Free fddi software for windows

Wireshark 1.1.1 provides users with a powerful yet totally free network protocol analyzer for Windows and Unix
The Ethereal network protocol analyzer has changed its name to Wireshark.The name might be new, but the software is the same. Wiresharks powerful features make it the tool of choice for network troubleshooting, protocol development, and education worldwide.
Wireshark was written by networking experts around the world, and is an example of the power of open source
Wireshark is used by network professionals around the world for analysis, troubleshooting, software and protocol development and education.
The program 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.
Major Features:

1. Data can be captured "off the wire" from a live network connection, or read from a capture file.
2. Wireshark 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.
3. 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).
4. Captured network data can be browsed via a GUI, or via the TTY-mode "tethereal" program.
5. Capture files can be programmatically edited or converted via command-line switches to the "editcap" program.
6. 602 protocols can currently be dissected
7. Output can be saved or printed as plain text or PostScript.
8. Data display can be refined using a display filter.
9. Display filters can also be used to selectively highlight and color packet summary information.
10. All or part of each captured network trace can be saved to disk.

1. The following vulnerabilities have been fixed:
   • The NCP dissector was susceptible to a number of problems, including buffer overflows and an infinite loop. Versions affected: 0.9.7 to 1.0.2
   • Wireshark could crash while uncompressing zlib-compressed packet data. Versions affected: 0.10.14 to 1.0.2
   • Wireshark could crash while reading a Tektronix .rf5 file. Versions affected: 0.99.6 to 1.0.2
2. The following bugs have been fixed:
   • 802.11 WPA/WPA2-PSK Unable to decode Group Keys. (Bug 1420)
   • Packets could wrongly be dissected as "Redback Lawful Intercept" (Bug 2376)
   • MIKEY dissector improvements (Bug 2400)
   • tvb_get_bits{16|32} could read past the end of a tvbuff (Bug 2439)
   • Incorrect wslua function names. (Bug 2448)
   • Memory corruption in wslua. (Bug 2453)
   • Unknown PPPoE TAGs which are present in a PPPoE discovery packet are not displayed under "PPPoE Tags" subtree/section. (Bug 2458)
   • Following a TCP stream could incorrectly reassemble packets. (Bug 2606)
   • SIP decode shows fully expanded "Content-Length" header instead of compact form. (Bug 2635)
   • Segmentation fault loading trace containing NCP packets. (Bug 2675)
   • SIP packets might incorrectly be displayed as malformed. (Bug 2729)
   • RTCP BYE padding interpreted incorrectly. (Bug 2778)
   • Reversed RTP stream is saved as silent .au file, forward stream saves correctly. (Bug 2780)
   • Fix some lint warnings. (Bug 2822)
   • Setting a duration on a capture file would capture for an extra second.
