Logging for Assets and Customers

I am trying to have the ability to log all logins with very specific information so that we can track customer and asset access. I would like this information to be added to the radius mysql in a separate table. This information would include MAC address, last IP, and if possible the last NAS IP. All I really need to know is how to get a script to run with the radius so that it requests that information, or just pulls that information from the connection. Any ideas on how to do this would be extremely helpful. Thank you, Christian RIT Applied Networking and System Admin Rochester Institute of Technology Email: Rahl.Christian@gmail.com
