Check port versions - NRPE pkg version check
From TykWiki
A nagios plugin I wrote, which checks the number of outdated ports on a system.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
