What is Wireshark?

Wireshark is the world’s most popular network protocol analyzer. It is used for troubleshooting, analysis, development and education.

What’s New

We do not ship official 32-bit Windows packages for Wireshark 4.0 and later. If you need to use Wireshark on that platform, we recommend using the latest 3.6 release. Issue 17779

If you’re running Wireshark on macOS and upgraded to macOS 13 from an earlier version, you will likely have to open and run the “Uninstall ChmodBPF” package, then open and run “Install ChmodBPF” in order to reset the ChmodBPF Launch Daemon. Issue 18734.

File Locations

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 Help  About Wireshark  Folders or tshark -G folders to find the default locations on your system.
