Wireshark
From SecurityTools
Description
Wireshark is a free and open-source network protocol analyzer that works on all major operating systems. Wireshark was originally named Ethereal, but changed its name in 2006 due to trademark issues. The tool can be downloaded from the official site, and copious documentation and tutorials are also available there.
For full functionality, Wireshark needs to be run in promiscuous mode. This requires root or administrator privileges, depending on the operating system. It can be run with normal user privileges, but this limits the tool to only sniffing packets to and from the host machine.
