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.

Wireshark Features:
1. Deep inspection of hundreds of protocols, with more being added all the time
2. Live capture and offline analysis
3. Standard three-pane packet browser
4. Multi-platform: Runs on Windows, Linux, OS X, Solaris, FreeBSD, NetBSD, and many others
5. Captured network data can be browsed via a GUI, or via the TTY-mode TShark utility
6. The most strong display filters in the industry
7. Rich VoIP analysis
8. Read/write many different capture file formats: tcpdump (libpcap), Catapult DCT2000, Cisco Secure IDS iplog, Microsoft Network Monitor, Network General Sniffer? (compressed and uncompressed), Sniffer? Pro, and NetXray?, Network Instruments Observer, Novell LANalyzer, RADCOM WAN/LAN Analyzer, Shomiti/Finisar Surveyor, Tektronix K12xx, Visual Networks Visual UpTime, WildPackets EtherPeek/TokenPeek/AiroPeek, and many others
9. Capture files compressed with gzip can be decompressed on the fly
10. Live data can be read from Ethernet, IEEE 802.11, PPP/HDLC, ATM, Bluetooth, USB, Token Ring, Frame Relay, FDDI, and others (depending on your platfrom)
11. Decryption support for many protocols, including IPsec, ISAKMP, Kerberos, SNMPv3, SSL/TLS, WEP, and WPA/WPA2
12. Coloring rules can be applied to the packet list for quick, intuitive analysis
13. Output can be exported to XML, PostScript?, CSV, or plain text.
