I really have just 50,- USD for this project as budget!:
I have a FritzBox 7050 from AVM ([url removed, login to view]) which runs some kind of linux. I want to compile the DSNIFF package with all parts like webspy, etc...
I also am looking for a VoIP based sniffer which just records all VoIP SIP traffic into WAV files on the harddrive and is so easy to handle like the dsniff package.
