Check port versions - NRPE pkg version check

A nagios plugin I wrote, which checks the number of outdated ports on a system. If the number exceeds the configured limits, WARNING or CRITICAL is returned.

Download the plugin

The plugin can be downloaded to the correct place (and made executable) with the following commands:

sudo fetch -o /usr/local/libexec/nagios/check_portmaster http://www.gibfest.dk/check_portmaster
sudo chmod +x /usr/local/libexec/nagios/check_portmaster

Feel free to check the source code to see what it does, it is pretty simple and well commented.

Configuring NRPE

Add the following line to /usr/local/etc/nrpe.cfg:

command[check_portmaster]=/usr/local/libexec/nagios/check_portmaster

Remember to restart NRPE after changing the config:

sudo /usr/local/etc/rc.d/nrpe2 restart

Updating the portmaster output file

As mentioned in Check_portsindex_age_-_NRPE_ports_age_check I add the following line to /etc/crontab to both update ports, and create an updated /tmp/check_portmaster.tmp file:

0	3	*	*	*	root	/usr/sbin/portsnap cron && /usr/sbin/portsnap -I update && /usr/local/sbin/portmaster -L > /tmp/check_portmaster.tmp
