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.

Wireshark development thrives thanks to the contributions of networking experts across the globe. It is the continuation of a project that started in 1998.

Changelog v1.9.0
New and Updated Features

The following features are new (or have been significantly updated) since version 1.8:

  • Wireshark on 32- and 64-bit Windows supports automatic updates.
  • The main welcome screen and status bar now display file sizes using strict SI prefixes instead of old-style binary prefixes.
  • It is now possible to compare two fields in a display filter (for example: udp.srcport != udp.dstport). The two fields must be of the same type for this to work.
NOTE 0: Many more not listed here.
NOTE 1: This is an experimental release intended to test features that will go into Wireshark 1.10.
