buttsniffer

Hi folk! Anybody knows how to use Buttsniffer? I can listen to ethernet frames in our network, but after a few minutes I`ve got a huge File with over 50MB... I read that there is an option to listen only to POP3 password and so funny things... At the moment I listen the network with the options : buttsniff -d 0002 pws.txt e Please mail me directly!!! ThanX (and Sorry for my fucKKK English!!!) -@HiNSe@-
