Ethereal allows talented is used by network professionals around the world for troubleshooting, analysis, software and protocol development, and education. It 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 licenseexperts in the networking community to add enhancements. It runs on all popular computing platforms, including Unix, Linux, and Windows.

Features:

  • 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), NAI’s Sniffer (compressed and uncompressed), Sniffer Pro, NetXray, Sun snoop and atmsnoop, Shomiti/Finisar Surveyor, AIX’s iptrace, Microsoft’s Network Monitor, Novell’s LANalyzer, RADCOM’s WAN/LAN Analyzer, HP-UX nettl, i4btrace from the ISDN4BSD project, Cisco Secure IDS iplog, the pppd log (pppdump-format), the AG Group’s/WildPacket’s 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 VMS’s 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
  • 759 protocols can currently be dissected
