Re: wireless bridge...

"Nick" <renaudfamily@xxxxxxxxxxxx> hath wroth:

I'm more interested in monitoring people who are piggybacking on my network
which I am able to do now with the desktop and the card in promiscuous mode
but won't be able to with the bridge. I think my solution will be to just
throw linux and the wireless card into an old laptop I have laying around
and use that.

That won't do much. If you're gonna run Linux, just fire up arpwatch
and look for any "new" MAC or IP addresses. You don't really need to
do that via wireless. All you really care about is who gets through
your wireless router. If they connect to the access point, but don't
get into your LAN, you probably don't care (unless you're worried
about them using your AP as a non-IP repeater). If you have a
seperate wireless access point and router, then you can just monitor
the traffic between the AP and the router. That will catch any
intruders that appear either on your LAN or go out to the internet.

Another problem with wireless sniffing is that you'll get a awful lot
of garbage. People driving by with their laptops active and set to
connect to anything. Wardrivers with Netstumbler. Door rattlers.
Just plain garbage. Just fire up Kismet for a while and see how much
useless data you collect. Hopefully, you'll have good filters if you
plan to do wireless monitoring. Finding the intruder among all that
junk, errr... data, is not easy.
