 Originally named Ethereal, the project was renamed Wireshark in May 2006 due to trademark issues.Wireshark is cross-platform, using the Qt widget toolkit in current releases to implement its user interface, and using pcap to capture packets; it runs on Linux, macOS, BSD, Solaris, some other Unix-like operating systems, and Microsoft Windows.There is also a terminal-based (non-GUI) version called TShark.
