“Normally, we would recommend using the source code file from
the Nagios site to install NRPE. However, with FreeBSD, there are
at least two advantages to installing NRPE from the official
FreeBSD ports.“First, the source code file in FreeBSD ports is already
modified to work with FreeBSD. Second, FreeBSD ports contains many
FreeBSD-specific plugins that can be used with the FreeBSD version
of NRPE.”
