airodump-ng: channel handling is broken.

[anonymous]

airodump-ng doesn't work well with drivers from compat-wireless (or wireless-testing).

No matter if you use one vif or more than one, with the command:

airodump-ng -c <channel number> <monitor interface>

you got something like:

 CH  9 ][ Elapsed: 24 s ][ 2010-05-22 03:15 ][ fixed channel mon0: -1

...

In the example airodump-ng was launched with -c 9 but airodump-ng says channel -1, and with aireplay-ng you got something like this:

03:15:37  mon0 is on channel -1, but the AP uses channel 9

It could be related with the new channel handling:

I tried compat-wireless 2.6.34 on a 2.6.34rc6 (Backtrack 4 r1) but I can't reproduce your bug (ath5k and rtl8187).

Could you describe me the different steps and what distro you used as well as the name of the driver you used. Did you kill all network managers?

[misterx]

It seems to fail with that version: ​http://wireless.kernel.org/download/compat-wireless-2.6/compat-wireless-2010-05-22.tar.bz2

[anonymous]

There is no problem if you use the drivers that come in a vanilla kernel (2.6.34 and below).

There is no problem if you use the drivers that come in the _stable_ branch of compat-wireless.

But there are at least two branch of compat-wireless and the issue appears if you use the "bleeding edge" of compat-wireless.

wireless.kernel.org/en/users/Download

wireless.kernel.org/en/users/Download#Compat-wireless_release_types

The issue can be reproduced with a tarball like this:

wireless.kernel.org/download/compat-wireless-2.6/compat-wireless-2010-05-22.tar.bz2



Download / compile / install / load drivers and the steps are these:

With mac80211-based drivers you have by default a interface wlan0 in managed mode and down.

1) Create a monitor interface with airmon-ng

# airmon-ng start wlan0

now you have two interfaces: wlan0 (mode managed and down) and mon0 (mode monitor and up)

2) Launch airodump-ng in a fixed channel (i.e. channel 6)

# airodump-ng -c 6 mon0

You get something like this:

 CH  6 ][ Elapsed: 24 s ][ 2010-05-23 19:21 ][ fixed channel mon0: -1
...

and if you use aireplay-ng you get something like this:

...
19:21:36  Waiting for beacon frame (BSSID: XX:XX:XX:XX:XX:XX) on channel -1
19:21:37  mon0 is on channel -1, but the AP uses channel 6

The channel hopping with airodump-ng is working well the issue appears when you fixed a channel.

I can confirm the issue with drivers rt2x00 (rt73usb, rt2500pci), zd1211rw and ath5k (may be all mac80211-based drivers are affected).

Same problem in ubuntu 10/10 alpha 2 with the following cards:
intel 3945
atheros ar928x (ath9k)

I use the kernel and aircrack-ng in the official repositories of ubuntu.
Linux 2.6.35-6
aircrack-ng 1.1

[misterx]

There are 2 possibilities:

• In the driver: Improve patch "Path for fixed channel issue in aircrack-ng suite [V2]" so that it can be included in linux-wireless (see entire thread: ​http://marc.info/?t=127476414900004&r=1&w=4 ).
• In OSdep by using the channel from the radiotap headers in packets.

[Roadkill]

Backtrack 4 with Kernel 2.6.35 monX fixed channel is still -1

[anonymous]

That means that the problem has arrived to vanilla kernels. Now all branches are affected (wireless-testing, wireless-next-2.6, wireless-2.6, linux-next, linux-2.6, ...).

[anonymous]

BackTrack 4 R1 with a RT2870/3070 chipset adapter and compat-wireless I have this issue as well:/

[weaknetlabs]

compiling new kernel for distro, i can confirm the failure above. When I use

airmon-ng start <dev> 

I get

[: <integer here>: x: unexpected operator

I have tried a few patches from the above links all on clean builds/tarballs and channel still says "fixed -1"

reverting back to 2.6.34 for functionality.

[Klemens]

I use Backtrack 4. I installed new kernel 2.6.35 and now i have always "fixed channel mon0: -1"

[weaknetlabs]

I followed the directions from Roadkill and it saved my development! I am back on track now, The only things i did differently was I used the fakeroot/make-kpkg (old fashioned Debian way) and there were a few typos, like "/usr/usr/src/linux-2.6.35" and at one point he called it a 2.5.35 kernel! Other than that, i am back on track with development. Thank you. The only issue I have now is with airmon-ng. I still get "[: 374: x: unexpected operator" when running, yet it works and Airodump-ng can channel hop and lock onto a channel using ath5k.
Thanks again!

You need to download compat-wireless, the file is there. find /net/wireless directory within the compat-wireless directory, move the patch file there. and patch -Np3 -i <patch file>

Ubuntu 10.10, kernel 2.6.35-24.42, Acer Aspire AO751h netbook, ath5k module, AR5001. Thank you very much for the instructions, everything seems to work, injection and channel handling. I tried to get the first patch, but received a 404 error so i skipped it. Anyways, seems to work fine without it.

[quinametin]

I've installed the patches but after that my bcm4322 stopped working :(
"insmod wl
Unknown symbol lib80211_get_crypto_ops (err -22)
FATAL: Error inserting wl (/lib/modules/2.6.35-22-generic/updates/dkms/wl.ko): Invalid argument."

After uninstalling compat-wireless I can use bcm4322 but the problem of -1 channel remains...
Any ideas?
Thanks

[XayOn]

quinametin, have you tried with older compat-wireless version? I've spotted some problems with recent ones.

i cant figure this out im running a 32 bit ubuntu 10.10 (2.6.35-24-generic) netbook remix on a acer aspire one d255 my wlan cards (atheros 9271 & Intel 4965/5xxx) bolth work and inject but bolth get stuck on chan-1 i installed the compat wireless backports (backports-modules-compat-wireless-2.6.36-generic) through the software center using aircranck-ng 1.1 kinda new to linux and aircrack but i would like to know if i could use the patches above and if not what should i do ?any help greatly appreciated

[ras82x@…]

Same issue, 'fixed channel: -1' on my Lenovo G555 (ath9k), with experimental 2.6.36 and 2.6.37 Debian kernels, iwconfig also fails to change mon0 interface's channel/frequency.
With stable kernel 2.6.32 all works fine.
Going to try suggested patches, will reply afterwards.

[fercerpav@…]

Attached was an aireplay-ng patch that allows to ignore the mismatch
when kernel is unable to report the used channel.

[jwtjoker1984@…]

sweet now i just need to figure out how to use it

So now that solutions have been proposed, is this bug going to be fixed

1. In aircrack? If so, which version?
2. In the main linux kernel? If so, which version?
3. In distros?
4. Or will we have to continue to patch things forever?

After upgrading to latest Ubuntu 10.10 i got the "channel fixed -1" error.

helped me out and worked on both Intel 4965/5xxx and RTL8187.

Important note:
If i start airplay-ng BEFORE i started airodump-ng, the "channel fixed -1" is still there.

Solution:
First i started "airodmp-ng -c <channel>", now i can use "aireplay-ng"!

im using a white macbook with os ubuntu everything works until the fixed channel airport doesnt work so i bought a usb wifi adapter a tl-wn422g from tp-link and it works but it goes form wlan0 to mon0 and from the channel i choose it goes to fixed channel -1 im sorry to ask ive been looking for 2 days now is this normal? are there any solutions? please help.

[anonymous]

i'm new to the linux world, and i just can't figure out how to get the channel to change, i read through the whole topic and just lost it, hehe, if someone could actually tell me what i should do specifically, how is something i'll figure out with time, but what is the problem

[Tractor]

Hi, well i just discovered something with a big help of aircrack-ng community.
If you have got this silly bug with fixed channel -1 u can try maybe subversion of aircrack-ng ?
How to get it ? simple .....
uninstall aircrack-ng from ur system.
You will need such libraries :
subversion
gcc
openssl-devl
(depends which distro are you using the libraries name may vary)
Ok you got all ur libraries ready than type this in terminal :

svn co hxxp://trac.aircrack-ng.org/svn/trunk aircrack-ng
cd aircrack-ng
make
make install

after installation completed you can update airodump-ng, the proper way to do it will be displayed at the end of installation.
And now when you wanna use aireplay-ng just type command as usual and at the end add : --ignore-negative-one

should do the trick.
some info here :
hxxp://trac.aircrack-ng.org/wiki/Sources
hxxp://www.aircrack-ng.org/doku.php#download

TBH i have just checked if aireplay-ng does work, and it does,
I havent checked injections cracking and etc.
I heard there is problem with handshake, but havent tested it yet
Anyway good luck coz u will need it :)) (in links xx change to tt)

[Tractor]

svn co http :trac.aircrack-ng.org/svn/trunk aircrack-ng
cd aircrack-ng
make
make install

[ProfesorAlga]

Replying to Tractor:

svn co http :trac.aircrack-ng.org/svn/trunk aircrack-ng
cd aircrack-ng
make
make install

Mmmh... sorry, it doesn't worked for me. Your guide is correct, i followed it, but airodump showed the damned -1... I had to patch compat wireless drivers ... Thanx anyway !

[Tractor]

Hi there,
Yea if you will install latest subversion of aircrack-ng, you will still get "fixed channel: -1" in airodump-ng BUT ignore it. You are still able to catch handshake and etc.
But to check the handshake you will have to type :
aircrack-ng *cap

*.cap = your cap file saved by airodump when tried to catch handshake.

It is 100% working solution :) but you can still patch compat-wireless drivers.
This guid is more for ppl who got proper wireless drivers with they kernel.
Example : OpenSUSE 11.3 & 11.4 with Intel3945.

Best Regards,
Tractor

[anonymous]

Experiencing the same problem here with RaLink? RT2860 card on Ubuntu 10.10 - airodump seems to set channel and capture fine, but records the "fixed channel -1" error and renders aireplay unusable as described. Airodump in scanning mode triggers no such error but aireplay seems to whether or not the channel has been specified elsewhere (airmon start or airodump)...

[leonardo,guilherme@…]

From iwconfig manual, section "freq/channel"

" When using Managed mode, most often the Access Point dictates the channel and the driver may refuse the setting of the

frequency. In Ad-Hoc mode, the frequency setting may only be used at initial cell creation, and may be ignored when join‐
ing an existing cell."

Setting the card to monitor mode before starting airmon-ng fixes, at least for intel cards.

[Clovis]

Anyone can post a complete step how to do this?
I am totally confuse with all these discussions.

1. Download the compat-wireless source code (hxxp://wireless.kernel.org/download/compat-wireless-2.6/compat-wireless-2010-10-16.tar.bz2) , and extract it to a cleanly made directory.
2. Download this patch (hxxp://patches.aircrack-ng.org/channel-negative-one-maxim.patch)

what else should i do?
Please help me by posting the commands I should use.

Thanks a lot.

I'm trying to use that at FC14 with kernel (2.6.35.13-92.fc14.x86_64) but doesn't work, I already tested compat-wireless-2.6.39 , but still not work.

[SevanEl@…]

Having Ubuntu 11.04 32-bit with 2.6.38-8-generic kernel on my SONY VAIO SZ220, which has a Intel Corporation PRO/Wireless 3945ABG network adapter, I experience the same negative one problem.

Using iwl3945 as driver, I did as fallows, to eliminate any possible interference, as suggested by previous posts:

sudo service network-manager stop
sudo service avahi-daemon stop
sudo service upstart-udev-bridge stop
sudo pkill wpa_supplicant
	
sudo ifconfig wlan0 up
sudo iwconfig wlan0 Channel $CHANNEL
sudo ifconfig wlan0 down
sudo iwconfig wlan0 Mode Monitor

sudo airmon-ng start wlan0 $CHANNEL

sudo aireplay-ng --arpreplay -b $AP_BSSID -h $SOURCE_MAC -x 50 mon0

sudo airodump-ng --channel $CHANNEL --write data  mon0

But, I keep getting "mon0 is on channel -1, but the AP uses channel 6" from aireplay-ng and "fixed channel mon0: -1" from airodump-ng. I have to add that just by stopping the network-manager service before calling airmon-ng, and in spite the airodump-ng's negative one fixed channel report, airodump-ng seems to work on my specified channel, since the output for airodump-ng is showing APs on the specified channel only. It even works the same way without specifying the channel on airmon-ng call, but none of the above precautions affect on the aireplay-ng's exit with error.

BTW, I am using aircrack-ng version 1:1.1-1.1.

PS: Going to check other suggestions, and I'll keep you posted.

[raubtaube]

Same problem here with Ubuntu 11.04 32-bit with 2.6.38-10-generic kernel. Using an atheros chip with ath9k driver. Also tried to install channel-negative-one-maxim.patch but make stopped with errors.

[Preston Lee]

Another issue confirmation for Ubuntu 11.04 x64 with a ra73usb. I can't believe this issue has gone unresolved for the so long. Perhaps it would be time to bring up an upstream discussion again? This bug makes a long of core aircrack use cases undoable.

[anonymous]

Care to update us on this issue misterx?

[anonymous]

Still unchanged ?

[Karit]

I had the same problem with the chanel -1, but I followed the instuctions of Tractor and aircrack-ng is working out of the box right now!

I have PCLinuxOS with kernel 2.6.38.8 and my wireless network is an Atheros AR242x / AR542x.

I think that the key for solving this problem is putting the --ignore-negative-one argument every time you use the aireplay-ng command.

PD: I didn't apply any patch!

• Use the option '--ignore-neagtive-one', e.g.:

sudo aireplay-ng -3 -b BSSID -h MAC --ignore-negative-one mon0

(of course, you must replace "BSSID", "MAC" and "mon0" for the convenient for you).

This is the only that work for me. (Note: previously, I uninstall aircrack-ng with Synaptic.)

Everyone,

Don't keep repeating "I also have this problem with aircrack-ng 1.1". The developers know that, they know the cause and they have a workaround. It will be fixed in the next release.

In the meanwhile, either use trunk or 1.1 with one of the patches attached here. Do not patch compat-wireless. It is not needed or recommended.

Well, patching compat-wireless makes it easier. Plus you have up to date drivers.

• Use the option '--ignore-neagtive-one', e.g.:

sudo aireplay-ng -3 -b BSSID -h MAC --ignore-negative-one mon0

(of course, you must replace "BSSID", "MAC" and "mon0" for the convenient for you).

This is the only that work for me. (Note: previously, I uninstall aircrack-ng with Synaptic.)

This worked for me.
Now i have to make my brcm 4313 to inject!
Thanks

Same Issue with Ubuntu 11.10 64bit, Intel 4965 AGN.

Compiling latest stable Compat-Wireless w/ patches always yields no connections.

Nuts.

I use Ubuntu 11.04 64 bits, Atheros ath9k, and aircrack-ng from the Ubuntu repos. The only that work for me is the next:

• Install subversion (from Synaptic, for example, or with "sudo apt-get install")

• Install libssl-dev (and eventually, any package needed)

• Get aircrack-ng for subversion:

svn co http: trac.aircrack-ng.org/svn/trunk aircrack-ng

• And compile and install:

cd aircrack-ng

make

make install (or: "sudo make install", if "make install" don't work for you)

• Use the option '--ignore-neagtive-one', e.g.:

sudo aireplay-ng -3 -b BSSID -h MAC --ignore-negative-one mon0

(of course, you must replace "BSSID", "MAC" and "mon0" for the convenient for you).

This is the only that work for me. (Note: previously, I uninstall aircrack-ng with Synaptic.)

So this way kind off worked for me. It works with the airolib-ng commands but when im trying the aireplay-ng commands, it always ends up putting the -1 channel anyway.
(i am putting the --ignore-negative-one)
Running Ubuntu 11.10 x64 with ath9k drivers.

Worked for me, Ubuntu 11.10 ath9k, thx alot!!!

I have a workaround. I am using Arch Linux kernel 3.1.9 with ath5k drivers on Atheros AR242x/AR542x wireless network adapter. (Basically I installed Arch on an Acer Aspire One ZG5 and went to town.) I found that after turning of all wireless daemons and applications -

airmon-ng check

I can force the wireless card to the desired channel -

iwconfig wlan0 channel 6

Then run

airmon-ng start wlan0;
airmon-ng stop mon0;
airmon-ng stop wlan0

Thats right. Start and then completely stop monitor mode. From here, follow the normal steps using wlan0 as the interface.

--terminal 1--
airodump-ng -c 6 --bssid <target mac> -w <output file> wlan0
--terminal 2--
aireplay-ng -1 5 -a <target mac> wlan0
aireplay-ng -3 -b <target mac> wlan0
--terminal 3--
aircrack-ng output*.cap

if you check the wireless interface at this point, it will actually be in monitor mode. to put it back in managed, kill it again

airmon-ng stop wlan0

Hope this helps.

I can't confirm this works but I still think patching is easier (or use the very latest kernel where it should be fixed).

[Colombian]

Ok, finally, the answer after 21 months is....
I'm sick of this, trying and trying but I wil do it tomorrow, I m tired

Shouldn't it be fixed in compat-wireless-3.3 ? (I still have not tested it myself, got it from ZC)

Build lastest compat-wireless and check it out.

Arch kernel 3.2.13 iwlwifi 5100 here, still an issue

[Leox]

In Ubuntu 12.04, can't set the channel.
So also got this problem

Interface Chipset Driver
wlan0 Unknown rtl8192se - [phy0]

[wifi007@…]

I think that ubuntu 12.04 don't supports "aircrack-ng" ...
I'm beginner in Linux and I use ubuntu 11.10, my PC Dell inspiron 1750 32-bit
I soon installed "aircrack-ng" network chipset-broadcom ; driver-b43 - [phy0]
I have a same problem with "fixed channel mon0: -1" can somebody help me, how to corrects this problem...?? thank you ...

[anonymous]

in Ubuntu 12.04 with Atheros still an issue.

[anonymous]

Confirmed that in Ubuntu 12.04 is still a issue. Tried with Atheros, Realtek and Ralink chipsets.

[Maurich]

I have the atk9h driver on a USB card and my pc wireless is Broadcom

wlan1 Atheros ath9k - [phy1]
wlan0 Unknown brcmsmac - [phy0]

and i have the same problem I've edit the common.mak file in the Aircrack dir and still nothing. Its weird cuz i use the ath9k not the other one and that one is always off so. any suggestions. BTW
Ubuntu 12.04

[anonymous]

Confirming bug in 12.04 ubuntu.....

[anonymous]

and linux mint 13

[anonymous]

Also suffering from this bug on Ubuntu 12.04.1 using the ath9k driver, executing
airodump-ng -c 10 --bssid 00:0E:8E:30:9E:53 -w dump wlanMoni
leads to "fixed channel wlanMoni: -1" in the upper right corner.

However this workaround seems to work to set the channel to 10:

[clopez]

Please, someone running Ubuntu 12.04 with this bug.

• Download latest svn version:

  svn co http://trac.aircrack-ng.org/svn/trunk/ aircrack-ng
  cd aircrack-ng
  

• Install build dependencies

  sudo apt-get install libnl-3-dev zlib1g-dev libpcap0.8-dev libssl-dev libnl-genl-3-dev
  

• Compile with libnl=true

  make libnl=true
  

• And test it

  sudo ./src/airodump-ng [...]
  sudo ./src/aireplay-ng [...]
  

And report here if the problem got solved when compiling aircrack with libnl=true from latest SVN

[anonymous]

checked out latest svn version, compiled with libnl=true, problem persists, tested on Linux Mint 13

Don't exit when the AP and our interface are on different channels

[clopez]

Ok. I think that we should print a warning and continue as if nothing happened. See the above patch.

[PATCH] Don't exit when the AP and our interface are on different channels:

• This workarounds bug #742
  • At least people can use it as expected. I tested that it works despite aircrack-ng thinking that the interface is on channel -1
• Its also useful when you want to attack APs that are near to the channel on wich your interface is tunned.
  • Is a fact that if you are in channel, lets say 9, you can also attack clients on channel 8 or 10 (less successfully than if you were on such channels, but works)
  • The use case is: I'm attacking AP on channel 9, but its taking a long time, so in the meanwhile there is another AP on channel 8 that I would wish to attack but I only have one wireless card, So... let the user just try it!! Printing a warning is enough. Not need to force an exit.

[misterx]

Problem 1: Channel -1

There is an option called --ignore-negative-one which does exactly that thing.

Problem 2: Attack AP from a different channel

Not a good idea, it is much less effective. Plus, it will just bring more people because they can't crack their AP and they're on the wrong channel.

[Anon]

clopez - I am using ubuntu 12.04 and I wanted to report back here that the problem has somewhat been fixed. I was using the latest version of aircrack-ng from aircrack-ng.org. The svn install with make libnl=true seems to work. I still get the -1 channel error, but --ignore-negative-one is available (it previously was not). I don't know if this is what you mean by problem solved or not.

[anonymous12312421421]

In ubuntu 12.04 you can use the follow script and should fix the problem.

#!/bin/bash
ifconfig wlan0 down
iwconfig wlan0 mode managed
ifconfig wlan0 up
iwconfig wlan0 channel 11
# the "11" should be changed whenever you want to chose other channel. We must to change it everytime we want to use another channel.
ifconfig wlan0 down
iwconfig wlan0 mode monitor
ifconfig wlan0 up
# iwconfig wlan0 <-- this line is optional, you can erase the "#" if you want to, and it shows the monitor mode

You save it as you want e.g. "script-ng", then give it the exec with

# Chmod 700 ./script-ng

and you can use it as a root to change the channel.

I hope it helps.

Hi, I try the script previously posted but I alway get -1 running 'airodump-ng -c 6 -w psk mon0' and before 'airmon-ng start wlan0 6'. I correctly see the AP/clients on channel 6 but I can't get no wpa handshakes all client are not associated (but that is not true because I do that with my clients/AP). Any suggests? Regards.
