Getting Wireshark

Wireshark source code and installation packages are available from the download page on the main web site.

Vendor-supplied Packages

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.

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 About->Folders to find the default locations on your system.

Known Problems

Wireshark may appear offscreen on multi-monitor Windows systems. (Bug 553)

Wireshark might make your system disassociate from a wireless network on OS X. (Bug 1315)

Dumpcap might not quit if Wireshark or TShark crashes. (Bug 1419)

Wireshark might freeze when reading from a pipe. (Bug 2082)
