- The title given to this article is incorrect due to [technical limitations]. The correct title is check_ports - NRPE portaudit check.
It is possible to monitor FreeBSD servers for outdated or vulnerable ports using Nagios and NRPE:
$ cat /usr/ports/net-mgmt/nagios-check_ports/pkg-descr Nagios Plugin to monitor your FreeBSD Ports Tree for updates or installed packages with known security vulnerabilities.
Configuring Nagios
Define a new service on the Nagios server, in /usr/local/etc/nagios/objects/services.cfg
:
define service{ use generic-service hostgroup_name freebsd-servers service_description nrpe_check_ports check_command check_nrpe2!check_ports }
I want all my FreeBSD servers to have their ports checked, so I added the hostgroup freebsd-servers
to this check. The FreeBSD servers I monitor in this Nagios installation are all members of the hostgroup freebsd-servers
.
Install the plugin
Just install the port, easy as it gets. It installs /usr/ports/ports-mgmt/portaudit
as a dependency, by the way:
sudo portmaster /usr/ports/net-mgmt/nagios-check_ports/
Note: If this is the first time Portaudit (installed as a dependency) is used on the server, you need to download a fresh audit database before it will work. If you do not download it manually, it will happen automatically each night (called from periodic). To download a fresh audit database manually, run:
sudo portaudit -F
Configuring NRPE
Add the following line to /usr/local/etc/nrpe.cfg
:
command[check_ports]=/usr/local/libexec/nagios/check_ports
Remember to restart NRPE after changing the config:
sudo /usr/local/etc/rc.d/nrpe2 restart
