The world's most popular network protocol analyzer.

Wireshark is the world's foremost network protocol analyzer. It lets you see what's happening on your network at a microscopic level. 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.

Plugin Development Changes On UN*X systems (excluding macOS when running from an app bundle, as with the official installer) extcap binaries are now searched for under the libexec directory by default, e.g., /usr/libexec/wireshark/extcap instead of /usr/lib64/wireshark/extcap or similar. This is the customary place for helper binaries, which as opposed to libraries do not need multiarch support. The location can be overridden via the environment variable WIRESHARK_EXTCAP_DIR. The extcap binaries shipped with Wireshark are installed in the new location, but third party extcaps may need packaging changes. This change was effective in version 4.6.0, but was not explicitly noted in the release notes previously. Note that some distributions do not use a libexec directory, such as Alpine Linux, which does not have multilib support. On such systems extcap binaries should be in the same location as before.
