Hello, my name is Marcos, I wrote to this list some weeks ago. My problem was the freeradius accounting was working only for "session time" but "input-octets" and "output-octets" attributes weren't being sent by the NAS to the freeradius server. I was using EAP-TLS authentication. The NAS is a Cisco Aironet 1200, it's a WiFi network. Freeradius runs on a Fedora Core4, and it's version 1.0.4. Trying everything, I finally deactivated authentication. Let the network open... and then "input-octets" and "output-octets" started to come included in the accounting packages from the NAS! Now I'll try other EAP methods, but don't think EAP-TLS preventing the packet tracking from working to be normal. I'm doing something worng? It's a Cisco IOS bug? Thanks in advance.
