Finding Computer Name from Wireless MAC address?

[Kelemvor]

Editing this post...

At wrk we always have laptops that are setup so their wireless cards are broadcsting as an ad-hoc network. These cause trouble with our actual wireless network at times and we are looking for a way we can track down these people and fix their laptops.

We can get the MAC address from our wireless utility but need to translate that into the computer name so we can figure out whose laptops are setup wrong.

Any utilities or anything anyone knows of that we can use to do this? Maybe something that's a wireless hack program or whatever will be able to trace it back to get the computer name.

Any ideas would be great.

go into your DHCP server and look at the leases. You should find an IP address and a computer name in there. The MAC address is listed under "Unique ID" and on that same line you should see IP address and the computer name

EDIT: hrm, now that i re-read the OP i don't know if you can do this since you said they are just connecting via ad-hoc... what an odd situation

That's exactly the problem. Since they are broadcasting as Ad-Hoc they aren't actually connected to our network. I can connect to them via their ad-hoc connectino but I'm not sure what that gets me as far as getting their computer name and things. Not sure what we can do.

I dont have any experience with WLAN - but maybe a combination of arp -a, find, and finger can help you find the hostname?

arp -a will find give you a hostname to ip adress map. For this situation, do 'arp -a > c:\addresses.txt' (or whatever/wherever you want to name/put it)

find can be used to find the line with the mac address you want to know about, which will also show the ip address found by arp -a. syntax: 'find "string" file' where file would, of course be the filename from the previous command

finger will show you the hostname of the ipadress found with the above commands. syntax: 'finger address'
