Hey I am capturing IEEE 802.11 packets on RedHat 7.2 kernel v 2.4.18 using
Ethereal 0.9.3 + Libpcap 0.7.1 in "Monitor Mode". I am using Cisco Aironet
350 PCI adapter. I am saving and subsequently feeding these capture files to
AirSnort 0.2.1 and WEPCrack. But so far unable to crack the WEP keys. I
think I am mistaking somewhere, but don't know where :-( . I am not very
sure about how to use WEPCrack and AirSnort 0.2.1, but just trying to
emulate the READMEs. I case of AirSnort getting this warning after I start
it-
Warning: arptype 801 not supported by libpcap - falling back to coocked
socket.
Any help on this would be highly appreciated.
Regards,
Narayan Sharma
