NAME

fs − X font server

SYNOPSIS

fs [−config configuration_file] [−port tcp_port]

DESCRIPTION

Fs 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.

−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.

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.

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.

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

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.

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:7001,hansen:7002
 # 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/lib/fonts/speedo,
/usr/lib/X11/ncd/fonts/misc,
/usr/lib/X11/ncd/fonts/100dpi/
 # in 12 points, decipoints
default-point-size = 120
 # 100 x 100 and 75 x 75
default-resolutions = 100,100,75,75

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/expo.lcs.mit.edu:7000, tcp/18.30.0.212:7001/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.

Multiple catalogues should be supported.
