Have you checked the setting in the nrep.cfg file? Like server_port,
allowed_hosts, nrpe_user, nrpe_group?

I actaully have only one box, that's running NRPE as a standalone
daemon. U have to add the server IP in the allowed_hosts section (add
the server to /etc/hosts.allow as well).

And u need to restart the daemon on every change.

If u got all the above set up correcty, then i'm affraid i'm out of
ideas... :o(
