Startup script for VNC servers on Ubuntu

[maxibuntu]

Just worked on an initscript for VNC servers.

Put this one in /etc/init.d, name it vncservers and do a chmod +x /etc/init.d/vncservers

#!/bin/bash

# Scripted by Maxim Heijndijk

# chkconfig: 2345 91 35
# description: Starts and stops vncserver. \
# Used to provide remote X administration services.

### BEGIN INIT INFO

# Default-Stop: 0 1 6
# Required-Start: networking
# Required-Stop: networking
# Short-Description: Starts and stops vncserver

### END INIT INFO

VNCSERVERS=""

[ -f /etc/default/vncservers ] && . /etc/default/vncservers || exit 0

start() {

    ulimit -S -c 0 >/dev/null 2>&1

    RETVAL=0

    for display in ${VNCSERVERS}; do

	eval cd ~${display##*:}

	if [ -e ".vnc/passwd" ]; then

	    log_begin_msg "Starting VNC Server for user ${display##*:}:"

	    unset BASH_ENV ENV

	    su ${display##*:} -c "cd ~${display##*:} && vncserver :${display%%:*}"

	    RETVAL="$?"

	    if [ "$RETVAL" -ne 0 ]; then

		log_end_msg 1
	
		break

	    else

		log_end_msg 0

	    fi

	else

	    log_begin_msg "Not starting VNC Server for user ${display##*:}.\n   File \"~${display##*:}/.vnc/passwd\" not found.\n   Create a password file for the VNC server with vncpasswd"

	    log_end_msg 1

	fi

    done

    [ "$RETVAL" -eq 0 ] && touch "/var/lock/vncserver"

}

stop() {

    unset BASH_ENV ENV

    for display in ${VNCSERVERS}; do

	log_begin_msg "Shutting down VNC Server for user ${display##*:}: "

	su ${display##*:} -c "vncserver -kill :${display%%:*}" >/dev/null 2>&1

	RETVAL="$?"

	[ "$RETVAL" -eq 0 ] && log_end_msg 0 || log_end_msg 1

    done

    [ -f "/var/lock/vncserver" ] && rm -f "/var/lock/vncserver"

}

case "$1" in

    start)		start
			;;

    stop)		stop
			;;

    restart|reload)	stop
			start
			;;

    *)			echo $"Usage: $0 {start|stop|restart}"
			exit 1
			;;

esac

exit 0

Put this next one in /etc/default and name it vncservers. Edit to your likings.

# The VNCSERVERS variable is a list of display:user pairs.
#
# Uncomment the line below to start a VNC server on display :1
# as my 'myusername' (adjust this to your own). You will also
# need to set a VNC password; run 'man vncpasswd' to see how
# to do that.
#
# DO NOT RUN THIS SERVICE if your local area network is
# untrusted! For a secure way of using VNC, see
# <URL:http://www.uk.research.att.com/vnc/sshvnc.html>.

VNCSERVERS="1:ubuntu 2:joe"

# ubuntu's VNC options
VNCSERVERARGS[1]="-geometry 1024x768"

# joe's VNC options
VNCSERVERARGS[2]="-geometry 1280x1024"

Have fun.
