Nagios Support Forum

I have Nagios XI running on 64-bit Centos 5.6. I used the RADIUS config wizard to setup a new monitor for a RADIUS host. However I'm getting this error on all service checks for this monitor:

Return code of 126 is out of bounds - plugin may not be executable

The command associated with the service is:
check_radius_server_adv!-u "adv-radius-svc" -p "*********" -s "************"

However this command doesn't exist in /usr/local/nagios/libexec. (There is a script named check_radius_adv). The current version of the RADIUS config wizard is version 1.3 (latest).

Any ideas on how I can resolve this?

Thanks

What are the permissions on that radius plugin?
