Nagios Support Forum

I'm having difficulties getting our Radius server checks to work properly. I've attempted to set the checks up using the Radius Server wizard, as well as running check_radius_adv and check_radius_ih from the command line of our Nagios host with little success. In XI the result of the check we get is "(No output returned from plugin) Enter Username: unable to resolve radius server: $. abort.", however if I run the check from the command line I get "WARNING: Reply-Msg differs! ('' != 'SBR2CL�������ʚ��*�������
����������������������ʚ��ͦ�') Access ACCEPT. (code = 2) | rtt=0.0029 rttms=2.9109 ".

I can see in the logs on the radius server, that it is sending a response:
09/02/2011 12:37:43 LDAPAUTH: Authentication attempt = 0, user = radiustest, server = s1 - Success
09/02/2011 12:37:43 Sent accept response for user radiustest to client NAGIOSHOST

Anyone have any ideas on what the issue could be?
Thanks!

We've figured this out. It seems that maybe when check_radius_adv was added through the Plugin / Wizard manager it dropped the trailing $ in the comands.cfg file, so we changed this:

command_line $USER1$/check_radius_adv -r $HOSTADDRESS $ARG1$

to this:

command_line $USER1$/check_radius_adv -r $HOSTADDRESS$ $ARG1$

Everything is working as expected now.

Thanks for the update! Glad it's working for you

I just ran into this issue too. After troubleshooting for quite some time, I found this post that saved the day. It seems that the $ is actually missing in the wizard source itself. I corrected it in the radiusserver.cfg file in the tempates folder, rezipped the wizard source, and then reimported the wizard. It then imported and worked as expected.
