WireShark overview
Wireshark is one of the world's foremost network protocol analyzers, and is the standard in many parts of the industry. It is the continuation of a project that started in 1998. Hundreds of developers around the world have contributed to it, and it it still under active development.
Wireshark has a rich feature set which includes the following:
- Standard three-pane packet browser
- Multi-platform: Runs on Windows, Linux, OS X, Solaris, FreeBSD, NetBSD, and many others
- Multi-interface: Along with a standard GUI, Wireshark includes TShark, a text-mode analyzer which is useful for remote capture, analysis, and scripting
- The most powerful display filters in the industry
- VoIP analysis
- Live capture and offline analysis are supported
- Read/write many different capture file formats: tcpdump (libpcap), NAI's Sniffer (compressed and uncompressed), Sniffer Pro, NetXray, Sun snoop and atmsnoop, Shomiti/Finisar Surveyor, AIX's iptrace, Microsoft's Network Monitor, Novell's LANalyzer, RADCOM's WAN/LAN Analyzer, HP-UX nettl, i4btrace from the ISDN4BSD project, Cisco Secure IDS iplog, the pppd log (pppdump-format), the AG Group's/WildPacket's EtherPeek/TokenPeek/AiroPeek, Visual Networks' Visual UpTime and many others
- Capture files compressed with gzip can be decompressed on the fly
- Hundreds of protocols are supported, with more being added all the time
- Coloring rules can be applied to the packet list, which eases analysis

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.
