Project Notes

# ./check_radius.pl -h Copyright (C) 2006 Carlos Vicente Checks if a Radius server can authenticate a username/password usage: ./check_radius.pl -H host -u username -p password -s secret [-n nas-ip] [-P port] [-t timeout] Options: -h, --help Print detailed help screen -H, --hostname=ADDRESS Host name or IP Address -P, --port=INTEGER Port number (default: 1812) -u, --username=STRING The user to authenticate -p, --password=STRING Password for autentication (SECURITY RISK) -n, --nas-ip=STRING NAS IP Address (default: 127.0.0.1) -s, --secret=STRING Radius secret -t, --timeout=INTEGER Seconds before connection times out (default: 5) This plugin checks if a username/password can be authenticated against a Radius Server. The password option presents a substantial security issue because the password can be determined by careful watching of the command line in a process listing. This risk is exacerbated because nagios will run the plugin at regular predictable intervals. Please make sure that the password used does not allow access to sensitive system resources, otherwise, a compromise could occur.

Works as needed

Except would have loved to see the response time... and even perf data

It works but dependency has issues

by: batfasturd

Authen perl module has some errors, I fixed it by applying this patch.

Now the plugin works just fine.

Works well - get rid of "-w" to remove warnings!

by: ventz

Works very well.

Similar to what we have written in house.

To everyone that has problems, just take out the "-w" flag in the first line of the script (#!/usr/bin/perl)

This flag is for "with warnings", and as advertised -- it displays warnings about the Module you are using (different issue). Either way, it works fine and you need to return back a single word for Nagios -- thus, getting rid of the warnings makes it nagios compatible.

non functioning

by: struiaj17

It appears to be broken on newer versions of Linux. I get this on Ubuntu 11.10:

Use of uninitialized value $vendor_name in hash element at /usr/share/perl5/Authen/Radius.pm line 431

Non-functional, as far as I can tell

No hint as to what it's looking for or why it is failing.
