I have a radius server set up on a server running Ubuntu 11.04. I have configured my switch to use the authentication server's IP (192.168.1.2) for RADIUS / 802.1x authentication, and I created a connection to test connecting from my Mac OSX client.

Here is my radius configuration for the client:

client 192.168.1.0/16 {
  secret = testing123
}

I can successfully authenticate using both 127.0.0.1 (localhost) and 192.168.1.2 (ip of eth1), so I know radius is getting those requests.

I set up a connection to test from my macbook, and my requests are timing out.

Is there a better way to test the radius connection from my macbook? Thanks!

UPDATE: I was able to successfully test on Mac OSX client using RadPerf. This is available as a cross-platform command line tool.
