Retrieving mac address of remote computer

Hi all. I am currently developing a program that will be able to
retrieve the mac address of an individual computer or a group of
computers on the network.

The idea of the program is that my program is run from one computer
which is attached to the network and then I can select a room number
or type in the computer name the program will then talk to the network
to retrieve the computers MAC address.

However I don't have a clue about how I can get the mac address of a
computer.

Any help in this matter would be highly appreciated.

Thank you

Not sure if this will be of much use, but it might be a starting point
for you.

You have to write the code in C. It is extremely hairy in Windows.. I
started on it once thinking it was a 1 hour project, and abandoned it
and wrote it up as a student project. Then you glue that to Java with
JNI.

See http://mindprod.com/project/macaddress.html
and follow the links for hints on how to proceed.

Use NetworkInterface.getHardwareAddress() for each of the interfaces
returned by NetworkInterface.getNetworkInterfaces().

Note that a host often has multiple network interfaces and
correspondingly many MAC addresses. It's up to you to decide which is
"the" MAC address.
