RE: IP to MAC mapping

I use GFI LANguard Network Security Scanner 3.0 to scan my IP ranges. It will give me things like the computer name, IP address, MAC address, username, OS, shares, open ports, Security Alerts, drives, processes, services, etc... (and it's free)

For extra money, you can do reports, comparisons, etc.. I think version 2.0 is totally free (you'd have to search for it though), and you can do HTML reports, which you could write a script to get the MAC address out of the HTML and compare it to a database.. but that may be the long way around.

It may not be exactly what you're looking for.. but here it is anyway: www.gfi.com

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.

Do you need help?

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,
