From Wireshark development team
Wireshark is the world's foremost network protocol analyzer, and is the de facto (and often de jure) standard across many industries and educational institutions.
Wireshark development thrives thanks to the contributions of networking experts across the globe. It is the continuation of a project that started in 1998.
Wireshark has a rich feature set which includes the following:
* 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), 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,
The following bugs have been fixed:
Wireshark is unresponsive when capturing from named pipes on Windows. (Bug 1759)
Ring buffers are no longer turned on by default when using multiple capture files.
New and Updated Features
The following features are new (or have been significantly updated) since version 1.4:
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.
TShark can read and write host name information from and to pcapng-formatted files. Wireshark can read it. TShark can dump host name information via
The tshark -z option now uses the
syntax instead of
for all protocols that support service response time statistics. This syntax now matches Wireshark's syntax for this option.

Wireshark source code and installation packages are available from http://www.wireshark.org/download.html.
Most Linux and Unix vendors supply their own Wireshark packages. You can usually install or upgrade Wireshark using the package management system specific to that platform. A list of third-party packages can be found on the download page on the Wireshark web site.
Wireshark and TShark look in several different locations for preference files, plugins, SNMP MIBS, and RADIUS dictionaries. These locations vary from platform to platform. You can use About→Folders to find the default locations on your system.
