Stuck on the last step: aircrack command wont decrypt WEP key

[tmontana]

morning all. well i have been up all night trying to figure this out. Basically im trying to crack the WEP on my own network. i followed xploitz video tutorial (thanks for that) and everything went perfect but after entering the final command:

aircrack-ng -n 64 --bssid 11:22:33:44:55:66 eircom4070-01.cap

and 2 hours later aircrack still hasn't cracked the 64 WEP key, so i dug around on the forums and google and then entered:

aircrack-ng -f 4 -m 11:22:33:44:55:66 -n 64 eircom4070-01.cap

another 2 hours later and it still hasnt cracked the key.when i gave up after both of these attempts i had collected more than 700.000 IV's. should i have waited longer? packets were read and sent successfully and i had over 60,000 ARP requests.

im not lazy and have honestly searched to find a solution for this problem but now im posting this because im stuck

i would like to know if anyone has any suggestions as to how i can get aircrack to decrypt the key

all opinions/comments welcome

thank you in advance

What version of aircrack are you using, and is this under bt2 or bt3 ?

No harm no foul, the more opinions the better as far as I'm concerned

thanks for the reply, im using BT3 and the version of aircrack is Aircrack-ng 1.0 beta1 r857

any suggestions on why the key isn't decrypting ?

thanks

thanks

In that case it uses the ptw method by default, so a 64 bit key should only need around 30-50k ivs. There are always times when it just doesn't work for no obvious reason.

When you open the file with aircrack, how many ivs does it tell you you have ?

on both attempts i had over 700,00 IV's

im just wondering if it could be my wireless card, its a Cnet cwd-854 with RT73 chipset, i checked the compatibilty thread and its in the "unknown" section.

anything else i could try?

Thanks balding_parrot, I agree

RT73 is supposed to work perfect in BT3, so I don't think it's a compatibility issue.

I've highlighted what you could change, Im sure you have more than ONE.cap file? is it reading all the information from just that 1.cap file? shouldnt it be reading / cracking info from all your .cap files?

can you try this

aircrack-ng *.cap
or
aircrack-ng -n 64 --bssid 11:22:33:44:55:66 *.cap

MORE IMPORTANTLY.....

when you done airodump-ng, what / where did you write your files to?
I think it might be best if you copy & paste your commands here from start to finsh so we can see whats happening

as if you watch either -=Xploitz=- or My videos or anyone elses you'll see something like
airodump-ng -c 11 -w WEP --bssid 12345abcde ath0 <<<< THIS IS WRITING TO WEP & that's what we crack>>>>>

[tmontana]

thank you for all the replies, its much appreciated

@samsung: i have just checked my root folder and there is only 1 file there and its 82MB and the file is called "eircom4070-01.cap" . here is a list of the commands i used from start to finish, everything went perfect or so i thought but the WEP key just wont crack

1..airodump-ng rausb0 (to view traffic)
airodump-ng -c 6 -w eircom4070 --bssid 00:0F:CC:83:82:XX rausb0

2..aireplay-ng -1 0 -a 00:0F:CC:83:82:XX -h 00:08:a1:a1:21:XX rausb0

3..aireplay-ng -3 -b 00:0F:CC:83:82:XX -h 00:08:a1:a1:21:XX rausb0

4..aircrack-ng -n 64 --bssid 00:0F:CC:83:82:XX eircom4070-01.cap

i left this for 2 hours and nothing, so i tried step 4 again with this command:

aircrack-ng -f 4 -m 11:22:33:44:55:66 -n 64 eircom4070-01.cap


this is where im stuck now, its collecting plenty if IV's(nearly 1 million) but WEP key wont crack

any thoughts?

thanks once again
