Wireshark 1.02 is a Protocol Analyzer product from wireshark.org, get 5 Stars SoftSea Rating, Wireshark (also known as Ethereal) is a network protocol analyzer that enables you to capture and examine data from a live network or from a capture file on disk. You can interactively browse the capture data and view summary and detail information for each packet. Wireshark has several strong features, including a rich display filter language and the capability to view the reconstructed stream of a TCP session.
Wireshark can read capture files from tcpdump (libpcap), NAI Sniffer (compressed and uncompressed), Sniffer Pro, NetXray, snoop, Shomiti Surveyor, AIX's iptrace, Microsoft Network Monitor, Novell's LANalyzer, RADCOM's WAN/LAN Analyzer, HP-UX nettl, ISDN4BSD, Cisco Secure IDS iplog, the pppd log (pppdump-format), and the AG Group s/Wildpacket Etherpeek.
Wireshark can also read traces made from Lucent/Ascend WAN routers and Toshiba ISDN routers. Any of these files can be compressed with gzip and Wireshark will decompress them on the fly.
