Here's an article with a little technical info, and a BSD Perl script for wireless sniffing. I guess you need an 802.11 NIC that can be forced into promisc. Don't know which ones those are. http://www.free2air.org/?op=displaystory;sid=2001/4/13/1419/40470 It'd be interesting to do some security testing on your own wireless networks, and see what's really going on. I'd be most concerned in high-density areas like SF, SJ, or apartments/condos. Unlike some posters on Slashdot, I'd be pissed if someone were leeching my broadband access, not to mention the HUGE liability issue should someone hack or warez or Pr0n out via my IP! ("You see, officer, there's this WEP insecurity concerning 802.11b, and when MACs are exposed in the clear...wait!...no, really!...hey, why are you boxing all my stuff up with that red EVIDENCE tape??...Oww, do you have to put these on so tight?")
