How's your access point set up?Hey guys,
BackTrack 4 (prefinal)
with Alfa AWUS360H
I once cracked a WEP network with MAC filter, got the key and could obtain the IP without any problems. I leave it alone for a while (just interested in the challenge) and now I noticed it has changed. “WEP40” is now mentioned as Cipher (not WEP anymore) and there’s a new key. I cracked the key but I still can’t connect.
This is my procedure:
Ifconfig wlan1 hw ether 00:00:00:00:00:00 (known Mac)
airmon-ng start wlan1
airodump-ng -c 9 --bssid 00:00:00:00:00:00 -w save mon0
- no need of aireplay cuz packets came in fast
- enable wlan1, Advanced Options, WEP(Hex) (earlier I had to chose Shared/Restricted), entering the key. Connect
It’s validating without any problems but I can’t obtain an IP. It’s like the key would be wrong. So I collect packets another time but I still got the same key: 54:14:54:13:12:0A:BCE:F1:23:45:67:89 (first 5 pairs changed). I was confused about the ending (0abcde..) at first, but I think that’s because it’s 40 byte, so only the first 5 pairs matter. I tried to leave them out, still no IP. I got two validated MAC addresses, tried both, same result.
What does I have to do to get an IP?
