Nagios Support Forum

We have a linux client that will ping to the manager and the manager will ping to it. All services are started and 5666 is open on the firewall. All IP's on both sides are whitelabled. The manager IP is added to the xindetd config file and xinetd is running.

When we run a check_nrpe from the client server it times out
CHECK_NRPE: Socket timeout after 10 second

On the manager side the ping is green but everything else is yellow
CHECK_NRPE: Received 0 bytes from daemon. Check the remote server logs for error messages.

Not sure what to do next... Can someone give us some ideas?

Thanks

From the nagios machine, can you run nmap clientip to test the connectivity?

Do you get a response if you run the following? ./check_nrpe -H clientip -t 60

No it just hangs when we run that command.

nmap from the manager to the client gives this
