Joel, Thanks - but to answer Eric directly, I was just saying that I was a happy camper for most of the week on 802.11a, in contrast to the problems some people were having on 802.11b. I wasn't making any particular recommendations, but at the next IETF, if your card can support 802.11a, give a try and use whichever mode works best for you.

RE: Please make sure that you do not run your WLAN in ad hoc mode
Are you saying we should use 802.11a because it works better or is somehow isolated from malicious or accidental misuse? No, 802.11a is usually not as good. That's why fewer chipsets bother supporting it, and thus there was less interference for those which do. This is simply a case where in a multiple-standard environment the less prevalent one gains an advantage. (Another case - less common operating systems and software are attacked by fewer viruses.)

It's not necessary to get an exact number or see the contract, just get an approximate value. Look at Ray's recent budget posts. The IETF is largely supported by registration fees, meeting sponsors, and ISOC. That says to me that if we want to have outsourced wireless support (a new charge, since this is now done by volunteers and donations), it will have to be added to registration fees. It seems to me that the IETF community, since it both pays the registration fees, and experiences the wireless access performance, is best situated to determine whether or not this should be outsourced via a surcharge on registration fees. In order to have this discussion meaningfully, someone needs to get a good estimate (not necessarily a quote, but not a guess, either) of what it would cost.

Hardly a fair comparison. It is so evident I'll just sum it up. IETF meetings support the entire organization for the entire year (or at least a third of it). Yeah yeah, blah blah ISOC insurance...

The usability problems with 802.11 networks are in the device drivers, operating systems and configuration applications. It would be more effective to send mail to Microsoft, Apple, et. al. I disagree, I think. IETF, MPEG, large corporate conferences and so on, they all have trouble running large 802.11 networks. They all can run large wired networks. The difference is that even at meetings run by and attended by supposed network experts, it's hard hard hard to get an 802.11 network to run well. That is not right. I do believe that there are (were) some operating systems that switched to ad-hoc mode and made a network if it couldn't find the network you asked to join. (I don't think it was OS X.) That's a mistake. A big big mistake. Guidelines on (a) network naming and (b) frequency selection from the 802.11 group would be useful. For example, maybe you need to do something to claim to be an 'expert' to create an ad-hoc with a 'plain' name; otherwise your ad-hoc network would be (for example) prefixed by * or something. And maybe OS's could diagnose frequency problems (there are several base stations in here all on channel XX and they are interfering with each other or whatever). Dammit, a FAQ on http://grouper.ieee.org/groups would be a good start. I've been at a meeting where a respected network equipment provider provided the network. Because the base stations had an artificial limit of 10 IP addresses for their NAT/DHCP, he setup 3 of them in the room, next to each other, on the same channel and SSID. Result -- they are all in very low-power mode, interfering like hell, and the users if they get a signal can't choose from which box and so it doesn't actually spread the load. Finally, it's clear that at least some base stations get hopelessly confused (sometimes I have even resorted to the technical term wedged) when there is an ad-hoc in range with the same SSID. Some testing and robustness guidelines from the 802.11 group would also help. -- David Singer Apple Computer/QuickTime ___ Ietf mailing list Ietf@ietf.org https://www1.ietf.org/mailman/listinfo/ietf

Re: Please make sure that you do not run your WLAN in ad hoc mode
I think we can make a pretty good guess as to the list, although maybe not the relative positions. I think that from now on registration packets should include a sheet about how to tell if you are running an ad hoc network for a variety of OS flavors, and have sent a detailed suggestion to that effect to the IAOC. There should be sufficient resources in the IETF community to do this for even the fairly old flavors; a simple note at the bottom saying that if your OS is not included, email [EMAIL PROTECTED], should catch any missed the first time around.

Re: Re: Please make sure that you do not run your WLAN in ad hoc mode
Joel, You can,(we've done it in the past) but since they're not actually connected to the network when they're misbehaving it doesn't buy you much until they fix their card, sleep their laptop, or reboot. Having done some testing with various Operating systems wireless implmentations, I think we can say with some degree of confidence the instigating hosts are generally windows 2000 machines, it could be time to upgrade because the winxp ndis wireless drivers won't do this without some coaxing. Or, I'd be happy to hand out knoppix cd's to anyone who wants one. Do you have a sense if it is Win 2000 or if it is related to any specific wlan driver software? I'd think a basic list of cards / sw that often misbehave would be a good thing. That way, when we see a few adhoc devices in a meeting, the chairs could more specifically tell people running OS X / card Y to check their devices.

Unlicensed spectrum, like the 2.4GHz and 5GHz bands used by Wi-Fi, can be used by anybody. If I remember correctly, there was an FCC ruling on a similar case, where an airport wanted to get airlines to stop using their own Wi-Fi devices, uncoordinated with the airport. The FCC essentially ruled that as it is an open band, landlords and other facility managers can't prevent people from using the waveband. I did not check the laws of Canada, but in the US at least the IETF cannot force people to stop using ad hoc. If two participants want to set up an ad hoc network and exchange data between themselves, there is hardly anything the NOC can say.

Re: Please make sure that you do not run your WLAN in ad hoc mode
It is hard to be very strict at an IETF meeting. We first started running Penalty Boxes at one of the Minneapolis IETF meetings. Why did we do it? Because we had time. We got the network working reasonably well and could dedicate our time to ... Fighting Evil. So we setup the penalty box, and we put people in there. We found a mean MAC addr, set it all up, and then came the question.. Do you really want to do this? That was a hard call to make honestly. There were a lot of smart people in the NOC (There always are). Even with all that intelligence, you could feel the tension in the room as we put 'em in there. Why? Well we have enough people bashing the NOC crew all the time. Now we were purposefully messing with people. How would you like to be the person that accidentally put the IETF-Chair in the penalty box? So we put quite a few people in there, and we caught at least one (Thanks Joel). Was the guy actually doing malicious things. We think so. Did he act like he didn't know what was going on? Yep. Did he unplug his computer as soon as we found him, yep. It was all very odd. Somewhat rewarding, but still weird. Ok, let's sum this up. 1. The people who are running in ad-hoc mode, if you look at a few of those nets, you will see multiple MAC addresses for the same network. Look closer and some of the OUI's look downright spooky. You could be chasing them for quite some time. 2. As someone else pointed out, they would only feel the effects of your efforts if they connect back to the IETF network. Do you think they will? 3. One of the ways we caught the person in Minneapolis was because of the goo coming out of their WLAN card (scanning), we shut them off, and then saw the same goo coming out of their wired port. Doesn't apply to well to wireless ad-hoc. I bet you can catch some of the people, but in the end it is probably a pretty low priority compared with tuning all your APs so the wireless coverage at the plenary doesn't crash into itself. I think training would be great. The only problem is that either they are doing it to be mean, or they have no idea they are doing it in the first place and skim over the documentation asking them to check their config as if it were a note well. I'm all for the Penalty Box, I thought it was cool. But looking at that list of Ad-HOC nets and MAC addresses. Wow, that's a lot!

RE: Please make sure that you do not run your WLAN in ad hoc mode
The problem stems (I hope) from people not knowing that they have their PC in Ad-Hoc mode when they specify that they want to connect to network ietf64. So the answer should be that ad hoc mode with SSID = ietfXX. However, people wanting to have a private ad hoc network ought to look at the frequencies being used by local base-stations so that their signals do not interfere with people using the infrastructure mode. -- Eric -- -Original Message- -- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] -- On Behalf Of Spencer Dawkins -- Sent: Thursday, November 10, 2005 5:13 PM -- To: ietf@ietf.org -- Subject: Re: Please make sure that you do not run your WLAN -- in ad hoc mode -- -- Just to be clear - is the problem ad hoc mode or ad hoc -- mode with SSID ietf? -- -- The last time we were in Minneapolis, Dean Willis noticed -- that the wireless projector controls in the conference -- rooms used 802.11b ad hoc ... in an increasingly IP-deviced -- world, if the problem is ad hoc mode, we are going to die -- at an increasing rate over time. -- -- Spencer -- -- -- ___ -- Ietf mailing list -- Ietf@ietf.org -- https://www1.ietf.org/mailman/listinfo/ietf -- ___ Ietf mailing list Ietf@ietf.org https://www1.ietf.org/mailman/listinfo/ietf

On Thu, 10 Nov 2005, Spencer Dawkins wrote: Just to be clear - is the problem ad hoc mode or ad hoc mode with SSID ietf? The problem basically works out to something like this... A host with the magic settings, or defaults comes up, for whatever reason it can't associate with an accesspoint, so it says hey: I'll flop over to bss mode and become an adhoc node. Now another host comes along as says, hey the strongest network I see is this adhoc network, so I'll join that. So you have a bunch of hosts participating in this bss network, and because they're not being managed by an ibss node (an ap) their beacons and any traffic they send clobber traffic from the ap's around them making the situation worse. Now, the ibss ap's have their power output turned down so that they don't clobber each other, because a certain ap density is needed support all the users on this network. So if the ap is transmitting at 15mw and you have a laptop with 100mw card which One wins? The problem with a node that's decided to become adhoc is when would it decide to change back? It won't. Probably when your fiddle with your card settings, reset the card, sleep the laptop or reboot, that will be enough. Certain implentations, eg macosX 10.1 would switch to an adhoc network with the same ssid as the mananged netowrk even if they were configured only to connect to managed networks. So, good hygiene is: Configure your laptop to stick to the ssid ietf64 Configure you card to only operate in managed, ibss or accesspoint networks. If you have a card with selectable output power (like an old cisco, prism 2, or atheros) pick something below 100mw like 15mw or or 30mw. if you have a card with a density setting like and old lucent orinoco card, set it to high. if you have 802.11a support use it.

The number of devices in your pocket and in the environment with radios does indeed increase over time. Couple that with the challenges of working in a new space, with days or hours of setup time, no decent simulation tools for a room with 100 tons of meat and 800 radio's in it. and host implementations of widely varying quality, and you have a challenging dynamic environment that should make every host scared.

Re: Please make sure that you do not run your WLAN in ad hoc mode
I honestly think that there is something more than that. I have seen dozens of instances of IETF64 as an ad hoc network. (I see 6 sitting here in the plenary.) Unless there is someone with a perverse sense of humor spoofing me, I suspect that people are trying to join to the ietf64 network and getting it wrong, both in captialization, and in configuration. (Oddly, I have yet to see ietf64 as an ad hoc network.) Of course, when the network availability is poor, mis-configuration doesn't stand out like it does when everyone else in on the network except you.

The survey we did is about two years old now, but at the time a fair number of the win2k drivers would produce this behavior. Basically to much default auto-configuration. having the wireless card be mananged by windows (winxp) went a long way towards solving this issue for windows machines. It is still possible to hose yourself if you try. It think it would be a fairly serious mistake to add to the workload of the working-group chairs by making them front-line tech support for the wireless network. The current exhortation towards checking for your laptop being in adhoc mode is well meaning, but a lot like throwing salt over the shoulder. If we want to characterize certain users or applications as mission critical providing additional wired ports in meeting rooms to support them seems reasonable. Including large numbers of wired ports seems like madness however.
