RE: Alert when MAC address connects to network

["Filipe Joel de Almeida" <Filipe.Joel () netcabo pt>]

I use a software to monitor my network and detect if an unauthorized MAC
connects.

It's designed for wireless connections, but works the same in wired.

If you add all the MACS you have except the one that was stolen, it should
detect when it connects.

The link where I got the software from is:

I hope this helps you.

I don't know if there is a utility to notify you....maybe snort, but keep in
mind the mac address can be spoofed and chances are it's gone for good.

        Hi all!
        
        We've got a problem in our school building. There are a lot of
laptops
        in various classrooms and now there is one that has been stolen.
We'd
        really like to be alerted when this machine connects again to the
        network and like to get our hands on the one using it now.
        
        Is there a possibility to get alarmed, when a certain MAC address
        connects to our network? Any other recommendations to our problem?
        
        Many thanks in advance,
        Magnus
