Get MAC address??
I am looking for ways to get the MAC address (that is the unique ID of an ethernet card) as an additional way of authenticating an user.
This would be used with the default password scheme (username is no longer needed because of it).
I understand it would not work for everyone, but I feel it could be a nice add-on to current security.
My question is... How can you reliably get the MAC address of a remote user through GNU/Linux systems?
