I guess BackTrack 4 would at least provide you with a more up to date and
capable Wireshark, although I've a hard time finding the package list for it.

Indeed. :D I just updated to the latest version (painless but it took an age to compile :P).

No extra luck though sadly :(

IIRC WPA decryption is not available on Linux - it requires the use of
airpcap on Windows and if on windows, it will only work with PSK, not
802.1X of course.

I was under the impression using airpcap was an optional extra on WIndows - but that Wireshark could decrypt packets (the userguide suggests this). I will have a re-read.

 it will only work with PSK, not 802.1X of course.

Im not sure I understand that. Surely if the PSK is known traffic can be decrypted and the 802.11 traffic can then be decoded into HTTP etc.?

. Aircrack-ng includes a tool called Airdecap-ng which you can use to decrypt the traffic.

Ah man :( I feared this is where I would have to go. Thanks for the tip - I'll give it a go and let you know what happens.

Thanks for all the hints/tips. If anyone else has more to add please do :D

Tom

Hi,

Thanks,
