    A multipurpose sniffer/interceptor/logger for switched LAN.

    It supports active and passive dissection of many protocols (even ciphered ones) and includes many feature for network and host analysis.

    Ettercap is a suite for man in the middle attacks on LAN. It features sniffing of live connections, content filtering on the fly and many other interesting tricks.
