I am having major issues making check_radius work and wondering if you could assist.

I currently have my service check sitting in an error 127 out of bounds state.
Running from teminal I get;

./check_radius: error while loading shared libraries: libradiusclient-ng.so.2: cannot open shared object file: No such file or directory

My Command file is following
$USER1$/check_radius -H $ARG1$ -u $ARG2$ -p $ARG3$

My Service check is as follows

arg 1 - host IP
arg 2 User Name
arg 3 password

Please could some one help me get this working.

Nagios Version 3.2.0


I have changed my command file to be the following

./check_radius -H HOST ADDRESS-P 1645 -u user -p password -F /usr/local/etc/radiusclient/radiusclient.conf

Still the same error


i suspect you can change the command as you like but until you solve the missing library problem you won’t have any luck…

error while loading shared libraries: libradiusclient-ng.so.2

How to solve is up to your distributions package manager on debian there is the libradiusclient-ng-dev package which looks like a good candidate.


I am pretty fresh with linux and I am using fedora for my Nagios server.

I will see what I can do with the package however I am having severe difficulties.
