hey
i wrote a small program you can use along side of your airodump-ng to search for specifics with auditory notification. like search for a specific MAC address, AP name, Encryption type, etc.. keeping the wardriving more organized. theres a video and all on the site too, so:
http://zombie.el.cx/catchme-ng/ test it out if you want its quite useful say if you know the MAC from a log in your router of a WiFu expert that was behind your "protected" network, or if you wanna play with routers that have the "default-ng" settings still active, it searches for that too. i got the idea from the movie "TrackDown' or "TakeDown" whatever its called now, when tsutomu was riding around in the van searching for the MIN of the cellphone Mitnick was using as a modem. .. so, catchme-ng a network-cracker!! - cheers - trevelyn.
