WLAN

2000-12-14 Thread Teemu Rinta-aho

Hi,

nice to notice that the IETF WLAN is also working here at the
Embassy Suites hotel, which is far (ab. 2 miles) away from the
Sheraton... Is here a secret/uninformed access point or is the range
of WLAN this awesome on this side of the world?-)

BR,
Teemu

So? My network interface card is not.

I just wanted to know if there is an access
point in the hotel or not.

Thank you. That was nice service from Qualcomm, just too
bad there was no information of the wireless coverage
on the meeting web pages.

It wasn't kept secret, though; they had a table set up in the Sheraton
(opposite the social event/LAN card desk) with information.

WLAN at IETF55

2002-11-18 Thread Bob Hinden
We are seeing some of the usual problems with the wireless support at 
IETF55 in Atlanta.  To help mitigate the problems:

1) Make sure you laptop is configured with SSID of IETF55

2) Do not allow your laptop to run in peer-to-peer mode.  Set it to Access
   Point only mode.

We are seeing many nodes running in peer-to-peer mode.  It is essential 
that people not run in peer-to-peer mode.  If you run in peer-to-peer mode 
(even unintentionally) it will disrupt other people and the overall 
wireless network operation.  Many new OS's will fall back to peer-to-peer 
mode by default.  Please make yours does not do this.

See http://www.ietf55.ops.ietf.org/ietf55/NetworkTerminal for more detail 
on OS setup.

Thanks,
Bob (for the NOC team)

p.s.  Later today we will start confiscating the wireless cards of people
  running in peer-to-peer mode

Scheduling in WLAN

2006-01-26 Thread Nejd Zrelli

Hallo!

I am sorry if I am not supposed to send this message in this list.
I have problems in the choose of a real time scheduling algorithm for packets 
in a wireless LAN (802.11b).
My project is the transmission of MPEG4 over WLAN and I'm trying to use a PEP 
(Performance Enhancing Proxy) to do that.

howto WLAN, several subnets

2003-11-20 Thread Alexandru Petrescu
Hi, I was not at the last IETF, and couldn't see live the reportedly bad
workings of WLAN.  I am not going to make suggestions to 58crew since
I'm certain they've already tried lots of configurations.  Just to share
our thoughts on how we make work several
independent/deterministic-behaviour 802.11b subnets:
-for the general public, set the AP's with both an essid and a key, in
 Infrastructure mode (managed).
-for the aodv public, convene to use a different essid and a different
 key and ad-hoc mode.  If the aodv people need several ad-hoc mode
 subnets, just set yet another essid+key; of course all essid's and
 key's must be different each compared to the other.
We have experience with several independent/deterministic-behaviour WLAN
links set up that way.
But, even if this works well with several AP types and cards, there
exist cards out there that only support enc at 128bit while others only
at 64bit, which makes _any_ use of encryption non-portable.  That says,
if ietf crew decides to put a key 64bit then there will be people not
able to connect.  Same if it decides for 128bit.
To me, the whole story is a matter of compatibility, backward
compatibility and forward compatibility between various versions of the
802.11 standards _and_ of their implementations.
It is exactly like with Word versions: it's the same Doc format but not
quite depending on the Windows version too.
I do not think anyone could be blamed of "interfering" with a WLAN
network, most notably because this is unlicensed spectrum; I presume
harmonics of an old microwave oven could be blamed for interference with
the ietf wlan as much as a user not knowing his intel laptop has centrino.

IETF57 Wien WLAN readiness?

2003-07-11 Thread Pekka Savola
Hi,
  
As a lot of folks are coming to IETF57 early, it would be interesting to
know when:
 - the WLAN network is estimated to be operational
 - when/whether it is possible to come to the conf. center
(i.e. as it isn't in a hotel, is it open for IETF'ers e.g. on Saturday
already)

Maybe, helping to find conceptual "wires" to attach to in a
deterministic manner, not necessarily private.  One can not accidentally
attach to such a wire without explicitely setting a key.
My perception is that it brings more problems than it fixes (as you 
stated),
I stated that if crew decides 128bit then all people having 128bit cards
can work ok (and not those with 48bit-exclusively cards).
It does not stop an attacker to set his own linux AP with same key and 
essid ietf, fooling passers by; but at that point that person, if found, 
_can_ be blamed.

and gives a wrong sense of security to boot.
I didn't claim security.

So, if the use of keys gives a false sense of security and moreover
brings overload at the helpdesk, sorry for the proposal, something else
must be used.

Ok, it is true that that behaviour I mentioned above was with Lucent

they call "ad-hoc" IBSS where I is for Infrastructure.
So I guess I was wrong.

So instead of forcing key+essid on the clients, would setting the AP's
MAC address on the clients be a solution?

one could have multiple wireless cards in one machine acting as
access points also, routing between discrete wireless networks.
one could even use managed on one card and ad-hoc or hostap master
mode on the other, to move bandwidth from one network to another all
together, while appearing as a single client.

That may be true in some situations, but should it be tolerated at
the IETF?  Why shouldn't such behavior be prima facie evidence of
insufficent interest or experience in the business of the IETF to be
allowed to participate?

Even in other situations, that sort of behavior is the direct cause
of most of the current security and spam problems on the Internet.
If people would not run "user friendly" products that have designed
and implemented such gross negligence that they execute with full
system privileges any data that happens to come along, then there
would be as many worms, virus, and spam amplifiers in general on the
Internet as there are among UNIX based products.

So a Modest Proposal: Discover which "user friendly" products were
responsible for your troubles and ban everything from their maker(s)
from the next meeting.  Ban any person who breaks that ban at the next
meeting from the following 3 meetings.


(Cue cries about the business of the IETF including educating the masses,
the complete unfairness of holding anyone accuntable for anything,
and the need to be "open to innovation.")

The problem I ran into was seeing a number of IBSSs, most of which
seemed to be using unallocated mac addresses.  Unfortunately I did
not keep any notes of what I acutally did see.

I wished I could have told my 4.8 FreeBSD system to only associate
with one of a list of APs.  I would have given it a list of all of
the real APs and told it to only choose one of those.  Wildcarding
might have also been useful - I would have done (say) two mac address
ranges the real APs were using & ignored the rest.

report on the wlan difficulties in IETF?

2003-11-19 Thread Jari Arkko
Hello,

I wonder if anyone has documented the situation of the IETF wireless
network and analyzed the experienced difficulties? I'd be interested
in looking at the causes of the difficulties. There's a lot of anecdotal
information about the capabilities of the protocols and advice on what
to do on this list. But it would be good to know what was the real cause
of difficulties. Say, its pretty useless to authenticate beacons if
the radios are simply swamped by too many nodes who think they are
access points. Similarly, access control a la 802.1X does not help
if the interferences are caused during or before access authentication
has taken place. Or a correctly operating radio network is no good if
all of its capacity is used by the legitimate, but infected, hosts
for something non-productive. The bottom line is that finger pointing
(staff, ieee, fcc, ourselves...), if useful at all, should come after we
find out what happened.
I suspect the IETF network is pretty the worst case scenario for
current wireless LANs (or can someone point an even more demanding
case?). But what we do today will be done tomorrow by regular users...

Just as a whimsical notion would it be possible to, ah, invite
some of the 802.11* wireless committees to have a colocated meeting
with the IETF at some point in the future?  We could dangle the offer
of "free" wireless networking, plus an offer for them to see what a
real-life, large-scale deployment wireless is really like.  Give them
a chance for them to eat their own dog-food. 

It might be interesting to let the 802.11i folks see what life with

This is not a technical issue. By taking advantage of unlicensed frequencies, 
802.1a/b/g must not cause interference with licensed services, and must accept 
interference from other users, at least in the US. There really is no basis for any 
complaint of lack of service due to interference from any other WLAN or ISM 
device/user.

If you desire a somewhat assured RF medium, explored using licensed frequencies, but 
then you'll have to live with other restraints.

The networks have worked extremely well. Yes, we had problems
this time but I don't think it was your fault. If we find out

Harald, As I said before this was one variant of host that we identified

a number of different configurations will happily join it unless told 
explicitly not to, thereby perpetuating the problem.


It came as a surprise to me when I encountered, this weekend, a public WLAN 
that required people to configure their PCs in ad-hoc mode (they said the 
base station was running in IBSS mode, not BSS - whatever that means).


If the ap where a small linux box without bss implementation such as 
hostap then it would have to run in bss mode (adhoc)


It would be a Really Good Thing if we could have equipment available in 
Dallas to locate a few of these laptops and check out what's *actually* going

Pointing a finger at particular machine in a room with 800 transmitting

I think it's fair to say that the IETF 65 hosting team is aware of the 
issue.

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.


One would hope that none of these adhoc mode laptops have malicious MiM

It's seems unlikely that they are even aware. More than likely however 
some of the people experiencing intermittent connectivty issues are the 
source of a number of the problem hosts.


Good wireless hygiene starts with end users.

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. They could also use Bluetooth, which operates
in the same band, and again they would not be breaking any regulation.

Christian,

This is hardly a matter of FCC regulations or other laws, but rather about
what we can expect from cooperating IETF attendees. Smoking can be
"outlawed" in groups indepently of any local laws that may or may not

Re: Please make sure that you do not run your WLAN in ad hoc mode

2005-11-10 Thread Brett Thorson
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!

Best of luck to the NOC team, and thanks to UofO for the MP3 streams.

Re: Please make sure that you do not run your WLAN in ad hoc mode

2005-11-10 Thread Spencer Dawkins
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.

RE: Please make sure that you do not run your WLAN in ad hoc mode

2005-11-10 Thread Gray, Eric
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 = ietf".

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.

Paradoxically, they have to use *the same* frequencies so that their

On Thu, 10 Nov 2005, Spencer Dawkins wrote:

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 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.


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

2005-11-10 Thread Marshall Eubanks

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.

If people don't know how to turn off ad-hoc mode, will they know how

I think that what we should do is to send the IEEE 801.b/g group a
polite letter pointing out that if our people here at the IETF cannot
figure this stuff out then their less technically astute customers might
be having some trouble as well.

I think that the cause of this 'misconfiguration' is simply people
trying to connect to the network, getting it wrong, twiddling some stuff
at random, trying again and so on. I don't think you are going to stop
that.

I don't believe this is an 802.11 problem.  That group standardizes PHY
and MAC (up to Layer 2) protocols.  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,

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  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.

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

catch any missed the first time around.

Maybe... I know very well how to check my MAC in my primary OS (Linux)
and (I think) in my secondary OS (Win2k). But setting the ad-hoc mode is
buried in a config file in linux, and I still don't know how to check in
Win2k (no, I haven't been running Win2k, and I can see it says "managed"
in Linux iwconfig so that's OK...)

Might it be possible to run a local webserver that can check its ARP
table against the list - it could even offer customized hints how to fix
the problem. Assuming all the APs are on the same network and there's no
routing at that level.  (Of course if you can't get on you won't see the
list, but if it was also a useful place to find updated agendas, wireless
performance stats etc. so that people would go there, in addition to
running the "display in the foyer", they might see that they had been a
problem earlier).

IIRC, MS didn't disable the Messenger service by default until Windows

Insult me, if it makes you feel better.  I stand by my advice.

This is a product usability problem, not a technical shortcoming of the
underlying standards.  My observation was as to the most effective way
to raise the issue.  IEEE 802 doesn't do product testing, but the Wi-Fi

I know. I am attending both the IEEE 802 Plenary meetings and the IETF
meetings for many years. I can witness first hand that the situation is
much worse at the IETF meetings than at the IEEE ones. Practically, the
network is perfect at most IEEE meetings. True, I believe that they are
outsourcing the network deployment and  its maintenance during the
meeting. 

As I will be attending the IEEE 802 meeting next week (in Vancouver, but
at a different hotel) I will be able to report by the end of the week
how it was. Anyway, it hardly can be worse than at the IETF meeting.
During this whole IETF week I could almost never connect during the
meetings. I had to wait for the lunch break when everybody was away, or
to go to my room (at the 7th floor in the tower) to be able to connect
to the IETF wireless network.

Dan,

You must have been on 802.11b.  802.11a was solid from Tuesday 
morning through to the end of the week.  I was having problems on 
Monday with dueling access points but that was fixed by Tuesday morning.

As I will be attending the IEEE 802 meeting next week (in Vancouver, but
at a different hotel) I will be able to report by the end of the week
how it was. Anyway, it hardly can be worse than at the IETF meeting.
During this whole IETF week I could almost never connect during the

to go to my room (at the 7th floor in the tower) to be able to connect
to the IETF wireless network.

Why on Earth wouldn't it be ? I am an IEEE member, and would not take it
kindly not to know how my dues and registration fees are spent. 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.

Three things.

chipsets lack support for ibss mode in 802.11a

8 non-overlapping indoor channels in north america, makes the 802.11a 
radio noise situation more tractable. From a deployment perspective the 
map coloring problem is much easier.


All things being equal an a card has signficantly shorter range range at 
5.8ghz than a b card does at 2412ghz, and more surfaces (airwalls people

RE: Please make sure that you do not run your WLAN in ad hoc mode

2005-11-14 Thread Andrew G. Malis

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.


Cheers,
Andy

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.)

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.

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.

IEEE vs IETF (one more time) was RE: Please make sure that you do not run your WLAN in ad hoc mode

2005-11-12 Thread Brett Thorson
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...

IEEE makes money in all sorts of other ways, including IEEE Dues to say
the least.  I haven't tried very hard, but in 30 seconds of surfing, I can
become a year long member in IEEE $156, attend one meeting $300, and get
one specification [picked one at random] $109.

I think it would be great to get a firm price on how much it would cost to
outsource the network.  We would finally get people to realize the value
they are getting by having hosts and volunteers.

Yes, I know that the IEEE has different sources of funding, and I did
not intent to make any comparison at the level of the two organizations.
I was just providing the information  from the perspective of the fees
that need to be paid by an individual participant in the work of the two
organizations. BTW,  you need not be an IEEE member to take part in the
work of a IEEE 802 Working Group or to attend meetings, you just need to
pay the meeting fee.
