It was working with 802.11b without dynamic WEP keying

Ok, I read something about 802.1X, and this involves the EAP protocol 
and a Radius server.
I understand the basic principle of a radius server because I have 
encountered this earlier
(at work). However, I don't know exactly how to set this up.

Right now I am using iwconfig to specify the key.

Where can I find information on setting up a radius server for 802.1X?
