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'".
