Ettercap 0.6.b is a network sniffer/interceptor/logger for switched LANs. It uses ARP poisoning and the man-in-the-middle technique to sniff all the connections between two hosts. Features character injection in an established connection - you can inject characters to server (emulating commands) or to client (emulating replies) while maintaining an established TCP connection! Integrated into a easy-to-use and powerful ncurses interface.
