+.Nm IPXrouted
+.Nd IPX Routing Information Protocol daemon
+.Sh SYNOPSIS
+.Nm
+.Op Fl N
+.Op Fl q
+.Op Fl s
+.Op Fl S
+.Op Fl t
+.Op Ar logfile
+.Sh DESCRIPTION
+.Nm
+is invoked at boot time to manage the IPX routing tables.
+The IPX routing daemon uses the Novell IPX Routing
+Information Protocol in maintaining up to date kernel routing
+table entries.
+.Pp
+Available options:
+.Bl -tag -width logfile
+.It Fl N
+Do not reply on GetNearestServer SAP request.
+.It Fl q
+Do not supply routing information (opposite of
+.Fl s
+option below).
+.It Fl s
+Forces
+.Nm
+to supply routing information whether it is acting as an internetwork
+router or not.
+.It Fl S
+Do not supply Service Advertizing Protocol
+(SAP)
+information.
+The default is to supply
+SAP
+information.
+.It Fl t
+All packets sent or received are
+printed on the standard output.  In addition,
+.Nm
+will not divorce itself from the controlling terminal
+so that interrupts from the keyboard will kill the process.
+.It Ar logfile
+Name of file in which
+.Nm Ns 's
+actions should be logged.  This log contains information
+about any changes to the routing tables and a history of
+recent messages sent and received which are related to
+the changed route.
+.El
+.Pp
+In normal operation
+.Nm
+listens
+for routing information packets.  If the host is connected to
+multiple IPX networks, it periodically supplies copies
+of its routing tables to any directly connected hosts
+and networks.
+.Pp
+When
+.Nm
+is started, it uses the
+.Dv SIOCGIFCONF
+.Xr ioctl 2
+to find those
+directly connected interfaces configured into the
+system and marked
+.Dq up
+(the software loopback interface
+is ignored).  If multiple interfaces
+are present, it is assumed the host will forward packets
+between networks.
+.Nm
+then transmits a
+.Em request
+packet on each interface (using a broadcast packet if
+the interface supports it) and enters a loop, listening
+for
+.Em request
+and
+.Em response
+packets from other hosts.
+.Pp
+When a
+.Em request
+packet is received,
+.Nm
+formulates a reply based on the information maintained in its
+internal tables.  The
+.Em response
+packet generated contains a list of known routes, each marked
+with a
+.Dq hop count
+metric (a count of 16, or greater, is
+considered
+.Dq infinite ) .
+The metric associated with each
+route returned provides a metric
+.Em relative to the sender .
+.Pp
+.Em Response
+packets received by
+.Nm
+are used to update the routing tables if one of the following
+conditions is satisfied:
+.Bl -bullet
+.It
+No routing table entry exists for the destination network
+or host, and the metric indicates the destination is ``reachable''
+(i.e. the hop count is not infinite).
+.It
+The source host of the packet is the same as the router in the
+existing routing table entry.  That is, updated information is
+being received from the very internetwork router through which
+packets for the destination are being routed.
+.It
+The existing entry in the routing table has not been updated for
+some time (defined to be 90 seconds) and the route is at least
+as cost effective as the current route.
+.It
+The new route describes a shorter route to the destination than
+the one currently stored in the routing tables; the metric of
+the new route is compared against the one stored in the table
+to decide this.
+.El
+.Pp
+When an update is applied,
+.Nm
+records the change in its internal tables and generates a
+.Em response
+packet to all directly connected hosts and networks.
+.Xr Routed 8
+waits a short period
+of time (no more than 30 seconds) before modifying the kernel's
+routing tables to allow possible unstable situations to settle.
+.Pp
+In addition to processing incoming packets,
+.Nm
+also periodically checks the routing table entries.
+If an entry has not been updated for 3 minutes, the entry's metric
+is set to infinity and marked for deletion.  Deletions are delayed
+an additional 60 seconds to insure the invalidation is propagated
+to other routers.
+.Pp
+Hosts acting as internetwork routers gratuitously supply their
+routing tables every 30 seconds to all directly connected hosts
+and networks.
+.Pp
+If
+.Nm
+receives a SIGINFO signal the current contents of the RIP and SAP
+tables are appended to the file /var/log/ipxrouted.dmp.

+.Nd connect time accounting
+.Sh SYNOPSIS
+.Nm
+.Op Fl dp
+.\".Op Fl c Ar console
+.Op Fl t Ar tty
+.Op Fl w Ar wtmp
+.Op Ar users ...
+.Sh DESCRIPTION
+If the file
+.Pa /var/log/wtmp
+exists, a record of individual login and logout
+times are written to it by
+.Xr login 1
+and
+.Xr init 8 ,
+respectively.
+.Nm \&Ac
+examines these records and writes the accumulated connect time (in hours)
+for all logins to the standard output.
+.Pp
+The options are as follows:
+.Bl -tag -width indentXXX
+.It Fl d
+Display the connect times in 24 hour chunks.
+.\" .It Fl c Ar console
+.\" Use
+.\" .Ar console
+.\" as the name of the device that local X sessions (ut_host of ":0.0")
+.\" originate from.  If any login has been recorded on
+.\" .Ar console
+.\" then these X sessions are ignored unless COMPAT_SUNOS was defined at
+.\" compile time.
+.It Fl p
+Print individual users' totals.
+.It Fl t Ar tty
+Only do accounting logins on certain ttys.  The
+.Ar tty
+specification can start with '!' to indicate not this
+.Ar tty
+and end with '*' to indicate all similarly named ttys.
+Multiple
+.Fl t
+flags may be specified.
+.It Fl w Ar wtmp
+Read connect time data from
+.Ar wtmp
+instead of the default file,
+.Pa /var/log/wtmp .
+.It Ar users ...
+Display totals for the given individuals only.
+.El
+.Pp
+If no arguments are given,
+.Nm
+displays the total connect time for all
+accounts with login sessions recorded in
+.Pa wtmp .
+.Pp
+The default
+.Pa wtmp
+file will increase without bound unless it is truncated.
+It is normally truncated by the daily scripts run
+by
+.Xr cron 8 ,
+which rename and rotate the
+.Pa wtmp
+files, keeping a week's worth of data on
+hand.  No login or connect time accounting is performed if
+.Pa /var/log/wtmp
+does not exist.
+.Pp
+For example,
+.Bd -literal -offset
+ac -p -t "ttyd*" > modems
+ac -p -t "!ttyd*" > other
+.Ed
+.Pp
+allows times recorded in
+.Pa modems
+to be charged out at a different rate than
+.Pa other .
+.Sh DIAGNOSTICS
+.Ex -std
+.Sh FILES
+.Bl -tag -width /var/log/wtmp -compact
+.It Pa /var/log/wtmp
+connect time accounting file
+.El
+.Sh SEE ALSO
+.Xr login 1 ,
+.Xr utmp 5 ,
+.Xr init 8 ,
+.Xr sa 8
+.\" .Sh NOTES
+.\" If COMPAT_SUNOS is defined
+.\" .Nm ac
+.\" ignores the fact that entries with ut_host of ":0.0" are not real
+.\" login sessions.  Normally such entries are ignored except in the case
+.\" of a user being logged in when the
+.\" .Pa wtmp
+.\" file was rotated, in which case a login with ut_host of ":0.0" may
+.\" appear without any preceding console logins.
+.\" If no one is logged in on the console, the user is deemed to have
+.\" logged in on at the earliest time stamp found in
+.\" .Pa wtmp .
+.\" Use of
+.\" .Pa console
+.\" allows
+.\" .Nm ac
+.\" to identify and correctly process a logout for the user.  The default
+.\" value for
+.\" .Pa console
+.\" is usually correct at compile time.

+.Sh NAME
+.Nm acpidump
+.Nd dump ACPI tables
+.Sh SYNOPSIS
+.Nm
+.Op Fl r
+.Nm
+.Op Fl r
+.Op Fl o Ar dsdt_file_for_output
+.Nm
+.Op Fl r
+.Op Fl f Ar dsdt_file_for_input
+.Sh DESCRIPTION
+The
+.Nm
+command analyzes ACPI tables in physical memory and dumps them to standard output.
+In addition,
+.Nm
+can disassemble AML
+(ACPI Machine Language)
+found in these tables and dump them as ASL
+(ACPI Source Language).
+.Pp
+ACPI tables have an essential data block (the DSDT,
+Differentiated System Description Table),
+that includes information used on the kernel side such as
+detailed information about PnP hardware, procedures for controlling
+power management support and so on.
+.Nm
+can extract the DSDT data block from physical memory and store it into
+a DSDT data file, and also can generate an output in ASL
+from a given DSDT data file.
+.Pp
+When
+.Nm
+is invoked without the
+.Fl f
+option, it will read ACPI tables from physical
+memory via a special file
+.Pa /dev/mem
+and dump them.
+First it searches for the RSDP
+(Root System Description Pointer),
+which has the signature
+.Qq RSD PTR\ \& ,
+and then gets the RSDT
+(Root System Description Table),
+which includes a list of pointers to physical memory addresses
+for other tables.
+The RSDT itself and all other tables linked from RSDT are generically
+called SDTs
+(System Description Tables)
+and their header has a common format which consists of items
+such as Signature, Length, Revision, Checksum, OEMID, OEM Table ID,
+OEM Revision, Creator ID and Creator Revision.
+.Nm
+dumps contents of these SDTs.
+For further information about formats of each table,
+see chapter 5:
+.Dq ACPI Software Programming Model
+from the ACPI specifications referenced below.
+.Pp
+There is always a pointer to a physical memory address in RSDT for FACP
+(Fixed ACPI Description Table).
+The FACP defines static system information about power management support
+(ACPI Hardware Register Implementation)
+such as interrupt mode
+(INT_MODEL),
+SCI interrupt number, SMI command port
+(SMI_CMD)
+and location of ACPI registers.
+The FACP also has a pointer to a physical memory address for DSDT,
+which includes information used on the kernel side such as
+PnP, power management support and so on.
+While the other tables are described in fixed format,
+the DSDT consists of AML data which is compiled from sources
+written in free formated ASL, which is the description language for ACPI.
+When
+.Nm
+outputs DSDT, it disassembles the AML data and
+formats it as ASL.
+.Sh OPTIONS
+The following options are supported by
+.Nm :
+.Bl -tag -width indent
+.It Fl o Ar dsdt_file_for_output
+Stores DSDT data block from physical memory into a file specified in
+.Ar dsdt_file_for_output
+in addition to behavior with no option.
+.It Fl f Ar dsdt_file_for_input
+Interprets AML data in DSDT from a file specified in
+.Ar dsdt_file_for_input
+and dumps them in ASL to standard output.
+.It Fl r
+Additionally outputs commented ResourceTemplate() macros for Buffer
+objects that contain valid resource streams.
+These macros are defined in the ACPI 2.0 specification section
+16.2.4.
+.It Fl h
+Displays usage and exit.
+.El
+.Sh EXAMPLES
+This is an example to get a dump of SDTs and a DSDT data file
+simultaneously on a machine that supports ACPI BIOS.
+.Bd -literal -offset indent

+.Nd executing and debugging AML interpreter
+(with DSDT files)
+.Sh SYNOPSIS
+.Nm
+.Op Fl dhst
+.Ar dsdt_file ...
+.Sh DESCRIPTION
+.Nm Amldb
+parses the DSDT
+(Differentiated System Description Table)
+files, which usually are acquired from ACPI BIOS, and executes
+the sequence of ACPI Control Methods described in AML
+(ACPI Machine Language)
+with its AML interpreter.
+.Nm Amldb
+also has a simple ACPI virtual machine.  During execution of the
+Control Methods each access to the region, such as
+SystemMemory, SystemIO, PCI_Config, does not affect the real
+hardware but only the virtual machine.
+Because the sequence of virtual accesses is maintained in user space,
+AML interpreter developers need not worry about any effect on hardware
+when they analyze DSDT data files.  They can develop and debug the
+interpreter, even if the machine has no ACPI BIOS.
+.Pp
+The developer will need to acquire a DSDT data file from any machine
+with ACPI BIOS through
+.Xr acpidump 8 .
+The DSDT is a table, a part of the whole ACPI memory table
+located in somewhere in the BIOS area
+.Pq Li 0xa0000 \- 0x100000 .
+It includes such information as the detailed hardware information
+for PnP, and the set of procedures which perform power management from
+the OS.  The information is stored in AML format.
+.Pp
+The AML interpreter can execute any of the Control Methods specified
+by users.  When executed, it interprets the byte sequence in the
+Control Method of DSDT, and disassembles the opecodes that it
+recognizes into ASL
+(ACPI Source Language)
+format to be displayed.
+.Pp
+If it encounters one of more accesses to the region such as
+SystemMemory in executing the Control Methods, its ACPI Virtual
+Machine simulates the input/output operations to the resources in the
+region.  In writing to a certain region, the ACPI Virtual Machine
+prepares a piece of memory corresponding to its address,
+if necessary, and holds the specified value in the memory as the
+.Em region contents .
+In reading from a certain region, it fetches the value in the memory
+.Pq Em region contents ,
+prompts with it as the following:
+.Bd -literal -offset indent
+DEBUG[read(0, 0x100b6813)&mask:0x1](default: 0x1 / 1) >>
+.Ed
+.Pp
+for users to have the opportunity to modify it, and hands it to
+the AML interpreter.  In case that there is no corresponding region
+in the AML Virtual Machine, the value zero is handed.
+.Pp
+The interpreter continues to maintain all of the
+.Em region contents
+until
+.Nm
+terminates.  You can specify their initial values with the file
+.Pa region.ini
+in the current directory.  If it is executed with
+.Fl d
+option, it dumps the final status of all of its
+.Em region contents
+to the file
+.Pa region.dmp
+when it terminates.  Each line of there files consists of the following
+fields, separated by tabs; region type, address, and value.
+Region types are specified as follows;
+.TS H
+box;
+c | l.
+value	region type
+=
+0	SystemMemory
+1	SystemIO
+2	PCI_Concig
+3	EmbeddedControl
+4	SMBus
+.TE
+.Pp
+Interactive commands are described below:
+.Bl -tag -width indent
+.It Cm s
+.Em Single step :
+Performs single-step execution of the current Control Method.  If
+the next instruction is an invocation of another Control Method,
+the step execution will continue in the following Control Method.
+.It Cm n
+.Em Step program :
+Performs single-step execution of the current Control Method.
+Even if the next instruction is an invocation of another Control
+Method, the step execution will not continue.
+.It Cm c
+.Em Continue program being debugged :
+Resumes execution of the AML interpreter.  Because the current
+.Nm
+has no way of breakpoint, this command might not so much useful.
+.It Cm q
+.Em Quit method execution :
+Terminates execution of the current Control Method.  If
+.Nm
+is not in execution, this command causes to input the next
+DSDT data file.  If there are no next DSDT data files, it
+terminates
+.Nm
+itself.
+.It Cm t
+.Em Show local name space tree and variables :
+Displays the structure of the ACPI namespace tree.  If
+.Nm
+is in execution, this command displays the structure that relates
+to the objects, arguments, and local variables below the scope of the
+current Control Method.
+.It Cm i
+.Em Toggle region input prompt :
+Switches whether the prompt for modifying the value read from the
+.Em region contents
+be showed or not.  Default is On.
+.It Cm o
+.Em Toggle region output prompt :
+Switches whether the prompt for modifying the value to be written
+to the region contents will be shown or not.  The default is Off.
+.It Cm m
+.Em Show memory management statistics :
+Displays the current statistics of the memory management system
+on the AML interpreter.
+.It Cm r Ar method
+.Em Run specified method :
+Executes the specified Control Method.  If it requires one or
+more arguments, a prompt such as the following appears;
+.Bd -literal
+Method: Arg 1 From 0x280626ce To 0x28062775
+  Enter argument values (ex. number 1 / string foo). 'q' to quit.
+  Arg0 ?
+.Ed
+.Pp
+For each argument, a pair of type string and value delimited by
+one or more spaces can be entered.  Now only
+.Ic number
+and
+.Ic string
+can be specified as the type string.
+In the current implementation, only the first character of the type
+string, such as
+.Ic n
+or
+.Ic s ,
+is identified.  For example, we can enter as follows:
+.Bd -literal
+  Arg0 ? n 1
+.Ed
+.Pp
+.It Cm f Ar string
+.Em Find named objects from namespace :
+Lists the named objects that includes the specified string as the
+terminate elements searching from the ACPI namespace.  For the
+namespace is expressed as the sequence of four-character elements,
+appropriate number of additional underscore
+.Pq Ql _
+characters are necessary for specifying objects which have less than four
+character string.  Unless additional underscores specified, matching
+occurs as the beginning of word with the specified number of characters.
+.It Cm h
+.Em Show help messsage :
+Displays the command summary of
+.Nm .
+.El
+.Sh OPTIONS
+Exactly one of the following options must be specified.  Otherwise,
+.Nm
+shows its usage and terminates.
+.Bl -tag -width indent
+.It Fl d
+Dump the final status of all of the
+.Em region contents
+in the ACPI Virtual Machine to the file
+.Pa region.dmp .
+.It Fl h
+Terminate with the usage of this command.
+.It Fl s
+Display the statistics of the memory management system on the
+AML interpreter when
+.Nm
+terminates.
+.It Fl t
+Display the tree structure of ACPI namespace after the
+DSDT data file is read.
+.El
+.Sh EXAMPLES
+The following is an example including, invoking the
+.Nm ,
+searching
+.Li _PRS
+(Possible Resource Settings)
+objects, and executing the
+.Li _PTS
+(Prepare To Sleep)
+Control Method by the AML interpreter.

+.Sh BUGS
+The ACPI virtual machine does not completely simulate the behavior
+of a machine with an ACPI BIOS.  In the current implementation, the
+ACPI virtual machine only reads or writes the stored values by
+emulating access to regions such as SystemMemory.
+.Pp
+Because the AML interpreter interprets and disassembles
+simultaneously, it is impossible to implement such features as setting
+breakpoints with the specified line number in ASL.  Setting breakpoints
+at certain Control Methods, which is not very difficult, has not
+yet implemented because nobody has ever needed it.

+.Sh DESCRIPTION
+.Nm Adduser
+is a simple program for adding new users.
+Adduser checks
+the passwd, group and shell databases.
+It creates passwd/group entries,
+.Ev HOME
+directory, dotfiles and sends the new user a welcome message.
+.Sh RESTRICTIONS
+.Bl -tag -width Ds -compact
+.It Sy username
+Login name.
+May contain only lowercase characters or digits.
+Maximum length
+is 16 characters (see
+.Xr setlogin 2
+BUGS section).
+The reasons for this limit are "Historical".
+Given that people have traditionally wanted to break this
+limit for aesthetic reasons, it's never been of great importance to break
+such a basic fundamental parameter in UNIX.
+You can change
+.Dv UT_NAMESIZE
+in
+.Pa /usr/include/utmp.h
+and recompile the
+world; people have done this and it works, but you will have problems
+with any precompiled programs, or source that assumes the 8-character
+name limit and NIS.
+The NIS protocol mandates an 8-character username.
+If you need a longer login name for e-mail addresses,
+you can define an alias in
+.Pa /etc/mail/aliases .
+.It Sy fullname
+Firstname and surname.
+The
+.Ql Pa \&:
+character is not allowed.
+.It Sy shell
+Only valid shells from the shell database or sliplogin and pppd
+.It Sy uid
+Automatically generated or your choice, must be less than 32000.
+.It Sy gid/login group
+Your choice or automatically generated.
+.It Sy password
+If not empty, password is encoded with
+.Xr crypt 3 .
+.El
+.Sh UNIQUE GROUPS
+Perhaps you're missing what
+.Em can
+be done with this scheme that falls apart
+with most other schemes.  With each user in his/her own group the user can
+safely run with a umask of 002 and have files created in their home directory
+and not worry about others being able to read them.
+.Pp
+For a shared area you create a separate uid/gid (like cvs or ncvs on freefall),
+you place each person that should be able to access this area into that new
+group.
+.Pp
+This model of uid/gid administration allows far greater flexibility than lumping
+users into groups and having to muck with the umask when working in a shared
+area.
+.Pp
+I have been using this model for almost 10 years and found that it works
+for most situations, and has never gotten in the way.  (Rod Grimes)
+.Sh CONFIGURATION
+.Bl -enum
+.It
+Read internal variables.
+.It
+Read configuration file (/etc/adduser.conf).
+.It
+Parse command line options.
+.El
+.Sh OPTIONS
+.Bl -tag -width Ds
+.It Fl check_only
+Check /etc/passwd, /etc/group, /etc/shells and exit.
+.It Fl class Ar login_class
+Set default login class.
+.It Fl config_create
+Create new configuration and message file and exit.
+.It Fl dotdir Ar directory
+Copy files from
+.Ar directory
+into the
+.Ev HOME
+directory of new users,
+.Ql Pa dot.foo
+will be renamed to
+.Ql Pa .foo .
+Don't copy files if
+.Ar directory
+specified is equal to
+.Ar no .
+For security make all files writable and readable for owner,
+don't allow group or world to write files and allow only owner
+to read/execute/write
+.Pa .rhost ,
+.Pa .Xauthority ,
+.Pa .kermrc ,
+.Pa .netrc ,
+.Pa Mail ,
+.Pa prv ,
+.Pa iscreen ,
+.Pa term .
+.It Fl group Ar login_group
+Login group.
+.Ar USER
+means that the username is to be used as login group.
+.It Fl help , h , \&?
+Print a summary of options and exit.
+.It Fl home Ar partition
+Default home partition where all users located.
+.It Fl message Ar file
+Send new users a welcome message from
+.Ar file .
+Specifying a value of
+.Ar no
+for
+.Ar file
+causes no message to be sent to new users.
+.It Fl noconfig
+Do not read the default configuration file.
+.It Fl shell Ar shell
+Default shell for new users.
+.It Fl silent , s , quiet , q
+Few warnings, questions, bug reports.
+.It Fl uid Ar uid

+.Dt RMUSER 8
+.Os
+.Sh NAME
+.Nm rmuser
+.Nd removes users from the system
+.Sh SYNOPSIS
+.Nm
+.Op Fl y
+.Op Ar username
+.Sh DESCRIPTION
+The utility
+.Nm
+.Pp
+.Bl -enum
+.It
+Removes the user's
+.Xr crontab 1
+entry (if any).
+.It
+Removes any
+.Xr at 1
+jobs belonging to the user.
+.It
+Sends a SIGKILL signal to all processes owned by the user.
+.It
+Removes the user from the system's local password file.
+.It
+Removes the user's home directory (if it is owned by the user),
+including handling of symbolic links in the path to the actual home
+directory.
+.It
+Removes the incoming mail and pop daemon mail files belonging to the
+user from
+.Pa /var/mail .
+.It
+Removes all files owned by the user from
+.Pa /tmp ,
+.Pa /var/tmp ,
+and
+.Pa /var/tmp/vi.recover .
+.It
+Removes the username from all groups to which it belongs in
+.Pa /etc/group .
+(If a group becomes empty and the group name is the same as the username,
+the group is removed; this complements
+.Xr adduser 8 Ns 's
+per-user unique groups).
+.El
+.Pp
+.Nm Rmuser
+politely refuses to remove users whose uid is 0 (typically root), since
+certain actions (namely, killing all the user's processes, and perhaps
+removing the user's home directory) would cause damage to a running system.
+If it is necessary to remove a user whose uid is 0, see
+.Xr vipw 8
+for information on directly editing the password file, by which the desired
+user's
+.Xr passwd 5
+entry may be removed manually.
+.Pp
+If not running "affirmatively" (i.e., option
+.Fl y
+is not specified),
+.Nm
+shows the selected user's password file entry and asks for confirmation
+that you wish to remove the user.  If the user's home directory is owned
+by the user,
+.Nm
+asks whether you wish to remove the user's home directory and everything
+below.
+.Pp
+As
+.Nm
+operates, it informs the user regarding the current activity.  If any
+errors occur, they are posted to standard error and, if it is possible for
+.Nm
+to continue, it will.
+.Pp
+Available options:
+.Pp
+.Bl -tag -width username
+.It Fl y
+Affirm - any question that would be asked is answered implicitly in
+the affirmative (i.e., yes).  A username must also be specified on the
+command line if this option is used.
+.It Ar \&username
+Identifies the user to be removed; if not present,
+.Nm
+interactively asks for the user to be removed.
+.El
+.Sh FILES
+.Bl -tag -width /etc/master.passwd -compact
+.It Pa /etc/master.passwd
+.It Pa /etc/passwd
+.It Pa /etc/group
+.It Pa /etc/spwd.db

+.Sh HISTORY
+The
+.Nm
+command appeared in
+.Fx 2.2 .
+.\" .Sh AUTHOR
+.\" Guy Helmer, Ames, Iowa
+.Sh BUGS
+.Nm Rmuser
+does not comprehensively search the filesystem for all files
+owned by the removed user and remove them; to do so on a system
+of any size is prohibitively slow and I/O intensive.
+.Nm Rmuser
+also is unable to remove symbolic links that were created by the
+user in
+.Pa /tmp
+or
+.Pa /var/tmp
+as symbolic links on
+.Bx 4.4
+filesystems do not contain information
+as to who created them.  Also, there may be other files created in
+.Pa /var/mail
+other than
+.Pa /var/mail/username
+and
+.Pa /var/mail/.pop.username
+that are not owned by the removed user but should be removed.
+.Pp
+.Nm Rmuser
+has no knowledge of NIS (Yellow Pages), and it operates only on the
+local password file.

+.Sh DESCRIPTION
+The
+.Nm
+command controls the operation of Aironet wireless networking
+devices via the
+.Xr an 4
+driver.
+Most of the parameters that can be changed relate to the
+IEEE 802.11 protocol which the Aironet cards implement.
+This includes such things as
+the station name, whether the station is operating in ad-hoc (point
+to point) or infrastructure mode, and the network name of a service
+set to join.
+The
+.Nm
+command can also be used to view the current NIC status, configuration
+and to dump out the values of the card's statistics counters.
+.Pp
+The
+.Ar iface
+argument given to
+.Nm
+should be the logical interface name associated with the Aironet
+device
+.Li ( an0 , an1 ,
+etc.).
+If one isn't specified the device
+.Dq Li an0
+will be assumed.
+.Pp
+The
+.Nm
+command is not designed to support the combination of arguments from different
+.Sx SYNOPSIS
+lines in a single
+.Nm
+invocation, and such combinations are not recommended.
+.Sh OPTIONS
+The options are as follows:
+.Bl -tag -width indent
+.It Fl i Ar iface Fl A
+Display the preferred access point list.
+The AP list can be used by
+stations to specify the MAC address of access points with which it
+wishes to associate.
+If no AP list is specified (the default) then
+the station will associate with the first access point that it finds
+which serves the SSID(s) specified in the SSID list.
+The AP list can
+be modified with the
+.Fl a
+option.
+.It Fl i Ar iface Fl N
+Display the SSID list.
+This is a list of service set IDs (i.e., network names)
+with which the station wishes to associate.
+There may be up to three SSIDs
+in the list: the station will go through the list in ascending order and
+associate with the first matching SSID that it finds.
+.It Fl i Ar iface Fl S
+Display NIC status information.
+This includes the current operating
+status, current BSSID, SSID, channel, beacon period and currently
+associated access point.
+The operating mode indicates the state of
+the NIC, MAC status and receiver status.
+When the
+.Qq Li synced
+keyword
+appears, it means the NIC has successfully associated with an access
+point, associated with an ad-hoc
+.Dq master
+station, or become a
+.Dq master
+itself.
+The beacon period can be anything between 20 and 976 milliseconds.
+The default is 100.
+.It Fl i Ar iface Fl I
+Display NIC capability information.
+This shows the device type,
+frequency, speed and power level capabilities and firmware revision levels.
+.It Fl i Ar iface Fl T
+Display the NIC's internal statistics counters.
+.It Fl i Ar iface Fl C
+Display current NIC configuration.
+This shows the current operation mode,
+receive mode, MAC address, power save settings, various timing settings,
+channel selection, diversity, transmit power and transmit speed.
+.It Fl i Ar iface Fl t Cm 0 Ns - Ns Cm 4
+Select transmit speed.
+The available settings are as follows:
+.Bl -column ".Em TX rate" -offset indent
+.Em "TX rate	NIC speed"
+.It Cm 0 Ta "Auto -- NIC selects optimal speed"
+.It Cm 1 Ta "1Mbps fixed"
+.It Cm 2 Ta "2Mbps fixed"
+.It Cm 3 Ta "5.5Mbps fixed"
+.It Cm 4 Ta "11Mbps fixed"
+.El
+.Pp
+Note that the 5.5 and 11Mbps settings are only supported on the 4800
+series adapters: the 4500 series adapters have a maximum speed of 2Mbps.
+.It Fl i Ar iface Fl s Cm 0 Ns - Ns Cm 3

+.Sh SECURITY NOTES
+WEP
+.Pq Dq "wired equivalent privacy"
+is based on the RC4 algorithm,
+using a 24 bit initialization vector.
+.Pp
+RC4 is supposedly vunerable to certain known plaintext attacks,
+especially with 40 bit keys.
+So the security of WEP in part depends on how much known plaintext
+is transmitted.
+.Pp
+Because of this, although counter-intuitive, using
+.Dq "shared key"
+authentication (which involves sending known plaintext) is less
+secure than using
+.Dq open
+authentication when WEP is enabled.
+.Pp
+Devices may alternate among all of the configured WEP keys when
+tranmitting packets.
+Therefore, all configured keys (up to four) must agree.

+.Sh HISTORY
+The
+.Nm
+command first appeared in
+.Fx 4.0 .
+.Sh BUGS
+The statistics counters do not seem to show the amount of transmit
+and received frames as increasing.
+This is likely due to the fact that
+the
+.Xr an 4
+driver uses unmodified packet mode instead of letting the NIC perform
+802.11/ethernet encapsulation itself.
+.Pp
+Setting the channel does not seem to have any effect.

+.Sh NAME
+.Nm apm , zzz

+.Sh SYNOPSIS
+.Nm

+.Op Fl d Ar enable
+.Op Fl e Ar enable
+.Op Fl h Ar enable
+.Op Fl r Ar delta
+.Pp
+.Nm zzz
+.Sh DESCRIPTION
+.Nm Apm
+controls the Intel / Microsoft APM (Advanced Power Management) BIOS and
+displays the current status of APM on laptop PCs.
+.Nm Zzz
+suspends the system by controlling APM.
+.Pp
+The following options are available for
+.Nm
+(no options are available for
+.Nm zzz ) .
+If no options are specified,
+.Nm
+displays information and current status of APM in verbose mode.
+If multiple display options are given, the values are displayed one
+per line in the order given here.
+.Bl -tag -width indent
+.It Fl a
+Display the current AC-line status as an integer value.  The values
+0 and 1 correspond to the
+.Dq off-line
+state or
+.Dq on-line
+state, respectively.
+.It Fl b
+Display an integer value reflecting the current battery status.
+The values 0, 1, 2, 3, correspond to the
+.Dq high
+status,
+.Dq low
+status,
+.Dq critical
+status,
+.Dq charging
+status respectively.
+.It Fl d Ar enable
+Disable/enable suspending of the display separately from a normal suspend
+using the boolean value for
+.Ar enable .
+This feature seems to not work on many different laptops,
+including the Libretto 30CT and 50CT.
+.It Fl e Ar enable
+Enable or disable APM functions of the computer,
+depending on the boolean
+.Ar enable
+argument.
+.It Fl h Ar enable
+Depending on the boolean value of
+.Ar enable ,
+enable or disable the HLT instruction in the kernel context switch routine.
+These options are not necessary for almost all APM implementations,
+but for some implementations whose
+.Dq Pa Idle CPU
+call executes both CPU clock slowdown and HLT instruction,
+.Fl t
+is necessary to prevent the system from reducing its peak performance.
+See
+.Xr apm 4
+for details.
+.It Fl l
+Display the remaining battery percentage.  If your laptop does not
+support this function, 255 is displayed.
+.It Fl r Ar delta
+Enable the resume wakeup timer, if the laptop supports it.  This
+doesn't actually suspend the laptop, but if the laptop is suspended,
+and it supports resume from suspend, then it will be resumed after
+.Ar delta
+seconds (from when you run this command, not from when you suspend).
+.It Fl s
+Display the status of the APM support as an integer value.  The values
+0 and 1 correspond to the
+.Dq disabled
+state or
+.Dq enabled
+state respectively.
+.It Fl t
+Display the estimated remaining battery lifetime in seconds.  If
+it is unknown, -1 is displayed.
+.It Fl Z
+Transition the system into standby mode.  This mode uses less power than
+full power mode, but more than suspend mode.  Some laptops support
+resuming from this state on timer or Ring Indicator events.  The
+output of apm tells what your laptop claims to support.
+.It Fl z
+Suspend the system.
+It is equivalent to
+.Nm zzz .
+.El
+.Sh BUGS
+Some APM implementations do not support parameters needed by
+.Nm .
+On such systems,
+.Nm
+displays them as unknown.
+.Pp
+Some APM implementations cannot handle events such as pushing the
+power button or closing the cover.  On such implementations, the system
+.Ar must
+be suspended
+.Ar only
+by using
+.Nm
+or
+.Nm zzz .
+.Sh NOTES
+.Xr apmconf 8
+has been merged in
+.Xr apm 8
+and thus
+.Xr apm 8
+replaces all of its functionality.

+FreeBSD apmd Package Release Notes (19990711 version)
+
+1. What is "apmd"?
+==================
+
+The apmd package provides a means of handling various APM events from
+userland code.  Using apmd.conf, the apmd(8) configuration file, you
+can select the APM events to be handled from userland and specify the
+commands for a given event, allowing APM behaviour to be configured
+flexibly.
+
+
+2. How to install the apmd package
+==================================
+
+2.1 Making the apmd control device file
+---------------------------------------
+
+apmd(8) uses the new special device file /dev/apmctl.  This should be
+created as follows:
+
+# cd /dev
+# mknod apmctl c 39 8
+
+2.2 Applying the kernel patch and building a new kernel
+-------------------------------------------------------
+
+The next step is to apply the patch against the sys source tree.
+Go to the source directory (eg. /usr/src/ or /usr/PAO3/src/) and run
+the patch command as follows:
+
+# gzip -cd [somewhere]/apmd-sys-R320.diff | patch
+
+For PAO3 users, the patch file name would be apmd-sys-PAO3.diff
+instead of apmd-sys-R320.diff.  After this step has completed
+successfully, build and install a new kernel and reboot your system.
+
+2.3 Making the apmd program
+---------------------------
+
+Go to src/usr.sbin/ and extract the apmd tarball as follows:
+
+# tar xzpvf [somewhere]/apmd-usr.sbin.tar.gz 
+
+Before doing a make all, you need to copy apm_bios.h in the sys source
+tree to /usr/include/machine/ first:
+
+# cp /sys/i386/include/apm_bios.h /usr/include/machine/
+
+Then do the build and install steps in the apmd directory:
+
+# cd src/usr.sbin/apmd
+# make depend all install
+
+2.4 Setting up the configuration file and userland script
+---------------------------------------------------------
+
+In src/usr.sbin/apm/etc/ there are example configuration and userland
+script files which are invoked automatically when the APM BIOS informs
+apmd of an event, such as suspend request.  Copy these files to
+/etc/ as follows:
+
+# cp src/usr.sbin/apm/etc/* /etc/
+
+
+3. Running the apmd daemon program
+==================================
+
+To run apmd(8) in background mode, simply type ``apmd''.
+
+# apmd
+
+To make a running apmd reload /etc/apmd.conf, send a SIGHUP signal to
+the apmd(8) process.
+
+# kill -HUP [apmd pid]
+or
+# killall -HUP apmd
+
+apmd has some command line options.  For the details, please 
+refer to the manpage of apmd.
+
+4. Configuration file
+=====================
+
+The structure of the apmd configuration file is quite simple.  For
+example:
+
+apm_event SUSPENDREQ {
+	exec "sync && sync && sync";
+	exec "sleep 1";
+	exec "zzz";
+}
+
+Will cause apmd to recieve the APM event SUSPENDREQ (which may be
+posted by an LCD close), run the sync command 3 times and wait for a
+while, then execute zzz (apm -z) to put the system in the suspend
+state.
+
+4.1 The apm_event keyword
+-------------------------
+`apm_event' is the keyword which indicates the start of configuration for
+each events.
+
+4.2 APM events
+--------------
+
+If you wish to execute the same commands for different events, the
+event names should be delimited by a comma.  The following are valid
+event names:
+
+o Events ignored by the kernel if apmd is running:
+
+STANDBYREQ
+SUSPENDREQ
+USERSUSPENDREQ
+BATTERYLOW
+
+o Events passed to apmd after kernel handling:
+
+NORMRESUME
+CRITRESUME
+STANDBYRESUME
+POWERSTATECHANGE
+UPDATETIME
+
+
+Other events will not be sent to apmd.
+
+4.3 command line syntax
+-----------------------
+
+In the example above, the three lines begining with `exec' are commands 
+for the event.  Each line should be terminated with a semicolon.  The
+command list for the event should be enclosed by `{' and `}'. apmd(8)
+uses /bin/sh for double-quotation enclosed command execution, just as
+with system(3).  Each command is executed in order until the end of
+the list is reached or a command finishes with a non-zero status code. 
+apmd(8) will report any failed command's status code via syslog(3)
+and will then reject the request event posted by APM BIOS.
+
+4.4 Built-in functions
+----------------------
+
+You can also specify apmd built-in functions instead of command lines.
+A built-in function name should be terminated with a semicolon, just as
+with a command line.
+The following built-in functions are currently supported:
+
+o reject;
+
+  Reject last request posted by the APM BIOS.  This can be used to reject a
+  SUSPEND request when the LCD is closed and put the system in a STANDBY
+  state instead.
+
+
+
+5. EXAMPLES
+===========
+
+Sample configuration commands include:
+
+apm_event SUSPENDREQ {
+	exec "/etc/rc.suspend";
+}
+
+apm_event USERSUSPENDREQ {
+	exec "sync && sync && sync";
+	exec "sleep 1";
+	exec "apm -z";
+}
+
+apm_event NORMRESUME, STANDBYRESUME {
+	exec "/etc/rc.resume";
+}
+
+# resume event configuration for serial mouse users by
+# reinitializing a moused(8) connected to a serial port.
+#
+#apm_event NORMRESUME {
+#	exec "kill -HUP `cat /var/run/moused.pid`";
+#}
+
+# suspend request event configuration for ATA HDD users:
+# execute standby instead of suspend.
+#
+#apm_event SUSPENDREQ {
+#	reject;
+#	exec "sync && sync && sync";
+#	exec "sleep 1";
+#	exec "apm -Z";
+#}
+
+
+6. Call for developers
+======================
+
+The initial version of apmd(8) was implemented primarily to test the
+kernel support code and was ALPHA quality.  Based on that code, the
+current version was developed by KOIE Hidetaka <hide@koie.org>. 
+However, we're still looking around for interesting new features and
+ideas, so if you have any thoughts, please let us know. 
+Documentation is also sparse, and the manpage have just written.  
+If you wish to collaborate on this work, please e-mail me:
+iwasaki@freebsd.org.

+.Nm apmd
+.Nd Advanced Power Management monitor daemon
+.Sh SYNOPSIS
+.Nm
+.Op Fl d
+.Op Fl f file
+.Op Fl v
+.Sh DESCRIPTION
+.Nm Apmd
+monitors the occurrence of the specified Advanced Power Management
+.Pq Tn APM
+events and, if one of the events occurs, it executes the sequence of
+commands corresponding to the event.  Only the events specified in the
+configuration file are notified to
+.Nm ;
+all other events are ignored.  For each event posted by the APM BIOS,
+.Nm
+invokes the sequence of commands specified in the configuration file.
+When
+.Nm
+is running with monitoring suspend/standby requests,
+the kernel will not process those requests.
+Therefore, if you wish action to be taken when these events
+occur, you need to explicitly configure the appropriate commands or
+built-in functions in the configuration file.
+.Pp
+.Nm Apmd
+recognizes the following runtime options:
+.Bl -tag -width -f_file
+.It Fl d
+Starts in debug mode.  This causes
+.Nm
+to execute in the foreground instead of in daemon mode.
+.It Fl f Ar file
+Specifies a different configuration file
+.Ar file
+to be used in place of the default
+.Pa /etc/apmd.conf .
+.It Fl v
+Verbose mode.
+.El
+.Pp
+When
+.Nm
+starts, it reads the configuration file
+.Pa ( /etc/apmd.conf
+as default)
+and notifies the set of events to be monitored to the APM device driver.
+When it terminates, the APM device driver automatically cancels
+monitored events.
+.Pp
+If the
+.Nm
+process receives a SIGHUP, it will reread its configuration file and
+notify the APM device driver of any changes to its configuration.
+.Pp
+.Nm Apmd
+uses the device
+.Pa /dev/apmctl
+to issue
+.Xr ioctl 2
+requests for monitoring events and for controlling the APM system.
+This device file is opened exclusively, so only a single
+.Nm
+process can be running at any time.
+.Pp
+When
+.Nm
+receives an APM event, it forks a child process to execute the
+commands specified in the configuration file and then continues
+listening for more events.  The child process executes the commands
+specified, one at a time and in the order that they are listed.
+.Pp
+While
+.Nm
+is processing the command list for SUSPEND/STANDBY requests, the APM kernel
+device driver issues notifications to APM BIOS once per second so that the
+BIOS knows that there are still some commands pending, and that it should not
+complete the request just yet.
+.Pp
+The
+.Nm
+daemon creates the file
+.Pa /var/run/apmd.pid ,
+and stores its process
+id there.
+This can be used to kill or reconfigure
+.Nm .
+.Sh CONFIGURATION FILE
+The structure of the
+.Nm
+configuration file is quite simple.  For example:
+.Pp
+.Bd -literal

+.Dt ARP 4
+.Os
+.Sh NAME
+.Nm arp
+.Nd Address Resolution Protocol
+.Sh SYNOPSIS
+.Cd "pseudo-device ether"
+.Sh DESCRIPTION
+The Address Resolution Protocol (ARP) is used to dynamically
+map between Protocol Addresses (such as IP addresses) and
+Local Network Addresses (such as Ethernet addresses).
+This implementation maps IP addresses to Ethernet,
+ARCnet,
+or Token Ring addresses.
+It is used by all the Ethernet interface drivers.
+.Pp
+ARP caches Internet-Ethernet address mappings.
+When an interface requests a mapping for an address not in the cache,
+ARP queues the message which requires the mapping and broadcasts
+a message on the associated network requesting the address mapping.
+If a response is provided, the new mapping is cached and any pending
+message is transmitted.
+ARP will queue at most one packet while waiting for a response to a
+mapping request;
+only the most recently ``transmitted'' packet is kept.
+If the target host does not respond after several requests,
+the host is considered to be down for a short period (normally 20 seconds),
+allowing an error to be returned to transmission attempts during this
+interval.
+The error is
+.Er EHOSTDOWN
+for a non-responding destination host, and
+.Er EHOSTUNREACH
+for a non-responding router.
+.Pp
+The ARP cache is stored in the system routing table as
+dynamically-created host routes.
+The route to a directly-attached Ethernet network is installed as a
+.Dq cloning
+route (one with the
+.Li RTF_CLONING
+flag set),
+causing routes to individual hosts on that network to be created on
+demand.
+These routes time out periodically (normally 20 minutes after validated;
+entries are not validated when not in use).
+An entry for a host which is not responding is a
+.Dq reject
+route (one with the
+.Li RTF_REJECT
+flag set).
+.Pp
+ARP entries may be added, deleted or changed with the
+.Xr arp 8
+utility.
+Manually-added entries may be temporary or permanent,
+and may be
+.Dq published ,
+in which case the system will respond to ARP requests for that host
+as if it were the target of the request.
+.Pp
+In the past,
+ARP was used to negotiate the use of a trailer encapsulation.
+This is no longer supported.
+.Pp
+ARP watches passively for hosts impersonating the local host (i.e. a host
+which responds to an ARP mapping request for the local host's address).
+.Sh DIAGNOSTICS
+.Em "arp: %x:%x:%x:%x:%x:%x is using my IP address %d.%d.%d.%d!" :
+ARP has discovered another host on the local network which responds to
+mapping requests for its own Internet address with a different Ethernet
+address, generally indicating that two hosts are attempting to use the
+same Internet address.
+.Pp
+.Em "arp: ether address is broadcast for IP address %d.%d.%d.%d!" :
+ARP requested information for a host, and received an answer indicating
+that the host's ethernet address is the ethernet broadcast address.
+This indicates a misconfigured or broken device.
+.Pp
+.Em "arp: %d.%d.%d.%d moved from %x:%x:%x:%x:%x:%x to %x:%x:%x:%x:%x:%x" :
+ARP had a cached value for the ethernet address of the referenced host,
+but received a reply indicating that the host is at a new address.  This
+can happen normally when host hardware addresses change, or when a mobile
+node arrives or leaves the local subnet.  It can also indicate a problem
+with proxy ARP.
+.Pp
+.Em "arpresolve: can't allocate llinfo for %d.%d.%d.%d" :
+The route for the referenced host points to a device upon which ARP is
+required, but ARP was unable to allocate a routing table entry in which
+to store the host's MAC address.  This usually points to a misconfigured
+routing table.  It can also occur if the kernel cannot allocate memory.

+.Nm arp
+.Nd address resolution display and control
+.Sh SYNOPSIS
+.Nm
+.Op Fl n
+.Ar hostname
+.Nm
+.Op Fl n
+.Fl a
+.Nm
+.Fl d Ar hostname
+.Op Cm pub
+.Nm
+.Fl d
+.Fl a
+.Nm
+.Fl s Ar hostname ether_addr
+.Op Cm temp
+.Op Cm pub Op Cm only
+.Nm
+.Fl S Ar hostname ether_addr
+.Op Cm temp
+.Op Cm pub Op Cm only
+.Nm
+.Fl f Ar filename
+.Sh DESCRIPTION
+The
+.Nm
+program displays and modifies the Internet-to-Ethernet address translation
+tables used by the address resolution protocol
+.Pq Xr arp 4 .
+With no flags, the program displays the current
+.Tn ARP
+entry for
+.Ar hostname .
+The host may be specified by name or by number,
+using Internet dot notation.
+.Pp
+Available options:
+.Bl -tag -width indent
+.It Fl a
+The program displays or deletes all of the current
+.Tn ARP
+entries.
+.It Fl d
+A super-user may delete an entry for the host called
+.Ar hostname
+with the
+.Fl d
+flag.
+If the
+.Cm pub
+keyword is specified, only the
+.Dq published
+.Tn ARP
+entry
+for this host will be deleted.
+.Pp
+Alternatively, the
+.Fl d
+flag may be combined with the
+.Fl a
+flag to delete all entries.
+.It Fl n
+Show network addresses as numbers (normally
+.Nm
+attempts to display addresses symbolically).
+.It Fl s Ar hostname ether_addr
+Create an
+.Tn ARP
+entry for the host called
+.Ar hostname
+with the Ethernet address
+.Ar ether_addr .
+The Ethernet address is given as six hex bytes separated by colons.
+The entry will be permanent unless the word
+.Cm temp
+is given in the command.
+If the word
+.Cm pub
+is given, the entry will be
+.Dq published ;
+i.e., this system will
+act as an
+.Tn ARP
+server,
+responding to requests for
+.Ar hostname
+even though the host address is not its own.
+In this case the
+.Ar ether_addr
+can be given as
+.Cm auto
+in which case the interfaces on this host will be examined,
+and if one of them is found to occupy the same subnet, its
+Ethernet address will be used.
+If the
+.Cm only
+keyword is also specified, this will create a
+.Dq "published (proxy only)"
+entry.
+This type of entry is created automatically if
+.Nm
+detects that a routing table entry for
+.Ar hostname
+already exists.
+.It Fl S Ar hostname ether_addr
+Is just like
+.Fl s
+except any existing
+.Tn ARP
+entry for this host will be deleted first.
+.It Fl f Ar filename
+Causes the file
+.Ar filename
+to be read and multiple entries to be set in the
+.Tn ARP
+tables.  Entries
+in the file should be of the form
+.Pp
+.Bd -ragged -offset indent -compact
+.Ar hostname ether_addr
+.Op Cm temp
+.Op Cm pub
+.Ed
+.Pp
+with argument meanings as given above.

+.Os
+.Sh NAME
+.Nm atmarpd
+.Nd "ATMARP/SCSP interface daemon"
+.Sh SYNOPSIS
+.Nm
+.Op Fl d
+.Op Fl l Aq Ar log_file
+.Aq Ar net_intf
+.Ar ...
+.Sh DESCRIPTION
+.Nm Atmarpd
+provides an interface between the ATMARP server in the
+kernel and the SCSP daemon for the Host ATM Research Platform
+(HARP) networking software.
+.Nm Atmarpd
+reads the ATMARP cache from the kernel periodically
+and passes any updated entries to
+.Xr scspd 8
+so they will be
+propagated to remote servers.
+It also accepts updated entries that remote servers have sent to
+.Xr scspd 8
+and, if they are
+new or more up to date than current entries, installs them
+in the kernel's ATMARP cache.
+Both
+.Nm
+and
+.Xr scspd 8
+must be running before any ATMARP cache synchronization can take place.
+.Pp
+When
+.Nm
+starts, it parses its command line and puts
+itself into the background.
+.Pp
+The command-line options are:
+.Bl -tag -width "-l <log_file>"
+.It Fl l Aq Ar log_file
+Specifies that
+.Nm
+is to write log messages to the
+file named
+.Aq Ar log_file
+rather than to the system log.
+.It Fl d
+Specifies that
+.Nm
+is to be run in debug mode.
+In debug mode,
+.Nm
+is not put into the background.
+Log messages are written to standard output instead of to
+the log file.
+.It Aq Ar net_intf
+Specifies the network interface(s) for which the host is providing
+ATMARP service and whose caches are to be synchronized using SCSP.
+If multiple network interface names are specified,
+.Nm
+will provide an interface to
+.Xr scspd 8
+for the servers on all the
+specified interfaces.
+.El
+.Sh SIGNAL PROCESSING
+The following signals can be used to control
+.Nm :
+.Bl -tag -width indent
+.It Dv SIGINT
+Dump debugging information to a file.
+When it receives a

+.Op Fl d
+.Op Fl T Ns Aq Ar options
+.Sh DESCRIPTION
+.Nm Scspd
+is an implementation of the Server Cache Synchronization
+Protocol (SCSP) for the Host ATM Research Platform (HARP)
+networking software.
+.Nm Scspd
+synchronizes the cache(s) of server(s)
+running on a host with the caches of servers on remote hosts.
+SCSP is defined for a number of different protocols, but the present
+version of
+.Nm
+only supports ATMARP.
+.Pp
+By using
+.Nm
+and
+.Xr atmarpd 8 ,
+one can provide multiple
+ATMARP servers in a single ATM LIS.
+This might be useful, for example, when a LIS consists of a number of
+local-area ATM networks connected by long-distance links.
+Each local-area network could have its own ATMARP server, with all the
+servers' caches being synchronized by SCSP.
+Then, if a long-distance link fails, hosts on a local-area network
+will still have connectivity to other local hosts (since they all use
+the local ATMARP server); when the long-distance link is restored,
+SCSP will re-synchronize the servers' caches, restoring
+connectivity to remote hosts.
+Both
+.Nm
+and
+.Xr atmarpd 8
+must be running before any ATMARP
+cache synchronization can take place.
+.Pp
+.Nm Scspd
+implements SCSP as specified in RFC 2334,
+.%T "Server Cache Synchronization Protocol (SCSP)"
+and
+.Pa draft\-ietf\-ion\-scspd\-atmarpd\-00.txt ,
+.%T "A Distributed ATMARP Service using SCSP" .
+.Pp
+When
+.Nm
+starts, it parses its command line and puts
+itself into the background.
+.Sh TERMINOLOGY
+Some of the vocabulary associated with SCSP can be confusing.
+In this document, the following definitions are used:
+.Pp
+.Em "Client server"
+or
+.Em "local server"
+means the server running on
+the same host as
+.Nm
+whose cache is to be synchronized with that
+of one or more remote servers.
+When the word
+.Em server
+is used alone, it means
+.Em "client server" .
+.Pp
+.Em "Remote server"
+means a server running on some host other than
+the one where
+.Nm
+is running.
+.Pp
+.Em "Directly Connected Server"
+(DCS) means a remote server that
+.Nm
+communicates with directly.
+The remote server will also be running an implementation of SCSP.
+.Pp
+.Em "Cache Alignment"
+(CA) has two meanings.
+The Cache Alignment protocol is a part of the SCSP protocol
+specification, and the Cache Alignment finite state machine (FSM)
+is a finite state machine that implements the Cache Alignment
+protocol.
+.Sh OPTIONS
+The command-line options are:
+.Bl -tag -width "-f <cfg\-file>"
+.It Fl f Aq Ar cfg\-file
+Specifies the name of the configuration file.
+If this option is not specified,
+.Nm
+looks for the
+file
+.Pa /etc/scspd.conf .
+.It Fl d
+Specifies that
+.Nm
+is to be run in debug mode.
+In debug mode, the daemon is not put into the background.
+Log messages are written to standard output instead of to
+the log file specified in the configuration file.
+.It Fl T Ns Aq Ar options
+Specifies that
+.Nm
+will trace specified events and messages
+as it executes.
+The
+.Fl T
+flag is followed by one or more of the following
+options:
+.Pp
+.Bl -tag -width 4n -compact
+.It Cm c
+trace
+.Nm Ns 's
+CA Finite State Machine (FSM),
+.It Cm h
+trace
+.Nm Ns 's
+Hello FSM,
+.It Cm i
+trace
+.Nm Ns 's
+Client Interface FSM,
+.It Cm C
+trace CA, CSUS, CSU Request, and CSU Reply messages,
+.It Cm H
+trace Hello messages,
+.It Cm I
+trace interface messages to and from
+.Nm Ns 's
+clients.
+.El
+.El
+.Sh CONFIGURATION
+The configuration file consists of a sequence of configuration
+statements.
+These statements specify information about the servers,
+both local and remote, whose
+caches are to be synchronized by
+.Nm .
+RFC 2334,
+.%T "Server Cache Synchronization Protocol (SCSP)"
+and
+.Pa draft\-ietf\-ion\-scspd\-atmarpd\-00.txt ,
+.%T "A Distributed ATMARP Service using SCSP"
+will be valuable in understanding how to configure
+.Nm .
+.Pp
+A configuration statement other than a comment is terminated by a
+semicolon.
+Some statements contain blocks, delimited by braces
+.No ( Dq Li {
+and
+.Dq Li } ) .
+Configuration statement keywords are not case-sensitive,
+but some parameters (e.g. interface names) are.
+Configuration statements can span multiple lines.
+.Ss Comments
+Three types of comments are allowed:
+.Bl -hang
+.It Sy "# comments" :
+any characters from
+.Dq Li #
+to the end of the line are ignored.
+.It Sy "C comments" :
+any characters between
+.Dq Li /*
+and
+.Dq Li */
+are ignored.
+.It Sy "C++ comments" :
+any characters from
+.Dq Li //
+to the end of the line are ignored.
+.El
+.Ss Statements
+The configuration statements recognized by
+.Nm
+are:
+.Bd -literal
+Server <name> {
+	Protocol <protocol ID>;
+	Netif <if_name>;
+	ServerGroupID <ID>;
+	FamilyID <ID>;
+	DCS {
+		ATMaddr <ATM address>;
+		ID <host>;
+		CAReXmitInt <int>;
+		CSUSReXmitInt <int>;
+		CSUReXmitInt <int>;
+		CSUReXmitMax <cnt>;
+		HelloDead <cnt>;
+		HelloInt <int>;
+		Hops <cnt>;
+	};
+};
+
+Log {
+	File <file name>;
+	Syslog;
+};
+.Ed
+.Pp
+Where a host address needs to be specified in the configuration file,
+either a DNS name or an IP address in dotted decimal format can
+be used.
+.Pp
+ATM addresses are specified as strings of hex digits, with an
+optional leading
+.Dq Li 0x .
+Fields within the address may be separated by periods, but periods
+are for readability only and are ignored.
+ATM addresses are 20 bytes long.
+The full address, including any leading zeroes, must be given.
+For example:
+.Pp
+.Dl "0x47.0005.80.ffe100.0000.f21a.0170.0020481a0170.00"
+.Ss "Server Statement"
+The
+.Ic server
+statement specifies a client server whose cache
+to be synchronized with the caches of other servers
+running on remote hosts.
+There will be one
+.Ic server
+statement in the configuration file
+for each client server whose cache is to be synchronized by
+.Nm .
+The format of the
+.Ic server
+statement is:
+.Bd -ragged -offset indent
+.Ic Server
+.Aq Ar name
+{
+.Aq Ar statements
+};
+.Ed
+.Pp
+A
+.Ar name
+must be specified on the
+.Ic server
+statement, but it is
+not used by
+.Nm .
+It is expected to give a brief description of the server's purpose.
+.Pp
+The
+.Ic server
+statement has several sub-statements
+that specify the details of the
+.Nm Ns 's
+configuration.
+They are:
+.Bl -tag -width indent
+.It Ic Protocol Cm ATMARP ;
+The only protocol supported by the current version of
+.Nm
+is
+.Cm ATMARP .
+The
+.Ic protocol
+statement must always be specified.
+.It Ic Netif Aq Ar intf ;
+The
+.Ic netif
+statement specifies the name of the ATM network
+interface on which a client server is providing service.
+The
+.Ic netif
+statement must always be specified.
+.It Ic ServerGroupID Aq Ar ID ;
+The
+.Ic ServerGroupID
+statement specifies an identifier for the
+group of servers being synchronized by
+.Nm .
+The
+.Ar ID
+is specified as a decimal number in the range 0 - 65,535.
+The server group ID must be the same for all servers whose caches
+are being synchronized by an SCSP session.
+That is, the server group ID for a host must be the same for all
+Directly Connected Servers (DCSs) pointed to within a
+.Ic server
+statement.
+The
+.Ic ServerGroupID
+statement must always be specified.
+.It Ic FamilyID Aq Ar ID ;
+The
+.Ic familyID
+statement specifies an identifier for a family
+of parallel SCSP sessions running between a group of hosts (i.e. a
+set of SCSP sessions with different protocol IDs but the same set
+of servers).
+The
+.Ar ID
+is specified as a decimal number in the range 0 - 65,535.
+The family ID is currently not used by
+.Nm .
+.El
+.Ss "DCS Statement"
+The
+.Ic DCS
+statement is a sub-statement of the
+.Ic server
+statement
+that specifies the characteristics of a Directly Connected Server (DCS).
+The
+.Ic server
+statement will have one
+.Ic DCS
+statement for
+each DCS that
+.Nm
+is to exchange information with.
+The
+.Ic DCS
+statement has a number of sub-statements that specify the
+details of the configuration for the DCS.
+They are:
+.Bl -tag -width indent
+.It Ic ATMaddr Aq Ar ATM\ address ;
+The
+.Ic ATMaddr
+statement specifies the ATM address of the DCS.
+The
+.Ic ATMaddr
+statement must always be specified.
+.It Ic ID Aq Ar host ;
+The
+.Ic ID
+statement specifies the SCSP identifier of the DCS.
+For ATMARP, the ID is the IP address or DNS name associated with the
+ATM interface of the DCS.
+The
+.Ic ID
+statement must always be specified.
+.It Ic CAReXmitInt Aq Ar int ;
+The
+.Ic CAReXmitInt
+statement specifies the interval that is
+allowed to elapse between retransmissions of CA messages.
+If a CA message is sent and an acknowledgement is not received within
+.Ic CAReXmitInt
+seconds, the message will be retransmitted.
+The default value for
+.Ic CAReXmitInt
+is 3 seconds.
+.It Ic CSUSReXmitInt Aq Ar int ;
+The
+.Ic CSUSReXmitInt
+statement specifies the interval that is
+allowed to elapse between retransmissions of CSU Solicit messages.
+When a CSUS message is sent, any Cache State Advertisements (CSAs)
+requested by the CSUS that have
+not been received within
+.Ic CSUSReXmitInt
+seconds will be requested
+again by another CSUS message.
+The default value for
+.Ic CSUSReXmitInt
+is 3 seconds.
+Be careful not to confuse
+.Ic CSUSReXmitInt
+and
+.Ic CSUReXmitInt .
+.It Ic CSUReXmitInt Aq Ar int ;
+The
+.Ic CSUReXmitInt
+statement specifies the interval that is
+allowed to elapse between retransmissions of CSU Request messages.
+When a CSU Request message is sent, any CSAs that are not acknowledged
+by a CSU Reply message within
+.Ic CSUReXmitInt
+seconds will
+be retransmitted.
+The default value for
+.Ic CSUReXmitInt
+is 2 seconds.
+Be careful not to confuse
+.Ic CSUReXmitInt
+and
+.Ic CSUSReXmitInt .
+.It Ic CSUReXmitMax Aq Ar cnt ;
+The
+.Ic CSUReXmitMax
+statement specifies the number of times that
+a CSA will be retransmitted as described above before SCSP gives up
+on the CSA and discards it.
+The default value for
+.Ic CSUReXmitMax
+is 5.
+.It Ic HelloDead Aq Ar cnt ;
+The
+.Ic HelloDead
+statement specifies the Hello Dead Factor that
+will be sent to the DCS in Hello messages.
+A
+.Dq "DCS down"
+condition will be detected when nothing is received from
+a DCS in
+.Ic HelloDead No * Ic HelloInt
+seconds.
+The default value for
+.Ic HelloDead
+is 3.
+.It Ic HelloInt Aq Ar int ;
+The
+.Ic HelloInt
+statement specifies the Hello Interval that
+will be sent to the DCS in Hello messages.
+The default value for
+.Ic HelloInt
+is 3 seconds.
+.It Ic Hops Aq Ar cnt ;
+The
+.Ic Hops
+statement specifies the number of hops (DCS to DCS)
+that will be specified in CSAs originating from the local server.
+This number must be at least as large as the diameter of the
+server group.
+That is, it must be large enough for a CSA to be propagated from
+server to server all the way across the server group.
+The default value for
+.Ic Hops
+is 3.
+.El
+.Ss "Log Statement"
+The
+.Ic log
+statement specifies how
+.Nm
+is to log
+information about its operation.
+.Nm Scspd
+can write log information to a file, to the system log,
+or both.
+.Bl -tag -width indent
+.It Ic File Aq Ar file\ name ;
+The
+.Ic file
+statement specifies that
+.Nm
+is to write
+its log messages to the named file.
+Log messages will be appended to the end of the file if
+it already exists.
+.It Ic Syslog ;
+The
+.Ic syslog
+statement specifies that
+.Nm
+is to write
+its log messages to the syslog facility.
+.Nm Scspd
+writes its messages to syslog with a facility code
+of
+.Dv LOG_DAEMON .
+.El
+.Pp
+If no
+.Ic log
+statement is specified,
+.Nm
+writes log
+messages to the system log.
+If both
+.Ic file
+and
+.Ic syslog
+are specified,
+.Nm
+will
+write log messages to both the named file and the system log.
+.Ss Examples
+An example of a simple configuration file for
+.Nm
+might be:
+.Bd -literal -offset indent
+server atmarp_ni0 {
+     protocol ATMARP;
+     netif ni0;
+     ServerGroupID 23;
+     DCS {
+          ID 10.1.1.2;
+          ATMaddr 0x47.0005.80.ffdc00.0000.0002.0001.002048061de7.00;
+          hops 2;
+     };
+};
+.Ed
+.Pp
+This configuration would synchronize the cache of the ATMARP server
+operating on network interface ni0 with the cache of a second server
+running on a host whose IP address is 10.1.1.2.
+Log messages would be written to the system log.
+.Sh SIGNAL PROCESSING
+The following signals can be used to control
+.Nm :
+.Bl -tag -width indent
+.It Dv SIGHUP
+Reread the configuration file and restart
+.Nm .
+.It Dv SIGINT
+Dump debugging information to a file.
+When it receives a
+.Dv SIGINT
+signal,
+.Nm
+dumps a summary of
+its control blocks to a text file (see
+.Sx FILES ) .
+.El
+.Sh FILES
+.Bl -tag -width indent
+.It Pa /etc/scspd.conf
+.Nm Scspd
+default configuration file name.
+A different file name can be specified with the
+.Fl f
+command-line
+option.
+.It Xo
+.Sm off
+.Pa /tmp/scspd.
+.Aq Ar pid
+.Pa \&.
+.Aq Ar seq
+.Pa .out
+.Sm on
+.Xc
+Debugging information dump file name.
+.Nm Scspd
+writes a summary of its control blocks to this file
+when it receives a
+.Dv SIGINT
+signal.
+.Aq Ar pid
+is the process ID of the daemon and
+.Aq Ar seq
+is a sequence
+number which is incremented every time a dump is taken.
+.It Xo
+.Sm off
+.Pa /tmp/scspd.
+.Aq Ar pid
+.Pa .trace
+.Sm on
+.Xc
+Trace file.
+.Nm Scspd
+writes trace information to this file if the
+.Fl T
+option is specified on the command line.

+.Sh NAME
+.Nm boot0cfg
+.Nd boot manager installation/configuration utility
+.Sh SYNOPSIS
+.Nm
+.Op Fl Bv
+.Op Fl b Ar boot0
+.Op Fl d Ar drive
+.Op Fl f Ar file
+.Op Fl m Ar mask
+.Op Fl o Ar options
+.Op Fl s Ar slice
+.Op Fl t Ar ticks
+.Ar disk
+.Sh DESCRIPTION
+The
+.Fx
+.Sq boot0
+boot manager permits the operator to select from which disk and
+slice an i386 machine (PC) is booted.
+.Pp
+Note that what are referred to here as
+.Dq slices
+are typically called
+.Dq partitions
+in
+.No non- Ns Bx
+documentation relating to the PC.
+Typically, only non-removable disks are sliced.
+.Pp
+The
+.Nm
+utility optionally installs the
+.Sq boot0
+boot manager on the specified
+.Ar disk ;
+and allows various operational parameters to be configured.
+.Pp
+On PCs, a boot manager typically occupies sector 0 of a disk, which is
+known as the Master Boot Record (MBR).
+The MBR contains both code (to which control is passed by the PC BIOS)
+and data (an embedded table of defined slices).
+.Pp
+The options are:
+.Bl -tag -width indent
+.It Fl B
+Install the
+.Sq boot0
+boot manager.
+This option causes MBR code to be replaced, without
+affecting the embedded slice table.
+.It Fl b Ar boot0
+Specify which
+.Sq boot0
+image to use.
+The default is
+.Pa /boot/boot0 .
+.It Fl d Ar drive
+Specify the drive number used by the PC BIOS in referencing the drive
+which contains the specified
+.Ar disk .
+Typically this will be 0x80 for the first hard drive, 0x81 for the
+second hard drive, and so on; however any integer between 0 and 0xff
+is acceptable here.
+.It Fl f Ar file
+Specify that a backup copy of the preexisting MBR should be written to
+.Ar file .
+This file is created if it does not exist, and replaced if it does.
+.It Fl m Ar mask
+Specify slices to be enabled/disabled, where
+.Ar mask
+is an integer between 0 (no slices enabled) and 0xf (all four slices
+enabled).
+.It Fl o Ar options
+A comma-separated string of any of the following options may be
+specified (with
+.Dq no
+prepended as necessary):
+.Bl -tag -width indent
+.It packet
+Use the disk packet (BIOS Int 0x13 extensions) interface, as
+as opposed to the legacy (CHS) interface, when doing disk I/O.
+This allows booting above cylinder 1023, but requires specific
+BIOS support.
+The default is
+.Sq nopacket .
+.It setdrv
+Forces the drive containing the disk to be referenced using drive
+number definable by means of the -d option.
+The default is
+.Sq nosetdrv .
+.It update
+Allow the MBR to be updated by the boot manager.
+(The MBR may be updated to flag slices as
+.Sq active ,
+and to save slice selection information.)
+This is the default; a
+.Sq noupdate
+option causes the MBR to be treated as read-only.
+.El
+.It Fl s Ar slice
+Set the default boot selection to
+.Ar slice .
+Values between 1 and 4 refer to slices; a value of 5 refers to the
+option of booting from a second disk.
+.It Fl t Ar ticks
+Set the timeout value to
+.Ar ticks .
+(There are approximately 18.2 ticks per second.)
+.It Fl v
+Verbose: display information about the slices defined, etc.
+.El
+.Sh FILES
+.Bl -tag -width /boot/boot0 -compact
+.It Pa /boot/boot0
+The default
+.Sq boot0
+image
+.El
+.Sh EXAMPLES
+The following is an example of a typical usage
+of the
+.Nm
+command to affect the next boot:
+.Pp
+.Dl "boot0cfg -s 2 ad0"
+.Sh DIAGNOSTICS
+.Ex -std
+.Sh SEE ALSO
+.Xr boot 8 ,
+.Xr fdisk 8
+.Sh AUTHORS
+.An Robert Nordier Aq rnordier@FreeBSD.org .
+.Sh BUGS
+Use of the
+.Sq packet
+option may cause
+.Sq boot0
+to fail, depending on the nature of BIOS support.
+.Pp
+Use of the
+.Sq setdrv
+option with an incorrect -d operand may cause the MBR to be written
+to the wrong disk.
+Be careful!

+.Sh DESCRIPTION
+On NEC PC-98s,
+.Sq boot loader
+consists of the
+.Sq IPL
+and
+.Sq HDD boot menu .
+The IPL occupies sector 0 of a disk and is followed by the partition
+table.  The IPL loads the HDD boot menu that starts from 0x400.
+.Pp
+The
+.Nm
+installs and makes backup copy of the IPL and the HDD boot menu; and
+allows changing the version number field in the sector 0.
+.Pp
+Note that the format command in NEC's OSs replaces the HDD boot menu
+with its own HDD boot menu when the version number field is smaller
+than that in the format command.
+.Pp
+The options are:
+.Bl -tag -width indent
+.It Fl B
+Install the IPL and HDD boot menu.  This option causes the IPL and HDD
+boot menu code to be replaced.
+.It Fl i Ar boot0
+Specify which IPL image to use.  The default is /boot/boot0.
+.It Fl m Ar boot0.5
+Specify which HDD boot menu image to use.  The default is
+/boot/boot0.5.
+.It Fl f Ar boot0.bak
+Specify that a backup copy of the preexisting IPL should be written to
+.Ar boot0.bak .
+This file is created if it does not exist, and truncated if it does.
+.It Fl F Ar boot0.5.bak
+Specify that a backup copy of the preexisting HDD boot menu should be
+written to
+.Ar boot0.5.bak .
+This file is created if it does not exist, and truncated if it does.
+.It Fl v Ar version
+Specify the version number.
+.It Fl s Ar secsize
+Specify the sector size.  The default sector size is 512
+(bytes/sector).

+
+This directory contains a version of the rpc.bootparamd, which have been 
+written using the Sun's RPC protocol for bootparamd. To use it you must 
+have a copy of the bootparam_prot.x file which on Sun systems you find in
+
+	/usr/include/rpcsvc/bootparam_prot.x
+
+(( This file was retrieved from the Sun-RPC source package ))
+
+
+This code is not copyright, and is placed in the public domain. Feel free to 
+use and modify. Please send modifications and/or suggestions + bug fixes to

+	Klas Heggemann <klas@nada.kth.se>
+
+
+RPC.BOOTPARAMD
+
+
+The rpc.bootparamd program does NOT use the yellow pages for the bootparams
+database. This data should recide in /etc/bootparams on the local host,
+or another file given when the server is started.
+
+The default router is set to the address of the machine running the server.
+This may not be a good thing to do, so it can be modified using the -r 
+option when startning the daemon.
+
+This program was written with the need to keep short hostnames in the
+/etc/bootparams file and long (canonical) names in the hosts database.
+It probably also will work in conjunction with a nameserver, since matching
+is done by comparing the canonical name of the booting machine with the
+canonical name of the hosts found in the bootparams database. 
+
+It is kept simple, e g there is no caching of data, but the bootparameter file
+is read at each request. 
+
+
+CALLBOOTD
+
+The debugging tool callbootd is used to check the response you get
+to a specific (booting) request. It can be used as
+	callbootd server inet-address 
+or
+	callbootd server hostname file 
+where "server" is a machine running the rpc.bootparamd program, "inet-address"
+is the internet address of a booting machine, "hostname" is the name of a
+booting machine and "file" the requested file, typically "root", "swap" or
+"dump". 
+
+You may also use "all" instead of a specific server, in which case a RPC
+broadcast is performed. The broadcast is performed 4 times and then the 
+program times out, after printing all responses. 
+
+
+TODO
+
+Cache the date, instead of rereading it. 
+Maybe match by comparing the inet address instead. (But beware that caching
+will prevent the server from detecting that a machine has changed name
+or address.)

+This version will allow the use of aliases on the hostname in the
+.Pa /etc/bootparams
+file.
+The returned hostname to the
+.Em whoami
+request done by the booting client
+will be the name that appears in
+.Pa /etc/bootparams
+and not the canonical name.
+In this way you can keep the answer short enough
+so that machines that cannot handle long hostnames will not fail during boot.
+.Sh OPTIONS
+.Bl -tag -width Fl
+.It Fl d
+Display the debugging information.
+.It Fl s
+Log the debugging information with
+.Xr syslog 3 .
+.It Fl r Ar router
+The default router (a machine or an IP-address).
+This defaults to the machine running the server.
+.It Fl f Ar file
+The file to use as boot parameter file instead of
+.Pa /etc/bootparams .

+default boot parameter file

+.Sh EXAMPLES
+When netbooting diskless SunOS/Xkernel SPARCstations the booted SunOS kernel
+also broadcasts to the all-0 address.
+The SunOS kernel hangs until it receives a reply.
+To accommodate this behaviour add an alias address
+that responds to an all-0 broadcast.
+So, add something like
+.Ql "ifconfig xl0 192.168.200.254 netmask 255.255.255.255 broadcast 192.168.200.0 alias
+on the relevant network interface on your
+.Nm
+server.
+The alias address must of course be free for use.
+.Sh SEE ALSO
+.Xr syslog 3 ,
+.Xr bootparams 5 ,
+.Xr diskless 8
+.Sh BUGS
+You may find the
+.Xr syslog 3
+loggings to be verbose.

+.Nm bootparams
+.Nd boot parameter database
+.Sh SYNOPSIS
+.Nm /etc/bootparams
+.Sh DESCRIPTION
+The
+.Nm
+file specifies the boot parameters that
+.Xr diskless 8
+clients may request when booting over the network.
+Each client supported by this server must have an entry in the
+.Nm
+file containing the pathnames for its
+.Dq root
+and (optionally)
+.Dq swap
+areas.
+.Pp
+Each line in the file
+(other than comment lines that begin with a
+.Ql # )
+specifies the client name followed by the pathnames that
+the client may request by their logical names.
+The components of the line are delimited with blank or tab,
+and may be continued onto multiple lines with a backslash.
+.Pp
+For example:
+.Bd -literal -offset indent
+dummy	root=host:/export/dummy/root \\
+	swap=host:/export/dummy/swap \\
+	dump=host:/export/dummy/swap
+.Ed
+.Pp
+When the client named
+.Dq dummy
+requests the pathname for its logical
+.Dq root
+it will be given the pathname
+.Dq Pa host:/export/dummy/root
+as the response to its
+.Tn RPC
+request.
+The
+.Dq host:
+component must be supplied.

+.Bl -tag -width XXXXXXXXXXXX
+.It Fl d
+burn the CD-R/RW in DAO (disk at once) mode.
+.It Fl e
+eject the media when done.
+.It Fl f Ar device
+set the device to use for the burning process.
+.It Fl l
+read a list of image files from filename.
+.It Fl m
+close disk in multisession mode (otherwise disk is closed as singlesession).
+.It Fl n
+do not write gaps between data tracks in DAO mode.
+.It Fl p
+use preemphasis on audio tracks.
+.It Fl q
+quiet, do not print progress messages.
+.It Fl s Ar speed
+set the speed of the burner device.
+Defaults to 1.
+.It Fl t
+test write, do not actually write on the media.
+.It Fl v
+verbose, print extra progress messages.
+.El
+.Pp
+.Ar command
+may be one of:
+.Pp
+.Bl -tag -width XXXXXXXXXXXX
+.It Cm msinfo
+Show the first LBA of the last track on the media
+and the next writeable address on the media for use with the
+.Xr mkisofs 8 Ns 's
+.Fl C
+switch when adding additional data to ISO filesystems with extra sessions.
+.It Cm blank
+Blank a CD-RW medium.
+This uses the fast blanking method, so data are not physically overwritten,
+only those areas that make the media appear blank for further usage are erased.
+.It Cm erase
+Erase a CD-RW medium.
+This erases the entire media.
+Can take up to 1 hour to finish.
+.It Cm fixate
+Fixate the medium so that the TOC is generated and the media can be used
+in an ordinary CD drive.
+The driver defaults to creating singlesession media (see
+.Fl m
+option).
+Should be the last command to
+.Nm
+as the program exits when this has been done.
+Ignored in DAO mode (see
+.Fl d
+option).
+.It Cm raw | audio
+Set the write mode to produce audio (raw mode) tracks for the following
+images on the command line.
+.It Cm data | mode1
+Set the write mode to produce data (mode1) tracks for the following
+image files
+on the command line.
+.It Cm mode2
+Set the write mode to produce data (mode2) tracks for the following
+image files
+on the command line.
+.It Cm XAmode1
+Set the write mode to produce data (XAmode1) tracks for the following image
+files on the command line.
+.It Cm XAmode2
+Set the write mode to produce data (XAmode2) tracks for the following image
+files on the command line.
+.It Cm vcd
+Set the write mode to produce VCD/SVCD tracks for the following image files
+on the command line.
+This automatically sets DAO
+.Pq Fl d
+and
+.Dq "no gaps"
+.Pq Fl n
+modes.
+.It Ar file
+All other arguments are treated as filenames of images to write to the media,
+or in case the
+.Fl l
+option is used as files containing lists of images.
+.El
+.Pp
+Files whose length are not a multiple of the current media blocksize are
+quietly zero padded to fit the blocksize requirement.
+The conventional filename
+.Fl
+refers to stdin, and can only be used once.
+.Sh EXAMPLES
+The typical usage for burning a data CD-R:
+.Pp
+.Dl "burncd -f /dev/acd0c data file1 fixate"
+.Pp
+The typical usage for burning an audio CD-R:
+.Pp
+.Dl "burncd -f /dev/acd0c audio file1 file2 file3 fixate"
+.Pp
+The typical usage for burning an audio CD-R in DAO mode:
+.Pp
+.Dl "burncd -f /dev/acd0c -d audio file1 file2 file3"
+.Pp
+The typical usage for burning a mixed mode CD-R:
+.Pp
+.Dl "burncd -f /dev/acd0c data file1 audio file2 file3 fixate"
+.Pp
+The typical usage for burning from a compressed image file on stdin:
+.Pp
+.Dl "gunzip -c file.iso.gz | burncd -f /dev/acd0c data - fixate"
+.Pp
+In the examples above, the files burned to data CD-Rs are assumed to
+be ISO9660 filesystems.
+.Xr mkisofs 8 ,
+available in the
+.Fx
+Ports Collection, is commonly used to create ISO9660 filesystem images
+from a given directory tree.

+/*
+ * Compact Disc Control Utility by Serge V. Vakulenko <vak@cronyx.ru>.
+ * Based on the non-X based CD player by Jean-Marc Zucconi and
+ * Andrey A. Chernov.
+ *
+ * Fixed and further modified on 5-Sep-1995 by Jukka Ukkonen <jau@funet.fi>.
+ *
+ * 11-Sep-1995: Jukka A. Ukkonen <jau@funet.fi>
+ *              A couple of further fixes to my own earlier "fixes".
+ *
+ * 18-Sep-1995: Jukka A. Ukkonen <jau@funet.fi>
+ *              Added an ability to specify addresses relative to the
+ *              beginning of a track. This is in fact a variation of
+ *              doing the simple play_msf() call.
+ *
+ * 11-Oct-1995: Serge V.Vakulenko <vak@cronyx.ru>
+ *              New eject algorithm.
+ *              Some code style reformatting.

+.Nd check the syntax of the group file
+.Sh SYNOPSIS
+.Nm
+.Op Ar groupfile
+.Sh DESCRIPTION
+The
+.Nm
+utility
+scans the given file or, failing that, the system-wide group file for
+errors.
+Specifically, it checks that every non-blank, non-comment
+entry is composed of four colon-separated fields, that none of them
+contains whitespace, and that the third field (the group ID) is
+numeric.
+.Sh FILES
+.Bl -tag -width /etc/group -compact
+.It Pa /etc/group
+group database file
+.El
+.Sh SEE ALSO
+.Xr getgrent 3 ,
+.Xr group 5
+.Sh DIAGNOSTICS
+For each error found,
+.Nm
+will print an error message containing the name of the file being
+scanned and the line number on which the error was found.
+Otherwise no
+output is produced.
+.Pp
+The
+.Nm
+utility returns
+.Dv EX_DATAERR
+if errors were found in the group file,
+and
+.Dv EX_OK
+otherwise.
+.Sh HISTORY
+The
+.Nm
+utility appeared in
+.Fx 3.0 .
+.Sh AUTHORS
+The
+.Nm
+utility and this manual page were written by
+.An Dag-Erling Co\(:idan Sm\(/orgrav Aq des@FreeBSD.org .
+.Sh BUGS
+Should check fields more thoroughly for allowed/disallowed
+characters, and the range of the group ID.

+Previous versions of the

+.Sh NAME
+.Nm ckdist
+.Nd check software distributions
+.Sh SYNOPSIS
+.Nm
+.Bq Fl airsx
+.Bq Fl d Ar dir
+.Bq Fl n Ar name
+.Bq Fl t Ar type
+.Ar
+.Sh DESCRIPTION
+The
+.Nm
+utility reads "checksum" files (which are assumed to specify components
+of a software distribution) and verifies the integrity of the
+distribution by validating the checksum of each component file.
+Both MD5 (128-bit "message digest") and .inf (32-bit CRC) checksum
+formats are supported.
+.Pp
+The
+.Ar file
+operands may refer to regular files or to directories.  Regular files
+named "md5", or which have an ".md5" or an ".inf" extension, are
+assumed to be of the implied type, otherwise format is determined from
+content.  If a directory is specified, it is searched for
+appropriately-named files only.
+.Pp
+Options are as follows:
+.Bl -tag -width 8n -offset indent
+.It Fl a
+Report on all distribution components, not just those in respect of
+which errors are detected.
+.It Fl i
+Ignore missing distribution components.
+.It Fl r
+Search specified directories recursively.
+.It Fl s
+Suppress complaints about inaccessible checksum files and directories.
+.It Fl x
+Verify the existence of distribution components (and also check sizes,
+in the case of .inf files), but omit the more time-consuming step of
+actually computing and comparing checksums.
+.It Fl d Ar dir
+Look for distribution components in the directory
+.Ar dir .
+.It Fl n Ar name
+Access distribution components using the filename
+.Ar name .
+When accessing .inf file components, append the appropriate
+extension to the filename.
+.It Fl t Ar type
+Assume that all specified checksum files are of the format
+.Ar type ,
+and search directories only for files in this format (where
+.Ar type
+is either "md5" or "inf").
+.El
+.Sh SEE ALSO
+.Xr cksum 1 ,
+.Xr md5 1
+.Sh DIAGNOSTICS
+Exit status is 0 if no errors were detected, 1 if errors were found in
+a distribution, and 2 if usage errors, inaccessible input files, or
+other system errors were encountered.
+.Sh NOTES
+Both
+.Bx
+and
+.Tn DOS
+versions of
+.Nm
+are available.

+INTRODUCTION
+.PP
+.I Config
+is a tool used in building 4.4BSD system images (the UNIX kernel).
+It takes a file describing a system's tunable parameters and
+hardware support, and generates a collection
+of files which are then used to build a copy of UNIX appropriate
+to that configuration.
+.I Config
+simplifies system maintenance by isolating system dependencies
+in a single, easy to understand, file.
+.PP
+This document describes the content and 
+format of system configuration
+files and the rules which must be followed when creating 
+these files.  Example configuration files are constructed
+and discussed.
+.PP
+Later sections suggest guidelines to be used in modifying
+system source and explain some of the inner workings of the
+autoconfiguration process.  Appendix D summarizes the rules
+used in calculating the most important system data structures
+and indicates some inherent system data structure size
+limitations (and how to go about modifying them).

+.\".ds RH "Configuration File Contents
+.ne 2i
+.NH
+CONFIGURATION FILE CONTENTS
+.PP
+A system configuration must include at least the following
+pieces of information:
+.IP \(bu 3
+machine type
+.IP \(bu 3
+cpu type
+.IP \(bu 3
+system identification
+.IP \(bu 3
+timezone
+.IP \(bu 3
+maximum number of users
+.IP \(bu 3
+location of the root file system
+.IP \(bu 3
+available hardware
+.PP
+.I Config
+allows multiple system images to be generated from a single
+configuration description.  Each system image is configured
+for identical hardware, but may have different locations for the root
+file system and, possibly, other system devices.
+.NH 2
+Machine type
+.PP
+The 
+.I "machine type"
+indicates if the system is going to operate on a DEC VAX-11\(dg computer,
+.FS
+\(dg DEC, VAX, UNIBUS, MASSBUS and MicroVAX are trademarks of Digital
+Equipment Corporation.
+.FE
+or some other machine on which 4.4BSD operates.  The machine type
+is used to locate certain data files which are machine specific, and
+also to select rules used in constructing the resultant
+configuration files.
+.NH 2
+Cpu type
+.PP
+The
+.I "cpu type"
+indicates which, of possibly many, cpu's the system is to operate on.
+For example, if the system is being configured for a VAX-11, it could
+be running on a VAX 8600, VAX-11/780, VAX-11/750, VAX-11/730 or MicroVAX II.
+(Other VAX cpu types, including the 8650, 785 and 725, are configured using
+the cpu designation for compatible machines introduced earlier.)
+Specifying
+more than one cpu type implies that the system should be configured to run
+on any of the cpu's specified.  For some types of machines this is not
+possible and 
+.I config
+will print a diagnostic indicating such.
+.NH 2
+System identification
+.PP
+The
+.I "system identification"
+is a moniker attached to the system, and often the machine on which the
+system is to run.  For example, at Berkeley we have machines named Ernie
+(Co-VAX), Kim (No-VAX), and so on.  The system identifier selected is used to
+create a global C ``#define'' which may be used to isolate system dependent
+pieces of code in the kernel.  For example, Ernie's Varian driver used
+to be special cased because its interrupt vectors were wired together.  The
+code in the driver which understood how to handle this non-standard hardware
+configuration was conditionally compiled in only if the system
+was for Ernie.  
+.PP
+The system identifier ``GENERIC'' is given to a system which
+will run on any cpu of a particular machine type; it should not
+otherwise be used for a system identifier.
+.NH 2
+Timezone
+.PP
+The timezone in which the system is to run is used to define the
+information returned by the \fIgettimeofday\fP\|(2)
+system call.  This value is specified as the number of hours east
+or west of GMT.  Negative numbers indicate a value east of GMT.
+The timezone specification may also indicate the
+type of daylight savings time rules to be applied.
+.NH 2
+Maximum number of users
+.PP
+The system allocates many system data structures at boot time
+based on the maximum number of users the system will support.
+This number is normally between 8 and 40, depending
+on the hardware and expected job mix.  The rules
+used to calculate system data structures are discussed in
+Appendix D.
+.NH 2
+Root file system location
+.PP
+When the system boots it must know the location of
+the root of the file system
+tree.  This location and the part(s) of the disk(s) to be used
+for paging and swapping must be specified in order to create
+a complete configuration description.  
+.I Config
+uses many rules to calculate default locations for these items;
+these are described in Appendix B.
+.PP
+When a generic system is configured, the root file system is left
+undefined until the system is booted.  In this case, the root file
+system need not be specified, only that the system is a generic system.
+.NH 2
+Hardware devices
+.PP
+When the system boots it goes through an
+.I autoconfiguration
+phase.  During this period, the system searches for all
+those hardware devices
+which the system builder has indicated might be present.  This probing
+sequence requires certain pieces of information such as register
+addresses, bus interconnects, etc.  A system's hardware may be configured
+in a very flexible manner or be specified without any flexibility
+whatsoever.  Most people do not configure hardware devices into the
+system unless they are currently present on the machine, expect
+them to be present in the near future, or are simply guarding
+against a hardware
+failure somewhere else at the site (it is often wise to configure in
+extra disks in case an emergency requires moving one off a machine which
+has hardware problems).
+.PP
+The specification of hardware devices usually occupies the majority of
+the configuration file.  As such, a large portion of this document will
+be spent understanding it.  Section 6.3 contains a description of
+the autoconfiguration process, as it applies to those planning to
+write, or modify existing, device drivers.
+.NH 2
+Pseudo devices
+.PP
+Several system facilities are configured in a manner like that used
+for hardware devices although they are not associated with specific hardware.
+These system options are configured as
+.IR pseudo-devices .
+Some pseudo devices allow an optional parameter that sets the limit
+on the number of instances of the device that are active simultaneously.
+.NH 2
+System options
+.PP
+Other than the mandatory pieces of information described above, it
+is also possible to include various optional system facilities
+or to modify system behavior and/or limits.
+For example, 4.4BSD can be configured to support binary compatibility for
+programs built under 4.3BSD.  Also, optional support is provided
+for disk quotas and tracing the performance of the virtual memory
+subsystem.  Any optional facilities to be configured into
+the system are specified in the configuration file.  The resultant
+files generated by

+SYSTEM BUILDING PROCESS
+.PP
+In this section we consider the steps necessary to build a bootable system
+image.  We assume the system source is located in the ``/sys'' directory
+and that, initially, the system is being configured from source code.
+.PP
+Under normal circumstances there are 5 steps in building a system.
+.IP 1) 3
+Create a configuration file for the system.
+.IP 2) 3
+Make a directory for the system to be constructed in.
+.IP 3) 3
+Run
+.I config
+on the configuration file to generate the files required
+to compile and load the system image.
+.IP 4)
+Construct the source code interdependency rules for the
+configured system with
+.I make depend
+using
+.IR make (1).
+.IP 5)
+Compile and load the system with 
+.IR make .
+.PP
+Steps 1 and 2 are usually done only once.  When a system configuration
+changes it usually suffices to just run
+.I config
+on the modified configuration file, rebuild the source code dependencies,
+and remake the system.  Sometimes,
+however, configuration dependencies may not be noticed in which case
+it is necessary to clean out the relocatable object files saved
+in the system's directory; this will be discussed later.
+.NH 2
+Creating a configuration file
+.PP
+Configuration files normally reside in the directory ``/sys/conf''.
+A configuration file is most easily constructed by copying an
+existing configuration file and modifying it.  The 4.4BSD distribution
+contains a number of configuration files for machines at Berkeley;
+one may be suitable or, in worst case, a copy
+of the generic configuration file may be edited.
+.PP
+The configuration file must have the same name as the directory in
+which the configured system is to be built.  
+Further,
+.I config
+assumes this directory is located in the parent directory of
+the directory in which it
+is run.  For example, the generic
+system has a configuration file ``/sys/conf/GENERIC'' and an accompanying
+directory named ``/sys/GENERIC''.
+Although it is not required that the system sources and configuration
+files reside in ``/sys,'' the configuration and compilation procedure
+depends on the relative locations of directories within that hierarchy,
+as most of the system code and the files created by
+.I config
+use pathnames of the form ``../''.
+If the system files are not located in ``/sys,''
+it is desirable to make a symbolic link there for use in installation
+of other parts of the system that share files with the kernel.
+.PP
+When building the configuration file, be sure to include the items
+described in section 2.  In particular, the machine type,
+cpu type, timezone, system identifier, maximum users, and root device
+must be specified.  The specification of the hardware present may take
+a bit of work; particularly if your hardware is configured at non-standard
+places (e.g. device registers located at funny places or devices not
+supported by the system).  Section 4 of this document
+gives a detailed description of the configuration file syntax,
+section 5 explains some sample configuration files, and
+section 6 discusses how to add new devices to
+the system.  If the devices to be configured are not already
+described in one of the existing configuration files you should check
+the manual pages in section 4 of the UNIX Programmers Manual.  For each
+supported device, the manual page synopsis entry gives a
+sample configuration line.
+.PP
+Once the configuration file is complete, run it through
+.I config
+and look for any errors.  Never try and use a system which
+.I config
+has complained about; the results are unpredictable.
+For the most part,
+.IR config 's
+error diagnostics are self explanatory.  It may be the case that
+the line numbers given with the error messages are off by one.
+.PP
+A successful run of
+.I config
+on your configuration file will generate a number of files in
+the configuration directory.  These files are:
+.IP \(bu 3
+A file to be used by \fImake\fP\|(1)
+in compiling and loading the system,
+.IR Makefile .
+.IP \(bu 3
+One file for each possible system image for this machine,
+.IR swapxxx.c ,
+where
+.I xxx
+is the name of the system image,
+which describes where swapping, the root file system, and other
+miscellaneous system devices are located.
+.IP \(bu 3
+A collection of header files, one per possible device the
+system supports, which define the hardware configured.
+.IP \(bu 3
+A file containing the I/O configuration tables used by the system
+during its 
+.I autoconfiguration
+phase,
+.IR ioconf.c .
+.IP \(bu 3
+An assembly language file of interrupt vectors which
+connect interrupts from the machine's external buses to the main
+system path for handling interrupts,
+and a file that contains counters and names for the interrupt vectors.
+.PP
+Unless you have reason to doubt 
+.IR config ,
+or are curious how the system's autoconfiguration scheme
+works, you should never have to look at any of these files.
+.NH 2
+Constructing source code dependencies
+.PP
+When 
+.I config
+is done generating the files needed to compile and link your system it
+will terminate with a message of the form ``Don't forget to run make depend''.
+This is a reminder that you should change over to the configuration
+directory for the system just configured and type ``make depend''
+to build the rules used by 
+.I make
+to recognize interdependencies in the system source code.
+This will insure that any changes to a piece of the system
+source code will result in the proper modules being recompiled
+the next time
+.I make
+is run.
+.PP
+This step is particularly important if your site makes changes
+to the system include files.  The rules generated specify which source code
+files are dependent on which include files.  Without these rules,
+.I make
+will not recognize when it must rebuild modules
+due to the modification of a system header file.
+The dependency rules are generated by a pass of the C preprocessor
+and reflect the global system options.
+This step must be repeated when the configuration file is changed
+and
+.I config
+is used to regenerate the system makefile.
+.NH 2
+Building the system
+.PP
+The makefile constructed by
+.I config
+should allow a new system to be rebuilt by simply typing ``make image-name''.
+For example, if you have named your bootable system image ``kernel'',
+then ``make kernel''
+will generate a bootable image named ``kernel''.  Alternate system image names
+are used when the root file system location and/or swapping configuration
+is done in more than one way.  The makefile which
+.I config
+creates has entry points for each system image defined in
+the configuration file.
+Thus, if you have configured ``kernel'' to be a system with the root file
+system on an ``hp'' device and ``hkkernel'' to be a system with the root
+file system on an ``hk'' device, then ``make kernel hkkernel'' will generate
+binary images for each.
+As the system will generally use the disk from which it is loaded
+as the root filesystem, separate system images are only required
+to support different swap configurations.
+.PP
+Note that the name of a bootable image is different from the system
+identifier.  All bootable images are configured for the same system;
+only the information about the root file system and paging devices differ.
+(This is described in more detail in section 4.)
+.PP
+The last step in the system building process is to rearrange certain commonly
+used symbols in the symbol table of the system image;  the makefile
+generated by 
+.I config
+does this automatically for you.
+This is advantageous for programs such as
+\fInetstat\fP\|(1) and \fIvmstat\fP\|(1),
+which run much faster when the symbols they need are located at
+the front of the symbol table.  
+Remember also that many programs expect
+the currently executing system to be named ``/kernel''.  If you install
+a new system and name it something other than ``/kernel'', many programs
+are likely to give strange results.
+.NH 2
+Sharing object modules
+.PP
+If you have many systems which are all built on a single machine
+there are at least two approaches to saving time in building system
+images.  The best way is to have a single system image which is run on
+all machines.  This is attractive since it minimizes disk space used
+and time required to rebuild systems after making changes.  However,
+it is often the case that one or more systems will require a separately
+configured system image.  This may be due to limited memory (building
+a system with many unused device drivers can be expensive), or to
+configuration requirements (one machine may be a development machine
+where disk quotas are not needed, while another is a production machine
+where they are), etc.  In these cases it is possible
+for common systems to share relocatable object modules which are not
+configuration dependent; most of the modules in the directory ``/sys/sys''
+are of this sort.
+.PP
+To share object modules, a generic system should be built.  Then, for
+each system configure the system as before, but before recompiling and
+linking the system, type ``make links'' in the system compilation directory.
+This will cause the system
+to be searched for source modules which are safe to share between systems
+and generate symbolic links in the current directory to the appropriate
+object modules in the directory ``../GENERIC''.  A shell script,
+``makelinks'' is generated with this request and may be checked for
+correctness.  The file ``/sys/conf/defines'' contains a list of symbols
+which we believe are safe to ignore when checking the source code
+for modules which may be shared.  Note that this list includes the definitions
+used to conditionally compile in the virtual memory tracing facilities, and
+the trace point support used only rarely (even at Berkeley). 
+It may be necessary
+to modify this file to reflect local needs.  Note further that
+interdependencies which are not directly visible
+in the source code are not caught.  This means that if you place
+per-system dependencies in an include file, they will not be recognized
+and the shared code may be selected in an unexpected fashion.
+.NH 2
+Building profiled systems
+.PP
+It is simple to configure a system which will automatically
+collect profiling information as it operates.  The profiling data
+may be collected with \fIkgmon\fP\|(8) and processed with
+\fIgprof\fP\|(1)
+to obtain information regarding the system's operation.  Profiled
+systems maintain histograms of the program counter as well as the
+number of invocations of each routine.  The \fIgprof\fP
+command will also generate a dynamic call graph of the executing
+system and propagate time spent in each routine along the arcs
+of the call graph (consult the \fIgprof\fP documentation for elaboration).
+The program counter sampling can be driven by the system clock, or
+if you have an alternate real time clock, this can be used.  The 
+latter is highly recommended, as use of the system clock will result
+in statistical anomalies, and time spent in the clock routine will
+not be accurately attributed.
+.PP
+To configure a profiled system, the
+.B \-p
+option should be supplied to \fIconfig\fP.
+A profiled system is about 5-10% larger in its text space due to
+the calls to count the subroutine invocations.  When the system
+executes, the profiling data is stored in a buffer which is 1.2
+times the size of the text space.  The overhead for running a
+profiled system varies; under normal load we see anywhere from 5-25%
+of the system time spent in the profiling code.
+.PP
+Note that systems configured for profiling should not be shared as
+described above unless all the other shared systems are also to be
+profiled.

+.NH
+CONFIGURATION FILE SYNTAX
+.PP
+In this section we consider the specific rules used in writing
+a configuration file.  A complete grammar for the input language
+can be found in Appendix A and may be of use if you should have
+problems with syntax errors.
+.PP
+A configuration file is broken up into three logical pieces:
+.IP \(bu 3
+configuration parameters global to all system images 
+specified in the configuration file,
+.IP \(bu 3
+parameters specific to each
+system image to be generated, and
+.IP \(bu 3
+device specifications.
+.NH 2
+Global configuration parameters
+.PP
+The global configuration parameters are the type of machine,
+cpu types, options, timezone, system identifier, and maximum users.
+Each is specified with a separate line in the configuration file.
+.IP "\fBmachine\fP \fItype\fP"
+.br
+The system is to run on the machine type specified.  No more than
+one machine type can appear in the configuration file.  Legal values
+are
+.B vax
+and
+\fBsun\fP.
+.IP "\fBcpu\fP ``\fItype\fP''"
+.br
+This system is to run on the cpu type specified.
+More than one cpu type specification
+can appear in a configuration file.
+Legal types for a
+.B vax
+machine are
+\fBVAX8600\fP, \fBVAX780\fP, \fBVAX750\fP,
+\fBVAX730\fP
+and
+\fBVAX630\fP (MicroVAX II).
+The 8650 is listed as an 8600, the 785 as a 780, and a 725 as a 730.
+.IP "\fBoptions\fP \fIoptionlist\fP"
+.br
+Compile the listed optional code into the system. 
+Options in this list are separated by commas.
+Possible options are listed at the top of the generic makefile.
+A line of the form ``options FUNNY,HAHA'' generates global ``#define''s
+\-DFUNNY \-DHAHA in the resultant makefile.
+An option may be given a value by following its name with ``\fB=\fP'',
+then the value enclosed in (double) quotes.
+The following are major options are currently in use:
+COMPAT (include code for compatibility with 4.1BSD binaries),
+INET (Internet communication protocols),
+NS (Xerox NS communication protocols),
+and
+QUOTA (enable disk quotas).
+Other kernel options controlling system sizes and limits
+are listed in Appendix D;
+options for the network are found in Appendix E.
+There are additional options which are associated with certain
+peripheral devices; those are listed in the Synopsis section
+of the manual page for the device.
+.IP "\fBmakeoptions\fP \fIoptionlist\fP"
+.br
+Options that are used within the system makefile
+and evaluated by
+.I make
+are listed as
+.IR makeoptions .
+Options are listed with their values with the form
+``makeoptions name=value,name2=value2.''
+The values must be enclosed in double quotes if they include numerals
+or begin with a dash.
+.IP "\fBtimezone\fP \fInumber\fP [ \fBdst\fP [ \fInumber\fP ] ]"
+.br
+Specifies the timezone used by the system.  This is measured in the
+number of hours your timezone is west of GMT.  
+EST is 5 hours west of GMT, PST is 8.  Negative numbers
+indicate hours east of GMT. If you specify
+\fBdst\fP, the system will operate under daylight savings time.
+An optional integer or floating point number may be included
+to specify a particular daylight saving time correction algorithm;
+the default value is 1, indicating the United States.
+Other values are: 2 (Australian style), 3 (Western European),
+4 (Middle European), and 5 (Eastern European).  See
+\fIgettimeofday\fP\|(2) and \fIctime\fP\|(3) for more information.
+.IP "\fBident\fP \fIname\fP"
+.br
+This system is to be known as
+.IR name .
+This is usually a cute name like ERNIE (short for Ernie Co-Vax) or
+VAXWELL (for Vaxwell Smart).
+This value is defined for use in conditional compilation,
+and is also used to locate an optional list of source files specific
+to this system.
+.IP "\fBmaxusers\fP \fInumber\fP"
+.br
+The maximum expected number of simultaneously active user on this system is
+.IR number .
+This number is used to size several system data structures.
+.NH 2
+System image parameters
+.PP
+Multiple bootable images may be specified in a single configuration
+file.  The systems will have the same global configuration parameters
+and devices, but the location of the root file system and other
+system specific devices may be different.  A system image is specified
+with a ``config'' line:
+.IP
+\fBconfig\fP\ \fIsysname\fP\ \fIconfig-clauses\fP
+.LP
+The
+.I sysname
+field is the name given to the loaded system image; almost everyone
+names their standard system image ``kernel''.  The configuration clauses
+are one or more specifications indicating where the root file system
+is located and the number and location of paging devices.
+The device used by the system to process argument lists during
+.IR execve (2)
+calls may also be specified, though in practice this is almost
+always selected by
+.I config
+using one of its rules for selecting default locations for
+system devices.
+.PP
+A configuration clause is one of the following
+.IP
+.nf
+\fBroot\fP [ \fBon\fP ] \fIroot-device\fP
+\fBswap\fP [ \fBon\fP ] \fIswap-device\fP [ \fBand\fP \fIswap-device\fP ] ...
+\fBdumps\fP [ \fBon\fP ] \fIdump-device\fP
+\fBargs\fP [ \fBon\fP ] \fIarg-device\fP
+.LP
+(the ``on'' is optional.)  Multiple configuration clauses
+are separated by white space; 
+.I config
+allows specifications to be continued across multiple lines
+by beginning the continuation line with a tab character.
+The ``root'' clause specifies where the root file system
+is located, the ``swap'' clause indicates swapping and paging
+area(s), the ``dumps'' clause can be used to force system dumps
+to be taken on a particular device, and the ``args'' clause
+can be used to specify that argument list processing for
+.I execve
+should be done on a particular device.
+.PP
+The device names supplied in the clauses may be fully specified
+as a device, unit, and file system partition; or underspecified
+in which case
+.I config
+will use builtin rules to select default unit numbers and file
+system partitions.  The defaulting rules are a bit complicated
+as they are dependent on the overall system configuration.
+For example, the swap area need not be specified at all if 
+the root device is specified; in this case the swap area is
+placed in the ``b'' partition of the same disk where the root
+file system is located.  Appendix B contains a complete list
+of the defaulting rules used in selecting system configuration
+devices.
+.PP
+The device names are translated to the
+appropriate major and minor device
+numbers on a per-machine basis.  A file,
+``/sys/conf/devices.machine'' (where ``machine''
+is the machine type specified in the configuration file),
+is used to map a device name to its major block device number.
+The minor device number is calculated using the standard 
+disk partitioning rules: on unit 0, partition ``a'' is minor device
+0, partition ``b'' is minor device 1, and so on; for units
+other than 0, add 8 times the unit number to get the minor
+device.
+.PP
+If the default mapping of device name to major/minor device
+number is incorrect for your configuration, it can be replaced
+by an explicit specification of the major/minor device.
+This is done by substituting
+.IP
+\fBmajor\fP \fIx\fP \fBminor\fP \fIy\fP
+.LP
+where the device name would normally be found.  For example,
+.IP
+.nf
+\fBconfig\fP kernel \fBroot\fP \fBon\fP \fBmajor\fP 99 \fBminor\fP 1
+.fi
+.PP
+Normally, the areas configured for swap space are sized by the system
+at boot time.  If a non-standard size is to be used for one
+or more swap areas (less than the full partition),
+this can also be specified.  To do this, the
+device name specified for a swap area should have a ``size''
+specification appended.  For example,
+.IP
+.nf
+\fBconfig\fP kernel \fBroot\fP \fBon\fP hp0 \fBswap\fP \fBon\fP hp0b \fBsize\fP 1200
+.fi
+.LP
+would force swapping to be done in partition ``b'' of ``hp0'' and
+the swap partition size would be set to 1200 sectors.  A swap area
+sized larger than the associated disk partition is trimmed to the
+partition size.
+.PP
+To create a generic configuration, only the clause ``swap generic''
+should be specified; any extra clauses will cause an error.
+.NH 2
+Device specifications
+.PP
+Each device attached to a machine must be specified
+to
+.I config
+so that the system generated will know to probe for it during
+the autoconfiguration process carried out at boot time.  Hardware
+specified in the configuration need not actually be present on
+the machine where the generated system is to be run.  Only the
+hardware actually found at boot time will be used by the system.
+.PP
+The specification of hardware devices in the configuration file
+parallels the interconnection hierarchy of the machine to be
+configured.  On the VAX, this means that a configuration file must
+indicate what MASSBUS and UNIBUS adapters are present, and to
+which \fInexi\fP they might be connected.* 
+.FS
+* While VAX-11/750's and VAX-11/730 do not actually have 
+nexi, the system treats them as having 
+.I "simulated nexi"
+to simplify device configuration.
+.FE
+Similarly, devices
+and controllers must be indicated as possibly being connected
+to one or more adapters.  A device description may provide a
+complete definition of the possible configuration parameters
+or it may leave certain parameters undefined and make the system
+probe for all the possible values.  The latter allows a single
+device configuration list to match many possible physical
+configurations.  For example, a disk may be indicated as present
+at UNIBUS adapter 0, or at any UNIBUS adapter which the system
+locates at boot time.  The latter scheme, termed 
+.IR wildcarding ,
+allows more flexibility in the physical configuration of a system;
+if a disk must be moved around for some reason, the system will
+still locate it at the alternate location.
+.PP
+A device specification takes one of the following forms:
+.IP
+.nf
+\fBmaster\fP \fIdevice-name\fP \fIdevice-info\fP
+\fBcontroller\fP \fIdevice-name\fP \fIdevice-info\fP [ \fIinterrupt-spec\fP ]
+\fBdevice\fP \fIdevice-name\fP \fIdevice-info\fP \fIinterrupt-spec\fP
+\fBdisk\fP \fIdevice-name\fP \fIdevice-info\fP
+\fBtape\fP \fIdevice-name\fP \fIdevice-info\fP
+.fi
+.LP
+A ``master'' is a MASSBUS tape controller; a ``controller'' is a
+disk controller, a UNIBUS tape controller, a MASSBUS adapter, or
+a UNIBUS adapter.  A ``device'' is an autonomous device which
+connects directly to a UNIBUS adapter (as opposed to something
+like a disk which connects through a disk controller).  ``Disk''
+and ``tape'' identify disk drives and tape drives connected to
+a ``controller'' or ``master.''
+.PP
+The
+.I device-name
+is one of the standard device names, as
+indicated in section 4 of the UNIX Programmers Manual,
+concatenated with the
+.I logical
+unit number to be assigned the device (the 
+.I logical
+unit number may be different than the
+.I physical
+unit number indicated on the front of something
+like a disk; the
+.I logical
+unit number is used to refer to the UNIX device, not
+the physical unit number).  For example, ``hp0'' is logical
+unit 0 of a MASSBUS storage device, even though it might
+be physical unit 3 on MASSBUS adapter 1.
+.PP
+The
+.I device-info
+clause specifies how the hardware is
+connected in the interconnection hierarchy.  On the VAX,
+UNIBUS and MASSBUS adapters are connected to the internal
+system bus through
+a \fInexus\fP.
+Thus, one of the following
+specifications would be used:
+.IP
+.ta 1.5i 2.5i 4.0i
+.nf
+\fBcontroller\fP	mba0	\fBat\fP \fBnexus\fP \fIx\fP
+\fBcontroller\fP	uba0	\fBat\fP \fBnexus\fP \fIx\fP
+.fi
+.LP
+To tie a controller to a specific nexus, ``x'' would be supplied
+as the number of that nexus; otherwise ``x'' may be specified as
+``?'', in which
+case the system will probe all nexi present looking
+for the specified controller.
+.PP
+The remaining interconnections on the VAX are:
+.IP \(bu 3
+a controller
+may be connected to another controller (e.g. a disk controller attached
+to a UNIBUS adapter),
+.IP \(bu 3

+.LP
+Any piece of hardware which may be connected to a specific

+.PP
+The final piece of information needed by the system to configure
+devices is some indication of where or how a device will interrupt.
+For tapes and disks, simply specifying the \fIslave\fP or \fIdrive\fP
+number is sufficient to locate the control status register for the
+device.
+\fIDrive\fP numbers may be wildcarded
+on MASSBUS devices, but not on disks on a UNIBUS controller.
+For controllers, the control status register must be
+given explicitly, as well the number of interrupt vectors used and
+the names of the routines to which they should be bound. 
+Thus the example lines given above might be completed as:
+.IP

+\fBdevice\fP	dz0	\fBat\fP uba0 \fBcsr\fP 0160100	\fBvector\fP dzrint dzxint
+.fi
+.PP
+Certain device drivers require extra information passed to them
+at boot time to tailor their operation to the actual hardware present.
+The line printer driver, for example, needs to know how many columns
+are present on each non-standard line printer (i.e. a line printer
+with other than 80 columns).  The drivers for the terminal multiplexors
+need to know which lines are attached to modem lines so that no one will
+be allowed to use them unless a connection is present.  For this reason,
+one last parameter may be specified to a
+.IR device ,
+a 
+.I flags
+field.  It has the syntax
+.IP
+\fBflags\fP \fInumber\fP
+.LP
+and is usually placed after the
+.I csr
+specification.  The
+.I number
+is passed directly to the associated driver.  The manual pages
+in section 4 should be consulted to determine how each driver
+uses this value (if at all).
+Communications interface drivers commonly use the flags
+to indicate whether modem control signals are in use.
+.PP
+The exact syntax for each specific device is given in the Synopsis
+section of its manual page in section 4 of the manual.
+.NH 2
+Pseudo-devices
+.PP
+A number of drivers and software subsystems
+are treated like device drivers without any associated hardware.
+To include any of these pieces, a ``pseudo-device'' specification
+must be used.  A specification for a pseudo device takes the form
+.IP
+.DT
+.nf
+\fBpseudo-device\fP	\fIdevice-name\fP [ \fIhowmany\fP ]
+.fi
+.PP
+Examples of pseudo devices are
+\fBpty\fP, the pseudo terminal driver (where the optional
+.I howmany
+value indicates the number of pseudo terminals to configure, 32 default),
+and \fBloop\fP, the software loopback network pseudo-interface.
+Other pseudo devices for the network include
+\fBimp\fP (required when a CSS or ACC imp is configured)
+and \fBether\fP (used by the Address Resolution Protocol
+on 10 Mb/sec Ethernets).
+More information on configuring each of these can also be found
+in section 4 of the manual.

+SAMPLE CONFIGURATION FILES
+.PP
+In this section we will consider how to configure a
+sample VAX-11/780 system on which the hardware can be
+reconfigured to guard against various hardware mishaps.
+We then study the rules needed to configure a VAX-11/750
+to run in a networking environment.
+.NH 2
+VAX-11/780 System
+.PP
+Our VAX-11/780 is configured with hardware
+recommended in the document ``Hints on Configuring a VAX for 4.2BSD''
+(this is one of the high-end configurations).
+Table 1 lists the pertinent hardware to be configured.

+Table 1.  VAX-11/780 Hardware support.
+.LP
+We will call this machine ANSEL and construct a configuration
+file one step at a time.
+.PP
+The first step is to fill in the global configuration parameters.
+The machine is a VAX, so the
+.I "machine type"
+is ``vax''.  We will assume this system will
+run only on this one processor, so the 
+.I "cpu type"
+is ``VAX780''.  The options are empty since this is going to
+be a ``vanilla'' VAX.  The system identifier, as mentioned before,
+is ``ANSEL,'' and the maximum number of users we plan to support is
+about 40.  Thus the beginning of the configuration file looks like
+this:
+.DS
+.ta 1.5i 2.5i 4.0i
+#
+# ANSEL VAX (a picture perfect machine)
+#
+machine	vax
+cpu	VAX780
+timezone	8 dst
+ident	ANSEL
+maxusers	40
+.DE
+.PP
+To this we must then add the specifications for three
+system images.  The first will be our standard system with the
+root on ``hp0'' and swapping on the same drive as the root.
+The second will have the root file system in the same location,
+but swap space interleaved among drives on each controller.
+Finally, the third will be a generic system,
+to allow us to boot off any of the four disk drives.
+.DS
+.ta 1.5i 2.5i
+config	kernel	root on hp0
+config	hpkernel	root on hp0 swap on hp0 and hp2
+config	genkernel	swap generic
+.DE
+.PP
+Finally, the hardware must be specified.  Let us first just try
+transcribing the information from Table 1.
+.DS
+.ta 1.5i 2.5i 4.0i

+disk	hp0	at mba0 disk 0

+.DE
+.LP
+(Oh, I forgot to mention one panel of the terminal multiplexor
+has modem control, thus the ``dm0'' device.)
+.PP
+This will suffice, but leaves us with little flexibility.  Suppose
+our first disk controller were to break.  We would like to recable the
+drives normally on the second controller so that all our disks could
+still be used without reconfiguring the system.  To do this we wildcard
+the MASSBUS adapter connections and also the slave numbers.  Further,
+we wildcard the UNIBUS adapter connections in case we decide some time
+in the future to purchase another adapter to offload the single UNIBUS
+we currently have.  The revised device specifications would then be:
+.DS

+.NH 2
+VAX-11/750 with network support
+.PP
+Our VAX-11/750 system will be located on two 10Mb/s Ethernet
+local area networks and also the DARPA Internet.  The system
+will have a MASSBUS drive for the root file system and two
+UNIBUS drives.  Paging is interleaved among all three drives.
+We have sold our standard DEC terminal multiplexors since this
+machine will be accessed solely through the network.  This
+machine is not intended to have a large user community, it
+does not have a great deal of memory.  First the global parameters:
+.DS
+.ta 1.5i 2.5i 4.0i
+#
+# UCBVAX (Gateway to the world)
+#
+machine	vax
+cpu	"VAX780"
+cpu	"VAX750"
+ident	UCBVAX
+timezone	8 dst
+maxusers	32
+options	INET
+options	NS
+.DE
+.PP
+The multiple cpu types allow us to replace UCBVAX with a
+more powerful cpu without reconfiguring the system.  The
+value of 32 given for the maximum number of users is done to
+force the system data structures to be over-allocated.  That
+is desirable on this machine because, while it is not expected
+to support many users, it is expected to perform a great deal
+of work.
+The ``INET'' indicates that we plan to use the
+DARPA standard Internet protocols on this machine,
+and ``NS'' also includes support for Xerox NS protocols.
+Note that unlike 4.2BSD configuration files,
+the network protocol options do not require corresponding pseudo devices.
+.PP
+The system images and disks are configured next.
+.DS
+.ta 1.5i 2.5i 4.0i

+disk	rk1	at hk0 drive 1
+.DE
+.PP
+UCBVAX requires heavy interleaving of its paging area to keep up
+with all the mail traffic it handles.  The limiting factor on this
+system's performance is usually the number of disk arms, as opposed
+to memory or cpu cycles.  The extra UNIBUS controller, ``sc0'',
+is in case the MASSBUS controller breaks and a spare controller
+must be installed (most of our old UNIBUS controllers have been
+replaced with the newer MASSBUS controllers, so we have a number
+of these around as spares).
+.PP
+Finally, we add in the network devices.
+Pseudo terminals are needed to allow users to
+log in across the network (remember the only hardwired terminal
+is the console).
+The software loopback device is used for on-machine communications.
+The connection to the Internet is through
+an IMP, this requires yet another
+.I pseudo-device
+(in addition to the actual hardware device used by the
+IMP software).  And, finally, there are the two Ethernet devices.
+These use a special protocol, the Address Resolution Protocol (ARP),
+to map between Internet and Ethernet addresses.  Thus, yet another
+.I pseudo-device
+is needed.  The additional device specifications are show below.
+.DS

+.LP
+The completed configuration file for UCBVAX is shown in Appendix C.
+.NH 2
+Miscellaneous comments
+.PP
+It should be noted in these examples that neither system was
+configured to use disk quotas or the 4.1BSD compatibility mode.
+To use these optional facilities, and others, we would probably
+clean out our current configuration, reconfigure the system, then
+recompile and relink the system image(s).  This could, of course,
+be avoided by figuring out which relocatable object files are 
+affected by the reconfiguration, then reconfiguring and recompiling
+only those files affected by the configuration change.  This technique
+should be used carefully.

+ADDING NEW SYSTEM SOFTWARE
+.PP
+This section is not for the novice, it describes
+some of the inner workings of the configuration process as
+well as the pertinent parts of the system autoconfiguration process.
+It is intended to give
+those people who intend to install new device drivers and/or
+other system facilities sufficient information to do so in the
+manner which will allow others to easily share the changes.
+.PP
+This section is broken into four parts:
+.IP \(bu 3
+general guidelines to be followed in modifying system code,
+.IP \(bu 3
+how to add non-standard system facilities to 4.4BSD,
+.IP \(bu 3
+how to add a device driver to 4.4BSD, and
+.NH 2
+Modifying system code
+.PP
+If you wish to make site-specific modifications to the system
+it is best to bracket them with
+.DS
+#ifdef SITENAME
+\&...
+#endif
+.DE
+to allow your source to be easily distributed to others, and
+also to simplify \fIdiff\fP\|(1) listings.  If you choose not
+to use a source code control system (e.g. SCCS, RCS), and
+perhaps even if you do, it is
+recommended that you save the old code with something
+of the form:
+.DS
+#ifndef SITENAME
+\&...
+#endif
+.DE
+We try to isolate our site-dependent code in individual files
+which may be configured with pseudo-device specifications.
+.PP
+Indicate machine-specific code with ``#ifdef vax'' (or other machine,
+as appropriate).
+4.4BSD underwent extensive work to make it extremely portable to
+machines with similar architectures\- you may someday find
+yourself trying to use a single copy of the source code on
+multiple machines.
+.NH 2
+Adding non-standard system facilities
+.PP
+This section considers the work needed to augment 
+.IR config 's
+data base files for non-standard system facilities.
+.I Config
+uses a set of files that list the source modules that may be required
+when building a system.
+The data bases are taken from the directory in which
+.I config
+is run, normally /sys/conf.
+Three such files may be used:
+.IR files ,
+.IR files .machine,
+and
+.IR files .ident.
+The first is common to all systems,
+the second contains files unique to a single machine type,
+and the third is an optional list of modules for use on a specific machine.
+This last file may override specifications in the first two.
+The format of the 
+.I files
+file has grown somewhat complex over time.  Entries are normally of
+the form
+.IP
+.nf
+.DT
+\fIdir/source.c\fP	\fItype\fP	 \fIoption-list\fP \fImodifiers\fP
+.LP
+for example,
+.IP
+.nf
+.DT
+\fIvaxuba/foo.c\fP	\fBoptional\fP	foo	\fBdevice-driver\fP
+.LP
+The
+.I type
+is one of
+.B standard
+or
+.BR optional .
+Files marked as standard are included in all system configurations.
+Optional file specifications include a list of one or more system
+options that together require the inclusion of this module.
+The options in the list may be either names of devices that may
+be in the configuration file,
+or the names of system options that may be defined.
+An optional file may be listed multiple times with different options;
+if all of the options for any of the entries are satisfied,
+the module is included.
+.PP
+If a file is specified as a
+.IR device-driver ,
+any special compilation options for device drivers will be invoked.
+On the VAX this results in the use of the
+.B \-i
+option for the C optimizer.  This is required when pointer references
+are made to memory locations in the VAX I/O address space.
+.PP
+Two other optional keywords modify the usage of the file.
+.I Config
+understands that certain files are used especially for
+kernel profiling.  These files are indicated in the
+.I files
+files with a 
+.I profiling-routine
+keyword.  For example, the current profiling subroutines
+are sequestered off in a separate file with the following
+entry:
+.IP
+.nf
+.DT
+\fIsys/subr_mcount.c\fP	\fBoptional\fP	\fBprofiling-routine\fP
+.fi
+.LP
+The 
+.I profiling-routine
+keyword forces
+.I config
+not to compile the source file with the 
+.B \-pg
+option.
+.PP
+The second keyword which can be of use is the
+.I config-dependent
+keyword.  This causes
+.I config
+to compile the indicated module with the global configuration
+parameters.  This allows certain modules, such as
+.I machdep.c
+to size system data structures based on the maximum number
+of users configured for the system.
+.NH 2
+Adding device drivers to 4.4BSD
+.PP
+The I/O system and
+.I config
+have been designed to easily allow new device support to be added.
+The system source directories are organized as follows:
+.DS
+.TS
+lw(1.0i) l.
+/sys/h	machine independent include files
+/sys/sys	machine-independent system source files
+/sys/conf	site configuration files and basic templates
+/sys/net	network-protocol-independent, but network-related code
+/sys/netinet	DARPA Internet code
+/sys/netimp	IMP support code
+/sys/netns	Xerox NS code
+/sys/vax	VAX-specific mainline code
+/sys/vaxif	VAX network interface code
+/sys/vaxmba	VAX MASSBUS device drivers and related code
+/sys/vaxuba	VAX UNIBUS device drivers and related code
+.TE
+.DE
+.PP
+Existing block and character device drivers for the VAX 
+reside in ``/sys/vax'', ``/sys/vaxmba'', and ``/sys/vaxuba''.  Network
+interface drivers reside in ``/sys/vaxif''.  Any new device
+drivers should be placed in the appropriate source code directory
+and named so as not to conflict with existing devices.
+Normally, definitions for things like device registers are placed in
+a separate file in the same directory.  For example, the ``dh''
+device driver is named ``dh.c'' and its associated include file is
+named ``dhreg.h''.
+.PP
+Once the source for the device driver has been placed in a directory,
+the file ``/sys/conf/files.machine'', and possibly
+``/sys/conf/devices.machine'' should be modified.  The 
+.I files
+files in the conf directory contain a line for each C source or binary-only
+file in the system.  Those files which are machine independent are
+located in ``/sys/conf/files,'' while machine specific files
+are in ``/sys/conf/files.machine.''  The ``devices.machine'' file
+is used to map device names to major block device numbers.  If the device
+driver being added provides support for a new disk
+you will want to modify this file (the format is obvious).
+.PP
+In addition to including the driver in the
+.I files
+file, it must also be added to the device configuration tables.  These
+are located in ``/sys/vax/conf.c'', or similar for machines other than
+the VAX.  If you don't understand what to add to this file, you should
+study an entry for an existing driver. 
+Remember that the position in the
+device table specifies the major device number.
+The block major number is needed in the ``devices.machine'' file
+if the device is a disk.
+.PP
+With the configuration information in place, your configuration
+file appropriately modified, and a system reconfigured and rebooted
+you should incorporate the shell commands needed to install the special
+files in the file system to the file ``/dev/MAKEDEV'' or
+``/dev/MAKEDEV.local''.  This is discussed in the document ``Installing
+and Operating 4.4BSD''.

+APPENDIX B. RULES FOR DEFAULTING SYSTEM DEVICES
+.sp
+.R
+.NL
+.PP
+When \fIconfig\fP processes a ``config'' rule which does
+not fully specify the location of the root file system,
+paging area(s), device for system dumps, and device for
+argument list processing it applies a set of rules to
+define those values left unspecified.  The following list
+of rules are used in defaulting system devices.
+.IP 1) 3
+If a root device is not specified, the swap
+specification must indicate a ``generic'' system is to be built.
+.IP 2) 3
+If the root device does not specify a unit number, it
+defaults to unit 0.
+.IP 3) 3
+If the root device does not include a partition specification,
+it defaults to the ``a'' partition.
+.IP 4) 3
+If no swap area is specified, it defaults to the ``b''
+partition of the root device.
+.IP 5) 3
+If no device is specified for processing argument lists, the
+first swap partition is selected.
+.IP 6) 3
+If no device is chosen for system dumps, the first swap
+partition is selected (see below to find out where dumps are
+placed within the partition).
+.PP
+The following table summarizes the default partitions selected
+when a device specification is incomplete, e.g. ``hp0''.
+.DS
+.TS
+l l.
+Type	Partition
+_
+root	``a''
+swap	``b''
+args	``b''
+dumps	``b''
+.TE
+.DE
+.SH
+Multiple swap/paging areas
+.PP
+When multiple swap partitions are specified, the system treats the
+first specified as a ``primary'' swap area which is always used.
+The remaining partitions are then interleaved into the paging
+system at the time a
+.IR swapon (2)
+system call is made.  This is normally done at boot time with
+a call to
+.IR swapon (8)
+from the /etc/rc file.
+.SH
+System dumps
+.PP
+System dumps are automatically taken after a system crash,
+provided the device driver for the ``dumps'' device supports
+this.  The dump contains the contents of memory, but not
+the swap areas.  Normally the dump device is a disk in
+which case the information is copied to a location at the
+back of the partition.  The dump is placed in the back of the
+partition because the primary swap and dump device are commonly
+the same device and this allows the system to be rebooted without
+immediately overwriting the saved information.  When a dump has
+occurred, the system variable \fIdumpsize\fP 
+is set to a non-zero value indicating the size (in bytes) of
+the dump.  The \fIsavecore\fP\|(8)
+program then copies the information from the dump partition to
+a file in a ``crash'' directory and also makes a copy of the
+system which was running at the time of the crash (usually
+``/kernel'').  The offset to the system dump is defined in the
+system variable \fIdumplo\fP (a sector offset from
+the front of the dump partition). The 
+.I savecore
+program operates by reading the contents of \fIdumplo\fP, \fIdumpdev\fP,
+and \fIdumpmagic\fP from /dev/kmem, then comparing the value
+of \fIdumpmagic\fP read from /dev/kmem to that located in
+corresponding location in the dump area of the dump partition.
+If a match is found, 
+.I savecore
+assumes a crash occurred and reads \fIdumpsize\fP from the dump area
+of the dump partition.  This value is then used in copying the
+system dump.  Refer to 
+\fIsavecore\fP\|(8)
+for more information about its operation.
+.PP
+The value \fIdumplo\fP is calculated to be 
+.DS
+\fIdumpdev-size\fP \- \fImemsize\fP
+.DE
+where \fIdumpdev-size\fP is the size of the disk partition
+where system dumps are to be placed, and
+\fImemsize\fP is the size of physical memory.
+If the disk partition is not large enough to hold a full
+dump, \fIdumplo\fP is set to 0 (the start of the partition).

+.NL
+.PP
+Certain system data structures are sized at compile time
+according to the maximum number of simultaneous users expected,
+while others are calculated at boot time based on the
+physical resources present, e.g. memory.  This appendix lists
+both sets of rules and also includes some hints on changing
+built-in limitations on certain data structures.
+.SH
+Compile time rules
+.PP
+The file \fI/sys/conf\|/param.c\fP contains the definitions of
+almost all data structures sized at compile time.  This file
+is copied into the directory of each configured system to allow
+configuration-dependent rules and values to be maintained.
+(Each copy normally depends on the copy in /sys/conf,
+and global modifications cause the file to be recopied unless
+the makefile is modified.)
+The rules implied by its contents are summarized below (here
+MAXUSERS refers to the value defined in the configuration file
+in the ``maxusers'' rule).
+Most limits are computed at compile time and stored in global variables
+for use by other modules; they may generally be patched in the system
+binary image before rebooting to test new values.
+.IP \fBnproc\fP
+.br
+The maximum number of processes which may be running at any time.
+It is referred to in other calculations as NPROC and is defined to be
+.DS
+20 + 8 * MAXUSERS
+.DE
+.IP \fBntext\fP
+.br
+The maximum number of active shared text segments.
+The constant is intended to allow for network servers and common commands
+that remain in the table.
+It is defined as
+.DS
+36 + MAXUSERS.
+.DE
+.IP \fBninode\fP
+.br
+The maximum number of files in the file system which may be
+active at any time.  This includes files in use by users, as 
+well as directory files being read or written by the system
+and files associated with bound sockets in the UNIX IPC domain.
+It is defined as
+.DS
+(NPROC + 16 + MAXUSERS) + 32
+.DE
+.IP \fBnfile\fP
+.br
+The number of ``file table'' structures.  One file
+table structure is used for each open, unshared, file descriptor.
+Multiple file descriptors may reference a single file table
+entry when they are created through a \fIdup\fP call, or as the
+result of a \fIfork\fP.  This is defined to be
+.DS
+16 * (NPROC + 16 + MAXUSERS) / 10 + 32
+.DE
+.IP \fBncallout\fP
+.br
+The number of ``callout'' structures.  One callout
+structure is used per internal system event handled with
+a timeout.  Timeouts are used for terminal delays,
+watchdog routines in device drivers, protocol timeout processing, etc.
+This is defined as
+.DS
+16 + NPROC
+.DE
+.IP \fBnclist\fP
+.br
+The number of ``c-list'' structures.  C-list structures are
+used in terminal I/O, and currently each holds 60 characters.
+Their number is defined as
+.DS
+60 + 12 * MAXUSERS
+.DE
+.IP \fBnmbclusters\fP
+.br
+The maximum number of pages which may be allocated by the network.  
+This is defined as 256 (a quarter megabyte of memory) in /sys/h/mbuf.h.
+In practice, the network rarely uses this much memory.  It starts off
+by allocating 8 kilobytes of memory, then requesting more as 
+required.  This value represents an upper bound.
+.IP \fBnquota\fP
+.br
+The number of ``quota'' structures allocated.  Quota structures
+are present only when disc quotas are configured in the system.  One
+quota structure is kept per user.  This is defined to be
+.DS
+(MAXUSERS * 9) / 7 + 3
+.DE
+.IP \fBndquot\fP
+.br
+The number of ``dquot'' structures allocated.  Dquot structures
+are present only when disc quotas are configured in the system.
+One dquot structure is required per user, per active file system quota.
+That is, when a user manipulates a file on a file system on which
+quotas are enabled, the information regarding the user's quotas on
+that file system must be in-core.  This information is cached, so
+that not all information must be present in-core all the time.
+This is defined as
+.DS
+NINODE + (MAXUSERS * NMOUNT) / 4
+.DE
+where NMOUNT is the maximum number of mountable file systems.
+.LP
+In addition to the above values, the system page tables (used to
+map virtual memory in the kernel's address space) are sized at
+compile time by the SYSPTSIZE definition in the file /sys/vax/vmparam.h.
+This is defined to be
+.DS
+20 + MAXUSERS
+.DE
+pages of page tables. 
+Its definition affects
+the size of many data structures allocated at boot time because
+it constrains the amount of virtual memory which may be addressed
+by the running system.  This is often the limiting factor
+in the size of the buffer cache, in which case a message is printed
+when the system configures at boot time.
+.SH
+Run-time calculations
+.PP
+The most important data structures sized at run-time are those used in
+the buffer cache.  Allocation is done by allocating physical memory
+(and system virtual memory) immediately after the system
+has been started up; look in the file /sys/vax/machdep.c.
+The amount of physical memory which may be allocated to the buffer
+cache is constrained by the size of the system page tables, among
+other things.  While the system may calculate
+a large amount of memory to be allocated to the buffer cache,
+if the system page
+table is too small to map this physical
+memory into the virtual address space
+of the system, only as much as can be mapped will be used.
+.PP
+The buffer cache is comprised of a number of ``buffer headers''
+and a pool of pages attached to these headers.  Buffer headers
+are divided into two categories: those used for swapping and
+paging, and those used for normal file I/O.  The system tries
+to allocate 10% of the first two megabytes and 5% of the remaining
+available physical memory for the buffer
+cache (where \fIavailable\fP does not count that space occupied by
+the system's text and data segments).  If this results in fewer
+than 16 pages of memory allocated, then 16 pages are allocated.
+This value is kept in the initialized variable \fIbufpages\fP
+so that it may be patched in the binary image (to allow tuning
+without recompiling the system),
+or the default may be overridden with a configuration-file option.
+For example, the option \fBoptions BUFPAGES="3200"\fP
+causes 3200 pages (3.2M bytes) to be used by the buffer cache.
+A sufficient number of file I/O buffer headers are then allocated
+to allow each to hold 2 pages each.
+Each buffer maps 8K bytes.
+If the number of buffer pages is larger than can be mapped
+by the buffer headers, the number of pages is reduced.
+The number of buffer headers allocated
+is stored in the global variable \fInbuf\fP,
+which may be patched before the system is booted.
+The system option \fBoptions NBUF="1000"\fP forces the allocation
+of 1000 buffer headers.
+Half as many swap I/O buffer headers as file I/O buffers
+are allocated,
+but no more than 256.
+.SH
+System size limitations
+.PP
+As distributed, the sum of the virtual sizes of the core-resident
+processes is limited to 256M bytes.  The size of the text
+segment of a single process is currently limited to 6M bytes.
+It may be increased to no greater than the data segment size limit
+(see below) by redefining MAXTSIZ.
+This may be done with a configuration file option,
+e.g. \fBoptions MAXTSIZ="(10*1024*1024)"\fP
+to set the limit to 10 million bytes.
+Other per-process limits discussed here may be changed with similar options
+with names given in parentheses.
+Soft, user-changeable limits are set to 512K bytes for stack (DFLSSIZ)
+and 6M bytes for the data segment (DFLDSIZ) by default;
+these may be increased up to the hard limit
+with the \fIsetrlimit\fP\|(2) system call.
+The data and stack segment size hard limits are set by a system configuration
+option to one of 17M, 33M or 64M bytes.
+One of these sizes is chosen based on the definition of MAXDSIZ;
+with no option, the limit is 17M bytes; with an option
+\fBoptions MAXDSIZ="(32*1024*1024)"\fP (or any value between 17M and 33M),
+the limit is increased to 33M bytes, and values larger than 33M
+result in a limit of 64M bytes.
+You must be careful in doing this that you have adequate paging space.
+As normally configured , the system has 16M or 32M bytes per paging area,
+depending on disk size.
+The best way to get more space is to provide multiple, thereby
+interleaved, paging areas.
+Increasing the virtual memory limits results in interleaving of
+swap space in larger sections (from 500K bytes to 1M or 2M bytes).
+.PP
+By default, the virtual memory system allocates enough memory
+for system page tables mapping user page tables
+to allow 256 megabytes of simultaneous active virtual memory.
+That is, the sum of the virtual memory sizes of all (completely- or partially-)
+resident processes can not exceed this limit.
+If the limit is exceeded, some process(es) must be swapped out.
+To increase the amount of resident virtual space possible,
+you can alter the constant USRPTSIZE (in
+/sys/vax/vmparam.h).
+Each page of system page tables allows 8 megabytes of user virtual memory.
+.PP
+Because the file system block numbers are stored in
+page table \fIpg_blkno\fP
+entries, the maximum size of a file system is limited to
+2^24 1024 byte blocks.  Thus no file system can be larger than 8 gigabytes.
+.PP
+The number of mountable file systems is set at 20 by the definition
+of NMOUNT in /sys/h/param.h.
+This should be sufficient; if not, the value can be increased up to 255.
+If you have many disks, it makes sense to make some of
+them single file systems, and the paging areas don't count in this total.
+.PP
+The limit to the number of files that a process may have open simultaneously
+is set to 64.
+This limit is set by the NOFILE definition in /sys/h/param.h.
+It may be increased arbitrarily, with the caveat that the user structure
+expands by 5 bytes for each file, and thus UPAGES (/sys/vax/machparam.h)
+must be increased accordingly.
+.PP
+The amount of physical memory is currently limited to 64 Mb
+by the size of the index fields in the core-map (/sys/h/cmap.h).
+The limit may be increased by following instructions in that file
+to enlarge those fields.

+APPENDIX E. NETWORK CONFIGURATION OPTIONS
+.sp
+.R
+.NL
+.PP
+The network support in the kernel is self-configuring
+according to the protocol support options (INET and NS) and the network
+hardware discovered during autoconfiguration.
+There are several changes that may be made to customize network behavior
+due to local restrictions.
+Within the Internet protocol routines, the following options
+set in the system configuration file are supported:
+.IP \fBGATEWAY\fP
+.br
+The machine is to be used as a gateway.
+This option currently makes only minor changes.
+First, the size of the network routing hash table is increased.
+Secondly, machines that have only a single hardware network interface
+will not forward IP packets; without this option, they will also refrain
+from sending any error indication to the source of unforwardable packets.
+Gateways with only a single interface are assumed to have missing
+or broken interfaces, and will return ICMP unreachable errors to hosts
+sending them packets to be forwarded.
+.IP \fBTCP_COMPAT_42\fP
+.br
+This option forces the system to limit its initial TCP sequence numbers
+to positive numbers.
+Without this option, 4.4BSD systems may have problems with TCP connections
+to 4.2BSD systems that connect but never transfer data.
+The problem is a bug in the 4.2BSD TCP.
+.IP \fBIPFORWARDING\fP
+.br
+Normally, 4.4BSD machines with multiple network interfaces
+will forward IP packets received that should be resent to another host.
+If the line ``options IPFORWARDING="0"'' is in the system configuration
+file, IP packet forwarding will be disabled.
+.IP \fBIPSENDREDIRECTS\fP
+.br
+When forwarding IP packets, 4.4BSD IP will note when a packet is forwarded
+using the same interface on which it arrived.
+When this is noted, if the source machine is on the directly-attached
+network, an ICMP redirect is sent to the source host.
+If the packet was forwarded using a route to a host or to a subnet,
+a host redirect is sent, otherwise a network redirect is sent.
+The generation of redirects may be inhibited with the configuration
+option ``options IPSENDREDIRECTS="0".''
+.br
+.IP \fBSUBNETSARELOCAL\fP
+TCP calculates a maximum segment size to use for each connection,
+and sends no datagrams larger than that size.
+This size will be no larger than that supported on the outgoing
+interface.
+Furthermore, if the destination is not on the local network,
+the size will be no larger than 576 bytes.
+For this test, other subnets of a directly-connected subnetted
+network are considered to be local unless the line
+``options SUBNETSARELOCAL="0"'' is used in the system configuration file.
+.LP
+The following options are supported by the Xerox NS protocols:
+.IP \fBNSIP\fP
+.br
+This option allows NS IDP datagrams to be encapsulated in Internet IP
+packets for transmission to a collaborating NSIP host.
+This may be used to pass IDP packets through IP-only link layer networks.
+See
+.IR nsip (4P)
+for details.
+.IP \fBTHREEWAYSHAKE\fP
+.br
+The NS Sequenced Packet Protocol does not require a three-way handshake
+before considering a connection to be in the established state.
+(A three-way handshake consists of a connection request, an acknowledgement
+of the request along with a symmetrical opening indication,
+and then an acknowledgement of the reciprocal opening packet.)
+This option forces a three-way handshake before data may be transmitted
+on Sequenced Packet sockets.

+.Sh SYNOPSIS
+.Nm
+.Op Fl gp
+.Op Fl d Ar destdir
+.Ar SYSTEM_NAME
+.Sh DESCRIPTION
+This is the old version of the
+.Nm
+program.
+It understands the old autoconfiguration scheme
+used on the HP300, i386, DECstation, and derivative platforms.
+The new version of
+.Nm
+is used with the
+SPARC platform.
+Only the version of
+.Nm
+applicable to the architecture that you are running
+will be installed on your machine.
+.Pp
+.Nm
+builds a set of system configuration files from the file
+.Ar SYSTEM_NAME
+which describes
+the system to configure.
+A second file
+tells
+.Nm
+what files are needed to generate a system and
+can be augmented by configuration specific set of files
+that give alternate files for a specific machine
+(see the
+.Sx FILES
+section below).
+.Pp
+Available options and operands:
+.Bl -tag -width ".Ar SYSTEM_NAME"
+.It Fl d Ar destdir
+Use
+.Ar destdir
+as the output directory, instead of the default one.
+Note that
+.Nm
+does not append
+.Ar SYSTEM_NAME
+to the directory given.
+.It Fl g
+Configure a system for debugging.
+.It Fl p
+Configure a system for profiling; for example,
+.Xr kgmon 8
+and
+.Xr gprof 1 .
+If two or more
+.Fl p
+options are supplied,
+.Nm
+configures a system for high resolution profiling.
+.It Ar SYSTEM_NAME
+Specify the name of the system configuration file
+containing device specifications, configuration options
+and other system parameters for one system configuration.
+.El
+.Pp
+.Nm
+should be run from the
+.Pa conf
+subdirectory of the system source (usually
+.Pa /sys/ Ns Va ARCH Ns Pa /conf ) ,
+where
+.Va ARCH
+represents one of the architectures supported by
+.Fx .
+.Nm
+creates the directory
+.Pa ../compile/ Ns Ar SYSTEM_NAME
+or the one given with the
+.Fl d
+option
+as necessary and places all output files there.
+The output of
+.Nm
+consists of a number of files; for the
+.Tn i386 ,
+they are:
+.Pa ioconf.c ,
+a description
+of what I/O devices are attached to the system;
+.Pa Makefile ,
+used by
+.Xr make 1
+in building the system;
+header files,
+definitions of
+the number of various devices that will be compiled into the system.
+.Pp
+After running
+.Nm ,
+it is necessary to run
+.Dq Li make depend
+in the directory where the new makefile
+was created.
+.Nm
+prints a reminder of this when it completes.
+.Pp
+If any other error messages are produced by
+.Nm ,
+the problems in the configuration file should be corrected and
+.Nm
+should be run again.
+Attempts to compile a system that had configuration errors
+are likely to fail.
+.Pp
+If the
+.Cd "options INCLUDE_CONFIG_FILE"
+is used in the configuration file the
+entire input file is embedded in the new kernel.
+This means that
+.Xr strings 1
+can be used to extract it from a kernel:
+to extract the configuration information, use the command
+.Pp
+.Dl "strings kernel | grep ___"
+.Sh DEBUG KERNELS
+Traditional
+.Bx
+kernels compiled without symbols due to the heavy load on the
+system when compiling a
+.Dq debug
+kernel.
+A debug kernel contains complete symbols for all the source files, and
+enables an experienced kernel programmer to analyse the cause of a problem.
+The
+debuggers available prior to
+.Bx 4.4 Lite
+were able to find some information
+from a normal kernel;
+.Xr gdb 1
+provides very little support for normal kernels, and a debug kernel is needed
+for any meaningful analysis.
+.Pp
+For reasons of history, time and space, building a debug kernel is not the
+default with
+.Fx :
+a debug kernel takes up to 30% longer to build and
+requires about 30 MB of disk storage in the build directory, compared to about 6
+MB for a non-debug kernel.
+A debug kernel is about 11 MB in size, compared to
+about 2 MB for a non-debug kernel.
+This space is used both in the root file
+system and at run time in memory.
+Use the
+.Fl g
+option to build a debug kernel.
+With this option,
+.Nm
+causes two kernel files to be built in the kernel build directory:
+.Bl -bullet
+.It
+.Pa kernel.debug
+is the complete debug kernel.
+.It
+.Pa kernel
+is a copy of the kernel with the debug symbols stripped off.
+This is equivalent
+to the normal non-debug kernel.
+.El
+.Pp
+There is currently little sense in installing and booting from a debug kernel,
+since the only tools available which use the symbols do not run on-line.
+There
+are therefore two options for installing a debug kernel:
+.Bl -bullet
+.It
+.Dq Li "make install"
+installs
+.Pa kernel
+in the root filesystem.
+.It
+.Dq Li "make install.debug"
+installs
+.Pa kernel.debug
+in the root filesystem.

+.Dd December 20, 1993
+.Dt CRON 8
+.Os
+.Sh NAME
+.Nm cron
+.Nd daemon to execute scheduled commands (Vixie Cron)
+.Sh SYNOPSIS
+.Nm
+.Op Fl s
+.Op Fl o
+.Op Fl x Ar debugflag Ns Op , Ns Ar ...
+.Sh DESCRIPTION
+.Nm Cron
+should be started from
+.Pa /etc/rc
+or
+.Pa /etc/rc.local .
+It will return immediately,
+so you don't need to start it with '&'.
+.Pp
+.Nm Cron
+searches
+.Pa /var/cron/tabs
+for crontab files which are named after accounts in
+.Pa /etc/passwd ;
+crontabs found are loaded into memory.
+.Nm Cron
+also searches for
+.Pa /etc/crontab
+which is in a different format (see
+.Xr crontab 5 ) .
+.Nm Cron
+then wakes up every minute, examining all stored crontabs, checking each
+command to see if it should be run in the current minute.  When executing
+commands, any output is mailed to the owner of the crontab (or to the user
+named in the
+.Ev MAILTO
+environment variable in the crontab, if such exists).
+.Pp
+Additionally,
+.Nm
+checks each minute to see if its spool directory's modification time (or
+the modification time on
+.Pa /etc/crontab )
+has changed, and if it has,
+.Nm
+will then examine the modification time on all crontabs and reload those
+which have changed.  Thus
+.Nm
+need not be restarted whenever a crontab file is modified.  Note that the
+.Xr crontab 1
+command updates the modification time of the spool directory whenever it
+changes a crontab.
+.Pp
+Available options:
+.Bl -tag -width indent
+.It Fl s
+Enable special handling of situations when the GMT offset of the local
+timezone changes, such as the switches between the standard time and
+daylight saving time.
+.Pp
+The jobs run during the GMT offset changes time as
+intuitively expected.
+If a job falls into a time interval that disappears
+(for example, during the switch from
+standard time) to daylight saving time or is
+duplicated (for example, during the reverse switch), then it's handled
+in one of two ways:
+.Pp
+The first case is for the jobs that run every at hour of a time interval
+overlapping with the disappearing or duplicated interval.
+In other words, if the job had run within one hour before the GMT offset change
+(and cron was not restarted nor the
+.Xr crontab 5
+changed after that)
+or would run after the change at the next hour.
+They work as always, skip the skipped time or run in the added
+time as usual.
+.Pp
+The second case is for the jobs that run less frequently.
+They are executed exactly once, they are not skipped nor
+executed twice (unless cron is restarted or the user's
+.Xr crontab 5
+is changed during such a time interval).
+If an interval disappears
+due to the GMT offset change, such jobs are
+executed at the same absolute point of time as they would be in the
+old time zone.
+For example, if exactly one hour disappears, this
+point would be during the next hour at the first minute that is
+specified for them in
+.Xr crontab 5 .
+.It Fl o
+Disable the special handling of situations when the GMT offset of the local
+timezone changes, to be compatible with the old (default) behavior.
+If both options
+.Fl o
+and
+.Fl s
+are specified, the option specified last wins.
+.It Fl x Ar debugflag Ns Op , Ns Ar ...
+Enable writing of debugging information to standard output.
+One or more of the following comma separated
+.Ar debugflag
+identifiers must be specified:
+.Pp
+.Bl -tag -width ".Cm proc" -compact
+.It Cm bit
+currently not used
+.It Cm ext
+make the other debug flags more verbose
+.It Cm load
+be verbose when loading crontab files
+.It Cm misc
+be verbose about miscellaneous one-off events
+.It Cm pars
+be verbose about parsing individual crontab lines
+.It Cm proc
+be verbose about the state of the process, including all of its offspring
+.It Cm sch
+be verbose when iterating through the scheduling algorithms
+.It Cm test
+trace through the execution, but do not perform any actions

+.Sh SYNOPSIS
+.Nm
+.Op Fl u Ar user
+.Ar file
+.Nm
+.Op Fl u Ar user
+{
+.Fl l |
+.Fl r |
+.Fl e
+}
+.Sh DESCRIPTION
+The
+.Nm
+utility is the program used to install, deinstall or list the tables
+used to drive the
+.Xr cron 8
+daemon in Vixie Cron.  Each user can have their own crontab, and though
+these are files in
+.Pa /var ,
+they are not intended to be edited directly.
+.Pp
+If the
+.Pa allow
+file exists, then you must be listed therein in order to be allowed to use
+this command.  If the
+.Pa allow
+file does not exist but the
+.Pa deny
+file does exist, then you must
+.Em not
+be listed in the
+.Pa deny
+file in order to use this command.  If neither of these files exists, then
+depending on site-dependent configuration parameters, only the super user
+will be allowed to use this command, or all users will be able to use this
+command.
+The format of these files is one username per line,
+with no leading or trailing whitespace.
+Lines of other formats will be ignored,
+and so can be used for comments.
+.Pp
+The first form of this command is used to install a new crontab from some
+named file or standard input if the pseudo-filename ``-'' is given.
+.Pp
+The following options are available:
+.Bl -tag -width indent
+.It Fl u
+Specify the name of the user whose crontab is to be
+tweaked.  If this option is not given,
+.Nm
+examines "your" crontab, i.e., the crontab of the person executing the
+command.  Note that
+.Xr su 1
+can confuse
+.Nm
+and that if you are running inside of
+.Xr su 1
+you should always use the
+.Fl u
+option for safety's sake.
+.It Fl l
+Display the current crontab on standard output.
+.It Fl r
+Remove the current crontab.
+.It Fl e
+Edit the current crontab using the editor specified by
+the
+.Ev VISUAL
+or
+.Ev EDITOR
+environment variables.
+The specified editor
+.Em must
+edit the file in place;
+any editor that unlinks the file and recreates it cannot be used.
+After you exit
+from the editor, the modified crontab will be installed automatically.

+.Xr cron 8
+.Sh FILES
+.Bl -tag -width /var/cron/allow -compact
+.It Pa /var/cron/allow
+.It Pa /var/cron/deny
+.El
+.Sh STANDARDS
+The
+.Nm
+command conforms to
+.St -p1003.2 .
+This new command syntax
+differs from previous versions of Vixie Cron, as well as from the classic
+SVR3 syntax.
+.Sh DIAGNOSTICS
+A fairly informative usage message appears if you run it with a bad command
+line.

+.Sh NAME
+.Nm crontab
+.Nd tables for driving cron
+.Sh DESCRIPTION
+A
+.Nm
+file contains instructions to the
+.Xr cron 8
+daemon of the general form: ``run this command at this time on this date''.
+Each user has their own crontab, and commands in any given crontab will be
+executed as the user who owns the crontab.  Uucp and News will usually have
+their own crontabs, eliminating the need for explicitly running
+.Xr su 1
+as part of a cron command.
+.Pp
+Blank lines and leading spaces and tabs are ignored.  Lines whose first
+non-space character is a pound-sign (#) are comments, and are ignored.
+Note that comments are not allowed on the same line as cron commands, since
+they will be taken to be part of the command.  Similarly, comments are not
+allowed on the same line as environment variable settings.
+.Pp
+An active line in a crontab will be either an environment setting or a cron
+command.  An environment setting is of the form,
+.Bd -literal
+    name = value
+.Ed
+.Pp
+where the spaces around the equal-sign (=) are optional, and any subsequent
+non-leading spaces in
+.Em value
+will be part of the value assigned to
+.Em name .
+The
+.Em value
+string may be placed in quotes (single or double, but matching) to preserve
+leading or trailing blanks.
+The
+.Em name
+string may also be placed in quote (single or double, but matching)
+to preserve leading, traling or inner blanks.
+.Pp
+Several environment variables are set up
+automatically by the
+.Xr cron 8
+daemon.
+.Ev SHELL
+is set to
+.Pa /bin/sh ,
+and
+.Ev LOGNAME
+and
+.Ev HOME
+are set from the
+.Pa /etc/passwd
+line of the crontab's owner.
+.Ev HOME
+and
+.Ev SHELL
+may be overridden by settings in the crontab;
+.Ev LOGNAME
+may not.
+.Pp
+(Another note: the
+.Ev LOGNAME
+variable is sometimes called
+.Ev USER
+on
+.Bx
+systems...
+On these systems,
+.Ev USER
+will be set also).
+.Pp
+In addition to
+.Ev LOGNAME ,
+.Ev HOME ,
+and
+.Ev SHELL ,
+.Xr cron 8
+will look at
+.Ev MAILTO
+if it has any reason to send mail as a result of running
+commands in ``this'' crontab.  If
+.Ev MAILTO
+is defined (and non-empty), mail is
+sent to the user so named.  If
+.Ev MAILTO
+is defined but empty (MAILTO=""), no
+mail will be sent.  Otherwise mail is sent to the owner of the crontab.  This
+option is useful if you decide on
+.Pa /bin/mail
+instead of
+.Pa /usr/lib/sendmail
+as
+your mailer when you install cron --
+.Pa /bin/mail
+doesn't do aliasing, and UUCP
+usually doesn't read its mail.
+.Pp
+The format of a cron command is very much the V7 standard, with a number of
+upward-compatible extensions.  Each line has five time and date fields,
+followed by a user name
+(with optional ``:<group>'' and ``/<login-class>'' suffixes)
+if this is the system crontab file,
+followed by a command.  Commands are executed by
+.Xr cron 8
+when the minute, hour, and month of year fields match the current time,
+.Em and
+when at least one of the two day fields (day of month, or day of week)
+matches the current time (see ``Note'' below).
+.Xr cron 8
+examines cron entries once every minute.
+The time and date fields are:
+.Bd -literal -offset indent
+field         allowed values
+-----         --------------
+minute        0-59
+hour          0-23
+day of month  1-31
+month         1-12 (or names, see below)
+day of week   0-7 (0 or 7 is Sun, or use names)
+.Ed
+.Pp
+A field may be an asterisk (*), which always stands for ``first\-last''.
+.Pp
+Ranges of numbers are allowed.  Ranges are two numbers separated
+with a hyphen.  The specified range is inclusive.  For example,
+8-11 for an ``hours'' entry specifies execution at hours 8, 9, 10
+and 11.
+.Pp
+Lists are allowed.  A list is a set of numbers (or ranges)
+separated by commas.  Examples: ``1,2,5,9'', ``0-4,8-12''.
+.Pp
+Step values can be used in conjunction with ranges.  Following
+a range with ``/<number>'' specifies skips of the number's value
+through the range.  For example, ``0-23/2'' can be used in the hours
+field to specify command execution every other hour (the alternative
+in the V7 standard is ``0,2,4,6,8,10,12,14,16,18,20,22'').  Steps are
+also permitted after an asterisk, so if you want to say ``every two
+hours'', just use ``*/2''.
+.Pp
+Names can also be used for the ``month'' and ``day of week''
+fields.  Use the first three letters of the particular
+day or month (case doesn't matter).  Ranges or
+lists of names are not allowed.
+.Pp
+The ``sixth'' field (the rest of the line) specifies the command to be
+run.
+The entire command portion of the line, up to a newline or %
+character, will be executed by
+.Pa /bin/sh
+or by the shell
+specified in the
+.Ev SHELL
+variable of the cronfile.
+Percent-signs (%) in the command, unless escaped with backslash
+(\\), will be changed into newline characters, and all data
+after the first % will be sent to the command as standard
+input.
+.Pp
+Note: The day of a command's execution can be specified by two
+fields \(em day of month, and day of week.  If both fields are
+restricted (ie, aren't *), the command will be run when
+.Em either
+field matches the current time.  For example,
+``30 4 1,15 * 5''
+would cause a command to be run at 4:30 am on the 1st and 15th of each
+month, plus every Friday.
+.Pp
+Instead of the first five fields,
+one of eight special strings may appear:
+.Bd -literal -offset indent
+string		meaning
+------		-------
+@reboot		Run once, at startup.
+@yearly		Run once a year, "0 0 1 1 *".
+@annually	(same as @yearly)
+@monthly	Run once a month, "0 0 1 * *".
+@weekly		Run once a week, "0 0 * * 0".
+@daily		Run once a day, "0 0 * * *".
+@midnight	(same as @daily)
+@hourly		Run once an hour, "0 * * * *".
+.Ed
+.Sh EXAMPLE CRON FILE

+5 4 * * sun     echo "run at 5 after 4 every sunday"
+.Ed
+.Sh SEE ALSO
+.Xr crontab 1 ,
+.Xr cron 8
+.Sh EXTENSIONS
+When specifying day of week, both day 0 and day 7 will be considered Sunday.
+.Bx
+and
+.Tn ATT
+seem to disagree about this.
+.Pp
+Lists and ranges are allowed to co-exist in the same field.  "1-3,7-9" would
+be rejected by
+.Tn ATT
+or
+.Bx
+cron -- they want to see "1-3" or "7,8,9" ONLY.
+.Pp
+Ranges can include "steps", so "1-9/2" is the same as "1,3,5,7,9".
+.Pp
+Names of months or days of the week can be specified by name.
+.Pp
+Environment variables can be set in the crontab.  In
+.Bx
+or
+.Tn ATT ,
+the
+environment handed to child processes is basically the one from
+.Pa /etc/rc .
+.Pp
+Command output is mailed to the crontab owner
+.No ( Bx
+can't do this), can be
+mailed to a person other than the crontab owner (SysV can't do this), or the
+feature can be turned off and no mail will be sent at all (SysV can't do this
+either).
+.Pp
+All of the
+.Sq @
+commands that can appear in place of the first five fields
+are extensions.

+.Sh BUGS
+If you're in one of the 70-odd countries that observe Daylight
+Savings Time, jobs scheduled during the rollback or advance will be
+affected.  In general, it's not a good idea to schedule jobs during
+this period.
+.Pp
+For US timezones (except parts of IN, AZ, and HI) the time shift occurs at
+2AM local time.  For others, the output of the
+.Xr zdump 8
+program's verbose
+.Fl ( v )
+option can be used to determine the moment of time shift.

+Vixie Cron		Changes from V2 to V3
+Paul Vixie
+29-Dec-1993
+
+The crontab command now conforms to POSIX 1003.2.  This means that when you
+install it, if you have any "crontab" command lines floating around in shell
+scripts (such as /etc/rc or /etc/rc.local), you will need to change them.
+
+I have integrated several changes made by BSDi for their BSD/386 operating
+system; these were offerred to me before I started consulting for them, so
+it is safe to say that they were intended for publication.  Most notably,
+the name of the cron daemon has changed from "crond" to "cron".  This was
+done for compatibility with 4.3BSD.  Another change made for the same reason
+is the ability to read in an /etc/crontab file which has an extra field in
+each entry, between the time fields and the command.  This field is a user
+name, and it permits the /etc/crontab command to contain commands which are
+to be run by any user on the system.  /etc/crontab is not "installed" via
+the crontab(1) command; it is automatically read at startup time and it will
+be reread whenever it changes.
+
+I also added a "-e" option to crontab(1).  Nine people also sent me diffs
+to add this option, but I had already implemented it on my own.  I actually
+released an interrim version (V2.2, I think) for limited testing, and got a
+chance to fix a bad security bug in the "-e" option thanks to XXX.
+
+The daemon used to be extraordinarily sloppy in its use of file descriptors.
+A heck of a lot of them were left open in spawned jobs, which caused problems
+for the daemon and also caused problems with the spawned jobs if they were 
+shell scripts since "sh" and "csh" have traditionally used hidden file
+descriptors to pass information to subshells, and cron was causing them to
+think they were subshells.  If you had trouble with "sh" or "csh" scripts in
+V2, chances are good that V3 will fix your problems.
+
+About a dozen people have reminded me that I forgot to initialize
+"crontab_fd" in database.c.  Keith Cantrell was the first, so he gets the
+point.
+
+Steve Simmons reminded me that once an account has been deleted from the
+system, "crontab -u USER -d" will not work.  My solution is to suggest to
+all of you that before you delete a user's account, you first delete that
+user's crontab file if any.  From cron's point of view, usernames can never
+be treated as arbitrary strings.  Either they are valid user names, or they
+are not.  I will not make an exception for the "-d" case, for security
+reasons that I consider reasonable.  It is trivial for a root user to delete
+the entry by hand if necessary.
+
+Dan O'Neil reminded me that I forgot to reset "log_fd" in misc.c.  A lot of
+others also reminded me of this, but Dan gets the point.  I didn't fix it
+there, since the real bug was that it should have been open in the parent.
+
+Peter Kabal reminded me that I forgot to "#ifdef DEBUGGING" some code in
+misc.c.  Hans Trompert actually told me first, but Peter sent the patch so
+he gets the point.
+
+Russell Nelson told me that I'd forgotten to "#include <syslog.h>" in misc.c,
+which explains why a lot of other people complained that it wasn't using
+syslog even when they configured it that way :-).  Steve Simmons told me
+first, though, so he gets the point.
+
+An interrim version of the daemon tried to "stat" every file before
+executing it; this turned out to be a horribly bad idea since finding the
+name of a file from a shell command is a hard job (that's why we have
+shells, right?)  I removed this bogus code.  Dave Burgess gets the point.
+
+Dennis R. Conley sent a suggestion for MMDF systems, which I've added to the
+comments in cron.h.
+
+Mike Heisler noted that I use comments in the CONVERSION file which are
+documented as illegal in the man pages.  Thanks, Mike.
+
+Irving Wolfe sent me some very cheerful changes for a NeXT system, but I
+consider the system itself broken and I can't bring myself to #ifdef for
+something as screwed up as this system seems to be.  However, various others
+did send me smaller patches which appear to have cause cron to build and run
+correctly on (the latest) NeXT machines, with or without the "-posix" CFLAG.
+Irving also asked for a per-job MAILTO, and this was finally added later when
+I integrated the BSD/386 changes contributed by BSDi, and generalized some of
+the parsing.
+
+Lots of folks complained that the autogenerated "Date:" header wasn't in
+ARPA format.  I didn't understand this -- either folks will use Sendmail and
+not generate a Date:  at all (since Sendmail will do it), or folks will use
+something other than Sendmail which won't care about Date: formats.  But
+I've "fixed" it anyway...
+
+Several people suggested that "*" should be able to take a "/step".  One person
+suggested that "N/step" ought to mean "N-last/step", but that's stretching things
+a bit far.  "*/step" seems quite intuitive to me, so I've added it.  Colin Plumb
+sent in the first and most polite request for this feature.
+
+As with every release of Cron, BIND, and seemingly everything else I do, one
+user stands out with the most critical but also the most useful analysis.
+Cron V3's high score belongs to Peter Holzer, who sent in the nicest looking
+patch for the "%" interpretation problem and also helped me understand a
+tricky bit of badness in the "log_fd" problem.
+
+agulbra@flode.nvg.unit.no wins the honors for being the first to point out the
+nasty security hole in "crontab -r".  'Nuff said.
+
+Several folks pointed out that log_it() needed to exist even if logging was
+disabled.  Some day I will create a tool that will compile a subsystem with
+every possible combination and permutation of #ifdef options, but meanwhile
+thanks to everybody.
+
+job_runqueue() was using storage after freeing it, since Jordan told me back
+in 1983 that C let you do that, and I believed him in 1986 when I wrote all
+this junk.  Linux was the first to die from this error, and the Linux people
+sent me the most amazing, um, collection of patches for this problem.  Thanks
+for all the fish.
+
+Jeremy Bettis reminded me that popen() isn't safe.  I grabbed Ken Arnold's 
+version of popen/pclose from the ftpd and hacked it to taste.  We're safe now,
+from this at least.
+
+Branko Lankester sent me a very timely and helpful fix for a looming security
+problem in my "crontab -e" implementation.

+
+Vixie Cron		Changes from V1 to V2
+Paul Vixie
+8-Feb-1988
+
+Many changes were made in a rash of activity about six months ago, the exact
+list of which is no longer clear in my memory.  I know that V1 used a file
+called POKECRON in /usr/spool/cron to tell it that it was time to re-read
+all the crontab files; V2 uses the modtime the crontab directory as a flag to
+check out the crontab files; those whose modtime has changed will be re-read,
+and the others left alone.  Note that the crontab(1) command will do a utimes
+call to make sure the mtime of the dir changes, since the filename/inode will
+often remain the same after a replacement and the mtime wouldn't change in
+that case.
+
+8-Feb-88: made it possible to use much larger environment variable strings.
+	V1 allowed 100 characters; V2 allows 1000.  This was needed for PATH
+	variables on some systems.  Thanks to Toerless Eckert for this idea.
+	E-mail: UUCP: ...pyramid!fauern!faui10!eckert
+
+16-Feb-88: added allow/deny, moved /usr/spool/cron/crontabs to
+	/usr/lib/cron/tabs.  allow and deny are /usr/lib/cron/{allow,deny},
+	since the sysv naming for this depends on 'at' using the same
+	dir, which would be stupid (hint: use /usr/{lib,spool}/at).
+
+22-Feb-88: made it read the spool directory for crontabs and look each one
+	up using getpwnam() rather than reading all passwds with getpwent()
+	and trying to open each crontab.
+
+9-Dec-88: made it sync to :00 after the minute, makes cron predictable.
+	added logging to /var/cron/log.
+
+14-Apr-90: (actually, changes since December 1989)
+	fixed a number of bugs reported from the net and from John Gilmore.
+	added syslog per Keith Bostic.  security features including not
+	being willing to run a command owned or writable by other than
+	the owner of the crontab 9not working well yet)

+$FreeBSD$
+
+Conversion of BSD 4.[23] crontab files:
+
+Edit your current crontab (/usr/lib/crontab) into little pieces, with each
+users' commands in a different file.  This is different on 4.2 and 4.3,
+but I'll get to that below.  The biggest feature of this cron is that you
+can move 'news' and 'uucp' cron commands into files owned and maintainable
+by those two users.  You also get to rip all the fancy 'su' footwork out
+of the cron commands.  On 4.3, there's no need for the 'su' stuff since the
+user name appears on each command -- but I'd still rather have separate
+crontabs with separate environments and so on.
+
+Leave the original /usr/lib/crontab!  This cron doesn't use it, so you may
+as well keep it around for a while in case something goes wakko with this
+fancy version.
+
+Most commands in most crontabs are run by root, have to run by root, and
+should continue to be run by root.  They still have to be in their own file;
+I recommend /etc/crontab.src or /usr/adm/crontab.src.
+
+'uucp's commands need their own file; how about /usr/lib/uucp/crontab.src?
+'news' also, perhaps in /usr/lib/news/crontab.src...
+
+I say `how about' and `perhaps' because it really doesn't matter to anyone
+(except you) where you put the crontab source files.  The `crontab' command
+COPIES them into a protected directory (CRONDIR/SPOOL_DIR in cron.h), named
+after the user whose crontab it is.  If you want to examine, replace, or
+delete a crontab, the `crontab' command does all of those things.  The
+various `crontab.src' (my suggested name for them) files are just source
+files---they have to be copied to SPOOLDIR using `crontab' before they'll be
+executed.
+
+On 4.2, your crontab might have a few lines like this:
+
+	5 * * * *   su uucp < /usr/lib/uucp/uudemon.hr
+	10 4 * * *  su uucp < /usr/lib/uucp/uudemon.day
+	15 5 * * 0  su uucp < /usr/lib/uucp/uudemon.wk
+
+...or like this:
+
+	5 * * * *   echo /usr/lib/uucp/uudemon.hr | su uucp
+	10 4 * * *  echo /usr/lib/uucp/uudemon.day | su uucp
+	15 5 * * 0  echo /usr/lib/uucp/uudemon.wk | su uucp
+
+On 4.3, they'd look a little bit better, but not much:
+
+	5 * * * *   uucp  /usr/lib/uucp/uudemon.hr
+	10 4 * * *  uucp  /usr/lib/uucp/uudemon.day
+	15 5 * * 0  uucp  /usr/lib/uucp/uudemon.wk
+
+For this cron, you'd create /usr/lib/uucp/crontab.src (or wherever you want
+to keep uucp's commands) which would look like this:
+
+	# /usr/lib/uucp/crontab.src - uucp's crontab
+	#
+	PATH=/usr/lib/uucp:/bin:/usr/bin
+	SHELL=/bin/sh
+	HOME=/usr/lib/uucp
+	#
+	5 * * * *   uudemon.hr
+	10 4 * * *  uudemon.day
+	15 5 * * 0  uudemon.wk
+
+The application to the `news' cron commands (if any) is left for you to
+figure out.  Likewise if there are any other cruddy-looking 'su' commands in
+your crontab commands, you don't need them anymore: just find a good place
+to put the `crontab.src' (or whatever you want to call it) file for that
+user, put the cron commands into it, and install it using the `crontab'
+command (probably with "-u USERNAME", but see the man page).
+
+If you run a 4.2-derived cron, you could of course just install your current
+crontab in toto as root's crontab.  It would work exactly the way your
+current one does, barring the extra steps in installing or changing it.
+There would still be advantages to this cron, mostly that you get mail if
+there is any output from your cron commands.
+
+One note about getting mail from cron: you will probably find, after you
+install this version of cron, that your cron commands are generating a lot
+of irritating output.  The work-around for this is to redirect all EXPECTED
+output to a per-execution log file, which you can examine if you want to
+see the output from the "last time" a command was executed; if you get any
+UNEXPECTED output, it will be mailed to you.  This takes a while to get
+right, but it's amazingly convenient.  Trust me.

+
+--	Months can likewise be specified by name.  Three letters only.
+
+--	Ranges and lists can be mixed.  Standard crons won't allow '1,3-5'.
+
+--	Ranges can specify 'step' values.  '10-16/2' is like '10,12,14,16'.
+
+--	Sunday is both day 0 and day 7 -- apparently BSD and ATT disagree
+	about this.
+
+--	Each user gets their own crontab file.  This is a win over BSD 4.2,
+	where only root has one, and over BSD 4.3, where they made the crontab
+	format incompatible and although the commands can be run by non-root
+	uid's, root is still the only one who can edit the crontab file.  This
+	feature mimics the SysV cron.
+
+--	The 'crontab' command is loosely compatible with SysV, but has more
+	options which just generally make more sense.  Running crontab with
+	no arguments will print a cute little summary of the command syntax.
+
+--	Comments and blank lines are allowed in the crontab file.  Comments
+	must be on a line by themselves; leading whitespace is ignored, and
+	a '#' introduces the comment.
+
+--	(big win) If the `crontab' command changes anything in any crontab,
+	the 'cron' daemon will reload all the tables before running the
+	next iteration.  In some crons, you have to kill and restart the
+	daemon whenever you change a crontab.  In other crons, the crontab
+	file is reread and reparsed every minute even if it didn't change.
+
+--	In order to support the automatic reload, the crontab files are not
+	readable or writable except by 'crontab' or 'cron'.  This is not a
+	problem, since 'crontab' will let you do pretty much whatever you
+	want to your own crontab, or if you are root, to anybody's crontab.
+
+--	If any output is generated by a command (on stdout OR stderr), it will
+	be mailed to the owner of the crontab that contained the command (or
+	MAILTO, see discussion of environment variables, above).  The headers
+	of the mail message will include the command that was run, and a
+	complete list of the environment that was passed to it, which will
+	contain (at least) the USER (LOGNAME on SysV), HOME, and SHELL.
+
+--	the dom/dow situation is odd.  '* * 1,15 * Sun' will run on the
+	first and fifteenth AND every Sunday;  '* * * * Sun' will run *only*
+	on Sundays;  '* * 1,15 * *' will run *only* the 1st and 15th.  this
+	is why we keep 'e->dow_star' and 'e->dom_star'.  I didn't think up
+	this behaviour; it's how cron has always worked but the documentation
+	hasn't been very clear.  I have been told that some AT&T crons do not
+	act this way and do the more reasonable thing, which is (IMHO) to "or"
+	the various field-matches together.  In that sense this cron may not
+	be completely similar to some AT&T crons.

+Read the comments at the top of the Makefile, then edit the area marked
+'configurable stuff'.
+
+Edit config.h.  The stuff I expect you to change is down a bit from the
+top of the file, but it's clearly marked.  Also look at pathnames.h.
+
+You don't have to create the /var/cron or /var/cron/tabs directories, since
+both the daemon and the `crontab' program will do this the first time they
+run if they don't exist.  You do need to have a /var, though -- just "mkdir
+/var" if you don't have one, or you can "mkdir /usr/var; ln -s /usr/var /var"
+if you expect your /var to have a lot of stuff in it.
+
+You will also need /usr/local/etc and /usr/local/bin directories unless you
+change the Makefile.  These will have to be created by hand, but if you are
+a long-time Usenet user you probably have them already.  /usr/local/man is
+where I keep my man pages, but I have the source for `man' and you probably
+do not.  Therefore you may have to put the man pages into /usr/man/manl,
+which will be hard since there will be name collisions.  (Note that the man
+command was originally written by Bill Joy before he left Berkeley, and it
+contains no AT&T code, so it is in UUNET's archive of freely-distributable
+BSD code.)
+
+LINUX note: /usr/include/paths.h on some linux systems shows _PATH_SENDMAIL
+	to be /usr/bin/sendmail even though sendmail is installed in /usr/lib.
+	you should check this out.
+
+say:
+	make all
+
+su and say:
+	make install
+
+Note that if I can get you to "su and say" something just by asking, you have
+a very serious security problem on your system and you should look into it.
+
+Edit your /usr/lib/crontab file into little pieces -- see the CONVERSION file
+for help on this.
+
+Use the `crontab' command to install all the little pieces you just created.
+Some examples (see below before trying any of these!)
+
+	crontab -u uucp -r /usr/lib/uucp/crontab.src
+	crontab -u news -r /usr/lib/news/crontab.src
+	crontab -u root -r /usr/adm/crontab.src
+
+Notes on above examples: (1) the .src files are copied at the time the
+command is issued; changing the source files later will have no effect until
+they are reinstalled with another `crontab -r' command.  (2) The crontab
+command will affect the crontab of the person using the command unless `-u
+USER' is given; `-u' only works for root.  When using most `su' commands
+under most BSD's, `crontab' will still think of you as yourself even though
+you may think of yourself as root -- so use `-u' liberally.  (3) the `-r'
+option stands for `replace'; check the man page for crontab(1) for other
+possibilities.
+
+Kill your existing cron daemon -- do `ps aux' and look for /etc/cron.
+
+Edit your /etc/rc or /etc/rc.local, looking for the line that starts up
+/etc/cron.  Comment it out and add a line to start the new cron daemon
+-- usually /usr/local/etc/cron, unless you changed it in the Makefile.
+
+Start up this cron daemon yourself as root.  Just type /usr/local/etc/cron
+(or whatever); no '&' is needed since the daemon forks itself and the
+process you executed returns immediately.
+
+ATT notes: for those people unfortunate enough to be stuck on a AT&T UNIX,
+you will need the public-domain "libndir", found in the B News source and in
+any comp.sources.unix archive.  You will also need to hack the code some.

+One of the limitations of the present versions of cron is the lack

+
+One problem that has always plagued me with cron is the assumed ORing.
+I'd like to see some type of ANDing implemented.  I guess I can best
+describe this by example.  Say I have the following line in my crontab
+file:
+
+*  *  4-31  *  1-6	/usr/bin/command
+
+What this does is run 'command' on the 4th thru 31st days of the
+month, AND on Monday thru Saturday; which probably means running it
+every day of the month (unless Sunday falls on days 1-3).  This
+happens because cron runs the command if the day-of-month OR the
+day-of-week is true.
+
+What I'd like to happen with the above line is to run the command ONLY
+on Monday thru Saturday any time after the 3rd of the month, e.g. if
+the day-of-month AND the day-of-week are true.
+
+My proposal to you is to implement some special chars for the first
+five fields.  Examples:
+
+*  *  !1-3  *  1-6	/usr/bin/command
+
+(run command Mon-Sat, but NOT [!] on the first 3 days of the month)
+
+*  *  &4-31 *  &1-6	/usr/bin/command
+
+(run command if day-of-month AND day-of-week are true)
+
+Get the picture?  This would be compatable with existing versions of
+cron (which wouldn't currently be using any special characters, so
+that old crontabs would be handled correctly).
+
+<<	This message made me aware of the actual boolean expression involved
+	in a crontab entry.  I'd assumed that it was
+		(minute && hour && DoM && month && DoW)
+	But it's really
+		(minute && hour && month && (DoM || DoW))
+
+	I can see some value in changing this, but with a fixed order of
+	fields, operators get to be kindof unary, which && and || really
+	aren't.  If someone has an idea on a syntax that allows useful
+	variations to the standard (&& && && (||)) default, please suggest. >>

+
+Yes!!!  There are several critical failures in System V cron...
+
+1. Pass all variables in cron's environment into the environment of things
+   cron starts up, or at least into the crontab entries started up (at jobs
+   will inherit the environment of the user).  If nothing else it is critically
+   important that the TZ variable be passed on.  PATH should be passed on too.
+   Basically, passing environment values allows one to design a standard
+   environment with TZ and PATH and have that run by everything.  If anyone
+   tells you this is no big deal, consider what happens when uucico is
+   started by cron in CA to make a long distance phone link...  Unless the
+   administrator is really on his/her toes, calls scheduled at 5pm will really
+   go at two in the afternoon, needlessly incurring huge phone bills, all
+   because System V refuses to pass the TZ from its environment down.  There
+   are work arounds, but only putting it in cron will really work.  This is
+   not a security hole.
+
+<<	delete TERM and TERMCAP; modify HOME, USER, and CWD; pass TZ and
+	PATH through undisturbed.  any other requests out there?
+
+	BSD doesn't have this problem -- TZ is passed right on through if
+	you define it in the shell before starting my cron daemon.  However,
+	the BSD I'm running this on doesn't need TZ to be defined anyway...
+	The default in the kernel has been just fine so far...  But just the
+	same, if/when I port to SysV (I guess I really should), I'll make
+	sure this works right.
+
+	I guess I've been spoiled.  HPUX is SysV-based, and I never had a
+	problem with cron and TZ when I used it.			  >>
+
+2. A way to avoid logging stuff in /usr/lib/cron/log.  I have a cron entry
+   run uudemon.hr every 10 minutes.  This is 144 times/day.  Each run generates
+   three lines of text, for a total of 432 lines of text I don't want to see.
+   Obviously this should be optional, but it would be nice if there were a
+   way to flag an entry so that it wasn't logged at all unless there was an
+   error.

+The other problem you have is making sure you can run standard
+crontabs.  I would suggest something like this: if the command part of the
+entry starts with an unescaped -, then flags and options follow immediately
+thereafter.  As in:
+
+2,12,22,32,42,52 * * * * -q /usr/lib/uucp/uudemon.hr
+
+This could mean do not log the uudemon.hr run unless there is a problem of
+some kind.  This is probably safe as not many filenames start with "-", and
+those that do are already a problem for people.
+
+<<	Since I don't plan on supporting /usr/lib/cron/log in ANY form unless
+	many people request it, I won't be needing -q as you've defined it.
+	I could use something like this to avoid sending mail on errors, for
+	the occasional script that you don't want to bullet-proof.
+
+	The compatibility issue is CRITICAL.  The 4.3BSD crontab format is
+	a crime against the whole philosophy of Unix(TM), in my opinion.   >>
+
+One other minor thing to consider is the ulimit: can different users get
+different ulimits for their crontab entries?
+
+<<	Boy I'm ignorant today.  What's a ulimit, and what should I do with
+	it in a crontab?  Suggestions, enlightenment, etc ??		   >>

+
+The System V cron is nice, but it has a few annoying features.  One is that
+its mail files will say that the previous message is the output of "one of your
+cron commands."  I wish it would say WHICH cron commmand.
+
+<<	Done.  Also which shell, which user (useful when the mail gets
+	forwarded), which home directory, and other useful crud.	>>
+
+Another problem is with timezones.  It is necessary to specify TZ=PST8PDT (or
+whatever) when you invoke cron (from inittab, or /etc/rc) and it is also
+necessary to add TZ=PST8PDT to each crontab line which might need it.  Cron
+should automatically export its idea of the "TZ" to each invoked command, and
+it should be possible to put a line in the crontab file which overrides that
+for every command in the file (e.g., most users are on EST, so cron is run
+with TZ=EST5EDT; but one user is usually on PST and wants all of his cron
+commands to run with TZ=PST8PDT).  This might be extended to allow any
+environment variable to be specified once for the whole crontab file (e.g.,
+PATH).
+
+<<	Well, since I run the user's shell, you could put this into .cshrc.
+	generic environment-variable setting could be useful, though.  Since
+	I have to modify the environment anyway, I'll consider this.	  >>
+
+A log file might be a nice idea, but the System V cron log is too verbose.
+I seem to remember that cron keeps it open, too; so you can't even have
+something go and periodically clean it out.

+Vixie Cron V3.0
+December 27, 1993
+[V2.2 was some time in 1992]
+[V2.1 was May 29, 1991]
+[V2.0 was July 5, 1990]
+[V2.0-beta was December 9, 1988]
+[V1.0 was May 6, 1987]
+Paul Vixie
+
+This is a version of 'cron' that is known to run on BSD 4.[23] systems.  It
+is functionally based on the SysV cron, which means that each user can have
+their own crontab file (all crontab files are stored in a read-protected
+directory, usually /var/cron/tabs).  No direct support is provided for
+'at'; you can continue to run 'atrun' from the crontab as you have been
+doing.  If you don't have atrun (i.e., System V) you are in trouble.
+
+A messages is logged each time a command is executed; also, the files
+"allow" and "deny" in /var/cron can be used to control access to the
+"crontab" command (which installs crontabs).  It hasn't been tested on
+SysV, although some effort has gone into making the port an easy one.
+
+This is more or less the copyright that USENET contributed software usually
+has.  Since ATT couldn't use this version if they had to freely distribute
+source, and since I'd love to see them use it, I'll offer some rediculously
+low license fee just to have them take it.  In the unlikely event that they
+do this, I will continue to support and distribute the pseudo-PD version, so
+please, don't flame me for wanting my work to see a wider distribution.
+
+To use this: Sorry, folks, there is no cutesy 'Configure' script.  You'll
+have to go edit a couple of files... So, here's the checklist:
+
+	Read all the FEATURES, INSTALL, and CONVERSION files
+	Edit config.h
+	Edit Makefile
+		(both of these files have instructions inside; note that
+		 some things in config.h are definable in Makefile and are
+		 therefore surrounded by #ifndef...#endif)
+	'make'
+	'su' and 'make install'
+		(you may have to install the man pages by hand)
+	kill your existing cron process
+		(actually you can run your existing cron if you want, but why?)
+	build new crontabs using /usr/lib/{crontab,crontab.local}
+		(either put them all in "root"'s crontab, or divide it up
+		 and rip out all the 'su' commands, collapse the lengthy
+		 lists into ranges with steps -- basically, this step is
+		 as much work as you want to make it)
+	start up the new cron
+		(must be done as root)
+	watch it. test it with 'crontab -r' and watch the daemon track your
+		changes.
+	if you like it, change your /etc/{rc,rc.local} to use it instead of
+		the old one.

+Many people have contributed to cron.  Many more than I can remember, in fact.
+Rich Salz and Carl Gutekunst were each of enormous help to me in V1; Carl for
+helping me understand UNIX well enough to write it, and Rich for helping me
+get the features right.
+
+John Gilmore wrote me a wonderful review of V2, which took me a whole year to
+answer even though it made me clean up some really awful things in the code.
+(According to John the most awful things are still in here, of course.)
+
+Paul Close made a suggestion which led to /etc/crond.pid and the mutex locking
+on it.  Kevin Braunsdorf of Purdue made a suggestion that led to @reboot and
+its brothers and sisters; he also sent some diffs that lead cron toward compil-
+ability with System V, though without at(1) capabilities, this cron isn't going
+to be that useful on System V.  Bob Alverson fixed a silly bug in the line
+number counting.  Brian Reid made suggestions which led to the run queue and
+the source-file labelling in installed crontabs.
+
+Scott Narveson ported V2 to a Sequent, and sent in the most useful single batch
+of diffs I got from anybody.  Changes attributable to Scott are:
+	-> sendmail won't time out if the command is slow to generate output
+	-> day-of-week names aren't off by one anymore
+	-> crontab says the right thing if you do something you shouldn't do
+	-> crontab(5) man page is longer and more informative
+	-> misc changes related to the side effects of fclose()
+	-> Sequent "universe" support added (may also help on Pyramids)
+	-> null pw_shell is dealt with now; default is /bin/sh

+CRUNCH 0.2 README				6/14/94
+
+Crunch is available via anonymous ftp to ftp.cs.umd.edu in
+		pub/bsd/crunch-0.2.tar.gz
+
+
+WHAT'S NEW IN 0.2
+
+* The prototype awk script has been replaced by a more capable and
+  hopefully more robust C program.
+* No fragile template makefiles or dependencies on the details of the
+  bsd build environment.
+* You can build crunched binaries even with no sources on-line, you
+  just need the .o files.  Crunchgen still will try to figure out as
+  much as possible on its own, but you can override its guessing by
+  specifying the list of .o files explicitly.
+* Crunch itself has been bmake'd and some man pages written, so it
+  should be ready to install.
+
+
+INTRODUCTION
+
+Crunch is a little package that helps create "crunched" binaries for use
+on boot, install, and fixit floppies.  A crunched binary in this case is
+one where many programs have been linked together into one a.out file.
+The different programs are run depending on the value of argv[0], so
+hard links to the crunched binary suffice to simulate a perfectly normal
+system.
+
+As an example, I have created an 980K crunched "fixit" binary containing
+the following programs in their entirety:
+
+	cat chmod cp date dd df echo ed expr hostname kill ln ls mkdir
+	mt mv pwd rcp rm rmdir sh sleep stty sync test [ badsect chown
+	clri disklabel dump rdump dmesg fdisk fsck halt ifconfig init
+	mknod mount newfs ping reboot restore rrestore swapon umount
+	ftp rsh sed telnet rlogin vi cpio gzip gunzip gzcat
+
+Note carefully: vi, cpio, gzip, ed, sed, dump/restore, some networking
+utilities, and the disk management utilities, all in a binary small
+enough to fit on a 1.2 MB root filesystem floppy (albeit with the kernel
+on its own boot floppy).  A more reasonable subset can be made to fit
+easily with a kernel for a decent one-disk fixit filesystem.
+
+The linking together of different programs by hand is an old
+space-saving technique.  Crunch automates the process by building the
+necessary stub files and makefile for you (via the crunchgen program),
+and by doctoring the symbol tables of the component .o files to allow
+them to link without "symbol multiply defined" conflicts (via the
+crunchide program).
+
+
+BUILDING CRUNCH
+
+Just type make, then make install.
+
+Crunch was written and tested under NetBSD/i386, but should work under
+other PC BSD systems that use GNU ld.
+
+The crunchgen(1) and crunchide(1) man pages have more details on using
+crunch, and the examples subdirectory contains some working .conf files
+and a sample Makefile.
+
+CREDITS
+
+Thanks to the NetBSD team for a consistently high quality effort in
+bringing together a solid, state of the art development environment.
+
+Thanks to the FreeBSD guys; Rod Grimes, Nate Williams and Jordan
+Hubbard; and to Bruce Evans, for immediate and detailed feedback on
+crunch 0.1, and for pressing me to make the prototype more useable.
+
+Crunch was written for the Maruti Hard Real-Time Operating System
+project at the University of Maryland, to help make for better install
+and recovery procedures for our NetBSD-based development environment. It
+is copyright (c) 1994 by the University of Maryland under a UCB-style
+freely- redistributable notice.  See the file COPYRIGHT for details.
+
+Please let me know of any problems or of enhancements you make to this
+package.  I'm particularly interested in the details of what you found
+was good to put on your fixit or install disks.  Thanks!
+
+Share and Enjoy,
+Jaime

+.Sh DESCRIPTION
+A crunched binary is a program made up of many other programs linked
+together into a single executable.
+The crunched binary
+.Fn main
+function determines which component program to run by the contents of
+.Va argv[0] .
+The main reason to crunch programs together is for fitting
+as many programs as possible onto an installation or system recovery
+floppy.
+.Pp
+The
+.Nm
+utility reads in the specifications in
+.Ar conf-file
+for a crunched binary, and generates a
+.Pa Makefile
+and accompanying
+top-level C source file that when built creates the crunched executable
+file from the component programs.
+For each component program,
+.Nm
+can optionally attempt to determine the object (.o) files that make up
+the program from its source directory
+.Pa Makefile .
+This information is cached between runs.
+The
+.Nm
+utility uses the companion program
+.Xr crunchide 1
+to eliminate link-time conflicts between the component programs by
+hiding all unnecessary symbols.
+.Pp
+The
+.Nm
+utility places specific requirements on package
+.Pa Makefile Ns s
+which make it unsuitable for use with
+.No non- Ns Bx
+sources.
+In particular, the
+.Pa Makefile
+must contain the target
+.Ic depend ,
+and it must define all object files in the variable
+.Va OBJS .
+In some cases, you can use a fake
+.Pa Makefile :
+before looking for
+.Pa Makefile
+in the source directory
+.Pa foo ,
+.Nm
+looks for the file
+.Pa Makefile.foo
+in the current directory.
+.Pp
+After
+.Nm
+is run, the crunched binary can be built by running
+.Dq Li make -f <conf-name>.mk .
+The component programs' object files must already be built.
+An
+.Ic objs
+target, included in the output makefile, will
+run
+.Xr make 1
+in each component program's source dir to build the object
+files for the user.
+This is not done automatically since in release
+engineering circumstances it is generally not desirable to be
+modifying objects in other directories.
+.Pp
+The options are as follows:
+.Bl -tag -width indent
+.It Fl c Ar c-file-name
+Set output C file name to
+.Ar c-file-name .
+The default name is
+.Pa <conf-name>.c .
+.It Fl e Ar exec-file-name
+Set crunched binary executable file name to
+.Ar exec-file-name .
+The default name is
+.Pa <conf-name> .
+.It Fl f
+Flush cache.
+Forces the recalculation of cached parameters.
+.It Fl l
+List names.
+Lists the names this binary will respond to.
+.It Fl h Ar makefile-header-name
+Set the name of a file to be included at the beginning of the
+.Pa Makefile Ns s
+generated by
+.Nm .
+This is useful to define some make variables such as
+.Va RELEASE_CRUNCH
+or similar, which might affect the behaviour of
+.Xr make 1
+and are annoying to pass through environment variables.
+.It Fl m Ar makefile-name
+Set output
+.Pa Makefile
+name to
+.Ar makefile-name .
+The default name is
+.Pa <conf-name>.mk .
+.It Fl o
+Add
+.Dq Li make obj
+rules to each program make target.
+.It Fl p Ar obj-prefix
+Set the pathname to be prepended to the
+.Ic srcdir
+when computing the
+.Ic objdir .
+If this option is not present, then the prefix used
+is the content of the
+.Ev MAKEOBJDIRPREFIX
+environment variable, or
+.Pa /usr/obj .
+.It Fl q
+Quiet operation.
+Status messages are suppressed.
+.El
+.Sh CRUNCHGEN CONFIGURATION FILE COMMANDS
+The
+.Nm
+utility reads specifications from the
+.Ar conf-file
+that describe the components of the crunched binary.
+In its simplest
+use, the component program names are merely listed along with the
+top-level source directories in which their sources can be found.
+The
+.Nm
+utility then calculates (via the source makefiles) and caches the
+list of object files and their locations.
+For more specialized
+situations, the user can specify by hand all the parameters that
+.Nm
+needs.
+.Pp
+The
+.Ar conf-file
+commands are as follows:
+.Bl -tag -width indent
+.It Ic srcdirs Ar dirname ...
+A list of source trees in which the source directories of the
+component programs can be found.
+These dirs are searched using the
+.Bx
+.Dq Pa <source-dir>/<progname>/
+convention.
+Multiple
+.Ic srcdirs
+lines can be specified.
+The directories are searched in the order they are given.
+.It Ic progs Ar progname ...
+A list of programs that make up the crunched binary.
+Multiple
+.Ic progs
+lines can be specified.
+.It Ic libs Ar libspec ...
+A list of library specifications to be included in the crunched binary link.
+Multiple
+.Ic libs
+lines can be specified.
+.It Ic buildopts Ar buildopts ...
+A list of build options to be added to every make target.
+.It Ic ln Ar progname linkname
+Causes the crunched binary to invoke
+.Ar progname
+whenever
+.Ar linkname
+appears in
+.Va argv[0] .
+This allows programs that change their behavior when
+run under different names to operate correctly.
+.El
+.Pp
+To handle specialized situations, such as when the source is not
+available or not built via a conventional
+.Pa Makefile ,
+the following
+.Ic special
+commands can be used to set
+.Nm
+parameters for a component program.
+.Bl -tag -width indent
+.It Ic special Ar progname Ic srcdir Ar pathname
+Set the source directory for
+.Ar progname .
+This is normally calculated by searching the specified
+.Ic srcdirs
+for a directory named
+.Ar progname .
+.It Ic special Ar progname Ic objdir Ar pathname
+Set the
+.Pa obj
+directory for
+.Ar progname .
+The
+.Pa obj
+directory is normally calculated by looking for a directory
+whose name is that of the source directory prepended by
+one of the following components, in order of priority:
+the
+.Fl p
+argument passed to the command line; or,
+the value of the
+.Ev MAKEOBJDIRPREFIX
+environment variable, or
+.Pa /usr/obj .
+If the directory is not found, the
+.Ic srcdir
+itself becomes the
+.Ic objdir .
+.It Ic special Ar progname Ic buildopts Ar buildopts
+Define a set of build options that should be added to
+.Xr make 1
+targets in addition to those specified using
+.Ic buildopts
+when processing
+.Ar progname .
+.It Ic special Ar progname Ic objs Ar object-file-name ...
+Set the list of object files for program
+.Ar progname .
+This is normally calculated by constructing a temporary makefile that includes
+.Dq Ic srcdir Ns / Ns Pa Makefile
+and outputs the value of
+.Va $(OBJS) .
+.It Ic special Ar progname Ic objpaths Ar full-pathname-to-object-file ...
+Sets the pathnames of the object files for program
+.Ar progname .
+This is normally calculated by prepending the
+.Ic objdir
+pathname to each file in the
+.Ic objs
+list.
+.It Ic special Ar progname Ic objvar Ar variable_name
+Sets the name of the
+.Xr make 1
+variable which holds the list of
+object files for program
+.Ar progname .
+This is normally
+.Va OBJS
+but some
+.Pa Makefile Ns s
+might like to use other conventions or
+prepend the program's name to the variable, e.g.\&
+.Va SSHD_OBJS .
+.It Ic special Ar progname Ic lib Ar library-name ...
+Specifies libraries to be linked with object files to produce
+.Ar progname Ns Pa .lo .
+This can be useful with libraries which redefine routines in
+the standard libraries, or poorly written libraries which
+reference symbols in the object files.
+.It Ic special Ar progname Ic keep Ar symbol-name ...
+Add specified list of symbols to the keep list for program
+.Ar progname .
+An underscore
+.Pq Ql _
+is prepended to each symbol and it becomes the argument to a
+.Fl k
+option for the
+.Xr crunchide 1
+phase.
+This option is to be used as a last resort as its use can cause a
+symbol conflict, however in certain instances it may be the only way to
+have a symbol resolve.
+.It Ic special Ar progname Ic ident Ar identifier
+Set the
+.Pa Makefile Ns / Ns Tn C
+identifier for
+.Ar progname .
+This is normally generated from a
+.Ar progname ,
+mapping
+.Ql -
+to
+.Ql _
+and ignoring all other non-identifier characters.
+This leads to programs named
+.Qq Li foo.bar
+and
+.Qq Li foobar
+to map to the same identifier.
+.El
+.Pp
+Only the
+.Ic objpaths
+parameter is actually needed by
+.Nm ,
+but it is calculated from
+.Ic objdir
+and
+.Ic objs ,
+which are in turn calculated from
+.Ic srcdir ,
+so is sometimes convenient to specify the earlier parameters and let
+.Nm
+calculate forward from there if it can.
+.Pp
+The makefile produced by
+.Nm
+contains an optional
+.Ic objs
+target that will build the object files for each component program by
+running
+.Xr make 1
+inside that program's source directory.
+For this to work the
+.Ic srcdir
+and
+.Ic objs
+parameters must also be valid.
+If they are not valid for a particular program, that
+program is skipped in the
+.Ic objs
+target.
+.Sh EXAMPLES
+Here is an example
+.Nm
+input conf file, named
+.Dq Pa kcopy.conf :
+.Pp
+.Bd -literal -offset indent
+srcdirs /usr/src/bin /usr/src/sbin
+
+progs test cp echo sh fsck halt init mount umount myinstall
+progs anotherprog
+ln test [       # test can be invoked via [
+ln sh -sh       # init invokes the shell with "-sh" in argv[0]
+
+special myprog objpaths /homes/leroy/src/myinstall.o # no sources
+
+special anotherprog -DNO_FOO WITHOUT_BAR=YES
+
+libs -lutil -lcrypt
+.Ed
+.Pp
+This conf file specifies a small crunched binary consisting of some
+basic system utilities plus a homegrown install program
+.Dq Pa myinstall ,
+for which no source directory is specified, but its object file is
+specified directly with the
+.Ic special
+line.
+.Pp
+Additionally when
+.Dq Pa anotherprog
+is built the arguments
+.Pp
+.Dl -DNO_FOO WITHOUT_BAR=YES
+.Pp
+are added to all build targets.
+.Pp
+The crunched binary
+.Dq Pa kcopy
+can be built as follows:

+.Sh CAVEATS
+While
+.Nm
+takes care to eliminate link conflicts between the component programs
+of a crunched binary, conflicts are still possible between the
+libraries that are linked in.
+Some shuffling in the order of
+libraries may be required, and in some rare cases two libraries may
+have an unresolvable conflict and thus cannot be crunched together.
+.Pp
+Some versions of the
+.Bx
+build environment do not by default build the
+intermediate object file for single-source file programs.
+The
+.Dq Li make objs
+must then be used to get those object files built, or
+some other arrangements made.

+.Sh NAME
+.Nm crunchide
+.Nd hides symbol names from ld, for crunching programs together
+.Sh SYNOPSIS
+.Nm
+.Op Fl f Ar keep-list-file
+.Op Fl k Ar keep-symbol
+.Op Ar object-file ...
+.Sh DESCRIPTION
+The
+.Nm
+utility hides the global symbols of
+.Ar object-file
+such that they are ignored by subsequent runs of the linker,
+.Xr ld 1 .
+Some symbols may be left visible via the
+.Fl k Ar keep-symbol
+and
+.Fl f Ar keep-list-file
+options.  The
+.Ar keep-list-file
+must contain a list of symbols to keep visible, one symbol per line.
+The names given by
+.Ar keep-symbol
+or in
+.Ar keep-list-file
+should be C names.  For example,
+to keep the C function
+.Dq foo
+visible, the option
+.Dq -k foo
+should be used.
+.Pp
+The
+.Nm
+utility is designed as a companion program for
+.Xr crunchgen 1 ,
+which automates the process of creating crunched binaries from
+multiple component programs.
+.Sh SEE ALSO
+.Xr crunchgen 1 ,
+.Xr ld 1
+.Sh AUTHORS
+The
+.Nm crunch
+utility was written by
+.An James da Silva Aq jds@cs.umd.edu .
+.Pp
+Copyright (c) 1994 University of Maryland.  All Rights Reserved.
+.Pp
+Chris Demetriou <cgd@netbsd.org> reorganized
+.Nm
+so that it supported multiple object formats, and added
+ELF object support and ECOFF object recognition.

+/*
+ * crunchide.c - tiptoes through an a.out symbol table, hiding all defined
+ *	global symbols.  Allows the user to supply a "keep list" of symbols
+ *	that are not to be hidden.  This program relies on the use of the
+ * 	linker's -dc flag to actually put global bss data into the file's
+ * 	bss segment (rather than leaving it as undefined "common" data).
+ *
+ * 	The point of all this is to allow multiple programs to be linked
+ *	together without getting multiple-defined errors.
+ *
+ *	For example, consider a program "foo.c".  It can be linked with a
+ *	small stub routine, called "foostub.c", eg:
+ *	    int foo_main(int argc, char **argv){ return main(argc, argv); }
+ *      like so:
+ *	    cc -c foo.c foostub.c
+ *	    ld -dc -r foo.o foostub.o -o foo.combined.o
+ *	    crunchide -k _foo_main foo.combined.o
+ *	at this point, foo.combined.o can be linked with another program
+ * 	and invoked with "foo_main(argc, argv)".  foo's main() and any
+ * 	other globals are hidden and will not conflict with other symbols.
+ *
+ * TODO:
+ *	- resolve the theoretical hanging reloc problem (see check_reloc()
+ *	  below). I have yet to see this problem actually occur in any real
+ *	  program. In what cases will gcc/gas generate code that needs a
+ *	  relative reloc from a global symbol, other than PIC?  The
+ *	  solution is to not hide the symbol from the linker in this case,
+ *	  but to generate some random name for it so that it doesn't link
+ *	  with anything but holds the place for the reloc.
+ *      - arrange that all the BSS segments start at the same address, so
+ *	  that the final crunched binary BSS size is the max of all the
+ *	  component programs' BSS sizes, rather than their sum.

+What will I not find in this file ?
+-----------------------------------
+Instructions on how to obtain FreeBSD via CTM.
+Contact <CTM@FreeBSD.org> for that.
+
+What is CTM ?
+-------------
+CTM was originally "CVS Through eMail", but has since changed scope to be
+much more general.
+CTM is now meant to be the definitive way to make and apply a delta between
+two versions of a directory tree.
+There are two parts to this, making the delta and applying it.  These are two
+entirely different things.  CTM concentrates the computation-burden on the
+generation of the deltas, as a delta very often is applied more times than
+it is made.  Second CTM tries to make the minimal size delta.
+
+Why not use diff/patch ?
+------------------------
+Good question.  Primarily because diff and patch doesn't do their job very 
+well.  They don't deal with binary files (in this case files with '\0' or 
+'\0377' characters in them or files that doesn't end in '\n') which isn't
+a big surprise:  they were made to deal with text-files only.  As a second
+gripe, with patch you send the entire file to delete it.  Not particular
+efficient.
+
+So what does CTM do exactly ?
+-----------------------------
+CTM will produce a file, (a delta) containing the instructions and data needed
+to take another copy of the tree from the old to the new status.  CTM means to
+do this in the exact sense, and therefore the delta contains MD5 checksums to
+verify that the tree it is applied to is indeed in the state CTM expects.
+
+This means that if you have modified the tree locally, CTM might not be able
+to upgrade your copy.
+
+How do I make a CTM-delta ?
+---------------------------
+
+Read the source, and be prepared to have 2 copies of the tree; One is
+the reference ("From") tree, and the other is the delta ("To") tree.
+The mkCTM script will create the CTM diff of the differences between
+the reference tree and the delta tree. A lot of scratch space is
+required, and your machine will work hard.
+
+How do I apply a CTM-delta ?
+----------------------------
+You pass it to the 'ctm' command.  You can pass a CTM-delta on stdin, or
+you can give the filename as an argument.  If you do the latter, you make
+life a lot easier for your self, since the program can accept gzip'ed files
+and since it will not have to make a temporary copy of your file.  You can
+specify multiple deltas at one time, they will be processed one at a time.
+
+The ctm command runs in a number of passes.  It will process the entire
+input file in each pass, before commencing with the next pass.
+
+Pass 1 will validate that the input file is OK.  The syntax, the data and 
+the global MD5 checksum will be checked.  If any of these fail, ctm will
+never be able to do anything with the file, so it will simply reject it.
+
+Pass 2 will validate that the directory tree is in the state expected by
+the CTM-delta.  This is done by looking for files and directories which
+should/should not exists and by checking the MD5 checksums of files.  
+
+Pass 3 will actually apply the delta.
+
+Should I delete the delta when I have applied it ?
+--------------------------------------------------
+No.  You might want to selectively reconstruct a file latter on.
+
+Why is CTM not being maintained?
+--------------------------------
+Because CVSUP has improved on the concept quite a bit, and is now
+the method of choice.

+.Sh DESCRIPTION
+The
+.Nm
+utility was originally
+.Dq Cvs Through eMail ,
+but now instead it seems more fitting to call it
+.Dq Current Through eMail .
+.Pp
+The
+.Nm
+utility is now meant to be the definitive way to make and apply a delta between
+two versions of a directory tree.
+.Pp
+There are two parts to this, making the delta and applying it.  These are two
+entirely different things.
+.Ss Usage
+To apply a CTM delta, you pass it to the
+.Nm
+command.  You can pass a CTM delta on stdin, or you can give the
+filename as an argument.  If you do the latter, you make life a lot
+easier for your self, since the program can accept gzip'ed files and
+since it will not have to make a temporary copy of your file.  You can
+specify multiple deltas at one time, they will be processed one at a
+time.  Deltas that are already applied will be ignored.
+.Pp
+The
+.Nm
+command runs in a number of passes.  It will process the entire
+input file in each pass, before commencing with the next pass.
+.Pp
+Before working on a file
+.Ar name
+.Nm
+first checks for the existence of the file
+.Ar name.ctm .
+If this file exists,
+.Nm
+works on it instead.
+.Pp
+Pass 1 will verify that the input file is OK.  The syntax, the data
+and the global MD5 checksum will be checked.  If any of these fail,
+.Nm
+will simply reject the input file.
+.Pp
+Pass 2 will validate that the directory tree is in the state expected by
+the CTM delta.  This is done by looking for files and directories which
+should/should not exist and by checking the MD5 checksums of files.
+.Pp
+If a
+.Ar backup-file
+had been specified using the
+.Fl B
+option, all files that would be modified by this
+.Nm
+invocation are backed up
+to this file using the archiver command specified by the
+.Fl t
+option.  The default archiver command is
+.Nm "tar -rf %s -T -" .
+.Pp
+Pass 3 will actually apply the delta.
+.Pp
+The list of files that would be modified by
+.Nm
+is subject to filtering regular expressions specified
+using the
+.Fl e
+and
+.Fl x
+options.
+The
+.Fl e
+and
+.Fl x
+options are applied in order of appearance on the command line.  The last
+filter that matched a given file name determines whether the file would be
+operated on or left alone by
+.Nm .
+.Pp
+The
+.Nm
+utility
+will extract the file hierarchy below its working directory.  Absolute
+filenames or filenames containing references through
+.Sq Pa .\&
+and
+.Sq Pa ..\&
+are explicitly prohibited as a security measure.
+.Ss Options
+.Bl -tag -width indent
+.It Fl b Ar basedir
+Prepend the path
+.Ar basedir
+to every filename.
+.It Fl B Ar backup-file
+Backup all files that would be modified by this CTM run to
+.Ar backup-file .
+If any filters are specified using the
+.Fl e
+and
+.Fl x
+options, then the final set of files backed up are those that would be
+modified by CTM after the filters are applied.
+.It Fl c
+Check it out, don't do anything.
+.It Fl e Ar regular_expression
+Match each name in the CTM file against
+.Ar regular_expression ,
+and if it matches process the file, otherwise leave it alone.  There may be
+any number of these options.  Use of this option disables the
+.Pa .ctm_status
+sequence number checks.  For example, the expression
+.Ic ^usr.sbin/ctm
+for example, will select the
+.Pa usr.sbin/ctm
+source directory and all pathnames under it.
+.Pp
+Pathnames can be disabled from being considered by CTM using the
+.Fl x
+option.
+.It Fl F
+Force.
+.It Fl k
+Keep files and directories and don't remove them even if the CTM file
+specifies they are to be removed.  If the
+.Fl B
+option is specified, these files and directories will not be backed up.
+.It Fl l
+List files that would be modified by this invocation of CTM and the
+actions that would be performed on them.  Use of the
+.Fl l
+option disables the
+.Pa .ctm_status
+checks and integrity checks on the source tree being operated on.  The
+.Fl l
+option can be combined with the
+.Fl e
+and
+.Fl x
+options to determine which files would be modified by the given set of
+command line options.
+.It Fl q
+Tell us less.
+.It Fl t Ar tar-command
+Use
+.Ar tar-command
+instead of the default archiver
+.Nm tar .
+This option takes effect only if a backup file had been specified using the
+.Fl B
+option.  A %s in the tar command will be replaced by the name of the backup
+file.
+.It Fl T Ar tmpdir
+Put temporary files under
+.Ar tmpdir .
+.It Fl u
+Set modification time of created and modified files to the CTM delta
+creation time.
+.It Fl v
+Tell us more.
+.It Fl V Ar level
+Tell us more.
+.Ar Level
+is the level of verbosity.
+.It Fl x Ar regular_expression
+Match each name in the CTM file against
+.Ar regular_expression
+and if it matches, leave the file alone.  There may be any number of these
+options.  Use of this option disables the
+.Pa .ctm_status
+sequence number checks.
+.Pp
+Pathnames can be selected for CTM's consideration using the
+.Fl e
+option.
+.El
+.Sh SECURITY
+On its own, CTM is an insecure protocol
+- there is no authentication performed that the
+changes applied to the source code were sent by a
+trusted party, and so care should be taken if the
+CTM deltas are obtained via an unauthenticated
+medium such as regular email.
+It is a relatively simple matter for an attacker
+to forge a CTM delta to replace or precede the
+legitimate one and insert malicious code into your
+source tree.
+If the legitimate delta is somehow prevented from
+arriving, this will go unnoticed until a later
+delta attempts to touch the same file, at which
+point the MD5 checksum will fail.
+.Pp
+To remedy this insecurity, CTM pieces generated by
+FreeBSD.org are cryptographically signed in a
+format compatible with the GNU Privacy Guard
+utility, available in /usr/ports/security/gpg, and
+the Pretty Good Privacy v5 utility,
+/usr/ports/security/pgp5.
+The relevant public key can be obtained by
+fingering ctm@FreeBSD.org.
+.Pp
+CTM deltas which are thus signed cannot be
+undetectably altered by an attacker.
+Therefore it is recommended that you make use of
+GPG or PGP5 to verify the signatures if you
+receive your CTM deltas via email.
+.Sh ENVIRONMENT
+.Ev TMPDIR ,
+if set to a pathname, will cause ctm to use that pathname
+as the location of temporary file.
+See
+.Xr tempnam 3 ,
+for more details on this.
+The same effect may be achieved with the
+.Fl T
+flag.
+.Sh FILES
+.Pa .ctm_status
+contains the sequence number of the last CTM delta applied.  Changing
+or removing this file will greatly confuse
+.Nm .
+.Pp
+Using the
+.Fl e
+and
+.Fl x
+options can update a partial subset of the source tree and causes sources
+to be in an inconsistent state.  It is assumed that you know what you are
+doing when you use these options.
+.Sh EXAMPLES
+.Bd -literal
+cd ~cvs
+/usr/sbin/ctm ~ctm/cvs-*
+.Ed
+.Pp
+To extract and patch all sources under `lib'
+.Bd -literal
+cd ~/lib-srcs
+/usr/sbin/ctm -e '^lib' ~ctm/src-cur*
+.Ed
+.Sh DIAGNOSTICS

+options.

+.Sh NAME
+.Nm ctm
+.Nd source code mirror system
+.Sh DESCRIPTION
+The
+.Nm
+transfers data in a specific file format, called a CTM delta.
+.Pp
+CTM deltas consist of control lines and data chunks.  Each control
+line starts with the letters
+.Dq CTM ,
+followed by a CTM statement and control data, and ends with a '\en'
+character.
+.Pp
+Data chunks always belong to the preceding control line, and the
+last field on that control line is the number of bytes in the data
+chunk.
+A trailing newline '\en' character follows each data chunk, this
+newline is not part of the chunk and isn't included in the count.
+.Pp
+The CTM statements are as follows.
+.Bl -tag -width indent
+.It _BEGIN Ar version name number timestamp prefix
+This is the overall begin of a CTM delta file.  The
+.Ar version
+field must match the program version
+(currently 2.0).
+.Ar Name
+is the name and
+.Ar number
+the sequence number of the CTM service, it is matched against the file
+.Pa .ctm_status
+to see if the delta has already been applied.
+.Ar Timestamp
+contains the year, month, day, hour, minute, and second of the
+time of delta creation for reference
+(followed by the letter
+.Sq Z
+meaning this is a UTC timestamp).
+The
+.Ar prefix
+field is currently not implemented.
+.It _END Ar md5
+This statement ends the CTM delta, the global
+.Ar md5
+checksum is matched against the MD5 checksum of the entire delta, up to
+and including the space (0x20) character following ``_END''.
+.It \&FM Ar name uid gid mode md5 count
+Make the file
+.Ar name ,
+the original file had the uid
+.Ar uid
+(numerical, decimal),
+the gid
+.Ar gid
+(numerical, decimal),
+mode
+.Ar mode
+(numerical, octal),
+and the MD5 checksum
+.Ar md5 .
+.Pp
+The following
+.Ar count
+bytes data are the contents of the new file.
+.It \&FS Ar name uid gid mode md5before md5after count
+Substitute the contents of file
+.Ar name ,
+the original file had the new uid
+.Ar uid
+(numerical, decimal),
+the new gid
+.Ar gid
+(numerical, decimal),
+new mode
+.Ar mode
+(numerical, octal),
+the old MD5 checksum
+.Ar md5before ,
+and the new MD5 checksum
+.Ar md5after .
+.Pp
+The following
+.Ar count
+bytes data are the contents of the new file.
+.Pp
+File substitution is used if the commands to edit a file would exceed
+the total file length, so substituting it is more efficient.
+.It \&FN Ar name uid gid mode md5before md5after count
+Edit the file
+.Ar name .
+The arguments are as above, but the data sections contains an
+.Xr diff 1
+-n script which should be applied to the file in question.
+.It \&FR Ar name md5
+Remove the file
+.Ar name ,
+which must match the MD5 checksum
+.Ar md5 .
+.It \&AS Ar name uid gid mode
+The original file
+.Ar name
+changed its owner to
+.Ar uid ,
+its group to
+.Ar gid ,
+and/or its mode to
+.Ar mode .
+.It \&DM Ar name uid gid mode
+The directory

+.Sh DESCRIPTION
+In conjunction with the
+.Xr ctm 1
+command,
+.Nm ctm_smail ,
+.Nm ctm_dequeue
+and
+.Nm ctm_rmail
+are used to distribute changes to a source tree via email.
+The
+.Nm ctm_smail
+utility is given a compressed
+.Xr ctm
+delta, and a mailing list to send it to.  It splits the delta into manageable
+pieces, encodes them as mail messages and sends them to the mailing list
+(optionally queued to spread the mail load).
+Each recipient uses
+.Nm ctm_rmail
+(either manually or automatically) to decode and reassemble the delta, and
+optionally call
+.Xr ctm
+to apply it to the source tree.
+At the moment,
+several source trees are distributed, and by several sites.  These include
+the
+.Fx Ns -current
+source and CVS trees, distributed by
+.Li freefall.FreeBSD.org .
+.Pp
+Command line arguments for
+.Nm ctm_smail :
+.Bl -tag -width indent
+.It Fl l Ar log
+Instead of appearing on
+.Em stderr ,
+error diagnostics and informational messages (other than command line errors)
+are time stamped and written to the file
+.Em log .
+.It Fl m Ar maxmsgsize
+Limit the maximum size mail message that
+.Nm ctm_smail
+is allowed to send.  It is approximate since mail headers and other niceties
+are not counted in this limit.  If not specified, it will default to 64000
+bytes, leaving room for 1535 bytes of headers before the rumoured 64k mail
+limit.
+.It Fl c Ar maxctmsize
+Limit the maximum size delta that will be sent.  Deltas bigger that this
+limit will cause an apology mail message to be sent to the mailing list.
+This is to prevent massive changes overwhelming users' mail boxes.  Note that
+this is the size before encoding.  Encoding causes a 4/3 size increase before
+mail headers are added.  If not specified, there is no limit.
+.It Fl q Ar queue-dir
+Instead of mailing the delta pieces now, store them in the given directory
+to be mailed later using
+.Nm ctm_dequeue .
+This feature allows the mailing of large deltas to be spread out over
+hours or even days to limit the impact on recipients with limited network
+bandwidth or small mail spool areas.
+.El
+.Pp
+.Ar ctm-delta
+is the delta to be sent, and
+.Ar mail-alias
+is the mailing list to send the delta to.
+The mail messages are sent using
+.Xr sendmail 8 .
+.Pp
+Command line arguments for
+.Nm ctm_dequeue :
+.Bl -tag -width indent
+.It Fl l Ar log
+Instead of appearing on
+.Em stderr ,
+error diagnostics and informational messages (other than command line errors)
+are time stamped and written to the file
+.Em log .
+.It Fl n Ar numchunks
+Limit the number of mail messages that
+.Nm ctm_dequeue
+will send per run.  By default,
+.Nm ctm_dequeue
+will send one mail message per run.
+.El
+.Pp
+.Ar queuedir
+is the directory containing the mail messages stored by
+.Nm ctm_smail .
+Up to
+.Ar numchunks
+mail messages will be sent in each run.  The recipient mailing list is already
+encoded in the queued files.
+.Pp
+It is safe to run
+.Nm ctm_dequeue
+while
+.Nm ctm_smail
+is adding entries to the queue, or even to run
+.Nm ctm_smail
+multiple times concurrently, but a separate queue directory should be used
+for each tree being distributed.  This is because entries are served in
+alphabetical order, and one tree will be unfairly serviced before any others,
+based on the delta names, not delta creation times.
+.Pp
+Command line arguments for
+.Nm ctm_rmail :
+.Bl -tag -width indent
+.It Fl l Ar log
+Instead of appearing on
+.Em stderr ,
+error diagnostics and informational messages (other than command line errors)
+are time stamped and written to the file
+.Em log .
+.It Fl p Ar piecedir
+Collect pieces of deltas in this directory.  Each piece corresponds to a
+single mail message.  Pieces are removed when complete deltas are built.
+If this flag is not given, no input files will be read, but completed
+deltas may still be applied with
+.Xr ctm
+if the
+.Fl b
+flag is given.
+.It Fl d Ar deltadir
+Collect completed deltas in this directory.  Deltas are built from one or
+more pieces when all pieces are present.
+.It Fl b Ar basedir
+Apply any completed deltas to this source tree.  If this flag is not given,
+deltas will be stored, but not applied.  The user may then apply the deltas
+manually, or by using
+.Nm ctm_rmail
+without the
+.Fl p
+flag.
+Deltas will not be applied if they do not match the
+.Li .ctm_status
+file in
+.Ar basedir
+(or if
+.Li .ctm_status
+does not exist).
+.It Fl D
+Delete deltas after successful application by
+.Xr ctm .
+It is probably a good idea to avoid this flag (and keep all the deltas) as
+.Xr ctm
+has the ability to recover small groups of files from a full set of deltas.
+.It Fl f
+Fork and execute in the background while applying deltas with
+.Xr ctm .
+This is useful when automatically invoking
+.Nm ctm_rmail
+from
+.Xr sendmail
+because
+.Xr ctm
+can take a very long time to complete, causing other people's mail to
+be delayed, and can in theory cause spurious
+mail retransmission due to the remote
+.Xr sendmail
+timing out, or even termination of
+.Nm ctm_rmail
+by mail filters such as
+.Xr "MH's"
+.Xr slocal .
+Don't worry about zillions of background
+.Xr ctm
+processes loading your machine, since locking is used to prevent more than one
+.Xr ctm
+invocation at a time.
+.It Fl u
+Pass the
+.Fl u
+flag to the
+.Xr ctm
+command when applying the complete deltas, causing it to set the modification
+time of created and modified files to the CTM delta creation time.
+.It Fl v
+Pass the
+.Fl v
+flag to the
+.Xr ctm
+command when applying the complete deltas, causing a more informative
+output.  All
+.Xr ctm
+output appears in the
+.Nm ctm_rmail
+log file.
+.El
+.Pp
+The file arguments (or
+.Em stdin ,
+if there are none) are scanned for delta pieces.  Multiple delta pieces
+can be read from a single file, so an entire maildrop can be scanned
+and processed with a single command.
+.Pp
+It is safe to invoke
+.Nm ctm_rmail
+multiple times concurrently (with different input files),
+as might happen when
+.Xr sendmail
+is delivering mail asynchronously.  This is because locking is used to
+keep things orderly.
+.Sh FILE FORMAT
+Following are the important parts of an actual (very small) delta piece:
+.Bd -literal
+From: owner-src-cur
+To: src-cur
+Subject: ctm-mail src-cur.0003.gz 1/4
+
+CTM_MAIL BEGIN src-cur.0003.gz 1 4
+H4sIAAAAAAACA3VU72/bNhD9bP0VByQoEiyRSZEUSQP9kKTeYCR2gDTdsGFAwB/HRogtG5K8NCj6
+v4+UZSdtUQh6Rz0eee/xaF/dzx8up3/MFlDkBNrGnbttAwyo1pxoRgoiBNX/QJ5d3c9/X8DcPGGo
+lggkPiXngE4W1gUjKPJCYyk5MZRbIqmNW/ASglIFcdwIzTUxaAqhnCPcBqloKEkJVNDMF0Azk+Bo
+dDzzk0Ods/+A5gXv9YyJHjMCtJwQNeESNma7hOmXDRxn
+CTM_MAIL END 61065
+.Ed
+.Pp
+The subject of the message always begins with
+.Dq ctm-mail
+followed by the name of the delta, which piece this is, and how many total
+pieces there are.  The data are bracketed by
+.Dq CTM_MAIL BEGIN
+and
+.Dq CTM_MAIL END
+lines, duplicating the information in the subject line, plus a simple checksum.
+.Pp
+If the delta exceeds
+.Ar maxctmsize ,
+then a message like this will be received instead:
+.Bd -literal
+From: owner-src-cur
+To: src-cur
+Subject: ctm-notice src-cur.0999.gz
+
+src-cur.0999.gz is 792843 bytes.  The limit is 300000 bytes.
+
+You can retrieve this delta via ftpmail, or your good mate at the university.
+.Ed
+.Pp
+You are then on your own!
+.Sh EXAMPLES
+To send delta 32 of
+.Em src-cur
+to a group of wonderful code hackers known to
+.Xr sendmail
+as
+.Em src-guys ,
+limiting the mail size to roughly 60000 bytes, you could use:
+.Bd -literal -offset indent
+ctm_smail -m 60000 /wherever/it/is/src-cur.0032.gz src-guys
+.Ed
+.Pp
+To decode every
+.Nm ctm-mail
+message in your mailbox, assemble them into complete deltas, then apply
+any deltas built or lying around, you could use:
+.Bd -literal -offset indent
+ctm_rmail -p ~/pieces -d ~/deltas -b /usr/ctm-src-cur $MAIL
+.Ed
+.Pp
+(Note that no messages are deleted by
+.Nm ctm_rmail .
+Any mail reader could be used for that purpose.)
+.Pp
+To create a mail alias called
+.Em receiver-dude
+that will automatically decode and assemble deltas, but not apply them,
+you could put the following lines in your
+.Pa /etc/mail/aliases
+file (assuming the
+.Pa /ctm/tmp
+and
+.Pa /ctm/deltas
+directories and
+.Pa /ctm/log
+file are writable by user
+.Em daemon
+or group
+.Em wheel ) :
+.Bd -literal -offset indent
+receiver-dude: "|ctm_rmail -p /ctm/tmp -d /ctm/deltas -l /ctm/log"
+owner-receiver-dude: real_dude@wherever.you.like
+.Ed
+.Pp
+The second line will catch failures and drop them into your regular mailbox,
+or wherever else you like.
+.Pp
+To apply all the deltas collected, and delete those applied, you could use:
+.Bd -literal -offset indent
+ctm_rmail -D -d /ctm/deltas -b /ctm/src-cur -l /ctm/apply.log
+.Ed
+.Pp
+For maximum flexibility, consider this excerpt from a
+.Xr procmail
+script:
+.Bd -literal -offset indent
+PATH=$HOME/bin:$PATH
+
+:0 w
+* ^Subject: ctm-mail cvs-cur
+| ctm_incoming
+.Ed
+.Pp
+together with the
+shell script
+.Pa ~/bin/ctm_incoming :
+.Bd -literal -offset indent
+#! /bin/sh
+PATH="$HOME/bin:/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin"
+export PATH
+
+cd $HOME/ctm && ctm_rmail -f -p pieces -d deltas -l log -b /ctm
+.Ed
+.Pp
+which will deposit all
+.Xr ctm
+deltas in
+.Pa ~/ctm/deltas ,
+apply them to the tree in
+.Pa /ctm ,
+and drop any failures into your regular mail box.
+Note the
+.Ev PATH
+manipulation in
+.Pa ctm_incoming
+which allows
+.Nm ctm_rmail
+to execute
+.Xr ctm 1
+on the
+.Pq non- Ns Fx
+machine that this example was taken from.
+.Sh SECURITY
+On its own, CTM is an insecure protocol
+- there is no authentication performed that the
+changes applied to the source code were sent by a
+trusted party, and so care should be taken if the
+CTM deltas are obtained via an unauthenticated
+medium such as regular email.
+It is a relatively simple matter for an attacker
+to forge a CTM delta to replace or precede the
+legitimate one and insert malicious code into your
+source tree.
+If the legitimate delta is somehow prevented from
+arriving, this will go unnoticed until a later
+delta attempts to touch the same file, at which
+point the MD5 checksum will fail.
+.Pp
+To remedy this insecurity, CTM delta pieces generated by
+FreeBSD.org are cryptographically signed in a
+format compatible with the GNU Privacy Guard
+utility, available in /usr/ports/security/gpg, and
+the Pretty Good Privacy v5 utility,
+/usr/ports/security/pgp5.
+The relevant public key can be obtained by
+fingering ctm@FreeBSD.org.
+.Pp
+CTM deltas which are thus signed cannot be
+undetectably altered by an attacker.
+Therefore it is recommended that you make use of
+GPG or PGP5 to verify the signatures if you
+receive your CTM deltas via email.
+.\" This next request is for sections 1, 6, 7 & 8 only
+.Sh ENVIRONMENT
+If deltas are to be applied then
+.Xr ctm 1
+and
+.Xr gunzip 1
+must be in your
+.Ev PATH .
+.Sh FILES
+.Bl -tag -width indent
+.It Pa QUEUEDIR/*
+Pieces of deltas encoded as mail messages waiting to be sent to the
+mailing list.
+.It Pa PIECEDIR/*
+Pieces of deltas waiting for the rest to arrive.
+.It Pa DELTADIR/*
+Completed deltas.
+.It Pa BASEDIR/.ctm_status
+File containing the name and number of the next delta to be applied to this
+source tree.
+.El
+.Sh DIAGNOSTICS
+The
+.Nm ctm_smail ,
+.Nm ctm_dequeue
+and
+.Nm ctm_rmail
+utilities return exit status 0 for success, and 1 for various failures.
+The
+.Nm ctm_rmail
+utility is expected to be called from a mail transfer program, and thus signals
+failure only when the input mail message should be bounced (preferably into
+your regular maildrop, not back to the sender).  In short, failure to
+apply a completed delta with
+.Xr ctm
+is not considered an error important enough to bounce the mail, and
+.Nm ctm_rmail
+returns an exit status of 0.
+.Pp
+In normal operation,
+.Nm ctm_smail
+will report messages like:
+.Bd -literal -offset indent
+ctm_smail: src-cur.0250.gz 1/2 sent to src-guys
+.Ed
+.Pp
+or, if queueing,
+.Bd -literal -offset indent
+ctm_smail: src-cur.0250.gz 1/2 queued for src-guys
+.Ed
+.Pp
+The
+.Nm ctm_dequeue
+utility will report messages like:
+.Bd -literal -offset indent
+ctm_dequeue: src-cur.0250.gz 1/2 sent
+.Ed
+.Pp
+The
+.Nm ctm_rmail
+utility will report messages like:
+.Bd -literal -offset indent
+ctm_rmail: src-cur.0250.gz 1/2 stored
+ctm_rmail: src-cur.0250.gz 2/2 stored
+ctm_rmail: src-cur.0250.gz complete
+.Ed
+.Pp
+If any of the input files do not contain a valid delta piece,
+.Nm ctm_rmail
+will report:
+.Bd -literal -offset indent
+ctm_rmail: message contains no delta
+.Ed
+.Pp
+and return an exit status of 1.  You can use this to redirect wayward messages
+back into your real mailbox if your mail filter goes wonky.
+.Pp
+These messages go to
+.Em stderr
+or to the log file.  Messages from
+.Xr ctm 1
+turn up here too.  Error messages should be self explanatory.

+in the system, starting from the
+.Dq nexus
+device.
+.Pp
+The following options are accepted.
+.Bl -tag -width indent
+.It Fl r
+Causes hardware resource information (such as IRQ, I/O ports, I/O memory
+addresses) to be also listed, under each device that has reserved those resources.
+.It Fl u
+Displays the same information as with
+.Fl r
+but sorts by resource type rather than by device, allowing to review the
+set of system resources by usage and available resources.
+I.e., it lists all
+the IRQ consumers together.

+.Sh DESCRIPTION
+The
+.Nm
+program provides control of the
+.Tn Digiboard
+installed with the given
+.Ar ctrl-device
+name and provides control of individual digiboard
+.Ar devices .
+A digiboard
+.Ar ctrl-device
+is usually of the form
+.Sm off
+.Pa /dev/digi Ar N Pa .ctl
+.Sm on
+where
+.Ar N
+is the card number and starts at
+.Dq 0
+for the first attached card.
+A digiboard
+.Ar device
+is usually of the form
+.Sm off
+.Pa /dev/cua Oo Pa il Oc Pa D Ar N Pa \&. Ar P
+.Sm on
+or
+.Sm off
+.Pa /dev/tty Oo Pa il Oc Pa D Ar N Pa \&. Ar P
+.Sm on
+where
+.Ar N
+is the card number and
+.Ar P
+is the port number.
+.Pp
+The following flags are recognized:
+.Bl -tag
+.It Fl a Cm disable | enable | query
+Disable, enable or query the
+.Em ALTPIN
+settings for the given port(s).
+.Pp
+When ALTPIN is enabled, the CD and DSR lines are logically reversed.
+This is useful when wiring serial ports to an 8 way RJ45 cable (full
+10 way RJ45 cables are quite rare).
+.Pp
+A single ALTPIN setting applies to both of the callout and callin devices.
+.It Fl d Ar debug
+If the driver has been compiled with
+.Dv DEBUG
+defined, the following bits from the
+.Ar debug
+variable are used to enable diagnostics in the digiboard driver:
+.Bl -tag -width ".No 1024 ( Em MODEM )"
+.It 1 ( Em INIT )
+Diagnostics during card attach, detach and initialization.
+.It 2 ( Em OPEN )
+Diagnostics when opening a port.
+.It 4 ( Em CLOSE )
+Diagnostics when closing a port.
+.It 8 ( Em SET )
+Diagnostics when setting tty device flags.
+.It 16 ( Em INT )
+Diagnostics when processing card events.
+.It 32 ( Em READ )
+Reports return values from port reads.
+.It 64 ( Em WRITE )
+Reports return values from port writes.
+.It 128 ( Em RX )
+Reports receive queue flow control.
+.It 256 ( Em TX )
+Reports transmit queue flow control.
+.It 512 ( Em IRQ )
+Diagnostics during interrupts (enable these with care).
+.It 1024 ( Em MODEM )
+Diagnostics when setting modem status flags.
+.It 2048 ( Em RI )
+Reports when a RING is received.
+.El
+.It Fl i
+Display the card identification string and type ID.
+.It Fl r
+Reinitialize the card.
+For boards with external port modules, it is possible to add or remove
+modules and dynamically reprobe the number of ports using this switch.
+All ports on the card must be closed in order to reinitialize the card.
+.Pp
+It is preferable to reinitialize the card rather than reload the entire
+digi module as reinitialization only affects the specified board rather
+than affecting all attached boards.
+.El
+.Sh BUGS
+It should be possible to reinitialize a board without closing all of the
+existing ports.
+.Sh HISTORY
+The
+.Nm
+command first appeared in
+.Fx 5.0 .

+.Nd edit user quotas
+.Sh SYNOPSIS
+.Nm
+.Op Fl u
+.Op Fl f Ar fspath
+.Op Fl p Ar proto-username
+.Ar username ...
+.Nm
+.Fl g
+.Op Fl f Ar fspath
+.Op Fl p Ar proto-groupname
+.Ar groupname ...
+.Nm
+.Fl t
+.Op Fl u
+.Op Fl f Ar fspath
+.Nm
+.Fl t
+.Fl g
+.Op Fl f Ar fspath
+.Sh DESCRIPTION
+.Nm Edquota
+is a quota editor.
+By default, or if the
+.Fl u
+flag is specified,
+one or more users may be specified on the command line.
+For each user a temporary file is created
+with an
+.Tn ASCII
+representation of the current
+disk quotas for that user.
+The list of filesystems with user quotas is determined from
+.Pa /etc/fstab .
+An editor is invoked on the
+.Tn ASCII
+file.
+The editor invoked is
+.Xr vi 1
+unless the environment variable
+.Ev EDITOR
+specifies otherwise.
+.Pp
+The quotas may then be modified, new quotas added, etc.
+Setting a quota to zero indicates that no quota should be imposed.
+Setting a hard limit to one indicates that no allocations should
+be permitted.
+Setting a soft limit to one with a hard limit of zero
+indicates that allocations should be permitted only on
+a temporary basis (see
+.Fl t
+below).
+The current usage information in the file is for informational purposes;
+only the hard and soft limits can be changed.
+.Pp
+On leaving the editor,
+.Nm
+reads the temporary file and modifies the binary
+quota files to reflect the changes made.
+.Pp
+If the
+.Fl p
+option is specified,
+.Nm
+will duplicate the quotas of the prototypical user
+specified for each user specified.
+This is the normal mechanism used to
+initialize quotas for groups of users.
+If the user given to assign quotas to is a numerical uid
+range (e.g. 1000-2000), then
+.Nm
+will duplicate the quotas of the prototypical user
+for each uid in the range specified.  This allows
+for easy setup of default quotas for a group of users.
+The uids in question do not have to be currently assigned in
+.Pa /etc/passwd .
+.Pp
+If invoked with the
+.Fl f
+option,
+.Nm
+will read and modify quotas on the filesystem specified by
+.Ar fspath
+only.
+The
+.Ar fspath
+argument may be either a special device
+or a filesystem mount point.
+The primary purpose of this option is to set the scope for the
+.Fl p
+option, which would overwrite quota records on every
+filesystem with quotas otherwise.
+.Pp
+If the
+.Fl g
+flag is specified,
+.Nm
+is invoked to edit the quotas of
+one or more groups specified on the command line.
+The
+.Fl p
+flag can be specified in conjunction with
+the
+.Fl g
+flag to specify a prototypical group
+to be duplicated among the listed set of groups.
+.Pp
+Users are permitted to exceed their soft limits
+for a grace period that may be specified per filesystem.
+Once the grace period has expired,
+the soft limit is enforced as a hard limit.
+The default grace period for a filesystem is specified in
+.Pa /usr/include/ufs/ufs/quota.h .
+The
+.Fl t
+flag can be used to change the grace period.
+By default, or when invoked with the
+.Fl u
+flag,
+the grace period is set for all the filesystems with user
+quotas specified in
+.Pa /etc/fstab .
+When invoked with the
+.Fl g
+flag the grace period is
+set for all the filesystems with group quotas specified in
+.Pa /etc/fstab .
+The grace period may be specified in days, hours, minutes, or seconds.
+Setting a grace period to zero indicates that the default
+grace period should be imposed.
+Setting a grace period to one second indicates that no
+grace period should be granted.
+.Pp
+Only the super-user may edit quotas.
+.Sh FILES
+.Bl -tag -width quota.group -compact
+.It Pa quota.user
+at the filesystem root with user quotas

+.Dt ELF2EXE 8 Alpha
+.Os
+.Sh NAME
+.Nm elf2exe
+.Nd convert Alpha ELF executable to AlphaBIOS / ARCS format
+.Sh SYNOPSIS
+.Nm
+.Ar infile
+.Ar outfile
+.Sh DESCRIPTION
+.Nm Elf2exe
+creates an executable that can be loaded by the AlphaBIOS or ARCS consoles
+as found on systems designed for
+.Tn Windows/NT .
+The input file must have been
+created as a non-relocatable standalone binary with a load address within
+the memory range available for user programs (0x80000000 to 0x806fdfff
+and 0x80900000 to at least 0x80ffffff).
+.Pp
+The command prints a list of sections found in the ELF executable and the
+section sizes and offsets of the output file for diagnostic purposes.
+.Pp
+Given an object file
+.Pa src.o
+the following two commands will create a binary for ARCS:
+.Bd -literal -offset indent
+ld -o a.out -M -N -Ttext 0x80900000 src.o
+elf2exe a.out a.exe
+.Ed
+.Sh BUGS
+.Nm Elf2exe
+does not even attempt to verify that the input file matches the requirements
+for an ARC executable.
+.Sh HISTORY
+The
+.Nm
+command appeared in
+.Fx 4.0 .

+.Sh NAME
+.Nm extattrctl
+.Nd manage UFS1 extended attributes
+.Sh SYNOPSIS
+.Nm
+.Cm start
+.Ar path
+.Nm
+.Cm stop
+.Ar path
+.Nm
+.Cm initattr
+.Op Fl f
+.Op Fl p Ar path
+.Ar attrsize
+.Ar attrfile
+.Nm
+.Cm showattr
+.Ar attrfile
+.Nm
+.Cm enable
+.Ar path
+.Ar attrnamespace
+.Ar attrname
+.Ar attrfile
+.Nm
+.Cm disable
+.Ar path
+.Ar attrnamespace
+.Ar attrname
+.Sh DESCRIPTION
+.Nm
+is the management utility for extended attributes over the UFS1 file system.
+.Nm
+allows the starting and stopping of extended attributes on a file system,
+as well as initialization of attribute backing files, and enabling and
+disabling of specific extended attributes on a file system.
+.Pp
+The first argument on the command line indicates the operation to be
+performed.
+Operation must be one of the following:
+.Bl -tag -width indent
+.It Cm start Ar path
+Start extended attribute support on the file system named using
+.Ar path .
+The file system must be an UFS1 file system, and the UFS_EXTATTR kernel
+option must have been enabled.
+.It Cm stop Ar path
+Stop extended attribute support on the file system named using
+.Ar path .
+Extended attribute support must previously have been started.
+.It Xo
+.Cm initattr
+.Op Fl f
+.Op Fl p Ar path
+.Ar attrsize attrfile
+.Xc
+Create and initialize a file to use as an attribute backing file.
+You must specify a maximum per-inode size for the attribute in bytes in
+.Ar attrsize ,
+as well as the file where the attribute will be stored, using
+.Ar attrfile .
+.Pp
+The
+.Fl f
+argument may be used to indicate that it is alright to overwrite an
+existing attribute backing file; otherwise, if the target file exists,
+an error will be returned.
+.Pp
+The
+.Fl p Ar path
+argument may be used to preallocate space for all attributes rather than
+relying on sparse files to conserve space.
+This has the advantage of guaranteeing that space will be available
+for attributes when they are written, preventing low disk space conditions
+from denying attribute service.
+.Pp
+This file should not exist before running
+.Cm initattr .
+.It Cm showattr Ar attrfile
+Show the attribute header values in the attribute file named by
+.Ar attrfile .
+.It Cm enable Ar path attrnamespace attrname attrfile
+Enable an attribute named
+.Ar attrname
+in the namespace
+.Ar attrnamespace
+on the file system identified using
+.Ar path ,
+and backed by initialized attribute file
+.Ar attrfile .
+Available namespaces are "user" and "system".
+The backing file must have been initialized using
+.Cm initattr
+before its first use.
+Attributes must have been started on the file system prior to the
+enabling of any attributes.
+.It Cm disable Ar path attrnamespace attrname
+Disable the attributed named
+.Ar attrname
+in namespace
+.Ar attrnamespace
+on the file system identified by
+.Ar path .
+Available namespaces are "user" and "system".
+The file system must have attributes started on it, and the attribute
+most have been enabled using
+.Cm enable .
+.El
+.Sh EXAMPLES
+.Dl extattrctl start /
+.Pp
+Start extended attributes on the root file system.
+.Pp
+.Dl extattrctl initattr 17 /.attribute/md5
+.Pp
+Create an attribute backing file in /.attribute/md5, and set the maximum
+size of each attribute to 17 bytes, with a sparse file used for storing
+the attributes.
+.Pp
+.Dl extattrctl enable / system md5 /.attribute/md5
+.Pp
+Enable an attribute named md5 on the root file system, backed from the file
+/.attribute/md5.
+.Pp
+.Dl extattrctl disable / md5
+.Pp
+Disable the attribute named md5 on the root file system.
+.Pp
+.Dl extattrctl stop /
+.Pp
+Stop extended attributes on the root file system.

+.Sh HISTORY
+Extended attribute support was developed as part of the TrustedBSD Project,
+and introduced in
+.Fx 5.0 .
+It was developed to support security extensions requiring additional labels
+to be associated with each file or directory.

+Configuring FAITH IPv6-to-IPv4 TCP relay
+
+Kazu Yamamoto and Jun-ichiro itojun Hagino

+
+Introduction
+============
+
+FAITH is a IPv6-to-IPv4 TCP relay.  It performs tcp relay just as some of
+firewall-oriented gateway does, but between IPv6 and IPv4 with address
+translation.
+TCP connections has to be made from IPv6 node to IPv4 node.  FAITH will
+not relay connections for the opposite direction.
+To perform relays, FAITH daemon needs to be executed on a router between
+your local IPv6 site and outside IPv4 network.  The daemon needs to be
+invoked per each TCP services (TCP port number).
+
+	IPv4 node "dest" = 123.4.5.6
+		|
+	[[[[ outside IPv4 ocean ]]]]
+		|
+	node that runs FAITH-daemon (usually a router)
+		|
+	==+=====+===+==== IPv6, or IPv4/v6 network in your site ^
+	  |	    |						| connection
+	clients	  IPv6 node "src"				|
+
+You will have to allocate an IPv6 address prefix to map IPv4 addresses into.
+The following description uses 3ffe:0501:ffff:0000:: as example.
+Please use a prefix which belongs to your site.
+FAITH will make it possible to make a IPv6 TCP connection From IPv6 node
+"src", toward IPv4 node "dest", by specifying FAITH-mapped address
+3ffe:0501:ffff:0000::123.4.5.6
+(which is, 3ffe:0501:ffff:0000:0000:0000:7b04:0506).
+The address mapping can be performed by hand:-), by special nameserver on
+the network, or by special resolver on the source node.
+
+
+Setup
+=====
+
+The following example assumes:
+- You have assigned 3ffe:0501:ffff:0000:: as FAITH adderss prefix.
+- You are willing to provide IPv6-to IPv4 TCP relay for telnet.
+
+<<On the translating router on which faithd runs>>
+
+(1) If you have IPv6 TCP server for the "telnet" service, i.e. telnetd via
+    inet6d, disable that daemon.  Comment out the line from "inet6d.conf"
+    and send the HUP signal to "inet6d".
+
+(2) Execute sysctl as root to enable FAITH support in the kernel.
+
+        # sysctl net.inet6.ip6.keepfaith=1
+
+(3) Route packets toward FAITH prefix into "faith0" interface.
+
+	# ifconfig faith0 up
+	# route add -inet6 3ffe:0501:ffff:0000:: -prefixlen 64 ::1
+	# route change -inet6 3ffe:0501:ffff:0000:: -prefixlen 64 -ifp faith0
+
+(4) Execute "faithd" by root as follows:
+
+	# faithd telnet /usr/libexec/telnetd telnetd
+
+    1st argument is a service name you are willing to provide TCP relay.
+	(it can be specified either by number "23" or by string "telnet")
+    2nd argument is a path name for local IPv6 TCP server.  If there is a
+    connection toward the router itself, this program will be invoked.
+    3rd and the following arguments are arguments for the local IPv6 TCP
+    server.  (3rd argument is typically the program name without its path.)
+
+    More examples:
+
+	# faithd login /usr/libexec/rlogin rlogind
+	# faithd shell /usr/libexec/rshd rshd
+	# faithd ftpd /usr/libexec/ftpd ftpd -l
+	# faithd sshd
+
+If inetd(8) on your platform have special support for faithd, it is possible
+to setup faithd services via inetd(8).  Consult manpage for details.
+
+
+<<Routing>>
+
+(4) Make sure that packets whose destinations match the prefix can
+reach from the IPv6 host to the translating router.
+
+<<On the IPv6 host>>
+
+There are two ways to translate IPv4 address to IPv6 address:
+	(a) Faked by DNS
+	(b) Faked by /etc/hosts.
+
+(5.a) Install "newbie" and set up FAITH mode. See kit/ports/newbie.
+
+(5.b) Add an entry into /etc/hosts so that you can resolve hostname into
+faked IPv6 addrss.  For example, add the following line for www.netbsd.org:
+
+	3ffe:0501:ffff:0000::140.160.140.252	www.netbsd.org
+
+<<On the translating router on which faithd runs.>>
+
+(6) To see if "faithd" works, watch "/var/log/daemon". Note: please
+setup "/etc/syslog.conf" so that LOG_DAEMON messages are to be stored
+in "/var/log/daemon".
+
+	<e.g.>
+	daemon.*   /var/log/daemon
+
+
+Access control
+==============
+
+Since faithd implements TCP relaying service, it is critical to implement
+proper access control to cope with malicious use.  Bad guy may try to
+use your relay router to circumvent access controls, or may try to
+abuse your network (like sending SPAMs from IPv4 address that belong to you).
+Install IPv6 packet filter directives that would reject traffic from
+unwanted source.  If you are using inetd-based setup, you may be able to
+use access control mechanisms in inetd.
+
+
+Advanced configuration
+======================
+
+If you would like to restrict IPv4 destination for translation, you may
+want to do the following:
+
+	# route add -inet6 3ffe:0501:ffff:0000::123.0.0.0 -prefixlen 104 ::1
+	# route change -inet6 3ffe:0501:ffff:0000::123.0.0.0 -prefixlen 104 \
+		-ifp faith0
+
+By this way, you can restrict IPv4 destination to 123.0.0.0/8.
+You may also want to reject packets toward 3ffe:0501:ffff:0000::/64 which
+is not in 3ffe:0501:ffff:0000::123.0.0.0/104.  This will be left as excerside
+for the reader.
+
+By doing this, you will be able to provide your IPv4 web server to outside
+IPv6 customers, without risks of unwanted open relays.

+.Nd FAITH IPv6/v4 translator daemon
+.Sh SYNOPSIS
+.Nm
+.Op Fl dp
+.Op Fl f Ar configfile
+.Ar service
+.Op Ar serverpath Op Ar serverargs
+.Sh DESCRIPTION
+.Nm
+provides IPv6-to-IPv4 TCP relay.
+.Nm
+must be used on an IPv4/v6 dual stack router.
+.Pp
+When
+.Nm
+receives
+.Tn TCPv6
+traffic,
+.Nm
+will relay the
+.Tn TCPv6
+traffic to
+.Tn TCPv4 .
+Destination for relayed
+.Tn TCPv4
+connection will be determined by the last 4 octets of the original
+.Tn IPv6
+destination.
+For example, if
+.Li 3ffe:0501:4819:ffff::
+is reserved for
+.Nm ,
+and the
+.Tn TCPv6
+destination address is
+.Li 3ffe:0501:4819:ffff::0a01:0101 ,
+the traffic will be relayed to IPv4 destination
+.Li 10.1.1.1 .
+.Pp
+To use
+.Nm
+translation service,
+an IPv6 address prefix must be reserved for mapping IPv4 addresses into.
+Kernel must be properly configured to route all the TCP connection
+toward the reserved IPv6 address prefix into the
+.Xr faith 4
+pseudo interface, by using
+.Xr route 8
+command.
+Also,
+.Xr sysctl 8
+should be used to configure
+.Dv net.inet6.ip6.keepfaith
+to
+.Dv 1 .
+.Pp
+The router must be configured to capture all the TCP traffic
+toward reserved
+.Tn IPv6
+address prefix, by using
+.Xr route 8
+and
+.Xr sysctl 8
+commands.
+.Pp
+.Nm
+needs a special name-to-address translation logic, so that
+hostnames gets resolved into special
+.Tn IPv6
+address prefix.
+For small-scale installation, use
+.Xr hosts 5 .
+For large-scale installation, it is useful to have
+a DNS server with special address translation support.
+An implementation called
+.Nm totd
+is available
+at
+.Pa http://www.vermicelli.pasta.cs.uit.no/ipv6/software.html .
+Make sure you do not propagate translated DNS records to normal DNS cloud,
+it is highly harmful.
+.Pp
+.Ss Daemon mode
+When
+.Nm
+is invoked as a standalone program,
+.Nm
+will daemonize itself.
+.Nm
+will listen to
+.Tn TCPv6
+port
+.Ar service .
+If
+.Tn TCPv6
+traffic to port
+.Ar service
+is found, it relays the connection.
+.Pp
+Since
+.Nm
+listens to TCP port
+.Ar service ,
+it is not possible to run local TCP daemons for port
+.Ar service
+on the router, using
+.Xr inetd 8
+or other standard mechanisms.
+By specifying
+.Ar serverpath
+to
+.Nm ,
+you can run local daemons on the router.
+.Nm
+will invoke local daemon at
+.Ar serverpath
+if the destination address is local interface address,
+and will perform translation to IPv4 TCP in other cases.
+You can also specify
+.Ar serverargs
+for the arguments for the local daemon.
+.Pp
+The following options are available:
+.Bl -tag -width indent
+.It Fl d
+Debugging information will be generated using
+.Xr syslog 3 .
+.It Fl f Ar configfile
+Specify a configuration file for access control.
+See below.
+.It Fl p
+Use privileged TCP port number as source port,
+for IPv4 TCP connection toward final destination.
+For relaying
+.Xr ftp 1
+and
+.Xr rlogin 1 ,
+this flag is not necessary as special program code is supplied.
+.El
+.Pp
+.Nm
+will relay both normal and out-of-band TCP data.
+It is capable of emulating TCP half close as well.
+.Nm
+includes special support for protocols used by
+.Xr ftp 1
+and
+.Xr rlogin 1 .
+When translating FTP protocol,
+.Nm
+translates network level addresses in
+.Li PORT/LPRT/EPRT
+and
+.Li PASV/LPSV/EPSV
+commands.
+For RLOGIN protocol,
+.Nm
+will relay back connection from
+.Xr rlogind 8
+on the server to
+.Xr rlogin 1
+on client.
+.Pp
+Inactive sessions will be disconnected in 30 minutes,
+to avoid stale sessions from chewing up resources.
+This may be inappropriate for some of the services
+(should this be configurable?).
+.Ss inetd mode
+When
+.Nm
+is invoked via
+.Xr inetd 8 ,
+.Nm
+will handle connection passed from standard input.
+If the connection endpoint is in the reserved IPv6 address prefix,
+.Nm
+will relay the connection.
+Otherwise,
+.Nm
+will invoke service-specific daemon like
+.Xr telnetd 8 ,
+by using the command argument passed from
+.Xr inetd 8 .
+.Pp
+.Nm
+determines operation mode by the local TCP port number,
+and enables special protocol handling whenever necessary/possible.
+For example, if
+.Nm
+is invoked via
+.Xr inetd 8
+on FTP port, it will operate as a FTP relay.
+.Pp
+The operation mode requires special support for
+.Nm
+in
+.Xr inetd 8 .
+.Ss Access control
+To prevent malicious accesses,
+.Nm
+implements a simple address-based access control.
+With
+.Pa /etc/faithd.conf
+(or
+.Ar configfile
+specified by
+.Fl f ) ,
+.Nm
+will avoid relaying unwanted traffic.
+The
+.Pa faithd.conf
+contains directives with the following format:
+.Bl -bullet
+.It
+.Ar src Ns / Ns Ar slen Cm deny Ar dst Ns / Ns Ar dlen
+.Pp
+If the source address of a query matches
+.Ar src Ns / Ns Ar slen ,
+and the translated destination address matches
+.Ar dst Ns / Ns Ar dlen ,
+deny the connection.
+.It
+.Ar src Ns / Ns Ar slen Cm permit Ar dst Ns / Ns Ar dlen
+.Pp
+If the source address of a query matches
+.Ar src Ns / Ns Ar slen ,
+and the translated destination address matches
+.Ar dst Ns / Ns Ar dlen ,
+permit the connection.
+.El
+.Pp
+The directives are evaluated in sequence,
+and the first matching entry will be effective.
+If there is no match
+(if we reach the end of the ruleset)
+the traffic will be denied.
+.Pp
+With inetd mode,
+traffic may be filtered by using access control functionality in
+.Xr inetd 8 .
+.Sh EXAMPLES
+Before invoking
+.Nm ,
+.Xr faith 4
+interface has to be configured properly.

+.Sh HISTORY
+The
+.Nm
+command first appeared in WIDE Hydrangea IPv6 protocol stack kit.
+.\"
+.Pp
+IPv6 and IPsec support based on the KAME Project (http://www.kame.net/) stack
+was initially integrated into
+.Fx 4.0
+.Sh SECURITY CONSIDERATIONS
+It is very insecure to use
+.Xr rhosts 5
+and other IP-address based authentication, for connections relayed by
+.Nm
+(and any other TCP relaying services).
+.Pp
+Administrators are advised to limit accesses to
+.Nm
+using
+.Pa faithd.conf ,
+or by using IPv6 packet filters.
+It is to protect
+.Nm
+service from malicious parties and avoid theft of service/bandwidth.
+IPv6 destination address can be limited by
+carefully configuring routing entries that points to
+.Xr faith 4 ,
+using
+.Xr route 8 .
+IPv6 source address needs to be filtered by using packet filters.
+Documents listed in
+.Sx SEE ALSO

+.Sh NAME
+.Nm fdcontrol
+.Nd display and modify floppy disk parameters
+.Sh SYNOPSIS
+.Nm
+.Op Fl F
+.Op Fl d Ar dbg
+.Op Fl f Ar fmt
+.Op Fl s Ar fmtstr
+.Op Fl v
+.Ar device
+.Sh DESCRIPTION
+The
+.Nm
+utility allows the modification of the run-time behavior of the
+.Xr fdc 4
+driver for the device specified by
+.Ar device .
+.Pp
+Commands are implemented to query the current device density settings
+as well as the underlying device hardware as registered with the
+driver, to manipulate debugging levels, and to adjust the device
+density settings.
+All the operations that manipulate the kernel
+settings are restricted to the superuser (by the device driver), while
+all inquiry requests only require read access to
+.Ar device .
+.Pp
+The
+.Ar device
+argument should always be given as a full path name, e.g.\&
+.Pa /dev/fd0 .
+.Ss Inquiry Commands
+Running the
+.Nm
+utility without any of the optional flags will report the drive type
+that has been registered with the device driver.
+In the shortest form, a single string describing the drive type will
+be returned.
+Possible values are:
+.Dq Li 360K ,
+.Dq Li 1.2M ,
+.Dq Li 720K ,
+.Dq Li 1.44M ,
+.Dq Li 2.88M ,
+or
+.Dq Li unknown .
+This information is primarily intented to be easily parsable by
+scripts.
+.Pp
+In order to add some descriptive text that makes the output better
+human readable, the flag
+.Fl v
+can be added.
+.Pp
+Specifying flag
+.Fl F
+will report the device's density settings in a form that is suitable
+as input to the
+.Fl s Ar fmtstr
+option (see below).
+Again, together with
+.Fl v ,
+some more text will be returned, including the total capacity of the
+density settings in kilobytes.
+.Ss Debug Control
+If the
+.Xr fdc 4
+driver has been configured with the
+.Dv FDC_DEBUG
+option, by default, device debugging information is still disabled
+since it could produce huge amounts of kernel messages.
+It needs to
+be turned on using
+.Nm
+together with
+.Dq Fl d Li 1 ,
+usually immediately before starting an operation on the respective
+device the debug information is wanted for, and later turned off again
+using
+.Dq Fl d Li 0 .
+Note that debugging levels are a driver's global option that will
+affect any drives and controllers using the
+.Xr fdc 4
+driver, regardless which
+.Ar device
+has been specified on the
+.Nm
+command line.
+.Ss Density Control
+The
+.Xr fdc 4
+control utilities support two different options how to specify device
+density settings.
+The first form uses
+.Fl f Ar fmt
+to specify the format of the medium in kilobytes.
+Depending on the

+.Pp
+The second form to specify a device density uses
+.Fl s Ar fmtstr
+to explicitly specify each parameter in detail.
+The argument
+.Ar fmtstr
+is a comma-separated list of values of the form:
+.Pp
+.Sm off
+.Ar sectrac , secsize , datalen , gap , ncyls , speed ,
+.Ar heads , f_gap , f_inter , offs2 , flags
+.Sm on
+.Pp
+The meaning of the parameters is:
+.Bl -tag -width ".Ar secsize"
+.It Ar sectrac
+The number of sectors per track.
+.It Ar secsize
+The sector size code, 0 = 128 bytes (or less), 1 = 256 bytes, 2 = 512
+bytes, 3 = 1024 bytes.
+.It Ar datalen
+The actual sector size if the size code is 0, or the (ignored) value
+0xFF for larger size codes.
+.It Ar gap
+The length of the gap 3 parameter for read/write operations.
+.It Ar ncyls
+The number of cylinders.
+.It Ar speed
+The transfer speed in kilobytes per second.
+Can be 250, 300, 500, or
+1000, but each drive type only supports a subset of these values.
+.It Ar heads
+The number of heads.
+.It Ar f_gap
+The length of the gap 3 when formatting media.
+.It Ar f_inter
+The sector interleave to be applied when formatting.
+0 means no
+interleave, 1 means 1:1 etc.
+.It Ar offs2
+The offset of the sector numbers on side 2 (i.e. head number 1).
+Normally, sector numbering on both sides starts with 1.
+.It Ar flags
+A list from one of the following flag values:
+.Pp
+.Bl -tag -width ".Cm +perpend" -compact
+.It Cm +mfm
+Use MFM encoding.
+.It Cm -mfm
+Use FM (single-density) encoding.
+.It Cm +2step
+Use 2 steps per each cylinder (for accessing 40-cylinder media in
+80-cylinder drives).
+.It Cm -2step
+Do not use 2 steps per cylinder, i.e. access each physical cylinder
+of the drive.
+.It Cm +perpend
+Use perpendicular recording (for 2.88 MB media, currently not
+supported).
+.It Cm -perpend
+Use longitudinal recording.
+.El
+.El
+.Pp
+For any missing parameter, the current value will be used, so only
+actual changes need to be specified.
+Thus to turn off a flag bit
+(like
+.Cm +mfm
+which is the default for all drive types), the form with a leading
+minus sign must explicitly be used.
+.Sh EXAMPLES
+A simple inquiry about the drive type:
+.Bd -literal
+$ fdcontrol /dev/fd0
+1.44M
+.Ed
+.Pp
+Same as above, but with verbose output.
+Note that the result is about
+the
+.Em "drive type" ,
+as opposed to a
+.Em "device density" ,
+so it is independent from the actual subdevice being used for
+.Ar device .
+.Bd -literal
+$ fdcontrol -v /dev/fd1.360
+/dev/fd1.360: 1.2M drive (5.25" high-density)
+.Ed
+.\" " <- this one is for Emacs :)
+.Pp
+Inquiry about the density settings of a particular subdevice.
+.Bd -literal
+$ fdcontrol -F /dev/fd0.720
+18,512,0xff,0x1b,80,500,2,0x6c,1,0,+mfm
+.Ed
+.Pp
+Note that just accessing a new subdevice for the first time will clone
+this device using the default density settings for the drive type, as
+explained in
+.Xr fdc 4 .
+Thus, albeit the device name in the example above suggests a 720 KB
+media density, it has actually been initialized (by the driver) to
+1440 KB.
+So, in order to adjust it for standard 720 KB double-density
+media, one of the following
+.Nm
+commands needs to be run:
+.Bd -literal
+# fdcontrol -s 9,,,0x20,,250,,0x50 /dev/fd0.720
+# fdcontrol -f 720 /dev/fd0.720
+.Ed
+.Pp
+As indicated, trailing commas in the parameter list may be omitted.
+.Pp
+In order to access archaic 160 KB single-density (FM encoded) 5.25
+media in a modern 1.2M drive, something like the following definition
+would be needed.
+(Note that not all controller hardware is actually
+capable of handling FM encoding at all.)
+.Bd -literal
+# fdcontrol -s 16,128,0x80,0x2,40,300,,0x10,,,-mfm,+2step /dev/fd1.1

+.Sh NAME
+.Nm fdformat
+.Nd format floppy disks
+.Sh SYNOPSIS
+.Nm
+.Op Fl F Ar fill
+.Op Fl f Ar fmt
+.Op Fl s Ar fmtstr
+.Op Fl nqvy
+.Ar device
+.Sh DESCRIPTION
+The
+.Nm
+utility formats a floppy disk at
+.Ar device ,
+where
+.Ar device
+may either be given as a full path
+name of a device node for a floppy disk drive
+(e.g.\&
+.Pa /dev/fd0 ) ,
+or using an abbreviated name that will be looked up
+under
+.Pa /dev
+(e.g.\&
+.Dq Li fd0 ) .
+.Pp
+The options are as follows:
+.Bl -tag -width ".Fl s Ar fmtstr"
+.It Fl F Ar fill
+Use
+.Ar fill
+as the fill byte for newly formatted sectors.
+.Ar fill
+must be a number in the range 0 through 255 using common C
+language notation.
+The default value is
+.Dq Li 0xf5 .
+.It Fl f Ar fmt
+Specify the density settings for a
+.Ar fmt
+kilobyte format, as described in
+.Xr fdcontrol 8 .
+.It Fl s Ar fmtstr
+Specify the density settings using explicit parameters, as
+described in
+.Xr fdcontrol 8 .
+.It Fl n
+Do not verify floppy after formatting.
+.It Fl q
+Suppress any normal output from the command, and do not ask the
+user for a confirmation whether to format the floppy disk at
+.Ar device .
+.It Fl v
+Do not format, verify only.
+.It Fl y
+Do not ask for confirmation whether to format the floppy disk but
+still report formatting status.
+.El
+.Pp
+For non-autoselecting subdevices, neither
+.Fl f Ar fmt
+nor
+.Fl s Ar fmtstr
+may be specified, since the preconfigured media density settings
+from the kernel driver will always be used.
+However, if
+.Ar device
+is a device with automatic media density selection (see
+.Xr fdc 4 ) ,
+both methods can be used to override the density settings for the
+newly formatted medium (without permanently changing the density
+settings of
+.Ar device ) .
+.Pp
+If the
+.Fl q
+flag has not been specified, the user is asked for a confirmation
+of the intended formatting process.
+In order to continue, an answer
+of
+.Ql y
+must be given.
+.Pp
+Note that
+.Nm
+does only perform low-level formatting.
+In order to create
+a file system on the medium, see the commands
+.Xr newfs 8
+for a
+.Tn UFS
+file system, or
+.Xr newfs_msdos 8
+for an
+.Tn MS-DOS
+(FAT)
+file system.
+.Sh DIAGNOSTICS
+Unless
+.Fl q
+has been specified, a single letter is printed to standard output
+to inform the user about the progress of work.
+First, an
+.Ql F
+is printed when the track is being formatted, then a
+.Ql V
+while it is being verified, and if an error has been detected, it
+will finally change to
+.Ql E .
+Detailed status information (cylinder, head and sector number, and the
+exact cause of the error) will be printed for up to 10 errors after the
+entire formatting process has completed.
+.Sh DIAGNOSTICS
+An exit status of 0 is returned upon successful operation.
+Exit status
+1 is returned on any errors during floppy formatting, and an exit status
+of 2 reflects invalid arguments given to the program (along with an
+appropriate information written to diagnostic output).
+.Sh SEE ALSO
+.Xr fdc 4 ,
+.Xr fdcontrol 8 ,
+.Xr newfs 8 ,
+.Xr newfs_msdos 8
+.Sh HISTORY
+The
+.Nm
+utility
+has been developed for
+.Bx 386 0.1
+and upgraded to the new
+.Xr fdc 4
+floppy disk driver.
+It later became part of the
+.Fx 1.1
+system.
+Starting with
+.Fx 5.0 ,
+it uses the unified density specifications as described in
+.Xr fdcontrol 8 .

+.Sh NAME
+.Nm fdread
+.Nd read floppy disks
+.Sh SYNOPSIS
+.Nm
+.Op Fl qr
+.Op Fl d Ar device
+.Op Fl f Ar fillbyte
+.Op Fl o Ar file
+.Nm
+.Op Fl d Ar device
+.Fl I Ar numsects
+.Op Fl t Ar trackno
+.Sh DESCRIPTION
+The
+.Nm
+utility reads floppy disks.  Effective read blocking based on the track
+size is performed, and floppy-specific error recovery of otherwise
+bad blocks can be enabled.
+.Pp
+The
+.Nm
+utility
+will always read an entire floppy medium, and write its contents to
+the respective output file.  Unlike other tools like
+.Xr dd 1 ,
+.Nm
+automatically uses a read block size that is more efficient than
+reading single blocks (usually one track of data at a time), but
+falls back to reading single floppy sectors in case of an input/output
+error occurred, in order to obtain as much valid data as possible.
+While
+.Nm
+is working, kernel error reporting for floppy errors is turned off, so
+the console and/or syslog are not flooded with kernel error messages.
+.Pp
+The
+.Nm
+utility accepts the following options:
+.Bl -tag -width indent
+.It Fl q
+Turn on quiet mode.  By default, the medium parameters of the device
+are being written to standard error output, progress will be indicated
+by the approximate number of kilobytes read so far, and errors will be
+printed out in detail, including the information about the location of
+recovered data in the output.  In quiet mode, none of these messages
+will be generated.
+.It Fl r
+Enable error recovery.  By default,
+.Nm
+stops after the first unrecovered read error, much like
+.Xr dd 1
+does.  In recovery mode, however, one of two recovery actions will be
+taken:
+.Bl -bullet
+.It
+If the error was a CRC error in the data field, the
+kernel is told to ignore the error, and data are transferred to the
+output file anyway.
+.Bf -emphasis
+Note that this will cause the erroneous data
+to be included in the output file!
+.Ef
+Still, this is the best recovery action that can be taken at all.
+.It
+All other errors are really fatal (usually, the FDC didn't find the
+sector ID fields), thus a dummy block with fill
+bytes will be included in the output file.
+.El
+.Pp
+Unless operating in quiet mode, the action taken and the location of
+the error in the output file will be displayed.
+.It Fl d Ar device
+Specify the input floppy device, defaulting to
+.Pa /dev/fd0 .
+The parameter
+.Ar device
+must be a valid floppy disk device.
+.It Fl f Ar fillbyte
+Value of the fill byte used for dummy blocks in the output file in
+recovery mode.  Defaults to
+.Ql 0xf0 .
+(Mnemonic:
+.Dq foo . )
+The value can be specified using the usual C language notation of
+the number base.
+.It Fl o Ar file
+Specify the output file to be
+.Ar file .
+By default, the data will be written to standard output.
+.It Fl I Ar numsects
+Read
+.Ar numsects
+sector ID fields, and write out their contents to standard output.
+Each sector ID field contains recorded values for the cylinder number
+.Pq Ql C ,
+the head number
+.Pq Ql H ,
+the record number (sector number starting with 1)
+.Pq Ql R ,
+and the
+.Em sector shift value
+(0 = 128 bytes, 1 = 256 bytes, 2 = 512 bytes, 3 = 1024 bytes)
+.Pq Ql N .
+The
+.Fl I
+option is mutually exclusive with all other options except
+.Fl d Ar device
+and
+.Fl t Ar trackno .
+.It Fl t Ar trackno
+Specify the track number (cylinder number * number of heads + head
+number) to read the sector ID fields from; only allowed together with
+the
+.Fl I Ar numsects
+option.
+.El
+.Sh FILES
+.Bl -tag -width /dev/fd0
+.It Pa /dev/fd0
+Default device to read from.
+.El
+.Sh DIAGNOSTICS
+The
+.Nm
+utility sets the exit value according to
+.Xr sysexits 3 .
+In recovery mode, the exit value will be set to
+.Dv EX_IOERR
+if any error occurred during processing (even in quiet mode).
+.Pp
+Unless running in quiet mode, upon encountering an error, the status
+of the floppy disc controller (FDC) will be printed out, both in
+hexadecimal form, followed by a textual description that translates
+those values into a human-readable form for the most common error
+cases that can happen in a PC environment.
+.Pp
+The FDC error status includes the three FDC status registers
+.Ql ST0 ,
+.Ql ST1 ,
+and
+.Ql ST2 ,
+as well as the location of the error (physical cylinder, head, and sector
+number, plus the
+.Dq sector shift value ,
+respectively).  See the manual for the NE765 or compatible for details
+about the status register contents.
+.Pp
+The FDC's status is then examined to determine whether the error is
+deemed to be recoverable.  If error recovery was requested, the
+location of the bad block in the output file is indicated by its
+(hexadecimal) bounds.  Also, a summary line indicating the total number
+of transfer errors will be printed before exiting.
+.Sh SEE ALSO
+.Xr dd 1 ,
+.Xr fdwrite 1 ,
+.Xr sysexits 3 ,
+.Xr fdc 4 ,
+.Xr fdcontrol 8
+.Sh HISTORY
+The
+.Nm
+utility was written mainly to provide a means of recovering at least some of
+the data on bad media, and to obviate the need to invoke
+.Xr dd 1
+with too many hard to memorize options that might be useful to handle
+a floppy.
+.Pp
+The command appeared in
+.Fx 5.0 .
+.Sh AUTHORS
+Program and man page by
+.An J\(:org Wunsch .
+.Sh BUGS
+Concurrent traffic on the second floppy drive located at the same FDC
+will make error recovery attempts pointless, since the FDC status
+obtained after a read error occurred cannot be guaranteed to actually
+belong to the erroneous transfer.  Thus using option
+.Fl r
+is only reliable if
+.Ar device
+is the only active drive on that controller.
+.Pp
+No attempt beyond the floppy error retry mechanism of
+.Xr fdc 4
+is made in order to see whether bad sectors could still be read
+without errors by trying multiple times.
+.Pp
+Bits that are (no longer) available on the floppy medium cannot be
+guessed by
+.Nm .

+.Sh NAME
+.Nm fdwrite
+.Nd format and write floppy disks
+.Sh SYNOPSIS
+.Nm
+.Op Fl v
+.Op Fl y
+.Op Fl f Ar inputfile
+.Op Fl d Ar device
+.Sh DESCRIPTION
+The
+.Nm
+utility formats and writes one and more floppy disks.
+Any floppy disk device capable of formatting can be used.
+.Pp
+The
+.Nm
+utility will ask the user
+(on
+.Pa /dev/tty )
+to insert a new floppy and press return.
+The device will then be opened, and queried for its parameters,
+then each track will be formatted, written with data from the
+.Ar inputfile ,
+read back and compared.
+When the floppy disk is filled, the process is repeated, with the next disk.
+This continues until the program is interrupted or EOF is encountered on the
+.Ar inputfile .
+.Pp
+The options are as follows:
+.Bl -tag -width 10n -offset indent
+.It Fl v
+Toggle verbosity on stdout.
+Default is ``on''.
+After
+.Ar device
+is opened first time the format will be printed.
+During operation progress will be reported with the number of tracks
+remaining on the current floppy disk, and the letters I, Z, F, W,
+R and C, which indicates completion of Input, Zero-fill, Format
+Write, Read and Compare of current track respectively.
+.It Fl y
+Don't ask for presence of a floppy disk in the drive.
+This non-interactive flag
+is useful for shell scripts.
+.It Fl f Ar inputfile
+Input file to read.  If none is given, stdin is assumed.
+.It Fl d Ar device
+The name of the floppy device to write to.  Default is
+.Pa /dev/fd0 .
+.El
+.Pp
+The
+.Nm
+utility actually closes the
+.Ar device
+while it waits for the user to press return,
+it is thus quite possible to use the drive for other purposes at this
+time and later resume writing with the next floppy.
+.Pp
+The parameters returned from
+.Ar device
+are used for formatting.
+If custom formatting is needed, please use
+.Xr fdformat 1
+instead.
+.Sh EXAMPLES
+The
+.Nm
+utility
+was planned as a tool to make life easier when writing a set of floppies,
+one such use could be to write a tar-archive:
+.Pp
+.Dl "tar cf - . | gzip -9 | fdwrite -d /dev/fd0.1720 -v
+.Pp
+The main difference from using
+.Xr tar 1 Ns 's
+multivolume facility is of course the formatting of the floppies, which
+here is done on the fly,
+thus reducing the amount of work for the floppy-jockey.
+.Sh SEE ALSO
+.Xr fdformat 1
+.Sh HISTORY
+The
+.Nm
+utility was written while waiting for ``make world'' to complete.
+Some of the code was taken from
+.Xr fdformat 1 .
+.Sh AUTHORS
+The program has been contributed by
+.An Poul-Henning Kamp Aq phk@FreeBSD.org .
+.Sh BUGS
+Diagnostics are less than complete at present.
+.Pp
+If a floppy is sick, and the
+.Ar inputfile
+is seekable, it should ask the user to frisbee the disk, insert
+another, and rewind to the right spot and continue.
+.Pp
+This concept could be extended to cover non-seekable input also
+by employing a temporary file.
+.Pp
+An option (defaulting to zero) should allow the user to ask for
+retries in case of failure.
+.Pp
+At present a suitable tool for reading back a multivolume set
+of floppies is missing.
+Programs like
+.Xr tar 1
+for instance, will do the job, if the data has not been compressed.
+One can always trust
+.Xr dd 1
+to help out in this situation of course.

+.Sh NAME
+.Nm getextattr
+.Nd retrieve a named extended attribute
+.Sh SYNOPSIS
+.Nm
+.Op Fl ls
+.Ar attrnamespace
+.Ar attrname
+.Ar filename ...
+.Sh DESCRIPTION
+.Nm
+is a user tool to retrieve a named extended attribute on a file or
+directory.
+The
+.Ar attrnamespace
+argument should be the namespace of the attribute to retrieve: legal
+values are "user" and "system".
+The
+.Ar attrname
+argument should be the name of the attribute, and
+.Ar filename
+a list of files and directories from which to retrieve attribute data.
+.Pp
+The following options are available:
+.Bl -tag -width indent
+.It Fl l
+Print attributes in the first column and file names in the second.
+Can be used only in conjunction with the
+.Fl s
+option.
+.It Fl s
+Attempt to display the attribute data as a string, although the
+results may not look pretty if the data is binary data.
+The
+.Xr strvisx 3
+function is used to generate the string, so control sequences should
+be safely escaped.
+Otherwise, the attribute data will be represented as a series of two-digit
+hex numbers.
+.El
+.Sh IMPLEMENTATION NOTES
+In order for
+.Nm
+to succeed, the attribute service must be available on the file system,
+and the attribute must of defined for the file queried.
+.Sh EXAMPLES
+.Bd -literal -offset indent
+# getextattr system md5 /boot/kernel/kernel
+/boot/kernel/kernel:
+  61 61 33 62 39 39 66 65    31 35 35 32 31 62 65 32
+  62 36 38 36 62 31 66 39    63 64 33 39 35 36 36 31

+.Sh SEE ALSO
+.Xr extattr 2 ,
+.Xr extattr 3 ,
+.Xr extattrctl 8 ,
+.Xr setextattr 8 ,
+.Xr extattr 9
+.Sh HISTORY
+Extended attribute support was developed as part of the TrustedBSD Project,
+and introduced in
+.Fx 5.0 .
+It was developed to support security extensions requiring additional labels
+to be associated with each file or directory.
+.Sh AUTHORS
+Robert N M Watson
+.Sh BUGS
+The output format for this utility is ugly, and worse yet, not very useful.

+.Dt GIFCONFIG 8
+.Os
+.Sh NAME
+.Nm gifconfig
+.Nd configure generic IP tunnel
+.\"
+.Sh SYNOPSIS
+.Nm
+.Ar interface
+.Op Ar af
+.Op Ar physsrc physdest
+.Nm
+.Ar interface
+.Ic delete
+.Nm
+.Fl a
+.Sh DESCRIPTION
+.Nm
+configures the physical address for the generic IP tunnel
+inteface, such as "gif0".
+Argument
+.Ar physsrc
+and
+.Ar physdest
+are interpreted as the outer source/destination address for
+encapsulating IPv4/v6 header.
+Argument
+.Ar af
+specifies the address family for
+.Ar physsrc
+and
+.Ar physdest .
+.Ar af
+can be
+.Li inet
+or
+.Li inet6 ,
+and will be treated as
+.Li inet
+if ommitted.
+.Pp
+If a special argument
+.Ic delete
+is specified,
+.Nm
+just deletes the existing source and destination addresses on
+.Ar interface .
+If no outer addresses are specified, this usage has no effect.
+.Pp
+.Nm
+takes the following optional argument:
+.Bl -tag -width Ds
+.It Fl a
+Display information associated with all
+.Xr gif 4
+interfaces.
+.El
+.Pp
+Please note that it is very easy to create infinite routing loop,
+when you configure tunnel over same address family
+(e.g. IPv4-over-IPv4).
+.Pp
+Each
+.Xr gif 4
+interface is created at runtime using interface cloning.
+This is
+most easily done with the
+.Xr ifconfig 8
+.Cm create
+command or using the
+.Va gifconfig_ Ns Aq Ar interface
+variable in
+.Xr rc.conf 5 .
+.Sh EXAMPLES
+If you would like to configure IPv6 over IPv4
+(aka IPv6 in IPv4)
+tunnel between
+.Li 10.1.1.1
+and
+.Li 10.2.3.4 ,
+you should perform the following command:
+.Bd -literal -offset
+# gifconfig gif0 inet 10.1.1.1 10.2.3.4
+.Ed
+.Pp
+.\" To use the
+.\" .Li 0.0.0.0
+.\" feature to establish a tunnel from host1 to host3
+.\" which will encapsulate and carry packets from host2, on host1 do:
+.\" .Bd -literal -offset
+.\" # ifconfig gif0 inet host1  127.0.0.2  # assign an address to gif0
+.\" # gifconfig gif0 inet host1 0.0.0.0    # assign encapsulation addresses
+.\" # route add host2 host3 -ifp gif0:     # encap host2 packets, send to host3
+.\" .Ed
+.\" .Pp
+.\" Note: the
+.\" .Fl ifp
+.\" option to route does not work as documented in
+.\" most versions of FreeBSD.
+.\" .Pp
+.\" On host3 do:
+.\" .Bd -literal -offset
+.\" # ifconfig gif0 inet host3  127.0.0.2  # assign an address to gif0
+.\" # gifconfig gif0 inet host3 0.0.0.0    # assign encapsulation addresses
+.\" .Ed
+.\" .Pp
+.\" Now if you ping host2 from host1, the packets should be encapsulated
+.\" with outer source address = host1 and outer destination address = host3,
+.\" and delivered to host3.
+.\" host3 will decapsulate the packet and deliver it normally to host2.
+.\" .Pp
+This is also possible to use IPv6 as outer proto, by replacing
+.Li inet
+to
+.Li inet6 ,
+and IPv4 addresses to some appropriate IPv6 addresses in above example.
+.Sh RETURN VALUES
+The command exits with exit status of 1 on errors, 0 on success.
+.Sh SEE ALSO
+.Xr gif 4 ,
+.Xr ifconfig 8
+.Sh HISTORY
+The
+.Nm
+command first appeared in WIDE Hydrangea IPv6 protocol stack kit.
+.Pp
+IPv6 and IPsec support based on the KAME Project (http://www.kame.net/) stack
+was initially integrated into
+.Fx 4.0

+.Os
+.Sh NAME
+.Nm dtmfdecode
+.Nd decodes DTMF tones from A-law audio data
+.Sh SYNOPSIS
+.Nm
+.Sh DESCRIPTION
+The
+.Nm
+utility
+is part of the isdn4bsd package and is used to detect DTMF tones in the
+audio stream.
+.Pp
+It reads audio G.711 A-Law coded data from stdin and outputs the detected
+numbers values as ASCII charcters to stdout.
+.Pp
+The detector is implemented as 8 narrow band-pass filters realized with
+an integer double-cross recursive algorithm.  Various ad-hoc methods are
+employed to provide hysteresis and anti-bounce for the detected signals.
+.Sh EXAMPLES
+The command:
+.Bd -literal -offset indent
+dtmfdecode < beep.al
+.Ed
+.Pp
+will print a "1" to stdout.
+.Sh STANDARDS
+ITU Recommendations G.711
+.Sh AUTHORS
+.An -nosplit
+The
+.Nm
+utility was written by
+.An Poul-Henning Kamp Aq phk@FreeBSD.org .
+This man page was written by
+.An Hellmuth Michaelis Aq hm@FreeBSD.org .

+.Sh NAME
+.Nm g711conv
+.Nd conversions according to G.711
+.Sh SYNOPSIS
+.Nm
+.Op Fl a
+.Op Fl u
+.Op Fl P
+.Op Fl A
+.Op Fl R
+.Sh DESCRIPTION
+The
+.Nm
+utility
+is part of the isdn4bsd package and is used to convert between the A-Law and
+u-law formats as specified in ITU G.711. It is based on a freely available
+and freely usable reference implementation done by Sun Microsystems, Inc.
+.Pp
+The following options are available:
+.Bl -tag -width Ds
+.It Fl a
+Convert A-law to u-law
+.It Fl u
+Convert u-law to A-law
+.It Fl r
+Reverse bits before conversion
+.It Fl R
+Reverse bits after conversion
+.It Fl P
+Print the resulting conversion tables (as C-source) to stdout instead of
+doing the actual conversion.
+.El
+.Sh STANDARDS
+A-Law and u-Law conversions are specified in ITU Recommendation G.711.
+.Pp
+The reference implementation done by Sun Microsystems, Inc. is available
+from http://www.itu.int/itudoc/itu-t/rec/g/g700-799/refimpl.txt
+.Sh EXAMPLES
+The command:
+.Bd -literal -offset indent
+g711conv -P -a
+.Ed
+.Pp
+prints out the A-law to u-law conversion table as C-source to stdout.
+.Pp
+The command:
+.Bd -literal -offset indent
+cat max_headroom.ul | g711conv -u -R > /dev/i4btel0
+.Ed
+.Pp
+converts the u-law coded voice of Max Headroom to A-law, reverses the
+bits of the result and moves that to an active isdn4bsd telephone connection.
+.Sh AUTHORS
+The
+.Nm
+utility and this manpage were written by
+.An Hellmuth Michaelis Aq hm@kts.org
+based on the G.711 conversion reference code written by Sun Microsystems,
+Inc. and code contributed to isdn4bsd by Stefan Bethke.

+.Nm isdnd
+.Nd isdn4bsd ISDN connection management daemon
+.Sh SYNOPSIS
+.Nm
+.Op Fl c Ar configfile
+.Op Fl d Ar debuglevel
+.Op Fl f
+.Op Fl F
+.Op Fl l
+.Op Fl L Ar logfile
+.Op Fl P
+.Op Fl r Ar device
+.Op Fl s Ar facility
+.Op Fl t Ar terminaltype
+.Op Fl u Ar charging unit length
+.Op Fl m
+.Sh DESCRIPTION
+.Nm Isdnd
+is the isdn4bsd package daemon which manages all ISDN related connection
+and disconnection of ISDN devices supported by the package.
+.Pp
+The options are as follows:
+.Bl -tag -width Ds
+.It Fl c
+Use
+.Ar configfile
+as the name of the runtime configuration filename for
+.Nm
+instead of the default file
+.Li /etc/isdn/isdnd.rc .
+.It Fl d
+If debugging support is compiled into
+.Nm
+this option is used to specify the debugging level, or better which kind
+of debugging messages are displayed.
+The debugging level is the sum of the
+following values:
+.Pp
+.Bl -tag -width Ds -compact -offset indent
+.It Ar 0x001
+general debugging.
+.It Ar 0x002
+rates calculation.
+.It Ar 0x004
+timing calculations.
+.It Ar 0x008
+state transitions.
+.It Ar 0x010
+retry handling.
+.It Ar 0x020
+dialing.
+.It Ar 0x040
+process handling.
+.It Ar 0x080
+isdn4bsd kernel i/o calls.
+.It Ar 0x100
+controller and channel busy/free messages.
+.It Ar 0x200
+isdnd.rc configuration file processing.
+.It Ar 0x400
+outgoing call budget handling.
+.It Ar 0x800
+valid keyword and holiday file processing.
+.El
+.Pp
+The value can be specified in any number base supported by the
+.Xr sscanf 3
+library routine.
+.Pp
+In addition, this option accepts also the character 'n' as an argument to
+disable displaying debug messages on the full-screen display.
+.Pp
+.It Fl f
+Specifying this option causes
+.Nm
+to enter the full-screen mode of operation.
+When operating in this mode,
+entering the control character
+.Em Control-L
+causes the display to be refreshed and entering
+.Em Carriage-Return
+or
+.Em Enter
+will pop-up a command window.
+Because the
+.Nm
+daemon will not listen to messages while the command window is active,
+this command window will disappear automatically after 5 seconds without
+any command key press.
+.Pp
+While the command window is active,
+.Em Tab
+or
+.Em Space
+advances to the next menu item.
+To execute a command, press
+.Em Return
+or
+.Em Enter
+for the highlighted menu item, or enter the number corresponding to the
+item to be executed or enter the capitalized character in the menu item
+description.
+.It Fl l
+If this option is set, logging is not done via the
+.Xr syslogd 8
+facility but instead is appended to a file.
+.It Fl L
+Specifies the name of the logfile which is used when the option
+.Em -l
+is set.
+See also the keyword
+.Em rotatesuffix
+in the system section of
+.Xr isdnd.rc 5 .
+.It Fl P
+This option prints out the parsed and verified isdnd configuration in the same
+format as the isdnd.rc file.
+This output can be used as an isdnd.rc file.
+This
+feature is especially useful when debugging an isdnd.rc file to see, what the
+default settings of options are when they are not set in the isdnd.rc input
+file.
+.Pp
+The
+.Nm
+exits after the printout is done.
+.It Fl F
+This option prevents
+.Nm
+to detach from the controlling tty and become a daemon.
+.It Fl r
+In conjunction with the
+.Fl t
+option,
+.Ar device
+specifies a terminal device which becomes the controlling tty for
+.Nm
+and on which the full-screen mode output is displayed.
+.It Fl s
+This option may be used to specify the logging facility in case
+.Xr syslog 3
+logging is configured and another facility than the default LOCAL0
+facility shall be used.
+The facility is to be specified as an integer in
+the range 0-11 or 16-23 (see the file /usr/include/syslog.h).
+.It Fl t
+In conjunction with the
+.Fl f
+and
+.Fl r
+options,
+.Ar terminaltype
+specifies a terminal type or termcap entry name (such as vt220) for the device
+used for
+.Nm
+full-screen output.
+This is useful if an unused (no getty running) tty line is
+used for full-screen output for which no
+.Li TERM
+environment variable exists.
+.It Fl u
+Specifies the length of a charging unit in case the config file entry
+keyword
+.Em unitlenghtsrc
+is set to
+.Em cmdl .

+.El
+.Sh INTERACTION WITH THE KERNEL
+.Nm Isdnd
+communicates with the kernel part of isdn4bsd by receiving status and
+event messages
+.Xr ( read 2
+from device
+.Pa /dev/i4b )
+and by transmitting commands and responses
+.Xr ( ioctl 2
+from device
+.Pa /dev/i4b ) .
+.Pp
+The messages and message parameters are documented in the include
+file
+.Em /usr/include/machine/i4b_ioctl.h .
+.Pp
+Supported command and response messages (ioctls) to the kernel are:
+.Bl -tag -width Ds -compact -offset indent
+.It Ar I4B_CDID_REQ
+Request a unique Call Description IDentifier (cdid) which identifies
+uniquely a single interaction of the local D channel with the exchange.
+.It Ar I4B_CONNECT_REQ
+Actively request a call setup to a remote ISDN subscriber.
+.It Ar I4B_CONNECT_RESP
+Respond to an incoming call, either accept, reject or ignore it.
+.It Ar I4B_DISCONNECT_REQ
+Actively terminate a connection.
+.It Ar I4B_CTRL_INFO_REQ
+Request information about an installed ISDN controller card.
+.It Ar I4B_DIALOUT_RESP
+Give information about call setup to driver who requested dialing out.
+.It Ar I4B_TIMEOUT_UPD
+Update the kernels timeout value(s) in case of dynamically calculated
+shorthold mode timing changes.
+.It Ar I4B_UPDOWN_IND
+Inform the kernel userland drivers about interface soft up/down status
+changes.
+.It Ar I4B_CTRL_DOWNLOAD
+Download firmware to active card(s).
+.It Ar I4B_ACTIVE_DIAGNOSTIC
+Return diagnostic information from active cards.
+.El
+.Pp
+.Pp
+Supported status and event messages from the kernel are:
+.Bl -tag -width Ds -compact -offset indent
+.It Ar MSG_CONNECT_IND
+An incoming call from a remote ISDN user is indicated.
+.It Ar MSG_CONNECT_ACTIVE_IND
+After an incoming call has been accepted locally or an outgoing call has
+been accepted by a remote, the exchange signaled an active connection
+and the corresponding B-channel is switched through.
+.It Ar MSG_DISCONNECT_IND
+A call was terminated.
+.It Ar MSG_DIALOUT_IND
+A userland interface driver requests the daemon to dial out (typically a
+network interface when a packet arrives in its send queue).
+.It Ar MSG_IDLE_TIMEOUT_IND
+A call was terminated by the isdn4bsd kernel driver because a B-channel
+idle timeout occurred.
+.It Ar MSG_ACCT_IND
+Accounting information from a network driver.
+.It Ar MSG_CHARGING_IND
+Charging information from the kernel.
+.El
+.Pp
+.Ss OUTGOING CALLS
+Currently the only possibility to trigger an outgoing call is that an
+isdn4bsd network driver
+.Em (ipr<n>)
+sends a
+.Em MSG_DIALOUT_IND
+to the
+.Nm
+daemon.
+.Pp
+The daemon requests a new CDID from the kernel by using the
+.Em I4B_CDID_REQ
+ioctl message, this CDID is now used in all interactions with the kernel
+to identify this single call until a disconnect occurs.
+.Pp
+After getting the CDID, the daemon looks up several additional information
+in its entry section of the configuration corresponding to that connection
+and issues a
+.Em I4B_CONNECT_REQ
+ioctl message to the kernel.
+The kernel now dials the remote side and
+if the remote side accepts the call, the kernel sends a
+.Em MSG_CONNECT_ACTIVE_IND
+to the daemon.
+.Pp
+The call is terminated by either the local side timing out or the remote
+side hanging up the connection or the local side actively sending a
+.Em I4B_DISCONNECT_REQ
+ioctl message, both events are signaled to the
+.Nm
+by the kernel sending the
+.Em I4B_DISCONNECT_IND
+message and the CDID corresponding to the call is no longer valid.
+.Pp
+.Ss INCOMING CALLS
+Incoming calls are signaled to the
+.Nm
+by the kernel transmitting the
+.Em MSG_CONNECT_IND
+message to the daemon.
+.Pp
+With the information contained in this message, the
+.Nm
+searches the entry section of its configuration database and if a match is
+found, it accepts or rejects the call or, if no match is found, it ignores the
+call - all by issuing a
+.Em I4B_CONNECT_RESP
+ioctl message with the appropriate parameters to the kernel.
+.Pp
+In case the daemon decided to accept the call, the kernel signals this
+by sending a
+.Em MSG_CONNECT_ACTIVE_IND
+message to the daemon.
+.Pp
+The call is terminated by either the local side timing out or the remote
+side hanging up the connection or the local side actively sending a
+.Em I4B_DISCONNECT_REQ
+ioctl message, both events are signaled to the
+.Nm
+by the kernel sending the
+.Em I4B_DISCONNECT_IND
+message and the CDID corresponding to the call is no longer valid.
+.Sh SIGNALS
+Sending a HUP signal to
+.Nm
+causes all open connections to be terminated and the configuration file is
+reread.
+In case aliasfile handling was enabled, the aliasfile is also
+reread.
+.Pp
+Sending a USR1 signal to
+.Nm
+causes the accounting file and the logfile (if logging to a file is used
+instead of logging via the
+.Xr syslog 3
+facility) to be closed and reopened to make logfile rotation possible.
+.Sh ENVIRONMENT
+The following environment variables affect the execution of
+.Nm :
+.Bl -tag -width Ds
+.It Ev TERM
+The terminal type when running in full-screen display mode.
+See
+.Xr environ 7
+for more information.
+.El
+.Sh FILES
+.Bl -tag -width /etc/isdn/isdnd.rates
+.It Pa /dev/i4b
+The device-file used to communicate with the kernel ISDN driver subsystem.
+.It Pa /var/log/messages
+A record of the actions in case of syslogd logging support.
+.It Pa /var/log/isdnd.acct
+The default accounting information filename (if accounting is configured).
+.It Pa /var/log/isdnd.log
+The default logging filename (if logging to a file is configured).
+.It Pa /var/run/isdnd.pid
+The process id of the isdn daemon (also known as "lockfile" to isdnd, preventing multiple invocations of it).
+.It Pa /usr/local/lib/isdn
+.It Pa /etc/isdn
+The directory where isdnd expects some supplementary data files and programs
+for telephone answering support.
+.It Pa /etc/isdn/isdnd.rc
+The default runtime configuration file.
+.It Pa /etc/isdn/isdnd.rates
+The default unit charging rates specification file.
+.It Pa /etc/isdn/isdntel.alias
+The default table (if aliasing is enabled) to convert phone number to caller's name.
+.El
+.Sh EXAMPLES
+For a first try, the following command should be used to start
+.Nm
+in foreground mode for better debugging the configuration setup:
+.Bd -literal -offset indent
+isdnd -d0xf9 -F
+.Ed
+.Pp
+This will start isdnd with reasonable debugging settings and produce
+output on the current terminal.
+.Nm Isdnd
+can then be terminated by entering Control-C.
+.Pp
+Another example, the command:
+.Bd -literal -offset indent
+isdnd -d0xf9 -f -r /dev/ttyv3 -t vt100
+.Ed
+.Pp
+will start
+.Nm
+with reasonable debugging messages enabled, full-screen mode of operation,
+full-screen display redirected to /dev/ttyv3 and using a termcap entry
+for vt100 on this display.
+.Sh DIAGNOSTICS
+Exit status is 0 on success, 1 on error.

+The file
+.Pa isdnd.acct
+contains accounting information which is written if the variable
+.Em useacctfile
+in the
+.Xr isdnd 8
+configuration file
+.Xr isdnd.rc 5
+is set to
+.Em on
+and charging information transmission has been subscribed for the
+ISDN connection (AOCD or AOCE).
+.Pp
+If the variable
+.Em acctall
+is set to

+accounting information is written even if the local site was not charged
+or no charging information is available or is not subscribed.
+.Pp
+The general format of an accounting line is as follows:
+.Pp
+.Dl FROM - UNTIL NAME UNITS (SECONDS) (INBYTES/OUTBYTES)
+.Pp
+.Em FROM
+is the time the connection was established in the format
+.Dl Day.Month.Year Hour:Minutes:seconds
+.Pp
+.Em UNTIL
+is the time the connection was closed. The format is the same as
+described for
+.Em FROM
+above.
+.Pp
+.Em NAME
+is the symbolic name got from the
+.Em name
+entry of the
+.Xr isdnd.rc 5
+config file for this connection.
+.Pp
+.Em UNITS
+is the amount of charging units billed for the connection.
+.Pp
+.Em SECONDS
+is the number of seconds the connection lasted.
+.Pp
+.Em INBYTES
+and
+.Em OUTBYTES
+is the (optional) number of bytes that were transferred.

+.Xr isdnd 8
+ISDN connection management daemon to calculate the short hold time for a
+connection.
+.Pp
+The format of a rate entry line is as follows:
+.Pp
+The first field, the
+.Pq Fa rate-code
+defines a collection of rates (for each day of the week) which can be
+referenced in the
+.Xr isdnd 8
+configuration file
+.Xr isdnd.rc 5 .
+This field must start with the identifier
+.Dq ra
+followed by a digit in the range of zero to four.
+.Pp
+The second field, the
+.Pq Fa day-number
+selects the day of week for which this entry defines the rates, where 0 stands
+for Sunday, 1 for Monday and so on until the digit 6 which stands for Saturday.
+.Pp
+The rest of the line consists of one or more space separated fields which have
+the following syntax:
+.Bd -ragged -offset indent
+start_hour.start_minutes-end_hour.end_minutes:charge_unit_length
+.Ed
+.Pp
+Start_hour and start_minutes define the begin of a time section and end_hour
+and end_minutes define the end. Charge_unit_length define the length of a
+charging unit in the previously defined time section. No spaces or tabs are
+allowed inside this field. The hour and minutes specifications MUST have
+exactly 2 digits, in case just one digit is needed, a leading 0 must be used.
+.Pp
+For example,
+.Bd -ragged -offset indent
+14.00-18.00:90
+.Ed
+.Pp
+defines, that between 2:00 PM and 6:00 PM the length of one charging unit
+lasts 90 seconds.

+.Bl -tag -width "incoming calls
+.It Li incoming calls
+It is assumed that the calling side knows most about charging structures and
+such and as a consequence only the keyword
+.Em idletime-incoming
+has a function for incoming calls.
+.Pp
+For incoming calls the line is constantly monitored, and in case there was
+not traffic taking place for the time in seconds specified by
+.Em idletime-incoming
+the call is closed.
+.Pp
+Typically,
+.Em idletime-incoming
+is used as a last resort and is therefore set much higher than a charging
+unit time: typical values are one to five minutes.
+.It Li outgoing calls
+Outgoing call disconnect time can be setup in one of three ways:
+.Bl -tag -width "shorthold mode
+.It Li simple mode
+For simple mode, the
+.Em idle-algorithm-outgoing
+must be
+.Em fix-unit-size
+and the selected
+.Em unitlength

+.Em idletime-outgoing
+greater zero.
+.Pp
+The outgoing traffic is constantly monitored, and in case there was
+not traffic taking place for the time in seconds specified by
+.Em idletime-outgoing
+the call is closed.
+.Pp
+Typical values in simple mode are 10 to 30 seconds.

+For shorthold mode, the
+.Em idle-algorithm-outgoing
+must be
+.Em fix-unit-size
+and the selected
+.Em unitlength

+must be greater than 0 (zero);
+.Em earlyhangup
+must be >= 0 (zero).

+|<--------------unitlength--------------------->|
+.Ed
+.Pp
+During the unchecked window which is (unitlength - (idle-time+earlyhangup))
+in length, no idle check is done.
+After the unchecked window has ended,
+the line is checked for idle-time length if no traffic takes place.
+In case
+there was traffic detected in the check-window, the same procedure is restarted
+at the beginning of the next unit.
+In case no traffic was detected during
+the check-window, the line is closed at the end of the check window.
+.Pp
+Notice:
+.Em unitlength
+must (!) be greater than the sum of
+.Em idletime-outgoing
+and
+.Em earlyhangup !
+.It Li shorthold mode for variable unit charging
+For shorthold mode, the
+.Em idle-algorithm-outgoing
+must be
+.Em var-unit-size
+and the selected
+.Em unitlength
+and
+.Em idletime-outgoing
+must be greater than 0 (zero);
+.Pp
+This shorthold mode is suitable when your calls are billed on
+the elapse time of the call plus a fixed connection charge.
+For example British Telecom bill this way.
+.Pp
+Each call is divided into two periods, the first is the
+.Em unchecked
+period and the second is the
+.Em checked .
+The
+.Em checked
+period starts 1 second before the first units time expires.
+.Pp
+During the
+.Em checked
+period if there is no traffic for
+.Em idle-time
+seconds the call is disconnected.

+.Pp
+Experience shows that useful values for idle-time are from 15 to 30 seconds.

+.Op Fl r
+.Op Fl s Ar value
+.Op Fl u Ar unit
+.Op Fl z
+.Op Fl C
+.Op Fl Q
+.Sh DESCRIPTION
+.Nm
+is part of the isdn4bsd package and is used to control the level of
+debugging output of the isdn4bsd kernel part.
+Every layer of the isdn4bsd kernel uses a debugging mask which can be
+manipulated using this utility.
+.Pp
+A second usage of
+.Nm
+is to display and reset chipset specific statistics and/or error counters
+and and to display and reset the D-channel layer 2
+(Q.921 LAPD protocol) statistics and error counters.
+.Pp
+The following options are available:
+.Bl -tag -width Ds
+.It Fl c
+Display chipset specific statistics and/or error counters.
+.It Fl e
+Set debugging mask for the selected layer(s) to display errors only.
+.It Fl g
+Get the debugging mask for the selected layer(s).
+.It Fl l
+Specify the layer for which a command applies. Default is all layers.
+.It Fl m
+Set debugging mask for the selected layer(s) to display all possible
+debugging messages (maximum output).
+.It Fl q
+Display the Q.921 (D-channel layer 2) frame receive/transmit statistics.
+.It Fl r
+Set debugging mask for the selected layer(s) to the compiled in default
+(reset).
+.It Fl s
+Set debugging mask for the selected layer(s) to value. Value can be
+specified in any number base supported by
+.Xr sscanf 3 .
+.It Fl u
+Set the unit numbers for the -c, -q, -C and -Q flags.
+.It Fl z
+Set debugging mask for the selected layer(s) to no output at all (zero).
+.It Fl H
+Reset the chipset specific statistics and/or error counters to zero.
+.It Fl Q
+Reset the Q.921 (D-channel layer 2) frame receive/transmit statistics to zero.
+.El
+.Sh FILES

+.Nm isdndecode
+.Nd isdn4bsd ISDN protocol decode utility
+.Sh SYNOPSIS
+.Nm
+.Op Fl a
+.Op Fl b
+.Op Fl d
+.Op Fl f Ar filename
+.Op Fl h
+.Op Fl i
+.Op Fl l
+.Op Fl o
+.Op Fl p Ar filename
+.Op Fl u Ar number
+.Op Fl x
+.Op Fl B
+.Op Fl P
+.Op Fl R Ar unit
+.Op Fl T Ar unit
+.Sh DESCRIPTION
+.Nm
+is part of the isdn4bsd package and is used to provide the user with a
+detailed mnemonic display of the layers 1, 2 and 3 protocol activities on
+the D channel and hex dump of the B channel(s) activities.
+.Pp
+Together with two passive supported cards and an easy to build cable it can
+also be used to monitor the complete traffic on a S0 bus providing S0 bus
+analyzer features.
+.Pp
+The
+.Nm
+utility is only available for passive supported cards.
+.Pp
+The following options can be used:
+.Bl -tag -width Ds
+.It Fl a
+Run
+.Nm
+in analyzer mode by using two passive cards and a custom cable which can
+be build as described in the file
+.Em cable.txt
+in the isdn4bsd source distribution. One card acts as a receiver for the
+transmitting direction on the S0 bus while the other card acts as a receiver
+for the receiving direction on the S0 bus. Complete traffic monitoring is
+possible using this setup.
+.It Fl b
+switch B channel tracing on (default off).
+.It Fl d
+switch D channel tracing off (default on).
+.It Fl f
+Use
+.Ar filename
+as the name of a file into which to write tracing output (default filename is
+isdndecode<n> where n is the number of the unit to decode).
+.It Fl h
+switch display of header off (default on).
+.It Fl i
+print layer 1 (I.430) INFO signals to monitor layer 1 activity (default off).
+.It Fl l
+switch displaying of Layer 2 (Q.921) frames off (default on).
+.It Fl o
+switch off writing decode output to a file (default on).
+.It Fl p
+Use
+.Ar filename
+as the name of a file used for the -B and -P options (default filename
+is isdntracebin<n> where n is the number of the unit to decode).
+.It Fl u
+Use
+.Ar number
+as the unit number of the controller card to decode (default 0).
+.It Fl x
+Decode Layer 3 packets with an unknown protocol discriminator.
+.It Fl B
+Write undecoded binary decode data to a file for later or remote
+analyzing (default off).
+.It Fl P
+Read undecoded binary decode data from file instead from device (default off).
+.It Fl R
+Use
+.Ar unit
+as the receiving interface unit number in analyze mode.
+.It Fl T
+Use
+.Ar unit
+as the transmitting interface unit number in analyze mode.
+.El
+.Pp
+When the USR1 signal is sent to a
+.Nm
+process, the currently used logfiles are reopened, so that logfile
+rotation becomes possible.
+.Pp
+The decode output should be obvious. It is very handy to have the following
+standard texts available when tracing ISDN protocols:
+.Pp
+.Bl -tag -width Ds -compact -offset indent
+.It Ar I.430
+ISDN BRI layer 1 protocol description.
+.It Ar Q.921
+ISDN D-channel layer 2 protocol description.
+.It Ar Q.931
+ISDN D-channel layer 3 protocol description.
+.El
+.Sh FILES
+.Bl -tag -width daddeldi -compact
+.It Pa /dev/i4btrc<n>
+The devicefile(s) used to get the decode messages for ISDN card unit <n>
+out of the kernel.
+.El
+.Sh EXAMPLES
+The command:
+.Bd -literal -offset indent
+isdndecode -f /var/tmp/isdn.decode
+.Ed
+.Pp
+will start D channel tracing on passive controller 0 with all except B
+channel tracing enabled and logs everything into the output file
+/var/tmp/isdn.decode.
+.Sh SEE ALSO

+.Sh NAME
+.Nm isdnmonitor
+.Nd isdn4bsd / isdnd remote monitoring tool
+.Sh SYNOPSIS
+.Nm
+.Op Fl c
+.Op Fl d Ar debuglevel
+.Op Fl f Ar filename
+.Op Fl h Ar hostspec
+.Op Fl l Ar pathname
+.Op Fl p Ar portspec
+.Sh DESCRIPTION
+.Nm Isdnmonitor
+is used to remotely monitor the operation of the isdn daemon,
+.Xr isdnd 8 ,
+which manages all ISDN related connection and disconnection of ISDN
+devices supported by the isdn4bsd package.
+.Pp
+The options are as follows:
+.Bl -tag -width Ds
+.It Fl c
+Switch to (curses-) fullscreen mode of operation. In this mode,
+.Nm
+behaves nearly exactly as
+.Xr isdnd 8
+in fullscreen mode. In fullscreen mode, entering the control character
+.Em Control-L
+causes the display to be refreshed and entering
+.Em Carriage-Return
+or
+.Em Enter
+will pop-up a command window. Because
+.Nm
+will not listen to messages while the command window is active,
+this command window will disappear automatically after 5 seconds without
+any command key press.
+.Pp
+While the command window is active,
+.Em Tab
+or
+.Em Space
+advances to the next menu item. To execute a command, press
+.Em Return
+or
+.Em Enter
+for the highlighted menu item, or enter the number corresponding to the
+item to be executed or enter the capitalized character in the menu item
+description.
+.It Fl d
+If debugging support is compiled into
+.Nm
+this option is used to specify the debugging level.
+.\" The debugging level is the sum of the
+.\" following values:
+.\" .Pp
+.\" .Bl -tag -width Ds -compact -offset indent
+.\" .It Ar 0x001
+.\" general debugging.
+.\" .It Ar 0x002
+.\" rates calculation.
+.\" .It Ar 0x004
+.\" timing calculations.
+.\" .It Ar 0x008
+.\" state transitions.
+.\" .It Ar 0x010
+.\" retry handling.
+.\" .It Ar 0x020
+.\" dialing.
+.\" .It Ar 0x040
+.\" process handling.
+.\" .It Ar 0x080
+.\" isdn4bsd kernel i/o calls.
+.\" .It Ar 0x100
+.\" controller and channel busy/free messages.
+.\" .It Ar 0x200
+.\" isdnmonitor.rc configuration file processing.
+.\" .El
+.\" .Pp
+.\" The value can be specified in any number base supported by the
+.\" .Xr sscanf 3
+.\" library routine.
+.Pp
+In addition, this option accepts also the character 'n' as an argument to
+disable displaying debug messages on the full-screen display.
+.Pp
+.It Fl f
+Specifying this option causes
+.Nm
+to write its normal output and - if enabled - debugging output to a file
+which name is specified as the argument.
+.It Fl l
+is used to specify a Unix local domain socket name to be used for communication
+between
+.Xr isdnd 8
+and
+.Nm .
+.It Fl h
+is used to specify a hostname or a dotted-quad IP address of a machine
+where an
+.Xr isdnd 8
+is running which should be monitored.
+.It Fl p
+This option may be used to specify a remote port number in conjunction
+with the
+.Fl h
+option.
+.El
+.Sh ENVIRONMENT
+The following environment variables affect the execution of
+.Nm :
+.Bl -tag -width Ds
+.It Ev TERM
+The terminal type when running in full-screen display mode.
+See
+.Xr environ 7
+for more information.
+.El
+.Sh EXAMPLES
+For a first try, the following command should be used to start
+.Nm
+to monitor a locally running isdnd:
+.Bd -literal -offset indent
+isdnmonitor -h localhost
+.Ed
+.Sh DIAGNOSTICS
+Exit status is 0 on success, 1 on error.
+.Sh SEE ALSO
+.Xr isdnd 8
+.Sh BUGS
+Still one (or) more left.

+.Sh SYNOPSIS
+.Nm
+.Op Fl a Ar aliasfile
+.Op Fl d Ar spooldir
+.Op Fl p Ar playcommand
+.Op Fl t Ar timeout
+.Sh DESCRIPTION
+.Nm
+is used to provide an "answering machine" functionality for incoming
+telephone voice messages.
+.Pp
+The following options are supported:
+.Bl -tag -width Ds
+.It Fl a
+Use
+.Ar aliasfile
+as the pathname for an aliasfile containing aliases for phone numbers. The
+default path is
+.Em /etc/isdn/isdntel.alias .
+The format of an alias entry is the number string followed by one or more
+spaces or tabs. The rest of the line is taken as the alias string. Comments
+are introduced by a leading blank, tab or "#" character.
+.It Fl d
+Use
+.Ar spooldir
+as the directory where the incoming voice messages are stored by the
+"answ" script called by
+.Xr isdnd 8 .
+This defaults to the directory
+.Em /var/isdn .
+The format of a voice message filename is:
+.Pp
+.Dl YYMMDDhhmmss-dest_number-source_number-length_in_secs
+.It Fl p
+Use
+.Ar playcommand
+as the command string to execute for playing a voice message to some audio
+output facility. The characters
+.Em %s
+are replaced by the currently selected filename. The default string is
+.Dq Li cat %s \&| alaw2ulaw >/dev/audio .
+.It Fl t
+The value for
+.Ar timeout
+specifies the time in seconds the program rereads the spool directory
+when there is no keyboard activity.
+.El
+.Pp
+The screen output should be obvious. If in doubt, consult the source.

+.Sh DESCRIPTION
+.Nm
+is part of the isdn4bsd package and is used to configure the sound format
+conversion facilities of the /dev/i4btel interfaces.
+.Pp
+The following options are available:
+.Bl -tag -width Ds
+.It Fl c
+Clear the telephone input queue.
+.It Fl g
+Get the sound format currently in use.
+.It Fl u
+Set the /dev/i4btel unit number. The default value is zero to access
+device /dev/i4btel0.
+.It Fl A
+Do A-law (ISDN line) -> u-law (userland) conversion.
+.It Fl U
+Do u-law (ISDN line) -> A-law (userland) conversion.
+.It Fl N
+Set sound conversion to do no format conversion.
+.El
+.Pp
+The telephony data stream comes out of the line in a bit-reversed format,
+so the
+.Xr i4btel 4
+driver does the bit-reversion process in any case.
+.Pp
+Additionally, the user can specify to do A-law to u-law, u-law to A-law
+or no conversion at all in the i4btel driver by using the
+.Nm

+.Sh NAME
+.Nm isdntest
+.Nd isdn4bsd debugging and verification tool
+.Sh SYNOPSIS
+.Nm
+.Op Fl c Ar unit
+.Op Fl d Ar level
+.Op Fl i Ar number
+.Op Fl h
+.Op Fl o Ar number
+.Op Fl t Ar num
+.Op Fl w
+.Sh DESCRIPTION
+.Nm
+is part of the isdn4bsd package and may be used as a stimulation tool
+for debugging the isdn4bsd kernel functionality.
+.Pp
+NOTE:
+.Nm Isdntest
+must be run
+.Em instead
+of the
+.Xr isdnd 8
+daemon and cannot be used while the daemon runs.
+.Pp
+The following options are available:
+.Bl -tag -width Ds
+.It Fl c
+Use controller unit number for test.
+.It Fl d
+Set the debugging level
+.It Fl h
+Use HDLC as the B channel layer 1 protocol instead of no protocol.
+.It Fl i
+Use number to verify the incoming number.
+.It Fl o
+Use number as the outgoing number to dial.
+.It Fl t
+Set number of times the test pattern on the B-channel is exchanged
+.It Fl w
+Wait for keyboard input for terminating the call.
+.El
+.Pp
+The
+.Nm
+utility is currently of not much use for end users, it is primarily a debugging
+tool for development and is part of the release in the hope, that someone
+enhances it as a real self test and setup-verification tool!
+.Pp
+.Nm Isdntest
+does almost no error checking and error recovery, so unexpected
+hangs or crashes may occur.
+.Sh EXAMPLES
+For the following example, it is assumed that a machine with isdn4bsd
+installed is connected to an S0 bus and that one of the valid MSN's (MSN = Multiple Subscriber Number
+= telephone number) on this bus is
+.Em 42 .
+The
+.Xr isdnd 8
+.Em must
+not currently running on that machine! Executing:
+.Bd -literal -offset indent
+isdntest -i 42 -o 42
+.Ed
+.Pp
+will setup an outgoing call from that machine to itself, connect to itself
+and disconnect after 5 seconds.
+.Nm Isdntest
+has to be finished by the user by entering Control-C.

+The cable consists of a RJ-45 plug with both tx and rx connected and
+two jacks; the tx cables from the plug are wired to one jack and the
+rx cables from the plug are wired to the other jack.
+
+The computer must be equipped with two (!) supported passive cards and
+the cable from one card is plugged into one of the jacks while the cable
+to from the other card is plugged into the other jack.
+
+Now one card monitors the tx part of the S0 bus and the other card 
+monitors the rx part.

+.Op Fl f Ar filename
+.Op Fl h
+.Op Fl i
+.Op Fl l
+.Op Fl n Ar number
+.Op Fl o

+.Sh DESCRIPTION
+.Nm
+is part of the isdn4bsd package and is used to provide the user with a
+mnemonic display of the layers 1, 2 and 3 protocol activities on
+the D channel and hex dump of the B channel(s) activities.
+.Pp
+Together with two passive supported cards and an easy to build cable it can
+also be used to monitor the complete traffic on a S0 bus providing S0 bus
+analyzer features.
+.Pp
+The
+.Nm
+utility is only available for passive supported cards.
+.Pp
+.Em Note
+.Pp
+All filenames, user specified or default, get a date and time stamp string
+added in the form -yyyymmdd-hhmmss: a hyphen, four digits year, two digits
+month and day, a hyphen and two digits hour, minutes and seconds.
+Tracefiles no longer get overwritten.
+In case a new filename is needed within a second, the filename-generating
+mechanism sleeps one second.
+.Pp
+In case the program is sent a USR1 signal, a new user specified or default
+filename with a new date and timestamp is generated and opened.
+.Pp
+The following options can be used:
+.Bl -tag -width Ds
+.It Fl a
+Run
+.Nm
+in analyzer mode by using two passive cards and a custom cable which can
+be build as described in the file
+.Em cable.txt
+in the isdn4bsd source distribution. One card acts as a receiver for the
+transmitting direction on the S0 bus while the other card acts as a receiver
+for the receiving direction on the S0 bus. Complete traffic monitoring is
+possible using this setup.
+.It Fl b
+switch B channel tracing on (default off).
+.It Fl d
+switch D channel tracing off (default on).
+.It Fl f
+Use
+.Ar filename
+as the name of a file into which to write tracing output (default filename is
+isdntrace<n> where n is the number of the unit to trace).
+.It Fl h
+switch display of header off (default on).
+.It Fl i
+print layer 1 (I.430) INFO signals to monitor layer 1 activity (default off).
+.It Fl l
+switch displaying of Layer 2 (Q.921) frames off (default on).
+.It Fl n
+This option takes a numeric argument specifying the minimum
+frame size in octetts a frame must have to be displayed. (default 0)
+.It Fl o
+switch off writing trace output to a file (default on).
+.It Fl p
+Use
+.Ar filename
+as the name of a file used for the -B and -P options (default filename
+is isdntracebin<n> where n is the number of the unit to trace).
+.It Fl r
+Switch off printing a raw hexadecimal dump of the packets preceding
+the decoded protocol information (default on).

+Use
+.Ar number
+as the unit number of the controller card to trace (default 0).

+Switch on printing of packets with a non-Q.931 protocol discriminator.
+(default off).
+.It Fl B
+Write undecoded binary trace data to a file for later or remote
+analyzing (default off).
+.It Fl F
+This option can only be used when option -P (playback from binary data file)
+is used. The -F option causes playback not to stop at end of file but rather
+to wait for additional data to be available from the input file.
+.Pp
+This option is useful when trace data is accumulated in binary format (to
+save disk space) but a monitoring functionality is desired.
+(default off).
+.It Fl P
+Read undecoded binary trace data from file instead from device (default off).
+.It Fl R
+Use
+.Ar unit
+as the receiving interface unit number in analyze mode.
+.It Fl T
+Use
+.Ar unit
+as the transmitting interface unit number in analyze mode.

+.Pp
+When the USR1 signal is sent to a
+.Nm
+process, the currently used logfiles are reopened, so that logfile
+rotation becomes possible.
+.Pp
+The trace output should be obvious. It is very handy to have the following
+standard texts available when tracing ISDN protocols:
+.Pp
+.Bl -tag -width Ds -compact -offset indent
+.It Ar I.430
+ISDN BRI layer 1 protocol description.
+.It Ar Q.921
+ISDN D-channel layer 2 protocol description.
+.It Ar Q.931
+ISDN D-channel layer 3 protocol description.
+.It Ar 1TR6
+German-specific ISDN layer 3 protocol description. (NOTICE: decoding
+of the 1TR6 protocol is included but not supported since i dont have
+any longer access to a 1TR6 based ISDN installation.)
+.El
+.Pp
+.Nm Isdntrace
+automatically detects the layer 3 protocol being used by looking at the
+Protocol Discriminator (see: Q.931/1993 pp. 53).
+.Sh FILES
+.Bl -tag -width daddeldi -compact
+.It Pa /dev/i4btrc<n>
+The devicefile(s) used to get the trace messages for ISDN card unit <n>
+out of the kernel.
+.El
+.Sh EXAMPLES
+The command:
+.Bd -literal -offset indent
+isdntrace -f /var/tmp/isdn.trace
+.Ed
+.Pp
+will start D channel tracing on passive controller 0 with all except B
+channel tracing enabled and logs everything into the output file
+/var/tmp/isdn.trace-yyyymmdd-hhmmss (where yyyymmdd and hhmmss are replaced
+by the current date and time values).

+device driver is used by the
+.Xr isdnd 8
+daemon to exchange messages with the isdn4bsd kernel part for the purpose
+of call establishment, control and disconnection and to access various
+control and status informations.
+.Pp
+The messages and message parameters are documented in the include
+file
+.Em /usr/include/machine/i4b_ioctl.h .
+.Pp
+The available ioctl's are:
+.Pp
+.Bl -tag -width Ds -compact -offset indent
+.It Ar I4B_CDID_REQ
+Request a unique Call Description IDentifier (cdid) which identifies
+uniquely a single interaction of the local D channel with the exchange.
+.It Ar I4B_CONNECT_REQ
+Actively request a call setup to a remote ISDN subscriber.
+.It Ar I4B_CONNECT_RESP
+Respond to an incoming call, either accept, reject or ignore it.
+.It Ar I4B_DISCONNECT_REQ
+Actively terminate a connection.
+.It Ar I4B_CTRL_INFO_REQ
+Request information about an installed ISDN controller card.
+.It Ar I4B_DIALOUT_RESP
+Give information about call setup to driver who requested dialing out.
+.It Ar I4B_TIMEOUT_UPD
+Update the kernels timeout value(s) in case of dynamically calculated
+shorthold mode timing changes.
+.It Ar I4B_UPDOWN_IND
+Inform the kernel userland drivers about interface soft up/down status
+changes.
+.It Ar I4B_CTRL_DOWNLOAD
+Download firmware to active card(s).
+.It Ar I4B_ACTIVE_DIAGNOSTIC
+Return diagnostic information from active cards.

+.Pp
+Status and event messages available from the kernel are:
+.Pp
+.Bl -tag -width Ds -compact -offset indent
+.It Ar MSG_CONNECT_IND
+An incoming call from a remote ISDN user is indicated.
+.It Ar MSG_CONNECT_ACTIVE_IND
+After an incoming call has been accepted locally or an outgoing call has
+been accepted by a remote, the exchange signaled an active connection
+and the corresponding B-channel is switched through.
+.It Ar MSG_DISCONNECT_IND
+A call was terminated.
+.It Ar MSG_DIALOUT_IND
+A userland interface driver requests the daemon to dial out (typically a
+network interface when a packet arrives in its send queue).
+.It Ar MSG_IDLE_TIMEOUT_IND
+A call was terminated by the isdn4bsd kernel driver because a B-channel
+idle timeout occurred.
+.It Ar MSG_ACCT_IND
+Accounting information from a network driver.
+.It Ar MSG_CHARGING_IND
+Charging information from the kernel.

+.Sh DESCRIPTION
+The
+.Nm
+driver interfaces the IP subsystem of the operating system with the
+isdn4bsd package so that a transport of IP packets over an ISDN link
+is possible.
+.Pp
+The driver is just a glue layer between Serge Vakulenko's sppp
+backend and the ISDN4BSD package.
+.Pp
+Beginning with i4b version 0.95 (and only for
+.Fx ) ,
+the sppp
+subsystem was integrated into the
+.Nm
+driver to support more i4b/ISDN specific options. As a consequence it is no
+longer necessary to add a "options sppp" to your kernel
+.Xr config 8
+file. For configuration of the i4bsppp driver, either the
+.Xr ispppcontrol 8
+utility is used or it is configured via
+.Xr isdnd 1
+and its associated
+.Xr isdnd.rc 5
+file.
+.Pp
+In case an IP packet for a remote side arrives in the driver and no
+connection is established yet, the driver communicates with the
+.Xr isdnd 8
+daemon to establish a connection.
+.Pp
+The driver has support for interfacing to the
+.Xr bpf 4
+subsystem for using
+.Xr tcpdump 1
+with the
+.Nm isp
+interfaces.
+.Pp
+The
+.Xr ispppcontrol 8
+utility is used to configure all aspects of PPP required to connect to a
+remote site.
+.Sh LINK0 and LINK1
+The
+.Em link0
+and
+.Em link1
+flags given as parameters to
+.Xr ifconfig 8
+have the following meaning for the
+.Nm isp
+devices:
+.Bl -tag -width link0 -compact
+.Pp
+.It Li link0
+wait passively for connection
+.Pp
+.It Li link1
+auto-dial on output
+.El
+.Pp
+The
+.Em link0
+and

+.Nm i4btel
+.Nd isdn4bsd ISDN B-channel telephony interface driver
+.Sh FreeBSD SYNOPSIS
+.Cd pseudo-device \&"i4btel\&" Op count
+.Sh NetBSD SYNOPSIS
+none
+.Sh DESCRIPTION
+The
+.Nm
+driver provides an interface to the B-channel for telephony applications
+and is currently used by the
+.Xr isdnd 8
+for answering machine support. The driver is part of the isdn4bsd package.
+.Pp
+The lower six bits of the drivers's minor number is used to specify a
+unit number, wheras the upper two bits specify a functionality.
+.Pp
+Functionality zero is the usual telephony data stream i/o driver.
+.Pp
+Functionality one is used to enable commands to dial out and hang up and
+receive responses about the state of the dial out progress and status.
+This commands may change in the future, for details see the file
+.Em i4b_tel_ioctl.h
+and the
+.Xr isdnphone 1
+utility.
+.Pp
+The telephony data stream comes out of the line in a bit-reversed format,
+so the
+.Nm
+driver does the bit-reversion process in any case.
+.Pp
+Additionally, the user can specify to do A-law to u-law, u-law to A-law
+or no conversion at all in the i4btel driver by using the
+.Xr isdntelctl 8
+utility.
+.Pp
+The driver is able to process several ioctl's:
+.Pp
+.Bl -tag -width Ds -compact -offset indent
+.It Ar I4B_TEL_GETAUDIOFMT
+get currently used audio format conversion.
+.It Ar I4B_TEL_SETAUDIOFMT
+set currently used audio format conversion.
+.It Ar I4B_TEL_EMPTYINPUTQUEUE
+clear the input queue.
+.El
+.Pp
+For the I4B_TEL_GETAUDIOFMT and I4B_TEL_SETAUDIOFMT, the following
+parameters are available:
+.Pp
+.Bl -tag -width Ds -compact -offset indent
+.It Ar CVT_NONE
+do no A-law/u-law audio format conversion. The conversion path looks like
+this:
+.Pp
+USER <--> bitreversing <--> ISDN-line
+.Pp
+.It Ar CVT_ALAW2ULAW
+set set audio format conversion to do an audio conversion from A-law
+(on the ISDN line) to u-law (in the userland).
+The
+.Xr read 2
+conversion path looks like this:
+.Pp
+USER <-- u-law/A-law <-- bitreversing <-- ISDN-line
+.Pp
+and the
+.Xr write 2
+conversion path looks like this:
+.Pp
+USER --> u-law/A-law --> bitreversing --> ISDN-line
+.Pp
+.It Ar CVT_ULAW2ALAW
+set set audio format conversion to do an audio conversion from u-law
+(on the ISDN line) to A-law (in the userland).
+The
+.Xr read 2
+conversion path looks like this:
+.Pp
+USER <-- A-law/u-law <-- bitreversing <-- ISDN-line
+.Pp
+and the
+.Xr write 2
+conversion path looks like this:
+.Pp
+USER --> A-law/u-law --> bitreversing --> ISDN-line
+.Pp
+.El
+.Sh STANDARDS
+A-Law and u-Law are specified in ITU Recommendation G.711.

+.Sh DESCRIPTION
+The
+.Nm
+driver provides D-channel layer 1 supports as specified in ITU Recommendation
+I.430 and layer 1 support for the B-channel.
+.Pp
+The driver supports several 8 and 16bit passive ISDN cards from various
+manufacturers which are all based upon the popular Siemens ISDN chipset
+consisting of the ISDN Subscriber Access Controller ISAC (such as the
+PEB2085 or PSB 2186) and the High-Level Serial Communications Controller
+Extended HSCX (such as the SAB82525 or PSB21525). The newer IPAC chip
+(which integrates an ISAC and a HSCX in one chip, with the added benefit
+of larger FIFO buffers) is also supported.

+.Pp
+Notice that this cards must not have a
+.Em port
+value in the config line.
+.Pp
+Valid interrupts are 2, 3, 4, 5, 6 and 7.
+.Pp
+The i/o ports are memory mapped and the memory start address may
+be in the range 0xA0000 to 0xDF000 and uses 4kB of memory.
+.Pp
+.It Ar Teles S0/16, Creatix ISDN-S0, Dr. Neuhaus Niccy 1016
+.Pp
+The required (optional under
+.Nx )
+.Em flag
+value is 2.
+.Pp
+These boards have a jumper which specifies an i/o base address of either
+0xd80, 0xe80 or 0xf80. The remaining necessary configuration values are then
+programmed at run time by accessing this i/o port.
+.Pp
+Valid interrupts are 2, 3, 4, 5, 10, 11, 12 or 15.
+.Pp
+Valid memory start
+addresses are 0xC0000, 0xC2000, 0xC4000, 0xC6000, 0xC8000, 0xCA000, 0xCC000,
+0xCE000, 0xD0000, 0xD2000, 0xD4000, 0xD6000, 0xD8000, 0xDA000, 0xDC000 and
+0xDE000.
+.Pp
+Notice: Although the Jumpers are labeled 0xd80, 0xe80 or 0xf80, they
+also require i/o space at addresses 0x180, 0x280 or 0x380.
+.Pp
+.It Ar Teles S0/16.3
+.Pp
+The required (optional under
+.Nx )

+statement in the config line.
+.Pp
+Valid interrupts are 2, 5, 9, 10, 12 or 15.
+.Pp
+Notice: Although the switch positions are labeled 0x180, 0x280 and 0x380,
+the card is to be configured at 0xd80, 0xe80 or 0xf80 respectively!
+.Pp
+.It Ar AVM A1, AVM Fritz!Card
+.Pp
+The required (optional under
+.Nx )
+.Em flag
+value is 4.
+.Pp
+These boards have a jumper which specifies an i/o base address of either
+0x200, 0x240, 0x300 or 0x340.
+.Pp
+Valid interrupt configurations are 3, 4, 5, 6, 7, 10, 11, 12 or 15.
+.Pp
+Older Versions of the AVM A1 also require setting of an IRQ jumper, newer
+versions of this and the Fritz!Card only have an i/o base jumper and the
+interrupt is setup at runtime by reprogramming a register.
+.Pp
+This card is completely i/o mapped and must not have an

+.Pp
+Valid interrupt configurations are 5, 7, 10, 11, 12, 14, 15.
+.Pp
+Notice: this card has a strange address decoding scheme resulting in 64
+windows of some bytes length. Anyway, support for this card is good because
+the manufacturer gave out technical docs for this card!
+.Pp
+.Pp
+.It Ar "Dr. Neuhaus Niccy Go@"
+.Pp
+Valid i/o port values must be in the range 0x200 ... 0x3e0.
+.Pp
+Valid interrupt configurations are 3, 4, 5, 9, 10, 11, 12, 15.
+.Pp

+The card is auto-configured by the PnP kernel subsystem.
+.Pp
+.It Ar "ELSA QuickStep 1000pro (ISA)"
+.Pp
+I/O port in the range 0x160 ... 0x360 (occupies 8 bytes).

+.Pp
+The card is auto-configured by the PnP kernel subsystem.
+.Pp

+.Pp
+The required (optional under

+.Pp
+Valid interrupt configurations are (<unknown>).
+.Pp
+.It Ar "BSC ISDN Master"
+.It Ar "ITH ISDN MasterII"
+.It Ar "VMC ISDN Blaster"
+.Pp
+The card addresses are auto-configured by the Zorro bus kernel subsystem.
+The ISDN functions of the boards are at known (to the driver) relative
+addresses.
+.Pp
+Note that currently, you have to jumper the card interupt for
+.Em IPL 2
+instead of IPL 6 (which is used by most AmigaOS software).
+.Pp
+Note that the ITH ISDN MasterII doesn't work in the DraCo Zorro bus. This
+is no
+.Nx
+problem, but general.
+.El
+.Sh CAVEATS
+Note that all of the boards with I/O ports actually use several ranges
+of port addresses; Teles happen to refer to the 0xd80 range in their
+documentation (the board also uses 0x180 etc.), while AVM happen to refer
+to the 0x200 range in their documentation (the board also uses 0x600 etc.)
+The driver matches the manufacturers' description for the purposes of
+configuration, but of course makes use of all the ports in order to
+operate the card.
+.Sh BUGS
+Since there is no hardware documentation available from several manufacturers
+for their boards, it is likely that there are many, many bugs left.

+.Nm
+.Op Fl d
+.Op Fl l

+.Op Fl W
+.Op Fl c Ar maximum
+.Op Fl C Ar rate
+.Op Fl a Ar address | hostname
+.Op Fl p Ar filename
+.Op Fl R Ar rate
+.Op Ar configuration file
+.Sh DESCRIPTION
+The
+.Nm
+program
+should be run at boot time by
+.Pa /etc/rc
+(see
+.Xr rc 8 ) .
+It then listens for connections on certain
+internet sockets.  When a connection is found on one
+of its sockets, it decides what service the socket
+corresponds to, and invokes a program to service the request.
+The server program is invoked with the service socket
+as its standard input, output and error descriptors.
+After the program is
+finished,
+.Nm
+continues to listen on the socket (except in some cases which
+will be described below).  Essentially,
+.Nm
+allows running one daemon to invoke several others,
+reducing load on the system.
+.Pp
+The following options are available:
+.Bl -tag -width indent
+.It Fl d
+Turn on debugging.
+.It Fl l
+Turn on logging of successful connections.
+.It Fl w
+Turn on TCP Wrapping for external services.
+See the
+.Sx "IMPLEMENTATION NOTES"
+section for more information on TCP Wrappers support.
+.It Fl W
+Turn on TCP Wrapping for internal services which are built in to
+.Nm .
+.It Fl c Ar maximum
+Specify the default maximum number of
+simultaneous invocations of each service;
+the default is unlimited.
+May be overridden on a per-service basis with the "max-child"
+parameter.
+.It Fl C Ar rate
+Specify the default maximum number of times a service can be invoked
+from a single IP address in one minute; the default is unlimited.
+May be overridden on a per-service basis with the
+"max-connections-per-ip-per-minute" parameter.
+.It Fl R Ar rate
+Specify the maximum number of times a service can be invoked
+in one minute; the default is 256.
+A rate of 0 allows an unlimited number of invocations.
+.It Fl a
+Specify one specific IP address to bind to.
+Alternatively, a hostname can be specified,
+in which case the IPv4 or IPv6 address
+which corresponds to that hostname is used.
+Usually a hostname is specified when
+.Nm
+is run inside a
+.Xr jail 8 ,
+in which case the hostname corresponds to the
+.Xr jail 8
+environment.
+.Pp
+When hostname specification is used
+and both IPv4 and IPv6 bindings are desired,
+one entry with the appropriate
+.Em protocol
+type for each binding
+is required for each service in
+.Pa /etc/inetd.conf .
+For example,
+a TCP-based service would need two entries,
+one using
+.Dq tcp4
+for the
+.Em protocol
+and the other using
+.Dq tcp6 .
+See the explanation of the
+.Pa /etc/inetd.conf
+.Em protocol
+field below.
+.It Fl p
+Specify an alternate file in which to store the process ID.
+.El
+.Pp
+Upon execution,
+.Nm
+reads its configuration information from a configuration
+file which, by default, is
+.Pa /etc/inetd.conf .
+There must be an entry for each field of the configuration
+file, with entries for each field separated by a tab or
+a space.  Comments are denoted by a
+.Dq #
+at the beginning
+of a line.  There must be an entry for each field.  The
+fields of the configuration file are as follows:
+.Pp
+.Bd -unfilled -offset indent -compact
+service name
+socket type
+protocol
+{wait|nowait}[/max-child[/max-connections-per-ip-per-minute]]
+user[:group][/login-class]
+server program
+server program arguments
+.Ed
+.Pp
+To specify an
+.Tn "ONC RPC" Ns -based
+service, the entry would contain these fields:
+.Pp
+.Bd -unfilled -offset indent -compact
+service name/version
+socket type
+rpc/protocol
+user[:group][/login-class]
+server program
+server program arguments
+.Ed
+.Pp
+There are two types of services that
+.Nm
+can start: standard and TCPMUX.
+A standard service has a well-known port assigned to it;
+it may be a service that implements an official Internet standard or is a
+.Bx Ns -specific
+service.
+As described in
+.Tn RFC 1078 ,
+TCPMUX services are nonstandard services that do not have a
+well-known port assigned to them.
+They are invoked from
+.Nm
+when a program connects to the
+.Dq tcpmux
+well-known port and specifies
+the service name.
+This feature is useful for adding locally-developed servers.
+TCPMUX requests are only accepted when the multiplexor service itself
+is enabled, above and beyond and specific TCPMUX-based servers; see the
+discussion of internal services below.
+.Pp
+The
+.Em service-name
+entry is the name of a valid service in
+the file
+.Pa /etc/services ,
+or the specification of a
+.Ux
+domain socket (see below).
+For
+.Dq internal
+services (discussed below), the service
+name
+should
+be the official name of the service (that is, the first entry in
+.Pa /etc/services ) .
+When used to specify an
+.Tn "ONC RPC" Ns -based
+service, this field is a valid RPC service name in
+the file
+.Pa /etc/rpc .
+The part on the right of the
+.Dq /
+is the RPC version number.
+This
+can simply be a single numeric argument or a range of versions.
+A range is bounded by the low version to the high version -
+.Dq rusers/1-3 .
+For TCPMUX services, the value of the
+.Em service-name
+field consists of the string
+.Dq tcpmux
+followed by a slash and the
+locally-chosen service name.
+The service names listed in
+.Pa /etc/services
+and the name
+.Dq help
+are reserved.
+Try to choose unique names for your TCPMUX services by prefixing them with
+your organization's name and suffixing them with a version number.
+.Pp
+The
+.Em socket-type
+should be one of
+.Dq stream ,
+.Dq dgram ,
+.Dq raw ,
+.Dq rdm ,
+or
+.Dq seqpacket ,
+depending on whether the socket is a stream, datagram, raw,
+reliably delivered message, or sequenced packet socket.
+TCPMUX services must use
+.Dq stream .
+.Pp
+The
+.Em protocol
+must be a valid protocol or
+.Dq unix .
+Examples are
+.Dq tcp
+or
+.Dq udp ,
+both of which imply IPv4 for backward compatibility.
+The names
+.Dq tcp4
+and
+.Dq udp4
+specify IPv4 only.
+The names
+.Dq tcp6
+and
+.Dq udp6
+specify IPv6 only.
+The names
+.Dq tcp46
+and
+.Dq udp46
+specify that the entry accepts both IPv4 and IPv6 connections
+via a wildcard
+.Dv AF_INET6
+socket.
+If it is desired that the service is reachable via T/TCP, one should
+specify
+.Dq tcp/ttcp ,
+which implies IPv4 for backward compatibility.
+The name
+.Dq tcp4/ttcp
+specifies IPv4 only, while
+.Dq tcp6/ttcp
+specifies IPv6 only.
+The name
+.Dq tcp46/ttcp
+specify that the entry accepts both IPv6 and IPv6 connections
+via a wildcard
+.Dv AF_INET6
+socket.
+Rpc based services
+(for which only IPv4 is supported at this time)
+are specified with the
+.Dq rpc/tcp
+or
+.Dq rpc/udp
+service type.
+TCPMUX services must use
+.Dq tcp ,
+.Dq tcp4 ,
+.Dq tcp6
+or
+.Dq tcp46 .
+.Pp
+The
+.Em wait/nowait
+entry specifies whether the server that is invoked by
+.Nm
+will take over
+the socket associated with the service access point, and thus whether
+.Nm
+should wait for the server to exit before listening for new service
+requests.
+Datagram servers must use
+.Dq wait ,
+as they are always invoked with the original datagram socket bound
+to the specified service address.
+These servers must read at least one datagram from the socket
+before exiting.
+If a datagram server connects
+to its peer, freeing the socket so
+.Nm
+can receive further messages on the socket, it is said to be
+a
+.Dq multi-threaded
+server;
+it should read one datagram from the socket and create a new socket
+connected to the peer.
+It should fork, and the parent should then exit
+to allow
+.Nm
+to check for new service requests to spawn new servers.
+Datagram servers which process all incoming datagrams
+on a socket and eventually time out are said to be
+.Dq single-threaded .
+.Xr Comsat 8 ,
+.Pq Xr biff 1
+and
+.Xr talkd 8
+are both examples of the latter type of
+datagram server.
+.Xr Tftpd 8
+is an example of a multi-threaded datagram server.
+.Pp
+Servers using stream sockets generally are multi-threaded and
+use the
+.Dq nowait
+entry.
+Connection requests for these services are accepted by
+.Nm ,
+and the server is given only the newly-accepted socket connected
+to a client of the service.
+Most stream-based services operate in this manner.
+Stream-based servers that use
+.Dq wait
+are started with the listening service socket, and must accept
+at least one connection request before exiting.
+Such a server would normally accept and process incoming connection
+requests until a timeout.
+TCPMUX services must use
+.Dq nowait .
+.Pp
+The maximum number of outstanding child processes (or
+.Dq threads )
+for a
+.Dq nowait
+service may be explicitly specified by appending a
+.Dq /
+followed by the number to the
+.Dq nowait
+keyword.
+Normally
+(or if a value of zero is specified) there is no maximum.
+Otherwise,
+once the maximum is reached, further connection attempts will be
+queued up until an existing child process exits.
+This also works
+in the case of
+.Dq wait
+mode, although a value other than one (the
+default) might not make sense in some cases.
+You can also specify the maximum number of connections per minute
+for a given IP address by appending
+a
+.Dq /
+followed by the number to the maximum number of
+outstanding child processes.
+Once the maximum is reached, further
+connections from this IP address will be dropped until the end of the
+minute.
+.Pp
+The
+.Em user
+entry should contain the user name of the user as whom the server
+should run.  This allows for servers to be given less permission
+than root.
+Optional
+.Em group
+part separated by
+.Dq \&:
+allows to specify group name different
+than default group for this user.
+Optional
+.Em login-class
+part separated by
+.Dq /
+allows to specify login class different
+than default
+.Dq daemon
+login class.
+.Pp
+The
+.Em server-program
+entry should contain the pathname of the program which is to be
+executed by
+.Nm
+when a request is found on its socket.  If
+.Nm
+provides this service internally, this entry should
+be
+.Dq internal .
+.Pp
+The
+.Em server program arguments
+should be just as arguments
+normally are, starting with argv[0], which is the name of
+the program.  If the service is provided internally, the
+.Em service-name
+of the service (and any arguments to it) or the word
+.Dq internal
+should take the place of this entry.
+.Pp
+Currently, the only internal service to take arguments is
+.Dq auth .
+Without options, the service will always return
+.Dq ERROR\ : HIDDEN-USER .
+The available arguments to this service that alter its behavior are:
+.Bl -tag -width indent
+.It Fl d Ar fallback
+Provide a
+.Ar fallback
+username.
+If the real
+.Dq auth
+service is enabled
+(with the
+.Fl r
+option discussed below),
+return this username instead of an error
+when lookups fail
+for either socket credentials or the username.
+If the real
+.Dq auth
+service is disabled,
+return this username for every request.
+This is primarily useful when running this service on a NAT machine.
+.It Fl g
+Instead of returning
+the user's name to the ident requester,
+report a
+username made up of random alphanumeric characters,
+e.g.\&
+.Dq c0c993 .
+The
+.Fl g
+flag overrides not only the user names,
+but also any fallback name,
+.Pa .fakeid
+or
+.Pa .noident
+files.
+.It Fl t Xo
+.Ar sec Ns Op . Ns Ar usec
+.Xc
+Specify a timeout for the service.
+The default timeout is 10.0 seconds.
+.It Fl r
+Offer a real
+.Dq auth
+service, as per RFC 1413.
+All the remaining flags apply only in this case.
+.It Fl i
+Return numeric user IDs instead of usernames.
+.It Fl f
+If the file
+.Pa .fakeid
+exists in the home directory of the identified user, report the username
+found in that file instead of the real username.
+If the username found in
+.Pa .fakeid
+is that of an existing user,
+then the real username is reported.
+If the
+.Fl i
+flag is also given then the username in
+.Pa .fakeid
+is checked against existing user IDs instead.
+.It Fl F
+same as
+.Fl f
+but without the restriction that the username in
+.Pa .fakeid
+must not match an existing user.
+.It Fl n
+If the file
+.Pa .noident
+exists in the home directory of the identified user, return
+.Dq ERROR\ : HIDDEN-USER .
+This overrides any
+.Pa fakeid
+file which might exist.
+.It Fl o Ar osname
+Use
+.Ar osname
+instead of the name of the system as reported by
+.Xr uname 3 .
+.El
+.Pp
+The
+.Nm
+program
+also provides several other
+.Dq trivial
+services internally by use of
+routines within itself.  These services are
+.Dq echo ,
+.Dq discard ,
+.Dq chargen
+(character generator),
+.Dq daytime
+(human readable time), and
+.Dq time
+(machine readable time, in the form of the number of seconds since
+midnight, January 1, 1900).  All of these services are available in
+both TCP and UDP versions; the UDP versions will refuse service if the
+request specifies a reply port corresponding to any internal service.
+(This is done as a defense against looping attacks; the remote IP address
+is logged.)
+For details of these services, consult the
+appropriate
+.Tn RFC
+document.
+.Pp
+The TCPMUX-demultiplexing service is also implemented as an internal service.
+For any TCPMUX-based service to function, the following line must be included
+in
+.Pa inetd.conf :
+.Bd -literal -offset indent
+tcpmux	stream	tcp	nowait	root	internal
+.Ed
+.Pp
+When given the
+.Fl l
+option
+.Nm
+will log an entry to syslog each time a connection is accepted, noting the
+service selected and the IP-number of the remote requester if available.
+Unless otherwise specified in the configuration file,
+and in the absence of the
+.Fl W
+and
+.Fl w
+options,
+.Nm
+will log to the
+.Dq daemon
+facility.
+.Pp
+The
+.Nm
+program
+rereads its configuration file when it receives a hangup signal,
+.Dv SIGHUP .
+Services may be added, deleted or modified when the configuration file
+is reread.
+Except when started in debugging mode,
+.Nm
+records its process ID in the file
+.Pa /var/run/inetd.pid
+to assist in reconfiguration.
+.Sh IMPLEMENTATION NOTES
+.Ss TCP Wrappers
+When given the
+.Fl w
+option,
+.Nm
+will wrap all services specified as
+.Dq stream nowait
+or
+.Dq dgram
+except for
+.Dq internal
+services.
+If the
+.Fl W
+option is given, such
+.Dq internal
+services will be wrapped.
+If both options are given, wrapping for both
+internal and external services will be enabled.
+Either wrapping option
+will cause failed connections to be logged to the
+.Dq auth
+syslog facility.
+Adding the
+.Fl l
+flag to the wrapping options will include successful connections in the
+logging to the
+.Dq auth
+facility.
+.Pp
+Note that
+.Nm
+only wraps requests for a
+.Dq wait
+service while no servers are available to service requests.
+Once a
+connection to such a service has been allowed,
+.Nm
+has no control
+over subsequent connections to the service until no more servers
+are left listening for connection requests.
+.Pp
+When wrapping is enabled, the
+.Pa tcpd
+daemon is not required, as that functionality is builtin.
+For more information on TCP Wrappers, see the relevant documentation
+.Pq Xr hosts_access 5 .
+When reading that document, keep in mind that
+.Dq internal
+services have no associated daemon name.
+Therefore, the service name
+as specified in
+.Pa inetd.conf
+should be used as the daemon name for
+.Dq internal
+services.
+.Ss TCPMUX
+.Tn RFC 1078
+describes the TCPMUX protocol:
+``A TCP client connects to a foreign host on TCP port 1.  It sends the
+service name followed by a carriage-return line-feed <CRLF>.  The
+service name is never case sensitive.  The server replies with a
+single character indicating positive (+) or negative (\-)
+acknowledgment, immediately followed by an optional message of
+explanation, terminated with a <CRLF>.  If the reply was positive,
+the selected protocol begins; otherwise the connection is closed.''
+The program is passed the TCP connection as file descriptors 0 and 1.
+.Pp
+If the TCPMUX service name begins with a
+.Dq + ,
+.Nm
+returns the positive reply for the program.
+This allows you to invoke programs that use stdin/stdout
+without putting any special server code in them.
+.Pp
+The special service name
+.Dq help
+causes
+.Nm
+to list TCPMUX services in
+.Pa inetd.conf .
+.Ss IPsec
+The implementation includes a tiny hack
+to support IPsec policy settings for each socket.
+A special form of comment line, starting with
+.Dq Li #@ ,
+is interpreted as a policy specifier.
+Everything after the
+.Dq Li #@
+will be used as an IPsec policy string,
+as described in
+.Xr ipsec_set_policy 3 .
+Each
+policy specifier is applied to all the following lines in
+.Pa inetd.conf
+until the next policy specifier.
+An empty policy specifier resets the IPsec policy.
+.Pp
+If an invalid IPsec policy specifier appears in
+.Pa inetd.conf ,
+.Nm
+will provide an error message via the
+.Xr syslog 3
+interface and abort execution.
+.Ss Ux Domain Sockets
+In addition to running services on IP sockets,
+.Nm
+can also manage
+.Ux
+domain sockets.
+To do this you specify a
+.Em protocol
+of
+.Dq unix
+and specify the
+.Ux
+domain socket as the
+.Em service-name .
+The
+.Em service-type
+may be
+.Dq stream
+or
+.Dq dgram .
+The specification of the socket must be
+an absolute path name,
+optionally prefixed by an owner and mode
+of the form
+.Em :user:group:mode: .
+The specification:
+.Pp
+.Dl ":news:daemon:220:/var/run/sock"
+.Pp
+creates a socket owned
+by user
+.Dq news
+in group
+.Dq daemon
+with permissions allowing only that user and group to connect.
+The default owner is the user that
+.Nm
+is running as.
+The default mode only allows the socket's owner to connect.
+.Pp
+.Sy WARNING :
+while creating
+.Ux
+domain socket,
+.Nm
+must change the ownership and permissions on the socket.
+This can only be done securely if
+the directory in which the socket is created
+is writable only by root.
+Do
+.Em NOT
+use
+.Nm
+to create sockets in world writable directories,
+such as
+.Pa /tmp ,
+instead use
+.Pa /var/run
+or a similar directory.
+.Pp
+Internal services may be run on
+.Ux
+domain sockets, in the usual way.
+In this case
+the name of the internal service
+is determined using
+the last component of the socket's pathname.

+/*
+ * Inetd - Internet super-server
+ *
+ * This program invokes all internet services as needed.  Connection-oriented
+ * services are invoked each time a connection is made, by creating a process.
+ * This process is passed the connection as file descriptor 0 and is expected
+ * to do a getpeername to find out the source host and port.
+ *
+ * Datagram oriented services are invoked when a datagram
+ * arrives; a process is created and passed a pending message
+ * on file descriptor 0.  Datagram servers may either connect
+ * to their peer, freeing up the original socket for inetd
+ * to receive further messages on, or ``take over the socket'',
+ * processing all arriving datagrams and, eventually, timing
+ * out.	 The first type of server is said to be ``multi-threaded'';
+ * the second type of server ``single-threaded''.
+ *
+ * Inetd uses a configuration file which is read at startup
+ * and, possibly, at some later time in response to a hangup signal.
+ * The configuration file is ``free format'' with fields given in the
+ * order shown below.  Continuation lines for an entry must begin with
+ * a space or tab.  All fields must be present in each entry.
+ *
+ *	service name			must be in /etc/services
+ *					or name a tcpmux service 
+ *					or specify a unix domain socket
+ *	socket type			stream/dgram/raw/rdm/seqpacket
+ *	protocol			tcp[4][6][/faith,ttcp], udp[4][6], unix
+ *	wait/nowait			single-threaded/multi-threaded
+ *	user				user to run daemon as
+ *	server program			full path name
+ *	server program arguments	maximum of MAXARGS (20)
+ *
+ * TCP services without official port numbers are handled with the
+ * RFC1078-based tcpmux internal service. Tcpmux listens on port 1 for
+ * requests. When a connection is made from a foreign host, the service
+ * requested is passed to tcpmux, which looks it up in the servtab list
+ * and returns the proper entry for the service. Tcpmux returns a
+ * negative reply if the service doesn't exist, otherwise the invoked
+ * server is expected to return the positive reply if the service type in
+ * inetd.conf file has the prefix "tcpmux/". If the service type has the
+ * prefix "tcpmux/+", tcpmux will return the positive reply for the
+ * process; this is for compatibility with older server code, and also
+ * allows you to invoke programs that use stdin/stdout without putting any
+ * special server code in them. Services that use tcpmux are "nowait"
+ * because they do not have a well-known port and hence cannot listen
+ * for new requests.
+ *
+ * For RPC services
+ *	service name/version		must be in /etc/rpc
+ *	socket type			stream/dgram/raw/rdm/seqpacket
+ *	protocol			rpc/tcp, rpc/udp
+ *	wait/nowait			single-threaded/multi-threaded
+ *	user				user to run daemon as
+ *	server program			full path name
+ *	server program arguments	maximum of MAXARGS
+ *
+ * Comment lines are indicated by a `#' in column 1.
+ *
+ * #ifdef IPSEC
+ * Comment lines that start with "#@" denote IPsec policy string, as described
+ * in ipsec_set_policy(3).  This will affect all the following items in
+ * inetd.conf(8).  To reset the policy, just use "#@" line.  By default,
+ * there's no IPsec policy.

+.Sh DESCRIPTION
+.Nm Iostat
+displays kernel
+.Tn I/O
+statistics on terminal, device and cpu operations.
+The first statistics that are printed are averaged over the system uptime.
+To get information about the current activity, a suitable wait time should
+be specified, so that the subsequent sets of printed statistics will be
+averaged over that time.
+.Pp
+The options are as follows:
+.Bl -tag -width flag
+.It Fl c
+Repeat the display
+.Ar count
+times.
+If no
+.Ar wait
+interval is specified, the default is 1 second.
+.It Fl C
+Display CPU statistics.
+This is on by default, unless
+.Fl d
+is specified.
+.It Fl d
+Display only device statistics.
+If this flag is turned on, only device statistics will be displayed, unless
+.Fl C
+or
+.Fl T
+is also specfied to enable the display of CPU or TTY statistics.
+.It Fl h
+Put
+.Nm
+in
+.Sq top
+mode.
+In this mode,
+.Nm
+will show devices in order from highest to lowest bytes
+per measurement cycle.
+.It Fl I
+Display total statstics for a given time period, rather than average
+statistics for each second during that time period.
+.It Fl K
+In the blocks transfered display (-o), display block count in kilobytes rather
+then the device native block size.
+.It Fl M
+Extract values associated with the name list from the specified core
+instead of the default
+.Dq Pa /dev/kmem .
+.It Fl n
+Display up to
+.Ar devs
+number of devices.
+.Nm
+will display fewer devices if there aren't
+.Ar devs
+devices present.
+.It Fl N
+Extract the name list from the specified system instead of the default
+.Dq Pa /boot/kernel/kernel .
+.It Fl o
+Display old-style
+.Nm
+device statistics.
+Sectors per second, transfers per second, and miliseconds per seek are
+displayed.
+If
+.Fl I
+is specified, total blocks/sectors, total transfers, and
+miliseconds per seek are displayed.
+.It Fl t
+Specify which types of devices to display.
+There are three different categories of devices:
+.Pp
+.Bl -tag -width indent -compact
+.It device type:
+.Bl -tag -width 9n -compact
+.It da
+Direct Access devices
+.It sa
+Sequential Access devices
+.It printer

+.It other
+Any other device interface
+.El
+.Pp
+.It passthrough:
+.Bl -tag -width 9n -compact
+.It pass
+Passthrough devices
+.El
+.El
+.Pp
+The user must specify at least one device type, and may specify at most
+one device type from each category.
+Multiple device types in a single device type statement must be separated by
+commas.
+.Pp
+Any number of
+.Fl t
+arguments may be specified on the command line.
+All
+.Fl t
+arguments are ORed together to form a matching expression against which
+all devices in the system are compared.
+Any device that fully matches any
+.Fl t
+argument will be included in the
+.Nm
+output, up to the number of devices that can be displayed in
+80 columns, or the maximum number of devices specified by the user.
+.It Fl T
+Display TTY statistics.
+This is on by default, unless
+.Fl d
+is specified.
+.It Fl w
+Pause
+.Ar wait
+seconds between each display.
+If no repeat
+.Ar count
+is specified, the default is infinity.
+.It Fl ?\&
+Display a usage statement and exit.
+.El
+.Pp
+.Nm Iostat
+displays its information in the following format:
+.Bl -tag -width flag
+.It tty
+.Bl -tag -width indent -compact
+.It tin
+characters read from terminals
+.It tout
+characters written to terminals
+.El
+.It devices
+Device operations.
+The header of the field is the device name and unit number.
+.Nm
+will display as many devices as will fit in a standard 80 column screen, or
+the maximum number of devices in the system, whichever is smaller.
+If
+.Fl n
+is specified on the command line,
+.Nm
+will display the smaller of the
+requested number of devices, and the maximum number of devices in the system.
+To force
+.Nm
+to display specific drives, their names may be supplied on the command
+line.
+.Nm
+will not display more devices than will fit in an 80 column screen, unless
+the
+.Fl n
+argument is given on the command line to specify a maximum number of
+devices to display.
+If fewer devices are specified on the command line than will fit in an 80
+column screen,
+.Nm
+will show only the specified devices.
+.Pp
+The standard
+.Nm
+device display shows the following statistics:
+.Pp
+.Bl -tag -width indent -compact
+.It KB/t
+kilobytes per transfer
+.It tps
+transfers per second
+.It MB/s

+.Sh HISTORY
+This version of
+.Nm
+first appeared in
+.Fx 3.0 .
+.Sh BUGS
+The use of
+.Nm
+as a debugging tool for crash dumps is probably limited because there is
+currently no way to get statistics that only cover the time immediately before
+the crash.

+.Dt JAIL 8
+.Os
+.Sh NAME
+.Nm jail
+.Nd "imprison process and its descendants"
+.Sh SYNOPSIS
+.Nm
+.Ar path hostname ip-number command ...
+.Sh DESCRIPTION
+The
+.Nm
+command imprisons a process and all future descendants.
+.Pp
+Please see the
+.Xr jail 2
+man page for further details.
+.Sh EXAMPLES
+.Ss "Setting up a Jail Directory Tree"
+This example shows how to setup a jail directory tree
+containing an entire
+.Fx
+distribution:
+.Bd -literal
+D=/here/is/the/jail
+cd /usr/src
+mkdir -p $D
+make world DESTDIR=$D
+cd etc
+make distribution DESTDIR=$D -DNO_MAKEDEV_RUN
+cd $D/dev
+sh MAKEDEV jail
+cd $D
+ln -sf dev/null kernel
+.Ed
+.Pp
+In many cases this example would put far more stuff in the jail than is needed.
+In the other extreme case a jail might contain only one single file:
+the executable to be run in the jail.
+.Pp
+We recommend experimentation and caution that it is a lot easier to
+start with a
+.Dq fat
+jail and remove things until it stops working,
+than it is to start with a
+.Dq thin
+jail and add things until it works.
+.Ss "Setting Up a Jail"
+Do what was described in
+.Sx "Setting Up a Jail Directory Tree"
+to build the jail directory tree.
+For the sake of this example, we will
+assume you built it in
+.Pa /data/jail/192.168.11.100 ,
+named for the jailed IP address.
+Substitute below as needed with your
+own directory, IP address, and hostname.
+.Pp
+First, you will want to set up your real system's environment to be
+.Dq jail-friendly .
+For consistency, we will refer to the parent box as the
+.Dq "host environment" ,
+and to the jailed virtual machine as the
+.Dq "jail environment" .
+Because jail is implemented using IP aliases, one of the first things to do
+is to disable IP services on the host system that listen on all local
+IP addresses for a service.
+This means changing
+.Xr inetd 8
+to only listen on the
+appropriate IP address, and so forth.
+Add the following to
+.Pa /etc/rc.conf
+in the host environment:
+.Bd -literal -offset indent
+sendmail_enable="NO"
+inetd_flags="-wW -a 192.168.11.23"
+portmap_enable="NO"
+.Ed
+.Pp
+.Li 192.168.11.23
+is the native IP address for the host system, in this example.
+Daemons that run out of
+.Xr inetd 8
+can be easily set to use only the specified host IP address.
+Other daemons
+will need to be manually configured\(emfor some this is possible through
+the
+.Xr rc.conf 5
+flags entries, for others it is not possible without munging
+the per-application configuration files, or even recompiling.
+For those
+applications that cannot specify the IP they run on, it is better to disable
+them, if possible.
+.Pp
+A number of daemons ship with the base system that may have problems when
+run from outside of a jail in a jail-centric environment.
+This includes
+.Xr sendmail 8 ,
+.Xr named 8 ,
+and
+.Xr rpcbind 8 .
+While
+.Xr sendmail 8
+and
+.Xr named 8
+can be configured to listen only on a specific
+IP using their configuration files, in most cases it is easier to simply
+run the daemons in jails only, and not in the host environment.
+Attempting to serve
+NFS from the host environment may also cause confusion, and cannot be
+easily reconfigured to use only specific IPs, as some NFS services are
+hosted directly from the kernel.
+Any third party network software running
+in the host environment should also be checked and configured so that it
+does not bind all IP addresses, which would result in those services also
+appearing to be offered by the jail environments.
+.Pp
+Once
+these daemons have been disabled or fixed in the host environment, it is
+best to reboot so that all daemons are in a known state, to reduce the
+potential for confusion later (such as finding that when you send mail
+to a jail, and its sendmail is down, the mail is delivered to the host,
+etc.)
+.Pp
+Start any jails for the first time without configuring the network
+interface so that you can clean it up a little and set up accounts.
+As
+with any machine (virtual or not) you will need to set a root password, time
+zone, etc.
+Before beginning, you may want to copy
+.Xr sysinstall 8
+into the tree so that you can use it to set things up easily.
+Do this using:
+.Bd -literal -offset indent
+mkdir /data/jail/192.168.11.100/stand
+cp /stand/sysinstall /data/jail/192.168.11.100/stand
+.Ed
+.Pp
+Now start the jail:
+.Pp
+.Dl "jail /data/jail/192.168.11.100 testhostname 192.168.11.100 /bin/sh"
+.Pp
+You will end up with a shell prompt, assuming no errors, within the jail.
+You can now run
+.Pa /stand/sysinstall
+and do the post-install configuration to set various configuration options,
+or perform these actions manually by editing
+.Pa /etc/rc.conf ,
+etc.
+.Pp
+.Bl -bullet -offset indent -compact
+.It
+Create an empty
+.Pa /etc/fstab
+to quell startup warnings about missing fstab
+.It
+Disable the port mapper
+.Pa ( /etc/rc.conf :
+.Li portmap_enable="NO" )
+.It
+Run
+.Xr newaliases 1
+to quell
+.Xr sendmail 8
+warnings.
+.It
+Disable interface configuration to quell startup warnings about
+.Xr ifconfig 8
+.Pq Li network_interfaces=""
+.It
+Configure
+.Pa /etc/resolv.conf
+so that name resolution within the jail will work correctly
+.It
+Set a root password, probably different from the real host system
+.It
+Set the timezone
+.It
+Add accounts for users in the jail environment
+.It
+Install any packages that you think the environment requires
+.El
+.Pp
+You may also want to perform any package-specific configuration (web servers,
+SSH servers, etc), patch up
+.Pa /etc/syslog.conf
+so it logs as you would like, etc.
+.Pp
+Exit from the shell, and the jail will be shut down.
+.Ss "Starting the Jail"
+You are now ready to restart the jail and bring up the environment with
+all of its daemons and other programs.
+To do this, first bring up the
+virtual host interface, and then start the jail's
+.Pa /etc/rc
+script from within the jail.
+.Pp
+NOTE: If you plan to allow untrusted users to have root access inside the
+jail, you may wish to consider setting the
+.Va security.jail.set_hostname_allowed
+to 0.
+Please see the management reasons why this is a good idea.
+If you do decide to set this variable,
+it must be set before starting any jails, and once each boot.
+.Bd -literal -offset indent
+ifconfig ed0 inet alias 192.168.11.100/32
+mount -t procfs proc /data/jail/192.168.11.100/proc
+jail /data/jail/192.168.11.100 testhostname 192.168.11.100 \\
+	/bin/sh /etc/rc
+.Ed
+.Pp
+A few warnings will be produced, because most
+.Xr sysctl 8
+configuration variables cannot be set from within the jail, as they are
+global across all jails and the host environment.
+However, it should all
+work properly.
+You should be able to see
+.Xr inetd 8 ,
+.Xr syslogd 8 ,
+and other processes running within the jail using
+.Xr ps 1 ,
+with the
+.Ql J
+flag appearing beside jailed processes.
+You should also be able to
+.Xr telnet 1
+to the hostname or IP address of the jailed environment, and log
+in using the accounts you created previously.
+.Ss "Managing the Jail"
+Normal machine shutdown commands, such as
+.Xr halt 8 ,
+.Xr reboot 8 ,
+and
+.Xr shutdown 8 ,
+cannot be used successfully within the jail.
+To kill all processes in a
+jail, you may log into the jail and, as root, use one of the following
+commands, depending on what you want to accomplish:
+.Pp
+.Bd -literal -offset indent
+kill -TERM -1
+kill -KILL -1
+.Ed
+.Pp
+This will send the
+.Dv SIGTERM
+or
+.Dv SIGKILL
+signals to all processes in the jail from within the jail.
+Depending on
+the intended use of the jail, you may also want to run
+.Pa /etc/rc.shutdown
+from within the jail.
+Currently there is no way to insert new processes
+into a jail, so you must first log into the jail before performing these
+actions.
+.Pp
+To kill processes from outside the jail, you must individually identify the
+PID of each process to be killed.
+The
+.Pa /proc/ Ns Ar pid Ns Pa /status
+file contains, as its last field, the hostname of the jail in which the
+process runs, or
+.Dq Li -
+to indicate that the process is not running within a jail.
+The
+.Xr ps 1
+command also shows a
+.Ql J
+flag for processes in a jail.
+However, the hostname for a jail may be, by
+default, modified from within the jail, so the
+.Pa /proc
+status entry is unreliable by default.
+To disable the setting of the hostname
+from within a jail, set the
+.Va security.jail.set_hostname_allowed
+sysctl variable in the host environment to 0, which will affect all jails.
+You can have this sysctl set on each boot using
+.Xr sysctl.conf 5 .
+Just add the following line to
+.Pa /etc/sysctl.conf :
+.Pp
+.Dl security.jail.set_hostname_allowed=0
+.Pp
+In a future version of
+.Fx ,
+the mechanisms for managing jails will be
+more refined.
+.Ss "Sysctl MIB Entries"
+Certain aspects of the jail containments environment may be modified from
+the host environment using
+.Xr sysctl 8
+MIB variables.
+Currently, these variables affect all jails on the system, although in
+the future this functionality may be finer grained.
+.Bl -tag -width XXX
+.It Va security.jail.set_hostname_allowed
+This MIB entry determines whether or not processes within a jail are
+allowed to change their hostname via
+.Xr hostname 1
+or
+.Xr sethostname 3 .
+In the current jail implementation, the ability to set the hostname from
+within the jail can impact management tools relying on the accuracy of jail
+information in
+.Pa /proc .
+As such, this should be disabled in environments where privileged access to
+jails is given out to untrusted parties.
+.It Va security.jail.socket_unixiproute_only
+The jail functionality binds an IPv4 address to each jail, and limits
+access to other network addresses in the IPv4 space that may be available
+in the host environment.
+However, jail is not currently able to limit access to other network
+protocol stacks that have not had jail functionality added to them.
+As such, by default, processes within jails may only access protocols
+in the following domains:
+.Dv PF_LOCAL , PF_INET ,
+and
+.Dv PF_ROUTE ,
+permitting them access to
+.Ux
+domain sockets,
+IPv4 addresses, and routing sockets.
+To enable access to other domains, this MIB variable may be set to
+0.
+.It Va security.jail.sysvipc_allowed
+This MIB entry determines whether or not processes within a jail have access
+to System V IPC primitives.
+In the current jail implementation, System V primitives share a single
+namespace across the host and jail environments, meaning that processes
+within a jail would be able to communicate with (and potentially interfere
+with) processes outside of the jail, and in other jails.
+As such, this functionality is disabled by default, but can be enabled
+by setting this MIB entry to 1.

+.Sh HISTORY
+The

+command appeared in
+.Fx 4.0 .
+.Sh AUTHORS
+.An -nosplit
+The jail feature was written by
+.An Poul-Henning Kamp
+for R&D Associates
+.Pa http://www.rndassociates.com/
+who contributed it to
+.Fx .
+.Pp
+.An Robert Watson
+wrote the extended documentation, found a few bugs, added
+a few new features, and cleaned up the userland jail environment.
+.Sh BUGS
+Jail currently lacks strong management functionality, such as the ability
+to deliver signals to all processes in a jail, and to allow access to
+specific jail information via
+.Xr ps 1
+as opposed to
+.Xr procfs 5 .
+Similarly, it might be a good idea to add an
+address alias flag such that daemons listening on all IPs
+.Pq Dv INADDR_ANY
+will not bind on that address, which would facilitate building a safe
+host environment such that host daemons do not impose on services offered
+from within jails.
+Currently, the simplist answer is to minimize services
+offered on the host, possibly limiting it to services offered from
+.Xr inetd 8
+which is easily configurable.

+section).
+.It Fl L Ar keymap_file
+Load keyboard map file from
+.Ar keymap_file
+and write the
+.Ft "struct keymap"
+compiled from it to stdout.
+This option is primarily intended for programmers and is probably
+of little use under normal circumstances.
+.El
+.Sh ENVIRONMENT
+The environment variable
+.Ev KEYMAP_PATH
+can hold an alternative path to the keyboard map files.
+.Sh KEYBOARD CONFIGURATION
+.Ss Boot Time Configuration
+You may set variables in

+.Sh NAME
+.Nm kbdmap
+.Nd keyboard map file format for kbdcontrol
+.Sh SYNOPSIS
+.Nm
+.Sh DESCRIPTION
+A
+.Nm
+file describes how the keys on a keyboard should behave.
+These files can be loaded
+using
+.Xr kbdcontrol 1 ,
+or
+.Xr kbdmap 1
+can be used to select one of the default
+.Nm
+files interactively.
+A
+.Nm
+file can be specified in
+.Xr rc.conf 5 ,
+to be loaded
+at boot time.
+The current keymap may also be printed using
+.Xr kbdcontrol 1 .
+.Pp
+Each line in the file
+can describe a key or an accent.
+A
+.Ql #
+character begins a comment,
+which extends to the end of the line.
+.Pp
+The description of a key
+begins with the scancode for that key.
+Then the effect of the key
+under combinations of
+shift,
+control
+and alt
+are listed in the following order:
+no modifier,
+shift,
+control,
+control and shift,
+alt,
+alt and shift,
+alt and control,
+alt and control and shift.
+The action of the key
+under each modifier can be:
+.Bl -tag -width Ar
+.It ' Ns Ar symbol Ns No '
+The symbol the key should produce,
+in single quotes.
+.It Ar decnum
+The
+.Tn ASCII
+value to produce
+as a decimal number
+(see
+.Xr ascii 7 ) .
+For example, 32 for space.
+.It 0x Ns Ar hexnum
+The
+.Tn ASCII
+value to produce
+as a hexadecimal number.
+For example, 0x20 for space.
+.It Ar ctrlname
+One of the standard names
+for the
+.Tn ASCII
+control characters:
+nul,
+soh,
+stx,
+etx,
+eot,
+enq,
+ack,
+bel,
+bs,
+ht,
+nl,
+vt,
+np,
+cr,
+so,
+si,
+dle,
+dc1,
+dc2,
+dc3,
+dc4,
+nak,
+syn,
+etb,
+can,
+em,
+sub,
+esc,
+fs,
+gs,
+rs,
+ns,
+us,
+sp,
+del.
+.It Ar accentname
+By giving one of the accent names,
+the next key pressed will produce
+an accented character
+in accordance with that accent.
+See the description of accents below.
+The accent names are:
+dgra,
+dacu,
+dcir,
+dtil,
+dmac,
+dbre,
+ddot,
+duml,
+ddia,
+dsla,
+drin,
+dced,
+dapo,
+ddac,
+dogo,
+dcar.
+.It fkey Ns Ar N
+Act as the
+.Ar N Ns No th
+function key,
+where
+.Ar N
+is a decimal number.
+.It lshift
+Act as left shift key.
+.It rshift
+Act as right shift key.
+.It clock
+Act as caps lock key.
+.It nlock
+Act as num lock key.
+.It slock
+Act as scroll lock key.
+.It lalt|alt
+Act as left alt key.
+.It btab
+Act as backwards tab.
+.It lctrl|ctrl
+Act as left control key.
+.It rctrl
+Act as right control key.
+.It ralt
+Act as right alt (altgr) key.
+.It alock
+Act as alt lock key.
+.It ashift
+Act as alt shift key.
+.It meta
+Act as meta key.
+.It lshifta|shifta
+Act as left shift key / alt lock.
+.It rshifta
+Act as right shift key / alt lock.
+.It lctrla|ctrla
+Act as left ctrl key / alt lock.
+.It rctrla
+Act as right ctrl key / alt lock.
+.It lalta|alta
+Act as left alt key / alt lock.
+.It ralta
+Act as right alt key / alt lock.
+.It nscr
+Act as switch to next screen.
+.It pscr
+Act as switch to previous screen.
+.It scr Ns Ar N
+Switch to screen
+.Ar N ,
+where
+.Ar N
+is a decimal number.
+.It boot
+Reboot the machine.
+.It halt
+Halt the machine.
+.It pdwn
+Halt the machine
+and attempt to power it down.
+.It debug
+Call the debugger.
+.It susp
+Use APM to suspend power.
+.It saver
+Activate screen saver
+by toggling between splash/text screen.
+.It panic
+Panic the system.
+.It paste
+Act as mouse buffer paste.
+.El
+.Pp
+Finally,
+to complete the description of a key,
+a flag which describes
+the effect of caps lock and num lock
+on that key is given.
+The flag can be
+.Ql C
+to indicate that caps lock affects the key,
+.Ql N
+to indicate that num lock affects the key,
+.Ql B
+to indicate that both
+caps lock and num lock affects the key,
+or
+.Ql O
+to indicate that neither affects the key.
+.Pp
+An accent key works
+by modifying the behavior
+of the next key pressed.
+The description of an accent begins
+with one of the accent names
+given above.
+This is followed
+by the symbol for the accent,
+given in single quotes or
+as a decimal or hexadecimal
+.Tn ASCII
+value.
+This symbol will be produced
+if the accent key is pressed and
+then the space key is pressed.
+.Pp
+The description of the accent key
+continues with a list showing
+how it modifies various symbols,
+by giving pairs made up of the normal symbol and
+the modified symbol
+enclosed in parentheses.
+Both symbols in a pair can be given
+in either single quotes or
+as decimal or
+hexadecimal
+.Tn ASCII
+values.
+.Pp
+For example,
+consider the following extract from a

+This extract
+configures the backtick key on a UK keyboard
+to act as a grave accent key.
+Pressing backtick followed by space
+produces a backtick, and
+pressing a backtick followed by a vowel
+produces the ISO-8859-1 symbol
+for that vowel with a grave accent.

+.Sh DESCRIPTION
+The
+.Nm
+utility allows easy setting of available keymaps.
+The
+.Nm vidfont
+command allows the setting of fonts.
+Both examine a database for the keymaps and fonts.
+Descriptions are in English by default, but may also be
+in other languages.
+These programs are interactive and expect to run
+in a terminal to get required input (e.g., a keymap selection)
+from the user.
+.Pp
+It is strongly recommended to not choose
+.Tn MSDOS
+codepage keymaps
+or fonts.
+Use the
+.Tn ISO
+standard version if available!
+.Tn X11
+does not
+support
+.Tn MSDOS
+codepage.
+.Pp
+The following options are available:
+.Bl -tag -width indent
+.It Fl K
+Run as command
+.Nm .
+.It Fl V
+Run as command
+.Nm vidfont .
+.It Fl d , Fl default
+Use default language.
+Ignore
+.Ev LANG
+environment variable.
+.It Fl h , Fl help
+Print options and exit.
+.It Fl l , Fl lang Ar language
+Use
+.Ar language
+for description and menu
+.It Fl p , Fl print
+Print description  of available keymaps or fonts
+to stdout and exit.
+.It Fl r , Fl restore
+Load default font from
+.Pa /etc/rc.conf .
+.It Fl s , Fl show
+Show currently supported languages and exit.

+.Sh BUGS
+.\" .Nm kbdmap/vidfont
+.\" does not know which font is in use. E.g. if the current font
+.\" is iso-8859-1 and you chose lang 'ru' (for Russian)
+.\" you get funny latin1 characters and not russkij shrift.
+.\"
+The
+.Nm
+and
+.Nm vidfont
+utilities work only on a (virtual) console and not with

+.Dt KEY 8
+.Os
+.Sh NAME
+.Nm keyadmin
+.Nd manually manipulate the kernel key management database
+.Sh SYNOPSIS
+.Nm
+.Op Ar command Op Ar args
+.Sh DESCRIPTION
+The
+.Nm
+command is used to manually enter security associations into the kernel
+key/security association database.  (See
+.Xr key 4 ) .
+.Pp
+Almost any operation offered in the
+.Xr key 4
+API is available to privileged users running
+.Nm .
+Until there is an implementation of an automated key management protocol,
+which will manipulate the key database in a manner similar to how
+.Xr routed 8
+or
+.Xr gated 8
+manipulates the routing tables,
+.Nm
+is the only way of establishing security associations.
+.Pp
+If
+.Nm
+is invoked without any arguments, it will enter an interactive mode, where
+the user can type in
+.Dq Ar command Op Ar args
+interactively, or use
+.Nm
+to enter a single
+.Dq Ar command Op Ar args .
+.Ar Command
+can be one of the following:
+.Bl -inset
+.It Ic del Ar type spi source destination
+.Pp
+Delete a security association between
+.Ar source
+and
+.Ar destination
+of the given
+.Ar type
+and
+.Ar spi .
+Example:
+.Bd -literal
+	delete esp 90125 anderson.yes.org rabin.yes.org
+.Ed
+.It Ic get Ar type spi source destination
+.Pp
+Retrieve (and print) a security association between
+.Ar source
+and
+.Ar destination
+of the given
+.Ar type
+and
+.Ar spi .
+Example:
+.Bd -literal
+	get ah 5150 eddie.vanhalen.com alex.vanhalen.com
+.Ed
+.It Ic dump
+.Pp
+Display the entire security association table.  WARNING:  This prints a lot
+of data.
+.It Ic load Ar filename
+.Pp
+Load security association information from a file formatted as documented in
+.Xr keys 5 .
+If
+.Dq -
+is specified for the
+.Ar filename ,
+load keys from the standard input.
+.It Ic save Ar filename
+.Pp
+Save security association information to a file formatted as documented in
+.Xr keys 5 .
+If
+.Dq -
+is specified for the
+.Ar filename ,
+place the key file out on the standard output.  (This can be used as a sort
+of lightweight
+.Ic dump
+command.)
+NOTE:  The
+.Ic save
+command must create a new file; it will not write into an
+existing file.  This is to prevent writing into a world-readable file, or a
+named pipe or UNIX socket (see
+.Xr socket 2
+and
+.Xr mkfifo 1 ) .
+.It Ic help Op command
+.Pp
+Offer brief help without an argument, or slightly more specific help on a
+particular command.
+.It Ic flush
+.Pp
+Erase all entries in the kernel security association table.
+.El
+.Pp
+The following values for
+.Ar command
+are only available by using
+.Nm
+in its interactive mode of operation:
+.Bl -inset
+.It Ic add Ar type spi source destination transform key
+.Op Ar iv
+.Pp
+Add a security association of a particular
+.Ar type
+and
+.Ar spi
+from a
+.Ar source
+to a
+.Ar destination ,
+using a particular
+.Ar transform
+and
+.Ar key .
+If a transform requires an initialization vector, the
+.Ar iv
+argument contains it.  This command is available only in interactive mode
+because
+.Nm
+makes no attempt to destroy its argument vector after use.  A malicious user
+of the
+.Xr ps 1
+command could determine security keys if
+.Ic add
+were allowed to be used straight from the command line.  Example:
+.Bd -literal
+	add esp 2112 temples.syrinx.org priests.syrinx.org des-cbc \\
+		a652a476a652a476 87ac9876deac9876
+.Ed
+.It Ic exit
+.It Ic quit
+.Pp
+Exit interaction with
+.Nm .
+An EOF will also end interaction with
+.Nm .
+.El
+.Sh SEE ALSO
+.Xr ipsec 4 ,
+.Xr key 4 ,
+.Xr route 4 ,
+.Xr gated 8 ,
+.Xr routed 8
+.Sh HISTORY
+The
+.Nm
+command first appeared in NRL's
+.Bx 4.4
+IPv6 networking distribution.
+.Nm Keyadmin
+started its life as a pipe dream thought up by Dan McDonald, and came to
+life through the excruciating efforts of Ran Atkinson, Dan McDonald,
+Craig Metz, and Bao Phan.
+The NRL version of the program was originally called
+.Nm key ,
+but was renamed to
+.Nm
+because of the conflict with
+.Xr key 1 .
+.Sh BUGS
+.Nm Keyadmin
+needs a -n flag like
+.Xr route 8
+to avoid name lookups.
+.Pp
+The
+.Ic dump
+and
+.Ic save
+commands currently display the first 30 or so entries.

+.Op Fl D
+.Op Fl n
+.Op Fl p Ar path
+.Op Fl v
+.Sh DESCRIPTION
+.Nm Keyserv
+is a daemon that is used for storing the
+private encryption keys of each
+user logged into the system.
+These encryption keys are used for accessing
+secure network services such as secure NFS.
+.Pp
+Normally, root's key is read from the file
+.Pa /etc/.rootkey
+when the daemon is started.
+This is useful during power-fail reboots
+when no one is around to type a password.
+.Pp
+If a client with no secret key calls
+.Nm ,
+then the key of user
+.Em nobody
+is used instead as the default key.
+.Pp
+The following options are available:
+.Bl -tag -width indent
+.It Fl d
+Disable the use of default keys for
+.Em nobody .
+.It Fl D
+Run in debugging mode and log all requests to
+.Nm .
+.It Fl n
+Root's secret key is not read from
+.Pa /etc/.rootkey .
+Instead,
+.Nm
+prompts the user for the password to decrypt
+root's key stored in the
+.Pa /etc/publickey
+database and then stores the decrypted key in
+.Pa /etc/.rootkey
+for future use.
+This option is useful if the
+.Pa /etc/.rootkey
+file ever gets out of date or corrupted.
+.It Fl p Ar path
+Specify where to search for
+.Pa libdes.so.3 .
+Default is
+.Pa /usr/lib .
+.It Fl v
+Display status of DES support (enabled/disabled).

+.Sh NAME
+.Nm kgmon
+.Nd generate a dump of the operating system's profile buffers
+.Sh SYNOPSIS
+.Nm
+.Op Fl Bbhpr
+.Op Fl M core
+.Op Fl N system
+.Sh DESCRIPTION
+.Nm Kgmon
+is a tool used when profiling the operating system.
+When no arguments are supplied,
+.Nm
+indicates the state of operating system profiling as running,
+off, or not configured.
+(see
+.Xr config 8 )
+If the
+.Fl p
+flag is specified,
+.Nm
+extracts profile data from the operating system and produces a
+.Pa gmon.out
+file suitable for later analysis by
+.Xr gprof 1 .
+.Pp
+The options are as follows:
+.Bl -tag -width Ds
+.It Fl B
+Resume the collection of high resolution profile data.
+.It Fl b
+Resume the collection of low resolution profile data.
+.It Fl h
+Stop the collection of profile data.
+.It Fl p
+Dump the contents of the profile buffers into a
+.Pa gmon.out
+file.
+.It Fl r
+Reset all the profile buffers.
+If the
+.Fl p
+flag is also specified, the
+.Pa gmon.out
+file is generated before the buffers are reset.
+.It Fl M
+Extract values associated with the name list from the specified core
+instead of the default
+.Pa /dev/kmem .
+.It Fl N
+Extract the name list from the specified system instead of the
+default
+.Pa /boot/kernel/kernel .
+.El
+.Pp
+If neither
+.Fl B
+nor
+.Fl b
+nor
+.Fl h
+is specified, the state of profiling collection remains unchanged.
+For example, if the
+.Fl p
+flag is specified and profile data is being collected,
+profiling will be momentarily suspended,
+the operating system profile buffers will be dumped,
+and profiling will be immediately resumed.
+.Pp
+The profile buffers should be reset when the resolution
+of the profile data is changed.
+.Sh FILES
+.Bl -tag -width /dev/kmemx -compact
+.It Pa /boot/kernel/kernel
+the default system
+.It Pa /dev/kmem
+the default memory
+.El
+.Sh SEE ALSO
+.Xr gprof 1 ,
+.Xr config 8
+.Sh DIAGNOSTICS
+Users with only read permission on
+.Pa /dev/kmem
+cannot change the state
+of profiling collection.
+They can get a
+.Pa gmon.out
+file with the warning that the data may be
+inconsistent if profiling is in progress.
+.Sh HISTORY
+The
+.Nm
+command appeared in
+.Bx 4.2 .

+.Sh NAME
+.Nm kgzip
+.Nd compress a kernel
+.Sh SYNOPSIS
+.Nm
+.Op Fl cv
+.Op Fl f Ar format
+.Op Fl l Ar loader
+.Op Fl o Ar output
+.Ar file
+.Sh DESCRIPTION
+The
+.Nm
+utility compresses a kernel or some other bootable binary.  Operation
+is in two phases as follows:
+.Bl -enum
+.It
+A load image of the executable file is built which omits all but
+the
+.Sq text
+and
+.Sq data
+segments.  This image is compressed using
+.Xr gzip 1
+and output as data in relocatable object format.
+.It
+The object file is linked with a special self-hosting loader, producing
+an executable suitable for booting with either the second- or
+third-level bootstraps.
+.El
+.Pp
+Supported object formats are 32-bit ELF and a.out ZMAGIC.
+.Pp
+If the
+.Ar file
+operand has a
+.Sq .o
+suffix, input is assumed to be for the link phase, and the first phase
+is omitted.
+.Pp
+The options are:
+.Bl -tag -width Fl
+.It Fl c
+Omit the link phase.
+.It Fl v
+Display object file information.
+.It Fl f Ar format
+Use
+.Ar format
+as the output format, where
+.Ar format
+is
+.Sq aout
+or
+.Sq elf .
+The default format is ELF.
+.It Fl l Ar loader
+Link
+.Ar loader
+as the loader.
+.It Fl o Ar output
+Name the output file
+.Ar output .
+The default is to use the input name with the suffix
+.Sq .o
+(for relocatables) or
+.Sq .kgz
+(for executables).
+.El
+.Sh NOTES
+Global variables equivalent to the following are defined in the output:
+.Bd -literal
+struct kgz_hdr {
+    char	ident[4];	/* identification: "KGZ" */
+    uint32_t	dload;		/* decoded image load address */
+    uint32_t	dsize;		/* decoded image size */
+    uint32_t	isize;		/* image size in memory */
+    uint32_t	entry;		/* entry point */
+    uint32_t	nsize;		/* encoded image size */
+} kgz;
+
+uint8_t kgz_ndata[];		/* encoded data */
+.Ed
+.Pp
+The encoded data is simply
+.Xr gzip 1
+output: a header (with no optional fields); compressed data; and 32-bit
+CRC and size values.
+.Sh FILES
+.Bl -tag -width /usr/lib/kgzldr.o -compact
+.It Pa /usr/lib/kgzldr.o
+The default loader
+.El
+.Sh SEE ALSO
+.Xr gzip 1 ,
+.Xr ld 1 ,
+.Xr a.out 5 ,
+.Xr elf 5 ,
+.Xr boot 8 ,
+.Xr loader 8
+.Sh DIAGNOSTICS
+.Ex -std
+.Sh AUTHORS
+.An Robert Nordier Aq rnordier@FreeBSD.org .
+.Sh BUGS
+As symbols are lost, the usefulness of this utility for compressing
+kernels is limited to situations where
+.Xr loader 8
+cannot be used; otherwise the preferred method of compressing a kernel
+is simply to
+.Xr gzip 1
+it.

+.Sh NAME
+.Nm kldxref
+.Nd generate hints for the kernel loader
+.Sh SYNOPSIS
+.Nm
+.Op Fl Rdv
+.Op Fl f Ar file
+.Op Ar path ...
+.Sh DESCRIPTION
+The
+.Nm
+command is used to generate hint files which list modules, their
+version numbers, and the files that contain them.
+These hints are used by the kernel loader to determine where to find a
+particular KLD module.
+.Pp
+A separate hint file is generated for each directory listed on the
+command line that contains modules.
+If no hint records are generated for a particular directory, no hint
+file is created, and the preexisting hint file (if there was one in
+that directory) is removed.
+.Pp
+The following options are available:
+.Bl -tag -width ".Fl f Ar file"
+.It Fl R
+Recurse into subdirectories.
+.It Fl d
+Do not generate a hint file, but print module metadata on standard
+output.
+.It Fl f Ar file
+Specify a different name for the hint files than
+.Pa linker.hints .
+.It Fl v
+Operate in verbose mode.
+.El
+.Sh EXAMPLES
+To build hint files for both standard and add-on modules:
+.Pp
+.Dl "kldxref /boot/kernel /modules"
+.Pp
+To build hint files for all installed kernels:
+.Pp
+.Dl "kldxref -R /boot"

+.Nd indicate last login time of users
+.Sh SYNOPSIS
+.Nm
+.Op Ar user ...
+.Sh DESCRIPTION
+.Nm
+will list the last login session of each specified
+.Ar user ,
+or for all users by default.  Each line of output contains
+the user name, the tty from which the session was conducted, any
+hostname, and the start time for the session.
+.Pp
+If more than one
+.Ar user
+is given, the session information for each user is printed in
+the order given on the command line.  Otherwise, information
+for all users is printed, sorted by uid.
+.Pp
+.Nm
+differs from
+.Xr last 1
+in that it only prints information regarding the very last login session.
+The last login database is never turned over or deleted in standard usage.

+lpd \- line printer daemon
+.PP
+The program
+.IR lpd (8),
+usually invoked at boot time from the /etc/rc file, acts as
+a master server for coordinating and controlling
+the spooling queues configured in the printcap file.
+When
+.I lpd
+is started it makes a single pass through the
+.I printcap
+database restarting any printers that have jobs.
+In normal operation
+.I lpd
+listens for service requests on multiple sockets,
+one in the UNIX domain (named ``/dev/printer'') for
+local requests, and one in the Internet domain
+(under the ``printer'' service specification)
+for requests for printer access from off machine;
+see \fIsocket\fP\|(2) and \fIservices\fP\|(5)
+for more information on sockets and service
+specifications, respectively.
+.I Lpd
+spawns a copy of itself to process the request; the master daemon
+continues to listen for new requests.
+.PP
+Clients communicate with 
+.I lpd
+using a simple transaction oriented protocol.
+Authentication of remote clients is done based
+on the ``privilege port'' scheme employed by
+\fIrshd\fP\|(8C) and \fIrcmd\fP\|(3X).
+The following table shows the requests 
+understood by
+.IR lpd .
+In each request the first byte indicates the
+``meaning'' of the request, followed by the name
+of the printer to which it should be applied.  Additional
+qualifiers may follow, depending on the request.

+.PP
+The \fIlpr\fP\|(1) command
+is used by users to enter a print job in a local queue and to notify
+the local
+.I lpd
+that there are new jobs in the spooling area.
+.I Lpd
+either schedules the job to be printed locally, or if
+printing remotely, attempts to forward
+the job to the appropriate machine.
+If the printer cannot be opened or the destination
+machine is unreachable, the job will remain queued until it is
+possible to complete the work.
+.NH 2
+lpq \- show line printer queue
+.PP
+The \fIlpq\fP\|(1)
+program works recursively backwards displaying the queue of the machine with
+the printer and then the queue(s) of the machine(s) that lead to it.
+.I Lpq
+has two forms of output: in the default, short, format it
+gives a single line of output per queued job; in the long 
+format it shows the list of files, and their sizes, that
+comprise a job.
+.NH 2
+lprm \- remove jobs from a queue
+.PP
+The \fIlprm\fP\|(1) command deletes jobs from a spooling
+queue.  If necessary, \fIlprm\fP will first kill off a
+running daemon that is servicing the queue and restart
+it after the required files are removed.  When removing
+jobs destined for a remote printer, \fIlprm\fP acts
+similarly to \fIlpq\fP except it first checks locally
+for jobs to remove and then
+tries to remove files in queues off-machine.
+.NH 2
+lpc \- line printer control program
+.PP
+The
+.IR lpc (8)
+program is used by the system administrator to control the
+operation of the line printer system.  
+For each line printer configured in /etc/printcap,
+.I lpc
+may be used to:
+.IP \(bu
+disable or enable a printer,
+.IP \(bu
+disable or enable a printer's spooling queue,
+.IP \(bu
+rearrange the order of jobs in a spooling queue,
+.IP \(bu
+find the status of printers, and their associated
+spooling queues and printer daemons.

+Access control
+.PP
+The printer system maintains protected spooling areas so that
+users cannot circumvent printer accounting or
+remove files other than their own.
+The strategy used to maintain protected
+spooling areas is as follows:
+.IP \(bu 3
+The spooling area is writable only by a \fIdaemon\fP user
+and \fIdaemon\fP group.
+.IP \(bu 3
+The \fIlpr\fP program runs set-user-id to \fIroot\fP and
+set-group-id to group \fIdaemon\fP.  The \fIroot\fP access permits
+reading any file required. Accessibility is verified
+with an \fIaccess\fP\|(2) call.  The group ID
+is used in setting up proper ownership of files
+in the spooling area for \fIlprm\fP.
+.IP \(bu 3
+Control files in a spooling area are made with \fIdaemon\fP
+ownership and group ownership \fIdaemon\fP.  Their mode is 0660.
+This insures control files are not modified by a user
+and that no user can remove files except through \fIlprm\fP.
+.IP \(bu 3
+The spooling programs,
+\fIlpd\fP, \fIlpq\fP, and \fIlprm\fP run set-user-id to \fIroot\fP
+and set-group-id to group \fIdaemon\fP to access spool files and printers.
+.IP \(bu 3
+The printer server, \fIlpd\fP,
+uses the same verification procedures as \fIrshd\fP\|(8C)
+in authenticating remote clients.  The host on which a client
+resides must be present in the file /etc/hosts.equiv or /etc/hosts.lpd and
+the request message must come from a reserved port number.
+.PP
+In practice, none of \fIlpd\fP, \fIlpq\fP, or
+\fIlprm\fP would have to run as user \fIroot\fP if remote
+spooling were not supported.  In previous incarnations of
+the printer system \fIlpd\fP ran set-user-id to \fIdaemon\fP,
+set-group-id to group \fIspooling\fP, and \fIlpq\fP and \fIlprm\fP ran
+set-group-id to group \fIspooling\fP.

+.NH 1
+Setting up
+.PP
+The 4.3BSD release comes with the necessary programs 
+installed and with the default line printer queue
+created.  If the system must be modified, the
+makefile in the directory /usr/src/usr.lib/lpr
+should be used in recompiling and reinstalling
+the necessary programs.
+.PP
+The real work in setting up is to create the
+.I printcap
+file and any printer filters for printers not supported
+in the distribution system.
+.NH 2
+Creating a printcap file
+.PP
+The 
+.I printcap
+database contains one or more entries per printer.
+A printer should have a separate spooling directory;
+otherwise, jobs will be printed on
+different printers depending on which printer daemon starts first.
+This section describes how to create entries for printers that do not
+conform to the default printer description (an LP-11 style interface to a
+standard, band printer).
+.NH 3
+Printers on serial lines
+.PP
+When a printer is connected via a serial communication line
+it must have the proper baud rate and terminal modes set.
+The following example is for a DecWriter III printer connected
+locally via a 1200 baud serial line.
+.DS
+.DT
+lp|LA-180 DecWriter III:\e
+	:lp=/dev/lp:br#1200:fs#06320:\e
+	:tr=\ef:of=/usr/lib/lpf:lf=/usr/adm/lpd-errs:
+.DE
+The
+.B lp
+entry specifies the file name to open for output. Here it could
+be left out since ``/dev/lp'' is the default.
+The
+.B br
+entry sets the baud rate for the tty line and the
+.B fs
+entry sets CRMOD, no parity, and XTABS (see \fItty\fP\|(4)).
+The
+.B tr
+entry indicates that a form-feed should be printed when the queue
+empties so the paper can be torn off without turning the printer off-line and
+pressing form feed.
+The
+.B of
+entry specifies the filter program
+.I lpf
+should be used for printing the files;
+more will be said about filters later.
+The last entry causes errors
+to be written to the file ``/usr/adm/lpd-errs''
+instead of the console.  Most errors from \fIlpd\fP are logged using
+\fIsyslogd\fP\|(8) and will not be logged in the specified file.  The
+filters should use \fIsyslogd\fP to report errors; only those that
+write to standard error output will end up with errors in the \fBlf\fP file.
+(Occasionally errors sent to standard error output have not appeared
+in the log file; the use of \fIsyslogd\fP is highly recommended.)
+.NH 3
+Remote printers
+.PP
+Printers that reside on remote hosts should have an empty
+.B lp
+entry.
+For example, the following printcap entry would send output to the printer
+named ``lp'' on the machine ``ucbvax''.
+.DS
+.DT
+lp|default line printer:\e
+	:lp=:rm=ucbvax:rp=lp:sd=/usr/spool/vaxlpd:
+.DE
+The
+.B rm
+entry is the name of the remote machine to connect to; this name must
+be a known host name for a machine on the network.
+The
+.B rp
+capability indicates
+the name of the printer on the remote machine is ``lp'';
+here it could be left out since this is the default value.
+The
+.B sd
+entry specifies ``/usr/spool/vaxlpd''
+as the spooling directory instead of the
+default value of ``/usr/spool/lpd''.
+.NH 2
+Output filters
+.PP
+Filters are used to handle device dependencies and to
+do accounting functions.  The output filtering of
+.B of
+is used when accounting is
+not being done or when all text data must be passed through a filter.
+It is not intended to do accounting since it is started only once,
+all text files are filtered through it, and no provision is made for passing
+owners' login name, identifying the beginning and ending of jobs, etc.
+The other filters (if specified) are started for each file
+printed and do accounting if there is an
+.B af
+entry.
+If entries for both
+.B of
+and other filters are specified,
+the output filter is used only to print the banner page;
+it is then stopped to allow other filters access to the printer.
+An example of a printer that requires output filters
+is the Benson-Varian.
+.DS
+.DT
+va|varian|Benson-Varian:\e
+	:lp=/dev/va0:sd=/usr/spool/vad:of=/usr/lib/vpf:\e
+	:tf=/usr/lib/rvcat:mx#2000:pl#58:px=2112:py=1700:tr=\ef:
+.DE
+The
+.B tf
+entry specifies ``/usr/lib/rvcat'' as the filter to be
+used in printing \fItroff\fP\|(1) output.
+This filter is needed to set the device into print mode
+for text, and plot mode for printing
+.I troff
+files and raster images (see \fIva\fP\|(4V)).
+Note that the page length is set to 58 lines by the
+.B pl
+entry for 8.5" by 11" fan-fold paper.
+To enable accounting, the varian entry would be
+augmented with an
+.B af
+filter as shown below.
+.DS
+.DT
+va|varian|Benson-Varian:\e
+	:lp=/dev/va0:sd=/usr/spool/vad:of=/usr/lib/vpf:\e

+	:mx#2000:pl#58:px=2112:py=1700:tr=\ef:
+.DE
+.NH 2
+Access Control
+.PP
+Local access to printer queues is controlled with the
+.B rg
+printcap entry.
+.DS
+	:rg=lprgroup:
+.DE
+Users must be in the group
+.I lprgroup
+to submit jobs to the specified printer.
+The default is to allow all users access.
+Note that once the files are in the local queue, they can be printed
+locally or forwarded to another host depending on the configuration.
+.PP
+Remote access is controlled by listing the hosts in either the file
+/etc/hosts.equiv or /etc/hosts.lpd, one host per line. Note that
+.IR rsh (1)
+and
+.IR rlogin (1)
+use /etc/hosts.equiv to determine which hosts are equivalent for allowing logins
+without passwords. The file /etc/hosts.lpd is only used to control
+which hosts have line printer access.
+Remote access can be further restricted to only allow remote users with accounts
+on the local host to print jobs by using the \fBrs\fP printcap entry.

+Output filter specifications
+.PP
+The filters supplied with 4.3BSD
+handle printing and accounting for most common
+line printers, the Benson-Varian, the wide (36") and
+narrow (11") Versatec printer/plotters. For other devices or accounting
+methods, it may be necessary to create a new filter.
+.PP
+Filters are spawned by \fIlpd\fP
+with their standard input the data to be printed, and standard output
+the printer.  The standard error is attached to the
+.B lf
+file for logging errors or \fIsyslogd\fP may be used for logging errors.
+A filter must return a 0 exit
+code if there were no errors, 1 if the job should be reprinted,
+and 2 if the job should be thrown away.
+When \fIlprm\fP
+sends a kill signal to the \fIlpd\fP process controlling
+printing, it sends a SIGINT signal 
+to all filters and descendents of filters.
+This signal can be trapped by filters that need
+to do cleanup operations such as
+deleting temporary files.
+.PP
+Arguments passed to a filter depend on its type.
+The
+.B of
+filter is called with the following arguments.
+.DS
+\fIfilter\fP \fB\-w\fPwidth \fB\-l\fPlength
+.DE
+The \fIwidth\fP and \fIlength\fP values come from the
+.B pw
+and
+.B pl

+filter is passed the following parameters.
+.DS
+\fIfilter\fP [\|\fB\-c\fP\|] \fB\-w\fPwidth \fB\-l\fPlength \fB\-i\fPindent \fB\-n\fP login \fB\-h\fP host accounting_file
+.DE
+The
+.B \-c
+flag is optional, and only supplied when control characters
+are to be passed uninterpreted to the printer (when using the
+.B \-l
+option of
+.I lpr
+to print the file).
+The
+.B \-w
+and
+.B \-l
+parameters are the same as for the
+.B of
+filter.
+The

+Line printer Administration
+.PP
+The
+.I lpc
+program provides local control over line printer activity.
+The major commands and their intended use will be described.
+The command format and remaining commands are described in
+.IR lpc (8).
+.LP
+\fBabort\fP and \fBstart\fP
+.IP
+.I Abort
+terminates an active spooling daemon on the local host immediately and
+then disables printing (preventing new daemons from being started by
+.IR lpr ).
+This is normally used to forcibly restart a hung line printer daemon
+(i.e., \fIlpq\fP reports that there is a daemon present but nothing is
+happening).  It does not remove any jobs from the queue
+(use the \fIlprm\fP command instead).
+.I Start
+enables printing and requests \fIlpd\fP to start printing jobs.
+.LP
+\fBenable\fP and \fBdisable\fP
+.IP
+\fIEnable\fP and \fIdisable\fP allow spooling in the local queue to be
+turned on/off.
+This will allow/prevent
+.I lpr
+from putting new jobs in the spool queue.  It is frequently convenient
+to turn spooling off while testing new line printer filters since the
+.I root
+user can still use
+.I lpr
+to put jobs in the queue but no one else can.
+The other main use is to prevent users from putting jobs in the queue
+when the printer is expected to be unavailable for a long time.
+.LP
+\fBrestart\fP
+.IP
+.I Restart
+allows ordinary users to restart printer daemons when
+.I lpq
+reports that there is no daemon present.
+.LP
+\fBstop\fP
+.IP
+.I Stop
+halts a spooling daemon after the current job completes;
+this also disables printing.  This is a clean way to shutdown a
+printer to do maintenance, etc.  Note that users can still enter jobs in a
+spool queue while a printer is
+.IR stopped .
+.LP
+\fBtopq\fP
+.IP
+.I Topq
+places jobs at the top of a printer queue.  This can be used
+to reorder high priority jobs since
+.I lpr
+only provides first-come-first-serve ordering of jobs.

+.NH 1
+Troubleshooting
+.PP
+There are several messages that may be generated by the
+the line printer system.  This section
+categorizes the most common and explains the cause
+for their generation.  Where the message implies a failure,
+directions are given to remedy the problem.
+.PP
+In the examples below, the name
+.I printer
+is the name of the printer from the
+.I printcap
+database.
+.NH 2
+LPR
+.SH
+lpr: \fIprinter\fP\|: unknown printer
+.IP
+The
+.I printer
+was not found in the
+.I printcap
+database.  Usually this is a typing mistake; however, it may indicate
+a missing or incorrect entry in the /etc/printcap file.
+.SH
+lpr: \fIprinter\fP\|: jobs queued, but cannot start daemon.
+.IP
+The connection to 
+.I lpd
+on the local machine failed. 
+This usually means the printer server started at
+boot time has died or is hung.  Check the local socket
+/dev/printer to be sure it still exists (if it does not exist,
+there is no 
+.I lpd
+process running). 
+Usually it is enough to get a super-user to type the following to
+restart
+.IR lpd .
+.DS
+% /usr/lib/lpd
+.DE
+You can also check the state of the master printer daemon with the following.
+.DS
+% ps l`cat /usr/spool/lpd.lock`
+.DE
+.IP
+Another possibility is that the
+.I lpr
+program is not set-user-id to \fIroot\fP, set-group-id to group \fIdaemon\fP.
+This can be checked with
+.DS
+% ls \-lg /usr/ucb/lpr
+.DE
+.SH
+lpr: \fIprinter\fP\|: printer queue is disabled
+.IP
+This means the queue was turned off with
+.DS
+% lpc disable \fIprinter\fP
+.DE
+to prevent 
+.I lpr
+from putting files in the queue.  This is normally
+done by the system manager when a printer is
+going to be down for a long time.  The
+printer can be turned back on by a super-user with
+.IR lpc .
+.NH 2
+LPQ
+.SH
+waiting for \fIprinter\fP to become ready (offline ?)
+.IP
+The printer device could not be opened by the daemon. 
+This can happen for several reasons,
+the most common is that the printer is turned off-line.
+This message can also be generated if the printer is out
+of paper, the paper is jammed, etc.
+The actual reason is dependent on the meaning
+of error codes returned by system device driver. 
+Not all printers supply enough information 
+to distinguish when a printer is off-line or having
+trouble (e.g. a printer connected through a serial line). 
+Another possible cause of this message is
+some other process, such as an output filter,
+has an exclusive open on the device.  Your only recourse
+here is to kill off the offending program(s) and
+restart the printer with
+.IR lpc .
+.SH
+\fIprinter\fP is ready and printing
+.IP
+The
+.I lpq
+program checks to see if a daemon process exists for
+.I printer
+and prints the file \fIstatus\fP located in the spooling directory.
+If the daemon is hung, a super user can use
+.I lpc
+to abort the current daemon and start a new one.
+.SH
+waiting for \fIhost\fP to come up
+.IP
+This implies there is a daemon trying to connect to the remote
+machine named
+.I host
+to send the files in the local queue. 
+If the remote machine is up,
+.I lpd
+on the remote machine is probably dead or
+hung and should be restarted as mentioned for
+.IR lpr .
+.SH
+sending to \fIhost\fP
+.IP
+The files should be in the process of being transferred to the remote
+.IR host .
+If not, the local daemon should be aborted and started with
+.IR lpc .
+.SH
+Warning: \fIprinter\fP is down
+.IP
+The printer has been marked as being unavailable with
+.IR lpc .
+.SH
+Warning: no daemon present
+.IP
+The \fIlpd\fP process overseeing
+the spooling queue, as specified in the ``lock'' file
+in that directory, does not exist.  This normally occurs
+only when the daemon has unexpectedly died.
+The error log file for the printer and the \fIsyslogd\fP logs
+should be checked for a
+diagnostic from the deceased process.
+To restart an \fIlpd\fP, use
+.DS
+% lpc restart \fIprinter\fP
+.DE
+.SH
+no space on remote; waiting for queue to drain
+.IP
+This implies that there is insufficient disk space on the remote.
+If the file is large enough, there will never be enough space on
+the remote (even after the queue on the remote is empty). The solution here
+is to move the spooling queue or make more free space on the remote.
+.NH 2
+LPRM
+.SH
+lprm: \fIprinter\fP\|: cannot restart printer daemon
+.IP
+This case is the same as when
+.I lpr
+prints that the daemon cannot be started.
+.NH 2
+LPD
+.PP
+The
+.I lpd
+program can log many different messages using \fIsyslogd\fP\|(8).
+Most of these messages are about files that can not
+be opened and usually imply that the
+.I printcap
+file or the protection modes of the files are
+incorrect.   Files may also be inaccessible if people
+manually manipulate the line printer system (i.e. they
+bypass the
+.I lpr
+program). 
+.PP
+In addition to messages generated by 
+.IR lpd ,
+any of the filters that
+.I lpd
+spawns may log messages using \fIsyslogd\fP or to the error log file
+(the file specified in the \fBlf\fP entry in \fIprintcap\fP\|).
+.NH 2
+LPC
+.PP
+.SH
+couldn't start printer
+.IP
+This case is the same as when
+.I lpr
+reports that the daemon cannot be started.
+.SH
+cannot examine spool directory
+.IP
+Error messages beginning with ``cannot ...'' are usually because of
+incorrect ownership or protection mode of the lock file, spooling
+directory or the
+.I lpc
+program.

+.Os
+.Sh NAME
+.Nm chkprintcap
+.Nd check validity of entries in the print spooler database
+.Sh SYNOPSIS
+.Nm
+.Op Fl d
+.Op Fl f Ar printcap
+.Sh DESCRIPTION
+.Nm Chkprintcap
+scans a
+.Xr printcap 5
+database
+(named by the
+.Ar printcap
+argument, or by default
+.Pa /etc/printcap ) ,
+looking for entries which are invalid in one way or another.
+The following checks are currently implemented:
+.Bl -enum -offset indent
+.It
+.Sq Li tc=
+references were properly expanded
+.It
+.Sq Li tc=
+references did not form a loop
+.It
+No two printers share the same spool directory
+.Sq ( Li sd=
+capability).
+.El
+.Pp
+.Nm Chkprintcap
+exits with a status equal to the number of errors encountered before
+processing stopped.  (In some cases, processing can stop before the
+entire file is scanned.)
+.Pp
+If the
+.Fl d
+flag is given,
+.Nm
+will attempt to create any missing spool directories, giving them
+.Sq Li u=rwx,go=rx
+(0755) mode, group
+.Sq Li daemon ,
+and the owner specified by the
+.Sq Li du=
+capability in the database (default 1, which corresponds to user
+.Sq Li daemon ) .
+.Sh SEE ALSO
+.Xr lpr 1 ,
+.Xr printcap 5 ,
+.Xr lpd 8
+.Sh AUTHORS
+The
+.Nm
+command was written by
+.An Garrett A. Wollman Aq wollman@lcs.mit.edu .
+.Sh BUGS
+Not enough sanity-checking is done.  At a minimum, the ownership and
+mode of the spool directories should also be checked.  Other
+parameters whose value could cause
+.Xr lpd 8
+to fail should be diagnosed.

+ *	Control-files (cf*) have the following format.
+ *
+ *	Each control-file describes a single job.  It will list one or more
+ *	"datafiles" (df*) which should be copied to some printer.  Usually
+ *	there is only one datafile per job.  For the curious, RFC 1179 is an
+ *	informal and out-of-date description of lpr/lpd circa 1990.
+ *
+ *	Each line in the file gives an attribute of the job as a whole, or one
+ *	of the datafiles in the job, or a "command" indicating something to do
+ *	with one of the datafiles.  Each line starts with an 'id' that indicates
+ *	what that line is there for.  The 'id' is historically a single byte,
+ *	but may be multiple bytes (obviously it would be best if multi-byte ids
+ *	started with some letter not already used as a single-byte id!).
+ *	After the 'id', the remainder of the line will be the value of the
+ *	indicated attribute, or a name of the datafile to be operated on.
+ *
+ *	In the following lists of ids, the ids with a '!' in front of them are
+ *	NOT explicitly supported by this version of lpd, or at least "not yet
+ *	supported".  They are only listed for reference purposes, so people
+ *	won't be tempted to reuse the same id for a different purpose.
+ *
+ *	The following are attributes of the job which should not appear more
+ *	than once in a control file.  Only the 'H' and 'P' lines are required
+ *	by the RFC, but some implementations of lpr won't even get that right.
+ *
+ *	! A   - [used by lprNG]
+ *	  B   - As far as I know, this is never used as a single-byte id.
+ *		Therefore, I intend to use it for multi-byte id codes.
+ *	  C   - "class name" to display on banner page (this is sometimes

+ * that this host will accept print jobs from).  The fact that we're willing
+ * to print jobs from some remote host does not mean that we should blindly
+ * do anything that host tells us to do.
+ *
+ * This is also meant to protect us from errors in other implementations of
+ * lpr, particularly since we may want to use some values from the control
+ * file as environment variables when it comes time to print, or as parameters
+ * to commands which will be exec'ed, or values in statistics records.
+ *
+ * This may also do some "conversions" between how different versions of
+ * lpr or lprNG define the contents of various lines in a control file.
+ *
+ * If there is an error, it returns a pointer to a descriptive error message.
+ * Error messages which are RETURNED (as opposed to syslog-ed) do not include
+ * the printer-queue name.  Let the caller add that if it is wanted.

+.Sh NAME
+.Nm lp
+.Nd front-end to the print spooler
+.Sh SYNOPSIS
+.Nm
+.Op Fl cs
+.Op Fl o Ar option
+.Op Fl d Ar printer
+.Op Fl n Ar num
+.Op Ar name ...
+.Sh DESCRIPTION
+The
+.Nm
+utility is a front-end to the print spooler as required by the
+.St -p1003.2
+specification.  It effectively invokes
+.Xr lpr 1
+with the proper set of arguments.
+.Pp
+It generally prints the named files on the destination printer.
+.Pp
+The following options are available:
+.Bl -tag -width indent
+.It Fl c
+Make the
+.Nm
+command exit only after further access to any of the input files is no
+longer required.  The application can then safely delete or modify the
+files without affecting the output operation.
+.It Fl d Ar dest
+Specify a particular printer.
+If no
+.Fl d
+is provided on the command line, the contents of the environment
+variables
+.Ev LPDEST
+or
+.Ev PRINTER
+(with this precedence)
+are taken as the destination printer.
+.It Fl n Ar num
+Specify that
+.Ar num
+copies of each of the named files shall be printed.
+.It Fl o Ar option
+Printer specific options.
+Not supported, provided only as a compatibility
+option for SVR.
+.It Fl s
+Silent operation.
+Not supported,
+provided only as a compatibility option for
+.St -susv2 .
+.El
+.Sh ENVIRONMENT
+As described above, the variables
+.Ev LPDEST
+and
+.Ev PRINTER
+are examined to select the destination printer.
+.Sh SEE ALSO
+.Xr lpr 1
+.Sh STANDARDS
+The
+.Nm
+command is expected to comply with the
+.St -p1003.2
+specification.
+.Sh AUTHORS
+This implementation of the
+.Nm
+command has been written by
+.An J\(:org Wunsch .
+.Sh BUGS
+The
+.St -p1003.2
+specification does not provide any means to print non-text files.  It
+rather requires the files to be printed to be text files limited to
+reasonable line lengths and printable characters.

+.Sh NAME
+.Nm lpc
+.Nd line printer control program
+.Sh SYNOPSIS
+.Nm
+.Op Ar command Op Ar argument ...
+.Sh DESCRIPTION
+.Nm Lpc
+is used by the system administrator to control the
+operation of the line printer system.
+For each line printer configured in
+.Pa /etc/printcap ,
+.Nm
+may be used to:
+.Bl -bullet -offset indent
+.It
+disable or enable a printer,
+.It
+disable or enable a printer's spooling queue,
+.It
+rearrange the order of jobs in a spooling queue,
+.It
+find the status of printers, and their associated
+spooling queues and printer daemons,
+.It
+change the status message for printer queues (the status message
+may be seen by users as part of the output of the
+.Xr lpq 1 utility).
+.El
+.Pp
+Without any arguments,
+.Nm
+will prompt for commands from the standard input.
+If arguments are supplied,
+.Nm
+interprets the first argument as a command and the remaining
+arguments as parameters to the command.
+The standard input
+may be redirected causing
+.Nm
+to read commands from file.
+Commands may be abbreviated;
+the following is the list of recognized commands.
+.Pp
+.Bl -tag -width indent -compact
+.It Ic \&? Op Ar command ...
+.It Ic help Op Ar command ...
+Print a short description of each command specified in the argument list,
+or, if no argument is given, a list of the recognized commands.
+.Pp
+.It Ic abort Brq Cm all | Ar printer
+Terminate an active spooling daemon on the local host immediately and
+then disable printing (preventing new daemons from being started by
+.Xr lpr 1 )
+for the specified printers.
+.Pp
+.It Ic clean Brq Cm all | Ar printer
+Remove any temporary files, data files, and control files that cannot
+be printed (i.e., do not form a complete printer job)
+from the specified printer queue(s) on the local machine.
+This command will also look for
+.Pa core
+files in spool directory
+for each printer queue, and list any that are found.
+It will not remove any
+.Pa core
+files.
+See also the
+.Ic tclean
+command.
+.Pp
+.It Ic disable Brq Cm all | Ar printer
+Turn the specified printer queues off.
+This prevents new
+printer jobs from being entered into the queue by
+.Xr lpr 1 .
+.Pp
+.It Ic down Bro Cm all | Ar printer ... Brc Cm -msg Ar message ...
+.It Ic down Bro Cm all | Ar printer Brc Ar message ...
+Turn the specified printer queue off, disable printing and put
+.Ar message
+in the printer status file.
+When specifying more than one printer queue, the
+.Ic -msg
+argument is required to separate the list of printers from the text
+that will be the new status message.
+The message doesn't need to be quoted, the
+remaining arguments are treated like
+.Xr echo 1 .
+This is normally used to take a printer down, and let other users
+find out why it is down (the
+.Xr lpq 1
+utility will indicate that the printer is down and will print the
+status message).
+.Pp
+.It Ic enable Brq Cm all | Ar printer
+Enable spooling on the local queue for the listed printers.
+This will allow
+.Xr lpr 1
+to put new jobs in the spool queue.
+.Pp
+.It Ic exit
+.It Ic quit
+Exit from
+.Nm .
+.Pp
+.It Ic restart Brq Cm all | Ar printer
+Attempt to start a new printer daemon.
+This is useful when some abnormal condition causes the daemon to
+die unexpectedly, leaving jobs in the queue.
+.Xr lpq 1
+will report that there is no daemon present when this condition occurs.
+If the user is the super-user,
+try to abort the current daemon first (i.e., kill and restart a stuck daemon).
+.Pp
+.It Ic setstatus Bro Cm all | Ar printer Brc Cm -msg Ar message ...
+Set the status message for the specified printers.
+The
+.Ic -msg
+argument is required to separate the list of printers from the text
+that will be the new status message.
+This is normally used to change the status message when the printer
+queue is no longer active after printing has been disabled, and you
+want to change what users will see in the output of the
+.Xr lpq 1 utility.
+.Pp
+.It Ic start Brq Cm all | Ar printer
+Enable printing and start a spooling daemon for the listed printers.
+.Pp
+.It Ic status Brq Cm all | Ar printer
+Display the status of daemons and queues on the local machine.
+.Pp
+.It Ic stop Brq Cm all | Ar printer
+Stop a spooling daemon after the current job completes and disable
+printing.
+.Pp
+.It Ic tclean Brq Cm all | Ar printer
+This will do a test-run of the
+.Ic clean
+command.
+All the same checking is done, but the command will only print out
+messages saying what a similar
+.Ic clean
+command would do if the user typed it in.
+It will not remove any files.
+Note that the
+.Ic clean
+command is a privileged command, while the
+.Ic tclean
+command is not restricted.
+.Pp
+.It Ic topq Ar printer Xo
+.Op Ar jobnum ...
+.Op Ar user ...
+.Xc
+Place the jobs in the order listed at the top of the printer queue.
+.Pp
+.It Ic up Brq Cm all | Ar printer
+Enable everything and start a new printer daemon.
+Undoes the effects of
+.Ic down .

+.Sh NAME
+.Nm lpd
+.Nd line printer spooler daemon
+.Sh SYNOPSIS
+.Nm
+.Op Fl cdlpsW46
+.Op Ar port#
+.Sh DESCRIPTION
+.Nm Lpd
+is the line printer daemon (spool area handler) and is normally invoked
+at boot time from the
+.Xr rc 8
+file.  It makes a single pass through the
+.Xr printcap 5
+file to find out about the existing printers and
+prints any files left after a crash.
+It then uses the system calls
+.Xr listen 2
+and
+.Xr accept 2
+to receive requests to print files in the queue,
+transfer files to the spooling area, display the queue,
+or remove jobs from the queue.  In each case, it forks a child to handle
+the request so the parent can continue to listen for more requests.
+.Pp
+Available options:
+.Bl -tag -width Ds
+.It Fl c
+By default, if some remote host has a connection error while trying to
+send a print request to
+.Nm
+on a local host,
+.Nm
+will only send error message to that remote host.
+The
+.Fl c
+flag causes
+.Nm
+to also log all of those connection errors via
+.Xr syslog 3 .
+.It Fl d
+Turn on
+.Dv SO_DEBUG
+on the Internet listening socket (see
+.Xr setsockopt 2 ) .
+.It Fl l
+The
+.Fl l
+flag causes
+.Nm
+to log valid requests received from the network.
+This can be useful
+for debugging purposes.
+.It Fl p
+The
+.Fl p
+flag is a synonym for the
+.Fl s
+flag.
+It is being depreciated, and may be removed in a
+future version of
+.Nm .
+.It Fl s
+The
+.Fl s
+(secure) flag causes
+.Nm
+not to open an Internet listening socket.
+This means that
+.Nm
+will not accept any connections from any remote
+hosts, although it will still accept print requests
+from all local users.
+.It Fl W
+By default, the
+.Nm
+daemon will only accept connections which originate
+from a reserved-port (<1024) on the remote host.
+The
+.Fl W
+flag causes
+.Nm
+to accept connections coming from any port.
+This is can be useful when you want to accept print jobs
+from certain implementations of lpr written for Windows.
+.It Fl 4
+Inet only.
+.It Fl 6
+Inet6 only.
+.It Fl 46
+Inet and inet6 (default).
+.It Ar "port#"
+The Internet port number used to rendezvous
+with other processes is normally obtained with
+.Xr getservbyname 3
+but can be changed with the
+.Ar port#
+argument.
+.El
+.Pp
+Access control is provided by two means.
+First, all requests must come from
+one of the machines listed in the file
+.Pa /etc/hosts.equiv
+or
+.Pa /etc/hosts.lpd .
+Second, if the
+.Li rs
+capability is specified in the
+.Xr printcap 5
+entry for the printer being accessed,
+.Em lpr
+requests will only be honored for those users with accounts on the
+machine with the printer.
+.Pp
+The file
+.Em minfree
+in each spool directory contains the number of disk blocks to leave free
+so that the line printer queue won't completely fill the disk.
+The
+.Em minfree
+file can be edited with your favorite text editor.
+.Pp
+The daemon begins processing files
+after it has successfully set the lock for exclusive
+access (described a bit later),
+and scans the spool directory
+for files beginning with
+.Em cf .
+Lines in each
+.Em cf
+file specify files to be printed or non-printing actions to be
+performed.  Each such line begins with a key character
+to specify what to do with the remainder of the line.
+.Bl -tag -width Ds
+.It J
+Job Name.  String to be used for the job name on the burst page.
+.It C
+Classification.  String to be used for the classification line
+on the burst page.
+.It L
+Literal.  The line contains identification info from
+the password file and causes the banner page to be printed.
+.It T
+Title.  String to be used as the title for
+.Xr pr 1 .
+.It H
+Host Name.  Name of the machine where
+.Xr lpr
+was invoked.
+.It P
+Person.  Login name of the person who invoked
+.Xr lpr .
+This is used to verify ownership by
+.Xr lprm .
+.It M
+Send mail to the specified user when the current print job completes.
+.It f
+Formatted File.  Name of a file to print which is already formatted.
+.It l
+Like ``f'' but passes control characters and does not make page breaks.
+.It p
+Name of a file to print using
+.Xr pr 1
+as a filter.
+.It t
+Troff File.  The file contains
+.Xr troff 1
+output (cat phototypesetter commands).
+.It n
+Ditroff File.  The file contains device independent troff
+output.
+.It r
+DVI File.  The file contains
+.Tn Tex l
+output
+DVI format from Standford.
+.It g
+Graph File.  The file contains data produced by
+.Xr plot 3 .
+.It c
+Cifplot File.
+The file contains data produced by
+.Em cifplot .
+.It v
+The file contains a raster image.
+.It r
+The file contains text data with
+FORTRAN carriage control characters.
+.It \&1
+Troff Font R. Name of the font file to use instead of the default.
+.It \&2
+Troff Font I. Name of the font file to use instead of the default.
+.It \&3
+Troff Font B. Name of the font file to use instead of the default.
+.It \&4
+Troff Font S. Name of the font file to use instead of the default.
+.It W
+Width.
+Changes the page width (in characters) used by
+.Xr pr 1
+and the text filters.
+.It I
+Indent.  The number of characters to indent the output by (in ASCII).
+.It U
+Unlink.  Name of file to remove upon completion of printing.
+.It N
+File name.  The name of the file which is being printed, or a blank
+for the standard input (when
+.Xr lpr
+is invoked in a pipeline).
+.It Z
+Locale.  String to be used as the locale for
+.Xr pr 1 .
+.El
+.Pp
+If a file cannot be opened, a message will be logged via
+.Xr syslog 3
+using the
+.Em LOG_LPR
+facility.
+.Nm Lpd
+will try up to 20 times
+to reopen a file it expects to be there, after which it will
+skip the file to be printed.
+.Pp
+.Nm Lpd
+uses
+.Xr flock 2
+to provide exclusive access to the lock file and to prevent multiple
+daemons from becoming active simultaneously.  If the daemon should be killed
+or die unexpectedly, the lock file need not be removed.
+The lock file is kept in a readable
+.Tn ASCII
+form
+and contains two lines.
+The first is the process id of the daemon and the second is the control
+file name of the current job being printed.  The second line is updated to
+reflect the current status of
+.Nm
+for the programs
+.Xr lpq 1
+and
+.Xr lprm 1 .

+ * Strategy to maintain protected spooling area:
+ *	1. Spooling area is writable only by daemon and spooling group
+ *	2. lpr runs setuid root and setgrp spooling group; it uses
+ *	   root to access any file it wants (verifying things before
+ *	   with an access call) and group id to know how it should
+ *	   set up ownership of files in the spooling area.
+ *	3. Files in spooling area are owned by root, group spooling
+ *	   group, with mode 660.
+ *	4. lpd, lpq and lprm run setuid daemon and setgrp spooling group to
+ *	   access files and printer.  Users can't get to anything
+ *	   w/o help of lpq and lprm programs.

+.Nd spool queue examination program
+.Sh SYNOPSIS
+.Nm
+.Op Fl a
+.Op Fl l
+.Op Fl P Ns Ar printer
+.Op  job # ...\&
+.Op  user ...\&
+.Sh DESCRIPTION
+The
+.Nm
+utility examines the spooling area used by
+.Xr lpd  8
+for printing files on the line printer, and reports the status of the
+specified jobs or all jobs associated with a user.
+The
+.Nm
+utility invoked
+without any arguments reports on any jobs currently in the queue.
+.Pp
+Options:
+.Pp
+.Bl -tag -width indent
+.It Fl P
+Specify a particular printer, otherwise the default
+line printer is used (or the value of the
+.Ev PRINTER
+variable in the
+environment). All other arguments supplied are interpreted as user
+names or job numbers to filter out only those jobs of interest.
+.It Fl l
+Information about each of the files comprising the job entry
+is printed.
+Normally, only as much information as will fit on one line is displayed.
+.It Fl a
+Report on the local queues for all printers,
+rather than just the specified printer.
+.El
+.Pp
+For each job submitted (i.e. invocation of
+.Xr lpr  1  )
+.Nm
+reports the user's name, current rank in the queue, the
+names of files comprising the job, the job identifier (a number which
+may be supplied to
+.Xr lprm  1
+for removing a specific job), and the total size in bytes.
+Job ordering is dependent on
+the algorithm used to scan the spooling directory and is supposed
+to be
+.Tn FIFO
+(First in First Out).
+File names comprising a job may be unavailable
+(when
+.Xr lpr  1
+is used as a sink in a pipeline) in which case the file
+is indicated as ``(standard input)''.
+.Pp
+If
+.Nm
+warns that there is no daemon present (i.e. due to some malfunction),
+the
+.Xr lpc  8
+command can be used to restart the printer daemon.
+.Sh ENVIRONMENT
+If the following environment variable exists, it is used by
+.Nm :
+.Bl -tag -width PRINTER
+.It Ev PRINTER
+Specifies an alternate default printer.
+.El
+.Sh FILES
+.Bl -tag -width "/var/spool/*/lock" -compact
+.It Pa /etc/printcap
+To determine printer characteristics.
+.It Pa /var/spool/*
+The spooling directory, as determined from printcap.
+.It Pa /var/spool/*/cf*
+Control files specifying jobs.
+.It Pa /var/spool/*/lock
+The lock file to obtain the currently active job.
+.El
+.Sh SEE ALSO
+.Xr lpr 1 ,
+.Xr lprm 1 ,
+.Xr lpc 8 ,
+.Xr lpd 8
+.Sh HISTORY
+A
+.Nm
+utility appeared in
+.Bx 3 .
+.Sh BUGS
+Due to the dynamic nature of the information in the spooling directory
+.Nm
+may report unreliably.
+Output formatting is sensitive to the line length of the terminal;
+this can results in widely spaced columns.
+.Sh DIAGNOSTICS
+Unable to open various files.  The lock file being malformed.  Garbage
+files when there is no daemon active, but files in the spooling directory.

+.Sh DESCRIPTION
+The
+.Nm
+utility uses a spooling daemon to print the named files when facilities
+become available.  If no names appear, the standard input is assumed.
+.Pp
+The following single letter options are used to notify the line printer
+spooler that the files are not standard text files.
+The spooling daemon will
+use the appropriate filters to print the data accordingly.
+Note that not all spoolers implement filters for all data types,
+and some sites may use these types for other purposes than the ones
+described here.
+.Bl -tag -width indent
+.It Fl d
+The files are assumed to contain data in
+.Tn DVI
+format from the
+.Tn TeX
+typesetting system.
+.It Fl f
+Use a filter which interprets the first character of each line as a
+standard
+.Tn FORTRAN
+carriage control character.
+.It Fl l
+Use a filter which allows control characters to be printed and suppresses
+page breaks.
+.It Fl p
+Use
+.Xr pr 1
+to format the files.
+.El
+.Pp
+The following options are historical and not directly supported by any
+software included in
+.Fx .
+.Bl -tag -width indent
+.It Fl c
+The files are assumed to contain data produced by
+.Xr cifplot 1 .
+.It Fl g
+The files are assumed to contain standard plot data as produced by the
+.Ux
+.Xr plot 3
+routines.
+.It Fl n
+The files are assumed to contain data from
+.Em ditroff
+(device independent troff).
+.It Fl t
+The files are assumed to contain
+.Tn C/A/T
+phototypesetter commands from ancient versions of
+.Ux
+.Xr troff 1 .
+.It Fl v
+The files are assumed to contain a raster image for devices like the
+Benson Varian.
+.El
+.Pp
+These options apply to the handling of
+the print job:
+.Bl -tag -width indent
+.It Fl P
+Force output to a specific printer.  Normally,
+the default printer is used (site dependent), or the value of the
+environment variable
+.Ev PRINTER
+is used.
+.It Fl h
+Suppress the printing of the burst page.
+.It Fl m
+Send mail upon completion.
+.It Fl r
+Remove the file upon completion of spooling or upon completion of
+printing (with the
+.Fl s
+option).
+.It Fl s
+Use symbolic links.  Usually files are copied to the spool directory.
+The
+.Fl s
+option will use
+.Xr symlink  2
+to link data files rather than trying to copy them so large files can be
+printed.  This means the files should
+not be modified or removed until they have been printed.
+.El
+.Pp
+The remaining options apply to copies, the page display, and headers:
+.Bl -tag -width indent
+.It Fl \&# Ns Ar num
+The quantity
+.Ar num
+is the number of copies desired of each file named.  For example,
+.Bd -literal -offset indent
+lpr \-#3 foo.c bar.c more.c
+.Ed
+would result in 3 copies of the file foo.c, followed by 3 copies
+of the file bar.c, etc.  On the other hand,
+.Bd -literal -offset indent
+cat foo.c bar.c more.c \&| lpr \-#3
+.Ed
+.Pp
+will give three copies of the concatenation of the files.
+Often
+a site will disable this feature to encourage use of a photocopier
+instead.
+.It Xo
+.Fl Ns Op Cm 1234
+.Ar font
+.Xc
+Specifies a
+.Ar font
+to be mounted on font position
+.Ar i  .
+The daemon
+will construct a
+.Li .railmag
+file referencing
+the font pathname.
+.It Fl C Ar class
+Job classification
+to use on the burst page.  For example,
+.Bd -literal -offset indent
+lpr \-C EECS foo.c
+.Ed
+.Pp
+causes the system name (the name returned by
+.Xr hostname  1  )
+to be replaced on the burst page by
+.Tn EECS ,
+and the file foo.c to be printed.
+.It Fl J Ar job
+Job name to print on the burst page.
+Normally, the first file's name is used.
+.It Fl L Ar locale
+Use
+.Ar locale
+specified as argument instead of one found in environment.
+(Only effective when filtering through
+.Xr pr 1
+is requested using the
+.Fl p
+option.)
+.It Fl T Ar title
+Title name for
+.Xr pr 1 ,
+instead of the file name.
+.It Fl U Ar user
+User name to print on the burst page,
+also for accounting purposes.
+This option is only honored if the real user-id is daemon
+(or that specified in the printcap file instead of daemon),
+and is intended for those instances where print filters wish to requeue jobs.
+.It Fl Z Ar daemon-options
+Some spoolers, such as
+.Tn LPRng ,
+accept additional per-job options using a
+.Ql Z
+control line.
+When
+.Fl Z
+is specified, and
+.Fl p
+.Pq Xr pr 1
+is not requested, the specified
+.Ar daemon-options
+will be passed to the remote
+.Tn LPRng
+spooler.
+.It Fl i Ar numcols
+The output is indented by
+.Pq Ar numcols .
+.It Fl w Ar num
+Uses
+.Ar num
+as the page width for
+.Xr pr 1 .

+If you try to spool too large a file, it will be truncated.
+The
+.Nm
+utility will object to printing binary files.
+If a user other than root prints a file and spooling is disabled,
+.Nm
+will print a message saying so and will not put jobs in the queue.
+If a connection to
+.Xr lpd 8
+on the local machine cannot be made,
+.Nm
+will say that the daemon cannot be started.
+Diagnostics may be printed in the daemon's log file
+regarding missing spool files by
+.Xr lpd 8 .
+.Sh BUGS
+Fonts for
+.Xr troff 1
+and
+.Tn TeX
+reside on the host with the printer.
+It is currently not possible to
+use local font libraries.
+.Pp
+The
+.Ql Z
+control file line is used for two different purposes; for
+standard
+.Fx
+.Xr lpd 8 ,
+it specifies a locale to be passed to
+.Xr pr 1 .
+For
+.Tn LPRng
+.Xr lpd 8 ,
+it specifies additional options to be interpreted by the spooler's
+input and output filters.
+When submitting jobs via
+.Nm ,
+.Fl p
+.Fl L Ar locale
+is used in the former context, and
+.Fl Z Ar daemon-options
+is used in the latter.

+.Sh NAME
+.Nm printcap
+.Nd printer capability data base
+.Sh SYNOPSIS
+.Nm
+.Sh DESCRIPTION
+The
+.Nm Printcap
+function
+is a simplified version of the
+.Xr termcap 5
+data base
+used to describe line printers.  The spooling system accesses the
+.Nm
+file every time it is used, allowing dynamic
+addition and deletion of printers.  Each entry in the data base
+is used to describe one printer.  This data base may not be
+substituted for, as is possible for
+.Xr termcap 5 ,
+because it may allow accounting to be bypassed.
+.Pp
+The default printer is normally
+.Em lp ,
+though the environment variable
+.Ev PRINTER
+may be used to override this.  Each spooling utility supports an option,
+.Fl P Ar printer ,
+to allow explicit naming of a destination printer.
+.Pp
+Refer to the
+.%T "4.3 BSD Line Printer Spooler Manual"
+for a complete discussion on how to setup the database for a given printer.
+.Sh CAPABILITIES
+Refer to
+.Xr termcap 5
+for a description of the file layout.

+.Sh FILTERS
+The
+.Xr lpd 8
+daemon creates a pipeline of
+.Em filters
+to process files for various printer types.
+The filters selected depend on the flags passed to
+.Xr lpr 1 .
+The pipeline set up is:
+.Bd -literal -offset indent
+p	pr | if	regular text + pr(1)
+none	if	regular text
+c	cf	cifplot
+d	df	DVI (tex)
+g	gf	plot(3)
+n	nf	ditroff
+f	rf	Fortran
+t	tf	troff
+v	vf	raster image
+.Ed
+.Pp
+The
+.Sy if
+filter is invoked with arguments:
+.Bd -ragged -offset indent
+.Cm if
+.Op Fl c
+.Fl w Ns Ar width
+.Fl l Ns Ar length
+.Fl i Ns Ar indent
+.Fl n Ar login
+.Fl h Ar host acct-file
+.Ed
+.Pp
+The
+.Fl c
+flag is passed only if the
+.Fl l
+flag (pass control characters literally)
+is specified to
+.Xr lpr 1 .
+The
+.Ar Width
+function
+and
+.Ar length
+specify the page width and length
+(from
+.Cm pw
+and
+.Cm pl
+respectively) in characters.
+The
+.Fl n
+and
+.Fl h
+parameters specify the login name and host name of the owner
+of the job respectively.
+The
+.Ar Acct-file
+function
+is passed from the
+.Cm af
+.Nm
+entry.
+.Pp
+If no
+.Cm if
+is specified,
+.Cm of
+is used instead,
+with the distinction that
+.Cm of
+is opened only once,
+while
+.Cm if
+is opened for every individual job.
+Thus,
+.Cm if
+is better suited to performing accounting.
+The
+.Cm of
+is only given the
+.Ar width
+and
+.Ar length
+flags.
+.Pp
+All other filters are called as:
+.Bd -ragged -offset indent
+.Nm filter
+.Fl x Ns Ar width
+.Fl y Ns Ar length
+.Fl n Ar login
+.Fl h Ar host acct-file
+.Ed
+.Pp
+where
+.Ar width
+and
+.Ar length
+are represented in pixels,
+specified by the
+.Cm px
+and
+.Cm py
+entries respectively.
+.Pp
+All filters take
+.Em stdin
+as the file,
+.Em stdout
+as the printer,
+may log either to
+.Em stderr
+or using
+.Xr syslog 3 ,
+and must not ignore
+.Dv SIGINT .
+.Sh REMOTE PRINTING
+When printing to a remote printer using
+.Cm rm ,
+it is possible to use either
+.Cm if
+or
+.Cm of .
+If both are specified,
+.Cm of
+is ignored.  Both filters behave the same except that they are passed
+different arguments as above.  Specifically, the output filter is
+terminated and restarted for each file transmitted.  This is necessary
+in order to pass the resulting size to the remote
+.Xr lpd 8 .
+.Pp
+If the
+.Fl p
+flag was passed to
+.Xr lpr 1 ,
+.Xr pr 1
+is not executed locally, but is requested of the remote
+.Xr lpd 8 .
+Any input filtering via
+.Cm if
+will therefore happen before
+.Xr pr 1
+is executed rather than afterwards.
+.Pp
+There are some models of network printers which accept jobs from
+.Xr lpd 8 ,
+but they ignore the control file for a job and simply print
+each data file as it arrives at the printer.
+One side-effect of this behavior is that the printer will ignore any request
+for multiple copies as given with the
+.Fl #
+flag on the
+.Xr lpr 1
+command.
+The
+.Cm rc
+entry will cause
+.Xr lpd 8
+to resend each data file for each copy that the user
+originally requested.
+Note that the
+.Cm rc
+entry should only be specified on hosts which send jobs directly to
+the printer.
+.Pp
+If
+.Cm lp
+is specified as
+.Em port Ns No @ Ns Em machine
+(and
+.Cm rm
+is not in use), printing will be send directly to the given
+.Em port
+on the given
+.Em machine .
+.Sh TRANSFER STATISTICS
+When a print job is transfered to a remote machine (which might be
+another unix box, or may be a network printer), it may be useful
+to keep statistics on each transfer.  The
+.Cm sr
+and
+.Cm ss
+options indicate filenames that lpd should use to store such
+statistics.  A statistics line is written for each datafile of a
+job as the file is successfully transferred.  The format of the
+line is the same for both the sending and receiving side of a
+transfer.
+.Pp
+Statistics on datafiles being received would be used on a print
+server, if you are interested in network performance between a
+variety of machines which are sending jobs to that print server.
+The print server could collect statistics on the speed of each
+print job as it arrived on the server.
+.Pp
+Statistics on datafiles being sent might be used as a minimal
+accounting record, when you want to know who sent which jobs to a
+remote printer, when they were sent, and how large (in bytes) the
+files were.  This will not give include any idea of how many pages
+were printed, because there is no standard way to get that information
+back from a remote (network) printer in this case.
+.Sh LOGGING
+Error messages generated by the line printer programs themselves
+(that is, the
+.Xr lpd 8
+and related programs)
+are logged by
+.Xr syslog 3
+using the
+.Dv LPR
+facility.
+Messages printed on
+.Em stderr
+of one of the filters
+are sent to the corresponding
+.Cm lf
+file.
+The filters may, of course, use
+.Xr syslogd 8
+themselves.
+.Pp
+Error messages sent to the console have a carriage return and a line
+feed appended to them, rather than just a line feed.

+.Nd remove jobs from the line printer spooling queue
+.Sh SYNOPSIS
+.Nm
+.Op Fl P Ns Ar printer
+.Op Fl
+.Op job # ...\&
+.Op Ar user ...\&
+.Sh DESCRIPTION
+The
+.Nm
+utility will remove a job, or jobs, from a printer's spool queue.
+Since the spooling directory is protected from users, using
+.Nm
+is normally the only method by which a user may remove a job.
+The owner of a job is determined by the user's login name
+and host name on the machine where the
+.Xr lpr 1
+command was invoked.
+.Pp
+Options and arguments:
+.Bl -tag -width indent
+.It Fl P Ns Ar printer
+Specify the queue associated with a specific
+.Ar printer
+(otherwise the default printer is used).
+.It Fl
+If a single
+.Sq Fl
+is given,
+.Nm
+will remove all jobs which a user
+owns.  If the super-user employs this flag, the spool queue will
+be emptied entirely.
+.It Ar user
+Cause

+.Nd generate lineprinter ripple pattern
+.Sh SYNOPSIS
+.Nm
+.Op Ar length
+.Op Ar count
+.Sh DESCRIPTION
+The
+.Nm
+utility writes the traditional "ripple test" pattern on standard output.
+In 96 lines,
+this pattern will print all 96 printable
+.Tn ASCII
+characters
+in each position.
+While originally created to test printers, it is quite
+useful for testing terminals,
+driving terminal ports for debugging purposes,
+or any other task where a quick supply of random data is needed.
+.Pp
+The
+.Ar length
+argument specifies the output line length if the default
+length of 79 is inappropriate.
+.Pp
+The
+.Ar count
+argument specifies the number of output lines to be generated if
+the default count of 200 is inappropriate.
+Note that if
+.Ar count
+is to be specified,
+.Ar length
+must be also be specified.

+.Op Fl p Ns Ar price
+.Op Fl s
+.Op Fl r
+.Op Ar name ...
+.Sh DESCRIPTION
+.Nm Pac
+reads the printer/plotter accounting files, accumulating the number
+of pages (the usual case) or feet (for raster devices)
+of paper consumed by each user, and printing out
+how much each user consumed in pages or feet and dollars.
+.Pp
+Options and operands available:
+.Bl -tag -width PPprinter
+.It Fl P Ns Ar printer
+Accounting is done for the named printer.
+Normally, accounting is done for the default printer (site dependent) or
+the value of the environment variable
+.Ev PRINTER
+is used.
+.It Fl c
+Cause the output to be sorted by cost; usually the
+output is sorted alphabetically by name.
+.It Fl m
+Cause the host name to be ignored in the accounting file.  This
+allows for a user on multiple machines to have all of his printing
+charges grouped together.
+.It Fl p Ns Ar price
+The value
+.Ar price
+is used for the cost in dollars instead of the default value of 0.02
+or the price specified in
+.Pa /etc/printcap .
+.It Fl r
+Reverse the sorting order.
+.It Fl s
+Accounting information is summarized on the
+summary accounting file; this summarization is necessary since on a
+busy system, the accounting file can grow by several lines per day.
+.It Ar names
+Statistics are only printed for user(s)
+.Ar name ;
+usually, statistics are printed for every user who has used any paper.

+.Op Fl d Ar device
+.Sh DESCRIPTION
+The
+.Nm
+command is used to set either the interrupt-driven, extended or polling mode
+of individual
+.Xr lpt 4
+devices.
+When a printer is switched from
+a mode to another, this change will only take effect
+the next time the device is opened.
+.Pp
+Extended mode is anything the parallel port interface can support.
+For an
+ECP/ISA parallel port, it may be FIFO+DMA or ECP.
+.Pp
+The following command line options are supported:
+.Bl -tag -width indent
+.It Fl i
+Turn on interrupt-driven mode.
+.It Fl p
+Turn on polled mode.
+.It Fl e
+Turn on extended mode.
+.It Fl s
+Turn on standard mode, i.e. turn off extended mode.
+.It Fl d Ar device
+Set the mode of the printer device specified by
+.Ar device .
+The default value for
+.Ar device
+is
+.Pa /dev/lpt0 .
+.El
+.Pp
+One of
+.Fl i , p
+or
+.Fl e
+must be specified.

+.Dt MAILWRAPPER 8
+.Os
+.Sh NAME
+.Nm mailwrapper
+.Nd invoke appropriate MTA software based on configuration file
+.Sh SYNOPSIS
+Special.
+See below.
+.Sh DESCRIPTION
+At one time, the only Mail Transfer Agent (MTA) software easily available
+was
+.Xr sendmail 8 .
+As a result of this, most Mail User Agents (MUAs) such as
+.Xr mail 1
+had the path and calling conventions expected by
+.Xr sendmail 8
+compiled in.
+.Pp
+Times have changed, however.
+On a modern
+.Ux
+system, the administrator may wish to use one of several
+available MTAs.
+.Pp
+It would be difficult to modify all MUA software typically available
+on a system, so most of the authors of alternative MTAs have written
+their front end message submission programs so that they use the same
+calling conventions as
+.Xr sendmail 8
+and may be put into place instead of
+.Xr sendmail 8
+in
+.Pa /usr/sbin/sendmail .
+.Pp
+.Xr sendmail 8
+also typically has aliases named
+.Xr mailq 1
+and
+.Xr newaliases 1
+linked to it.
+The program knows to behave differently when its
+.Va argv[0]
+is
+.Dq mailq
+or
+.Dq newaliases
+and behaves appropriately.
+Typically, replacement MTAs provide similar
+functionality, either through a program that also switches behavior
+based on calling name, or through a set of programs that provide
+similar functionality.
+.Pp
+Although having replacement programs that plug replace
+.Xr sendmail 8
+helps in installing alternative MTAs, it essentially makes the
+configuration of the system depend on hard installing new programs in
+.Pa /usr .
+This leads to configuration problems for many administrators, since
+they may wish to install a new MTA without altering the system
+provided
+.Pa /usr .
+(This may be, for example, to avoid having upgrade problems when a new
+version of the system is installed over the old.)
+They may also have a shared
+.Pa /usr
+among several
+machines, and may wish to avoid placing implicit configuration
+information in a read-only
+.Pa /usr .
+.Pp
+The
+.Nm
+program is designed to replace
+.Pa /usr/sbin/sendmail
+and to invoke an appropriate MTA instead of
+.Xr sendmail 8
+based on configuration information placed in
+.Pa /etc/mail/mailer.conf .
+This permits the administrator to configure which MTA is to be invoked on
+the system at run time.
+.Sh FILES
+Configuration for
+.Nm
+is kept in
+.Pa /etc/mail/mailer.conf .
+.Pa /usr/sbin/sendmail
+is typically set up as a symbolic link to
+.Nm
+which is not usually invoked on its own.
+.Sh DIAGNOSTICS
+.Nm
+will return an error value and print a diagnostic if its configuration
+file is missing or malformed, or does not contain a mapping for the
+name under which
+.Nm
+was invoked.
+.Sh SEE ALSO
+.Xr mail 1 ,
+.Xr mailq 1 ,
+.Xr newaliases 1 ,
+.Xr mailer.conf 5 ,
+.Xr sendmail 8
+.Sh HISTORY
+.Nm
+first appeared in
+.Nx 1.4
+and then
+.Fx 4.0 .
+.Sh AUTHORS
+Perry E. Metzger <perry@piermont.com>
+.Sh BUGS
+The entire reason this program exists is a crock.
+Instead, a command
+for how to submit mail should be standardized, and all the "behave
+differently if invoked with a different name" behavior of things like
+.Xr mailq 1
+should go away.

+.Sh DESCRIPTION
+A number of supported system architectures allow the behaviour of the CPU
+cache to be programmed to behave differently depending on the region being
+written.
+.Pp
+.Nm Memcontrol
+provides an interface to this facility, allowing CPU cache behavior to
+be altered for ranges of system physical memory.
+.Pp
+These ranges are typically power-of-2 aligned and sized, however the specific
+rules governing their layout vary between architectures.  The
+.Nm
+program does not attempt to enforce these rules, however the system will
+reject any attempt to set an illegal combination.
+.Bl -tag -width clear
+.It Ar list
+List range slots.
+.Bl -tag -width xxxxxx
+.It Op Fl a
+List all range slots, even those that are inactive
+.El
+.It Ar set
+Set memory range attributes.
+.Bl -tag -width xxxxxx
+.It Fl b Ar base
+Memory range base address
+.It Fl l Ar length
+Length of memory range in bytes, power of 2
+.It Fl o Ar owner
+Text identifier for this setting (7 char max)
+.It Ar attribute
+Attributes applied to this range; one of
+.Ar uncacheable ,
+.Ar write-combine ,
+.Ar write-through ,
+.Ar write-back ,
+.Ar write-protect
+.El
+.It Ar clear
+Clear memory range attributes.
+Ranges may be cleared by owner or by
+base/length combination.
+.Pp
+To clear based on ownership:
+.Bl -tag -width xxxxxx
+.It Fl o Ar owner
+All ranges with this owner will be cleared
+.El
+.Pp
+To clear based on the base/length combination:
+.Bl -tag -width xxxxxx
+.It Fl b Ar base
+Memory range base address
+.It Fl l Ar length
+Length of memory range in bytes, power of 2
+.El
+.Pp
+Base and length must exactly match an existing range.

+.Os
+.Sh NAME
+.Nm mergemaster
+.Nd merge configuration files, et al during an upgrade
+.Sh SYNOPSIS
+.Nm
+.Op Fl scrvahipC
+.Op Fl m Ar /path/to/sources
+.Op Fl t Ar /path/to/temp/root
+.Op Fl d
+.Op Fl u Ar N
+.Op Fl w Ar N
+.Op Fl D Ar /path
+.Sh DESCRIPTION
+.Nm
+is a Bourne shell script which is designed to aid you
+in updating the various configuration and other files
+associated with
+.Fx .
+It is
+.Sy HIGHLY
+recommended that you back up your
+.Pa /etc
+directory before beginning this process.
+.Pp
+The script uses
+.Pa /usr/src/etc/Makefile
+to build a temporary root environment from
+.Pa /
+down, populating that environment with the various
+files.
+You can specify a different source directory
+with the
+.Op Fl m
+command line option, or specify the destination
+directory with the
+.Op Fl D
+option.
+It then compares each file in that environment
+to its installed counterpart.
+When the script finds a
+change in the new file, or there is no installed
+version of the new file it gives you four options to
+deal with it.
+You can install the new file as is,
+delete the new file, merge the old and new
+files (as appropriate) using
+.Xr sdiff 1
+or leave the file in the temporary root environment to
+merge by hand later.
+.Pp
+By default it creates the temporary root in
+.Pa /var/tmp/temproot
+and compares the
+.Xr cvs 1
+version $Id/$FreeBSD strings for files that have them, deleting
+the temporary file if the strings match.
+If there is
+no $Id string, or if the strings are different it
+compares the files themselves.
+You can
+also specify that the script ignore the $Id strings and
+compare every file.
+.Pp
+.Nm
+checks your umask and issues a warning for anything
+other than 022. While it is not mandatory to grant
+world read permissions for most configuration files, you
+may run into problems without them.
+If you choose a
+umask other than 022 and experience trouble later this
+could be the cause.
+.Pa /etc/master.passwd
+is treated as a special case.
+If you choose to install
+this file or a merged version of it the file permissions
+are always 600 (rw-------) for security reasons.
+After
+installing an updated version of this file you should
+probably run
+.Xr pwd_mkdb 8
+with the -p option to rebuild your password databases
+and recreate
+.Pa /etc/passwd .
+.Pp
+The script uses the owner and group id's
+that the files are created with by
+.Pa /usr/src/etc/Makefile ,
+and file permissions as specified by the umask.
+Unified diffs are used by default to display any
+differences unless you choose context diffs.
+.Pp
+.Nm
+will source scripts that you specify right before
+it starts the comparison, and after it's done running.
+The easiest way to handle this is to place the path
+to the script(s) in the appropriate variables in your
+.Pa .mergemasterrc
+file.
+The script sourced before comparison is named in
+.Ev MM_PRE_COMPARE_SCRIPT ,
+and the one sourced after the script is done is
+.Ev MM_EXIT_SCRIPT .
+This is the recommended way to specify local modifications,
+or files that you want to give special handling to.
+This includes files that you want to be deleted without
+being compared.
+Because the named scripts are sourced from within
+.Nm ,
+all of the script's variables are available for use in
+your custom script.
+You can also use
+.Pa /etc/mergemaster.rc
+which will be read before
+.Pa .mergemasterrc .
+Options specified on the command line are updated last,
+and therefore can override both files.
+.Pp
+The options are as follows:
+.Bl -tag -width Fl
+.It Fl s
+Perform a strict comparison, diff'ing every pair of files.
+This comparison is performed line by line,
+without regard to CVS $Id's.
+.It Fl c
+Use context diffs instead of unified diffs.
+.It Fl r
+Re-run
+.Nm
+on a previously cleaned directory, skipping the creation of
+the temporary root environment.
+This option is compatible
+with all other options.
+.It Fl v
+Be more verbose about the process.
+You should probably use
+this option the first time you run
+.Nm .
+This option also gives you a list of files that exist
+only in the installed version of
+.Pa /etc .
+.It Fl a
+Run automatically.
+This option will leave all the files that
+differ from the installed versions in the temporary directory
+to be dealt with by hand.
+If the
+.Pa temproot
+directory exists, it creates a new one in a previously
+non-existent directory.
+This option unsets the verbose flag,
+but is compatible with all other options.
+Setting -a makes
+-w superfluous.
+.It Fl h
+Display usage and help information.
+.It Fl i
+Automatically install any files that do not exist in the
+destination directory.
+.It Fl p
+Pre-buildworld mode.
+Compares only files known to be essential to the success of
+{build|install}world,
+including
+.Pa /etc/make.conf .
+.It Fl C
+After a standard
+.Nm
+run,
+compares your rc.conf[.local] options to the defaults.
+.It Fl m Ar /path/to/sources
+Specify the path to the directory where you want to do the
+.Xr make 1 .
+(In other words, where your sources are, but -s was already
+taken.)
+.It Fl t Ar /path/to/temp/root
+Create the temporary root environment in
+.Pa /path/to/temp/root
+instead of the default
+.Pa /var/tmp/temproot .
+.It Fl d
+Add the date and time to the name of the temporary
+root directory.
+If -t is specified, this option must
+follow it if you want the date added too.
+.It Fl u Ar N
+Specify a numeric umask.
+The default is 022.
+.It Fl w Ar N
+Supply an alternate screen width to the
+.Xr sdiff 1
+command in numbers of columns.
+The default is 80.
+.It Fl D Ar /path
+Specify the destination directory for the installed files.
+.El
+.Sh ENVIRONMENT
+The
+.Nm
+script uses the

+environment variable if set.
+Otherwise it uses
+.Xr more 1 .
+If
+.Ev PAGER
+specifies a program outside
+its
+limited
+.Ev PATH
+without specifying the full path,
+.Nm
+prompts you with options on how to proceed.
+The
+.Ev MM_PRE_COMPARE_SCRIPT
+and
+.Ev MM_EXIT_SCRIPT
+variables are used as described above.
+Other variables that are used by the script internally
+can be specified in
+.Pa .mergemasterrc
+as described in more detail below.
+.Sh EXAMPLES
+Typically all you will need to do is type
+.Nm
+at the prompt and the script will do all the work for you.
+.Pp
+To use context diff's and have
+.Nm
+explain more things as it goes along, use:
+.Pp
+.Dl # mergemaster -cv
+.Pp
+To specify that
+.Nm
+put the temporary root environment in
+.Pa /usr/tmp/root ,
+use:
+.Pp
+.Dl # mergemaster -t /usr/tmp/root
+.Pp
+To specify a 110 column screen with a strict
+comparison, use:
+.Pp
+.Dl # mergemaster -sw 110
+.Sh FILES
+.Bl -tag -width $HOME/.mergemasterrc -compact
+.It Pa /etc/mergemaster.rc
+.It Pa $HOME/.mergemasterrc
+.El
+.Pp
+.Nm
+will . (source) these files if they exist.
+Command line options
+will override rc file options.
+.Pa $HOME/.mergemasterrc
+overrides
+.Pa /etc/mergemaster.rc .
+Here is an example
+with all values commented out:
+.Pp
+.Bd -literal
+# These are options for mergemaster, with their default values listed
+# The following options have command line overrides
+#
+# Directory to install the temporary root environment into
+#TEMPROOT='/var/tmp/temproot'
+#
+# Strict comparison bypasses the CVS $Id tests and compares every file
+#STRICT=no
+#
+# Flag(s) to use for diff displayed when files differ
+#DIFF_FLAG='-u'
+#
+# Verbose mode includes more details and additional checks
+#VERBOSE=
+#
+# Automatically install files that do not exist on the system already
+#AUTO_INSTALL=
+#
+# Compare /etc/rc.conf[.local] to /etc/defaults/rc.conf
+#COMP_CONFS=yes
+#
+# Sourcedir is the directory to do the 'make' in (where the new files are)
+#SOURCEDIR='/usr/src/etc'
+#
+# The umask for mergemaster to compare the default file's modes to
+#NEW_UMASK=022
+#
+# Specify the destination directory for the installed files
+#DESTDIR=
+#
+# The following options have no command line overrides
+# For those who just cannot stand including the full path to PAGER
+#DONT_CHECK_PAGER=
+#
+# If you set 'yes' above, make sure to include the PATH to your pager
+#PATH=/bin:/usr/bin:/usr/sbin
+#
+# Don't compare the old and new motd files
+#IGNORE_MOTD=yes
+#
+# Specify the path to scripts to run before the comparison starts,

+.Pp
+Exit status is 1 if it fails for one of the following reasons:

+.Pa comproot
+on 13 March 1998. The idea for creating the

+.Sh DESCRIPTION
+The
+.Nm
+command is used to set and display soundcard mixer device levels.
+It may
+also be used to start and stop recording from the soundcard.  The list
+of mixer devices that may be modified are:
+.Pp
+.Bd -ragged -offset indent
+vol, bass, treble, synth, pcm, speaker, mic, cd, mix,
+pcm2, rec, igain, ogain, line1, line2, and line3.
+.Ed
+.Pp
+Not all mixer devices are available.
+.Pp
+When
+.Nm
+is run without any arguments, all supported devices are displayed
+along with current values.
+If the
+.Ar dev
+argument is specified, the value for the
+.Ar dev
+device will be displayed.
+.Pp
+To modify the mixer value
+.Ar dev ,
+the optional left and right channel settings of
+.Ar lvol Ns Op : Ns Ar rvol
+may be specified.  The
+.Ar lvol
+and
+.Ar rvol
+arguments may be from 0 - 100.  Omitting
+.Ar dev
+and including only the channel settings will change the main volume level.
+.Pp
+If the
+.Fl s
+flag is used, the current mixer values will be displayed in a format suitable
+for use as the command-line arguments to a future invocation of
+.Nm
+(as above).
+.Pp
+To change the recording device you use one of:
+.Bl -tag -width =rec -offset indent
+.It Cm ^rec
+toggles
+.Ar rdev
+of possible recording devices
+.It Cm +rec
+adds
+.Ar rdev
+to possible recording devices
+.It Cm -rec
+removes
+.Ar rdev
+from possible recording devices
+.It Cm =rec
+sets the recording device to
+.Ar rdev
+.El
+.Pp
+The above commands work on an internal mask.  After all the options
+have been parsed, it will set then read the mask from the sound card.
+This will let you see EXACTLY what the soundcard is using for the
+recording device(s).
+.Pp
+The option recsrc will display the current recording devices.
+.Pp
+The option
+.Fl f
+.Ar device
+will open
+.Ar device
+as the mixer device.

+.\"
+.Sh SYNOPSIS
+.Nm
+.Op Fl dr
+.Ar intface
+.Op Ar maddr
+.\"
+.Sh DESCRIPTION
+.Nm
+sends an IPv6 multicast listener discovery (MLD) query packet toward
+the specified multicast address,
+.Ar maddr ,
+toward interface
+.Ar intface .
+If you omit
+.Ar maddr ,
+linklocal all nodes multicast address(ff02::1) is used.
+.Pp
+After sending a query,
+.Nm
+waits for replies for at most 10 seconds.
+If a reply is returned,
+.Nm
+prints it with its type and then waits for another reply.
+.Pp
+This program is provided only for debugging.
+It is not necessary for normal use.
+.Pp
+With
+.Fl d ,
+.Nm
+will transmit MLD done packet instead of MLD query packet.
+With
+.Fl r ,
+similarly, MLD report packet will be transmitted.
+.Fl dr
+options are for debugging purposes only.
+.\"
+.Sh RETURN VALUES
+The program exits with 0 on success, non-zero on failures.
+.\"
+.\" .Sh SEE ALSO
+.\"
+.Sh HISTORY
+The
+.Nm
+command first appeared in WIDE/KAME IPv6 protocol stack kit.
+.Sh BUGS
+.Nm Mld6query
+does not take care of multicast addresses which have non link-local
+scope.

+.Sh DESCRIPTION
+The
+.Nm
+utility provides status monitoring and management functions
+for devices attached
+to the
+.Xr mlx 4
+driver.
+.Pp
+Controller names are of the form "mlxN"
+where N is the unit number of the controller.
+Drive names are of the form "mlxdN"
+where N is the unit number of the drive.
+Do not specify the path to a device node.
+.Pp
+.Bl -tag -width rebuild
+.It status
+Print the status of controllers and system drives.
+If one or more drives are specified,
+only print information about these drives,
+otherwise print information
+about all controllers and drives in the system.
+With the
+.Fl v
+flag, display much more verbose information.
+With the
+.Fl q
+flag, do not print any output.
+This command returns
+0 if all drives tested are online,
+1 if one or more drives are critical and
+2 if one or more are offline.
+.It rescan
+Rescan one or more controllers for non-attached system drives
+(eg. drives that have been
+detached or created subsequent to driver initialisation).
+If the
+.Fl a
+flag is supplied, rescan all controllers in the system.
+.It detach
+Detach one or more system drives.
+Drives must be unmounted
+and not opened by any other utility for this command to succeed.
+If the
+.Fl a
+flag is supplied, detach all system drives from the nominated controller.
+.It check
+Initiate a consistency check and repair pass on a redundant system drive
+(eg. RAID1 or RAID5).
+The controller will scan the system drive and repair any inconsistencies.
+This command returns immediately;
+use the
+.Ar status
+command to monitor the progress of the check.
+.It rebuild
+Requires two arguments,
+.Ar controller
+and
+.Ar physdrive
+as specified in the
+output of the
+.Ar status
+command.
+All system drives using space on the physical drive
+.Ar physdrive
+are rebuilt, reconstructing all data on the drive.
+Note that each controller can only perform one rebuild at a time.
+This command returns immediately; use the
+.Ar status
+command to monitor the progress of the rebuild.
+.It config
+Print the current configuration from the nominated controller.
+This command will be updated
+to allow addition/deletion of system drives from a configuration
+in a future release.
+.It help
+Print usage information for
+.Ar command .
+.El
+.Sh BUGS
+The
+.Ar config
+command does not yet support modifying system drive configuration.
+.Pp
+Error log extraction is not yet supported.

+.Nd mount NetWare volume from a NetWare file server
+.Sh SYNOPSIS
+.Nm
+.Op Fl Chv
+.Fl S Ar server
+.Fl U Ar user
+.Op Fl connection\ options
+.Fl V Ar volume
+.Op Fl M Ar mode
+.Op Fl c Ar case
+.Op Fl d Ar mode

+.Op Fl g Ar gid
+.Op Fl l Ar locale
+.Op Fl n Ar os2
+.Op Fl u Ar uid
+.Op Fl w Ar scheme
+.Ar node
+.Nm
+.Op Fl options
+.Ar /server:user/volume[/path]
+.Ar node
+.Sh DESCRIPTION
+The
+.Nm
+utility allows to mount volume from a NetWare server.
+It may use either
+existing connection or create new: if no usable connection was found
+it will try to establish a new one.
+Connection has count of references to it,
+so when last mount will be dismounted connection will be closed.
+It is
+possible to create connection without any mounts (but use it for them) with
+.Xr ncplogin 1 .
+.Pp
+Note two forms of command line.
+In the first form, server and user specified
+via
+.Fl S
+and
+.Fl U
+options respectively.
+In the second form server and user specified in
+.Ar special
+part of
+.Xr mount 8
+command line arguments (the
+.Fl S ,
+.Fl U
+and
+.Fl V
+options aren't used in this case).
+This allows use of
+.Xr fstab 5
+file (see
+.Sx EXAMPLES
+below).
+.Pp
+The options are:
+.Bl -tag -width indent
+.It Fl S Ar server
+Name of NetWare server to connect.
+For native IP you will need also
+.Fl A
+option.
+.It Fl U Ar user
+Name of user used in login sequence.
+.It Fl connection\ options
+See
+.Xr ncplogin 1
+for details.
+.It Fl V Ar volume
+Volume name to mount.
+Volume name can also be specified after all options and
+before
+.Ar mount-point .
+.It Ar node
+Path to mount volume.
+.It Fl c Ar case
+Select a
+.Ar case
+option which affects on name representation.
+.Ar Case
+can be one of the following:
+.Bl -tag -width "ValueXX"
+.It Em Value
+.Em Meaning
+.It l
+All existing file names converted to lower case.
+Newly created file gets a lower case under OS2 name space.
+This is the default when mounting volumes with DOS name space.
+.It L
+Same as 'l' but filesystem tries to be case insensitive.
+May not work well.
+.It n
+No case conversion is performed.
+.Em Warning !
+Use this option with DOS name space only as a last resort,
+because creating a lower case name in the DOS name space
+can lead to unpredictable results.
+This is the default when mounting volumes with OS2 name space.
+.It u
+All existing file names converted to upper case.
+Newly created file gets an upper case under OS2 name space.
+.It U
+Same as 'u' but filesystem tries to be case insensitive.
+May not work well.
+.El
+.It Fl f Ar mode , Fl d Ar mode
+Specify permissions that should be assigned to files and directories.
+The values must be specified as octal numbers.
+Default value for the file mode
+is taken from mount point, default value for the dir mode adds execute
+permission where the file mode gives read permission.
+.Pp
+Note that these permissions can differ from the rights granted by NetWare
+server.
+.It Fl n Ar namespace
+Don't use
+.Ar namespace .
+Currently only
+.Ar OS2
+can be here.
+.It Fl v
+Print version number.
+.It Fl u Ar uid , Fl g Ar gid
+User id and group id assigned to files.
+The default is owner and group id from
+directory where volume is mounted.
+.It Fl l Ar locale
+Set the locale for case conversion.
+By default
+.Nm
+tries to use an environment variable
+.Ev LC_* .
+.It Fl w Ar scheme
+Select a
+.Ar scheme
+used to convert file names between NetWare and
+.Fx .
+Supported conversion schemes are:
+.Bl -tag -width ".Cm koi2cp866"
+.It Cm asis
+Characters passed as is without any alteration.
+.It Cm koi2cp866
+koi8-r <-> CP866
+.It Cm se
+Suits for setups used in Sweden.
+.El
+.It Fl M Ar mode
+See
+.Xr ncplogin 1
+for details.
+If this option is omitted, connection permissions
+assumed the same as directory mode
+.Pq Fl d
+option.
+.El
+.Sh FILES
+.Bl -tag -width /var/log/wtmp -compact
+.It Pa ~/.nwfsrc
+keeps static parameters for connections and other information.
+See
+.Pa /usr/share/examples/nwclient/dot.nwfsrc
+for details.
+.El
+.Sh NOTES
+Before any NCP connection can be established kernel must be configured
+for IPX support, IPXrouted and KLD nwfs.ko should be loaded.
+.Sh EXAMPLES
+Next examples illustrates how to connect to NetWare server
+.Em nwserv
+as user
+.Em GUEST
+and mount volumes
+.Em SYS
+and
+.Em VOL1 :
+.Bd -literal -offset indent
+mount_nwfs -S nwserv -U guest -V sys /nw/s1/sys
+mount_nwfs /nwserv:guest/sys /nw/s1/sys
+mount -t nwfs /nwserv:guest/vol1 /nw/s1/vol1
+mount -t nwfs /nwserv:boris/sys/home/boris /home/boris/nw/home
+.Ed
+.Pp
+The last example mounts only subdirectory on a volume and equivalent
+to NetWare 'map root' command.
+.Pp
+It is possible to use
+.Xr fstab 5
+for nwfs mounts:
+.Bd -literal -offset indent
+/nwserv:guest/sys       /nw/s1/sys     nwfs  rw,noauto 0   0
+/nwserv:guest/vol1      /nw/s1/vol2    nwfs  rw,noauto 0   0
+.Ed
+.Sh HISTORY
+The
+.Nm
+utility first appeared in
+.Fx 4.0 .
+.Sh BUGS
+to number a few
+.Sh CREDITS
+In development of NetWare client for
+.Fx ,
+the following sources were used:

+.Os
+.Sh NAME
+.Nm mount_portalfs
+.Nd mount the portal daemon
+.Sh SYNOPSIS
+.Nm
+.Op Fl o Ar options
+.Ar /etc/portal.conf
+.Ar mount_point
+.Sh DESCRIPTION
+The
+.Nm
+utility attaches an instance of the portal daemon
+to the global filesystem namespace.
+The conventional mount point is
+.Pa /p .
+.\" .PA /dev .
+This command is normally executed by
+.Xr mount 8
+at boot time.
+.Pp
+The options are as follows:
+.Bl -tag -width indent
+.It Fl o
+Options are specified with a
+.Fl o
+flag followed by a comma separated string of options.
+See the
+.Xr mount 8
+man page for possible options and their meanings.
+.El
+.Pp
+The portal daemon provides an
+.Em open
+service.
+Objects opened under the portal mount point are
+dynamically created by the portal daemon according
+to rules specified in the named configuration file.
+Using this mechanism allows descriptors such as sockets
+to be made available in the filesystem namespace.
+.Pp
+The portal daemon works by being passed the full pathname
+of the object being opened.
+The daemon creates an appropriate descriptor according
+to the rules in the configuration file, and then passes the descriptor back
+to the calling process as the result of the open system call.
+.Sh NAMESPACE
+By convention, the portal daemon divides the namespace into sub-namespaces,
+each of which handles objects of a particular type.
+.Pp
+The following sub-namespaces are currently implemented:
+.Pa tcplisten ,
+.Pa tcp
+and
+.Pa fs .
+The
+.Pa tcplisten
+namespace takes a slash separated hostname and port and creates a TCP/IP
+socket bound to the given hostname-port pair.
+The hostname may be
+specified as "ANY" to allow any other host to connect to the socket.
+A
+port number of 0 will dynamically allocate a port, this can be
+discovered by calling
+.Xr getsockname 2
+with the returned file descriptor.
+Privileged ports can only be bound to
+by the super-user.
+The
+.Pa tcp
+namespace takes a hostname and a port (slash separated) and
+creates an open TCP/IP connection.
+The
+.Pa fs
+namespace opens the named file, starting back at the root directory.
+This can be used to provide a controlled escape path from
+a chrooted environment.
+.Sh "CONFIGURATION FILE"
+The configuration file contains a list of rules.
+Each rule takes one line and consists of two or more
+whitespace separated fields.
+A hash (``#'') character causes the remainder of a line to
+be ignored.  Blank lines are ignored.
+.Pp
+The first field is a pathname prefix to match
+against the requested pathname.
+If a match is found, the second field
+tells the daemon what type of object to create.
+Subsequent fields are passed to the creation function.

+.Os
+.Sh NAME
+.Nm exports
+.Nd define remote mount points for
+.Tn NFS
+mount requests
+.Sh SYNOPSIS
+.Nm
+.Sh DESCRIPTION
+The
+.Nm
+file specifies remote mount points for the
+.Tn NFS
+mount protocol per the
+.Tn NFS
+server specification; see
+.%T "Network File System Protocol Specification" ,
+RFC1094, Appendix A and
+.%T "NFS: Network File System Version 3 Specification" ,
+Appendix I.
+.Pp
+Each line in the file
+(other than comment lines that begin with a #)
+specifies the mount point(s) and export flags within one local server
+filesystem for one or more hosts.
+A long line may be split over several lines by ending all but the
+last line with a backslash
+.Pq Ql \e .
+A host may be specified only once for each local filesystem on the
+server and there may be only one default entry for each server
+filesystem that applies to all other hosts.
+The latter exports the filesystem to the ``world'' and should
+be used only when the filesystem contains public information.
+.Pp
+In a mount entry,
+the first field(s) specify the directory path(s) within a server filesystem
+that can be mounted on by the corresponding client(s).
+There are two forms of this specification.
+The first is to list all mount points as absolute
+directory paths separated by whitespace.
+The second is to specify the pathname of the root of the filesystem
+followed by the
+.Fl alldirs
+flag;
+this form allows the host(s) to mount at any point within the filesystem,
+including regular files if the
+.Fl r
+option is used on
+.Xr mountd 8 .
+The pathnames must not have any symbolic links in them and should not have
+any "." or ".." components.
+Mount points for a filesystem may appear on multiple lines each with
+different sets of hosts and export options.
+.Pp
+The second component of a line specifies how the filesystem is to be
+exported to the host set.
+The option flags specify whether the filesystem
+is exported read-only or read-write and how the client uid is mapped to
+user credentials on the server.
+.Pp
+Export options are specified as follows:
+.Pp
+.Sm off
+.Fl maproot No = Sy user
+.Sm on
+The credential of the specified user is used for remote access by root.
+The credential includes all the groups to which the user is a member
+on the local machine (see
+.Xr id 1 ) .
+The user may be specified by name or number.
+.Pp
+.Sm off
+.Fl maproot No = Sy user:group1:group2:...
+.Sm on
+The colon separated list is used to specify the precise credential
+to be used for remote access by root.
+The elements of the list may be either names or numbers.
+Note that user: should be used to distinguish a credential containing
+no groups from a complete credential for that user.
+.Pp
+.Sm off
+.Fl mapall No = Sy user
+.Sm on
+or
+.Sm off
+.Fl mapall No = Sy user:group1:group2:...
+.Sm on
+specifies a mapping for all client uids (including root)
+using the same semantics as
+.Fl maproot .
+.Pp
+The option
+.Fl r
+is a synonym for
+.Fl maproot
+in an effort to be backward compatible with older export file formats.
+.Pp
+In the absence of
+.Fl maproot
+and
+.Fl mapall
+options, remote accesses by root will result in using a credential of -2:-2.
+All other users will be mapped to their remote credential.
+If a
+.Fl maproot
+option is given,
+remote access by root will be mapped to that credential instead of -2:-2.
+If a
+.Fl mapall
+option is given,
+all users (including root) will be mapped to that credential in
+place of their own.
+.Pp
+The
+.Fl kerb
+option specifies that the Kerberos authentication server should be
+used to authenticate and map client credentials.
+This option requires that the kernel be built with the NFSKERB option.
+The use of this option will prevent the kernel from compiling
+unless calls to the appropriate Kerberos encryption routines
+are provided in the NFS source.
+.Pp
+The
+.Fl ro
+option specifies that the filesystem should be exported read-only
+(default read/write).
+The option
+.Fl o
+is a synonym for
+.Fl ro
+in an effort to be backward compatible with older export file formats.
+.Pp
+.Tn WebNFS
+exports strictly according to the spec (RFC 2054 and RFC 2055) can
+be done with the
+.Fl public
+flag.
+However, this flag in itself allows r/w access to all files in
+the filesystem, not requiring reserved ports and not remapping uids.
+It
+is only provided to conform to the spec, and should normally not be used.
+For a
+.Tn WebNFS
+export,
+use the
+.Fl webnfs
+flag, which implies
+.Fl public ,
+.Sm off
+.Fl mapall No = Sy nobody
+.Sm on
+and
+.Fl ro .
+.Pp
+A
+.Sm off
+.Fl index No = Sy file
+.Sm on
+option can be used to specify a file whose handle will be returned if
+a directory is looked up using the public filehandle
+.Pq Tn WebNFS .
+This is to mimic the behavior of URLs.
+If no
+.Fl index
+option is specified, a directory filehandle will be returned as usual.
+The
+.Fl index
+option only makes sense in combination with the
+.Fl public
+or
+.Fl webnfs
+flags.
+.Pp
+The third component of a line specifies the host set to which the line applies.
+The set may be specified in three ways.
+The first way is to list the host name(s) separated by white space.
+(Standard Internet ``dot'' addresses may be used in place of names.)
+The second way is to specify a ``netgroup'' as defined in the netgroup file (see
+.Xr netgroup 5 ) .
+The third way is to specify an Internet subnetwork using a network and
+network mask that is defined as the set of all hosts with addresses within
+the subnetwork.
+This latter approach requires less overhead within the
+kernel and is recommended for cases where the export line refers to a
+large number of clients within an administrative subnet.
+.Pp
+The first two cases are specified by simply listing the name(s) separated
+by whitespace.
+All names are checked to see if they are ``netgroup'' names
+first and are assumed to be hostnames otherwise.
+Using the full domain specification for a hostname can normally
+circumvent the problem of a host that has the same name as a netgroup.
+The third case is specified by the flag
+.Sm off
+.Fl network No = Sy netname
+.Sm on
+and optionally
+.Sm off
+.Fl mask No = Sy netmask .
+.Sm on
+If the mask is not specified, it will default to the mask for that network
+class (A, B or C; see
+.Xr inet 4 ) .
+.Pp
+For example:
+.Bd -literal -offset indent
+/usr /usr/local -maproot=0:10 friends
+/usr -maproot=daemon grumpy.cis.uoguelph.ca 131.104.48.16
+/usr -ro -mapall=nobody
+/u -maproot=bin: -network 131.104.48 -mask 255.255.255.0
+/u2 -maproot=root friends
+/u2 -alldirs -kerb -network cis-net -mask cis-mask
+.Ed
+.Pp
+Given that
+.Sy /usr ,
+.Sy /u
+and
+.Sy /u2
+are
+local filesystem mount points, the above example specifies the following:
+.Sy /usr
+is exported to hosts
+.Em friends
+where friends is specified in the netgroup file
+with users mapped to their remote credentials and
+root mapped to uid 0 and group 10.
+It is exported read-write and the hosts in ``friends'' can mount either /usr
+or /usr/local.
+It is exported to
+.Em 131.104.48.16
+and
+.Em grumpy.cis.uoguelph.ca
+with users mapped to their remote credentials and
+root mapped to the user and groups associated with ``daemon'';
+it is exported to the rest of the world as read-only with
+all users mapped to the user and groups associated with ``nobody''.
+.Pp
+.Sy /u
+is exported to all hosts on the subnetwork
+.Em 131.104.48
+with root mapped to the uid for ``bin'' and with no group access.
+.Pp
+.Sy /u2
+is exported to the hosts in ``friends'' with root mapped to uid and groups
+associated with ``root'';
+it is exported to all hosts on network ``cis-net'' allowing mounts at any
+directory within /u2 and mapping all uids to credentials for the principal
+that is authenticated by a Kerberos ticket.
+.Pp
+The
+.Xr mountd 8
+utility can be made to re-read the
+.Nm
+file by sending it a hangup signal as follows:
+.Bd -literal -offset indent
+kill -s HUP `cat /var/run/mountd.pid`
+.Ed
+.Pp
+After sending the
+.Dv SIGHUP ,
+check the
+.Xr syslogd 8
+output to see whether
+.Xr mountd 8
+logged any parsing errors in the
+.Nm
+file.

+.Sh BUGS
+The export options are tied to the local mount points in the kernel and
+must be non-contradictory for any exported subdirectory of the local
+server mount point.
+It is recommended that all exported directories within the same server
+filesystem be specified on adjacent lines going down the tree.
+You cannot specify a hostname that is also the name of a netgroup.
+Specifying the full domain specification for a hostname can normally
+circumvent the problem.

+.Sh SYNOPSIS
+.Nm
+.Op Fl 2dlnr
+.Op Ar exportsfile
+.Sh DESCRIPTION
+The
+.Nm
+utility is the server for
+.Tn NFS
+mount requests from other client machines.
+It listens for service requests at the port indicated in the
+.Tn NFS
+server specification; see
+.%T "Network File System Protocol Specification" ,
+RFC1094, Appendix A and
+.%T "NFS: Network File System Version 3 Protocol Specification" ,
+Appendix I.
+.Pp
+The following options are available:
+.Bl -tag -width indent
+.It Fl 2
+Allow the administrator to force clients to use only the
+version 2
+.Tn NFS
+protocol to mount filesystems from this server.
+.It Fl d
+Output debugging information.
+.It Fl l
+Cause all succeeded
+.Nm
+requests to be logged.
+.It Fl n
+Allow non-root mount requests to be served.
+This should only be specified if there are clients such as PC's,
+that require it.
+It will automatically clear the vfs.nfsrv.nfs_privport sysctl flag, which
+controls if the kernel will accept NFS requests from reserved ports only.
+.It Fl r
+Allow mount RPCs requests for regular files to be served.
+Although this seems to violate the mount protocol specification,
+some diskless workstations do mount requests for
+their swapfiles and expect them to be regular files.
+Since a regular file cannot be specified in
+.Pa /etc/exports ,
+the entire filesystem in which the swapfiles resides
+will have to be exported with the
+.Fl alldirs
+flag.
+.It Ar exportsfile
+Specify an alternate location
+for the exports file.
+.El
+.Pp
+When
+.Nm
+is started,
+it loads the export host addresses and options into the kernel
+using the
+.Xr mount 2
+system call.
+After changing the exports file,
+a hangup signal should be sent to the
+.Nm
+daemon
+to get it to reload the export information.
+After sending the SIGHUP
+(kill \-s HUP `cat /var/run/mountd.pid`),
+check the syslog output to see if
+.Nm
+logged any parsing
+errors in the exports file.
+.Pp
+If
+.Nm
+detects that the running kernel does not include
+.Tn NFS
+support, it will attempt to load a loadable kernel module containing
+.Tn NFS
+code, using
+.Xr kldload 8
+by way of
+.Xr vfsload 3 .
+If this fails, or no
+.Tn NFS
+KLD was available,
+.Nm
+exits with an error.
+.Sh FILES

+.Dt NETGROUP 5
+.Os
+.Sh NAME
+.Nm netgroup
+.Nd defines network groups
+.Sh SYNOPSIS
+.Nm
+.Sh DESCRIPTION
+The
+.Nm
+file
+specifies ``netgroups'', which are sets of
+.Sy (host, user, domain)
+tuples that are to be given similar network access.
+.Pp
+Each line in the file
+consists of a netgroup name followed by a list of the members of the
+netgroup.
+Each member can be either the name of another netgroup or a specification
+of a tuple as follows:
+.Bd -literal -offset indent
+(host, user, domain)
+.Ed
+.Pp
+where the
+.Sy host ,
+.Sy user ,
+and
+.Sy domain
+are character string names for the corresponding component.
+Any of the comma separated fields may be empty to specify a ``wildcard'' value
+or may consist of the string ``-'' to specify ``no valid value''.
+The members of the list may be separated by whitespace and/or commas;
+the ``\e'' character may be used at the end of a line to specify
+line continuation.
+Lines are limited to 1024 characters.
+The functions specified in
+.Xr getnetgrent 3
+should normally be used to access the
+.Nm
+database.
+.Pp
+Lines that begin with a # are treated as comments.
+.Sh NIS/YP INTERACTION
+On most other platforms,
+.Nm Ns s
+are only used in conjunction with
+.Tn NIS
+and local
+.Pa /etc/netgroup
+files are ignored.
+With
+.Fx ,
+.Nm Ns s
+can be used with either
+.Tn NIS
+or local files, but there are certain
+caveats to consider.
+The existing
+.Nm
+system is extremely inefficient where
+.Fn innetgr 3
+lookups are concerned since
+.Nm
+memberships are computed on the fly.
+By contrast, the
+.Tn NIS
+.Nm
+database consists of three separate maps (netgroup, netgroup.byuser
+and netgroup.byhost) that are keyed to allow
+.Fn innetgr 3
+lookups to be done quickly.
+The
+.Fx
+.Nm
+system can interact with the
+.Tn NIS
+.Nm
+maps in the following ways:
+.Bl -bullet -offset indent
+.It
+If the
+.Pa /etc/netgroup
+file does not exist, or it exists and is empty, or
+it exists and contains only a
+.Sq + ,
+and
+.Tn NIS
+is running,
+.Nm
+lookups will be done exclusively through
+.Tn NIS ,
+with
+.Fn innetgr 3
+taking advantage of the netgroup.byuser and
+netgroup.byhost maps to speed up searches.
+(This
+is more or less compatible with the behavior of SunOS and
+similar platforms.)
+.It
+If the
+.Pa /etc/netgroup
+exists and contains only local
+.Nm
+information (with no
+.Tn NIS
+.Sq +
+token), then only the local
+.Nm
+information will be processed (and
+.Tn NIS
+will be ignored).
+.It
+If
+.Pa /etc/netgroup
+exists and contains both local netgroup data
+.Pa and
+the
+.Tn NIS
+.Sq +
+token, the local data and the
+.Tn NIS
+netgroup
+map will be processed as a single combined
+.Nm
+database.
+While this configuration is the most flexible, it
+is also the least efficient: in particular,
+.Fn innetgr 3
+lookups will be especially slow if the
+database is large.
+.El
+.Sh FILES
+.Bl -tag -width /etc/netgroup -compact
+.It Pa /etc/netgroup
+the netgroup database
+.El
+.Sh SEE ALSO
+.Xr getnetgrent 3 ,
+.Xr exports 5
+.Sh COMPATIBILITY
+The file format is compatible with that of various vendors, however it
+appears that not all vendors use an identical format.
+.Sh BUGS
+The interpretation of access restrictions based on the member tuples of a
+netgroup is left up to the various network applications.
+Also, it is not obvious how the domain specification
+applies to the
+.Bx
+environment.
+.Pp
+The
+.Nm
+database should be stored in the form of a
+hashed
+.Xr db 3
+database just like the
+.Xr passwd 5
+database to speed up reverse lookups.

+.Sh DESCRIPTION
+The mouse daemon
+.Nm
+and the console driver work together to support
+mouse operation in the text console and user programs.
+They virtualize the mouse and provide user programs with mouse data
+in the standard format
+(see
+.Xr sysmouse 4 ) .
+.Pp
+The mouse daemon listens to the specified port for mouse data,
+interprets and then passes it via ioctls to the console driver.
+The mouse daemon
+reports translation movement, button press/release
+events and movement of the roller or the wheel if available.
+The roller/wheel movement is reported as ``Z'' axis movement.
+.Pp
+The console driver will display the mouse pointer on the screen
+and provide cut and paste functions if the mouse pointer is enabled
+in the virtual console via
+.Xr vidcontrol 1 .
+If
+.Xr sysmouse 4
+is opened by the user program, the console driver also passes the mouse
+data to the device so that the user program will see it.
+.Pp
+If the mouse daemon receives the signal
+.Dv SIGHUP ,
+it will reopen the mouse port and reinitializes itself.
+Useful if
+the mouse is attached/detached while the system is suspended.
+.Pp
+The following options are available:
+.Bl -tag -width indent
+.It Fl 3
+Emulate the third (middle) button for 2-button mice.
+It is emulated
+by pressing the left and right physical buttons simultaneously.
+.It Fl C Ar threshold
+Set double click speed as the maximum interval in msec between button clicks.
+Without this option, the default value of 500 msec will be assumed.
+This option will have effect only on the cut and paste operations
+in the text mode console.
+The user program which is reading mouse data
+via
+.Xr sysmouse 4
+will not be affected.
+.It Fl D
+Lower DTR on the serial port.
+This option is valid only if
+.Ar mousesystems
+is selected as the protocol type.
+The DTR line may need to be dropped for a 3-button mouse
+to operate in the
+.Ar mousesystems
+mode.
+.It Fl E Ar timeout
+When the third button emulation is enabled
+(see above),
+the
+.Nm
+daemon waits
+.Ar timeout
+msec at most before deciding whether two buttons are being pressed
+simultaneously.
+The default timeout is 100 msec.
+.It Fl F Ar rate
+Set the report rate (reports/sec) of the device if supported.
+.It Fl I Ar file
+Write the process id of the
+.Nm
+daemon in the specified file.
+Without this option, the process id will be stored in
+.Pa /var/run/moused.pid .
+.It Fl P
+Do not start the Plug and Play COM device enumeration procedure
+when identifying the serial mouse.
+If this option is given together with the
+.Fl i
+option, the
+.Nm
+command will not be able to print useful information for the serial mouse.
+.It Fl R
+Lower RTS on the serial port.
+This option is valid only if
+.Ar mousesystems
+is selected as the protocol type by the
+.Fl t
+option below.
+It is often used with the
+.Fl D
+option above.
+Both RTS and DTR lines may need to be dropped for
+a 3-button mouse to operate in the
+.Ar mousesystems
+mode.
+.It Fl S Ar baudrate
+Select the baudrate for the serial port (1200 to 9600).
+Not all serial mice support this option.
+.It Fl a Ar X Ns Op , Ns Ar Y
+Accelerate or decelerate the mouse input.
+This is a linear acceleration only.
+Values less than 1.0 slow down movement, values greater than 1.0 speed it
+up.
+Specifying only one value sets the acceleration for both axes.
+.It Fl c
+Some mice report middle button down events
+as if the left and right buttons are being pressed.
+This option handles this.
+.It Fl d
+Enable debugging messages.
+.It Fl f
+Do not become a daemon and instead run as a foreground process.
+Useful for testing and debugging.
+.It Fl i Ar info
+Print specified information and quit.  Available pieces of
+information are:
+.Pp
+.Bl -tag -compact -width modelxxx
+.It Ar port
+Port (device file) name, i.e.\&
+.Pa /dev/cuaa0 ,
+.Pa /dev/mse0
+and
+.Pa /dev/psm0 .
+.It Ar if
+Interface type: serial, bus, inport or ps/2.
+.It Ar type
+Protocol type.
+It is one of the types listed under the
+.Fl t
+option below or
+.Ar sysmouse
+if the driver supports the
+.Ar sysmouse
+data format standard.
+.It Ar model
+Mouse model.  The
+.Nm
+command may not always be able to identify the model.
+.It Ar all
+All of the above items.  Print port, interface, type and model in this order
+in one line.
+.El
+.Pp
+If the
+.Nm
+command cannot determine the requested information, it prints ``unknown''
+or ``generic''.
+.It Fl m Ar N=M
+Assign the physical button
+.Ar M
+to the logical button
+.Ar N .
+You may specify as many instances of this option as you like.
+More than one physical button may be assigned to a logical button at the
+same time.
+In this case the logical button will be down,
+if either of the assigned physical buttons is held down.
+Do not put space around `='.
+.It Fl p Ar port
+Use
+.Ar port
+to communicate with the mouse.
+.It Fl r Ar resolution
+Set the resolution of the device; in Dots Per Inch, or
+.Ar low ,
+.Ar medium-low ,
+.Ar medium-high
+or
+.Ar high .
+This option may not be supported by all the device.
+.It Fl s
+Select a baudrate of 9600 for the serial line.
+Not all serial mice support this option.
+.It Fl t Ar type
+Specify the protocol type of the mouse attached to the port.
+You may explicitly specify a type listed below, or use
+.Ar auto
+to let the
+.Nm
+command to automatically select an appropriate protocol for the given
+mouse.
+If you entirely ommit this options in the command line,
+.Fl t Ar auto
+is assumed.
+Under normal circumstances,
+you need to use this option only if the
+.Nm
+command is not able to detect the protocol automatically
+(see the
+.Sx "Configuring Mouse Daemon" ) .
+.Pp
+Note that if a protocol type is specified with this option, the
+.Fl P
+option above is implied and Plug and Play COM device enumeration
+procedure will be disabled.
+.Pp
+Also note that if your mouse is attached to the PS/2 mouse port, you should
+always choose
+.Ar auto
+or
+.Ar ps/2 ,
+regardless of the brand and model of the mouse.  Likewise, if your
+mouse is attached to the bus mouse port, choose
+.Ar auto
+or
+.Ar busmouse .
+Serial mouse protocols will not work with these mice.
+.Pp
+For the USB mouse, the protocol must be
+.Ar auto .
+No other protocol will work with the USB mouse.
+.Pp
+Valid types for this option are
+listed below.
+.Pp
+For the serial mouse:
+.Bl -tag -compact -width mousesystemsxxx
+.It Ar microsoft
+Microsoft serial mouse protocol.  Most 2-button serial mice use this protocol.
+.It Ar intellimouse
+Microsoft IntelliMouse protocol.  Genius NetMouse, ASCII Mie Mouse,
+Logitech MouseMan+ and FirstMouse+ use this protocol too.
+Other mice with a roller/wheel may be compatible with this protocol.

+Note also that some mice think left is the negative horizontal direction,

+Moreover, there are some mice whose two wheels are both mounted vertically,
+and the direction of the second vertical wheel does not match the

+.El
+.El
+.Ss Configuring Mouse Daemon
+The first thing you need to know is the interface type
+of the mouse you are going to use.
+It can be determined by looking at the connector of the mouse.
+The serial mouse has a D-Sub female 9- or 25-pin connector.
+The bus and InPort mice have either a D-Sub male 9-pin connector
+or a round DIN 9-pin connector.
+The PS/2 mouse is equipped with a small, round DIN 6-pin connector.
+Some mice come with adapters with which the connector can
+be converted to another.  If you are to use such an adapter,
+remember the connector at the very end of the mouse/adapter pair is
+what matters.
+The USB mouse has a flat rectangular connector.
+.Pp
+The next thing to decide is a port to use for the given interface.
+For the bus, InPort and PS/2 mice, there is little choice:
+the bus and InPort mice always use
+.Pa /dev/mse0 ,
+and the PS/2 mouse is always at
+.Pa /dev/psm0 .
+There may be more than one serial port to which the serial
+mouse can be attached.  Many people often assign the first, built-in
+serial port
+.Pa /dev/cuaa0
+to the mouse.
+You can attach multiple USB mice to your system or to your USB hub.
+They are accessible as
+.Pa /dev/ums0 , /dev/ums1 ,
+and so on.
+.Pa
+You may want to create a symbolic link
+.Pa /dev/mouse
+pointing to the real port to which the mouse is connected, so that you
+can easily distinguish which is your ``mouse'' port later.
+.Pp
+The next step is to guess the appropriate protocol type for the mouse.
+The
+.Nm
+command may be able to automatically determine the protocol type.
+Run the
+.Nm
+command with the
+.Fl i
+option and see what it says.  If the command can identify
+the protocol type, no further investigation is necessary on your part.
+You may start the daemon without explicitly specifying a protocol type
+(see
+.Sx EXAMPLES ) .
+.Pp
+The command may print
+.Ar sysmouse
+if the mouse driver supports this protocol type.
+.Pp
+Note that the
+.Dv type
+and
+.Dv model
+printed by the
+.Fl i
+option do not necessarily match the product name of the pointing device
+in question, but they may give the name of the device with which it is
+compatible.
+.Pp
+If the
+.Fl i
+option yields nothing, you need to specify a protocol type to the
+.Nm
+command by the
+.Fl t
+option.
+You have to make a guess and try.
+There is rule of thumb:
+.Pp
+.Bl -enum -compact -width 1.X
+.It
+The bus and InPort mice always use
+.Ar busmouse
+protocol regardless of the brand of the mouse.
+.It
+The
+.Ar ps/2
+protocol should always be specified for the PS/2 mouse
+regardless of the brand of the mouse.
+.It
+You must specify the
+.Ar auto
+protocol for the USB mouse.
+.It
+Most 2-button serial mice support the
+.Ar microsoft
+protocol.
+.It
+3-button serial mice may work with the
+.Ar mousesystems
+protocol.
+If it does not, it may work with the
+.Ar microsoft
+protocol although
+the third (middle) button will not function.
+3-button serial mice may also work with the
+.Ar mouseman
+protocol under which the third button may function as expected.
+.It
+3-button serial mice may have a small switch to choose between ``MS''
+and ``PC'', or ``2'' and ``3''.
+``MS'' or ``2'' usually mean the
+.Ar microsoft
+protocol.
+``PC'' or ``3'' will choose the
+.Ar mousesystems
+protocol.
+.It
+If the mouse has a roller or a wheel, it may be compatible with the
+.Ar intellimouse
+protocol.
+.El
+.Pp
+To test if the selected protocol type is correct for the given mouse,
+enable the mouse pointer in the current virtual console,
+.Pp
+.Dl vidcontrol -m on
+.Pp
+start the mouse daemon in the foreground mode,
+.Pp
+.Dl moused -f -p Ar _selected_port_ -t Ar _selected_protocol_
+.Pp
+and see if the mouse pointer travels correctly
+according to the mouse movement.
+Then try cut & paste features by
+clicking the left, right and middle buttons.
+Type ^C to stop
+the command.
+.Ss Multiple Mice
+As many instances of the mouse daemon as the number of mice attached to
+the system may be run simultaneously; one
+instance for each mouse.
+This is useful if the user wants to use the built-in PS/2 pointing device
+of a laptop computer while on the road, but wants to use a serial
+mouse when s/he attaches the system to the docking station in the office.
+Run two mouse daemons and tell the application program
+(such as the
+.Tn "X\ Window System" )
+to use
+.Xr sysmouse ,
+then the application program will always see mouse data from either mice.
+When the serial mouse is not attached, the corresponding mouse daemon
+will not detect any movement or button state change and the application
+program will only see mouse data coming from the daemon for the
+PS/2 mouse.
+In contrast when both mice are attached and both of them
+are moved at the same time in this configuration,
+the mouse pointer will travel across the screen just as if movement of
+the mice is combined all together.

+.Sh CAVEATS
+The
+.Nm
+command does not currently work with the alternative console driver
+.Xr pcvt 4 .
+.Pp
+Many pad devices behave as if the first (left) button were pressed if
+the user `taps' the surface of the pad.
+In contrast, some ALPS GlidePoint and Interlink VersaPad models
+treat the tapping action
+as fourth button events.
+Use the option ``-m 1=4'' for these models
+to obtain the same effect as the other pad devices.
+.Pp
+Cut and paste functions in the virtual console assume that there
+are three buttons on the mouse.
+The logical button 1 (logical left) selects a region of text in the
+console and copies it to the cut buffer.
+The logical button 3 (logical right) extends the selected region.
+The logical button 2 (logical middle) pastes the selected text
+at the text cursor position.
+If the mouse has only two buttons, the middle, `paste' button
+is not available.
+To obtain the paste function, use the
+.Fl 3
+option to emulate the middle button, or use the
+.Fl m
+option to assign the physical right button to the logical middle button:
+``-m 2=3''.

+.Sh STANDARDS
+The
+.Nm
+command partially supports
+.Dq Plug and Play External COM Device Specification
+in order to support PnP serial mice.
+However, due to various degrees of conformance to the specification by
+existing serial mice, it does not strictly follow the version 1.0 of the
+standard.
+Even with this less strict approach,
+it may not always determine an appropriate protocol type
+for the given serial mouse.

+     **
+     ** The following lines take care of the Logitech MouseMan protocols.
+     **
+     ** NOTE: There are different versions of both MouseMan and TrackMan!
+     **       Hence I add another protocol P_LOGIMAN, which the user can
+     **       specify as MouseMan in his XF86Config file. This entry was
+     **       formerly handled as a special case of P_MS. However, people
+     **       who don't have the middle button problem, can still specify
+     **       Microsoft and use P_MS.
+     **
+     ** By default, these mice should use a 3 byte Microsoft protocol
+     ** plus a 4th byte for the middle button. However, the mouse might
+     ** have switched to a different protocol before we use it, so I send
+     ** the proper sequence just in case.
+     **
+     ** NOTE: - all commands to (at least the European) MouseMan have to
+     **         be sent at 1200 Baud.
+     **       - each command starts with a '*'.
+     **       - whenever the MouseMan receives a '*', it will switch back
+     **	 to 1200 Baud. Hence I have to select the desired protocol
+     **	 first, then select the baud rate.
+     **
+     ** The protocols supported by the (European) MouseMan are:
+     **   -  5 byte packed binary protocol, as with the Mouse Systems
+     **      mouse. Selected by sequence "*U".
+     **   -  2 button 3 byte MicroSoft compatible protocol. Selected
+     **      by sequence "*V".
+     **   -  3 button 3+1 byte MicroSoft compatible protocol (default).
+     **      Selected by sequence "*X".
+     **
+     ** The following baud rates are supported:
+     **   -  1200 Baud (default). Selected by sequence "*n".
+     **   -  9600 Baud. Selected by sequence "*q".
+     **
+     ** Selecting a sample rate is no longer supported with the MouseMan!
+     ** Some additional lines in xf86Config.c take care of ill configured
+     ** baud rates and sample rates. (The user will get an error.)

+
+	IP Multicast Extensions for BSD-Derived Unix Systems
+	Multicast Routing Daemon
+
+	Release 3.9-beta3
+	February 28, 1998
+
+	available from parcftp.xerox.com,
+	file pub/net-research/ipmulti/beta-test/mrouted3.9-beta3.tar.Z
+	binaries:
+	pub/net-research/ipmulti/beta-test/mrouted3.9-beta3-sparc-sunos41x.tar.Z
+	pub/net-research/ipmulti/beta-test/mrouted3.9-beta3-sparc-solaris2.tar.Z

+	pub/net-research/ipmulti/beta-test/mrouted3.9-beta3-sgi-irix6.tar.Z
+
+Note: The 3.9 release is mrouted-only, and will run on top of a 3.5 kernel.
+It is a drop-in replacement for mrouted 3.5, 3.6, 3.7 or 3.8.
+
+NOTE WELL: This is a beta-test release of mrouted.  The basic
+functionality has been extensively tested in CAIRN and other
+testbeds, but it is expected to have bugs.  Please report bugs to Bill
+Fenner <fenner@parc.xerox.com>.
+
+
+The 3.9-beta3 release fixes the following bugs:
+  o There was a bug handling routing updates which caused random black
+    holes.
+
+  o There was a race condition in the timer handlers causing free'd memory
+    to sometimes get touched.
+
+  o "allow_nonpruners" wasn't allowed in the configuration file (and almost
+    nobody noticed! - probably a good sign)
+
+  o When a prune times out and the source has been active "recently",
+    mrouted now waits for further traffic instead of triggering a new
+    prune.
+
+  o mrouted now ignores unreachable routes when making a routing decision
+    (previously it would blackhole, now it can find a less-specific)
+
+The 3.9-beta3 release has the following new features:
+  o A "blaster" keyword for mrouted.conf, to turn on handling of routers
+    (mostly ciscos) which overwhelm the socket buffers by blasting the
+    whole routing table at once.
+
+  o A "notransit" keyword; routes learned on a "notransit" vif will not be
+    readvertised onto another "notransit" vif.
+
+  o The 500kbps default rate limit on tunnels has been removed.
+
+  o An ICMP listener which logs ICMP errors which appear to be in response to
+    tunnel packets that we sent.
+
+  o A tunnel traffic encapsulator, which encapsulates control traffic
+    inside the tunnel instead of unicasting it "beside" the tunnel.
+    This is turned off by default; use "beside off" to turn it on.
+
+  o A "force_leaf" flag to ignore any potential neighbors on a given interface.
+
+
+=========
+3.9-beta2
+June 11, 1997
+
+The 3.9-beta2 release fixes the following bugs:
+  o There was a bug in 3.9-beta1's raw socket buffer processing that
+    would cause an immediate lockup on startup on some systems.
+
+  o RSRR would not clear out the group membership information if
+    further notification of changes to this route entry was not possible.
+
+There is no need to upgrade to 3.9-beta2 if you are not experiencing
+one of the aforementioned bugs.
+
+=========
+3.9-beta1
+June 6, 1997
+
+The 3.9-beta1 release has the following known bugs:
+
+  o The startup message doesn't print properly if you have too many
+    interfaces.
+
+The 3.9-beta1 release fixes the following bugs:
+
+  o mrouted did not properly keep track of subordinates, and would not
+    time out subordinateness.  This caused 2 major problems:
+    1. pruning did not happen when there were equal-cost paths to
+       the same multi-access link
+    2. subordinateness which did not get cancelled by a non-poisoned
+       route (e.g. in the face of route filtering) did not time out,
+       causing traffic to continue to flow.
+
+  o mrouted's IGMPv2 processing when it is not the querier now
+    conforms to draft-ietf-idmr-igmp-v2-06.txt Thanks to Lorenzo
+    VICISANO <L.Vicisano@cs.ucl.ac.uk> for finding a problem.
+
+  o mrouted is much more careful about forgetting prunes; 3.8
+    would forget prunes whenever any route change ocurred.
+
+The 3.9-beta1 release has the following new features:
+
+  o Longer prune lifetimes (2 hours) by default.  Prune lifetimes may
+    be configured per-vif, with the "prune_lifetime N" mrouted.conf
+    configuration file entry (where N is in seconds).  This helps to
+    work around the black holes caused on restart when you have a Cisco
+    upstream which does not handle genid's; if this is your situation
+    the recommended value is 300.
+
+  o mrouted's behavior of flooding new routes by default at startup
+    in order to speed healing of paths during startup can be turned off
+    per-vif or globally with the "noflood" configuration option.
+    Turning this option off means you are likely to experience
+    black holes for a minute or two when you restart a router.  The
+    default is to flood for a minute or two until mrouted is able to
+    learn subordinate relationships.
+
+  o mrouted now retransmits prunes by default on point-to-point links.
+    prune retransmission can be turned on or off per vif via the
+    "rexmit_prunes [on|off]" mrouted.conf command.  Prune retransmission
+    helps on lossy links, and also helps when a router has forgotten
+    about a prune (e.g. if it is out of memory and needs to shed state,
+    or due to a bug).
+
+  o The new "passive" mode causes mrouted to not actively send probes
+    looking for neighbors.  This allows a dialup link to become quiescent
+    if there is no DVMRP neighbor on the other end.  Configuring
+    "passive" on both ends of a link will cause it to never come up.
+
+  o mrouted defaults to not peering with DVMRP routers that do not
+    prune.  Use the "allow_nonpruners" mrouted.conf option on a vif
+    on which you want to allow such peerings.
+
+  o mrouted now allows route filtering.  mrouted.conf syntax:
+	accept 13/8
+
+	accepts all routes matching 13/8 (e.g. accepts
+	13.2.116/22).  If you want to accept only exactly
+	13/8, use
+
+	accept 13/8 exact
+
+	deny 10/8 64/2 130/8 exact 172/8 exact
+
+	denies some common MBone martians
+
+      Only "accept" or "deny" is allowed, no combinations.
+
+      Add "bidir" to apply the filter to output too, otherwise
+      it's input only.
+
+    Expected usage:
+    - Providers filter routes that customers send them
+    - Martian removal
+    - Topology modification (e.g. don't let the existence of
+    private tunnel foo out into the world).
+
+
+  o mrouted now malloc's the buffer it uses for SIOCGIFCONF, to allow
+    for more interfaces.  Thanks to Danny Mitzel
+
+  o mrouted now ignores multiple entries for a single interface
+    name (temporary hack until mrouted understands interface aliases)
+
+  o mrouted's "-d" flag has been modified to accept the names of the
+    systems which you would like to debug.
+    packet, prunes, routes, peers, cache, timeout, interface,
+    membership, traceroute, igmp
+
+  o mrouted now times neighbors out fater, and fully detects and
+    ignores routes from one-way peerings.
+
+  o mrouted's route processing has been sped up, especially at startup.
+
+  o mrouted uses the biggest SO_RCVBUF the operating system allows
+    (up to 256Kbytes)
+
+  o mrouted uses TOS 0xc0 ("Internet Control") for DVMRP messages.
+
+===========
+Release 3.8
+November 29, 1995
+
+The 3.8 release fixes the following bugs:
+
+  o mrouted would fail to forget prunes when a neighbor went away,
+    thus potentially sending traffic down a tunnel after the tunnel
+    endpoint has gone down.  This was due to some research code making
+    it into the "emergency" 3.7 release, sigh.
+
+  o mrouted could send prunes with negative lifetimes.  This causes
+    slightly higher prune traffic but shouldn't be any major problem.
+
+===========
+Release 3.7
+November 28, 1995
+
+The 3.7 release fixes the following bugs:
+
+  o mrouted now ignores route reports that include bogus netmasks.
+    There was a bug in 3.5 that would mangle default routes into
+    tens of bogus routes; this should prevent that bug from killing
+    the MBONE.
+
+    This solution can cause route flaps and black holes until the
+    3.5's are gone or all of the 3.5's neighbors are 3.7 .
+
+  o mrouted now ignores duplicate routes.  Ciscos and the above 3.5
+    bug could cause two copies of the same route to appear in a single
+    routing update; mrouted would insert two copies of the same route
+    into its routing table and wreak all sorts of havoc.
+
+  o mrouted now sends a group-specific query for both retransmissions
+    of a g-s query; previous versions sent a general query the second
+    time.
+
+  o mrouted now loops back multicasted mtrace responses and
+    group-specific membership queries
+
+  o mrouted now performs deterministic tiebreaking between two
+    neighbors on the same vif.
+
+  o mrouted now only does duplicate suppression on traceroute requests,
+    not all traceroute packets, so that a loop can be nicely detected
+    via a duplicate router instead of just a timeout.
+
+  o the buffer size that mrouted uses has been increased to allow
+    more than 16 hops in mtrace messages.
+
+  o mtrace's hop-by-hop termination is now more likely to be correct.
+
+  o mrinfo now waits for the responses to its retransmitted queries.
+
+The 3.7 release has the following new features:
+
+  o The configuration file can accept a hostname as the other end
+    of a tunnel.  There must be a single name->ip mapping for the
+    given name, however, or mrouted will fail to start up.
+
+  o mrinfo now sends requests to all interfaces of a multihomed host.
+
+  o mtrace's passive mode has been implemented.
+
+  o The first screen of mtrace statistics is shorter and more likely
+    to fit on one screen.
+
+===========
+Release 3.6
+June 26, 1995
+
+The 3.6 release fixes the following bugs:
+
+  o mrouted would dump core when attempting to report no routes (i.e. upon
+    startup, if you have no enabled phyint's)
+
+  o mrouted would dump core if requested to traceroute a source for which it
+    had no route
+
+  o neighbor flags were not always properly updated on probe or report
+
+  o mrouted would sometimes reply to a multicast traceroute on a disabled
+    phyint; now it uses the first configured phyint to reply to traceroutes.
+
+  o host routes (i.e. netmask 0xffffffff) works now; it was discarding
+    IGMP from the host because it was coming from the "broadcast address"
+    of the subnet.
+
+  o send_igmp() now treats the failure to send an mtrace or a neighbor
+    reply as informational, as opposed to warning.
+
+  o mrouted would go into an infinite loop trying to respond to a traceroute
+    for a source with a netmask of 0xffffffff.
+
+  o vifs_with_neighbors was not being reset if the mrouted was restarted
+    with SIGHUP
+
+  o the default route was not being properly advertised to neighbors (although
+    it was accepted if it was advertised to it)
+
+  o ANSI-fication for those who it helps, still-K&R-ish for those it doesn't.
+
+  o mtrace now attempts to trace three hops past a non-responding router,
+    in the hopes that it does support traceroute but just couldn't respond
+    (i.e. unicast didn't work and it can't source multicast because all its
+    phyints are disabled).
+
+  o mrinfo now times out even on a multicast router.
+
+
+===========
+Release 3.5
+May 8, 1995
+
+The 3.5 release has the following new features:
+
+  o The kernel and mrouted make sure that each is the correct version, to
+    prevent problems with mismatched kernel/mrouted versions.  A too-old
+    mrouted will die with the error:
+
+    can't enable DVMRP routing in kernel: Option not supported by protocol
+
+  o mrouted can accept and propogate a default route (essential for
+    heirarchical multicast routing)
+
+  o Kernel route cache keeps source-specific routes instead of subnet routes,
+    eliminating hashing and longest-match problems.
+    (allows classless routing, longest-match and default routing)
+
+  o Cached kernel routes only get deleted if no traffic is flowing, to
+    facilitate multicast traceroute
+
+  o mrouted has a new configuration file parser, which provides better error
+    messages than before, and allows named boundaries (see man page)
+
+  o added "netmask" to phyint configuration, at the suggestion of
+    Anders Klemets
+
+  o System V and FreeBSD compatibility from John Brezak <brezak@ch.hp.com>
+
+  o phyint's can have additional subnets configured, for people with
+    multiple subnets on one physical network.  mrouted.conf syntax is
+    altnet 1.2.3.0, or altnet 1.2.3.0/24 if you need to specify
+    a different netmask.  There can be as many altnet statements
+    as you need.
+
+  o both mrouted and the kernel now support classless addresses.
+
+  o the kernel supports PIM assert processing by notifying the router
+    when a packet arrives on the wrong interface
+
+  o the kernel keeps additional counters, and mrouted can be compiled to
+    support SNMP and the Multicast MIB
+
+  o the packet classifier in the kernel now uses the following udp port
+    ranges:
+      [0, 16384) - lowest priority, unclassified
+      [16384, 32768) - highest priority, i.e. audio
+      [32768, 49152) - medium priority, i.e. whiteboard
+      [49152, 65536) - low priority, i.e. video
+    A future release of a session directory will allocate ports in these
+    ranges.
+
+  o the configuration code has been modified to default tunnels' rate_limit
+    parameters to 500kbps.  This is easily modified with a rate_limit keyword
+    in mrouted.conf, but should be a good default for the MBONE in general.
+
+  o The tunnel sending code now caches a route for ip_output(), this should
+    help performance on machines with lots of tunnels.
+
+  o Dispatching for de-capsulating packets is now via protosw[], making
+    reception of other raw protocols more efficient
+
+  o Neighbor capabilities are discovered via a bitmask as opposed to
+    version number.
+
+  o Multicast traceroute code improved
+
+  o mrouted can be compiled with Routing Support for Resource Reservation
+    (RSRR), required for RSVP.
+
+
+The 3.5 release fixes the following bugs:
+
+  o The IGMPv2 query timeout field was interpreted as being in units of
+    200ms as opposed to 100ms, thus the maximum timeout was set to twice
+    the expected value.  This is not fatal, as mrouted always queries
+    twice in the expectation that a packet could get loss, but it does
+    make it less robust in the face of packet loss.
+
+  o IGMP could report membership in local-only groups (i.e. 224.0.0.X)
+
+  o IGMP could get confused by hearing its own new membership reports, thus
+    a router would never perform fast leave.
+
+  o IGMP could reset timers for the wrong interface.
+
+  o mrouted put a bogus value in the maximum timeout field of IGMPv2 query
+    packets.
+
+  o Non-querier mrouters would respond to IGMP leave messages
+
+  o mrouted was not performing fast leave properly
+
+  o If the last member goes away on a transit network, the upstream router
+    would stop forwarding even if there are downstream members.
+
+  o Kernel hash function improved
+
+  o Eliminated possibility of panic(): timeout in cache maintenance
+
+  o Reordered resource allocation when sending upcall to handle failure properly
+
+  o some endian-ness bugs squashed in mrouted, probably more to go.
+
+  o Multicast traceroute could send a reply on a disabled interface.
+
+
+This release consists of the following files:
+
+
+	README-3.8.mrouted			- this file
+	
+	mrouted/*				- version 3.8 of mrouted,
+						  mrinfo, map-mbone and
+						  mtrace.
+
+	ifconfig/*				- Changes to ifconfig to
+						  show multicast interfaces
+
+	netstat/*				- Diffs to netstat

+
+	mtest/*					- utility for testing
+						  multicast group 
+						  membership
+
+
+MROUTED 3.8
+
+Mrouted 3.8 has two optional features: SNMP and RSRR.  RSRR support
+is required for running RSVP; the SNMP code, with the help of the
+ISODE snmpd, implements both the Multicast MIB and the DVMRP MIB.
+
+RSRR
+----
+Routing Support for Resource Reservations (RSRR) was contributed by
+Daniel Zappala <daniel@isi.edu>.
+
+To enable RSRR support, uncomment the three lines starting with
+RSRR near the top of the Makefile and "make clean; make".  Or use
+the prebuilt binary, mrouted.rsrr .
+
+RSRR allows RSVP to query mrouted for its routing entry for a particular
+source-group pair.  Using the routing entry and the IP_MULTICAST_VIF
+socket call, RSVP can forward distinct control messages out each
+outgoing interface.  This version of mrouted supports RSRR messages
+using a Unix datagram socket.
+
+RSRR currently includes two pairs of query-reply messages.  RSVP sends
+an Initial Query when it starts.  Mrouted responds with an Initial Reply
+that includes the set of vifs it is using, flagging those that are
+administratively disabled.  When RSVP needs the routing entry for a
+source-group pair, it sends a Route Query.  Mrouted responds with a
+Route Reply that includes the incoming vif and outgoing vifs for the
+source-group pair.
+
+RSVP may request route change notification by setting the notification
+bit in the Route Query.  If mrouted can provide route change
+notification for the source-group pair, it sets the notification bit in
+its Route Reply.  When the routing entry for the source-group pair
+changes, mrouted sends an unsolicited Route Reply containing the new
+routing information.  The initial release of mrouted 3.5 did not support
+route change notification and always returned a Route Reply with the
+notification bit cleared.  This release of mrouted provides route change
+notification when possible.
+
+SNMP
+----
+SNMP support was contributed by David Thaler <thalerd@eecs.umich.edu>.
+
+To enable SNMP support, uncomment the six lines near the top of
+the Makefile below the description of SNMP support, or use the
+prebuilt binary, mrouted.snmp or mrouted.rsrr.snmp .
+
+To link the SNMP-capable mrouted, you need the CMU libraries.
+See http://nic.merit.edu/~mbone/ for a full mrouted-snmp distribution.
+
+Make sure to add the "sysName", "sysContact", "sysVersion" and
+"sysLocation" variables to your /etc/mrouted.conf if you want them
+to provide anything other than default values.
+
+Example:
+
+sysName	"tibia"
+sysContact "Bill Fenner <fenner@parc.xerox.com> +1 415 812-4816"
+sysVersion "SunOS 4.1.3 and mrouted 3.8"
+sysLocation "MAXC room, PARC building 35"
+
+The SNMP version of mrouted has an additional command line flag:
+
+  -P snmp_port
+ 
+     Specifies a port for SNMP communication (default 161).  This option
+     should be used when another SNMP daemon already exists.  The
+     preferred alternate port in this case is port 9161.
+
+The mstat(8) program allows querying of statistics using SNMP.

+/*
+ * A DVMRP message consists of an IP header + an IGMP header + (for some types)
+ * zero or more bytes of data.
+ *
+ * For REPORT messages, the data is route information; the route information
+ * consists of one or more lists of the following form:
+ *
+ *		(mask, (origin, metric), (origin, metric), ...)
+ *
+ * where:
+ *
+ *	"mask" is the subnet mask for all the origins in the list.
+ *		It is always THREE bytes long, containing the low-order
+ *		three bytes of the mask (the high-order byte is always
+ *		0xff and therefore need not be transmitted).
+ *
+ *	"origin" is the number of a subnet from which multicast datagrams
+ *		may originate.  It is from one to four bytes long,
+ *		depending on the value of "mask":
+ *			if all bytes of the mask are zero
+ *			    the subnet number is one byte long
+ *			else if the low-order two bytes of the mask are zero
+ *			    the subnet number is two bytes long
+ *			else if the lowest-order byte of the mask is zero
+ *			    the subnet number is three bytes long,
+ *			else
+ *			    the subnet number is four bytes long.
+ *
+ *	"metric" is a one-byte value consisting of two subfields:
+ *		- the high-order bit is a flag which, when set, indicates
+ *		  the last (origin, metric) pair of a list.
+ *		- the low-order seven bits contain the routing metric for
+ *		  the corresponding origin, relative to the sender of the
+ *		  DVMRP report.  The metric may have the value of UNREACHABLE
+ *		  added to it as a "split horizon" indication (so called
+ *		  "poisoned reverse").
+ *
+ * Within a list, the origin subnet numbers must be in ascending order, and
+ * the lists themselves are in order of increasing mask value.  A message may
+ * not exceed 576 bytes, the default maximum IP reassembly size, including
+ * the IP and IGMP headers; the route information may be split across more
+ * than one message if necessary, by terminating a list in one message and
+ * starting a new list in the next message (repeating the same mask value,
+ * if necessary).
+ *
+ * For NEIGHBORS messages, the data is neighboring-router information
+ * consisting of one or more lists of the following form:
+ *
+ *	(local-addr, metric, threshold, ncount, neighbor, neighbor, ...)
+ *
+ * where:
+ *
+ *	"local-addr" is the sending router's address as seen by the neighbors
+ *		     in this list; it is always four bytes long.
+ *	"metric" is a one-byte unsigned value, the TTL `cost' of forwarding
+ *		 packets to any of the neighbors on this list.
+ *	"threshold" is a one-byte unsigned value, a lower bound on the TTL a
+ *		    packet must have to be forwarded to any of the neighbors on
+ *		    this list.
+ *	"ncount" is the number of neighbors in this list.
+ *	"neighbor" is the address of a neighboring router, four bytes long.
+ *
+ * As with REPORT messages, NEIGHBORS messages should not exceed 576 bytes,
+ * including the IP and IGMP headers; split longer messages by terminating the
+ * list in one and continuing in another, repeating the local-addr, etc., if
+ * necessary.
+ *
+ * For NEIGHBORS2 messages, the data is identical to NEIGHBORS except
+ * there is a flags byte before the neighbor count:
+ *
+ *	(local-addr, metric, threshold, flags, ncount, neighbor, neighbor, ...)

+.Nm map-mbone
+.Nd multicast connection mapper
+.Sh SYNOPSIS
+.Nm
+.Op Fl d Ar debug_level
+.Op Fl f
+.Op Fl g
+.Op Fl n
+.Op Fl r Ar retry_count
+.Op Fl t Ar timeout_count
+.Op Ar starting_router
+.Sh DESCRIPTION
+.Nm Map-mbone
+attempts to display all multicast routers that are reachable from the multicast
+.Ar starting_router .
+If not specified on the command line, the default multicast
+.Ar starting_router
+is the localhost.
+.Pp
+.Nm Map-mbone
+traverses neighboring multicast routers by sending the ASK_NEIGHBORS IGMP
+message to the multicast starting_router.
+If this multicast router responds,
+the version number and a list of their neighboring multicast router addresses is
+part of that response.
+If the responding router has recent multicast version
+number, then
+.Nm
+requests additional information such as metrics, thresholds, and flags from the
+multicast router.
+For each new occurrence of neighboring multicast router in
+the reply and provided the flooding option has been selected, then
+.Nm
+asks each of this multicast router for a list of neighbors.
+This search
+for unique routers will continue until no new neighboring multicast routers
+are reported.
+.Pp
+The following options are available:
+.Bl -tag -width indent
+.It Fl d
+Set the debug level.
+When the debug level is greater than the
+default value of 0, addition debugging messages are printed.
+Regardless of
+the debug level, an error condition, will always write an error message and will
+cause
+.Nm
+to terminate.
+Non-zero debug levels have the following effects:
+.Bl -tag -width indent
+.It "level 1"
+packet warnings are printed to stderr.
+.It "level 2"
+all level 1 messages plus notifications down networks are printed to stderr.
+.It "level 3"
+all level 2 messages plus notifications of all packet
+timeouts are printed to stderr.
+.El
+.It Fl f
+Set flooding option.
+Flooding allows the recursive search
+of neighboring multicast routers and is enable by default when starting_router
+is not used.
+.It Fl g
+Set graphing in GraphEd format.
+.It Fl n
+Disable the DNS lookup for the multicast routers names.
+.It Fl r Ar retry_count
+Set the neighbor query retry limit.
+Default is 1 retry.
+.It Fl t Ar timeout_count
+Set the number of seconds to wait for a neighbor query
+reply before retrying.
+Default timeout is 2 seconds.
+.El
+.Sh IMPORTANT NOTE
+.Nm Map-mbone
+must be run as root.

+.Sh NAME
+.Nm mrinfo
+.Nd display configuration info from a multicast router
+.Sh SYNOPSIS
+.Nm
+.Op Fl d Ar debug_level
+.Op Fl r Ar retry_count
+.Op Fl t Ar timeout_count
+.Ar multicast_router
+.Sh DESCRIPTION
+.Nm Mrinfo
+attempts to display the configuration information from the multicast router
+.Ar multicast_router .
+.Pp
+.Nm Mrinfo
+uses the ASK_NEIGHBORS IGMP message to the specified multicast router.
+If this
+multicast router responds, the version number and a list of their neighboring
+multicast router addresses is part of that response.
+If the responding router
+has a recent multicast version number, then
+.Nm
+requests additional information such as metrics, thresholds, and flags from the
+multicast router.
+Once the specified multicast router responds, the
+configuration is displayed to the standard output.
+.Pp
+The following options are available:
+.Bl -tag -width indent
+.It Fl d Ar debug_level
+Set the debug level.
+When the debug level is greater than the
+default value of 0, addition debugging messages are printed.
+Regardless of
+the debug level, an error condition, will always write an error message and will
+cause
+.Nm
+to terminate.
+Non-zero debug levels have the following effects:
+.Bl -tag -width indent
+.It "level 1"
+packet warnings are printed to stderr.
+.It "level 2"
+all level 1 messages plus notifications down networks are printed to stderr.
+.It "level 3"
+all level 2 messages plus notifications of all packet
+timeouts are printed to stderr.
+.El
+.It Fl r Ar retry_count
+Set the neighbor query retry limit.
+Default is 3 retries.
+.It Fl t Ar timeout_count
+Set the number of seconds to wait for a neighbor query
+reply.
+Default timeout is 4 seconds.
+.El
+.Sh SAMPLE OUTPUT
+.Bd -literal
+.Nm mrinfo Ar mbone.phony.dom.net
+127.148.176.10 (mbone.phony.dom.net) [version 3.3]:
+ 127.148.176.10 -> 0.0.0.0 (?) [1/1/querier]
+ 127.148.176.10 -> 127.0.8.4 (mbone2.phony.dom.net) [1/45/tunnel]
+ 127.148.176.10 -> 105.1.41.9 (momoney.com) [1/32/tunnel/down]
+ 127.148.176.10 -> 143.192.152.119 (mbone.dipu.edu) [1/32/tunnel]
+.Ed
+.Pp
+For each neighbor of the queried multicast router, the IP of the queried router
+is displayed, followed by the IP and name of the neighbor.
+In square brackets
+the metric (cost of connection), the treashold (multicast ttl) is displayed.
+If
+the queried multicast router has a newer version number, the type (tunnel,
+srcrt) and status (disabled, down) of the connection is displayed.
+.Sh IMPORTANT NOTE
+.Nm Mrinfo
+must be run as root.

+.Nm mrouted
+.Nd IP multicast routing daemon
+.Sh SYNOPSIS
+.Nm
+.Op Fl c Ar config_file
+.Op Fl d Op Ar debug_level
+.Op Fl p
+.Sh DESCRIPTION
+.Nm Mrouted
+is an implementation of the Distance-Vector Multicast Routing
+Protocol (DVMRP), an earlier version of which is specified in RFC-1075.
+It maintains topological knowledge via a distance-vector routing protocol
+(like RIP, described in RFC-1058), upon which it implements a multicast
+datagram forwarding algorithm called Reverse Path Multicasting.
+.Pp
+.Nm Mrouted
+forwards a multicast datagram along a shortest (reverse) path tree
+rooted at the subnet on which the datagram originates.
+The multicast
+delivery tree may be thought of as a broadcast delivery tree that has
+been pruned back so that it does not extend beyond those subnetworks
+that have members of the destination group.
+Hence, datagrams
+are not forwarded along those branches which have no listeners of the
+multicast group.
+The IP time-to-live of a multicast datagram can be
+used to limit the range of multicast datagrams.
+.Pp
+In order to support multicasting among subnets that are separated by (unicast)
+routers that do not support IP multicasting,
+.Nm
+includes support for
+"tunnels", which are virtual point-to-point links between pairs of
+multicast routers
+located anywhere in an internet.  IP multicast packets are encapsulated for
+transmission through tunnels, so that they look like normal unicast datagrams
+to intervening routers and subnets.  The encapsulation
+is added on entry to a tunnel, and stripped off
+on exit from a tunnel.
+The packets are encapsulated using the IP-in-IP protocol
+(IP protocol number 4).
+Older versions of
+.Nm
+tunneled using IP source routing, which puts a heavy load on some
+types of routers.
+This version does not support IP source route tunnelling.
+.Pp
+The tunnelling mechanism allows
+.Nm
+to establish a virtual internet, for
+the purpose of multicasting only, which is independent of the physical
+internet, and which may span multiple Autonomous Systems.  This capability
+is intended for experimental support of internet multicasting only, pending
+widespread support for multicast routing by the regular (unicast) routers.
+.Nm Mrouted
+suffers from the well-known scaling problems of any distance-vector
+routing protocol, and does not (yet) support hierarchical multicast routing.
+.Pp
+.Nm Mrouted
+handles multicast routing only; there may or may not be unicast routing
+software running on the same machine as
+.Nm .
+With the use of tunnels, it
+is not necessary for
+.Nm
+to have access to more than one physical subnet
+in order to perform multicast forwarding.
+.Pp
+The following options are available:
+.Bl -tag -width indent
+.It Fl c Ar config_file
+Specify an alternative file for configuration commands.
+Default is
+.Pa /etc/mrouted.conf .
+.It Fl d Op Ar debug_level
+If no
+.Fl d
+option is given, or if the debug level is specified as 0,
+.Nm
+detaches from the invoking terminal.  Otherwise, it remains attached to the
+invoking terminal and responsive to signals from that terminal.
+Regardless of the debug level,
+.Nm
+always writes warning and error messages to the system
+log daemon.  The
+.Fl debug-level
+argument is a comma-separated list of any of the following:
+.Bl -tag -width indent
+.It "packet"
+Display the type, source and destination of all packets sent or received.
+.It "pruning"
+Display more information about prunes sent or received.
+.It "routing"
+Display more information about routing update packets sent or received.
+.It "route_detail"
+Display routing updates in excruciating detail.  This is generally way too
+much information.
+.It "neighbors"
+Display information about neighbor discovery.
+.It "cache"
+Display insertions, deletions and refreshes of entries in
+the kernel forwarding cache.
+.It "timeout"
+Debug timeouts and periodic processes.
+.It "interface"
+Display information about interfaces and their configuration.
+.It "membership"
+Display information about group memberships on physical interfaces.
+.It "traceroute"
+Display information about multicast traceroute requests
+passing through this router.
+.It "igmp"
+Display IGMP operation including group membership and querier election.
+.It "icmp"
+Monitor ICMP handling.
+.It "rsrr"
+Monitor RSRR operation.
+.El
+.Pp
+Upon startup,
+.Nm
+writes its pid to the file
+.Pa /var/run/mrouted.pid .
+.El
+.Sh CONFIGURATION
+.Nm Mrouted
+automatically configures itself to forward on all multicast-capable
+interfaces, i.e., interfaces that have the IFF_MULTICAST flag set (excluding
+the loopback "interface"), and it finds other DVMRP routers directly reachable
+via those interfaces.  To override the default configuration, or to add
+tunnel links to other multicast routers,
+configuration commands may be placed in
+.Pa /etc/mrouted.conf
+(or an alternative file, specified by the
+.Fl c
+option).
+.Pp
+The file format is free-form; whitespace (including newlines) is not
+significant.
+The file begins with commands that apply to
+.Nm Ns 's
+overall operation or set defaults.
+.Bl -tag -width indent
+.It cache_lifetime Ar secs
+Specifies, in seconds, the lifetime of a multicast forwarding cache
+entry in the kernel.  Multicast forwarding cache entries in the kernel
+are checked every
+.Ar secs
+seconds, and are refreshed if the source is still
+active or deleted if not.  Care should be taken when setting this value,
+as a low value can keep the kernel cache small at the cost of "thrashing"
+the cache for periodic senders, but high values can cause the kernel
+cache to grow unacceptably large.  The default is 300 seconds (5 minutes).
+.It prune_lifetime Ar secs
+Sepcifies, in seconds, the average lifetime of prunes that are sent towards
+parents.  The actual lifetimes will be randomized in the range
+[.5\fIsecs\fP,1.5\fIsecs\fP].  The default is 7200 (2 hours).  Smaller values
+cause less state to be kept both at this router and the parent, at the
+cost of more frequent broadcasts.  However, some routers (e.g.\&
+.Nm
+<3.3
+and all currently known versions of cisco's IOS) do not use the
+DVMRP generation ID to determine that a neighbor has rebooted.  Prunes
+sent towards these neighbors should be kept short, in order to shorten
+the time to recover from a reboot.  For use in this situation, the
+prune_lifetime keyword may be specified on an interface as described
+below.
+.It noflood
+.Nm Mrouted
+uses a DVMRP optimization to prevent having to keep individual routing tables
+for each neighbor; part of this optimization is that
+.Nm
+assumes that it is the forwarder for each of its attached subnets on
+startup.  This can cause duplicates for a short period (approximately
+one full route report interval), since both the router that just
+started up and the proper forwarder will be forwarding traffic.  This
+behavior can be turned off with the noflood keyword;
+.Nm
+will not assume that it is the forwarder on startup.
+Turning on noflood can cause black holes on restart, which will generally
+last approximately one full route report interval.
+The noflood keyword can also be specified on individual interfaces.
+.It rexmit_prunes Ar [on|off]
+.Nm Mrouted Ns 's
+default is to retransmit prunes on all point-to-point interfaces
+(including tunnels) but no multi-access interfaces.  This option
+may be used to make the default on (or off) for all interfaces.
+The rexmit_prunes keyword can also be specified on individual interfaces.
+.It name Ar "boundary-name scoped-addr/mask-len"
+Associates
+.Ar boundary-name
+with the boundary described by
+.Ar scoped-addr/mask-len ,
+to help make interface configurations
+more readable and reduce repetition in the configuration file.
+.El
+.Pp
+The second section of the configuration file, which may optionally
+be empty, describes options that apply to physical interfaces.
+.Bl -tag -width indent
+.It phyint Ar "local-addr|ifname"
+The phyint command does nothing by itself; it is simply a place holder
+which interface-specific commands may follow.  An interface address or
+name may be specified.
+.It disable
+Disables multicast forwarding on this interface.  By default,
+.Nm
+discovers all locally attached multicast capable interfaces and forwards
+on all of them.
+.It netmask Ar netmask
+If the kernel's netmask does not accurately reflect
+the subnet (e.g. you're using proxy-ARP in lieu of IP subnetting), use the
+netmask command to describe the real netmask.
+.It altnet Ar network/mask-len
+If a phyint is attached to multiple IP subnets, describe each additional subnet
+with the altnet keyword.  This command may be specified multiple times
+to describe multiple subnets.
+.It igmpv1
+If there are any IGMPv1 routers on the phyint, use the \fBigmpv1\fP
+keyword to force
+.Nm
+into IGMPv1 mode.  All routers on the phyint
+must use the same version of IGMP.
+.It force_leaf
+Force
+.Nm
+to ignore other routers on this interface.
+.Nm
+will never send or accept neighbor probes or
+route reports on this interface.
+.El
+.Pp
+In addition, the common vif commands described later may all be used on
+a phyint.
+.Pp
+The third section of the configuration file, also optional, describes
+the configuration of any DVMRP tunnels this router might have.
+.Bl -tag -width indent
+.It tunnel Ar "local-addr|ifname" Ar "remote-addr|remote-hostname"
+This command establishes a DVMRP tunnel between this host (on the interface
+described by
+.Ar local-addr
+or
+.Ar ifname )
+and a remote host (identified by
+.Ar remote-addr
+or
+.Ar remote-hostname ) .
+A remote hostname may only be used if
+it maps to a single IP address.
+A tunnel must be configured on both routers before it can be used.
+.Pp
+Be careful that the unicast route to the remote address goes out the
+interface specified by the
+.Ar "local-addr|ifname"
+argument.  Some UNIX
+kernels rewrite the source address of
+.Nm Ns 's
+packets on their way out to contain the address of the transmission
+interface.  This is best assured via a static host route.
+.El
+.Pp
+The common vif commands described below
+may all be used on tunnels or phyints.
+.Bl -tag -width indent
+.It metric Ar m
+The metric is the "cost" associated with receiving a datagram on the given
+interface or tunnel; it may be used to influence the choice of routes.
+The metric defaults to 1.  Metrics should be kept as small as possible,
+because DVMRP cannot route along paths with a sum of metrics greater
+than 31.
+.It advert_metric Ar m
+The advert_metric is the "cost" associated with sending a datagram
+on the given interface or tunnel; it may be used to influence the choice
+of routes.  The advert_metric defaults to 0.  Note that the effective
+metric of a link is one end's metric plus the other end's advert_metric.
+.It threshold Ar t
+The threshold is the minimum IP time-to-live required for a multicast datagram
+to be forwarded to the given interface or tunnel.  It is used to control the
+scope of multicast datagrams.  (The TTL of forwarded packets is only compared
+to the threshold, it is not decremented by the threshold.  Every multicast
+router decrements the TTL by exactly 1.)  The default threshold is 1.
+.Pp
+In general, all multicast routers
+connected to a particular subnet or tunnel should
+use the same metric and threshold for that subnet or tunnel.
+.It rate_limit Ar r
+The rate_limit option allows the network administrator to specify a
+certain bandwidth in Kbits/second which would be allocated to multicast
+traffic.  It defaults 0 (unlimited).
+.It boundary Ar "boundary-name|scoped-addr/mask-len"
+The boundary option allows an interface
+to be configured as an administrative boundary for the specified
+scoped address.
+Packets belonging to this address will not
+be forwarded on a scoped interface.  The boundary option accepts either
+a name or a boundary spec.  This command may be specified several times
+on an interface in order to describe multiple boundaries.
+.It passive
+No packets will be sent on this link or tunnel until we hear from the other
+end.  This is useful for the "server" end of a tunnel that goes over
+a dial-on-demand link; configure the "server" end as passive and
+it will not send its periodic probes until it hears one from the other
+side, so will not keep the link up.  If this option is specified on both
+ends of a tunnel, the tunnel will never come up.
+.It noflood
+As described above, but only applicable to this interface/tunnel.
+.It prune_lifetime Ar secs
+As described above, but only applicable to this interface/tunnel.
+.It rexmit_prunes Ar "[on|off]"
+As described above, but only applicable to this interface/tunnel.
+Recall that prune retransmission
+defaults to on on point-to-point links and tunnels, and off on
+multi-access links.
+.It allow_nonpruners
+By default,
+.Nm
+refuses to peer with DVMRP neighbors that
+do not claim to support pruning.  This option allows such peerings
+on this interface.
+.It notransit
+A specialized case of route filtering; no route learned from an interface
+marked "notransit" will be advertised on another interface marked
+"notransit".  Marking only a single interface "notransit" has no meaning.
+.It accept|deny Ar "(route/mask-len [exact])+" Op bidir
+The
+.Li accept
+and
+.Li deny
+commands allow rudimentary route filtering.  The
+.Li accept
+command causes
+.Nm
+to accept only the listed routes on the configured interface; the
+.Li deny
+command causes
+.Nm
+to accept all but the listed routes.
+Only one of
+.Li accept
+or
+.Li deny
+commands may be used on a given interface.
+.Pp
+The list of routes follows the
+.Li accept
+or
+.Li deny
+keyword.  If the keyword
+.Ar exact
+follows a route, then only that route is matched; otherwise, that route
+and any more specific route is matched.  For example,
+.Li deny 0/0
+denys all routes, while
+.Li deny 0/0 exact
+denys only the default route.  The default route may also be specified
+with the
+.Li default
+keyword.
+.Pp
+The
+.Ar bidir
+keyword enables bidirectional route filtering; the filter will be applied
+to routes on both output and input.  Without the
+.Ar bidir
+keyword,
+.Li accept
+and
+.Li deny
+filters are only applied on input.  Poison reverse routes are never
+filtered out.
+.El
+.Pp
+.Nm Mrouted
+will not initiate execution if it has fewer than two enabled vifs,
+where a vif (virtual interface) is either a physical multicast-capable
+interface or a tunnel.  It will log a warning if all of its vifs are
+tunnels; such an
+.Nm
+configuration would be better replaced by more
+direct tunnels (i.e. eliminate the middle man).
+.Sh "EXAMPLE CONFIGURATION"

+In this example, there are four vifs connecting to two subnets and two
+tunnels.  The vif 3 tunnel is not in use (no peer address). The vif 0 and
+vif 1 subnets have some groups present; tunnels never have any groups.  This
+instance of
+.Nm
+is the one responsible for sending periodic group
+membership queries on the vif 0 and vif 1 subnets, as indicated by the
+"querier" flags.
+The list of boundaries indicate the scoped addresses on that
+interface.
+A count of the no. of incoming and outgoing packets is also
+shown at each interface.
+.Pp
+Associated with each subnet from which a multicast datagram can originate
+is the address of the previous hop router (unless the subnet is directly-
+connected), the metric of the path back to the origin, the amount of time
+since we last received an update for this subnet, the incoming vif for
+multicasts from that origin, and a list of outgoing vifs.  "*" means that
+the outgoing vif is connected to a leaf of the broadcast tree rooted at the
+origin, and a multicast datagram from that origin will be forwarded on that
+outgoing vif only if there are members of the destination group on that leaf.

+.Sh DESCRIPTION
+Assessing problems in the distribution of IP multicast traffic
+can be difficult.
+.Nm Mtrace
+utilizes a tracing feature implemented in multicast routers that is
+accessed via an extension to the IGMP protocol.  A trace query is
+passed hop-by-hop along the reverse path from the
+.Ar receiver
+to the
+.Ar source ,
+collecting hop addresses, packet counts, and routing error conditions
+along the path, and then the response is returned to the requestor.
+.Pp
+The only required parameter is the
+.Ar source
+host name or address.  The default
+.Ar receiver
+is the host running mtrace, and the default
+.Ar group
+is 0.0.0.0, which is sufficient if packet loss
+statistics for a particular multicast group are not needed.  These two
+optional parameters may be specified to test the path to some other
+receiver in a particular group, subject to some constraints as
+detailed below.  The two parameters can be distinguished because the
+.Ar receiver
+is a unicast address and the
+.Ar group
+is a multicast address.
+If the
+.Fl g
+flag is specified, the source address defaults to the host running
+.Nm ,
+and the receiver defaults to the router being addressed with
+the
+.Fl g
+flag.  In this case, there are no required parameters.
+.Pp
+NOTE: For Solaris 2.4/2.5, if the multicast interface is not the default
+interface, the
+.Fl i
+option must be used to set the local address.
+.Pp
+The following options are available:
+.Bl -tag -width indent
+.It Fl e Ar extrahops
+Try tracing
+.Ar extrahops
+hops past a non-responding router.
+.It Fl g Ar gwy
+Send the trace query via unicast directly to the multicast router
+.Ar gwy
+rather than multicasting the query.
+This must be the last-hop router on the path from the intended
+.Ar source
+to the
+.Ar receiver .
+.Pp
+.Em CAUTION ! !
+Versions 3.3 and 3.5 of
+.Nm mrouted
+will crash if a trace query is received via a
+unicast packet and
+.Nm mrouted
+has no route for the
+.Ar source
+address.  Therefore, do not use the
+.Fl g
+option unless the target
+.Nm mrouted
+has been verified to be 3.4 or newer than 3.5.
+.It Fl i Ar addr
+Use
+.Ar addr
+as the local interface address (on a multi-homed host) for sending the
+trace query and as the default for the
+.Ar receiver
+and the response destination.
+.It Fl l
+Loop indefinitely printing packet rate and loss statistics for the
+multicast path every 10 seconds (see
+.Fl S Ar stat_int ) .
+.It Fl M
+Always request the response using multicast rather than attempting
+unicast for the last half of the tries.
+.It Fl m Ar n
+Set to
+.Ar n
+the maximum number of hops that will be traced from the
+.Ar receiver
+back toward the
+.Ar source .
+The default is 32 hops (infinity for the DVMRP routing protocol).
+.It Fl n
+Print hop addresses numerically rather than symbolically and numerically
+(saves a nameserver address-to-name lookup for each router found on the
+path).
+.It Fl q Ar n
+Set the maximum number of query attempts for any hop to
+.Ar n .
+The default is 3.
+.It Fl O
+Do not use the Router-Alert IP option on those requests which need it.
+Some versions of Cisco's IOS cannot handle
+multicast traceroutes with IP options, so it may be necessary to use the
+.Fl O
+flag if the last-hop router is a Cisco.
+.It Fl p
+Listen passively for multicast responses from traces initiated by
+others.  This works best when run on a multicast router.
+.It Fl P
+Loop indefinitely collecting the path every 10 seconds (see
+.Fl S Ar stat_int )
+and printing it when it changes.  Do not print any statistics.
+.It Fl r Ar host
+Send the trace response to
+.Ar host
+rather than to the host on which
+.Nm
+is being run, or to a multicast address other than the one registered
+for this purpose (224.0.1.32).
+.It Fl s
+Print a short form output including only the multicast path and not
+the packet rate and loss statistics.
+.It Fl S Ar n
+Change the interval between statistics gathering traces to
+.Ar n
+seconds (default 10 seconds).
+.It Fl t Ar ttl
+Set the
+.Ar ttl
+(time-to-live, or number of hops) for multicast trace queries and
+responses.  The default is 127, except for local queries to the "all
+routers" multicast group which use ttl 1.
+.It Fl T
+"Tunnel statistics" mode; show loss rates for overall traffic.
+These statistics can be extremely misleading.
+.It Fl U
+Always request the response using unicast rather than attempting
+multicast first.
+.It Fl v
+Verbose mode; show hop times on the initial trace and statistics display.
+Also show the route that was used to forward the initial trace.
+.It Fl w Ar n
+Set the time to wait for a trace response to
+.Ar n
+seconds (default 3 seconds).
+.El
+.Sh USAGE
+.Ss "How It Works"
+The technique used by the
+.Nm traceroute
+tool to trace unicast network paths will not work for IP multicast
+because ICMP responses are specifically forbidden for multicast traffic.
+Instead, a tracing feature has been built into the multicast routers.
+This technique has the advantage that additional information about
+packet rates and losses can be accumulated while the number of packets
+sent is minimized.
+.Pp
+Since multicast uses
+reverse path forwarding, the trace is run backwards from the
+.Ar receiver
+to the
+.Ar source .
+A trace query packet is sent to the last
+hop multicast router (the leaf router for the desired
+.Ar receiver
+address).  The last hop router builds a trace response packet, fills in
+a report for its hop, and forwards the trace packet using unicast to
+the router it believes is the previous hop for packets originating
+from the specified
+.Ar source .
+Each router along the path adds its report and forwards the packet.
+When the trace response packet reaches the first hop router (the router
+that is directly connected to the source's net), that router sends the
+completed response to the response destination address specified in
+the trace query.
+.Pp
+If some multicast router along the path does not implement the
+multicast traceroute feature or if there is some outage, then no
+response will be returned.  To solve this problem, the trace query
+includes a maximum hop count field to limit the number of hops traced
+before the response is returned.  That allows a partial path to be
+traced.
+.Pp
+The reports inserted by each router contain not only the address of
+the hop, but also the ttl required to forward and some flags to indicate
+routing errors, plus counts of the total number of packets on the
+incoming and outgoing interfaces and those forwarded for the specified
+.Ar group .
+Taking differences in these counts for two traces separated in time
+and comparing the output packet counts from one hop with the input
+packet counts of the next hop allows the calculation of packet rate
+and packet loss statistics for each hop to isolate congestion
+problems.
+.Ss Finding the Last-Hop Router
+The trace query must be sent to the multicast router which is the
+last hop on the path from the
+.Ar source
+to the
+.Ar receiver .
+If the receiver is on the local subnet (as determined using the subnet
+mask), then the default method is to multicast the trace query to
+all-routers.mcast.net (224.0.0.2) with a ttl of 1.  Otherwise, the
+trace query is multicast to the
+.Ar group
+address since the last hop router will be a member of that group if
+the receiver is.  Therefore it is necessary to specify a group that
+the intended receiver has joined.  This multicast is sent with a
+default ttl of 127, which may not be sufficient for all cases (changed
+with the
+.Fl t
+option).
+If the last hop router is known, it may also be addressed directly
+using the
+.Fl g
+option).  Alternatively, if it is desired to trace a group that the
+receiver has not joined, but it is known that the last-hop router is a
+member of another group, the
+.Fl g
+option may also be used to specify a different multicast address for the
+trace query.
+.Pp
+When tracing from a multihomed host or router, the default receiver
+address may not be the desired interface for the path from the source.
+In that case, the desired interface should be specified explicitly as
+the
+.Ar receiver .
+.Ss Directing the Response
+By default,
+.Nm
+first attempts to trace the full reverse path, unless the number of
+hops to trace is explicitly set with the
+.Fl m
+option.  If there is no response within a 3 second timeout interval
+(changed with the
+.Fl w
+option), a "*" is printed and the probing switches to hop-by-hop mode.
+Trace queries are issued starting with a maximum hop count of one and
+increasing by one until the full path is traced or no response is
+received.  At each hop, multiple probes are sent (default is three,
+changed with
+.Fl q
+option).  The first half of the attempts (default is two) are made with
+the reply address set to standard multicast address, mtrace.mcast.net
+(224.0.1.32) with the ttl set to 32 more than what's needed to pass the
+thresholds seen so far along the path to the receiver.  For each
+additional attempt, the ttl is increased by another 32 each time up to
+a maximum of 192.  Since the desired router may not be able to send a
+multicast reply, the remainder of the attempts request that the
+response be sent via unicast to the host running
+.Nm .
+Alternatively, the multicast ttl may be set explicitly with the
+.Fl t
+option, the initial multicast attempts can be forced to use unicast
+instead with the
+.Fl U
+option, the final unicast attempts can be forced to use multicast
+isntead with the
+.Fl M
+option, or if you specify
+.Fl UM ,
+.Nm
+will first attempt using unicast and then multicast.  For each attempt,
+if no response is received within the timeout, a "*" is printed.  After
+the specified number of attempts have failed,
+.Nm
+will try to query the next hop router with a DVMRP_ASK_NEIGHBORS2
+request (as used by the
+.Nm mrinfo
+program) to see what kind of router it is.
+.Nm
+will try to query three (changed with the
+.Fl e
+option) hops past a non-responding router, in the hopes that even
+though it isn't capable of sending a response, it might be capable of
+forwarding the request on.
+.Sh EXAMPLES
+The output of
+.Nm
+is in two sections.  The first section is a short listing of the hops
+in the order they are queried, that is, in the reverse of the order
+from the
+.Ar source
+to the
+.Ar receiver .
+For each hop, a line is printed showing the hop number (counted
+negatively to indicate that this is the reverse path); the multicast
+routing protocol (DVMRP, MOSPF, PIM, etc.); the threshold required to
+forward data (to the previous hop in the listing as indicated by the
+up-arrow character); and the cumulative delay for the query to reach
+that hop (valid only if the clocks are synchronized).  This first
+section ends with a line showing the round-trip time which measures
+the interval from when the query is issued until the response is
+received, both derived from the local system clock, and the total
+ttl required for a packet to travel along this path.  A sample use and
+output might be:

+.Ed
+.Pp
+If a hop reports that it is using the default route to forward packets,
+the word
+.Em [default]
+is printed after that hop.  If the
+.Fl v
+flag is supplied, the route being used to forward packets is printed
+in the form
+.Em [18.26.0/24] .
+.Pp
+The second section provides a pictorial view of the path in the
+forward direction with data flow indicated by arrows pointing downward
+and the query path indicated by arrows pointing upward.  For each hop,
+both the entry and exit addresses of the router are shown if
+different, along with the initial ttl required on the packet in order
+to be forwarded at this hop and the propagation delay across the hop
+assuming that the routers at both ends have synchronized clocks.
+The right half of this section is composed of two sets of statistics.
+The first column contains the average packet rate for all traffic at
+each hop.
+The remaining columns are the
+number of packets lost, the number of packets sent, the percentage
+lost, and the average packet rate at each hop.  These statistics are
+calculated from differences between traces and from hop to hop as
+explained above.  The first group shows the statistics for all traffic
+flowing out the interface at one hop and in the interface at the next
+hop.  The second group shows the statistics only for traffic forwarded
+from the specified
+.Ar source
+to the specified
+.Ar group .
+The first group of statistics may be expanded to include loss rates
+using the
+.Fl T
+option.  However, these numbers can be extremely misleading and require
+detailed knowledge of the routers involved to be interpreted properly.
+.Pp
+These statistics are shown on one or two lines for each hop.  Without

+.Pp
+Because the packet counts may be changing as the trace query is
+propagating, there may be small errors (off by 1 or 2) in these
+statistics.  However, those errors should not accumulate, so the
+cumulative statistics line should increase in accuracy as a new trace
+is run every 10 seconds.  There are two sources of larger errors, both
+of which show up as negative losses:
+.Pp
+If the input to a node is from a multi-access network with more than
+one other node attached, then the input count will be (close to) the
+sum of the output counts from all the attached nodes, but the output
+count from the previous hop on the traced path will be only part of
+that.  Hence the output count minus the input count will be negative.
+.Pp
+In release 3.3 of the DVMRP multicast forwarding software for SunOS
+and other systems, a multicast packet generated on a router will be
+counted as having come in an interface even though it did not.  This
+creates the negative loss that can be seen in the example above.
+.Pp
+Note that these negative losses may mask positive losses.
+.Pp
+In the example, there is also one negative hop time.  This simply
+indicates a lack of synchronization between the system clocks across
+that hop.  This example also illustrates how the percentage loss is
+shown as two dashes when the number of packets sent is less than 10
+because the percentage would not be statistically valid.
+.Pp
+A second example shows a trace to a receiver that is not local; the
+query is sent to the last-hop router with the
+.Fl g
+option.  In this example, the trace of the full reverse path resulted
+in no response because there was a node running an old version of
+.Nm mrouted
+that did not implement the multicast traceroute function, so
+.Nm
+switched to hop-by-hop mode.  The
+.Dq Output pruned
+error code
+indicates that traffic for group 224.2.143.24 would not be forwarded.

+/*
+ * mtrace.c
+ *
+ * This tool traces the branch of a multicast tree from a source to a
+ * receiver for a particular multicast group and gives statistics
+ * about packet rate and loss for each hop along the path.  It can
+ * usually be invoked just as
+ *
+ * 	mtrace source
+ *
+ * to trace the route from that source to the local host for a default
+ * group when only the route is desired and not group-specific packet
+ * counts.  See the usage line for more complex forms.
+ *
+ *
+ * Released 4 Apr 1995.  This program was adapted by Steve Casner
+ * (USC/ISI) from a prototype written by Ajit Thyagarajan (UDel and
+ * Xerox PARC).  It attempts to parallel in command syntax and output
+ * format the unicast traceroute program written by Van Jacobson (LBL)
+ * for the parts where that makes sense.

+.Sh DESCRIPTION
+.Nm
+is a small program for testing the multicast membership socket operations
+and ioctls.  It accepts the following commands, interactively:
+.Bl -tag -width "a ifname e.e.e.e.e.e" -compact -offset indent
+.It Ic j Ar g.g.g.g Ar i.i.i.i
+Join the IP group address
+.Ar g.g.g.g
+on the interface with address
+.Ar i.i.i.i .
+.Ar i.i.i.i
+may be specified as 0.0.0.0 to use the default interface.
+.It Ic l Ar g.g.g.g Ar i.i.i.i
+Leave the IP group address
+.Ar g.g.g.g
+on the interface with address
+.Ar i.i.i.i .
+.It Ic a Ar ifname Ar e.e.e.e.e.e
+Join the Ethernet group address
+.Ar e.e.e.e.e.e
+on interface
+.Ar ifname .
+.It Ic d Ar ifname Ar e.e.e.e.e.e
+Leave the Ethernet group address
+.Ar e.e.e.e.e.e
+on interface
+.Ar ifname .
+.It Ic m Ar ifname Ar 1/0
+Set or reset ALLMULTI mode on interface
+.Ar ifname .
+.It Ic p Ar ifname Ar 1/0
+Set or reset promiscuous mode on interface
+.Ar ifname .
+.It Ic ?\&
+List legal commands.
+.It Ic q
+Quit the program.

+.Sh DESCRIPTION
+The utility
+.Nm
+compares the file hierarchy rooted in the current directory against a
+specification read from the standard input.
+Messages are written to the standard output for any files whose
+characteristics do not match the specifications, or which are
+missing from either the file hierarchy or the specification.
+.Pp
+The options are as follows:
+.Bl -tag -width flag
+.It Fl L
+Follow all symbolic links in the file hierarchy.
+.It Fl P
+Don't follow symbolic links in the file hierarchy, instead consider
+the symbolic link itself in any comparisons. This is the default.
+.It Fl U
+Modify the owner, group and permissions of existing files to match
+the specification and create any missing directories or symbolic links.
+User, group and permissions must all be specified for missing directories
+to be created.
+Corrected mismatches are not considered errors.
+.It Fl c
+Print a specification for the file hierarchy to the standard output.
+.It Fl d
+Ignore everything except directory type files.
+.It Fl e
+Don't complain about files that are in the file hierarchy, but not in the
+specification.
+.It Fl i
+Indent the output 4 spaces each time a directory level is descended when
+create a specification with the
+.Fl c
+option.
+This does not affect either the /set statements or the comment before each
+directory.
+It does however affect the comment before the close of each directory.
+.It Fl n
+Do not emit pathname comments when creating a specification.  Normally
+a comment is emitted before each directory and before the close of that
+directory when using the
+.Fl c
+option.
+.It Fl q
+Quiet mode.  Do not complain when a
+.Dq missing
+directory cannot be created because it already exists.
+This occurs when the directory is a symbolic link.
+.It Fl r
+Remove any files in the file hierarchy that are not described in the
+specification.
+.It Fl u
+Same as
+.Fl U
+except a status of 2 is returned if the file hierarchy did not match
+the specification.
+.It Fl x
+Don't descend below mount points in the file hierarchy.
+.It Fl f Ar file
+Read the specification from
+.Ar file  ,
+instead of from the standard input.
+.It Fl K Ar keywords
+Add the specified (whitespace or comma separated)
+.Ar keywords
+to the current set of keywords.
+.It Fl k Ar keywords
+Use the ``type'' keyword plus the specified (whitespace or comma separated)
+.Ar keywords
+instead of the current set of keywords.
+.It Fl p Ar path
+Use the file hierarchy rooted in
+.Ar path  ,
+instead of the current directory.
+.It Fl s Ar seed
+Display a single checksum to the standard error output that represents all
+of the files for which the keyword
+.Cm cksum
+was specified.
+The checksum is seeded with the specified value.
+.It Fl X Ar exclude-list
+The specified file contains
+.Xr fnmatch 3
+patterns matching files to be excluded from
+the specification, one to a line.
+If the pattern contains a
+.Ql \&/
+character, it will be matched against entire pathnames (relative to
+the starting directory); otherwise,
+it will be matched against basenames only.  No comments are allowed in
+the
+.Ar exclude-list
+file.
+.El
+.Pp
+Specifications are mostly composed of ``keywords'', i.e. strings that
+that specify values relating to files.
+No keywords have default values, and if a keyword has no value set, no
+checks based on it are performed.
+.Pp
+Currently supported keywords are as follows:
+.Bl -tag -width Cm
+.It Cm cksum
+The checksum of the file using the default algorithm specified by
+the
+.Xr cksum 1
+utility.
+.It Cm flags
+The file flags as a symbolic name.  See
+.Xr chflags 1
+for information on these names.  If no flags are to be set the string
+.Dq none
+may be used to override the current default.
+.It Cm ignore
+Ignore any file hierarchy below this file.
+.It Cm gid
+The file group as a numeric value.
+.It Cm gname
+The file group as a symbolic name.
+.It Cm md5digest
+The MD5 message digest of the file.
+.It Cm sha1digest
+The
+.Tn FIPS
+160-1
+.Pq Dq Tn SHA-1
+message digest of the file.
+.It Cm ripemd160digest
+The
+.Tn RIPEMD160
+message digest of the file.
+.It Cm mode
+The current file's permissions as a numeric (octal) or symbolic
+value.
+.It Cm nlink
+The number of hard links the file is expected to have.
+.It Cm nochange
+Make sure this file or directory exists but otherwise ignore all attributes.
+.It Cm uid
+The file owner as a numeric value.
+.It Cm uname
+The file owner as a symbolic name.
+.It Cm size
+The size, in bytes, of the file.
+.It Cm link
+The file the symbolic link is expected to reference.
+.It Cm time
+The last modification time of the file.
+.It Cm type
+The type of the file; may be set to any one of the following:
+.Pp
+.Bl -tag -width Cm -compact
+.It Cm block
+block special device
+.It Cm char
+character special device
+.It Cm dir
+directory
+.It Cm fifo
+fifo
+.It Cm file
+regular file
+.It Cm link
+symbolic link
+.It Cm socket
+socket
+.El
+.El
+.Pp
+The default set of keywords are
+.Cm flags ,
+.Cm gid ,
+.Cm mode ,
+.Cm nlink ,
+.Cm size ,
+.Cm link ,
+.Cm time ,
+and
+.Cm uid .
+.Pp
+There are four types of lines in a specification.
+.Pp
+The first type of line sets a global value for a keyword, and consists of
+the string ``/set'' followed by whitespace, followed by sets of keyword/value
+pairs, separated by whitespace.
+Keyword/value pairs consist of a keyword, followed by an equals sign
+(``=''), followed by a value, without whitespace characters.
+Once a keyword has been set, its value remains unchanged until either
+reset or unset.
+.Pp
+The second type of line unsets keywords and consists of the string
+``/unset'', followed by whitespace, followed by one or more keywords,
+separated by whitespace.
+.Pp
+The third type of line is a file specification and consists of a file
+name, followed by whitespace, followed by zero or more whitespace
+separated keyword/value pairs.
+The file name may be preceded by whitespace characters.
+The file name may contain any of the standard file name matching
+characters (``['', ``]'', ``?'' or ``*''), in which case files
+in the hierarchy will be associated with the first pattern that
+they match.
+.Pp
+Each of the keyword/value pairs consist of a keyword, followed by an
+equals sign (``=''), followed by the keyword's value, without
+whitespace characters.
+These values override, without changing, the global value of the
+corresponding keyword.
+.Pp
+All paths are relative.
+Specifying a directory will cause subsequent files to be searched
+for in that directory hierarchy.
+Which brings us to the last type of line in a specification: a line
+containing only the string
+.Dq Pa ..\&
+causes the current directory
+path to ascend one level.
+.Pp
+Empty lines and lines whose first non-whitespace character is a hash
+mark (``#'') are ignored.
+.Pp
+The
+.Nm
+utility exits with a status of 0 on success, 1 if any error occurred,
+and 2 if the file hierarchy did not match the specification.
+A status of 2 is converted to a status of 0 if the
+.Fl U
+option is used.
+.Sh EXAMPLES
+To detect system binaries that have been ``trojan horsed'', it is recommended
+that
+.Nm
+.Fl K
+.Cm sha1digest
+be run on the filesystems, and a copy of the results stored on a different
+machine, or, at least, in encrypted form.
+The output file itself should be digested using the
+.Xr md5 1
+utility.
+Then, periodically,
+.Nm
+and
+.Xr md5 1
+should be run against the on-line specifications.
+While it is possible for the bad guys to change the on-line specifications
+to conform to their modified binaries, it is believed to be
+impractical for them to create a modified specification which has
+the same MD5 digest as the original.
+.Pp
+The
+.Fl d
+and
+.Fl u
+options can be used in combination to create directory hierarchies
+for distributions and other such things; the files in
+.Pa /etc/mtree
+were used to create almost all directories in this
+.Fx
+distribution.

+The

+utility appeared in

+The
+.Tn MD5
+digest capability was added in

+which restarts the running name server with the command line options

+.Xr rc.conf 5 .
+.Sh BUGS
+Does not wait after killing the old server before starting a new one; since
+the server could take some time to die and the new one will experience a
+fatal error if the old one isn't gone by the time it starts, you can be left
+in a situation where you have no name server at all.

+.Sh DESCRIPTION
+The
+.Nm
+command manipulates the address mapping table
+used by Neighbor Discovery Protocol (NDP).
+.Bl -tag -width Ds
+.It Fl a
+Dump the currently existing NDP entries.
+.It Fl A Ar wait
+Repeat
+.Fl a
+(dump NDP entries)
+every
+.Ar wait
+seconds.
+.It Fl c
+Erase all the NDP entries.
+.It Fl d
+Delete specified NDP entry.
+.It Fl f
+Parse the file specified by
+.Ar filename .
+.It Fl H
+Harmonize consistency between the routing table and the default router
+list; install the top entry of the list into the kernel routing table.
+.It Fl I Op Cm delete | Ar interface
+Shows or specifies the default interface used as the default route when
+there is no default router.
+If no argument is given to the option,
+the current default interface will be shown.
+If an
+.Ar interface
+is specified, the interface will be used as the default.
+If a special keyword
+.Ic delete
+is specified, the current default interface will be deleted from the kernel.
+.It Fl i Ar interface Op Ar flags...
+View ND information for the specified interface.
+If additional arguments
+.Ar flags
+are given,
+.Nm
+sets or clears the specified flags for the interface.
+Possible flags are as follows.
+All of the flags can begin with the
+special character
+.Ql - ,
+which means the flag should be cleared.
+.\"
+.Bl -tag -width Ds -compact
+.It Xo
+.Ic nud
+.Xc
+turn on or off NUD (Neighbor Unreachability Detection) on the
+interface.
+NUD is usually turned on by default.
+.El
+.It Fl n
+Do not try to resolve numeric address to hostname.
+.It Fl p
+Show prefix list.
+.It Fl P
+Flush all the entries in the prefix list.
+.It Fl r
+Show default router list.
+.It Fl R
+Flush all the entries in the default router list.
+.It Fl s
+Register an NDP entry for a node.
+The entry will be permanent unless the word
+.Li temp
+is given in the command.
+If the word
+.Li proxy
+is given, this system will act as an proxy NDP server,
+responding to requests for
+.Ar hostname
+even though the host address is not its own.
+.It Fl t
+Print timestamp on each entries,
+to make it possible to merge output with
+.Xr tcpdump 1 .
+Most useful when used with
+.Fl A .

+.Os
+.Sh NAME
+.Nm newsyslog
+.Nd maintain system log files to manageable sizes
+.Sh SYNOPSIS
+.Nm
+.Op Fl Fnrv
+.Op Fl f Ar config_file
+.Op Fl a Ar directory
+.Op Ar
+.Sh DESCRIPTION
+.Nm Newsyslog
+is a program that should be scheduled to run periodically by
+.Xr cron 8 .
+When it is executed it archives log files if necessary.  If a log file
+is determined to require archiving,
+.Nm
+rearranges the files so that
+.Dq Va logfile
+is empty,
+.Dq Va logfile Ns Li \&.0
+has
+the last period's logs in it,
+.Dq Va logfile Ns Li \&.1
+has the next to last
+period's logs in it, and so on, up to a user-specified number of
+archived logs.  Optionally the archived logs can be compressed to save
+space.
+.Pp
+A log can be archived for three reasons:
+.Bl -enum -offset indent
+.It
+It is larger than the configured size (in kilobytes).
+.It
+A configured number of hours have elapsed since the log was last
+archived.
+.It
+This is the specific configured hour for rotation of the log.
+.El
+.Pp
+The granularity of
+.Nm
+is dependent on how often it is scheduled to run by
+.Xr cron 8 .
+Since the program is quite fast, it may be scheduled to run every hour
+without any ill effects,
+and mode three (above) assumes that this is so.
+.Pp
+When starting up,
+.Nm
+reads in a configuration file to determine which logs may potentially
+be archived.
+By default, this configuration file is
+.Pa /etc/newsyslog.conf .
+Each line of the file contains information about a particular log file
+that should be handled by
+.Nm .
+Each line has five mandatory fields and four optional fields, with
+whitespace separating each field.  Blank lines or lines beginning with
+``#'' are ignored.  The fields of the configuration file are as
+follows:
+.Pp
+.Bl -tag -width indent
+.It Ar logfile_name
+Name of the system log file to be archived.
+.It Ar owner : Ns Ar group
+This optional field specifies the owner and group for the archive file.
+The ":" is essential, even if the
+.Ar owner
+or
+.Ar group
+field is left blank.  The field may be numeric, or a name which is
+present in
+.Pa /etc/passwd
+or
+.Pa /etc/group .
+.It Ar mode
+Specify the mode of the log file and archives.
+.It Ar count
+Specify the number of archive files to be kept
+besides the log file itself.
+.It Ar size
+When the size of the log file reaches
+.Ar size
+in kilobytes,
+the log file will be trimmed as described above.  If this field
+is replaced by an asterisk
+.Pq Ql \&* ,
+then the size of the log file is not taken into account
+when determining when to trim the log file.
+.It Ar when
+The
+.Ar when
+field can consist of an interval, a specific time, or both.  If
+the
+.Ar when
+field is an asterisk
+.Pq Ql \&*
+log rotation will depend only on the contents of the
+.Ar size
+field.
+Otherwise, the
+.Ar when
+field consists of an optional interval in hours, optionally followed
+by an
+.So Li \&@ Sc Ns No -sign
+and a time in a restricted
+.Tn ISO 8601
+format or by an
+.So Li \&$ Sc Ns No -sign
+and a time specification for logfile rotation at a fixed time once
+per day, per week or per month.
+.Pp
+If a time is specified, the log file will only be trimmed if
+.Nm
+is run within one hour of the specified time.  If an
+interval is specified, the log file will be trimmed if that many hours have
+passed since the last rotation.  When both a time and an interval are
+specified, both conditions must be satisfied for the rotation to take
+place.
+.Pp
+There is no provision for specification of a timezone.  There is
+little point in specifying an explicit minutes or seconds component in
+the current implementation, since the only comparison is `within the
+hour'.
+.Pp
+.Sy ISO 8601 restricted time format
+.Pp
+The lead-in character for a restricted
+.Tn ISO 8601
+time is
+an
+.So Li \&@ Sc Ns No -sign .
+The particular format of the time in restricted
+.Tn ISO 8601
+is:
+.Sm off
+.Oo
+.Oo
+.Oo
+.Oo
+.Oo
+.Va \&cc
+.Oc
+.Va \&yy
+.Oc
+.Va \&mm
+.Oc
+.Va \&dd
+.Oc
+.Oo
+.Li \&T
+.Oo
+.Va \&hh
+.Oo
+.Va \&mm
+.Oo
+.Va \&ss
+.Oc
+.Oc
+.Oc
+.Oc
+.Oc .
+.Sm on
+Optional date fields default to the appropriate component of the
+current date; optional time fields default to midnight; hence if today
+is January 22, 1999, the following date specifications are all
+equivalent:
+.Pp
+.Bl -item -compact -offset indent

+.Sq Li 19990122T000000

+.Sq Li 22T
+.It
+.Sq Li \&T
+.It
+.Sq Li \&
+.El
+.Pp
+.Sy Day, week and month time format
+.Pp
+The lead-in character for day, week and month specification is a
+.So Li \&$ Sc Ns No -sign .
+The particular format of day, week and month specification is:
+.Op Va D\&hh ,
+.Op Va W\&w Ns Op Va D\&hh
+and
+.Op Va M\&dd Ns Op Va D\&hh
+respectively.
+Optional time fields default to midnight.
+The ranges for day and hour secifications are:
+.Pp
+.Bl -tag -width Ds -compact -offset indent
+.It Ar hh
+hours, range 0 ... 23
+.It Ar w
+day of week, range 0 ... 6, 0 = Sunday
+.It Ar dd
+day of month, range 1 ... 31, or the letter
+.Em L
+or
+.Em l
+to specify the last day of the month.
+.El
+.Pp
+Some examples:
+.Pp
+.Bl -tag -width Ds -compact -offset indent
+.It Ar $D0
+rotate every night at midnight
+(same as
+.Ar @T00 )
+.It Ar $D23
+rotate every day at 23:00 hr
+(same as
+.Ar @T23 )
+.It Ar $W0D23
+rotate every week on Sunday at 23:00 hr
+.It Ar $W5D16
+rotate every week on Friday at 16:00 hr
+.It Ar $M1D0
+rotate at the first day of every month at midnight
+(i.e., the start of the day; same as
+.Ar @01T00 )
+.It Ar $M5D6
+rotate on every 5th day of month at 6:00 hr
+(same as
+.Ar @05T06 )
+.El
+.Pp
+.It Ar flags
+This optional field specifies if the archive should have any
+special processing done to the archived log files.
+The
+.Ar Z
+flag will make the archive files compress to save space by
+using
+.Xr gzip 1 .
+The
+.Ar J
+flag will make the archive files compress to save space by
+using
+.Xr bzip2 1 .
+The
+.Ar B
+flag means that the file is a binary file, and so the
+.Tn ASCII
+message which
+.Nm
+inserts to indicate the fact that the logs have been
+turned over should not be included.  The
+.Ar -
+flag means nothing, but can be used as a placeholder when the
+.Ar path_to_pid_file
+field is specified.
+.It Ar path_to_pid_file
+This optional field specifies
+the file name to read to find the daemon process id.  If this
+field is present, a
+.Ar signal_number
+is sent the process id contained in this
+file.  This field must start with "/" in order to be recognized
+properly.
+.It Ar signal_number
+This optional field specifies
+the signal number will be sent to the daemon process.
+By default
+a SIGHUP will be sent.
+.El
+.Sh OPTIONS
+The following options can be used with
+.Nm :
+.Bl -tag -width indent
+.It Fl f Ar config_file
+Instruct
+.Nm
+to use
+.Ar config_file
+instead of
+.Pa /etc/newsyslog.conf
+for its configuration file.
+.It Fl a Ar directory
+Specify a
+.Ar directory
+into which archived log files will be written.
+If a relative path is given,
+it is appended to the path of each log file
+and the resulting path is used as the directory
+into which the archived log for that log file will be written.
+If an absolute path is given,
+all archived logs are written into the given
+.Ar directory .
+If any component of the path
+.Ar directory
+does not exist,
+it will be created when
+.Nm
+is run.
+.It Fl v
+Place
+.Nm
+in verbose mode.  In this mode it will print out each log and its
+reasons for either trimming that log or skipping it.
+.It Fl n
+Cause
+.Nm
+not to trim the logs, but to print out what it would do if this option
+were not specified.
+.It Fl r
+Remove the restriction that
+.Nm
+must be running as root.  Of course,
+.Nm
+will not be able to send a HUP signal to
+.Xr syslogd 8
+so this option should only be used in debugging.
+.It Fl F
+Force
+.Nm
+to trim the logs, even if the trim conditions have not been met.  This
+option is useful for diagnosing system problems by providing you with
+fresh logs that contain only the problems.
+.El
+.Pp
+If additional command line arguments are given,
+.Nm
+will only examine log files that match those arguments; otherwise, it
+will examine all files listed in the configuration file.
+.Sh FILES
+.Bl -tag -width /etc/newsyslog.confxxxx -compact
+.It Pa /etc/newsyslog.conf
+.Nm
+configuration file
+.El
+.Sh BUGS
+Doesn't yet automatically read the logs to find security breaches.

+.Sh COMPATIBILITY
+Previous versions of the
+.Nm
+utility used the dot (``.'') character to
+distinguish the group name.
+Begining with
+.Fx 3.3 ,
+this has been changed to a colon (``:'') character so that user and group
+names may contain the dot character.  The dot (``.'') character is still
+accepted for backwards compatibility.

+.Sh NAME
+.Nm nfsd
+.Nd remote
+.Tn NFS
+server
+.Sh SYNOPSIS
+.Nm
+.Op Fl ardut
+.Op Fl n Ar num_servers
+.Op Fl h Ar bindip
+.Sh DESCRIPTION
+The
+.Nm
+utility runs on a server machine to service
+.Tn NFS
+requests from client machines.
+At least one
+.Nm
+must be running for a machine to operate as a server.
+.Pp
+Unless otherwise specified, four servers for
+.Tn UDP
+transport are started.
+.Pp
+The following options are available:
+.Bl -tag -width Ds
+.It Fl r
+Register the
+.Tn NFS
+service with
+.Xr rpcbind 8
+without creating any servers.
+This option can be used along with the
+.Fl u
+or
+.Fl t
+options to re-register NFS if the rpcbind server is restarted.
+.It Fl d
+Unregister the
+.Tn NFS
+service with
+.Xr rpcbind 8
+without creating any servers.
+.It Fl n
+Specifies how many servers to create.
+.It Fl h Ar bindip
+Specifies which IP address or hostname to bind to on the local host.
+This option is recommended when a host has multiple interfaces.
+Multiple
+.Fl h
+options may be specified.
+.It Fl a
+Specifies that nfsd should bind to the wildcard IP address.
+This is the default if no
+.Fl h
+options are given.  It may also be specified in addition to any
+.Fl h
+options given.  Note that NFS/UDP does not operate properly when
+bound to the wildcard IP address whether you use -a or do not use -h.
+.It Fl t
+Serve
+.Tn TCP NFS
+clients.
+.It Fl u
+Serve
+.Tn UDP NFS
+clients.
+.El
+.Pp
+For example,
+.Dq Li "nfsd -u -t -n 6"
+serves
+.Tn UDP
+and
+.Tn TCP
+transports using six daemons.
+.Pp
+A server should run enough daemons to handle
+the maximum level of concurrency from its clients,
+typically four to six.
+.Pp
+The
+.Nm
+utility listens for service requests at the port indicated in the
+.Tn NFS
+server specification; see
+.%T "Network File System Protocol Specification" ,
+RFC1094 and
+.%T "NFS: Network File System Version 3 Protocol Specification" .
+.Pp
+If
+.Nm
+detects that
+.Tn NFS
+is not loaded in the running kernel, it will attempt
+to load a loadable kernel module containing
+.Tn NFS
+support using
+.Xr kldload 8
+by way of
+.Xr vfsload 3 .
+If this fails, or no
+.Tn NFS
+KLD is available,
+.Nm
+will exit with an error.
+.Pp
+If
+.Nm
+is to be run on a host with multiple interfaces or interface aliases, use
+of the
+.Fl h
+option is recommended.  If you do not use the option NFS may not respond to
+UDP packets from the same IP address they were sent to.  Use of this option
+is also recommended when securing NFS exports on a firewalling machine such
+that the NFS sockets can only be accessed by the inside interface.
+The
+.Nm ipfw
+utility
+would then be used to block nfs-related packets that come in on the outside
+interface.
+.Pp
+The
+.Nm
+utility has to be terminated with
+.Dv SIGUSR1
+and cannot be killed with
+.Dv SIGTERM
+or
+.Dv SIGQUIT .
+The
+.Nm
+utility needs to ignore these signals in order to stay alive as long
+as possible during a shutdown, otherwise loopback mounts will
+not be able to unmount.
+If you have to kill
+.Nm
+just do a
+.Dq Li "kill -USR1 <PID of master nfsd>"

+.Sh NAME
+.Nm ngctl
+.Nd netgraph control utility
+.Sh SYNOPSIS
+.Nm
+.Op Fl d
+.Op Fl f Ar filename
+.Op Fl n Ar nodename
+.Op Ar command ...
+.Sh DESCRIPTION
+The
+.Nm
+utility creates a new netgraph node of type
+.Em socket
+which can be used to issue netgraph commands.
+If no
+.Fl f
+flag is given, no
+command is supplied on the command line, and standard input is a tty,
+.Nm
+will enter interactive mode.
+Otherwise
+.Nm
+will execute the supplied command(s) and exit immediately.
+.Pp
+Nodes can be created, removed, joined together, etc.
+.Tn ASCII
+formatted control messages can be sent to any node if that node
+supports binary/ASCII control message conversion.
+.Pp
+In interactive mode,
+.Nm
+will display any control messages and data packets received by the socket node.
+In the case of control messages, the message arguments are displayed in
+.Tn ASCII
+form if the originating node supports conversion.
+.Pp
+The options are as follows:
+.Bl -tag -width indent
+.It Fl f Ar nodeinfo
+Read commands from the named file.
+A single dash represents the standard input.
+Blank lines and lines starting with a
+.Dq #
+are ignored.
+.It Fl n Ar nodename
+Assign
+.Em nodename
+to the newly created netgraph node.
+The default name is
+.Em ngctlXXX
+where XXX is the process ID number.
+.It Fl d
+Increase the debugging verbosity level.
+.El
+.Sh COMMANDS
+The currently supported commands in
+.Nm
+are:
+.Pp
+.Bd -literal -offset indent -compact
+connect    Connects two nodes
+debug      Get/set debugging verbosity level
+help       Show command summary or get help on a command
+list       Show information about all nodes
+mkpeer     Create and connect a new node to an existing node
+msg        Send an ASCII formatted message to a node
+name       Assign a name to a node
+read       Read and execute commands from a file
+rmhook     Disconnect a node's hook
+show       Show information about a node
+shutdown   Shutdown a node
+status     Get human readable status from a node
+types      Show all installed node types
+write      Send a data packet down the hook named by "hook".
+quit       Exit program
+.Ed
+.Pp
+Some commands have aliases, e.g.,
+.Dq ls
+is the same as
+.Dq list .
+The
+.Dq help
+command displays the available
+commands, their usage and aliases, and a brief description.

+.Sh NAME
+.Nm nghook
+.Nd connect to a
+.Xr netgraph 4
+node
+.Sh SYNOPSIS
+.Nm
+.Op Fl a
+.Op Fl d
+.Op Fl l
+.Op Fl n
+.Ar path
+.Op Ar hookname
+.Sh DESCRIPTION
+.Nm
+creates a
+.Xr ng_socket 4
+socket type node and connects it to hook
+.Ar hookname
+of the node found at
+.Ar path .
+If
+.Ar hookname
+is omitted,
+.Dq debug
+is assumed.
+.Pp
+At this point all data written to standard input is sent
+to the node and all data received from the node is relayed
+to standard output.
+.Nm
+exits when
+.Dv EOF
+is detected on standard input.
+.Pp
+The options are as follows:
+.Pp
+.Bl -tag -width indent
+.It Fl a
+Output each packet read in human-readable decoded
+.Tn ASCII
+form instead of raw binary.
+.It Fl d
+Increase the debugging verbosity level.
+.It Fl l
+Loops all received data back to the hook in addition to writing it
+to standard output.
+.It Fl n
+Don't attempt to read any data from standard input.
+.Nm
+will continue reading from the node until stopped by a signal.
+.El
+.Sh BUGS
+Although all input is read in unbuffered mode,
+there's no way to control the packetization of the input.
+.Sh SEE ALSO
+.Xr netgraph 3 ,
+.Xr netgraph 4 ,
+.Xr ngctl 8
+.Sh HISTORY
+The
+.Em netgraph
+system was designed and first implemented at Whistle Communications, Inc.\&
+in a version of
+.Fx 2.2
+customized for the Whistle InterJet.

+.Sh SYNOPSIS
+.Nm
+.Op Fl dfhlnt
+.Op Fl c Ar conffile
+.Op Fl g Ar target
+.Op Fl k Ar keyfile
+.Sh DESCRIPTION
+This program generates random keys used by either or both the
+NTPv3/NTPv4 symmetric key or the NTPv4 public key (Autokey)
+cryptographic authentication schemes.
+.Pp
+The following options are available:
+.Bl -tag -width indent
+.It Fl c Ar conffile
+Location of
+.Xr ntp.conf 8
+file.
+.It Fl d
+enable debug messages (can be used multiple times)
+.It Fl f
+force installation of generated keys.
+.It Fl g target
+Generate file or files indicated by the characters in the
+.Ar target
+string:
+.Bl -tag -width X
+.It Li d 
+Generate D-H parameter file.
+.It Li m
+Generate MD5 key file.
+.It Li r
+Generate RSA keys.
+.El
+.It Fl h
+Build keys here (current directory).
+Implies
+.Fl l .
+.It Fl k Ar keyfile
+Location of key file.
+.It Fl l
+Do not make the symlinks.
+.It Fl n
+Do not actually do anything, just say what would be done.
+.It Fl t
+Trash the (old) files at the end of symlink.
+.El
+.Pp
+By default the program
+generates the
+.Xr ntp.keys 5
+file containing 16 random symmetric
+keys.
+In addition, if the
+rsaref20
+package is configured
+for the software build, the program generates cryptographic values
+used by the Autokey scheme.
+These values are incorporated as a set
+of three files,
+.Pa ntpkey
+containing the RSA private key,
+.Pa ntpkey_ Ns Ar host
+containing the RSA public key, where
+.Ar host
+is the DNS name of the generating machine, and
+.Pa ntpkey_dh
+containing the parameters for the Diffie-Hellman
+key-agreement algorithm.
+All files and are in printable ASCII
+format.
+A timestamp in NTP seconds is appended to each.
+Since the
+algorithms are seeded by the system clock, each run of this program
+produces a different file and file name.
+.Pp
+The
+.Xr ntp.keys 5
+file contains 16 MD5 keys.
+Each key
+consists of 16 characters randomized over the ASCII 95-character
+printing subset.
+The file is read by the daemon at the location
+specified by the
+.Ic keys
+configuration file command and made
+visible only to root.
+An additional key consisting of a easily
+remembered password should be added by hand for use with the
+.Xr ntpq 8
+and
+.Xr ntpdc 8
+programs.
+The file must be
+distributed by secure means to other servers and clients sharing
+the same security compartment.
+While the key identifiers for MD5
+and DES keys must be in the range 1-65534, inclusive, the
+.Nm
+program uses only the identifiers from 1 to
+16.
+The key identifier for each association is specified as the key
+argument in the
+.Ic server
+or
+.Ic peer
+configuration file command.
+.Pp
+The
+.Pa ntpkey
+file contains the RSA private key.
+It is
+read by the daemon at the location specified by the
+.Ar privatekey
+argument of the
+.Ic crypto
+configuration
+file command and made visible only to root.
+This file is useful
+only to the machine that generated it and never shared with any
+other daemon or application program.
+.Pp
+The
+.Pa ntpkey_ Ns Ar host
+file contains the RSA public
+key, where
+.Ar host
+is the DNS name of the host that
+generated it.
+The file is read by the daemon at the location
+specified by the
+.Ar publickey
+argument to the
+.Ic server
+or
+.Ic peer
+configuration file command.
+This file can be
+widely distributed and stored without using secure means, since the
+data are public values.
+.Pp
+The
+.Pa ntp_dh
+file contains two Diffie-Hellman parameters:
+the prime modulus and the generator.
+The file is read by the daemon
+at the location specified by the
+.Ar dhparams
+argument of the
+.Ic crypto
+configuration file command.
+The file can be
+distributed by insecure means to other servers and clients sharing
+the same key agreement compartment, since the data are public
+values.
+.Pp
+The file formats begin with two lines, the first containing the
+generating system DNS name and the second the datestamp.
+Lines
+beginning with
+.Ql #
+are considered comments and ignored by
+the daemon.
+In the 
+.Xr ntp.keys 5
+file, the next 16 lines
+contain the MD5 keys in order.
+If necessary, this file can be
+further customized by an ordinary text editor.
+The format is
+described in the following section.
+In the
+.Pa ntpkey
+and
+.Pa ntpkey_ Ns Ar host
+files, the next line contains the
+modulus length in bits followed by the key as a PEM encoded string.
+In the
+.Pa ntpkey_dh
+file, the next line contains the prime
+length in bytes followed by the prime as a PEM encoded string, and
+the next and final line contains the generator length in bytes
+followed by the generator as a PEM encoded string.
+.Pp
+Note: See the file
+.Pa ./source/rsaref.h
+in the
+rsaref20
+package for explanation of return values, if
+necessary.

+.Sh NAME
+.Nm ntp.conf
+.Nd Network Time Protocol (NTP) daemon configuration file
+.Sh SYNOPSIS
+.Nm /etc/ntp.conf
+.Sh DESCRIPTION
+The
+.Nm
+configuration file is read at initial startup by the
+.Xr ntpd 8
+daemon in order to specify the synchronization sources,
+modes and other related information.
+Usually, it is installed in the
+.Pa /etc
+directory,
+but could be installed elsewhere
+(see the daemon's
+.Fl c
+command line option).
+.Pp
+The file format is similar to other
+.Ux
+configuration files.
+Comments begin with a
+.Ql #
+character and extend to the end of the line;
+blank lines are ignored.
+Configuration commands consist of an initial keyword
+followed by a list of arguments,
+some of which may be optional, separated by whitespace.
+Commands may not be continued over multiple lines.
+Arguments may be host names,
+host addresses written in numeric, dotted-quad form,
+integers, floating point numbers (when specifying times in seconds)
+and text strings.
+.Pp
+The rest of this page describes the configuration and control options.
+The
+.Qq "Notes on Configuring NTP and Setting up a NTP Subnet"
+page
+(available as part of the HTML documentation
+provided in
+.Pa /usr/share/doc/ntp )
+contains an extended discussion of these options.
+In addition to the discussion of general
+.Sx Configuration Options ,
+there are sections describing the following supported functionality
+and the options used to control it:

+Following these is a section describing
+.Sx Miscellaneous Options .
+While there is a rich set of options available,
+the only required option is one or more
+.Ic server ,
+.Ic peer ,
+.Ic broadcast
+or
+.Ic manycastclient
+commands.
+.Sh Configuration Support
+Following is a description of the configuration commands in
+NTPv4.
+These commands have the same basic functions as in NTPv3 and
+in some cases new functions and new arguments.
+There are two
+classes of commands, configuration commands that configure a
+persistent association with a remote server or peer or reference
+clock, and auxilliary commands that specify environmental variables
+that control various related operations.
+.Ss Configuration Commands
+The various modes are determined by the command keyword and the
+type of the required IP address.
+Addresses are classed by type as
+(s) a remote server or peer (IP class A, B and C), (b) the
+broadcast address of a local interface, (m) a multicast address (IP
+class D), or (r) a reference clock address (127.127.x.x).
+Note that
+only those options applicable to each command are listed below.
+Use
+of options not listed may not be caught as an error, but may result
+in some weird and even destructive behavior.

+These four commands specify the time server name or address to
+be used and the mode in which to operate.
+The
+.Ar address
+can be
+either a DNS name or a IP address in dotted-quad notation.

+.Qq "Association Management"
+page.
+.Bl -tag -width indent
+.It Ic server
+For type s and r addresses, this command mobilizes a persistent
+client mode association with the specified remote server or local
+radio clock.
+In this mode the local clock can synchronized to the
+remote server, but the remote server can never be synchronized to
+the local clock.
+This command should
+.Em not
+be used for type
+b or m addresses.
+.It Ic peer
+For type s addresses (only), this command mobilizes a
+persistent symmetric-active mode association with the specified
+remote peer.
+In this mode the local clock can be synchronized to
+the remote peer or the remote peer can be synchronized to the local
+clock.
+This is useful in a network of servers where, depending on
+various failure scenarios, either the local or remote peer may be
+the better source of time.
+This command should NOT be used for type
+b, m or r addresses.
+.It Ic broadcast
+For type b and m addresses (only), this
+command mobilizes a persistent broadcast mode association.
+Multiple
+commands can be used to specify multiple local broadcast interfaces
+(subnets) and/or multiple multicast groups.
+Note that local
+broadcast messages go only to the interface associated with the
+subnet specified, but multicast messages go to all interfaces.
+In broadcast mode the local server sends periodic broadcast
+messages to a client population at the
+.Ar address
+specified, which is usually the broadcast address on (one of) the
+local network(s) or a multicast address assigned to NTP.
+The IANA
+has assigned the multicast group address 224.0.1.1 exclusively to
+NTP, but other nonconflicting addresses can be used to contain the
+messages within administrative boundaries.
+Ordinarily, this
+specification applies only to the local server operating as a
+sender; for operation as a broadcast client, see the
+.Ic broadcastclient
+or
+.Ic multicastclient
+commands
+below.
+.It Ic manycastclient
+For type m addresses (only), this command mobilizes a
+manycast client mode association for the multicast address
+specified.
+In this case a specific address must be supplied which
+matches the address used on the
+.Ic manycastserver
+command for
+the designated manycast servers.
+The NTP multicast address
+224.0.1.1 assigned by the IANA should NOT be used, unless specific
+means are taken to avoid spraying large areas of the Internet with
+these messages and causing a possibly massive implosion of replies
+at the sender.
+The
+.Ic manycastserver
+command specifies that the local server
+is to operate in client mode with the remote servers that are
+discovered as the result of broadcast/multicast messages.
+The
+client broadcasts a request message to the group address associated
+with the specified
+.Ar address
+and specifically enabled
+servers respond to these messages.
+The client selects the servers
+providing the best time and continues as with the
+.Ic server
+command.
+The remaining servers are discarded as if never
+heard.
+.El
+.Pp
+Options:
+.Bl -tag -width indent
+.It Cm autokey
+All packets sent to and received from the server or peer are to
+include authentication fields encrypted using the autokey scheme
+described in
+.Sx Authentication Options .
+.It Cm burst
+when the server is reachable and at each poll interval, send a
+burst of eight packets instead of the usual one packet.
+The spacing
+between the first and the second packets is about 16s to allow a
+modem call to complete, while the spacing between the remaining
+packets is about 2s.
+This is designed to improve timekeeping
+quality with the
+.Ic server
+command and s
+addresses.
+.It Cm iburst
+When the server is unreachable and at each poll interval, send
+a burst of eight packets instead of the usual one.
+As long as the
+server is unreachable, the spacing between packets is about 16s to
+allow a modem call to complete.
+Once the server is reachable, the
+spacing between packets is about 2s.
+This is designed to speed the
+initial synchronization acquisition with the
+.Ic server
+command and s addresses and when
+.Xr ntpd 8
+is started
+with the
+.Fl q
+option.
+.It Cm key Ar key
+All packets sent to and received from the server or peer are to
+include authentication fields encrypted using the specified
+.Ar key
+identifier with values from 1 to 65534, inclusive.
+The
+default is to include no encryption field.
+.It Cm minpoll Ar minpoll
+.It Cm maxpoll Ar maxpoll
+These options specify the minimum and maximum poll intervals
+for NTP messages, in seconds to the power of two.
+The maximum poll
+interval defaults to 10 (1,024 s), but can be increased by the
+.Cm maxpoll
+option to an upper limit of 17 (36.4 h).
+The
+minimum poll interval defaults to 6 (64 s), but can be decreased by
+the
+.Cm minpoll
+option to a lower limit of 4 (16 s).
+.It Cm prefer
+Marks the server as preferred.
+All other things being equal,
+this host will be chosen for synchronization among a set of
+correctly operating hosts.
+See the
+.Qq "Mitigation Rules and the prefer Keyword"
+page for further
+information.
+.It Cm ttl Ar ttl
+This option is used only with broadcast server and manycast
+client modes.
+It specifies the time-to-live
+.Cm ttl
+to
+use on broadcast server and multicast server and the maximum
+.Cm ttl
+for the expanding ring search with manycast
+client packets.
+Selection of the proper value, which defaults to
+127, is something of a black art and should be coordinated with the
+network administrator.
+.It Cm version Ar version
+Specifies the version number to be used for outgoing NTP
+packets.
+Versions 1-4 are the choices, with version 4 the
+default.
+.El
+.Ss Auxilliary Commands
+.Bl -tag -width indent
+.It Ic broadcastclient
+This command enables reception of broadcast server messages to
+any local interface (type b) address.
+Upon receiving a message for
+the first time, the broadcast client measures the nominal server
+propagation delay using a brief client/server exchange with the
+server, then enters the broadcast client mode, in which it
+synchronizes to succeeding broadcast messages.
+Note that, in order
+to avoid accidental or malicious disruption in this mode, both the
+server and client should operate using symmetric-key or public-key
+authentication as described in
+.Sx Authentication Options .
+.It Ic manycastserver Ar address ...
+This command enables reception of manycast client messages to
+the multicast group address(es) (type m) specified.
+At least one
+address is required, but the NTP multicast address 224.0.1.1
+assigned by the IANA should NOT be used, unless specific means are
+taken to limit the span of the reply and avoid a possibly massive
+implosion at the original sender.
+Note that, in order to avoid
+accidental or malicious disruption in this mode, both the server
+and client should operate using symmetric-key or public-key
+authentication as described in
+.Sx Authentication Options .
+.It Ic multicastclient Ar address ...
+This command enables reception of multicast server messages to
+the multicast group address(es) (type m) specified.
+Upon receiving
+a message for the first time, the multicast client measures the
+nominal server propagation delay using a brief client/server
+exchange with the server, then enters the broadcast client mode, in
+which it synchronizes to succeeding multicast messages.
+Note that,
+in order to avoid accidental or malicious disruption in this mode,
+both the server and client should operate using symmetric-key or
+public-key authentication as described in
+.Sx Authentication Options .
+.El
+.Sh Authentication Support
+Authentication support allows the NTP client to verify that the
+server is in fact known and trusted and not an intruder intending
+accidentally or on purpose to masquerade as that server.
+The NTPv3
+specification RFC-1305 defines an scheme which provides
+cryptographic authentication of received NTP packets.
+Originally,
+this was done using the Data Encryption Standard (DES) algorithm
+operating in Cipher Block Chaining (CBC) mode, commonly called
+DES-CBC.
+Subsequently, this was augmented by the RSA Message Digest
+5 (MD5) algorithm using a private key, commonly called keyed-MD5.
+Either algorithm computes a message digest, or one-way hash, which
+can be used to verify the server has the correct private key and
+key identifier.
+.Pp
+NTPv4 retains the NTPv3 schemes, properly described as
+symmetric-key cryptography and, in addition, provides a new Autokey
+scheme based on public-key cryptography.
+Public-key cryptography is
+generally considered more secure than symmetric-key cryptography,
+since the security is based on a private value which is generated
+by each server and never revealed.
+With Autokey all key
+distribution and management functions involve only public values,
+which considerably simplifies key distribution and storage.
+.Pp
+Authentication is configured separately for each association
+using the
+.Cm key
+or
+.Cm autokey
+subcommands on the
+.Ic peer  ,
+.Ic server  ,
+.Ic broadcast
+and
+.Ic manycastclient
+commands as described in
+.Sx Configuration Options .
+The authentication
+options described below specify the suite of keys, select the key
+for each configured association and manage the configuration
+operations.
+.Pp
+The
+.Cm auth
+flag controls whether new associations or
+remote configuration commands require cryptographic authentication.
+This flag can be set or reset by the
+.Ic enable
+and
+.Ic disable
+configuration commands and also by remote
+configuration commands sent by a
+.Xr ntpdc 8
+program running in
+another machine.
+If this flag is enabled, which is the default
+case, new broadcast client and symmetric passive associations and
+remote configuration commands must be cryptographically
+authenticated using either symmetric-key or public-key schemes.
+If
+this flag is disabled, these operations are effective even if not
+cryptographic authenticated.
+It should be understood that operating
+in the latter mode invites a significant vulnerability where a
+rogue hacker can seriously disrupt client timekeeping.
+.Pp
+In networks with firewalls and large numbers of broadcast
+clients it may be acceptable to disable authentication, since that
+avoids key distribution and simplifies network maintenance.
+However, when the configuration file contains host names, or when a
+server or client is configured remotely, host names are resolved
+using the DNS and a separate name resolution process.
+In order to
+protect against bogus name server messages, name resolution
+messages are authenticated using an internally generated key which
+is normally invisible to the user.
+However, if cryptographic
+support is disabled, the name resolution process will fail.
+This
+can be avoided either by specifying IP addresses instead of host
+names, which is generally inadvisable, or by enabling the flag for
+name resolution and disabled it once the name resolution process is
+complete.
+.Pp
+An attractive alternative where multicast support is available
+is manycast mode, in which clients periodically troll for servers.
+Cryptographic authentication in this mode uses public-key schemes
+as described below.
+The principle advantage of this manycast mode
+is that potential servers need not be configured in advance, since
+the client finds them during regular operation, and the
+configuration files for all clients can be identical.
+.Pp
+In addition to the default symmetric-key cryptographic support,
+support for public-key cryptography is available if the requisite
+.Sy rsaref20
+software distribution has been installed before
+building the distribution.
+Public-key cryptography provides secure
+authentication of servers without compromising accuracy and
+stability.
+The security model and protocol schemes for both
+symmetric-key and public-key cryptography are described below.
+.Ss Symmetric-Key Scheme
+The original RFC-1305 specification allows any one of possibly
+65,534 keys, each distinguished by a 32-bit key identifier, to
+authenticate an association.
+The servers and clients involved must
+agree on the key and key identifier to authenticate their messages.
+Keys and related information are specified in a key file, usually
+called
+.Pa ntp.keys  ,
+which should be exchanged and stored
+using secure procedures beyond the scope of the NTP protocol
+itself.
+Besides the keys used for ordinary NTP associations,
+additional keys can be used as passwords for the
+.Xr ntpq 8
+and
+.Xr ntpdc 8
+utility programs.
+.Pp
+When
+.Xr ntpd 8
+is first started, it reads the key file
+specified in the
+.Ic keys
+command and installs the keys in the
+key cache.
+However, the keys must be activated with the
+.Ic trusted
+command before use.
+This allows, for instance, the
+installation of possibly several batches of keys and then
+activating or deactivating each batch remotely using
+.Xr ntpdc 8  .
+This also provides a revocation capability that can
+be used if a key becomes compromised.
+The
+.Ic requestkey
+command selects the key used as the password for the
+.Xr ntpdc 8
+utility, while the
+.Ic controlkey
+command selects the key used
+as the password for the
+.Xr ntpq 8
+utility.
+.Ss Public-Key Scheme
+The original NTPv3 authentication scheme described in RFC-1305
+continues to be supported; however, in NTPv4 an additional
+authentication scheme called Autokey is available.
+It uses MD5
+message digest, RSA public-key signature and Diffie-Hellman key
+agreement algorithms available from several sources, but not
+included in the NTPv4 software distribution.
+In order to be
+effective, the
+.Sy rsaref20
+package must be installed as
+described in the
+.Pa README.rsa
+file.
+Once installed, the
+configure and build process automatically detects it and compiles
+the routines required.
+The Autokey scheme has several modes of
+operation corresponding to the various NTP modes supported.
+RSA
+signatures with timestamps are used in all modes to verify the
+source of cryptographic values.
+All modes use a special cookie
+which can be computed independently by the client and server.
+In
+symmetric modes the cookie is constructed using the Diffie-Hellman
+key agreement algorithm.
+In other modes the cookie is constructed
+from the IP addresses and a private value known only to the server.
+All modes use in addition a variant of the S-KEY scheme, in which a
+pseudo-random key list is generated and used in reverse order.
+These schemes are described along with an executive summary,
+current status, briefing slides and reading list, in the
+.Qq "Autonomous Authentication"
+page.
+.Pp
+The cryptographic values used by the Autokey scheme are
+incorporated as a set of files generated by the
+.Xr ntp-genkeys 8
+program, including the
+symmetric private keys, public/private key pair, and the agreement
+parameters.
+See the
+.Xr ntp.keys 5
+page for a description of
+the formats of these files.
+They contain cryptographic values
+generated by the algorithms of the
+.Sy rsaref20
+package and
+are in printable ASCII format.
+All file names include the
+timestamp, in NTP seconds, following the default names given below.
+Since the file data are derived from random values seeded by the
+system clock and the file name includes the timestamp, every
+generation produces a different file and different file name.
+.Pp
+The
+.Pa ntp.keys
+file contains the DES/MD5 private keys.
+It
+must be distributed by secure means to other servers and clients
+sharing the same security compartment and made visible only to
+root.
+While this file is not used with the Autokey scheme, it is
+needed to authenticate some remote configuration commands used by
+the
+.Xr ntpdc 8 ,
+.Xr ntpq 8
+utilities.
+The
+.Pa ntpkey
+file
+contains the RSA private key.
+It is useful only to the machine that
+generated it and never shared with any other daemon or application
+program, so must be made visible only to root.
+.Pp
+The
+.Pa ntp_dh
+file contains the agreement parameters,
+which are used only in symmetric (active and passive) modes.
+It is
+necessary that both peers beginning a symmetric-mode association
+share the same parameters, but it does not matter which
+.Pa ntp_dh
+file generates them.
+If one of the peers contains
+the parameters, the other peer obtains them using the Autokey
+protocol.
+If both peers contain the parameters, the most recent
+copy is used by both peers.
+If a peer does not have the parameters,
+they will be requested by all associations, either configured or
+not; but, none of the associations can proceed until one of them
+has received the parameters.
+Once loaded, the parameters can be
+provided on request to other clients and servers.
+The
+.Pa ntp_dh
+file can be also be distributed using insecure
+means, since the data are public values.
+.Pp
+The
+.Pa ntpkey_ Ns Ar host
+file contains the RSA public
+key, where
+.Ar host
+is the name of the host.
+Each host
+must have its own
+.Pa ntpkey_ Ns Ar host
+file, which is
+normally provided to other hosts using the Autokey protocol.
+Each
+.Ic server
+or
+.Ic peer
+association requires the public
+key associated with the particular server or peer to be loaded
+either directly from a local file or indirectly from the server
+using the Autokey protocol.
+These files can be widely distributed
+and stored using insecure means, since the data are public
+values.
+.Pp
+The optional
+.Pa ntpkey_certif_ Ns Ar host
+file contains
+the PKI certificate for the host.
+This provides a binding between
+the host hame and RSA public key.
+In the current implementation the
+certificate is obtained by a client, if present, but the contents
+are ignored.
+.Pp
+Due to the widespread use of interface-specific naming, the host
+names used in configured and mobilized associations are determined
+by the
+.Ux
+.Xr gethostname 3
+library routine.
+Both the
+.Xr ntp-genkeys 8
+program and the Autokey protocol derive the
+name of the public key file using the name returned by this
+routine.
+While every server and client is required to load their
+own public and private keys, the public keys for each client or
+peer association can be obtained from the server or peer using the
+Autokey protocol.
+Note however, that at the current stage of
+development the authenticity of the server or peer and the
+cryptographic binding of the server name, address and public key is
+not yet established by a certificate authority or web of trust.
+.Ss Leapseconds Table
+The NIST provides a table showing the epoch for all historic
+occasions of leap second insertion since 1972.
+The leapsecond table
+shows each epoch of insertion along with the offset of
+International Atomic Time (TAI) with respect to Coordinated
+Universtal Time (UTC), as disseminated by NTP.
+The table can be
+obtained directly from NIST national time servers using
+FTP as the ASCII file
+.Pa pub/leap-seconds .
+.Pp
+While not strictly a security function, the Autokey scheme
+provides means to securely retrieve the leapsecond table from a
+server or peer.
+Servers load the leapsecond table directly from the
+file specified in the
+.Ic crypto
+command, while clients can
+load the table indirectly from the servers using the Autokey
+protocol.
+Once loaded, the table can be provided on request to
+other clients and servers.
+.Ss Key Management
+All key files are installed by default in
+.Pa /usr/local/etc ,
+which is normally in a shared filesystem
+in NFS-mounted networks and avoids installing them in each machine
+separately.
+The default can be overridden by the
+.Ic keysdir   
+configuration command.
+However, this is not a good place to install
+the private key file, since each machine needs its own file.
+A
+suitable place to install it is in
+.Pa /etc ,
+which is normally
+not in a shared filesystem.
+.Pp
+The recommended practice is to keep the timestamp extensions
+when installing a file and to install a link from the default name
+(without the timestamp extension) to the actual file.
+This allows
+new file generations to be activated simply by changing the link.
+However,
+.Xr ntpd 8
+parses the link name when present to extract
+the extension value and sends it along with the public key and host
+name when requested.
+This allows clients to verify that the file
+and generation time are always current.
+However, the actual
+location of each file can be overridden by the
+.Ic crypto
+configuration command.
+.Pp
+All cryptographic keys and related parameters should be
+regenerated on a periodic and automatic basis, like once per month.
+The
+.Xr ntp-genkeys 8
+program uses the same timestamp extension
+for all files generated at one time, so each generation is distinct
+and can be readily recognized in monitoring data.
+While a
+public/private key pair must be generated by every server and
+client, the public keys and agreement parameters do not need to be
+explicitly copied to all machines in the same security compartment,
+since they can be obtained automatically using the Autokey
+protocol.
+However, it is necessary that all primary servers have
+the same agreement parameter file.
+The recommended way to do this
+is for one of the primary servers to generate that file and then
+copy it to the other primary servers in the same compartment using
+the
+.Ux
+.Xr rdist 1
+command.
+Future versions of the Autokey
+protocol are to contain provisions for an agreement protocol to do
+this automatically.
+.Pp
+Servers and clients can make a new generation in the following
+way.
+All machines have loaded the old generation at startup and are
+operating normally.
+At designated intervals, each machine generates
+a new public/private key pair and makes links from the default file
+names to the new file names.
+The
+.Xr ntpd 8
+is then restarted
+and loads the new generation, with result clients no longer can
+authenticate correctly.
+The Autokey protocol is designed so that
+after a few minutes the clients time out and restart the protocol
+from the beginning, with result the new generation is loaded and
+operation continues as before.
+A similar procedure can be used for
+the agreement parameter file, but in this case precautions must be
+take to be sure that all machines with this file have the same
+copy.
+.Ss Authentication Commands

+These values need to be updated frequently in order to
+deflect brute-force attacks on the algorithms of the scheme;
+however, updating some values is a relatively expensive operation.
+The default interval is 16 (65,536 s or about 18 hours).
+For poll

+.Bl -tag -width indent
+.It Ar name
+This is the type of the statistics records, as shown in the

+.It Cm file Ar filename
+This is the file name for the statistics records.
+Filenames of
+set members are built from three concatenated elements
+prefix, filename and
+suffix:
+.Bl -tag -width indent
+.It prefix
+This is a constant filename path.
+It is not subject to
+modifications via the
+.Ic filegen   
+option.
+It is defined by the
+server, usually specified as a compile-time constant.
+It may,
+however, be configurable for individual file generation sets via
+other commands.
+For example, the prefix used with
+.Cm loopstats   
+and
+.Cm peerstats   
+generation can be
+configured using the
+.Ic statsdir   
+option explained above.
+.It filename
+This string is directly concatenated to the prefix mentioned
+above (no intervening
+.Ql /
+(slash)).
+This can be modified
+using the
+.Ar file
+argument to the
+.Ic filegen   
+statement.
+No
+.Ql \&..
+elements are allowed in this component to prevent
+filenames referring to parts outside the filesystem hierarchy
+denoted by prefix.
+.It suffix
+This part is reflects individual elements of a file set.
+It is
+generated according to the type of a file set.
+.El
+.It Cm type Ar typename
+A file generation set is characterized by its type.
+The
+following types are supported:
+.Bl -tag -width indent
+.It none
+The file set is actually a single plain file.
+.It pid
+One element of file set is used per incarnation of a
+.Xr ntpd 8   
+server.
+This type does not perform any changes to
+file set members during runtime, however it provides an easy way of
+separating files belonging to different
+.Xr ntpd 8   
+server
+incarnations.
+The set member filename is built by appending a
+.Ql \&.
+(dot) to concatenated prefix and filename
+strings, and appending the decimal representation of the process ID
+of the
+.Xr ntpd 8   
+server process.
+.It day
+One file generation set element is created per day.
+A day is
+defined as the period between 00:00 and 24:00 UTC.
+The file set
+member suffix consists of a
+.Ql \&.
+(dot) and a day
+specification in the form
+.Ar YYYYMMdd .
+.Ar YYYY
+is a 4-digit year
+number (e.g., 1992).
+.Ar MM
+is a two digit month number.
+.Ar dd
+is a two digit day number.
+Thus, all information
+written at 10 December 1992 would end up in a file named
+.Sm off
+.Pa Ar prefix / Ar filename / 19921210 .
+.Sm on
+.It week
+Any file set member contains data related to a certain week of
+a year.
+The term week is defined by computing day-of-year modulo 7.
+Elements of such a file generation set are distinguished by
+appending the following suffix to the file set filename base: A
+dot, a 4-digit year number, the letter
+Ql W ,
+and a 2-digit
+week number.
+For example, information from January, 10th 1992 would
+end up in a file with suffix
+.Pa .1992W1 .
+.It month
+One generation file set element is generated per month.
+The
+file name suffix consists of a dot, a 4-digit year number, and a
+2-digit month.
+.It year
+One generation file element is generated per year.
+The filename
+suffix consists of a dot and a 4 digit year number.
+.It age
+This type of file generation sets changes to a new element of
+the file set every 24 hours of server operation.
+The filename
+suffix consists of a dot, the letter
+.Ql a ,
+and an 8-digit
+number.
+This number is taken to be the number of seconds the server
+is running at the start of the corresponding 24-hour period.
+Information is only written to a file generation by specifying
+.Ic enable  ; 
+output is prevented by specifying
+.Ic disable  . 
+.El
+.It Cm link \&| Cm nolink
+It is convenient to be able to access the current element of a
+file generation set by a fixed name.
+This feature is enabled by
+specifying
+.Cm link
+and disabled using
+.Cm nolink .
+If
+.Cm link
+is specified, a hard link from the current file set
+element to a file without suffix is created.
+When there is already
+a file with this name and the number of links of this file is one,
+it is renamed appending a dot, the letter
+.Ql C ,
+and the pid
+of the
+.Xr ntpd 8   
+server process.
+When the number of links is
+greater than one, the file is unlinked.
+This allows the current
+file to be accessed by a constant name.
+.It Cm enable \&| Cm disable
+Enables or disables the recording function.
+.El
+.El
+.Sh Access Control Support
+.Xr ntpd 8   
+implements a general purpose address-and-mask based
+restriction list.
+The list is sorted by address and by mask, and
+the list is searched in this order for matches, with the last match
+found defining the restriction flags associated with the incoming
+packets.
+The source address of incoming packets is used for the
+match, with the 32- bit address being and'ed with the mask
+associated with the restriction entry and then compared with the
+entry's address (which has also been and'ed with the mask) to look
+for a match.
+Additional information and examples can be found in the
+.Qq "Notes on Configuring NTP and Setting up a NTP Subnet"
+page.
+.Pp
+The restriction facility was implemented in conformance with the
+access policies for the original NSFnet backbone time servers.
+While this facility may be otherwise useful for keeping unwanted or
+broken remote time servers from affecting your own, it should not
+be considered an alternative to the standard NTP authentication
+facility.
+Source address based restrictions are easily circumvented
+by a determined cracker.
+.Ss The Kiss-of-Death Packet
+Ordinarily, packets denied service are simply dropped with no
+further action except incrementing statistics counters.
+Sometimes a
+more proactive response is needed, such as a server message that
+explicitly requests the client to stop sending and leave a message
+for the system operator.
+A special packet format has been created
+for this purpose called the kiss-of-death packet.
+If the
+.Cm kod
+flag is set and either service is denied or the client
+limit is exceeded, the server returns the packet and sets the
+leap bits unsynchronized, stratum zero and the ASCII string "DENY"
+in the reference source identifier field.
+If the
+.Cm kod
+flag
+is not set, the server simply drops the packet.
+.Pp
+A client or peer receiving a kiss-of-death packet performs a set
+of sanity checks to minimize security exposure.
+If this is the
+first packet received from the server, the client assumes an access
+denied condition at the server.
+It updates the stratum and
+reference identifier peer variables and sets the access denied
+(test 4) bit in the peer flash variable.
+If this bit is set, the
+client sends no packets to the server.
+If this is not the first
+packet, the client assumes a client limit condition at the server,
+but does not update the peer variables.
+In either case, a message
+is sent to the system log.
+.Ss Access Control Commands
+.Bl -tag -width indent
+.It Xo Ic restrict numeric_address
+.Op Cm mask Ar numeric_mask
+.Op Ar flag ...
+.Xc
+The
+.Ar numeric_address
+argument, expressed in
+dotted- quad form, is the address of an host or network.
+The
+.Cm mask ,
+also expressed in dotted-quad form,
+defaults to 255.255.255.255, meaning that the
+.Ar numeric_address
+is treated as the address of an
+individual host.
+A default entry (address 0.0.0.0, mask
+0.0.0.0) is always included and, given the sort algorithm,
+is always the first entry in the list.
+Note that, while
+.Ar numeric_address
+is normally given in dotted-quad
+format, the text string
+.Ql default ,
+with no mask option, may
+be used to indicate the default entry.
+In the current implementation,
+.Cm flag
+always
+restricts access, i.e., an entry with no flags indicates that free
+access to the server is to be given.
+The flags are not orthogonal,
+in that more restrictive flags will often make less restrictive
+ones redundant.
+The flags can generally be classed into two
+catagories, those which restrict time service and those which
+restrict informational queries and attempts to do run-time
+reconfiguration of the server.
+One or more of the following flags
+may be specified:
+.Bl -tag -width indent
+.It Cm kod
+If access is denied, send a kiss-of-death packet.
+.It Cm ignore
+Ignore all packets from hosts which match this entry.
+If this
+flag is specified neither queries nor time server polls will be
+responded to.
+.It Cm noquery
+Ignore all NTP mode 6 and 7 packets (i.e. information queries
+and configuration requests) from the source.
+Time service is not
+affected.
+.It Cm nomodify
+Ignore all NTP mode 6 and 7 packets which attempt to modify the
+state of the server (i.e. run time reconfiguration).
+Queries which
+return information are permitted.
+.It Cm notrap
+Decline to provide mode 6 control message trap service to
+matching hosts.
+The trap service is a subsystem of the mode 6
+control message protocol which is intended for use by remote event
+logging programs.
+.It Cm lowpriotrap
+Declare traps set by matching hosts to be low priority.
+The
+number of traps a server can maintain is limited (the current limit
+is 3).
+Traps are usually assigned on a first come, first served
+basis, with later trap requestors being denied service.
+This flag
+modifies the assignment algorithm by allowing low priority traps to
+be overridden by later requests for normal priority traps.
+.It Cm noserve
+Ignore NTP packets whose mode is other than 6 or 7.
+In effect,
+time service is denied, though queries may still be permitted.
+.It Cm nopeer
+Provide stateless time service to polling hosts, but do not
+allocate peer memory resources to these hosts even if they
+otherwise might be considered useful as future synchronization
+partners.
+.It Cm notrust
+Treat these hosts normally in other respects, but never use
+them as synchronization sources.
+.It Cm limited
+These hosts are subject to limitation of number of clients from
+the same net.
+Net in this context refers to the IP notion of net
+(class A, class B, class C, etc.).
+Only the first
+.Va client_limit
+hosts that have shown up at the server and
+that have been active during the last
+.Va client_limit_period
+seconds are accepted.
+Requests from other clients from the same net
+are rejected.
+Only time request packets are taken into account.
+Query packets sent by the
+.Xr ntpq 8   
+and
+.Xr ntpdc 8   
+programs
+are not subject to these limits.
+A history of clients is kept using
+the monitoring capability of
+.Xr ntpd 8  . 
+Thus, monitoring is
+always active as long as there is a restriction entry with the
+.Cm limited
+flag.
+.It Cm ntpport
+This is actually a match algorithm modifier, rather than a
+restriction flag.
+Its presence causes the restriction entry to be
+matched only if the source port in the packet is the standard NTP
+UDP port (123).
+Both
+.Cm ntpport
+and
+.Cm non-ntpport
+may
+be specified.
+The
+.Cm ntpport
+is considered more specific and
+is sorted later in the list.
+.It Cm version   
+Ignore these hosts if not the current NTP version.
+.El
+.Pp
+Default restriction list entries, with the flags
+.Cm ignore ,
+.Cm interface ,
+.Cm ntpport ,
+for each of the local host's interface
+addresses are inserted into the table at startup to prevent the
+server from attempting to synchronize to its own time.
+A default
+entry is also always present, though if it is otherwise
+unconfigured; no flags are associated with the default entry (i.e.,
+everything besides your own NTP server is unrestricted).
+.It Ic clientlimit Ar limit
+Set the
+.Va client_limit
+variable, which limits the number
+of simultaneous access-controlled clients.
+The default value for
+this variable is 3.
+.It Ic clientperiod Ar period
+Set the
+.Va client_limit_period
+variable, which specifies
+the number of seconds after which a client is considered inactive
+and thus no longer is counted for client limit restriction.
+The
+default value for this variable is 3600 seconds.
+.El
+.Sh Reference Clock Support
+The NTP Version 4 daemon supports some three dozen different radio,
+satellite and modem reference clocks plus a special pseudo-clock
+used for backup or when no other clock source is available.
+Detailed descriptions of individual device drivers and options can
+be found in the
+.Qq "Reference Clock Drivers"
+page
+(available as part of the HTML documentation
+provided in
+.Pa /usr/share/doc/ntp ) .
+Additional information can be found in the pages linked
+there, including the
+.Qq "Debugging Hints for Reference Clock Drivers"
+and
+.Qq "How To Write a Reference Clock Driver"
+pages.
+In addition, support for a PPS
+signal is available as described in the
+.Qq "Pulse-per-second (PPS) Signal Interfacing"
+page.
+Many
+drivers support special line discipline/streams modules which can
+significantly improve the accuracy using the driver.
+These are
+described in the
+.Qq "Line Disciplines and Streams Drivers"
+page.
+.Pp
+A reference clock will generally (though not always) be a radio
+timecode receiver which is synchronized to a source of standard
+time such as the services offered by the NRC in Canada and NIST and
+USNO in the US.
+The interface between the computer and the timecode
+receiver is device dependent, but is usually a serial port.
+A
+device driver specific to each reference clock must be selected and
+compiled in the distribution; however, most common radio, satellite
+and modem clocks are included by default.
+Note that an attempt to
+configure a reference clock when the driver has not been compiled
+or the hardware port has not been appropriately configured results
+in a scalding remark to the system log file, but is otherwise non
+hazardous.
+.Pp
+For the purposes of configuration,
+.Xr ntpd 8
+treats
+reference clocks in a manner analogous to normal NTP peers as much
+as possible.
+Reference clocks are identified by a syntactically
+correct but invalid IP address, in order to distinguish them from
+normal NTP peers.
+Reference clock addresses are of the form
+.Sm off
+.Li 127.127. Ar t . Ar u ,
+.Sm on
+where
+.Ar t
+is an integer
+denoting the clock type and
+.Ar u
+indicates the unit
+number in the range 0-3.
+While it may seem overkill, it is in fact
+sometimes useful to configure multiple reference clocks of the same
+type, in which case the unit numbers must be unique.
+.Pp
+The
+.Ic server
+command is used to configure a reference
+clock, where the
+.Ar address
+argument in that command
+is the clock address.
+The
+.Cm key  ,
+.Cm version
+and
+.Cm ttl
+options are not used for reference clock support.
+The
+.Cm mode
+option is added for reference clock support, as
+described below.
+The
+.Cm prefer
+option can be useful to
+persuade the server to cherish a reference clock with somewhat more
+enthusiasm than other reference clocks or peers.
+Further
+information on this option can be found in the
+.Qq "Mitigation Rules and the prefer Keyword"
+page.
+The
+.Cm minpoll
+and
+.Cm maxpoll
+options have
+meaning only for selected clock drivers.
+See the individual clock
+driver document pages for additional information.
+.Pp
+The
+.Ic fudge
+command is used to provide additional
+information for individual clock drivers and normally follows
+immediately after the
+.Ic server
+command.
+The
+.Ar address
+argument specifies the clock address.
+The
+.Cm refid
+and
+.Cm stratum
+options can be used to
+override the defaults for the device.
+There are two optional
+device-dependent time offsets and four flags that can be included
+in the
+.Ic fudge   
+command as well.
+.Pp
+The stratum number of a reference clock is by default zero.
+Since the
+.Xr ntpd 8
+daemon adds one to the stratum of each
+peer, a primary server ordinarily displays an external stratum of
+one.
+In order to provide engineered backups, it is often useful to
+specify the reference clock stratum as greater than zero.
+The
+.Cm stratum   
+option is used for this purpose.
+Also, in cases
+involving both a reference clock and a pulse-per-second (PPS)
+discipline signal, it is useful to specify the reference clock
+identifier as other than the default, depending on the driver.
+The
+.Cm refid
+option is used for this purpose.
+Except where noted,
+these options apply to all clock drivers.

+precision PPS signal.
+It also provides a way to correct a

+latencies, different cable lengths or receiver internal delay.
+The
+specified offset is in addition to the propagation delay provided
+by other means, such as internal DIPswitches.

+.It Ic broadcastdelay Ar seconds
+The broadcast and multicast modes require a special calibration
+to determine the network delay between the local and remote
+servers.
+Ordinarily, this is done automatically by the initial
+protocol exchanges between the client and server.
+In some cases,
+the calibration procedure may fail due to network or server access
+controls, for example.
+This command specifies the default delay to
+be used under these circumstances.
+Typically (for Ethernet), a
+number between 0.003 and 0.007 seconds is appropriate.
+The default
+when this command is not used is 0.004 seconds.
+.It Ic driftfile Ar driftfile
+This command specifies the name of the file used to record the
+frequency offset of the local clock oscillator.
+If the file exists,
+it is read at startup in order to set the initial frequency offset
+and then updated once per hour with the current frequency offset
+computed by the daemon.
+If the file does not exist or this command
+is not given, the initial frequency offset is assumed zero.
+In this
+case, it may take some hours for the frequency to stabilize and the
+residual timing errors to subside.
+.Pp
+The file format consists of a single line containing a single
+floating point number, which records the frequency offset measured
+in parts-per-million (PPM).
+The file is updated by first writing
+the current drift value into a temporary file and then renaming
+this file to replace the old version.
+This implies that
+.Xr ntpd 8
+must have write permission for the directory the
+drift file is located in, and that filesystem links, symbolic or
+otherwise, should be avoided.

+This command configures a trap receiver at the given host

+.Pp
+The trap receiver will generally log event messages and other

+.Sh DESCRIPTION
+Following is a description of the format of NTP key files.
+For a description of the use of these files, see the
+.Qq Authentication Support
+section of the
+.Xr ntp.conf 5
+page.
+.Pp
+In the case of DES, the keys are 56 bits long with,
+depending on type, a parity check on each byte.
+In the case of MD5, the keys are 64 bits (8 bytes).
+.Xr ntpd 8
+reads its keys from a file specified using the
+.Fl k
+command line option or the
+.Ic keys
+statement in the configuration file.
+While key number 0 is fixed by the NTP standard
+(as 56 zero bits)
+and may not be changed,
+one or more of the keys numbered 1 through 15
+may be arbitrarily set in the keys file.
+.Pp
+The key file uses the same comment conventions
+as the configuration file.
+Key entries use a fixed format of the form
+.Pp
+.D1 Ar keyno type key
+.Pp
+where
+.Ar keyno
+is a positive integer,
+.Ar type
+is a single character which defines the key format,
+and
+.Ar key
+is the key itself.
+.Pp
+The
+.Ar key
+may be given in one of four different formats,
+controlled by the
+.Ar type
+character.
+The four key types, and corresponding formats,
+are listed following.
+.Bl -tag -width X
+.It Li S
+The key is a 64-bit hexadecimal number in the format
+specified in the DES specification;
+that is, the high order seven bits of each octet are used
+to form the 56-bit key
+while the low order bit of each octet is given a value
+such that odd parity is maintained for the octet.
+Leading zeroes must be specified
+(i.e., the key must be exactly 16 hex digits long)
+and odd parity must be maintained.
+Hence a zero key, in standard format, would be given as
+.Ql 0101010101010101 .
+.It Li N
+The key is a 64-bit hexadecimal number in the format
+specified in the NTP standard.
+This is the same as the DES format,
+except the bits in each octet have been rotated one bit right
+so that the parity bit is now the high order bit of the octet.
+Leading zeroes must be specified and odd parity must be maintained.
+A zero key in NTP format would be specified as
+.Ql 8080808080808080 .
+.It Li A
+The key is a 1-to-8 character ASCII string.
+A key is formed from this by using the low order 7 bits
+of each ASCII character in the string,
+with zeroes added on the right
+when necessary to form a full width 56-bit key,
+in the same way that encryption keys are formed from
+.Ux
+passwords.
+.It Li M
+The key is a 1-to-8 character ASCII string,
+using the MD5 authentication scheme.
+Note that both the keys and the authentication schemes (DES or MD5)
+must be identical between a set of peers sharing the same key number.
+.El
+.Pp
+Note that the keys used by the
+.Xr ntpq 8
+and
+.Xr ntpdc 8
+programs are checked against passwords
+requested by the programs and entered by hand,

+.Sh DESCRIPTION
+The
+.Nm
+program is an operating system daemon which sets
+and maintains the system time of day in synchronism with Internet
+standard time servers.
+It is a complete implementation of the
+Network Time Protocol (NTP) version 4, but also retains
+compatibility with version 3, as defined by RFC-1305, and version 1
+and 2, as defined by RFC-1059 and RFC-1119, respectively.
+.Pp
+.Nm
+does most computations in 64-bit floating point
+arithmetic and does relatively clumsy 64-bit fixed point operations
+only when necessary to preserve the ultimate precision, about 232
+picoseconds.
+While the ultimate precision, is not achievable with
+ordinary workstations and networks of today, it may be required
+with future gigahertz CPU clocks and gigabit LANs.
+.Pp
+Ordinarily,
+.Nm
+reads the
+.Xr ntp.conf 5
+configuration file at startup time in order to determine the
+synchronization sources and operating modes.
+It is also possible to
+specify a working, although limited, configuration entirely on the
+command line, obviating the need for a configuration file.
+This may
+be particularly useful when the local host is to be configured as a
+broadcast/multicast client, with all peers being determined by
+listening to broadcasts at run time.
+.Pp
+If NetInfo support is built into
+.Nm ,
+then
+.Nm
+will attempt to read its configuration from the
+NetInfo if the default
+.Xr ntp.conf 5
+file cannot be read and no file is
+specified by the
+.Fl c
+option.
+.Pp
+Various internal
+.Nm
+variables can be displayed and
+configuration options altered while the
+.Nm
+is running
+using the
+.Xr ntpq 8
+and
+.Xr ntpdc 8
+utility programs.
+.Pp
+When
+.Nm
+starts it looks at the value of
+.Xr umask 2 ,
+and if zero
+.Nm
+will set the
+.Xr umask 2
+to 022.

+Specify the name and path of the drift file.
+.It Fl g
+Normally,
+.Nm
+exits if the offset exceeds the sanity
+limit, which is 1000 s by default.
+If the sanity limit is set to
+zero, no sanity checking is performed and any offset is acceptable.
+This option overrides the limit and allows the time to be set to
+any value without restriction; however, this can happen only once.
+After that,
+.Nm
+will exit if the limit is exceeded.
+This
+option can be used with the
+.Fl q
+option.
+.It Fl k Ar keyfile
+Specify the name and path of the file containing the NTP
+authentication keys.
+.It Fl l Ar logfile
+Specify the name and path of the log file.
+The default is the

+Exit the

+This behavior mimics that of the

+which is to be retired.
+The

+options can
+be used with this option.
+.It Fl r Ar broadcastdelay
+Specify the default propagation delay from the
+broadcast/multicast server and this computer.
+This is necessary
+only if the delay cannot be computed automatically by the
+protocol.
+.It Fl s Ar statsdir
+Specify the directory path for files created by the statistics
+facility.
+.It Fl t Ar key
+Add a key number to the trusted key list.
+.It Fl v Ar variable
+.It Fl V Ar variable
+Add a system variable listed by default.
+.It Fl x
+Normally, the time is slewed if the offset is less than the
+step threshold, which is 128 ms by default, and stepped if above
+the threshold.
+This option forces the time to be slewed in all
+cases.
+If the step threshold is set to zero, all offsets are
+stepped, regardless of value and regardless of the
+.Fl x
+option.
+In general, this is not a good idea, as it bypasses the
+clock state machine which is designed to cope with large time and
+frequency errors Note: Since the slew rate is limited to 0.5 ms/s,
+each second of adjustment requires an amortization interval of 2000
+s.
+Thus, an adjustment of many seconds can take hours or days to
+amortize.
+This option can be used with the
+.Fl q
+option.
+.El
+.Ss "How NTP Operates"
+The
+.Nm
+program operates by exchanging messages with
+one or more configured servers at designated poll intervals.
+When
+started, whether for the first or subsequent times, the program
+requires several exchanges from the majority of these servers so
+the signal processing and mitigation algorithms can accumulate and
+groom the data and set the clock.
+In order to protect the network
+from bursts, the initial poll interval for each server is delayed
+an interval randomized over 0-16s.
+At the default initial poll
+interval of 64s, several minutes can elapse before the clock is
+set.
+The initial delay to set the clock can be reduced using the
+.Cm iburst
+keyword with the
+.Ic server
+configuration
+command, as described in
+.Xr ntp.conf 5 .
+.Pp
+Most operating systems and hardware of today incorporate a
+time-of-year (TOY) chip to maintain the time during periods when
+the power is off.
+When the machine is booted, the chip is used to
+initialize the operating system time.
+After the machine has
+synchronized to a NTP server, the operating system corrects the
+chip from time to time.
+In case there is no TOY chip or for some
+reason its time is more than 1000s from the server time,
+.Nm
+assumes something must be terribly wrong and the only
+reliable action is for the operator to intervene and set the clock
+by hand.
+This causes
+.Nm
+to exit with a panic message to
+the system log.
+The
+.Fl g
+option overrides this check and the
+clock will be set to the server time regardless of the chip time.
+However, and to protect against broken hardware, such as when the
+CMOS battery fails or the clock counter becomes defective, once the
+clock has been set, an error greater than 1000s will cause
+.Nm
+to exit anyway.
+.Pp
+Under ordinary conditions,
+.Nm
+adjusts the clock in
+small steps so that the timescale is effectively continuous and
+without discontinuities.
+Under conditions of extreme network
+congestion, the roundtrip delay jitter can exceed three seconds and
+the synchronization distance, which is equal to one-half the
+roundtrip delay plus error budget terms, can become very large.
+The
+.Nm
+algorithms discard sample offsets exceeding 128 ms,
+unless the interval during which no sample offset is less than 128
+ms exceeds 900s.
+The first sample after that, no matter what the
+offset, steps the clock to the indicated time.
+In practice this
+reduces the false alarm rate where the clock is stepped in error to
+a vanishingly low incidence.
+.Pp
+As the result of this behavior, once the clock has been set, it
+very rarely strays more than 128 ms, even under extreme cases of
+network path congestion and jitter.
+Sometimes, in particular when
+.Nm
+is first started, the error might exceed 128 ms.
+This
+may on occasion cause the clock to be set backwards if the local
+clock time is more than 128 s in the future relative to the server.
+In some applications, this behavior may be unacceptable.
+If the
+.Fl x
+option is included on the command line, the clock will
+never be stepped and only slew corrections will be used.
+.Pp
+The issues should be carefully explored before deciding to use
+the
+.Fl x
+option.
+The maximum slew rate possible is limited
+to 500 parts-per-million (PPM) as a consequence of the correctness
+principles on which the NTP protocol and algorithm design are
+based.
+As a result, the local clock can take a long time to
+converge to an acceptable offset, about 2,000 s for each second the
+clock is outside the acceptable range.
+During this interval the
+local clock will not be consistent with any other network clock and
+the system cannot be used for distributed applications that require
+correctly synchronized network time.
+.Pp
+In spite of the above precautions, sometimes when large
+frequency errors are present the resulting time offsets stray
+outside the 128-ms range and an eventual step or slew time
+correction is required.
+If following such a correction the
+frequency error is so large that the first sample is outside the
+acceptable range,
+.Nm
+enters the same state as when the
+.Pa ntp.drift
+file is not present.
+The intent of this behavior
+is to quickly correct the frequency and restore operation to the
+normal tracking mode.
+In the most extreme cases
+(time.ien.it comes to mind), there may be occasional
+step/slew corrections and subsequent frequency corrections.
+It
+helps in these cases to use the
+.Cm burst
+keyword when
+configuring the server.
+.Ss "Frequency Discipline"
+The
+.Nm
+behavior at startup depends on whether the
+frequency file, usually
+.Pa ntp.drift ,
+exists.
+This file
+contains the latest estimate of clock frequency error.
+When the
+.Nm
+is started and the file does not exist, the
+.Nm
+enters a special mode designed to quickly adapt to
+the particular system clock oscillator time and frequency error.
+This takes approximately 15 minutes, after which the time and
+frequency are set to nominal values and the
+.Nm
+enters
+normal mode, where the time and frequency are continuously tracked
+relative to the server.
+After one hour the frequency file is
+created and the current frequency offset written to it.
+When the
+.Nm
+is started and the file does exist, the
+.Nm
+frequency is initialized from the file and enters normal mode
+immediately.
+After that the current frequency offset is written to
+the file at hourly intervals.
+.Ss "Operating Modes"
+.Nm
+can operate in any of several modes, including
+symmetric active/passive, client/server broadcast/multicast and
+manycast, as described in the
+.Qq Association Management
+page
+(available as part of the HTML documentation
+provided in
+.Pa /usr/share/doc/ntp ) .
+It normally operates continuously while
+monitoring for small changes in frequency and trimming the clock
+for the ultimate precision.
+However, it can operate in a one-time
+mode where the time is set from an external server and frequency is
+set from a previously recorded frequency file.
+A
+broadcast/multicast or manycast client can discover remote servers,
+compute server-client propagation delay correction factors and
+configure itself automatically.
+This makes it possible to deploy a
+fleet of workstations without specifying configuration details
+specific to the local environment.
+.Pp
+By default,
+.Nm
+runs in continuous mode where each of
+possibly several external servers is polled at intervals determined
+by an intricate state machine.
+The state machine measures the
+incidental roundtrip delay jitter and oscillator frequency wander
+and determines the best poll interval using a heuristic algorithm.
+Ordinarily, and in most operating environments, the state machine
+will start with 64s intervals and eventually increase in steps to
+1024s.
+A small amount of random variation is introduced in order to
+avoid bunching at the servers.
+In addition, should a server become
+unreachable for some time, the poll interval is increased in steps
+to 1024s in order to reduce network overhead.
+.Pp
+In some cases it may not be practical for
+.Nm
+to run
+continuously.
+A common workaround has been to run the
+.Xr ntpdate 8
+program from a
+.Xr cron 8
+job at designated
+times.
+However, this program does not have the crafted signal
+processing, error checking and mitigation algorithms of
+.Nm .
+The
+.Fl q
+option is intended for this purpose.
+Setting this option will cause
+.Nm
+to exit just after
+setting the clock for the first time.
+The procedure for initially
+setting the clock is the same as in continuous mode; most
+applications will probably want to specify the
+.Cm iburst
+keyword with the
+.Ic server
+configuration command.
+With this
+keyword a volley of messages are exchanged to groom the data and
+the clock is set in about a minute.
+If nothing is heard after a
+couple of minutes, the daemon times out and exits.
+After a suitable
+period of mourning, the
+.Xr ntpdate 8
+program may be
+retired.
+.Pp
+When kernel support is available to discipline the clock
+frequency, which is the case for stock Solaris, Tru64, Linux and
+.Fx ,
+a useful feature is available to discipline the clock
+frequency.
+First,
+.Nm
+is run in continuous mode with
+selected servers in order to measure and record the intrinsic clock
+frequency offset in the frequency file.
+It may take some hours for
+the frequency and offset to settle down.
+Then the
+.Nm
+is
+stopped and run in one-time mode as required.
+At each startup, the
+frequency is read from the file and initializes the kernel
+frequency.
+.Ss "Poll Interval Control"
+This version of NTP includes an intricate state machine to
+reduce the network load while maintaining a quality of
+synchronization consistent with the observed jitter and wander.
+There are a number of ways to tailor the operation in order enhance
+accuracy by reducing the interval or to reduce network overhead by
+increasing it.
+However, the user is advised to carefully consider
+the consequences of changing the poll adjustment range from the
+default minimum of 64 s to the default maximum of 1,024 s.
+The
+default minimum can be changed with the
+.Ic tinker
+.Cm minpoll
+command to a value not less than 16 s.
+This value is used for all
+configured associations, unless overridden by the
+.Cm minpoll
+option on the configuration command.
+Note that most device drivers
+will not operate properly if the poll interval is less than 64 s
+and that the broadcast server and manycast client associations will
+also use the default, unless overridden.
+.Pp
+In some cases involving dial up or toll services, it may be
+useful to increase the minimum interval to a few tens of minutes
+and maximum interval to a day or so.
+Under normal operation
+conditions, once the clock discipline loop has stabilized the
+interval will be increased in steps from the minimum to the
+maximum.
+However, this assumes the intrinsic clock frequency error
+is small enough for the discipline loop correct it.
+The capture
+range of the loop is 500 PPM at an interval of 64s decreasing by a
+factor of two for each doubling of interval.
+At a minimum of 1,024
+s, for example, the capture range is only 31 PPM.
+If the intrinsic
+error is greater than this, the drift file
+.Pa ntp.drift
+will
+have to be specially tailored to reduce the residual error below
+this limit.
+Once this is done, the drift file is automatically
+updated once per hour and is available to initialize the frequency
+on subsequent daemon restarts.
+.Ss "The huff-n'-puff filter"
+In scenarios where a considerable amount of data are to be
+downloaded or uploaded over telephone modems, timekeeping quality
+can be seriously degraded.
+This occurs because the differential
+delays on the two directions of transmission can be quite large.
+In
+many cases the apparent time errors are so large as to exceed the
+step threshold and a step correction can occur during and after the
+data transfer is in progress.
+.Pp
+The huff-n'-puff filter is designed to correct the apparent time
+offset in these cases.
+It depends on knowledge of the propagation
+delay when no other traffic is present.
+In common scenarios this
+occurs during other than work hours.
+The filter maintains a shift
+register that remembers the minimum delay over the most recent
+interval measured usually in hours.
+Under conditions of severe
+delay, the filter corrects the apparent offset using the sign of
+the offset and the difference between the apparent delay and
+minimum delay.
+The name of the filter reflects the negative (huff)
+and positive (puff) correction, which depends on the sign of the
+offset.
+.Pp
+The filter is activated by the
+.Ic tinker command and
+.Cm huffpuff
+keyword, as described in
+.Xr ntp.conf 5 .

+.Pp
+.Em Note :
+The functionality of this program is now available
+in the
+.Xr ntpd 8
+program.
+See the
+.Fl q
+command line
+option in the
+.Xr ntpd 8
+page.
+After a suitable period of
+mourning, the
+.Nm
+program is to be retired from this
+distribution.
+.Pp
+.Nm
+sets the local date and time by polling the
+Network Time Protocol (NTP) server(s) given as the
+.Ar server
+arguments to determine the correct time.
+It must be run as root on
+the local host.
+A number of samples are obtained from each of the
+servers specified and a subset of the NTP clock filter and
+selection algorithms are applied to select the best of these.
+Note
+that the accuracy and reliability of
+.Nm
+depends on
+the number of servers, the number of polls each time it is run and
+the interval between runs.
+.Pp
+The following options are available:
+.Bl -tag -width indent
+.It Fl a Ar key
+Enable the authentication function and specify the key
+identifier to be used for authentication as the argument
+.Ar key .
+The keys and key identifiers must match
+in both the client and server key files.
+The default is to disable
+the authentication function.
+.It Fl B
+Force the time to always be slewed using the
+.Xr adjtime 2
+system
+call, even if the measured offset is greater than +-128 ms.
+The
+default is to step the time using
+.Xr settimeofday 2
+if the offset is
+greater than +-128 ms.
+Note that, if the offset is much greater
+than +-128 ms in this case, it can take a long time (hours) to
+slew the clock to the correct value.
+During this time, the host
+should not be used to synchronize clients.
+.It Fl b
+Force the time to be stepped using the
+.Xr settimeofday 2
+system
+call, rather than slewed (default) using the
+.Xr adjtime 2
+system call.
+This option should be used when called from a startup file at boot
+time.
+.It Fl d
+Enable the debugging mode, in which
+.Nm
+will go
+through all the steps, but not adjust the local clock.
+Information
+useful for general debugging will also be printed.
+.It Fl e Ar authdelay
+Specify the processing delay to perform an authentication
+function as the value
+.Ar authdelay ,
+in seconds and fraction
+(see
+.Xr ntpd 8
+for details).
+This number is usually small
+enough to be negligible for most purposes, though specifying a
+value may improve timekeeping on very slow CPU's.
+.It Fl k Ar keyfile
+Specify the path for the authentication key file as the string
+.Ar keyfile .
+The default is
+.Pa /etc/ntp.keys .
+This file
+should be in the format described in
+.Xr ntpd 8 .
+.It Fl o Ar version
+Specify the NTP version for outgoint packets as the integer
+.Ar version ,
+which can be 1 or 2.
+The default is 3.
+This allows
+.Nm
+to be used with older NTP versions.
+.It Fl p Ar samples
+Specify the number of samples to be acquired from each server
+as the integer
+.Ar samples ,
+with values from 1 to 8 inclusive.
+The default is 4.
+.It Fl q
+Query only - don't set the clock.
+.It Fl s
+Divert logging output from the standard output (default) to the
+system
+.Xr syslog 3
+facility.
+This is designed primarily for
+convenience of
+.Xr cron 8
+scripts.
+.It Fl t Ar timeout
+Specify the maximum time waiting for a server response as the
+value
+.Ar timeout ,
+in seconds and fraction.
+The value is
+rounded to a multiple of 0.2 seconds.
+The default is 1 second, a
+value suitable for polling across a LAN.
+.It Fl u
+Direct
+.Nm
+to use an unprivileged port for outgoing
+packets.
+This is most useful when behind a firewall that blocks
+incoming traffic to privileged ports, and you want to synchronise
+with hosts beyond the firewall.
+Note that the
+.Fl d
+option
+always uses unprivileged ports.
+.It Fl v
+Be verbose.
+This option will cause
+.Nm Ns 's
+version
+identification string to be logged.
+.El
+.Pp
+.Nm
+can be run manually as necessary to set the
+host clock, or it can be run from the host startup script to set
+the clock at boot time.
+This is useful in some cases to set the
+clock initially before starting the NTP daemon
+.Xr ntpd 8 .
+It is
+also possible to run
+.Nm
+from a
+.Xr cron 8
+script.
+However, it is important to note that
+.Nm
+with
+contrived
+.Xr cron 8
+scripts is no substitute for the NTP
+daemon, which uses sophisticated algorithms to maximize accuracy
+and reliability while minimizing resource use.
+Finally, since
+.Nm
+does not discipline the host clock frequency as
+does
+.Xr ntpd 8 ,
+the accuracy using
+.Nm
+is
+limited.
+.Pp
+Time adjustments are made by
+.Nm
+in one of two
+ways.
+If
+.Nm
+determines the clock is in error more
+than 0.5 second it will simply step the time by calling the system
+.Xr settimeofday 2
+routine.
+If the error is less than 0.5
+seconds, it will slew the time by calling the system
+.Xr adjtime 2
+routine.
+The latter technique is less disruptive
+and more accurate when the error is small, and works quite well
+when
+.Nm
+is run by
+.Xr cron 8
+every hour or
+two.
+.Pp
+.Nm
+will decline to set the date if an NTP server
+daemon (e.g.,
+.Xr ntpd 8 )
+is running on the same host.
+When
+running
+.Nm
+on a regular basis from
+.Xr cron 8
+as
+an alternative to running a daemon, doing so once every hour or two
+will result in precise enough timekeeping to avoid stepping the
+clock.
+.Pp
+If NetInfo support is compiled into
+.Nm , 
+then the
+.Ic server
+argument is optional if
+.Nm
+can find a
+time server in the NetInfo configuration for
+.Xr ntpd 8 .

+.Sh NAME
+.Nm ntpdc
+.Nd special NTP query program
+.Sh SYNOPSIS
+.Nm
+.Op Fl ilnps
+.Op Fl c Ar command
+.Op Ar host ...
+.Sh DESCRIPTION
+.Nm
+is used to query the
+.Xr ntpd 8
+daemon about its
+current state and to request changes in that state.
+The program may
+be run either in interactive mode or controlled using command line
+arguments.
+Extensive state and statistics information is available
+through the
+.Nm
+interface.
+In addition, nearly all the
+configuration options which can be specified at startup using
+ntpd's configuration file may also be specified at run time using
+.Nm .
+.Pp
+The following options are available:
+.Bl -tag -width indent
+.It Fl c Ar command
+The following argument is interpreted as an interactive format
+command and is added to the list of commands to be executed on the
+specified host(s).
+Multiple
+.Fl c
+options may be given.
+.It Fl i
+Force
+.Nm
+to operate in interactive mode.
+Prompts
+will be written to the standard output and commands read from the
+standard input.
+.It Fl l
+Obtain a list of peers which are known to the server(s).
+This
+switch is equivalent to
+.Ql -c listpeers .
+.It Fl n
+Output all host addresses in dotted-quad numeric format rather
+than converting to the canonical host names.
+.It Fl p
+Print a list of the peers known to the server as well as a
+summary of their state.
+This is equivalent to
+.Ql -c peers .
+.It Fl s
+Print a list of the peers known to the server as well as a
+summary of their state, but in a slightly different format than the
+.Fl p
+switch.
+This is equivalent to
+.Ql -c dmpeers .
+.El
+.Pp
+If one or more request options are included on the command line
+when
+.Nm
+is executed, each of the requests will be sent
+to the NTP servers running on each of the hosts given as command
+line arguments, or on localhost by default.
+If no request options
+are given,
+.Nm
+will attempt to read commands from the
+standard input and execute these on the NTP server running on the
+first host given on the command line, again defaulting to localhost
+when no other host is specified.
+.Nm
+will prompt for
+commands if the standard input is a terminal device.
+.Pp
+.Nm
+uses NTP mode 7 packets to communicate with the
+NTP server, and hence can be used to query any compatable server on
+the network which permits it.
+Note that since NTP is a UDP protocol
+this communication will be somewhat unreliable, especially over
+large distances in terms of network topology.
+.Nm
+makes
+no attempt to retransmit requests, and will time requests out if
+the remote host is not heard from within a suitable timeout
+time.
+.Pp
+The operation of
+.Nm
+are specific to the particular
+implementation of the
+.Xr ntpd 8
+daemon and can be expected to
+work only with this and maybe some previous versions of the daemon.
+Requests from a remote
+.Nm
+program which affect the
+state of the local server must be authenticated, which requires
+both the remote program and local server share a common key and key
+identifier.
+Specifying a command line option other than
+.Fl i
+or
+.Fl n
+will cause the specified query (queries) to be sent to
+the indicated host(s) immediately.
+Otherwise,
+.Nm
+will
+attempt to read interactive format commands from the standard
+input.
+.Ss "Interactive Commands"
+Interactive format commands consist of a keyword followed by zero
+to four arguments.
+Only enough characters of the full keyword to
+uniquely identify the command need be typed.
+The output of a
+command is normally sent to the standard output, but optionally the
+output of individual commands may be sent to a file by appending a
+.Ql \&> ,
+followed by a file name, to the command line.
+.Pp
+A number of interactive format commands are executed entirely
+within the
+.Nm
+program itself and do not result in NTP
+mode 7 requests being sent to a server.
+These are described
+following.
+.Bl -tag -width indent
+.It Ic \&? Ar command_keyword
+.It Ic help Ar command_keyword
+A
+.Ic \&?
+will print a list of all the command
+keywords known to this incarnation of
+.Nm .
+A
+.Ic \&?
+followed by a command keyword will print function and usage
+information about the command.
+This command is probably a better
+source of information about
+.Xr ntpq 8
+than this manual
+page.
+.It Ic delay Ar milliseconds
+Specify a time interval to be added to timestamps included in
+requests which require authentication.
+This is used to enable
+(unreliable) server reconfiguration over long delay network paths
+or between machines whose clocks are unsynchronized.
+Actually the
+server does not now require timestamps in authenticated requests,
+so this command may be obsolete.
+.It Ic host Ar hostname
+Set the host to which future queries will be sent.
+Hostname may
+be either a host name or a numeric address.
+.It Ic hostnames Op Cm yes | Cm no
+If
+.Cm yes
+is specified, host names are printed in
+information displays.
+If
+.Cm no
+is specified, numeric
+addresses are printed instead.
+The default is
+.Cm yes ,
+unless
+modified using the command line
+.Fl n
+switch.
+.It Ic keyid Ar keyid
+This command allows the specification of a key number to be
+used to authenticate configuration requests.
+This must correspond
+to a key number the server has been configured to use for this
+purpose.
+.It Ic quit
+Exit
+.Nm .
+.It Ic passwd
+This command prompts you to type in a password (which will not
+be echoed) which will be used to authenticate configuration
+requests.
+The password must correspond to the key configured for
+use by the NTP server for this purpose if such requests are to be
+successful.
+.It Ic timeout Ar milliseconds
+Specify a timeout period for responses to server queries.
+The
+default is about 8000 milliseconds.
+Note that since
+.Nm
+retries each query once after a timeout, the total waiting time for
+a timeout will be twice the timeout value set.
+.El
+.Ss "Control Message Commands"
+Query commands result in NTP mode 7 packets containing requests for
+information being sent to the server.
+These are read-only commands
+in that they make no modification of the server configuration
+state.
+.Bl -tag -width indent
+.It Ic listpeers
+Obtains and prints a brief list of the peers for which the
+server is maintaining state.
+These should include all configured
+peer associations as well as those peers whose stratum is such that
+they are considered by the server to be possible future
+synchonization candidates.
+.It Ic peers
+Obtains a list of peers for which the server is maintaining
+state, along with a summary of that state.
+Summary information
+includes the address of the remote peer, the local interface
+address (0.0.0.0 if a local address has yet to be determined), the
+stratum of the remote peer (a stratum of 16 indicates the remote
+peer is unsynchronized), the polling interval, in seconds, the
+reachability register, in octal, and the current estimated delay,
+offset and dispersion of the peer, all in seconds.
+.Pp
+The character in the left margin indicates the mode this peer
+entry is operating in.
+A
+.Ql \&+
+denotes symmetric active, a
+.Ql \&-
+indicates symmetric passive, a
+.Ql \&=
+means the
+remote server is being polled in client mode, a
+.Ql \&^
+indicates that the server is broadcasting to this address, a
+.Ql \&~
+denotes that the remote peer is sending broadcasts and a
+.Ql \&*
+marks the peer the server is currently synchonizing
+to.
+.Pp
+The contents of the host field may be one of four forms.
+It may
+be a host name, an IP address, a reference clock implementation
+name with its parameter or
+.Fn REFCLK "implementation_number" "parameter" .
+On
+.Ic hostnames
+.Cm no
+only IP-addresses
+will be displayed.
+.It Ic dmpeers
+A slightly different peer summary list.
+Identical to the output
+of the
+.Ic peers
+command, except for the character in the
+leftmost column.
+Characters only appear beside peers which were
+included in the final stage of the clock selection algorithm.
+A
+.Ql \&.   
+indicates that this peer was cast off in the falseticker
+detection, while a
+.Ql \&+   
+indicates that the peer made it
+through.
+A
+.Ql \&*   
+denotes the peer the server is currently
+synchronizing with.
+.It Ic showpeer Ar peer_address ...
+Shows a detailed display of the current peer variables for one
+or more peers.
+Most of these values are described in the NTP
+Version 2 specification.
+.It Ic pstats Ar peer_address ...
+Show per-peer statistic counters associated with the specified
+peer(s).
+.It Ic clockinfo Ar clock_peer_address ...
+Obtain and print information concerning a peer clock.
+The
+values obtained provide information on the setting of fudge factors
+and other clock performance information.
+.It Ic kerninfo
+Obtain and print kernel phase-lock loop operating parameters.
+This information is available only if the kernel has been specially
+modified for a precision timekeeping function.
+.It Ic loopinfo Op Cm oneline | Cm multiline
+Print the values of selected loop filter variables.
+The loop
+filter is the part of NTP which deals with adjusting the local
+system clock.
+The
+.Sq offset
+is the last offset given to the
+loop filter by the packet processing code.
+The
+.Sq frequency
+is the frequency error of the local clock in parts-per-million
+(ppm).
+The
+.Sq time_const
+controls the stiffness of the
+phase-lock loop and thus the speed at which it can adapt to
+oscillator drift.
+The
+.Sq watchdog timer
+value is the number
+of seconds which have elapsed since the last sample offset was
+given to the loop filter.
+The
+.Cm oneline
+and
+.Cm multiline
+options specify the format in which this
+information is to be printed, with
+.Cm multiline
+as the
+default.
+.It Ic sysinfo
+Print a variety of system state variables, i.e., state related
+to the local server.
+All except the last four lines are described
+in the NTP Version 3 specification, RFC-1305.
+.Pp
+The
+.Sq system flags
+show various system flags, some of
+which can be set and cleared by the
+.Ic enable
+and
+.Ic disable
+configuration commands, respectively.
+These are
+the
+.Cm auth  ,
+.Cm bclient ,
+.Cm monitor ,
+.Cm pll ,
+.Cm pps
+and
+.Cm stats
+flags.
+See the
+.Xr ntpd 8
+documentation for the meaning of these flags.
+There
+are two additional flags which are read only, the
+.Cm kernel_pll
+and
+.Cm kernel_pps .
+These flags indicate
+the synchronization status when the precision time kernel
+modifications are in use.
+The
+.Sq kernel_pll
+indicates that
+the local clock is being disciplined by the kernel, while the
+.Sq kernel_pps
+indicates the kernel discipline is provided by the PPS
+signal.
+.Pp
+The
+.Sq stability
+is the residual frequency error remaining
+after the system frequency correction is applied and is intended for
+maintenance and debugging.
+In most architectures, this value will
+initially decrease from as high as 500 ppm to a nominal value in
+the range .01 to 0.1 ppm.
+If it remains high for some time after
+starting the daemon, something may be wrong with the local clock,
+or the value of the kernel variable
+.Va kern.clockrate.tick
+may be
+incorrect.
+.Pp
+The
+.Sq broadcastdelay
+shows the default broadcast delay,
+as set by the
+.Ic broadcastdelay
+configuration command.
+.Pp

+.Ss "Runtime Configuration Requests"
+All requests which cause state changes in the server are
+authenticated by the server using a configured NTP key (the
+facility can also be disabled by the server by not configuring a
+key).
+The key number and the corresponding key must also be made
+known to
+.Nm .
+This can be done using the
+.Ic keyid
+and
+.Ic passwd
+commands, the latter of which will prompt at the terminal for a
+password to use as the encryption key.
+You will also be prompted
+automatically for both the key number and password the first time a
+command which would result in an authenticated request to the
+server is given.
+Authentication not only provides verification that
+the requester has permission to make such changes, but also gives
+an extra degree of protection again transmission errors.
+.Pp
+Authenticated requests always include a timestamp in the packet
+data, which is included in the computation of the authentication
+code.
+This timestamp is compared by the server to its receive time
+stamp.
+If they differ by more than a small amount the request is
+rejected.
+This is done for two reasons.
+First, it makes simple
+replay attacks on the server, by someone who might be able to
+overhear traffic on your LAN, much more difficult.
+Second, it makes
+it more difficult to request configuration changes to your server
+from topologically remote hosts.
+While the reconfiguration facility
+will work well with a server on the local host, and may work
+adequately between time-synchronized hosts on the same LAN, it will
+work very poorly for more distant hosts.
+As such, if reasonable
+passwords are chosen, care is taken in the distribution and
+protection of keys and appropriate source address restrictions are
+applied, the run time reconfiguration facility should provide an
+adequate level of security.
+.Pp
+The following commands all make authenticated requests.
+.Bl -tag -width indent
+.It Xo Ic addpeer Ar peer_address
+.Op Ar keyid
+.Op Ar version
+.Op Cm prefer
+.Xc
+Add a configured peer association at the given address and
+operating in symmetric active mode.
+Note that an existing
+association with the same peer may be deleted when this command is
+executed, or may simply be converted to conform to the new
+configuration, as appropriate.
+If the optional
+.Ar keyid
+is a
+nonzero integer, all outgoing packets to the remote server will
+have an authentication field attached encrypted with this key.
+If
+the value is 0 (or not given) no authentication will be done.
+The
+.Ar version
+can be 1, 2 or 3 and defaults to 3.
+The
+.Cm prefer
+keyword indicates a preferred peer (and thus will
+be used primarily for clock synchronisation if possible).
+The
+preferred peer also determines the validity of the PPS signal - if
+the preferred peer is suitable for synchronisation so is the PPS
+signal.
+.It Xo Ic addserver Ar peer_address

+.Op Ar keyid
+.Op Ar version
+.Op Cm prefer
+.Xc
+Identical to the addpeer command, except that the operating
+mode is broadcast.
+In this case a valid key identifier and key are
+required.
+The
+.Ar peer_address
+parameter can be the broadcast
+address of the local network or a multicast group address assigned
+to NTP.
+If a multicast address, a multicast-capable kernel is
+required.
+.It Ic unconfig Ar peer_address ...
+This command causes the configured bit to be removed from the
+specified peer(s).
+In many cases this will cause the peer
+association to be deleted.
+When appropriate, however, the
+association may persist in an unconfigured mode if the remote peer
+is willing to continue on in this fashion.

+.Sh NAME
+.Nm ntpq
+.Nd standard NTP query program
+.Sh SYNOPSIS
+.Nm
+.Op Fl inp
+.Op Fl c Ar command
+.Op Ar host ...
+.Sh DESCRIPTION
+The
+.Nm
+utility program is used to query NTP servers
+which implement the recommended NTP mode 6 control message format
+about current state and to request changes in that state.
+The
+program may be run either in interactive mode or controlled using
+command line arguments.
+Requests to read and write arbitrary
+variables can be assembled, with raw and pretty-printed output
+options being available.
+.Nm
+can also obtain and print a
+list of peers in a common format by sending multiple queries to the
+server.
+.Pp
+If one or more request options is included on the command line
+when
+.Nm
+is executed, each of the requests will be sent
+to the NTP servers running on each of the hosts given as command
+line arguments, or on localhost by default.
+If no request options
+are given,
+.Nm
+will attempt to read commands from the
+standard input and execute these on the NTP server running on the
+first host given on the command line, again defaulting to localhost
+when no other host is specified.
+.Nm
+will prompt for
+commands if the standard input is a terminal device.
+.Pp
+.Nm
+uses NTP mode 6 packets to communicate with the
+NTP server, and hence can be used to query any compatible server on
+the network which permits it.
+Note that since NTP is a UDP protocol
+this communication will be somewhat unreliable, especially over
+large distances in terms of network topology.
+.Nm
+makes
+one attempt to retransmit requests, and will time requests out if
+the remote host is not heard from within a suitable timeout
+time.
+.Pp
+For examples and usage, see the
+.Qq "NTP Debugging Techniques"
+page
+(available as part of the HTML documentation
+provided in
+.Pa /usr/share/doc/ntp ) .
+.Pp
+The following options are available:
+.Bl -tag -width indent
+.It Fl c
+The following argument is interpreted as an interactive format
+command and is added to the list of commands to be executed on the
+specified host(s).
+Multiple
+.Fl c
+options may be given.
+.It Fl i
+Force
+.Nm
+to operate in interactive mode.
+Prompts
+will be written to the standard output and commands read from the
+standard input.
+.It Fl n
+Output all host addresses in dotted-quad numeric format rather
+than converting to the canonical host names.
+.It Fl p
+Print a list of the peers known to the server as well as a
+summary of their state.
+This is equivalent to the
+.Ic peers
+interactive command.
+.El
+.Pp
+Specifying a
+command line option other than
+.Fl i
+or
+.Fl n
+will
+cause the specified query (queries) to be sent to the indicated
+host(s) immediately.
+Otherwise,
+.Nm
+will attempt to read
+interactive format commands from the standard input.
+.Ss "Internal Commands"
+Interactive format commands consist of a keyword followed by zero
+to four arguments.
+Only enough characters of the full keyword to
+uniquely identify the command need be typed.
+The output of a
+command is normally sent to the standard output, but optionally the
+output of individual commands may be sent to a file by appending a
+.Ql \&> ,
+followed by a file name, to the command line.
+A
+number of interactive format commands are executed entirely within
+the
+.Nm
+program itself and do not result in NTP mode 6
+requests being sent to a server.
+These are described following.
+.Bl -tag -width indent
+.It Ic \&? Op Ar command_keyword
+.It Ic help Op Ar command_keyword
+A
+.Ql \&?
+by itself will print a list of all the command
+keywords known to this incarnation of
+.Nm .
+A
+.Ql \&?
+followed by a command keyword will print function and usage
+information about the command.
+This command is probably a better
+source of information about
+.Nm
+than this manual
+page.
+.It Xo Ic addvars
+.Ar variable_name Ns Op = Ns Ar value ...
+.Xc
+.It Ic rmvars Ar variable_name ...
+.It Ic clearvars
+The data carried by NTP mode 6 messages consists of a list of
+items of the form
+.Ql variable_name=value ,
+where the
+.Ql =value
+is ignored, and can be omitted,
+in requests to the server to read variables.
+.Nm
+maintains an internal list in which data to be included in control
+messages can be assembled, and sent using the
+.Ic readlist
+and
+.Ic writelist
+commands described below.
+The
+.Ic addvars
+command allows variables and their optional values to be added to
+the list.
+If more than one variable is to be added, the list should
+be comma-separated and not contain white space.
+The
+.Ic rmvars
+command can be used to remove individual variables from the list,
+while the
+.Ic clearlist   
+command removes all variables from the
+list.
+.It Ic authenticate Cm yes | Cm no
+Normally
+.Nm
+does not authenticate requests unless
+they are write requests.
+The command
+.Ql authenticate yes
+causes
+.Nm
+to send authentication with all requests it
+makes.
+Authenticated requests causes some servers to handle
+requests slightly differently, and can occasionally melt the CPU in
+fuzzballs if you turn authentication on before doing a
+.Ic peer
+display.
+.It Ic cooked
+Causes output from query commands to be "cooked", so that
+variables which are recognized by
+.Nm
+will have their
+values reformatted for human consumption.
+Variables which
+.Nm
+thinks should have a decodable value but didn't are
+marked with a trailing
+.Ql \&?  .
+.It Xo Ic debug
+.Cm more |
+.Cm less |
+.Cm off
+.Xc
+Turns internal query program debugging on and off.
+.It Ic delay Ar milliseconds
+Specify a time interval to be added to timestamps included in
+requests which require authentication.
+This is used to enable
+(unreliable) server reconfiguration over long delay network paths
+or between machines whose clocks are unsynchronized.
+Actually the
+server does not now require timestamps in authenticated requests,
+so this command may be obsolete.
+.It Ic host Ar hostname
+Set the host to which future queries will be sent.
+Hostname may
+be either a host name or a numeric address.
+.It Ic hostnames Cm yes | Cm no
+If
+.Cm yes
+is specified, host names are printed in
+information displays.
+If
+.Cm no
+is specified, numeric
+addresses are printed instead.
+The default is
+.Cm yes ,
+unless
+modified using the command line
+.Fl n
+switch.
+.It Ic keyid Ar keyid
+This command allows the specification of a key number to be
+used to authenticate configuration requests.
+This must correspond
+to a key number the server has been configured to use for this
+purpose.
+.It Xo Ic ntpversion
+.Cm 1 |
+.Cm 2 |
+.Cm 3 |
+.Cm 4
+.Xc
+Sets the NTP version number which
+.Nm
+claims in
+packets.
+Defaults to 3, Note that mode 6 control messages (and
+modes, for that matter) didn't exist in NTP version 1.
+There appear
+to be no servers left which demand version 1.
+.It Ic quit
+Exit
+.Nm .
+.It Ic passwd
+This command prompts you to type in a password (which will not
+be echoed) which will be used to authenticate configuration
+requests.
+The password must correspond to the key configured for
+use by the NTP server for this purpose if such requests are to be
+successful.
+.It Ic raw
+Causes all output from query commands is printed as received
+from the remote server.
+The only formating/interpretation done on
+the data is to transform nonascii data into a printable (but barely
+understandable) form.
+.It Ic timeout Ar milliseconds
+Specify a timeout period for responses to server queries.
+The
+default is about 5000 milliseconds.
+Note that since
+.Nm
+retries each query once after a timeout, the total waiting time for
+a timeout will be twice the timeout value set.
+.El
+.Ss Control Message Commands
+Each peer known to an NTP server has a 16 bit integer association
+identifier assigned to it.
+NTP control messages which carry peer
+variables must identify the peer the values correspond to by
+including its association ID.
+An association ID of 0 is special,
+and indicates the variables are system variables, whose names are
+drawn from a separate name space.
+.Pp
+Control message commands result in one or more NTP mode 6
+messages being sent to the server, and cause the data returned to
+be printed in some format.
+Most commands currently implemented send
+a single message and expect a single response.
+The current
+exceptions are the peers command, which will send a preprogrammed
+series of messages to obtain the data it needs, and the mreadlist
+and mreadvar commands, which will iterate over a range of
+associations.
+.Bl -tag -width indent
+.It Ic associations
+Obtains and prints a list of association identifiers and peer
+statuses for in-spec peers of the server being queried.
+The list is
+printed in columns.
+The first of these is an index numbering the
+associations from 1 for internal use, the second the actual
+association identifier returned by the server and the third the
+status word for the peer.
+This is followed by a number of columns
+containing data decoded from the status word.
+See the peers command
+for a decode of the
+.Sq condition
+field.
+Note that the data
+returned by the
+.Ic associations
+command is cached internally
+in
+.Xr ntpq 8  .
+The index is then of use when dealing with stupid
+servers which use association identifiers which are hard for humans
+to type, in that for any subsequent commands which require an
+association identifier as an argument, the form of index may be
+used as an alternative.
+.It Xo Ic clockvar Op Ar assocID
+.Oo
+.Ar variable_name Ns Op = Ns Ar value ...
+.Oc
+.Ar ...
+.Xc
+.It Xo Ic cv Op Ar assocID
+.Oo
+.Ar variable_name Ns Op = Ns Ar value ...
+.Oc
+.Ar ...
+.Xc
+Requests that a list of the server's clock variables be sent.
+Servers which have a radio clock or other external synchronization
+will respond positively to this.
+If the association identifier is
+omitted or zero the request is for the variables of the
+.Sq system clock
+and will generally get a positive response from all
+servers with a clock.
+If the server treats clocks as pseudo-peers,
+and hence can possibly have more than one clock connected at once,
+referencing the appropriate peer association ID will show the
+variables of a particular clock.
+Omitting the variable list will
+cause the server to return a default variable display.
+.It Ic lassociations
+Obtains and prints a list of association identifiers and peer
+statuses for all associations for which the server is maintaining
+state.
+This command differs from the
+.Ic associations
+command
+only for servers which retain state for out-of-spec client
+associations (i.e., fuzzballs).
+Such associations are normally
+omitted from the display when the
+.Ic associations
+command is
+used, but are included in the output of
+.Ic lassociations .
+.It Ic lpassociations
+Print data for all associations, including out-of-spec client
+associations, from the internally cached list of associations.
+This
+command differs from
+.Ic passociations
+only when dealing with
+fuzzballs.
+.It Ic lpeers
+Like R peers, except a summary of all associations for which
+the server is maintaining state is printed.
+This can produce a much
+longer list of peers from fuzzball servers.
+.It Ic mreadlist Ar assocID Ar assocID
+.It Ic mrl Ar assocID Ar assocID
+Like the
+.Ic readlist
+command, except the query is done
+for each of a range of (nonzero) association IDs.
+This range is
+determined from the association list cached by the most recent
+.Ic associations
+command.
+.It Xo Ic mreadvar Ar assocID Ar assocID
+.Oo
+.Ar variable_name Ns Op = Ns Ar value ...
+.Oc
+.Xc
+.It Xo Ic mrv Ar assocID Ar assocID
+.Oo
+.Ar variable_name Ns Op = Ns Ar value ...
+.Oc
+.Xc
+Like the
+.Ic readvar
+command, except the query is done for
+each of a range of (nonzero) association IDs.
+This range is
+determined from the association list cached by the most recent
+.Ic associations
+command.
+.It Ic opeers
+An old form of the
+.Ic peers
+command with the reference ID
+replaced by the local interface address.
+.It Ic passociations
+Displays association data concerning in-spec peers from the
+internally cached list of associations.
+This command performs
+identically to the
+.Ic associations
+except that it displays
+the internally stored data rather than making a new query.
+.It Ic peers
+Obtains a current list peers of the server, along with a
+summary of each peer's state.
+Summary information includes the
+address of the remote peer, the reference ID (0.0.0.0 if this is
+unknown), the stratum of the remote peer, the type of the peer
+(local, unicast, multicast or broadcast), when the last packet was
+received, the polling interval, in seconds, the reachability
+register, in octal, and the current estimated delay, offset and
+dispersion of the peer, all in milliseconds.
+The character in the left margin indicates the fate of this
+peer in the clock selection process.
+Following is a list of these
+characters, the pigeon used in the
+.Ic rv
+command, and a short
+explanation of the condition revealed.
+.Bl -tag -width indent
+.It space
+.Pq reject
+The peer is discarded as unreachable, synchronized to this
+server (synch loop) or outrageous synchronization distance.
+.It x
+.Pq falsetick
+The peer is discarded by the intersection algorithm as a
+falseticker.
+.It \&.
+.Pq excess
+The peer is discarded as not among the first ten peers sorted
+by synchronization distance and so is probably a poor candidate for
+further consideration.
+.It \&-
+.Pq outlyer
+The peer is discarded by the clustering algorithm as an
+outlyer.
+.It \&+
+.Pq candidate
+The peer is a survivor and a candidate for the combining
+algorithm.
+.It \&#
+.Pq selected
+The peer is a survivor, but not among the first six peers
+sorted by synchronization distance.
+If the association is ephemeral,
+it may be demobilized to conserve resources.
+.It \&*
+.Pq peer
+The peer has been declared the system peer and lends its
+variables to the system variables.
+.It o
+.Pq (pps.peer)
+The peer has been declared the system peer and lends its
+variables to the system variables.
+However, the actual system
+synchronization is derived from a pulse-per-second (PPS) signal,
+either indirectly via the PPS reference clock driver or directly
+via kernel interface.

+.Pp
+The
+.Va flash
+variable is a valuable debugging aid.
+It
+displays the results of the original sanity checks defined in the
+NTP specification RFC-1305 and additional ones added in NTP Version
+4.
+There are eleven tests called
+.Sy TEST1
+through
+.Sy TEST11 .
+The tests are performed in a certain order
+designed to gain maximum diagnostic information while protecting
+against accidental or malicious errors.
+The
+.Va flash
+variable
+is first initialized to zero.
+If after each set of tests one or
+more bits are set, the packet is discarded.
+.Pp
+Tests
+.Sy TEST4
+and
+.Sy TEST5
+check the access
+permissions and cryptographic message digest.
+If any bits are set
+after that, the packet is discarded.
+Tests
+.Sy TEST10
+and
+.Sy TEST11
+check the authentication state using Autokey
+public-key cryptography, as described in the
+.Sx Authentication Options
+section of
+.Xr ntp.conf 5 .
+If any bits are set
+and the association has previously been marked reachable, the
+packet is discarded; otherwise, the originate and receive
+timestamps are saved, as required by the NTP protocol, and
+processing continues.
+.Pp
+Tests
+.Sy TEST1

+are calculated and saved.
+Test
+.Sy TEST9
+checks the health of

+.Pp
+The
+.Va flash
+bits for each test read in increasing order
+from the least significant bit are defined as follows.
+.Bl -tag -width indent
+.It Sy TEST1
+Duplicate packet.
+The packet is at best a casual retransmission
+and at worst a malicious replay.

+The
+.Ic peers
+command is non-atomic and may occasionally result in
+spurious error messages about invalid associations occurring and
+terminating the command.
+The timeout time is a fixed constant,
+which means you wait a long time for timeouts since it assumes sort
+of a worst case.
+The program should improve the timeout estimate as
+it sends queries to a particular host, but doesn't.

+.Op Ar server
+.Sh DESCRIPTION
+.Nm
+determines where a given Network Time Protocol (NTP) server gets
+its time from, and follows the chain of NTP servers back to their
+master time source.
+If given no arguments, it starts with
+.Dq localhost .
+.Pp
+Here is an example of the output from
+.Nm :
+.Bd -literal
+% ntptrace
+localhost: stratum 4, offset 0.0019529, synch distance 0.144135
+server2ozo.com: stratum 2, offset 0.0124263, synch distance 0.115784
+usndh.edu: stratum 1, offset 0.0019298, synch distance 0.011993, refid 'WWVB'
+.Ed
+.Pp
+On each line, the fields are (left to right): the host name, the
+host stratum,
+the time offset between that host and the local host
+(as measured by
+.Nm ;
+this is why it is not always zero for
+.Dq localhost ) ,
+the host
+synchronization distance,
+and (only for stratum-1 servers) the reference clock ID.  All times
+are given in seconds.
+Note that the stratum is the server hop count to the primary source,
+while the synchronization distance is the estimated error
+relative to the primary source.
+These terms are precisely defined in RFC 1305.
+.Pp
+The following options are available:
+.Bl -tag -width indent
+.It Fl d
+Turn on some debugging output.
+.It Fl n
+Turn off the printing of host names; instead, host IP addresses
+are given.  This may be necessary if a nameserver is down.
+.It Fl r Ar retries
+Set the number of retransmission attempts for each host; the default is 5.
+.It Fl t Ar timeout
+Set the retransmission timeout (in seconds); the default is 2.
+.It Fl v
+Print verbose information about the NTP servers.

+.Sh NAME
+.Nm pccardc
+.Nd PC-CARD (PCMCIA) management and monitoring tool
+.Sh SYNOPSIS
+.Nm
+.Ar subcommand
+.Op Ar arg ...
+.Sh DESCRIPTION
+.Nm
+controls PC-CARD slots and configures and displays information about PCMCIA cards.
+.Nm
+understands the following subcommands:
+.Pp
+.Bl -tag -width pccardmem -compact
+.It Ic beep
+Set beep type
+.It Ic dumpcis
+Print card CIS(s)
+.It Ic enabler
+Device driver enabler
+.It Ic help
+Print command summary
+.It Ic pccardmem
+Allocate memory for pccard driver
+.It Ic power
+Power on/off slots and leaves them disabled
+.It Ic rdattr
+Read attribute memory
+.It Ic rdmap
+Read pcic mappings
+.It Ic rdreg
+Read pcic register
+.It Ic wrattr
+Write byte to attribute memory
+.It Ic wrreg
+Write pcic register
+.El
+.Bl -enum
+.It
+.Ic beep Ar beep_mode
+.Pp
+Specifies the sound made upon card insertion or removal.
+This subcommand corresponds to
+.Va pccard_beep
+in
+.Xr rc.conf 5 .
+Allowed values for
+.Ar beep_mode
+are:
+.Pp
+.Bl -tag -width Ds -compact
+.It Li 0
+silent mode
+.It Li 1
+simple beep mode
+.It Li 2
+melody mode
+.El
+.It
+.Ic dumpcis
+.Op Ar slot
+.Pp
+Displays
+.Em CIS
+(Card Information Structure) tuple in EEPROM of a PC-CARD card.
+.Ar Slot
+specifies which slot to read.
+When no option is supplied, it displays
+the CIS of all of the available cards.
+.It
+.Ic enabler Ar slot driver
+.Op Fl m Ar card addr size
+.Op Fl a Ar iobase
+.Op Fl i Ar irq
+.Pp
+This is a "point enabler" which can be used to set
+parameters manually to enable a card when
+.Xr pccardd 8
+cannot allocate drivers to a PC-CARD card properly.
+Specify a PC-CARD slot in
+.Ar slot
+and a device name (such as "ed0" or "sio2") in
+.Ar driver ,
+along with some or all of the following options:
+.Bl -tag -width Ds
+.It Fl m Ar card addr size
+maps the shared-memory window of the card to host address.
+.Ar card
+is the starting address of shared-memory (hex) in the card's address space,
+.Ar addr
+is the address (hex) to map the memory to in the computer's address space, and
+.Ar size
+is the size of memory window (kb).
+.It Fl a Ar iobase
+.Ar iobase
+specifies the port a number to be mapped to the I/O window (hex)
+.It Fl i Ar irq
+.Ar irq
+specifies the IRQ (decimal from 1 to 15) the card will use for interrupts.
+.El
+.Pp
+For example,
+.Bd -literal
+	enabler 0 ed0 -m 2000 d4000 16 -a 300 -i 3
+.Ed
+.Pp
+assigns the card in slot zero to the first NE2000 ethernet card driver at
+port 0x300 and IRQ 3,
+mapping the 16KB memory region at 0x2000 in the card to 0xd4000.
+.Pp
+This allows use of some unrecognized cards with broken CIS tuples,
+and is also useful for testing a card that has not yet reported.
+However, beware that it frequently cannot recognize new cards properly.
+.It
+.Ic help
+.Pp
+Prints help for
+.Nm .
+.It
+.Ic pccardmem Ar addr
+.Pp
+Specifies the host address using PC-CARD controller(PCIC)
+will use to map cards to.
+Because the PCIC needs a contiguous 16KB memory, and most machines
+have other ROMs or devices at other places in the ISA I/O memory
+address range, generally you can only use the following four addresses:
+.Pp
+.Bl -tag -width 0xd0000 -compact
+.It Ar 0xd0000
+0xd0000-0xd3fff (default)
+.It Ar 0xd4000
+0xd4000-0xd7fff
+.It Ar 0xd8000
+0xd8000-0xdbfff
+.It Ar 0xdc000
+0xdc000-0xdffff
+.El
+.Pp
+You can use "DEFAULT" instead of 0xd0000.
+This subcommand corresponds to
+.Va pccard_mem
+in
+.Xr rc.conf 5 .
+.It
+.Ic power Ar slot power_mode
+.Pp
+Changes the state of the power supply of the card in the specified
+.Ar slot :
+.Pp
+.Bl -tag -width Ds
+.It Li 0
+Turn off a power supply.
+If a card becomes unstable when it is removed at
+activate state,
+this can force it into inactive state first and remove it safely.
+The slot will remain disabled until you eject the card with the system
+running or reenable the card with another
+.Ic pccardc power
+power command.
+The slot will even remain disabled when you suspend and resume the
+computer.
+.It Li 1
+Turn on a power supply and set it into active state
+(the system treats the card as if it was just inserted).
+.El
+.Pp
+.It
+.Ic rdattr Ar slot offs length
+.Pp
+Prints a hex dump
+.Ar length
+bytes long of the EEPROM of the card in slot
+.Ar slot
+starting at
+.Ar offs .
+All parameters are in hex.
+.It
+.Ic rdmap
+.Op Ar slot
+.Pp
+Displays where the four memory windows and two I/O windows of a PC-CARD slot
+are mapped to on the host.
+If
+.Ar slot
+is not supplied, it displays the information for all of slots in the system.
+.It
+.Ic rdreg
+.Op Ar slot
+.Pp
+Displays the 64 registers of the card in
+.Ar slot
+(all slots by default).
+.It
+.Ic wrattr Ar slot offs value
+.Pp
+Writes a single byte to the card's EEPROM at
+an offset address from the top specified in
+.Ar offs
+(hex),
+with a value specified in
+.Ar value
+(hex).
+This is preserved after the card is removed.
+.It
+.Ic wrreg Ar slot reg value
+.Pp
+Writes a register of a PC-CARD.
+Specify a PC-CARD slot number in
+.Ar slot ,
+a register number in
+.Ar reg
+(hex) and
+a value in
+.Ar value
+(hex).

+.Sh NAME
+.Nm pccard.conf
+.Nd
+.Xr pccardd 8
+configuration file
+.Sh DESCRIPTION
+The
+.Nm
+file is the configuration file for the
+.Xr pccardd 8
+PC-CARD slot management daemon.
+It provides information to allow card
+identification, and the matching of drivers (along
+with driver resources) to the PC-CARD cards.
+.Pp
+There are four basic elements within the configuration file;
+An optional
+.Em "resource pool"
+preceding the other sections,
+and one or more
+.Em "card identifiers" ,
+and
+.Em "device instances" .
+The latter two may appear in any order, and may be
+interspersed as desired.
+.Pp
+The
+.Pa /etc/pccard.conf
+file is included from the file
+.Pa /etc/defaults/pccard.conf ,
+which contains the default resource pool settings and
+pccard identifiers database.
+The user specific configuration can be specified in
+.Pa /etc/pccard.conf
+when the user wishes to override these defaults and/or
+add additional entries.
+.Pp
+Each PC-CARD card contains configuration tuples that provide
+the manufacturer and card version; these are used
+to identify the card specification in the configuration
+file, and from this find a driver that can be used to
+interface to the particular card.
+There is a many-to-one mapping
+between cards to drivers i.e a single driver may interface to
+multiple types of cards.
+To aid this, card parameters may be
+specified separately from the driver to initialize the card or
+extract (in the case of a network card) an Ethernet address.
+.Pp
+Once a driver is allocated to a card, it stays
+allocated to that particular card.
+However, multiple instances of the same type of driver can be
+configured, so that if two cards are plugged in that map to a
+similar type of driver, other driver instances of the same name
+can be configured.
+.Pp
+The
+.Em insert
+and
+.Em remove
+commands allow a shell command line to be executed.
+The command to be executed is the rest of the line after
+the keyword.
+The line can be continued using a backslash.
+A simple
+macro substitution allows the current kernel device name
+.Em ( $device )
+and
+network card Ethernet address
+.Em ( $ether )
+to be inserted into the command line.
+.Xr pccardd 8
+uses the
+.Xr system 3
+subroutine to execute the command line.
+.Pp
+.Xr pccardd 8
+will use syslog to announce the insertion and removal of cards.
+It uses either the string set by the
+.Em logstr
+command, or the manufacturer and card version strings if none has
+been set.
+.Pp
+Numeric values may be expressed as octal, hex or decimal.
+If a decimal number has
+.Em k
+or
+.Em K
+appended to it, the value is multiplied by 1024. Names may be
+quoted using double quotes if spaces are required.
+A hash character comments out the rest of the line.
+.Ss "Resource pool"
+The (optional) section specifies a pool of system resources
+such as ISA bus memory address space, Input/Output ports and
+interrupt request numbers.
+This resource pool is used
+to allocate address space and interrupt numbers dynamically
+according to the requirements specified in each driver
+description.
+.Pp
+The syntax of the resources is as follows:
+.Pp
+.Dl io Ar start - end ...
+.Dl memory Ar address size ...
+.Dl irq Ar irq-number ...
+.Pp
+Each of the statements define I/O, memory or IRQ
+blocks that can be used to allocate to drivers when
+they are initialized.
+.Pp
+The syntax of the debuglevel parameter:
+.Pp
+.Dl debuglevel Ar level
+.Pp
+Multiple lines of any of the above statements may be
+present to allow separate blocks of each resource to be
+defined.
+.Ss "Card Identifiers"
+The syntax for card identifiers is:
+.Pp
+.Dl card Ar manufacturer version [ add_info1 [ add_info2 ]]
+.Dl config Ar index driver interrupt [ flags ]
+.Dl ether Ar offset
+.Dl reset Ar time
+.Dl iosize Ar size
+.Dl memsize Ar size
+.Dl insert Ar command
+.Dl remove Ar command
+.Dl logstr Ar string
+.Pp
+The first line is mandatory;
+the latter statements are optional and can appear in
+any order.
+There may be multiple
+.Em config
+lines.
+The
+.Em card
+parameters are the Manufacturer name, card version and
+additional information add_info1, add_info2 that
+is used to match the values from the card's CIS memory.
+These parameter can be described in extended regular expression
+.Xr regex 3
+if the string is enclosed by '/' like "/.*/".
+Each of the expressions is evaluated with a character '^' at top.
+.Pp
+The
+.Em config
+parameters select the particular card's configuration index
+from the range available in the card's CIS, the driver that
+is to be associated with this configuration, and the interrupt
+level (if any) to be assigned.
+An optional set of flags may
+be assigned.
+In
+.Ar index ,
+specify either ``auto'' or ``default'' or the range available in the card's CIS.
+``auto'' allows to allocate resources automatically with information
+from the CIS and status of using I/O resources.
+.Pp
+The optional
+.Em ether
+keyword is used when network cards have their physical Ethernet address
+located within the attribute memory of the card.
+The parameter of this
+statement indicates the offset within the attribute memory of the
+Ethernet address.
+This value can be used within insert/remove
+commands using the
+.Em $ether
+macro.
+.Pp
+The optional
+.Em reset
+keyword specifies reset duration at a card insertion in
+.Ar time
+milliseconds.
+Default is 100msec.
+.Pp
+.Em iosize
+and
+.Em memsize
+keywords are used with cards whose resources such as I/O ports and
+shared memory block are not specified in the CIS tuple.
+.Pp
+The
+.Em insert
+and
+.Em remove
+sections allow shell commands to be specified that are executed
+when the card is inserted or removed.
+Multiple
+.Em insert
+and
+.Em remove
+commands are allowed, and they are executed in the order they
+are listed.
+.Pp
+The
+.Em logstr
+command allows the user to set the string to be logged when this card is
+inserted or removed.
+If
+.Em logstr
+isn't specified, then the manufacturer and
+card version strings from the CIS are used to synthesize the string issued.
+.Ss "Wildcard entries"
+Following two wildcard entries of card identifiers are available
+for generic type of the cards:
+.Pp
+.Dl generic serial
+.Dl generic fixed_disk
+.Pp
+The keyword
+.Em serial
+matches ``Functional ID: Serial port/modem'' and
+.Em fixed_disk
+matches ``Fixed disk card''.
+The syntax is the same of
+.Em "card identifiers"
+but used ``generic'' instead of ``card'' in the first line.
+These are in the last of
+.Nm
+because unmatched cards with the other
+.Em card
+entries can match these entries secondly.
+The alias ``function'' can be used instead of ``generic'' because of
+the historical reason.

+.Sh NAME
+.Nm pccardd
+.Nd PC-CARD (PCMCIA) management daemon
+.Sh SYNOPSIS
+.Nm
+.Op Fl d
+.Op Fl v
+.Op Fl z
+.Op Fl i Ar IRQ
+.Op Fl I
+.Op Fl f Ar configfile
+.Sh DESCRIPTION
+.Nm Pccardd
+is normally started at boot time, and manages the insertion
+and removal of PC-CARD cards.
+.Pp
+When started,
+.Nm
+will read the configuration file (default name
+.Pa /etc/defaults/pccard.conf
+which includes
+.Pa /etc/pccard.conf
+as the user configuration file)
+and scans the available PC-CARD slots for cards.
+.Nm Pccardd
+then waits for
+.Em "card events" ,
+such as the insertion of a new card or the removal
+of a card.
+.Pp
+When a card is inserted, the following
+actions are taken:
+.Bl -enum
+.It
+The kernel driver detects the card insertion and applies
+power to the card.
+.It
+.Nm Pccardd
+reads the
+.Em CIS
+data from the attribute memory of the card, and uses
+the manufacturer name and card version to match
+the card description in the configuration file.
+.It
+Once matched, a driver is allocated.
+.It
+Once a free driver and device instance is located,
+.Nm
+will (if required) allocate resources such as an ISA memory
+block and Input/Output ports from a common pool.
+.It
+The PC-CARD slot is configured with the I/O and memory
+contexts allocated, and the kernel driver is attached to
+this card.
+.It
+If the attach succeeds, then specific shell commands
+may be executed to configure the device, such as
+.Xr ifconfig 8
+to set up a network interface.
+Separate commands may be specified
+for each card, driver or device, and are executed in that order.
+.El
+.Pp
+When
+.Nm
+detects that a card has been removed, the following sequence occurs:
+.Bl -enum
+.It
+The shell commands associated with card removal are executed.
+These
+are intended to reset any device associated with the removed card.
+Separate commands may exist for card, driver and device instances.
+.It
+The PC-CARD slot resources are freed.
+.El
+.Pp
+Once a card/driver instance is configured, the resources
+bound to that instance are remembered, and if the card is removed
+and reinserted, the same driver is allocated.
+The primary reason
+is that once a driver is associated with a card, the
+driver's
+.Fn probe
+routine has been called, and this usually causes driver specific
+data areas to be initialized with the I/O ports or memory resources
+allocated to the card.
+Most drivers are not designed to be
+disassociated from the hardware and then reassociated with different
+parameters.
+This will change significantly when loadable kernel
+modules are supported.
+.Pp
+SIGHUP causes
+.Nm
+to reload the configuration files.
+.Pp
+The start options understood by
+.Nm
+are:
+.Bl -tag -width Ds
+.It Fl d
+Do not run as a daemon, but run in the foreground and
+display error messages.
+.It Fl v
+After reading the configuration file, print out a summary
+of it.
+.It Fl z
+Delays running as a daemon until after the cards have been probed and attached.
+.It Fl I
+Don't get a list of free IRQs from kernel.
+.It Fl i Ar IRQ
+Configures an available IRQ.  It overrides the "irq" line in
+.Pa /etc/defaults/pccard.conf
+and
+.Pa /etc/pccard.conf .
+.It Fl f Ar configfile
+Specifies a different configuration file to be used
+in placed of the default file
+.Pa /etc/defaults/pccard.conf .
+The file format is detailed in
+.Xr pccard.conf 5 ,
+and lists the PC-CARD cards recognized by
+.Nm ,
+and the kernel drivers and devices that are used to
+interface to the card.

+.Sh BUGS
+.Nm Pccardd
+can set up card parameters, but cannot guarantee that
+particular drivers can work with the card.
+.Pp
+Removing cards may cause problems if system resources
+have been associated with the card, such as network
+mounted filesystems.

+.Sh NAME
+.Nm pciconf
+.Nd diagnostic utility for the PCI bus
+.Sh SYNOPSIS
+.Nm
+.Fl l Op Fl v
+.Nm
+.Fl a Ar sel
+.Nm
+.Fl r Oo Fl b | h Oc Ar sel addr Ns Op : Ns Ar addr
+.Nm
+.Fl w Oo Fl b | h Oc Ar sel addr Op Ar value
+.Sh DESCRIPTION
+The
+.Nm
+command provides a command line interface to the functionality provided by
+.Pa /dev/pci Ns 's
+.Xr ioctl 2
+interface.
+With the
+.Fl l
+option, it lists all devices found by the boot probe in the following format:
+.Bd -literal
+foo0@pci0:4:0: class=0x010000 card=0x00000000 chip=0x000f1000 rev=0x01 hdr=0x00
+bar0@pci0:5:0: class=0x000100 card=0x00000000 chip=0x88c15333 rev=0x00 hdr=0x00
+none0@pci0:6:0: class=0x020000 card=0x00000000 chip=0x802910ec rev=0x00 hdr=0x00
+.Ed
+.Pp
+If the
+.Fl v
+option is supplied,
+.Nm
+will attempt to load the vendor/device information database, and print
+vendor, device, class and subclass identification strings for each device.
+.Pp
+The first column gives the
+device name, unit number, and
+.Ar selector .
+If there is no device configured in the kernel for the
+.Tn PCI
+device in question, the device name will be
+.Dq none .
+Unit numbers for unconfigured devices start at zero and are incremented for
+each unconfigured device that is encountered.  The
+.Ar selector
+is in a form which may directly be used for the other forms of the command.
+The second column is the class code, with the class byte printed as two
+hex digits, followed by the sub-class and the interface bytes.
+The third column gives the contents of the subvendorid register, introduced
+in revision 2.1 of the
+.Tn PCI
+standard.
+It is 0 for most current (2.0)
+.Tn PCI
+cards, but is supposed to be loaded with a unique card identification code
+in newly developed
+.Tn PCI
+cards.
+The field consists of the card ID in the upper
+half and the card vendor ID in the lower half of the value.
+.Pp
+The fourth column contains the chip device ID, which identifies the chip
+this card is based on.
+It consists of two fields, identifying the chip and
+its vendor, as above.
+The fifth column prints the chip's revision.
+The sixth column describes the header type.
+Currently assigned header types are 0 for all devices except
+.Tn PCI
+to
+.Tn PCI
+bridges, and 1 for such bridge chips.
+If the most significant bit
+of the header type register is set for
+function 0 of a
+.Tn PCI
+device, it is a
+.Em multi-function
+device, which contains several (similar or independent) functions on
+one chip.
+.Pp
+The
+.Fl l
+option is the only one available to non-root users.
+All other invocations of
+.Nm
+require a
+.Ar selector
+of the form
+.Li pci Ns Va bus Ns \&: Ns Va device
+(optionally followed by
+.Li \&: Ns Va function ) .
+A final colon may be appended and
+will be ignored; this is so that the first column in the output of
+.Nm
+.Fl l
+can be used without modification.  All numbers are base 10.
+.Pp
+With the
+.Fl a
+flag,
+.Nm
+determines whether any driver has been assigned to the device
+identified by
+.Ar selector .
+An exit status of zero indicates that the device has a driver;
+non-zero indicates that it does not.
+.Pp
+The
+.Fl r
+option reads a configuration space register at byte offset
+.Ar reg
+of device
+.Ar selector
+and prints out its value in hexadecimal.
+The optional second
+.Ar reg2
+specifies a range to read.
+The
+.Fl w
+option writes the
+.Ar value
+into a configuration space register at byte offset
+.Ar reg
+of device
+.Ar selector .
+For both operations, the flags
+.Fl b
+and
+.Fl h
+select the width of the operation;
+.Fl b
+indicates a byte operation, and
+.Fl h
+indicates a halfword (two-byte) operation.  The default is to read or
+write a longword (four bytes).
+.Sh ENVIRONMENT
+The PCI vendor/device information database is normally read from
+.Pa /usr/share/misc/pci_vendors .
+This path can be overridden by setting the environment variable
+.Ev PCICONF_VENDOR_DATABASE .
+.Sh SEE ALSO
+.Xr ioctl 2 ,
+.\" .Xr pci 4 ,
+.Xr kldload 8
+.Sh HISTORY
+The
+.Nm
+command appeared first in
+.Fx 2.2 .
+The
+.Fl a
+option was added for
+.Tn PCI
+KLD support in
+.Fx 3.0 .
+.Sh AUTHORS
+.An -nosplit
+The
+.Nm
+facility was written by
+.An Stefan Esser
+and
+.An Garrett Wollman .
+.Sh BUGS
+The
+.Fl b
+and
+.Fl h
+options are implemented in
+.Nm ,
+but not in the underlying
+.Xr ioctl 2 .
+.Pp
+It might be useful to give non-root users access to the
+.Fl a
+and
+.Fl r
+options.
+But only root will be able to execute a
+.Nm kldload
+to provide the device with a driver KLD, and reading of configuration space
+registers may cause a failure in badly designed
+.Tn PCI
+chips.

+Character Generator description			        (before it gets lost ..)
+--------------------------------------------------------------------------------
+
+The lower character generator is the default IBM character set II.
+
+The description of the higher character generator follows below. The
+character names are taken from the "Postscript Language Reference
+Manual", 2nd Edition, Fourth printing July 1991, pp 596.
+
+NOTE: The hex values here are NOT the values the character is identified
+      by in the emulator. The "physical" (vt220 character) to "logical"
+      (this table, character generator) conversion is done in the character
+      output routine by using the tables from file pcvt_tbl.h.
+
+The order of the characters is not regular and was largely influenced by
+the status of my brain while pixel-placing characters ....

+
+II.	Emulating Character Set Selection
+=========================================
+
+MDA/HCG/CGA:
+
+	just a partial emulation is done, because these boards don't allow
+	downloadable charactersets. some characters simply don't display
+	because they are not in the characterset roms on the video board.
+
+	if you want to change the mapping, have a look at the default tables
+	in pcvt_tbl.h.
+
+EGA/VGA:
+
+	these cards have provisions for downloadable charactersets and so
+	many vt220/vt320 charactersets are fully supported:
+
+		- US Ascii
+		- DEC Supplemental
+		- DEC Special Graphic
+		- DEC Technical
+		- ISO Latin-1
+		- Downloadable
+
+	when the emulator is started, it behaves initially similar to
+	the MDA/CGA/HCG method described above.
+
+	when a second (special) characterset for a given screen resolution
+	is loaded via the "loadfont" utility, the emulator detects this fact
+	and uses from then on extended tables to access the second charset
+	as an upper half 512 characterset in terms of ega/vga speak.
+
+	from this time on, vt220 downloadable fonts are usable.
+
+	the organization of this extended characterset is as follows:
+
+		0x00 ... 0x1f	C0 display function fonts
+		0x20 ... 0x3f	C1 display function fonts
+		0x40 ... 0x9f	fonts for DEC Supplemental, DEC Special
+				Graphic, DEC Technical and ISO Latin-1
+		0xa0 ... 0xff	VT220 Downloadable Font
+	
+	the mapping between vt220 charactersets and the charactersets inside
+	the ega/vga is done by tables found in the file pcvt_tbl.h.
+	
+	there is a MSDOS fonteditor called "EVAFONT" available on the
+	SIMTEL-20 archive, which i used to edit the character sets in the
+	distribution.

+II.	Special Keys Used To Change The General Runtime Functionality
+=====================================================================
+
+
+	To be consistent with XFfree86 2.0 Virtual Screen switching, it is
+	now also possible to switch screens by using:
+
+		CTRL - ALT - Fx , where x can be 1 ... No of screens compiled,
+		                  see the definition of PCVT_NSCREENS !
+
+
+	Virtual Screen/Terminal switching
+	---------------------------------
+
+		F9  or CTRL-ALT-F1	switches to screen 0
+		F10 or CTRL-ALT-F2	switches to screen 1
+		F11 or CTRL-ALT-F3	switches to screen 2
+		F12 or CTRL-ALT-F4	switches to screen 3
+		CTRL-ALT-F5		switches to screen 4
+		CTRL-ALT-F6		switches to screen 5
+		CTRL-ALT-F7		switches to screen 6
+		CTRL-ALT-F8		switches to screen 7
+		CTRL-ALT-F9		switches to screen 8
+		CTRL-ALT-F10		switches to screen 9
+		CTRL-ALT-F11		switches to screen 10
+		CTRL-ALT-F12		switches to screen 11
+
+		(see also ALT-F12 below)
+
+
+	ALT-F9	Function key labels ON / OFF
+	------------------------------------
+
+		this key is only operational, when in HP/VT mode, see F11
+
+		ALT-F9 toggles between function key labels displayed or not.
+
+		ON:  screen has either 25-3 = 22, 28-3 = 25 or 50-3 = 47 lines
+			2 lines fkey labels displayed
+			row/col display enabled
+			1 line status/load avg line
+
+		OFF: screen has either 25-3 = 22, 28-3 = 25 or 50-3 = 47 lines
+			no function key labels displayed
+			no row/col display
+			no status/load avg line
+
+		applicable escape sequences:
+
+			switch OFF:
+			ESC & j @	remove labels from screen
+
+			switch ON:			
+			ESC & j A	display system fkey labels
+			ESC & j B	display user fkey labels
+			ESC & j C	display current fkey labels
+
+		
+	ALT-F10	User / System Function key labels
+	-----------------------------------------
+
+		this key is only operational, when in HP/VT mode, see ALT-F11
+
+		ALT-F10 toggles between the display of user or system
+		function key labels
+
+		this key is only active if labels are toggled on via
+		the ALT-F9 function key
+		
+		screen has either 25-3 = 22, 28-3 = 25 or 50-3 = 47 lines
+			2 lines fkey labels displayed
+			row/col display enabled
+			1 line status/load avg line
+
+		
+		applicable escape sequences: (see above)
+		
+			ESC & j A	display system fkey labels
+			ESC & j B	display user fkey labels
+			ESC & j C	display current fkey labels
+
+
+	ALT-F11	Toggle between pure VT and HP-VT Emulation
+	--------------------------------------------------
+
+		This key switches between pure vt100/vt220 mode and
+		vt100/vt220 with hp-fkey-labels mode of operation.
+		this is not dependent of any screen resolution the
+		virtual consoles are in.
+
+		initially, after power on, all virtual screens are in
+		the pure vt-mode:
+
+		- the emulator does not execute any hp escape sequences
+		- the function key label lines are switched off
+		- no load average or status line is displayed
+		- no row / column counter is displayed
+		- no window number is displayed
+		- the full screen 25x80, 28x80 or 50x80 is usable
+		- ALT-F9 and ALT-F10 have no function
+
+		when toggled to the vt/hp mix of operation, the following
+		changes take place:
+
+		- the emulator executes the supported hp-esc sequences
+		- the function key labels are displayable depending
+		  on the state of ALT-F9/F10
+		- the load average is displayed
+		- the row / column counters are displayed
+		- the window number is displayed in the lower right corner
+		- in any screen resolution, the last 3 lines are lost,
+		  so one has a 22x80, 25x80 and 47x80 resolution
+		- F9 and F10 are operational.
+
+		when switching modes by means of ALT-F11, the following
+		changes to the current environment, the emulator may
+		be in, apply:
+
+		- the screen is cleared
+		- the cursor moves to the home position
+		- the scrolling region is reset to default
+
+		(this functionality is available via an ioctl)
+
+	ALT-F12	Cycle current screen
+	----------------------------
+
+		This key cycles through the display of the video
+		screens. on startup, screen 0 is displayed; with every
+		keypress of F12, the next screen is displayed, wrapping
+		from the maximum screen number back to screen 0.
+
+		(this functionality is available via an ioctl)	
+
+
+III.	Special Keys used to change the Runtime Functionality of a Page
+=======================================================================
+
+	when in mixed HP/VT mode, one has two types of function key labels
+	on screen, user function keys and system function keys.
+
+	this functionality is NOT available in pure VT220 mode !
+
+	the user function keys emit the below mentioned VT220 function-
+	key sequences. the labels can be reprogrammed by use of escape
+	sequences.
+
+	in system function key mode, several pre-programmed functions inside
+	the emulator can be toggled, currently implemented are:
+
+	- F1, if a chipset is detected for which 132 operation is supported,
+		F1 toggles between 80 columns and 132 columns.
+	- F2, does a soft reset of the emulator code
+ 	- F3, -/-
+	- F4, -/-
+	- F5, toggle the audible beep generation
+	- F6, toggle 7/8 bit char width 
+	- F7, toggle display functions. this means that control codes 
+	      in the range 0x00 to 0x1f are not EXECUTED by the emulator
+	      any longer, but displayed on the screen
+	- F8, toggle automatic cursor wraparound at end of line
+
+	these functions operate just for the selected screen
+
+
+IV.	Keyboard VT220 compatibility
+====================================
+
+	The following keys behave different as probably expected.
+
+	They were mapped to provide more VT220 compatibility.
+
+	To have F1-F8 emit something in HP-mode, you have to switch
+	to user function key labels by using ALT-F10 (see ALT-F10 above) !

+First of all, please read the file BugList in this directory !
+
+
+Can't get pcvt working on a ThinkPad
+===============================================================================
+
+Anyway, back to the keyboard.  The problem is that by default the
+ThinkPad uses PS/2 scan code mode.
+
+You can fix this by using an option and building a kernel, as shown
+below.
+
+] Just for the record, in case someone else is asking for this: Al's
+] confirmation that pcvt w/ PCVT_SCANSET=2 works for the ThinkPad:

+
+If one of the "lock" keys is pressed, LEDs do not get updated, keyboard hangs
+===============================================================================
+
+This entry used to be a long time in the BugList file, and i could never
+reproduce the problem. Today i got an explanation in german from someone
+owning such a keyboard, i'll try to translate:
+
+"This are old keyboards manufactured (~1985/1986) which manage their LED
+ setting only internally.
+ It is not possible to set the LEDs from the (main-) processor, if you
+ try, the keyboard processor hangs and the PC has to be reset by switching
+ power on and off, hard- and/or softreset does not work in this case.
+ Workaround: recompile pcvt with the LED update removed"
+
+In other words, define PCVT_NO_LED_UPDATE if you have such a beast!
+
+
+Cursor not visible anymore in 40 and 50 lines mode
+===============================================================================
+
+You have programmed an underline cursor in i.e. 28 line mode by doing
+"cursor -s 10 -e 12". Then you switch to 40 line mode using "scon -s 40".
+At this point the cursor is no longer visible because the 40 line font
+is only 10 pixels high and the cursor size is programmed with a value
+expressing its size from the top down and NOT from the bottom up!
+If anyone has a good idea how to solve this problem, please tell me!
+The only solution i see so far is having some sort of "generic" cursor
+sizes/descriptions (i.e. underline, rectangle, block) which are
+recalculated in case of a switch to another line size.
+
+
+386BSD port
+===============================================================================
+
+I don't have access to a 386BSD 0.1 machine anymore so the 386BSD pcvt is
+considered unsupported and will disappear in the future.
+
+386BSD support was dropped with release 3.20.
+
+
+Keyboard hangs after first update of keyboard LED's
+===============================================================================
+
+Define PCVT_NO_LED_UPDATE and recompile pcvt. (Or, get yourself a better
+keyboard. Some keyboards just don't work the documented way, this fact is
+"normally" masked by the manufacturers BIOS but unhides when one accesses
+the hardware directly.)
+
+
+Garbled screen when running vi
+===============================================================================
+
+When the terminal speed in the tty structure is set to low speeds (i.e. 1200
+Baud), pcvt shows a strange behaviour in some environments due to the changed
+screen update sequences from vi.
+
+Please check your shell startup files, /etc/ttys and /etc/gettytab and change
+the baudrate (i.e. by using stty(1)) to a higher value, i.e. 19200 Baud.
+
+Since i'm not a vi specialist, i never managed to find out wheter to blame
+vi or pcvt.
+
+
+Stty influences on the driver
+===============================================================================
+
+There used to be an entry in the BugList:
+
+	(printf with 9 x tab) printf "\n\t\t\t\t\t\t\t\t\tGotcha" works ok,
+	while one tab more: printf "\n\t\t\t\t\t\t\t\t\t\tGotcha" doesn't
+	work (it doesn't print Gotcha at column 80, but at column 131).
+
+This was solved some time ago:
+
+	On another note: if I use stty xtabs, the 'printf "\t\t\t\t\t\t\t" 
+	bug goes away. With stty xtabs the tab handling is done in the kernel.
+
+(See also below: "Vttest shows strange results")
+
+
+After running some graphics application, the cursor is stuck on the
+bottom line, though everything else appears well
+===============================================================================
+
+Though this might initially appear to be a driver problem, it's rather
+an application program's bogosity. The cursor update is done asynchron-
+ously (to gain output speed), but this cursor update is inhibited while
+an application has put a virtual terminal into ``graphics mode'' (i.e.,
+the application program tells the driver that it's now responsible for
+anything and all on this vty). This is notably the case while X11 is
+running.
+
+If the application fails to properly shut down itself, the terminal
+might be left in an undefined state. The driver stand no chance there,
+even if it could detect this bad status, since it doesn't know enough
+about each piece of hardware to deal with. One possibility is that
+the X server has been shot up and didn't get it to do its cleanups.
+Another case (which i've often noticed on my slow notebook) is, killing
+the Xserver is too slow for the (unfortunately hard-coded) 10-second
+timeout from xinit, so it's being aborted ridiculously. (``X server
+slow to shut down, sending KILL signal.'') This way, the state of
+damage might range from ``almost okay, but cursor is stuck'' up to
+a totally unusable machine (moon bitmap from xphoon still displayed,
+no keyboard responses, only network is working and can be used to
+shut down cleanly).
+If the state of damage is only minimal, you might try to run the pure
+X server on that vty again, and exit it with Ctrl-Alt-BkSpc. This might
+be a workaround.
+
+
+Vttest shows strange results
+===============================================================================
+
+Verify your stty "oxtabs" settings, it has to be "oxtabs", NOT "-oxtabs".
+Get yourself an original DEC terminal to verify vttest's output, i have
+until now not seen any (!) VTxxx clone, which does it right !!!
+
+
+VT220-like Keyboard Layout
+===============================================================================
+
+I have to say, i don't use it and i don't like it, so it's mostly unsupported
+and untested. Patches welcome!
+
+
+132-column mode
+===============================================================================
+
+There are known difficulties running pcvt in 132 column mode in conjunction
+with X. Switching to 132 column mode does not only depend on a given chipset,
+but on the board/manufacturers method of clock generation also. Even if your
+chipset is detected, there may be still a problem with your board and it's
+method of generating clocks. You may run in severe difficulties if your
+board has a programmable clock generator and you run X and you switch from
+132 col mode into X and back.
+
+I have currently no idea how to solve this, other than having a similar
+scheme as XFree86 applied to pcvt: Letting the user probe his board by using 
+SuperProbe and recompiling pcvt according to the result.
+
+I stumbled a bit deeper into this with my ELSA Winner 1000, which is equipped
+with a ICD2061 clock synthesizer chip. For 132 column mode to work properly,
+clock generator 2 must deliver 40 MHz to the S3 VGA chip, but this value has
+to be programmed or initialized. If this VGA board has ever been switched
+into 132 colums, i.e. in my case from a DOS program, it will continue to do
+so until X runs or the machine is power cycled. If that occurs, the clock
+generator 2 does contain nothing or garbage (in case of power cycling) or it
+does contain the value for the current resolution in X in case of having been
+in the X Server screen recently.
+
+The X Server reprograms the clock generator each time the server is entered,
+so the only thing to do is to reprogram the clock generator too when pcvt is
+entered. Until now i found no way of identifying the clock oscillator chip
+used, so an automatic clock switching seems to be a problem.
+
+
+NetBSD 0.9 and Xfree86 2.0
+===============================================================================
+
+To get the X server up and running on 0.9, you have to compile pcvt with
+PCVT_USL_VT_COMPAT disabled, otherwise X (and SuperProbe) will hang the
+video driver (not the whole machine !). This bug is reproducible but not
+found yet ...
+This does not apply to NetBSD-current, 386BSD and FreeBSD.
+
+
+X server ioctl compatibility:
+===============================================================================
+
+The compatibility X-Mode ioctl commands CONSOLE_X_MODE_ON and
+CONSOLE_X_MODE_OFF should not be used intermixed with the USL VT style
+commands on another virtual terminal. NB, that this situation could happen
+if you run an XFree86 2.0 server on one virtual terminal and attempt to
+run SuperProbe version 1.0 (as delivered with the XFree86 2.0 release)
+on another vty. SuperProbe is still using the old commands in order to
+gain IO privileges.
+Since the old commands cannot care for things like terminal switching,
+serious corruption could result from this, which need not to be detected
+immediately (i.e., apparently SuperProbe ran well). Known problems are
+font corruptions after the X server has been shut down later, or palette
+flickers in 1-second intervals due to an erroneously re-enabled screen
+saver.
+
+Once that SuperProbe has been fixed in its release to use the USL VT style
+commands, any support for the old CONSOLE_X_MODE_XXX commands will be
+eliminated.
+
+(Recent comment: SuperProbe 1.3 has been fixed. It will be delivered with
+XFree86 2.1.)
+
+
+How to set the foreground intensity to high on VGA mono screens:
+===============================================================================
+
+try to issue the command: "scon -p8,60,60,60", EXPERIMENT !!!
+
+
+How to change the color palette on VGA cards:
+===============================================================================
+	
+try out the following commands:
+
+	/usr/local/bin/scon -d/dev/ttyv0 -pblack:0,0,0 -pblue:20,20,40
+	/usr/local/bin/scon -d/dev/ttyv0 -pbrown:55,55,15 -plightgray:0,42,0
+	/usr/local/bin/scon -d/dev/ttyv1 -pblack:42,42,42 -pblue:60,60,60
+	/usr/local/bin/scon -d/dev/ttyv1 -pbrown:60,60,30 -plightgray:30,10,0
+	/usr/local/bin/scon -d/dev/ttyv2 -pblack:42,42,42 -pblue:63,63,63
+	/usr/local/bin/scon -d/dev/ttyv2 -pbrown:60,60,20 -plightgray:0,22,0
+	/usr/local/bin/scon -d/dev/ttyv3 -pblack:38,38,38 -pblue:63,63,63
+	/usr/local/bin/scon -d/dev/ttyv3 -pbrown:60,40,0 -plightgray:0,0,20
+
+	("scon -p default" resets the colors ...)
+
+
+I have the screensaver compiled in, but can't see any effect
+===============================================================================
+
+Don't forget to turn it on with the scon utility. E.g.,
+
+	scon -t 120
+
+sets the timeout to 2 minutes.
+
+
+Your Notebook uses the NumLock state to switch half of the keyboard into a
+numeric keypad
+===============================================================================
+
+Sigh, each time you leave "vi", your NumLock LED is on again and you
+get a "6" instead of "o"? Try
+
+	options  "PCVT_INHIBIT_NUMLOCK"
+
+this prevents applications from turning NumLock on/off (except the
+Xserver - but you want this).
+
+
+Your notebook significantly loses contrast when using pcvt
+===============================================================================
+
+Pcvt turns off the "high intensity" attribute bit internally (to enable
+the use of a 512-characters charset). Some notebooks hard-code the out-
+put intensity versus the character attribute though (i know it for a
+Cirrus Logic CL-GD610/620 chipset).
+
+As a quick & dirty workaround, you can reverse what pcvt did to the
+Attribute Controller. Do not hack pcvt_sup.c, instead patch your
+VGA registers during rc.local with the help of the vgaio utility:
+
+    echo "ar12=0f" | vgaio > /dev/null
+
+For the CL-GD610/620, i'm remapping some attribute registers and
+get a simple gray scale emulation with this (i.e., i DO NOT use
+the hack above):
+
+   eagle_id=`echo 'cr1f?' | vgaio | cut -dx -f2`
+   echo "sr 6 = $eagle_id" | vgaio > /dev/null	# enable extended regs
+   echo "sr d5 = 40" | vgaio       > /dev/null	# not inverse, enable
+						# color emulation
+   echo "ar0=0;ar1=9;ar2=12;ar3=1b;ar4=24;ar5=2d;ar6=36;ar7=3f"|vgaio>/dev/null
+   echo "ar8=0;ar9=9;ara=12;arb=1b;arc=24;ard=2d;are=36;arf=3f"|vgaio>/dev/null
+
+NOTE THAT THIS IS ONLY FROM EXPERIMENTS! There's no warranty that something
+like this wouldn't damage your screen/VGA!
+
+(If you have chipset documentation, you're lucky...)
+
+
+How to set the "LINES"-Environment variable for sh/csh:
+===============================================================================
+
+(Note: this is mostly obsoleted now since the driver properly generates
+SIGWINCH'es to notify applications about a changed screen size.)
+
+     first for the csh:
+
+	alias linesw scon -s \!^ \; setenv LINES \!^
+
+     now for the bash/ash/sh/bash users:
+
+	linesw()
+	{
+		scon -s $1
+		LINES=$1; export LINES
+	}

+
+The major contributors to pcvt are Brian and Joerg, pcvt would not be what it
+is without the help, the support and the code from Joerg:
+
+                            Brian Dunford-Shore           (brian@athe.wustl.edu)
+
+                            wrote parts of the EGA/VGA hardware handling and
+                            some of the more ugly aspects of the VT220.
+
+                            Joerg Wunsch        (joerg_wunsch@uriah.heep.sax.de)
+
+                            added ALL support for XFree86, the screensaver sub-
+                            system and support for FreeBSD (and much more ...).
+
+
+I have to thank the following people for their help, for beta-testing, bugfixes,
+code, keymaps, suggestions, hints, patience and too much more to mention:

+- The files "chardemo.vt" and "colors.vt" are taken from the MSDOS Kermit 
+  distribution and are redistributed with permission from Frank da Cruz.
+
+- cat chardemo.vt - displays all available character sets
+
+- cat colors.vt   - displays all available back/foreground color combinations
+
+- cat sgr.vt      - displays all possible graphic renditions
+
+- all other files are some VT100 animations collected over the time from
+  unkown sources, play them with playvt.
+
+- Playvt is a program to play an animation file on pcvt: because pcvt is
+  _much_ faster than an original VT100/VT220, it adds a programmable delay
+  for each character so one can enjoy smooth-running animations! :-)
+  There is no manpage available for playvt, just try to run playvt -? which
+  should give sufficient information. You have to empirically find out which
+  delay value fit's your needs!
+
+have fun!

+When I first saw this posted to rn, I tried to compile this on a machine 
+running BSD UNIX.  Much to my dissapointment, It said "unable to find
+/usr/include/termio.h" and thus it sat for a couple months.  I was able to
+compile it on a 3b5, but I didn't have a vt220 hooked up to it.  I was doing
+some unrelated work with ioctl calls and finally realized that it would not be
+too hard to convert it from System V to BSD.  It also looked kind of strange
+with the cursor on, so I turned this off.  To implement this, compile with
+the "-DCURFIX" flag in the Makefile.  
+I am working on a new version that uses curses and that would enable you to 
+change the file that your are working on without leaving the program.  
+I thought I'd post it as it is now, since it has a lot of uses right away.
+Imagine changing your favorite game to have objects that look like what they 
+are instead of the regular characters.  Also, I think people should post their
+own character sets, if they come up with some neat stuff. 
+             Please send any comments or suggestions to:

+.\" $FreeBSD$

+.Dd January 16, 2001
+.Dt FONTEDIT 1
+.Os
+.Sh NAME
+.Nm fontedit
+.Nd "edit fonts"
+.Sh SYNOPSIS
+.Nm
+.Ar file
+.Sh DESCRIPTION
+The
+.Nm
+utility is used to edit the down line reloadable character set (DRCS) of a
+.Tn VT220
+terminal.
+The editor has two display areas, one for displaying the
+entry currently being manipulated, and one for displaying the complete
+DRCS.
+Commands to the editor take the form of function keys.
+.Pp
+The
+.Nm
+utility
+takes one command line parameter, a
+.Ar file
+name.
+This file is used to save the character set.
+If the file exists when
+.Nm
+is invoked, it is read in to initialize the DRCS.
+The file is written to when
+.Nm
+exits.
+.Pp
+Commands to
+.Nm
+take the form of function keys.
+The current definitions are:
+.Bl -tag -width "Cursors"
+.It Ic HELP
+Display a help screen.
+.It Ic F6
+Turn the pixel under the cursor on.
+.It Ic F7
+Turn the pixel under the cursor off.
+.It Ic F13
+Clear the display area.
+.It Ic Find
+Save the current font in the font table.
+Update the DRCS display.
+.It Ic Select
+Extract the entry selected by the cursor in the DRCS display.
+.It Ic Prev
+Move the cursor to the previous entry in the DRCS display.
+.It Ic Next
+Move the cursor to the next entry in the DRCS display.
+.It Ic Insert
+Insert a blank line at the current cursor position.
+The bottom row is lost.
+.It Ic Remove
+Remove the row at the current cursor position.
+All rows below the
+current one are shifted up.
+.It Ic Cursors
+Move the cursor in the main display area.
+.El
+.Pp
+If the screen gets garbled, press
+.Aq control\-L .
+.Pp
+To exit
+.Nm ,
+press
+.Aq control\-D .
+The DRCS will be saved in
+.Ar file .
+To exit without saving the DRCS, hit interrupt (usually
+DEL).
+.Sh DIAGNOSTICS
+The
+.Nm
+utility
+will issue a warning when the entry being worked on is not saved, and
+some potentially destructive command, like
+.Ic Select
+is used.
+To
+override the warning message, immediately reissue the command.

+.Sh NAME
+.Nm ispcvt
+.Nd verify if current video driver is pcvt driver
+.Sh SYNOPSIS
+.Nm
+.Op Fl c
+.Op Fl d Ar device
+.Op Fl n
+.Op Fl v
+.Sh DESCRIPTION
+The
+.Nm
+utility allows the user to check whether the current video driver compiled
+into the kernel is a pcvt driver.
+The major and minor release numbers of
+the driver are also checked.
+Furthermore
+.Nm
+is also able to print out the values of all the
+.Dq Ar PCVT_XXXXXX
+compile time options, the driver in the current running kernel was
+compiled with.
+.Pp
+The options are as follows:
+.Bl -tag -width Ds
+.It Fl d
+Specifies a device for which the check is done.
+.It Fl v
+Specifies being verbose.
+On success the name and revision is reported, on
+failure which comparison failed.
+.It Fl n
+print the number of compiled-in virtual terminals.
+.It Fl c
+This options prints out the values of all
+.Dq Ar PCVT_XXXXXX
+#defines which were given to the compiler at the time the currently running
+kernel was compiled.
+Specifying
+.Fl v
+with the
+.Fl c
+option gives a verbose listing of the compile-time options.
+.El
+.Sh DIAGNOSTICS
+The
+.Nm
+utility exits with one of the following values:
+.Pp
+.Bl -tag -width indent -compact
+.It 0
+driver is pcvt and major and minor numbers match
+.It 1
+.Xr open 2
+or
+.Xr ioctl 2
+system call failed
+.It 2
+driver name mismatch
+.It 3
+name matched, release major number mismatch
+.It 4
+name and major number matched, release minor number mismatch
+.It 5
+usage error
+.El
+.Sh SEE ALSO
+.Xr pcvt 4

+.Sh NAME
+.Nm kcon
+.Nd pcvt keyboard control and remapping
+.Sh SYNOPSIS
+.Nm
+.Op Fl d Ar delay
+.Op Fl l
+.Op Fl m Ar map
+.Op Fl o
+.Op Fl p
+.Op Fl R
+.Op Fl r Ar rate
+.Op Fl s
+.Op Fl t Ns Ar +/-
+.Op Fl x
+.Sh DESCRIPTION
+The
+.Nm
+utility
+is used for controlling all aspects of keyboard configuration for the 'pcvt'
+video driver.
+.Pp
+The available options are:
+.Bl -tag -width flag
+.It Fl d Ar delay
+Specifies the delay after which the last key entered will be repeated by the
+Keyboard.
+Valid values are 0..3 corresponding to delays of 250, 500, 750 and
+1000 milliseconds.
+.It Fl l
+Displays the current keyboard map in use by the driver.
+.It Fl m Ar map
+Specifies the map entry to be searched in the keyboard capabilities database
+.Nm keycap .
+The database is searched for the entry and if found, the mapping
+is loaded and is used in the driver from then on.
+.It Fl o
+Switches display of control codes to octal in the listing of the current map.
+To be used in conjunction with the
+.Fl l
+option.
+.It Fl p
+Uses 'pure' output when listing - the Escape character is displayed in either
+octal or hexadecimal and not as 'ESC'. To be used in conjunction with the
+.Fl l
+option.
+.It Fl r Ar rate
+Specifies the character repetition rate.
+Valid argument values are 0...31
+corresponding to rates of 30 characters/second ... 2 characters/second.
+.It Fl R
+Reset the Keyboard.
+.It Fl s
+Displays the current settings of the rate and delay values.
+.It Fl t Ar +/-
+Specify this option to enable
+.Pq Ar +
+or disable
+.Pq Ar -
+the repetition of keys.
+.It Fl x
+Switches display of control codes to hexadecimal in the listing of the current map.
+To be used in conjunction with the
+.Fl l
+option.
+This is the default behaviour.
+.El
+.Sh FILES
+.Bl -tag -width /usr/share/misc/keycap.pcvt -compact
+.It Pa /usr/share/misc/keycap.pcvt
+Keyboard capabilities data base file if nothing else was chosen during installation.
+.It Pa /dev/console
+Keyboard raw device.
+.El
+.Sh SEE ALSO
+.Xr keycap 3 ,
+.Xr keycap 5
+.Sh BUGS
+The
+.Nm
+utility detects several inconsistencies in the keycap database.
+In case of errors
+.Nm
+exits with an error message.
+If this happens, the keyboard may remain in
+an undefined state.
+To recover from such situation, execute
+.Dq Li kcon -m default .
+.Sh EXAMPLES
+The command
+.Dq Li kcon -m gb
+loads the entry 'gb' from the keycap file into the keyboard to switch to
+a british keyboard behaviour.
+.Pp
+The command
+.Dq Li kcon -r 0 -d 0
+switches the keyboard to emit characters at a rate of 30 characters per second
+after a key has been held down for 250 milliseconds.

+.Fn kgetent "char *bp" "char *name"
+.Ft int
+.Fn kgetnum "char *id"
+.Ft int
+.Fn kgetflag "char *id"
+.Ft char *
+.Fn kgetstr "char *id" "char **area"
+.Sh DESCRIPTION
+These functions extract and use capabilities from a keyboard capability data
+base, usually
+.Pa /usr/share/misc/keycap.pcvt ,
+the format of which is described in
+.Xr keycap 5 .
+.Pp
+The
+.Fn kgetent
+function
+extracts the entry for keyboard mapping
+.Fa name
+into the buffer at
+.Fa bp .
+The
+.Fa bp
+argument
+should be a character buffer of size
+1024 and must be retained through all subsequent calls to
+.Fn kgetnum ,
+.Fn kgetflag ,
+and
+.Fn kgetstr .
+The
+.Fn kgetent
+function
+returns \-1 if none of the
+.Nm keycap
+data base files could be opened,
+0 if the map name given does not have an entry,
+and 1 if all goes well.
+.Pp
+The
+.Fn kgetnum
+function
+gets the numeric value of capability
+.Fa id ,
+returning \-1 if is not given for the map.
+.Pp
+The
+.Fn kgetflag
+function
+returns 1 if the specified capability is present in
+the map's entry, 0 if it is not.
+.Pp
+The
+.Fn kgetstr
+function
+returns the string value of the capability
+.Fa id ,
+places it in the buffer at
+.Fa area ,
+and advances the
+.Fa area
+pointer.
+The
+.Fn kgetstr
+function
+returns
+.Dv NULL
+if the capability was not found.

+.Sh DESCRIPTION
+The
+.Nm
+utility controls several aspects of the runtime behaviour of the pcvt vt220
+driver.
+.Pp
+The options are as follows:
+.Bl -tag -width Ds
+.It Fl a
+Returns a string describing the video adaptor found by pcvt, the string
+returned could be MDA, HGC, CGA, EGA, VGA or UNKNOWN.
+.It Fl c
+Specify the screen number the current (displayed) screen should be switched
+to.
+.It Fl d
+Specify the device filename (i.e. /dev/ttyv2) further operations specified on
+the command line should be applied to.
+.It Fl f
+Some programs which silently assume 24 lines when they run on a VT220 show
+incorrect behaviour when the terminal has really 25 lines.
+To support full
+VT220 behaviour, it is possible to force pcvt to select only 24 lines when
+it is running in 25-lines pure VT mode and/or in 28-lines HP-mode.
+The
+.Fl f
+option requires one additional parameter, the string 'on' or 'off' to switch
+this mode for a virtual screen on or off respectively.
+This mode has no effect
+if any other vertical resolutions are selected than the two above mentioned.
+.It Fl h
+Prints a usage/help text.
+.It Fl l
+Lists the current configuration of runtime changeable options and fixed
+parameters (such as the type of the adaptor, and in case of a VGA adaptor,
+the Manufacturer, Chipset and 132 column support) of the output portion
+of the pcvt driver.
+.It Fl m
+Returns a string describing the connected display monitor type found by pcvt,
+the string returned can be MONO, COLOR or UNKNOWN.
+.It Fl v
+Specify verbose operation of the program.
+.It Fl V
+Switch the specified/current screen into a pure VT220 mode without recognizing
+any HP escape sequences and without displaying function key labels.
+.It Fl H
+Switch the specified/current screen into a mixed HP/VT220 mode.
+That is, that
+in addition to the full VT220 emulation, the HP function key labels and the
+escape sequences for handling the labels are available to the user.
+.It Fl s
+Specify the number of character lines on the screen.
+Possible parameters are
+25, 28, 35, 40, 43 or 50. To use all this screen sizes, the fonts required
+for proper operation of a desired size have to be downloaded to the EGA/VGA
+font ram.
+This option is available only for EGA and VGA boards.
+.It Fl p
+Modify VGA palette
+(DAC).
+The
+.Fl p
+is mutually exclusive with
+.Fl s ,
+.Fl H ,
+and
+.Fl V .
+Naturally, option
+.Fl p
+is available only for VGA boards.
+Three flavors are available.
+.Pp
+If used with argument
+.Dq Ar default ,
+this flag will restore the default palette
+(as installed by VGA ROM BIOS after hardware reset).
+.Pp
+If used with argument
+.Dq Ar list ,
+the current VGA DAC palette entries are listed.
+Each entry contains
+the table index, values for red, green, and blue, and if there's a
+known name for this entry, the color name.
+Trailing empty table
+slots (RGB values all zero) are omitted.
+.Pp
+Otherwise, four comma-separated arguments are expected.
+The first
+denotes the number of palette entry to be modified.
+This may be either
+a number between 0 and 255, or the usual name of an associated color
+(case-insensitive).
+The following values for red, green and blue are restricted to 0 through 63
+due to VGA DAC conventions.
+Note that the first delimiter within such an argument may be a colon
+.Dq \&:
+instead of a comma
+.Dq \&,
+for better readability, but this violates common command argument
+conventions.
+Multiple
+.Fl p
+options may be specified if unambiguous.
+.It Fl t
+Specifying
+.Fl t
+will activate the screen saver.
+The behaviour depends on
+.Ar timeout :
+if
+.Ar timeout
+is given as 0, the screen saver is turned off.
+Otherwise,
+.Ar timeout
+is taken as a number of seconds to wait until activating the
+screen saver.
+NOTE: the
+.Fl t
+option is only available if screen saver support has been compiled into
+the driver!
+.It Fl 1
+Sets 132 columns mode
+(only available on VGA adaptors).
+.It Fl 8
+Sets 80 columns mode.
+.El
+.Pp
+When switching between HP and VT mode, when switching the force 24 lines
+mode on and off, or when switching between 80 and 132 columns operation,
+the screen is cleared, the scrolling
+region is reset and the cursor is placed in the home position.
+.Sh EXAMPLES
+The command
+.Dq Li scon Fl H s Ar 28
+places the current screen into HP mode and sets the screen size to 28x80.
+.Pp
+Invoking
+.Do
+.Li scon Fl p
+.Ar lightgray,0,15,0
+.Fl p
+.Ar 0:45,45,45
+.Dc
+will result in green on gray output for normal text.
+Note that normal text color is light gray, and not white as one might expect.
+.Sh BUGS
+the
+.Fl c
+and
+.Fl d
+options collide somehow, this will change in a future release.

+.Sh NAME
+.Nm vt220keys
+.Nd "define SHIFTED function keys on VT220 terminal"
+.Sh SYNOPSIS
+.Nm
+.Op Fl cil
+.Op Ar keyname keystring ...
+.Sh DESCRIPTION
+The
+.Nm
+utility sets up a
+.Dq "vt220 terminal"
+in vt200 mode to allow user
+definition of the SHIFTED function keys.
+Each
+.Ar keyname
+specified on the command line will be loaded with
+the corresponding
+.Ar keystring .
+A
+.Ar keyname
+is one of the following words:
+.Cm F6 F7 F8 F9 F10 F11 ESC
+.Cm F12 BS F13 LF F14 HELP
+.Cm DO F17 F18 F19 F20 .
+.Ar Keystrings
+must be quoted if spaces, tabs, or shell metacharacters are included.
+.Pp
+The
+.Nm
+utility expects to receive some combination of option flags and/or
+argument pair(s), otherwise a usage message
+is printed.
+.Pp
+The options are:
+.Bl -tag -width indent
+.It Fl c
+Clears all SHIFTED function key definitions before setting them to user
+defined strings.
+.It Fl i
+Read the initialization file
+.Pa $HOME/.vt220rc
+for SHIFTED function key definitions.
+This is done before any
+argument pair specified on the command line is processed.
+Each line in the file must consist of two fields (separated by spaces
+or tabs) where the first field is the
+.Ar keyname
+and the second field is the
+.Ar keystring .
+The second field extends to the end of the line, thus a
+.Ar keystring
+may include spaces or tabs.
+A newline (return) may be specified
+within the string by using the C Language notation for newline (\\n).
+.It Fl l
+Locks the function keys from further definition.
+Locking occurs after processing the initialization file (if the
+.Fl i
+option is specified) and any argument
+pairs.
+The only way
+to unlock is by turning the power off.
+.El
+.Sh EXAMPLES
+.Bd -literal
+vt220keys -ci
+vt220keys F6 'nroff -ms '
+vt220keys -i F20 'cc -O -c '
+vt220keys -l HELP man
+.Ed
+.Sh "OTHER FEATURES"
+Pressing the function keys without using the shift key, generates
+a string of characters.
+With
+.Xr csh 1
+this string can be aliased to some command.
+For example:
+.Pp
+.Dl alias\ ^[[17~\ "ls\ -CR\ |\ more"
+.Pp
+where
+.Ql "^[[17~"
+is what is generated by pressing the F6 key.
+Therefore
+F6 can perform two commands, depending if pressed with/without the SHIFT
+key.
+.Pp
+The
+.Nm
+utility can be called from your
+.Pa .login
+or
+.Pa .profile
+file.
+Typically an user
+will create a initialization file and include a line like
+.Pp
+.Dl "vt220keys -ci"
+OR
+.Dl "vt220keys -cil"
+.Pp
+in the above mentioned files.
+This way the SHIFTED function keys
+will be set to your favorite commands when logging in.
+.Sh CAVEATS
+If the SHIFTED function keys are unlocked, redefinition of a SHIFTED
+function key will rewrite the old string.
+.Pp
+There are 256 bytes available for the SHIFTED function keys.
+Space is
+supplied on a first\-come/first\-serve basis.
+After the 256 bytes are
+used, you can't define any more keys unless space is cleared.
+This
+can be done by redefining a key to contain a string of fewer bytes.
+.Pp
+All key definitions are stored in volatile RAM, and are lost when
+terminal power is lost.
+.Pp
+The ESC key (unshifted) no longer generates the proper escape character.
+This
+is of particular importance since many editors require use of the
+ESC key.
+Here are some available alternatives:
+.Bl -bullet
+.It
+The escape character can be generated by typing
+.Ql ^[
+(control\-[).
+.It
+Use
+.Nm
+as follows (note
+.Ql ^[
+is control\-[)
+.Pp
+.Dl "vt220keys ESC '^['"
+.Pp
+This will require you
+to press the SHIFT key and ESC to generate the escape sequence.
+.It
+Some editors, allow other character(s) to be substituted for the
+escape character.
+For example with
+.Xr emacs 1
+include this line in your
+.Pa .emacs_pro :
+.Pp
+.Dl (bind-to-key\ "ESC-prefix"\ "\\033[23~")
+.Pp
+Thus when the ESC key is pressed,
+.Nm emacs
+will allow the characters generated
+.Pq Li ^[[23~
+to perform the same function as the escape
+character.

+        should make it easier to used this program.  Also added code
+        that will set-up the terminal in vt200 (this saves the user the
+        trouble of checking if the set-up is in vt200).
+
+        Restructed  the  main  function  to  use   getopt,  for  argument
+        processing.
+
+        Alterated usage function  to include  new "i"  option (init file)

+.Sh NAME
+.Nm vgaio
+.Nd perform input/output on a Video Graphics Array
+.Sh SYNOPSIS
+.Nm
+.Op Fl d
+.Sh DESCRIPTION
+.Ss Purpose
+.Nm Vgaio
+is used to perform register-level input/output on a Video Graphics Array.
+Since some of the sequences required to access those registers are very
+silly,
+.Nm
+cares of all the things necessary and allows the user to access the
+registers of several register groups with their symbolic names.
+.Ss Options
+.Bl -tag -width 10n -offset indent
+.It Fl d
+Turn on the grammar parser debugger.
+.El
+.Ss Command language
+The command language of
+.Nm
+constitutes of some very simple tokens and rules.
+Commands are executed
+line by line as they are entered.
+Each line may contain any number of
+semicolon-separated input/output commands.
+.Pp
+Symbolic register names look like:
+.Pp
+.D1 Ao Em reggroup Ac Ns Aq Em regnumber
+.Pp
+with
+.Aq Em regnumber
+being any hexadecimal number
+(without a leading
+.Em 0x ) ,
+and
+.Aq Em reggroup
+one of the strings
+.Dq Em ar ,
+.Dq Em cr ,
+.Dq Em gr ,
+.Dq Em mi ,
+or
+.Dq Em sr ,
+standing for the
+.Em Attribute controller ,
+.Em CRT controller ,
+.Em Graphics controller ,
+.Em Miscellaneous Output Register ,
+or
+.Em Timing sequencer ,
+respectively.
+.Pp
+An input instruction has the form
+.Pp
+.D1 Ao Em regname Ac \&?
+.Pp
+and will cause
+.Nm
+to output a line like
+.Bd -ragged -offset indent
+.Aq Em regname
+.No = 0x Ns Aq Em number
+.Ed
+.Pp
+An output instruction looks like
+.Bd -ragged -offset indent
+.Ao Em regname Ac =
+.Aq Em number
+.Ed
+.Pp
+Spaces or Tabs between the
+.Aq Em reggroup ,
+the
+.Aq Em regnumber ,
+or any of the other tokens are ignored.
+They are not required anyway.
+.Pp
+The
+.Dq Em mi
+needs a single unused argument to satisfy the syntax :-) (-hm).
+.Ss Access control
+The caller must have uid 0 in order to gain the required access to
+the IO registers.
+.Sh HISTORY
+This program is considered
+.Dq hackware .
+It has been developed in order to simplify the process of developing other
+software that needs to program the Video Graphics Array.
+.Pp
+Remember, to use this program, your kernel has to be compiled with XSERVER
+being defined!
+.Sh AUTHORS
+The program has been contributed by
+.An J\(:org Wunsch ,
+Dresden
+.Aq joerg_wunsch@uriah.sax.de .

+NOTES FROM THE MOD.SOURCES MODERATOR:
+I split the source up into the three separate pieces it now is.
+In doing this, I put lines like "int reading;" in a header file
+that both C modules include.  If your Unix requires one of these
+to be "extern int reading;" then you will have some editing to do.
+Also note that this program uses FIONREAD, which must be implemented
+differently in SystemV, etc., and check out the setjmp() call...
+	/Rich $alz
+Oh, yeah:  I also wrote the Makefile and manpage, such as they are.
+-------------------------------------------------------------------
+
+This is a program to test the compatibility (or to demonstrate the
+non-compatibility) of so-called "VT100-compatible" terminals. In
+conformance of the good old hacker traditions, the only documentation
+of this program is the source code itself. To understand it, you also
+need a copy of the original VT100 manual from DEC.
+
+Comments and bug reports: Since this is a release (via USENET) to the
+whole world, a lot of people are going to have opinions and fresh
+ideas about it. (What -- bugs in MY program? Aww...)  I can't deal
+with everyone sending me a hacked version, but if you have found a
+serious bug, or ported it to VMS, do tell me. I can't promise any new
+version release, though. From this version on (1.7b) VTTEST will have
+to live its own life without its father holding its hand.
+
+My address is:
+
+Network-mail address:     (mcvax,seismo)!enea!suadb!lindberg
+
+Real-world-mail address: Per Lindberg
+                         QZ, Stockholm University Computing Center
+			 Box 27322
+			 S - 102 54  Stockholm
+			 SWEDEN
+
+The original version of this program is written for the Sargasso C
+compiler for the DECsystem-10. Many thanks to all sales persons with
+quote VT100-compatible unquote terminals, who prompted me to write
+this program, and also to:
+
+-- Bo Kleve, LIDAC, Linkoping University, Sweden
+   for the portation to DECSYSTEM-20 with the Sargasso C compiler
+
+-- Johan Widen, TTDS, Royal Institute of Technology, Stockholm, Sweden
+   for the portation to various UNIX systems (incl. System III and Xenix)
+
+-- Russ Herman, AES Data Inc., Missisauga, Ont. Canada
+   for fixes and code for the VT102 test
+
+Thanx also to JMR "Gremlin" at KTH, and Goran Wallberg at QZ
+for suggestions, bug fixes, etc.
+
+This program does not have support for all the different variations
+of VT100, like VT125, VT131 nor the new VT200 series. Feel free to
+add that yourself. Happy Hacking!

+.Sh NAME
+.Nm periodic
+.Nd run periodic system functions
+.Sh SYNOPSIS
+.Nm
+.Ar directory ...
+.Sh DESCRIPTION
+The
+.Nm
+program is intended to be called by
+.Xr cron 8
+to execute shell scripts
+located in the specified directory.
+.Pp
+One or more of the following arguments must be specified:
+.Bl -tag -width ".Pa monthly"
+.It Pa daily
+Perform the standard daily periodic executable run.
+This usually occurs early in the morning (local time).
+.It Pa weekly
+Perform the standard weekly periodic executable run.
+This usually occurs on Sunday mornings.
+.It Pa monthly
+Perform the standard monthly periodic executable run.
+This usually occurs on the first day of the month.
+.It Pa security
+Perform the standard daily security checks.
+This is usually spawned by the
+.Pa daily
+run.
+.It Ar path
+An arbitrary directory containing a set of executables to be run.
+.El
+.Pp
+If an argument is an absolute directory name it is used as is, otherwise
+it is searched for under
+.Pa /etc/periodic
+and any other directories specified by the
+.Va local_periodic
+setting in
+.Xr periodic.conf 5
+(see below).
+.Pp
+The
+.Nm
+program will run each executable file in the directory or directories
+specified.
+If a file does not have the executable bit set, it is silently ignored.
+.Pp
+Each script is required to exit with one of the following values:
+.Bl -tag -width 4n
+.It 0
+The script has produced nothing notable in its output.
+The
+.Ao Ar basedir Ac Ns Va _show_success
+variable controls the masking of this output.
+.It 1
+The script has produced some notable information in its output.
+The
+.Ao Ar basedir Ac Ns Va _show_info
+variable controls the masking of this output.
+.It 2
+The script has produced some warnings due to invalid configuration settings.
+The
+.Ao Ar basedir Ac Ns Va _show_badconfig
+variable controls the masking of this output.
+.It >2
+The script has produced output that must not be masked.
+.El
+.Pp
+If the relevant variable (where
+.Aq Ar basedir
+is the base directory in which the script resides) is set to
+.Dq Li NO
+in
+.Pa periodic.conf ,
+.Nm
+will mask the script output.
+If the variable is not set to either
+.Dq Li YES
+or
+.Dq Li NO ,
+it will be given a default value as described in
+.Xr periodic.conf 5 .
+.Pp
+All remaining script output is delivered based on the value of the
+.Ao Ar basedir Ac Ns Va _output
+setting.
+.Pp
+If this is set to a path name (beginning with a
+.Ql /
+character), output is simply logged to that file.
+.Xr newsyslog 8
+knows about the files
+.Pa /var/log/daily.log , /var/log/weekly.log
+and
+.Pa /var/log/monthly.log ,
+and if they exist, it will rotate them at the appropriate times.
+These are therefore good values if you wish to log
+.Nm
+output.
+.Pp
+If the
+.Ao Ar basedir Ac Ns Va _output
+value does not begin with a
+.Ql /
+and is not empty, it is assumed to contain a list of email addresses, and
+the output is mailed to them.
+.Pp
+If
+.Ao Ar basedir Ac Ns Va _output
+is not set or is empty, output is sent to standard output.
+.Sh ENVIRONMENT
+The
+.Nm
+command sets the
+.Ev PATH
+environment to include all standard system directories, but no additional
+directories, such as
+.Pa /usr/local/bin .
+If executables are added which depend upon other path components, each
+executable must be responsible for configuring its own appropriate environment.
+.Sh FILES
+.Bl -tag -width ".Pa /etc/periodic.conf"
+.It Pa /etc/crontab
+The
+.Nm
+program is typically called via entries in the system default
+.Xr cron 8
+table.
+.It Pa /etc/periodic
+The top level directory containing
+.Pa daily ,
+.Pa weekly ,
+and
+.Pa monthly
+subdirectories which contain standard system periodic executables.
+.It Pa /etc/defaults/periodic.conf
+The
+.Pa periodic.conf
+system registry contains variables that control the behaviour of
+.Nm
+and the standard
+.Pa daily , weekly ,
+and
+.Pa monthly
+scripts.
+.It Pa /etc/periodic.conf
+This file contains local overrides for the default
+.Nm
+configuration.
+.El
+.Sh EXAMPLES
+The system crontab should have entries for
+.Nm
+similar to the following example:
+.Bd -literal -offset indent
+# do daily/weekly/monthly maintenance
+0      2       *       *       *       root    periodic daily
+0      3       *       *       6       root    periodic weekly
+0      5       1       *       *       root    periodic monthly
+.Ed
+.Pp
+The
+.Pa /etc/defaults/periodic.conf
+system registry will typically have a
+.Va local_periodic
+variable reading:
+.Pp
+.Dl local_periodic="/usr/local/etc/periodic /usr/X11R6/etc/periodic"
+.Pp
+To log
+.Nm
+output instead of receiving it as email, add the following lines to
+.Pa /etc/periodic.conf :
+.Bd -literal -offset indent
+daily_output=/var/log/daily.log
+weekly_output=/var/log/weekly.log
+monthly_output=/var/log/monthly.log
+.Ed
+.Pp
+To only see important information from daily periodic jobs, add the
+following lines to
+.Pa /etc/periodic.conf :
+.Bd -literal -offset indent
+daily_show_success=NO
+daily_show_info=NO
+daily_show_badconfig=NO
+.Ed
+.Sh SEE ALSO
+.Xr sh 1 ,
+.Xr crontab 5 ,
+.Xr periodic.conf 5 ,
+.Xr cron 8 ,
+.Xr newsyslog 8
+.Sh DIAGNOSTICS
+Exit status is 0 on success and 1 if the command
+fails for one of the following reasons:
+.Bl -diag
+.It usage: periodic <directory of files to execute>
+No directory path argument was passed to
+.Nm
+to specify where the script fragments reside.
+.It <directory> not found
+Self explanatory.
+.El
+.Sh HISTORY
+The
+.Nm
+program first appeared in
+.Fx 3.0 .
+.Sh BUGS
+Since one specifies information about a directory using shell
+variables containing the string,
+.Aq Ar basedir ,
+.Aq Ar basedir
+must only contain characters that are valid within a
+.Xr sh 1
+variable name, alphanumerics and underscores, and the first character
+may not be numeric.

+.Dt PKG_ADD 1
+.Os
+.Sh NAME
+.Nm pkg_add
+.Nd a utility for installing software package distributions
+.Sh SYNOPSIS
+.Nm
+.Op Fl vInfrRMS
+.Op Fl t Ar template
+.Op Fl p Ar prefix
+.Ar pkg-name Op Ar pkg-name ...
+.Sh DESCRIPTION
+The
+.Nm
+command is used to extract packages that have been previously created
+with the
+.Xr pkg_create 1
+command.
+.Sh WARNING
+.Bf -emphasis
+Since the
+.Nm
+command may execute scripts or programs contained within a package file,
+your system may be susceptible to
+.Dq Em trojan horses
+or other subtle
+attacks from miscreants who create dangerous package files.
+.Pp
+You are advised to verify the competence and identity of those who
+provide installable package files.  For extra protection, use the
+.Fl M
+flag to extract the package file, and inspect its contents and scripts to
+ensure it poses no danger to your system's integrity.  Pay particular
+attention to any +INSTALL, +POST-INSTALL, +DEINSTALL, +POST-DEINSTALL,
++REQUIRE or +MTREE_DIRS files, and inspect the +CONTENTS file for
+.Cm @cwd ,
+.Cm @mode
+(check for setuid),
+.Cm @dirrm ,
+.Cm @exec ,
+and
+.Cm @unexec
+directives, and/or use the
+.Xr pkg_info 1
+command to examine the package file.
+.Ef
+.Sh OPTIONS
+The following command line arguments are supported:
+.Bl -tag -width indent
+.It Ar pkg-name Op Ar pkg-name ...
+The named packages are installed.  A package name of - will cause
+.Nm
+to read from stdin.
+If the packages are not found in the current
+working directory,
+.Nm
+will search them in each directory named by
+.Ev PKG_PATH .
+.It Fl v
+Turn on verbose output.
+.It Fl I
+If a installation scripts (pre-install or post-install) exist for a given
+package, do not execute them.
+.It Fl n
+Don't actually install a package, just report the steps that
+would be taken if it was.
+.It Fl R
+Do not record the installation of a package.  This means
+that you cannot deinstall it later, so only use this option if
+you know what you are doing!
+.It Fl r
+Use the remote fetching feature.
+This will determine the appropriate
+objformat and release and then fetch and install the package.
+.It Fl f
+Force installation to proceed even if prerequisite packages are not
+installed or the requirements script fails.  Although
+.Nm
+will still try to find and auto-install missing prerequisite packages,
+a failure to find one will not be fatal.
+.It Fl p Ar prefix
+Set
+.Ar prefix
+as the directory in which to extract files from a package.
+If a package has set its default directory, it will be overridden
+by this flag.  Note that only the first
+.Cm @cwd
+directive will be replaced, since
+.Nm
+has no way of knowing which directory settings are relative and
+which are absolute.  It is rare in any case to see more than one
+directory transition made, but when such does happen and you wish
+to have control over *all* directory transitions, then you
+may then wish to look into the use of
+.Cm MASTER
+and
+.Cm SLAVE
+modes (see the
+.Fl M
+and
+.Fl S
+options).
+.It Fl t Ar template
+Use
+.Ar template
+as the input to
+.Xr mktemp 3
+when creating a
+.Dq staging area .
+By default, this is the string
+.Pa /var/tmp/instmp.XXXXXX ,
+but it may be necessary to override it in the situation where
+space in your
+.Pa /var/tmp
+directory is limited.  Be sure to leave some number of `X' characters
+for
+.Xr mktemp 3
+to fill in with a unique ID.
+.Pp
+You can get a performance boost by setting the staging area
+.Ar template
+to reside on the same disk partition as target directories for package
+file installation; often this is
+.Pa /usr .
+.It Fl M
+Run in
+.Cm MASTER
+mode.  This is a very specialized mode for running
+.Nm
+and is meant to be run in conjunction with
+.Cm SLAVE
+mode.  When run in this mode,
+.Nm
+does no work beyond extracting the package into a temporary staging
+area (see the
+.Fl t
+option), reading in the packing list, and then dumping it (prefaced by
+the current staging area) to stdout where it may be filtered by a
+program such as
+.Xr sed 1 .
+When used in conjunction with
+.Cm SLAVE
+mode, it allows you to make radical changes to the package structure
+before acting on its contents.
+.It Fl S
+Run in
+.Cm SLAVE
+mode.  This is a very specialized mode for running
+.Nm
+and is meant to be run in conjunction with
+.Cm MASTER
+mode.  When run in this mode,
+.Nm
+expects the release contents to be already extracted and waiting
+in the staging area, the location of which is read as a string
+from stdin.  The complete packing list is also read from stdin,
+and the contents then acted on as normal.
+.El
+.Pp
+One or more
+.Ar pkg-name
+arguments may be specified, each being either a file containing the
+package (these usually ending with the
+.Dq .tgz
+suffix) or a
+URL pointing at a file available on an ftp site.  Thus you may
+extract files directly from their anonymous ftp locations (e.g.\&
+.Nm
+.Li ftp://ftp.FreeBSD.org/pub/FreeBSD/packages/shells/bash-1.14.4.tgz ) .
+Note:  If you wish to use
+.Bf -emphasis
+passive mode
+.Ef
+ftp in such transfers, set
+the variable
+.Bf -emphasis
+FTP_PASSIVE_MODE
+.Ef
+to some value in your environment.  Otherwise, the more standard
+ACTIVE mode may be used.  If
+.Nm
+consistently fails to fetch a package from a site known to work,
+it may be because you have a firewall that demands the usage of
+.Bf -emphasis
+passive mode
+.Ef
+ftp.
+.Sh TECHNICAL DETAILS
+The
+.Nm
+utility is fairly simple.  It extracts each package's "packing list"
+into a special staging directory, parses it,
+and then runs through the following sequence to fully extract the contents:
+.Bl -enum
+.It
+Check if the package is already recorded as installed.  If so,
+terminate installation.
+.It
+Scan all the package dependencies (from
+.Cm @pkgdep
+directives, see
+.Xr pkg_create 1 )
+and make sure each one is met.  If not, try and find the missing
+dependencies' packages and auto-install them; if they can't be found
+the installation is terminated.
+.It
+Search for any
+.Cm @option
+directives which control how the package is added to the system.
+At the time of this writing, the only currently implemented option is
+.Cm @option extract-in-place
+which will cause the package to be extracted directly into its
+prefix directory without moving through a staging area in
+.Pa /tmp .
+.It
+If
+.Cm @option extract-in-place
+is enabled, the package is now extracted directly into its
+final location, otherwise it is extracted into the staging area.
+.It
+If the package contains a
+.Ar require
+file (see
+.Xr pkg_create 1 ) ,
+then execute it with the following arguments:
+.Bd -ragged -offset indent -compact
+.Ar pkg-name
+.Ar INSTALL
+.Ed
+where
+.Ar pkg-name
+is the name of the package in question and the
+.Ar INSTALL
+keyword denotes this as an installation requirements check (useful if
+you want to have one script serving multiple functions).
+.It
+If a
+.Ar pre-install
+script exists for the package, it is then executed with the following
+arguments:
+.Bd -ragged -offset indent -compact
+.Cm script
+.Ar pkg-name
+.Ar PRE-INSTALL
+.Ed
+.Pp
+where
+.Ar pkg-name
+is the name of the package in question and
+.Ar PRE-INSTALL
+is a keyword denoting this as the preinstallation phase.
+.Pp
+.Sy Note :
+The
+.Ar PRE-INSTALL
+keyword will not appear if separate scripts for pre-install and post-install
+are given during package creation time (using the
+.Fl i
+and
+.Fl I
+flags to
+.Xr pkg_create 1 ) .
+.It
+If
+.Cm @option extract-in-place
+is not used, then the packing list (this is the
+.Pa +CONTENTS
+file) is now used as a guide for moving (or copying, as necessary) files from
+the staging area into their final locations.
+.It
+If the package contains an
+.Ar mtreefile
+file (see
+.Xr pkg_create 1 ) ,
+then mtree is invoked as:
+.Bd -ragged -offset indent -compact
+.Cm mtree
+.Fl u
+.Fl f
+.Ar mtreefile
+.Fl d
+.Fl e
+.Fl p
+.Pa prefix
+.Ed
+where
+.Pa prefix
+is either the prefix specified with the
+.Fl p
+flag or, if no
+.Fl p
+flag was specified, the name of the first directory named by a
+.Cm @cwd
+directive within this package.
+.It
+If a
+.Ar post-install
+script exists for the package, it is then executed as
+.Bd -ragged -offset indent -compact
+.Cm script
+.Ar pkg-name
+.Ar POST-INSTALL
+.Ed
+where
+.Ar pkg-name
+is the name of the package in question and
+.Ar POST-INSTALL
+is a keyword denoting this as the post-installation phase.
+.Pp
+.Sy Note :
+The
+.Ar POST-INSTALL
+keyword will not appear if separate scripts for pre-install and post-install
+are given during package creation time (using the
+.Fl i
+and
+.Fl I
+flags to
+.Xr pkg_create 1 ) .
+.Pp
+Reasoning behind passing keywords such as
+.Ar POST-INSTALL
+and
+.Ar PRE-INSTALL
+is that this allows you to write a single
+.Ar install
+script that does both
+.Dq before and after
+actions.
+But, separating the
+functionality is more advantageous and easier from a maintainence viewpoint.
+.It
+After installation is complete, a copy of the packing list,
+.Ar deinstall
+script, description, and display files are copied into
+.Pa /var/db/pkg/<pkg-name>
+for subsequent possible use by
+.Xr pkg_delete 1 .
+Any package dependencies are recorded in the other packages'
+.Pa /var/db/pkg/<other-pkg>/+REQUIRED_BY
+file
+(if the environment variable PKG_DBDIR is set, this overrides the
+.Pa /var/db/pkg/
+path shown above).
+.It
+Finally, the staging area is deleted and the program terminates.
+.El
+.Pp
+All the scripts are called with the environment variable
+.Ev PKG_PREFIX
+set to the installation prefix (see the
+.Fl p
+option above).  This allows a package author to write a script
+that reliably performs some action on the directory where the package
+is installed, even if the user might change it with the
+.Fl p
+flag to
+.Cm pkg_add .
+.Sh ENVIRONMENT
+The value of the
+.Ev PKG_PATH
+is used if a given package can't be found.  The environment variable
+should be a series of entries separated by colons.  Each entry
+consists of a directory name.
+The current directory may be indicated
+implicitly by an empty directory name, or explicitly by a single
+period.
+.Pp
+The environment variable
+.Ev PKG_DBDIR
+specifies an alternative location for the installed package database.
+.Pp
+The environment variables
+.Ev PKG_TMPDIR
+and
+.Ev TMPDIR ,
+in that order, are taken to name temporary directories where
+.Nm
+will attempt to create its staging area in.
+If these variables are not present or if the directories named lack
+sufficient space, then
+.Nm
+will use the first of
+.Pa /var/tmp ,
+.Pa /tmp
+or
+.Pa /usr/tmp
+with sufficient space.
+.Pp
+The environment variable
+.Ev PACKAGEROOT
+specifies an alternate location for
+.Nm
+to fetch from.
+The fetch URL is built using this environment variable and the automatic
+directory logic that
+.Nm
+uses when the
+.Fl r
+option is invoked.
+An example setting would be
+.Qq Li ftp://ftp3.FreeBSD.org .
+.Pp
+The environment variable
+.Ev PACKAGESITE
+specifies an alternate location for
+.Nm
+to fetch from.
+This variable subverts the automatic directory logic
+that
+.Nm
+uses when the
+.Fl r
+option is invoked.
+Thus it should be a complete URL to the remote package file(s).
+.Sh FILES
+.Bl -tag -width /var/db/pkg -compact
+.It Pa /var/tmp
+Temporary directory for creating the staging area, if environmental variables
+.Ev PKG_TMPDIR
+or
+.Ev TMPDIR
+do not point to a suitable directory.
+.It Pa /tmp
+Next choice if
+.Pa /var/tmp
+does not exist or has insufficient space.
+.It Pa /usr/tmp
+Last choice if
+.Pa /var/tmp
+and
+.Pa /tmp
+are not suitable for creating the staging area.
+.It Pa /var/db/pkg
+Default location of the installed package database.

+Hard links between files in a distribution are only preserved if either
+(1) the staging area is on the same filesystem as the target directory of
+all the links to the file, or (2) all the links to the file are bracketed by
+.Cm @cwd
+directives in the contents file,
+.Em and
+the link names are extracted with a single
+.Cm tar
+command (not split between
+invocations due to exec argument-space limitations--this depends on the
+value returned by
+.Fn sysconf _SC_ARG_MAX ) .

+Sure to be others.

+.Sh NAME
+.Nm pkg_create
+.Nd a utility for creating software package distributions
+.Sh SYNOPSIS
+.Nm
+.Op Fl YNOhjvyz
+.Op Fl P Ar pkgs
+.Op Fl p Ar prefix
+.Op Fl f Ar contents
+.Op Fl i Ar iscript
+.Op Fl I Ar piscript
+.Op Fl k Ar dscript
+.Op Fl K Ar pdscript
+.Op Fl r Ar rscript
+.Op Fl s Ar srcdir
+.Op Fl t Ar template
+.Op Fl X Ar excludefile

+.Fl c Ar comment
+.Fl d Ar description
+.Fl f Ar packlist
+.Ar pkg-filename
+.Nm
+.Op Fl YNhvy
+.Fl b Ar pkg-name
+.Op Ar pkg-filename
+.Sh DESCRIPTION
+The
+.Nm
+command is used to create packages that will subsequently be fed to
+one of the package extraction/info utilities.  The input description
+and command line arguments for the creation of a package are not
+really meant to be human-generated, though it is easy enough to
+do so.  It is more expected that you will use a front-end tool for
+the job rather than muddling through it yourself.  Nonetheless, a short
+description of the input syntax is included in this document.
+.Sh OPTIONS
+The following command line options are supported:
+.Bl -tag -width indent
+.It Fl f Ar packinglist
+Fetch
+.Dq packing list
+for package from the file
+.Ar packinglist
+or
+.Cm stdin
+if
+.Ar packinglist
+is a
+.Cm -
+(dash).
+.It Fl c Xo
+.Oo Fl Oc Ns Ar desc
+.Xc
+Fetch package
+.Dq one line description
+from file
+.Ar desc
+or, if preceded by
+.Cm - ,
+the argument itself.  This string should also
+give some idea of which version of the product (if any) the package
+represents.
+.It Fl d Xo
+.Oo Fl Oc Ns Ar desc
+.Xc
+Fetch long description for package from file
+.Ar desc
+or, if preceded by
+.Cm - ,
+the argument itself.
+.It Fl Y
+Assume a default answer of `Yes' for any questions asked.
+.It Fl N
+Assume a default answer of `No' for any questions asked.
+.It Fl O
+Go into a `packing list Only' mode.  This is a custom hack for the
+.Fx
+.Em "Ports Collection"
+and is used to do `fake pkg_add' operations when a port is installed.
+In such cases, it is necessary to know what the final, adjusted packing
+list will look like.
+.It Fl v
+Turn on verbose output.
+.It Fl h
+Force tar to follow symbolic links, so that the files they point to
+are dumped, rather than the links themselves.
+.It Fl i Ar iscript
+Set
+.Ar iscript
+to be the pre-install procedure for the package.  This can be any executable
+program (or shell script).  It will be invoked automatically when the
+package is later installed.
+It will be passed the package's name as the
+first argument.
+.Pp
+.Sy Note :
+if the
+.Fl I
+option is not given, this script will serve as both the pre-install and the
+post-install script for the package, differentiating between the
+functionality by passing the keywords
+.Ar PRE-INSTALL
+and
+.Ar POST-INSTALL
+respectively, along with the package's name.
+.It Fl I Ar piscript
+Set
+.Ar piscript
+to be the post-install procedure for the package.  This can be any
+executable program (or shell script).  It will be invoked automatically
+when the package is later installed.
+It will be passed the package's name as
+the first argument.
+.It Fl P Ar pkgs
+Set the initial package dependency list to
+.Ar pkgs .
+This is assumed to be a whitespace separated list of package names
+and is meant as a convenient shorthand for specifying multiple
+.Cm @pkgdep
+directives in the packing list (see
+.Sx "PACKING LIST DETAILS"
+section below).
+Each argiment from the
+.Ar pkgs
+list could be in the form
+.Ar pkgname Ns Op : Ns Ar pkgorigin ,
+where optional
+.Ar pkgorigin
+element denotes origin of each dependency from the list and it is
+recorded into the packing list along with the
+.Ar pkgname
+using
+.Cm @comment
+directive.
+.It Fl p Ar prefix
+Set
+.Ar prefix
+as the initial directory
+.Dq base
+to start from in selecting files for
+the package.
+.It Fl k Ar dscript
+Set
+.Ar dscript
+to be the de-install procedure for the package.  This can be any executable
+program (or shell script).  It will be invoked automatically when the
+package is later (if ever) de-installed.
+It will be passed the package's
+name as the first argument.
+.Pp
+.Sy Note :
+if the
+.Fl K
+option is not given, this script will serve as both the de-install and the
+post-deinstall script for the package, differentiating between the
+functionality by passing the keywords
+.Ar DEINSTALL
+and
+.Ar POST-DEINSTALL
+respectively, along with the package's name.
+.It Fl K Ar pdscript
+Set
+.Ar pdscript
+to be the post-deinstall procedure for the package.  This can be any
+executable program (or shell script).  It will be invoked automatically when
+the package is later de-installed.
+It will be passed the package's name as
+the first argument.
+.It Fl r Ar rscript
+Set
+.Ar rscript
+to be the
+.Dq requirements
+procedure for the package.  This can be any
+executable program (or shell script).  It will be invoked automatically
+at installation/deinstallation time to determine whether or not
+installation/deinstallation should proceed.
+To differentiate between installation and deinstallation, the keywords
+.Ar INSTALL
+and
+.Ar DEINSTALL
+are passed respectively, along with the package's name.
+.It Fl s Ar srcdir
+.Ar srcdir
+will override the value of
+.Cm @cwd
+during package creation.
+.It Fl t Ar template
+Use
+.Ar template
+as the input to
+.Xr mktemp 3 .
+By default, this is the string
+.Pa /tmp/instmp.XXXXXX ,
+but it may be necessary to override it in the situation where
+space in your
+.Pa /tmp
+directory is limited.  Be sure to leave some number of `X' characters
+for
+.Xr mktemp 3
+to fill in with a unique ID.
+.It Fl X Ar excludefile
+Pass
+.Ar excludefile
+as a
+.Fl exclude-from
+argument to
+.Cm tar
+when creating final package.  See
+.Cm tar
+man page (or run
+.Cm tar
+with
+.Fl -help
+flag) for further information on using this flag.
+.It Fl D Ar displayfile
+Display the file (by concatenating it to stdout)
+after installing the package.  Useful for things like
+legal notices on almost-free software, etc.
+.It Fl m Ar mtreefile
+Run
+.Xr mtree 8
+with input from mtreefile before the package is installed.
+Mtree is invoked as
+.Cm mtree
+.Fl u
+.Fl f
+.Ar mtreefile
+.Fl d
+.Fl e
+.Fl p
+.Pa prefix ,
+where
+.Pa prefix
+is the name of the first directory named by a
+.Cm @cwd
+directive.
+.It Fl o Ar originpath
+Record an
+.Ar originpath ,
+as location of the port from which package has been created in the
+.Fx
+.Em "Ports Collection" .
+It should be in the form
+.Pa MASTERCATEGORY/PORTDIR .
+.It Fl j
+Use
+.Xr bzip2 1
+utility to compress package tarball instead of
+.Xr gzip 1 .
+Please note that this option is a NO-OP if the format of the resulting
+archive is explicitly specified by the recognizeable suffix of
+.Ar pkg-filename .
+Currently
+.Nm
+recognizes the following suffixes:
+.Pa .tgz , .tar , .tbz
+and
+.Pa .tbz2 .
+.It Fl y
+Compatibility synonym for
+.Fl j .
+.It Fl z
+Use
+.Xr gzip 1
+utility to compress package tarball.
+.It Fl b Ar pkg-name
+Create package file from a locally installed package named
+.Ar pkg-name .
+If the
+.Ar pkg-filename
+is not specified, then resulting archive will be created in the
+current directory and named
+.Ar pkg-name
+with an appropriate extraction suffix applied.
+.El
+.Sh PACKING LIST DETAILS
+The
+.Dq packing list
+format (see
+.Fl f )
+is fairly simple, being
+nothing more than a single column of filenames to include in the
+package.  However, since absolute pathnames are generally a bad idea
+for a package that could be installed potentially anywhere, there is
+another method of specifying where things are supposed to go
+and, optionally, what ownership and mode information they should be
+installed with.  This is done by imbeding specialized command sequences
+in the packing list.  Briefly described, these sequences are:
+.Bl -tag -width indent -compact
+.It Cm @cwd Ar directory
+Set the internal directory pointer to point to
+.Ar directory .
+All subsequent filenames will be assumed relative to this directory.
+Note:
+.Cm @cd
+is also an alias for this command.
+.It Cm @srcdir Ar directory
+Set the internal directory pointer for _creation only_ to
+.Ar directory .
+That is to say that it overrides
+.Cm @cwd
+for package creation but not extraction.
+.It Cm @exec Ar command
+Execute
+.Ar command
+as part of the unpacking process.  If
+.Ar command
+contains any of the following sequences somewhere in it, they will
+be expanded inline.  For the following examples, assume that
+.Cm @cwd
+is set to
+.Pa /usr/local
+and the last extracted file was
+.Pa bin/emacs .
+.Bl -tag -width indent -compact
+.It Cm "%F"
+Expands to the last filename extracted (as specified), in the example case
+.Pa bin/emacs
+.It Cm "\&%D"
+Expand to the current directory prefix, as set with
+.Cm @cwd ,
+in the example case
+.Pa /usr/local .
+.It Cm "\&%B"
+Expand to the
+.Dq basename
+of the fully qualified filename, that
+is the current directory prefix, plus the last filespec, minus
+the trailing filename.  In the example case, that would be
+.Pa /usr/local/bin .
+.It Cm "%f"
+Expand to the
+filename
+part of the fully qualified name, or
+the converse of
+.Cm \&%B ,
+being in the example case,
+.Pa emacs .
+.El
+.It Cm @unexec Ar command
+Execute
+.Ar command
+as part of the deinstallation process.  Expansion of special
+.Cm %
+sequences is the same as for
+.Cm @exec .
+This command is not executed during the package add, as
+.Cm @exec
+is, but rather when the package is deleted.  This is useful
+for deleting links and other ancillary files that were created
+as a result of adding the package, but not directly known to
+the package's table of contents (and hence not automatically
+removable).  The advantage of using
+.Cm @unexec
+over a deinstallation script is that you can use the
+.Dq special sequence expansion
+to get at files regardless of where they've
+been potentially redirected (see
+.Fl p ) .
+.It Cm @mode Ar mode
+Set default permission for all subsequently extracted files to
+.Ar mode .
+Format is the same as that used by the
+.Cm chmod
+command (well, considering that it's later handed off to it, that's
+no surprise).  Use without an arg to set back to default (extraction)
+permissions.
+.It Cm @option Ar option
+Set internal package options, the only two currently supported ones
+being
+.Ar extract-in-place ,
+which tells the pkg_add command not to extract the package's tarball
+into a staging area but rather directly into the target
+hierarchy (this is typically meant to be used only by distributions
+or other special package types), and
+.Ar preserve ,
+which tells pkg_add to move any existing files out of the way,
+preserving the previous contents (which are also resurrected on
+pkg_delete, so caveat emptor).
+.It Cm @owner Ar user
+Set default ownership for all subsequently extracted files to
+.Ar user .
+Use without an arg to set back to default (extraction)
+ownership.
+.It Cm @group Ar group
+Set default group ownership for all subsequently extracted files to
+.Ar group .
+Use without an arg to set back to default (extraction)
+group ownership.
+.It Cm @comment Ar string
+Imbed a comment in the packing list.  Useful in
+trying to document some particularly hairy sequence that
+may trip someone up later.
+.It Cm @ignore
+Used internally to tell extraction to ignore the next file (don't
+copy it anywhere), as it's used for some special purpose.
+.It Cm @ignore_inst
+Similar to
+.Cm @ignore ,
+but the ignoring of the next file is delayed one evaluation cycle.  This
+makes it possible to use this directive in the
+.Ar packinglist
+file, so you can pack a
+specialized datafile in with a distribution for your install script (or
+something) yet have the installer ignore it.
+.It Cm @name Ar name
+Set the name of the package.  This is mandatory and is usually
+put at the top.  This name is potentially different from the name of
+the file it came in, and is used when keeping track of the package
+for later deinstallation.  Note that
+.Nm
+will derive this field from the package name and add it automatically
+if none is given.
+.It Cm @dirrm Ar name
+Declare directory
+.Pa name
+to be deleted at deinstall time.  By default, directories created by a
+package installation are not deleted when the package is deinstalled;
+this provides an explicit directory cleanup method.  This directive
+should appear at the end of the package list.  If more than one
+.Cm @dirrm
+directives are used, the directories are removed in the order specified.
+The
+.Pa name
+directory will not be removed unless it is empty.
+.It Cm @mtree Ar name
+Declare
+.Pa name
+as an
+.Xr mtree 8
+input file to be used at install time (see
+.Fl m
+above).  Only the first
+.Cm @mtree
+directive is honored.
+.It Cm @display Ar name
+Declare
+.Pa name
+as the file to be displayed at install time (see
+.Fl D
+above).
+.It Cm @pkgdep Ar pkgname
+Declare a dependency on the
+.Ar pkgname
+package.  The
+.Ar pkgname
+package must be installed before this package may be
+installed, and this package must be deinstalled before the
+.Ar pkgname
+package is deinstalled.  Multiple
+.Cm @pkgdep
+directives may be used if the package depends on multiple other packages.
+.El
+.Sh ENVIRONMENT
+The environment variable
+.Ev PKG_TMPDIR
+names the directory where
+.Nm
+will attempt to create its temporary files.
+If
+.Ev PKG_TMPDIR
+is not set,
+the directory named by the contents of
+.Ev TMPDIR
+will be used.
+If neither of
+.Ev PKG_TMPDIR
+and
+.Ev TMPDIR
+are set, the builtin defaults are used.
+.Sh FILES
+.Bl -tag -width /usr/tmp -compact
+.It Pa /var/tmp
+Temporary directory if environmental variables
+.Ev PKG_TMPDIR
+and
+.Ev TMPDIR
+are not set.
+.It Pa /tmp
+The next choice if
+.Pa /var/tmp
+does not exist.
+.It Pa /usr/tmp
+The last choice if
+.Pa /tmp
+is unsuitable.

+.Sh BUGS
+Hard links between files in a distribution must be bracketed by
+.Cm @cwd
+directives in order to be preserved as hard links when the package is
+extracted.  They additionally must not end up being split between
+.Cm tar
+invocations due to exec argument-space limitations (this depends on the
+value returned by

+.Dt PKG_DELETE 1
+.Os
+.Sh NAME
+.Nm pkg_delete
+.Nd a utility for deleting previously installed software package distributions
+.Sh SYNOPSIS
+.Nm
+.Op Fl dDfGinrvx
+.Op Fl p Ar prefix
+.Ar pkg-name ...
+.Nm
+.Fl a
+.Op Ar flags
+.Sh DESCRIPTION
+The
+.Nm
+command is used to delete packages that have been previously installed
+with the
+.Xr pkg_add 1
+command.
+.Sh WARNING
+.Bf -emphasis
+Since the
+.Nm
+command may execute scripts or programs provided by a package file,
+your system may be susceptible to
+.Dq Em trojan horses
+or other subtle
+attacks from miscreants who create dangerous package files.
+.Pp
+You are advised to verify the competence and identity of those who
+provide installable package files.  For extra protection, examine all
+the package control files in the package record directory
+.Pa ( /var/db/pkg/<pkg-name>/ ) .
+Pay particular attention to any +INSTALL, +POST-INSTALL, +DEINSTALL,
++POST-DEINSTALL, +REQUIRE or +MTREE_DIRS files, and inspect the +CONTENTS
+file for
+.Cm @cwd ,
+.Cm @mode
+(check for setuid),
+.Cm @dirrm ,
+.Cm @exec ,
+and
+.Cm @unexec
+directives, and/or use the
+.Xr pkg_info 1
+command to examine the installed package control files.
+.Ef
+.Sh OPTIONS
+The following command line options are supported:
+.Bl -tag -width indent
+.It Ar pkg-name ...
+The named packages are deinstalled.
+.It Fl a
+Unconditionally delete all currently installed packages.
+.It Fl i
+Request confirmation before attempting to delete each package,
+regardless whether or not the standard input device is a
+terminal.
+.It Fl v
+Turn on verbose output.
+.It Fl D
+If a deinstallation script exists for a given package, do not execute it.
+.It Fl n
+Don't actually deinstall a package, just report the steps that
+would be taken if it were.
+.It Fl p Ar prefix
+Set
+.Ar prefix
+as the directory in which to delete files from any installed packages
+which do not explicitly set theirs.  For most packages, the prefix will
+be set automatically to the installed location by
+.Xr pkg_add 1 .
+.It Fl d
+Remove empty directories created by file cleanup.  By default, only
+files/directories explicitly listed in a package's contents (either as
+normal files/directories or with the
+.Cm @dirrm
+directive) will be removed at deinstallation time.  This option tells
+.Nm
+to also remove any directories that were emptied as a result of removing
+the package.
+.It Fl f
+Force removal of the package, even if a dependency is recorded or the
+deinstall or require script fails.
+.It Fl G
+Do not try to expand shell glob patterns in the
+.Ar pkg-name
+when selecting packages to be deleted (by default
+.Nm
+automatically expands shell glob patterns in the
+.Ar pkg-name ) .
+.It Fl x
+Treat the
+.Ar pkg-name
+as a regular expression and delete all packages whose names match
+that regular expression.  Multiple regular expressions could be
+provided, in that case
+.Nm
+deletes all packages that match at least one
+regular expression from the list.
+.It Fl r
+Recursive removal.  In addition to specified packages, delete all
+packages that depend on those packages as well.
+.El
+.Sh TECHNICAL DETAILS
+The
+.Nm
+utility
+does pretty much what it says.  It examines installed package records in
+.Pa /var/db/pkg/<pkg-name> ,
+deletes the package contents, and finally removes the package records.
+If the environment variable
+.Ev PKG_DBDIR
+is set, this overrides the
+.Pa /var/db/pkg/
+path shown above.
+.Pp
+If a package is required by other installed packages,
+.Nm
+will list those dependent packages and refuse to delete the package
+(unless the
+.Fl f
+option is given).
+.Pp
+If the package contains a
+.Ar require
+file (see
+.Xr pkg_create 1 ) ,
+then this is executed first as
+.Bd -ragged -offset indent -compact
+.Cm require
+.Ar <pkg-name>
+.Ar DEINSTALL
+.Ed
+(where
+.Ar pkg-name
+is the name of the package in question and
+.Ar DEINSTALL
+is a keyword denoting that this is a deinstallation)
+to see whether or not deinstallation should continue.  A non-zero exit
+status means no, unless the
+.Fl f
+option is specified.
+.Pp
+If a
+.Cm deinstall
+script exists for the package, it is executed before any files are removed.
+It is this script's responsibility to clean up any additional messy details
+around the package's installation, since all
+.Nm
+knows how to do is delete the files created in the original distribution.
+The
+.Nm deinstall
+script is called as:
+.Bd -ragged -offset indent -compact
+.Cm script
+.Ar <pkg-name>
+.Ar DEINSTALL
+.Ed
+where
+.Ar pkg-name
+is the name of the package in question and
+.Ar DEINSTALL
+is a keyword denoting this as the pre-deinstallation phase.
+.Pp
+.Sy Note :
+The
+.Ar DEINSTALL
+keyword will not appear if separate scripts for deinstall and post-deinstall
+are given during package creation time (using the
+.Fl k
+and
+.Fl K
+flags to
+.Xr pkg_create 1 ) .
+.Pp
+If a
+.Cm post-deinstall
+script exists for the package, it is executed
+.Cm after
+all files are removed.  It is this script's responsibility to clean up any
+additional messy details around the package's installation, and leave the
+system (hopefully) in the same state that it was prior to the installation
+of the package.
+.Pp
+The
+.Nm post-deinstall
+script is called as:
+.Bd -ragged -offset indent -compact
+.Cm script
+.Ar <pkg-name>
+.Ar POST-DEINSTALL
+.Ed
+where
+.Ar pkg-name
+is the name of the package in question and
+.Ar POST-DEINSTALL
+is a keyword denoting this as the post-deinstallation phase.
+.Pp
+.Sy Note :
+The
+.Ar POST-DEINSTALL
+keyword will not appear if separate scripts for deinstall and post-deinstall
+are given during package creation time (using the
+.Fl k
+and
+.Fl K
+flags to
+.Xr pkg_create 1 ) .
+.Pp
+Reasoning behind passing keywords such as
+.Ar DEINSTALL
+and
+.Ar POST-DEINSTALL
+is that it lets you potentially write only one program/script that handles
+all aspects of installation and deletion.
+.Pp
+But experience has proved that this is a lot more difficult to maintain and
+is not as advantageous as having separate scripts that handle each aspect of
+installation and deinstallation.
+.Pp
+All scripts are called with the environment variable
+.Ev PKG_PREFIX
+set to the installation prefix (see the
+.Fl p
+option above).  This allows a package author to write a script
+that reliably performs some action on the directory where the package
+is installed, even if the user might have changed it by specifying the
+.Fl p
+option when running
+.Nm
+or
+.Cm pkg_add .
+.Sh ENVIRONMENT
+The environment variable
+.Ev PKG_DBDIR
+specifies an alternative location for the installed package database.
+.Sh FILES
+.Bl -tag -width /var/db/pkg -compact
+.It Pa /var/db/pkg
+Default location of the installed package database.

+.Dt PKG_INFO 1
+.Os
+.Sh NAME
+.Nm pkg_info
+.Nd a utility for displaying information on software packages
+.Sh SYNOPSIS
+.Nm
+.Op Fl cdDfgGiIkLmopqrRsvVx
+.Op Fl e Ar package
+.Op Fl l Ar prefix
+.Op Fl t Ar template
+.Op Ar pkg-name ...
+.Nm
+.Op Fl q
+.Fl W Ar filename
+.Nm
+.Op Fl q
+.Fl O Ar origin
+.Nm
+.Fl a
+.Op Ar flags
+.Sh DESCRIPTION
+The
+.Nm
+command is used to dump out information for packages, either packed up in
+files with the
+.Xr pkg_create 1
+command or already installed on the system
+with the
+.Xr pkg_add 1
+command.
+.Sh OPTIONS
+The following command line options are supported:
+.Bl -tag -width indent
+.It Ar pkg-name ...
+The named packages are described.  A package name may either be the name of
+an installed package, the pathname to a package distribution file or a
+URL to an FTP available package.
+.It Fl a
+Show all currently installed packages.
+.It Fl v
+Turn on verbose output.
+.It Fl p
+Show the installation prefix for each package.
+.It Fl q
+Be
+.Dq quiet
+in emitting report headers and such, just dump the
+raw info (basically, assume a non-human reading).
+.It Fl c
+Show the (one line) comment field for each package.
+.It Fl d
+Show the long description field for each package.
+.It Fl D
+Show the install-message file for each package.
+.It Fl f
+Show the packing list instructions for each package.
+.It Fl g
+Show files that don't match the recorded checksum.
+.It Fl i
+Show the install script (if any) for each package.
+.It Fl I
+Show an index line for each package.  This option takes
+precedence over all other package formatting options.
+.It Fl k
+Show the de-install script (if any) for each package.
+.It Fl r
+Show the requirements script (if any) for each package.
+.It Fl R
+Show the list of installed packages which require each package.
+.It Fl m
+Show the mtree file (if any) for each package.
+.It Fl L
+Show the files within each package.  This is different from just
+viewing the packing list, since full pathnames for everything
+are generated.
+.It Fl s
+Show the total size occupied by files installed within each package.
+.It Fl o
+Show the
+.Dq origin
+path recorded on package generation.  This path
+intended to give an idea as to where the underlying port, from which
+package was generated, is located in the
+.Fx
+.Em "Ports Collection" .
+.It Fl G
+Do not try to expand shell glob patterns in the
+.Ar pkg-name
+when selecting packages to be displayed (by default
+.Nm
+automatically expands shell glob patterns in the
+.Ar pkg-name ) .
+.It Fl W
+For the specified
+.Ar filename
+argument show which package it belongs to.  If the file is not in the
+current directory, and does not have an absolute path, then the
+.Ev PATH
+is searched using
+.Xr which 1 .
+.It Fl O
+For the specified
+.Ar origin
+argument list all packages having this origin.
+.It Fl x
+Treat the
+.Ar pkg-name
+as a regular expression and display information only for packages
+whose names match that regular expression.  Multiple regular
+expressions could be provided, in that case
+.Nm
+displays information about all packages that match at least one
+regular expression from the list.
+.It Fl e Ar pkg-name
+If the package identified by
+.Ar pkg-name
+is currently installed, return 0, otherwise return 1.  This option
+allows you to easily test for the presence of another (perhaps
+prerequisite) package from a script.
+.It Fl l Ar str
+Prefix each information category header (see
+.Fl q )

+.Ar str .
+This is primarily of use to front-end programs who want to request a
+lot of different information fields at once for a package, but don't
+necessary want the output intermingled in such a way that they can't
+organize it.  This lets you add a special token to the start of

+Use

+as the input to

+when creating a

+By default, this is the string

+.Pa /tmp
+directory is limited.  Be sure to leave some number of `X' characters
+for

+to fill in with a unique ID.

+Note:  This should really not be necessary with

+To sign packages in a transparent way:
+gzip files can handle an extra field at the beginning that
+stores anything we wish.
+
+So it's just a question to choose a format for the signature, and to
+embed it there.
+
+We use the extra field to store signatures.  Each signature consists
+of a 6 bytes type marker, a 2 bytes length, followed by the signature
+itself.  We can potentially stack signatures: resign a signed archive
+by just prepending the new signature to the extra field.
+
+To check the first signature, the checker just needs to extract it, pass it
+off to the checking protocol (e.g. PGP), followed by the unsigned archive
+(e.g., regenerate the gzip header  without the first signature, then put
+the gzip data).
+
+* Signed archives just look like normal .tar.gz files, except for programs
+that use the extra field for their own purpose,
+* Possibility to grab the files off the net and extract stuff/verify
+signatures on the fly (just need to wedge the checker as an intermediate
+pipe)
+* Pretty simple, small portable code to be able to check signatures
+everywhere (the signer itself needs getpass and corresponding functionality)
+
+The scheme should be extensible to any compressed format which allows for
+extended headers.
+
+
+Thanks to Angelos D. Keromytis for pointing out I did not need to
+uncompress the archive to sign it, and to other members of the OpenBSD
+project for various reasons.

+X.509 notes:
+
+I added the ability to sign a package with an X.509 key, and to check
+against a stack of X.509 certificates.  This allows a "vendor" to
+distribute a system with one or more certificates pre-installed, and
+to add certificates in a signed package by appending them to the
+default certficiate stack.
+
+The X.509 signatures are stored in the gzip header in the same manner
+as other signatures.  This is known to compile against OpenSSL
+libraries on OpenBSD 2.7 and FreeBSD 5.0, your mileage may vary.

+.Dt PKG_SIGN 1
+.Os
+.Sh NAME
+.Nm pkg_sign ,
+.Nm pkg_check
+.Nd handle package signatures
+.Sh SYNOPSIS
+.Nm
+.Op Fl sc
+.Op Fl t Ar type
+.Op Fl u Ar id
+.Op Fl k Ar key
+.Op Ar
+.Nm pkg_check
+.Op Fl sc
+.Op Fl u Ar id
+.Op Fl k Ar cert
+.Op Ar
+.Sh DESCRIPTION
+The
+.Nm
+utility embeds a cryptographic signature within a gzip file
+.Ar file .
+.Ar type
+can be
+.Cm pgp
+(default),
+.Cm sha1 ,
+or
+.Cm x509 .
+If
+.Ar type
+is
+.Cm pgp ,
+it will always prompt you for a passphrase to unlock your private
+pgp key, even if you don't use a passphrase (which is a bad idea, anyway).
+If
+.Ar type
+is
+.Cm sha1 ,
+you must supply an
+.Ar id ,
+which will be recorded as the name of the package, and printed as the
+SHA1 checksum.
+.Pp
+The
+.Nm pkg_check
+utility checks that cryptographic signature.
+It currently disregards
+.Ar type
+and checks only the topmost signature.
+For
+.Cm sha1 ,
+it checksums the file
+and verifies that the result matches the list of checksums recorded in
+.Pa /var/db/pkg/SHA1 .
+.Pp
+Options
+.Fl s
+and
+.Fl c
+can be used to force package signing or signature checking mode.
+.Pp
+For
+.Cm pgp ,
+the
+.Ar id
+to use to sign the package or verify the signature can be forced with
+.Fl u .
+.Pp
+For
+.Cm x509 ,
+the signing key or verification certificate may be
+specified with the
+.Fl k
+option.  If not specified, packages are signed or verified with the
+default keys and certificates documented below.
+.Pp
+If
+.Ar file
+is a single dash
+.Pq Sq Fl
+or absent,
+.Nm
+reads from the standard input.
+.Pp
+Package signing uses a feature of the gzip format, namely that one can
+set a flag
+.Dv EXTRA_FIELD
+in the gzip header and store extra data between the gzip header and the
+compressed file proper.
+The
+.Ox
+signing scheme uses eight bytes markers such
+.Sq Li SIGPGP
++ length or
+.Sq CKSHA1
++ length for its signatures (those markers are conveniently
+eight bytes long).
+.Sh DIAGNOSTICS
+The
+.Nm
+and
+.Nm pkg_check
+utilities return with an exit code >0 if anything went wrong for any
+.Ar file .
+For
+.Nm pkg_check ,
+this usually indicates that the package is not signed, or that the
+signature is forged.
+.Bl -diag
+.It "File %s is already signed"
+There is a signature embedded within the gzip file already.
+The
+.Nm
+utility currently does not handle multiple signatures.
+.It "File %s is not a signed gzip file"
+This is an unsigned package.
+.It "File %s is not a gzip file"
+The program couldn't find a proper gzip header.
+.It "File %s contains an unknown extension"
+The extended area of the gzip file has been used for an unknown purpose.
+.It "File %s uses old signatures, no longer supported"
+The gzip file uses a very early version of package signing that was
+substantially slower.
+.El
+.Sh BUGS
+.Xr pgp 1
+is an ill-designed program, which is hard to interface with.
+For instance, the `separate signing scheme' it pretends to offer is
+useless, as it can't be used with pipes, so that
+.Nm pgp_sign
+needs to kludge it by knowing the length of a pgp signature, and invoking
+pgp in `seamless' signature mode, without compression of the main file,
+and just retrieving the signature.
+.Pp
+The checking scheme is little less convoluted, namely we rebuild the file
+that pgp expects on the fly.
+.Pp
+Paths to
+.Nm pgp
+and
+the checksum file are hard-coded to avoid tampering and hinder flexibility.
+.Sh FILES
+.Bl -tag -width "/usr/local/bin/pgp" -compact
+.It Pa file.sign
+Temporary file built by
+.Nm
+from
+.Ar file .
+.It Pa /usr/local/bin/pgp

+.Os
+.Sh NAME
+.Nm pkg_version
+.Nd summarize installed versions of packages
+.Sh SYNOPSIS
+.Nm
+.Op Fl hv
+.Op Fl l Ar limchar
+.Op Fl L Ar limchar
+.Op Fl s Ar string
+.Op Ar index
+.Nm
+.Op Fl t Ar version1 version2
+.Sh DESCRIPTION
+The
+.Nm
+command is used to produce a report of non-base software packages
+installed using the
+.Xr pkg_add 1
+command.
+.Pp
+Each package's version number is checked against one of two sources to
+see if that package may require updating.  If the package contains
+information about its origin in the
+.Fx
+ports tree, and a version number can be determined from the port's
+.Pa Makefile ,
+then the version number from the
+.Pa Makefile
+will be used to determine whether the installed package is up-to-date
+or requires updating.
+.Pp
+If no origin for a package can be found, or if the port's
+.Pa Makefile
+cannot be located,
+.Nm
+will search for the package in the ports collection index file
+(typically
+.Pa /usr/ports/INDEX ) .
+Any matching version number(s) there will be used to determine whether
+the installed package is up-to-date or requires updating.
+.Pp
+Generally, using the version number from a port's
+.Pa Makefile
+will provide a more accurate result, since, unlike the index file, it
+provides an unambiguous current version number, even when multiple
+versions of a port exist in the ports collection.
+Moreover, the ports collection index file is only updated at
+intervals, meaning that it may not completely reflect the version
+numbers of the software contained in the ports collection.
+.Pp
+Each package name is printed, along with a one-character status flag:
+.Bl -tag -width indent
+.It Li =
+The installed version of the package is current.
+.It Li \&<
+The installed version of the package is older than the current version.
+.It Li \&>
+The installed version of the package is newer than the current version.
+This situation can arise with an out-of-date index file, or when
+testing new ports.
+.It Li \&?
+The installed package does not appear in the index.
+This could be due to an out of date index or a package taken from a PR
+that has not yet been committed.
+.It Li *
+There are multiple versions of a particular software package
+listed in the index file.
+Examples from the
+.Fx
+ports collection are the Tcl toolkit or the
+.Tn EMACS
+editor.
+.It Li \&!
+The installed package exists in the index but for some reason,
+.Nm
+was unable to compare the version number of the installed package
+with the corresponding entry in the index.
+.El
+.Sh OPTIONS
+The
+.Nm
+utility supports several command-line arguments:
+.Bl -tag -width indent
+.It Fl h
+Print help message.
+.It Fl l
+Limit the output to those packages whose status flag matches the
+character(s) in
+.Ar limchar .
+More than one character can be specified in
+.Ar limchar .
+Note that because some of the status flag characters are also special
+to the shell, it is best to quote
+.Ar limchar
+with single quotes.
+.It Fl L
+Limit the output to those packages whose status flag doesn't match
+.Ar limchar .
+You may specify more than one character to match in
+.Ar limchar .
+Note that because some of the status flag characters are also special
+to the shell, it is best to quote

+The command below generates a report against
+the version numbers in the on-line ports collection:
+.Pp
+.Dl % pkg_version ftp://ftp.FreeBSD.org/pub/FreeBSD/branches/-current/ports/INDEX

+$FreeBSD$
+
+This file summarises changes made to ppp that effect
+its configuration.
+
+It does not describe new features, rather it attempts
+to answer any `this used to work, why doesn't it now?'
+questions.
+
+o The `set debug' command was replaced with `set log'.
+o The `set log LCP' command was split into LCP, IPCP and CCP logs.
+o Syslogd is used for logging.  /etc/syslog.conf must be updated.
+o LQR is disabled by default.
+o Openmode is active by default.
+o Users must be a member of group `network' for ppp access.  Furthermore,
+  they must be `allow'ed to run ppp via the `allow' command in the
+  configuration file.
+  For a brief period, ppp could only be run as root.
+o No diagnostic socket is created by default.  The `set server' command
+  must be used.
+o The diagnostic socket password must be specified *only* on the `set
+  server' command line.
+o When `set server' is used to re-select a diagnostic port, all existing
+  diagnostic connections are dropped.
+o pppd-deflate is now called deflate24.
+o Filter IPs of 0.0.0.0 have a default width of 0, not 32.
+o Errors in `add' and `delete' are logged as warnings rather than being
+  written to the TCP/IP log.
+o Any number of diagnostic prompts are allowed, and they are allowed in
+  interactive mode.
+o The default `device' is cuaa1, then cuaa0
+o A password of "*" in ppp.secret causes a passwd database lookup in
+  pap mode.
+o The value of the CONNECT environment variable is logged in the
+  utmp host field in -direct mode.
+o Out-of-sequence FSM packets (IPCP/LCP/CCP) are dropped by default.
+o Reconnect values are used after an LQR timeout.
+o ^C works on the parent in -background mode.
+o The dial/call/open command works asynchronously.  As a result, prompts
+  do not lose control while dialing.
+o The `display' command has been removed.  All information is available
+  with the appropriate `show' command.
+o Msext does not need to be enabled/disabled.  Setting the NBNS (set nbns)
+  will auto enable it.  The DNS side may be enabled/disabled, and if
+  enabled without a `set dns' (was `set ns') will use values from
+  /etc/resolv.conf.
+o Filters are now called `allow', `dial', `in' and `out'.  `set
+  ifilter ...' becomes `set filter in ...' etc.
+o Authname and Authkey may only be `set' in phase DEAD.
+o Set encrypt is no longer necessary.  Ppp will respond to M$CHAP
+  servers correctly if it's built with DES.
+o Throughput statistics are enabled by default.
+o `Set stopped' only has two parameters.  It's no longer possible to
+  have an IPCP stopped timer.
+o `Set timeout' only has one or two parameters.  Use `set lqrperiod' and
+  `set {lcp,ccp,ipcp,chap,pap}retry' for the other timers.  These timeout
+  values can be seen using the relevant show commands.
+o `set loopback' is now `enable/disable loopback'.
+o `show auto', `show loopback' and `show mtu' are all part of `show bundle'.
+o `show mru' is part of `show lcp'
+o `show msext' and `show vj' are part of `show ipcp'
+o `show reconnect' and `show redial' are part of `show link'
+o A signal 15 (TERM) will now shut down the link gracefully.
+o A signal 2 (HUP) will drop all links immediately.
+o Signal 30 (USR1) is now ignored.
+o Add & delete commands are not necessary in ppp.linkup if they are
+  `sticky routes' (ie, contain MYADDR or HISADDR).
+o LINK and CARRIER logging are no longer available.
+o Timer based DEBUG messages are now logged in the new TIMER log.
+o Ppp can use tun devices > tun255.
+o Protocol-compressed packets are accepted even if they were denied
+  at LCP negotiation time.
+o Passwords aren't logged when logging the ``set server'' line.
+o Command line options only need enough characters to uniquely identify
+  them.  -a == -auto, -dd == -ddial etc.  -interactive is also allowed.
+o If you don't like seeing additional interface aliases when running in
+  -auto -alias mode, add ``iface clear'' to your ppp.linkdown file -
+  check the sample file.
+o Ppp waits for 1 second before checking whether the device supports
+  carrier.  This is controllable with ``set cd''.
+o Random dial timeouts are now between 1 and 30 seconds inclusive rather
+  than between 0 and 29.
+o Ppp now accepts M$CHAP (as well as normal CHAP) by default.  If this
+  is not required, you must ``deny chap05 chap80''.
+o The ``set device'' command now expects each device to be specified as an
+  argument rather than concatentating all arguments and splitting based
+  on commas and spaces.
+o The ``show modem'' command is deprecated and has been changed to
+  ``show physical''.
+o The words ``host'' and ``port'' are no longer accepted by the ``set filter''
+  command.  Removing them should yield the same results as before.
+o The ``set weight'' command has been deprecated.  The ``set bandwidth''
+  command should now be used instead.
+o The ``set autoload'' command syntax and implementation have changed as the
+  old implementation was mis-designed and dysfunctional.
+o Ppp now waits either the full ``set cd'' time or until carrier is detected
+  before running the login script (whichever comes first).
+o The -alias flag has been deprecated.  The -nat flag should be used instead.
+o Unbalanced quotes in commands are now warned about and the entire command
+  is ignored.
+o It is now only necessary to escape the `-' character in chat scripts twice.
+  See the example files for details.
+o Environment variables and ~ are expanded on in commands
+o ``nat pptp'' is no longer necessary as this is now done transparently
+o The ``!'' at the start of chat scripts and authkey can be made literal
+  (rather than meaning execute) by doubling it to ``!!''.
+o MP autoload throughput measurements are now based on the maximum of input
+  and output averages rather than on the total.
+o When only one link is open in MP mode, MP link level compression is not
+  open and the peer MRU >= the peer MRRU, ppp sends outbound traffic as
+  PROTO_IP traffic rather than PROTO_MP.
+o MSCHAPv2 is now accepted by default.  If you don't wish to negotiate
+  this, you must explicitly deny it.
+o MPPE is enabled and accepted by default (although deflate and predictor1
+  are preferred.

+
+This file summarises changes made to ppp that effect
+This program was originally written by Toshiharu OHNO <tony-o@iij.ad.jp>,
+and was submitted to FreeBSD-2.0.5 by Atsushi Murai <amurai@spec.co.jp>.
+The original version was usually referred to as iij-ppp.
+
+Ppp is currently maintained under FreeBSD and OpenBSD by Brian Somers
+<brian@Awfulhak.org>.  The sources for both operating systems are the
+same except that the libalias code is built directly into ppp under
+OpenBSD, and the Makefiles vary per OS.
+
+The latest sources are available in FreeBSD-current and OpenBSD-current.
+An archive hacked so that it will build on just about any version of
+FreeBSD or OpenBSD is frequently generated and made available via
+http://www.Awfulhak.org/ppp.html.
+
+A FAQ is available at http://www.FreeBSD.org/FAQ/userppp.html.  It applies
+equally to OpenBSD as it does to FreeBSD.  The man page is quite extensive,
+and there are lots of examples in /usr/share/examples/ppp/.
+
+Ppp is still under development.  There is no official TODO list.

+User PPP NAT (Packet Aliasing)

+    6. Revision History for Aliasing Code
+
+
+
+1. Background
+
+User mode ppp has embedded NAT (Network Address Translation) code.
+Enabling this, either by the "-nat" command line option or the
+"nat enable yes" command in a ppp.conf file, makes the ppp host
+automatically NAT IP packets forwarded from a local network, making
+them appear to come from the ppp host machine.  Incoming packets
+from the outside world are then appropriately de-NAT'd.
+
+The process of NAT'ing involves both the IP address and the TCP or UDP
+port numbers. ICMP echo and timestamp packets are natted by their id
+numbers.  ICMP error messages can be properly directed by examining the
+fragment of the offending packet which is contained in the body of the
+message.
+
+This software was specifically meant to support users who have
+unregistered, private address IP networks (e.g. 192.168.0.x or 10.0.0.x
+addresses).  The ppp host can act as a gateway for these networks, and
+computers on the local area net will have some degree of Internet access
+without the need for a registered IP address.  Additionally, there will
+be no need for an Internet service provider to maintain routing tables
+for the local area network.
+
+A disadvantage of NAT is that machines on the local network,
+behind the ppp host, are not visible from the outside world.  They can
+establish TCP connections and make UDP inquiries (such as domain name
+service requests) but the connections seem to come from the ppp host
+itself.  There is, in effect, a partial firewall.  Of course, if this is
+what you want, the disadvantage becomes an advantage.
+
+A second disadvantage is that "IP encoding" protocols, which send IP
+address or port information within the data stream, are not supported
+for the cases where exception code exists.  This implementation has
+workarounds for FTP and IRC DCC, the most well known of the IP encoding
+protocols.  This frees users from depending on using the ftp passive
+mode and avoiding IRC DCC sends, as is sometimes the case with other
+masquerading solutions.
+
+The implementation supports all standard, non-encoding TCP and UDP protocols.
+Examples of these protocols are http, gopher and telnet. The standard UDP
+mode of Real-Audio is not presently supported, but the TCP mode does work
+correctly.
+
+The NAT code also handles many ICMP messages.  In particular,
+ping and traceroute are supported.
+
+
+
+2. Packet Aliasing Setup
+
+It is recommended that users first verify correct ppp operation without
+NAT enabled.  This will confirm that the ppp.conf file is
+properly set up and that there are no ppp problems. Then start ppp with
+the "-nat" option on the command line.  The user should verify that
+the ppp host can correctly connect to the Internet in NAT
+mode.  Finally, check that machines on the private network can access
+the Internet.
+
+The NAT software handles all packets, whether they come from
+the host or another computer on the local area network.  Thus, a correctly
+operating ppp host indicates that the software should work properly for
+other computers on the private network.
+
+If the ppp host can access the Internet, but other computers on the local
+network cannot, check that IP forwarding is enabled on the ppp host. Also,
+verify that the other computers use this machine as a gateway.  Of course,
+you should also verify that machines within the local area network
+communicate properly.  A common error is inconsistent subnet addresses
+and masks.
+
+
+
+3. New commands in ppp
+
+In order to control NAT behaviour in a simple manner (no need for
+recompilation), a new command has been added to ppp: nat.  This
+is in addition to the -nat command line option.  System managers and
+more experienced users may prefer to use the ppp command syntax
+within the ppp.conf file.  The nat command also allows NAT
+behaviour to be more precisely specified.
+
+The decision to add a command instead of extending 'set' or 'option' was
+to make obvious that these options only work when NAT is enabled.
+
+The syntax for 'nat' is
+
+    ppp>  nat option [yes|no]
+
+where option is given by one of the following templates.
+
+
+ - nat enable [yes|no]  (default no)
+
+Enable NAT functionality.  If disabled, no other NAT
+options will have any effect.  You should usually enable NAT
+before routing any packets over the link; good points are in the
+initial script or right before adding a route.  If you do not always
+want NAT, consider using the -nat option to ppp instead of this
+command.
+
+
+ - nat deny_incoming [yes|no] (default yes)
+
+Set to "yes" to disable all incoming connections.  This just drops
+connections to, for example, ftp, telnet or web servers.  The NAT
+mechanism prevents these connections. Technically, this option denies
+all incoming TCP and UDP requests, making the NAT software a
+fairly efficient one-way firewall.  The default is no, which will allow
+all incoming connections to telnetd, ftpd, etc.
+
+
+ - nat log [yes|no]
+
+Controls logging of NAT link creation to "/var/log/alias.log" - this
+is usually only useful if debugging a setup, to see if the bug is in
+the PPP NATing.  The debugging information is fairly limited, listing
+the number of NAT links open for different protocols.
+
+
+ - nat same_ports [yes|no] (default yes)
+
+When a connection is being established going through the NAT
+routines, it will normally have its port number changed to allow the
+NAT code to track it.  If same_ports is enabled, the NAT
+software attempts to keep the connection's source port unchanged.
+This will allow rsh, RPC and other specialised protocols to work
+_most of the time_, at least on the host machine.  Please, do not
+report this being unstable as a bug - it is a result of the way
+NAT has to work. TCP/IP was intended to have one IP address
+per machine.
+
+
+ - nat use_sockets [yes|no] (default yes)
+
+This is a fairly obscure option.  For the most part, the NAT
+software does not have to allocate system sockets when it chooses a
+NAT port number.  Under very specific circumstances, FTP data
+connections (which don't know the remote port number, though it is
+usually 20) and IRC DCC send (which doesn't know either the address or
+the port from which the connection will come), there can potentially be
+some interference with an open server socket having the same port number
+on the ppp host machine.  This possibility for interference only exists
+until the TCP connection has been acknowledged on both sides.  The safe
+option is yes, though fewer system resources are consumed by specifying
+no.
+
+
+ - nat unregistered_only [yes|no] (default no)
+
+NAT normally remaps all packets coming from the local area
+network to the ppp host machine address.  Set this option to only map
+addresses from the following standard ranges for private, unregistered
+addresses:
+
+                10.0.0.0     ->   10.255.255.255
+                172.16.0.0   ->   172.31.255.255
+                192.168.0.0  ->   192.168.255.255  */
+
+In the instance that there is a subnet of public addresses and another
+subnet of private addresses being routed by the ppp host, then only the
+packets on the private subnet will be NAT'd.
+
+
+- nat port <proto> <local addr>:<port>  <nat port>
+
+This command allows incoming traffic to <nat port> on the host
+machine to be redirected to a specific machine and port on the
+local area network.  One example of this would be:
+
+    nat port tcp 192.168.0.4:telnet  8066
+
+All traffic to port 8066 of the ppp host would then be sent to
+the telnet port (23) of machine 192.168.0.4.  Port numbers
+can either be designated numerically or by symbolic names
+listed in /etc/services.  Similarly, addresses can be either
+in dotted quad notation or in /etc/hosts.
+
+
+- nat addr <local addr> <public addr>
+
+This command allows traffic for a public IP address to be
+redirected to a machine on the local network.  This function
+is known as "static NAT".  An address assignment of 0 refers
+to the default address of the ppp host.  Normally static
+NAT is useful if your ISP has allocated a small block of
+IP addresses to the user, but it can even be used in the
+case of a single, dynamically allocated IP address:
+
+    nat addr 10.0.0.8 0
+
+The above command would redirect all incoming traffic to
+machine 10.0.0.8.
+
+If several address NATs specify the same public address
+as follows
+
+    nat addr 192.168.0.2  public_addr
+    nat addr 192.168.0.3  public_addr
+    nat addr 192.168.0.4  public_addr
+
+then incoming traffic will be directed to the last
+translated local address (192.168.0.4), but outgoing
+traffic to the first two addresses will still be NAT'd
+to the specified public address.
+
+
+
+4. Future Work
+
+What is called NAT here has been variously called masquerading, packet
+aliasing and transparent proxying by others.  It is an extremely useful
+function to many users, but it is also necessarily imperfect.  The
+occasional IP-encoding protocols always need workarounds (hacks).
+Users who are interested in supporting new IP-encoding protocols
+can follow the examples of alias_ftp.c and alias_irc.c.
+
+ICMP error messages are currently handled only in the incoming direction.
+A handler needs to be added to correctly NAT outgoing error messages.
+
+IRC and FTP exception handling make reasonable, though not strictly correct
+assumptions, about how IP encoded messages will appear in the control
+stream.  Programmers may wish to consider how to make this process more
+robust.
+
+The NAT engine (alias.c, alias_db.c, alias_ftp.c, alias_irc.c
+and alias_util.c) runs in user space, and is intended to be both portable
+and reusable for interfaces other than ppp.  To access the basic engine
+only requires four simple function calls (initialisation, communication of
+host address, outgoing NAT and incoming de-NATing).

+6. Revision History for Aliasing Code
+
+Version 1.0: August 11, 1996 (cjm)
+
+Version 1.1:  August 20, 1996  (cjm)
+    PPP host accepts incoming connections for ports 0 to 1023.
+
+Version 1.2:  September 7, 1996 (cjm)
+    Fragment handling error in alias_db.c corrected.
+
+Version 1.3: September 15, 1996 (cjm)
+    - Generalised mechanism for handling incoming connections
+      (no more 0 to 1023 restriction).
+    - Increased ICMP support (will handle traceroute now).
+    - Improved TCP close connection logic.
+
+Version 1.4: September 16, 1996
+    Can't remember (this version only lasted a day -- cjm).
+
+Version 1.5: September 17, 1996 (cjm)
+    Corrected error in handling incoming UDP packets
+    with zero checksum.
+
+Version 1.6: September 18, 1996
+    Simplified ICMP data storage.  Will now handle
+    tracert from Win95 as well as FreeBSD traceroute.
+
+Version 1.7: January 9, 1997 (cjm)
+    - Reduced malloc() activity for ICMP echo and
+      timestamp requests.
+    - Added handling for out-of-order IP fragments.
+    - Switched to differential checksum computation
+      for IP headers (TCP, UDP and ICMP checksums
+      were already differential).
+    - Accepts FTP data connections from other than
+      port 20.  This allows one ftp connections
+      from two hosts which are both running packet
+      aliasing.
+
+Version 1.8: January 14, 1997 (cjm)
+    - Fixed data type error in function StartPoint()
+      in alias_db.c (this bug did not exist before v1.7)
+
+Version 1.8b: January 16, 1997 (Eivind Eklund <perhaps@yes.no>)
+    - Upgraded base PPP version to be the source code from
+      FreeBSD 2.1.6, with additional security patches.  This
+      version should still be possible to run on 2.1.5, though -
+      I've run it with a 2.1.5 kernel without problems.
+      (Update done with the permission of cjm)
+
+Version 1.9: February 1, 1997 (Eivind Eklund <perhaps@yes.no>)
+    - Added support for IRC DCC (ee)
+    - Changed the aliasing routines to use ANSI style throughout -
+      minor API changes for integration with other programs than PPP (ee)
+    - Changed the build process, making all options switchable
+      from the Makefile (ee)
+    - Fixed minor security hole in alias_ftp.c for other applications
+      of the aliasing software.  Hole could _not_ manifest in
+      PPP+pktAlias, but could potentially manifest in other
+      applications of the aliasing. (ee)
+    - Connections initiated from packet aliasing host machine will
+      not have their port number aliased unless it conflicts with
+      an aliasing port already being used. (There is an option to
+      disable this for debugging) (cjm)
+    - Sockets will be allocated in cases where there might be
+      port interference with the host machine.  This can be disabled
+      in cases where the ppp host will be acting purely as a
+      masquerading router and not generate any traffic of its own.
+      (cjm)
+
+Version 2.0: March, 1997 (cjm)
+    - Incoming packets which are not recognised by the packet
+      aliasing engine are now completely dropped in ip.c.
+    - Aliasing links are cleared when a host interface address
+      changes (due to re-dial and dynamic address allocation).
+    - PacketAliasPermanentLink() API added.
+    - Option for only aliasing private, unregistered IP addresses
+      added.
+    - Substantial rework to the aliasing lookup engine.
+
+Version 2.1: May, 1997 (cjm)
+    - Continuing rework to the aliasing lookup engine to support
+      multiple incoming addresses and static NAT.
+    - Now supports outgoing as well as incoming ICMP error messages/
+    - PPP commands to support address and port redirection.

+.Sh NAME
+.Nm ppp
+.Nd Point to Point Protocol (a.k.a. user-ppp)
+.Sh SYNOPSIS
+.Nm
+.Op Fl Va mode
+.Op Fl nat
+.Op Fl quiet
+.Op Fl unit Ns Ar N
+.Op Ar system ...
+.Sh DESCRIPTION
+This is a user process
+.Em PPP
+software package.
+Normally,
+.Em PPP
+is implemented as a part of the kernel (e.g., as managed by
+.Xr pppd 8 )
+and it's thus somewhat hard to debug and/or modify its behaviour.
+However, in this implementation
+.Em PPP
+is done as a user process with the help of the
+tunnel device driver (tun).
+.Pp
+The
+.Fl nat
+flag does the equivalent of a
+.Dq nat enable yes ,
+enabling
+.Nm Ns No 's
+network address translation features.
+This allows
+.Nm
+to act as a NAT or masquerading engine for all machines on an internal
+LAN.
+ifdef({LOCALNAT},{},{Refer to
+.Xr libalias 3
+for details on the technical side of the NAT engine.
+})dnl
+Refer to the
+.Sx NETWORK ADDRESS TRANSLATION (PACKET ALIASING)
+section of this manual page for details on how to configure NAT in
+.Nm .
+.Pp
+The
+.Fl quiet
+flag tells
+.Nm
+to be silent at startup rather than displaying the mode and interface
+to standard output.
+.Pp
+The
+.Fl unit
+flag tells
+.Nm
+to only attempt to open
+.Pa /dev/tun Ns Ar N .
+Normally,
+.Nm
+will start with a value of 0 for
+.Ar N ,
+and keep trying to open a tunnel device by incrementing the value of
+.Ar N
+by one each time until it succeeds.
+If it fails three times in a row
+because the device file is missing, it gives up.
+.Pp
+The following
+.Va mode Ns No s
+are understood by
+.Nm :
+.Bl -tag -width XXX -offset XXX
+.It Fl auto
+.Nm
+opens the tun interface, configures it then goes into the background.
+The link isn't brought up until outgoing data is detected on the tun
+interface at which point
+.Nm
+attempts to bring up the link.
+Packets received (including the first one) while
+.Nm
+is trying to bring the link up will remain queued for a default of
+2 minutes.
+See the
+.Dq set choked
+command below.
+.Pp
+In
+.Fl auto
+mode, at least one
+.Dq system
+must be given on the command line (see below) and a
+.Dq set ifaddr
+must be done in the system profile that specifies a peer IP address to
+use when configuring the interface.
+Something like
+.Dq 10.0.0.1/0
+is usually appropriate.
+See the
+.Dq pmdemand
+system in
+.Pa /usr/share/examples/ppp/ppp.conf.sample
+for an example.
+.It Fl background
+Here,
+.Nm
+attempts to establish a connection with the peer immediately.
+If it succeeds,
+.Nm
+goes into the background and the parent process returns an exit code
+of 0.
+If it fails,
+.Nm
+exits with a non-zero result.
+.It Fl foreground
+In foreground mode,
+.Nm
+attempts to establish a connection with the peer immediately, but never
+becomes a daemon.
+The link is created in background mode.
+This is useful if you wish to control
+.Nm Ns No 's
+invocation from another process.
+.It Fl direct
+This is used for receiving incoming connections.
+.Nm
+ignores the
+.Dq set device
+line and uses descriptor 0 as the link.
+.Pp
+If callback is configured,
+.Nm
+will use the
+.Dq set device
+information when dialing back.
+.It Fl dedicated
+This option is designed for machines connected with a dedicated
+wire.
+.Nm
+will always keep the device open and will never use any configured
+chat scripts.
+.It Fl ddial
+This mode is equivalent to
+.Fl auto
+mode except that
+.Nm
+will bring the link back up any time it's dropped for any reason.
+.It Fl interactive
+This is a no-op, and gives the same behaviour as if none of the above
+modes have been specified.
+.Nm
+loads any sections specified on the command line then provides an
+interactive prompt.
+.El
+.Pp
+One or more configuration entries or systems
+(as specified in
+.Pa /etc/ppp/ppp.conf )
+may also be specified on the command line.
+.Nm
+will read the
+.Dq default
+system from
+.Pa /etc/ppp/ppp.conf
+at startup, followed by each of the systems specified on the command line.
+.Sh Major Features
+.Bl -diag
+.It Provides an interactive user interface.
+Using its command mode, the user can
+easily enter commands to establish the connection with the remote end, check
+the status of connection and close the connection.
+All functions can also be optionally password protected for security.
+.It Supports both manual and automatic dialing.
+Interactive mode has a
+.Dq term
+command which enables you to talk to the device directly.
+When you are connected to the remote peer and it starts to talk
+.Em PPP ,
+.Nm
+detects it and switches to packet mode automatically.
+Once you have
+determined the proper sequence for connecting with the remote host, you
+can write a chat script to {define} the necessary dialing and login
+procedure for later convenience.
+.It Supports on-demand dialup capability.
+By using
+.Fl auto
+mode,
+.Nm
+will act as a daemon and wait for a packet to be sent over the
+.Em PPP
+link.
+When this happens, the daemon automatically dials and establishes the
+connection.
+In almost the same manner
+.Fl ddial
+mode (direct-dial mode) also automatically dials and establishes the
+connection.
+However, it differs in that it will dial the remote site
+any time it detects the link is down, even if there are no packets to be
+sent.
+This mode is useful for full-time connections where we worry less
+about line charges and more about being connected full time.
+A third
+.Fl dedicated
+mode is also available.
+This mode is targeted at a dedicated link between two machines.
+.Nm
+will never voluntarily quit from dedicated mode - you must send it the
+.Dq quit all
+command via its diagnostic socket.
+A
+.Dv SIGHUP
+will force an LCP renegotiation, and a
+.Dv SIGTERM
+will force it to exit.
+.It Supports client callback.
+.Nm
+can use either the standard LCP callback protocol or the Microsoft
+CallBack Control Protocol (ftp://ftp.microsoft.com/developr/rfc/cbcp.txt).
+.It Supports NAT or packet aliasing.
+Packet aliasing (a.k.a. IP masquerading) allows computers on a
+private, unregistered network to access the Internet.
+The
+.Em PPP
+host acts as a masquerading gateway.
+IP addresses as well as TCP and
+UDP port numbers are NAT'd for outgoing packets and de-NAT'd for
+returning packets.
+.It Supports background PPP connections.
+In background mode, if
+.Nm
+successfully establishes the connection, it will become a daemon.
+Otherwise, it will exit with an error.
+This allows the setup of
+scripts that wish to execute certain commands only if the connection
+is successfully established.
+.It Supports server-side PPP connections.
+In direct mode,
+.Nm
+acts as server which accepts incoming
+.Em PPP
+connections on stdin/stdout.
+.It "Supports PAP and CHAP (rfc 1994, 2433 and 2759) authentication.
+With PAP or CHAP, it is possible to skip the Unix style
+.Xr login 1
+procedure, and use the
+.Em PPP
+protocol for authentication instead.
+If the peer requests Microsoft CHAP authentication and
+.Nm
+is compiled with DES support, an appropriate MD4/DES response will be
+made.
+.It Supports RADIUS (rfc 2138 & 2548) authentication.
+An extension to PAP and CHAP,
+.Em \&R Ns No emote
+.Em \&A Ns No ccess
+.Em \&D Ns No ial
+.Em \&I Ns No n
+.Em \&U Ns No ser
+.Em \&S Ns No ervice
+allows authentication information to be stored in a central or
+distributed database along with various per-user framed connection
+characteristics.
+ifdef({LOCALRAD},{},{If
+.Xr libradius 3
+is available at compile time,
+.Nm
+will use it to make
+.Em RADIUS
+requests when configured to do so.
+})dnl
+.It Supports Proxy Arp.
+.Nm
+can be configured to make one or more proxy arp entries on behalf of
+the peer.
+This allows routing from the peer to the LAN without
+configuring each machine on that LAN.
+.It Supports packet filtering.
+User can {define} four kinds of filters: the
+.Em in
+filter for incoming packets, the
+.Em out
+filter for outgoing packets, the
+.Em dial
+filter to {define} a dialing trigger packet and the
+.Em alive
+filter for keeping a connection alive with the trigger packet.
+.It Tunnel driver supports bpf.
+The user can use
+.Xr tcpdump 1
+to check the packet flow over the
+.Em PPP
+link.
+.It Supports PPP over TCP and PPP over UDP.
+If a device name is specified as
+.Em host Ns No : Ns Em port Ns
+.Xo
+.Op / Ns tcp|udp ,
+.Xc
+.Nm
+will open a TCP or UDP connection for transporting data rather than using a
+conventional serial device.
+UDP connections force
+.Nm
+into synchronous mode.
+.It Supports PPP over ISDN.
+If
+.Nm
+is given a raw B-channel i4b device to open as a link, it's able to talk
+to the
+.Xr isdnd 8
+daemon to establish an ISDN connection.
+.It Supports PPP over Ethernet (rfc 2516).
+If
+.Nm
+is given a device specification of the format
+.No PPPoE: Ns Ar iface Ns Xo
+.Op \&: Ns Ar provider Ns
+.Xc
+and if
+.Xr netgraph 4
+is available,
+.Nm
+will attempt talk
+.Em PPP
+over Ethernet to
+.Ar provider
+using the
+.Ar iface
+network interface.
+.Pp
+On systems that do not support
+.Xr netgraph 4 ,
+an external program such as
+.Xr pppoe 8
+may be used.
+.It "Supports IETF draft Predictor-1 (rfc 1978) and DEFLATE (rfc 1979) compression."
+.Nm
+supports not only VJ-compression but also Predictor-1 and DEFLATE compression.
+Normally, a modem has built-in compression (e.g., v42.bis) and the system
+may receive higher data rates from it as a result of such compression.
+While this is generally a good thing in most other situations, this
+higher speed data imposes a penalty on the system by increasing the
+number of serial interrupts the system has to process in talking to the
+modem and also increases latency.
+Unlike VJ-compression, Predictor-1 and DEFLATE compression pre-compresses
+.Em all
+network traffic flowing through the link, thus reducing overheads to a
+minimum.
+.It Supports Microsoft's IPCP extensions (rfc 1877).
+Name Server Addresses and NetBIOS Name Server Addresses can be negotiated
+with clients using the Microsoft
+.Em PPP
+stack (i.e., Win95, WinNT)
+.It Supports Multi-link PPP (rfc 1990)
+It is possible to configure
+.Nm
+to open more than one physical connection to the peer, combining the
+bandwidth of all links for better throughput.
+.It Supports MPPE (draft-ietf-pppext-mppe)
+MPPE is Microsoft Point to Point Encryption scheme.
+It is possible to configure
+.Nm
+to participate in Microsoft's Windows VPN.
+For now,
+.Nm
+can only get encryption keys from CHAP 81 authentication.
+.Nm
+must be compiled with DES for MPPE to operate.
+.It Supports IPV6CP (rfc 2023).
+An IPv6 connection can be made in addition to or instead of the normal
+IPv4 connection.
+.El
+.Sh PERMISSIONS
+.Nm
+is installed as user
+.Dv root
+and group
+.Dv network ,
+with permissions
+.Dv 04554 .
+By default,
+.Nm
+will not run if the invoking user id is not zero.
+This may be overridden by using the
+.Dq allow users
+command in
+.Pa /etc/ppp/ppp.conf .
+When running as a normal user,
+.Nm
+switches to user id 0 in order to alter the system routing table, set up
+system lock files and read the ppp configuration files.
+All external commands (executed via the "shell" or "!bg" commands) are executed
+as the user id that invoked
+.Nm .
+Refer to the
+.Sq ID0
+logging facility if you're interested in what exactly is done as user id
+zero.
+.Sh GETTING STARTED
+When you first run
+.Nm
+you may need to deal with some initial configuration details.
+.Bl -bullet
+.It
+Your kernel must {include} a tunnel device (the GENERIC kernel includes
+one by default).
+If it doesn't, or if you require more than one tun
+interface, you'll need to rebuild your kernel with the following line in
+your kernel configuration file:
+.Pp
+.Dl pseudo-device tun N
+.Pp
+where
+.Ar N
+is the maximum number of
+.Em PPP
+connections you wish to support.
+.It
+Check your
+.Pa /dev
+directory for the tunnel device entries
+.Pa /dev/tunN ,
+where
+.Sq N
+represents the number of the tun device, starting at zero.
+If they don't exist, you can create them by running "sh ./MAKEDEV tunN".
+This will create tun devices 0 through
+.Ar N .
+.It
+Make sure that your system has a group named
+.Dq network
+in the
+.Pa /etc/group
+file and that the group contains the names of all users expected to use
+.Nm .
+Refer to the
+.Xr group 5
+manual page for details.
+Each of these users must also be given access using the
+.Dq allow users
+command in
+.Pa /etc/ppp/ppp.conf .
+.It
+Create a log file.
+.Nm
+uses
+.Xr syslog 3
+to log information.
+A common log file name is
+.Pa /var/log/ppp.log .
+To make output go to this file, put the following lines in the
+.Pa /etc/syslog.conf
+file:
+.Bd -literal -offset indent
+!ppp
+*.*<TAB>/var/log/ppp.log
+.Ed
+.Pp
+It is possible to have more than one
+.Em PPP
+log file by creating a link to the
+.Nm
+executable:
+.Pp
+.Dl # cd /usr/sbin
+.Dl # ln ppp ppp0
+.Pp
+and using
+.Bd -literal -offset indent
+!ppp0
+*.*<TAB>/var/log/ppp0.log
+.Ed
+.Pp
+in
+.Pa /etc/syslog.conf .
+Don't forget to send a
+.Dv HUP
+signal to
+.Xr syslogd 8
+after altering
+.Pa /etc/syslog.conf .
+.It
+Although not strictly relevant to
+.Nm Ns No 's
+operation, you should configure your resolver so that it works correctly.
+This can be done by configuring a local DNS
+(using
+.Xr named 8 )
+or by adding the correct
+.Sq nameserver
+lines to the file
+.Pa /etc/resolv.conf .
+Refer to the
+.Xr resolv.conf 5
+manual page for details.
+.Pp
+Alternatively, if the peer supports it,
+.Nm
+can be configured to ask the peer for the nameserver address(es) and to
+update
+.Pa /etc/resolv.conf
+automatically.
+Refer to the
+.Dq enable dns
+and
+.Dq resolv
+commands below for details.
+.El
+.Sh MANUAL DIALING
+In the following examples, we assume that your machine name is
+.Dv awfulhak .
+when you invoke
+.Nm
+(see
+.Sx PERMISSIONS
+above) with no arguments, you are presented with a prompt:
+.Bd -literal -offset indent
+ppp ON awfulhak>
+.Ed
+.Pp
+The
+.Sq ON
+part of your prompt should always be in upper case.
+If it is in lower case, it means that you must supply a password using the
+.Dq passwd
+command.
+This only ever happens if you connect to a running version of
+.Nm
+and have not authenticated yourself using the correct password.
+.Pp
+You can start by specifying the device name and speed:
+.Bd -literal -offset indent
+ppp ON awfulhak> set device /dev/cuaa0
+ppp ON awfulhak> set speed 38400
+.Ed
+.Pp
+Normally, hardware flow control (CTS/RTS) is used.
+However, under
+certain circumstances (as may happen when you are connected directly
+to certain PPP-capable terminal servers), this may result in
+.Nm
+hanging as soon as it tries to write data to your communications link
+as it is waiting for the CTS (clear to send) signal - which will never
+come.
+Thus, if you have a direct line and can't seem to make a
+connection, try turning CTS/RTS off with
+.Dq set ctsrts off .
+If you need to do this, check the
+.Dq set accmap
+description below too - you'll probably need to
+.Dq set accmap 000a0000 .
+.Pp
+Usually, parity is set to
+.Dq none ,
+and this is
+.Nm Ns No 's
+default.
+Parity is a rather archaic error checking mechanism that is no
+longer used because modern modems do their own error checking, and most
+link-layer protocols (that's what
+.Nm
+is) use much more reliable checking mechanisms.
+Parity has a relatively
+huge overhead (a 12.5% increase in traffic) and as a result, it is always
+disabled
+(set to
+.Dq none )
+when
+.Dv PPP
+is opened.
+However, some ISPs (Internet Service Providers) may use
+specific parity settings at connection time (before
+.Dv PPP
+is opened).
+Notably, Compuserve insist on even parity when logging in:
+.Bd -literal -offset indent
+ppp ON awfulhak> set parity even
+.Ed
+.Pp
+You can now see what your current device settings look like:
+.Bd -literal -offset indent
+ppp ON awfulhak> show physical
+Name: deflink
+ State:           closed
+ Device:          N/A
+ Link Type:       interactive
+ Connect Count:   0
+ Queued Packets:  0
+ Phone Number:    N/A
+
+Defaults:
+ Device List:     /dev/cuaa0
+ Characteristics: 38400bps, cs8, even parity, CTS/RTS on
+
+Connect time: 0 secs
+0 octets in, 0 octets out
+Overall 0 bytes/sec
+ppp ON awfulhak>
+.Ed
+.Pp
+The term command can now be used to talk directly to the device:
+.Bd -literal -offset indent
+ppp ON awfulhak> term
+at
+OK
+atdt123456
+CONNECT
+login: myispusername
+Password: myisppassword
+Protocol: ppp
+.Ed
+.Pp
+When the peer starts to talk in
+.Em PPP ,
+.Nm
+detects this automatically and returns to command mode.
+.Bd -literal -offset indent
+ppp ON awfulhak>               # No link has been established
+Ppp ON awfulhak>               # We've connected & finished LCP
+PPp ON awfulhak>               # We've authenticated
+PPP ON awfulhak>               # We've agreed IP numbers
+.Ed
+.Pp
+If it does not, it's probable that the peer is waiting for your end to
+start negotiating.
+To force
+.Nm
+to start sending
+.Em PPP
+configuration packets to the peer, use the
+.Dq ~p
+command to drop out of terminal mode and enter packet mode.
+.Pp
+If you never even receive a login prompt, it is quite likely that the
+peer wants to use PAP or CHAP authentication instead of using Unix-style
+login/password authentication.
+To set things up properly, drop back to
+the prompt and set your authentication name and key, then reconnect:
+.Bd -literal -offset indent
+~.
+ppp ON awfulhak> set authname myispusername
+ppp ON awfulhak> set authkey myisppassword
+ppp ON awfulhak> term
+at
+OK
+atdt123456
+CONNECT
+.Ed
+.Pp
+You may need to tell ppp to initiate negotiations with the peer here too:
+.Bd -literal -offset indent
+~p
+ppp ON awfulhak>               # No link has been established
+Ppp ON awfulhak>               # We've connected & finished LCP
+PPp ON awfulhak>               # We've authenticated
+PPP ON awfulhak>               # We've agreed IP numbers
+.Ed
+.Pp
+You are now connected!
+Note that
+.Sq PPP
+in the prompt has changed to capital letters to indicate that you have
+a peer connection.
+If only some of the three Ps go uppercase, wait until
+either everything is uppercase or lowercase.
+If they revert to lowercase, it means that
+.Nm
+couldn't successfully negotiate with the peer.
+A good first step for troubleshooting at this point would be to
+.Bd -literal -offset indent
+ppp ON awfulhak> set log local phase lcp ipcp
+.Ed
+.Pp
+and try again.
+Refer to the
+.Dq set log
+command description below for further details.
+If things fail at this point,
+it is quite important that you turn logging on and try again.
+It is also
+important that you note any prompt changes and report them to anyone trying
+to help you.
+.Pp
+When the link is established, the show command can be used to see how
+things are going:
+.Bd -literal -offset indent
+PPP ON awfulhak> show physical
+* Modem related information is shown here *
+PPP ON awfulhak> show ccp
+* CCP (compression) related information is shown here *
+PPP ON awfulhak> show lcp
+* LCP (line control) related information is shown here *
+PPP ON awfulhak> show ipcp
+* IPCP (IP) related information is shown here *
+PPP ON awfulhak> show ipv6cp
+* IPV6CP (IPv6) related information is shown here *
+PPP ON awfulhak> show link
+* Link (high level) related information is shown here *
+PPP ON awfulhak> show bundle
+* Logical (high level) connection related information is shown here *
+.Ed
+.Pp
+At this point, your machine has a host route to the peer.
+This means
+that you can only make a connection with the host on the other side
+of the link.
+If you want to add a default route entry (telling your
+machine to send all packets without another routing entry to the other
+side of the
+.Em PPP
+link), enter the following command:
+.Bd -literal -offset indent
+PPP ON awfulhak> add default HISADDR
+.Ed
+.Pp
+The string
+.Sq HISADDR
+represents the IP address of the connected peer.
+If the
+.Dq add
+command fails due to an existing route, you can overwrite the existing
+route using
+.Bd -literal -offset indent
+PPP ON awfulhak> add! default HISADDR
+.Ed
+.Pp
+This command can also be executed before actually making the connection.
+If a new IP address is negotiated at connection time,
+.Nm
+will update your default route accordingly.
+.Pp
+You can now use your network applications (ping, telnet, ftp etc.)
+in other windows or terminals on your machine.
+If you wish to reuse the current terminal, you can put
+.Nm
+into the background using your standard shell suspend and background
+commands (usually
+.Dq ^Z
+followed by
+.Dq bg ) .
+.Pp
+Refer to the
+.Sx PPP COMMAND LIST
+section for details on all available commands.
+.Sh AUTOMATIC DIALING
+To use automatic dialing, you must prepare some Dial and Login chat scripts.
+See the example definitions in
+.Pa /usr/share/examples/ppp/ppp.conf.sample
+(the format of
+.Pa /etc/ppp/ppp.conf
+is pretty simple).
+Each line contains one comment, inclusion, label or command:
+.Bl -bullet
+.It
+A line starting with a
+.Pq Dq #
+character is treated as a comment line.
+Leading whitespace are ignored when identifying comment lines.
+.It
+An inclusion is a line beginning with the word
+.Sq {!include} .
+It must have one argument - the file to {include}.
+You may wish to
+.Dq {!include} ~/.ppp.conf
+for compatibility with older versions of
+.Nm .
+.It
+A label name starts in the first column and is followed by
+a colon
+.Pq Dq \&: .
+.It
+A command line must contain a space or tab in the first column.
+.El
+.Pp
+The
+.Pa /etc/ppp/ppp.conf
+file should consist of at least a
+.Dq default
+section.
+This section is always executed.
+It should also contain
+one or more sections, named according to their purpose, for example,
+.Dq MyISP
+would represent your ISP, and
+.Dq ppp-in
+would represent an incoming
+.Nm
+configuration.
+You can now specify the destination label name when you invoke
+.Nm .
+Commands associated with the
+.Dq default
+label are executed, followed by those associated with the destination
+label provided.
+When
+.Nm
+is started with no arguments, the
+.Dq default
+section is still executed.
+The load command can be used to manually load a section from the
+.Pa /etc/ppp/ppp.conf
+file:
+.Bd -literal -offset indent
+ppp ON awfulhak> load MyISP
+.Ed
+.Pp
+Note, no action is taken by
+.Nm
+after a section is loaded, whether it's the result of passing a label on
+the command line or using the
+.Dq load
+command.
+Only the commands specified for that label in the configuration
+file are executed.
+However, when invoking
+.Nm
+with the
+.Fl background ,
+.Fl ddial ,
+or
+.Fl dedicated
+switches, the link mode tells
+.Nm
+to establish a connection.
+Refer to the
+.Dq set mode
+command below for further details.
+.Pp
+Once the connection is made, the
+.Sq ppp
+portion of the prompt will change to
+.Sq PPP :
+.Bd -literal -offset indent
+# ppp MyISP
+\&...
+ppp ON awfulhak> dial
+Ppp ON awfulhak>
+PPp ON awfulhak>
+PPP ON awfulhak>
+.Ed
+.Pp
+The Ppp prompt indicates that
+.Nm
+has entered the authentication phase.
+The PPp prompt indicates that
+.Nm
+has entered the network phase.
+The PPP prompt indicates that
+.Nm
+has successfully negotiated a network layer protocol and is in
+a usable state.
+.Pp
+If the
+.Pa /etc/ppp/ppp.linkup
+file is available, its contents are executed
+when the
+.Em PPP
+connection is established.
+See the provided
+.Dq pmdemand
+example in
+.Pa /usr/share/examples/ppp/ppp.conf.sample
+which runs a script in the background after the connection is established
+(refer to the
+.Dq shell
+and
+.Dq bg
+commands below for a description of possible substitution strings).
+Similarly, when a connection is closed, the contents of the
+.Pa /etc/ppp/ppp.linkdown
+file are executed.
+Both of these files have the same format as
+.Pa /etc/ppp/ppp.conf .
+.Pp
+In previous versions of
+.Nm ,
+it was necessary to re-add routes such as the default route in the
+.Pa ppp.linkup
+file.
+.Nm
+supports
+.Sq sticky routes ,
+where all routes that contain the
+.Dv HISADDR ,
+.Dv MYADDR ,
+.Dv HISADDR6
+or
+.Dv MYADDR6
+literals will automatically be updated when the values of these variables
+change.
+.Sh BACKGROUND DIALING
+If you want to establish a connection using
+.Nm
+non-interactively (such as from a
+.Xr crontab 5
+entry or an
+.Xr at 1
+job) you should use the
+.Fl background
+option.
+When
+.Fl background
+is specified,
+.Nm
+attempts to establish the connection immediately.
+If multiple phone
+numbers are specified, each phone number will be tried once.
+If the attempt fails,
+.Nm
+exits immediately with a non-zero exit code.
+If it succeeds, then
+.Nm
+becomes a daemon, and returns an exit status of zero to its caller.
+The daemon exits automatically if the connection is dropped by the
+remote system, or it receives a
+.Dv TERM
+signal.
+.Sh DIAL ON DEMAND
+Demand dialing is enabled with the
+.Fl auto
+or
+.Fl ddial
+options.
+You must also specify the destination label in
+.Pa /etc/ppp/ppp.conf
+to use.
+It must contain the
+.Dq set ifaddr
+command to {define} the remote peers IP address.
+(refer to
+.Pa /usr/share/examples/ppp/ppp.conf.sample )
+.Bd -literal -offset indent
+# ppp -auto pmdemand
+.Ed
+.Pp
+When
+.Fl auto
+or
+.Fl ddial
+is specified,
+.Nm
+runs as a daemon but you can still configure or examine its
+configuration by using the
+.Dq set server
+command in
+.Pa /etc/ppp/ppp.conf ,
+(for example,
+.Dq Li "set server +3000 mypasswd" )
+and connecting to the diagnostic port as follows:
+.Bd -literal -offset indent
+# pppctl 3000	(assuming tun0)
+Password:
+PPP ON awfulhak> show who
+tcp (127.0.0.1:1028) *
+.Ed
+.Pp
+The
+.Dq show who
+command lists users that are currently connected to
+.Nm
+itself.
+If the diagnostic socket is closed or changed to a different
+socket, all connections are immediately dropped.
+.Pp
+In
+.Fl auto
+mode, when an outgoing packet is detected,
+.Nm
+will perform the dialing action (chat script) and try to connect
+with the peer.
+In
+.Fl ddial
+mode, the dialing action is performed any time the line is found
+to be down.
+If the connect fails, the default behaviour is to wait 30 seconds
+and then attempt to connect when another outgoing packet is detected.
+This behaviour can be changed using the
+.Dq set redial
+command:
+.Pp
+.No set redial Ar secs Ns Xo
+.Oo + Ns Ar inc Ns
+.Op - Ns Ar max Ns
+.Oc Ns Op . Ns Ar next
+.Op Ar attempts
+.Xc
+.Pp
+.Bl -tag -width attempts -compact
+.It Ar secs
+is the number of seconds to wait before attempting
+to connect again.
+If the argument is the literal string
+.Sq Li random ,
+the delay period is a random value between 1 and 30 seconds inclusive.
+.It Ar inc
+is the number of seconds that
+.Ar secs
+should be incremented each time a new dial attempt is made.
+The timeout reverts to
+.Ar secs
+only after a successful connection is established.
+The default value for
+.Ar inc
+is zero.
+.It Ar max
+is the maximum number of times
+.Nm
+should increment
+.Ar secs .
+The default value for
+.Ar max
+is 10.
+.It Ar next
+is the number of seconds to wait before attempting
+to dial the next number in a list of numbers (see the
+.Dq set phone
+command).
+The default is 3 seconds.
+Again, if the argument is the literal string
+.Sq Li random ,
+the delay period is a random value between 1 and 30 seconds.
+.It Ar attempts
+is the maximum number of times to try to connect for each outgoing packet
+that triggers a dial.
+The previous value is unchanged if this parameter is omitted.
+If a value of zero is specified for
+.Ar attempts ,
+.Nm
+will keep trying until a connection is made.
+.El
+.Pp
+So, for example:
+.Bd -literal -offset indent
+set redial 10.3 4
+.Ed
+.Pp
+will attempt to connect 4 times for each outgoing packet that causes
+a dial attempt with a 3 second delay between each number and a 10 second
+delay after all numbers have been tried.
+If multiple phone numbers
+are specified, the total number of attempts is still 4 (it does not
+attempt each number 4 times).
+.Pp
+Alternatively,
+.Pp
+.Bd -literal -offset indent
+set redial 10+10-5.3 20
+.Ed
+.Pp
+tells
+.Nm
+to attempt to connect 20 times.
+After the first attempt,
+.Nm
+pauses for 10 seconds.
+After the next attempt it pauses for 20 seconds
+and so on until after the sixth attempt it pauses for 1 minute.
+The next 14 pauses will also have a duration of one minute.
+If
+.Nm
+connects, disconnects and fails to connect again, the timeout starts again
+at 10 seconds.
+.Pp
+Modifying the dial delay is very useful when running
+.Nm
+in
+.Fl auto
+mode on both ends of the link.
+If each end has the same timeout,
+both ends wind up calling each other at the same time if the link
+drops and both ends have packets queued.
+At some locations, the serial link may not be reliable, and carrier
+may be lost at inappropriate times.
+It is possible to have
+.Nm
+redial should carrier be unexpectedly lost during a session.
+.Bd -literal -offset indent
+set reconnect timeout ntries
+.Ed
+.Pp
+This command tells
+.Nm
+to re-establish the connection
+.Ar ntries
+times on loss of carrier with a pause of
+.Ar timeout
+seconds before each try.
+For example,
+.Bd -literal -offset indent
+set reconnect 3 5
+.Ed
+.Pp
+tells
+.Nm
+that on an unexpected loss of carrier, it should wait
+.Ar 3
+seconds before attempting to reconnect.
+This may happen up to
+.Ar 5
+times before
+.Nm
+gives up.
+The default value of ntries is zero (no reconnect).
+Care should be taken with this option.
+If the local timeout is slightly
+longer than the remote timeout, the reconnect feature will always be
+triggered (up to the given number of times) after the remote side
+times out and hangs up.
+NOTE: In this context, losing too many LQRs constitutes a loss of
+carrier and will trigger a reconnect.
+If the
+.Fl background
+flag is specified, all phone numbers are dialed at most once until
+a connection is made.
+The next number redial period specified with the
+.Dq set redial
+command is honoured, as is the reconnect tries value.
+If your redial
+value is less than the number of phone numbers specified, not all
+the specified numbers will be tried.
+To terminate the program, type
+.Bd -literal -offset indent
+PPP ON awfulhak> close
+ppp ON awfulhak> quit all
+.Ed
+.Pp
+A simple
+.Dq quit
+command will terminate the
+.Xr pppctl 8
+or
+.Xr telnet 1
+connection but not the
+.Nm
+program itself.
+You must use
+.Dq quit all
+to terminate
+.Nm
+as well.
+.Sh RECEIVING INCOMING PPP CONNECTIONS (Method 1)
+To handle an incoming
+.Em PPP
+connection request, follow these steps:
+.Bl -enum
+.It
+Make sure the modem and (optionally)
+.Pa /etc/rc.serial
+is configured correctly.
+.Bl -bullet -compact
+.It
+Use Hardware Handshake (CTS/RTS) for flow control.
+.It
+Modem should be set to NO echo back (ATE0) and NO results string (ATQ1).
+.El
+.Pp
+.It
+Edit
+.Pa /etc/ttys
+to enable a
+.Xr getty 8
+on the port where the modem is attached.
+For example:
+.Pp
+.Dl ttyd1 Qo /usr/libexec/getty std.38400 Qc dialup on secure
+.Pp
+Don't forget to send a
+.Dv HUP
+signal to the
+.Xr init 8
+process to start the
+.Xr getty 8 :
+.Pp
+.Dl # kill -HUP 1
+.Pp
+It is usually also necessary to train your modem to the same DTR speed
+as the getty:
+.Bd -literal -offset indent
+# ppp
+ppp ON awfulhak> set device /dev/cuaa1
+ppp ON awfulhak> set speed 38400
+ppp ON awfulhak> term
+deflink: Entering terminal mode on /dev/cuaa1
+Type `~?' for help
+at
+OK
+at
+OK
+atz
+OK
+at
+OK
+~.
+ppp ON awfulhak> quit
+.Ed
+.It
+Create a
+.Pa /usr/local/bin/ppplogin
+file with the following contents:
+.Bd -literal -offset indent
+#! /bin/sh
+exec /usr/sbin/ppp -direct incoming
+.Ed
+.Pp
+Direct mode
+.Pq Fl direct
+lets
+.Nm
+work with stdin and stdout.
+You can also use
+.Xr pppctl 8
+to connect to a configured diagnostic port, in the same manner as with
+client-side
+.Nm .
+.Pp
+Here, the
+.Ar incoming
+section must be set up in
+.Pa /etc/ppp/ppp.conf .
+.Pp
+Make sure that the
+.Ar incoming
+section contains the
+.Dq allow users
+command as appropriate.
+.It
+Prepare an account for the incoming user.
+.Bd -literal
+ppp:xxxx:66:66:PPP Login User:/home/ppp:/usr/local/bin/ppplogin
+.Ed
+.Pp
+Refer to the manual entries for
+.Xr adduser 8
+and
+.Xr vipw 8
+for details.
+.It
+Support for IPCP Domain Name Server and NetBIOS Name Server negotiation
+can be enabled using the
+.Dq accept dns
+and
+.Dq set nbns
+commands.
+Refer to their descriptions below.
+.El
+.Sh RECEIVING INCOMING PPP CONNECTIONS (Method 2)
+This method differs in that we use
+.Nm
+to authenticate the connection rather than
+.Xr login 1 :
+.Bl -enum
+.It
+Configure your default section in
+.Pa /etc/gettytab
+with automatic ppp recognition by specifying the
+.Dq pp
+capability:
+.Bd -literal
+default:\\
+	:pp=/usr/local/bin/ppplogin:\\
+	.....
+.Ed
+.It
+Configure your serial device(s), enable a
+.Xr getty 8
+and create
+.Pa /usr/local/bin/ppplogin
+as in the first three steps for method 1 above.
+.It
+Add either
+.Dq enable chap
+or
+.Dq enable pap
+(or both)
+to
+.Pa /etc/ppp/ppp.conf
+under the
+.Sq incoming
+label (or whatever label
+.Pa ppplogin
+uses).
+.It
+Create an entry in
+.Pa /etc/ppp/ppp.secret
+for each incoming user:
+.Bd -literal
+Pfred<TAB>xxxx
+Pgeorge<TAB>yyyy
+.Ed
+.El
+.Pp
+Now, as soon as
+.Xr getty 8
+detects a ppp connection (by recognising the HDLC frame headers), it runs
+.Dq /usr/local/bin/ppplogin .
+.Pp
+It is
+.Em VITAL
+that either PAP or CHAP are enabled as above.
+If they are not, you are
+allowing anybody to establish a ppp session with your machine
+.Em without
+a password, opening yourself up to all sorts of potential attacks.
+.Sh AUTHENTICATING INCOMING CONNECTIONS
+Normally, the receiver of a connection requires that the peer
+authenticates itself.
+This may be done using
+.Xr login 1 ,
+but alternatively, you can use PAP or CHAP.
+CHAP is the more secure of the two, but some clients may not support it.
+Once you decide which you wish to use, add the command
+.Sq enable chap
+or
+.Sq enable pap
+to the relevant section of
+.Pa ppp.conf .
+.Pp
+You must then configure the
+.Pa /etc/ppp/ppp.secret
+file.
+This file contains one line per possible client, each line
+containing up to five fields:
+.Pp
+.Ar name Ar key Oo
+.Ar hisaddr Op Ar label Op Ar callback-number
+.Oc
+.Pp
+The
+.Ar name
+and
+.Ar key
+specify the client username and password.
+If
+.Ar key
+is
+.Dq \&*
+and PAP is being used,
+.Nm
+will look up the password database
+.Pq Xr passwd 5
+when authenticating.
+If the client does not offer a suitable response based on any
+.Ar name Ns No / Ns Ar key
+combination in
+.Pa ppp.secret ,
+authentication fails.
+.Pp
+If authentication is successful,
+.Ar hisaddr
+(if specified)
+is used when negotiating IP numbers.
+See the
+.Dq set ifaddr
+command for details.
+.Pp
+If authentication is successful and
+.Ar label
+is specified, the current system label is changed to match the given
+.Ar label .
+This will change the subsequent parsing of the
+.Pa ppp.linkup
+and
+.Pa ppp.linkdown
+files.
+.Pp
+If authentication is successful and
+.Ar callback-number
+is specified and
+.Dq set callback
+has been used in
+.Pa ppp.conf ,
+the client will be called back on the given number.
+If CBCP is being used,
+.Ar callback-number
+may also contain a list of numbers or a
+.Dq \&* ,
+as if passed to the
+.Dq set cbcp
+command.
+The value will be used in
+.Nm Ns No 's
+subsequent CBCP phase.
+.Sh PPP OVER TCP and UDP (a.k.a Tunnelling)
+Instead of running
+.Nm
+over a serial link, it is possible to
+use a TCP connection instead by specifying the host, port and protocol as the
+device:
+.Pp
+.Dl set device ui-gate:6669/tcp
+.Pp
+Instead of opening a serial device,
+.Nm
+will open a TCP connection to the given machine on the given
+socket.
+It should be noted however that
+.Nm
+doesn't use the telnet protocol and will be unable to negotiate
+with a telnet server.
+You should set up a port for receiving this
+.Em PPP
+connection on the receiving machine (ui-gate).
+This is done by first updating
+.Pa /etc/services
+to name the service:
+.Pp
+.Dl ppp-in 6669/tcp # Incoming PPP connections over TCP
+.Pp
+and updating
+.Pa /etc/inetd.conf
+to tell
+.Xr inetd 8
+how to deal with incoming connections on that port:
+.Pp
+.Dl ppp-in stream tcp nowait root /usr/sbin/ppp ppp -direct ppp-in
+.Pp
+Don't forget to send a
+.Dv HUP
+signal to
+.Xr inetd 8
+after you've updated
+.Pa /etc/inetd.conf .
+Here, we use a label named
+.Dq ppp-in .
+The entry in
+.Pa /etc/ppp/ppp.conf
+on ui-gate (the receiver) should contain the following:
+.Bd -literal -offset indent
+ppp-in:
+ set timeout 0
+ set ifaddr 10.0.4.1 10.0.4.2
+.Ed
+.Pp
+and the entry in
+.Pa /etc/ppp/ppp.linkup
+should contain:
+.Bd -literal -offset indent
+ppp-in:
+ add 10.0.1.0/24 HISADDR
+.Ed
+.Pp
+It is necessary to put the
+.Dq add
+command in
+.Pa ppp.linkup
+to ensure that the route is only added after
+.Nm
+has negotiated and assigned addresses to its interface.
+.Pp
+You may also want to enable PAP or CHAP for security.
+To enable PAP, add the following line:
+.Bd -literal -offset indent
+ enable PAP
+.Ed
+.Pp
+You'll also need to create the following entry in
+.Pa /etc/ppp/ppp.secret :
+.Bd -literal -offset indent
+MyAuthName MyAuthPasswd
+.Ed
+.Pp
+If
+.Ar MyAuthPasswd
+is a
+.Dq * ,
+the password is looked up in the
+.Xr passwd 5
+database.
+.Pp
+The entry in
+.Pa /etc/ppp/ppp.conf
+on awfulhak (the initiator) should contain the following:
+.Bd -literal -offset indent
+ui-gate:
+ set escape 0xff
+ set device ui-gate:ppp-in/tcp
+ set dial
+ set timeout 30
+ set log Phase Chat Connect hdlc LCP IPCP IPV6CP CCP tun
+ set ifaddr 10.0.4.2 10.0.4.1
+.Ed
+.Pp
+with the route setup in
+.Pa /etc/ppp/ppp.linkup :
+.Bd -literal -offset indent
+ui-gate:
+ add 10.0.2.0/24 HISADDR
+.Ed
+.Pp
+Again, if you're enabling PAP, you'll also need this in the
+.Pa /etc/ppp/ppp.conf
+profile:
+.Bd -literal -offset indent
+ set authname MyAuthName
+ set authkey MyAuthKey
+.Ed
+.Pp
+We're assigning the address of 10.0.4.1 to ui-gate, and the address
+10.0.4.2 to awfulhak.
+To open the connection, just type
+.Pp
+.Dl awfulhak # ppp -background ui-gate
+.Pp
+The result will be an additional "route" on awfulhak to the
+10.0.2.0/24 network via the TCP connection, and an additional
+"route" on ui-gate to the 10.0.1.0/24 network.
+The networks are effectively bridged - the underlying TCP
+connection may be across a public network (such as the
+Internet), and the
+.Em PPP
+traffic is conceptually encapsulated
+(although not packet by packet) inside the TCP stream between
+the two gateways.
+.Pp
+The major disadvantage of this mechanism is that there are two
+"guaranteed delivery" mechanisms in place - the underlying TCP
+stream and whatever protocol is used over the
+.Em PPP
+link - probably TCP again.
+If packets are lost, both levels will
+get in each others way trying to negotiate sending of the missing
+packet.
+.Pp
+To avoid this overhead, it is also possible to do all this using
+UDP instead of TCP as the transport by simply changing the protocol
+from "tcp" to "udp".
+When using UDP as a transport,
+.Nm
+will operate in synchronous mode.
+This is another gain as the incoming
+data does not have to be rearranged into packets.
+.Pp
+Care should be taken when adding a default route through a tunneled
+setup like this.
+It is quite common for the default route
+(added in
+.Pa /etc/ppp/ppp.linkup )
+to end up routing the link's TCP connection through the tunnel,
+effectively garrotting the connection.
+To avoid this, make sure you add a static route for the benefit of
+the link:
+.Bd -literal -offset indent
+ui-gate:
+ set escape 0xff
+ set device ui-gate:ppp-in/tcp
+ add ui-gate x.x.x.x
+ .....
+.Ed
+.Pp
+where
+.Dq x.x.x.x
+is the IP number that your route to
+.Dq ui-gate
+would normally use.
+.Pp
+When routing your connection accross a public network such as the Internet,
+it is preferable to encrypt the data.
+This can be done with the help of the MPPE protocol, although currently this
+means that you will not be able to also compress the traffic as MPPE is
+implemented as a compression layer (thank Microsoft for this).
+To enable MPPE encryption, add the following lines to
+.Pa /etc/ppp/ppp.conf
+on the server:
+.Bd -literal -offset indent
+  enable MSCHAPv2
+  disable deflate pred1
+  deny deflate pred1
+.Ed
+.Pp
+ensuring that you've put the requisite entry in
+.Pa /etc/ppp/ppp.secret
+(MSCHAPv2 is challenge based, so
+.Xr passwd 5
+cannot be used)
+.Pp
+MSCHAPv2 and MPPE are accepted by default, so the client end should work
+without any additional changes (although ensure you have
+.Dq set authname
+and
+.Dq set authkey
+in your profile).
+.Sh NETWORK ADDRESS TRANSLATION (PACKET ALIASING)
+The
+.Fl nat
+command line option enables network address translation (a.k.a. packet
+aliasing).
+This allows the
+.Nm
+host to act as a masquerading gateway for other computers over
+a local area network.
+Outgoing IP packets are NAT'd so that they appear to come from the
+.Nm
+host, and incoming packets are de-NAT'd so that they are routed
+to the correct machine on the local area network.
+NAT allows computers on private, unregistered subnets to have Internet
+access, although they are invisible from the outside world.
+In general, correct
+.Nm
+operation should first be verified with network address translation disabled.
+Then, the
+.Fl nat
+option should be switched on, and network applications (web browser,
+.Xr telnet 1 ,
+.Xr ftp 1 ,
+.Xr ping 8 ,
+.Xr traceroute 8 )
+should be checked on the
+.Nm
+host.
+Finally, the same or similar applications should be checked on other
+computers in the LAN.
+If network applications work correctly on the
+.Nm
+host, but not on other machines in the LAN, then the masquerading
+software is working properly, but the host is either not forwarding
+or possibly receiving IP packets.
+Check that IP forwarding is enabled in
+.Pa /etc/rc.conf
+and that other machines have designated the
+.Nm
+host as the gateway for the LAN.
+.Sh PACKET FILTERING
+This implementation supports packet filtering.
+There are four kinds of
+filters: the
+.Em in
+filter, the
+.Em out
+filter, the
+.Em dial
+filter and the
+.Em alive
+filter.
+Here are the basics:
+.Bl -bullet
+.It
+A filter definition has the following syntax:
+.Pp
+set filter
+.Ar name
+.Ar rule-no
+.Ar action
+.Op !\&
+.Oo
+.Op host
+.Ar src_addr Ns Op / Ns Ar width
+.Op Ar dst_addr Ns Op / Ns Ar width
+.Oc
+.Ar [ proto Op src Ar cmp port
+.Op dst Ar cmp port
+.Op estab
+.Op syn
+.Op finrst
+.Op timeout Ar secs ]
+.Bl -enum
+.It
+.Ar Name
+should be one of
+.Sq in ,
+.Sq out ,
+.Sq dial
+or
+.Sq alive .
+.It
+.Ar Rule-no
+is a numeric value between
+.Sq 0
+and
+.Sq 39
+specifying the rule number.
+Rules are specified in numeric order according to
+.Ar rule-no ,
+but only if rule
+.Sq 0
+is defined.
+.It
+.Ar Action
+may be specified as
+.Sq permit
+or
+.Sq deny ,
+in which case, if a given packet matches the rule, the associated action
+is taken immediately.
+.Ar Action
+can also be specified as
+.Sq clear
+to clear the action associated with that particular rule, or as a new
+rule number greater than the current rule.
+In this case, if a given
+packet matches the current rule, the packet will next be matched against
+the new rule number (rather than the next rule number).
+.Pp
+The
+.Ar action
+may optionally be followed with an exclamation mark
+.Pq Dq !\& ,
+telling
+.Nm
+to reverse the sense of the following match.
+.It
+.Op Ar src_addr Ns Op / Ns Ar width
+and
+.Op Ar dst_addr Ns Op / Ns Ar width
+are the source and destination IP number specifications.
+If
+.Op / Ns Ar width
+is specified, it gives the number of relevant netmask bits,
+allowing the specification of an address range.
+.Pp
+Either
+.Ar src_addr
+or
+.Ar dst_addr
+may be given the values
+.Dv MYADDR ,
+.Dv HISADDR ,
+.Dv MYADDR6
+or
+.Dv HISADDR6
+(refer to the description of the
+.Dq bg
+command for a description of these values).
+When these values are used,
+the filters will be updated any time the values change.
+This is similar to the behaviour of the
+.Dq add
+command below.
+.It
+.Ar Proto
+may be any protocol from
+.Xr protocols 5 .
+.It
+.Ar Cmp
+is one of
+.Sq \&lt ,
+.Sq \&eq
+or
+.Sq \&gt ,
+meaning less-than, equal and greater-than respectively.
+.Ar Port
+can be specified as a numeric port or by service name from
+.Pa /etc/services .
+.It
+The
+.Sq estab ,
+.Sq syn ,
+and
+.Sq finrst
+flags are only allowed when
+.Ar proto
+is set to
+.Sq tcp ,
+and represent the TH_ACK, TH_SYN and TH_FIN or TH_RST TCP flags respectively.
+.It
+The timeout value adjusts the current idle timeout to at least
+.Ar secs
+seconds.
+If a timeout is given in the alive filter as well as in the in/out
+filter, the in/out value is used.
+If no timeout is given, the default timeout (set using
+.Ic set timeout
+and defaulting to 180 seconds) is used.
+.El
+.Pp
+.It
+Each filter can hold up to 40 rules, starting from rule 0.
+The entire rule set is not effective until rule 0 is defined,
+i.e., the default is to allow everything through.
+.It
+If no rule in a defined set of rules matches a packet, that packet will
+be discarded (blocked).
+If there are no rules in a given filter, the packet will be permitted.
+.It
+It's possible to filter based on the payload of UDP frames where those
+frames contain a
+.Em PROTO_IP
+.Em PPP
+frame header.
+See the
+.Ar filter-decapsulation
+option below for further details.
+.It
+Use
+.Dq set filter Ar name No -1
+to flush all rules.
+.El
+.Pp
+See
+.Pa /usr/share/examples/ppp/ppp.conf.sample .
+.Sh SETTING THE IDLE TIMER
+To check/set the idle timer, use the
+.Dq show bundle
+and
+.Dq set timeout
+commands:
+.Bd -literal -offset indent
+ppp ON awfulhak> set timeout 600
+.Ed
+.Pp
+The timeout period is measured in seconds, the default value for which
+is 180 seconds
+(or 3 min).
+To disable the idle timer function, use the command
+.Bd -literal -offset indent
+ppp ON awfulhak> set timeout 0
+.Ed
+.Pp
+In
+.Fl ddial
+and
+.Fl dedicated
+modes, the idle timeout is ignored.
+In
+.Fl auto
+mode, when the idle timeout causes the
+.Em PPP
+session to be
+closed, the
+.Nm
+program itself remains running.
+Another trigger packet will cause it to attempt to re-establish the link.
+.Sh PREDICTOR-1 and DEFLATE COMPRESSION
+.Nm
+supports both Predictor type 1 and deflate compression.
+By default,
+.Nm
+will attempt to use (or be willing to accept) both compression protocols
+when the peer agrees
+(or requests them).
+The deflate protocol is preferred by
+.Nm .
+Refer to the
+.Dq disable
+and
+.Dq deny
+commands if you wish to disable this functionality.
+.Pp
+It is possible to use a different compression algorithm in each direction
+by using only one of
+.Dq disable deflate
+and
+.Dq deny deflate
+(assuming that the peer supports both algorithms).
+.Pp
+By default, when negotiating DEFLATE,
+.Nm
+will use a window size of 15.
+Refer to the
+.Dq set deflate
+command if you wish to change this behaviour.
+.Pp
+A special algorithm called DEFLATE24 is also available, and is disabled
+and denied by default.
+This is exactly the same as DEFLATE except that
+it uses CCP ID 24 to negotiate.
+This allows
+.Nm
+to successfully negotiate DEFLATE with
+.Nm pppd
+version 2.3.*.
+.Sh CONTROLLING IP ADDRESS
+For IPv4,
+.Nm
+uses IPCP to negotiate IP addresses.
+Each side of the connection
+specifies the IP address that it's willing to use, and if the requested
+IP address is acceptable then
+.Nm
+returns an ACK to the requester.
+Otherwise,
+.Nm
+returns NAK to suggest that the peer use a different IP address.
+When
+both sides of the connection agree to accept the received request (and
+send an ACK), IPCP is set to the open state and a network level connection
+is established.
+To control this IPCP behaviour, this implementation has the
+.Dq set ifaddr
+command for defining the local and remote IP address:
+.Bd -ragged -offset indent
+.No set ifaddr Oo Ar src_addr Ns
+.Op / Ns Ar \&nn
+.Oo Ar dst_addr Ns Op / Ns Ar \&nn
+.Oo Ar netmask
+.Op Ar trigger_addr
+.Oc
+.Oc
+.Oc
+.Ed
+.Pp
+where,
+.Sq src_addr
+is the IP address that the local side is willing to use,
+.Sq dst_addr
+is the IP address which the remote side should use and
+.Sq netmask
+is the netmask that should be used.
+.Sq Src_addr
+defaults to the current
+.Xr hostname 1 ,
+.Sq dst_addr
+defaults to 0.0.0.0, and
+.Sq netmask
+defaults to whatever mask is appropriate for
+.Sq src_addr .
+It is only possible to make
+.Sq netmask
+smaller than the default.
+The usual value is 255.255.255.255, as
+most kernels ignore the netmask of a POINTOPOINT interface.
+.Pp
+Some incorrect
+.Em PPP
+implementations require that the peer negotiates a specific IP
+address instead of
+.Sq src_addr .
+If this is the case,
+.Sq trigger_addr
+may be used to specify this IP number.
+This will not affect the
+routing table unless the other side agrees with this proposed number.
+.Bd -literal -offset indent
+set ifaddr 192.244.177.38 192.244.177.2 255.255.255.255 0.0.0.0
+.Ed
+.Pp
+The above specification means:
+.Pp
+.Bl -bullet -compact
+.It
+I will first suggest that my IP address should be 0.0.0.0, but I
+will only accept an address of 192.244.177.38.
+.It
+I strongly insist that the peer uses 192.244.177.2 as his own
+address and won't permit the use of any IP address but 192.244.177.2.
+When the peer requests another IP address, I will always suggest that
+it uses 192.244.177.2.
+.It
+The routing table entry will have a netmask of 0xffffffff.
+.El
+.Pp
+This is all fine when each side has a pre-determined IP address, however
+it is often the case that one side is acting as a server which controls
+all IP addresses and the other side should go along with it.
+In order to allow more flexible behaviour, the
+.Dq set ifaddr
+command allows the user to specify IP addresses more loosely:
+.Pp
+.Dl set ifaddr 192.244.177.38/24 192.244.177.2/20
+.Pp
+A number followed by a slash
+.Pq Dq /
+represents the number of bits significant in the IP address.
+The above example means:
+.Pp
+.Bl -bullet -compact
+.It
+I'd like to use 192.244.177.38 as my address if it is possible, but I'll
+also accept any IP address between 192.244.177.0 and 192.244.177.255.
+.It
+I'd like to make him use 192.244.177.2 as his own address, but I'll also
+permit him to use any IP address between 192.244.176.0 and
+192.244.191.255.
+.It
+As you may have already noticed, 192.244.177.2 is equivalent to saying
+192.244.177.2/32.
+.It
+As an exception, 0 is equivalent to 0.0.0.0/0, meaning that I have no
+preferred IP address and will obey the remote peers selection.
+When using zero, no routing table entries will be made until a connection
+is established.
+.It
+192.244.177.2/0 means that I'll accept/permit any IP address but I'll
+suggest that 192.244.177.2 be used first.
+.El
+.Pp
+When negotiating IPv6 addresses, no control is given to the user.
+IPV6CP negotiation is fully automatic.
+.Sh CONNECTING WITH YOUR INTERNET SERVICE PROVIDER
+The following steps should be taken when connecting to your ISP:
+.Bl -enum
+.It
+Describe your providers phone number(s) in the dial script using the
+.Dq set phone
+command.
+This command allows you to set multiple phone numbers for
+dialing and redialing separated by either a pipe
+.Pq Dq \&|
+or a colon
+.Pq Dq \&: :
+.Bd -ragged -offset indent
+.No set phone Ar telno Ns Xo
+.Oo \&| Ns Ar backupnumber
+.Oc Ns ... Ns Oo : Ns Ar nextnumber
+.Oc Ns ...
+.Xc
+.Ed
+.Pp
+Numbers after the first in a pipe-separated list are only used if the
+previous number was used in a failed dial or login script.
+Numbers
+separated by a colon are used sequentially, irrespective of what happened
+as a result of using the previous number.
+For example:
+.Bd -literal -offset indent
+set phone "1234567|2345678:3456789|4567890"
+.Ed
+.Pp
+Here, the 1234567 number is attempted.
+If the dial or login script fails,
+the 2345678 number is used next time, but *only* if the dial or login script
+fails.
+On the dial after this, the 3456789 number is used.
+The 4567890
+number is only used if the dial or login script using the 3456789 fails.
+If the login script of the 2345678 number fails, the next number is still the
+3456789 number.
+As many pipes and colons can be used as are necessary
+(although a given site would usually prefer to use either the pipe or the
+colon, but not both).
+The next number redial timeout is used between all numbers.
+When the end of the list is reached, the normal redial period is
+used before starting at the beginning again.
+The selected phone number is substituted for the \\\\T string in the
+.Dq set dial
+command (see below).
+.It
+Set up your redial requirements using
+.Dq set redial .
+For example, if you have a bad telephone line or your provider is
+usually engaged (not so common these days), you may want to specify
+the following:
+.Bd -literal -offset indent
+set redial 10 4
+.Ed
+.Pp
+This says that up to 4 phone calls should be attempted with a pause of 10
+seconds before dialing the first number again.
+.It
+Describe your login procedure using the
+.Dq set dial
+and
+.Dq set login
+commands.
+The
+.Dq set dial
+command is used to talk to your modem and establish a link with your
+ISP, for example:
+.Bd -literal -offset indent
+set dial "ABORT BUSY ABORT NO\\\\sCARRIER TIMEOUT 4 \\"\\" \e
+  ATZ OK-ATZ-OK ATDT\\\\T TIMEOUT 60 CONNECT"
+.Ed
+.Pp
+This modem "chat" string means:
+.Bl -bullet
+.It
+Abort if the string "BUSY" or "NO CARRIER" are received.
+.It
+Set the timeout to 4 seconds.
+.It
+Expect nothing.
+.It
+Send ATZ.
+.It
+Expect OK.
+If that's not received within the 4 second timeout, send ATZ
+and expect OK.
+.It
+Send ATDTxxxxxxx where xxxxxxx is the next number in the phone list from
+above.
+.It
+Set the timeout to 60.
+.It
+Wait for the CONNECT string.
+.El
+.Pp
+Once the connection is established, the login script is executed.
+This script is written in the same style as the dial script, but care should
+be taken to avoid having your password logged:
+.Bd -literal -offset indent
+set authkey MySecret
+set login "TIMEOUT 15 login:-\\\\r-login: awfulhak \e
+  word: \\\\P ocol: PPP HELLO"
+.Ed
+.Pp
+This login "chat" string means:
+.Bl -bullet
+.It
+Set the timeout to 15 seconds.
+.It
+Expect "login:".
+If it's not received, send a carriage return and expect
+"login:" again.
+.It
+Send "awfulhak"
+.It
+Expect "word:" (the tail end of a "Password:" prompt).
+.It
+Send whatever our current
+.Ar authkey
+value is set to.
+.It
+Expect "ocol:" (the tail end of a "Protocol:" prompt).
+.It
+Send "PPP".
+.It
+Expect "HELLO".
+.El
+.Pp
+The
+.Dq set authkey
+command is logged specially.
+When
+.Ar command
+or
+.Ar chat
+logging is enabled, the actual password is not logged;
+.Sq ********
+is logged instead.
+.Pp
+Login scripts vary greatly between ISPs.
+If you're setting one up for the first time,
+.Em ENABLE CHAT LOGGING
+so that you can see if your script is behaving as you expect.
+.It
+Use
+.Dq set device
+and
+.Dq set speed
+to specify your serial line and speed, for example:
+.Bd -literal -offset indent
+set device /dev/cuaa0
+set speed 115200
+.Ed
+.Pp
+Cuaa0 is the first serial port on
+.Fx .
+If you're running
+.Nm
+on
+.Ox ,
+cua00 is the first.
+A speed of 115200 should be specified
+if you have a modem capable of bit rates of 28800 or more.
+In general, the serial speed should be about four times the modem speed.
+.It
+Use the
+.Dq set ifaddr
+command to {define} the IP address.
+.Bl -bullet
+.It
+If you know what IP address your provider uses, then use it as the remote
+address (dst_addr), otherwise choose something like 10.0.0.2/0 (see below).
+.It
+If your provider has assigned a particular IP address to you, then use
+it as your address (src_addr).
+.It
+If your provider assigns your address dynamically, choose a suitably
+unobtrusive and unspecific IP number as your address.
+10.0.0.1/0 would be appropriate.
+The bit after the / specifies how many bits of the
+address you consider to be important, so if you wanted to insist on
+something in the class C network 1.2.3.0, you could specify 1.2.3.1/24.
+.It
+If you find that your ISP accepts the first IP number that you suggest,
+specify third and forth arguments of
+.Dq 0.0.0.0 .
+This will force your ISP to assign a number.
+(The third argument will
+be ignored as it is less restrictive than the default mask for your
+.Sq src_addr ) .
+.El
+.Pp
+An example for a connection where you don't know your IP number or your
+ISPs IP number would be:
+.Bd -literal -offset indent
+set ifaddr 10.0.0.1/0 10.0.0.2/0 0.0.0.0 0.0.0.0
+.Ed
+.Pp
+.It
+In most cases, your ISP will also be your default router.
+If this is the case, add the line
+.Bd -literal -offset indent
+add default HISADDR
+.Ed
+.Pp
+to
+.Pa /etc/ppp/ppp.conf
+(or to
+.Pa /etc/ppp/ppp.linkup
+for setups that don't use
+.Fl auto
+mode).
+.Pp
+This tells
+.Nm
+to add a default route to whatever the peer address is
+(10.0.0.2 in this example).
+This route is
+.Sq sticky ,
+meaning that should the value of
+.Dv HISADDR
+change, the route will be updated accordingly.
+.It
+If your provider requests that you use PAP/CHAP authentication methods, add
+the next lines to your
+.Pa /etc/ppp/ppp.conf
+file:
+.Bd -literal -offset indent
+set authname MyName
+set authkey MyPassword
+.Ed
+.Pp
+Both are accepted by default, so
+.Nm
+will provide whatever your ISP requires.
+.Pp
+It should be noted that a login script is rarely (if ever) required
+when PAP or CHAP are in use.
+.It
+Ask your ISP to authenticate your nameserver address(es) with the line
+.Bd -literal -offset indent
+enable dns
+.Ed
+.Pp
+Do
+.Em NOT
+do this if you are running a local DNS unless you also either use
+.Dq resolv readonly
+or have
+.Dq resolv restore
+in
+.Pa /etc/ppp/ppp.linkdown ,
+as
+.Nm
+will simply circumvent its use by entering some nameserver lines in
+.Pa /etc/resolv.conf .
+.El
+.Pp
+Please refer to
+.Pa /usr/share/examples/ppp/ppp.conf.sample
+and
+.Pa /usr/share/examples/ppp/ppp.linkup.sample
+for some real examples.
+The pmdemand label should be appropriate for most ISPs.
+.Sh LOGGING FACILITY
+.Nm
+is able to generate the following log info either via
+.Xr syslog 3
+or directly to the screen:
+.Pp
+.Bl -tag -width XXXXXXXXX -offset XXX -compact
+.It Li All
+Enable all logging facilities.
+This generates a lot of log.
+The most common use of 'all' is as a basis, where you remove some facilities
+after enabling 'all' ('debug' and 'timer' are usually best disabled.)
+.It Li Async
+Dump async level packet in hex.
+.It Li CBCP
+Generate CBCP (CallBack Control Protocol) logs.
+.It Li CCP
+Generate a CCP packet trace.
+.It Li Chat
+Generate
+.Sq dial ,

+.It Li Error
+Output to both the terminal device
+and the log file using syslogs
+.Dv LOG_ERROR .
+.It Li Alert
+Output to the log file using
+.Dv LOG_ALERT .
+.El
+.Pp
+The
+.Dq set log
+command allows you to set the logging output level.
+Multiple levels can be specified on a single command line.
+The default is equivalent to
+.Dq set log Phase .
+.Pp
+It is also possible to log directly to the screen.
+The syntax is the same except that the word
+.Dq local
+should immediately follow
+.Dq set log .
+The default is
+.Dq set log local
+(i.e., only the un-maskable warning, error and alert output).
+.Pp
+If The first argument to
+.Dq set log Op local
+begins with a
+.Sq +
+or a

+PPP ON awfulhak> show log
+Log:   Phase TCP/IP Warning Error Alert
+Local: Command Warning Error Alert
+.Ed
+.Pp
+Log messages of level Warning, Error and Alert are not controllable
+using
+.Dq set log Op local .
+.Pp
+The
+.Ar Warning
+level is special in that it will not be logged if it can be displayed
+locally.
+.Sh SIGNAL HANDLING
+.Nm
+deals with the following signals:
+.Bl -tag -width "USR2"
+.It INT
+Receipt of this signal causes the termination of the current connection
+(if any).
+This will cause
+.Nm
+to exit unless it is in
+.Fl auto
+or
+.Fl ddial
+mode.
+.It HUP, TERM & QUIT
+These signals tell
+.Nm
+to exit.
+.It USR1
+This signal, tells
+.Nm
+to re-open any existing server socket, dropping all existing diagnostic
+connections.
+Sockets that couldn't previously be opened will be retried.
+.It USR2
+This signal, tells
+.Nm
+to close any existing server socket, dropping all existing diagnostic
+connections.
+.Dv SIGUSR1
+can still be used to re-open the socket.
+.El
+.Sh MULTI-LINK PPP
+If you wish to use more than one physical link to connect to a
+.Em PPP
+peer, that peer must also understand the
+.Em MULTI-LINK PPP
+protocol.
+Refer to RFC 1990 for specification details.
+.Pp
+The peer is identified using a combination of his
+.Dq endpoint discriminator
+and his
+.Dq authentication id .
+Either or both of these may be specified.
+It is recommended that
+at least one is specified, otherwise there is no way of ensuring that
+all links are actually connected to the same peer program, and some
+confusing lock-ups may result.
+Locally, these identification variables are specified using the
+.Dq set enddisc
+and
+.Dq set authname
+commands.
+The
+.Sq authname
+(and
+.Sq authkey )
+must be agreed in advance with the peer.
+.Pp
+Multi-link capabilities are enabled using the
+.Dq set mrru
+command (set maximum reconstructed receive unit).
+Once multi-link is enabled,
+.Nm
+will attempt to negotiate a multi-link connection with the peer.
+.Pp
+By default, only one
+.Sq link
+is available
+(called
+.Sq deflink ) .
+To create more links, the
+.Dq clone
+command is used.
+This command will clone existing links, where all
+characteristics are the same except:
+.Bl -enum
+.It
+The new link has its own name as specified on the
+.Dq clone
+command line.
+.It
+The new link is an
+.Sq interactive
+link.
+Its mode may subsequently be changed using the
+.Dq set mode
+command.
+.It
+The new link is in a
+.Sq closed
+state.
+.El
+.Pp
+A summary of all available links can be seen using the
+.Dq show links
+command.
+.Pp
+Once a new link has been created, command usage varies.
+All link specific commands must be prefixed with the
+.Dq link Ar name
+command, specifying on which link the command is to be applied.
+When only a single link is available,
+.Nm
+is smart enough not to require the
+.Dq link Ar name
+prefix.
+.Pp
+Some commands can still be used without specifying a link - resulting
+in an operation at the
+.Sq bundle
+level.
+For example, once two or more links are available, the command
+.Dq show ccp
+will show CCP configuration and statistics at the multi-link level, and
+.Dq link deflink show ccp
+will show the same information at the
+.Dq deflink
+link level.
+.Pp
+Armed with this information, the following configuration might be used:
+.Pp
+.Bd -literal -offset indent
+mp:
+ set timeout 0
+ set log phase chat

+.Pp
+When

+has negotiated
+.Em MULTI-LINK
+mode with the peer, it creates a local domain socket in the
+.Pa /var/run
+directory.
+This socket is used to pass link information (including
+the actual link file descriptor) between different
+.Nm
+invocations.
+This facilitates
+.Nm Ns No 's
+ability to be run from a
+.Xr getty 8
+or directly from
+.Pa /etc/gettydefs
+(using the
+.Sq pp=
+capability), without needing to have initial control of the serial
+line.
+Once
+.Nm
+negotiates multi-link mode, it will pass its open link to any
+already running process.
+If there is no already running process,
+.Nm
+will act as the master, creating the socket and listening for new
+connections.
+.Sh PPP COMMAND LIST
+This section lists the available commands and their effect.
+They are usable either from an interactive
+.Nm
+session, from a configuration file or from a
+.Xr pppctl 8
+or
+.Xr telnet 1
+session.
+.Bl -tag -width 2n
+.It accept|deny|enable|disable Ar option....
+These directives tell
+.Nm
+how to negotiate the initial connection with the peer.
+Each
+.Dq option
+has a default of either accept or deny and enable or disable.
+.Dq Accept
+means that the option will be ACK'd if the peer asks for it.
+.Dq Deny
+means that the option will be NAK'd if the peer asks for it.
+.Dq Enable
+means that the option will be requested by us.
+.Dq Disable
+means that the option will not be requested by us.
+.Pp
+.Dq Option
+may be one of the following:
+.Bl -tag -width 2n
+.It acfcomp
+Default: Enabled and Accepted.
+ACFComp stands for Address and Control Field Compression.
+Non LCP packets will usually have an address
+field of 0xff (the All-Stations address) and a control field of
+0x03 (the Unnumbered Information command).
+If this option is
+negotiated, these two bytes are simply not sent, thus minimising
+traffic.
+.Pp
+See
+.Pa rfc1662
+for details.
+.It chap Ns Op \&05
+Default: Disabled and Accepted.
+CHAP stands for Challenge Handshake Authentication Protocol.
+Only one of CHAP and PAP (below) may be negotiated.
+With CHAP, the authenticator sends a "challenge" message to its peer.
+The peer uses a one-way hash function to encrypt the
+challenge and sends the result back.
+The authenticator does the same, and compares the results.
+The advantage of this mechanism is that no
+passwords are sent across the connection.
+A challenge is made when the connection is first made.
+Subsequent challenges may occur.
+If you want to have your peer authenticate itself, you must
+.Dq enable chap .
+in
+.Pa /etc/ppp/ppp.conf ,
+and have an entry in
+.Pa /etc/ppp/ppp.secret
+for the peer.
+.Pp
+When using CHAP as the client, you need only specify
+.Dq AuthName
+and
+.Dq AuthKey
+in
+.Pa /etc/ppp/ppp.conf .
+CHAP is accepted by default.
+Some
+.Em PPP
+implementations use "MS-CHAP" rather than MD5 when encrypting the
+challenge.
+MS-CHAP is a combination of MD4 and DES.
+If
+.Nm
+was built on a machine with DES libraries available, it will respond
+to MS-CHAP authentication requests, but will never request them.
+.It deflate
+Default: Enabled and Accepted.
+This option decides if deflate
+compression will be used by the Compression Control Protocol (CCP).
+This is the same algorithm as used by the
+.Xr gzip 1
+program.
+Note: There is a problem negotiating
+.Ar deflate
+capabilities with
+.Xr pppd 8
+- a
+.Em PPP
+implementation available under many operating systems.
+.Nm pppd
+(version 2.3.1) incorrectly attempts to negotiate
+.Ar deflate
+compression using type
+.Em 24
+as the CCP configuration type rather than type
+.Em 26
+as specified in
+.Pa rfc1979 .
+Type
+.Ar 24
+is actually specified as
+.Dq PPP Magna-link Variable Resource Compression
+in
+.Pa rfc1975 Ns !
+.Nm
+is capable of negotiating with
+.Nm pppd ,
+but only if
+.Dq deflate24
+is
+.Ar enable Ns No d
+and
+.Ar accept Ns No ed .
+.It deflate24
+Default: Disabled and Denied.
+This is a variance of the
+.Ar deflate
+option, allowing negotiation with the
+.Xr pppd 8
+program.
+Refer to the
+.Ar deflate
+section above for details.
+It is disabled by default as it violates
+.Pa rfc1975 .
+.It dns
+Default: Disabled and Denied.
+This option allows DNS negotiation.
+.Pp
+If
+.Dq enable Ns No d,
+.Nm
+will request that the peer confirms the entries in
+.Pa /etc/resolv.conf .
+If the peer NAKs our request (suggesting new IP numbers),
+.Pa /etc/resolv.conf
+is updated and another request is sent to confirm the new entries.
+.Pp
+If
+.Dq accept Ns No ed,
+.Nm
+will answer any DNS queries requested by the peer rather than rejecting
+them.
+The answer is taken from
+.Pa /etc/resolv.conf
+unless the
+.Dq set dns
+command is used as an override.
+.It enddisc
+Default: Enabled and Accepted.
+This option allows control over whether we
+negotiate an endpoint discriminator.
+We only send our discriminator if
+.Dq set enddisc
+is used and
+.Ar enddisc
+is enabled.
+We reject the peers discriminator if
+.Ar enddisc
+is denied.
+.It LANMan|chap80lm
+Default: Disabled and Accepted.
+The use of this authentication protocol
+is discouraged as it partially violates the authentication protocol by
+implementing two different mechanisms (LANMan & NT) under the guise of
+a single CHAP type (0x80).
+.Dq LANMan
+uses a simple DES encryption mechanism and is the least secure of the
+CHAP alternatives (although is still more secure than PAP).
+.Pp
+Refer to the
+.Dq MSChap
+description below for more details.
+.It lqr
+Default: Disabled and Accepted.
+This option decides if Link Quality Requests will be sent or accepted.
+LQR is a protocol that allows
+.Nm
+to determine that the link is down without relying on the modems
+carrier detect.
+When LQR is enabled,
+.Nm
+sends the
+.Em QUALPROTO
+option (see
+.Dq set lqrperiod
+below) as part of the LCP request.
+If the peer agrees, both sides will
+exchange LQR packets at the agreed frequency, allowing detailed link
+quality monitoring by enabling LQM logging.
+If the peer doesn't agree,
+.Nm
+will send ECHO LQR requests instead.
+These packets pass no information of interest, but they
+.Em MUST
+be replied to by the peer.
+.Pp
+Whether using LQR or ECHO LQR,
+.Nm
+will abruptly drop the connection if 5 unacknowledged packets have been
+sent rather than sending a 6th.
+A message is logged at the
+.Em PHASE
+level, and any appropriate
+.Dq reconnect
+values are honoured as if the peer were responsible for dropping the
+connection.
+.It mppe
+Default: Enabled and Accepted.
+This is Microsoft Point to Point Encryption scheme.
+MPPE key size can be
+40-, 56- and 128-bits.
+Refer to
+.Dq set mppe
+command.
+.It MSChapV2|chap81
+Default: Disabled and Accepted.
+It is very similar to standard CHAP (type 0x05)
+except that it issues challenges of a fixed 16 bytes in length and uses a
+combination of MD4, SHA-1 and DES to encrypt the challenge rather than using the
+standard MD5 mechanism.
+.It MSChap|chap80nt
+Default: Disabled and Accepted.
+The use of this authentication protocol
+is discouraged as it partially violates the authentication protocol by
+implementing two different mechanisms (LANMan & NT) under the guise of
+a single CHAP type (0x80).
+It is very similar to standard CHAP (type 0x05)
+except that it issues challenges of a fixed 8 bytes in length and uses a
+combination of MD4 and DES to encrypt the challenge rather than using the
+standard MD5 mechanism.
+CHAP type 0x80 for LANMan is also supported - see
+.Dq enable LANMan
+for details.
+.Pp
+Because both
+.Dq LANMan
+and
+.Dq NT
+use CHAP type 0x80, when acting as authenticator with both
+.Dq enable Ns No d ,
+.Nm
+will rechallenge the peer up to three times if it responds using the wrong
+one of the two protocols.
+This gives the peer a chance to attempt using both protocols.
+.Pp
+Conversely, when
+.Nm
+acts as the authenticatee with both protocols
+.Dq accept Ns No ed ,
+the protocols are used alternately in response to challenges.
+.Pp
+Note: If only LANMan is enabled,
+.Xr pppd 8
+(version 2.3.5) misbehaves when acting as authenticatee.
+It provides both
+the NT and the LANMan answers, but also suggests that only the NT answer
+should be used.
+.It pap
+Default: Disabled and Accepted.
+PAP stands for Password Authentication Protocol.
+Only one of PAP and CHAP (above) may be negotiated.
+With PAP, the ID and Password are sent repeatedly to the peer until
+authentication is acknowledged or the connection is terminated.
+This is a rather poor security mechanism.
+It is only performed when the connection is first established.
+If you want to have your peer authenticate itself, you must
+.Dq enable pap .
+in
+.Pa /etc/ppp/ppp.conf ,
+and have an entry in
+.Pa /etc/ppp/ppp.secret
+for the peer (although see the
+.Dq passwdauth
+and
+.Dq set radius
+options below).
+.Pp
+When using PAP as the client, you need only specify
+.Dq AuthName
+and
+.Dq AuthKey
+in
+.Pa /etc/ppp/ppp.conf .
+PAP is accepted by default.
+.It pred1
+Default: Enabled and Accepted.
+This option decides if Predictor 1
+compression will be used by the Compression Control Protocol (CCP).
+.It protocomp
+Default: Enabled and Accepted.
+This option is used to negotiate
+PFC (Protocol Field Compression), a mechanism where the protocol
+field number is reduced to one octet rather than two.
+.It shortseq
+Default: Enabled and Accepted.
+This option determines if
+.Nm
+will request and accept requests for short
+(12 bit)
+sequence numbers when negotiating multi-link mode.
+This is only applicable if our MRRU is set (thus enabling multi-link).
+.It vjcomp
+Default: Enabled and Accepted.
+This option determines if Van Jacobson header compression will be used.
+.El
+.Pp
+The following options are not actually negotiated with the peer.
+Therefore, accepting or denying them makes no sense.
+.Bl -tag -width 2n
+.It filter-decapsulation
+Default: Disabled.
+When this option is enabled,
+.Nm
+will examine UDP frames to see if they actually contain a
+.Em PPP
+frame as their payload.
+If this is the case, all filters will operate on the payload rather
+than the actual packet.
+.Pp
+This is useful if you want to send PPPoUDP traffic over a
+.Em PPP
+link, but want that link to do smart things with the real data rather than
+the UDP wrapper.
+.Pp
+The UDP frame payload must not be compressed in any way, otherwise
+.Nm
+will not be able to interpret it.
+It's therefore recommended that you
+.Ic disable vj pred1 deflate
+and
+.Ic deny vj pred1 deflate
+in the configuration for the
+.Nm
+invocation with the udp link.
+.It idcheck
+Default: Enabled.
+When
+.Nm
+exchanges low-level LCP, CCP and IPCP configuration traffic, the
+.Em Identifier
+field of any replies is expected to be the same as that of the request.
+By default,
+.Nm
+drops any reply packets that do not contain the expected identifier
+field, reporting the fact at the respective log level.
+If
+.Ar idcheck
+is disabled,
+.Nm
+will ignore the identifier field.
+.It iface-alias
+Default: Enabled if
+.Fl nat
+is specified.
+This option simply tells
+.Nm
+to add new interface addresses to the interface rather than replacing them.
+The option can only be enabled if network address translation is enabled
+.Pq Dq nat enable yes .
+.Pp
+With this option enabled,
+.Nm
+will pass traffic for old interface addresses through the NAT
+ifdef({LOCALNAT},{engine,},{engine
+(see
+.Xr libalias 3 ) ,})
+resulting in the ability (in
+.Fl auto
+mode) to properly connect the process that caused the PPP link to
+come up in the first place.
+.Pp
+Disabling NAT with
+.Dq nat enable no
+will also disable
+.Sq iface-alias .
+.It ipcp
+Default: Enabled.
+This option allows
+.Nm
+to attempt to negotiate IP control protocol capabilities and if
+successful to exchange IP datagrams with the peer.
+.It ipv6cp
+Default: Enabled.
+This option allows
+.Nm
+to attempt to negotiate IPv6 control protocol capabilities and if
+successful to exchange IPv6 datagrams with the peer.
+.It keep-session
+Default: Disabled.
+When
+.Nm
+runs as a Multi-link server, a different
+.Nm
+instance initially receives each connection.
+After determining that
+the link belongs to an already existing bundle (controlled by another
+.Nm
+invocation),
+.Nm
+will transfer the link to that process.
+.Pp
+If the link is a tty device or if this option is enabled,
+.Nm
+will not exit, but will change its process name to
+.Dq session owner
+and wait for the controlling
+.Nm
+to finish with the link and deliver a signal back to the idle process.
+This prevents the confusion that results from
+.Nm Ns No 's
+parent considering the link resource available again.
+.Pp
+For tty devices that have entries in
+.Pa /etc/ttys ,
+this is necessary to prevent another
+.Xr getty 8
+from being started, and for program links such as
+.Xr sshd 8 ,
+it prevents
+.Xr sshd 8
+from exiting due to the death of its child.
+As
+.Nm
+cannot determine its parents requirements (except for the tty case), this
+option must be enabled manually depending on the circumstances.
+.It loopback
+Default: Enabled.
+When
+.Ar loopback
+is enabled,
+.Nm
+will automatically loop back packets being sent
+out with a destination address equal to that of the
+.Em PPP
+interface.
+If disabled,
+.Nm
+will send the packet, probably resulting in an ICMP redirect from
+the other end.
+It is convenient to have this option enabled when
+the interface is also the default route as it avoids the necessity
+of a loopback route.
+.It passwdauth
+Default: Disabled.
+Enabling this option will tell the PAP authentication
+code to use the password database (see
+.Xr passwd 5 )
+to authenticate the caller if they cannot be found in the
+.Pa /etc/ppp/ppp.secret
+file.
+.Pa /etc/ppp/ppp.secret
+is always checked first.
+If you wish to use passwords from
+.Xr passwd 5 ,
+but also to specify an IP number or label for a given client, use
+.Dq \&*
+as the client password in
+.Pa /etc/ppp/ppp.secret .
+.It proxy
+Default: Disabled.
+Enabling this option will tell
+.Nm
+to proxy ARP for the peer.
+This means that
+.Nm
+will make an entry in the ARP table using
+.Dv HISADDR
+and the
+.Dv MAC
+address of the local network in which
+.Dv HISADDR
+appears.
+This allows other machines connecteed to the LAN to talk to
+the peer as if the peer itself was connected to the LAN.
+The proxy entry cannot be made unless
+.Dv HISADDR
+is an address from a LAN.
+.It proxyall
+Default: Disabled.
+Enabling this will tell
+.Nm
+to add proxy arp entries for every IP address in all class C or
+smaller subnets routed via the tun interface.
+.Pp
+Proxy arp entries are only made for sticky routes that are added
+using the
+.Dq add
+command.
+No proxy arp entries are made for the interface address itself
+(as created by the
+.Dq set ifaddr
+command).
+.It sroutes
+Default: Enabled.
+When the
+.Dq add
+command is used with the
+.Dv HISADDR ,
+.Dv MYADDR ,
+.Dv HISADDR6
+or
+.Dv MYADDR6
+values, entries are stored in the
+.Sq sticky route
+list.
+Each time these variables change, this list is re-applied to the routing table.
+.Pp
+Disabling this option will prevent the re-application of sticky routes,
+although the
+.Sq stick route
+list will still be maintained.
+.It Op tcp Ns Xo
+.No mssfixup
+.Xc
+Default: Enabled.
+This option tells
+.Nm
+to adjust TCP SYN packets so that the maximum receive segment
+size is not greater than the amount allowed by the interface MTU.
+.It throughput
+Default: Enabled.
+This option tells
+.Nm
+to gather throughput statistics.
+Input and output is sampled over
+a rolling 5 second window, and current, best and total figures are retained.
+This data is output when the relevant
+.Em PPP
+layer shuts down, and is also available using the
+.Dq show
+command.
+Throughput statistics are available at the
+.Dq IPCP
+and
+.Dq physical
+levels.
+.It utmp
+Default: Enabled.
+Normally, when a user is authenticated using PAP or CHAP, and when
+.Nm
+is running in
+.Fl direct
+mode, an entry is made in the utmp and wtmp files for that user.
+Disabling this option will tell
+.Nm
+not to make any utmp or wtmp entries.
+This is usually only necessary if
+you require the user to both login and authenticate themselves.
+.El
+.Pp
+.It add Ns Xo
+.Op !\&
+.Ar dest Ns Op / Ns Ar nn
+.Op Ar mask
+.Op Ar gateway
+.Xc
+.Ar Dest

+Routes that contain the
+.Dq HISADDR ,
+.Dq MYADDR ,
+.Dq HISADDR6 ,

+This facility may be disabled using
+.Dq disable sroutes .
+.It allow Ar command Op Ar args
+This command controls access to
+.Nm
+and its configuration files.
+It is possible to allow user-level access,
+depending on the configuration file label and on the mode that
+.Nm
+is being run in.
+For example, you may wish to configure
+.Nm
+so that only user
+.Sq fred

+If this command is used, all of the listed users are allowed access to
+the section in which the
+.Dq allow users
+command is found.
+The
+.Sq default
+section is always checked first (even though it is only ever automatically
+loaded at startup).
+.Dq allow users
+commands are cumulative in a given section, but users allowed in any given
+section override users allowed in the default section, so it's possible to
+allow users access to everything except a given label by specifying default
+users in the

+.Pp
+If nat is enabled on your system (it may be omitted at compile time),

+.It nat target Op Ar address
+Set the given target address or clear it if no address is given.
+The target address is used

+.It open Op lcp|ccp|ipcp
+This is the opposite of the

+All closed links are immediately brought up apart from second and subsequent
+.Ar demand-dial
+links - these will come up based on the
+.Dq set autoload
+command that has been used.
+.Pp
+If the
+.Dq lcp
+argument is used while the LCP layer is already open, LCP will be
+renegotiated.
+This allows various LCP options to be changed, after which
+.Dq open lcp
+can be used to put them into effect.
+After renegotiating LCP,
+any agreed authentication will also take place.
+.Pp
+If the
+.Dq ccp
+argument is used, the relevant compression layer is opened.
+Again, if it is already open, it will be renegotiated.
+.Pp
+If the
+.Dq ipcp
+argument is used, the link will be brought up as normal, but if
+IPCP is already open, it will be renegotiated and the network
+interface will be reconfigured.
+.Pp
+It is probably not good practice to re-open the PPP state machines
+like this as it's possible that the peer will not behave correctly.
+It
+.Em is
+however useful as a way of forcing the CCP or VJ dictionaries to be reset.
+.It passwd Ar pass
+Specify the password required for access to the full
+.Nm

+This password is required when connecting to the diagnostic port (see the
+.Dq set server
+command).
+.Ar Pass
+is specified on the
+.Dq set server

+.It quit|bye Op all
+If

+Otherwise, if the user
+is connected to a diagnostic socket, the connection is simply dropped.
+.Pp
+If the
+.Ar all
+argument is given,
+.Nm
+will exit despite the source of the command after closing all existing
+connections.
+.It remove|rm
+This command removes the given link.
+It is only really useful in multi-link mode.
+A link must be in the
+.Dv CLOSED
+state before it is removed.
+.It rename|mv Ar name
+This command renames the given link to
+.Ar name .
+It will fail if
+.Ar name
+is already used by another link.
+.Pp
+The default link name is
+.Sq deflink .
+Renaming it to
+.Sq modem ,
+.Sq cuaa0
+or
+.Sq USR
+may make the log file more readable.
+.It resolv Ar command
+This command controls
+.Nm Ns No 's
+manipulation of the
+.Xr resolv.conf 5
+file.
+When

+.Bl -tag -width readonly
+.It Em readonly
+Treat

+macros.
+This is the opposite of the
+.Dq resolv writable
+command.
+.It Em reload
+Reload
+.Pa /etc/resolv.conf
+into memory.
+This may be necessary if for example a DHCP client overwrote
+.Pa /etc/resolv.conf .
+.It Em restore
+Replace
+.Pa /etc/resolv.conf
+with the version originally read at startup or with the last
+.Dq resolv reload
+command.
+This is sometimes a useful command to put in the
+.Pa /etc/ppp/ppp.linkdown
+file.
+.It Em rewrite
+Rewrite the
+.Pa /etc/resolv.conf
+file.
+This command will work even if the
+.Dq resolv readonly
+command has been used.
+It may be useful as a command in the
+.Pa /etc/ppp/ppp.linkup
+file if you wish to defer updating
+.Pa /etc/resolv.conf
+until after other commands have finished.
+.It Em writable
+Allow
+.Nm
+to update
+.Pa /etc/resolv.conf
+if
+.Dq dns
+is enabled and
+.Nm
+successfully negotiates a DNS.
+This is the opposite of the
+.Dq resolv readonly
+command.
+.El
+.It save
+This option is not (yet) implemented.
+.It sendident
+This command tells
+.Nm
+to identify itself to the peer.
+The link must be in LCP state or higher.
+If no identity has been set (via the
+.Ic ident
+command),
+.Ic sendident
+will fail.
+.Pp
+When an identity has been set,
+.Nm
+will automatically identify itself when it sends or receives a configure
+reject, when negotiation fails or when LCP reaches the opened state.
+.Pp
+Received identification packets are logged to the LCP log (see
+.Ic set log
+for details) and are never responded to.
+.It set Ns Xo
+.Op up
+.Ar var value
+.Xc
+This option allows the setting of any of the following variables:
+.Bl -tag -width 2n
+.It set accmap Ar hex-value
+ACCMap stands for Asynchronous Control Character Map.
+This is always
+negotiated with the peer, and defaults to a value of 00000000 in hex.
+This protocol is required to defeat hardware that depends on passing
+certain characters from end to end (such as XON/XOFF etc).
+.Pp
+For the XON/XOFF scenario, use
+.Dq set accmap 000a0000 .
+.It set Op auth Ns Xo
+.No key Ar value
+.Xc
+This sets the authentication key (or password) used in client mode
+PAP or CHAP negotiation to the given value.
+It also specifies the
+password to be used in the dial or login scripts in place of the
+.Sq \eP
+sequence, preventing the actual password from being logged.
+If
+.Ar command
+or
+.Ar chat
+logging is in effect,
+.Ar value
+is logged as
+.Sq ********
+for security reasons.
+.Pp
+If the first character of
+.Ar value
+is an exclamation mark
+.Pq Dq !\& ,
+.Nm
+treats the remainder of the string as a program that must be executed
+to determine the
+.Dq authname
+and
+.Dq authkey
+values.
+.Pp
+If the
+.Dq !\&
+is doubled up
+(to

+it is treated as a single literal
+.Dq !\& ,
+otherwise, ignoring the
+.Dq !\& ,
+.Ar value
+is parsed as a program to execute in the same was as the
+.Dq !bg
+command above, substituting special names in the same manner.
+Once executed,
+.Nm
+will feed the program three lines of input, each terminated by a newline
+character:

+to be sent with the CHAP response.
+.It
+The
+.Dq authkey ,
+which is encrypted with the challenge and request id, the answer being sent
+in the CHAP response packet.
+.El
+.Pp
+When configuring
+.Nm
+in this manner, it's expected that the host challenge is a series of ASCII
+digits or characters.
+An encryption device or Secure ID card is usually
+required to calculate the secret appropriate for the given challenge.
+.It set authname Ar id
+This sets the authentication id used in client mode PAP or CHAP negotiation.
+.Pp
+If used in
+.Fl direct
+mode with CHAP enabled,
+.Ar id
+is used in the initial authentication challenge and should normally be set to
+the local machine name.
+.It set autoload Xo
+.Ar min-percent max-percent period
+.Xc
+These settings apply only in multi-link mode and default to zero, zero and
+five respectively.
+When more than one
+.Ar demand-dial
+(also known as
+.Fl auto )
+mode link is available, only the first link is made active when
+.Nm
+first reads data from the tun device.
+The next
+.Ar demand-dial
+link will be opened only when the current bundle throughput is at least
+.Ar max-percent
+percent of the total bundle bandwidth for
+.Ar period
+seconds.
+When the current bundle throughput decreases to
+.Ar min-percent
+percent or less of the total bundle bandwidth for
+.Ar period
+seconds, a
+.Ar demand-dial
+link will be brought down as long as it's not the last active link.
+.Pp
+Bundle throughput is measured as the maximum of inbound and outbound
+traffic.
+.Pp
+The default values cause
+.Ar demand-dial
+links to simply come up one at a time.
+.Pp
+Certain devices cannot determine their physical bandwidth, so it
+is sometimes necessary to use the
+.Dq set bandwidth
+command (described below) to make
+.Dq set autoload
+work correctly.
+.It set bandwidth Ar value
+This command sets the connection bandwidth in bits per second.
+.Ar value

+See also the

+command below.
+Refer to
+.Xr chat 8
+and to the example configuration files for details of the chat script
+format.
+It is possible to specify some special
+.Sq values
+in your chat script as follows:
+.Bl -tag -width 2n
+.It Li \ec
+When used as the last character in a
+.Sq send
+string, this indicates that a newline should not be appended.
+.It Li \ed
+When the chat script encounters this sequence, it delays two seconds.
+.It Li \ep
+When the chat script encounters this sequence, it delays for one quarter of
+a second.
+.It Li \en
+This is replaced with a newline character.
+.It Li \er
+This is replaced with a carriage return character.
+.It Li \es
+This is replaced with a space character.
+.It Li \et
+This is replaced with a tab character.
+.It Li \eT
+This is replaced by the current phone number (see
+.Dq set phone
+below).
+.It Li \eP
+This is replaced by the current
+.Ar authkey
+value (see
+.Dq set authkey
+above).
+.It Li \eU
+This is replaced by the current
+.Ar authname
+value (see
+.Dq set authname
+above).
+.El
+.Pp
+Note that two parsers will examine these escape sequences, so in order to
+have the
+.Sq chat parser
+see the escape character, it is necessary to escape it from the
+.Sq command parser .
+This means that in practice you should use two escapes, for example:
+.Bd -literal -offset indent
+set dial "... ATDT\\\\T CONNECT"
+.Ed
+.Pp
+It is also possible to execute external commands from the chat script.
+To do this, the first character of the expect or send string is an
+exclamation mark
+.Pq Dq !\& .
+If a literal exclamation mark is required, double it up to
+.Dq !!\&
+and it will be treated as a single literal
+.Dq !\& .
+When the command is executed, standard input and standard output are
+directed to the open device (see the
+.Dq set device
+command), and standard error is read by
+.Nm
+and substituted as the expect or send string.
+If
+.Nm
+is running in interactive mode, file descriptor 3 is attached to
+.Pa /dev/tty .
+.Pp
+For example (wrapped for readability):
+.Bd -literal -offset indent
+set login "TIMEOUT 5 \\"\\" \\"\\" login:--login: ppp \e
+word: ppp \\"!sh \\\\-c \\\\\\"echo \\\\-n label: >&2\\\\\\"\\" \e
+\\"!/bin/echo in\\" HELLO"
+.Ed
+.Pp
+would result in the following chat sequence (output using the
+.Sq set log local chat
+command before dialing):
+.Bd -literal -offset indent
+Dial attempt 1 of 1
+dial OK!
+Chat: Expecting:
+Chat: Sending:
+Chat: Expecting: login:--login:
+Chat: Wait for (5): login:
+Chat: Sending: ppp
+Chat: Expecting: word:
+Chat: Wait for (5): word:
+Chat: Sending: ppp
+Chat: Expecting: !sh \\-c "echo \\-n label: >&2"
+Chat: Exec: sh -c "echo -n label: >&2"
+Chat: Wait for (5): !sh \\-c "echo \\-n label: >&2" --> label:
+Chat: Exec: /bin/echo in
+Chat: Sending:
+Chat: Expecting: HELLO
+Chat: Wait for (5): HELLO
+login OK!
+.Ed
+.Pp
+Note (again) the use of the escape character, allowing many levels of
+nesting.
+Here, there are four parsers at work.
+The first parses the original line, reading it as three arguments.
+The second parses the third argument, reading it as 11 arguments.
+At this point, it is
+important that the
+.Dq \&-
+signs are escaped, otherwise this parser will see them as constituting
+an expect-send-expect sequence.
+When the
+.Dq !\&
+character is seen, the execution parser reads the first command as three
+arguments, and then
+.Xr sh 1
+itself expands the argument after the
+.Fl c .
+As we wish to send the output back to the modem, in the first example
+we redirect our output to file descriptor 2 (stderr) so that
+.Nm
+itself sends and logs it, and in the second example, we just output to stdout,
+which is attached directly to the modem.
+.Pp
+This, of course means that it is possible to execute an entirely external
+.Dq chat
+command rather than using the internal one.
+See
+.Xr chat 8
+for a good alternative.
+.Pp
+The external command that is executed is subjected to the same special
+word expansions as the
+.Dq !bg
+command.
+.It set enddisc Op label|IP|MAC|magic|psn value
+This command sets our local endpoint discriminator.
+If set prior to LCP negotiation, and if no
+.Dq disable enddisc
+command has been used,
+.Nm
+will send the information to the peer using the LCP endpoint discriminator
+option.
+The following discriminators may be set:
+.Bl -tag -width indent
+.It Li label
+The current label is used.
+.It Li IP
+Our local IP number is used.
+As LCP is negotiated prior to IPCP, it is
+possible that the IPCP layer will subsequently change this value.
+If
+it does, the endpoint discriminator stays at the old value unless manually
+reset.
+.It Li MAC
+This is similar to the
+.Ar IP
+option above, except that the MAC address associated with the local IP
+number is used.
+If the local IP number is not resident on any Ethernet
+interface, the command will fail.
+.Pp
+As the local IP number defaults to whatever the machine host name is,
+.Dq set enddisc mac
+is usually done prior to any
+.Dq set ifaddr
+commands.
+.It Li magic
+A 20 digit random number is used.
+Care should be taken when using magic numbers as restarting
+.Nm
+or creating a link using a different
+.Nm
+invocation will also use a different magic number and will therefore not
+be recognised by the peer as belonging to the same bundle.
+This makes it unsuitable for
+.Fl direct
+connections.
+.It Li psn Ar value
+The given
+.Ar value
+is used.
+.Ar Value
+should be set to an absolute public switched network number with the
+country code first.
+.El
+.Pp
+If no arguments are given, the endpoint discriminator is reset.
+.It set escape Ar value...
+This option is similar to the
+.Dq set accmap
+option above.
+It allows the user to specify a set of characters that will be
+.Sq escaped

+to dial when in
+.Fl auto

+The
+.Em in
+filter specifies packets that are allowed to travel
+into the machine and the
+.Em out
+filter specifies packets that are allowed out of the machine.
+.Pp
+Filtering is done prior to any IP alterations that might be done by the
+NAT engine on outgoing packets and after any IP alterations that might
+be done by the NAT engine on incoming packets.
+By default all empty filter sets allow all packets to pass.
+Rules are processed in order according to
+.Ar rule-no
+(unless skipped by specifying a rule number as the
+.Ar action ) .
+Up to 40 rules may be given for each set.
+If a packet doesn't match
+any of the rules in a given set, it is discarded.
+In the case of
+.Em in
+and
+.Em out
+filters, this means that the packet is dropped.
+In the case of
+.Em alive
+filters it means that the packet will not reset the idle timer (even if
+the
+.Ar in Ns No / Ns Ar out
+filter has a
+.Dq timeout
+value) and in the case of
+.Em dial
+filters it means that the packet will not trigger a dial.
+A packet failing to trigger a dial will be dropped rather than queued.
+Refer to the
+section on
+.Sx PACKET FILTERING
+above for further details.
+.It set hangup Ar chat-script
+This specifies the chat script that will be used to reset the device
+before it is closed.
+It should not normally be necessary, but can
+be used for devices that fail to reset themselves properly on close.
+.It set help|? Op Ar command

+.Oc Oc
+.Oc
+This command specifies the IP addresses that will be used during
+IPCP negotiation.
+Addresses are specified using the format
+.Pp
+.Dl a.b.c.d/nn
+.Pp
+Where
+.Dq a.b.c.d
+is the preferred IP, but
+.Ar nn
+specifies how many bits of the address we will insist on.

+.Pp
+will only negotiate
+.Dq 10.0.0.1
+as the local IP number, but may assign any of the given 10 IP
+numbers to the peer.
+If the peer requests one of these numbers,
+and that number is not already in use,
+.Nm
+will grant the peers request.
+This is useful if the peer wants
+to re-establish a link using the same IP number as was previously
+allocated (thus maintaining any existing tcp or udp connections).
+.Pp
+If the peer requests an IP number that's either outside
+of this range or is already in use,
+.Nm
+will suggest a random unused IP number from the range.
+.Pp
+If
+.Ar triggeraddr
+is specified, it is used in place of
+.Ar myaddr
+in the initial IPCP negotiation.
+However, only an address in the
+.Ar myaddr
+range will be accepted.
+This is useful when negotiating with some
+.Dv PPP
+implementations that will not assign an IP number unless their peer
+requests
+.Dq 0.0.0.0 .
+.Pp
+It should be noted that in
+.Fl auto
+mode,
+.Nm
+will configure the interface immediately upon reading the
+.Dq set ifaddr
+line in the config file.
+In any other mode, these values are just
+used for IPCP negotiations, and the interface isn't configured
+until the IPCP layer is up.
+.Pp
+Note that the

+(if PAP or CHAP are
+.Dq enabled ) .
+Refer to the
+.Sx AUTHENTICATING INCOMING CONNECTIONS
+section for details.
+.Pp
+In all cases, if the interface is already configured,
+.Nm
+will try to maintain the interface IP numbers so that any existing
+bound sockets will remain valid.
+.It set ifqueue Ar packets
+Set the maximum number of packets that
+.Nm
+will read from the tunnel interface while data cannot be sent to any of
+the available links.
+This queue limit is necessary to flow control outgoing data as the tunnel
+interface is likely to be far faster than the combined links available to
+.Nm .
+.Pp
+If
+.Ar packets
+is set to a value less than the number of links,
+.Nm
+will read up to that value regardless.
+This prevents any possible latency problems.

+for all FSMs is 3 seconds (which should suffice in most cases).
+.Pp
+If
+.Ar reqtries
+is specified, it tells
+.Nm
+how many configuration request attempts it should make while receiving
+no reply from the peer before giving up.
+The default is 5 attempts for
+CCP, LCP and IPCP and 3 attempts for PAP and CHAP.
+.Pp
+If
+.Ar trmtries
+is specified, it tells
+.Nm
+how many terminate requests should be sent before giving up waiting for the
+peers response.
+The default is 3 attempts.
+Authentication protocols are
+not terminated and it is therefore invalid to specify
+.Ar trmtries
+for PAP or CHAP.
+.Pp
+In order to avoid negotiations with the peer that will never converge,
+.Nm
+will only send at most 3 times the configured number of
+.Ar reqtries
+in any given negotiation session before giving up and closing that layer.

+This command allows the adjustment of the current log level.
+Refer to the Logging Facility section for further details.
+.It set login Ar chat-script

+.Ar chat-script
+compliments the dial-script.
+If both are specified, the login
+script will be executed after the dial script.
+Escape sequences available in the dial script are also available here.
+.It set logout Ar chat-script
+This specifies the chat script that will be used to logout
+before the hangup script is called.
+It should not normally be necessary.
+.It set lqrperiod Ar frequency
+This command sets the
+.Ar frequency
+in seconds at which
+.Em LQR

+.Em ECHO LQR
+packets are sent.
+The default is 30 seconds.
+You must also use the
+.Dq enable lqr
+command if you wish to send LQR requests to the peer.
+.It set mode Ar interactive|auto|ddial|background
+This command allows you to change the
+.Sq mode
+of the specified link.
+This is normally only useful in multi-link mode,
+but may also be used in uni-link mode.
+.Pp
+It is not possible to change a link that is
+.Sq direct
+or
+.Sq dedicated .
+.Pp
+Note: If you issue the command
+.Dq set mode auto ,
+and have network address translation enabled, it may be useful to
+.Dq enable iface-alias
+afterwards.
+This will allow
+.Nm
+to do the necessary address translations to enable the process that
+triggers the connection to connect once the link is up despite the
+peer assigning us a new (dynamic) IP address.
+.It set mppe Op 40|56|128|* Op stateless|stateful|*
+This option selects the encryption parameters used when negotiation
+MPPE.
+MPPE can be disabled entirely with the
+.Dq disable mppe
+command.
+If no arguments are given,
+.Nm
+will attempt to negotiate a stateful link with a 128 bit key, but
+will agree to whatever the peer requests (including no encryption
+at all).
+.Pp
+If any arguments are given,
+.Nm
+will
+.Em insist
+on using MPPE and will close the link if it's rejected by the peer (Note;
+this behaviour can be overridden by a configured RADIUS server).
+.Pp
+The first argument specifies the number of bits that
+.Nm
+should insist on during negotiations and the second specifies whether
+.Nm
+should insist on stateful or stateless mode.
+In stateless mode, the
+encryption dictionary is re-initialised with every packet according to
+an encryption key that is changed with every packet.
+In stateful mode,
+the encryption dictionary is re-initialised every 256 packets or after
+the loss of any data and the key is changed every 256 packets.
+Stateless mode is less efficient but is better for unreliable transport
+layers.
+.It set mrru Op Ar value
+Setting this option enables Multi-link PPP negotiations, also known as
+Multi-link Protocol or MP.
+There is no default MRRU (Maximum Reconstructed Receive Unit) value.
+If no argument is given, multi-link mode is disabled.
+.It set mru Xo
+.Op max Ns Op imum
+.Op Ar value
+.Xc
+The default MRU (Maximum Receive Unit) is 1500.
+If it is increased, the other side *may* increase its MTU.
+In theory there is no point in decreasing the MRU to below the default as the
+.Em PPP
+protocol says implementations *must* be able to accept packets of at
+least 1500 octets.
+.Pp
+If the
+.Dq maximum
+keyword is used,
+.Nm
+will refuse to negotiate a higher value.
+The maximum MRU can be set to 2048 at most.
+Setting a maximum of less than 1500 violates the
+.Em PPP
+rfc, but may sometimes be necessary.
+For example,
+.Em PPPoE
+imposes a maximum of 1492 due to hardware limitations.
+.Pp
+If no argument is given, 1500 is assumed.
+A value must be given when
+.Dq maximum
+is specified.
+.It set mtu Xo
+.Op max Ns Op imum
+.Op Ar value
+.Xc
+The default MTU is 1500.
+At negotiation time,
+.Nm
+will accept whatever MRU the peer requests (assuming it's
+not less than 296 bytes or greater than the assigned maximum).
+If the MTU is set,
+.Nm
+will not accept MRU values less than
+.Ar value .
+When negotiations are complete, the MTU is used when writing to the
+interface, even if the peer requested a higher value MRU.
+This can be useful for
+limiting your packet size (giving better bandwidth sharing at the expense
+of more header data).
+.Pp
+If the
+.Dq maximum
+keyword is used,
+.Nm
+will refuse to negotiate a higher value.
+The maximum MTU can be set to 2048 at most.
+.Pp
+If no
+.Ar value
+is given, 1500, or whatever the peer asks for is used.
+A value must be given when
+.Dq maximum
+is specified.
+.It set nbns Op Ar x.x.x.x Op Ar y.y.y.y
+This option allows the setting of the Microsoft NetBIOS name server
+values to be returned at the peers request.
+If no values are given,
+.Nm
+will reject any such requests.
+.It set openmode active|passive Op Ar delay
+By default,
+.Ar openmode
+is always
+.Ar active
+with a one second
+.Ar delay .
+That is,
+.Nm
+will always initiate LCP/IPCP/CCP negotiation one second after the line
+comes up.
+If you want to wait for the peer to initiate negotiations, you
+can use the value
+.Ar passive .
+If you want to initiate negotiations immediately or after more than one
+second, the appropriate
+.Ar delay
+may be specified here in seconds.
+.It set parity odd|even|none|mark
+This allows the line parity to be set.
+The default value is
+.Ar none .
+.It set phone Ar telno Ns Xo
+.Oo \&| Ns Ar backupnumber
+.Oc Ns ... Ns Oo : Ns Ar nextnumber
+.Oc Ns ...
+.Xc
+This allows the specification of the phone number to be used in

+Multiple phone numbers may be given separated either by a pipe
+.Pq Dq \&|
+or a colon
+.Pq Dq \&: .
+.Pp
+Numbers after the pipe are only dialed if the dial or login
+script for the previous number failed.
+.Pp
+Numbers after the colon are tried sequentially, irrespective of

+.Pp
+For example, a returned value of
+.Dq 1.2.3.4/24 0.0.0.0 1 2 -1 3 400
+would result in a routing table entry to the 1.2.3.0/24 network via
+.Dv HISADDR
+and a returned value of
+.Dq 0.0.0.0 0.0.0.0
+or
+.Dq default HISADDR
+would result in a default route to
+.Dv HISADDR .
+.Pp
+All RADIUS routes are applied after any sticky routes are applied, making
+RADIUS routes override configured routes.
+This also applies for RADIUS routes that don't {include} the
+.Dv MYADDR
+or
+.Dv HISADDR
+keywords.
+.Pp
+.It RAD_SESSION_TIMEOUT
+If supplied, the client connection is closed after the given number of

+authentication FAILURE text.
+.It RAD_MICROSOFT_MS_CHAP2_SUCCESS
+If this
+.Dv RAD_VENDOR_MICROSOFT

+.Dv RAD_VENDOR_MICROSOFT
+vendor specific attribute is supplied and has a value of 2 (Required),
+.Nm
+will insist that MPPE encryption is used (even if no
+.Dq set mppe
+configuration command has been given with arguments).
+If it is supplied with a value of 1 (Allowed), encryption is made optional
+(despite any
+.Dq set mppe
+configuration commands with arguments).
+.It RAD_MICROSOFT_MS_MPPE_ENCRYPTION_TYPES
+If this
+.Dv RAD_VENDOR_MICROSOFT
+vendor specific attribute is supplied, bits 1 and 2 are examined.
+If either or both are set, 40 bit and/or 128 bit (respectively) encryption
+options are set, overriding any given first argument to the
+.Dq set mppe
+command.
+Note, it is not currently possible for the RADIUS server to specify 56 bit
+encryption.
+.It RAD_MICROSOFT_MS_MPPE_RECV_KEY
+If this
+.Dv RAD_VENDOR_MICROSOFT
+vendor specific attribute is supplied, it's value is used as the master
+key for decryption of incoming data.  When clients are authenticated using
+MSCHAPv2, the RADIUS server MUST provide this attribute if inbound MPPE is
+to function.
+.It RAD_MICROSOFT_MS_MPPE_SEND_KEY
+If this
+.Dv RAD_VENDOR_MICROSOFT
+vendor specific attribute is supplied, it's value is used as the master
+key for encryption of outgoing data.  When clients are authenticated using
+MSCHAPv2, the RADIUS server MUST provide this attribute if outbound MPPE is
+to function.

+Values received from the RADIUS server may be viewed using
+.Dq show bundle .
+.It set reconnect Ar timeout ntries
+Should the line drop unexpectedly (due to loss of CD or LQR
+failure), a connection will be re-established after the given
+.Ar timeout .
+The line will be re-connected at most
+.Ar ntries
+times.
+.Ar Ntries
+defaults to zero.
+A value of
+.Ar random
+for
+.Ar timeout
+will result in a variable pause, somewhere between 1 and 30 seconds.
+.It set recvpipe Op Ar value
+This sets the routing table RECVPIPE value.
+The optimum value is just over twice the MTU value.
+If
+.Ar value
+is unspecified or zero, the default kernel controlled value is used.

+is taken before dialing each number.
+A pause of
+.Ar secs
+is taken before starting at the first number again.
+A literal value of
+.Dq Li random
+may be used here in place of
+.Ar secs
+and
+.Ar next ,
+causing a random delay of between 1 and 30 seconds.
+.Pp
+If
+.Ar inc
+is specified, its value is added onto
+.Ar secs
+each time
+.Nm
+tries a new number.
+.Ar secs
+will only be incremented at most
+.Ar max
+times.
+.Ar max
+defaults to 10.
+.Pp
+Note, the
+.Ar secs
+delay will be effective, even after
+.Ar attempts
+has been exceeded, so an immediate manual dial may appear to have
+done nothing.
+If an immediate dial is required, a
+.Dq !\&
+should immediately follow the
+.Dq open
+keyword.
+See the
+.Dq open
+description above for further details.
+.It set sendpipe Op Ar value
+This sets the routing table SENDPIPE value.
+The optimum value is just over twice the MTU value.

+.Op password Op Ar mask
+.Xc
+This command tells
+.Nm
+to listen on the given socket or
+.Sq diagnostic port
+for incoming command connections.
+.Pp
+The word
+.Dq none
+instructs
+.Nm
+to close any existing socket and clear the socket configuration.
+The word
+.Dq open
+instructs
+.Nm
+to attempt to re-open the port.
+The word
+.Dq closed
+instructs
+.Nm
+to close the open port.
+.Pp
+If you wish to specify a local domain socket,
+.Ar LocalName
+must be specified as an absolute file name, otherwise it is assumed
+to be the name or number of a TCP port.
+You may specify the octal umask to be used with a local domain socket.
+Refer to
+.Xr umask 2
+for umask details.
+Refer to
+.Xr services 5
+for details of how to translate TCP port names.
+.Pp
+You must also specify the password that must be entered by the client
+(using the
+.Dq passwd
+variable above) when connecting to this socket.
+If the password is
+specified as an empty string, no password is required for connecting clients.
+.Pp
+When specifying a local domain socket, the first
+.Dq %d
+sequence found in the socket name will be replaced with the current
+interface unit number.
+This is useful when you wish to use the same
+profile for more than one connection.
+.Pp
+In a similar manner TCP sockets may be prefixed with the
+.Dq +
+character, in which case the current interface unit number is added to
+the port number.
+.Pp
+When using
+.Nm
+with a server socket, the
+.Xr pppctl 8
+command is the preferred mechanism of communications.
+Currently,
+.Xr telnet 1
+can also be used, but link encryption may be implemented in the future, so
+.Xr telnet 1
+should be avoided.
+.Pp
+Note;
+.Dv SIGUSR1
+and
+.Dv SIGUSR2
+interact with the diagnostic socket.
+.It set speed Ar value
+This sets the speed of the serial device.
+If speed is specified as
+.Dq sync ,
+.Nm
+treats the device as a synchronous device.
+.Pp
+Certain device types will know whether they should be specified as
+synchronous or asynchronous.
+These devices will override incorrect
+settings and log a warning to this effect.
+.It set stopped Op Ar LCPseconds Op Ar CCPseconds
+If this option is set,
+.Nm
+will time out after the given FSM (Finite State Machine) has been in
+the stopped state for the given number of
+.Dq seconds .
+This option may be useful if the peer sends a terminate request,
+but never actually closes the connection despite our sending a terminate
+acknowledgement.
+This is also useful if you wish to
+.Dq set openmode passive
+and time out if the peer doesn't send a Configure Request within the
+given time.
+Use
+.Dq set log +lcp +ccp
+to make
+.Nm
+log the appropriate state transitions.
+.Pp
+The default value is zero, where
+.Nm
+doesn't time out in the stopped state.
+.Pp
+This value should not be set to less than the openmode delay (see
+.Dq set openmode
+above).
+.It set timeout Ar idleseconds Op Ar mintimeout
+This command allows the setting of the idle timer.
+Refer to the section titled
+.Sx SETTING THE IDLE TIMER
+for further details.
+.Pp
+If
+.Ar mintimeout
+is specified,
+.Nm
+will never idle out before the link has been up for at least that number
+of seconds.
+.It set urgent Xo
+.Op tcp|udp|none
+.Oo Op +|- Ns
+.Ar port
+.Oc No ...
+.Xc
+This command controls the ports that
+.Nm
+prioritizes when transmitting data.
+The default priority TCP ports
+are ports 21 (ftp control), 22 (ssh), 23 (telnet), 513 (login), 514 (shell),
+543 (klogin) and 544 (kshell).
+There are no priority UDP ports by default.
+See
+.Xr services 5
+for details.
+.Pp
+If neither
+.Dq tcp
+or
+.Dq udp
+are specified,
+.Dq tcp
+is assumed.
+.Pp
+If no
+.Ar port Ns No s
+are given, the priority port lists are cleared (although if
+.Dq tcp
+or
+.Dq udp
+is specified, only that list is cleared).
+If the first
+.Ar port
+argument is prefixed with a plus
+.Pq Dq \&+
+or a minus
+.Pq Dq \&- ,
+the current list is adjusted, otherwise the list is reassigned.
+.Ar port Ns No s
+prefixed with a plus or not prefixed at all are added to the list and
+.Ar port Ns No s
+prefixed with a minus are removed from the list.
+.Pp
+If
+.Dq none
+is specified, all priority port lists are disabled and even
+.Dv IPTOS_LOWDELAY
+packets are not prioritised.
+.It set vj slotcomp on|off
+This command tells
+.Nm
+whether it should attempt to negotiate VJ slot compression.
+By default, slot compression is turned
+.Ar on .
+.It set vj slots Ar nslots
+This command sets the initial number of slots that
+.Nm
+will try to negotiate with the peer when VJ compression is enabled (see the
+.Sq enable
+command above).
+It defaults to a value of 16.
+.Ar Nslots
+must be between

+and was submitted to
+.Fx 2.0.5
+by
+.An Atsushi Murai Aq amurai@spec.co.jp .
+.Pp
+It was substantially modified during 1997 by
+.An Brian Somers Aq brian@Awfulhak.org ,
+and was ported to
+.Ox
+in November that year
+(just after the 2.2 release).
+.Pp
+Most of the code was rewritten by

+ * the compressed packet.  The next two octets are the TCP checksum
+ * from the original datagram.  The next 0 to 15 octets are
+ * sequence number changes, one change per bit set in the header
+ * (there may be no changes and there are two special cases where
+ * the receiver implicitly knows what changed -- see below).
+ *
+ * There are 5 numbers which can change (they are always inserted
+ * in the following order): TCP urgent pointer, window,
+ * acknowlegement, sequence number and IP ID.  (The urgent pointer
+ * is different from the others in that its value is sent, not the
+ * change in value.)  Since typical use of SLIP links is biased
+ * toward small packets (see comments on MTU/MSS below), changes
+ * use a variable length coding with one octet for numbers in the
+ * range 1 - 255 and 3 octets (0, MSB, LSB) for numbers in the
+ * range 256 - 65535 or 0.  (If the change in sequence number or
+ * ack is more than 65535, an uncompressed packet is sent.)
+ */
+
+/*
+ * Packet types (must not conflict with IP protocol version)
+ *
+ * The top nibble of the first octet is the packet type.  There are
+ * three possible types: IP (not proto TCP or tcp with one of the
+ * control flags set); uncompressed TCP (a normal IP/TCP packet but
+ * with the 8-bit protocol field replaced by an 8-bit connection id --
+ * this type of packet syncs the sender & receiver); and compressed
+ * TCP (described above).
+ *
+ * LSB of 4-bit field is TCP "PUSH" bit (a worthless anachronism) and
+ * is logically part of the 4-bit "changes" field that follows.  Top
+ * three bits are actual packet type.  For backward compatibility
+ * and in the interest of conserving bits, numbers are chosen so the
+ * IP protocol version number (4) which normally appears in this nibble
+ * means "IP packet".

+.Os
+.Dt PPPCTL 8
+.Sh NAME
+.Nm pppctl
+.Nd PPP control program
+.Sh SYNOPSIS
+.Nm
+.Op Fl v
+.Op Fl t Ar n
+.Op Fl p Ar passwd
+.Xo Oo Ar host : Oc Ns
+.Ar Port | LocalSocket
+.Xc
+.Oo
+.Sm off
+.Ar command Oo ; Ar command Oc Ar ...
+.Sm on
+.Oc
+.Sh DESCRIPTION
+This program provides command line control of the
+.Xr ppp 8
+daemon.  Its primary use is to facilitate simple scripts that
+control a running daemon.
+.Pp
+.Nm Pppctl
+is passed at least one argument, specifying the socket on which
+.Nm ppp
+is listening.  Refer to the
+.Sq set server
+command of
+.Nm ppp
+for details.  If the socket contains a leading '/', it
+is taken as an
+.Dv AF_LOCAL
+socket.  If it contains a colon, it is treated as a
+.Ar host : Ns Ar port
+pair, otherwise it is treated as a TCP port specification on the
+local machine (127.0.0.1).  Both the
+.Ar host
+and
+.Ar port
+may be specified numerically if you wish to avoid a DNS lookup
+or don't have an entry for the given port in
+.Pa /etc/services .
+.Pp
+All remaining arguments are concatenated to form the
+.Ar command Ns (s)
+that will be sent to the
+.Nm ppp
+daemon.  If any semi-colon characters are found, they are treated as
+.Ar command
+delimiters, allowing more than one
+.Ar command
+in a given
+.Sq session .
+For example:
+.Bd -literal -offset indent
+pppctl 3000 set timeout 300\\; show timeout
+.Ed
+.Pp
+Don't forget to escape or quote the ';' as it is a special character
+for most shells.
+.Pp
+If no
+.Ar command
+arguments are given,
+.Nm
+enters interactive mode, where commands are read from standard input.
+When reading commands, the
+.Xr editline 3
+library is used, allowing command-line editing (with
+.Xr editrc 5
+defining editing behaviour).  The history size
+defaults to
+.Em 20 lines .
+.Pp
+The following command line options are available:
+.Bl -tag -width Ds
+.It Fl v
+Display all data sent to and received from the
+.Nm ppp
+daemon.  Normally,
+.Nm
+displays only non-prompt lines received.  This option is ignored in
+interactive mode.
+.It Fl t Ar n
+Use a timeout of
+.Ar n
+instead of the default 2 seconds when connecting.  This may be required
+if you wish to control a daemon over a slow (or even a dialup) link.
+.It Fl p Ar passwd
+Specify the password required by the
+.Nm ppp
+daemon.  If this switch is not used,
+.Nm
+will prompt for a password once it has successfully connected to
+.Nm ppp .
+.El
+.Sh EXAMPLES
+If you run
+.Nm ppp
+in
+.Fl auto
+mode,
+.Nm
+can be used to automate many frequent tasks (you can actually control
+.Nm ppp
+in any mode except interactive mode).  Use of the
+.Fl p
+option is discouraged (even in scripts that aren't readable by others)
+as a
+.Xr ps 1
+listing may reveal your secret.
+.Pp
+The best way to allow easy, secure
+.Nm
+access is to create a local server socket in
+.Pa /etc/ppp/ppp.conf
+(in the correct section) like this:
+.Bd -literal -offset indent
+set server /var/run/internet "" 0177
+.Ed
+.Pp
+This will instruct
+.Nm ppp
+to create a local domain socket, with srw------- permissions and no
+password, allowing access only to the user that invoked
+.Nm ppp .
+Refer to the
+.Xr ppp 8
+man page for further details.
+.Pp
+You can now create some easy-access scripts.  To connect to the internet:
+.Bd -literal -offset indent
+#! /bin/sh
+test $# -eq 0 && time=300 || time=$1
+exec pppctl /var/run/internet set timeout $time\\; dial
+.Ed
+.Pp
+To disconnect:
+.Bd -literal -offset indent
+#! /bin/sh
+exec pppctl /var/run/internet set timeout 300\\; close
+.Ed
+.Pp
+To check if the line is up:
+.Bd -literal -offset indent
+#! /bin/sh
+pppctl -p '' -v /var/run/internet quit | grep ^PPP >/dev/null
+if [ $? -eq 0 ]; then
+  echo Link is up
+else
+  echo Link is down
+fi
+.Ed
+.Pp
+You can even make a generic script:
+.Bd -literal -offset indent
+#! /bin/sh
+exec pppctl /var/run/internet "$@"
+.Ed
+.Pp
+You could also use
+.Nm
+to control when dial-on-demand works.  Suppose you want
+.Nm ppp
+to run all the time, but you want to prevent dial-out between 8pm and 8am
+each day.  However, any connections active at 8pm should continue to remain
+active until they are closed or naturally time out.
+.Pp
+A
+.Xr cron 8
+entry for 8pm which runs
+.Bd -literal -offset indent
+pppctl /var/run/internet set filter dial 0 deny 0 0
+.Ed
+.Pp
+will block all further dial requests, and the corresponding 8am entry
+.Bd -literal -offset indent
+pppctl /var/run/internet set filter dial -1
+.Ed
+.Pp
+will allow them again.
+.Sh ENVIRONMENT
+The following environment variables are understood by
+.Nm
+when in interactive mode:
+.Bl -tag -width XXXXXXXXXX
+.It Dv EL_SIZE
+The number of history lines.  The default is 20.
+.It Dv EL_EDITOR
+The edit mode.  Only values of "emacs" and "vi" are accepted.  Other values
+are silently ignored.  This environment variable will override the
+.Ar bind -v
+and
+.Ar bind -e
+commands in
+.Pa ~/.editrc .
+.El
+.Sh SEE ALSO
+.Xr ps 1 ,
+.Xr editline 3 ,
+.Xr editrc 5 ,
+.Xr services 5 ,
+.Xr ppp 8
+.Sh HISTORY
+The
+.Nm
+command first appeared in
+.Fx 2.2.5 .

+This is the README file for ppp-2.3, a package which implements the
+Point-to-Point Protocol (PPP) to provide Internet connections over
+serial lines.
+
+
+Introduction.
+*************
+
+The Point-to-Point Protocol (PPP) provides a standard way to establish
+a network connection over a serial link.  At present, this package
+supports IP and the protocols layered above IP, such as TCP and UDP.
+The Linux port of this package also has support for IPX.
+
+This software consists of two parts:
+
+- Kernel code, which establishes a network interface and passes
+packets between the serial port, the kernel networking code and the
+PPP daemon (pppd).  This code is implemented using STREAMS modules on
+SunOS 4.x, Solaris 2.x, System V Release 4, and OSF/1, and as a
+line discipline under Ultrix, NextStep, NetBSD, FreeBSD, and Linux.
+
+- The PPP daemon (pppd), which negotiates with the peer to establish
+the link and sets up the ppp network interface.  Pppd includes support
+for authentication, so you can control which other systems may make a
+PPP connection and what IP addresses they may use.
+
+
+Installation.
+*************
+
+The file SETUP contains general information about setting up your
+system for using PPP.  There is also a README file for each supported
+system, which contains more specific details for installing PPP on
+that system.  The supported systems, and the corresponding README
+files, are:
+
+	Digital Unix (OSF/1)		README.osf
+	Linux				README.linux
+	NetBSD, FreeBSD			README.bsd
+	NeXTStep			README.next
+	Solaris 2			README.sol2
+	SunOS 4.x			README.sunos4
+	System V Release 4		README.svr4
+	Ultrix 4.x			README.ultrix
+
+Unfortunately, AIX 4 is no longer supported, since I don't have a
+maintainer for the AIX 4 port.  If you want to volunteer, contact me.
+The Ultrix port is untested, as I no longer have access to an Ultrix
+box.
+
+In each case you start by running the ./configure script.  This works
+out which operating system you are using and creates symbolic links to
+the appropriate makefiles.  You then run `make' to compile the
+user-level code, and (as root) `make install' to install the
+user-level programs pppd, chat and pppstats.
+
+The procedures for installing the kernel code vary from system to
+system.  On some systems, the kernel code can be loaded into a running
+kernel using a `modload' facility.  On others, the kernel image has to
+be recompiled and the system rebooted.  See the README.* files for
+details.
+
+N.B. Since 2.3.0, leaving the permitted IP addresses column of the
+pap-secrets or chap-secrets file empty means that no addresses are
+permitted.  You need to put a "*" in that column to allow the peer to
+use any IP address.  (This only applies where the peer is
+authenticating itself to you, of course.)
+
+
+What's new in ppp-2.3.5.
+************************
+
+* Minor corrections to the Digital UNIX and NetBSD ports.
+
+* A workaround to avoid tickling a bug in the `se' serial port driver
+on Sun PCI Ultra machines running Solaris.
+
+* Fixed a bug in the negotiation of the Microsoft WINS server address
+option.
+
+* Fixed a bug in the Linux port where it would fail for kernel
+versions above 2.1.99.
+
+
+What was new in ppp-2.3.4.
+**************************
+
+* The NeXT port has been updated, thanks to Steve Perkins.
+
+* ppp-2.3.4 compiles and works under Solaris 2.6, using either gcc or
+cc.
+
+* With the Solaris, SVR4 and SunOS ports, you can control the choice
+of C compiler, C compiler options, and installation directories by
+editing the svr4/Makedefs or sunos4/Makedefs file.
+
+* Until now, we have been using the number 24 to identify Deflate
+compression in the CCP negotiations, which was the number in the draft
+RFC describing Deflate.  The number actually assigned to Deflate is
+26.  The code has been changed to use 26, but to allow the use of 24
+for now for backwards compatibility.  (This can be disabled with the
+`nodeflatedraft' option to pppd.)
+
+* Fixed some bugs in the linux driver and deflate compressor which
+were causing compression problems, including corrupting long
+incompressible packets sometimes.
+
+* Fixes to the PAM and shadow password support in pppd, from Al
+Longyear and others.
+
+* Pppd now sets some environment variables for scripts it invokes
+(ip-up/down, auth-ip/down), giving information about the connection.
+The variables it sets are PEERNAME, IPLOCAL, IPREMOTE, UID, DEVICE,
+SPEED, and IFNAME.
+
+* Pppd now has an `updetach' option, which will cause it to detach
+from its controlling terminal once the link has come up (i.e. once it
+is available for IP traffic).
+
+
+What was new in ppp-2.3.3.
+**************************
+
+* Fixed compilation problems under SunOS.
+
+* Fixed a bug introduced into chat in 2.3.2, and compilation problems
+introduced into the MS-CHAP implementation in 2.3.2.
+
+* The linux kernel driver has been updated for recent 2.1-series
+kernel changes, and it now will ask kerneld to load compression
+modules when required, if the kernel is configured to support kerneld.
+
+* Pppd should now compile correctly under linux on systems with glibc.
+
+
+What was new in ppp-2.3.2.
+**************************
+
+* In 2.3.1, I made a change which was intended to make pppd able to
+detect loss of CD during or immediately after the connection script
+runs.  Unfortunately, this had the side-effect that the connection
+script wouldn't work at all on some systems.  This change has been
+reversed.
+
+* Fix compilation problems in the Linux kernel driver.
+
+
+What was new in ppp-2.3.1.
+**************************
+
+* Enhancements to chat, thanks to Francis Demierre.  Chat can now
+accept comments in the chat script file, and has new SAY, HANGUP,
+CLR_ABORT and CLR_REPORT keywords.
+
+* Fixed a bug which causes 2.3.0 to crash Solaris systems.
+
+* Bug-fixes and restructuring of the Linux kernel driver.
+
+* The holdoff behaviour of pppd has been changed slightly: now, if
+the link comes up for IP (or other network protocol) traffic, we
+consider that the link has been successfully established, and don't
+enforce the holdoff period after the link goes down.
+
+* Pppd should now correctly wait for CD (carrier detect) from the
+modem, even when the serial port initially had CLOCAL set, and it
+should also detect loss of CD during or immediately after the
+connection script runs.
+
+* Under linux, pppd will work with older 2.2.0* version kernel
+drivers, although demand-dialling is not supported with them.
+
+* Minor bugfixes for pppd.
+
+
+What was new in ppp-2.3.
+************************
+
+* Demand-dialling.  Pppd now has a mode where it will establish the
+network interface immediately when it starts, but not actually bring
+the link up until it sees some data to be sent.  Look for the demand
+option description in the pppd man page.  Demand-dialling is not
+supported under Ultrix or NeXTStep.
+
+* Idle timeout.  Pppd will optionally terminate the link if no data
+packets are sent or received within a certain time interval.
+
+* Pppd now runs the /etc/ppp/auth-up script, if it exists, when the
+peer successfully authenticates itself, and /etc/ppp/auth-down when
+the connection is subsequently terminated.  This can be useful for
+accounting purposes.
+
+* A new packet compression scheme, Deflate, has been implemented.
+This uses the same compression method as `gzip'.  This method is free
+of patent or copyright restrictions, and it achieves better
+compression than BSD-Compress.  It does consume more CPU cycles for
+compression than BSD-Compress, but this shouldn't be a problem for
+links running at 100kbit/s or less.
+
+* There is no code in this distribution which is covered by Brad
+Clements' restrictive copyright notice.  The STREAMS modules for SunOS
+and OSF/1 have been rewritten, based on the Solaris 2 modules, which
+were written from scratch without any Clements code.
+
+* Pppstats has been reworked to clean up the output format somewhat.
+It also has a new -d option which displays data rate in kbyte/s for
+those columns which would normally display bytes.
+
+* Pppd options beginning with - or + have been renamed, e.g. -ip
+became noip, +chap became require-chap, etc.  The old options are
+still accepted for compatibility but may be removed in future.
+
+* Pppd now has some options (such as the new `noauth' option) which
+can only be specified if it is being run by root, or in an
+"privileged" options file: /etc/ppp/options or an options file in the
+/etc/ppp/peers directory.  There is a new "call" option to read
+options from a file in /etc/ppp/peers, making it possible for non-root
+users to make unauthenticated connections, but only to certain trusted
+peers.  My intention is to make the `auth' option the default in a
+future release.
+
+* Several minor new features have been added to pppd, including the
+maxconnect and welcome options.  Pppd will now terminate the
+connection when there are no network control protocols running.  The
+allowed IP address(es) field in the secrets files can now specify
+subnets (with a notation like 123.45.67.89/24) and addresses which are
+not acceptable (put a ! on the front).
+
+* Numerous bugs have been fixed (no doubt some have been introduced :-)
+Thanks to those who reported bugs in ppp-2.2.

+-------------------------
+This is the README file for ppp-2.2, a package which implements the
+Point-to-Point Protocol (PPP) to provide Internet connections over
+serial lines.
+
+
+Introduction.
+*************
+
+The Point-to-Point Protocol (PPP) provides a standard way to transmit
+datagrams over a serial link, as well as a standard way for the
+machines at either end of the link (the `peers') to negotiate various
+optional characteristics of the link.  Using PPP, a serial link can be
+used to transmit Internet Protocol (IP) datagrams, allowing TCP/IP
+connections between the peers.  PPP is defined in several RFC (Request
+For Comments) documents, in particular RFCs 1661, 1662, 1332 and 1334.
+Other RFCs describe standard ways to transmit datagrams from other
+network protocols (e.g., DECnet, OSI, Appletalk), but this package
+only supports IP.
+
+This software consists of two parts:
+
+- Kernel code, which establishes a network interface and passes
+packets between the serial port, the kernel networking code and the
+PPP daemon (pppd).  This code is implemented using STREAMS modules on
+SunOS 4.x, AIX 4.1 and OSF/1, and as a line discipline under Ultrix,
+NextStep, NetBSD, FreeBSD, and Linux.
+
+- The PPP daemon (pppd), which negotiates with the peer to establish
+the link and sets up the ppp network interface.  Pppd includes support
+for authentication, so you can control which other systems may make a
+PPP connection and what IP addresses they may use.
+
+
+What is new in ppp-2.2.
+***********************
+
+* More systems are now supported:
+
+  AIX 4, thanks to Charlie Wick,
+  OSF/1 on DEC Alpha, thanks to Steve Tate (srt@zaphod.csci.unt.edu),
+  NextStep 3.2 and 3.3, thanks to Philip-Andrew Prindeville
+	(philipp@res.enst.fr) and Steve Perkins (perkins@cps.msu.edu),
+  Solaris 2,
+
+in addition to NetBSD 1.0, SunOS 4.x, Ultrix 4.x, FreeBSD 2.0, and
+Linux.
+
+* Packet compression has been implemented.  This version implements
+CCP (Compression Control Protocol) and the BSD-Compress compression
+scheme according to the current draft RFCs.  This means that incoming
+and outgoing packets can be compressed with the LZW scheme (same as
+the `compress' command) using a code size of up to 15 bits.
+
+* Some bug fixes to the LCP protocol code.  In particular, pppd now
+correctly replies with a Configure-NAK (instead of a Configure-Reject)
+if the peer asks for CHAP and pppd is willing to do PAP but not CHAP.
+
+* The ip-up and ip-down scripts are now run with the real user ID set
+to root, and with an empty environment.  Clearing the environment
+fixes a security hole.
+
+* The kernel code on NetBSD, FreeBSD, NextStep and Ultrix has been
+restructured to make it easier to implement PPP over devices other
+than asynchronous tty ports (for example, synchronous serial ports).
+
+* pppd now looks at the list of interfaces in the system to determine
+what the netmask should be.  In most cases, this should eliminate the
+need to use the `netmask' option.
+
+* There is a new `papcrypt' option to pppd, which specifies that
+secrets in /etc/ppp/pap-secrets used for authenticating the peer are
+encrypted, so pppd always encrypts the peer's password before
+comparing it with the secret from /etc/ppp/pap-secrets.  This gives
+better security.
+
+
+Patents.
+********
+
+The BSD-Compress algorithm used for packet compression is the same as
+that used in the Unix "compress" command.  It is apparently covered by
+U.S. patents 4,814,746 (owned by IBM) and 4,558,302 (owned by Unisys),
+and corresponding patents in various other countries (but not
+Australia).  If this is of concern, you can build the package without
+including BSD-Compress.  To do this, edit net/ppp-comp.h to change the
+definition of DO_BSD_COMPRESS to 0.  The bsd-comp.c files are then no
+longer needed, so the references to bsd-comp.o may optionally be
+removed from the Makefiles.

+		pppd-2.1.1 release notes
+		Paul Mackerras   27 May 1994
+
+This file details the new and changed features in pppd since version 1.3.
+Briefly:
+	- the protocol code has been updated to conform with
+	  RFCs 1548, 1549, 1332 and 1334
+	- security has been improved
+	- functionality has been improved in various ways.
+
+
+NEW FEATURES
+
+* The option negotiation automaton has been updated to RFC1548.  LCP
+now rejects the Quality Protocol option, since LQR is not implemented
+yet.  IPCP now uses the IP-Address option, and falls back to the old
+IP-Addresses option if the IP-Address option is rejected.  IPCP also
+uses the new form of the VJ-Compression option.
+
+RFC1548 defines the "passive" option to mean that the automaton
+outputs configure-request packets initially, but does not close down
+if no answer is received.  A valid configure-request received will
+restart the negotiation.  The "silent" option has been added with the
+old meaning of "passive", i.e. the automaton will not output
+configure-requests until it receives a valid one from the peer.
+
+* More systems are supported: in addition to SunOS 4.x and BSD/Net-2
+derived systems, Ultrix and Linux are supported, thanks to Robert
+Olsson, Per Sundstrom, Michael Callahan and Al Longyear.
+
+* Options can be taken from files as well as the command line.  pppd
+reads options from the files /etc/ppp/options and ~/.ppprc before
+looking at the command line, and /etc/ppp/options.<ttyname> after
+interpreting the options on the command line.  An options file is
+parsed into a series of words, delimited by whitespace.  Whitespace
+can be included in a word by enclosing the word in quotes (").
+Backslash (\) quotes the following character.  A hash (#) starts a
+comment, which continues until the end of the line.  In addition, the
+`file' option causes pppd to read options from a file.  pppd will
+report and error and exit if ~/.ppprc or the file given as the
+argument to the `file' option cannot be read by the user who invoked
+pppd.
+
+* On those systems, such as NetBSD, where the serial line speed is
+stored in the termios structure in bits per second (i.e. B9600 ==
+9600), it is possible to set any speed.
+
+* If desired, pppd will output LCP echo-request frames periodically
+while the link is up, and take the link down if no replies are
+received to a user-configurable number of echo-requests.  This can be
+used to detect that the serial connection has been broken on those
+systems which don't have hardware modem control lines.
+
+AUTHENTICATION
+
+Previous versions of pppd have provided no control over which IP
+addresses the peer can use.  Thus it is possible for the peer to
+impersonate another host on the local network, leading to various
+security holes.  In addition, the authentication mechanisms were quite
+weak: if the peer refused to agree to authenticate, pppd would print a
+warning message but still allow the link to come up.  The CHAP
+implementation also appeared to be quite broken (has anybody actually
+used it?).  
+
+This new version of pppd addresses these problems.  My aim has been to
+provide system administrators with sufficient access control that PPP
+access to a server machine can be provided to legitimate users without
+fear of compromising the security of the server or the network it's
+on.  In part this is provided by the /etc/ppp/options file, where the
+administrator can place options to require authentication which cannot
+be disabled by users.  Thus the new pppd can made setuid-root and run
+by users.
+
+The behaviour where pppd refuses to run unless the /etc/ppp/options
+file is present and readable by pppd is now the default behaviour.  If
+you really want pppd to run without the presence of the
+/etc/ppp/options file, you will have to include -DREQ_SYSOPTIONS=0 on
+the compilation command line.
+
+The options related to authentication are:
+
+    auth	Require authentication from the peer.  If neither
+		+chap or +pap is also given, either CHAP or PAP
+		authentication will be accepted.
+    +chap	Require CHAP authentication from the peer.
+    +pap	Require PAP authentication from the peer.
+    -chap	Don't agree to authenticate ourselves with the peer
+		using CHAP.
+    -pap	Don't agree to authenticate ourselves using PAP.
+    +ua <f>	Get username and password for authenticating ourselves
+		with the peer using PAP from file <f>.
+    name <n>	Use <n> as the local name for authentication.
+    usehostname	Use this machine's hostname as the local name for
+		authentication.
+    remotename <n>  Use <n> as the name of the peer for authentication.
+    login	If the peer authenticates using PAP, check the
+		supplied username and password against the system
+		password database, and make a wtmp entry.
+    user <n>	Use <n> as the username for authenticating ourselves
+		using PAP.
+
+The defaults are to agree to authenticate if requested, and to not
+require authentication from the peer.  However, pppd will not agree to
+authenticate itself with a particular protocol if it has no secrets
+which could be used to do so.
+
+Authentication is based on secrets, which are selected from secrets
+files (/etc/ppp/pap-secrets for PAP, /etc/ppp/chap-secrets for CHAP).
+Both secrets files have the same format, and both can store secrets
+for several combinations of server (authenticating peer) and client
+(peer being authenticated).  Note that each end can be both a server
+and client, and that different protocols can be used in the two
+directions if desired.
+
+A secrets file is parsed into words as for a options file.  A secret
+is specified by a line containing at least 3 words, in the order
+client, server, secret.  Any following words on the same line are
+taken to be a list of acceptable IP addresses for that client.  If
+there are only 3 words on the line, it is assumed that any IP address
+is OK; to disallow all IP addresses, use "-".  If the secret starts
+with an `@', what follows is assumed to be the name of a file from
+which to read the secret.  A "*" as the client or server name matches
+any name.  When selecting a secret, pppd takes the best match, i.e.
+the match with the fewest wildcards.
+
+Thus a secrets file contains both secrets for use in authenticating
+other hosts, plus secrets which we use for authenticating ourselves to
+others.  Which secret to use is chosen based on the names of the host
+(the `local name') and its peer (the `remote name').  The local name
+is set as follows:
+
+	if the `usehostname' option is given,
+	then the local name is the hostname of this machine
+		(with the domain appended, if given)
+
+	else if the `name' option is given,
+	then use the argument of the first `name' option seen
+
+	else if the local IP address is specified with a
+		host name (e.g. `sirius:')
+	then use that host name
+
+	else use the hostname of this machine
+		(with the domain appended, if given)
+
+When authenticating ourselves using PAP, there is also a `username'
+which is the local name by default, but can be set with the `user'
+option or the `+ua' option.
+
+The remote name is set as follows:
+
+	if the `remotename' option is given,
+	then use the argument of the last `remotename' option seen
+
+	else if the remote IP address is specified with a
+		host name (e.g. `avago:')
+	then use that host name
+
+	else the remote name is the null string "".
+
+Secrets are selected from the PAP secrets file as follows:
+
+- For authenticating the peer, look for a secret with client ==
+username specified in the PAP authenticate-request, and server ==
+local name.
+
+- For authenticating ourselves to the peer, look for a secret with
+client == our username, server == remote name.
+
+When authenticating the peer with PAP, a secret of "" matches any
+password supplied by the peer.  If the password doesn't match the
+secret, the password is encrypted using crypt() and checked against
+the secret again; thus secrets for authenticating the peer can be
+stored in encrypted form.  If the `login' option was specified, the
+username and password are also checked against the system password
+database.  Thus, the system administrator can set up the pap-secrets
+file to allow PPP access only to certain users, and to restrict the
+set of IP addresses that each user can use.
+
+Secrets are selected from the CHAP secrets file as follows:
+
+- For authenticating the peer, look for a secret with client == name
+specified in the CHAP-Response message, and server == local name.
+
+- For authenticating ourselves to the peer, look for a secret with
+client == local name, and server == name specified in the
+CHAP-Challenge message.
+
+Authentication must be satisfactorily completed before IPCP (or any
+other Network Control Protocol) can be started.  If authentication
+fails, pppd will terminated the link (by closing LCP).  If IPCP
+negotiates an unacceptable IP address for the remote host, IPCP will
+be closed.  IP packets cannot be sent or received until IPCP is
+successfully opened.
+
+(some examples needed here perhaps)
+
+
+ROUTING
+
+Setting the addresses on a ppp interface is sufficient to create a
+host route to the remote end of the link.  Sometimes it is desirable
+to add a default route through the remote host, as in the case of a
+machine whose only connection to the Internet is through the ppp
+interface.  The `defaultroute' option causes pppd to create such a
+default route when IPCP comes up, and delete it when the link is
+terminated.
+
+In some cases it is desirable to use proxy ARP, for example on a
+server machine connected to a LAN, in order to allow other hosts to
+communicate with the remote host.  The `proxyarp' option causes pppd
+to look for a network interface (an interface supporting broadcast and
+ARP, which is up and not a point-to-point or loopback interface) on
+the same subnet as the remote host.  If found, pppd creates a
+permanent, published ARP entry with the IP address of the remote host
+and the hardware address of the network interface found.
+

+
+
+SOFTWARE RESTRUCTURING
+
+Many of the source files for pppd have changed significantly from
+ppp-1.3, upon which it is based.  In particular:
+
+- the macros for system-dependent operations in pppd.h have mostly
+been removed.  Instead these operations are performed by procedures in
+sys-bsd.c (for BSD-4.4ish systems like NetBSD, 386BSD, etc.) or
+sys-str.c (for SunOS-based systems using STREAMS).  (I got sick of
+having to recompile everything every time I wanted to change one of
+those horrible macros.)
+
+- most of the system-dependent code in main.c has also been removed to
+sys-bsd.c and sys-str.c.
+
+- the option processing code in main.c has been removed to options.c.
+
+- the authentication code in main.c has been removed to auth.c, which
+also contains substantial amounts of new code.
+
+- fsm.c has changed significantly, and lcp.c, ipcp.c, and upap.c have
+changed somewhat.  chap.c has also changed significantly.
+
+
+STILL TO DO
+
+* sort out appropriate modem control and implement the persist option
+properly; add an `answer' option for auto-answering a modem.
+
+* add an inactivity timeout and demand dialing.
+
+* implement link quality monitoring.
+
+* implement other network control protocols.

+.SH NAME
+pppd \- Point to Point Protocol daemon
+.SH SYNOPSIS
+.B pppd
+[
+.I tty_name
+] [
+.I speed
+] [
+.I options
+]
+.SH DESCRIPTION
+.LP
+The Point-to-Point Protocol (PPP) provides a method for transmitting
+datagrams over serial point-to-point links.  PPP
+is composed of three parts: a method for encapsulating datagrams over
+serial links, an extensible Link Control Protocol (LCP), and
+a family of Network Control Protocols (NCP) for establishing
+and configuring different network-layer protocols.
+.LP
+The encapsulation scheme is provided by driver code in the kernel.
+Pppd provides the basic LCP, authentication support, and an NCP for
+establishing and configuring the Internet Protocol (IP) (called the IP
+Control Protocol, IPCP).
+.SH FREQUENTLY USED OPTIONS
+.TP
+.I <tty_name>
+Communicate over the named device.  The string "/dev/" is prepended if
+necessary.  If no device name is given, or if the name of the terminal
+connected to the standard input is given, pppd
+will use that terminal, and will not fork to put itself in the
+background.  This option is privileged if the \fInoauth\fR option is
+used.
+.TP
+.I <speed>
+Set the baud rate to <speed> (a decimal number).  On systems such as
+4.4BSD and NetBSD, any speed can be specified, providing that it is
+supported by the serial device driver.  Other systems
+(e.g. SunOS, Linux) allow only a limited set of speeds.
+.TP
+.B active-filter \fIfilter-expression
+Specifies a packet filter to be applied to data packets to determine
+which packets are to be regarded as link activity, and therefore reset
+the idle timer, or cause the link to be brought up in demand-dialling
+mode.  This option is useful in conjunction with the
+\fBidle\fR option if there are packets being sent or received
+regularly over the link (for example, routing information packets)
+which would otherwise prevent the link from ever appearing to be idle.
+The \fIfilter-expression\fR syntax is as described for tcpdump(1),
+except that qualifiers which are inappropriate for a PPP link, such as
+\fBether\fR and \fBarp\fR, are not permitted.  Generally the filter
+expression should be enclosed in single-quotes to prevent whitespace
+in the expression from being interpreted by the shell.
+This option
+only available
+if both the kernel and pppd were compiled with PPP_FILTER defined.
+.TP
+.B asyncmap \fI<map>
+Set the async character map to <map>.  This map describes which
+control characters cannot be successfully received over the serial
+line.  Pppd will ask the peer to send these characters as a 2-byte
+escape sequence.  The argument is a 32 bit hex number with each bit
+representing a character to escape.  Bit 0 (00000001) represents the
+character 0x00; bit 31 (80000000) represents the character 0x1f or ^_.
+If multiple \fIasyncmap\fR options are given, the values are ORed
+together.  If no \fIasyncmap\fR option is given, no async character
+map will be negotiated for the receive direction; the peer should then
+escape \fIall\fR control characters.  To escape transmitted
+characters, use the \fIescape\fR option.
+.TP
+.B auth
+Require the peer to authenticate itself before allowing network
+packets to be sent or received.
+.TP
+.B call \fIname
+Read options from the file /etc/ppp/peers/\fIname\fR.  This file may
+contain privileged options, such as \fInoauth\fR, even if pppd
+is not being run by root.  The \fIname\fR string may not begin with /
+or include .. as a pathname component.  The format of the options file
+is described below.
+.TP
+.B connect \fIscript
+Use the executable or shell command specified by \fIscript\fR to set
+up the serial line.  This script would typically use the chat(8)
+program to dial the modem and start the remote ppp session.  This
+option is privileged if the \fInoauth\fR option is used.
+.TP
+.B connect-max-attempts \fI<n>
+Attempt dial-out connection to remote system no more than specified number
+of times (default = 1).  If the connection is not made, pppd will exit.
+Requires that \fBpersist\fR has been specified.
+.TP
+.B crtscts
+Use hardware flow control (i.e. RTS/CTS) to control the flow of data
+on the serial port.  If neither the \fIcrtscts\fR nor the
+\fInocrtscts\fR option is given, the hardware flow control setting
+for the serial port is left unchanged.
+.TP
+.B defaultroute
+Add a default route to the system routing tables, using the peer as
+the gateway, when IPCP negotiation is successfully completed.
+This entry is removed when the PPP connection is broken.  This option
+is privileged if the \fInodefaultroute\fR option has been specified.
+.TP
+.B disconnect \fIscript
+Run the executable or shell command specified by \fIscript\fR after
+pppd has terminated the link.  This script could, for example, issue
+commands to the modem to cause it to hang up if hardware modem control
+signals were not available.  The disconnect script is not run if the
+modem has already hung up.  This option is privileged if the
+\fInoauth\fR option is used.
+.TP
+.B escape \fIxx,yy,...
+Specifies that certain characters should be escaped on transmission
+(regardless of whether the peer requests them to be escaped with its
+async control character map).  The characters to be escaped are
+specified as a list of hex numbers separated by commas.  Note that
+almost any character can be specified for the \fIescape\fR option,
+unlike the \fIasyncmap\fR option which only allows control characters
+to be specified.  The characters which may not be escaped are those
+with hex values 0x20 - 0x3f or 0x5e.
+.TP
+.B file \fIname
+Read options from file \fIname\fR (the format is described below).
+The file must be readable by the user who has invoked pppd.
+.TP
+.B lock
+Specifies that pppd should create a UUCP-style lock file for the
+serial device to ensure exclusive access to the device.
+.TP
+.B mru \fIn
+Set the MRU [Maximum Receive Unit] value to \fIn\fR.
+Pppd
+will ask the peer to send packets of no more than \fIn\fR bytes.  The
+minimum MRU value is 128.  The default MRU value is 1500.  A value of
+296 is recommended for slow links (40 bytes for TCP/IP header + 256
+bytes of data).
+.TP
+.B mtu \fIn
+Set the MTU [Maximum Transmit Unit] value to \fIn\fR.  Unless the
+peer requests a smaller value via MRU negotiation, pppd will
+request that the kernel networking code send data packets of no more
+than \fIn\fR bytes through the PPP network interface.
+.TP
+.B passive
+Enables the "passive" option in the LCP.  With this option, pppd will
+attempt to initiate a connection; if no reply is received from the
+peer, pppd will then just wait passively for a valid LCP packet from
+the peer, instead of exiting, as it would without this option.
+.SH OPTIONS
+.TP
+.I <local_IP_address>\fB:\fI<remote_IP_address>
+Set the local and/or remote interface IP addresses.  Either one may be
+omitted.  The IP addresses can be specified with a host name or in
+decimal dot notation (e.g. 150.234.56.78).  The default local
+address is the (first) IP address of the system (unless the
+\fInoipdefault\fR
+option is given).  The remote address will be obtained from the peer
+if not specified in any option.  Thus, in simple cases, this option is
+not required.  If a local and/or remote IP address is specified with
+this option, pppd
+will not accept a different value from the peer in the IPCP
+negotiation, unless the \fIipcp-accept-local\fR and/or
+\fIipcp-accept-remote\fR options are given, respectively.
+.TP
+.B bsdcomp \fInr,nt
+Request that the peer compress packets that it sends, using the
+BSD-Compress scheme, with a maximum code size of \fInr\fR bits, and
+agree to compress packets sent to the peer with a maximum code size of
+\fInt\fR bits.  If \fInt\fR is not specified, it defaults to the value
+given for \fInr\fR.  Values in the range 9 to 15 may be used for
+\fInr\fR and \fInt\fR; larger values give better compression but
+consume more kernel memory for compression dictionaries.
+Alternatively, a value of 0 for \fInr\fR or \fInt\fR disables
+compression in the corresponding direction.  Use \fInobsdcomp\fR or
+\fIbsdcomp 0\fR to disable BSD-Compress compression entirely.
+.TP
+.B chap-interval \fIn
+If this option is given, pppd will rechallenge the peer every \fIn\fR
+seconds.
+.TP
+.B chap-max-challenge \fIn
+Set the maximum number of CHAP challenge transmissions to \fIn\fR
+(default 10).
+.TP
+.B chap-restart \fIn
+Set the CHAP restart interval (retransmission timeout for challenges)
+to \fIn\fR seconds (default 3).
+.TP
+.B debug
+Enables connection debugging facilities.
+If this option is given, pppd will log the contents of all
+control packets sent or received in a readable form.  The packets are
+logged through syslog with facility \fIdaemon\fR and level
+\fIdebug\fR.  This information can be directed to a file by setting up
+/etc/syslog.conf appropriately (see syslog.conf(5)).
+.TP
+.B default-asyncmap
+Disable asyncmap negotiation, forcing all control characters to be
+escaped for both the transmit and the receive direction.
+.TP
+.B default-mru
+Disable MRU [Maximum Receive Unit] negotiation.  With this option,
+pppd will use the default MRU value of 1500 bytes for both the
+transmit and receive direction.
+.TP
+.B deflate \fInr,nt
+Request that the peer compress packets that it sends, using the
+Deflate scheme, with a maximum window size of \fI2**nr\fR bytes, and
+agree to compress packets sent to the peer with a maximum window size
+of \fI2**nt\fR bytes.  If \fInt\fR is not specified, it defaults to
+the value given for \fInr\fR.  Values in the range 8 to 15 may be used
+for \fInr\fR and \fInt\fR; larger values give better compression but
+consume more kernel memory for compression dictionaries.
+Alternatively, a value of 0 for \fInr\fR or \fInt\fR disables
+compression in the corresponding direction.  Use \fInodeflate\fR or
+\fIdeflate 0\fR to disable Deflate compression entirely.  (Note: pppd
+requests Deflate compression in preference to BSD-Compress if the peer
+can do either.)
+.TP
+.B demand
+Initiate the link only on demand, i.e. when data traffic is present.
+With this option, the remote IP address must be specified by the user
+on the command line or in an options file.  Pppd will initially
+configure the interface and enable it for IP traffic without
+connecting to the peer.  When traffic is available, pppd will
+connect to the peer and perform negotiation, authentication, etc.
+When this is completed, pppd will commence passing data packets
+(i.e., IP packets) across the link.
+
+The \fIdemand\fR option implies the \fIpersist\fR option.  If this
+behaviour is not desired, use the \fInopersist\fR option after the
+\fIdemand\fR option.  The \fIidle\fR and \fIholdoff\fR
+options are also useful in conjuction with the \fIdemand\fR option.
+.TP
+.B domain \fId
+Append the domain name \fId\fR to the local host name for authentication
+purposes.  For example, if gethostname() returns the name porsche, but
+the fully qualified domain name is porsche.Quotron.COM, you could
+specify \fIdomain Quotron.COM\fR.  Pppd would then use the name
+\fIporsche.Quotron.COM\fR for looking up secrets in the secrets file,
+and as the default name to send to the peer when authenticating itself
+to the peer.  This option is privileged.
+.TP
+.B holdoff \fIn
+Specifies how many seconds to wait before re-initiating the link after
+it terminates.  This option only has any effect if the \fIpersist\fR
+or \fIdemand\fR option is used.  The holdoff period is not applied if
+the link was terminated because it was idle.
+.TP
+.B idle \fIn
+Specifies that pppd should disconnect if the link is idle for \fIn\fR
+seconds.  The link is idle when no data packets (i.e. IP packets) are
+being sent or received.  Note: it is not advisable to use this option
+with the \fIpersist\fR option without the \fIdemand\fR option.
+If the \fBactive-filter\fR
+option is given, data packets which are rejected by the specified
+activity filter also count as the link being idle.
+.TP
+.B ipcp-accept-local
+With this option, pppd will accept the peer's idea of our local IP
+address, even if the local IP address was specified in an option.
+.TP
+.B ipcp-accept-remote
+With this option, pppd will accept the peer's idea of its (remote) IP
+address, even if the remote IP address was specified in an option.
+.TP
+.B ipcp-max-configure \fIn
+Set the maximum number of IPCP configure-request transmissions to
+\fIn\fR (default 10).
+.TP
+.B ipcp-max-failure \fIn
+Set the maximum number of IPCP configure-NAKs returned before starting
+to send configure-Rejects instead to \fIn\fR (default 10).
+.TP
+.B ipcp-max-terminate \fIn
+Set the maximum number of IPCP terminate-request transmissions to
+\fIn\fR (default 3).
+.TP
+.B ipcp-restart \fIn
+Set the IPCP restart interval (retransmission timeout) to \fIn\fR
+seconds (default 3).
+.TP
+.B ipparam \fIstring
+Provides an extra parameter to the ip-up and ip-down scripts.  If this
+option is given, the \fIstring\fR supplied is given as the 6th
+parameter to those scripts.
+.TP
+.B ipx
+Enable the IPXCP and IPX protocols.  This option is presently only
+supported under Linux, and only if your kernel has been configured to
+include IPX support.
+.TP
+.B ipx-network \fIn
+Set the IPX network number in the IPXCP configure request frame to
+\fIn\fR, a hexadecimal number (without a leading 0x).  There is no
+valid default.  If this option is not specified, the network number is
+obtained from the peer.  If the peer does not have the network number,
+the IPX protocol will not be started.
+.TP
+.B ipx-node \fIn\fB:\fIm
+Set the IPX node numbers.
+The two node numbers are separated from each
+other with a colon character.
+The first number \fIn\fR is the local
+node number.
+The second number \fIm\fR is the peer's node number.
+Each
+node number is a hexadecimal number, at most 10 digits long.
+The node
+numbers on the ipx-network must be unique.
+There is no valid
+default.
+If this option is not specified then the node numbers are
+obtained from the peer.
+.TP
+.B ipx-router-name \fI<string>
+Set the name of the router.
+This is a string and is sent to the peer
+as information data.
+.TP
+.B ipx-routing \fIn
+Set the routing protocol to be received by this option.
+More than one
+instance of \fIipx-routing\fR may be specified.
+The '\fInone\fR'
+option (0) may be specified as the only instance of ipx-routing.
+The
+values may be \fI0\fR for \fINONE\fR, \fI2\fR for \fIRIP/SAP\fR, and
+\fI4\fR for \fINLSP\fR.
+.TP
+.B ipxcp-accept-local
+Accept the peer's NAK for the node number specified in the ipx-node
+option.
+If a node number was specified, and non-zero, the default is
+to insist that the value be used.
+If you include this option then you
+will permit the peer to override the entry of the node number.
+.TP
+.B ipxcp-accept-network
+Accept the peer's NAK for the network number specified in the
+ipx-network option.
+If a network number was specified, and non-zero, the
+default is to insist that the value be used.
+If you include this
+option then you will permit the peer to override the entry of the node
+number.
+.TP
+.B ipxcp-accept-remote
+Use the peer's network number specified in the configure request
+frame.
+If a node number was specified for the peer and this option was
+not specified, the peer will be forced to use the value which you have
+specified.
+.TP
+.B ipxcp-max-configure \fIn
+Set the maximum number of IPXCP configure request frames which the
+system will send to \fIn\fR.
+The default is 10.
+.TP
+.B ipxcp-max-failure \fIn
+Set the maximum number of IPXCP NAK frames which the local system will
+send before it rejects the options.
+The default value is 3.
+.TP
+.B ipxcp-max-terminate \fIn
+Set the maximum nuber of IPXCP terminate request frames before the
+local system considers that the peer is not listening to them.
+The
+default value is 3.
+.TP
+.B kdebug \fIn
+Enable debugging code in the kernel-level PPP driver.  The argument
+\fIn\fR is a number which is the sum of the following values: 1 to
+enable general debug messages, 2 to request that the contents of
+received packets be printed, and 4 to request that the contents of
+transmitted packets be printed.  On most systems, messages printed by
+the kernel are logged by syslog(1) to a file as directed in the
+/etc/syslog.conf configuration file.
+.TP
+.B lcp-echo-failure \fIn
+If this option is given, pppd will presume the peer to be dead
+if \fIn\fR LCP echo-requests are sent without receiving a valid LCP
+echo-reply.  If this happens, pppd will terminate the
+connection.  Use of this option requires a non-zero value for the
+\fIlcp-echo-interval\fR parameter.  This option can be used to enable
+pppd to terminate after the physical connection has been broken
+(e.g., the modem has hung up) in situations where no hardware modem
+control lines are available.
+.TP
+.B lcp-echo-interval \fIn
+If this option is given, pppd will send an LCP echo-request frame to
+the peer every \fIn\fR seconds.  Normally the peer should respond to
+the echo-request by sending an echo-reply.  This option can be used
+with the \fIlcp-echo-failure\fR option to detect that the peer is no
+longer connected.
+.TP
+.B lcp-max-configure \fIn
+Set the maximum number of LCP configure-request transmissions to
+\fIn\fR (default 10).
+.TP
+.B lcp-max-failure \fIn
+Set the maximum number of LCP configure-NAKs returned before starting
+to send configure-Rejects instead to \fIn\fR (default 10).
+.TP
+.B lcp-max-terminate \fIn
+Set the maximum number of LCP terminate-request transmissions to
+\fIn\fR (default 3).
+.TP
+.B lcp-restart \fIn
+Set the LCP restart interval (retransmission timeout) to \fIn\fR
+seconds (default 3).
+.TP
+.B local
+Don't use the modem control lines.  With this option, pppd will ignore
+the state of the CD (Carrier Detect) signal from the modem and will
+not change the state of the DTR (Data Terminal Ready) signal.
+.TP
+.B login
+Use the system password database for authenticating the peer using
+PAP, and record the user in the system wtmp file.  Note that the peer
+must have an entry in the /etc/ppp/pap-secrets file as well as the
+system password database to be allowed access.
+.TP
+.B maxconnect \fIn
+Terminate the connection when it has been available for network
+traffic for \fIn\fR seconds (i.e. \fIn\fR seconds after the first
+network control protocol comes up).
+.TP
+.B modem
+Use the modem control lines.  This option is the default.  With this
+option, pppd will wait for the CD (Carrier Detect) signal from the
+modem to be asserted when opening the serial device (unless a connect
+script is specified), and it will drop the DTR (Data Terminal Ready)
+signal briefly when the connection is terminated and before executing
+the connect script.  On Ultrix, this option implies hardware flow
+control, as for the \fIcrtscts\fR option.
+.TP
+.B ms-dns \fI<addr>
+If pppd is acting as a server for Microsoft Windows clients, this
+option allows pppd to supply one or two DNS (Domain Name Server)
+addresses to the clients.  The first instance of this option specifies
+the primary DNS address; the second instance (if given) specifies the
+secondary DNS address.  (This option was present in some older
+versions of pppd under the name \fBdns-addr\fR.)
+.TP
+.B ms-wins \fI<addr>
+If pppd is acting as a server for Microsoft Windows or "Samba"
+clients, this option allows pppd to supply one or two WINS (Windows
+Internet Name Services) server addresses to the clients.  The first
+instance of this option specifies the primary WINS address; the second
+instance (if given) specifies the secondary WINS address.
+.TP
+.B name \fIname
+Set the name of the local system for authentication purposes to
+\fIname\fR.  This is a privileged option.  With this option, pppd will
+use lines in the secrets files which have \fIname\fR as the second
+field when looking for a secret to use in authenticating the peer.  In
+addition, unless overridden with the \fIuser\fR option, \fIname\fR
+will be used as the name to send to the peer when authenticating the
+local system to the peer.  (Note that pppd does not append the domain
+name to \fIname\fR.)
+.TP
+.B netmask \fIn
+Set the interface netmask to \fIn\fR, a 32 bit netmask in "decimal dot"
+notation (e.g. 255.255.255.0).  If this option is given, the value
+specified is ORed with the default netmask.  The default netmask is
+chosen based on the negotiated remote IP address; it is the
+appropriate network mask for the class of the remote IP address, ORed
+with the netmasks for any non point-to-point network interfaces in the
+system which are on the same network.
+.TP
+.B noaccomp
+Disable Address/Control compression in both directions (send and
+receive).
+.TP
+.B noauth
+Do not require the peer to authenticate itself.  This option is
+privileged if the \fIauth\fR option is specified in /etc/ppp/options.
+.TP
+.B nobsdcomp
+Disables BSD-Compress compression; \fBpppd\fR will not request or
+agree to compress packets using the BSD-Compress scheme.
+.TP
+.B noccp
+Disable CCP (Compression Control Protocol) negotiation.  This option
+should only be required if the peer is buggy and gets confused by
+requests from pppd for CCP negotiation.
+.TP
+.B nocrtscts
+Disable hardware flow control (i.e. RTS/CTS) on the serial port.  If
+neither the \fIcrtscts\fR nor the \fInocrtscts\fR option is given,
+the hardware flow control setting for the serial port is left
+unchanged.
+.TP
+.B nodefaultroute
+Disable the \fIdefaultroute\fR option.  The system administrator who
+wishes to prevent users from creating default routes with pppd
+can do so by placing this option in the /etc/ppp/options file.
+.TP
+.B nodeflate
+Disables Deflate compression; pppd will not request or agree to
+compress packets using the Deflate scheme.
+.TP
+.B nodetach
+Don't detach from the controlling terminal.  Without this option, if a
+serial device other than the terminal on the standard input is
+specified, pppd will fork to become a background process.
+.TP
+.B noip
+Disable IPCP negotiation and IP communication.  This option should
+only be required if the peer is buggy and gets confused by requests
+from pppd for IPCP negotiation.
+.TP
+.B noipdefault
+Disables the default behaviour when no local IP address is specified,
+which is to determine (if possible) the local IP address from the
+hostname.  With this option, the peer will have to supply the local IP
+address during IPCP negotiation (unless it specified explicitly on the
+command line or in an options file).
+.TP
+.B noipx
+Disable the IPXCP and IPX protocols.  This option should only be
+required if the peer is buggy and gets confused by requests from pppd
+for IPXCP negotiation.
+.TP
+.B nomagic
+Disable magic number negotiation.  With this option, pppd cannot
+detect a looped-back line.  This option should only be needed if the
+peer is buggy.
+.TP
+.B nopcomp
+Disable protocol field compression negotiation in both the receive and
+the transmit direction.
+.TP
+.B nopersist
+Exit once a connection has been made and terminated.  This is the
+default unless the \fIpersist\fR or \fIdemand\fR option has been
+specified.
+.TP
+.B nopredictor1
+Do not accept or agree to Predictor-1 comprssion.
+.TP
+.B noproxyarp
+Disable the \fIproxyarp\fR option.  The system administrator who
+wishes to prevent users from creating proxy ARP entries with pppd can
+do so by placing this option in the /etc/ppp/options file.
+.TP
+.B novj
+Disable Van Jacobson style TCP/IP header compression in both the
+transmit and the receive direction.
+.TP
+.B novjccomp
+Disable the connection-ID compression option in Van Jacobson style
+TCP/IP header compression.  With this option, pppd will not omit the
+connection-ID byte from Van Jacobson compressed TCP/IP headers, nor
+ask the peer to do so.
+.TP
+.B papcrypt
+Indicates that all secrets in the /etc/ppp/pap-secrets file which are
+used for checking the identity of the peer are encrypted, and thus
+pppd should not accept a password which, before encryption, is
+identical to the secret from the /etc/ppp/pap-secrets file.
+.TP
+.B pap-max-authreq \fIn
+Set the maximum number of PAP authenticate-request transmissions to
+\fIn\fR (default 10).
+.TP
+.B pap-restart \fIn
+Set the PAP restart interval (retransmission timeout) to \fIn\fR
+seconds (default 3).
+.TP
+.B pap-timeout \fIn
+Set the maximum time that pppd will wait for the peer to authenticate
+itself with PAP to \fIn\fR seconds (0 means no limit).
+.TP
+.B pass-filter \fIfilter-expression
+Specifies a packet filter to applied to data packets being sent or
+received to determine which packets should be allowed to pass.
+Packets which are rejected by the filter are silently discarded.  This
+option can be used to prevent specific network daemons (such as
+routed) using up link bandwidth, or to provide a basic firewall
+capability.
+The \fIfilter-expression\fR syntax is as described for tcpdump(1),
+except that qualifiers which are inappropriate for a PPP link, such as
+\fBether\fR and \fBarp\fR, are not permitted.  Generally the filter
+expression should be enclosed in single-quotes to prevent whitespace
+in the expression from being interpreted by the shell.  Note that it
+is possible to apply different constraints to incoming and outgoing
+packets using the \fBinbound\fR and \fBoutbound\fR qualifiers.
+This
+option is currently only available under NetBSD, and then only if both
+the kernel and pppd were compiled with PPP_FILTER defined.
+.TP
+.B persist
+Do not exit after a connection is terminated; instead try to reopen
+the connection.
+.TP
+.B predictor1
+Request that the peer compress frames that it sends using Predictor-1
+compression, and agree to compress transmitted frames with Predictor-1
+if requested.  This option has no effect unless the kernel driver
+supports Predictor-1 compression.
+.TP
+.B proxyarp
+Add an entry to this system's ARP [Address Resolution Protocol] table
+with the IP address of the peer and the Ethernet address of this
+system.  This will have the effect of making the peer appear to other
+systems to be on the local ethernet.
+.TP
+.B remotename \fIname
+Set the assumed name of the remote system for authentication purposes
+to \fIname\fR.
+.TP
+.B refuse-chap
+With this option, pppd will not agree to authenticate itself to the
+peer using CHAP.
+.TP
+.B refuse-pap
+With this option, pppd will not agree to authenticate itself to the
+peer using PAP.
+.TP
+.B require-chap
+Require the peer to authenticate itself using CHAP [Challenge
+Handshake Authentication Protocol] authentication.
+.TP
+.B require-pap
+Require the peer to authenticate itself using PAP [Password
+Authentication Protocol] authentication.
+.TP
+.B silent
+With this option, pppd will not transmit LCP packets to initiate a
+connection until a valid LCP packet is received from the peer (as for
+the `passive' option with ancient versions of pppd).
+.TP
+.B usehostname
+Enforce the use of the hostname (with domain name appended, if given)
+as the name of the local system for authentication purposes (overrides
+the \fIname\fR option).
+.TP
+.B user \fIname
+Sets the name used for authenticating the local system to the peer to
+\fIname\fR.
+.TP
+.B vj-max-slots \fIn
+Sets the number of connection slots to be used by the Van Jacobson
+TCP/IP header compression and decompression code to \fIn\fR, which
+must be between 2 and 16 (inclusive).
+.TP
+.B welcome \fIscript
+Run the executable or shell command specified by \fIscript\fR before
+initiating PPP negotiation, after the connect script (if any) has
+completed.  This option is privileged if the \fInoauth\fR option is
+used.
+.TP
+.B xonxoff
+Use software flow control (i.e. XON/XOFF) to control the flow of data on
+the serial port.
+.SH OPTIONS FILES
+Options can be taken from files as well as the command line.  Pppd
+reads options from the files /etc/ppp/options, ~/.ppprc and
+/etc/ppp/options.\fIttyname\fR (in that order) before processing the
+options on the command line.  (In fact, the command-line options are
+scanned to find the terminal name before the options.\fIttyname\fR
+file is read.)  In forming the name of the options.\fIttyname\fR file,
+the initial /dev/ is removed from the terminal name, and any remaining
+/ characters are replaced with dots.
+.PP
+An options file is parsed into a series of words, delimited by
+whitespace.  Whitespace can be included in a word by enclosing the
+word in double-quotes (").  A backslash (\\) quotes the following character.
+A hash (#) starts a comment, which continues until the end of the
+line.  There is no restriction on using the \fIfile\fR or \fIcall\fR
+options within an options file.
+.SH SECURITY
+.I pppd
+provides system administrators with sufficient access control that PPP
+access to a server machine can be provided to legitimate users without
+fear of compromising the security of the server or the network it's
+on.  In part this is provided by the /etc/ppp/options file, where the
+administrator can place options to restrict the ways in which pppd can
+be used, and in part by the PAP and CHAP secrets files, where the
+administrator can restrict the set of IP addresses which individual
+users may use.
+.PP
+The normal way that pppd should be set up is to have the \fIauth\fR
+option in the /etc/ppp/options file.  (This may become the default in
+later releases.)  If users wish to use pppd to dial out to a peer
+which will refuse to authenticate itself (such as an internet service
+provider), the system administrator should create an options file
+under /etc/ppp/peers containing the \fInoauth\fR option, the name of
+the serial port to use, and the \fIconnect\fR option (if required),
+plus any other appropriate options.  In this way, pppd can be set up
+to allow non-privileged users to make unauthenticated connections only
+to trusted peers.
+.PP
+As indicated above, some security-sensitive options are privileged,
+which means that they may not be used by an ordinary non-privileged
+user running a setuid-root pppd, either on the command line, in the
+user's ~/.ppprc file, or in an options file read using the \fIfile\fR
+option.  Privileged options may be used in /etc/ppp/options file or in
+an options file read using the \fIcall\fR option.  If pppd is being
+run by the root user, privileged options can be used without
+restriction.
+.SH AUTHENTICATION
+Authentication is the process whereby one peer convinces the other of
+its identity.  This involves the first peer sending its name to the
+other, together with some kind of secret information which could only
+come from the genuine authorized user of that name.  In such an
+exchange, we will call the first peer the "client" and the other the
+"server".  The client has a name by which it identifies itself to the
+server, and the server also has a name by which it identifies itself
+to the client.  Generally the genuine client shares some secret (or
+password) with the server, and authenticates itself by proving that it
+knows that secret.  Very often, the names used for authentication
+correspond to the internet hostnames of the peers, but this is not
+essential.
+.LP
+At present, pppd supports two authentication protocols: the Password
+Authentication Protocol (PAP) and the Challenge Handshake
+Authentication Protocol (CHAP).  PAP involves the client sending its
+name and a cleartext password to the server to authenticate itself.
+In contrast, the server initiates the CHAP authentication exchange by
+sending a challenge to the client (the challenge packet includes the
+server's name).  The client must respond with a response which
+includes its name plus a hash value derived from the shared secret and
+the challenge, in order to prove that it knows the secret.
+.LP
+The PPP protocol, being symmetrical, allows both peers to require the
+other to authenticate itself.  In that case, two separate and
+independent authentication exchanges will occur.  The two exchanges
+could use different authentication protocols, and in principle,
+different names could be used in the two exchanges.
+.LP
+The default behaviour of pppd is to agree to authenticate if
+requested, and to not require authentication from the peer.  However,
+pppd will not agree to authenticate itself with a particular protocol
+if it has no secrets which could be used to do so.
+.LP
+Pppd stores secrets for use in authentication in secrets
+files (/etc/ppp/pap-secrets for PAP, /etc/ppp/chap-secrets for CHAP).
+Both secrets files have the same format.  The secrets files can
+contain secrets for pppd to use in authenticating itself to other
+systems, as well as secrets for pppd to use when authenticating other
+systems to itself.
+.LP
+Each line in a secrets file contains one secret.  A given secret is
+specific to a particular combination of client and server - it can
+only be used by that client to authenticate itself to that server.
+Thus each line in a secrets file has at least 3 fields: the name of
+the client, the name of the server, and the secret.  These fields may
+be followed by a list of the IP addresses that the specified client
+may use when connecting to the specified server.
+.LP
+A secrets file is parsed into words as for a options file, so the
+client name, server name and secrets fields must each be one word,
+with any embedded spaces or other special characters quoted or
+escaped.  Any following words on the same line are taken to be a list
+of acceptable IP addresses for that client, or an
+override for "local:remote" addresses (the same format used on the
+command line or in the options file) when on a line that contains a
+specific client name (not a wildcard nor empty).
+If there are only 3 words
+on the line, or if the first word is "-", then all IP addresses are
+disallowed.  To allow any address, use "*".
+A word starting with "!" indicates that the
+specified address is \fInot\fR acceptable.  An address may be followed
+by "/" and a number \fIn\fR, to indicate a whole subnet, i.e. all
+addresses which have the same value in the most significant \fIn\fR
+bits.  Note that case is significant in the client and server names
+and in the secret.
+.LP
+If the secret starts with an `@', what follows is assumed to be the
+name of a file from which to read the secret.  A "*" as the client or
+server name matches any name.  When selecting a secret, pppd takes the
+best match, i.e.  the match with the fewest wildcards.
+.LP
+Thus a secrets file contains both secrets for use in authenticating
+other hosts, plus secrets which we use for authenticating ourselves to
+others.  When pppd is authenticating the peer (checking the peer's
+identity), it chooses a secret with the peer's name in the first
+field and the name of the local system in the second field.  The
+name of the local system defaults to the hostname, with the domain
+name appended if the \fIdomain\fR option is used.  This default can be
+overridden with the \fIname\fR option, except when the
+\fIusehostname\fR option is used.
+.LP
+When pppd is choosing a secret to use in authenticating itself to the
+peer, it first determines what name it is going to use to identify
+itself to the peer.  This name can be specified by the user with the
+\fIuser\fR option.  If this option is not used, the name defaults to
+the name of the local system, determined as described in the previous
+paragraph.  Then pppd looks for a secret with this name in the first
+field and the peer's name in the second field.  Pppd will know the
+name of the peer if CHAP authentication is being used, because the
+peer will have sent it in the challenge packet.  However, if PAP is being
+used, pppd will have to determine the peer's name from the options
+specified by the user.  The user can specify the peer's name directly
+with the \fIremotename\fR option.  Otherwise, if the remote IP address
+was specified by a name (rather than in numeric form), that name will
+be used as the peer's name.  Failing that, pppd will use the null
+string as the peer's name.
+.LP
+When authenticating the peer with PAP, the supplied password is first
+compared with the secret from the secrets file.  If the password
+doesn't match the secret, the password is encrypted using crypt() and
+checked against the secret again.  Thus secrets for authenticating the
+peer can be stored in encrypted form if desired.  If the
+\fIpapcrypt\fR option is given, the first (unencrypted) comparison is
+omitted, for better security.
+.LP
+Furthermore, if the \fIlogin\fR option was specified, the username and
+password are also checked against the system password database.  Thus,
+the system administrator can set up the pap-secrets file to allow PPP
+access only to certain users, and to restrict the set of IP addresses
+that each user can use.  Typically, when using the \fIlogin\fR option,
+the secret in /etc/ppp/pap-secrets would be "", which will match any
+password supplied by the peer.  This avoids the need to have the same
+secret in two places.
+.LP
+Additional checks are performed when the \fBlogin\fR option is used.
+If the file /etc/ppp/ppp.deny exists, and the user is listed in it,
+the authentication fails.  If the file /etc/ppp/ppp.shells exists and
+the user's normal login shell is not listed, the authentication fails.
+.LP
+Authentication must be satisfactorily completed before IPCP (or any
+other Network Control Protocol) can be started.  If the peer is
+required to authenticate itself, and fails to do so, pppd will
+terminated the link (by closing LCP).  If IPCP negotiates an
+unacceptable IP address for the remote host, IPCP will be closed.  IP
+packets can only be sent or received when IPCP is open.
+.LP
+In some cases it is desirable to allow some hosts which can't
+authenticate themselves to connect and use one of a restricted set of
+IP addresses, even when the local host generally requires
+authentication.  If the peer refuses to authenticate itself when
+requested, pppd takes that as equivalent to authenticating with PAP
+using the empty string for the username and password.  Thus, by adding
+a line to the pap-secrets file which specifies the empty string for
+the client and password, it is possible to allow restricted access to
+hosts which refuse to authenticate themselves.
+.SH ROUTING
+.LP
+When IPCP negotiation is completed successfully, pppd will inform the
+kernel of the local and remote IP addresses for the ppp interface.
+This is sufficient to create a host route to the remote end of the
+link, which will enable the peers to exchange IP packets.
+Communication with other machines generally requires further
+modification to routing tables and/or ARP (Address Resolution
+Protocol) tables.  In most cases the \fIdefaultroute\fR and/or
+\fIproxyarp\fR options are sufficient for this, but in some cases
+further intervention is required.  The /etc/ppp/ip-up script can be
+used for this.
+.LP
+Sometimes it is desirable to add a default route through the remote
+host, as in the case of a machine whose only connection to the
+Internet is through the ppp interface.  The \fIdefaultroute\fR option
+causes pppd to create such a default route when IPCP comes up, and
+delete it when the link is terminated.
+.LP
+In some cases it is desirable to use proxy ARP, for example on a
+server machine connected to a LAN, in order to allow other hosts to
+communicate with the remote host.  The \fIproxyarp\fR option causes
+pppd to look for a network interface on the same subnet as the remote
+host (an interface supporting broadcast and ARP, which is up and not a
+point-to-point or loopback interface).  If found, pppd creates a
+permanent, published ARP entry with the IP address of the remote host
+and the hardware address of the network interface found.
+.LP
+When the \fIdemand\fR option is used, the interface IP addresses have
+already been set at the point when IPCP comes up.  If pppd has not
+been able to negotiate the same addresses that it used to configure
+the interface (for example when the peer is an ISP that uses dynamic
+IP address assignment), pppd has to change the interface IP addresses
+to the negotiated addresses.  This may disrupt existing connections,
+and the use of demand dialling with peers that do dynamic IP address
+assignment is not recommended.
+.SH EXAMPLES
+.LP
+The following examples assume that the /etc/ppp/options file contains
+the \fIauth\fR option (as in the default /etc/ppp/options file in the
+ppp distribution).
+.LP
+Probably the most common use of pppd is to dial out to an ISP.  This
+can be done with a command such as
+.IP
+pppd call isp
+.LP
+where the /etc/ppp/peers/isp file is set up by the system
+administrator to contain something like this:
+.IP
+ttyS0 19200 crtscts
+.br
+connect '/usr/sbin/chat -v -f /etc/ppp/chat-isp'
+.br
+noauth
+.LP
+In this example, we are using chat to dial the ISP's modem and go
+through any logon sequence required.  The /etc/ppp/chat-isp file
+contains the script used by chat; it could for example contain
+something like this:
+.IP
+ABORT "NO CARRIER"
+.br
+ABORT "NO DIALTONE"
+.br
+ABORT "ERROR"
+.br
+ABORT "NO ANSWER"
+.br
+ABORT "BUSY"
+.br
+ABORT "Username/Password Incorrect"
+.br
+"" "at"
+.br
+OK "at&d0&c1"
+.br
+OK "atdt2468135"
+.br
+"name:" "^Umyuserid"
+.br
+"word:" "\\qmypassword"
+.br
+"ispts" "\\q^Uppp"
+.br
+"~-^Uppp-~"
+.LP
+See the chat(8) man page for details of chat scripts.
+.LP
+Pppd can also be used to provide a dial-in ppp service for users.  If
+the users already have login accounts, the simplest way to set up the
+ppp service is to let the users log in to their accounts and run pppd
+(installed setuid-root) with a command such as
+.IP
+pppd proxyarp
+.LP
+To allow a user to use the PPP facilities, you need to allocate an IP
+address for that user's machine and create an entry in
+/etc/ppp/pap-secrets or /etc/ppp/chap-secrets (depending on which
+authentication method the PPP implementation on the user's machine
+supports), so that the user's
+machine can authenticate itself.  For example, if Joe has a machine
+called "joespc" which is to be allowed to dial in to the machine
+called "server" and use the IP address joespc.my.net, you would add an
+entry like this to /etc/ppp/pap-secrets or /etc/ppp/chap-secrets:
+.IP
+joespc	server	"joe's secret"	joespc.my.net
+.LP
+Alternatively, you can create a username called (for example) "ppp",
+whose login shell is pppd and whose home directory is /etc/ppp.
+Options to be used when pppd is run this way can be put in
+/etc/ppp/.ppprc.
+.LP
+If your serial connection is any more complicated than a piece of
+wire, you may need to arrange for some control characters to be
+escaped.  In particular, it is often useful to escape XON (^Q) and
+XOFF (^S), using \fIasyncmap a0000\fR.  If the path includes a telnet,
+you probably should escape ^] as well (\fIasyncmap 200a0000\fR).  If
+the path includes an rlogin, you will need to use the \fIescape ff\fR
+option on the end which is running the rlogin client, since many
+rlogin implementations are not transparent; they will remove the
+sequence [0xff, 0xff, 0x73, 0x73, followed by any 8 bytes] from the
+stream.
+.SH DIAGNOSTICS
+.LP
+Messages are sent to the syslog daemon using facility LOG_DAEMON.
+(This can be overriden by recompiling pppd with the macro
+LOG_PPP defined as the desired facility.)  In order to see the error
+and debug messages, you will need to edit your /etc/syslog.conf file
+to direct the messages to the desired output device or file.
+.LP
+The \fIdebug\fR option causes the contents of all control packets sent
+or received to be logged, that is, all LCP, PAP, CHAP or IPCP packets.
+This can be useful if the PPP negotiation does not succeed or if
+authentication fails.
+If debugging is enabled at compile time, the \fIdebug\fR option also
+causes other debugging messages to be logged.
+.LP
+Debugging can also be enabled or disabled by sending a SIGUSR1 signal
+to the pppd process.  This signal acts as a toggle.
+.SH SCRIPTS
+Pppd invokes scripts at various stages in its processing which can be
+used to perform site-specific ancillary processing.  These scripts are
+usually shell scripts, but could be executable code files instead.
+Pppd does not wait for the scripts to finish.  The scripts are
+executed as root (with the real and effective user-id set to 0), so
+that they can do things such as update routing tables or run
+privileged daemons.  Be careful that the contents of these scripts do
+not compromise your system's security.  Pppd runs the scripts with
+standard input, output and error redirected to /dev/null, and with an
+environment that is empty except for some environment variables that
+give information about the link.  The environment variables that pppd
+sets are:
+.TP
+.B DEVICE
+The name of the serial tty device being used.
+.TP
+.B IFNAME
+The name of the network interface being used.
+.TP
+.B IPLOCAL
+The IP address for the local end of the link.  This is only set when
+IPCP has come up.
+.TP
+.B IPREMOTE
+The IP address for the remote end of the link.  This is only set when
+IPCP has come up.
+.TP
+.B PEERNAME
+The authenticated name of the peer.  This is only set if the peer
+authenticates itself.
+.TP
+.B SPEED
+The baud rate of the tty device.
+.TP
+.B UID
+The real user-id of the user who invoked pppd.
+.P
+Pppd invokes the following scripts, if they exist.  It is not an error
+if they don't exist.
+.TP
+.B /etc/ppp/auth-up
+A program or script which is executed after the remote system
+successfully authenticates itself.  It is executed with the parameters
+.IP
+\fIinterface-name peer-name user-name tty-device speed\fR
+.IP
+Note that this script is not executed if the peer doesn't authenticate
+itself, for example when the \fInoauth\fR option is used.
+.TP
+.B /etc/ppp/auth-down
+A program or script which is executed when the link goes down, if
+/etc/ppp/auth-up was previously executed.  It is executed in the same
+manner with the same parameters as /etc/ppp/auth-up.
+.TP
+.B /etc/ppp/ip-up
+A program or script which is executed when the link is available for
+sending and receiving IP packets (that is, IPCP has come up).  It is
+executed with the parameters
+.IP
+\fIinterface-name tty-device speed local-IP-address
+remote-IP-address ipparam\fR
+.TP
+.B /etc/ppp/ip-down
+A program or script which is executed when the link is no longer
+available for sending and receiving IP packets.  This script can be
+used for undoing the effects of the /etc/ppp/ip-up script.  It is
+invoked in the same manner and with the same parameters as the ip-up
+script.
+.TP
+.B /etc/ppp/ipx-up
+A program or script which is executed when the link is available for
+sending and receiving IPX packets (that is, IPXCP has come up).  It is
+executed with the parameters
+.IP
+\fIinterface-name tty-device speed network-number local-IPX-node-address
+remote-IPX-node-address local-IPX-routing-protocol remote-IPX-routing-protocol
+local-IPX-router-name remote-IPX-router-name ipparam pppd-pid\fR
+.IP
+The local-IPX-routing-protocol and remote-IPX-routing-protocol field
+may be one of the following:
+.IP
+NONE      to indicate that there is no routing protocol
+.br
+RIP       to indicate that RIP/SAP should be used
+.br
+NLSP      to indicate that Novell NLSP should be used
+.br
+RIP NLSP  to indicate that both RIP/SAP and NLSP should be used
+.TP
+.B /etc/ppp/ipx-down
+A program or script which is executed when the link is no longer
+available for sending and receiving IPX packets.  This script can be
+used for undoing the effects of the /etc/ppp/ipx-up script.  It is
+invoked in the same manner and with the same parameters as the ipx-up
+script.
+.SH FILES
+.TP
+.B /var/run/ppp\fIn\fB.pid \fR(BSD or Linux), \fB/etc/ppp/ppp\fIn\fB.pid \fR(others)
+Process-ID for pppd process on ppp interface unit \fIn\fR.
+.TP
+.B /etc/ppp/pap-secrets
+Usernames, passwords and IP addresses for PAP authentication.  This
+file should be owned by root and not readable or writable by any other
+user.  Pppd will log a warning if this is not the case.
+.TP
+.B /etc/ppp/chap-secrets
+Names, secrets and IP addresses for CHAP authentication.  As for
+/etc/ppp/pap-secrets, this file should be owned by root and not
+readable or writable by any other user.  Pppd will log a warning if
+this is not the case.
+.TP
+.B /etc/ppp/options
+System default options for pppd, read before user default options or
+command-line options.
+.TP
+.B ~/.ppprc
+User default options, read before /etc/ppp/options.\fIttyname\fR.
+.TP
+.B /etc/ppp/options.\fIttyname
+System default options for the serial port being used, read after
+~/.ppprc.  In forming the \fIttyname\fR part of this
+filename, an initial /dev/ is stripped from the port name (if
+present), and any slashes in the remaining part are converted to
+dots.
+.TP
+.B /etc/ppp/peers
+A directory containing options files which may contain privileged
+options, even if pppd was invoked by a user other than root.  The
+system administrator can create options files in this directory to
+permit non-privileged users to dial out without requiring the peer to
+authenticate, but only to certain trusted peers.
+.TP
+.B /etc/ppp/ppp.deny
+Lists users who may not use the system password PAP authentication.
+.TP
+.B /etc/ppp/ppp.shells
+Lists user shells which are approved for system password PAP authentication
+logins.
+.TP
+.B /usr/share/examples/pppd/
+Sample pppd configuration files.

+.SH NOTES
+The following signals have the specified effect when sent to pppd.
+.TP
+.B SIGINT, SIGTERM
+These signals cause pppd to terminate the link (by closing LCP),
+restore the serial device settings, and exit.
+.TP
+.B SIGHUP
+This signal causes pppd to terminate the link, restore the serial
+device settings, and close the serial device.  If the \fIpersist\fR or
+\fIdemand\fR option has been specified, pppd will try to reopen the
+serial device and start another connection (after the holdoff period).
+Otherwise pppd will exit.  If this signal is received during the
+holdoff period, it causes pppd to end the holdoff period immediately.
+.TP
+.B SIGUSR1
+This signal toggles the state of the \fIdebug\fR option.
+.TP
+.B SIGUSR2
+This signal causes pppd to renegotiate compression.  This can be
+useful to re-enable compression after it has been disabled as a result
+of a fatal decompression error.  (Fatal decompression errors generally
+indicate a bug in one or other implementation.)

+.SH DESCRIPTION
+The
+.B pppstats
+utility reports PPP-related statistics at regular intervals for the
+specified PPP interface.  If the interface is unspecified, it will
+default to ppp0.
+The display is split horizontally
+into input and output sections containing columns of statistics
+describing the properties and volume of packets received and
+transmitted by the interface.
+.PP
+The options are as follows:
+.TP
+.B -a
+Display absolute values rather than deltas.  With this option, all
+reports show statistics for the time since the link was initiated.
+Without this option, the second and subsequent reports show statistics
+for the time since the last report.
+.TP
+.B -c \fIcount
+Repeat the display
+.I count
+times.  If this option is not specified, the default repeat count is 1
+if the
+.B -w
+option is not specified, otherwise infinity.
+.TP
+.B -r
+Display additional statistics summarizing the compression ratio
+achieved by the packet compression algorithm in use.
+.TP
+.B -v
+Display additional statistics relating to the performance of the Van
+Jacobson TCP header compression algorithm.
+.TP
+.B -w \fIwait
+Pause
+.I wait
+seconds between each display.  If this option is not specified, the
+default interval is 5 seconds.
+.TP
+.B -z
+Instead of the standard display, show statistics indicating the
+performance of the packet compression algorithm in use.
+.PP
+The following fields are printed on the input side when the
+.B -z
+option is not used:
+.TP
+.B IN
+The total number of bytes received by this interface.
+.TP
+.B PACK
+The total number of packets received by this interface.
+.TP
+.B VJCOMP
+The number of header-compressed TCP packets received by this interface.
+.TP
+.B VJUNC
+The number of header-uncompressed TCP packets received by this
+interface.  Not reported when the
+.B -r
+option is specified.
+.TP
+.B VJERR
+The number of corrupted or bogus header-compressed TCP packets
+received by this interface.  Not reported when the
+.B -r
+option is specified.
+.TP
+.B VJTOSS
+The number of VJ header-compressed TCP packets dropped on reception by
+this interface because of preceding errors.  Only reported when the
+.B -v
+option is specified.
+.TP
+.B NON-VJ
+The total number of non-TCP packets received by this interface.
+Only
+reported when the
+.B -v
+option is specified.
+.TP
+.B RATIO
+The compression ratio achieved for received packets by the
+packet compression scheme in use, defined as the uncompressed size
+divided by the compressed size.
+Only reported when the
+.B -r
+option is specified.
+.TP
+.B UBYTE
+The total number of bytes received, after decompression of compressed
+packets.  Only reported when the
+.B -r
+option is specified.
+.PP
+The following fields are printed on the output side:
+.TP
+.B OUT
+The total number of bytes transmitted from this interface.
+.TP
+.B PACK
+The total number of packets transmitted from this interface.
+.TP
+.B VJCOMP
+The number of TCP packets transmitted from this interface with
+VJ-compressed TCP headers.
+.TP
+.B VJUNC
+The number of TCP packets transmitted from this interface with
+VJ-uncompressed TCP headers.
+Not reported when the
+.B -r
+option is specified.
+.TP
+.B NON-VJ
+The total number of non-TCP packets transmitted from this interface.
+Not reported when the
+.B -r
+option is specified.
+.TP
+.B VJSRCH
+The number of searches for the cached header entry for a VJ header
+compressed TCP packet.  Only reported when the
+.B -v
+option is specified.
+.TP
+.B VJMISS
+The number of failed searches for the cached header entry for a
+VJ header compressed TCP packet.  Only reported when the
+.B -v
+option is specified.
+.TP
+.B RATIO
+The compression ratio achieved for transmitted packets by the
+packet compression scheme in use, defined as the size
+before compression divided by the compressed size.
+Only reported when the
+.B -r
+option is specified.
+.TP
+.B UBYTE
+The total number of bytes to be transmitted, before packet compression
+is applied.  Only reported when the
+.B -r
+option is specified.
+.PP
+When the
+.B -z
+option is specified,
+.B pppstats
+instead displays the following fields, relating to the packet
+compression algorithm currently in use.  If packet compression is not
+in use, these fields will all display zeroes.  The fields displayed on
+the input side are:
+.TP
+.B COMPRESSED BYTE
+The number of bytes of compressed packets received.
+.TP
+.B COMPRESSED PACK
+The number of compressed packets received.
+.TP
+.B INCOMPRESSIBLE BYTE
+The number of bytes of incompressible packets (that is, those which
+were transmitted in uncompressed form) received.
+.TP
+.B INCOMPRESSIBLE PACK
+The number of incompressible packets received.
+.TP
+.B COMP RATIO
+The recent compression ratio for incoming packets, defined as the
+uncompressed size divided by the compressed size (including both
+compressible and incompressible packets).
+.PP
+The fields displayed on the output side are:
+.TP
+.B COMPRESSED BYTE
+The number of bytes of compressed packets transmitted.
+.TP
+.B COMPRESSED PACK
+The number of compressed packets transmitted.
+.TP
+.B INCOMPRESSIBLE BYTE
+The number of bytes of incompressible packets transmitted (that is,
+those which were transmitted in uncompressed form).
+.TP
+.B INCOMPRESSIBLE PACK
+The number of incompressible packets transmitted.
+.TP
+.B COMP RATIO
+The recent compression ratio for outgoing packets.

+.Sh SYNOPSIS
+.Nm
+.Bk -words
+.Ar interface prefix
+.Ek
+.Bk -words
+.Op Cm set | delete
+.Ek
+.Sh DESCRIPTION
+.Nm
+is used to assign an prefix
+to a network interface.
+This command is currently just a frontend of
+.Xr ifconfig 8 ,
+and is not recommended to be used.
+.Sh SEE ALSO
+.Xr netstat 1 ,
+.Xr netintro 4 ,
+.Xr ifconfig 8 ,
+.Xr rc 8
+.Sh HISTORY
+The
+.Nm
+command first appeared in WIDE/KAME IPv6 protocol stack kit.
+Previously, this command was used to manipulate prefixes separately
+from interface identifiers, intending to be used for prefix
+renumbering.
+However, it had been known that the manipulation mechanism was not
+friendly with traditional address management engine in the kernel.
+Thus, the KAME developers decided to invalidate the prefix
+manipulation mechanism, and to clarify the entire address/prefix
+manipulation in February 2001.
+Since then, this command has almost been obsoleted.
+All users should now use
+.Xr ifconfig 8 .
+.Pp
+IPv6 and IPsec support based on the KAME Project (http://www.kame.net/) stack
+was initially integrated into
+.Fx 4.0

+.Sh DESCRIPTION
+.Nm Pstat
+displays open file entry, swap space utilization,
+terminal state, and vnode data structures.
+.Pp
+If invoked as
+.Nm swapinfo
+the
+.Fl s
+option is implied, and only the
+.Fl k
+option is legal.
+.Pp
+The following options are available:
+.Bl -tag -width indent
+.It Fl n
+Print devices out by major/minor instead of name.
+.It Fl k
+Print sizes in kilobytes, regardless of the setting of the
+.Ev BLOCKSIZE
+environment variable.
+.It Fl T
+Print the number of used and free slots in several system tables.
+This is useful for checking to see how large system tables have become
+if the system is under heavy load.
+.It Fl f
+Print the open file table with these headings:
+.Bl -tag -width indent
+.It LOC
+The core location of this table entry.
+.It TYPE
+The type of object the file table entry points to.
+.It FLG
+Miscellaneous state variables encoded thus:
+.Pp
+.Bl -tag -width indent -compact
+.It R
+open for reading
+.It W
+open for writing
+.It A
+open for appending
+.It I
+signal pgrp when data ready
+.El
+.It CNT
+Number of processes that know this open file.
+.It MSG
+Number of messages outstanding for this file.
+.It DATA
+The location of the vnode table entry or socket structure for this file.
+.It OFFSET
+The file offset (see
+.Xr lseek 2 ) .
+.El
+.It Fl s
+Print information about swap space usage on all the
+swap areas compiled into the kernel.
+The first column is the device name of the partition.  The next column is
+the total space available in the partition.  The
+.Ar Used
+column indicates the total blocks used so far;  the
+.Ar Available
+column indicates how much space is remaining on each partition.
+The
+.Ar Capacity
+reports the percentage of space used.
+.Pp
+If more than one partition is configured into the system, totals for all
+of the statistics will be reported in the final line of the report.
+.Pp
+If you supply the option again, as in
+.Fl ss ,
+the system will display a breakdown of the swap bitmap/radix-tree.
+.It Fl t
+Print table for terminals
+with these headings:
+.Bl -tag -width indent
+.It RAW
+Number of characters in raw input queue.
+.It CAN
+Number of characters in canonicalized input queue.
+.It OUT
+Number of characters in output queue.
+.It MODE
+See
+.Xr tty 4 .
+.It ADDR
+Physical device address.
+.It DEL
+Number of delimiters (newlines) in canonicalized input queue.
+.It COL
+Calculated column position of terminal.
+.It STATE
+Miscellaneous state variables encoded thus:

+
+pw is a command-line driven passwd/group editor utility that provides
+an easy and safe means of modifying of any/all fields in the system
+password files, and has an add, modify and delete mode for user and
+group records. Command line options have been fashioned to be similar
+to those used by the Sun/shadow commands: useradd, usermod, userdel,
+groupadd, groupmod, groupdel, but combines all operations within the
+single command `pw'.
+
+User add mode also provides a means of easily setting system useradd
+defaults (see pw.conf.5), so that adding a user is as easy as issuing
+the command "pw useradd <loginid>". Creation of a unique primary
+group for each user and automatic membership in secondary groups
+is fully supported.
+
+This program may be FreeBSD specific, but should be trivial to port to
+other bsd4.4 variants.

+.Sh DESCRIPTION
+.Nm Pw
+is a command-line based editor for the system
+.Ar user
+and
+.Ar group
+files, allowing the superuser an easy to use and standardized way of adding,
+modifying and removing users and groups.
+Note that
+.Nm
+only operates on the local user and group files.  NIS users and groups must be
+maintained on the NIS server.
+.Nm Pw
+handles updating the
+.Pa passwd ,
+.Pa master.passwd ,
+.Pa group
+and the secure and insecure
+password database files, and must be run as root.
+.Pp
+The first one or two keywords provided to
+.Nm
+on the command line provide the context for the remainder of the arguments.
+The keywords
+.Ar user
+and
+.Ar group
+may be combined with
+.Ar add ,
+.Ar del ,
+.Ar mod ,
+.Ar show ,
+or
+.Ar next
+in any order.
+(For example,
+.Ar showuser ,
+.Ar usershow ,
+.Ar show user ,
+and
+.Ar user show
+all mean the same thing.)
+This flexibility is useful for interactive scripts calling
+.Nm
+for user and group database manipulation.
+Following these keywords, you may optionally specify the user or group name or numeric
+id as an alternative to using the
+.Fl n Ar name ,
+.Fl u Ar uid ,
+.Fl g Ar gid
+options.
+.Pp
+The following flags are common to most or all modes of operation:
+.Pp
+.Bl -tag -width "-G grouplist"
+.It Fl V Ar etcdir
+This flag sets an alternate location for the password, group and configuration files,
+and may be used to maintain a user/group database in an alternate location.
+If this switch is specified, the system
+.Pa /etc/pw.conf
+will not be sourced for default configuration data, but the file pw.conf in the
+specified directory will be used instead (or none, if it does not exist).
+The
+.Fl C
+flag may be used to override this behaviour.
+As an exception to the general rule where options must follow the operation
+type, the
+.Fl V
+flag may be used on the command line before the operation keyword.
+.It Fl C Ar config
+By default,
+.Nm
+reads the file
+.Pa /etc/pw.conf
+to obtain policy information on how new user accounts and groups are to be created.
+The
+.Fl C
+option specifies a different configuration file.
+While most of the contents of the configuration file may be overridden via
+command-line options, it may be more convenient to keep standard information in a
+configuration file.
+.It Fl q
+Use of this option causes
+.Nm
+to suppress error messages, which may be useful in interactive environments where it
+is preferable to interpret status codes returned by
+.Nm
+rather than messing up a carefully formatted display.
+.It Fl N
+This option is available in
+.Ar add
+and
+.Ar modify
+operations, and tells
+.Nm
+to output the result of the operation without updating the user or group
+databases.
+You may use the
+.Fl P
+option to switch between standard passwd and readable formats.
+.It Fl Y
+Using this option with any of the update modes causes
+.Nm
+to run
+.Xr make 1
+after changing to the directory
+.Pa /var/yp .
+This is intended to allow automatic updating of NIS database files.
+If separate passwd and group files are being used by NIS, then use the
+.Fl y Ar path
+option to specify the location of the NIS passwd database so that
+.Nm
+will concurrently update it with the system password
+databases.
+.El
+.Sh USER OPTIONS
+The following options apply to the
+.Ar useradd
+and
+.Ar usermod
+commands:
+.Pp
+.Bl -tag -width "-G grouplist"
+.It Fl n Ar name
+Specify the user/account name.
+.It Fl u Ar uid
+Specify the user/account numeric id.
+.Pp
+Usually, you only need to provide one or the other of these options, as the account
+name will imply the uid, or vice versa.
+However, there are times when you need to provide both.
+For example, when changing the uid of an existing user with
+.Ar usermod ,
+or overriding the default uid when creating a new account.
+If you wish
+.Nm
+to automatically allocate the uid to a new user with
+.Ar useradd ,
+then you should
+.Em not
+use the
+.Fl u
+option.
+You may also provide either the account or userid immediately after the
+.Ar useradd ,
+.Ar userdel ,
+.Ar usermod
+or
+.Ar usershow
+keywords on the command line without using the
+.Fl n
+or
+.Fl u
+options.
+.El
+.Pp
+.Bl -tag -width "-G grouplist"
+.It Fl c Ar comment
+This field sets the contents of the passwd GECOS field, which normally contains up
+to four comma-separated fields containing the user's full name, office or location,
+and work and home phone numbers.
+These sub-fields are used by convention only, however, and are optional.
+If this field is to contain spaces, you need to quote the comment itself with double
+quotes
+.Ql \&" .
+Avoid using commas in this field as these are used as sub-field separators, and the
+colon
+.Ql \&:
+character also cannot be used as this is the field separator for the passwd
+file itself.
+.It Fl d Ar dir
+This option sets the account's home directory.
+Normally, you will only use this if the home directory is to be different from the
+default determined from
+.Pa /etc/pw.conf
+- normally
+.Pa /home
+with the account name as a subdirectory.
+.It Fl e Ar date
+Set the account's expiration date.
+Format of the date is either a UNIX time in decimal, or a date in
+.Ql dd-mmm-yy[yy]
+format, where dd is the day, mmm is the month, either in numeric or alphabetic format
+('Jan', 'Feb', etc) and year is either a two or four digit year.
+This option also accepts a relative date in the form
+.Ql \&+n[mhdwoy]
+where
+.Ql \&n
+is a decimal, octal (leading 0) or hexadecimal (leading 0x) digit followed by the
+number of Minutes, Hours, Days, Weeks, Months or Years from the current date at
+which the expiration date is to be set.
+.It Fl p Ar date
+Set the account's password expiration date.
+This field is similar to the account expiration date option, except that it
+applies to forced password changes.
+This is set in the same manner as the
+.Fl e
+option.
+.It Fl g Ar group
+Set the account's primary group to the given group.
+.Ar group
+may be defined by either its name or group number.
+.It Fl G Ar grouplist
+Sets additional group memberships for an account.
+.Ar grouplist
+is a comma-separated list of group names or group numbers.
+The user's name is added to the group lists in
+.Pa /etc/group ,
+and
+removed from any groups not specified in
+.Ar grouplist .
+Note: a user should not be added to their primary group with
+.Ar grouplist .
+Also, group membership changes do not take effect for current user login
+sessions, requiring the user to reconnect to be affected by the changes.
+.It Fl L Ar class
+This option sets the login class for the user being created.
+See
+.Xr login.conf 5
+and
+.Xr passwd 5
+for more information on user login classes.
+.It Fl m
+This option instructs
+.Nm
+to attempt to create the user's home directory.
+While primarily useful when adding a new account with
+.Ar useradd ,
+this may also be of use when moving an existing user's home directory elsewhere on
+the filesystem.
+The new home directory is populated with the contents of the
+.Ar skeleton
+directory, which typically contains a set of shell configuration files that the
+user may personalize to taste.
+When
+.Fl m
+is used on an account with
+.Ar usermod ,
+existing configuration files in the user's home directory are
+.Em not
+overwritten from the skeleton files.
+.Pp
+When a user's home directory is created, it will by default be a subdirectory of the
+.Ar basehome
+directory as specified by the
+.Fl b
+option (see below), bearing the name of the new account.
+This can be overridden by the
+.Fl d
+option on the command line, if desired.
+.It Fl k Ar dir
+Set the
+.Ar skeleton
+directory, from which basic startup and configuration files are copied when
+the user's home directory is created.
+This option only has meaning when used with the
+.Fl d
+or
+.Fl m
+flags.
+.It Fl s Ar shell
+Set or changes the user's login shell to
+.Ar shell .
+If the path to the shell program is omitted,
+.Nm
+searches the
+.Ar shellpath
+specified in
+.Pa /etc/pw.conf
+and fills it in as appropriate.
+Note that unless you have a specific reason to do so, you should avoid
+specifying the path - this will allow
+.Nm
+to validate that the program exists and is executable.
+Specifying a full path (or supplying a blank "" shell) avoids this check
+and allows for such entries as
+.Pa /nonexistent
+that should be set for accounts not intended for interactive login.
+.It Fl h Ar fd
+This option provides a special interface by which interactive scripts can
+set an account password using
+.Nm .
+Because the command line and environment are fundamentally insecure mechanisms
+by which programs can accept information,
+.Nm
+will only allow setting of account and group passwords via a file descriptor
+(usually a pipe between an interactive script and the program).
+.Ar sh ,
+.Ar bash ,
+.Ar ksh
+and
+.Ar perl
+all possess mechanisms by which this can be done.
+Alternatively,
+.Nm
+will prompt for the user's password if
+.Fl h Ar 0
+is given, nominating
+.Em stdin
+as the file descriptor on which to read the password.
+Note that this password will be read only once and is intended
+for use by a script rather than for interactive use.
+If you wish to have new password confirmation along the lines of
+.Xr passwd 1 ,
+this must be implemented as part of an interactive script that calls
+.Nm .
+.Pp
+If a value of
+.Ql \&-
+is given as the argument
+.Ar fd ,
+then the password will be set to
+.Ql \&* ,
+rendering the account inaccessible via password-based login.
+.El
+.Pp
+It is possible to use
+.Ar useradd
+to create a new account that duplicates an existing user id.
+While this is normally considered an error and will be rejected, the
+.Fl o
+option overrides the check for duplicates and allows the duplication of
+the user id.
+This may be useful if you allow the same user to login under
+different contexts (different group allocations, different home
+directory, different shell) while providing basically the same
+permissions for access to the user's files in each account.
+.Pp
+The
+.Ar useradd
+command also has the ability to set new user and group defaults by using the
+.Fl D
+option.
+Instead of adding a new user,
+.Nm
+writes a new set of defaults to its configuration file,
+.Pa /etc/pw.conf .
+When using the
+.Fl D
+option, you must not use either
+.Fl n Ar name
+or
+.Fl u Ar uid
+or an error will result.
+Use of
+.Fl D
+changes the meaning of several command line switches in the
+.Ar useradd
+command.
+These are:
+.Bl -tag -width "-G grouplist"
+.It Fl D
+Set default values in
+.Pa /etc/pw.conf
+configuration file, or a different named configuration file if the
+.Fl C Ar config
+option is used.
+.It Fl b Ar dir
+Set the root directory in which user home directories are created.
+The default value for this is
+.Pa /home ,
+but it may be set elsewhere as desired.
+.It Fl e Ar days
+Set the default account expiration period in days.
+Unlike use without
+.Fl D ,
+the argument must be numeric, which specifies the number of days after creation when
+the account is to expire.
+A value of 0 suppresses automatic calculation of the expiry date.
+.It Fl p Ar days
+Set the default password expiration period in days.
+.It Fl g Ar group
+Set the default group for new users.
+If a blank group is specified using
+.Fl g Ar \&"" ,
+then new users will be allocated their own private primary group
+with the same name as their login name.
+If a group is supplied, either its name or uid may be given as an argument.
+.It Fl G Ar grouplist
+Set the default groups in which new users are granted membership.
+This is a separate set of groups from the primary group, and you should avoid
+nominating the same group as both primary and extra groups.
+In other words, these extra groups determine membership in groups
+.Em other than
+the primary group.
+.Ar grouplist
+is a comma-separated list of group names or ids, and are always
+stored in
+.Pa /etc/pw.conf
+by their symbolic names.
+.It Fl L Ar class
+This option sets the default login class for new users.
+.It Fl k Ar dir
+Set the default
+.Em skeleton
+directory, from which prototype shell and other initialization files are copied when
+.Nm
+creates a user's home directory.
+.It Xo
+.Fl u Ar min , Ns Ar max ,
+.Fl i Ar min , Ns Ar max
+.Xc
+These options set the minimum and maximum user and group ids allocated for new accounts
+and groups created by
+.Nm .
+The default values for each is 1000 minimum and 32000 maximum.
+.Ar min
+and
+.Ar max
+are both numbers, where max must be greater than min, and both must be between 0
+and 32767.
+In general, user and group ids less than 100 are reserved for use by the system,
+and numbers greater than 32000 may also be reserved for special purposes (used by
+some system daemons).
+.It Fl w Ar method
+The
+.Fl w
+option sets the default method used to set passwords for newly created user accounts.
+.Ar method
+is one of:
+.Pp
+.Bl -tag -width random -offset indent -compact
+.It no
+disable login on newly created accounts
+.It yes
+force the password to be the account name
+.It none
+force a blank password
+.It random
+generate a random password
+.El
+.Pp
+The
+.Ql \&random
+or
+.Ql \&no
+methods are the most secure; in the former case,
+.Nm
+generates a password and prints it to stdout, which is suitable where you issue
+users with passwords to access their accounts rather than having the user nominate
+their own (possibly poorly chosen) password.
+The
+.Ql \&no
+method requires that the superuser use
+.Xr passwd 1
+to render the account accessible with a password.
+.It Fl y Ar path
+This sets the pathname of the database used by NIS if you are not sharing
+the information from
+.Pa /etc/master.passwd
+directly with NIS.
+You should only set this option for NIS servers.
+.El
+.Pp
+The
+.Ar userdel
+command has only three valid options.
+The
+.Fl n Ar name
+and
+.Fl u Ar uid
+options have already been covered above.
+The additional option is:
+.Bl -tag -width "-G grouplist"
+.It Fl r
+This tells
+.Nm
+to remove the user's home directory and all of its contents.
+.Nm Pw
+errs on the side of caution when removing files from the system.
+Firstly, it will not do so if the uid of the account being removed is also used by
+another account on the system, and the 'home' directory in the password file is
+a valid path that commences with the character
+.Ql \&/ .
+Secondly, it will only remove files and directories that are actually owned by
+the user, or symbolic links owned by anyone under the user's home directory.
+Finally, after deleting all contents owned by the user only empty directories
+will be removed.
+If any additional cleanup work is required, this is left to the administrator.
+.El
+.Pp
+Mail spool files and crontabs are always removed when an account is deleted as these
+are unconditionally attached to the user name.
+Jobs queued for processing by
+.Ar at
+are also removed if the user's uid is unique and not also used by another account on the
+system.
+.Pp
+The
+.Ar usershow
+command allows viewing of an account in one of two formats.
+By default, the format is identical to the format used in
+.Pa /etc/master.passwd
+with the password field replaced with a
+.Ql \&* .
+If the
+.Fl P
+option is used, then
+.Nm
+outputs the account details in a more human readable form.
+If the
+.Fl 7
+option is used, the account details are shown in v7 format.
+The
+.Fl a
+option lists all users currently on file.
+Using
+.Fl F
+forces
+.Nm
+to print the details of an account even if it does not exist.
+.Pp
+The command
+.Ar usernext
+returns the next available user and group ids separated by a colon.
+This is normally of interest only to interactive scripts or front-ends
+that use
+.Nm .
+.Sh GROUP OPTIONS
+The
+.Fl C
+and
+.Fl q
+options (explained at the start of the previous section) are available
+with the group manipulation commands.
+Other common options to all group-related commands are:
+.Bl -tag -width "-m newmembers"
+.It Fl n Ar name
+Specify the group name.
+.It Fl g Ar gid
+Specify the group numeric id.
+.Pp
+As with the account name and id fields, you will usually only need
+to supply one of these, as the group name implies the uid and vice
+versa.
+You will only need to use both when setting a specific group id
+against a new group or when changing the uid of an existing group.
+.It Fl M Ar memberlist
+This option provides an alternative way to add existing users to a
+new group (in groupadd) or replace an existing membership list (in
+groupmod).
+.Ar memberlist
+is a comma separated list of valid and existing user names or uids.
+.It Fl m Ar newmembers
+Similar to
+.Fl M ,
+this option allows the
+.Em addition
+of existing users to a group without replacing the existing list of
+members.
+Login names or user ids may be used, and duplicate users are
+silently eliminated.
+.El
+.Pp
+.Ar groupadd
+also has a
+.Fl o
+option that allows allocation of an existing group id to a new group.
+The default action is to reject an attempt to add a group, and this option overrides
+the check for duplicate group ids.
+There is rarely any need to duplicate a group id.
+.Pp
+The
+.Ar groupmod
+command adds one additional option:
+.Pp
+.Bl -tag -width "-m newmembers"
+.It Fl l Ar name
+This option allows changing of an existing group name to
+.Ql \&name .
+The new name must not already exist, and any attempt to duplicate an existing group
+name will be rejected.
+.El
+.Pp
+Options for
+.Ar groupshow
+are the same as for
+.Ar usershow ,
+with the
+.Fl g Ar gid
+replacing
+.Fl u Ar uid
+to specify the group id.
+The
+.Fl 7
+option does not apply to the
+.Ar groupshow
+command.
+.Pp
+The command
+.Ar groupnext
+returns the next available group id on standard output.
+.Sh USER LOCKING
+.Nm Pw
+supports a simple password locking mechanism for users; it works by
+prepending the string
+.Ql *LOCKED*
+to the beginning of the password field in
+.Pa master.passwd
+to prevent successful authentication.
+.Pp
+The
+.Ar lock
+and
+.Ar unlock
+commands take a user name or uid of the account to lock or unlock,
+respectively.  The
+.Fl V ,
+.Fl C ,
+and
+.Fl q
+options as described above are accepted by these commands.
+.Sh DIAGNOSTICS
+.Nm Pw
+returns EXIT_SUCCESS on successful operation, otherwise
+.Nm
+returns one of the
+following exit codes defined by
+.Xr sysexits 3
+as follows:
+.Bl -tag -width xxxx
+.It EX_USAGE
+.Bl -bullet -compact
+.It
+Command line syntax errors (invalid keyword, unknown option).
+.El
+.It EX_NOPERM
+.Bl -bullet -compact

+.It

+.It EX_CONFIG
+.Bl -bullet -compact
+.It

+.El
+.El
+.Sh NOTES
+For a summary of options available with each command, you can use
+.Dl pw [command] help
+For example,
+.Dl pw useradd help
+lists all available options for the useradd operation.
+.Pp
+.Nm Pw
+allows 8-bit characters in the passwd GECOS field (user's full name,
+office, work and home phone number subfields), but disallows them in
+user login and group names.
+Use 8-bit characters with caution, as connection to the Internet will
+require that your mail transport program supports 8BITMIME, and will
+convert headers containing 8-bit characters to 7-bit quoted-printable
+format.
+.Xr sendmail 8
+does support this.
+Use of 8-bit characters in the GECOS field should be used in
+conjunction with the user's default locale and character set
+and should not be implemented without their use.
+Using 8-bit characters may also affect other
+programs that transmit the contents of the GECOS field over the
+Internet, such as
+.Xr fingerd 8 ,
+and a small number of TCP/IP clients, such as IRC, where full names
+specified in the passwd file may be used by default.

+.Dt PW.CONF 5
+.Os
+.Sh NAME
+.Nm pw.conf
+.Nd format of the pw.conf configuration file
+.Sh DESCRIPTION
+The file
+.Aq Pa /etc/pw.conf
+contains configuration data for the
+.Xr pw 8
+program.
+The
+.Xr pw 8
+program is used for maintenance of the system password and group
+files, allowing users and groups to be added, deleted and changed.
+This file may be modified via the
+.Xr pw 8
+command using the
+.Ar useradd
+command and the
+.Fl D
+option, or by editing it directly with a text editor.
+.Pp
+Each line in
+.Aq Pa /etc/pw.conf
+is treated either a comment or as configuration data;
+blank lines and lines commencing with a
+.Ql \&#
+character are considered comments, and any remaining lines are
+examined for a leading keyword, followed by corresponding data.
+.Pp
+Keywords recognized by
+.Xr pw 8
+are:
+.Bl -tag -width password_days -offset indent -compact
+.It defaultpasswd
+affect passwords generated for new users
+.It reuseuids
+reuse gaps in uid sequences
+.It reusegids
+reuse gaps in gid sequences
+.It nispasswd
+path to the NIS passwd database
+.It skeleton
+where to obtain default home contents
+.It newmail
+mail to send to new users
+.It logfile
+log user/group modifications to this file
+.It home
+root directory for home directories
+.It shellpath
+paths in which to locate shell programs
+.It shells
+list of valid shells (without path)
+.It defaultshell
+default shell (without path)
+.It defaultgroup
+default group
+.It extragroups
+add new users to this groups
+.It defaultclass
+place new users in this login class
+.It minuid
+.It maxuid
+range of valid default user ids
+.It mingid
+.It maxgid
+range of valid default group ids
+.It expire_days
+days after which account expires
+.It password_days
+days after which password expires
+.El
+.Pp
+Valid values for
+.Ar defaultpasswd
+are:
+.Bl -tag -width password_days -offset indent -compact
+.It no
+disable login on newly created accounts
+.It yes
+force the password to be the account name
+.It none
+force a blank password
+.It random
+generate a random password
+.El
+.Pp
+The second and third options are insecure and should be avoided if
+possible on a publicly accessible system.
+The first option requires that the superuser run
+.Xr passwd 1
+to set a password before the account may be used.
+This may also be useful for creating administrative accounts.
+The final option causes
+.Xr pw 8
+to respond by printing a randomly generated password on stdout.
+This is the preferred and most secure option.
+.Xr Pw 8
+also provides a method of setting a specific password for the new
+user via a filehandle (command lines are not secure).
+.Pp
+Both
+.Ar reuseuids
+and
+.Ar reusegids
+determine the method by which new user and group id numbers are
+generated.
+A
+.Ql \&yes
+in this field will cause
+.Xr pw 8
+to search for the first unused user or group id within the allowed
+range, whereas a
+.Ql \&no
+will ensure that no other existing user or group id within the range
+is numerically lower than the new one generated, and therefore avoids
+reusing gaps in the user or group id sequence that are caused by
+previous user or group deletions.
+Note that if the default group is not specified using the
+.Ar defaultgroup
+keyword,
+.Xr pw 8
+will create a new group for the user and attempt to keep the new
+user's uid and gid the same.
+If the new user's uid is currently in use as a group id, then the next
+available group id is chosen instead.
+.Pp
+On NIS servers which maintain a separate passwd database to
+.Pa /etc/master.passwd ,
+this option allows the additional file to be concurrently updated
+as user records are added, modified or removed.
+If blank or set to 'no', no additional database is updated.
+An absolute pathname must be used.
+.Pp
+The
+.Ar skeleton
+keyword nominates a directory from which the contents of a user's
+new home directory is constructed.
+This is
+.Pa /usr/share/skel
+by default.
+.Xr Pw 8 Ns 's
+.Fl m
+option causes the user's home directory to be created and populated
+using the files contained in the
+.Ar skeleton
+directory.
+.Pp
+To send an initial email to new users, the
+.Ar newmail
+keyword may be used to specify a path name to a file containing
+the message body of the message to be sent.
+To avoid sending mail when accounts are created, leave this entry
+blank or specify
+.Ql \&no .
+.Pp
+The
+.Ar logfile
+option allows logging of password file modifications into the
+nominated log file.
+To avoid creating or adding to such a logfile, then leave this
+field blank or specify
+.Ql \&no .
+.Pp
+The
+.Ar home
+keyword is mandatory.
+This specifies the location of the directory in which all new user
+home directories are created.
+.Pp
+.Ar shellpath
+specifies a list of directories - separated by colons
+.Ql \&:
+- which contain the programs used by the login shells.
+.Pp
+The
+.Ar shells
+keyword specifies a list of programs available for use as login
+shells.
+This list is a comma-separated list of shell names which should
+not contain a path.
+These shells must exist in one of the directories nominated by
+.Ar shellpath .
+.Pp
+The
+.Ar defaultshell
+keyword nominates which shell program to use for new users when
+none is specified on the
+.Xr pw 8
+command line.
+.Pp
+The
+.Ar defaultgroup
+keyword defines the primary group (the group id number in the
+password file) used for new accounts.
+If left blank, or the word
+.Ql \&no
+is used, then each new user will have a corresponding group of
+their own created automatically.
+This is the recommended procedure for new users as it best secures each
+user's files against interference by other users of the system
+irrespective of the
+.Em umask
+normally used by the user.
+.Pp
+.Ar extragroups
+provides an automatic means of placing new users into groups within
+the
+.Pa /etc/groups
+file.
+This is useful where all users share some resources, and is preferable
+to placing users into the same primary group.
+The effect of this keyword can be overridden using the
+.Fl G
+option on the
+.Xr pw 8
+command line.
+.Pp
+The
+.Ar defaultclass
+field determines the login class (See
+.Xr login.conf 5 )
+that new users will be allocated unless overwritten by
+.Xr pw 8 .
+.Pp
+The
+.Ar minuid ,
+.Ar maxuid ,
+.Ar mingid ,
+.Ar maxgid
+keywords determines the allowed ranges of automatically allocated user
+and group id numbers.
+The default values for both user and group ids are 1000 and 32000 as
+minimum and maximum respectively.
+The user and group id's actually used when creating an account with
+.Xr pw 8
+may be overridden using the
+.Fl u
+and
+.Fl g
+command line options.
+.Pp
+The
+.Ar expire_days
+and
+.Ar password_days
+are used to automatically calculate the number of days from the date
+on which an account is created when the account will expire or the
+user will be forced to change the account's password.
+A value of
+.Ql \&0
+in either field will disable the corresponding (account or password)
+expiration date.
+.Sh LIMITS
+The maximum line length of
+.Pa /etc/pw.conf
+is 1024 characters.
+Longer lines will be skipped and treated
+as comments.

+.Os
+.Sh NAME
+.Nm pwd_mkdb
+.Nd "generate the password databases"
+.Sh SYNOPSIS
+.Nm
+.Op Fl C
+.Op Fl N
+.Op Fl p
+.Op Fl d Ar directory
+.Op Fl s Ar cachesize
+.Op Fl u Ar username
+.Ar file
+.Sh DESCRIPTION
+.Nm Pwd_mkdb
+creates
+.Xr db 3
+style secure and insecure databases for the specified file.
+These databases are then installed into
+.Pa /etc/spwd.db
+and
+.Pa /etc/pwd.db
+respectively.
+The file is installed into
+.Pa /etc/master.passwd .
+The file must be in the correct format (see
+.Xr passwd 5 ) .
+It is important to note that the format used in this system is
+different from the historic Version 7 style format.
+.Pp
+The options are as follows:
+.Bl -tag -width flag
+.It Fl C
+Check if the password file is in the correct format.
+Do not
+change, add, or remove any files.
+.It Fl N
+Tell
+.Nm
+to exit with an error if it cannot obtain a lock on the file.  By default,
+we block waiting for a lock on the source file.  The lock is held through
+the rebuilding of the database.
+.It Fl p
+Create a Version 7 style password file and install it into
+.Pa /etc/passwd .
+.It Fl d Ar directory
+Store databases into specified destination directory instead of
+.Pa /etc .
+.It Fl u Ar username
+Only update the record for the specified user.  Utilities that
+operate on a single user can use this option to avoid the
+overhead of rebuilding the entire database.
+.It Fl s Ar cachesize
+Specify in megabytes the size of the memory cache used by the
+hashing library.  On systems with a large user base, a small cache
+size can lead to prohibitively long database file rebuild times.
+As a rough guide, the memory usage of
+.Nm
+in megabytes will be a little bit more than twice the figure
+specified here.  The default is 2 megabytes.
+.El
+.Pp
+The two databases differ in that the secure version contains the user's
+encrypted password and the insecure version has an asterisk (``*'')
+.Pp
+The databases are used by the C library password routines (see
+.Xr getpwent 3 ) .
+.Pp
+.Nm Pwd_mkdb
+exits zero on success, non-zero on failure.
+.Sh ENVIRONMENT
+If the
+.Ev PW_SCAN_BIG_IDS
+environment variable is set,
+.Nm
+will suppress the warning messages that are
+normally generated for large user and group IDs.
+Such IDs can cause serious problems with software
+that makes assumptions about the values of IDs.
+.Sh FILES
+.Bl -tag -width Pa -compact
+.It Pa /etc/pwd.db
+The insecure password database file.
+.It Pa /etc/pwd.db.tmp
+A temporary file.
+.It Pa /etc/spwd.db
+The secure password database file.
+.It Pa /etc/spwd.db.tmp
+A temporary file.
+.It Pa /etc/master.passwd
+The current password file.
+.It Pa /etc/passwd
+A Version 7 format password file.
+.El
+.Sh BUGS
+Because of the necessity for atomic update of the password files,
+.Nm
+uses
+.Xr rename 2
+to install them.
+This, however, requires that the file specified on the command line live
+on the same filesystem as the
+.Pa /etc
+directory.
+.Pp
+There are the obvious races with multiple people running
+.Nm
+on different password files at the same time.
+The front-ends to
+.Nm ,
+.Xr chpass 1 ,
+.Xr passwd 1
+and
+.Xr vipw 8 ,
+handle the locking necessary to avoid this problem.
+.Sh COMPATIBILITY
+Previous versions of the system had a program similar to
+.Nm ,
+.Xr mkpasswd 8 ,
+which built
+.Xr dbm 3
+style databases for the password file but depended on the calling programs
+to install them.
+The program was renamed in order that previous users of the program
+not be surprised by the changes in functionality.
+.Sh SEE ALSO
+.Xr chpass 1 ,
+.Xr passwd 1 ,
+.Xr db 3 ,
+.Xr getpwent 3 ,
+.Xr passwd 5 ,

+.Sh NAME
+.Nm quot
+.Nd display disk space occupied by each user
+.Sh SYNOPSIS
+.Nm
+.Op Fl acfhknv
+.Op Ar filesystem ...
+.Sh DESCRIPTION
+.Nm Quot
+is used to gather statistics about the disk usage for each local user.
+.Pp
+The following options are available:
+.Bl -tag -width indent
+.It Fl a
+Include statistics for all mounted filesystems.
+.It Fl c
+Display three columns containing number of blocks per file,
+number of files in this category, and aggregate total of
+blocks in files with this or lower size.
+.It Fl f
+For each user, display count of files and space occupied.
+.It Fl h
+Estimate the number of blocks in each file based on its size.
+Despite that this doesn't give the correct results (it doesn't
+account for the holes in files), this option isn't any faster
+and thus is discouraged.
+.It Fl k
+Cause the numbers to be reported in kilobyte counts.
+By default, all sizes are reported in 512-byte block counts.
+.It Fl n
+Given a list of inodes (plus some optional data on each line)
+in the standard input, for each file print out the owner (plus
+the remainder of the input line). This is traditionally used
+in the pipe:
+.Bd -literal -offset indent
+.\" ncheck filesystem | sort +0n | quot -n filesystem
+ls -i | sed -e 's,^  *,,' | sort +0n | quot -n filesystem
+.Ed
+.Pp
+to get a report of files and their owners.
+.It Fl v
+In addition to the default output, display the number of files
+not accessed within 30, 60 and 90 days.
+.El
+.Sh ENVIRONMENT
+.Bl -tag -width BLOCKSIZE
+.It Ev BLOCKSIZE
+If the environment variable
+.Ev BLOCKSIZE
+is set, and the
+.Fl k
+option is not specified, the block counts will be displayed in units of that
+size block.
+.El
+.Sh BUGS
+.Xr ncheck
+(which would be a lot more useful than
+.Nm ls Fl i
+in the example above)
+does not exist in
+.Fx .
+.Sh SEE ALSO
+.Xr df 1 ,
+.Xr quota 1 ,
+.Xr getmntinfo 3 ,
+.Xr fstab 5 ,
+.Xr mount 8
+.Sh HISTORY
+This implementation of
+.Nm
+is by
+.An Wolfgang Solfrank
+/ TooLs GmbH.

+.Nm Quotaon
+announces to the system that disk quotas should be enabled on one or more
+filesystems.
+.Nm Quotaoff
+announces to the system that the specified
+filesystems should have any disk quotas turned off.
+The filesystems specified must have entries in
+.Pa /etc/fstab
+and be mounted.
+.Nm Quotaon
+expects each filesystem to have quota files named
+.Pa quota.user
+and
+.Pa quota.group
+which are located at the root of the associated filesystem.
+These defaults may be overridden in
+.Pa /etc/fstab .
+By default both user and group quotas are enabled.
+.Pp
+Available options:
+.Bl -tag -width indent
+.It Fl a
+If supplied in place of any filesystem names,
+.Nm Ns / Ns Nm quotaoff
+will enable/disable all the filesystems indicated in
+.Pa /etc/fstab
+to be read-write with disk quotas.
+By default only the types of quotas listed in
+.Pa /etc/fstab
+are enabled.
+.It Fl g

+.Nm
+.Op Fl adfsv
+.Op Fl t Ar directory
+.Op Ar interface
+.Sh DESCRIPTION
+.Nm
+services Reverse ARP requests on the Ethernet connected to
+.Ar interface .
+Upon receiving a request,
+.Nm
+maps the target hardware address to an IP address via its name, which
+must be present in both the
+.Xr ethers 5
+and
+.Xr hosts 5
+databases.
+If a host does not exist in both databases, the translation cannot
+proceed and a reply will not be sent.
+.Pp
+By default, a request is honored only if the server
+(i.e., the host that

+.Nm
+.Fl i Ar iface Fl Z Ar zero signal cache
+.Nm
+.Fl i Ar iface Fl C Ar display signal cache
+.Sh DESCRIPTION
+The
+.Nm
+command controls the operation of Raylink/Webgear wireless networking
+devices via the
+.Xr ray 4
+driver.
+Most of the parameters that can be changed relate to the
+IEEE 802.11 protocol which the card implements.
+This includes
+the station name, whether the station is operating in ad-hoc
+or infrastructure mode, and the network name of a service
+set to join - the BSS in ad-hoc mode or ESS if infrastructure mode is enabled.
+The
+.Nm
+command can also be used to view the current settings of these parameters
+and to dump out the values of the card's statistics counters.
+.Pp
+The
+.Ar iface
+argument given to
+.Nm
+should be the logical interface name associated with the Raylink/Webgear
+device (ray0, ray1, etc...).
+.Sh OPTIONS
+The options are as follows:
+.Bl -tag -width Fl
+.It Fl i Ar iface Op Fl o
+Display the current settings of the specified Raylink/Webgear interface.
+This retrieves the current card settings from the driver and prints them
+out.
+The results from this command are a snapshot of the card settings.
+Using the additional
+.Fl o
+flag will cause
+.Nm
+to print out the statistics counters instead of the card settings.
+.It Fl i Ar iface Fl t Ar tx rate
+Set the transmit rate of the specified interface.
+The
+NICs support a maximum transmit rate of 2Mbps.
+The following table shows the
+legal transmit rate settings and the corresponding transmit speeds:
+.Bl -column "TX rate " "NIC speed " -offset indent
+.Em "TX rate	NIC speed"
+1	Very Low (0.5Mbps)
+2	Low (1Mbps)
+3	Medium (1.5Mbps)
+4	High (2Mbps)
+.El
+.Pp
+The version 4 firmware may ignore this setting.
+Note, that the IEEE 802.11
+standard
+only allows 1Mbps or 2Mbps operation, and that the generally accepted
+reading of the IEEE 802.11 standard is that 2Mbps is only allowed in
+infrastructure mode.
+.It Fl i Ar iface Fl n Ar network name
+Set the name of the service set that this station wishes to
+join.
+The
+.Ar network name
+can be any text string up to 32 characters in length.
+The default name
+is the string "NETWORK_NAME" which should allow the station to connect to
+the default Webgear ad-hoc network.
+.It Fl i Ar iface Fl p Ar port type
+Set the
+.Ar port type
+for a specified interface.
+The legal values for
+.Ar port type
+are 0 (ad-hoc mode) and 1 (infrastructure mode).
+In ad-hoc mode, the station can
+communicate directly with any other stations within direct radio range
+(provided that they are also operating in ad-hoc mode).
+In inrastructure mode,
+hosts must associate with a service set controlled by an access point,
+that relays traffic between end stations.
+The default setting is 0
+(ad-hoc mode).
+.Pp
+When in ad-hoc mode the station will create a BSS with the network name
+specified by the
+.Fl n
+option if it cannot find an existing network of that name on the
+currently configured hopset (see the
+.Fl f
+option).
+.It Fl i Ar iface Fl m Ar mac address
+Set the station address for the specified interface.
+The
+.Ar mac address
+is specified as a series of six hexadecimal values separated by colons,
+e.g.: 00:60:1d:12:34:56.
+This programs the new address into the card
+and updates the interface as well.
+.It Fl i Ar iface Fl d Ar max_data_length
+Set the maximum transmit frame size for a specified interface.
+The
+.Ar max data length
+can be any number from 350 to 2304 or -1 to disable fragmentation.
+The default is -1.
+.It Fl i Ar iface Fl r Ar RTS threshold
+Set the RTS/CTS threshold for a given interface.
+This controls the
+number of bytes used for the RTS/CTS handshake boundary.
+The
+.Ar RTS threshold
+can be any value between -1 and 2047.
+The default is -1 (disable).
+.It Fl i Ar iface Fl f Ar hopset
+Set the radio hopset of a given interface.
+The
+.Ar hopset
+should be specified as a country code as shown in the table below.
+The
+hopset varies both the number of RF channels and their frequencies
+and is dependent on radio regulations specified
+by regional authorities.
+.Bl -column "Hopset ID " "Country " -offset indent
+.Em "Hopset ID	Country"
+1	USA
+2	Europe
+3	Japan
+4	Korea
+5	Spain
+6	France
+7	Israel
+8	Australia
+9	Japan Test
+.El
+.Pp
+Whilst the card can be programmed to work with any hopset it makes
+sense to use the hopset for your own region to avoid interference from
+and interfering with other users of the RF spectrum (in places like
+France this is the military).
+.Pp
+Note that all stations must be set to the same hopset in order to
+communicate.
+.It Fl i Ar iface Fl P Ar 0|1
+Enable or disable power management on a given interface.
+Enabling
+power management uses an alternating sleep/wake protocol to help
+conserve power on mobile stations, at the cost of some increased
+receive latency.
+Power management is off by default.
+.Pp
+Note that power
+management requires the cooperation of an access point in order to
+function; it is not functional in ad-hoc mode.
+Legal
+values for this parameter are 0 (off) and 1 (on).
+.It Fl i Ar iface Fl S Ar max_sleep_interval
+Specify the sleep interval to use when power management is enabled.
+The
+.Ar max_sleep_interval
+is specified in milliseconds.
+The default is 100.
+.It Fl i Ar iface Fl Z

+Display the cached signal strength information maintained by the
+.Nm ray
+driver.
+The driver retains information about signal strength and
+noise level for packets received from different hosts.
+For
+infrastructure networks the cache stores the signal strength of the
+access point.
+.Pp
+The driver also uses the cache to pick the best antenna when

+.Sh NAME
+.Nm rmt
+.Nd remote magtape protocol module
+.Sh SYNOPSIS
+.Nm
+.Sh DESCRIPTION
+.Nm Rmt
+is a program used by the remote dump and restore programs
+in manipulating a magnetic tape drive through an interprocess
+communication connection.
+.Nm Rmt
+is normally started up with an
+.Xr rexec 3
+or
+.Xr rcmd 3
+call.
+.Pp
+The
+.Nm
+program accepts requests specific to the manipulation of
+magnetic tapes, performs the commands, then responds with
+a status indication.  All responses are in
+.Tn ASCII
+and in
+one of two forms.
+Successful commands have responses of:
+.Bd -ragged -offset indent
+.Sm off
+.Sy A Ar number No \en
+.Sm on
+.Ed
+.Pp
+.Ar Number
+is an
+.Tn ASCII
+representation of a decimal number.
+Unsuccessful commands are responded to with:
+.Bd -ragged -offset indent
+.Sm off
+.Xo Sy E Ar error-number
+.No \en Ar error-message
+.No \en
+.Xc
+.Sm on
+.Ed
+.Pp
+.Ar Error-number
+is one of the possible error
+numbers described in
+.Xr intro 2
+and
+.Ar error-message
+is the corresponding error string as printed
+from a call to
+.Xr perror 3 .
+The protocol is comprised of the
+following commands, which are sent as indicated - no spaces are supplied
+between the command and its arguments, or between its arguments, and
+.Ql \en
+indicates that a newline should be supplied:
+.Bl -tag -width Ds
+.Sm off
+.It Xo Sy \&O Ar device
+.No \en Ar mode No \en
+.Xc
+.Sm on
+Open the specified
+.Ar device
+using the indicated
+.Ar mode .
+.Ar Device
+is a full pathname and
+.Ar mode
+is an
+.Tn ASCII
+representation of a decimal
+number suitable for passing to
+.Xr open 2 .
+If a device had already been opened, it is
+closed before a new open is performed.
+.Sm off
+.It Xo Sy C Ar device No \en
+.Xc
+.Sm on
+Close the currently open device.  The
+.Ar device
+specified is ignored.
+.Sm off
+.It Xo Sy L
+.Ar whence No \en
+.Ar offset No \en
+.Xc
+.Sm on
+Perform an
+.Xr lseek 2
+operation using the specified parameters.
+The response value is that returned from the
+.Xr lseek
+call.
+.Sm off
+.It Sy W Ar count No \en
+.Sm on
+Write data onto the open device.
+.Nm Rmt
+reads
+.Ar count
+bytes from the connection, aborting if
+a premature end-of-file is encountered.
+The response value is that returned from
+the
+.Xr write 2
+call.
+.Sm off
+.It Sy R Ar count No \en
+.Sm on
+Read
+.Ar count
+bytes of data from the open device.
+If
+.Ar count
+exceeds the size of the data buffer (10 kilobytes), it is
+truncated to the data buffer size.
+.Nm Rmt
+then performs the requested
+.Xr read 2
+and responds with
+.Sm off
+.Sy A Ar count-read No \en
+.Sm on
+if the read was
+successful; otherwise an error in the
+standard format is returned.  If the read
+was successful, the data read is then sent.
+.Sm off
+.It Xo Sy I Ar operation
+.No \en Ar count No \en
+.Xc
+.Sm on
+Perform a
+.Dv MTIOCOP
+.Xr ioctl 2
+command using the specified parameters.
+The parameters are interpreted as the
+.Tn ASCII
+representations of the decimal values
+to place in the
+.Ar mt_op
+and
+.Ar mt_count
+fields of the structure used in the
+.Xr ioctl 2
+call.  The return value is the
+.Ar count
+parameter when the operation is successful.
+.It Sy S
+Return the status of the open device, as
+obtained with a
+.Dv MTIOCGET
+.Xr ioctl 2
+call.  If the operation was successful,
+an ``ack'' is sent with the size of the
+status buffer, then the status buffer is
+sent (in binary).
+.El
+.Pp
+Any other command causes
+.Nm
+to exit.
+.Sh DIAGNOSTICS
+All responses are of the form described above.
+.Sh SEE ALSO
+.Xr rcmd 3 ,
+.Xr rexec 3 ,
+.Xr mtio 4 ,
+.Xr rdump 8 ,
+.Xr rrestore 8
+.Sh BUGS
+People should be discouraged from using this for a remote
+file access protocol.
+.Sh HISTORY
+The
+.Nm
+command appeared in
+.Bx 4.2 .

+ *		conversation with the remote portmapper to get the
+ *		port number.  Since a given client is quite likely
+ *		to make several locking requests in succession, it is
+ *		desirable to cache the created CLIENT*.
+ *
+ *		Since we are using UDP rather than TCP, there is no cost
+ *		to the remote system in keeping these cached indefinitely.
+ *		Unfortunately there is a snag: if the remote system
+ *		reboots, the cached portmapper results will be invalid,
+ *		and we will never detect this since all of the xxx_msg()
+ *		calls return no result - we just fire off a udp packet
+ *		and hope for the best.
+ *
+ *		We solve this by discarding cached values after two
+ *		minutes, regardless of whether they have been used
+ *		in the meanwhile (since a bad one might have been used
+ *		plenty of times, as the host keeps retrying the request
+ *		and we keep sending the reply back to the wrong port).
+ *
+ *		Given that the entries will always expire in the order
+ *		that they were created, there is no point in a LRU
+ *		algorithm for when the cache gets full - entries are
+ *		always re-used in sequence.

+.Os
+.Sh NAME
+.Nm rpc.lockd
+.Nd NFS file locking daemon
+.Sh SYNOPSIS
+.Nm
+.Op Fl d Ar debug_level
+.Op Fl g Ar grace period
+.Sh DESCRIPTION
+The
+.Nm
+daemon provides monitored and unmonitored file and record locking services
+in an NFS environment.
+To monitor the status of hosts requesting locks,
+the locking daemon typically operates in conjunction
+with
+.Xr rpc.statd 8 .
+.Pp
+Options and operands available for
+.Nm :
+.Bl -tag -width indent
+.It Fl d
+The
+.Fl d
+option causes debugging information to be written to syslog, recording
+all RPC transactions to the daemon.
+These messages are logged with level
+.Dv LOG_DEBUG
+and facility
+.Dv LOG_DAEMON .
+Specifying a
+.Ar debug_level
+of 1 results
+in the generation of one log line per protocol operation.
+Higher
+debug levels can be specified, causing display of operation arguments
+and internal operations of the daemon.
+.It Fl g
+The
+.Fl g
+option allow to specify the
+.Ar grace period ,
+in seconds.
+During the grace period
+.Nm
+only accepts requests from hosts which are reinitialising locks which
+existed before the server restart.
+Default is 30 seconds.
+.El
+.Pp
+Error conditions are logged to syslog, irrespective of the debug level,
+using log level
+.Dv LOG_ERR
+and facility
+.Dv LOG_DAEMON .
+.Pp
+The
+.Nm
+daemon must NOT be invoked by
+.Xr inetd 8
+because the protocol assumes that the daemon will run from system start time.
+Instead, it should be configured in
+.Xr rc.conf 5
+to run at system startup.
+.Sh FILES
+.Bl -tag -width /usr/include/rpcsvc/nlm_prot.x -compact
+.It Pa /usr/include/rpcsvc/nlm_prot.x
+RPC protocol specification for the network lock manager protocol.
+.El
+.Sh SEE ALSO
+.Xr syslog 3 ,
+.Xr rc.conf 5 ,
+.Xr rpc.statd 8
+.Sh BUGS
+The current implementation serialises locks requests that could be shared.
+.Sh STANDARDS
+The implementation is based on the specification in
+.Rs
+.%B "X/Open CAE Specification C218"
+.%T "Protocols for X/Open PC Interworking: XNFS, Issue 4"
+.%O ISBN 1 872630 66 9

+.Sh HISTORY
+A version of
+.Nm
+appeared in
+.Tn SunOS

+.Os
+.Sh NAME
+.Nm rpc.statd
+.Nd host status monitoring daemon
+.Sh SYNOPSIS
+.Nm
+.Op Fl d
+.Sh DESCRIPTION
+.Nm Rpc.statd
+is a daemon which co-operates with rpc.statd daemons on other hosts to provide
+a status monitoring service.  The daemon accepts requests from
+programs running on the local host (typically,
+.Xr rpc.lockd 8 ,
+the NFS file locking daemon) to monitor the status of specified
+hosts.  If a monitored host crashes and restarts, the remote daemon will
+notify the local daemon, which in turn will notify the local program(s)
+which requested the monitoring service.  Conversely, if this host crashes
+and re-starts, when the
+.Nm
+re-starts, it will notify all of the hosts which were being monitored
+at the time of the crash.
+.Pp
+The following option is available:
+.Bl -tag -width indent
+.It Fl d
+Cause debugging information to be written to syslog, recording
+all RPC transactions to the daemon.  These messages are logged with level
+LOG_DEBUG and facility LOG_DAEMON.  Error conditions are logged irrespective
+of this option, using level LOG_ERR.
+.El
+.Pp
+The
+.Nm
+daemon must NOT be invoked by
+.Xr inetd 8
+because the protocol assumes that the daemon will run from system start time.
+Instead, it should be run from
+.Xr rc 8
+after the network has been started.
+.Sh FILES
+.Bl -tag -width /usr/include/rpcsvc/sm_inter.x -compact
+.It Pa /var/db/statd.status
+non-volatile record of currently monitored hosts.
+.It Pa /usr/include/rpcsvc/sm_inter.x
+RPC protocol specification used by local applications to register monitoring requests.
+.El
+.Sh SEE ALSO
+.Xr syslog 3 ,
+.Xr rc 8 ,
+.Xr rpc.lockd 8
+.Sh BUGS
+There is no means for the daemon to tell when a monitored host has
+disappeared permanently (eg. catastrophic hardware failure), as opposed
+to transient failure of the host or an intermediate router.  At present,
+it will re-try notification attempts at frequent intervals for 10 minutes,
+then hourly, and finally gives up after 24 hours.
+.Pp
+The protocol requires that symmetric monitor requests are made to both
+the local and remote daemon in order to establish a monitored relationship.
+This is convenient for the NFS locking protocol, but probably reduces the
+usefulness of the monitoring system for other applications.
+.Pp
+The current implementation uses more than 1Kbyte per monitored host in
+the status file (and also in VM).  This may be inefficient for NFS servers
+with large numbers of clients.
+.Sh STANDARDS
+The implementation is based on the specification in X/Open CAE Specification

+  Data structures for recording monitored hosts
+
+  The information held by the status monitor comprises a list of hosts
+  that we have been asked to monitor, and, associated with each monitored
+  host, one or more clients to be called back if the monitored host crashes.
+
+  The list of monitored hosts must be retained over a crash, so that upon
+  re-boot we can call the SM_NOTIFY procedure in all those hosts so as to
+  cause them to start recovery processing.  On the other hand, the client
+  call-backs are not required to be preserved: they are assumed (in the
+  protocol design) to be local processes which will have crashed when
+  we did, and so are discarded on restart.
+
+  We handle this by keeping the list of monitored hosts in a file
+  (/var/statd.state) which is mmap()ed and whose format is described
+  by the typedef FileLayout.  The lists of client callbacks are chained
+  off this structure, but are held in normal memory and so will be
+  lost after a re-boot.  Hence the actual values of MonList * pointers
+  in the copy on disc have no significance, but their NULL/non-NULL
+  status indicates whether this host is actually being monitored or if it

+.Dt RPC.UMNTALL 8
+.Os
+.Sh NAME
+.Nm rpc.umntall
+.Nd notify NFS servers about unmounted NFS filesystems
+.Sh SYNOPSIS
+.Nm
+.Op Fl e Ar expire
+.Op Fl h Ar host
+.Op Fl k
+.Op Fl p Ar remotepath
+.Op Fl v
+.Sh DESCRIPTION
+.Nm
+is as command as proposed in the
+.Tn NFS
+RPC specification; see
+.Rs
+.%T "NFS Version 3 Protocol Specification"
+.%O "RFC 1813, Appendix I"
+.Re
+It uses remote procedure calls to remove mount entries from
+.Pa /var/db/mountdtab
+on the remote NFS server.
+It is called automatically
+without any parameters during startup and shutdown of
+the system.
+This ensures that
+.Xr showmount 8
+does not display old and expired entries.
+The
+.Nm
+command
+is only needed on client side, where
+.Xr mount_nfs 8
+adds a mount entry with the current date to
+.Pa /var/db/mounttab ,
+and
+.Xr umount 8
+removes the entry again.
+The
+.Nm
+command
+cares about all remaining entries in this table which result from crashes
+or unproper shutdowns.
+.Pp
+The options are as follows:
+.Bl -tag -width indentxxx
+.It Fl e Ar expire
+All entries which are not actually mounted or older than
+.Ar expire
+(seconds) are removed from
+.Pa /var/db/mounttab .
+This may be the case
+for DNS changes or long out of service periods.
+Default expire time
+is 86400 seconds (one day).
+.It Fl h Ar host
+Only remove the specific hostname.
+Send a UMNTALL RPC to the NFS server.
+.It Fl k
+Keep entries for existing NFS filesystems.
+Compare the NFS filesystems from
+the mounttab against the kernel mountlist and do not send the RPC to
+existing mount entries.
+Useful during startup of the system.
+It may be
+possible that there are already mounted NFS filesystems, so calling
+RPC UMOUNT isn't a good idea.
+This is the case if the user has rebooted
+to 'single user mode' and starts up the system again.
+.It Fl p Ar path
+Only remove the specific mount-path.
+Send a UMOUNT RPC to the NFS server.
+This option implies the
+.Fl host
+option.
+.It Fl v
+Verbose, additional information is printed for each processed mounttab
+entry.
+.El
+.Sh FILES
+.Bl -tag -width /var/db/mounttab -compact
+.It Pa /var/db/mounttab
+mounted nfs-filesystems
+.El
+.Sh HISTORY
+The
+.Nm
+command first appeared in
+.Fx 4.0 .
+.Sh SEE ALSO
+.Xr mountd 8 ,
+.Xr mount_nfs 8 ,
+.Xr umount 8

+.Sh NAME
+.Nm rpc.yppasswdd
+.Nd "server for updating NIS passwords"
+.Sh SYNOPSIS
+.Nm
+.Op Fl t Ar master.passwd template file
+.Op Fl d Ar default domain
+.Op Fl p Ar path
+.Op Fl s
+.Op Fl f
+.Op Fl a
+.Op Fl m
+.Op Fl i
+.Op Fl v
+.Op Fl u
+.Op Fl h
+.Sh DESCRIPTION
+The
+.Nm
+daemon allows users to change their NIS passwords and certain
+other information using the
+.Xr yppasswd 1
+and
+.Xr ypchpass 1
+commands.
+.Nm Rpc.yppasswdd
+is an RPC-based server that accepts incoming password change requests,
+authenticates them, places the updated information in the
+.Pa /var/yp/master.passwd
+template file and then updates the NIS
+.Pa master.passwd
+and
+.Pa passwd
+maps.
+.Pp
+The
+.Nm
+server allows a normal NIS user to change
+his or her NIS password, full name (also
+known as 'GECOS' field) or shell.
+These updates are typically done using
+the
+.Xr yppasswd 1 ,
+.Xr ypchfn 1 ,
+.Xr ypchsh 1 ,
+or
+.Xr ypchpass 1
+commands.
+(Some administrators don't want users to be able to change their
+full name information or shells; the server can be invoked with option flags
+that disallow such changes.)
+When the server receives an update request,
+it compares the address of the client making the request against the
+.Pa securenets
+rules outlined in
+.Pa /var/yp/securenets .
+(See the
+.Xr ypserv 8
+manual page for more information on securenets; the
+.Nm
+server uses the same access control mechanism as
+.Xr ypserv 8 . )
+.Pp
+The server then
+checks the 'old' password supplied by the user to make sure it's
+valid, then performs some sanity checks on the updated information (these
+include checking for embedded control characters, colons or invalid shells).
+Once it is satisfied that the update request is valid, the server modifies
+the template password file (the default is
+.Pa /var/yp/master.passwd )
+and then runs the
+.Pa /usr/libexec/yppwupdate
+script to rebuild the NIS maps.
+(This script has two arguments passed
+to it: the absolute pathname of the password template that was modified
+and the name of the domain that is to be updated.
+These in turn are
+passed to
+.Pa /var/yp/Makefile ) .
+.Pp
+The
+.Fx
+version of
+.Nm
+also allows the super-user on the NIS master server to perform more
+sophisticated updates on the NIS passwd maps.
+The super-user can modify
+any field in any user's master.passwd entry in any domain, and can
+do so without knowing the user's existing NIS password (when the server
+receives a request from the super-user, the password authentication
+check is bypassed). Furthermore, if the server is invoked with the
+.Fl a
+flag, the super-user can even add new entries to the maps using
+.Xr ypchpass 1 .
+Again, this only applies to the super-user on the NIS
+master server: none of these special functions can be peformed over
+the network.
+.Pp
+The
+.Nm
+daemon can only be run on a machine that is an NIS master server.
+.Sh OPTIONS
+The following options are available:
+.Bl -tag -width indent
+.It Fl t Ar master.passwd template file
+By default,
+.Nm
+assumes that the template file used to generates the
+.Pa master.passwd
+and
+.Pa passwd
+maps for the default domain is called
+.Pa /var/yp/master.passwd .
+This default can be overridden by specifying an alternate file name
+with the
+.Fl t
+flag.
+.Pp
+Note: if the template file specified with this flag is
+.Pa /etc/master.passwd ,
+.Nm
+will also automatically invoke
+.Xr pwd_mkdb 8
+to rebuild the local password databases in addition to the NIS
+maps.
+.It Fl d Ar domain
+The
+.Nm
+server can support multiple domains, however it must
+choose one domain as a default.
+It will try to use the system default domain name as set by the
+.Xr domainname 1
+command for this default.
+However,
+if the system domain name is not
+set, a default domain must be specified on
+the command line.
+If the system default domain is set,
+then this option can be used to override it.
+.It Fl p Ar path
+This option can be used to override the default path to
+the location of the NIS
+map databases.
+The compiled-in default path is
+.Pa /var/yp .
+.It Fl s
+Disallow changing of shell information.
+.It Fl f
+Disallow changing of full name ('GECOS') information.
+.It Fl a
+Allow additions to be made to the NIS passwd databases.
+The super-user on the
+NIS master server is permitted to use the
+.Xr ypchpass 1
+command to perform unrestricted modifications to any field in a user's
+.Pa master.passwd
+map entry.
+When
+.Nm
+is started with this flag, it will also allow the super-user to add new
+records to the NIS passwd maps, just as is possible when using
+.Xr chpass 1
+to modify the local password database.
+.It Fl m
+Turn on multi-domain mode.
+Even though
+.Xr ypserv 8
+can handle several simultaneous domains, most implementations of
+.Nm
+can only operate on a single NIS domain, which is generally the same as
+the system default domain of the NIS master server.
+The
+.Fx
+.Nm
+attempts to overcome this problem in spite of the inherent limitations
+of the
+.Pa yppasswd
+protocol, which does not allow for a
+.Pa domain
+argument in client requests.
+In multi-domain mode,
+.Nm
+will search through all the passwd maps of all the domains it
+can find under
+.Pa /var/yp
+until it finds an entry that matches the user information specified in
+a given update request.
+(Matches are determined by checking the username,
+UID and GID fields.)
+The matched entry and corresponding domain are then
+used for the update.
+.Pp
+Note that in order for multi-domain mode to work, there have to be
+separate template files for each domain.
+For example, if a server
+supports three domains,
+.Pa foo ,
+.Pa bar ,
+and
+.Pa baz ,
+there should be three separate master.passwd template files called
+.Pa /var/yp/foo/master.passwd ,
+.Pa /var/yp/bar/master.passwd ,
+and
+.Pa /var/yp/baz/master.passwd .
+If
+.Pa foo
+happens to be the system default domain, then its template file can
+be either
+.Pa /var/yp/foo/master.passwd
+or
+.Pa /var/yp/master.passwd .
+The server will check for the latter file first and then use the former
+if it can't find it.
+.Pp
+Multi-domain mode is off by default since it can fail if there are
+duplicate or near-duplicate user entries in different domains.
+The server
+will abort an update request if it finds more than one user entry that
+matches its search criteria.
+Even so, paranoid administrators
+may wish to leave multi-domain mode disabled.
+.It Fl i
+If
+.Nm
+is invoked with this flag, it will perform map updates in place.
+This
+means that instead of just modifying the password template file and
+starting a map update, the server will modify the map databases
+directly.
+This is useful when the password maps are large: if, for
+example, the password database has tens of thousands of entries, it
+can take several minutes for a map update to complete.
+Updating the
+maps in place reduces this time to a few seconds.
+.It Fl v
+Turn on verbose logging mode.
+The server normally only logs messages
+using the
+.Xr syslog 3
+facility when it encounters an error condition, or when processing
+updates for the super-user on the NIS master server.
+Running the server
+with the
+.Fl v
+flag will cause it to log informational messages for all updates.
+.It Fl u
+Many commercial
+.Xr yppasswd 1
+clients do not use a reserved port when sending requests to
+.Nm .
+This is either because the
+.Xr yppasswd 1
+program is not installed set-uid root, or because the RPC
+implementation does not place any emphasis on binding to reserved
+ports when establishing client connections for the super-user.
+By default,
+.Nm
+expects to receive requests from clients using reserved ports; requests
+received from non-privileged ports are rejected.
+Unfortunately, this
+behavior prevents any client systems that to not use privileged
+ports from successfully submitting password updates.
+Specifying
+the
+.Fl u
+flag to
+.Nm
+disables the privileged port check so that it will work with
+.Xr yppasswd 1
+clients that don't use privileged ports.
+This reduces security to
+a certain small degree, but it might be necessary in cases where it
+is not possible to change the client behavior.

+.Xr ypxfr 8
+.Sh BUGS
+As listed in the yppasswd.x protocol definition, the YPPASSWDPROC_UPDATE
+procedure takes two arguments: a V7-style passwd structure containing
+updated user information and the user's existing unencrypted (cleartext)
+password.
+Since
+.Nm
+is supposed to handle update requests from remote NIS client machines,
+this means that
+.Xr yppasswd 1
+and similar client programs will in fact be transmitting users' cleartext
+passwords over the network.
+.Pp
+This is not a problem for password updates since the plaintext password
+sent with the update will no longer be valid once the new encrypted password
+is put into place, but if the user is only updating his or her 'GECOS'
+information or shell, then the cleartext password sent with the update
+will still be valid once the update is completed.
+If the network is
+insecure, this cleartext password could be intercepted and used to
+gain unauthorized access to the user's account.

+.Dt RPC.YPXFRD 8
+.Os
+.Sh NAME
+.Nm rpc.ypxfrd
+.Nd "NIS map transfer server"
+.Sh SYNOPSIS
+.Nm
+.Op Fl p Ar path
+.Sh DESCRIPTION
+The
+.Nm
+daemon is used to speed up the distribtion of very large NIS maps
+from NIS master to NIS slave servers.
+The normal method for transfering
+maps involves several steps:
+.Bl -bullet -offset indent
+.It
+The master server calls
+.Xr yppush 8
+to inform the slave servers to start a transfer.
+.It
+The slave servers invoke
+.Xr ypxfr 8 ,
+which reads the entire contents of a map from the master server
+using the yp_all() function.
+.It
+The
+.Xr ypxfr 8
+program then creates a new map database file by using the
+.Xr db 3
+library hash method to store the data that it receives from the server.
+.It
+When all the data has been retrieved,
+.Xr ypxfr 8
+moves the new file into place and sends
+.Xr ypserv 8
+on the local machine a YPPROC_CLEAR to tell it to refresh its
+database handles.
+.El
+.Pp
+This process can take several minutes when there are very large
+maps involved.
+For example: a passwd database with several tens of
+thousands of entries can consume several megabytes of disk space,
+and it can take the
+.Xr db 3
+library package a long time to sort and store all the records
+in a hash database.
+Consider also that there are two sets of map
+files:
+.Pa master.passwd.by{name,uid}
+and
+.Pa passwd.by{name,uid} .
+.Pp
+The
+.Nm
+server speeds up the transfer process by allowing NIS slave servers to
+simply copy the master server's map files rather than building their
+own from scratch.
+Simply put,
+.Nm
+implements an RPC-based file transfer protocol.
+Transfering even
+a multi-megabyte file in this fashion takes only a few seconds compared
+to the several minutes it would take even a reasonably fast slave server
+to build a new map from scratch.
+.Pp
+The
+.Nm
+server uses the same access restriction mechanism as
+.Xr ypserv 8 .
+This means that slave servers will only be permitted to transfer
+files if the rules in the
+.Xr securenets 5
+database permit it.
+Furthermore, only slave servers using reserved
+ports will be allowed to transfer the
+.Pa master.passwd
+maps.
+.Sh OPTIONS
+The following option is available:
+.Bl -tag -width indent
+.It Fl p Ar path
+This option can be used to override the default path to
+the location of the NIS
+map databases.
+The compiled-in default path is
+.Pa /var/yp .
+.El
+.Sh FILES
+.Bl -tag -width Pa -compact
+.It Pa /var/yp/[domainname]/[maps]
+The NIS maps for a particular NIS domain.
+.El
+.Sh SEE ALSO
+.Xr yp 8 ,
+.Xr yppush 8 ,
+.Xr ypserv 8 ,
+.Xr ypxfr 8
+.Sh BUGS
+The
+.Fx
+.Nm ypxfrd
+protocol is not compatible with that used by SunOS.
+This is unfortunate
+but unavoidable: Sun's protocol is not freely available, and even if it
+were it would probably not be useful since the SunOS NIS v2 implementation
+uses the original ndbm package for its map databases whereas the
+.Fx
+implementation uses Berkeley DB.
+These two packages use vastly different
+file formats.
+Furthermore, ndbm is byte-order sensitive and not very
+smart about it, meaning that am ndbm database created on a big endian
+system can't be read on a little endian system.

+program numbers into
+universal addresses.
+It must be running on the host to be able to make
+.Tn RPC
+calls
+on a server on that machine.
+.Pp
+When an
+.Tn RPC
+service is started,
+it tells
+.Nm
+the address at which it is listening,
+and the
+.Tn RPC
+program numbers it is prepared to serve.
+When a client wishes to make an
+.Tn RPC
+call to a given program number,
+it first contacts
+.Nm
+on the server machine to determine
+the address where
+.Tn RPC
+requests should be sent.
+.Pp
+.Nm
+should be started before any other RPC service.
+Normally, standard
+.Tn RPC
+servers are started by port monitors, so
+.Nm
+must be started before port monitors are invoked.
+.Pp
+When
+.Nm
+is started, it checks that certain name-to-address
+translation-calls function correctly.
+If they fail, the network configuration databases may be corrupt.
+Since
+.Tn RPC
+services cannot function correctly in this situation,
+.Nm
+reports the condition and terminates.
+.Pp
+.Nm
+can only be started by the super-user.

+.Fl c Ar conf_file | Fl s
+.Oc
+.Sh DESCRIPTION
+.Nm
+transmits router renumbering request packets,
+to renumber the routers in the site network.
+.Pp
+On KAME-based systems,
+router renumbering requests are received and processed by
+.Xr rtadvd 8 .
+For other systems, refer to relevant documents.
+.Pp
+The program will daemonize itself on invocation.
+It reads configuration information from standard input if
+.Fl s
+is specified, or from
+.Ar conf_file
+if
+.Fl c Ar conf_file
+is specified.
+.Pp
+The contents of configuration information are described in
+.Xr rrenumd.conf 5 .
+.Pp
+After successful configuration,
+.Nm
+sends router renumbering
+messages periodically to configured destinations.
+Messages contain prefixes configured to be renumbered.
+.Bl -tag -width indent
+.\"
+.It Fl d
+Debug mode.
+.It Fl f
+Foreground mode.
+Do not become daemon.
+.It Fl s
+Script mode.
+Configuration information is obtained from standard input.
+.It Fl c Ar conf_file
+Specify a configuration file where configuration information is kept.
+.El
+.Sh RETURN VALUES
+The program exits with 0 on success, and non-zero on failures.

+.Nm rrenumd.conf
+.Nd configuration file for router renumbering daemon
+.\"
+.Sh DESCRIPTION
+The rrenumd config file describes how the router renumbering packet
+must be constructed and to which destinations it should be sent.
+This file consists of a sequence of statements terminated by a semi-colon (`;').
+Statements are composed of tokens
+separated by white space, which can be any combination of blanks, tabs
+and newlines.
+This structure simplifies identification of
+the parts of the configuration associated with each other.
+Lines beginning with
+.Ql #
+are comments.
+.\"
+.Sh Meta Syntax
+Keywords and special characters that the parser expects exactly are
+displayed using the
+.Ic bold
+font.
+Parameters are specifying with
+.Ar underline .
+Parameters shown in
+square brackets (`[' and `]') are used to show optional
+keywords and parameters.
+The vertical bar (`|') is used to indicate
+between a choice of optional parameters.
+Curly braces (`{' and
+`}') are used to group keywords and parameters when necessary.
+.\"
+.Sh Interface specification
+There are some statements that may or have to specify interface.
+Interfaces are specified in the form of "name unit", such as
+.Ar lo0
+and
+.Ar ep1 .
+.\"

+.Sh NAME
+.Nm rtadvd
+.Nd router advertisement daemon
+.Sh SYNOPSIS
+.Nm
+.Op Fl dDfMRs
+.Op Fl c Ar configfile
+.Ar interface ...
+.Sh DESCRIPTION
+.Nm
+sends router advertisement packets to the specified
+.Ar interfaces .
+.Pp
+The program will daemonize itself on invocation.
+It will then send router advertisement packets periodically, as well
+as in response to router solicitation messages sent by end hosts.
+.Pp
+Router advertisements can be configured on a per-interface basis, as
+described in
+.Xr rtadvd.conf 5 .
+.Pp
+If there is no configuration file entry for an interface,
+or if the configuration file does not exist altogether,
+.Nm
+sets all the parameters to their default values.
+In particular,
+.Nm
+reads all the interface routes from the routing table and advertises
+them as on-link prefixes.
+.Pp
+.Nm
+also watches the routing table.
+If an interface direct route is
+added on an advertising interface and no static prefixes are
+specified by the configuration file,
+.Nm
+adds the corresponding prefix to its advertising list.
+.Pp
+Similarly, when an interface direct route is deleted,
+.Nm
+will start advertising the prefixes with zero valid and preferred
+lifetimes to help the receiving hosts switch to a new prefix when
+renumbering.
+Note, however, that the zero valid lifetime cannot invalidate the
+autoconfigured addresses at a receiving host immediately.
+According to the specification, the host will retain the address
+for a certain period, which will typically be two hours.
+The zero lifetimes rather intend to make the address deprecated,
+indicating that a new non-deprecated address should be used as the
+source address of a new connection.
+This behavior will last for two hours.
+Then
+.Nm
+will completely remove the prefix from the advertising list,
+and succeeding advertisements will not contain the prefix information.
+.Pp
+Moreover, if the status of an advertising interface changes,
+.Nm
+will start or stop sending router advertisements according
+to the latest status.
+.Pp
+The
+.Fl s
+option may be used to disable this behavior;
+.Nm
+will not watch the routing table and the whole functionality described
+above will be suppressed.
+.Pp
+Basically, hosts MUST NOT send Router Advertisement messages at any
+time (RFC 2461, Section 6.2.3).
+However, it would sometimes be useful to allow hosts to advertise some
+parameters such as prefix information and link MTU.
+Thus,
+.Nm
+can be invoked if router lifetime is explicitly set zero on every
+advertising interface.
+.Pp
+The command line options are:
+.Bl -tag -width indent
+.\"
+.It Fl c
+Specify an alternate location,
+.Ar configfile ,
+for the configuration file.
+By default,
+.Pa /etc/rtadvd.conf
+is used.
+.It Fl d
+Print debugging information.
+.It Fl D
+Even more debugging information is printed.
+.It Fl f
+Foreground mode (useful when debugging).
+.It Fl M
+Specify an interface to join the all-routers site-local multicast group.
+By default,
+.Nm
+tries to join the first advertising interface appeared in the command
+line.
+This option has meaning only with the
+.Fl R
+option, which enables routing renumbering protocol support.
+.\".It Fl m
+.\"Enables mobile IPv6 support.
+.\"This changes the content of router advertisement option, as well as
+.\"permitted configuration directives.
+.It Fl R
+Accept router renumbering requests.
+If you enable it, certain IPsec setup is suggested for security reasons.
+On KAME-based systems,
+.Xr rrenumd 8
+generates router renumbering request packets.
+This option is currently disabled, and is ignored by
+.Nm
+with a warning message.
+.It Fl s
+Do not add or delete prefixes dynamically.
+Only statically configured prefixes, if any, will be advertised.
+.El
+.Pp
+Upon receipt of signal
+.Dv SIGUSR1 ,
+.Nm
+will dump the current internal state into
+.Pa /var/run/rtadvd.dump .
+.Pp
+Use
+.Dv SIGTERM
+to kill
+.Nm
+gracefully.
+In this case,
+.Nm
+will transmit router advertisement with router lifetime 0
+to all the interfaces
+(in accordance with RFC2461 6.2.5).
+.Sh DIAGNOSTICS
+.Ex -std
+.Sh FILES
+.Bl -tag -width Pa -compact
+.It Pa /etc/rtadvd.conf
+The default configuration file.
+.It Pa /var/run/rtadvd.pid
+contains the pid of the currently running
+.Nm .
+.It Pa /var/run/rtadvd.dump
+in which
+.Nm
+dumps its internal state.
+.El
+.Sh SEE ALSO
+.Xr rtadvd.conf 5 ,
+.Xr rrenumd 8 ,
+.Xr rtsol 8
+.Sh HISTORY
+The
+.Nm
+command first appeared in WIDE Hydrangea IPv6 protocol stack kit.
+.Sh CAVEAT
+There used to be some text that recommended users not to let
+.Nm
+advertise Router Advertisement messages on an upstream link to avoid
+undesirable
+.Xr icmp6 4
+redirect messages.
+However, based on the later discussion in the IETF ipng working group,
+all routers should rather advertise the messages regardless of
+the network topology, in order to ensure reachability.

+.Sh NAME
+.Nm rtadvd.conf
+.Nd config file for router advertisement daemon
+.Sh DESCRIPTION
+This file describes how the router advertisement packets must be constructed
+for each of the interfaces.
+.Pp
+As described in
+.Xr rtadvd 8 ,
+you do not have to set this configuration file up at all,
+unless you need some special configurations.
+You may even omit the file as a whole.
+In such cases, the
+.Nm rtadvd
+daemon will automatically configure itself using default values
+specified in the specification.
+.Pp
+It obeys the famous
+.Xr termcap 5
+file format.
+Each line in the file describes a network interface.
+Fields are separated by a colon
+.Pq Sq \&: ,
+and each field contains one capability description.
+Lines may be concatenated by the
+.Sq \e
+character.
+The comment marker is the
+.Sq \&#
+character.
+.Sh CAPABILITIES
+Capabilities describe the value to be filled into ICMPv6 router
+advertisement messages and to control
+.Xr rtadvd 8
+behavior.
+Therefore, you are encouraged to read IETF neighbor discovery documents
+if you would like to modify the sample configuration file.
+.Pp
+Note that almost all items have default values.
+If you omit an item, the default value of the item will be used.
+.Pp
+There are two items which control the interval of sending router advertisements.
+These items can be omitted, then
+.Nm rtadvd
+will use the default values.
+.Bl -tag -width indent
+.It Cm \&maxinterval
+(num) The maximum time allowed between sending unsolicited
+multicast router advertisements
+(unit: seconds).
+The default value is 600.
+Its value must be no less than 4 seconds
+and no greater than 1800 seconds.
+.It Cm \&mininterval
+(num) The minimum time allowed between sending unsolicited multicast
+router advertisements
+(unit: seconds).
+The default value is the one third of value of
+.Cm maxinterval .
+Its value must be no less than 3 seconds and no greater than .75 *
+the value of
+.Cm maxinterval .
+.El
+.Pp
+The following items are for ICMPv6 router advertisement message
+header.
+These items can be omitted, then
+.Nm rtadvd
+will use the default values.
+.Bl -tag -width indent
+.It Cm \&chlim
+(num) The value for Cur Hop Limit field.
+The default value is 64.
+.It Cm \&raflags
+(num) Flags field in router advertisement message header.
+Bit 7
+.Pq Li 0x80
+means Managed address configuration flag bit,
+and Bit 6
+.Pq Li 0x40
+means Other stateful configuration flag bit.
+Bit 4
+.Pq Li 0x10
+and Bit 3
+.Pq Li 0x08
+are used to encode router preference.
+0x01 means high, 0x00 means medium, and 0x11 means low.
+The default value is 0.
+.It Cm \&rltime
+(num) Router lifetime field
+(unit: seconds).
+Its value must be no greater than 3600000.
+When
+.Nm rtadvd
+runs on a host, this value must explicitly set 0 on all the
+advertising interfaces as described in
+.Xr rtadvd 8 .
+The default value is 1800.
+.It Cm \&rtime
+(num) Reachable time field
+(unit: milliseconds).
+The default value is 0, which means unspecified by this router.
+.It Cm \&retrans
+(num) Retrans Timer field
+(unit: milliseconds).
+The default value is 0, which means unspecified by this router.
+.El
+.Pp
+The following items are for ICMPv6 prefix information option,
+which will be attached to router advertisement header.
+These items can be omitted, then
+.Nm rtadvd
+will automatically get appropriate prefixes from the kernel's routing table,
+and advertise the prefixes with the default parameters.
+.Bl -tag -width indent
+.It Cm \&clockskew
+(num) Time skew to adjust link propagation delays and clock skews
+betwen routers on the link
+(unit: seconds).
+This value is used in consistency check for locally-configured and
+advertised prefix lifetimes, and has its meaning when the local router
+configures a prefix on the link with a lifetime that decrements in
+real time.
+If the value is 0, it means the consistency check will be skipped
+for such prefixes.
+The default value is 0.
+.It Cm \&addrs
+(num) Number of prefixes.
+Its default is 0, so it must explicitly be set to positve values
+if you want to specify any prefix information option.
+If its value is 0,
+.Xr rtadvd 8
+looks up the system routing table and
+advertise the prefixes corresponding to interface routes
+on the interface.
+If its value is more than 1, you must specify the index of the prefix
+for each item below.
+Indices vary from 0 to N-1, where N is the
+value of
+.Cm addrs .
+Each index shall follow the name of each item, e.g.,
+.Dq prefixlen2 .
+.It Cm \&prefixlen
+(num) Prefix length field.
+The default value is 64.
+.It Cm \&pinfoflags
+(num) Flags field in prefix information option.
+Bit 7
+.Pq Li 0x80
+means On-link flag bit,
+and Bit 6
+.Pq Li 0x40
+means Autonomous address-configuration flag bit.
+The default value is 0xc0, i.e., both bits are set.
+.It Cm \&addr
+(str) The address filled into Prefix field.
+Since
+.Dq \&:
+is used for
+.Xr termcap 5
+file format as well as IPv6 numeric address, the field MUST be quoted by
+doublequote character.
+This field cannot be
+omitted if the value of
+.Cm addrs
+is more than 0.
+.It Cm \&vltime
+(num) Valid lifetime field
+(unit: seconds).
+The default value is 2592000 (30 days).
+.It Cm \&vltimedecr
+(bool) This item means the advertised valid lifetime will decrements
+in real time, which is disabled by default.
+.It Cm \&pltime
+(num) Preferred lifetime field
+(unit: seconds).
+The default value is 604800 (7 days).
+.It Cm \&pltimedecr
+(bool) This item means the advertised preferred lifetime will decrements
+in real time, which is disabled by default.
+.El
+.Pp
+The following item is for ICMPv6 MTU option,
+which will be attached to router advertisement header.
+This item can be omitted, then
+.Nm rtadvd
+will use the default value.
+.Bl -tag -width indent
+.It Cm \&mtu
+(num or str) MTU (maximum transmission unit) field.
+If 0 is specified, it means that the option will not be included.
+The default value is 0.
+If the special string
+.Dq auto
+is specified for this item, MTU option will be included and its value
+will be set to the interface MTU automatically.
+.El
+.Pp
+The following item controls ICMPv6 source link-layer address option,
+which will be attached to router advertisement header.
+As noted above, you can just omit the item, then
+.Nm rtadvd
+will use the default value.
+.Bl -tag -width indent
+.It Cm \&nolladdr
+(bool) By default
+(if
+.Cm \&nolladdr
+is not specified),
+.Xr rtadvd 8
+will try to get link-layer address for the interface from the kernel,
+and attach that in source link-layer address option.
+If this capability exists,
+.Xr rtadvd 8
+will not attach source link-layer address option to
+router advertisement packets.
+.El
+.Pp
+The following item controls ICMPV6 home agent information option,
+which was defined with mobile IPv6 support.
+It will be attached to router advertisement header just like other options do.
+.Bl -tag -width indent
+.It Cm \&hapref
+(num) Specifies home agent preference.
+If set to non-zero,
+.Cm \&hatime
+must be present as well.
+.It Cm \&hatime
+(num) Specifies home agent lifetime.
+.El
+.Pp
+When mobile IPv6 support is turned on for
+.Xr rtadvd 8 ,
+advertisement interval option will be attached to router advertisement
+packet, by configuring
+.Cm \&maxinterval
+explicitly.
+.Pp
+The following items are for ICMPv6 route information option,
+which will be attached to router advertisement header.
+These items are optional.
+.Bl -tag -width indent
+.It Cm \&routes
+(num) Number of routes.
+Its default is 0, so it must explicitly be set to positve values
+if you want to specify any route information option.
+If its value is 0, no route information is sent.
+If its value is more than 1, you must specify the index of the routes
+for each item below.
+Indices vary from 0 to N-1, where N is the
+value of
+.Cm routes.
+Each index shall follow the name of each item, e.g.,
+.Dq rtrplen2 .
+.It Cm \&rtrplen
+(num) Prefix length field in route information option.
+The default value is 64.
+.It Cm \&rtrflags
+(num) Flags field in route information option.
+Bit 4
+.Pq Li 0x10
+and
+and Bit 3
+.Pq Li 0x08
+are used to encode router preference for the route.
+The default value is 0x00, i.e. medium router preference.
+.It Cm \&rtrprefix
+(str) The prefix filled into the Prefix field of route information option.
+Since
+.Dq \&:
+is used for
+.Xr termcap 5
+file format as well as IPv6 numeric address, the field MUST be quoted by
+doublequote character.
+This field cannot be
+omitted if the value of
+.Cm addrs
+is more than 0.
+.It Cm \&rtrltime
+(num) route lifetime field in route information option.
+(unit: seconds).
+The default value is 2592000 (30 days). (not specified in draft-draves-router-selection-01.txt now)
+.El
+You can also refer one line from another by using
+.Cm tc
+capability.
+See
+.Xr termcap 5
+for details on the capability.
+.Sh EXAMPLES
+As presented above, all of the advertised parameters have default values
+defined in specifications, and hence you usually do not have to set them
+by hand, unless you need special non-default values.
+It can cause interoperability problem if you use an ill-configured
+parameter.
+.Pp
+To override a configuration parameter, you can specify the parameter alone.
+With the following configuration,
+.Xr rtadvd 8
+overrides the router lifetime parameter for the
+.Li ne0
+interface.
+.Bd -literal -offset
+ne0:\\
+	:rltime#0:
+.Ed
+.Pp
+The following example manually configures prefixes advertised from the
+.Li ef0
+interface.
+The configuration must be used with the
+.Fl s
+option to
+.Xr rtadvd 8 .
+.Bd -literal -offset
+ef0:\\
+	:addrs#1:addr="3ffe:501:ffff:1000::":prefixlen#64:
+.Ed
+.Pp
+The following example presents the default values in an explicit manner.
+The configuration is provided just for reference purposes;
+YOU DO NOT NEED TO HAVE IT AT ALL.
+.Bd -literal -offset
+default:\\
+	:chlim#64:raflags#0:rltime#1800:rtime#0:retrans#0:\\

+.Sh NAME
+.Nm rtprio ,
+.Nm idprio
+.Nd execute, examine or modify a utility's or process's realtime
+or idletime scheduling priority
+.Sh SYNOPSIS
+.Nm [id|rt]prio
+.Nm [id|rt]prio
+.Oo Fl Oc Ns Ar pid
+.Nm [id|rt]prio
+.Ar priority
+.Ar command
+.Op args
+.Nm [id|rt]prio
+.Ar priority
+.Fl Ar pid
+.Nm [id|rt]prio
+.Fl t
+.Ar command
+.Op args
+.Nm [id|rt]prio
+.Fl t
+.Fl Ar pid
+.Sh DESCRIPTION
+The
+.Nm
+utility is used for controlling realtime process scheduling.
+.Pp
+The
+.Nm idprio
+utility is used for controlling idletime process scheduling, and can be called
+with the same options as
+.Nm .
+.Pp
+A process with a realtime priority is not subject to priority
+degradation, and will only be preempted by another process of equal or
+higher realtime priority.
+.Pp
+A process with an idle priority will run only when no other
+process is runnable and then only if its idle priority is equal or
+greater than all other runnable idle priority processes.
+.Pp
+Both
+.Nm
+or
+.Nm idprio
+when called without arguments will return the realtime priority
+of the current process.
+.Pp
+If
+.Nm
+is called with 1 argument, it will return the realtime priority
+of the process with the specified
+.Ar pid .
+.Pp
+If
+.Ar priority
+is specified, the process or program is run at that realtime priority.
+If
+.Fl t
+is specified, the process or program is run as a normal (non-realtime)
+process.
+.Pp
+If
+.Ar -pid
+is specified, the process with the process identifier
+.Ar pid
+will be modified, else if
+.Ar command
+is specified, that program is run with its arguments.
+.Pp
+.Ar Priority
+is an integer between 0 and RTP_PRIO_MAX (usually 31). 0 is the
+highest priority
+.Pp
+.Ar Pid
+of 0 means "the current process".
+.Pp
+Only root is allowed to set realtime or idle priority for a process.
+.Sh DIAGNOSTICS
+If
+.Nm
+execute a command, the exit value is that of the command executed.
+In all other cases,
+.Nm
+exits 0 on success, and 1 for all other errors.
+.Sh EXAMPLES
+To see which realtime priority the current process is at:
+.Bd -literal -offset indent -compact
+.Sy "rtprio"
+.Ed
+.Pp
+To see which realtime priority of process
+.Em 1423 :
+.Bd -literal -offset indent -compact
+.Sy "rtprio 1423"
+.Ed
+.Pp
+To run
+.Xr cron 8
+at the lowest realtime priority:
+.Bd -literal -offset indent -compact
+.Sy "rtprio 31 cron"
+.Ed
+.Pp
+To change the realtime priority of process
+.Em 1423
+to
+.Em 16 :
+.Bd -literal -offset indent -compact
+.Sy "rtprio 16 -1423"
+.Ed
+.Pp
+To run
+.Xr tcpdump 1
+without realtime priority:
+.Bd -literal -offset indent -compact
+.Sy "rtprio -t tcpdump"
+.Ed
+.Pp
+To change the realtime priority of process
+.Em 1423
+to
+.Dv RTP_PRIO_NORMAL
+(non-realtime/normal priority):
+.Bd -literal -offset indent -compact
+.Sy "rtprio -t -1423"
+.Ed
+.Pp
+To make depend while not disturbing other machine usage:
+.Bd -literal -offset indent -compact
+.Sy "idprio 31 make depend"
+.Ed
+.Sh SEE ALSO

+.Xr ps 1 ,
+.Xr rtprio 2 ,
+.Xr setpriority 2 ,
+.Xr nice 3 ,
+.Xr renice 8
+.Sh HISTORY
+The
+.Nm
+utility appeared in
+.Fx 2.0 ,
+but is similar to the HP-UX version.
+.Sh CAVEATS
+You can lock yourself out of the system by placing a cpu-heavy
+process in a realtime priority.
+.Sh BUGS
+There is no way to set/view the realtime priority of process 0
+(swapper) (see
+.Xr ps 1 ) .
+.Pp
+There is in
+.Fx
+no way to ensure that a process page is present in memory therefore
+the process may be stopped for pagein (see
+.Xr mprotect 2 ,
+.Xr madvise 2 ) .
+.Pp
+Under
+.Fx
+system calls are currently never preempted, therefore non-realtime
+processes can starve realtime processes, or idletime processes can
+starve normal priority processes.
+.Sh AUTHORS
+.An -nosplit
+.An Henrik Vestergaard Draboel Aq hvd@terry.ping.dk
+is the original author.
+This
+implementation in
+.Fx
+was substantially rewritten by
+.An David Greenman .

+.\"
+.Sh DESCRIPTION
+.Nm
+is the daemon program to send ICMPv6 Router Solicitation messages
+on the specified interfaces.
+If a node (re)attaches to a link,
+.Nm
+sends some Router Solicitations on the link destined to the link-local scope
+all-routers multicast address to discover new routers
+and to get non link-local addresses.
+.Pp
+.Nm
+should be used on IPv6 hosts
+(non-router nodes)
+only.
+.Pp
+If you invoke the program as
+.Nm rtsol ,
+it will transmit probes from the specified
+.Ar interface ,
+without becoming a daemon.
+In other words,
+.Nm rtsol
+behaves as
+.Do
+.Nm
+.Fl f1
+.Ar interfaces
+.Dc .
+.Pp
+Specifically,
+.Nm
+sends at most 3 Router Solicitations on an interface
+after one of the following events:
+.Pp
+.Bl -bullet -compact
+.It
+Just after invocation of
+.Nm
+daemon.
+.It
+The interface is up after a temporary interface failure.
+.Nm
+detects such failures by periodically probing to see if the status
+of the interface is active or not.
+Note that some network cards and drivers do not allow the extraction
+of link state.
+In such cases,
+.Nm
+cannot detect the change of the interface status.
+.It
+Every 60 seconds if the
+.Fl m
+option is specified and the
+.Nm
+daemon cannot get the interface status.
+This feature does not conform to the IPv6 neighbor discovery
+specification, but is provided for mobile stations.
+The default interval for router advertisements, which is on the order of 10
+minutes, is slightly long for mobile stations.
+This feature is provided
+for such stations so that they can find new routers as soon as possible
+when they attach to another link.
+.El
+.Lp
+Once
+.Nm
+has sent a Router Solicitation, and has received a valid Router Advertisement,
+it refrains from sending additional solicitations on that interface, until
+the next time one of the above events occurs.
+.Lp
+When sending a Router Solicitation on an interface,
+.Nm
+includes a Source Link-layer address option if the interface
+has a link-layer address.
+.Pp
+Upon receipt of signal
+.Dv SIGUSR1 ,
+.Nm
+will dump the current internal state into
+.Pa /var/run/rtsold.dump .
+.\"
+.Sh OPTIONS
+.Bl -tag -width indent
+.It Fl a
+Autoprobe outgoing interface.
+.Nm
+will try to find a non-loopback, non-point-to-point, IPv6-capable interface.
+If
+.Nm
+finds multiple interfaces,
+.Nm
+will exit with error.
+.\"
+.It Fl d

+.It Fl D
+Enable more debugging including the printing of internal timer information.
+.It Fl f
+.Fl f
+prevents
+.Nm
+from becoming a daemon (foreground mode).
+Warning messages are generated to standard error
+instead of
+.Xr syslog 3 .
+.It Fl m
+Enable mobility support.
+If this option is specified,
+.Nm
+sends probing packets to default routers that have advertised Router
+Advertisements
+when the node (re)attaches to an interface.
+Moreover, if the option is specified,
+.Nm
+periodically sends Router Solicitation on an interface that does not support

+.Sh SEE ALSO
+.Xr rtadvd 8 ,

+.\"
+.Sh HISTORY
+The
+.Nm
+command is based on the
+.Nm rtsol
+command, which first appeared in WIDE/KAME IPv6 protocol stack kit.
+.Nm rtsol
+is now integrated into
+.Xr rtsold 8 .
+.\"
+.Sh BUGS
+In some operating systems, when a PCMCIA network card is removed
+and reinserted, the corresponding interface index is changed.
+However,
+.Nm
+assumes such changes will not occur, and always uses the index that
+it got at invocation. As a result,
+.Nm
+may not work if you reinsert a network card.
+In such a case,
+.Nm
+should be killed and restarted.
+.Pp
+The IPv6 autoconfiguration specification assumes a single-interface host.
+You may see kernel error messages if you try to autoconfigure a host with
+multiple interfaces.
+Also, it seems contradictory for
+.Nm
+to accept multiple
+.Ar interface
+arguments.

+.Sh NAME
+.Nm rwhod
+.Nd system status server
+.Sh SYNOPSIS
+.Nm
+.Op Fl i
+.Op Fl p
+.Op Fl l
+.Op Fl m Op Ar ttl
+.Sh DESCRIPTION
+.Nm Rwhod
+is the server which maintains the database used by the
+.Xr rwho 1
+and
+.Xr ruptime 1
+programs.  Its operation is predicated on the ability to
+.Em broadcast
+or
+.Em multicast
+messages on a network.
+.Pp
+.Nm Rwhod
+operates as both a producer and consumer of status information,
+unless the
+.Fl l
+(listen mode) option is specified, in which case
+it acts as a consumer only.
+As a producer of information it periodically
+queries the state of the system and constructs
+status messages which are broadcasted or multicasted on a network.
+As a consumer of information, it listens for other
+.Nm
+servers' status messages, validating them, then recording
+them in a collection of files located in the directory
+.Pa /var/rwho .
+.Pp
+The
+.Fl i
+option enables insecure mode, which causes
+.Nm
+to ignore the source port on incoming packets.
+.Pp
+The
+.Fl p
+option tells
+.Nm
+to ignore all
+.Dv POINTOPOINT
+interfaces.  This is useful if you do not wish to keep dial on demand
+interfaces permanently active.
+.Pp
+The
+.Fl l
+option enables listen mode, which causes
+.Nm
+to not broadcast any information.
+This allows you to monitor other machines'
+.Nm
+information, without broadcasting your own.
+.Pp
+The
+.Fl m
+option causes
+.Nm
+to use IP multicast (instead of
+broadcast) on all interfaces that have
+the IFF_MULTICAST flag set in their "ifnet" structs
+(excluding the loopback interface).  The multicast
+reports are sent with a time-to-live of 1, to prevent
+forwarding beyond the directly-connected subnet(s).
+.Pp
+If the optional
+.Ar ttl
+argument is supplied with the
+.Fl m
+flag,
+.Nm
+will send IP multicast datagrams with a
+time-to-live of
+.Ar ttl ,
+via a SINGLE interface rather
+than all interfaces.
+.Ar ttl
+must be between 0 and
+32 (or MAX_MULTICAST_SCOPE).  Note that
+.Fl m Ar 1
+is different from
+.Fl m ,
+in that
+.Fl m Ar 1
+specifies transmission on one interface only.
+.Pp
+When
+.Fl m
+is used without a
+.Ar ttl
+argument, the program accepts multicast
+.Nm
+reports from all multicast-capable interfaces.  If a
+.Ar ttl
+argument is given, it accepts multicast reports from only one interface, the
+one on which reports are sent (which may be controlled via the host's routing
+table).  Regardless of the
+.Fl m
+option, the program accepts broadcast or
+unicast reports from all interfaces.  Thus, this program will hear the
+reports of old, non-multicasting
+.Nm Ns s ,
+but, if multicasting is used,
+those old
+.Nm Ns s
+won't hear the reports generated by this program.
+.Pp
+The server transmits and receives messages at the port indicated
+in the ``who'' service specification; see
+.Xr services 5 .
+The messages sent and received, are of the form:
+.Bd -literal -offset indent
+struct	outmp {
+	char	out_line[8];		/* tty name */
+	char	out_name[8];		/* user id */
+	long	out_time;		/* time on */
+};
+
+struct	whod {
+	char	wd_vers;
+	char	wd_type;
+	char	wd_fill[2];
+	int	wd_sendtime;
+	int	wd_recvtime;
+	char	wd_hostname[32];
+	int	wd_loadav[3];
+	int	wd_boottime;
+	struct	whoent {
+		struct	outmp we_utmp;
+		int	we_idle;
+	} wd_we[1024 / sizeof (struct whoent)];
+};
+.Ed
+.Pp
+All fields are converted to network byte order prior to
+transmission.  The load averages are as calculated by the
+.Xr w 1
+program, and represent load averages over the 5, 10, and 15 minute
+intervals prior to a server's transmission; they are multiplied by 100
+for representation in an integer.  The host name
+included is that returned by the
+.Xr gethostname 3
+system call, with any trailing domain name omitted.
+The array at the end of the message contains information about
+the users logged in to the sending machine.  This information
+includes the contents of the
+.Xr utmp 5
+entry for each non-idle terminal line and a value indicating the
+time in seconds since a character was last received on the terminal line.
+.Pp
+Messages received by the
+.Nm rwho
+server are discarded unless they originated at an
+.Nm rwho
+server's port or the
+.Fl i
+option was specified.  In addition, if the host's name, as specified
+in the message, contains any unprintable
+.Tn ASCII
+characters, the
+message is discarded.  Valid messages received by
+.Nm
+are placed in files named
+.Pa whod.hostname
+in the directory
+.Pa /var/rwho .
+These files contain only the most recent message, in the
+format described above.
+.Pp
+Status messages are generated approximately once every
+3 minutes.
+.Nm Rwhod
+performs an
+.Xr nlist 3
+on
+.Pa /boot/kernel/kernel
+every 30 minutes to guard against
+the possibility that this file is not the system
+image currently operating.
+.Sh SEE ALSO
+.Xr ruptime 1 ,
+.Xr rwho 1
+.Sh BUGS
+Status information should be sent only upon request rather than continuously.
+People often interpret the server dying
+or network communication failures
+as a machine going down.
+.Sh HISTORY
+The
+.Nm
+command appeared in
+.Bx 4.2 .

+.Sh NAME
+.Nm sa
+.Nd print system accounting statistics
+.Sh SYNOPSIS
+.Nm
+.Op Fl abcdDfijkKlmnqrstu
+.Op Fl v Ar cutoff
+.Op Ar
+.Sh DESCRIPTION
+The
+.Nm
+utility reports on, cleans up,
+and generally maintains system
+accounting files.
+.Pp
+.Nm Sa
+is able to condense the information in
+.Pa /var/account/acct
+into the summary files
+.Pa /var/account/savacct
+and
+.Pa /var/account/usracct ,
+which contain system statistics according
+to command name and login id, respectively.
+This condensation is desirable because on a
+large system,
+.Pa /var/account/acct
+can grow by hundreds of blocks per day.
+The summary files are normally read before
+the accounting file, so that reports include
+all available information.
+.Pp
+If file names are supplied, they are read instead of
+.Pa /var/account/acct .
+After each file is read, if the summary
+files are being updated, an updated summary will
+be saved to disk.  Only one report is printed,
+after the last file is processed.
+.Pp
+The labels used in the output indicate the following, except
+where otherwise specified by individual options:
+.Bl -tag -width k*sec
+.It Dv avio
+Average number of I/O operations per execution
+.It Dv cp
+Sum of user and system time, in minutes
+.It Dv cpu
+Same as
+.Dv cp
+.It Dv k
+CPU-time averaged core usage, in 1k units
+.It Dv k*sec
+CPU storage integral, in 1k-core seconds
+.It Dv re
+Real time, in minutes
+.It Dv s
+System time, in minutes
+.It Dv tio
+Total number of I/O operations
+.It Dv u
+User time, in minutes
+.El
+.Pp
+The options to
+.Nm
+are:
+.Bl -tag -width Ds
+.It Fl a
+List all command names, including those containing unprintable
+characters and those used only once.  By default,
+.Nm
+places all names containing unprintable characters and
+those used only once under the name ``***other''.
+.It Fl b
+If printing command statistics, sort output by the sum of user and system
+time divided by number of calls.
+.It Fl c
+In addition to the number of calls and the user, system and real times
+for each command, print their percentage of the total over all commands.
+.It Fl d
+If printing command statistics, sort by the average number of disk
+I/O operations.  If printing user statistics, print the average number of
+disk I/O operations per user.
+.It Fl D
+If printing command statistics, sort and print by the total number
+of disk I/O operations.
+.It Fl f
+Force no interactive threshold comparison with the
+.Fl v
+option.
+.It Fl i
+Do not read in the summary files.
+.It Fl j
+Instead of the total minutes per category, give seconds per call.
+.It Fl k
+If printing command statistics, sort by the cpu-time average memory
+usage.  If printing user statistics, print the cpu-time average
+memory usage.
+.It Fl K
+If printing command statistics, print and sort by the cpu-storage integral.
+.It Fl l
+Separate system and user time; normally they are combined.
+.It Fl m
+Print per-user statistics rather than per-command statistics.
+.It Fl n
+Sort by number of calls.
+.It Fl q
+Create no output other than error messages.
+.It Fl r
+Reverse order of sort.
+.It Fl s
+Truncate the accounting files when done and merge their data
+into the summary files.
+.It Fl t
+For each command, report the ratio of real time to the sum
+of user and system cpu times.
+If the cpu time is too small to report, ``*ignore*'' appears in
+this field.
+.It Fl u
+Superseding all other flags, for each entry
+in the accounting file, print the user ID, total seconds of cpu usage,
+total memory usage, number of I/O operations performed, and
+command name.
+.It Fl v Ar cutoff
+For each command used
+.Ar cutoff
+times or fewer, print the command name and await a reply
+from the terminal.  If the reply begins with ``y'', add
+the command to the category ``**junk**''.  This flag is
+used to strip garbage from the report.
+.El
+.Pp
+By default, per-command statistics will be printed.  The number of
+calls, the total elapsed time in minutes, total cpu and user time
+in minutes, average number of I/O operations, and CPU-time
+averaged core usage will be printed.  If the
+.Fl m
+option is specified, per-user statistics will be printed, including
+the user name, the number of commands invoked, total cpu time used
+(in minutes), total number of I/O operations, and CPU storage integral
+for each user.  If the
+.Fl u
+option is specified, the uid, user and system time (in seconds),
+CPU storage integral, I/O usage, and command name will be printed
+for each entry in the accounting data file.
+.Pp
+If the
+.Fl u
+flag is specified, all flags other than
+.Fl q
+are ignored.  If the
+.Fl m
+flag is specified, only the
+.Fl b ,
+.Fl d ,
+.Fl i ,
+.Fl k ,
+.Fl q ,
+and
+.Fl s
+flags are honored.

+.Sh BUGS
+The number of options to this program is absurd, especially considering
+that there's not much logic behind their lettering.
+.Pp
+The field labels should be more consistent.
+.Pp
+The VM system does not record the CPU storage integral.
+.Sh CAVEATS
+While the behavior of the options in this version of
+.Nm
+was modeled after the original version, there are some intentional
+differences and undoubtedly some unintentional ones as well.  In
+particular, the
+.Fl q
+option has been added, and the
+.Fl m
+option now understands more options than it used to.
+.Pp
+The formats of the summary files created by this version of
+.Nm
+are very different from the those used by the original version.
+This is not considered a problem, however, because the accounting record
+format has changed as well (since user ids are now 32 bits).

+This is the FreeBSD DiskLabel Editor.
+
+NOTE: If you're entering this editor from the update procedure then
+you probably shouldn't (C)reate anything at all but rather use only
+the (M)ount command to check and mount existing partitions for
+upgrading.
+
+If you would like the label editor to do most of the following for
+you, simply type `A' for automatic partitioning of the disk.
+
+If you wish to create partitions manually you may do so by moving the
+highlighted selection bar with the arrow keys over the FreeBSD
+partition(s) displayed at the top of the screen.  Typing (C)reate
+while a partition with available free space is selected will allow you
+to create a BSD partition inside of it using some or all of its
+available space.
+
+Typing (M)ount over an existing partition entry (displayed in the
+middle of the screen) will allow you to set a mount point for it
+without initializing it.  If you want it initialized, use the (T)oggle
+command to flip the Newfs flag.  When Newfs is set to "Y", the
+filesystem in question will be ERASED and rebuilt from scratch!
+
+
+You should use this editor to create at least the following
+filesystems:
+
+        Name    Purpose                 Min Size?       Optional?
+        ----    -------                 ---------       ---------
+        /       Root filesystem         20MB            No
+        swap    Swap space              2 * MEM         No
+        /usr    System & user files     80MB or more    Yes
+
+Note: If you do not create a /usr filesystem then your / filesystem
+will need to be bigger - at least 100MB.  This is not recommended as
+any media errors that may occur during disk I/O to user files will
+corrupt the filesystem containing vital system files as well.  It is
+for this reason that / is generally kept on its own filesystem, where
+it should be considered essentially "read only" in your administration
+of it.
+
+Swap space is a little tricker, and the rule of "2 * MEM" is simply a
+best-guess approximation and not necessarily accurate for your
+intended usage of the system.  If you intend to use the system heavily
+in a server or multi-user application, you may be well advised to
+increase this size.  You may also create swap space on multiple drives
+for a larger "total" swap and this is, in fact, recommended if you
+have multiple, fast drives for which such load-balancing can only help
+overall I/O performance.
+
+The /usr filesystem should be sized according to what kind of
+distributions you're trying to load and how many packages you intend
+to install in locations like /usr/local.  You can also make /usr/local
+a separate filesystem if you don't want to risk filling up your /usr
+by mistake.
+
+Another useful filesystem to create is /var, which contains mail, news
+printer spool files and other temporary items.  It is a popular
+candidate for a separate partition and should be sized according to
+your estimates of the amount of mail, news or spooled print jobs that
+may be stored there.
+
+WARNING: If you do not create a separate filesystem for /var, space
+for such files will be allocated out of the root (/) filesystem
+instead.  You may therefore wish to make the / partition bigger if you
+expect a lot of mail or news and do not want to make /var its own
+partition.
+
+If you're new to this installation, you might also want to read the
+following explanation of how FreeBSD's new "slice" paradigm for
+looking at disk storage works:
+
+
+In FreeBSD's new system, a device name can be broken up into up to 3
+parts.  Take a typical name like ``/dev/da0s1a'':
+
+      The first three characters represent the drive name.  If we had
+      a system with two SCSI drives on it then we'd see /dev/da0 and
+      /dev/da1 as the device entries representing the entire drives.
+
+      Next you have the "slice" (or "FDISK Partition") number,
+      as seen in the Partition Editor.  Assuming that our da0
+      contained two slices, a FreeBSD slice and a DOS slice, that
+      would give us /dev/da0s1 and /dev/da0s2 as device entries pointing
+      to the entire slices.
+
+      Next, if a slice is a FreeBSD slice, you can have a number of
+      (confusingly named) "partitions" inside of it.
+
+      These partitions are where various filesystems or swap areas live,
+      and using our hypothetical two-SCSI-disk machine again, we might
+      have something like the following layout on da0:
+
+              Name            Mountpoint
+              ----            ----------
+              da0s1a          /
+              da0s1b          <swap space>
+              da0s1e          /usr
+
+Once you understand all this, then the purpose of the label editor
+becomes fairly clear:  You're carving up the FreeBSD slices displayed
+at the top of the screen into smaller pieces, which are displayed in
+the middle of the screen, and then assigning FreeBSD file system names
+(mount points) to them.
+
+You can also use the label editor to mount existing partitions/slices
+into your filesystem hierarchy, as is frequently done for DOS FAT
+slices.  For FreeBSD partitions, you can also toggle the "newfs" state
+so that the partitions are either (re)created from scratch or simply
+checked and mounted (the contents are preserved).
+
+If you set (S)oftUpdates on a filesystem, it will cause the
+"Soft Updates" policy to be in effect for it.  This basically causes
+both metadata and data blocks to be written asynchronously to disk,
+but with extra state information which causes the metadata and any
+related data blocks to be committed in a single transaction.  This
+results in async metadata update speeds (which are considerably
+faster than the default sync) without the potential for data loss
+which could occur if you simply mounted the filesystem with purely
+"async" update policy and then had a power failure.  If you wish
+to later turn the softupdates policy back off, use the command
+"tunefs -n disable devicename".  NOTE:  It is probably not wise
+to use this on your root filesystem unless you have a large
+(e.g. non-standard size) root.  The reason is that smaller filesystems
+with significant activity can temporarily overflow if the soft updates
+policy results in free'd blocks not being "garbage collected" as fast
+as they're being requested.
+
+When you're done, type `Q' to exit.
+
+No actual changes will be made to the disk until you (C)ommit from the
+Install menu or (W)rite directly from this one.  You're working with
+what is essentially a copy of the disk label(s), both here and in the
+FDISK Partition Editor, and the actual on-disk labels won't be
+affected by any changes you make until you explicitly say so.

+This is the Main Slice (``FDISK'' or PC-style Partition) Editor.
+
+Possible commands are printed at the bottom and the Master Boot Record
+contents are shown at the top.  You can move up and down with the
+arrow keys and (C)reate a new slice whenever the highlighted
+selection bar is over a slice whose type is marked as "unused."
+
+You are expected to leave this screen with at least one slice
+marked "FreeBSD."  Note that unlike Linux, you don't need to create
+multiple FreeBSD FDISK partition entries for different things like
+swap, file systems, etc.  The usual convention is to create ONE
+FreeBSD slice (FDISK partition) per drive and then subsection this slice
+into swap and file systems with the Label editor.
+
+No actual changes will be made to the disk until you (C)ommit from the
+Install menu or use the (W)rite option here!  You're working with what
+is essentially a copy of the disk label(s), both here and in the Label
+Editor.
+
+If you want to use the entire disk for FreeBSD, type `A'.  You'll be
+asked whether or not you wish to keep the disk (potentially) compatible
+with other operating systems, i.e. the information in the FDISK table
+should be kept valid.  If you select the default of `Yes', slices will be
+aligned to fictitious cylinder boundaries and space will be reserved
+in front of the FreeBSD slice for a [future] possible boot manager.
+
+For the truly dedicated disk case, you can select `No' at the
+compatibility prompt.  In that case, all BIOS geometry considerations
+will no longer be in effect and you can safely ignore any
+``The detected geometry is invalid'' warning messages you may later
+see.  It is also not necessary in this case to set a slice bootable
+or install an MBR boot manager as both things are then irrelevant.
+
+The FreeBSD slice will start at absolute sector 0 of the disk (so that
+FreeBSD's disk label is identical to the Master Boot Record) and
+extend to the very last sector of the disk medium.  Needless to say,
+such a disk cannot have any sort of a boot manager, `disk manager',
+or anything else that has to interact with the BIOS.  This option is
+therefore only considered safe for SCSI disks and most IDE disks and
+is primarily intended for people who are going to set up a dedicated
+FreeBSD server or workstation, not a typical `home PC'.
+
+The flags field has the following legend:
+
+        '='  -- This slice is properly aligned.
+        '>'  -- This slice doesn't end before cylinder 1024
+        'R'  -- This slice contains the root (/) filesystem
+        'B'  -- Slice employs BAD144 bad-spot handling
+        'C'  -- This is the FreeBSD 2.0-compatibility slice (default)
+        'A'  -- This slice is marked active.
+
+If you select a slice for Bad144 handling, it will be scanned
+for bad blocks before any new filesystems are made on it.
+
+If no slice is marked Active, you will need to either install
+a Boot Manager (the option for which will be presented later in the
+installation) or set one Active before leaving this screen.
+
+To leave the slice editor, type `Q'.
+
+Final Note: If you're absolutely sure you know what you're doing
+      and you want to use the old "Dangerously Dedicated" mode
+      which is now deprecated by sysinstall, use the (purposely)
+      undocumented `F' key.

+.Os
+.Sh NAME
+.Nm sysinstall
+.Nd system installation and configuration tool
+.Sh SYNOPSIS
+.Nm
+.Op Ar var=value
+.Op Ar function
+.Op Ar ...
+.Sh DESCRIPTION
+.Nm
+is a utility for installing and configuring
+.Fx
+systems.
+It is the first utility invoked by the
+.Fx
+installation boot
+floppy and is also copied into
+.Pa /stand/sysinstall
+on newly installed
+.Fx
+systems for use in later configuring the system.
+.Pp
+The
+.Nm
+program is generally invoked without arguments for the default
+behavior, where the main installation/configuration menu is presented.
+.Pp
+On those occasions where it is deemed necessary to invoke a subsystem
+of sysinstall directly, however, it is also possible to do so by
+naming the appropriate function entry points on the command line.
+Since this action is essentially identical to running an installation
+script, each command-line argument corresponding to a line of script,
+the reader is encouraged to read the section on scripting for more
+information on this feature.
+.Sh NOTES
+.Nm
+is essentially nothing more than a monolithic C program with
+the ability to write MBRs and disk labels (through the services
+of the
+.Xr libdisk 3
+library) and install distributions or packages onto new and
+existing
+.Fx
+systems.  It also contains some extra intelligence
+for running as a replacement for
+.Xr init 8
+when it's invoked by the
+.Fx
+installation boot procedure.  It
+assumes very little in the way of additional utility support and
+performs most file system operations by calling the relevant syscalls
+(such as
+.Xr mount 2 )
+directly.
+.Pp
+.Nm
+currently uses the
+.Xr dialog 3
+library to do user interaction with simple ANSI line graphics, color
+support for which is enabled by either running on a syscons VTY or some
+other color-capable terminal emulator (newer versions of xterm will support
+color when using the
+.Dq xterm-color
+termcap entry).
+.Pp
+This product is currently at the end of its life cycle and will
+eventually be replaced.
+.Sh RUNNING SCRIPTS
+.Nm
+may be either driven interactively through its various internal menus
+or run in batch mode, driven by an external script.  Such a script may
+be loaded and executed in one of 3 ways:
+.Bl -tag -width Ds
+.It Sy "LOAD_CONFIG_FILE"
+If
+.Nm
+is compiled with LOAD_CONFIG_FILE set in the environment
+(or in the Makefile) to some value, then that value will
+be used as the filename to automatically look for and load
+when
+.Nm
+starts up and with no user interaction required.
+This option is aimed primarily at large sites who wish to create a
+single prototype install for multiple machines with largely identical
+configurations and/or installation options.
+.It Sy "MAIN MENU"
+If
+.Nm
+is run interactively, that is to say in the default manner, it will
+bring up a main menu which contains a "load config file" option.
+Selecting this option will prompt for the name of a script file which
+it then will attempt to load from a DOS or UFS formatted floppy.
+.It Sy "COMMAND LINE"
+Each command line argument is treated as a script directive
+when
+.Nm
+is run in multi-user mode.  Execution ends either by explicit request
+(e.g. calling the
+.Ar shutdown
+directive), upon reaching the end of the argument list or on error.
+.Pp
+For example:
+.Bd -literal
+/stand/sysinstall _ftpPath=ftp://ziggy/pub/ mediaSetFTP configPackages
+.Ed
+.Pp
+Would initialize
+.Nm
+for FTP installation media (using the server `ziggy') and then
+bring up the package installation editor, exiting when finished.
+.El
+.Sh SCRIPT SYNTAX
+A script is a list of one or more directives, each directive taking
+the form of:
+.Pp
+.Ar var=value
+.Pp
+.Ar function
+.Pp
+or
+.Ar #somecomment
+.Pp
+Where
+.Ar var=value
+is the assignment of some internal
+.Nm
+variable, e.g. "ftpPass=FuNkYChiKn", and
+.Ar function
+is the name of an internal
+.Nm
+function, e.g. "mediaSetFTP", and
+.Ar #comment
+is a single-line comment for documentation purposes (ignored by
+sysinstall).  Each directive must be by itself on a single line,
+functions taking their arguments by examining known variable names.
+This requires that you be sure to assign the relevant variables before
+calling a function which requires them.
+.Pp
+The
+.Ar noError
+variable can be assigned before each directive: this will cause any error
+detected while processing the directive itself to be ignored.
+The value of
+.Ar noError
+will automatically reset to the default "unassigned" every time a directive is
+processed.
+.Pp
+When and where a function depends on the settings of one or more variables
+will be noted in the following table:
+.Pp
+.Sy "Function Glossary" :
+.Pp
+.Bl -tag -width indent
+.It configAnonFTP
+Invoke the Anonymous FTP configuration menu.
+.Pp
+.Sy Variables :
+None
+.It configRouter
+Select which routing daemon you wish to use, potentially
+loading any required 3rd-party routing daemons as necessary.
+.Pp
+.Sy Variables :
+.Bl -tag -width indent
+.It router
+can be set to the name of the desired routing daemon,
+e.g.\&
+.Dq routed
+or
+.Dq gated ,
+otherwise it is prompted for.
+.El
+.It configNFSServer
+Configure host as an NFS server.
+.Pp
+.Sy Variables :
+None
+.It configNTP
+Configure host as a user of the Network Time Protocol.
+.Pp
+.Sy Variables :
+.Bl -tag -width indent
+.It ntpdate_flags
+The flags to
+.Xr ntpdate 8 ,
+that is to say the name of the server to sync from.
+.El
+.It configPCNFSD
+Configure host to support PC NFS.
+.Pp
+.Sy Variables :
+.Bl -tag -width indent
+.It pcnfsd_pkg
+The name of the PCNFSD package to load if necessary (defaults to hard coded
+version).
+.El
+.It configPackages
+Bring up the interactive package management menu.
+.Pp
+.Sy Variables :
+None
+.It configUsers
+Add users and/or groups to the system.
+.Pp
+.Sy Variables :
+None
+.It configXEnvironment
+Configure the X display subsystem.
+.Pp
+.Sy Variables :
+None
+.It diskPartitionEditor
+Invokes the disk partition (MBR) editor.
+.Pp
+.Sy Variables :
+.Bl -tag -width findx
+.It geometry
+The disk geometry, as a cyls/heads/sectors formatted string.  Default: no
+change to geometry.
+.It partition
+Set to disk partitioning type or size, its value being
+.Ar free
+in order to use only remaining free space for
+.Fx ,
+.Ar all
+to use the entire disk for
+.Fx
+but maintain a proper partition
+table,
+.Ar existing
+to use an existing
+.Fx
+partition (first found),
+.Ar exclusive
+to use the disk in
+.Dq dangerously dedicated
+mode or, finally,
+.Ar somenumber
+to allocate
+.Ar somenumber
+blocks of available free space to a new
+.Fx
+partition.
+Default:  Interactive mode.
+.It bootManager
+is set to one of
+.Ar boot
+to signify the installation of a boot manager,
+.Ar standard
+to signify installation of a "standard" non-boot MGR DOS
+MBR or
+.Ar none
+to indicate that no change to the boot manager is desired.
+Default: none.
+.It diskInteractive
+If set, bring up the interactive disk partition editor.
+.El
+.Pp
+Note: Nothing is actually written to disk by this function, a explicit call to
+.Ar diskPartitionWrite
+being required for that to happen.
+.It diskPartitionWrite
+Causes any pending MBR changes (typically from the
+.Ar diskPartitionEditor
+function) to be written out.
+.Pp
+.Sy Variables :
+None
+.It diskLabelEditor
+Invokes the disk label editor.  This is a bit trickier from a script
+since you need to essentially label everything inside each
+.Fx
+(type 0xA5) partition created by the
+.Ar diskPartitionEditor
+function, and that requires knowing a few rules about how things are
+laid out.  When creating a script to automatically allocate disk space
+and partition it up, it is suggested that you first perform the
+installation interactively at least once and take careful notes as to
+what the slice names will be, then and only then hardwiring them into
+the script.
+.Pp
+For example, let's say you have a SCSI disk on which you've created a new
+.Fx
+partition in slice 2 (your DOS partition residing in slice 1).
+The slice name would be
+.Ar da0s2
+for the whole
+.Fx
+partition
+.Ar ( da0s1
+being your DOS primary
+partition).  Now let's further assume that you have 500MB in this
+partition and you want to sub-partition that space into root, swap,
+var and usr file systems for
+.Fx .
+Your invocation of the
+.Ar diskLabelEditor
+function might involve setting the following variables:
+.Bl -tag -width findx
+.It Li "da0s2-1=ufs 40960 /"
+A 20MB root file system (all sizes are in 512 byte blocks).
+.It Li "da0s2-2=swap 131072 /"
+A 64MB swap partition.
+.It Li "da0s2-3=ufs 204800 /var"
+A 100MB /var file system.
+.It Li "da0s2-4=ufs 0 /usr 1"
+With the balance of free space (around 316MB) going to the /usr
+file system and with soft-updates enabled (the argument following
+the mount point, if non-zero, means to set the soft updates flag).
+.El
+.Pp
+One can also use the
+.Ar diskLabelEditor
+for mounting or erasing existing partitions as well as creating new
+ones.  Using the previous example again, let's say that we also wanted
+to mount our DOS partition and make sure that an
+.Pa /etc/fstab
+entry is created for it in the new installation.  Before calling the
+.Ar diskLabelEditor
+function, we simply add an additional line:
+.Pp
+.Dl "da0s1=/dos_c N"
+.Pp
+before the call.  This tells the label editor that you want to mount
+the first slice on
+.Pa /dos_c
+and not to attempt to newfs it (not that
+.Nm
+would attempt this for a DOS partition in any case, but it could just
+as easily be an existing UFS partition being named here and the 2nd
+field is non-optional).
+.Pp
+You can also set the
+.Ar diskInteractive
+variable to request that the disk label editor use an interactive dialog
+to partition the disk instead of using variables to explicitly layout the
+disk as described above.
+.Pp
+Note:  No file system data is actually written to disk until an
+explicit call to
+.Ar diskLabelCommit
+is made.
+.It diskLabelCommit
+Writes out all pending disklabel information and creates and/or mounts any
+file systems which have requests pending from the
+.Ar diskLabelEditor
+function.
+.Pp
+.Sy Variables :
+None
+.It distReset
+Resets all selected distributions to the empty set (no distributions selected).
+.Pp
+.Sy Variables :
+None
+.It distSetCustom
+Allows the selection of a custom distribution set (e.g. not just on of the
+existing "canned" sets) with no user interaction.

+.Sh DISTRIBUTION MEDIA
+The following files can be used to affect the operation of
+.Nm
+when used during initial system installation.
+.Bl -tag -width ".Pa packages/INDEX"
+.It Pa cdrom.inf
+A text file of properties, listed one per line, that describe the
+contents of the media in use.
+The syntax for each line is simply
+.Dq Ar property No = Ar value .
+Currently, only the following properties are recognized.
+.Bl -tag -width ".Va CD_MACHINE_ARCH"
+.It Va CD_VERSION
+This property should be set to the
+.Fx
+version on the current
+media volume.
+For example,
+.Dq Li "CD_VERSION = 4.6" .
+.It Va CD_MACHINE_ARCH
+This property should be set to the architecture of the contents on
+this volume.
+This property is normally only used with
+.Fx
+products that contain
+CDs for different architectures, to provide better error messages if
+users try to install Alpha packages on an i386 machine.
+For example,
+.Dq Li "CD_MACHINE_ARCH = alpha" .
+.It Va VOLUME
+In a multi-volume collection (such as the
+.Fx
+4-CD set), the
+.Pa ports/INDEX
+file on each disc should contain the full package index for the set.
+The last field of the
+.Pa INDEX
+file denotes which volume the package
+appears on, and the
+.Va VOLUME
+property here defines the volume ID of the current disc.
+.El
+.It Pa packages/INDEX
+The package index file.
+Each package is listed on a separate line with additional meta-data
+such as the required dependencies.
+This index is generated by
+.Dq Li "make index"
+from the
+.Xr ports 7
+collection.
+When multi-volume support is enabled, an additional field should be
+added to each line indicating which media volume contains the given
+package.
+.El
+.Pp
+For information about building a full release of
+.Fx ,
+please see
+.Xr release 7 .
+.Sh FILES
+This utility may edit the contents of
+.Pa /etc/rc.conf ,
+.Pa /etc/hosts ,
+and
+.Pa /etc/resolv.conf
+as necessary to reflect changes in the network configuration.
+.Sh SEE ALSO
+If you have a reasonably complete source tree online, take
+a look at
+.Pa /usr/src/usr.sbin/sysinstall/install.cfg
+for a sample installation script.
+.Sh BUGS
+This utility is a prototype which lasted several years past
+its expiration date and is greatly in need of death.

+.Sh NAME
+.Nm setextattr
+.Nd set a named extended attribute
+.Sh SYNOPSIS
+.Nm
+.Ar attrnamespace
+.Ar attrname
+.Ar filename
+.Ar attrvalue
+.Sh DESCRIPTION
+.Nm
+is a user tool to set a named extended attribute on a file or directory to
+the provided string.
+The
+.Ar attrnamespace
+argument should be the namespace of the attribute to retrieve: legal
+values are "user" and "system".
+The
+.Ar attrname
+argument should be the name of the attribute,
+.Ar filename
+the name of the file or directory to set the attribute for, and
+.Ar attrvalue
+a string to store in the attribute.
+.Nm
+will store the string in the file's attribute.
+In order for
+.Nm
+to succeed, the attribute service must be available on the file system,
+and appropriate privilege may be required.
+.Sh EXAMPLES
+.Dl # setextattr system md5 /boot/kernel/kernel `md5 -q /boot/kernel/kernel`
+.Pp
+Set the
+.Dq md5
+extended attribute on the file /boot/kernel/kernel to the string
+containing the output of
+.Dq md5 -q /boot/kernel/kernel .
+.Sh SEE ALSO
+.Xr extattr 2 ,
+.Xr extattr 3 ,
+.Xr extattrctl 8 ,
+.Xr getextattr 8 ,
+.Xr extattr 9
+.Sh HISTORY
+Extended attribute support was developed as part of the TrustedBSD Project,
+and introduced in
+.Fx 5.0 .
+It was developed to support security extensions requiring additional labels
+to be associated with each file or directory.
+.Sh AUTHORS
+Robert N M Watson
+.Sh BUGS
+.Nm
+can only be used to set attributes to strings.

+the SPD entries are flushed.
+.It Fl a
+.Nm
+usually does not display dead SAD entries with
+.Fl D .
+If with
+.Fl a ,
+the dead SAD entries will be displayed as well.
+A dead SAD entry means that
+it has been expired but remains
+because it is referenced by SPD entries.

+.Pp
+You must specify the direction of its policy as
+.Ar direction .
+Either
+.Li out
+or
+.Li in
+are used.
+.Li discard
+means the packet matching indexes will be discarded.
+.Li none
+means that IPsec operation will not take place onto the packet.
+.Li ipsec
+means that IPsec operation will take place onto the packet.
+Either
+.Li ah ,
+.Li esp
+or
+.Li ipcomp
+is to be set as
+.Ar protocol .
+.Ar mode
+is either
+.Li transport
+or
+.Li tunnel .
+If
+.Ar mode
+is
+.Li tunnel ,
+you must specify the end-points addresses of the SA as
+.Ar src
+and
+.Ar dst
+with
+.Sq -
+between these addresses which is used to specify the SA to use.
+If
+.Ar mode
+is
+.Li transport ,
+both
+.Ar src
+and
+.Ar dst
+can be omited.
+.Ar level
+is to be one of the following:
+.Li default , use , require
+or
+.Li unique .
+If the SA is not available in every level, the kernel will request
+getting SA to the key exchange daemon.
+.Li default
+means the kernel consults to the system wide default against protocol you
+specified, e.g.\&
+.Li esp_trans_deflev
+sysctl variable, when the kernel processes the packet.
+.Li use
+means that the kernel use a SA if it's available,
+otherwise the kernel keeps normal operation.
+.Li require
+means SA is required whenever the kernel sends a packet matched
+with the policy.
+.Li unique
+is the same to require.
+In addition, it allows the policy to bind with the unique out-bound SA.
+If you use the SA by manual keying,
+you can put the decimal number as the policy identifier after
+.Li unique
+separated by colon
+.Sq \:
+like the following;
+.Li unique:number .
+.Li number
+must be between 1 and 32767.
+It corresponds to
+.Ar extensions Fl u .

+.Sh DESCRIPTION
+The
+.Nm
+utility provides shell level access to the ioctl
+requests served by the handy scanner device driver gsc.
+Please see
+.Xr gsc 4
+for the exact meaning of the requests.  Generally they modify
+the output and behaviour of the gsc scanner device.
+When
+.Nm
+is called with no option only the current settings are reported.
+.Pp
+The following options are available:
+.Bl -tag -width indent
+.It Fl s Bq Dv GSC_SRESSW
+Set the scanner with the values of the resolution selector switch.
+.It Fl q
+Operate in quiet mode, i.e. do not report any of the current settings.
+Normally the parameters are shown after the modifications have been
+performed.
+.It Fl f Ar file
+Operate on a different scanner device node given by filename.
+Note
+that even though there may exist more than one node of scanner device
+several of them will refer the same device unit.
+The modifications are
+performed od the unit regardless of the device node by which it is
+accessed.
+.It Fl r Ar resolution Bq Dv GSC_SRES
+Set the resolution in dpi.
+.It Fl w Ar width Bq Dv GSC_SWIDHT
+Set the width of the bitmap in pixels.
+.It Fl h Ar height Bq Dv GSC_SHEIGHT
+Set the height of the bitmap in lines of pixels.
+.It Fl b Ar len Bq Dv GSC_SBLEN
+Set the internal dma buffer to be
+.Ar len
+lines in size.
+.It Fl t Ar timeout Bq Dv GSC_SBTIME
+Set the timeout time for reading one dma buffer.

+.Sh DESCRIPTION
+.Nm Sicontrol
+is used to configure and monitor the SI/XIO device driver.
+.Pp
+.Nm Sicontrol
+operates on the specified
+.Ar device
+to indicate which port is to be used.
+.Pp
+The special
+.Ar device
+string `-' is used to indicate the global driver settings instead.
+.Pp
+A '/dev/' is included if necessary.
+.Pp
+The following commands are used for the global settings and should be
+specified with the '-' device name.
+.Bl -tag -width 4n
+.It Cm int_throttle Op Cm value
+Configure the `aggregate interrupt throttle value'.
+The maximum number of host adapter interrupts per second is determined by:
+.Pp
+.Ar "controller CPU clock / (8 * int_throttle)"
+.Pp
+The default value at boot time is 25000.  The host adapter cpu clock is
+25Mhz.  This gives a maximum interrupt rate of about 125 interrupts per
+second.
+.Pp
+Lowering this value will increase the rate in which the host adapter can
+interrupt the operating system for attention.
+.\"
+.It Cm rxint_throttle Op Cm value
+Configure the receiver interrupt throttle value.
+The default value of 4 at boot time allows an interrupt rate of
+approximately 25.
+.Pp
+Lowering this value will increase the rate in which the host adapter can
+interrupt the operating system to empty the receiver fifos.
+.\"
+.It Cm nport
+Return the number of ports under the control of the device driver.
+.El
+.Pp
+The following commands are used for the individual ports and should be
+specified with a device name from
+.Pa /dev :
+.Bl -tag -width 4n
+.It Cm mstate
+Show the current incoming modem control signals.
+.It Cm ccbstat
+Show the current "ccb" structure for the specified port.
+This is not of
+much use outside of debugging the driver and determining why a port is
+wedged.
+.It Cm ttystat
+Show the current "tty" structure that the kernel has for the specified port.
+This is not much use outside of debugging the driver.

+.Sh NAME
+.Nm sliplogin
+.Nd attach a serial line network interface
+.Sh SYNOPSIS
+.Nm
+.Op Ar loginname Op Ar device
+.Sh DESCRIPTION
+.Nm Sliplogin
+is used to turn the terminal line on standard input (or
+.Ar device )
+into a Serial Line IP
+.Pq Tn SLIP
+link to a remote host.  To do this, the program
+searches the file
+.Pa /etc/sliphome/slip.hosts
+for an entry matching
+.Ar loginname
+(which defaults to the current login name if omitted).
+If a matching entry is found, the line is configured appropriately
+for slip (8-bit transparent i/o) and converted to
+.Tn SLIP
+line discipline using the optional line discipline parameters.
+.Pp
+The optional line discipline parameters consist of one or more of
+the following;
+.Sq normal ,
+.Sq compress ,
+.Sq noicmp ,
+or
+.Sq autocomp
+which correspond respectively to
+.Sq use normal line discipline
+(no header compression),
+.Sq enable VJ header compression ,
+.Sq throw away ICMP packets ,
+and
+.Sq auto enable VJ header compression
+(only if the remote end of the link also supports it).
+.Pp
+Then a shell script is invoked to initialize the slip
+interface with the appropriate local and remote
+.Tn IP
+address,
+netmask, etc.
+.Pp
+The usual initialization script is
+.Pa /etc/sliphome/slip.login
+but, if particular hosts need special initialization, the file
+.Pa /etc/sliphome/slip.login. Ns Ar loginname
+will be executed instead if it exists.
+The script is invoked with the parameters
+.Bl -tag -width slipunit
+.It Em slipunit
+The unit number of the slip interface assigned to this line.  E.g.,
+.Sy 0
+for
+.Sy sl0 .
+.It Em speed
+The speed of the line.
+.It Em args
+The arguments from the
+.Pa /etc/sliphome/slip.hosts
+entry, in order starting with
+.Ar loginname .
+.El
+.Pp
+Only the super-user may attach a network interface.  The interface is
+automatically detached when the other end hangs up or the
+.Nm
+process dies.  If the kernel slip
+module has been configured for it, all routes through that interface will
+also disappear at the same time.  If there is other processing a site
+would like done on hangup, the file
+.Pa /etc/sliphome/slip.logout
+or
+.Pa /etc/sliphome/slip.logout. Ns Ar loginname
+is executed if it exists.  It is given the same arguments as the login script.
+.Ss Format of /etc/sliphome/slip.hosts
+Comments (lines starting with a `#') and blank lines (or started
+with space) are ignored.
+Other lines must start with a
+.Ar loginname
+but the remaining arguments can be whatever is appropriate for the
+.Pa  slip.login
+file that will be executed for that name.
+Arguments are separated by white space and follow normal
+.Xr sh 1
+quoting conventions (however,
+.Ar loginname
+cannot be quoted).
+Usually, lines have the form
+.Bd -literal -offset indent
+loginname local-address remote-address netmask opt-args
+.Ed
+.Pp
+where
+.Em local-address
+and
+.Em remote-address
+are the IP host names or addresses of the local and remote ends of the
+slip line and
+.Em netmask
+is the appropriate IP netmask.  These arguments are passed
+directly to
+.Xr ifconfig 8 .
+.Em Opt-args
+are optional arguments used to configure the line.
+.Sh FreeBSD Additions
+An additional SLIP configuration file (if present) is
+.Pa /etc/sliphome/slip.slparms .
+If particular hosts need different configurations, the file
+.Pa /etc/sliphome/slip.slparms. Ns Ar loginname
+will be parsed instead if it exists.
+.Ss Format of /etc/sliphome/slip.slparms*
+Comments (lines starting with a `#') and blank lines (or started with
+space) are ignored.
+This file contains from one to three numeric parameters separated with spaces,
+in order:
+.Ar keepalive ,
+.Ar outfill
+and
+.Ar slunit .
+.Bl -tag -width keepalive
+.It Ar keepalive
+Set SLIP "keep alive" timeout in seconds.
+If FRAME_END is not received in
+this amount of time,
+.Nm
+closes the line and exits.
+The default value is no timeout (zero).
+.It Ar outfill
+Set SLIP "out fill" timeout in seconds.
+It forces at least one FRAME_END
+to be sent during this time period, which is necessary for the "keep alive"
+timeout on the remote side.
+The default value is no timeout (zero).
+.It Ar slunit
+Set the SLIP unit number directly.
+Use with caution, because no check is made
+for two interfaces with same number.
+By default sliplogin dynamically assigns the unit number.
+.El
+.Pp
+If latter two parameters are omitted, they will not affect the
+corresponding SLIP configuration.
+If any of first two parameters is equal to zero, it will not affect
+the corresponding SLIP configuration.
+.Sh EXAMPLES
+The normal use of
+.Nm
+is to create a
+.Pa /etc/passwd
+entry for each legal, remote slip site with
+.Nm
+as the shell for that entry.  E.g.,
+.Bd -literal
+Sfoo:ikhuy6:2010:1:slip line to foo:/tmp:/usr/sbin/sliplogin
+.Ed
+.Pp
+(Our convention is to name the account used by remote host
+.Ar hostname
+as
+.Em Shostname . )
+Then an entry is added to
+.Pa slip.hosts
+that looks like:
+.Pp
+.Bd -literal -offset indent -compact
+Sfoo	`hostname`	foo	netmask
+.Ed
+.Pp
+where
+.Em `hostname`
+will be evaluated by
+.Xr sh
+to the local host name and
+.Em netmask
+is the local host IP netmask.
+.Pp
+Note that
+.Nm
+must be setuid to root and, while not a security hole, moral defectives
+can use it to place terminal lines in an unusable state and/or deny
+access to legitimate users of a remote slip line.  To prevent this,
+.Nm
+is installed as user
+.Em root ,
+group
+.Em network
+and mode 4550 so that only members of group
+.Em network
+may run
+.Nm .
+The system administrator should make sure that all legitimate users
+are a member of the correct group.
+.Sh DIAGNOSTICS
+.Nm Sliplogin
+logs various information to the system log daemon,
+.Xr syslogd 8 ,

+.Em daemon .

+ * It sets the line discipline to slip, invokes a shell script to initialize
+ * the network interface, then pauses forever waiting for hangup.
+ *
+ * It is a remote descendant of several similar programs with incestuous ties:
+ * - Kirk Smith's slipconf, modified by Richard Johnsson @ DEC WRL.
+ * - slattach, probably by Rick Adams but touched by countless hordes.
+ * - the original sliplogin for 4.2bsd, Doug Kingston the mover behind it.
+ *
+ * There are two forms of usage:
+ *
+ * "sliplogin"
+ * Invoked simply as "sliplogin", the program looks up the username
+ * in the file /etc/slip.hosts.
+ * If an entry is found, the line on fd0 is configured for SLIP operation
+ * as specified in the file.
+ *
+ * "sliplogin IPhostlogin </dev/ttyb"
+ * Invoked by root with a username, the name is looked up in the
+ * /etc/slip.hosts file and if found fd0 is configured as in case 1.

+.Sh NAME
+.Nm slstat
+.Nd report serial line IP statistics
+.Sh SYNOPSIS
+.Nm
+.Op Fl i Ar interval
+.Op Fl vr
+.Op Ar unit
+.Sh DESCRIPTION
+The
+.Nm
+utility
+reports certain kernel statistics kept about serial line internet
+protocol traffic.
+.Pp
+The options are as follows:
+.Bl -tag -width indent
+.It Fl i
+Repeat the display indefinitely every
+.Ar interval
+seconds.
+If no
+.Ar interval
+is specified, the default is 5 seconds.
+.It Fl v
+Verbose display of extra fields of information.
+.It Fl r
+Display all values in rate per second rather than amount per interval.
+.It Ar unit
+Is number specifying the
+.Tn SLIP
+interface, or a
+.Tn SLIP
+interface name.
+The default unit is
+.Sy 0
+for interface
+.Sy sl0 .
+.El
+.Pp
+By default,
+.Nm
+displays the following information:
+.Pp
+.Bl -tag -width indent
+.It in
+bytes received
+.It out
+bytes sent
+.It pack
+packets received or sent
+.It comp
+compressed packets received or sent
+.It uncomp
+uncompressed packets received or sent
+.It unknwn
+inbound packets of unknown type
+.It toss
+inbound packets tossed because of error
+.It other
+all other inbound or outbound ip packets
+.It err
+input or output errors
+.It search
+searches for connection state
+.It miss
+times we could not find a connection state
+.It coll
+collisions with end of clists.
+If you get many collisions (more than one or two
+a day) you probably do not have enough clists
+and you should increase
+.Dv nclist
+in param.c.
+.El
+.Sh EXAMPLES
+The command:
+.Dl slstat -i 5
+will print what the system is doing every five
+seconds.

+.Sh NAME
+.Nm spray
+.Nd send many packets to host
+.Sh SYNOPSIS
+.Nm
+.Op Fl c Ar count
+.Op Fl d Ar delay
+.Op Fl l Ar length
+.Ar host
+.Sh DESCRIPTION
+.Nm Spray
+sends multiple RPC packets to
+.Ar host
+and records how many of them were correctly received and how long it took.
+.Pp
+The options are as follows:
+.Bl -tag -width indent
+.It Fl c Ar count
+Send
+.Ar count
+packets.
+.It Fl d Ar delay
+Pause
+.Ar delay
+microseconds between sending each packet.
+.It Fl l Ar length
+Set the length of the packet that holds the RPC call message to
+.Ar length
+bytes.
+Not all values of
+.Ar length
+are possible because RPC data is encoded using XDR.
+.Nm Spray
+rounds up to the nearest possible value.
+.El
+.Pp
+.Nm Spray
+is intended for use in network testing, measurement, and management.
+This command
+.Em "can be very hard on a network and should be used with caution" .

+.Sh NAME
+.Nm stl ,
+.Nm stli
+.Nd "drivers for Stallion Technologies multiport serial controllers"
+.Sh SYNOPSIS
+.Cd "stl0 at isa? port <addr> tty irq <irq>"
+.Cd "stli0 at isa? port <io-addr> tty iomem <mem-addr> iosiz <size> flags <type> "
+.Cd "stli0 at eisa? port <io-addr> tty iomem <mem-addr> iosiz <size> flags <type> "
+.Sh DESCRIPTION
+This is a kernel driver for Stallion Technologies multiport serial boards.
+There are two drivers, each supporting a different class of boards.
+The
+.Nm
+driver supports the EasyIO and EasyConnection 8/32
+boards, while the
+.Nm stli
+driver supports all other types, including
+ONboard, Brumby and EasyConnection 8/64.
+.Sh CONFIGURATION
+Each board installed in the system needs a configuration entry in the
+kernel configuration file.
+Slightly different options and parameters are required for each of the
+different board types.
+Depending on the type of board one of the
+.Nm
+or
+.Nm stli
+drivers will be used.  The
+.Nm
+and
+.Nm stli
+drivers can support up to 8 boards.
+.Pp
+Configuration of the hardware - DIP switches, jumpers, etc - varies
+from board to board.
+Consult documentation supplied with the board for hardware
+configuration details.
+Alternatively the board documentation is available on Stallion
+Technologies WWW site at http://www.stallion.com.
+.Pp
+The EasyIO and EasyConnection 8/32 families of boards use the
+.Nm
+driver.
+ISA board configuration entries for the
+.Nm
+driver take the general form of:
+.Pp
+.Cd "stlX at isa? port <io-addr> tty irq <irq>"
+.Pp
+.Ar X
+is the unit number assigned to the board.
+Any unique value between 0 and 7 is valid.
+.Pp
+The I/O address used by the board is specified by
+.Ar <io-addr> .
+Each of the EasyIO and EasyConnection 8/32-AT boards can use
+an I/O address in the range from 0 to 0x400.
+.Pp
+All EasyIO and EasyConnection 8/32 boards require an interrupt,
+and this interrupt is specified by
+.Ar <irq> .
+Legal IRQ values for the ISA boards are 3, 4, 5, 7, 10, 11, 12 and 15.
+Interrupts are software programmed on all boards except the EasyIO-8M.
+.Pp
+The EasyConnection 8/32-AT board uses a secondary I/O address region,
+and this is fixed at address 0x280 in the driver code.
+All EasyConnection 8/32-AT boards may share the same secondary address
+region.
+.Pp
+EasyConnection 8/32 PCI boards are detected automatically by the
+system on boot up.
+No configuration information is required in advance for these
+board types.
+During boot up the
+.Nm
+driver will issue messages to indicate that a EasyConnection 8/32
+PCI board was found, and some information about it.
+.Pp
+Following are some examples of configuration entries for each of the ISA
+boards supported by the
+.Nm
+driver.
+Each example also describes some important details about each of the
+board types.
+.Pp
+Each EasyIO board requires 8 bytes of I/O address space and 1 IRQ line.
+A configuration entry for an EasyIO board would look like:
+.Pp
+.Cd "stl0 at isa? port 0x2a8 tty irq 15"
+.Pp
+This entry specifies an EasyIO board at I/O address 0x2a8 using IRQ 15.
+The I/O and IRQ values can be modified as required.
+.Pp
+Each EasyConnection 8/32-AT board requires 2 sets of I/O addresses
+and 1 IRQ line.
+The primary I/O address range is 2 bytes in size, and must be unique
+to each EasyConnection 8/32-AT board in the system.
+The secondary I/O address range is 32 bytes in size, but can be shared
+by multiple EasyConnection 8/32-AT boards.
+This secondary I/O address is set at 0x280 in the driver code.
+A configuration entry would look like:
+.Pp
+.Cd "stl0 at isa? port 0x2a0 irq 10 tty"
+.Pp
+This specifies an EasyConnection 8/32-AT with primary I/O address 0x2a0,
+secondary I/O address of 0x280 and IRQ 10.
+.Pp
+The ONboard, Brumby and EasyConnection 8/64 families of boards use the
+.Nm stli
+driver.  The
+.Nm stli
+driver supports the ISA and EISA members of these families.
+.Pp
+ISA board configuration entries for the
+.Nm stli
+driver take the general form of:
+.Pp
+.Cd "stliX at isa? port <io-addr> tty iomem <mem-addr> iosiz <size> flags <type>"
+.Pp
+.Ar X
+is the unit number assigned to the board.
+Any unique value between 0 and 7 is valid.
+.Pp
+The I/O address used by the board is specified by
+.Ar <io-addr> .
+Each of the different supported board types has restrictions on valid
+I/O addresses and also the amount of I/O space required varies between
+the boards.
+.Pp
+All boards using the
+.Nm stli
+driver require a shared memory region to operate.
+Depending on the board type the region required varies in size
+from 4 kbytes to 64 kbytes.  The size of the board region is specified
+by field
+.Ar <size>
+of the configuration entry, and the address of the region is specified by
+.Ar <mem-addr> .
+.Pp
+The flags field specifies the particular board type that this entry
+applies to.
+Not all board types are distinguishable by the driver at runtime,
+so this field is required by the driver.
+Valid board types are:
+.Bd -literal -offset indent
+BOARD NAME			TYPE	I/O SIZE
+
+Brumby				  2	0x4000
+ONboard				  4	0x10000
+ONboard/E			  7	0x10000
+EasyConnection 8/64-AT		 23	0x1000
+EasyConnection 8/64-EISA	 24	0x10000
+.Ed
+.Pp
+Following are some examples of configuration entries for each of the
+boards supported by the
+.Nm stli
+driver.
+Each example also describes some important details about
+each of the board types.
+.Pp
+The EasyConnection 8/64-AT board requires 4 bytes of I/O address space and
+4 kbytes of memory space.
+A configuration entry would look like:
+.Pp
+.Cd "stli0 at isa? port 0x2a0 tty iomem 0xcc000 iosiz 0x1000 flags 23"
+.Pp
+The flags field of this entry specifies that this is an
+EasyConnection 8/64-AT board.
+It is set to I/O address 0x2a0 and memory address 0xcc000.
+The
+.Ar iosiz
+parameter specifies a memory region size
+of 4 kbytes.
+.Pp
+The EasyConnection 8/64-EISA board requires a 64 kbyte region of
+memory space.
+This region can be anywhere in the 32 bit memory address space.
+A configuration entry would be like:
+.Pp
+.Cd "stli0 at eisa? port 0x2000 tty iomem 0x80000000 iosiz 0x10000 flags 24"
+.Pp
+The flags field is used to specify that this is an EasyConnection 8/64-EISA
+board.
+The I/O (port) address resource is derived from the EISA slot that
+the board is in.
+Each EISA slot is allocated a section of the I/O address space by the
+hardware of the system.
+That address being 0xX000 where X is the slot number.
+The example board is at memory address 0x80000000 which is 2 Gbyte.
+The
+.Ar iosiz
+parameter specifies the size of the memory region,
+in this case 64 kbytes.
+.Pp
+Each ONboard ISA board requires 16 bytes of I/O space and a 64 kbyte
+section of memory address space.
+Valid ONboard I/O addresses are in the range 0x200 to 0x300.
+A configuration entry for an ONboard ISA would look like:
+.Pp
+.Cd "stli0 at isa? port 0x240 tty iomem 0xd0000 iosiz 0x10000 flags 4"
+.Pp
+This entry specifies an ONboard ISA by setting flags to 4.
+It uses I/O address 0x240 and a memory region of 64 kbytes at memory
+address 0xd0000.
+.Pp
+Each ONboard/E board requires a 64 kbyte memory region, and this
+can be anywhere in the 32 bit address space (that is from 0 to 4 Gbyte).
+A configuration entry would look like:
+.Pp
+.Cd "stli0 at eisa? port 0x3000 tty iomem 0xc0000000 iosiz 0x10000 flags 7"
+.Pp
+The specifies an ONboard/E in slot 3 using a shared memory address
+of 0xc0000000 (3 Gbyte).
+.Pp
+Each Brumby board requires 16 bytes of I/O address space and a 4 kbyte
+region of shared memory space.
+The valid Brumby I/O addresses are in the range 0x300 to 0x400.
+The shared memory region of the Brumby must be in the 0xc0000 to
+0xdc000 region of the memory address space.
+A configuration entry for a Brumby would be like:
+.Pp
+.Cd "stli0 at isa? port 0x360 tty iomem 0xc8000 iosiz 0x4000 flags 2"
+.Pp
+This specifies a Brumby board at I/O address 0x360 using a shared memory
+region at address 0xc8000.
+.Sh NOTES
+When building the device nodes for the ports be sure to use the correct
+driver name,
+.Nm
+or
+.Nm stli .
+Each driver has a separate major number allocated,
+so even though the port device names are the same for each driver,
+the major number of the device node is different.
+Use the
+.Xr MAKEDEV 8
+script to create the devices.
+Use the ttyE and cue tag for the
+.Nm
+driver, and
+the ttyEi and cuei tags for the
+.Nm stli
+driver.
+.Pp
+The intelligent board types (ONboard, Brumby and EasyConnection 8/64)
+require a firmware download before the ports will be operational.
+This is achieved by using the
+.Nm stlload
+command.
+See its manual page for details on usage.

+.Op Fl vhVR
+.Op Fl i Ar image-file
+.Op Fl c Ar control-device
+.Op Fl r Ar rx-buf-size
+.Op Fl t Ar tx-buf-size
+.Op Fl B Ar boot-banner
+.Op Fl b Ar unit-number
+.Sh DESCRIPTION
+.Nm Stlload
+is used to download the firmware code to Stallion Technologies intelligent
+multiport serial boards.
+A firmware download is only required for those boards that use the Stallion
+.Nm stli
+driver.
+This includes the EasyConnection 8/64, ONboard and Brumby families of boards.
+.Pp
+Different board types require different firmware images.
+If the wrong firmware is loaded into a board it will fail to operate.
+.Pp
+The Stallion EasyConnection 8/64 Host Adapter PCI cards DO NOT require
+firmware to be loaded.
+.Pp
+The download process is achieved through the Stallion
+.Nm stli
+driver control device,
+.Pa /dev/staliomem? .
+This device implements a file type device that can read and write into the
+boards shared memory region.
+It also implements a number of special
+.Em ioctls
+that reset and restart the board.
+.Pp
+The options are:
+.Bl -tag -width indent
+.It Fl v
+Verbose output generation.
+Trace is generated at each phase of the download and startup process.
+.It Fl h
+Output usage information.
+.It Fl V
+Output version information.
+.It Fl R
+Reset the board only.
+Does not proceed to download firmware to the board.
+.It Fl i Ar image-file
+Specify the firmware image file to download.
+The default firmware image is
+.Pa /usr/libdata/stallion/cdk.sys .
+.It Fl c Ar control-device
+Specify the board control device through which to download the firmware
+and start up the board.
+The default is
+.Pa /dev/staliomem0 .
+.It Fl r Ar rx-buf-size
+Specify the size of the boards shared memory Receive Data buffer.
+By default the buffer is dynamically sized to use the maximum
+available shared memory.
+.It Fl t Ar tx-buf-size
+Specify the size of the boards shared memory Transmit Data buffer.
+By default the buffer is dynamically sized to use the maximum
+available shared memory.
+.It Fl B Ar boot-banner
+Enable the slave debug trace flag during download.
+This enables debug trace output from the firmware code.
+This trace is output on port 0 of the board,
+and the port is set to 9600 baud, 8 data bits, no parity and 1 stop bit.
+.It Fl b Ar unit-number
+Specify the unit (board) number to be downloaded.  The default is to
+download board 0.

+.Sh NAME
+.Nm stlstats
+.Nd "Stallion Technologies multiport serial statistics display"
+.Sh SYNOPSIS
+.Nm
+.Op Fl hVi
+.Op Fl c Ar control-device
+.Op Fl b Ar board-number
+.Op Fl p Ar port-number
+.Op Fl d Ar port-device
+.Sh DESCRIPTION
+.Nm Stlstats
+is used to display statistical information about the ports on Stallion
+Technologies multiport serial boards.
+.Pp
+.Nm Stlstats
+normally runs as a full screen menu driven application.
+A help line is displayed at the bottom of each screen with the valid
+input keys for this screen.
+.Pp
+Generally the digit keys ('0' through '9') specify the number of the
+device to display statistics for.
+Where digits alone are not enough to access all possible devices
+(for example on 16 port panels) then the first letters of the alphabet
+are used to access the remaining devices.
+The letters 'a' through 'f' are used to access devices 10 through 15.
+.Pp
+The 'q' key is always used to move back to the previous level screen.
+The escape key can also be used to move back to the previous screen.
+.Pp
+The first screen is a display of all ports on panel 0 of board 0.
+Values displayed on this screen are a summary of the information for
+each port.  The statistics displayed are: driver and TTY state flags,
+termios flags (cflags, iflags, oflags, lflags), RS-232 signal values
+(as per TIOCM signal defines), total transmit and receive character
+counts.
+.Pp
+From this screen you can look at summary information
+about each panel and board installed in the system.
+Each board is accessed by the digit keys ('0' through '7'),
+while panels of each board can be cycled through using the 'n' key.
+.Pp
+The per port screen displays some detailed information about a
+particular port.
+This is accessed from the board screen using the 'p' key.
+The first port displayed will be port 0.
+To display other ports use the digit and alphabetic keys
+('0' through '9' and 'a' through 'f').
+This screen displays: driver and TTY state flags, hardware ID,
+termios flags (cflags, iflags, oflags, lflags),
+total transmitted and received character counts,
+current transmit and receive characters buffered,
+receiver error counts (overruns, parity, framing, lost),
+software flow control characters transmitted and received,
+hardware flow control actions taken,
+count of transmitted and received breaks,
+modem signal transitions and
+current RS-232 signal states.
+.Pp
+The options are:
+.Bl -tag -width indent
+.It Fl h
+Output usage information.
+.It Fl V
+Output version information.
+.It Fl i
+Output only the board type information.
+This output is useful for scripts or other programs that need to know
+a little bit about the board (for example an automated download script).
+.Nm Stlstats
+will not enter full screen interactive mode.
+.It Fl c Ar control-device
+Specify the board control device through which to gather port statistics.
+The default is
+.Pa /dev/staliomem0 .
+.It Fl b Ar board-number
+Specify the board number to display first.
+The default is to display board 0.
+.It Fl p Ar port-number
+Specify the port number to display first.
+.Nm Stlstats
+will go straight into the port display screen (bypassing board display)
+when this option is used.
+.It Fl d Ar port-device
+Specify the port special device file (the
+.Pa /dev/ttyXXX
+file) to
+display first.
+The board screen is bypassed and the port statistics screen is shown
+immediately on start up.

+DISTRIBUTION INFORMATION
+------------------------
+
+An ``X-'' prefixed before a distribution set means that the XFree86
+base distribution, libraries, manual pages, SVGA server and a set
+of default fonts will be selected in addition to the set itself.
+If you select such a set, you will also be presented with a set of
+menus for customizing the selections to your desired X Window System
+setup.
+
+Any distribution may be further customized by selecting the `Custom'
+item before leaving the menu.
+
+N.B. All references in this document to `complete source' mean the
+complete source tree minus any legally encumbered cryptography code.
+
+The current "canned" installations are provided:
+
+Developer:      Base ("bin") distribution, man pages, dictionary
+                files, profiling libraries and the complete source tree.
+
+Kern-Developer: As above, but with only kernel sources instead of
+                the complete source tree.
+
+User:           The base distribution, man pages, dictionary files and
+                the FreeBSD 1.x, 2.0, 2.1.x, 2.2.x and 3.x compatibility sets.
+
+Minimal:        Only the base distribution.
+
+Everything:     The base distribution, man pages, dictionary files,
+                profiling libraries, the FreeBSD compatibility libraries,
+                the complete source tree, games and your choice of XFree86
+                distribution components.
+
+                Note that the cryptography source code is NOT included
+                in this collection.  You will need to select that by
+                hand if you're inside the United States.
+
+Custom:         Allows you to create or modify your distribution set on
+                a piece-by-piece basis.
+
+Reset:          Clear all currently selected distributions.

+Boot Manager Selection:
+-----------------------
+
+If you wish to switch between multiple operating systems on your
+machine, or if you are trying to install FreeBSD on a drive other than
+your 1st drive, then you must install a boot manager.  In the case
+where you wish to boot off an alternate drive, it should also be noted
+that you still need to install a boot manager on the FIRST drive!
+Even if you do not intend to create a FreeBSD partition on that drive
+(e.g. it's being wholly used by something else), the boot manager
+still needs to reside on the first disk in order to function as a
+"redirector" for the boot process.
+
+To do this, simply select your 1st drive in the drive selection menu
+and when the partition editor comes up, don't make any changes - just
+(Q)uit.  At the boot manager menu which follows, select the first
+option (install a boot manager) and then proceed to setup the other
+drive(s) for FreeBSD as normal.
+
+It should also be noted that "operating systems" such as Windows 95
+will completely overwrite your boot manager without so much as a
+polite "may I please destroy your boot manager?" prompt if you make
+the mistake of installing them second.  If this happens to you after
+FreeBSD is already installed, all is not lost!  Simply revisit your
+FreeBSD distribution directory and look for a tools/ subdirectory, in
+which you'll find "bootinst.exe" and "boot.bin".  To reinstall, simply
+say "bootinst boot.bin" while in the tools/ subdirectory.
+
+
+If you see the boot manager displaying ``F?'' when you try to come up
+for the first time and it refuses to change, no matter how often you
+whap on the function key assigned to FreeBSD, then you have a geometry
+mismatch problem and you should read the next section for important
+information on how to prevent that exact problem from happening!
+
+
+Geometry Translation / Sharing the disk(s) with another OS:
+----------------------------------------------------------
+
+If you are going to actually install some portion of FreeBSD on a
+drive then PLEASE BE VERY CERTAIN that the Geometry reported in the
+Partition Editor is the correct one for your drive and controller
+combination!
+
+IDE drives often have a certain geometry set during the PC BIOS setup,
+or (in the case of larger IDE drives) have their geometry "translated"
+by either the IDE controller or a special boot-sector translation
+utility such as that by OnTrack Systems.  In these cases, knowing the
+correct geometry gets even more complicated as it's not something you
+can easily tell by looking at the drive or the PC BIOS setup.  The
+best way of verifying that your geometry is being correctly calculated
+in such situations is to boot DOS (from the hard disk, not a floppy!)
+and run the ``pfdisk'' utility provided in the tools/ subdirectory of
+the FreeBSD CDROM or FTP site.  It will report the geometry that DOS
+sees, which is generally the correct one.

+If you have no DOS partition sharing the disk at all, then you may
+find that you have better luck with Geometry detection if you create a
+very small DOS partition first, before installing FreeBSD.  Once
+FreeBSD is installed you can always delete it again if you need the
+space.
+
+It's actually not a bad idea (believe it or not) to have a small
+bootable DOS partition on your FreeBSD machine anyway: Should the
+machine become unstable or exhibit strange behavior at some point in
+the future (which is not uncommon behavior for PC hardware!) you can
+then at least use DOS for installing and running one of the
+commercially available system diagnostic utilities.
+
+IMPORTANT NOTE:
+
+Any root partition you try to boot from must also reside below the
+1024th cylinder.  If you're using a translated geometry then this is
+probably not a problem, but if you are using a native disk geometry
+which exceeds 1024 cylinders then you could have a failure to boot if
+you end up installing a root partition (or even just the kernel file
+in a root partition) out past cylinder 1024.  If you are trying to
+share your first disk with FreeBSD and another OS which was installed
+previously, you are particularly susceptible to this problem and should
+check your disk addresses very carefully.
+
+If you find that you have insufficient space below cylinder 1024 to
+make a root partition for FreeBSD (and again, this ONLY applies to the
+root partition - once FreeBSD's kernel is loaded, it doesn't care
+about the geometry issues) then you will probably need to install on a
+completely different disk (see the boot manager section above) or
+resize your existing partitions so that both operating systems can
+have boot partitions below cylinder 1024.
+
+You may blame IBM for the limitations of a 10 bit cylinder address.
+"No one will have a disk with more than 1024 cylinders." I'm sure
+someone said.

+            you may invoke FTP in "Active" mode, "Passive" mode, or
+            via an HTTP proxy.
+
+            Active mode is the standard way of fetching files and

+You can do network installations over 3 types of communications links:
+
+        Serial port:    SLIP / PPP
+        Parallel port:  PLIP (laplink cable)
+        Ethernet:       A standard Ethernet controller (includes some
+                        PCMCIA networking cards).
+
+SLIP support is rather primitive and limited primarily to directly
+connected links, such as a serial cable running between a laptop
+computer and another PC.  The link must be hard-wired as the SLIP
+installation doesn't currently offer a dialing capability (that
+facility is offered by the PPP utility, which should be used in
+preference to SLIP whenever possible).  When you choose the SLIP
+option, you'll be given the option of later editing the slattach
+command before it's run on the serial line.  It is expected that
+you'll run slattach (or some equivalent command) on the other end of
+the link at that time and bring up the line.  FreeBSD will then
+install itself at serial speeds of up to 115.2K/baud (the recommended
+speed for a hardwired cable).
+
+If you're using a modem then PPP is almost certainly your only choice.
+Make sure that you have your service provider's information handy as
+you'll need to know it fairly early in the installation process.  You
+will need to know your service provider's IP address, the IP address 
+of your provider's DNS server, and possibly your own IP address unless
+your ISP supports dynamic negotiation, most do.  If you do not choose
+a PAP or CHAP login you will also need to know how to use the various
+"AT commands" to dial the ISP with your particular brand of modem as
+the PPP dialer provides only a very simple terminal emulator and has no
+"modem capabilities database".  If you choose a PAP or CHAP login you
+can simply enter `dial' (without the quotes) at the ppp prompt if your
+modem uses the Hayes compatible AT command set.
+
+If a hard-wired connection to another FreeBSD (2.0R or later) machine
+is available, you might also consider installing over a "laplink"
+parallel port cable.  The data rate over the parallel port is much
+higher than what is typically possible over a serial line, and speeds
+of over 50KB/sec are not uncommon.
+
+Finally, for the fastest possible network installation, an Ethernet
+adaptor is always a good choice!  FreeBSD supports most common PC
+Ethernet cards, a table of which is provided in the FreeBSD Hardware
+Guide (see the Documentation menu on the boot floppy).  If you are
+using one of the supported PCMCIA Ethernet cards, also be sure that
+it's plugged in _before_ the laptop is powered on!  FreeBSD does not,
+unfortunately, currently support "hot insertion" of PCMCIA cards.
+
+You will also need to know your IP address on the network, the
+"netmask" value for your address class, and the name of your machine.
+Your system administrator can tell you which values to use for your
+particular network setup.  If you will be referring to other hosts by
+name rather than IP address, you'll also need a name server and
+possibly the address of a gateway (if you're using PPP, it's your
+provider's IP address) to use in talking to it.  If you do not know
+the answers to all or most of these questions then you should really
+probably talk to your system administrator FIRST before trying this
+type of installation!  Choosing the wrong IP address on a busy network
+will NOT make you popular with your systems administrator!  :-)

+The following options may be set from this screen.  Use the SPACE key
+to toggle an option's value, Q to leave when you're done.
+
+NFS Secure:   NFS server talks only on a secure port
+
+    This is most commonly used when talking to Sun workstations, which
+    will not talk NFS over "non privileged" ports.
+
+
+NFS Slow:     User is using a slow PC or Ethernet card
+
+    Use this option if you have a slow PC (386) or an Ethernet card
+    with poor performance being "fed" by NFS on a higher-performance
+    workstation.  This will throttle the workstation back to prevent
+    the PC from becoming swamped with data.
+
+
+Debugging:    Turn on the extra debugging flag
+
+    This turns on a lot of extra noise over on the second screen
+    (ALT-F2 to see it, ALT-F1 to switch back).  If your installation
+    should fail for any reason, PLEASE turn this flag on when
+    attempting to reproduce the problem.  It will provide a lot of
+    extra debugging at the failure point and may be very helpful to
+    the developers in tracking such problems down!
+
+
+Yes To All:   Assume "Yes" answers to all non-critical dialogs
+
+    This flag should be used with caution.  It will essentially
+    decide NOT to ask the user about any "boundary" conditions that
+    might not constitute actual errors but may be warnings indicative
+    of other problems.  It's most useful to those who are doing unattended
+    installs.
+
+
+FTP username:  Specify username and password instead of anonymous.
+
+    By default, the installation attempts to log in as the
+    anonymous user.  If you wish to log in as someone else,
+    specify the username and password with this option.
+
+
+Install Root:  Specify some directory other than / as your "root".
+
+    This should be left as / unless you have a really good reason to
+    change it.  One good reason might be if you were installing to a
+    disk other than your own, as might happen if you needed to prepare a
+    disk for another machine which couldn't load FreeBSD directly
+    for some reason.
+
+    Note:  If you set this option, you will only be able to install
+    packages if the bin distribution is also installed (usually
+    the case anyway) since /usr/sbin/pkg_add will otherwise not be
+    found after the chroot() call.
+
+
+Editor:  Specify which screen editor to use.
+
+   At various points during the installation it may be necessary
+   to customize some text file, at which point the user will be
+   thrown unceremoniously into a screen editor.  A relatively
+   simplistic editor which shows its command set on-screen is
+   selected by default, but UNIX purists may wish to change this
+   setting to /usr/bin/vi
+
+
+Tape Blocksize:  Specify block size in 512 byte blocks of tape.
+
+    This defaults to 20 blocks, which should work with most
+    tape drive + tar combinations.  It may not allow your particular
+    drive to win any records for speed, however, and the more
+    adventurous among you might try experimenting with larger sizes.
+
+
+Extract Detail:  How to show filenames on debug screen as they're extracted.
+
+    While a distribution is being extracted, the default detail level
+    of "high" will show the full file names as they're extracted.
+    If you would prefer a more terse form for this, namely dots, select
+    the "medium" detail level.  If you want nothing to be printed
+    on the debugging screen during extraction, select "low".
+
+
+Release Name:  Which release to attempt to load from installation media.
+
+    You should only change this option if you're really sure you know
+    what you are doing!  This will change the release name used by
+    sysinstall when fetching components of any distributions, and
+    is a useful way of using a more recent installation boot floppy
+    with an older release (say, on CDROM).
+
+
+Browser Package:  Which package to load for an HTML browser.
+
+    By default, this is set to links but may also be set to any other
+    text capable HTML browser for which a package exists.  If you set this
+    to an X based browser, you will not be able to use it if you're running
+    in text mode! :)
+
+
+Browser Exec:  Which binary to run for the HTML browser.
+
+    The full pathname to the main executable in Browser Package
+
+
+Media Type:   Which media type is being used.
+
+    This is mostly informational and indicates which media type (if any)
+    was last selected in the Media menu.  It's also a convenient short-cut
+    to the media menu itself.
+
+
+Package Temp:  Where package temporary files should go
+
+   Some packages, like emacs, can use a LOT of temporary space - up to
+   20 or 30MB.  If you are going to configure a small / directory (and
+   hence a small /tmp) then you may wish to set this to point at another
+   location (say, /usr/tmp).
+
+
+Use Defaults:  Use default values.
+
+    Reset all options back to their default values.

+This is the FreeBSD DiskLabel Editor.
+
+NOTE: If you're entering this editor from the update procedure then
+you probably shouldn't (C)reate anything at all but rather use only
+the (M)ount command to check and mount existing partitions for
+upgrading.
+
+If you would like the label editor to do most of the following for
+you, simply type `A' for automatic partitioning of the disk.
+
+If you wish to create partitions manually you may do so by moving the
+highlighted selection bar with the arrow keys over the FreeBSD
+partition(s) displayed at the top of the screen.  Typing (C)reate
+while a partition with available free space is selected will allow you
+to create a BSD partition inside of it using some or all of its
+available space.
+
+Typing (M)ount over an existing partition entry (displayed in the
+middle of the screen) will allow you to set a mount point for it
+without initializing it.  If you want it initialized, use the (T)oggle
+command to flip the Newfs flag.  When Newfs is set to "Y", the
+filesystem in question will be ERASED and rebuilt from scratch!
+
+
+You should use this editor to create at least the following
+filesystems:
+
+        Name    Purpose                 Min Size?       Optional?
+        ----    -------                 ---------       ---------
+        /       Root filesystem         20MB            No
+        swap    Swap space              2 * MEM         No
+        /usr    System & user files     80MB or more    Yes
+
+Note: If you do not create a /usr filesystem then your / filesystem
+will need to be bigger - at least 100MB.  This is not recommended as
+any media errors that may occur during disk I/O to user files will
+corrupt the filesystem containing vital system files as well.  It is
+for this reason that / is generally kept on its own filesystem, where
+it should be considered essentially "read only" in your administration
+of it.
+
+Swap space is a little tricker, and the rule of "2 * MEM" is simply a
+best-guess approximation and not necessarily accurate for your
+intended usage of the system.  If you intend to use the system heavily
+in a server or multi-user application, you may be well advised to
+increase this size.  You may also create swap space on multiple drives
+for a larger "total" swap and this is, in fact, recommended if you
+have multiple, fast drives for which such load-balancing can only help
+overall I/O performance.
+
+The /usr filesystem should be sized according to what kind of
+distributions you're trying to load and how many packages you intend
+to install in locations like /usr/local.  You can also make /usr/local
+a separate filesystem if you don't want to risk filling up your /usr
+by mistake.
+
+Another useful filesystem to create is /var, which contains mail, news
+printer spool files and other temporary items.  It is a popular
+candidate for a separate partition and should be sized according to
+your estimates of the amount of mail, news or spooled print jobs that
+may be stored there.
+
+WARNING: If you do not create a separate filesystem for /var, space
+for such files will be allocated out of the root (/) filesystem
+instead.  You may therefore wish to make the / partition bigger if you
+expect a lot of mail or news and do not want to make /var its own
+partition.
+
+If you're new to this installation, you might also want to read the
+following explanation of how FreeBSD's new "slice" paradigm for
+looking at disk storage works:
+
+
+In FreeBSD's new system, a device name can be broken up into up to 3
+parts.  Take a typical name like ``/dev/da0s1a'':
+
+      The first three characters represent the drive name.  If we had
+      a system with two SCSI drives on it then we'd see /dev/da0 and
+      /dev/da1 as the device entries representing the entire drives.
+
+      Next you have the "slice" (or "FDISK Partition") number,
+      as seen in the Partition Editor.  Assuming that our da0
+      contained two slices, a FreeBSD slice and a DOS slice, that
+      would give us /dev/da0s1 and /dev/da0s2 as device entries pointing
+      to the entire slices.
+
+      Next, if a slice is a FreeBSD slice, you can have a number of
+      (confusingly named) "partitions" inside of it.
+
+      These partitions are where various filesystems or swap areas live,
+      and using our hypothetical two-SCSI-disk machine again, we might
+      have something like the following layout on da0:
+
+              Name            Mountpoint
+              ----            ----------
+              da0s1a          /
+              da0s1b          <swap space>
+              da0s1e          /usr
+
+Once you understand all this, then the purpose of the label editor
+becomes fairly clear:  You're carving up the FreeBSD slices displayed
+at the top of the screen into smaller pieces, which are displayed in
+the middle of the screen, and then assigning FreeBSD file system names
+(mount points) to them.
+
+You can also use the label editor to mount existing partitions/slices
+into your filesystem hierarchy, as is frequently done for DOS FAT
+slices.  For FreeBSD partitions, you can also toggle the "newfs" state
+so that the partitions are either (re)created from scratch or simply
+checked and mounted (the contents are preserved).
+
+If you set (S)oftUpdates on a filesystem, it will cause the
+"Soft Updates" policy to be in effect for it.  This basically causes
+both metadata and data blocks to be written asynchronously to disk,
+but with extra state information which causes the metadata and any
+related data blocks to be committed in a single transaction.  This
+results in async metadata update speeds (which are considerably
+faster than the default sync) without the potential for data loss
+which could occur if you simply mounted the filesystem with purely
+"async" update policy and then had a power failure.  If you wish
+to later turn the softupdates policy back off, use the command
+"tunefs -n disable devicename".  NOTE:  It is probably not wise
+to use this on your root filesystem unless you have a large
+(e.g. non-standard size) root.  The reason is that smaller filesystems
+with significant activity can temporarily overflow if the soft updates
+policy results in free'd blocks not being "garbage collected" as fast
+as they're being requested.
+
+When you're done, type `Q' to exit.
+
+No actual changes will be made to the disk until you (C)ommit from the
+Install menu or (W)rite directly from this one.  You're working with
+what is essentially a copy of the disk label(s), both here and in the
+FDISK Partition Editor, and the actual on-disk labels won't be
+affected by any changes you make until you explicitly say so.

+This screen allows you to register yourself with the FreeBSD Project's
+user counter & statistics database.
+
+** IT IS VERY IMPORTANT THAT YOU DO THIS! **
+
+Believe me, I hate filling out forms as much as anyone, and most
+people's understandable reaction to a registration form is to say "Eh,
+what's this?  They want to send me junk mail and then on top of that
+they expect me to go to *extra* trouble in order to make it easy for
+them?!  Forget it!"
+
+This is not that kind of registration, and I strongly urge you to take
+just a few minutes to read this and find out how much the simple act
+of registering can help both you and FreeBSD.
+
+1. It is very much in your best interest, as a FreeBSD user, to stand
+   up and be counted so that various software vendors will begin to
+   take you and your operating system seriously.  There are numerous
+   ISVs (Independent Software Vendors) who would be only too happy
+   to port the kinds of applications that many FreeBSD users are
+   currently screaming for (everything from spreadsheets and word
+   processing packages to games) if they only had some idea that it
+   might be worth the trouble.  The only way to convince the ISVs that
+   FreeBSD is worth their trouble is to show them how many users
+   we have, and to do that we need your registration!  At this time
+   we literally do not know how many users FreeBSD has, and that's
+   hardly helpful when you're trying to convince someone to port
+   software to it.
+
+
+2. We will not send you *anything* you do not ask for.  Some people
+   are genuinely interested in new product announcements for FreeBSD
+   or want to hear about security issues & other important advisories
+   as they come up, and for such people we've added registration
+   options for selecting various types of additional material they
+   might be interested in receiving as a side-effect of registration.
+
+   The default behavior is to NOT put the user on any special mailing
+   lists or provide their names in mailing list data sent to
+   (carefully screened) FreeBSD product advertisers - all of that must
+   be specifically requested during the registration.
+
+Most fields in the form are fairly self-explanatory.  At the minimum,
+you should enter your first and last name as well as your email
+address so that we can weed obvious duplicates from the counter.  You
+will NOT be sent any mail at this address unless you also sign up for
+one of the additional notification services, and it's only used to
+provide us with a way of differentiating "John Smith <smith@foo.org>"
+from "John Smith <jsm@bar.com>" in the simple, no-frills registration
+case.  If you do not have an email address, some sort of postal
+address will serve the same purpose.
+
+If you also wish to receive the FreeBSD Newsletter, published and
+distributed free of charge by Walnut Creek CDROM in printed form,
+then you must specify some sort of postal address.  Likewise, if you
+elect to receive notification on the email version then you should
+specify a valid Email address.  Back-issues of the FreeBSD newsletter
+are available at ftp://ftp.freebsd.org/pub/FreeBSD/doc/newsletter/ .
+
+Should you wish to unsubscribe to the FreeBSD Newsletter or otherwise
+de-register yourself at a later time, you can simply send mail to
+register-request@freebsd.org.  If you subscribe to the announce
+mailing list (and it's a good idea) then you can modify your
+subscription at any time by sending mail to majordomo@freebsd.org
+
+
+Your cooperation with this new registration service is greatly
+appreciated, and by taking just 5 minutes to fill this out now you
+will be helping us to gather data which will greatly assist FreeBSD in
+firmly establishing a position as a serious UN*X operating system

+This is the Main Slice (``FDISK'' or PC-style Partition) Editor.
+
+Possible commands are printed at the bottom and the Master Boot Record
+contents are shown at the top.  You can move up and down with the
+arrow keys and (C)reate a new slice whenever the highlighted
+selection bar is over a slice whose type is marked as "unused."
+
+You are expected to leave this screen with at least one slice
+marked "FreeBSD."  Note that unlike Linux, you don't need to create
+multiple FreeBSD FDISK partition entries for different things like
+swap, file systems, etc.  The usual convention is to create ONE
+FreeBSD slice (FDISK partition) per drive and then subsection this slice
+into swap and file systems with the Label editor.
+
+No actual changes will be made to the disk until you (C)ommit from the
+Install menu or use the (W)rite option here!  You're working with what
+is essentially a copy of the disk label(s), both here and in the Label
+Editor.
+
+If you want to use the entire disk for FreeBSD, type `A'.  You'll be
+asked whether or not you wish to keep the disk (potentially) compatible
+with other operating systems, i.e. the information in the FDISK table
+should be kept valid.  If you select the default of `Yes', slices will be
+aligned to fictitious cylinder boundaries and space will be reserved
+in front of the FreeBSD slice for a [future] possible boot manager.
+
+For the truly dedicated disk case, you can select `No' at the
+compatibility prompt.  In that case, all BIOS geometry considerations
+will no longer be in effect and you can safely ignore any
+``The detected geometry is invalid'' warning messages you may later
+see.  It is also not necessary in this case to set a slice bootable
+or install an MBR boot manager as both things are then irrelevant.
+
+The FreeBSD slice will start at absolute sector 0 of the disk (so that
+FreeBSD's disk label is identical to the Master Boot Record) and
+extend to the very last sector of the disk medium.  Needless to say,
+such a disk cannot have any sort of a boot manager, `disk manager',
+or anything else that has to interact with the BIOS.  This option is
+therefore only considered safe for SCSI disks and most IDE disks and
+is primarily intended for people who are going to set up a dedicated
+FreeBSD server or workstation, not a typical `home PC'.
+
+The flags field has the following legend:
+
+        '='  -- This slice is properly aligned.
+        '>'  -- This slice doesn't end before cylinder 1024
+        'R'  -- This slice contains the root (/) filesystem
+        'B'  -- Slice employs BAD144 bad-spot handling
+        'C'  -- This is the FreeBSD 2.0-compatibility slice (default)
+        'A'  -- This slice is marked active.
+
+If you select a slice for Bad144 handling, it will be scanned
+for bad blocks before any new filesystems are made on it.
+
+If no slice is marked Active, you will need to either install
+a Boot Manager (the option for which will be presented later in the
+installation) or set one Active before leaving this screen.
+
+To leave the slice editor, type `Q'.
+
+Final Note: If you're absolutely sure you know what you're doing
+      and you want to use the old "Dangerously Dedicated" mode
+      which is now deprecated by sysinstall, use the (purposely)
+      undocumented `F' key.

+PLIP/SLIP users - please read through to the end of this doc!
+
+You can move through the fields with the TAB, BACK-TAB and ENTER

+Basically, the standard EMACS motion sequences.
+
+The "Extra options to ifconfig" field is kind of special (read: a

+
+If you're running SLIP or PLIP, you also need to use it for specifying
+the remote end of the link (simply type the foreign IP address in).
+In the specific case where you're running PLIP with a Linux host peer
+rather than a FreeBSD one, you also must add the "-link0" flag after the

+
+If you're dealing with an ethernet adaptor with multiple media

+HOW TO USE THIS SYSTEM
+======================
+
+[press the PageDown key to go to the next screen when you finish
+ reading this one]
+
+The following keys are recognized in most of the dialogs you'll
+encounter during this installation:
+
+KEY             ACTION
+---             ------
+SPACE           Select or toggle the current item.
+ENTER           Finish with a menu or item.
+UP ARROW        Move to previous item (or up, in a text display box).
+DOWN ARROW      Move to next item (or down, in a text display box).
+TAB             Move to next item or group.
+RIGHT ARROW     Move to next item or group (same as TAB).
+SHIFT-TAB       Move to previous item or group.
+LEFT ARROW      Move to previous item or group (same as SHIFT-TAB).
+PAGE UP         In text display boxes, scrolls up one page.
+PAGE DOWN       In text display boxes, scrolls down one page.
+F1              Display associated help text.
+
+If you see small "^(-)" or "v(+)" symbols at the edges of a menu, it
+means that there are more items above or below the current one that
+aren't being shown (due to insufficient screen space).  In text
+display boxes, the amount of text above the current point will be
+displayed as a percentage in the lower right corner.  Using the
+Up/Down arrow keys will cause the object to scroll by line.  The
+PageUp and PageDown keys will scroll by entire screens.
+
+Selecting OK in a menu will confirm whatever action it's controlling.
+Selecting Cancel will cancel the operation and generally return you to
+the previous menu. Use TAB to move the cursor around and select the
+buttons.
+
+Most screens obey the Help key (F1) - USE IT!  It generally offers useful
+context-specific hints on what to do at each stage of the installation,
+and if you're at all unsure about what to do at a given stage in the
+installation, hit F1!
+
+
+SPECIAL FEATURES:
+=================
+
+It is possible to select a menu item by typing the first character of
+its name, if unique.  This will generally be an item number.
+
+The console driver contains a scroll-back buffer for reviewing things
+that may have scrolled off the screen.  To use scroll-back, press the
+"Scroll Lock" key on your keyboard and use the arrow or Page Up/Page
+Down keys to move through the saved text.  To leave scroll-back mode,
+press the Scroll Lock key again.  This feature is most useful for
+reading back through your boot messages (go ahead, try it now!) though
+it's also useful when dealing with sub-shells or other "wizard modes"
+that don't use menus and tend to scroll their output off the top of
+the screen.
+
+FreeBSD also supports multiple "virtual consoles" which you can use to
+in order to have several active sessions at once.  Use ALT-F<n> to
+switch between screens, where `F<n>' is the function key corresponding
+to the screen you wish to see.  By default, the system comes with 8
+virtual consoles enabled - you can enable more by editing the
+/etc/ttys file and turning the "off" field to "on" in the relevant vty
+entries (up to 12).

+
+Many of the settings get reasonable defaults if you leave them blank.
+The first time you have entered the name of the new group or user, the
+system will show you what it would chose for most of these fields.
+You are free to change them, of course.
+
+
+User groups
+===========
+
+It's certainly almost generally a good idea to first create a new
+group for your users.  Common names for such a group are "users", or
+even simply "other".  Group names are used to control file access
+permissions for users that belong to the same group.  Several group
+names are already used for system files.
+
+The numerical user or group IDs are often nothing you want to care for
+explicitly.  If you don't fill in these fields, the system will chose
+reasonable defaults.  However, these numbers (rather than the
+associated names) are what the operating system actually uses to
+distinguish users and groups -- hence they should normally be unique
+to each person or group, respectively.
+
+(The initial membership list for a new group is currently
+unimplemented, sorry.)
+
+
+Users
+=====
+
+The user's login ID is a short (up to 15 characters) alphanumeric ID
+the user must enter when logging into the system.  It's often the
+initial letters of the user's name, and commonly used in lower case.
+It's also the local mail name for this user (though it's possible to
+also setup more descriptive mail alias names later).
+
+The user's login group determines which group access rights the user
+will initially get when logging in.  If an additional list of groups is
+provided where the user will become a member of, (s)he will also be
+able to access files of those groups later without providing any
+additional password etc.  Except for the "wheel" case mentioned below,
+the additional group membership list should normally not contain the
+login group again.
+
+The user's password can also be set here, and should be chosen with
+care - 6 or more characters, intermixing punctuation and numerics, and
+*not* a word from the dictionary or related to the username is a good
+password choice.
+
+Some of the system's groups have a special meaning.  In particular,
+members of group "wheel" are the only people who are later allowed to
+become superuser using the command su(1).  So if you're going to add a
+new user who should later perform administrative tasks, don't forget
+to add him to this group!  (Well, ``he'' will most likely be yourself
+in the very first place. :)
+
+Also, members of group "operator" will by default get permissions for
+minor administrative operations, like performing system backups, or
+shutting down the system -- without first becoming superuser!  So,
+take care with adding people to this group.
+
+The ``full name'' field serves as a comment only.  It is also used by
+mail front ends to determine the real name of the user, hence you
+should actually fill in the first and last name of this user.  By
+convention, this field can be divided into comma-separated subfields,
+where the office location, the work phone number, and the home phone
+number follow the full name of the user.
+
+The home directory is the directory in the filesystem where the user
+is being logged into, and where his personalized setup files (``dot
+files'', since they usually begin with a `.' and are not displayed by
+the ls(1) command by default) will be looked up.  It is often created
+under /usr/home/ or /home/.
+
+Finally, the shell is the user's initial command interpreter.  The
+default shell is /bin/sh, some users prefer the more historic
+/bin/csh.  Other, often more user-friendly and comfortable shells can
+be found in the ports and packages collection.

+.Sh NAME
+.Nm sysinstall
+.Nd system installation and configuration tool
+.Sh SYNOPSIS
+.Nm
+.Op Ar var=value
+.Op Ar function
+.Op Ar ...
+.Sh DESCRIPTION
+.Nm
+is a utility for installing and configuring
+.Fx
+systems.
+It is the first utility invoked by the
+.Fx
+installation boot
+floppy and is also copied into
+.Pa /stand/sysinstall
+on newly installed
+.Fx
+systems for use in later configuring the system.
+.Pp
+The
+.Nm
+program is generally invoked without arguments for the default
+behavior, where the main installation/configuration menu is presented.
+.Pp
+On those occasions where it is deemed necessary to invoke a subsystem
+of sysinstall directly, however, it is also possible to do so by
+naming the appropriate function entry points on the command line.
+Since this action is essentially identical to running an installation
+script, each command-line argument corresponding to a line of script,
+the reader is encouraged to read the section on scripting for more
+information on this feature.
+.Sh NOTES
+.Nm
+is essentially nothing more than a monolithic C program with
+the ability to write MBRs and disk labels (through the services
+of the
+.Xr libdisk 3
+library) and install distributions or packages onto new and
+existing
+.Fx
+systems.  It also contains some extra intelligence
+for running as a replacement for
+.Xr init 8
+when it's invoked by the
+.Fx
+installation boot procedure.  It
+assumes very little in the way of additional utility support and
+performs most file system operations by calling the relevant syscalls
+(such as
+.Xr mount 2 )
+directly.
+.Pp
+.Nm
+currently uses the
+.Xr dialog 3
+library to do user interaction with simple ANSI line graphics, color
+support for which is enabled by either running on a syscons VTY or some
+other color-capable terminal emulator (newer versions of xterm will support
+color when using the
+.Dq xterm-color
+termcap entry).
+.Pp
+This product is currently at the end of its life cycle and will
+eventually be replaced.
+.Sh RUNNING SCRIPTS
+.Nm
+may be either driven interactively through its various internal menus
+or run in batch mode, driven by an external script.  Such a script may
+be loaded and executed in one of 3 ways:
+.Bl -tag -width Ds
+.It Sy "LOAD_CONFIG_FILE"
+If
+.Nm
+is compiled with LOAD_CONFIG_FILE set in the environment
+(or in the Makefile) to some value, then that value will
+be used as the filename to automatically look for and load
+when
+.Nm
+starts up and with no user interaction required.
+This option is aimed primarily at large sites who wish to create a
+single prototype install for multiple machines with largely identical
+configurations and/or installation options.
+.It Sy "MAIN MENU"
+If
+.Nm
+is run interactively, that is to say in the default manner, it will
+bring up a main menu which contains a "load config file" option.
+Selecting this option will prompt for the name of a script file which
+it then will attempt to load from a DOS or UFS formatted floppy.
+.It Sy "COMMAND LINE"
+Each command line argument is treated as a script directive
+when
+.Nm
+is run in multi-user mode.  Execution ends either by explicit request
+(e.g. calling the
+.Ar shutdown
+directive), upon reaching the end of the argument list or on error.
+.Pp
+For example:
+.Bd -literal
+/stand/sysinstall _ftpPath=ftp://ziggy/pub/ mediaSetFTP configPackages
+.Ed
+.Pp
+Would initialize
+.Nm
+for FTP installation media (using the server `ziggy') and then
+bring up the package installation editor, exiting when finished.
+.El
+.Sh SCRIPT SYNTAX
+A script is a list of one or more directives, each directive taking
+the form of:
+.Pp
+.Ar var=value
+.Pp
+.Ar function
+.Pp
+or
+.Ar #somecomment
+.Pp
+Where
+.Ar var=value
+is the assignment of some internal
+.Nm
+variable, e.g. "ftpPass=FuNkYChiKn", and
+.Ar function
+is the name of an internal
+.Nm
+function, e.g. "mediaSetFTP", and
+.Ar #comment
+is a single-line comment for documentation purposes (ignored by
+sysinstall).  Each directive must be by itself on a single line,
+functions taking their arguments by examining known variable names.
+This requires that you be sure to assign the relevant variables before
+calling a function which requires them.
+.Pp
+The
+.Ar noError
+variable can be assigned before each directive: this will cause any error
+detected while processing the directive itself to be ignored.
+The value of
+.Ar noError
+will automatically reset to the default "unassigned" every time a directive is
+processed.
+.Pp
+When and where a function depends on the settings of one or more variables
+will be noted in the following table:
+.Pp
+.Sy "Function Glossary" :
+.Pp
+.Bl -tag -width indent
+.It configAnonFTP
+Invoke the Anonymous FTP configuration menu.
+.Pp
+.Sy Variables :
+None
+.It configRouter
+Select which routing daemon you wish to use, potentially
+loading any required 3rd-party routing daemons as necessary.
+.Pp
+.Sy Variables :
+.Bl -tag -width indent
+.It router
+can be set to the name of the desired routing daemon,
+e.g.\&
+.Dq routed
+or
+.Dq gated ,
+otherwise it is prompted for.
+.El
+.It configNFSServer
+Configure host as an NFS server.
+.Pp
+.Sy Variables :
+None
+.It configNTP
+Configure host as a user of the Network Time Protocol.
+.Pp
+.Sy Variables :
+.Bl -tag -width indent
+.It ntpdate_flags
+The flags to
+.Xr ntpdate 8 ,
+that is to say the name of the server to sync from.
+.El
+.It configPCNFSD
+Configure host to support PC NFS.
+.Pp
+.Sy Variables :
+.Bl -tag -width indent
+.It pcnfsd_pkg
+The name of the PCNFSD package to load if necessary (defaults to hard coded
+version).
+.El
+.It configPackages
+Bring up the interactive package management menu.
+.Pp
+.Sy Variables :
+None
+.It configUsers
+Add users and/or groups to the system.
+.Pp
+.Sy Variables :
+None
+.It configXEnvironment
+Configure the X display subsystem.
+.Pp
+.Sy Variables :
+None
+.It diskPartitionEditor
+Invokes the disk partition (MBR) editor.
+.Pp
+.Sy Variables :
+.Bl -tag -width findx
+.It geometry
+The disk geometry, as a cyls/heads/sectors formatted string.  Default: no
+change to geometry.
+.It partition
+Set to disk partitioning type or size, its value being
+.Ar free
+in order to use only remaining free space for
+.Fx ,
+.Ar all
+to use the entire disk for
+.Fx
+but maintain a proper partition
+table,
+.Ar existing
+to use an existing
+.Fx
+partition (first found),
+.Ar exclusive
+to use the disk in
+.Dq dangerously dedicated
+mode or, finally,
+.Ar somenumber
+to allocate
+.Ar somenumber
+blocks of available free space to a new
+.Fx
+partition.
+Default:  Interactive mode.
+.It bootManager
+is set to one of
+.Ar boot
+to signify the installation of a boot manager,
+.Ar standard
+to signify installation of a "standard" non-boot MGR DOS
+MBR or
+.Ar none
+to indicate that no change to the boot manager is desired.
+Default: none.
+.It diskInteractive
+If set, bring up the interactive disk partition editor.
+.El
+.Pp
+Note: Nothing is actually written to disk by this function, a explicit call to
+.Ar diskPartitionWrite
+being required for that to happen.
+.It diskPartitionWrite
+Causes any pending MBR changes (typically from the
+.Ar diskPartitionEditor
+function) to be written out.
+.Pp
+.Sy Variables :
+None
+.It diskLabelEditor
+Invokes the disk label editor.  This is a bit trickier from a script
+since you need to essentially label everything inside each
+.Fx
+(type 0xA5) partition created by the
+.Ar diskPartitionEditor
+function, and that requires knowing a few rules about how things are
+laid out.  When creating a script to automatically allocate disk space
+and partition it up, it is suggested that you first perform the
+installation interactively at least once and take careful notes as to
+what the slice names will be, then and only then hardwiring them into
+the script.
+.Pp
+For example, let's say you have a SCSI disk on which you've created a new
+.Fx
+partition in slice 2 (your DOS partition residing in slice 1).
+The slice name would be
+.Ar da0s2
+for the whole
+.Fx
+partition
+.Ar ( da0s1
+being your DOS primary
+partition).  Now let's further assume that you have 500MB in this
+partition and you want to sub-partition that space into root, swap,
+var and usr file systems for
+.Fx .
+Your invocation of the
+.Ar diskLabelEditor
+function might involve setting the following variables:
+.Bl -tag -width findx
+.It Li "da0s2-1=ufs 40960 /"
+A 20MB root file system (all sizes are in 512 byte blocks).
+.It Li "da0s2-2=swap 131072 /"
+A 64MB swap partition.
+.It Li "da0s2-3=ufs 204800 /var"
+A 100MB /var file system.
+.It Li "da0s2-4=ufs 0 /usr 1"
+With the balance of free space (around 316MB) going to the /usr
+file system and with soft-updates enabled (the argument following
+the mount point, if non-zero, means to set the soft updates flag).
+.El
+.Pp
+One can also use the
+.Ar diskLabelEditor
+for mounting or erasing existing partitions as well as creating new
+ones.  Using the previous example again, let's say that we also wanted
+to mount our DOS partition and make sure that an
+.Pa /etc/fstab
+entry is created for it in the new installation.  Before calling the
+.Ar diskLabelEditor
+function, we simply add an additional line:
+.Pp
+.Dl "da0s1=/dos_c N"
+.Pp
+before the call.  This tells the label editor that you want to mount
+the first slice on
+.Pa /dos_c
+and not to attempt to newfs it (not that
+.Nm
+would attempt this for a DOS partition in any case, but it could just
+as easily be an existing UFS partition being named here and the 2nd
+field is non-optional).
+.Pp
+You can also set the
+.Ar diskInteractive
+variable to request that the disk label editor use an interactive dialog
+to partition the disk instead of using variables to explicitly layout the
+disk as described above.
+.Pp
+Note:  No file system data is actually written to disk until an
+explicit call to
+.Ar diskLabelCommit
+is made.
+.It diskLabelCommit
+Writes out all pending disklabel information and creates and/or mounts any
+file systems which have requests pending from the
+.Ar diskLabelEditor
+function.
+.Pp
+.Sy Variables :
+None
+.It distReset
+Resets all selected distributions to the empty set (no distributions selected).
+.Pp
+.Sy Variables :
+None
+.It distSetCustom
+Allows the selection of a custom distribution set (e.g. not just on of the
+existing "canned" sets) with no user interaction.
+.Pp

+.Sh DISTRIBUTION MEDIA
+The following files can be used to affect the operation of
+.Nm
+when used during initial system installation.
+.Bl -tag -width ".Pa packages/INDEX"
+.It Pa cdrom.inf
+A text file of properties, listed one per line, that describe the
+contents of the media in use.
+The syntax for each line is simply
+.Dq Ar property No = Ar value .
+Currently, only the following properties are recognized.
+.Bl -tag -width ".Va CD_MACHINE_ARCH"
+.It Va CD_VERSION
+This property should be set to the
+.Fx
+version on the current
+media volume.
+For example,
+.Dq Li "CD_VERSION = 4.6" .
+.It Va CD_MACHINE_ARCH
+This property should be set to the architecture of the contents on
+this volume.
+This property is normally only used with
+.Fx
+products that contain
+CDs for different architectures, to provide better error messages if
+users try to install Alpha packages on an i386 machine.
+For example,
+.Dq Li "CD_MACHINE_ARCH = alpha" .
+.It Va VOLUME
+In a multi-volume collection (such as the
+.Fx
+4-CD set), the
+.Pa ports/INDEX
+file on each disc should contain the full package index for the set.
+The last field of the
+.Pa INDEX
+file denotes which volume the package
+appears on, and the
+.Va VOLUME
+property here defines the volume ID of the current disc.
+.El
+.It Pa packages/INDEX
+The package index file.
+Each package is listed on a separate line with additional meta-data
+such as the required dependencies.
+This index is generated by
+.Dq Li "make index"
+from the
+.Xr ports 7
+collection.
+When multi-volume support is enabled, an additional field should be
+added to each line indicating which media volume contains the given
+package.
+.El
+.Pp
+For information about building a full release of
+.Fx ,
+please see
+.Xr release 7 .
+.Sh FILES
+This utility may edit the contents of
+.Pa /etc/rc.conf ,
+.Pa /etc/hosts ,
+and
+.Pa /etc/resolv.conf
+as necessary to reflect changes in the network configuration.
+.Sh SEE ALSO
+If you have a reasonably complete source tree online, take
+a look at
+.Pa /usr/src/usr.sbin/sysinstall/install.cfg
+for a sample installation script.
+.Sh BUGS
+This utility is a prototype which lasted several years past
+its expiration date and is greatly in need of death.

+.Dd June 9, 1993
+.Dt SYSLOG.CONF 5
+.Os
+.Sh NAME
+.Nm syslog.conf
+.Nd
+.Xr syslogd 8
+configuration file
+.Sh DESCRIPTION
+The
+.Nm
+file is the configuration file for the
+.Xr syslogd 8
+program.
+It consists of
+blocks of lines separated by
+.Em program
+and
+.Em hostname
+specifications,
+with each line containing two fields: the
+.Em selector
+field which specifies the types of messages and priorities to which the
+line applies, and an
+.Em action
+field which specifies the action to be taken if a message
+.Xr syslogd 8
+receives matches the selection criteria.
+The
+.Em selector
+field is separated from the
+.Em action
+field by one or more tab characters or spaces.
+.Pp
+Note that if you use spaces as separators, your
+.Nm
+might be incompatible with other Unices or Unix-like systems.
+This functionality was added for the ease of configuration
+(e.g. it is possible to cut-and-paste into
+.Nm ) ,
+and to avoid possible mistakes.
+This change however preserves
+backwards compatibility with the old style of the
+.Nm
+(i.e. tab characters only).
+.Pp
+The
+.Em selectors
+are encoded as a
+.Em facility ,
+a period
+.Pq Dq \&. ,
+an optional set of comparison flags
+.Pq Bq <=> ,
+and a
+.Em level ,
+with no intervening white-space.
+Both the
+.Em facility
+and the
+.Em level
+are case insensitive.
+.Pp
+The
+.Em facility
+describes the part of the system generating the message, and is one of
+the following keywords: auth, authpriv, console, cron, daemon, ftp, kern,
+lpr, mail, mark, news, ntp, security, syslog, user, uucp and local0 through
+local7.
+These keywords (with the exception of mark) correspond to the
+similar
+.Dq Dv LOG_
+values specified to the
+.Xr openlog 3
+and
+.Xr syslog 3
+library routines.
+.Pp
+The
+.Em comparison flags
+may be used to specify exactly what is logged.
+The default set of comparison flags are
+.Dq =>
+(or, if you prefer,
+.Dq >= ) ,
+which means that messages from the specified
+.Em facility
+list of a priority
+level equal or greater than
+.Em level
+will be logged.
+.Pp
+The
+.Em level
+describes the severity of the message, and is a keyword from the
+following ordered list (higher to lower): emerg, alert, crit, err,
+warning, notice, info and debug.
+These keywords correspond to the
+similar
+.Dq Dv LOG_
+values specified to the
+.Xr syslog 3
+library routine.
+.Pp
+Each block of lines is separated from the previous block by a
+.Em program
+or
+.Em hostname
+specification.
+A block will only log messages corresponding to the most recent
+.Em program
+and
+.Em hostname
+specifications given.
+Thus, a block which selects
+.Ql ppp
+as the
+.Em program ,
+directly followed by a block that selects messages from the
+.Em hostname
+.Ql dialhost ,
+then the second block will only log messages
+from the
+.Xr ppp 8
+program on dialhost.
+.Pp
+A
+.Em program
+specification is a line beginning with
+.Ql #!prog
+or
+.Ql !prog
+(the former is for compatibility with the previous syslogd, if one is sharing
+.Nm
+files, for example)
+and the following blocks will be associated with calls to
+.Xr syslog 3
+from that specific program.
+A
+.Em program
+specification for
+.Ql foo
+will also match any message logged by the kernel with the prefix
+.Ql "foo: " .
+A
+.Em hostname
+specification of the form
+.Ql #+hostname
+or
+.Ql +hostname
+and the following blocks will be applied to messages
+received from the specified hostname.
+Alternatively, a
+.Em hostname
+specification
+.Ql #-hostname
+or
+.Ql -hostname
+causes the following blocks to be applied to messages
+from any host but the one specified.
+If the hostname is given as
+.Ql @ ,
+the local hostname will be used.
+A
+.Em program
+or
+.Em hostname
+specification may be reset by giving the program or hostname as
+.Ql * .
+.Pp
+See
+.Xr syslog 3
+for a further descriptions of both the
+.Em facility
+and
+.Em level
+keywords and their significance.
+It's preferred that selections be made on
+.Em facility
+rather than
+.Em program ,
+since the latter can easily vary in a networked environment.
+In some cases,
+though, an appropriate
+.Em facility
+simply doesn't exist.
+.Pp
+If a received message matches the specified
+.Em facility
+and is of the specified
+.Em level
+.Em (or a higher level) ,
+and the first word in the message after the date matches the
+.Em program ,
+the action specified in the
+.Em action
+field will be taken.
+.Pp
+Multiple
+.Em selectors
+may be specified for a single
+.Em action
+by separating them with semicolon
+.Pq Dq \&;
+characters.
+It is important to note, however, that each
+.Em selector
+can modify the ones preceding it.
+.Pp
+Multiple
+.Em facilities
+may be specified for a single
+.Em level
+by separating them with comma
+.Pq Dq \&,
+characters.
+.Pp
+An asterisk
+.Pq Dq *
+can be used to specify all
+.Em facilities
+all
+.Em levels
+or all
+.Em programs .
+.Pp
+The special
+.Em facility
+.Dq mark
+receives a message at priority
+.Dq info
+every 20 minutes
+(see
+.Xr syslogd 8 ) .
+This is not enabled by a
+.Em facility
+field containing an asterisk.
+.Pp
+The special
+.Em level
+.Dq none
+disables a particular
+.Em facility .
+.Pp
+The
+.Em action
+field of each line specifies the action to be taken when the
+.Em selector
+field selects a message.
+There are five forms:
+.Bl -bullet
+.It
+A pathname (beginning with a leading slash).
+Selected messages are appended to the file.
+.It
+A hostname (preceded by an at
+.Pq Dq @
+sign).
+Selected messages are forwarded to the
+.Xr syslogd 8
+program on the named host.
+.It
+A comma separated list of users.
+Selected messages are written to those users
+if they are logged in.
+.It
+An asterisk.
+Selected messages are written to all logged-in users.
+.It
+A vertical bar
+.Pq Dq \&| ,
+followed by a command to pipe the selected
+messages to.  The command is passed to
+.Xr sh 1
+for evaluation, so usual shell metacharacters or input/output
+redirection can occur.  (Note however that redirecting
+.Xr stdio 3
+buffered output from the invoked command can cause additional delays,
+or even lost output data in case a logging subprocess exited with a
+signal.)  The command itself runs with
+.Em stdout
+and
+.Em stderr
+redirected to
+.Pa /dev/null .
+Upon receipt of a
+.Dv SIGHUP ,
+.Xr syslogd 8
+will close the pipe to the process.  If the process didn't exit
+voluntarily, it will be sent a
+.Dv SIGTERM
+signal after a grace period of up to 60 seconds.
+.Pp
+The command will only be started once data arrives that should be piped
+to it.  If it exited later, it will be restarted as necessary.  So if it
+is desired that the subprocess should get exactly one line of input only
+(which can be very resource-consuming if there are a lot of messages
+flowing quickly), this can be achieved by exiting after just one line of
+input.  If necessary, a script wrapper can be written to this effect.
+.Pp
+Unless the command is a full pipeline, it's probably useful to
+start the command with
+.Em exec
+so that the invoking shell process does not wait for the command to
+complete.  Warning: the process is started under the UID invoking
+.Xr syslogd 8 ,
+normally the superuser.
+.El
+.Pp
+Blank lines and lines whose first non-blank character is a hash
+.Pq Dq #
+character are ignored.

+.Sh IMPLEMENTATION NOTES
+The
+.Dq kern
+facility is usually reserved for messages
+generated by the local kernel.
+Other messages logged with facility

+The effects of multiple
+.Em selectors
+are sometimes not intuitive.
+For example
+.Dq mail.crit,*.err
+will select
+.Dq mail
+facility messages at the level of
+.Dq err
+or higher, not at the level of
+.Dq crit
+or higher.
+.Pp
+In networked environments, note that not all operating systems
+implement the same set of facilities.  The facilities
+authpriv, cron, ftp, and ntp that are known to this implementation
+might be absent on the target system.  Even worse, DEC UNIX uses
+facility number 10 (which is authpriv in this implementation) to
+log events for their AdvFS filesystem.

+.Nm syslogd
+.Nd log systems messages
+.Sh SYNOPSIS
+.Nm
+.Op Fl 46Adknosuv
+.Op Fl a Ar allowed_peer
+.Op Fl b Ar bind_address
+.Op Fl f Ar config_file
+.Op Fl m Ar mark_interval
+.Op Fl p Ar log_socket
+.Op Fl P Ar pid_file
+.Op Fl l Ar path
+.Sh DESCRIPTION
+The
+.Nm
+daemon reads and logs messages to the system console, log files, other
+machines and/or users as specified by its configuration file.
+.Pp
+The options are as follows:
+.Bl -tag -width indent
+.It Fl 4
+Forces
+.Nm
+to use IPv4 addresses only.
+.It Fl 6
+Forces
+.Nm
+to use IPv6 addresses only.
+.It Fl A
+Ordinarily,
+.Nm
+tries to send the message to only one address
+even if the host has more than one A or AAAA record.
+If this option is specified,
+.Nm
+tries to send the message to all addresses.
+.It Fl a Ar allowed_peer
+Allow
+.Ar allowed_peer
+to log to this
+.Nm
+using UDP datagrams.  Multiple
+.Fl a
+options may be specified.
+.Pp
+.Ar Allowed_peer
+can be any of the following:
+.Bl -tag -width "ipaddr/masklen[:service]XX"
+.It Xo
+.Sm off
+.Ar ipaddr
+.No / Ar masklen
+.Op : Ar service
+.Sm on
+.Xc
+Accept datagrams from
+.Ar ipaddr
+(in the usual dotted quad notation) with
+.Ar masklen
+bits being taken into account when doing the address comparison.
+.Ar ipaddr
+can be also IPv6 address by enclosing the address with
+.Ql \&[
+and
+.Ql \&] .
+If specified,
+.Ar service
+is the name or number of an UDP service (see
+.Xr services 5 )
+the source packet must belong to.  A
+.Ar service
+of
+.Ql \&*
+allows packets being sent from any UDP port.  The default
+.Ar service
+is
+.Ql syslog .
+If
+.Ar ipaddr
+is IPv4 address, a missing
+.Ar masklen
+will be substituted by the historic class A or class B netmasks if
+.Ar ipaddr
+belongs into the address range of class A or B, respectively, or
+by 24 otherwise.  If
+.Ar ipaddr
+is IPv6 address, a missing
+.Ar masklen
+will be substituted by 128.
+.It Xo
+.Sm off
+.Ar domainname Op : Ar service
+.Sm on
+.Xc
+Accept datagrams where the reverse address lookup yields
+.Ar domainname
+for the sender address.  The meaning of
+.Ar service
+is as explained above.
+.It Xo
+.Sm off
+.No * Ar domainname Op : Ar service
+.Sm on
+.Xc
+Same as before, except that any source host whose name
+.Em ends
+in
+.Ar domainname
+will get permission.
+.El
+.Pp
+The
+.Fl a
+options are ignored if the
+.Fl s
+option is also specified.
+.It Fl b Ar bind_address
+Specify one specific IP address or hostname to bind to.
+If a hostname is specified,
+the IPv4 or IPv6 address which corresponds to it is used.
+.It Fl c
+Disable the compression of repeated instances of the same line
+into a single line of the form
+.Dq Li "last message repeated N times"
+when the output is a pipe to another program.
+If specified twice, disable this compression in all cases.
+.It Fl d
+Put
+.Nm
+into debugging mode.  This is probably only of use to developers working on
+.Nm .
+.It Fl f
+Specify the pathname of an alternate configuration file;
+the default is
+.Pa /etc/syslog.conf .
+.It Fl k
+Disable the translation of
+messages received with facility
+.Dq kern
+to facility
+.Dq user .
+Usually the
+.Dq kern
+facility is reserved for messages read directly from
+.Pa /dev/klog .
+.It Fl m
+Select the number of minutes between
+.Dq mark
+messages; the default is 20 minutes.
+.It Fl n
+Disable dns query for every request.
+.It Fl o
+Prefix kernel messages with the full kernel boot file as determined by
+.Xr getbootfile 3 .
+Without this, the kernel message prefix is always
+.Dq Li kernel: .
+.It Fl p
+Specify the pathname of an alternate log socket to be used instead;
+the default is
+.Pa /var/run/log .
+.It Fl P
+Specify an alternative file in which to store the process ID.
+The default is
+.Pa /var/run/syslog.pid .
+.It Fl l
+Specify a location where
+.Nm
+should place an additional log socket.
+Up to 19 additional logging sockets can be specified.
+The primary use for this is to place additional log sockets in
+.Pa /var/run/log
+of various chroot filespaces.
+.It Fl s
+Operate in secure mode.  Do not log messages from remote machines.  If
+specified twice, no network socket will be opened at all, which also
+disables logging to remote machines.
+.It Fl u
+Unique priority logging.  Only log messages at the specified priority.
+Without this option, messages at the stated priority or higher are logged.
+This option changes the default comparison from
+.Dq =>
+to
+.Dq = .
+.It Fl v
+Verbose logging.  If specified once, the numeric facility and priority are
+logged with each locally-written message.  If specified more than once,
+the names of the facility and priority are logged with each locally-written
+message.
+.El
+.Pp
+The
+.Nm
+daemon reads its configuration file when it starts up and whenever it
+receives a hangup signal.
+For information on the format of the configuration file,
+see
+.Xr syslog.conf 5 .
+.Pp
+The
+.Nm
+daemon reads messages from the
+.Tn UNIX
+domain socket
+.Pa /var/run/log ,
+from an Internet domain socket specified in
+.Pa /etc/services ,
+and from the special device
+.Pa /dev/klog
+(to read kernel messages).
+.Pp
+The
+.Nm
+daemon creates its process ID file,
+by default
+.Pa /var/run/syslog.pid ,
+and stores its process
+ID there.
+This can be used to kill or reconfigure
+.Nm .
+.Pp
+The message sent to
+.Nm
+should consist of a single line.
+The message can contain a priority code, which should be a preceding
+decimal number in angle braces, for example,
+.Sq Aq 5 .
+This priority code should map into the priorities defined in the
+include file
+.Aq Pa sys/syslog.h .
+.Pp
+For security reasons,
+.Nm
+will not append to log files that do not exist;
+therefore, they must be created manually before running
+.Nm .

+.Sh HISTORY
+The
+.Nm
+command appeared in
+.Bx 4.3 .
+.Pp
+The
+.Fl a ,
+.Fl s ,
+.Fl u ,
+and
+.Fl v
+options are
+.Fx 2.2
+extensions.
+.Sh BUGS
+The ability to log messages received in UDP packets is equivalent to
+an unauthenticated remote disk-filling service, and should probably be
+disabled by default.  Some sort of
+.No inter- Ns Nm syslogd
+authentication mechanism ought to be worked out.  To prevent the worst
+abuse, use of the
+.Fl a
+option is therefore highly recommended.
+.Pp
+The
+.Fl a
+matching algorithm doesn't pretend to be very efficient; use of numeric
+IP addresses is faster than domain name comparison.  Since the allowed
+peer list is being walked linearly, peer groups where frequent messages
+are being anticipated from should be put early into the
+.Fl a
+list.
+.Pp
+The log socket was moved from
+.Pa /dev
+to ease the use of a read-only root filesystem.
+This may confuse
+some old binaries so that a symbolic link might be used for a
+transitional period.

+.Sh NAME
+.Nm tcpslice
+.Nd extract pieces of and/or glue together tcpdump files
+.Sh SYNOPSIS
+.Nm
+.Op Fl dRrt
+.Op Fl w Ar file
+.Op Ar start-time Op end-time
+.Ar
+.Sh DESCRIPTION
+The
+.Nm
+utility extracts portions of packet-trace files generated using
+.Xr tcpdump 1 Ns 's
+.Fl w
+flag.
+It can also be used to glue together several such files, as discussed
+below.
+.Pp
+The basic operation of
+.Nm
+is to copy to
+.Pa stdout
+all packets from its input file(s) whose timestamps fall
+within a given range.  The starting and ending times of the range
+may be specified on the command line.  All ranges are inclusive.
+The starting time defaults
+to the time of the first packet in the first input file; we call
+this the
+.Em first time .
+The ending time defaults to ten years after the starting time.
+Thus, the command
+.Nm
+.Ar trace-file
+simply copies
+.Ar trace-file
+to
+.Pa stdout
+(assuming the file does not include more than
+ten years' worth of data).
+.Pp
+There are a number of ways to specify times.  The first is using
+Unix timestamps of the form
+.Em sssssssss.uuuuuu
+(this is the format specified by
+.Xr tcpdump 1 Ns 's
+.Fl tt
+flag).
+For example,
+.Em 654321098.7654
+specifies 38 seconds and 765,400 microseconds
+after 8:51PM PDT, Sept. 25, 1990.
+.Pp
+All examples in this manual are given
+for PDT times, but when displaying times and interpreting times symbolically
+as discussed below,
+.Nm
+uses the local timezone, regardless of the timezone in which the
+.Xr tcpdump 1
+file was generated.  The daylight-savings setting used is that which is
+appropriate for the local timezone at the date in question.  For example,
+times associated with summer months will usually include daylight-savings
+effects, and those with winter months will not.
+.Pp
+Times may also be specified relative
+to either the
+.Em first time
+(when specifying a starting time)
+or the starting time (when specifying an ending time)
+by preceding a numeric value in seconds with a `+'.
+For example, a starting time of
+.Em +200
+indicates 200 seconds after the
+.Em first time ,
+and the two arguments
+.Em +200 +300
+indicate from 200 seconds after the
+.Em first time
+through 500 seconds after the
+.Em first time .
+.Pp
+Times may also be specified in terms of years (y), months (m), days (d),
+hours (h), minutes (m), seconds (s), and microseconds(u).  For example,
+the Unix timestamp 654321098.7654 discussed above could also be expressed
+as
+.Em 90y9m25d20h51m38s765400u .
+.Pp
+When specifying times using this style, fields that are omitted default
+as follows.  If the omitted field is a unit
+.Em greater
+than that of the first specified field, then its value defaults to
+the corresponding value taken from either
+.Em first time
+(if the starting time is being specified) or the starting time
+(if the ending time is being specified).
+If the omitted field is a unit
+.Em less
+than that of the first specified field, then it defaults to zero.
+For example, suppose that the input file has a
+.Em first time
+of the Unix timestamp mentioned above, i.e., 38 seconds and 765,400 microseconds
+after 8:51PM PDT, Sept. 25, 1990.  To specify 9:36PM PDT (exactly) on the
+same date we could use
+.Em 21h36m .
+To specify a range from 9:36PM PDT through 1:54AM PDT the next day we
+could use
+.Em 21h36m 26d1h54m .
+.Pp
+Relative times can also be specified when using the
+.Em ymdhmsu
+format.  Omitted fields then default to 0 if the unit of the field is
+.Em greater
+than that of the first specified field, and to the corresponding value
+taken from either the
+.Em first time
+or the starting time if the omitted field's unit is
+.Em less
+than that of the first specified field.  Given a
+.Em first time
+of the Unix timestamp mentioned above,
+.Em 22h +1h10m
+specifies a range from 10:00PM PDT on that date through 11:10PM PDT, and
+.Em +1h +1h10m
+specifies a range from 38.7654 seconds after 9:51PM PDT through 38.7654
+seconds after 11:01PM PDT.  The first hour of the file could be extracted
+using
+.Em +0 +1h .
+.Pp
+Note that with the
+.Em ymdhmsu
+format there is an ambiguity between using
+.Em m
+for `month' or for `minute'.  The ambiguity is resolved as follows: if an
+.Em m
+field is followed by a
+.Em d
+field then it is interpreted as specifying months; otherwise it
+specifies minutes.
+.Pp
+If more than one input file is specified then
+.Nm
+first copies packets lying in the given range from the first file; it
+then increases the starting time of the range to lie just beyond the
+timestamp of the last packet in the first file, repeats the process
+with the second file, and so on.  Thus files with interleaved packets
+are
+.Em not
+merged.  For a given file, only packets that are newer than any in the
+preceding files will be considered.  This mechanism avoids any possibility
+of a packet occurring more than once in the output.
+.Sh OPTIONS
+If any of
+.Fl R ,
+.Fl r
+or
+.Fl t
+are specified then
+.Nm
+reports the timestamps of the first and last packets in each input file
+and exits.  Only one of these three options may be specified.
+.Pp
+The following options are available:
+.Bl -tag -width indent
+.It Fl d
+Dump the start and end times specified by the given range and
+exit.  This option is useful for checking that the given range actually
+specifies the times you think it does.  If one of
+.Fl R ,
+.Fl r
+or
+.Fl t
+has been specified then the times are dumped in the corresponding
+format; otherwise, raw format
+.Pq Fl R
+is used.
+.It Fl R
+Dump the timestamps of the first and last packets in each input file
+as raw timestamps (i.e., in the form
+.Em sssssssss.uuuuuu ) .
+.It Fl r
+Same as
+.Fl R
+except the timestamps are dumped in human-readable format, similar
+to that used by
+.Xr date 1 .
+.It Fl t
+Same as
+.Fl R
+except the timestamps are dumped in
+.Nm
+format, i.e., in the
+.Em ymdhmsu
+format discussed above.
+.It Fl w Ar file
+Direct the output to
+.Ar file
+rather than
+.Pa stdout .

+.An Vern Paxson Aq vern@ee.lbl.gov ,
+of Lawrence Berkeley Laboratory, University of California, Berkeley, CA.
+.Sh BUGS
+An input filename that beings with a digit or a `+' can be confused
+with a start/end time.  Such filenames can be specified with a
+leading `./'; for example, specify the file `04Jul76.trace' as
+`./04Jul76.trace'.
+.Pp
+The
+.Nm
+utility cannot read its input from
+.Pa stdin ,
+since it uses random-access
+to rummage through its input files.
+.Pp
+The
+.Nm
+utility refuses to write to its output if it is a terminal
+(as indicated by
+.Xr isatty 3 ) .
+This is not a bug but a feature,
+to prevent it from spraying binary data to the user's terminal.
+Note that this means you must either redirect
+.Pa stdout
+or specify an
+output file via
+.Fl w .
+.Pp
+The
+.Nm
+utility will not work properly on
+.Xr tcpdump 1
+files spanning more than one year;
+with files containing portions of packets whose original length was
+more than 65,535 bytes; nor with files containing fewer than three packets.
+Such files result in
+the error message: `couldn't find final packet in file'.  These problems
+are due to the interpolation scheme used by
+.Nm
+to greatly speed up its processing when dealing with large trace files.
+Note that
+.Nm
+can efficiently extract slices from the middle of trace files of any
+size, and can also work with truncated trace files (i.e., the final packet
+in the file is only partially present, typically due to
+.Xr tcpdump 1
+being ungracefully killed).

+Introduction
+.PP
+The Time Synchronization Protocol (TSP) 
+has been designed for specific use by the program \fItimed\fP,
+a local area network clock synchronizer for 
+the UNIX 4.3BSD operating
+system.
+Timed is built on the DARPA UDP protocol [4] and
+is based on a master slave scheme.
+.PP
+TSP serves a dual purpose.
+First, it supports messages for the synchronization of the clocks 
+of the various hosts in a local area network.
+Second, it supports messages for the election that occurs
+among slave time daemons when, for any reason, the master disappears.
+The synchronization mechanism and the election procedure 
+employed by the program timed are described 
+in other documents [1,2,3].
+.PP
+Briefly, the synchronization software, which works in a 
+local area network, consists of a collection of \fItime daemons\fP
+(one per machine) and is based on a master-slave
+structure.
+The present implementation keeps processor clocks synchronized 
+within 20 milliseconds.
+A \fImaster time daemon\fP measures the time
+difference between the clock of the machine on which it 
+is running and those of all other machines.  The current implementation
+uses ICMP \fITime Stamp Requests\fP [5] to measure the clock difference
+between machines.
+The master computes the \fInetwork time\fP as the average of the 
+times provided by nonfaulty clocks.\**
+.FS
+A clock is considered to be faulty when its value 
+is more than a small specified
+interval apart from the majority of the clocks 
+of the machines on the same network.
+See [1,2] for more details.
+.FE
+It then sends to each \fIslave time daemon\fP the
+correction that should be performed on the clock of its machine.
+This process is repeated periodically.
+Since the correction is expressed as a time difference rather than an 
+absolute time, transmission delays do not interfere with synchronization.
+When a machine comes up and joins the network,
+it starts a slave time daemon, which
+will ask the master for the correct time and will reset the machine's clock
+before any user activity can begin.
+The time daemons therefore maintain a single network time in spite of 
+the drift of clocks away from each other. 
+.PP
+Additionally, a time daemon on gateway machines may run as 
+a \fIsubmaster\fP.
+A submaster time daemon functions as a slave on one network that
+already has a master and as master on other networks.
+In addition, a submaster is responsible for propagating broadcast
+packets from one network to the other.
+.PP
+To ensure that service provided is continuous and reliable,
+it is necessary to implement an election algorithm that will elect a
+new master should the machine running the current master crash, the master
+terminate (for example, because of a run-time error), or the network be
+partitioned.
+Under our algorithm, slaves are able to realize when the master has
+stopped functioning and to elect a new master from among themselves.
+It is important to note that since the failure of the master results
+only in a gradual divergence of clock values, the election
+need not occur immediately.
+.PP
+All the communication occurring among time daemons uses the TSP
+protocol.
+While some messages need not be sent in a reliable way,
+most communication in TSP requires reliability not provided by the underlying
+protocol.
+Reliability is achieved by the use of acknowledgements, sequence numbers, and
+retransmission when message losses occur.
+When a message that requires acknowledgment is not acknowledged after
+multiple attempts,
+the time daemon that has sent the message will assume that the
+addressee is down.
+This document will not describe the details of how reliability is
+implemented, but will only point out when
+a message type requires a reliable transport mechanism.
+.PP
+The message format in TSP is the same for all message types;
+however, in some instances, one or more fields are not used. 
+The next section describes the message format.
+The following sections describe
+in detail the different message types, their use and the contents
+of each field.  NOTE:  The message format is likely to change in
+future versions of timed.
+.sp 2
+.SH
+Message Format
+.PP
+All fields are based upon 8-bit bytes.  Fields should be sent in
+network byte order if they are more than one byte long.
+The structure of a TSP message is the following:
+.IP 1)
+A one byte message type.
+.IP 2)
+A one byte version number, specifying the protocol version which the
+message uses.
+.IP 3)
+A two byte sequence number to be used for recognizing duplicate messages
+that occur when messages are retransmitted.
+.IP 4)
+Eight bytes of packet specific data.  This field contains two 4 byte time
+values, a one byte hop count, or may be unused depending on the type
+of the packet.
+.IP 5)
+A zero-terminated string of up to 256 \s-2ASCII\s+2 characters with the name of 
+the machine sending the message.
+.PP
+The following charts describe the message types,
+show their fields, and explain their usages.
+For the purpose of the following discussion, a time daemon can 
+be considered to be in
+one of three states: slave, master, or candidate for election to master.
+Also, the term \fIbroadcast\fP refers to
+the sending of a message to all active time daemons.
+.sp 1

+Type: TSP_ADJTIME (1)
+.sp 1
+.PP
+The master sends this message to a slave to communicate 
+the difference between 
+the clock of the slave and
+the network time the master has just computed. 
+The slave will accordingly
+adjust the time of its machine.
+This message requires an acknowledgment.

+Introduction
+.PP
+The clock synchronization service for 
+the UNIX 4.3BSD operating system is composed of a collection of
+time daemons (\fItimed\fP) running on the machines in a local
+area network.
+The algorithms implemented by the service is based on a master-slave scheme.
+The time daemons communicate with each other using the 
+\fITime Synchronization Protocol\fP (TSP) which
+is built on the DARPA UDP protocol and described in detail in [4].
+.PP
+A time daemon has a twofold function.
+First, it supports the synchronization of the clocks 
+of the various hosts in a local area network.
+Second, it starts (or takes part in) the election that occurs
+among slave time daemons when, for any reason, the master disappears.
+The synchronization mechanism and the election procedure 
+employed by the program \fItimed\fP are described 
+in other documents [1,2,3].
+The next paragraphs are a brief overview of how the time daemon works.
+This document is mainly concerned with the administrative and technical
+issues of running \fItimed\fP at a particular site.
+.PP
+A \fImaster time daemon\fP measures the time
+differences between the clock of the machine on which it 
+is running and those of all other machines.
+The master computes the \fInetwork time\fP as the average of the 
+times provided by nonfaulty clocks.\**
+.FS
+A clock is considered to be faulty when its value 
+is more than a small specified
+interval apart from the majority of the clocks 
+of the other machines [1,2].
+.FE
+It then sends to each \fIslave time daemon\fP the
+correction that should be performed on the clock of its machine.
+This process is repeated periodically.
+Since the correction is expressed as a time difference rather than an 
+absolute time, transmission delays do not interfere with 
+the accuracy of the synchronization.
+When a machine comes up and joins the network,
+it starts a slave time daemon which
+will ask the master for the correct time and will reset the machine's clock
+before any user activity can begin.
+The time daemons are able to maintain a single network time in spite of 
+the drift of clocks away from each other. 
+The present implementation keeps processor clocks synchronized 
+within 20 milliseconds.
+.PP
+To ensure that the service provided is continuous and reliable,
+it is necessary to implement an election algorithm to elect a
+new master should the machine running the current master crash, the master
+terminate (for example, because of a run-time error), or 
+the network be partitioned.
+Under our algorithm, slaves are able to realize when the master has
+stopped functioning and to elect a new master from among themselves.
+It is important to note that, since the failure of the master results
+only in a gradual divergence of clock values, the election
+need not occur immediately.
+.PP
+The machines that are gateways between distinct local area
+networks require particular care.
+A time daemon on such machines may act as a \fIsubmaster\fP.
+This artifact depends on the current inability of
+transmission protocols to broadcast a message on a network
+other than the one to which the broadcasting machine is connected.
+The submaster appears as a slave on one network, and as a master
+on one or more of the other networks to which it is connected.
+.PP
+A submaster classifies each network as one of three types.
+A \fIslave network\fP is a network on which the submaster acts as a slave.
+There can only be one slave network.
+A \fImaster network\fP is a network on which the submaster acts as a master.
+An \fIignored network\fP is any other network which already has a valid master.
+The submaster tries periodically to become master on an ignored
+network, but gives up immediately if a master already exists.
+.SH
+Guidelines
+.PP
+While the synchronization algorithm is quite general, the election
+one, requiring a broadcast mechanism, puts constraints on
+the kind of network on which time daemons can run.
+The time daemon will only work on networks with broadcast capability
+augmented with point-to-point links.
+Machines that are only connected to point-to-point,
+non-broadcast networks may not use the time daemon.
+.PP
+If we exclude submasters, there will normally be, at most, one master time 
+daemon in a local area internetwork.
+During an election, only one of the slave time daemons
+will become the new master.
+However, because of the characteristics of its machine,
+a slave can be prevented from becoming the master.
+Therefore, a subset of machines must be designated as potential 
+master time daemons.
+A master time daemon will require CPU resources
+proportional to the number of slaves, in general, more than
+a slave time daemon, so it may be advisable to limit master time
+daemons to machines with more powerful processors or lighter loads.
+Also, machines with inaccurate clocks should not be used as masters.
+This is a purely administrative decision: an organization may
+well allow all of its machines to run master time daemons.
+.PP
+At the administrative level, a time daemon on a machine
+with multiple network interfaces, may be told to ignore all
+but one network or to ignore one network.
+This is done with the \fI\-n network\fP and \fI\-i network\fP
+options respectively at start-up time.
+Typically, the time daemon would be instructed to ignore all but
+the networks belonging to the local administrative control.
+.PP
+There are some limitations to the current
+implementation of the time daemon.
+It is expected that these limitations will be removed in future releases.
+The constant NHOSTS in /usr/src/etc/timed/globals.h limits the
+maximum number of machines that may be directly controlled by one
+master time daemon.
+The current maximum is 29 (NHOSTS \- 1).
+The constant  must be changed and the program recompiled if a site wishes to
+run \fItimed\fP on a larger (inter)network.
+.PP
+In addition, there is a \fIpathological situation\fP to
+be avoided at all costs, that might occur when
+time daemons run on multiply-connected local area networks.
+In this case, as we have seen, time daemons running on gateway machines
+will be submasters and they will act on some of those 
+networks as master time daemons.
+Consider machines A and B that are both gateways between
+networks X and Y.
+If time daemons were started on both A and B without constraints, it would be
+possible for submaster time daemon A to be a slave on network X
+and the master on network Y, while submaster time daemon B is a slave on 
+network Y and the master on network X.
+This \fIloop\fP of master time daemons will not function properly
+or guarantee a unique time on both networks, and will cause
+the submasters to use large amounts of system resources in the form
+of network bandwidth and CPU time.
+In fact, this kind of \fIloop\fP can also be generated with more
+than two master time daemons,
+when several local area networks are interconnected.
+.SH
+Installation
+.PP
+In order to start the time daemon on a given machine,
+the following lines should be
+added to the \fIlocal daemons\fP section in the file \fI/etc/rc.local\fP:
+.sp 2
+.in 1i
+.nf
+if [ -f /etc/timed ]; then
+	/etc/timed \fIflags\fP & echo -n ' timed' >/dev/console
+fi
+.fi
+.in -1i
+.sp
+.LP
+In any case, they must appear after the network 
+is configured via ifconfig(8).
+.PP
+Also, the file \fI/etc/services\fP should contain the following
+line:
+.sp 2
+.ti 1i
+timed		525/udp		timeserver
+.sp
+.LP
+The \fIflags\fP are:
+.IP "-n network" 13
+to consider the named network.
+.IP "-i network"
+to ignore the named network.
+.IP -t
+to place tracing information in \fI/usr/adm/timed.log\fP.
+.IP -M
+to allow this time daemon to become a master.
+A time daemon run without this option will be forced in the state of
+slave during an election.
+.SH
+Daily Operation
+.PP
+\fITimedc(8)\fP is used to control the operation of the time daemon.
+It may be used to:
+.IP \(bu
+measure the differences between machines' clocks,
+.IP \(bu
+find the location where the master \fItimed\fP is running,
+.IP \(bu
+cause election timers on several machines to expire at the same time,
+.IP \(bu
+enable or  disable  tracing  of  messages  received  by \fItimed\fP.
+.LP
+See the manual page on \fItimed\fP\|(8) and \fItimedc\fP\|(8)
+for more detailed information.
+.PP
+The \fIdate(1)\fP command can be used to set the network date.
+In order to set the time on a single machine, the \fI-n\fP flag
+can be given to date(1).

+#	@(#)CHANGES	5.1 (Berkeley) 5/11/93
+# $FreeBSD$
+
+This new version is almost identical to the timed and timedc code
+that has been shipped for years by a workstation vendor.
+
+Among the many changes:
+
+improve `timedc msite` to accept a list of hostnames.
+
+change slave-masters to answer the packets generated by `timedc msite`
+    with the name of the real master, not their own.  This makes it
+    possible to "chase the chain" of slave servers to the ultimate
+    master.
+
+much improve the log caused by `timedc trace on`:
+    -made `timed -t` work.
+    -suppression of repeated entries, which both slowed down the daemon
+	(sometimes catastrophically) and tended to make disks fill up
+	even more quickly.
+    -better time stamps on log entries
+    -more messages
+    -dump information about slaves, master, and so on each time
+	a message asking the log be turned on is received, and
+	when the log is turned off.
+    -fewer CPU cycles
+
+use a hash table to keep track of slaves, instead of the stupid linear
+    list.  This becomes handy with hundreds of slaves, instead of
+    the original design limit of "a room with a few VAX's."
+
+separate the main protocol timer from that used to look for other networks
+    to master.
+
+time stamp packets received by the daemon, so that time corrections
+    are not made (even more) inaccurate by waiting in the internal,
+    timed queue while the daemon is processing other messages.
+
+made -n and -i work with subnets not named in /etc/networks
+
+compute the median of the measured clocks, instead of the average
+    of "good" times.
+
+vastly improve the accuracy of the clock difference measure by 
+    `timedc clockdiff`.
+
+use adjtime() when possible, and directly set the clock only when
+    necessary.
+
+when the requested adjustment is small, perform only part of it, to
+    damp oscillations and improve the long term accuracy of the
+    adjustments.
+
+fix uncounted core-dumps on machines that do not allow dereferencing 0
+    in both the daemon and timedc.
+
+fix "master loop detection".
+
+fix several cases in which multi-homed masters could get into shouting 
+    matches, consuming all available network bandwidth and CPU cycles
+    (which ever runs out first), and convincing all bystanders to stop
+    advancing their own clocks.
+
+refuse to behave badly when other machines do.  Instead of arguing forever,
+    go off and sulk when other machines refuse to play by the rules.
+
+increase the maximum number of clients.
+
+add "-F host,host2,..." to "freerun" or "trust" only some hosts.  This
+    is handy both when only some machines should be trusted to let
+    root use the `date` command to change time in the network.
+
+    It is also handy when one machine has some other way of adjusting
+    its clock, whether NTP or a direct radio or atomic connection.
+    "-F localhost" causes `timed` to "trust" only itself.
+
+    It is also handy to build a hierarchy of timed masters crossing
+    networks.  The TSP protocol has no provision of "goodness of clock",
+    no natural way to completely heal network paritions.  Judicious
+    use of -F or -G can cause each gateway to trust only itself and
+    machines closer to a central machine with a radio or atomic clock.
+
+add #ifdef code that supports NIS "netgroups" of trusted hosts, which
+    can be easier to administer than -F.
+
+add #ifdef code to compute an aged total adjustment.  This can be used
+    in systems that can make long term changes in their system clock
+    frequency, e.g. "timetrim" in the Silicon Graphics kernel.
+
+
+Problems observed by others that are unresolved include:
+
+Practically any users can send to the master TSP messages and this
+	way corrupt the reliability of the system.  Authentication
+	of messages should be provided.  Unfortunately, that would
+	require changing the protocol with all of the implied
+	compatiblity problems.  Fortunately, the new -F and -G args
+	can be used to cause the daemon to ignore time changes from
+	untrusted machines.
+
+MAN.	The limit of 1013 on the number of slaves hosts should be doc'ed.
+
+	It should be dynamically allocated with no limit.  On a
+	large network, one host could possibly master over many
+	more than 30 hosts.   Given the timers in the code and
+	effectively in the protocol, and the time required by each
+	master to talk to each slave, it is not practical to have
+	more than 200-300 slaves.  The master cannot keep up because
+	the slave-chatting is single-threaded.  when the master
+	gets behind, slaves start demanding elections.  To
+	significantly increase the number of slaves would require
+	multi-treading things, and given that a network with more
+	than 300 directly addressable machines has worse problems
+	than keep the time of day right, not worth worrying about.
+
+UGLY,CODE. timedc/cmds.c has a lots of repeated code in it.
+
+****    The first thing is that each command is set up as if it
+	were an individual program taking argc and argv.  A more
+	conventional calling style should be used.  I don't think
+	any of the routines take more than a couple arguments.
+
+UGLY.	fxn definition syntax does't follow convention:
+	has type on same line.
+
+****	It needs to be fixed at least enough that tags
+	will work on it.  An entire cleanup might be nice later, but
+	is noncritical.
+
+LOBBY(mildly),CODE:	Would be very convenient if date(1) took a
+	+-<number> argument to set the time relatively.  With
+	the advent of timed it is now reasonable to synchronize
+	with WWV, which is nearly impossible to do "by hand"
+	with just an absolute date, and scripts are too slow.
+	format could be +-nn...nn.ss, where the '.' is required
+	to remove ambiguity.
+
+****	If you want to do it go ahead.  It sounds useful.  As far as
+	syntax goes, the normal format for the date should work just
+	fine for this.  If the date is preceded by a plus or minus,
+	the change is relative, otherwise it is absolute.

+.Nm timed
+.Nd time server daemon
+.Sh SYNOPSIS
+.Nm
+.Op Fl dtM
+.Op Fl i Ar network
+.Op Fl n Ar network
+.Op Fl F Ar host ...
+.Sh DESCRIPTION
+The
+.Nm
+daemon is a time server daemon
+which is normally invoked at boot time from the
+.Xr rc.network 8
+file.
+It synchronizes the host's time with the time of other
+machines, which are also running
+.Nm ,
+in a local area network.
+These time servers will slow down the clocks of some machines
+and speed up the clocks of others to bring them to the average network time.
+The average network time is computed from measurements of clock differences
+using the
+.Tn ICMP
+timestamp request message.
+.Pp
+The following options are available:
+.Bl -tag -width indent
+.It Fl d
+Enable debugging mode;
+do not detach from the terminal.
+.It Fl i Ar network
+Add
+.Ar network
+to the list of networks to ignore.
+All other networks
+to which the machine is directly connected
+are used by
+.Nm .
+This option may be specified multiple times
+to add more than one network to the list.
+.It Fl F Ar host ...
+Create a list of trusted hosts.
+.Nm
+will only accept trusted hosts as masters.
+If it finds an untrusted host claiming to be master,
+.Nm
+will suppress incoming messages from that host
+and call for a new election.
+This option implies the
+.Fl M
+option.
+If this option is not specified,
+all hosts on the connected networks are treated as trustworthy.
+.It Fl M
+Allow this host to become a
+.Nm
+master if necessary.
+.It Fl n Ar network
+Add
+.Ar network
+to the list of allowed networks.
+All other networks
+to which the machine is directly connected
+are ignored by
+.Nm .
+This option may be specified multiple times
+to add more than one network to the list.
+.It Fl t
+Enable tracing of received messages
+and log to the file
+.It Pa /var/log/timed.log .
+Tracing can be turned on or off while
+.Nm
+is running with the
+.Xr timedc 8
+utility.
+.El
+.Pp
+The
+.Fl n
+and
+.Fl i
+are mutually exclusive
+and require as arguments real networks to which
+the host is connected
+(see
+.Xr networks 5 ) .
+If neither flag is specified,
+.Nm
+will listen on all connected networks.
+.Pp
+A
+.Nm
+running without the
+.Fl M
+nor
+.Fl F
+flags will always remain a slave.
+If the
+.Fl F
+flag is not used,
+.Nm
+will treat all machines as trustworthy.
+.Pp
+.Nm
+is based on a master-slave
+scheme.
+When
+.Nm
+is started on a machine, it asks the master for the network time
+and sets the host's clock to that time.
+After that, it accepts synchronization messages periodically sent by
+the master and calls
+.Xr adjtime 2
+to perform the needed corrections on the host's clock.
+.Pp
+It also communicates with
+.Xr date 1
+in order to set the date globally,
+and with
+.Xr timedc 8 ,
+a
+.Nm
+control program.
+If the machine running the master becomes unreachable,
+the slaves will elect a new master
+from among those slaves
+which are running with at least one of the
+.Fl M
+and
+.Fl F
+flags.
+.Pp
+At startup
+.Nm
+normally checks for a master time server on each network to which
+it is connected, except as modified by the
+.Fl n
+and
+.Fl i
+options described above.
+It will request synchronization service from the first master server
+located.
+If permitted by the
+.Fl M
+or
+.Fl F
+flags, it will provide synchronization service on any attached networks
+on which no trusted master server was detected.
+Such a server propagates the time computed by the top-level master.
+.Nm
+will periodically check for the presence of a master
+on those networks for which it is operating as a slave.
+If it finds that there are no trusted masters on a network,
+it will begin the election process on that network.
+.Pp
+One way to synchronize a group of machines is to use an
+.Tn NTP
+daemon to
+synchronize the clock of one machine to a distant standard or a radio
+receiver and
+.Fl F Ar hostname
+to tell its timed daemon to trust only itself.
+.Pp
+Messages printed by the kernel on the system console occur with
+interrupts disabled.
+This means that the clock stops while they are printing.
+A machine with many disk or network hardware problems and consequent
+messages cannot keep good time by itself.  Each message typically causes
+the clock to lose a dozen milliseconds.  A time daemon can
+correct the result.
+.Pp
+Messages in the system log about machines that failed to respond
+usually indicate machines that crashed or were turned off.
+Complaints about machines that failed to respond to initial time
+settings are often associated with "multi-homed" machines
+that looked for time masters on more than one network and eventually
+chose to become a slave on the other network.
+.Sh WARNINGS
+Temporal chaos will result if two or more time daemons attempt
+to adjust the same clock.
+If both
+.Nm
+and another time daemon are run on the same machine,
+ensure that the
+.Fl F
+flag is used, so that
+.Nm
+never attempts to adjust the local clock.
+.Pp
+The protocol is based on
+.Tn UDP/IP
+broadcasts.  All machines within
+the range of a broadcast that are using the
+.Tn TSP
+protocol must cooperate.
+There cannot be more than a single administrative domain using the
+.Fl F
+flag among all machines reached by a broadcast packet.
+Failure to follow this rule is usually indicated by complaints concerning
+"untrusted" machines in the system log.

+ * local time (rather than GMT) without setting the high order bit.
+ * Furthermore, it does not understand daylight-saving time.  This makes
+ * clockdiff behaving inconsistently with hosts running VMS.
+ *
+ * In order to reduce the sensitivity to the variance of message transmission
+ * time, clockdiff sends a sequence of messages.  Yet, measures between

+.Nm timedc
+.Nd timed control program
+.Sh SYNOPSIS
+.Nm
+.Op Ar command Op Ar argument ...
+.Sh DESCRIPTION
+.Nm Timedc
+is used to control the operation of the
+.Xr timed 8
+program.
+It may be used to:
+.Bl -bullet
+.It
+Measure the differences between machines' clocks,
+.It
+Find the location where the master time server is running,
+.It
+Enable or disable tracing of messages received by
+.Xr timed 8 ,
+and
+.It
+Perform various debugging actions.
+.El
+.Pp
+Without any arguments,
+.Nm
+will prompt for commands from the standard input.
+If arguments are supplied,
+.Nm
+interprets the first argument as a command and the remaining
+arguments as parameters to the command.  The standard input
+may be redirected causing
+.Nm
+to read commands from a file.
+Commands may be abbreviated;
+recognized commands are:
+.Pp
+.Bl -tag -width Ds -compact
+.It Ic \&? Op Ar command ...
+.Pp
+.It Ic help Op Ar command ...
+Print a short description of each command specified in the argument list,
+or, if no arguments are given, a list of the recognized commands.
+.Pp
+.It Ic clockdiff Ar host ...
+Compute the differences between the clock of the host machine
+and the clocks of the machines given as arguments.
+.Pp
+.It Ic msite Op Ar host ...
+Show the master time server for specified host(s).
+.Pp
+.It Xo
+.Ic trace
+.Li \&{ Ar on Li \&|
+.Ar off \&}
+.Xc
+Enable or disable the tracing of incoming messages to
+.Xr timed
+in the file
+.Pa /var/log/timed.log .
+.Pp
+.It Ic election Ar host1 Op Ar host2 ...
+Asks the daemon
+on the target host to reset its "election" timers and to ensure that
+a time master has been elected.
+.Pp
+.It Ic quit
+Exit from timedc.
+.El
+.Pp
+Other commands may be included for use in testing and debugging
+.Xr timed 8 ;
+the help command and
+the program source may be consulted for details.

+ * traceroute host  - trace the route ip packets follow going to "host".
+ *
+ * Attempt to trace the route an ip packet would follow to some
+ * internet host.  We find out intermediate hops by launching probe
+ * packets with a small ttl (time to live) then listening for an
+ * icmp "time exceeded" reply from a gateway.  We start our probes
+ * with a ttl of one and increase by one until we get an icmp "port
+ * unreachable" (which means we got to "host") or hit a max (which
+ * defaults to 30 hops & can be changed with the -m flag).  Three
+ * probes (change with -q flag) are sent at each ttl setting and a
+ * line is printed showing the ttl, address of the gateway and
+ * round trip time of each probe.  If the probe answers come from
+ * different gateways, the address of each responding system will
+ * be printed.  If there is no response within a 5 sec. timeout
+ * interval (changed with the -w flag), a "*" is printed for that
+ * probe.
+ *
+ * Probe packets are UDP format.  We don't want the destination
+ * host to process them so the destination port is set to an
+ * unlikely value (if some clod on the destination is using that
+ * value, it can be changed with the -p flag).
+ *
+ * A sample use might be:
+ *
+ *     [yak 71]% traceroute nis.nsf.net.
+ *     traceroute to nis.nsf.net (35.1.1.48), 30 hops max, 56 byte packet

+ * (I start to see why I'm having so much trouble with mail to
+ * MIT.)  Note that the gateways 12, 14, 15, 16 & 17 hops away
+ * either don't send ICMP "time exceeded" messages or send them
+ * with a ttl too small to reach us.  14 - 17 are running the
+ * MIT C Gateway code that doesn't send "time exceeded"s.  God
+ * only knows what's going on with 12.
+ *
+ * The silent gateway 12 in the above may be the result of a bug in
+ * the 4.[23]BSD network code (and its derivatives):  4.x (x <= 3)
+ * sends an unreachable message using whatever ttl remains in the
+ * original datagram.  Since, for gateways, the remaining ttl is
+ * zero, the icmp "time exceeded" is guaranteed to not make it back
+ * to us.  The behavior of this bug is slightly more interesting
+ * when it appears on the destination system:
+ *
+ *      1  helios.ee.lbl.gov (128.3.112.1)  0 ms  0 ms  0 ms

+ *     12  * * *
+ *     13  rip.Berkeley.EDU (128.32.131.22)  59 ms !  39 ms !  39 ms !
+ *
+ * Notice that there are 12 "gateways" (13 is the final
+ * destination) and exactly the last half of them are "missing".
+ * What's really happening is that rip (a Sun-3 running Sun OS3.5)
+ * is using the ttl from our arriving datagram as the ttl in its
+ * icmp reply.  So, the reply will time out on the return path
+ * (with no notice sent to anyone since icmp's aren't sent for
+ * icmp's) until we probe with a ttl that's at least twice the path
+ * length.  I.e., rip is really only 7 hops away.  A reply that
+ * returns with a ttl of 1 is a clue this problem exists.
+ * Traceroute prints a "!" after the time if the ttl is <= 1.
+ * Since vendors ship a lot of obsolete (DEC's Ultrix, Sun 3.x) or
+ * non-standard (HPUX) software, expect to see this problem
+ * frequently and/or take care picking the target host of your
+ * probes.
+ *
+ * Other possible annotations after the time are !H, !N, !P (got a host,
+ * network or protocol unreachable, respectively), !S or !F (source
+ * route failed or fragmentation needed -- neither of these should
+ * ever occur and the associated gateway is busted if you see one).  If
+ * almost all the probes result in some kind of unreachable, traceroute
+ * will give up and exit.
+ *
+ * Notes
+ * -----
+ * This program must be run by root or be setuid.  (I suggest that
+ * you *don't* make it setuid -- casual use could result in a lot
+ * of unnecessary traffic on our poor, congested nets.)
+ *
+ * This program requires a kernel mod that does not appear in any
+ * system available from Berkeley:  A raw ip socket using proto
+ * IPPROTO_RAW must interpret the data sent as an ip datagram (as
+ * opposed to data to be wrapped in a ip datagram).  See the README
+ * file that came with the source to this program for a description
+ * of the mods I made to /sys/netinet/raw_ip.c.  Your mileage may
+ * vary.  But, again, ANY 4.x (x < 4) BSD KERNEL WILL HAVE TO BE
+ * MODIFIED TO RUN THIS PROGRAM.
+ *
+ * The udp port usage may appear bizarre (well, ok, it is bizarre).
+ * The problem is that an icmp message only contains 8 bytes of
+ * data from the original datagram.  8 bytes is the size of a udp
+ * header so, if we want to associate replies with the original
+ * datagram, the necessary information must be encoded into the
+ * udp header (the ip id could be used but there's no way to
+ * interlock with the kernel's assignment of ip id's and, anyway,
+ * it would have taken a lot more kernel hacking to allow this
+ * code to set the ip id).  So, to allow two or more users to
+ * use traceroute simultaneously, we use this task's pid as the
+ * source port (the high bit is set to move the port number out
+ * of the "likely" range).  To keep track of which probe is being
+ * replied to (so times and/or hop counts don't get confused by a
+ * reply that was delayed in transit), we increment the destination
+ * port number before each probe.
+ *
+ * Don't use this as a coding example.  I was trying to find a
+ * routing problem and this code sort-of popped out after 48 hours
+ * without sleep.  I was amazed it ever compiled, much less ran.
+ *
+ * I stole the idea for this program from Steve Deering.  Since
+ * the first release, I've learned that had I attended the right
+ * IETF working group meetings, I also could have stolen it from Guy
+ * Almes or Matt Mathis.  I don't know (or care) who came up with
+ * the idea first.  I envy the originators' perspicacity and I'm
+ * glad they didn't keep the idea a secret.
+ *
+ * Tim Seaver, Ken Adelman and C. Philip Wood provided bug fixes and/or
+ * enhancements to the original distribution.
+ *
+ * I've hacked up a round-trip-route version of this that works by
+ * sending a loose-source-routed udp datagram through the destination
+ * back to yourself.  Unfortunately, SO many gateways botch source
+ * routing, the thing is almost worthless.  Maybe one day...

+.Ar system Op Ar core
+.Oc
+.Sh DESCRIPTION
+.Nm Trpt
+interrogates the buffer of
+.Tn TCP
+trace records created
+when a socket is marked for
+.Dq debugging
+(see
+.Xr setsockopt 2 ) ,
+and prints a readable description of these records.
+When no options are supplied,
+.Nm
+prints all the trace records found in the system
+grouped according to
+.Tn TCP
+connection protocol control
+block
+.Pq Tn PCB .
+.Pp
+The following options may be used to
+alter this behavior:
+.Bl -tag -width indent
+.It Fl a
+In addition to the normal output,
+print the values of the source and destination
+addresses for each packet recorded.
+.It Fl f
+Follow the trace as it occurs, waiting a short time for additional records
+each time the end of the log is reached.
+.It Fl j
+Just give a list of the protocol control block
+addresses for which there are trace records.
+.It Fl p
+Show only trace records associated with the protocol
+control block at the given address
+.Ar hex-address .
+.It Fl s
+In addition to the normal output,
+print a detailed description of the packet
+sequencing information.
+.It Fl t
+In addition to the normal output,
+print the values for all timers at each
+point in the trace.
+.El
+.Pp
+The recommended use of
+.Nm
+is as follows.
+Isolate the problem and enable debugging on the
+socket(s) involved in the connection.
+Find the address of the protocol control blocks
+associated with the sockets using the
+.Fl A
+option to
+.Xr netstat 1 .
+Then run
+.Nm
+with the
+.Fl p
+option, supplying the associated
+protocol control block addresses.
+The
+.Fl f
+option can be used to follow the trace log once the trace is located.
+If there are
+many sockets using the debugging option, the
+.Fl j
+option may be useful in checking to see if
+any trace records are present for the socket in
+question.
+.Pp
+If debugging is being performed on a system or
+core file other than the default, the last two
+arguments may be used to supplant the defaults.
+.Sh FILES
+.Bl -tag -width /boot/kernel/kernel -compact
+.It Pa /boot/kernel/kernel
+.It Pa /dev/kmem
+.El
+.Sh SEE ALSO
+.Xr netstat 1 ,
+.Xr setsockopt 2
+.Sh DIAGNOSTICS
+.Bl -diag
+.It no namelist
+When the system image doesn't
+contain the proper symbols to find the trace buffer;
+others which should be self explanatory.
+.El
+.Sh BUGS
+Should also print the data for each input or output,
+but this is not saved in the trace record.
+.Pp
+The output format is inscrutable and should be described
+here.
+.Sh HISTORY
+The
+.Nm
+command appeared in

+.Sh NAME
+.Nm tzsetup
+.Nd set local timezone
+.Sh SYNOPSIS
+.Nm
+.Op Fl n
+.Op Ar default
+.Sh DESCRIPTION
+The
+.Nm
+program reads a database of timezone information and presents a menu
+allowing the user to select a specific zone without knowing the details
+of the database layout.  The selected zone is installed as the system
+default zone.
+.Nm
+also determines whether any adjustment is necessary for systems where
+the hardware clock does not keep
+.Tn UTC .
+.Pp
+The following option is available:
+.Bl -tag -offset indent -width Fl
+.It Fl n
+Do not create or copy files.
+.El
+.Pp
+It is possible to short-circuit the menu system by specifying a
+.Ar default
+on the command line; this is intended mainly for pre-configured
+installation scripts.
+.Sh TIMEZONE DATABASE
+The contents of the timezone database are indexed by
+.Pa /usr/share/zoneinfo/zone.tab .
+This file lists, for each timezone data file, the
+.Tn ISO
+3166 territory code, approximate geographical coordinates
+(in
+.Tn ISO
+6709 format),
+and location within the territory.
+.Pp
+The maintainers of the database maintain the following policies:
+.Bl -enum -offset indent
+.It
+At least one zone for every country or inhabited geographical territory.
+.It
+One zone for every distinct, documented timezone history since the
+beginning of the
+.Ux
+epoch (January 1, 1970,
+.Tn GMT ) .
+.It
+Each zone is named for the most populous city therein.  (Where possible,
+the database includes pre-1970 history for its city.)
+.El
+The source code to the database
+.Pq Pa /usr/src/share/zoneinfo/[a-z]*
+contains many additional comments and documentation references for the
+historically minded.
+.Sh BUGS
+Programs which are already running when
+.Nm
+creates or updates
+.Pa /etc/localtime
+will not reflect the updated timezone.
+When the system is first configured for a
+.Pf non- Tn UTC
+hardware clock, it is necessary to run
+.Xr adjkerntz 8
+(which normally happens as a part of system startup) in order to update
+the kernel's idea of the correct timezone offset.
+.Sh FILES
+.Bl -tag -width /usr/share/zoneinfo/zone.tab -compact
+.It Pa /etc/localtime
+current time zone file
+.It Pa /etc/wall_cmos_clock
+see
+.Xr adjkerntz 8 .
+.It Pa /usr/share/misc/iso3166
+mapping of
+.Tn ISO
+3166 territory codes to names
+.It Pa /usr/share/zoneinfo
+directory for zoneinfo files
+.It Pa /usr/share/zoneinfo/zone.tab
+mapping of timezone file to country and location
+.El
+.Sh SEE ALSO
+.Xr date 1 ,
+.Xr adjtime 2 ,
+.Xr ctime 3 ,
+.Xr timezone 3 ,

+.Sh DISCLAIMER
+The representation of certain localities as being associated with certain
+countries and/or territories is for the purposes of identification only,
+and does not imply any endorsement or rejection on the part of the
+.Fx
+Project of the territorial claims of any entity.

+.Nm
+.Op Fl c Ar configfile
+.Op Fl d
+.Op Fl e
+.Op Fl f Ar device
+.Op Fl n
+.Op Fl t Ar timeout
+.Op Fl v
+.Sh DESCRIPTION
+.Nm
+handles the USB device attachment and detachment.
+It does two things.
+Through opening the
+.Pa /dev/usb0 ,
+.Pa /dev/usb1 ,
+etc. devices, it enables the kernel to do handle change requests from
+attached hubs.
+This functionality will be removed when the kernel has
+kernel threads.
+The (multiple)
+.Fl f Ar device
+command line options specify which controllers it should handle.
+Normally this option is not needed.
+.Pp
+If the
+.Dq usb ,
+.Dq ohci
+and
+.Dq uhci
+modules are not loaded, it will load them automatically.
+.Pp
+The second part is the handling of the attachment and detachment of USB
+devices.
+The device
+.Pa /dev/usb
+is opened and events are read from it.
+Whenever a device is attached or
+detached the list of actions read from
+.Pa /etc/usbd.conf
+are searched for a matching entry.
+If found, the corresponding action is
+executed.
+.Pp
+The command line options are as follows:
+.Bl -tag -width Ds
+.It Fl c Ar filename
+Name of configuration file.
+The default is
+.Pa /etc/usbd.conf .
+.It Fl d
+Enable debugging to the standard output,
+and do not disassociate from the controlling terminal.
+.It Fl e
+Do one device tree exploration, no event queue handling and then exit.
+.It Fl f Ar device
+Specify the pathname of a USB controller device file.
+The flag may be repeated to watch more than one USB controller.
+The default is
+.Pa /dev/usb0
+through
+.Pa /dev/usb3 .
+Do not specify the device
+.Pa /dev/usb
+here.
+It is used for events only.
+.It Fl n
+Do not handle the event queue on /dev/usb.
+.It Fl t Ar timeout
+Set the timeout interval (in seconds) before an exploration happens
+without being triggered by a connect or disconnect.
+A timeout of 0 means that there is no timeout.  The default is 30.
+.It Fl v
+Be verbose.
+Repeating the flag makes
+.Nm
+more verbose.

+.Sh NAME
+.Nm usbd.conf
+.Nd
+.Xr usbd 8
+configuration file
+.Sh DESCRIPTION
+The
+.Nm
+file is the configuration file for the
+.Xr usbd 8
+daemon.
+It provides information to allow execution of userland commands
+on events reported by the
+.Xr usb 4
+subsystem in the kernel.
+Currently the only events are device attach and
+detach, but could in the future be extended to include power management
+functions.
+.Pp
+The configuration file consists of a sorted list of entries.
+Each entry
+describes a set of criteria commands.
+When an event occurs, the criteria
+are checked and if met, the commands for that event are executed through
+a shell.
+The list is sorted and scanned from top to bottom.
+The first
+matching entry is used for an event.
+.Pp
+Each entry contains a number of fields.
+There are 3 types of fields:
+descriptive fields, selection criteria and commands to execute on
+events.
+The field name is case sensitive and should be all lower case.
+Each field can have one or more arguments.
+.Pp
+The following fields are available:
+.Bl -tag -width devicename\ <Id>
+.It device Ar string
+Start a new entry.
+.Ar string
+is an arbitrary string used for pretty printing.
+.It product Ar id
+Product Id
+.It vendor Ar id
+Vendor Id
+.It release Ar id
+Release Id, also called revision Id sometimes.
+.It class Ar id
+Device Class
+.It subclass Ar id
+Device Subclass
+.It protocol Ar id
+Device Protocol
+.It devname Ar string
+Device name, for example umass2, or ums0. These device names can contain
+regular expressions.
+See
+.Xr regex 3
+and
+.Xr re_format 7 .
+The device name that is matched can be used in the commands below
+through adding ${DEVNAME} somewhere in that string.
+.El
+.Pp
+String arguments may be quoted.
+If a string argument contains a space or
+tab character it needs to be enclosed in single or double quotes.
+If an
+argument contains a single or double quote, that quote needs to be
+enclosed in double or single quotes respectively.
+See below for
+examples.
+.Pp
+Numeric arguments can either be specified in decimal (42), octal (052) or
+hexadeximal (0x2a).
+.Pp
+The values for the fields
+.Li product , vendor , release, class , subclass
+and
+.Li protocol
+can be retrieved by killing the
+.Nm usbd
+daemon and running it with the
+.Fl d
+and
+.Fl v
+flags.
+.Pp
+Commands to be executed when the action is matched:
+.Bl -tag -width devicename\ <Id>
+.It attach Ar string
+Shell command to execute when a device is attached.
+.It detach Ar string
+Shell command to execute when a device is detached.
+.El
+.Sh EXAMPLES
+A sample entry to rescan the SCSI bus on connection of a
+.Tn "Iomega USB Zip Drive" :
+.Bd -literal
+   device "USB Zip drive"
+      product 0x0001
+      vendor  0x059b
+      release 0x0100
+      attach "/usr/bin/camcontrol rescan bus 0"
+.Ed
+.Pp
+To start up moused for a newly attached mouse:
+.Bd -literal
+   device "Mouse"
+      devname "ums[0-9]+"
+      attach "/usr/sbin/moused -p /dev/${DEVNAME} -I /var/run/moused.${DEVNAME}.pid"

+below.
+.It Ar foreground Op Ar background
+Change colors when displaying text.
+Specify the foreground color
+(e.g.\&
+.Dq vidcontrol white ) ,
+or both a foreground and background colors
+(e.g.\&
+.Dq vidcontrol yellow blue ) .
+Use the
+.Cm show

+The font file can be either uuencoded or in raw binary format.
+You can also use the menu-driven
+.Xr vidfont 1
+command to load the font of your choice.
+.Pp
+.Ar Size
+may be omitted, in this case
+.Nm
+will try to guess it from the size of font file.
+.Pp
+Note that older video cards, such as MDA and CGA, do not support
+software font.
+See also
+.Sx Video Mode Support
+and
+.Sx EXAMPLES
+below and the man page for
+.Xr syscons 4 .
+.It Fl g Ar geometry
+Set the
+.Ar geometry
+of the text mode for the modes with selectable

+or
+.Cm off .
+Used together with the
+.Xr moused 8
+daemon for text mode cut & paste functionality.
+.It Fl p
+Capture the current contents of the video buffer corresponding
+to the terminal device referred to by standard input.
+The
+.Nm
+utility writes contents of the video buffer to the standard
+output in a raw binary format.
+For details about that
+format see
+.Sx Format of Video Buffer Dump
+below.
+.It Fl P
+Same as
+.Fl p ,
+but dump contents of the video buffer in a plain text format
+ignoring nonprintable characters and information about text
+attributes.
+.It Fl r Ar foreground background
+Change reverse mode colors to
+.Ar foreground
+and
+.Ar background .
+.It Fl s Ar number
+Set the current vty to
+.Ar number .
+.It Fl t Ar N | Cm off
+Set the screensaver timeout to
+.Ar N
+seconds, or turns it
+.Cm off .
+.It Fl x
+Use hexadecimal digits for output.
+.El
+.Ss Video Mode Support
+Note that not all modes listed above may be supported by the video
+hardware.
+You can verify which mode is supported by the video hardware, using the
+.Fl i Cm mode
+option.
+.Pp
+The VESA BIOS support must be linked to the kernel
+or loaded as a KLD module if you wish to use VESA video modes
+or 132 column modes
+(see
+.Xr vga 4 ) .
+.Pp
+You need to compile your kernel with the
+.Ar VGA_WIDTH90
+option if you wish to use VGA 90 column modes
+(see
+.Xr vga 4 ) .
+.Pp
+Video modes other than 25 and 30 line modes may require specific size of font.
+Use
+.Fl f
+option above to load a font file to the kernel.
+If the required size of font has not been loaded to the kernel,
+.Nm
+will fail if the user attempts to set a new video mode.
+.Pp
+.Bl -column "25 line modes" "8x16 (VGA), 8x14 (EGA)" -compact

+.Li 60 line modes Ta 8x8
+.El
+.Pp
+It is better to always load all three sizes (8x8, 8x14 and 8x16)
+of the same font.
+.Pp
+You may set variables in
+.Pa /etc/rc.conf
+or
+.Pa /etc/rc.conf.local
+so that desired font files will be automatically loaded
+when the system starts up.
+See below.
+.Pp
+If you want to use the raster text mode
+.Ar VESA_800x600 ,
+you need to recompile your kernel with the
+.Dv SC_PIXEL_MODE
+option.
+See
+.Xr syscons 4
+for more details on this kernel option.
+.Ss Format of Video Buffer Dump
+The
+.Nm
+utility uses the
+.Xr syscons 4
+.Dv CONS_SCRSHOT
+.Xr ioctl 2
+to capture the current contents of the video buffer.
+The
+.Nm
+utility writes version and additional information to the standard
+output, followed by the contents of the terminal device.
+.Pp
+VGA video memory is typically arranged in two byte tuples,
+one per character position.
+In each tuple, the first byte will be the character code,
+and the second byte is the character's color attribute.
+.Pp
+The VGA color attribute byte looks like this:
+.Pp
+.Bl -column "X:X" "<00000000>" "width" "bright foreground color"
+.Sy "bits#		width	meaning"
+.Li "7	<X0000000>	1	character blinking"
+.Li "6:4	<0XXX0000>	3	background color"
+.Li "3	<0000X000>	1	bright foreground color"
+.Li "2:0	<00000XXX>	3	foreground color"
+.El
+.Pp
+Here is a list of the three bit wide base colors:
+.Pp
+.Bl -hang -offset indent -compact
+.It 0
+Black
+.It 1
+Blue
+.It 2
+Green
+.It 3
+Cyan
+.It 4
+Red
+.It 5
+Magenta
+.It 6
+Brown
+.It 7
+Light Grey
+.El
+.Pp
+Base colors with bit 3 (the bright foreground flag) set:
+.Pp
+.Bl -hang -offset indent -compact
+.It 0
+Dark Grey
+.It 1
+Light Blue
+.It 2
+Light Green
+.It 3
+Light Cyan
+.It 4
+Light Red
+.It 5
+Light Magenta
+.It 6
+Yellow
+.It 7
+White
+.El
+.Pp
+For example, the two bytes
+.Pp
+.Dl "65 158"
+.Pp
+specify an uppercase A (character code 65), blinking
+(bit 7 set) in yellow (bits 3:0) on a blue background
+(bits 6:4).
+.Pp
+The
+.Nm
+output contains a small header which includes additional
+information which may be useful to utilities processing
+the output.
+.Pp
+The first 10 bytes are always arranged as follows:
+.Bl -column "Byte range" "Contents" -offset indent
+.It Sy "Byte Range	Contents"
+.It "1 thru 8	Literal text" Dq Li SCRSHOT_
+.It "9	File format version number"
+.It "10	Remaining number of bytes in the header"
+.El
+.Pp
+Subsequent bytes depend on the version number.
+.Bl -column "Version" "13 and up" -offset indent
+.It Sy "Version	Byte	Meaning"
+.It "1	11	Terminal width, in characters"
+.It "	12	Terminal depth, in characters"
+.It "	13 and up	The snapshot data"
+.El
+.Pp
+So a dump of an 80x25 screen would start (in hex)
+.Bd -literal -offset indent

+.Sh VIDEO OUTPUT CONFIGURATION
+.Ss Boot Time Configuration
+You may set the following variables in
+.Pa /etc/rc.conf
+or
+.Pa /etc/rc.conf.local
+in order to configure the video output at boot time.
+.Pp
+.Bl -tag -width foo_bar_var -compact
+.It Ar blanktime
+Sets the timeout value for the
+.Fl t
+option.
+.It Ar font8x16 , font8x14 , font8x8
+Specifies font files for the
+.Fl f
+option.
+.It Ar scrnmap
+Specifies a screen output map file for the
+.Fl l
+option.
+.El
+.Pp
+See
+.Xr rc.conf 5
+for more details.
+.Ss Driver Configuration
+The video card driver may let you change default configuration
+options, such as the default font, so that you do not need to set up
+the options at boot time.
+See video card driver manuals, (e.g.\&
+.Xr vga 4 )
+for details.
+.Sh FILES
+.Bl -tag -width /usr/share/syscons/scrnmaps/foo-bar -compact

+.Sh EXAMPLES
+If you want to load
+.Pa /usr/share/syscons/fonts/iso-8x16.fnt
+to the kernel, run
+.Nm
+as:
+.Pp
+.Dl vidcontrol -f 8x16 /usr/share/syscons/fonts/iso-8x16.fnt
+.Pp
+So long as the font file is in
+.Pa /usr/share/syscons/fonts ,
+you may abbreviate the file name as
+.Pa iso-8x16 :
+.Pp
+.Dl vidcontrol -f 8x16 iso-8x16
+.Pp
+Furthermore, you can also omit font size
+.Dq Li 8x16 :
+.Pp
+.Dl vidcontrol -f iso-8x16
+.Pp
+Moreover, the suffix specifying the font size can be also omitted; in
+this case,
+.Nm
+will use the size of the currently displayed font to construct the
+suffix:
+.Pp
+.Dl vidcontrol -f iso
+.Pp
+Likewise, you can also abbreviate the screen output map file name for
+the
+.Fl l
+option if the file is found in
+.Pa /usr/share/syscons/scrnmaps .
+.Pp
+.Dl vidcontrol -l iso-8859-1_to_cp437
+.Pp
+The above command will load
+.Pa /usr/share/syscons/scrnmaps/iso-8859-1_to_cp437.scm .
+.Pp
+The following command will set-up a 100x37 raster text mode (useful for
+some LCD models):
+.Pp
+.Dl vidcontrol -g 100x37 VESA_800x600
+.Pp
+The following command will capture the contents of the first virtual
+terminal, and redirect the output to the
+.Pa shot.scr
+file:
+.Pp
+.Dl vidcontrol -p < /dev/ttyv0 > shot.scr
+.Pp
+The following command will dump contents of the fourth virtual terminal
+to the standard output in the human readable format:
+.Pp
+.Dl vidcontrol -P < /dev/ttyv3

+.Sh NAME
+.Nm vipw
+.Nd edit the password file
+.Sh SYNOPSIS
+.Nm
+.Op Fl d Ar directory
+.Sh DESCRIPTION
+.Nm Vipw
+edits the password file after setting the appropriate locks,
+and does any necessary processing after the password file is unlocked.
+If the password file is already locked for editing by another user,
+.Nm
+will ask you
+to try again later.
+The default editor for
+.Nm
+is
+.Xr vi 1 .
+.Pp
+When run without options,
+.Nm
+will work with the password files in
+.Pa /etc .
+The
+.Fl d
+option may be used to specify an alternative
+.Ar directory
+to work with.
+.Pp
+.Nm Vipw
+performs a number of consistency checks on the password entries,
+and will not allow a password file with a
+.Dq mangled
+entry to be
+installed.
+If
+.Nm
+rejects the new password file, the user is prompted to re-enter
+the edit session.
+.Pp
+Once the information has been verified,
+.Nm
+uses
+.Xr pwd_mkdb 8
+to update the user database.  This is run in the background, and,
+at very large sites could take several minutes.  Until this update
+is completed, the password file is unavailable for other updates
+and the new information is not available to programs.
+.Sh ENVIRONMENT
+If the following environment variable exists it will be utilized by
+.Nm :
+.Bl -tag -width PW_SCAN_BIG_IDS
+.It Ev EDITOR
+The editor specified by the string
+.Ev EDITOR
+will be invoked instead of the default editor
+.Xr vi 1 .
+.It Ev PW_SCAN_BIG_IDS
+See
+.Xr pwd_mkdb 8 .
+.El
+.Sh SEE ALSO
+.Xr chpass 1 ,
+.Xr passwd 1 ,
+.Xr passwd 5 ,
+.Xr adduser 8 ,
+.Xr pwd_mkdb 8

+.Sh NAME
+.Nm watch
+.Nd snoop on another tty line
+.Sh SYNOPSIS
+.Nm
+.Op Fl cinotW
+.Op Fl f Ar snpdev
+.Op Ar tty
+.Sh DESCRIPTION
+.Nm Watch
+allows the user to examine all data coming through a specified tty
+using the
+.Xr snp 4
+device.
+If the
+.Xr snp 4
+device is not available,
+.Nm
+will attempt to load the module
+.Pq Nm snp .
+.Nm Watch
+writes to standard output.
+.Pp
+The options are as follows:
+.Bl -tag -width indent
+.It Fl c
+Reconnect on close.  If the tty observed by
+.Nm
+is closed,  automatically reattach to the same tty.
+If this option is not specified,
+.Nm
+will request a new tty if running in interactive mode or exit if running
+without a controlling tty.
+.It Fl f Ar snpdev
+If this option is specified,
+.Nm
+will use
+.Ar snpdev
+as the
+.Xr snp 4
+device.
+Without this option,
+.Nm
+will attempt to find the next available
+.Xr snp 4
+device.
+.It Fl i
+Force interactive mode.
+Interactive mode is a default if
+.Nm
+is started from a tty.
+If output is redirected to a file, interactive mode can still be requested
+by specifying this option.
+.It Fl n
+Disable the ability to switch the watched tty interactively.  This disables
+both change requests made with <control-X> as well as automatic prompting
+when the current tty is closed or overflows.  In all cases where a prompt
+would be displayed,
+.Nm
+will exit.  The reconnect flags are unaffected by
+this option.
+When this flag is used, <control-X> is passed through to the terminal.
+.It Fl o
+Reconnect on overflow.
+The behavior of
+.Nm
+if the observed tty overflows is similar to the behavior if the observed tty
+is closed.
+For more info see
+.Xr snp 4 .
+.It Fl t
+Print the date and time when observation of a given tty is started.
+.It Fl W
+Allow write access to observed tty.
+.It Ar tty
+Tty may be specified as an tty-style device, such as a pseudo tty device,
+a virtual console, or a serial line, etc.
+Names may be preceded by
+.Pa /dev/ .
+.El
+.Sh OPERATION
+While running in interactive mode, all user input is discarded except for:
+.Pp
+.Bl -tag -width "XXXX" -compact
+.It Sy "<control-G>"
+Exit
+.Nm .
+.It Sy "<control-W>"
+Clear screen.
+.It Sy "<control-X>"
+Change attached tty, unless this feature is disabled, in which case
+control-X is passed to the terminal as with other control characters.
+.El
+.Sh SEE ALSO
+.Xr pty 4 ,
+.Xr sio 4 ,
+.Xr snp 4 ,
+.Xr kldload 8
+.Sh BUGS
+No terminal emulation is performed.
+All user output is reproduced as-is.

+.Sh DESCRIPTION
+The
+.Nm
+command controls the operation of WaveLAN/IEEE wireless networking
+devices via the
+.Xr wi 4
+driver.
+Most of the parameters that can be changed relate to the
+IEEE 802.11 protocol which the WaveLAN implements.
+This includes
+the station name, whether the station is operating in ad-hoc (point
+to point) or BSS (service set) mode, and the network name of a service
+set to join (IBSS) if BSS mode is enabled.
+The
+.Nm
+command can also be used to view the current settings of these parameters
+and to dump out the values of the card's statistics counters.
+.Pp
+The
+.Ar iface
+argument given to
+.Nm
+should be the logical interface name associated with the WaveLAN/IEEE
+device
+.Li ( wi0 , wi1 ,
+etc.).
+If none is specified then
+.Dq Li wi0
+is used as default.
+.Sh OPTIONS
+The options are as follows:
+.Bl -tag -width indent
+.It Oo Fl i Oc Ar iface Op Fl o
+Display the current settings of the specified WaveLAN/IEEE interface.
+This retrieves the current card settings from the driver and prints them
+out.
+Using the additional
+.Fl o
+flag will cause
+.Nm
+to print out the statistics counters instead of the card settings.
+Encryption keys are only displayed if
+.Nm
+is run as root.
+.It Oo Fl i Oc Ar iface Fl t Ar tx_rate
+Set the transmit rate of the specified interface.
+The legal values
+for the transmit rate vary depending on whether the interface is a
+standard WaveLAN/IEEE or a WaveLAN/IEEE Turbo adapter.
+The standard
+NICs support a maximum transmit rate of 2Mbps while the turbo NICs
+support a maximum speed of 6Mbps.
+The following table shows the
+legal transmit rate settings and the corresponding transmit speeds:
+.Bl -column ".Em TX\ rate" ".Em NIC\ speed" -offset indent
+.Em "TX rate	NIC speed"
+.It Cm 1 Ta "Fixed Low (1Mbps)"
+.It Cm 2 Ta "Fixed Standard (2Mbps)"
+.It Cm 3 Ta "Auto Rate Select (High)"
+.It Cm 4 Ta "Fixed Medium (4Mbps)"
+.It Cm 5 Ta "Fixed High (6Mbps)"
+.It Cm 6 Ta "Auto Rate Select (Standard)"
+.It Cm 7 Ta "Auto Rate Select (Medium)"
+.El
+.Pp
+The standard NICs support only settings
+.Cm 1
+through
+.Cm 3 .
+Turbo NICs support all the above listed speed settings.
+The default driver setting is
+.Cm 3
+(auto rate select).
+.It Oo Fl i Oc Ar iface Fl n Ar network_name
+Set the name of the service set (IBSS) that this station wishes to
+join.
+The
+.Ar network_name
+can be any text string up to 30 characters in length.
+The default name
+is the string
+.Dq Li ANY
+which should allow the station to connect to the first
+available access point.
+The interface should be set for BSS mode using
+the
+.Fl p
+flag in order for this to work.
+.Pp
+Note: the WaveLAN manual indicates that an empty string will allow the
+host to connect to any access point, however I have also seen a reference
+in another driver which indicates that the
+.Dq Li ANY
+string works as well.
+.It Oo Fl i Oc Ar iface Fl s Ar station_name
+Sets the
+station name
+for the specified interface.
+The
+.Ar station_name
+is used for diagnostic purposes.
+The
+.Tn "Lucent WaveMANAGER"
+software can
+poll the names of remote hosts.
+.It Oo Fl i Oc Ar iface Fl c Cm 0 | 1
+Allow the station to create a service set (IBSS).
+Permitted values are
+.Cm 0
+(don't create IBSS) and
+.Cm 1
+(enable creation of IBSS).
+The default is
+.Cm 0 .
+.Pp
+Note: this option is provided for experimental purposes only: enabling
+the creation of an IBSS on a host system doesn't appear to actually work.
+.It Oo Fl i Oc Ar iface Fl q Ar SSID
+Specify the name of an IBSS (SSID) to create on a given interface.
+The
+.Ar SSID
+can be any text string up to 30 characters long.
+.Pp
+Note: this option is provided for experimental purposes only: enabling
+the creation of an IBSS on a host system doesn't appear to actually work.
+.It Oo Fl i Oc Ar iface Fl p Ar port_type
+Set the
+port type
+for a specified interface.
+The legal values for
+.Ar port_type
+are
+.Cm 1
+(BSS mode) and
+.Cm 3
+(ad-hoc) mode.
+In ad-hoc mode, the station can
+communicate directly with any other stations within direct radio range
+(provided that they are also operating in ad-hoc mode).
+In BSS mode,
+hosts must associate with a service set controlled by an access point,
+which relays traffic between end stations.
+The default setting is
+.Cm 3
+(ad-hoc mode).
+.It Oo Fl i Oc Ar iface Fl a Ar access_point_density
+Specify the
+access point density
+for a given interface.
+Legal values are
+.Cm 1
+(low),
+.Cm 2
+(medium) and
+.Cm 3
+(high).
+This setting influences some of the radio modem threshold settings.
+.It Oo Fl i Oc Ar iface Fl m Ar mac_address
+Set the station address for the specified interface.
+The
+.Ar mac_address
+is specified as a series of six hexadecimal values separated by colons,
+e.g.,
+.Dq Li 00:60:1d:12:34:56 .
+This programs the new address into the card
+and updates the interface as well.
+.It Oo Fl i Oc Ar iface Fl d Ar max_data_length
+Set the maximum receive and transmit frame size for a specified interface.
+The
+.Ar max_data_length
+can be any number from 350 to 2304.
+The default is 2304.
+.It Oo Fl i Oc Ar iface Fl e Cm 0 | 1
+Enable or disable WEP encryption.
+Permitted values are
+.Cm 0
+(encryption disabled) or
+.Cm 1
+(encryption enabled).
+Encryption is off by default.
+.Pp
+Both 128-bit and 64-bit WEP have been broken.
+See the
+.Sx BUGS
+section for details.
+.It Oo Fl i Oc Ar iface Fl k Ar key Op Fl v Cm 1 | 2 | 3 | 4
+Set WEP encryption keys.
+There are four default encryption keys
+that can be programmed.
+A specific key can be set using
+the
+.Fl v
+flag.
+If the
+.Fl v
+flag is not specified, the first key will be set.
+Encryption keys
+can either be normal text (i.e.\&
+.Dq Li hello )
+or a series of hexadecimal digits (i.e.\&
+.Dq Li 0x1234512345 ) .
+For
+WaveLAN Turbo Silver cards, the key is restricted to 40 bits, hence
+the key can be either a 5 character text string or 10 hex digits.
+For WaveLAN Turbo Gold cards, the key can also be 104 bits,
+which means the key can be specified as either a 13 character text
+string or 26 hex digits in addition to the formats supported by the
+Silver cards.
+.Pp
+Note: Both 128-bit and 64-bit WEP have been broken.
+See the
+.Sx BUGS
+section for details.
+.It Oo Fl i Oc Ar iface Fl T Cm 1 | 2 | 3 | 4
+Specify which of the four WEP encryption keys will be used to
+encrypt transmitted packets.
+.Pp
+Note: Both 128-bit and 64-bit WEP have been broken.
+See the
+.Sx BUGS
+section for details.
+.It Oo Fl i Oc Ar iface Fl r Ar RTS_threshold
+Set the RTS/CTS threshold for a given interface.
+This controls the
+number of bytes used for the RTS/CTS handshake boundary.
+The
+.Ar RTS_threshold
+can be any value between 0 and 2347.
+The default is 2347.
+.It Oo Fl i Oc Ar iface Fl f Ar frequency
+Set the radio frequency of a given interface.
+The
+.Ar frequency
+should be specified as a channel ID as shown in the table below.
+The
+list of available frequencies is dependent on radio regulations specified
+by regional authorities.
+Recognized regulatory authorities include
+the FCC (United States), ETSI (Europe), France and Japan.
+Frequencies
+in the table are specified in Mhz.

+If an illegal channel is specified, the
+NIC will revert to its default channel.
+For NICs sold in the United States
+and Europe, the default channel is
+.Cm 3 .
+For NICs sold in France, the default channel is
+.Cm 11 .
+For NICs sold in Japan, the default channel is
+.Cm 14 ,
+and it is the only available channel for pre-11Mbps NICs.
+Note that two stations must be set to the same channel in order to
+communicate.
+.It Oo Fl i Oc Ar iface Fl P Cm 0 | 1
+Enable or disable power management on a given interface.
+Enabling
+power management uses an alternating sleep/wake protocol to help
+conserve power on mobile stations, at the cost of some increased
+receive latency.
+Power management is off by default.
+Note that power
+management requires the cooperation of an access point in order to
+function; it is not functional in ad-hoc mode.
+Also, power management
+is only implemented in Lucent WavePOINT firmware version 2.03 or
+later, and in WaveLAN PCMCIA adapter firmware 2.00 or later.
+Older
+revisions will silently ignore the power management setting.
+Legal
+values for this parameter are
+.Cm 0
+(off) and
+.Cm 1
+(on).
+.It Oo Fl i Oc Ar iface Fl S Ar max_sleep_interval
+Specify the sleep interval to use when power management is enabled.
+The
+.Ar max_sleep_interval
+is specified in milliseconds.
+The default is 100.
+.It Oo Fl i Oc Ar iface Fl Z
+Clear the signal strength cache maintained internally by the
+.Xr wi 4
+driver.
+.It Oo Fl i Oc Ar iface Fl C
+Display the cached signal strength information maintained by the
+.Xr wi 4
+driver.
+The driver retains information about signal strength and
+noise level for packets received from different hosts.
+The signal
+strength and noise level values are displayed in units of dBms.
+The signal quality values is produced by subtracting the noise level
+from the signal strength (i.e. less noise and better signal yields
+better signal quality).

+.Sh BUGS
+The WEP encryption method has been broken so that third parties
+can recover the keys in use relatively quickly at distances that are
+surprising to most people.
+Do not rely on WEP for anything but the most basic, remedial security.
+IPSEC will give you a higher level of security and should be used
+whenever possible.
+Do not trust access points or wireless machines that connect through
+them as they can provide no assurance that the traffic is legitimate.
+MAC addresses can easily be forged and should therefore not be used as
+the only access control.
+.Pp
+The attack on WEP is a passive attack, requiring only the ability to
+sniff packets on the network.
+The passive attack can be launched at a distance larger, up to many
+miles, than one might otherwise expect given a specialized antenna
+used in point to point applications.
+The attacker can recover the keys from a 128-bit WEP network with only
+5,000,000 to 6,000,000 packets.
+While this may sound like a large number of packets, emperical
+evidence suggests that this amount of traffic is generated in a few
+hours on a partially loaded network.
+Once a key has been compromised, the only remedial action is to
+discontinue it and use a new key.
+.Pp
+See
+.Pa http://www.cs.rice.edu/~astubble/wep/wep_attack.html
+for details of the attack.
+.Pp
+If you must use WEP, you are strongly encouraged to pick keys whose
+bytes are random and not confined to ASCII characters.

+.Sh NAME
+.Nm wlconfig
+.Nd read/write wavelan config parameters
+.Sh SYNOPSIS
+.Nm
+.Ar ifname
+.Op Ar param value ...
+.Sh DESCRIPTION
+The
+.Nm
+command can be used to read and set parameters for the NCR/AT&T Wavelan
+radio LAN card.  Various parameters stored in the non-volatile Parameter
+Storage Area (PSA) on the card can be modified with this program, replacing
+the DOS-based
+.Nm instconf.exe
+program.  It can also be used to interrogate the optional signal
+strength cache which may have been compiled into the driver.
+.Pp
+The
+.Ar ifname
+parameter specifies the wavelan interface name (eg.
+.Pa wl0 ) .
+If no other arguments are supplied, the current contents of the PSA
+are interpreted and displayed.
+.Pp
+The
+.Ar param
+and
+.Ar value
+arguments can be used to change the value of several parameters.
+Any number of
+.Ar param value
+pairs may be supplied.
+.Bl -tag -width 15n -offset indent
+.It Va param
+.Va value
+.It irq
+IRQ value (used at next reset), may be one of 3,4,5,6,10,11,12,15.
+.It mac
+Local MAC value (ethernet address).
+.It macsel
+.Sq soft
+(as set by the
+.Sq mac
+parameter) or
+.Sq default
+(as set at the factory).
+.It nwid
+The NWID is a 2-byte parameter passed to the card's radio modem.
+NWIDs allow multiple logically discrete networks to operate
+independently whilst occupying the same airspace.
+Packets with a different NWID are simply ignored by the modem.
+In the hardware, NWIDs are stored long-term in non-volatile memory
+(called the PSA or programmable storage area), and are loaded by
+software into the radio modem when the driver is
+initialized.  This sets the default NWID loaded at startup.
+.It currnwid
+This sets the current operating NWID (but does not save it to the
+PSA).
+.It cache
+The driver may maintain a per interface fixed size cache of signal strength,
+silence, and quality levels, which are indexed by sender MAC addresses.
+Input packets are stored in the cache, and when received, the values
+stored in the radio modem are interrogated and stored.
+There are also two sysctl values (iponly and multicast only) which
+can be used for filtering out some input packets.  By default, the
+cache mechanism stores only non-unicast IP packets, but this can
+be changed with
+.Xr sysctl 8 .
+Each non-filtered
+input packet causes a cache update, hence one can monitor
+the antennae signal strength to a remote system.
+There are three commands that can be given as values:
+.Sq raw ,
+which prints out the raw signal strength data as found in the radio
+modem hardware value,
+.Sq scale ,
+which scales the raw hardware values to 0..100%, and
+.Sq zero
+which clears out the cache in case you want to store new samples.
+.El
+.Pp
+Note that if the IRQ on the Wavelan card is incorrect, the interface
+will be configured, but will not function.  The
+.Nm
+program should then be used to reconfigure the card to a sensible
+value.
+.Sh EXAMPLES
+Set the NWID to 0x1234:

+ * utility to read out and change various WAVELAN parameters.
+ * Currently supports NWID and IRQ values.
+ *
+ * The NWID is used by 2 or more wavelan controllers to determine
+ * if packets should be received or not.  It is a filter that
+ * is roughly analogous to the "channel" setting with a garage
+ * door controller.  Two companies side by side with wavelan devices
+ * that could actually hear each other can use different NWIDs
+ * and ignore packets.  In truth however, the air space is shared, 
+ * and the NWID is a virtual filter.
+ *
+ * In the current set of wavelan drivers, ioctls changed only
+ * the runtime radio modem registers which act in a manner analogous
+ * to an ethernet transceiver.  The ioctls do not change the 
+ * stored nvram PSA (or parameter storage area).  At boot, the PSA
+ * values are stored in the radio modem.   Thus when the
+ * system reboots it will restore the wavelan NWID to the value
+ * stored in the PSA.  The NCR/ATT dos utilities must be used to
+ * change the initial NWID values in the PSA.  The wlconfig utility
+ * may be used to set a different NWID at runtime; this is only
+ * permitted while the interface is up and running.
+ *
+ * By contrast, the IRQ value can only be changed while the 
+ * Wavelan card is down and unconfigured, and it will remain
+ * disabled after an IRQ change until reboot.

+Installation Notes for X-10 software
+Eugene W. Stark (stark@cs.sunysb.edu)
+October 30, 1993
+(latest update May 29, 1997)
+
+The TW523 is a carrier-current modem for home control/automation purposes.
+It is made by:
+
+	X-10 Inc.
+	185A LeGrand Ave.
+	Northvale, NJ 07647
+	USA
+	(201) 784-9700 or 1-800-526-0027
+
+ 	X-10 Home Controls Inc.
+	1200 Aerowood Drive, Unit 20
+	Mississauga, Ontario
+	(416) 624-4446 or 1-800-387-3346
+
+The TW523 is designed for communications using the X-10 protocol,
+which is compatible with a number of home control systems, including
+Radio Shack "Plug 'n Power(tm)" and Stanley "Lightmaker(tm)."
+I bought my TW523 from:
+
+	Home Control Concepts
+	9353-C Activity Road
+	San Diego, CA 92126
+	(619) 693-8887
+
+They supplied me with the TW523 (which has an RJ-11 four-wire modular
+telephone connector), a modular cable, an RJ-11 to DB-25 connector with
+internal wiring, documentation from X-10 on the TW523 (very good),
+an instruction manual by Home Control Concepts (not very informative),
+and a floppy disk containing binary object code of some demonstration/test
+programs and of a C function library suitable for controlling the TW523
+by an IBM PC under MS-DOS (not useful to me other than to verify that
+the unit worked).   I suggest saving money and buying the bare TW523
+rather than the TW523 development kit (what I bought), because if you
+are running FreeBSD you don't really care about the DOS binaries.
+For details on the X-10 protocol itself, refer to the documentation from
+X-10 Inc.
+
+The interface to the TW-523 consists of four wires on the RJ-11 connector,
+which are jumpered to somewhat more wires on the DB-25 connector, which
+in turn is intended to plug into the PC parallel printer port.  I dismantled
+the DB-25 connector to find out what they had done:
+
+	Signal		RJ-11 pin	DB-25 pin(s)	Parallel Port
+	Transmit TX	  4 (Y)		2, 4, 6, 8	Data out
+	Receive RX	  3 (G)		10, 14		-ACK, -AutoFeed
+	Common		  2 (R)		25		Common
+	Zero crossing	  1 (B)		17 or 12	-Select or +PaperEnd
+
+NOTE: In the original cable I have (which I am still using, May, 1997)
+the Zero crossing signal goes to pin 17 (-Select) on the parallel port.
+In retrospect, this doesn't make a whole lot of sense, given that the
+-Select signal propagates the other direction.  Indeed, some people have
+reported problems with this, and have had success using pin 12 (+PaperEnd)
+instead.  This driver searches for the zero crossing signal on either
+pin 17 or pin 12, so it should work with either cable configuration.
+My suggestion would be to start by making the cable so that the zero
+crossing signal goes to pin 12 on the parallel port.
+
+I use the TW-523 and this software in the USA with 120V/60Hz power.
+Phil Sampson (vk2jnt@gw.vk2jnt.ampr.org OR sampson@gidday.enet.dec.com)
+in Australia has reported success in using a TW-7223 (a local version
+of the TW-523) and Tandy modules with this software under 240V/50Hz power.
+For reasons explained in the comments in the driver, it will probably not
+work if you have three-phase power, but this is usually not the case for
+normal residences and offices.
+
+
+1.  Installing the TW523 Device Driver
+
+I assume that you are running FreeBSD.  If you are running some other
+system, you are more or less on your own, though I can try to help if you
+have problems.
+
+Check the configuration parameters at the beginning of the file
+
+	/sys/i386/isa/tw.c
+
+Probably the only thing you might need to change is to change the
+definition of HALFCYCLE from 8333 to 10000 if you are using 50Hz power.
+The driver assumes that the TW523 device is connected to a parallel port.
+See the comments near the beginning of the file to find out where to
+get a TW523 if you don't have one, and how to make a cable for it to
+connect to your parallel port.
+
+Add a line like the following
+
+	device		tw0	at isa? port 0x278 tty irq 5
+
+to /sys/i386/conf/YOURSYSTEM, but make sure to change the I/O port and
+interrupt to match your hardware configuration.
+
+Cd to /sys/i386/conf and do "config YOURSYSTEM".
+Cd to /sys/compile/YOURSYSTEM and do "make depend", then "make".
+(If you have any troubles, I suggest starting fresh by doing a full
+"make clean; make depend; make".)  Assuming the make works correctly, do
+
+	make install
+
+(Take the usual precautions by saving a known working kernel until you
+verify that the new kernel actually boots.)
+
+Reboot the system.  You should see a line indicating that the TW523 has
+been configured as the system comes up.  If you see this line, then probably
+everything is going to work OK, because the TW523 will only get configured
+if the driver is able to sync to the power line.  If the TW523 is not plugged
+in, or the driver is not getting sync for some reason, then you won't see
+any message on bootup.
+
+NOTE:  I have received a report that some multi IDE/SIO/PARALLEL cards
+"cheat" and use TTL outputs rather than pullup open collector outputs,
+and this can mess up the scheme by which sync gets to the driver.
+If you are having trouble getting the driver to work, you might want to
+look into this possibility.
+
+In directory /dev, execute the command
+
+	MAKEDEV tw0
+
+
+2.  Installing the X-10 Daemon
+
+The X-10 daemon "xtend" is integrated in to the FreeBSD "/etc/sysconfig"
+system configuration file.  To enable the daemon, simply edit that file,
+find the "xtend" line, change it to read as below.
+
+	# Set to YES if you want to run the X-10 power controller daemon
+	xtend=YES
+
+This will cause the X-10 daemon to be invoked automatically when you boot
+the system.  To test the installation, you can either reboot now, or
+you can just run "xtend" by hand.  The daemon should start up, and it should
+create files in /var/spool/xten.  Check the file /var/spool/xten/Log to
+make sure that the daemon started up without any errors.
+
+Now you are ready to start trying X-10 commands.  Try doing
+
+	xten A 1 Off
+	xten A 1 On 1 Dim:10
+
+etc.  The "xten" program expects a house code as its first argument, then
+a series of key codes, which are either unit names ("1" through "16") or
+else are command names.  You can find the list of command names by looking
+at the table in the file "xten.c".  Each key code can optionally be followed
+by a colon : then a number specifying the number of times that command is
+to be transmitted without gaps between packets.  The default is 2, and this
+is the normal case, but some commands like Bright and Dim are designed to
+be transmitted with counts other than 2.  See the X-10 documentation for
+more detail.
+
+The "xten" program works by connecting to "xtend" through a socket, and
+asking that the X-10 codes be transmitted over the TW523.  All activity
+on the TW523 is logged by the daemon in /var/spool/xten/Log.  The daemon
+also attempts to track the state of all devices.  (Of course, most X-10
+devices do not transmit when they are operated manually, so if somebody
+operates a device manually there is no way the X-10 daemon will know
+about it.) 
+
+3. Low-level Programming of the TW523 Driver
+
+Normally, you would never operate the TW523 directly, rather you would
+use the shell command "xten" or you would connect to "xtend" through its
+socket.  However, if you don't want to run "xtend", you can manipulate
+the TW523 directly through the device /dev/tw0.  Have a look at the
+xtend code for a programming example.
+
+The driver supports read(), write(), and select() system calls.
+The driver allows multiple processes to read and write simultaneously,
+but there is probably not much sense in having more than one reader or more
+than one writer at a time, and in fact there may currently be a race
+condition in the driver if two processes try to transmit simultaneously
+(due to unsynchronized access to the sc_pkt structure in tw_sc).
+
+Transmission is done by calling write() to send three byte packets of data.
+The first byte contains a four bit house code (0=A to 15=P).  The second byte
+contains five bit unit/key code (0=unit 1 to 15=unit 16, 16=All Units Off
+to 31 = Status Request).  The third byte specifies the number of times the
+packet is to be transmitted without any gaps between successive transmissions.
+Normally this is 2, as per the X-10 documentation, but sometimes (e.g. for
+bright and dim codes) it can be another value.  Each call to write can specify
+an arbitrary number of data bytes, but at most one packet will actually be
+processed in any call.  Any incomplete packet is buffered until a subsequent
+call to write() provides data to complete it.  Successive calls to write()
+leave a three-cycle gap between transmissions, per the X-10 documentation.
+The driver transmits each bit only once per half cycle, not three times as
+the X-10 documentation states, because the TW523 only provides sync on
+each power line zero crossing.  So, the driver will probably not work
+properly if you have three-phase service.  Most residences use a two-wire
+system, for which the driver does work.
+
+Reception is done using read().  The driver produces a series of three
+character packets.  In each packet, the first character consists of flags,
+the second character is a four bit house code (0-15), and the third character
+is a five bit key/function code (0-31).  The flags are the following:
+
+#define TW_RCV_LOCAL	1  /* The packet arrived during a local transmission */
+#define TW_RCV_ERROR	2  /* An invalid/corrupted packet was received */
+
+The select() system call can be used in the usual way to determine if there
+is data ready for reading.

+
+I have just verified that /dev/tw works on 2.1.0-RELEASE.  I can
+send and receive x10 commands via my x10 daemon and X11 based tools.
+
+I used a "cross-over" cable between tw523 and db-25 connector:
+

+
+Be sure that the tw523 is NOWHERE NEAR a surge protector.  I have seen
+x-10 devices fail to work when plugged in NEXT to a surge protector!
+
+
+I placed the tw option before the lpt entries in my config file: 
+
+device          tw0     at isa? port 0x378 tty irq 7
+device          lpt0    at isa? port? tty irq 7
+
+from dmesg I get:
+
+Dec  9 19:11:59 ilsa /kernel: tw0 at 0x378-0x37f irq 7 on isa
+Dec  9 19:11:59 ilsa /kernel: lpt0 not probed due to I/O address conflict with 
+tw0 at 0x378
+
+Once I have opened /dev/tw with my daemon I get messages 
+ (pressing UNIT J, key 16):
+
+Dec  9 20:18:26 ilsa /kernel: TWRCV: valid packet: (22, 1f8) J 16
+Dec  9 20:18:26 ilsa /kernel: TWRCV: valid packet: (22, 1f8) J 16
+
+These messages from the driver should be dis-abled once you get it working,
+you'll fill up the var partition with a lot of useless garbage otherwise!

+
+Hi,
+
+I now more or less understand the set of problems concerning cabling
+for using /dev/tw and a tw523.  Summary:
+
+
+ 1: modular cables come in 2 flavors:
+
+|||||----------|||||		<- "phone" cable
+ \                /
+
+                  \
+|||||----------|||||		<- "data" cable
+ \
+
+ we need to be able to clearly differentiate the two.  I suggest we
+ standardize on using "phone" cables only.
+
+
+ 2: modular db25 connectors ARE NOT CONSISTANT in their color code
+    scheme, EVEN within the same BRAND!
+
+ we can't describe the connection in terms of cable/connector wire color.
+ we must clearly explain the consequences of mis-connection: 
+ POSSIBLE damage to (but NOT limited to) the parallel port and/or tw523.
+
+
+ 3: not all parallel ports have pullups on their status inputs.  I found
+    2 different port boards in my junk box without pullups on paper-out.
+    As is, these boards failed to work, ie the probe routine failed.
+    By adding 10K pullup resistors (to +5v) to both ACK and paper-out
+    (pins 10 & 12) I was able to make these boards work: probe succeeds,
+    transmit and receive work reliably.
+
+ we must describe a test to determine if a parallel port will work as is.
+ perhaps something like:
+
+--------------------------------------------------------------------------
+Not a parallel ports will work with the connector described in this paper.
+To test your port for usability you should take the following measurements
+with a voltmeter.  The computer must be powered-up, and preferably in
+a safe state for tinkering, such as halted in a startup menu. Nothing
+should be attached to the parallel ports, except perhaps an extension
+cable for testing convenience.
+
+ 1: measure the voltage between pins 10 & 25 (GND) of the parallel port.
+
+ 2: measure the voltage between pins 12 & 25 (GND) of the parallel port.
+
+If both of these measurements have a value of >= 4.0 volts your port
+should work as is.  If either is below 4.0 volts (typically less than
+1.0 volt) your port will NOT WORK RELIABLY as is.  It can be made to 
+work by adding 10k ohm pull-up resistors to either line that is below
+the minimum 4.0 volts.  This is an ADVANCED TECHNIQUE that should NOT
+be attempted by anyone without some hardware construction experience.
+
+Assuming that you do feel competant to make these modifications it is
+easiest to tack 10k resistors on the bottom side of the port board
+from each of pins 10 & 12 of the parallel port connector to a source
+of +5 volts.  This will probably be the power pin of one of the ICs.
+CAUTION: there may also be +-12 volts on a port board supplying some
+of the ICs.  If your port is on your motherboard it would probably be
+best to obtain an external port card, and disable/re-address the 1st
+parallel port.

+.Oo
+.Op Ar house
+.Ar key Ns Op : Ns Ar cnt
+.Ar ...
+.Oc
+.Sh DESCRIPTION
+The
+.Nm
+utility is a command-line interface to the X-10 daemon.
+When invoked with a one-letter house code (A-P) and a series of key/unit
+codes as arguments, it requests the X-10 daemon to transmit a corresponding
+series of X-10 packets.  The X-10 daemon makes its best effort to ensure
+that the packets are all transmitted correctly, though in general it is
+not possible to tell whether the commands were actually received and
+executed by the remote X-10 devices.
+.Pp
+When invoked with the single argument
+.Fl "" ,
+.Nm
+enters an interactive mode in which a line is repeatedly read from the
+standard input, sent to the X-10 daemon, and the one-line response from
+the daemon printed on the standard output.
+.Sh OPTIONS
+The
+.Ar house
+argument is a one-letter house code in the range A-P.
+All the X-10 requests generated will refer to this house code.
+Each
+.Ar key
+is either a numeric unit code in the range 1-16, or else
+is a string that specifies an X-10 function.  The possible
+function code strings are:
+.Bl -diag
+.It AllUnitsOff
+.It AllLightsOn
+.It On
+.It Off
+.It Dim
+.It Bright
+.It AllLightsOff
+.It ExtendedCode
+.It HailRequest
+.It HailAcknowledge
+.It PreSetDim0
+.It PreSetDim1
+.It ExtendedData
+.It StatusOn
+.It StatusOff
+.It StatusRequest
+.El
+.Pp
+Each
+.Ar key
+may be followed by an optional numeric
+.Ar cnt ,
+which specifies the number of packets that are to be sent with that
+key code without gaps.  If this argument is omitted, two packets
+are transmitted.  The ability to specify numbers of packets other than
+two is used by the X-10
+.Em Dim
+and
+.Em Bright
+commands.

+.Op Fl s
+.Op Fl f
+.Op Fl i Ar inputfile
+.Op Fl o Ar outputfile

+.Ar dbname
+.Sh DESCRIPTION
+.Nm Yp_mkdb
+creates
+.Xr db 3
+style databases for use with
+.Fx Ns 's
+NIS server.
+.Nm Yp_mkdb
+reads data from
+.Ar inputfile ,
+and writes it to
+.Ar dbname
+in
+.Xr db 3
+format (using the hash table method).
+The input should be in 'key data' format, which is to say
+two fields of
+.Tn ASCII
+data separated by white space.
+The first field
+is assumed to be the key, and everything else is assumed to be
+the data.
+These databases are typically stored in
+.Pa /var/yp/[domainname]
+where
+.Ar domainname
+is the name of the NIS domain being served.
+.Nm Yp_mkdb
+is usually invoked by
+.Pa /var/yp/Makefile .
+.Nm Yp_mkdb
+can also be used to dump an NIS database file so that its
+contents can be examined.
+For security reasons, all databases that
+.Nm
+creates are readable and writable by owner only (and usually the
+owner is root).
+.Pp
+The following options are available:
+.Bl -tag -width indent
+.It Fl c
+Cause
+.Nm
+to send a YPPROC_CLEAR request to
+.Xr ypserv 8
+on the local host.
+This signal tells the server to close any open
+database descriptors and flush out its database cache.
+If used alone,
+this flag signals the server and does nothing else.
+If used as part
+of a database creation command,
+.Nm
+will send the signal only after the new database has been successfully
+created.
+.It Fl b
+Cause
+.Nm
+to add a special entry to the database with a key of
+.Em YP_INTERDOMAIN
+and an empty data field.
+If this key is present in a map, it alters the
+behavior of the 'match' procedure in
+.Xr ypserv 8
+slightly.
+If a match query fails (because the server couldn't find
+a record that matched the supplied key), and the
+.Em YP_INTERDOMAIN
+key exists within the queried map,
+.Xr ypserv 8
+will try to match the entry again using a DNS lookup.
+Note that this
+special behavior only applies to the
+.Em hosts
+maps.
+Using the
+.Fl b
+flag for other maps has no effect.
+.It Fl s
+This flag is used to add a special entry to the database with a key of
+.Em YP_SECURE
+and an empty data field.
+If this key is present in a map,
+.Xr ypserv 8
+will deny access to the map to any client that is not using a
+reserved port for its query.
+This is used mainly for the
+.Em master.passwd
+maps, which should be restricted to privileged access only.
+.It Fl f
+This flag is used to turn on filtering of lines in the source file
+input that start with ``+'' or ``-'' characters.
+These characters
+have special meaning for the
+.Pa group ,
+.Pa passwd
+and
+.Pa master.passwd
+maps and hence should not be allowed to appear in them as the first
+character of a key or datum.
+If the
+.Fl f
+flag is used,
+.Nm
+will reject any source line that starts with a ``+'' or ``-''
+character and issue a warning message displaying the line that
+was dropped.
+.It Fl u Ar dbname
+Dump (or 'unwind') an NIS database.
+This option can be used to
+inspect the contents of an existing NIS database.
+.It Fl i Ar inputfile
+When generating an NIS map, encode
+.Ar inputfile
+as a special entry in the database with a key of
+.Em YP_INPUT_FILE .
+.It Fl o Ar outputfile
+When generating an NIS map, encode
+.Ar outputfile
+as a special entry in the database with a key of
+.Em YP_OUTPUT_FILE .
+.It Fl d Ar domainname
+When generating an NIS map, encode
+.Ar domainname
+as a special entry in the database with a key of
+.Em YP_DOMAIN_NAME .
+.It Fl m Ar mastername
+When generating an NIS map, encode
+.Ar mastername
+as a special entry in the database with a key of
+.Em YP_MASTER_NAME .
+This entry in the database is frequently used by various NIS utilities
+to determine the name of an NIS master server for a domain.
+By default,
+.Nm
+assumes that the local host is the NIS master; the
+.Fl m
+option is used to override this default.

+.Nm ypbind
+.Nd "NIS domain binding daemon"
+.Sh SYNOPSIS
+.Nm
+.Op Fl ypset
+.Op Fl ypsetme
+.Op Fl s
+.Op Fl m
+.Oo
+.Fl S
+.Sm off
+.Ar domainname , server1 , server2 , ...
+.Sm on
+.Oc
+.Sh DESCRIPTION
+.Nm Ypbind
+is the process that maintains NIS binding information.
+At startup,
+it searches for an NIS server responsible for serving the system's
+default domain (as set by the
+.Xr domainname 1
+command) using network broadcasts.
+Once it receives a reply,
+it will store the address of the server and other
+information in a special file located in
+.Pa /var/yp/binding .
+The NIS routines in the standard C library can then use this file
+when processing NIS requests.
+There may be several such files
+since it is possible for an NIS client to be bound to more than
+one domain.
+.Pp
+After a binding has been established,
+.Nm
+will send DOMAIN_NONACK requests to the NIS server at one minute
+intervals.
+If it fails to receive a reply to one of these requests,
+.Nm
+assumes that the server is no longer running and resumes its network
+broadcasts until another binding is established.
+.Nm Ypbind
+will also log warning messages using the
+.Xr syslog 3
+facility each time it detects that a server has stopped responding,
+as well as when it has bound to a new server.
+.Pp
+The following options are available:
+.Bl -tag -width indent
+.It Fl ypset
+It is possible to force
+.Nm
+to bind to a particular NIS server host for a given domain by using the
+.Xr ypset 8
+command.
+However,
+.Nm
+refuses YPBINDPROC_SETDOM requests by default since it has no way of
+knowing exactly who is sending them.
+Using the
+.Fl ypset
+flag causes
+.Nm
+to accept YPBINDPROC_SETDOM requests from any host.
+This option should only
+be used for diagnostic purposes and only for limited periods since allowing
+arbitrary users to reset the binding of an NIS client poses a severe
+security risk.
+.It Fl ypsetme
+This is similar to the
+.Fl ypset
+flag, except that it only permits YPBINDPROC_SETDOM requests to be processed
+if they originated from the local host.
+.It Fl s
+Cause
+.Nm
+to run in secure mode: it will refuse to bind to any NIS server
+that is not running as root (i.e. that is not using privileged
+TCP ports).
+.It Fl S Xo
+.Sm off
+.Ar domainname , server1 , server2 , server3 , ...
+.Sm on
+.Xc
+Allow the system administrator to lock
+.Nm
+to a particular
+domain and group of NIS servers.
+Up to ten servers can be specified.
+There must not be any spaces between the commas in the domain/server
+specification.
+This option is used to insure that the system binds
+only to one domain and only to one of the specified servers, which
+is useful for systems that are both NIS servers and NIS
+clients: it provides a way to restrict what machines the system can
+bind to without the need for specifying the
+.Fl ypset
+or
+.Fl ypsetme
+options, which are often considered to be security holes.
+The specified
+servers must have valid entries in the local
+.Pa /etc/hosts
+file. IP addresses may be specified in place of hostnames.
+If
+.Nm
+can't make sense ouf of the arguments, it will ignore
+the
+.Fl S
+flag and continue running normally.
+.Pp
+Note that
+.Nm
+will consider the domainname specified with the
+.Fl S
+flag to be the system default domain.
+.It Fl m
+Cause
+.Nm
+to use a 'many-cast' rather than a broadcast for choosing a server
+from the restricted mode server list.
+In many-cast mode,
+.Nm
+will transmit directly to the YPPROC_DOMAIN_NONACK procedure of the
+servers specified in the restricted list and bind to the server that
+responds the fastest.
+This mode of operation is useful for NIS clients on remote subnets
+where no local NIS servers are available.
+The
+.Fl m
+flag can only be used in conjunction with the
+.Fl S
+flag above (if used without the
+.Fl S
+flag, it has no effect).
+.El
+.Sh NOTES
+The
+.Nm
+program will not make continuous attempts to keep secondary domains bound.
+If a server for a secondary domain fails to respond to a ping,
+.Nm
+will broadcast for a new server only once before giving up.
+If a
+client program attempts to reference the unbound domain,
+.Nm
+will try broadcasting again.
+By contrast,
+.Nm
+will automatically maintain a binding for the default domain whether
+client programs reference it ot not.
+.Sh FILES

+.Sh NAME
+.Nm yppush
+.Nd "force propagation of updated NIS databases"
+.Sh SYNOPSIS
+.Nm
+.Op Fl d Ar domain
+.Op Fl t Ar timeout
+.Op Fl j Ar #parallel jobs
+.Op Fl h Ar host
+.Op Fl p Ar path
+.Op Fl v
+.Ar mapname
+.Sh DESCRIPTION
+.Nm Yppush
+distributes updated NIS databases (or
+.Pa maps )
+from an NIS master server to NIS slave servers within an NIS
+domain.
+It is normally only run on the NIS master by
+.Pa /var/yp/Makefile
+whenever any of the NIS maps are updated.
+Note that
+.Pa /var/yp/Makefile
+does not invoke
+.Nm
+by default: the
+.Dq Li NOPUSH=True
+entry in the Makefile must first be commented out
+(the default
+.Fx
+configuration assumes a small network with only
+a single NIS server; in such a configuration,
+.Nm
+is not needed).
+.Pp
+By default,
+.Nm
+determines the names of the slave servers for a domain by searching the
+.Pa ypservers
+map. A destination host (or a list of hosts) can also be manually
+specified on the command line.
+Once it has a complete list of slave servers, it sends a 'map transfer'
+request to each slave, which in turn reads a copy of the map from
+the master NIS server using
+.Xr ypxfr 8 .
+Included within each request is the name of the map to be copied
+and some special information required by
+.Xr ypxfr 8
+to successfully 'callback' to
+.Nm
+and carry out the transfer.
+Any error messages
+.Nm
+receives from
+.Xr ypxfr 8
+via callback will be printed to stderr.
+.Pp
+The following options are available:
+.Bl -tag -width indent
+.It Fl d Ar domain
+Specify a particular domain.
+The NIS domain of
+the local host system is used by default.
+If the local host's domain
+name is not set, the domain name must be specified with this flag.
+.It Fl t Ar timeout
+Specify a timeout value in seconds.
+This timeout
+controls how long
+.Nm
+will wait for a response from a slave server before sending a
+map transfer request to the next slave server in its list.
+.It Fl j Ar #parallel jobs
+.Nm Yppush
+normally performs transfers serially, meaning that it will
+send a map transfer request to one slave server and then wait for
+it to respond before moving on to the next slave server.
+In environments
+with many slaves, it is more efficient to initiate several map transfers
+at once so that the transfers can take place in parallel.
+The
+.Fl j
+flag is used to specify the desired number of parallel jobs:
+.Nm
+will initiate the specified number of transfers immediately and
+listen for responses.
+If the number of specified parallel jobs is
+less than the number of slave servers,
+.Nm
+will initiate only the number of specified jobs and then wait
+for some of them to finish before starting any more.
+.Pp
+Note that
+.Nm
+handles callbacks asynchronously, which means that it will collect
+and display the callback information received from
+.Xr ypxfr 8
+as soon as it arrives, even it arrives before all of the map
+transfer requests have been sent.
+.It Fl h Ar host
+Can be used to transfer a map to a user-specified machine or
+group of machines instead of the list of servers contained in
+the
+.Pa ypservers
+map. A list of hosts can be specified by using multiple
+instances of the
+.Fl h
+flag.
+.It Fl p Ar path
+By default,
+.Nm
+expects all the local NIS maps to be stored under
+.Pa /var/yp .
+The
+.Fl p
+flag can be used to specify an alternate path in the event that
+the system administrator decides to store the NIS maps somewhere else.
+.It Fl v
+Verbose mode: causes
+.Nm
+to print debugging messages as it runs.
+Specifying this flag twice
+makes
+.Nm
+even more verbose.
+.El
+.Sh FILES
+.Bl -tag -width Pa -compact
+.It Pa /var/yp/[domainname]/ypservers
+the NIS ypservers map containing the names of all servers in
+a particular NIS domain
+.El
+.Sh SEE ALSO
+.Xr yp 8 ,
+.Xr ypserv 8 ,
+.Xr ypxfr 8
+.Sh BUGS
+The mechanism for transferring NIS maps in NIS v1 is different
+than that in NIS version 2. This version of
+.Nm
+has support for transferring maps to NIS v2 systems only.

+ * Access control functions.
+ *
+ * yp_access() checks the mapname and client host address and watches for
+ * the following things:
+ *
+ * - If the client is referencing one of the master.passwd.* maps, it must
+ *   be using a privileged port to make its RPC to us. If it is, then we can
+ *   assume that the caller is root and allow the RPC to succeed. If it
+ *   isn't access is denied.
+ *
+ * - The client's IP address is checked against the securenets rules.
+ *   There are two kinds of securenets support: the built-in support,
+ *   which is very simple and depends on the presence of a
+ *   /var/yp/securenets file, and tcp-wrapper support, which requires
+ *   Wietse Venema's libwrap.a and tcpd.h. (Since the tcp-wrapper
+ *   package does not ship with FreeBSD, we use the built-in support
+ *   by default. Users can recompile the server with the tcp-wrapper library
+ *   if they already have it installed and want to use hosts.allow and
+ *   hosts.deny to control access instead of having a separate securenets
+ *   file.)
+ *
+ *   If no /var/yp/securenets file is present, the host access checks
+ *   are bypassed and all hosts are allowed to connect.
+ *
+ * The yp_validdomain() function checks the domain specified by the caller
+ * to make sure it's actually served by this server. This is more a sanity
+ * check than an a security check, but this seems to be the best place for
+ * it.

+.Sh NAME
+.Nm ypinit
+.Nd build and install NIS databases
+.Sh SYNOPSIS
+.Nm
+.Fl m
+.Op Ar domainname
+.Nm
+.Fl s
+.Ar master_server
+.Op Ar domainname
+.Nm
+.Fl u
+.Op Ar domainname
+.Sh DESCRIPTION
+The
+.Nm
+script sets up databases on a Network Information Service (NIS)
+master or slave server.
+.Pp
+On a master server,
+.Nm
+creates the
+.Pa /var/yp/$DOMAINNAME
+directory, the
+.Pa /var/yp/ypservers
+file, and calls
+.Pa /var/yp/Makefile
+to create and populate an initial set of NIS maps.
+The maps are
+created from local source files using the
+.Xr yp_mkdb 8
+command.
+The script will prompt the user for a list of servers
+that support the specified domain; this list is used to populate
+the ypservers map.
+.Pp
+On a slave server,
+.Nm
+creates the
+.Pa /var/yp/$DOMAINNAME ,
+populates it with copies of the NIS maps from the master.
+The maps
+are obtained from the master using the
+.Xr ypxfr 8
+command.
+The
+.Nm
+script obtains the list of maps to transfer in one of two ways: if
+the system is configured as an NIS client and is bound to the master
+server,
+.Nm
+is able to use the
+.Xr ypwhich 1
+command to obtain a list of maps exported by the master server.
+If the system is not configured as a client of the NIS master,
+.Nm
+uses a hardcoded list of maps, some of which may or may not actually
+exist on the master.
+The system administrator can edit the script and
+modify the map list if necessary.
+Otherwise, indivudual maps can
+be transfered manually from the master using
+.Xr ypxfr 8 .
+.Sh OPTIONS
+.Nm Ypinit
+supports the following options:
+.Bl -tag -width indent
+.It Fl m Op Ar domainname
+Set up a master server.
+By default, the script sets up a server for
+the system default domain.
+The user can override this default by specifying
+.Ar domainname
+explicitly.
+Maps are constructed from scratch using local files as templates using
+the
+.Xr yp_mkdb 8
+command.
+.It Fl s Ar master_server Op Ar domainname
+Set up a slave server using
+.Ar master_name
+as the master.
+Maps are copied from
+.Ar master_server
+to the slave using
+.Xr ypxfr 8 .
+By default, the script sets up a server for
+the system default domain.
+The user can override this default by specifying
+.Ar domainname
+explicitly.
+.It Fl u Op Ar domainname
+Update the ypservers map on the master server.
+When a new slave
+server is added to a domain, its hostname must be added to the
+ypservers map so that
+.Xr yppush 8
+can propagate updates on the master to all of the slaves.

+.Sh NAME
+.Nm ypserv
+.Nd NIS database server
+.Sh SYNOPSIS
+.Nm
+.Op Fl n
+.Op Fl d
+.Op Fl p Ar path
+.Sh DESCRIPTION
+.Tn NIS
+is an RPC-based service designed to allow a number of UNIX-based
+machines to share a common set of configuration files.
+Rather than
+requiring a system administrator to update several copies of files
+such as
+.Pa /etc/hosts ,
+.Pa /etc/passwd
+and
+.Pa /etc/group ,
+which tend to require frequent changes in most environments,
+.Tn NIS
+allows groups of computers to share one set of data which can be
+updated from a single location.
+.Pp
+The
+.Nm
+program is the server that distributes
+.Tn NIS
+databases to client systems within an
+.Tn NIS
+.Em domain .
+Each client in an
+.Tn NIS
+domain must have its domainname set to
+one of the domains served by
+.Nm
+using the
+.Xr domainname 1
+command.
+The clients must also run
+.Xr ypbind 8
+in order to attach to a particular server, since it is possible to
+have several servers within a single
+.Tn NIS
+domain.
+.Pp
+The databases distributed by
+.Nm
+are stored in
+.Pa /var/yp/[domainname]
+where
+.Pa domainname
+is the name of the domain being served.
+There can be several
+such directories with different domainnames, and you need only one
+.Nm
+daemon to handle them all.
+.Pp
+The databases, or
+.Pa maps
+as they are often called,
+are created by
+.Pa /var/yp/Makefile
+using several system files as source.
+The database files are in
+.Xr db 3
+format to help speed retrieval when there are many records involved.
+In
+.Fx ,
+the maps are always readable and writable only by root for security
+reasons.
+Technically this is only necessary for the password
+maps, but since the data in the other maps can be found in
+other world-readable files anyway, it doesn't hurt and it's considered
+good general practice.
+.Pp
+The
+.Nm
+program is started by
+.Pa /etc/rc.network
+if it has been enabled in
+.Pa /etc/rc.conf .
+.Sh SPECIAL FEATURES
+There are some problems associated with distributing a
+.Fx
+password
+database via
+.Tn NIS Ns :
+.Fx
+normally only stores encrypted passwords
+in
+.Pa /etc/master.passwd ,
+which is readable and writable only by root.
+By turning this file
+into an
+.Tn NIS
+map, this security feature would be completely defeated.
+.Pp
+To make up for this, the
+.Fx
+version of
+.Nm
+handles the
+.Pa master.passwd.byname
+and
+.Pa master.passwd.byuid
+maps in a special way.
+When the server receives a request to access
+either of these two maps, it will check the TCP port from which the
+request originated and return an error if the port number is greater
+than 1023.
+Since only the superuser is allowed to bind to TCP ports
+with values less than 1024, the server can use this test to determine
+whether or not the access request came from a privileged user.
+Any requests made by non-privileged users are therefore rejected.
+.Pp
+Furthermore, the
+.Xr getpwent 3
+routines in the
+.Fx
+standard C library will only attempt to retrieve
+data from the
+.Pa master.passwd.byname
+and
+.Pa master.passwd.byuid
+maps for the superuser: if a normal user calls any of these functions,
+the standard
+.Pa passwd.byname
+and
+.Pa passwd.byuid
+maps will be accessed instead.
+The latter two maps are constructed by
+.Pa /var/yp/Makefile
+by parsing the
+.Pa master.passwd
+file and stripping out the password fields, and are therefore
+safe to pass on to unprivileged users.
+In this way, the shadow password
+aspect of the protected
+.Pa master.passwd
+database is maintained through
+.Tn NIS .
+.Sh NOTES
+.Ss Setting Up Master and Slave Servers
+.Xr ypinit 8
+is a convenient script that will help setup master and slave
+.Tn NIS
+servers.
+.Ss Limitations
+There are two problems inherent with password shadowing in
+.Tn NIS
+that users should
+be aware of:
+.Bl -enum -offset indent
+.It
+The
+.Sq TCP port less than 1024
+test is trivial to defeat for users with
+unrestricted access to machines on your network (even those machines
+which do not run UNIX-based operating systems).
+.It
+If you plan to use a
+.Fx
+system to serve
+.No non- Ns Fx
+clients that
+have no support for password shadowing (which is most of them), you
+will have to disable the password shadowing entirely by uncommenting the
+.Em UNSECURE=True
+entry in
+.Pa /var/yp/Makefile .
+This will cause the standard
+.Pa passwd.byname
+and
+.Pa passwd.byuid
+maps to be generated with valid encrypted password fields, which is
+necessary in order for
+.No non- Ns Fx
+clients to perform user
+authentication through
+.Tn NIS .
+.El
+.Pp
+.Ss Security
+In general, any remote user can issue an RPC to
+.Nm
+and retrieve the contents of your
+.Tn NIS
+maps, provided the remote user
+knows your domain name.
+To prevent such unauthorized transactions,
+.Nm
+supports a feature called
+.Pa securenets
+which can be used to restrict access to a given set of hosts.
+At startup,
+.Nm
+will attempt to load the securenets information from a file
+called
+.Pa /var/yp/securenets .

+If
+.Nm
+receives a request from an address that matches one of these rules,
+it will process the request normally.
+If the address fails to match
+a rule, the request will be ignored and a warning message will be
+logged.
+If the
+.Pa /var/yp/securenets
+file does not exist,
+.Nm
+will allow connections from any host.
+.Pp
+The
+.Nm
+program also has support for Wietse Venema's
+.Em tcpwrapper
+package.
+This allows the administrator to use the tcpwrapper
+configuration files
+.Pa ( /etc/hosts.allow
+and
+.Pa /etc/hosts.deny )
+for access control instead of
+.Pa /var/yp/securenets .
+.Pp
+Note: while both of these access control mechanisms provide some
+security, they, like the privileged port test, are both vulnerable
+to
+.Dq IP spoofing
+attacks.
+.Pp
+.Ss NIS v1 compatibility
+This version of
+.Nm
+has some support for serving
+.Tn NIS
+v1 clients.
+The
+.Fx
+.Tn NIS
+implementation only uses the
+.Tn NIS
+v2 protocol, however other implementations
+include support for the v1 protocol for backwards compatibility
+with older systems.
+The
+.Xr ypbind 8
+daemons supplied with these systems will try to establish a binding
+to an
+.Tn NIS
+v1 server even though they may never actually need it (and they may
+persist in broadcasting in search of one even after they receive a
+response from a v2 server). Note that while
+support for normal client calls is provided, this version of
+.Nm
+does not handle v1 map transfer requests; consequently, it cannot
+be used as a master or slave in conjunction with older
+.Tn NIS
+servers that
+only support the v1 protocol.
+Fortunately, there probably aren't any
+such servers still in use today.
+.Ss NIS servers that are also NIS clients
+Care must be taken when running
+.Nm
+in a multi-server domain where the server machines are also
+.Tn NIS
+clients.
+It is generally a good idea to force the servers to
+bind to themselves rather than allowing them to broadcast bind
+requests and possibly become bound to each other: strange failure
+modes can result if one server goes down and
+others are dependent upon on it.
+(Eventually all the clients will
+time out and attempt to bind to other servers, but the delay
+involved can be considerable and the failure mode is still present
+since the servers might bind to each other all over again).
+.Pp
+Refer to the
+.Xr ypbind 8
+man page for details on how to force it to bind to a particular
+server.
+.Sh OPTIONS
+The following options are supported by
+.Nm :
+.Bl -tag -width flag
+.It Fl n
+This option affects the way
+.Nm
+handles yp_match requests for the
+.Pa hosts.byname
+and
+.Pa hosts.byaddress
+maps.
+By default, if
+.Nm
+can't find an entry for a given host in its hosts maps, it will
+return an error and perform no further processing.
+With the
+.Fl n
+flag,
+.Nm
+will go one step further: rather than giving up immediately, it
+will try to resolve the hostname or address using a DNS nameserver
+query.
+If the query is successful,
+.Nm
+will construct a fake database record and return it to the client,
+thereby making it seem as though the client's yp_match request
+succeeded.
+.Pp
+This feature is provided for compatiblity with SunOS 4.1.x,
+which has brain-damaged resolver functions in its standard C
+library that depend on
+.Tn NIS
+for hostname and address resolution.
+The
+.Fx
+resolver can be configured to do DNS
+queries directly, therefore it is not necessary to enable this
+option when serving only
+.Fx
+.Tn NIS
+clients.
+.It Fl d
+Cause the server to run in debugging mode.
+Normally,
+.Nm
+reports only unusual errors (access violations, file access failures)
+using the
+.Xr syslog 3
+facility.
+In debug mode, the server does not background
+itself and prints extra status messages to stderr for each
+request that it receives.
+Also, while running in debug mode,
+.Nm
+will not spawn any additional subprocesses as it normally does
+when handling yp_all requests or doing DNS lookups.
+(These actions
+often take a fair amount of time to complete and are therefore handled
+in subprocesses, allowing the parent server process to go on handling
+other requests.)
+This makes it easier to trace the server with
+a debugging tool.
+.It Fl p Ar path
+Normally,
+.Nm
+assumes that all
+.Tn NIS
+maps are stored under
+.Pa /var/yp .
+The
+.Fl p
+flag may be used to specify an alternate
+.Tn NIS
+root path, allowing
+the system administrator to move the map files to a different place
+within the filesystem.

+.Xr ypbind 8
+which YP server process to use
+.Sh SYNOPSIS
+.Nm
+.Op Fl h Ar host
+.Op Fl d Ar domain
+.Ar server
+.Sh DESCRIPTION
+.Nm Ypset
+tells the
+.Xr ypbind 8
+process on the current machine which YP server process to communicate with.
+If
+.Ar server
+is down or is not running a YP server process, it is not discovered until
+a YP client process attempts to access a YP map, at which time
+.Xr ypbind 8
+tests the binding and takes appropriate action.
+.Pp
+.Nm Ypset
+is most useful for binding a YP client that is not on the same broadcast
+network as the closest YP server, but can also be used for debugging
+a local network's YP configuration, testing specific YP client
+programs, or binding to a specific server when there are many servers on
+the local network supplying YP maps.
+.Pp
+The options are as follows:
+.Bl -tag -width indent
+.It Fl h Ar host
+Set the YP binding on
+.Ar host
+instead of the local machine.
+.It Fl d Ar domain
+Use the YP domain
+.Ar domain
+instead of the default domain as returned by
+.Xr domainname 1 .

+(Since this code will be treated as "part of the implementation" in some places
+and as "part of the application" in others, there's no good way to name
+functions, such as timegm, that are not part of the proposed ANSI C standard;
+such functions have kept their old, underscore-free names in this update.)
+
+And the "dysize" function has disappeared; it was present to allow compilation
+of the "date" command on old BSD systems, and a version of "date" is now
+provided in the package.  The "date" command is not created when you "make all"
+since it may lack options provided by the version distributed with your
+operating system, or may not interact with the system in the same way the
+native version does.
+
+Since POSIX frowns on correct leap second handling, the default behavior of
+the "zic" command (in the absence of a "-L" option) has been changed to omit
+leap second information from its output files.
+
+Be sure to read the comments in "Makefile" and make any changes
+needed to make things right for your system.
+
+To use the new functions, use a "-ltz" option when compiling or linking.
+
+Historical local time information has been included here not because it
+is particularly useful, but rather to:
+
+*	give an idea of the variety of local time rules that have
+	existed in the past and thus an idea of the variety that may be
+	expected in the future;
+
+*	provide a test of the generality of the local time rule description
+	system.
+
+The information in the time zone data files is by no means authoritative;
+if you know that the rules are different from those in a file, by all means
+feel free to change file (and please send the changed version to
+tz@elsie.nci.nih.gov for use in the future).  Europeans take note!

+----- Outline -----
+
+	Time and date functions
+	Names of time zone regions
+	Time zone abbreviations
+
+
+----- Time and date functions -----
+
+These time and date functions are upwards compatible with POSIX.1,
+an international standard for Unix-like systems.
+As of this writing, the current edition of POSIX.1 is:
+
+  Information technology --Portable Operating System Interface (POSIX (R))
+  -- Part 1: System Application Program Interface (API) [C Language]
+  ISO/IEC 9945-1:1996
+  ANSI/IEEE Std 1003.1, 1996 Edition
+  1996-07-12
+
+POSIX.1 has the following properties and limitations.
+
+*	In POSIX.1, time display in a process is controlled by the
+	environment variable TZ.  Unfortunately, the POSIX.1 TZ string takes
+	a form that is hard to describe and is error-prone in practice.
+	Also, POSIX.1 TZ strings can't deal with other (for example, Israeli)
+	daylight saving time rules, or situations where more than two
+	time zone abbreviations are used in an area.
+
+	The POSIX.1 TZ string takes the following form:
+
+		stdoffset[dst[offset],date[/time],date[/time]]
+
+	where:
+	
+	std and dst
+		are 3 or more characters specifying the standard
+		and daylight saving time (DST) zone names.
+	offset
+		is of the form `[-]hh:[mm[:ss]]' and specifies the
+		offset west of UTC.  The default DST offset is one hour
+		ahead of standard time.
+	date[/time],date[/time]
+		specifies the beginning and end of DST.  If this is absent,
+		the system supplies its own rules for DST, and these can
+		differ from year to year; typically US DST rules are used.
+	time
+		takes the form `hh:[mm[:ss]]' and defaults to 02:00.
+	date
+		takes one of the following forms:
+		Jn (1<=n<=365)
+			origin-1 day number not counting February 29
+		n (0<=n<=365)
+			origin-0 day number counting February 29 if present
+		Mm.n.d (0[Sunday]<=d<=6[Saturday], 1<=n<=5, 1<=m<=12)
+			for the dth day of week n of month m of the year,
+			where week 1 is the first week in which day d appears,
+			and `5' stands for the last week in which day d appears
+			(which may be either the 4th or 5th week).
+
+*	In POSIX.1, when a TZ value like "EST5EDT" is parsed,
+	typically the current US DST rules are used,
+	but this means that the US DST rules are compiled into each program
+	that does time conversion.  This means that when US time conversion
+	rules change (as in the United States in 1987), all programs that
+	do time conversion must be recompiled to ensure proper results.
+
+*	In POSIX.1, there's no tamper-proof way for a process to learn the
+	system's best idea of local wall clock.  (This is important for
+	applications that an administrator wants used only at certain times--
+	without regard to whether the user has fiddled the "TZ" environment
+	variable.  While an administrator can "do everything in UTC" to get
+	around the problem, doing so is inconvenient and precludes handling
+	daylight saving time shifts--as might be required to limit phone
+	calls to off-peak hours.)
+
+*	POSIX.1 requires that systems ignore leap seconds.
+
+These are the extensions that have been made to the POSIX.1 functions:
+
+*	The "TZ" environment variable is used in generating the name of a file
+	from which time zone information is read (or is interpreted a la
+	POSIX); "TZ" is no longer constrained to be a three-letter time zone
+	name followed by a number of hours and an optional three-letter
+	daylight time zone name.  The daylight saving time rules to be used
+	for a particular time zone are encoded in the time zone file;
+	the format of the file allows U.S., Australian, and other rules to be
+	encoded, and allows for situations where more than two time zone
+	abbreviations are used.
+
+	It was recognized that allowing the "TZ" environment variable to
+	take on values such as "America/New_York" might cause "old" programs
+	(that expect "TZ" to have a certain form) to operate incorrectly;
+	consideration was given to using some other environment variable
+	(for example, "TIMEZONE") to hold the string used to generate the
+	time zone information file name.  In the end, however, it was decided
+	to continue using "TZ":  it is widely used for time zone purposes;
+	separately maintaining both "TZ" and "TIMEZONE" seemed a nuisance;
+	and systems where "new" forms of "TZ" might cause problems can simply
+	use TZ values such as "EST5EDT" which can be used both by
+	"new" programs (a la POSIX) and "old" programs (as zone names and
+	offsets).
+
+*	To handle places where more than two time zone abbreviations are used,
+	the functions "localtime" and "gmtime" set tzname[tmp->tm_isdst]
+	(where "tmp" is the value the function returns) to the time zone
+	abbreviation to be used.  This differs from POSIX.1, where the elements
+	of tzname are only changed as a result of calls to tzset.
+
+*	Since the "TZ" environment variable can now be used to control time
+	conversion, the "daylight" and "timezone" variables are no longer
+	needed.  (These variables are defined and set by "tzset"; however, their
+	values will not be used by "localtime.")
+
+*	The "localtime" function has been set up to deliver correct results
+	for near-minimum or near-maximum time_t values.  (A comment in the
+	source code tells how to get compatibly wrong results).
+
+*	A function "tzsetwall" has been added to arrange for the system's
+	best approximation to local wall clock time to be delivered by
+	subsequent calls to "localtime."  Source code for portable
+	applications that "must" run on local wall clock time should call
+	"tzsetwall();" if such code is moved to "old" systems that don't
+	provide tzsetwall, you won't be able to generate an executable program.
+	(These time zone functions also arrange for local wall clock time to be
+	used if tzset is called--directly or indirectly--and there's no "TZ"
+	environment variable; portable applications should not, however, rely
+	on this behavior since it's not the way SVR2 systems behave.)
+
+*	These functions can account for leap seconds, thanks to Bradley White
+	(bww@k.cs.cmu.edu).
+
+Points of interest to folks with other systems:
+
+*	This package is already part of many POSIX-compliant hosts,
+	including BSD, HP, Linux, Network Appliance, SCO, SGI, and Sun.
+	On such hosts, the primary use of this package
+	is to update obsolete time zone rule tables.
+	To do this, you may need to compile the time zone compiler
+	`zic' supplied with this package instead of using the system `zic',
+	since the format of zic's input changed slightly in late 1994,
+	and many vendors still do not support the new input format.
+
+*	The Unix Version 7 "timezone" function is not present in this package;
+	it's impossible to reliably map timezone's arguments (a "minutes west
+	of GMT" value and a "daylight saving time in effect" flag) to a
+	time zone abbreviation, and we refuse to guess.
+	Programs that in the past used the timezone function may now examine
+	tzname[localtime(&clock)->tm_isdst] to learn the correct time
+	zone abbreviation to use.  Alternatively, use
+	localtime(&clock)->tm_zone if this has been enabled.
+
+*	The 4.2BSD gettimeofday function is not used in this package.
+	This formerly let users obtain the current UTC offset and DST flag,
+	but this functionality was removed in later versions of BSD.
+
+*	In SVR2, time conversion fails for near-minimum or near-maximum
+	time_t values when doing conversions for places that don't use UTC.
+	This package takes care to do these conversions correctly.
+
+The functions that are conditionally compiled if STD_INSPIRED is defined
+should, at this point, be looked on primarily as food for thought.  They are
+not in any sense "standard compatible"--some are not, in fact, specified in
+*any* standard.  They do, however, represent responses of various authors to
+standardization proposals.
+
+Other time conversion proposals, in particular the one developed by folks at
+Hewlett Packard, offer a wider selection of functions that provide capabilities
+beyond those provided here.  The absence of such functions from this package
+is not meant to discourage the development, standardization, or use of such
+functions.  Rather, their absence reflects the decision to make this package
+contain valid extensions to POSIX.1, to ensure its broad
+acceptability.  If more powerful time conversion functions can be standardized,
+so much the better.
+
+
+----- Names of time zone rule files -----
+
+The names of this package's installed time zone rule files are chosen to
+help minimize possible future incompatibilities due to political events.
+Ordinarily, names of countries are not used, to avoid incompatibilities
+when countries change their name (e.g. Zaire->Congo) or
+when locations change countries (e.g. Hong Kong from UK colony to China).
+
+Names normally have the form AREA/LOCATION, where AREA is the name
+of a continent or ocean, and LOCATION is the name of a specific
+location within that region.  North and South America share the same
+area, `America'.  Typical names are `Africa/Cairo', `America/New_York',
+and `Pacific/Honolulu'.
+
+Here are the general rules used for choosing location names,
+in decreasing order of importance:
+
+	Use only valid Posix file names.  Use only Ascii letters, digits, `.',
+		`-' and `_'.  Do not exceed 14 characters or start with `-'.
+		E.g. prefer `Brunei' to `Bandar_Seri_Begawan'.
+	Include at least one location per time zone rule set per country.
+		One such location is enough.
+	If all the clocks in a country's region have agreed since 1970,
+		don't bother to include more than one location
+		even if subregions' clocks disagreed before 1970.
+		Otherwise these tables would become annoyingly large.
+	If a name is ambiguous, use a less ambiguous alternative;
+		e.g. many cities are named San Jose and Georgetown, so
+		prefer `Costa_Rica' to `San_Jose' and `Guyana' to `Georgetown'.
+	Keep locations compact.  Use cities or small islands, not countries
+		or regions, so that any future time zone changes do not split
+		locations into different time zones.  E.g. prefer `Paris'
+		to `France', since France has had multiple time zones.
+	Use traditional English spelling, e.g. prefer `Rome' to `Roma', and
+		prefer `Athens' to the true name (which uses Greek letters).
+		The Posix file name restrictions encourage this rule.
+	Use the most populous among locations in a country's time zone,
+		e.g. prefer `Shanghai' to `Beijing'.  Among locations with
+		similar populations, pick the best-known location,
+		e.g. prefer `Rome' to `Milan'.
+	Use the singular form, e.g. prefer `Canary' to `Canaries'.
+	Omit common suffixes like `_Islands' and `_City', unless that
+		would lead to ambiguity.  E.g. prefer `Cayman' to
+		`Cayman_Islands' and `Guatemala' to `Guatemala_City',
+		but prefer `Mexico_City' to `Mexico' because the country
+		of Mexico has several time zones.
+	Use `_' to represent a space.
+	Omit `.' from abbreviations in names, e.g. prefer `St_Helena'
+		to `St._Helena'.
+
+The file `zone.tab' lists the geographical locations used to name
+time zone rule files.
+
+Older versions of this package used a different naming scheme,
+and these older names are still supported.
+See the file `backwards' for most of these older names
+(e.g. `US/Eastern' instead of `America/New_York').
+The other old-fashioned names still supported are
+`WET', `CET', `MET', `EET' (see the file `europe'),
+and `Factory' (see the file `factory').
+
+
+----- Time zone abbreviations -----
+
+When this package is installed, it generates time zone abbreviations
+like `EST' to be compatible with human tradition and POSIX.1.
+Here are the general rules used for choosing time zone abbreviations,
+in decreasing order of importance:
+
+	Use abbreviations that consist of 3 or more upper-case Ascii letters,
+		except use "___" for locations while uninhabited.
+		Posix.1 requires at least 3 characters, and the restriction to
+		upper-case Ascii letters follows most traditions.
+		Previous editions of this database also used characters like
+		' ' and '?', but these characters have a special meaning to
+		the shell and cause commands like
+			set `date`
+		to have unexpected effects.  In theory, the character set could
+		be !%./@A-Z^_a-z{}, but these tables use only upper-case
+		Ascii letters (and "___").
+	Use abbreviations that are in common use among English-speakers,
+		e.g. `EST' for Eastern Standard Time in North America.
+		We assume that applications translate them to other languages
+		as part of the normal localization process; for example,
+		a French application might translate `EST' to `HNE'.
+	For zones whose times are taken from a city's longitude, use the
+		traditional xMT notation, e.g. `PMT' for Paris Mean Time.
+		The only name like this in current use is `GMT'.
+	If there is no common English abbreviation, abbreviate the English
+		translation of the usual phrase used by native speakers.
+		If this is not available or is a phrase mentioning the country
+		(e.g. ``Cape Verde Time''), then:
+
+		When a country has a single or principal time zone region,
+			append `T' to the country's ISO	code, e.g. `CVT' for
+			Cape Verde Time.  For summer time append `ST';
+			for double summer time append `DST'; etc.
+		When a country has multiple time zones, take the first three
+			letters of an English place name identifying each zone
+			and then append `T', `ST', etc. as before;
+			e.g. `VLAST' for VLAdivostok Summer Time.
+
+Application writers should note that these abbreviations are ambiguous
+in practice: e.g. `EST' has a different meaning in Australia than
+it does in the United States.  In new applications, it's often better
+to use numeric UTC offsets like `-0500' instead of time zone
+abbreviations like `EST'; this avoids the ambiguity.

+.Sh NAME
+.Nm zic
+.Nd timezone compiler
+.Sh SYNOPSIS
+.Nm
+.Op Fl Dsv
+.Op Fl d Ar directory
+.Op Fl g Ar group
+.Op Fl L Ar leapsecondfilename
+.Op Fl l Ar localtime
+.Op Fl m Ar mode
+.Op Fl p Ar posixrules
+.Op Fl u Ar user
+.Op Fl y Ar command
+.Op Ar filename ...
+.Sh DESCRIPTION
+.Nm Zic
+reads text from the file(s) named on the command line
+and creates the time conversion information files specified in this input.
+If a
+.Ar filename
+is
+.Em - ,
+the standard input is read.
+.Pp
+The following options are available:
+.Bl -tag -width indent
+.It Fl D
+Do not automatically create directories.  If the input file(s) specify
+an output file in a directory which does not already exist, the
+default behavior is to attempt to create the directory.  If
+.Fl D
+is specified,
+.Nm
+will instead error out immediately.
+.It Fl d Ar directory
+Create time conversion information files in the named directory rather than
+in the standard directory named below.
+.It Fl g Ar group
+After creating each output file, change its group ownership to the
+specified
+.Ar group
+(which can be either a name or a numeric group ID).
+.It Fl L Ar leapsecondfilename
+Read leap second information from the file with the given name.
+If this option is not used,
+no leap second information appears in output files.
+.It Fl l Ar timezone
+Use the given
+.Ar time zone
+as local time.
+.Nm Zic
+will act as if the input contained a link line of the form
+.Bd -literal -offset indent
+.No "Link	timezone		localtime
+.Ed
+(Note that this action has no effect on
+.Fx ,
+since the local time zone is specified in
+.Pa /etc/localtime
+and not
+.Pa /usr/share/zoneinfo/localtime . )
+.It Fl m Ar mode
+After creating each output file, change its access mode to
+.Ar mode .
+Both numeric and alphabetic modes are accepted
+(see
+.Xr chmod 1 ) .
+.It Fl p Ar timezone
+Use the given
+.Ar "time zone" Ns 's
+rules when handling POSIX-format
+time zone environment variables.
+.Nm Zic
+will act as if the input contained a link line of the form
+.Bd -literal -offset indent
+.No "Link	timezone		posixrules
+.Ed
+.It Fl u Ar user
+After creating each output file, change its owner to
+.Ar user
+(which can be either a name or a numeric user ID).
+.It Fl v
+Complain if a year that appears in a data file is outside the range
+of years representable by
+.Xr time 3
+values.
+.It Fl s
+Limit time values stored in output files to values that are the same
+whether they're taken to be signed or unsigned.
+You can use this option to generate SVVS-compatible files.
+.It Fl y Ar command
+Use the given
+.Ar command
+rather than
+.Em yearistype
+when checking year types (see below).
+.El
+.Pp
+Input lines are made up of fields.
+Fields are separated from one another by any number of white space characters.
+Leading and trailing white space on input lines is ignored.
+An unquoted sharp character (#) in the input introduces a comment which extends
+to the end of the line the sharp character appears on.
+White space characters and sharp characters may be enclosed in double quotes
+(") if they're to be used as part of a field.
+Any line that is blank (after comment stripping) is ignored.
+Non-blank lines are expected to be of one of three types:
+rule lines, zone lines, and link lines.
+.Pp
+A rule line has the form:
+.Dl "Rule	NAME	FROM	TO	TYPE	IN	ON		AT	SAVE	LETTER/S
+For example:
+.Dl "Rule	US	1967	1973	\-	Apr	lastSun	2:00	1:00	D
+.Pp
+The fields that make up a rule line are:
+.Bl -tag -width "LETTER/S" -offset indent
+.It NAME
+Give the (arbitrary) name of the set of rules this rule is part of.
+.It FROM
+Give the first year in which the rule applies.
+Any integer year can be supplied; the Gregorian calendar is assumed.
+The word
+.Em minimum
+(or an abbreviation) means the minimum year representable as an integer.
+The word
+.Em maximum
+(or an abbreviation) means the maximum year representable as an integer.
+Rules can describe times that are not representable as time values,
+with the unrepresentable times ignored; this allows rules to be portable
+among hosts with differing time value types.
+.It TO
+Give the final year in which the rule applies.
+In addition to
+.Em minimum
+and
+.Em maximum
+(as above),
+the word
+.Em only
+(or an abbreviation)
+may be used to repeat the value of the
+.Em FROM
+field.
+.It TYPE
+Give the type of year in which the rule applies.
+If
+.Em TYPE
+is
+.Em \-
+then the rule applies in all years between
+.Em FROM
+and
+.Em TO
+inclusive.
+If
+.Em TYPE
+is something else, then
+.Nm
+executes the command
+.Li yearistype Ar year Ar type
+to check the type of a year:
+an exit status of zero is taken to mean that the year is of the given type;
+an exit status of one is taken to mean that the year is not of the given type.
+.It IN
+Name the month in which the rule takes effect.
+Month names may be abbreviated.
+.It ON
+Give the day on which the rule takes effect.
+Recognized forms include:
+.Pp
+.Bl -tag -width lastSun -compact -offset indent
+.It \&5
+the fifth of the month
+.It lastSun
+the last Sunday in the month
+.It lastMon
+the last Monday in the month
+.It Sun>=8
+first Sunday on or after the eighth
+.It Sun<=25
+last Sunday on or before the 25th
+.El
+.Pp
+Names of days of the week may be abbreviated or spelled out in full.
+Note that there must be no spaces within the
+.Em ON
+field.
+.It AT
+Give the time of day at which the rule takes effect.
+Recognized forms include:
+.Pp
+.Bl -tag -width "\&1:28:14" -offset indent -compact
+.It 2
+time in hours
+.It 2:00
+time in hours and minutes
+.It 15:00
+24-hour format time (for times after noon)
+.It 1:28:14
+time in hours, minutes, and seconds
+.El
+.Pp
+where hour 0 is midnight at the start of the day,
+and hour 24 is midnight at the end of the day.
+Any of these forms may be followed by the letter
+.Sq Li w
+if the given time is local
+.Dq "wall clock"
+time,
+.Sq Li s
+if the given time is local
+.Dq standard
+time, or
+.Sq Li u
+(or
+.Sq Li g
+or
+.Sq Li z )
+if the given time is universal time;
+in the absence of an indicator,
+wall clock time is assumed.
+.It SAVE
+Give the amount of time to be added to local standard time when the rule is in
+effect.
+This field has the same format as the
+.Em AT
+field
+(although, of course, the
+.Sq Li w
+and
+.Sq Li s
+suffixes are not used).
+.It LETTER/S
+Give the
+.Dq "variable part"
+(for example, the
+.Dq S
+or
+.Dq D
+in
+.Dq EST
+or
+.Dq EDT )
+of time zone abbreviations to be used when this rule is in effect.
+If this field is
+.Em \- ,
+the variable part is null.
+.El
+.Pp
+A zone line has the form:
+.Dl "Zone	NAME	GMTOFF	RULES/SAVE	FORMAT	[UNTIL]
+For example:
+.Dl "Zone	Australia/Adelaide	9:30	Aus	CST	1971 Oct 31 2:00
+The fields that make up a zone line are:
+.Bl -tag -width indent
+.It NAME
+The name of the time zone.
+This is the name used in creating the time conversion information file for the
+zone.
+.It GMTOFF
+The amount of time to add to UTC to get standard time in this zone.
+This field has the same format as the
+.Em AT
+and
+.Em SAVE
+fields of rule lines;
+begin the field with a minus sign if time must be subtracted from UTC.
+.It RULES/SAVE
+The name of the rule(s) that apply in the time zone or,
+alternately, an amount of time to add to local standard time.
+If this field is
+.Em \-
+then standard time always applies in the time zone.
+.It FORMAT
+The format for time zone abbreviations in this time zone.
+The pair of characters
+.Em %s
+is used to show where the
+.Dq "variable part"
+of the time zone abbreviation goes.
+Alternately,
+a slash (/)
+separates standard and daylight abbreviations.
+.It UNTIL
+The time at which the UTC offset or the rule(s) change for a location.
+It is specified as a year, a month, a day, and a time of day.
+If this is specified,
+the time zone information is generated from the given UTC offset
+and rule change until the time specified.
+The month, day, and time of day have the same format as the IN, ON, and AT
+columns of a rule; trailing columns can be omitted, and default to the
+earliest possible value for the missing columns.
+.Pp
+The next line must be a
+.Dq continuation
+line; this has the same form as a zone line except that the
+string
+.Dq Zone
+and the name are omitted, as the continuation line will
+place information starting at the time specified as the
+.Em UNTIL
+field in the previous line in the file used by the previous line.
+Continuation lines may contain an
+.Em UNTIL
+field, just as zone lines do, indicating that the next line is a further
+continuation.
+.El
+.Pp
+A link line has the form
+.Dl "Link	LINK-FROM	LINK-TO
+For example:
+.Dl "Link	Europe/Istanbul	Asia/Istanbul
+The
+.Em LINK-FROM
+field should appear as the
+.Em NAME
+field in some zone line;
+the
+.Em LINK-TO
+field is used as an alternate name for that zone.
+.Pp
+Except for continuation lines,
+lines may appear in any order in the input.
+.Pp
+Lines in the file that describes leap seconds have the following form:
+.Dl "Leap	YEAR	MONTH	DAY	HH:MM:SS	CORR	R/S
+For example:
+.Dl "Leap	1974	Dec	31	23:59:60	+	S
+The
+.Em YEAR ,
+.Em MONTH ,
+.Em DAY ,
+and
+.Em HH:MM:SS
+fields tell when the leap second happened.
+The
+.Em CORR
+field
+should be
+.Dq +
+if a second was added
+or
+.Dq -
+if a second was skipped.
+.\" There's no need to document the following, since it's impossible for more
+.\" than one leap second to be inserted or deleted at a time.
+.\" The C Standard is in error in suggesting the possibility.
+.\" See Terry J Quinn, The BIPM and the accurate measure of time,
+.\" Proc IEEE 79, 7 (July 1991), 894-905.
+.\"	or
+.\"	.q ++
+.\"	if two seconds were added
+.\"	or
+.\"	.q --
+.\"	if two seconds were skipped.
+The
+.Em R/S
+field
+should be (an abbreviation of)
+.Dq Stationary
+if the leap second time given by the other fields should be interpreted as UTC
+or
+(an abbreviation of)
+.Dq Rolling
+if the leap second time given by the other fields should be interpreted as
+local wall clock time.
+.Sh NOTE
+For areas with more than two types of local time,
+you may need to use local standard time in the
+.Em AT
+field of the earliest transition time's rule to ensure that
+the earliest transition time recorded in the compiled file is correct.
