Wireshark is the world’s foremost network protocol analyzer. It lets you capture and interactively browse the traffic running on a computer network. It is the de facto (and often de jure) standard across many industries and educational institutions.

Feature:

• Deep inspection of hundreds of protocols, with more being added all the time
• Live capture and offline analysis
• Standard three-pane packet browser
• Multi-platform: Runs on Windows, Linux, OS X, Solaris, FreeBSD, NetBSD, and many others
• Captured network data can be browsed via a GUI, or via the TTY-mode TShark utility
• The most powerful display filters in the industry
• Rich VoIP analysis
• Read/write many different capture file formats: tcpdump (libpcap), Pcap NG, Catapult DCT2000, Cisco Secure IDS iplog, Microsoft Network Monitor, Network General Sniffer® (compressed and uncompressed), Sniffer® Pro, and NetXray®, Network Instruments Observer, NetScreen snoop, Novell LANalyzer, RADCOM WAN/LAN Analyzer, Shomiti/Finisar Surveyor, Tektronix K12xx, Visual Networks Visual UpTime, WildPackets EtherPeek/TokenPeek/AiroPeek, and many others
• Capture files compressed with gzip can be decompressed on the fly
• 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 platform)
• Decryption support for many protocols, including IPsec, ISAKMP, Kerberos, SNMPv3, SSL/TLS, WEP, and WPA/WPA2
• Coloring rules can be applied to the packet list for quick, intuitive analysis
• Output can be exported to XML, PostScript®, CSV, or plain text

Changelog:

# The following features are new:
* Wireshark can import text dumps, similar to text2pcap.
* You can now view Wireshark’s dissector tables (for example the TCP port to dissector mappings) from the main window.
* TShark can show a specific occurrence of a field when using ‘-T fields’.
* Custom columns can show a specific occurrence of a field.
* You can hide columns in the packet list.
* Wireshark can now export SMB objects.
* dftest and randpkt now have manual pages.
* TShark can now display iSCSI service response times.
* Dumpcap can now save files with a user-specified group id.
* Syntax checking is done for capture filters.
* You can display the compiled BPF code for capture filters in the Capture Options dialog.
* You can now navigate backwards and forwards through TCP and UDP sessions using Ctrl+, and Ctrl+. .
* Packet length is (finally) a default column.
* TCP window size is now avaiable both scaled and unscaled. A TCP window scaling graph is available in the GUI.
* 802.1q VLAN tags are now shown by the Ethernet II dissector.
* Various dissectors now display some UTF-16 strings as proper Unicode including the DCE/RPC and SMB dissectors.
* The RTP player now has an option to show the time of day in the graph in addition to the seconds since beginning of capture.
* The RTP player now shows why media interruptions occur.
* Graphs now save as PNG images by default.
