Hi Matthew

Thanks for your answer, 

I'll then install an up-to-date Linux OS with an up-to-date freeradius version and let you know about the results asap ..

Best regards

That version is very old. You should really upgrade to at least the latest 2.2 version (but v2 is end of life now).

Many ways. It depends on where you want to get the information from, for example. Where does the existing data for MAC auth come from? The users file? A database?

Depends on the above. Could be the users file for the simplest option.

You should send debug output (radiusd -X) for a working example and one that doesn't work at least so we have some idea on what you're doing.
