Wireshark 0.99.6

Wireshark was know as Ethereal.

Wireshark is used by network professionals around the world for troubleshooting, analysis, software and protocol development, and education.

Wireshark has all of the standard features you would expect in a protocol analyzer, and several features not seen in any other product.

Its open source license allows talented experts in the networking community to add enhancements. It runs on all popular computing platforms, including Unix, Linux, and Windows.

Here are some key features of "Wireshark":

· Data can be captured "off the wire" from a live network connection, or read from a capture file.
· Ethereal can read capture files from tcpdump (libpcap), NAIs Sniffer™ (compressed and uncompressed), Sniffer™ Pro, NetXray™, Sun snoop and atmsnoop, Shomiti/Finisar Surveyor, AIXs iptrace, Microsofts Network Monitor, Novells LANalyzer, RADCOMs WAN/LAN Analyzer, HP-UX nettl, i4btrace from the ISDN4BSD project, Cisco Secure IDS iplog, the pppd log (pppdump-format), the AG Groups/WildPackets EtherPeek/TokenPeek/AiroPeek, or Visual Networks Visual UpTime. It can also read traces made from Lucent/Ascend WAN routers and Toshiba ISDN routers, as well as the text output from VMSs TCPIPtrace utility and the DBS Etherwatch utility for VMS. Any of these files can be compressed with gzip and Ethereal will decompress them on the fly.
· Live data can be read from Ethernet, FDDI, PPP, Token-Ring, IEEE 802.11, Classical IP over ATM, and loopback interfaces (at least on some platforms; not all of those types are supported on all platforms).
· Captured network data can be browsed via a GUI, or via the TTY-mode "tethereal" program.
· Capture files can be programmatically edited or converted via command-line switches to the "editcap" program.
· 683 protocols can currently be dissected:

· Output can be saved or printed as plain text or PostScript®.
· Data display can be refined using a display filter.
· Display filters can also be used to selectively highlight and color packet summary information.
· All or part of each captured network trace can be saved to disk.
