Ettercap is an open source network sniffer and logger/interceptor for Ethernet LANs. The software supports both passive and active dissection of many protocols, even ciphered ones, such as HTTPS and SSH.
In order to give users a complete and powerful sniffing suite, many sniffing modes were implemented in Ettercap. Plugins are also supported, and it features the ability to check whether you are in a switched LAN or not.
