Hi Thanks for the many many replies. We are a fairly small company (~60 employees) of mostly computer literate (we are a software dev. company) people. And we have a fairly open network policy including BOYD, so keeping a whitelist will be a hassle. Besides, it is easy to eavesdrop on the wifi and sniff whitelisted MAC addresses and then spoof them, so we won't bother doing that. However, we will look into setting up a RADIUS server and authenticate people that way. That should make it possible to match a MAC (even a spoofed MAC) to a user, because noone will be able to route through unless authenticated. Right? An interesting suggestion was to use a directional antenna and a wifi card that can emit radiotap headers. The card in my laptop cannot, so I have ordered a USB card that should be able to do that. The radiotap header can be retrieved using libpcap, and it will provide signal strength with every captured packet, so I can monitor packets from the machine, I am looking for and when my directional antenna points to the machine the signal strength should increase. In theory this will get me the direction from where I am standing. Moving around and pointing the antenna around should give me enough to triangulate and find the machine. In theory! I am sure the RADIUS server will solve my problem, but I will try the antenna+signal strength thinghy too, mostly because it's a fun project. I will provide details to this list when I have them.
