The Ethereal network protocol analyzer has changed its name to Wireshark 64-bit. The name might be new, but the software is the same. Wireshark's powerful features make it the tool of choice for network troubleshooting, protocol development, and education worldwide.

An open-source network protocol analyzer that lets you capture and interactively browse the traffic running on a computer network.

Originally named Ethereal, it was rebranded as Wireshark in 2006 and has since become a go-to tool for network troubleshooting, analysis, software and communication protocol development, and education. It's available for Windows, macOS, Linux, and other Unix-like operating systems.

The app was written by networking experts around the world and is an example of the power of open-source. Wireshark 64-bit is used by network professionals around the world for analysis, troubleshooting, software and protocol development, and education.

The program has all of the standard features you would expect in a protocol analyzer, and several features not seen in any other product. Its open source license allows talented experts in the networking community to add enhancements.

Highlights

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.
