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