Monitor RADIUS using default plugin Auth Failure

Post by aastaguy »

Hi All,

Hopefully this is an easy one. I am trying to monitor our RADIUS servers in Nagios XI and trying to use the default check command "check_radius.py" passing -u -p -s on our Radius host and I get "CRITICAL: Authentication failed | 'auth_time'=7.028ms". I can auth using the same details and credentials on our wireless system.

Any thoughts? I thought it may be related to our NPS policy but I'm stuck and not finding much on the web.

Thanks!

Make sure if your username or password has any special chars they are properly escaped, $ ! | ; can get tricky

Also, make sure your Radius server allows connections from your Nagios servers IP address

It's probably the latter, I don't have any special characters in the password.

When you say make sure my Radius server allows connections from nagios are you talking about in the Network Policy Server?

If that is what you are using for the RADIUS server, yes. You need to make sure you aren't limiting the connections to certain servers under the policies section.
