I suspected someone running a p2p program and taking up all of the bandwidth, so I fired up ntop to analyze the type of traffic on the network, and just who it was generating it. Lo and behold, someone was running a p2p app, and taking up 1.6Mbit worth of bandwidth. That’s just not fair to the 20 other people on the network, so I decided to boot him from the network. I tried poisoning his arp cache and the default gateway’s cache, but that only works on some wireless access points, apparently not this one. I can’t send an 802.11 deauth message from my OS X box, because the card doesn’t support raw packet injection, so what to do???

I notice that his IP in the ntop interface changed into a name. His windows machine was spewing Netbios packets with his computer name in it. For the sake of his privacy, I’ve changed the name, but let’s say it was “smith-laptop”. So I pick up my cellphone and call the front desk at the hotel and as for Mr. Smith’s room.
