Ethereal is a GTK+-based network protocol analyzer, or sniffer, that lets you capture and interactively browse the contents of network frames. The goal of the project is to create a commercial-quality analyzer for Unix and to give Ethereal features that are missing from closed-source sniffers. Screenshot available here for details. The TAP subsystem received major updates. Ethereal can display more statistics, and several graphs have been added to Ethereal. New protocols were added and updated.
