XCOMM This script manages the Xprint server side
XCOMM Basic support for IRIX-style "chkconfig"

XCOMM description: Startup/shutdown script for Xprint server(s)
XCOMM Basic support for the Linux Standard Base Specification 1.0.0
XCOMM (Note: The Should-Start/Stop lines are there so that this works in the
XCOMM future, when the LSB adopts these. The X-UnitedLinux lines are there
XCOMM so that it works right now.)

XCOMM###########################################################################
XCOMM
XCOMM This script has three main tasks:
XCOMM 1. Start Xprint servers ("Xprt") at boot time.
XCOMM 2. Shutdown Xprint servers when the machine is being shut down.
XCOMM 3. Query the list of available printers.
XCOMM
XCOMM Additional tasks are:
XCOMM 4. Restart ('restart'|'force-reload') and conditional restart
XCOMM ('condrestart'/'try-restart') for Linux support
XCOMM 5. Wrapping of application call with setting XPSERVERLIST ('wrapper')
XCOMM
XCOMM Usage:
XCOMM - Start Xprint server(s) manually:
XCOMM % /etc/init.d/xprint start
XCOMM
XCOMM - Stop Xprint server(s) manually:
XCOMM % /etc/init.d/xprint stop
XCOMM
XCOMM - Populate $XPSERVERLIST env var (for example as part of a global
XCOMM login script like /etc/profile or per-user login scripts like
XCOMM $HOME/.profile (sh/ksh/bash))
XCOMM % XPSERVERLIST="`/etc/init.d/xprint get_xpserverlist`"
XCOMM % export XPSERVERLIST
XCOMM
XCOMM Installation:
XCOMM Copy this script to /etc/init.d/xprint and make sure that it is
XCOMM executable. If your installation is LSB-compliant, then run
XCOMM % /usr/lib/lsb/install_initd /etc/init.d/xprint
XCOMM to start the service on startup. Otherwise, manually create links
XCOMM to the matching run levels.
XCOMM Examples:
XCOMM - Solaris 2.7/2.8/2.9:
XCOMM % cp xprint /etc/init.d/xprint
XCOMM % chmod a+rx /etc/init.d/xprint
XCOMM % ln /etc/init.d/xprint /etc/rc0.d/K38xprint
XCOMM % ln /etc/init.d/xprint /etc/rc1.d/K38xprint
XCOMM % ln /etc/init.d/xprint /etc/rc2.d/S81xprint
XCOMM % ln /etc/init.d/xprint /etc/rcS.d/K38xprint
XCOMM
XCOMM - SuSE Linux 7.3
XCOMM % cp xprint /etc/init.d/xprint
XCOMM % chmod a+rx /etc/init.d/xprint
XCOMM % ln -s ../xprint /etc/init.d/rc3.d/K13xprint
XCOMM % ln -s ../xprint /etc/init.d/rc3.d/S12xprint
XCOMM % ln -s ../xprint /etc/init.d/rc5.d/K13xprint
XCOMM % ln -s ../xprint /etc/init.d/rc5.d/S12xprint
XCOMM % ln -s ../xprint /etc/init.d/rc2.d/K13xprint
XCOMM % ln -s ../xprint /etc/init.d/rc2.d/S12xprint
XCOMM
XCOMM - SuSE Linux 6.4:
XCOMM % cp xprint /sbin/init.d/xprint
XCOMM % chmod a+rx /sbin/init.d/xprint
XCOMM % ln -s ../xprint /sbin/init.d/rc2.d/K20xprint
XCOMM % ln -s ../xprint /sbin/init.d/rc2.d/S20xprint
XCOMM % ln -s ../xprint /sbin/init.d/rc3.d/K20xprint
XCOMM % ln -s ../xprint /sbin/init.d/rc3.d/S20xprint
XCOMM
XCOMM Notes:
XCOMM - The Xprint servers must be started _after_ the print
XCOMM spooler or the server(s) may refuse to start
XCOMM - The script should be readable by all users to ensure that they
XCOMM can use the "get_xpserverlist"-option
XCOMM
XCOMM Custom configuration:
XCOMM - Edit the function setup_config() in this script to match your needs
XCOMM
XCOMM Known bugs/ToDo/Notes:
XCOMM - The shell script assumes that a Xserver can be reached via
XCOMM "hostname:displaynum" where "hostname" is obtained from
XCOMM "/usr/bin/hostname". It may happen that a kernel firewall
XCOMM blocks an X connection on the same host (e.g. client && Xserver
XCOMM are running on the same host).
XCOMM Suggested fix: Fix the firewall config.
XCOMM Suggested workaround: Edit this script and replace the use of
XCOMM /usr/bin/hostname with "echo 'localhost'".

XCOMM Known bugs:
XCOMM - there is no way in plain bourne shell or bash (see comment about ksh93
XCOMM below) to test if a Xserver sits only on a socket and not on a pipe
XCOMM - some Xserver's don't cleanup their stuff in /tmp on exit which may end
XCOMM in the problem that we don't detect possible free display numbers
