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. Now includes a brand new NetWare Core Protocol dissector. Several bugs were fixed and support for new protocols was added, including AFP, AODV, ASAP, ASP, ATP, DCCP, LMP, M2UA, and WebDAV (HTTP).
