Problems wih NRPE. Really works?

[Chris Wilson]

Hi Yolanda,

The NRPE runs on the machine under test, not on the Nagios server. And
you don't need [x]inetd to launch NRPE commands, that's what the daemon
is for. 

Start nrpe on the machine under test, and run the check_nrpe plugin on
the Nagios server to check that you have NRPE set up and running
correctly.

Cheers, Chris.
