Are you sure you have 'check_nrpe' on your new server, and is it in the predetermined location that you've specified?

What happens if you run the check_nrpe from the command line?

Code: Select all

/path/to/your/check_nrpe -H <linux_IP>

I have modified below file & entered Nagios servers separated by comma & restarted the service.

/etc/xined.d/nrpe

The file is:
/etc/xinetd.d/nrpe

And the only_from directive is a list of host address separated by a space (not comma).

Correct this and then restart the xinetd service.

Everthing looks fine. Modified xinetd.d/nrpe file & replaced existing Nagios server with New server, Strange but it worked for me.

Here, am I not able to monitor one server with multiple Nagios servers ?

Sorry I didn't spot this in your original post. only_from on xinetd.conf - no commas, just spaces.
