It is hard to determine how well it worked because if they fixed it, we didn't know about it (as they blended in to the background infrastructure). Seems to me that most of the people running in ad-hoc mode don't even know it (thus, why bother to read the sheet). Continuing along those lines, sometimes Working Groups have been known to put MAC Addresses on the screens of people in the room (running ad-hoc). I don't know how much success this has either, as the networks still stay up and running. I'll see if I can dig out the "How to turn off ad-hoc mode" sheet from a few meetings back and send it to the upcoming hosts. We have tried to solve some of these problems by taking the MAC addresses of those doing mean things to the net, and stuffing them in a "Penalty Box" so they would come down to the terminal room, and we could track them to a switch port. I actually think this worked pretty darn well. Much of the problem was (wo)man power. We didn't have enough people to run the network, and enough left over for a brute squad. Hopefully with more companies coming back to host the networks (YAY, Thank you!!) we can start doing cool things like this again. 2----Ad-Hoc mode in airports/airplanes So at the talk that started all of this at shmoocon (I haven't reviewed the slides, I'm just going from what I remember from the talk). A few extra notes. The issue was ad-hoc mode on the W-NIC and the goofy 169 address you get from 3927. Microsoft said they would patch this in their next service pack. Patch the fact that you get the auto address or work to disable ad-hoc. Chances are that it would be the auto address. (So then you setup a DHCP server, also mentioned in the talk, and you are back to square 1) MS was there and a rep. said that it was made so you and a bunch of your co-workers could walk outside of the building at lunch with your laptops, and the network still appears to work. I'm guessing he is going off of the fact you would only share networking interests with your buddies, unless they are coming up with some kind of link local grid that has one card acting as a bridge back to to the main network implementation. (Pure speculation) Simple Nomad also discussed during the presentation that he was tinkering with his (recalling from my full brain from the weekend) Palm OS, and this it may also have a problem too. (Add another doc to the IETF packet) Anyway to sum all of this up, some of the people he was playing with were on the plane and unpatched. While I hope & expect (more hope I guess) that the people at an IETF meeting are more saavy than the plane riders, can you imagine walking up to one of these people and handing them a note on how to turn of ad-hoc networking on their wireless lan card? I'd imagine you would get a response similar to handing them a document on how to engage the CAT 3 ILS and land the plane. Simple if you know what you are doing, totally alien if you don't.
