Nagios 2.0 check_ping not working

Hi everyone,

I’m a little stumped and was wondering if anyone can help me.

I’m using Nagios 2.0. Everything is setup and working so far as I know. The only issue I’m having is my PING and check-host-alive service.

I just get UNKNOWN with this as status information: /bin/ping -n -U -w 10 -c 1 .

The check_ping service works, I was able to run it from cli as well as the ping service within linux itself. This is running on CentOS.

Thank you very much in advance!!!


Try running the command from CLI as user Nagios.

Ok. Thanks!

Thank you! That did the trick. Never thought about that. This issue is now resolved.



But you didn’t say how you fixed it. I will guess that nagios user didn’t have access to the ping command?

Sorry, mah bad. :slight_smile:

Nagios user didn’t have access to use the ping file so I just did

chmod u+s ping

That gave the nagios user access and Nagios was good to go on ping afterwards.
