afair, the fms attack requires between 500,000 and 2,000,000 data packets and sometimes works. the aircrack should be more effective, but i havent had time to test aircrack yet.

Well, just my airport extreme base station seems to have no weak packets
when there are no clients.

I think that to crack one there must be a lot of traffic, not?
In one hour it generated only 5000 packets.

I havent tried it yet, but i have been developing my own
cross platform distributed wep cracker. Its been
cross-developed on ppc/osx and linux/x86 from the start so it
plays nice everywhere. Its just a bruteforcer so its good
when theres not a lot of data to crack. It was designed to
run on a cluster but it works just as well as any other
bruteforcer would on your own box. Screenshot at

code:

I havent released it yet so theres not much in the way of docs.
This isnt suited for those of you afraid of the command line -jc

It compiles nicely, thanks for bringing this to my
attention.. Has 
anyone tried this with kismac's pcap dumps yet?

Cracking via weak packets is broken on the current
version of Kismac. 
 If you save your Kismac dump files you can use a tool like
aircrack
(http://www.cr0.net:8040/code/network/)  to crack the
WEP key for a
specific BSSID. While the aircrack toolset was designed
for Linux,
the aircrack and 802ether applications compile and work
under MacOS 
X just fine.

In my tests I was able to crack a 128-bit WEP key after
capturing
about 500,000 encrypted packets. Notice I didn't say
weak packets 
as aircrack doesn't depend on "weak" packets, only packets with
unique IVs.

I've posted version 2.0 of Aircrack compiled for MacOSX at
http://www.macunix.net/Aircrack-2.0_MacOSX.zip

Please see the readme file on how to use aircrack.

That's a hard one. Anywhere from 10 to 10,000 depending on how
weak the weak packets are, and if the same weakness is
through out them. 
Even after a day or two monitoring my own network (which is
heavily
used) I still was unable to crack my wep. I had something like
15,000 weak packets.

Why everytime I try any crack method (bruteforce or
others), it 
says that there are not enough packets?

What is the minimum packets?
