I run a cronjob every 2 minutes (kinda often, but it's not really service
impacting) called radmon.sh:
PATH=:/bin:/usr/bin:/usr/ucb:/usr/etc
hostname=`hostname`
admin="[EMAIL PROTECTED]"
# A little lock file for me to use when I'm testing stuff to
# keep this script from working
if [ -f /home/staff/aholtz/bin/lock ]; then
exit
fi
/bin/ps axwwww | grep radiusd | grep -v "grep" > /dev/null 2>&1
if [ $? -eq 0 ]; then
:
else
/etc/rc.radiator restart > /dev/null 2>&1
echo "Radius for $hostname not running!" | Mail -s "Radius \
for $hostname not running!" $admin
fi
That script (/etc/rc.radiator) is just another little shell script that
takes stop|start|reload|restart as a command line parameter (similiar to
other rc scripts). You could just replace that with your startup radius
command. Granted this isn't the most intricate of scripts and doesn't
really test whether radiusd is answering requests or not - it just looks
to be sure it is still running in memory. I suppose if your radiusd is
"hanging" in that it is running, but not answering requests you could
write a script to parse output from the command line answer from
radpwtst....
