Does it work if you run following commands?

wget http://wireless.kernel.org/download/compat-wireless-2.6/compat-wireless-2010-10-16.tar.bz2
tar -jxf compat-wireless-2010-10-16.tar.bz2

I was searching for secured wireless network hacking via Google on Sunday, and I found your page Hacking WEP encryption on Ubuntu | My IT-blog to be extremely useful. Regards gill54@msn.com

Good tutorial, well written. A question though: I get the authentication and association message successful (fake auth) but my mac address is not listed along with the associated clients…this means if there is no clients associated in the AP, no wep crack! What am I doing wrong? I did the whole wep crack with clients already associated using their Mac address and it worked well, the thing is I cant get my Mac address associated with the AP, although it says the association is successful…Thanks a million

There are many possible root causes of this problem:

- The wireless card is set to a channel which is different from the AP. Solution: Use iwconfig and confirm the card is set to the same channel as the AP.

-The card is scanning channels. Solution: Start airodump-ng with the ”-c” or ”–channel” parameter and set it to the same channel as the AP.

-The ESSID is wrong. Solution: Enter the correct value. If if contains spaces or special characters then enclose it in quotes. For the complete details, see this FAQ entry.

-The BSSID is wrong. Solution: Enter the correct value.

-You are too far away from the AP and are not receiving any beacons. Solution: You can use tcpdump and/or airodump-ng to confirm you are in fact receiving beacons for the AP. If not, move closer.

-You are not receiving beacons for the AP: Solution: Use “tcpdump -n -vvv -e -s0 -i ” to confirm you are receiving beacons. Assuming you have dealt with with potential problems above, it could be the drivers or you have not put the card into monitor mode.

For all of the above, running airodump-ng and the related text file should provide all the information you require identify and correct the problem.

I really appreciate your tutorial. I am hacking to learn and not learning to hack. I need your help, please.
When I tried “aireplay-ng deauth” and “aireplay-ng fauth,” It gave me this error: “Waiting for Beacon Frame….” and then “No such BSSID available.” After that, it stopped.

To Faisal…
check your card capability on aircrack-ng.com

It works!
the only problem is that it took me 2 hours to hack my own wireless network.
Thanks for this tutorial!

Also I’ve done everything by the book, exactly BUT the last step

sudo aircrack-ng -0 -b 00:24:01:65:97:69 /home/wim/crackwepwifi-02.iv

gives me two results.

1) He says the file or directory does not exists
OR
2) He says the BSSID (or ESSID I forgot) is wrong.

I checked and checked and both are correct.

Do I actually have to create a file for instance on the desktop to record the outputdata from airodump?

I did :

sudo airodump-ng –channel 6 -w /home/redhat/desktop -i mon0

(I just placed that in the terminal, is that enough or should I actually create a file on the desktop for instance and then:

sudo airodump-ng –channel 6 -w /home/redhat/desktop/file -i mon0

)

I almost got it to work!!!!! I’m so close!

1) What do you do if the target host uses MAC filtering?
