- * in the pty.
- * linemode:
- * In real linemode, this corresponds to whether the pty
- * expects external processing of incoming data.
- * In kludge linemode, this more closely corresponds to the
- * whether normal processing is on or not. (ICANON in
- * system V, or COOKED mode in BSD.)
- * If the -l option was specified (alwayslinemode), then
- * an attempt is made to force external processing on at
- * all times.
- *
- * The following heuristics are applied to determine linemode
- * handling within the server.
- * 1) Early on in starting up the server, an attempt is made
- * to negotiate the linemode option. If this succeeds
- * then lmodetype is set to REAL_LINEMODE and all linemode
- * processing occurs in the context of the linemode option.
- * 2) If the attempt to negotiate the linemode option failed,
- * and the "-k" (don't initiate kludge linemode) isn't set,
- * then we try to use kludge linemode. We test for this
- * capability by sending "do Timing Mark". If a positive
- * response comes back, then we assume that the client
- * understands kludge linemode (ech!) and the
- * lmodetype flag is set to KLUDGE_LINEMODE.
- * 3) Otherwise, linemode is not supported at all and
- * lmodetype remains set to NO_LINEMODE (which happens
- * to be 0 for convenience).
- * 4) At any time a command arrives that implies a higher
- * state of linemode support in the client, we move to that
- * linemode support.
- *
- * A short explanation of kludge linemode is in order here.
- * 1) The heuristic to determine support for kludge linemode
- * is to send a do timing mark. We assume that a client
- * that supports timing marks also supports kludge linemode.
- * A risky proposition at best.
- * 2) Further negotiation of linemode is done by changing the
- * the server's state regarding SGA. If server will SGA,
- * then linemode is off, if server won't SGA, then linemode
- * is on.

-
-Februrary 22, 1991:
-
- Features:
-
- This version of telnet/telnetd has support for both
- the AUTHENTICATION and ENCRYPTION options. The
- AUTHENTICATION option is fairly well defined, and
- an option number has been assigned to it. The
- ENCRYPTION option is still in a state of flux; an
- option number has NOT been assigned to it yet.
- The code is provided in this release for experimental
- and testing purposes.
-
- The telnet "send" command can now be used to send
- do/dont/will/wont commands, with any telnet option
- name. The rules for when do/dont/will/wont are sent
- are still followed, so just because the user requests
- that one of these be sent doesn't mean that it will
- be sent...
-
- The telnet "getstatus" command no longer requires
- that option printing be enabled to see the response
- to the "DO STATUS" command.
-
- A -n flag has been added to telnetd to disable
- keepalives.
-
- A new telnet command, "auth" has been added (if
- AUTHENTICATE is defined). It has four sub-commands,
- "status", "debug", "disable", "enable" and "help".
-
- A new telnet command, "encrypt" has been added (if
- ENCRYPT is defined). It has many sub-commands:
- "enable", "type", "start", "stop", "input",
- "-input", "output", "-output", "status", "auto",
- "verbose", "debug", and "help".
-
- An "rlogin" interface has been added. If the program
- is named "rlogin", or the "-r" flag is given, then
- an rlogin type of interface will be used.
- ~. Terminates the session
- ~<susp> Suspend the session
- ~^] Escape to telnet command mode
- ~~ Pass through the ~.
- BUG: If you type the rlogin escape character
- in the middle of a line while in rlogin
- mode, you cannot erase it or any characters
- before it. Hopefully this can be fixed
- in a future release...
-
- General changes:
-
- A "libtelnet.a" has now been created. This libraray
- contains code that is common to both telnet and
- telnetd. This is also where library routines that
- are needed, but are not in the standard C library,
- are placed.
-
- The makefiles have been re-done. All of the site
- specific configuration information has now been put
- into a single "Config.generic" file, in the top level
- directory. Changing this one file will take care of
- all three subdirectories. Also, to add a new/local
- definition, a "Config.local" file may be created
- at the top level; if that file exists, the subdirectories
- will use that file instead of "Config.generic".
-
- Many 1-2 line functions in commands.c have been
- removed, and just inserted in-line, or replaced
- with a macro.
-
- Bug Fixes:
-
- The non-termio code in both telnet and telnetd was
- setting/clearing CTLECH in the sg_flags word. This
- was incorrect, and has been changed to set/clear the
- LCTLECH bit in the local mode word.
-
- The SRCRT #define has been removed. If IP_OPTIONS
- and IPPROTO_IP are defined on the system, then the
- source route code is automatically enabled.
-
- The NO_GETTYTAB #define has been removed; there
- is a compatability routine that can be built into
- libtelnet to achive the same results.
-
- The server, telnetd, has been switched to use getopt()
- for parsing the argument list.
-
- The code for getting the input/output speeds via
- cfgetispeed()/cfgetospeed() was still not quite
- right in telnet. Posix says if the ispeed is 0,
- then it is really equal to the ospeed.
-
- The suboption processing code in telnet now has
- explicit checks to make sure that we received
- the entire suboption (telnetd was already doing this).
-
- The telnet code for processing the terminal type
- could cause a core dump if an existing connection
- was closed, and a new connection opened without
- exiting telnet.
-
- Telnetd was doing a TCSADRAIN when setting the new
- terminal settings; This is not good, because it means
- that the tcsetattr() will hang waiting for output to
- drain, and telnetd is the only one that will drain
- the output... The fix is to use TCSANOW which does
- not wait.
-
- Telnetd was improperly setting/clearing the ISTRIP
- flag in the c_lflag field, it should be using the
- c_iflag field.
-
- When the child process of telnetd was opening the
- slave side of the pty, it was re-setting the EXTPROC
- bit too early, and some of the other initialization
- code was wiping it out. This would cause telnetd
- to go out of linemode and into single character mode.
-
- One instance of leaving linemode in telnetd forgot
- to send a WILL ECHO to the client, the net result
- would be that the user would see double character
- echo.
-
- If the MODE was being changed several times very
- quickly, telnetd could get out of sync with the
- state changes and the returning acks; and wind up
- being left in the wrong state.
-
-September 14, 1990:
-
- Switch the client to use getopt() for parsing the
- argument list. The 4.3Reno getopt.c is included for
- systems that don't have getopt().
-
- Use the posix _POSIX_VDISABLE value for what value
- to use when disabling special characters. If this
- is undefined, it defaults to 0x3ff.
-
- For non-termio systems, TIOCSETP was being used to
- change the state of the terminal. This causes the
- input queue to be flushed, which we don't want. This
- is now changed to TIOCSETN.
-
- Take out the "#ifdef notdef" around the code in the
- server that generates a "sync" when the pty oputput
- is flushed. The potential problem is that some older
- telnet clients may go into an infinate loop when they
- receive a "sync", if so, the server can be compiled
- with "NO_URGENT" defined.
-
- Fix the client where it was setting/clearing the OPOST
- bit in the c_lflag field, not the c_oflag field.
-
- Fix the client where it was setting/clearing the ISTRIP
- bit in the c_lflag field, not the c_iflag field. (On
- 4.3Reno, this is the ECHOPRT bit in the c_lflag field.)
- The client also had its interpretation of WILL BINARY
- and DO BINARY reversed.
-
- Fix a bug in client that would cause a core dump when
- attempting to remove the last environment variable.
-
- In the client, there were a few places were switch()
- was being passed a character, and if it was a negative
- value, it could get sign extended, and not match
- the 8 bit case statements. The fix is to and the
- switch value with 0xff.
-
- Add a couple more printoption() calls in the client, I
- don't think there are any more places were a telnet
- command can be received and not printed out when
- "options" is on.
-
- A new flag has been added to the client, "-a". Currently,
- this just causes the USER name to be sent across, in
- the future this may be used to signify that automatic
- authentication is requested.
-
- The USER variable is now only sent by the client if
- the "-a" or "-l user" options are explicity used, or
- if the user explicitly asks for the "USER" environment
- variable to be exported. In the server, if it receives
- the "USER" environment variable, it won't print out the
- banner message, so that only "Password:" will be printed.
- This makes the symantics more like rlogin, and should be
- more familiar to the user. (People are not used to
- getting a banner message, and then getting just a
- "Password:" prompt.)
-
- Re-vamp the code for starting up the child login
- process. The code was getting ugly, and it was
- hard to tell what was really going on. What we
- do now is after the fork(), in the child:
- 1) make sure we have no controlling tty
- 2) open and initialize the tty
- 3) do a setsid()/setpgrp()
- 4) makes the tty our controlling tty.
- On some systems, #2 makes the tty our controlling
- tty, and #4 is a no-op. The parent process does
- a gets rid of any controlling tty after the child
- is fork()ed.
-
- Use the strdup() library routine in telnet, instead
- of the local savestr() routine. If you don't have
- strdup(), you need to define NO_STRDUP.
-
- Add support for ^T (SIGINFO/VSTATUS), found in the
- 4.3Reno distribution. This maps to the AYT character.
- You need a 4-line bugfix in the kernel to get this
- to work properly:
-
- > *** tty_pty.c.ORG Tue Sep 11 09:41:53 1990
- > --- tty_pty.c Tue Sep 11 17:48:03 1990
- > ***************
- > *** 609,613 ****

- > ! if ((*(unsigned int *)data == SIGINFO) &&
- > ! ((tp->t_lflag&NOKERNINFO) == 0))
- > ! ttyinfo(tp);
- > return(0);
- > }
-
- The client is now smarter when setting the telnet escape
- character; it only sets it to one of VEOL and VEOL2 if
- one of them is undefined, and the other one is not already
- defined to the telnet escape character.
-
- Handle TERMIOS systems that have seperate input and output
- line speed settings imbedded in the flags.
-
- Many other minor bug fixes.
-
-June 20, 1990:
- Re-organize makefiles and source tree. The telnet/Source
- directory is now gone, and all the source that was in
- telnet/Source is now just in the telnet directory.
-
- Seperate makefile for each system are now gone. There
- are two makefiles, Makefile and Makefile.generic.
- The "Makefile" has the definitions for the various
- system, and "Makefile.generic" does all the work.
- There is a variable called "WHAT" that is used to
- specify what to make. For example, in the telnet
- directory, you might say:
- make 4.4bsd WHAT=clean
- to clean out the directory.
-
- Add support for the ENVIRON and XDISPLOC options.
- In order for the server to work, login has to have
- the "-p" option to preserve environment variables.
-
- Add the SOFT_TAB and LIT_ECHO modes in the LINEMODE support.
-
- Add the "-l user" option to command line and open command
- (This is passed through the ENVIRON option).
-
- Add the "-e" command line option, for setting the escape
- character.
-
- Add the "-D", diagnostic, option to the server. This allows
- the server to print out debug information, which is very
- useful when trying to debug a telnet that doesn't have any
- debugging ability.
-
- Turn off the literal next character when not in LINEMODE.
-
- Don't recognize ^Y locally, just pass it through.
-
- Make minor modifications for Sun4.0 and Sun4.1
-
- Add support for both FORW1 and FORW2 characters. The
- telnet escpape character is set to whichever of the
- two is not being used. If both are in use, the escape
- character is not set, so when in linemode the user will
- have to follow the escape character with a <CR> or <EOF)
- to get it passed through.
-
- Commands can now be put in single and double quotes, and
- a backslash is now an escape character. This is needed
- for allowing arbitrary strings to be assigned to environment
- variables.
-
- Switch telnetd to use macros like telnet for keeping
- track of the state of all the options.
-
- Fix telnetd's processing of options so that we always do
- the right processing of the LINEMODE option, regardless
- of who initiates the request to turn it on. Also, make
- sure that if the other side went "WILL ECHO" in response
- to our "DO ECHO", that we send a "DONT ECHO" to get the
- option turned back off!
-
- Fix the TERMIOS setting of the terminal speed to handle both
- BSD's seperate fields, and the SYSV method of CBAUD bits.
-
- Change how we deal with the other side refusing to enable
- an option. The sequence used to be: send DO option; receive
- WONT option; send DONT option. Now, the sequence is: send
- DO option; receive WONT option. Both should be valid
- according to the spec, but there has been at least one
- client implementation of telnet identified that can get
- really confused by this. (The exact sequence, from a trace
- on the server side, is (numbers are number of responses that
- we expect to get after that line...):
-
- send WILL ECHO 1 (initial request)
- send WONT ECHO 2 (server is changing state)
- recv DO ECHO 1 (first reply, ok. expect DONT ECHO next)
- send WILL ECHO 2 (server changes state again)
- recv DONT ECHO 1 (second reply, ok. expect DO ECHO next)
- recv DONT ECHO 0 (third reply, wrong answer. got DONT!!!)
- *** send WONT ECHO (send WONT to acknowledge the DONT)
- send WILL ECHO 1 (ask again to enable option)
- recv DO ECHO 0
-
- recv DONT ECHO 0
- send WONT ECHO 1
- recv DONT ECHO 0
- recv DO ECHO 1
- send WILL ECHO 0
- (and the last 5 lines loop forever)
-
- The line with the "***" is last of the WILL/DONT/WONT sequence.
- The change to the server to not generate that makes this same
- example become:
-
- send will ECHO 1
- send wont ECHO 2
- recv do ECHO 1
- send will ECHO 2
- recv dont ECHO 1
- recv dont ECHO 0
- recv do ECHO 1
- send will ECHO 0
-
- There is other option negotiation going on, and not sending
- the third part changes some of the timings, but this specific
- example no longer gets stuck in a loop. The "telnet.state"
- file has been modified to reflect this change to the algorithm.
-
- A bunch of miscellaneous bug fixes and changes to make
- lint happier.
-
- This version of telnet also has some KERBEROS stuff in
- it. This has not been tested, it uses an un-authorized
- telnet option number, and uses an out-of-date version
- of the (still being defined) AUTHENTICATION option.
- There is no support for this code, do not enable it.
-
-
-March 1, 1990:
-CHANGES/BUGFIXES SINCE LAST RELEASE:
- Some support for IP TOS has been added. Requires that the
- kernel support the IP_TOS socket option (currently this
- is only in UNICOS 6.0).
-
- Both telnet and telnetd now use the cc_t typedef. typedefs are
- included for systems that don't have it (in termios.h).
-
- SLC_SUSP was not supported properly before. It is now.
-
- IAC EOF was not translated properly in telnetd for SYSV_TERMIO
- when not in linemode. It now saves a copy of the VEOF character,
- so that when ICANON is turned off and we can't trust it anymore
- (because it is now the VMIN character) we use the saved value.
-
- There were two missing "break" commands in the linemode
- processing code in telnetd.
-
- Telnetd wasn't setting the kernel window size information
- properly. It was using the rows for both rows and columns...

-README: You are reading it.
-
-Config.generic:
- This file contains all the OS specific definitions. It
- has pre-definitions for many common system types, and is
- in standard makefile fromat. See the comments at the top
- of the file for more information.
-
-Config.local:
- This is not part of the distribution, but if this file exists,
- it is used instead of "Config.generic". This allows site
- specific configuration without having to modify the distributed
- "Config.generic" file.
-
-kern.diff:
- This file contains the diffs for the changes needed for the
- kernel to support LINEMODE is the server. These changes are
- for a 4.3BSD system. You may need to make some changes for
- your particular system.
-
- There is a new bit in the terminal state word, TS_EXTPROC.
- When this bit is set, several aspects of the terminal driver
- are disabled. Input line editing, character echo, and
- mapping of signals are all disabled. This allows the telnetd
- to turn of these functions when in linemode, but still keep
- track of what state the user wants the terminal to be in.
-
- New ioctl()s:
-
- TIOCEXT Turn on/off the TS_EXTPROC bit
- TIOCGSTATE Get t_state of tty to look at TS_EXTPROC bit
- TIOCSIG Generate a signal to processes in the
- current process group of the pty.
-
- There is a new mode for packet driver, the TIOCPKT_IOCTL bit.
- When packet mode is turned on in the pty, and the TS_EXTPROC
- bit is set, then whenever the state of the pty is changed, the
- next read on the master side of the pty will have the TIOCPKT_IOCTL
- bit set, and the data will contain the following:
- struct xx {
- struct sgttyb a;
- struct tchars b;
- struct ltchars c;
- int t_state;
- int t_flags;
- }
- This allows the process on the server side of the pty to know
- when the state of the terminal has changed, and what the new
- state is.
-
- However, if you define USE_TERMIO or SYSV_TERMIO, the code will
- expect that the structure returned in the TIOCPKT_IOCTL is
- the termio/termios structure.
-
-stty.diff:
- This file contains the changes needed for the stty(1) program
- to report on the current status of the TS_EXTPROC bit. It also
- allows the user to turn on/off the TS_EXTPROC bit. This is useful
- because it allows the user to say "stty -extproc", and the
- LINEMODE option will be automatically disabled, and saying "stty
- extproc" will re-enable the LINEMODE option.
-
-telnet.state:
- Both the client and server have code in them to deal
- with option negotiation loops. The algorithm that is
- used is described in this file.
-
-tmac.doc:
- Macros for use in formatting the man pages on non-4.3Reno
- systems.
-
-telnet:
- This directory contains the client code. No kernel changes are
- needed to use this code.
-
-telnetd:
- This directory contains the server code. If LINEMODE or KLUDGELINEMODE
- are defined, then the kernel modifications listed above are needed.
-
-libtelnet:
- This directory contains code that is common to both the client
- and the server.
-
-arpa:
- This directory has a new <arpa/telnet.h>
-
-
-The following TELNET options are supported:
-
- LINEMODE:
- The LINEMODE option is supported as per RFC1116. The
- FORWARDMASK option is not currently supported.
-
- BINARY: The client has the ability to turn on/off the BINARY
- option in each direction. Turning on BINARY from
- server to client causes the LITOUT bit to get set in
- the terminal driver on both ends, turning on BINARY
- from the client to the server causes the PASS8 bit
- to get set in the terminal driver on both ends.
-
- TERMINAL-TYPE:
- This is supported as per RFC1091. On the server side,
- when a terminal type is received, termcap/terminfo
- is consulted to determine if it is a known terminal
- type. It keeps requesting terminal types until it
- gets one that it recongnizes, or hits the end of the
- list. The server side looks up the entry in the
- termcap/terminfo data base, and generates a list of
- names which it then passes one at a time to each
- request for a terminal type, duplicating the last
- entry in the list before cycling back to the beginning.
-
- NAWS: The Negotiate about Window Size, as per RFC 1073.
-
- TERMINAL-SPEED:
- Implemented as per RFC 1079
-
- TOGGLE-FLOW-CONTROL:
- Implemented as per RFC 1080
-
- TIMING-MARK:
- As per RFC 860
-
- SGA: As per RFC 858
-
- ECHO: As per RFC 857
-
- STATUS:
- The server will send its current status upon
- request. It does not ask for the clients status.
- The client will request the servers current status
- from the "send getstatus" command.
-
- ENVIRON:
- This option is currently being defined by the IETF
- Telnet Working Group, and an RFC has not yet been
- issued, but should be in the near future...
-
- X-DISPLAY-LOCATION:
- This functionality can be done through the ENVIRON
- option, it is added here for completeness.
-
- AUTHENTICATION:
- This option is currently being defined by the IETF
- Telnet Working Group, and an RFC has not yet been
- issued. The basic framework is pretty much decided,
- but the definitions for the specific authentication
- schemes is still in a state of flux.
-
- ENCRYPT:
- This option is currently being defined by the IETF
- Telnet Working Group, and an RFC has not yet been
- issued. The draft RFC is still in a state of flux,
- so this code may change in the future.

-.Sh NAME
-.Nm telnet
-.Nd user interface to the
-.Tn TELNET
-protocol
-.Sh SYNOPSIS
-.Nm telnet
-.Op Fl 8EFKLacdfrx
-.Op Fl S Ar tos
-.Op Fl X Ar authtype
-.Op Fl e Ar escapechar
-.Op Fl k Ar realm
-.Op Fl l Ar user
-.Op Fl n Ar tracefile
-.Oo
-.Ar host
-.Op port
-.Oc
-.Sh DESCRIPTION
-The
-.Nm telnet
-command
-is used to communicate with another host using the
-.Tn TELNET
-protocol.
-If
-.Nm telnet
-is invoked without the
-.Ar host
-argument, it enters command mode,
-indicated by its prompt
-.Pq Nm telnet\&> .
-In this mode, it accepts and executes the commands listed below.
-If it is invoked with arguments, it performs an
-.Ic open
-command with those arguments.
-.Pp
-Options:
-.Bl -tag -width indent
-.It Fl 8
-Specifies an 8-bit data path. This causes an attempt to
-negotiate the
-.Dv TELNET BINARY
-option on both input and output.
-.It Fl E
-Stops any character from being recognized as an escape character.
-.It Fl F
-If Kerberos V5 authentication is being used, the
-.Fl F
-option allows the local credentials to be forwarded
-to the remote system, including any credentials that
-have already been forwarded into the local environment.
-.It Fl K
-Specifies no automatic login to the remote system.
-.It Fl L
-Specifies an 8-bit data path on output. This causes the
-BINARY option to be negotiated on output.
-.It Fl S Ar tos
-Sets the IP type-of-service (TOS) option for the telnet
-connection to the value
-.Ar tos,
-which can be a numeric TOS value
-or, on systems that support it, a symbolic
-TOS name found in the /etc/iptos file.
-.It Fl X Ar atype
-Disables the
-.Ar atype
-type of authentication.
-.It Fl a
-Attempt automatic login.
-Currently, this sends the user name via the
-.Ev USER
-variable
-of the
-.Ev ENVIRON
-option if supported by the remote system.
-The name used is that of the current user as returned by
-.Xr getlogin 2
-if it agrees with the current user ID,
-otherwise it is the name associated with the user ID.
-.It Fl c
-Disables the reading of the user's
-.Pa \&.telnetrc
-file. (See the
-.Ic toggle skiprc
-command on this man page.)
-.It Fl d
-Sets the initial value of the
-.Ic debug
-toggle to
-.Dv TRUE
-.It Fl e Ar escape char
-Sets the initial
-.Nm
-.Nm telnet
-escape character to
-.Ar escape char.
-If
-.Ar escape char
-is omitted, then
-there will be no escape character.
-.It Fl f
-If Kerberos V5 authentication is being used, the
-.Fl f
-option allows the local credentials to be forwarded to the remote system.
-.ne 1i
-.It Fl k Ar realm
-If Kerberos authentication is being used, the
-.Fl k
-option requests that telnet obtain tickets for the remote host in
-realm realm instead of the remote host's realm, as determined
-by
-.Xr krb_realmofhost 3 .
-.It Fl l Ar user
-When connecting to the remote system, if the remote system
-understands the
-.Ev ENVIRON
-option, then
-.Ar user
-will be sent to the remote system as the value for the variable USER.
-This option implies the
-.Fl a
-option.
-This option may also be used with the
-.Ic open
-command.
-.It Fl n Ar tracefile
-Opens
-.Ar tracefile
-for recording trace information.
-See the
-.Ic set tracefile
-command below.
-.It Fl r
-Specifies a user interface similar to
-.Xr rlogin 1 .
-In this
-mode, the escape character is set to the tilde (~) character,
-unless modified by the -e option.
-.It Fl x
-Turns on encryption of the data stream if possible. This
-option is not available outside of the United States and
-Canada.
-.It Ar host
-Indicates the official name, an alias, or the Internet address
-of a remote host.
-.It Ar port
-Indicates a port number (address of an application). If a number is
-not specified, the default

-port is used.
-.El
-.Pp
-When in rlogin mode, a line of the form ~. disconnects from the
-remote host; ~ is the telnet escape character.
-Similarly, the line ~^Z suspends the telnet session.
-The line ~^] escapes to the normal telnet escape prompt.
-.Pp
-Once a connection has been opened,
-.Nm telnet
-will attempt to enable the
-.Dv TELNET LINEMODE
-option.
-If this fails, then
-.Nm telnet
-will revert to one of two input modes:
-either \*(Lqcharacter at a time\*(Rq
-or \*(Lqold line by line\*(Rq
-depending on what the remote system supports.
-.Pp
-When
-.Dv LINEMODE
-is enabled, character processing is done on the
-local system, under the control of the remote system. When input
-editing or character echoing is to be disabled, the remote system
-will relay that information. The remote system will also relay
-changes to any special characters that happen on the remote
-system, so that they can take effect on the local system.
-.Pp
-In \*(Lqcharacter at a time\*(Rq mode, most
-text typed is immediately sent to the remote host for processing.
-.Pp
-In \*(Lqold line by line\*(Rq mode, all text is echoed locally,
-and (normally) only completed lines are sent to the remote host.
-The \*(Lqlocal echo character\*(Rq (initially \*(Lq^E\*(Rq) may be used
-to turn off and on the local echo
-(this would mostly be used to enter passwords
-without the password being echoed).
-.Pp
-If the
-.Dv LINEMODE
-option is enabled, or if the
-.Ic localchars
-toggle is
-.Dv TRUE
-(the default for \*(Lqold line by line\*(Lq; see below),
-the user's
-.Ic quit ,
-.Ic intr ,
-and
-.Ic flush
-characters are trapped locally, and sent as
-.Tn TELNET
-protocol sequences to the remote side.
-If
-.Dv LINEMODE
-has ever been enabled, then the user's
-.Ic susp
-and
-.Ic eof
-are also sent as
-.Tn TELNET
-protocol sequences,
-and
-.Ic quit
-is sent as a
-.Dv TELNET ABORT
-instead of
-.Dv BREAK
-There are options (see
-.Ic toggle
-.Ic autoflush
-and
-.Ic toggle
-.Ic autosynch
-below)
-which cause this action to flush subsequent output to the terminal
-(until the remote host acknowledges the

-(in the case of
-.Ic quit
-and
-.Ic intr ) .
-.Pp
-While connected to a remote host,
-.Nm telnet
-command mode may be entered by typing the
-.Nm telnet
