Understand that most OSes (perhaps not windows, but I wouldn't put it past having a registry key somewhere) allow you to set the MAC address to anything you want it to be... So all you would find would be casual crashers...
Set up a small Linux or *nix box and use arpwatch - it's a daemon that monitors the network and can email you with changes. -----Burton -----Original Message----- From: Johan Denoyer [mailto:[EMAIL PROTECTED]] Sent: Wednesday, November 20, 2002 11:50 AM To: [EMAIL PROTECTED] Subject: IP to MAC mapping 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, Johan Denoyer [EMAIL PROTECTED] Digital Connexion http://www.digital-connexion.info PGP : 0x57A6727B
