IP to MAC mapping

["Johan Denoyer" <jdenoy () digital-connexion info>]

Hi,

we are currently looking into illegal usage of a protected network. We are
managing a class C network, and we would like to be able to detect illegal
usage of the network by finding the MAC address of the ip address used and
then checking it against a database.

Now I would like to find a software or a perl scrip that would do the work.
(The budget that we have is 0$, so freeware is likely to be the solution)

I have tried doing searches using google without any luck. If anyone uses
such software, please tell me which one, and where I can find it.

Thanks,


Salutations,
