I've done the following to install and test freeradius on Scientific Linux el6_4.  The server is one I use for testing and also has Splunk installed on it.  No issues with Splunk and the ip address have been found as I've gotten logs from other test equipment into Splunk - I installed the freeradius-2.1.12-4.el6_3.x86_64 and then the utilities freeradius-utils-2.1.12-4.el6_3.x86_64.rpm to get the client (radtest).  - I made a change to the users file to add the testing Cleartext-Password := "password".  My hosts file indicates both lo and the ip address for the server.  I can ping the server without issues.  - After I added the line to the users file, I started radiusd -X >debug.txt   I then opened another terminal window on the same server and performed the - radtest testing password 127.0.0.1 0 testing123.  - I received an error indicating failed to find ip address for linux-mail.amber.net followed by nothing to do.  - I looked at clients.conf and change the ip address from 127.0.0.1 to my ip address and added hostname.  The results remained the same so I've reverted to original config for this. Each time I made any changes I restarted radiusd by killing the process and restarting.  I could not service radiusd stop or radiusd stop to stop the application.  I tried pasting the debug txt into the debug form on the other site and received a 405Forbidden when I accepted the policy. I've put my debug from testing with just the change to the users file below.  Would appreciate any insight into what could be wrong.
