Nagios Support Forum

I just noticed something in your check_nrpe definition. You have:

define command{
command_name check_nrpe
command_line /usr/local/nagios/libexec/check_nrpe -H $HOSTADDRESS -c $ARG1$
}

Change it to:

define command{
command_name check_nrpe
command_line /usr/local/nagios/libexec/check_nrpe -H $HOSTADDRESS$ -c $ARG1$
}

and restart nagios.

Note: You were missing the dollar sign at the end... Let us know if this fixed your problem.

I bet that's it! Unfortunately, now it's Saturday so I won't be able to check it at work until Monday, but since the error messages are suggesting incorrectly specified hosts, it looks like you're correct.
I'll give you a shout on Monday, but in the meantime, thanks again for your valuable support.

Yep - that was it - problem solved!

The Linux server is now giving correct results from within the web interface.

Thanks VERY much for your help - this thread can now be closed.

Glad you were able to find a solution! Closing this per your request.
