 or drop a packet) on the fly is also possible, keeping the connection
 synchronized.

 Many sniffing modes are implemented, for a powerful and complete
 sniffing suite. It is possible to sniff in four modes: IP Based, MAC Based,
 ARP Based (full-duplex) and PublicARP Based (half-duplex).
 .
 Ettercap also has the ability to detect a switched LAN, and to use OS
 fingerprints (active or passive) to find the geometry of the LAN.

 This package contains the Common support files, configuration files,
 plugins, and documentation. You must also install either
 ettercap-graphical or ettercap-text-only for the actual GUI-enabled
 or text-only ettercap executable, respectively.
