Nagios Support Forum

Dear Experts,

I am using nagios core and earlier my predecessor had configured all servers to be monitored by their public-ip. The host was showing down the whole time. i switched the server to private-ip (as address in the hosts cfg file without changing anything in the services section) and added this public ip in nrpe.cfg for allowed host. As a result now i can see the host is up but all the services for this host are now showing down.

i get "CHECK_NRPE: Error - Could not complete SSL handshake. " error which should not happen once i add the ip to be monitored in the nrpe.cfg. Can anyone guide me here, what went wrong?

Do you mean you added the IP of the monitoring server? This is the IP you need in nrpe.cfg

Also - it's possible that you're running nrpe from inetd in which case it's not the nrpe.cfg allowed_hosts parameter that matters but rather only_from in your inetd configuration.
