RE: wireless access point

["Myers, Marvin" <MRMyers () anteon com>]

Considering that tools such as Kismet do not rely on any type of broadcasting methods, they actively probe for setups, 
this is a moot point. I have actually had kismet probe a card on a laptop and show me every setup that the card was 
used for. After confronting the user of the card with the results of the probe, they were astonished to see that I not 
only saw the active profile, but three others that were configured for that card. And with Kismet, we were able to 
retrieve the SSID from the CISCO without an association by the one and only client machine that was actually configured 
for that particular AP. Ant we did this with both a Linux box using Kismet, and an XP box using NetStumbler with an 
Netgear WAB501 using WAB511 drivers. Of course the XP box took longer, about two minutes, but this rig by far found 
more AP and held them for a much longer time than the Linux box could.

  It seems to me that the distinction between "detect and
report about a previously-unknown available access point"
and "detect ACTIVE USE of a previously-unknown available
access point" is that the latter is of far less use....
