AAA configuration

Hi all,

I installed FreeRADIUS on Ubuntu, configured the database (mysql), performed radtest from the localhost and NTradPing from a remote WIN machine. Now I want to make this process automatic, so that every connection/disconnection to/from the Internet put a record in *radacct* table. I realized that I should configure my AP and I found some guides here: http://wiki.freeradius.org/vendor/Cisco

I have 2 specific questions:

1. How and where exactly I can run the AAA configuration commands? 2. What if my NAS is not of Cisco family? Does that make any difference?

Any help will be really appreciated.

Thanks, Anisa
