How to get the MAC address of an ANTENNA on my roof

Well, given that, the first "attempt" at changing the MAC on the PC to that of the bridge on the roof failed but with interesting results.

1. I disconnected the power to the antenna (so that two devices wouldn't have the same MAC address at the same time).
2. I changed the MAC address of the PC to 00-16-B6-32-43-26 (the WISP router on my roof).
3. I pulled the wire of the PC so that only wireless was working, and I connected to the ISPs access point that was beaming to my antenna, but, now is beaming to the PC instead.
4. I directed the web browser on the laptop to http://192.168.3.1 and hit return; the url changed to the following: http://192.168.4.1/login?dst=http%3A%2F%2F192.168.3.1%2Fand a hotspot login came up (which I'm familiar with as the ISP's interface when you connect to it from a MAC address which is not allowed due to their filters).
5. Even more interesting was when I directed the browser to
   formatting link
   and the Firefox browser (with security for unrequested popups) came up blank but with the message:

Request {GET http://192.168.4.1/login?dst=http%3A%2F%2Fwww.google.com%2F

Somewhat easier might be to get a backtrack CD image from t'interweb and burn a CD. Boot a PC off it and bobs your uncle. The hardest bit for me was to find out how to switch round between consoles. That took about two hours since all I knew was I needed more windows. The rest was easy.

aLT-f1, f2 ... f6 -- Default linux consoles. 6 of them.

Mind you you don't seem to mind quite hard:)

With either kismet or backtrack the main issue is to make sure that your wireless card is supported for "monitor mode" with available drivers. There are lists.

This will allow you to sniff the conversation off the air as it transits from your LAN to the internet. The packets will contain the MAC addresses of both your bridge and the remote ISP router.

OOPS. I have just realised that I don't know enough about how wireless works and that the strategy might not work.

Someone will likely correct me if required:-)

In any case backtrack or kismet will let you see the beacons which I believe contain the SSID and certainly the MAC.

Try: Start -> Run Firefox -safe-mode There's also a short cut at: Start -> Programs -> Mozilla Firefox -> Firefox (safe mode). Make sure you do *NOT* have another copy of Firefox running or this will fail.

It's grown to a DVD with 2 GB of programs. That's 500GB of new stuff since the "final" release. The new "Backtrack 4 r1" version just appeared today after Defcon 18. I just downloaded it (it took all day). As before, it's a pain to run as a Live-DVD and works better on a seperate hard disk partition. Do NOT run install.sh unless you plan to install it on your hard disk drive:

I just used v3 since I didn't have any DVDs. Obviously the new one will have more and more-recent drivers. v3 did automagically mount my NTFS partitions (Vista) which allowed me to save files without any messing about despite claiming not to be able to.

If all that is required is the MAC of a single bridge then booting off a CD/DVD is likely to be sufficient:)

E:\backtrack>type step1 modprobe -r iwl3945 # load your driver here modprobe ipwraw iwconfig airmon-ng stop wifi0 ifconfig wifi0 down # mess around in here a bit to set up for my needs airmon-ng start wifi0 airodump-ng wifi0

I think that is enough to see the SSIDs but I forget for now.

You may need to run these in more than one window.

I have the idea that you may need to stop airmon-ng if you want airodump-ng. Again I forget. I had some crashes before I realised that there was a clash somewhere anyway.

Try a (fast) bootable flash drive instead:
