I'll take this one to the wireless list once I've subscribed but just
to let people know that I tried again to crack my key and failed. I
collected 1million IVs with a mix of aireplay and copying large files
between devices. Even with that I still hadn't cracked it after 521
minutes so I gave up.
I'm going to have a read of all the articles that people sent me and
if I have any more prolems I'll put them on the wireless list.
Thanks All
Robin
PS the machine doing the cracking is a Sempron 3000+ with a gig of ram
in case anyone was going to suggest the machine may not be up to it!

In fact, as it is a statiscical attack, it does not depend on the "weaks IV"
but on the quantity.
It's like the more unique IVs, the higher the probability to find the wep
key quicker. Anyway, it's probability, even a 99% probability does not
ensure you'll win!!
In practice I used to crack 104 bit wep keys with around 500 000 packets. If
you're not lucky you will need more, till a million packets.
While collecting packets you can run aircrack. For example you have
collected 500 k packets, you can run aircrack on the capture file as it
still grows (capturing with airodump), it is even faster. That's what I
usually do.

Subject: Cracking WEP and WPA keys
I cracked my own WEP a few months ago, I just needed to collect about
800,000
IVs with airodump, then ran aircrack and I got the key in less than one
second.
(104 bit WEP) By the way, i collected the whole traffic in 2 hours.
It doesn't just depend on the number of collected IVs, but the weak IVs
and your
hardware. My frist try was using a 3Com Card, but I wasn't collecting
enough
IVs, then I tried with a Prism2 Intersil card and it was done.
You should give it more time to the airodump stage than to the aircrack
one.
Greetings,
Eduardo.
