XFS(1)                                                                  XFS(1)

       xfs - X font server

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

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

       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.

       -config configuration_file
               Specifies  the  configuration  file  the font server will use.  If this parameter is not specified, the
               default file, /etc/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 speci-
               fied, xfs will run as a regular process (unless xfs was built to daemonize by default).

               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.

               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.

       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.

       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.  The current implementation only supports  a  single  catalogue
              ("all")  containing  all  of the specified fonts. A special directory with symlinks to font paths can be
              specified using a catalogue:<dir> entry. See the CATALOGUE DIR section below for details.

       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

       You  can  specify  a  special kind of font path in the form catalogue:<dir>.  The directory specified after the
       catalogue: prefix will be scanned for symlinks and each symlink destination will be added as a  local  fontfile

       The  symlink  can  be suffixed by attributes such as 'unscaled', which will be passed through to the underlying
       fontfile FPE. The only exception is the newly introduced 'pri' attribute, which will be used for  ordering  the
       font paths specified by the symlinks.

       An example configuration:

           75dpi:unscaled:pri=20 -> /usr/share/X11/fonts/75dpi
           ghostscript:pri=60 -> /usr/share/fonts/default/ghostscript
           misc:unscaled:pri=10 -> /usr/share/X11/fonts/misc
           type1:pri=40 -> /usr/share/X11/fonts/Type1
           type1:pri=50 -> /usr/share/fonts/default/Type1

       This will add /usr/share/X11/fonts/misc as the first FPE with the attribute the attribute unscaled etc. This is
       functionally equivalent to setting the following font path:


       # 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,

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

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

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


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

       Examples: tcp/, tcp/

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


       The nodename specifies the name (or decimal numeric address) of the machine on which the font  server  is  run-
       ning.   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.
