Ethereal offers more protocol decoding and reassembly than any free sniffer out there and ranks well among the commercial tools. You've all used tools like tcpdump or windump to examine individual packets, but Ethereal makes it easier to make sense of a stream of ongoing network communications. Ethereal not only makes network troubleshooting work far easier, but also aids greatly in network forensics, the art of finding and examining an attack, by giving a better "big picture" view.
