“Ethereal is a free network protocol analyzer for Unix and
Windows. It allows you to examine data from a live network or from
a capture file on disk. You can interactively browse the capture
data, viewing summary and detail information for each packet.
Ethereal has several powerful features, including a rich display
filter language and the ability to view the reconstructed stream of
a TCP session.”
“Ethereal 0.8.13 is now available. New dissectors include H.261,
TPKT, and IGRP. RTP and RTCP were re-written, and many other
dissectors were updated and improved. The wiretap library enables
Ethereal to read Nokia-firewall tcpdump files, Shomiti Surveyor 3.x
files, pppd log files (pppdump format), and NetXRay ATM files.”
