Linux Server Crash Monitor Utility

[r00d]

Linux Outcast Server Monitor Tool © NTF

 

I whipped up a little script that will check to make sure outcast server is running, and if it's not, it will restart it. This script should be run every (1) minute by CRON.

# You'll need the PIDOF utility by Miquel van Smoorenburg

# for Linux for this to work, or else find another

# way to write the pid of the server to the jk2ded.pid file

# PIDOF is standard in many linux distributions.

#

# Run this script as a cron job, and it will check to make sure your server

# is up and running. If it finds the server down, it will restart it.

then

exit 0

echo "Stale pid file (erasing it)"

rm -f $JKPATH/$JKPIDFILE
