       xfs - X font server

       xfs   [-config  configuration_file]  [-daemon]  [-droppriv]  [-ls  lis-
       ten_socket] [-nodaemon] [-port tcp_port] [-user username]

       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,
	       /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).

	       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 over-
	       flows  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 pro-

       -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 configu-
	       ration 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.  Use of the keyword
	      "catalogue" is very misleading at present, the current implemen-
	      tation  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 spec-
	      ify.  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

       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.

       # 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 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	 sepa-

       Examples: tcp/fs.x.org:7100, 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 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/sym-

       Multiple catalogues should be supported.
