An open-source and free packet analyzer is called Wireshark. It creates software and communications protocols, network troubleshooting, analysis, and teaching. Due to trademark concerns, the project was renamed Wireshark in May 2006 from its original moniker, Ethereal. Cross-platform Wireshark works on Linux, macOS, BSD, Solaris, Unix-like operating systems, and Microsoft Windows. It uses the Qt widget toolkit in recent versions to implement its user interface and pcap to collect packets. A different (non-GUI) version named TShark is terminal-based. Following the provisions of the GNU General Public License version 2 or any later version, Wireshark and its additional applications, such as TShark, are free software.
