XFS(1)                  FreeBSD General Commands Manual                 XFS(1)

NAME
       xfs - X font server

SYNOPSIS
       xfs [-config configuration_file] [-daemon] [-droppriv] [-ls
       listen_socket] [-nodaemon] [-port tcp_port] [-user username]

DESCRIPTION
       Xfs is the X Window System font server.  It supplies fonts to X Window
       System display servers.

STARTING THE SERVER
       The server is usually run by a system administrator, and started via
       boot files like /etc/rc.local.  Users may also wish to start private
       font servers for specific sets of fonts.

OPTIONS
       -config configuration_file
               Specifies the configuration file the font server will use.  If
               this parameter is not specified, the default file,
               /usr/X11R6/lib/X11/fs/config will be used.

       -ls listen_socket
               Specifies a file descriptor which is already set up to be used
               as the listen socket.  This option is only intended to be used
               by the font server itself when automatically spawning another
               copy of itself to handle additional connections.

       -port tcp_port
               Specifies the TCP port number on which the server will listen
               for connections.  The default port number is 7100.

       -daemon Instructs xfs to fork and go into the background automatically
               at startup  If this option is not specified, xfs will run as a
               regular process (unless xfs was built to daemonize by default).

       -droppriv
               If specified, xfs will attempt to run as user and group xfs
               (unless the -user option is used). This has been implemented
               for security reasons, as xfs may have undiscovered buffer
               overflows or other paths for possible exploit, both local and
               remote.  With this option, you may also wish to specify "no-
               listen = tcp" in the config file, which ensures that xfs will
               not to use a TCP port at all.

       -nodaemon
               When xfs is built to daemonize (run in the background) by
               default, this prevents that and starts xfs up as a regular
               process.

       -user username
               This is equivalent to -droppriv except that xfs will run as
               user username.

SIGNALS
       SIGTERM This causes the font server to exit cleanly.

       SIGUSR1 This signal is used to cause the server to re-read its
               configuration file.

       SIGUSR2 This signal is used to cause the server to flush any cached
               data it may have.

       SIGHUP  This signal is used to cause the server to reset, closing all
               active connections and re-reading the configuration file.

CONFIGURATION
       The configuration language is a list of keyword and value pairs.  Each
       keyword is followed by an '=' and then the desired value.

       Recognized keywords include:

       catalogue (list of string)
              Ordered list of font path element names.  Use of the keyword
              "catalogue" is very misleading at present, the current
              implementation only supports a single catalogue ("all"),
              containing all of the specified fonts.

       alternate-servers (list of string)
              List of alternate servers for this font server.

       client-limit (cardinal)
              Number of clients this font server will support before refusing
              service.  This is useful for tuning the load on each individual
              font server.

       clone-self (boolean)
              Whether this font server should attempt to clone itself when it
              reachs the client-limit.

       default-point-size (cardinal)
              The default pointsize (in decipoints) for fonts that don't
              specify.  The default is 120.

       default-resolutions (list of resolutions)
              Resolutions the server supports by default.  This information
              may be used as a hint for pre-rendering, and substituted for
              scaled fonts which do not specify a resolution.  A resolution is
              a comma-separated pair of x and y resolutions in pixels per
              inch.  Multiple resolutions are separated by commas.

       error-file (string)
              Filename of the error file.  All warnings and errors will be
              logged here.

       no-listen (trans-type)
              Disable a transport  type. For example, TCP/IP connections can
              be disabled with no-listen tcp

       port (cardinal)
              TCP port on which the server will listen for connections.

       use-syslog (boolean)
              Whether syslog(3) (on supported systems) is to be used for
              errors.

       deferglyphs (string)
              Set the mode for delayed fetching and caching of glyphs.  Value
              is "none", meaning deferred glyphs is disabled, "all", meaning
              it is enabled for all fonts, and "16", meaning it is enabled
              only for 16-bits fonts.

EXAMPLE
       #
       # sample font server configuration file
       #

       # allow a max of 10 clients to connect to this font server
       client-limit = 10

       # when a font server reaches its limit, start up a new one
       clone-self = on

       # alternate font servers for clients to use
       alternate-servers = hansen:7101,hansen:7102

       # where to look for fonts
       # the first is a set of Speedo outlines, the second is a set of
       # misc bitmaps and the last is a set of 100dpi bitmaps
       #
       catalogue = /usr/X11R6/lib/X11/fonts/speedo,
            /usr/X11R6/lib/X11/fonts/misc,
            /usr/X11R6/lib/X11/fonts/100dpi/

       # in 12 points, decipoints
       default-point-size = 120

       # 100 x 100 and 75 x 75
       default-resolutions = 100,100,75,75
       use-syslog = off

FONT SERVER NAMES
       One of the following forms can be used to name a font server that
       accepts TCP connections:

           tcp/hostname:port
           tcp/hostname:port/cataloguelist

       The hostname specifies the name (or decimal numeric address) of the
       machine on which the font server is running.  The port is the decimal
       TCP port on which the font server is listening for connections.  The
       cataloguelist specifies a list of catalogue names, with '+' as a
       separator.

       Examples: tcp/fs.x.org:7100, tcp/18.30.0.212:7101/all.

       One of the following forms can be used to name a font server that
       accepts DECnet connections:

           decnet/nodename::font$objname
           decnet/nodename::font$objname/cataloguelist

       The nodename specifies the name (or decimal numeric address) of the
       machine on which the font server is running.  The objname is a normal,
       case-insensitive DECnet object name.  The cataloguelist specifies a
       list of catalogue names, with '+' as a separator.

       Examples: DECnet/SRVNOD::FONT$DEFAULT,
       decnet/44.70::font$special/symbols.

BUGS
       Multiple catalogues should be supported.
