Wireshark is a free and open-source packet analyzer


Wireshark is a free and open-source packet analyzer.
It is used for network troubleshooting, analysis, software
and communications protocol development, and education.
Originally named Ethereal, in May 2006 the project was
renamed Wireshark due to trademark issues.





Wireshark is cross-platform, using the GTK+ widget toolkit to implement its user interface, and using pcap to capture packets; it runs on various Unix-like operating systems including Linux, Mac OS X, BSD, and Solaris, and on Microsoft Windows. There is also a terminal-based (non-GUI) version called TShark. Wireshark, and the other programs distributed with it such as TShark, are free software, released under the terms of the GNU General Public License.

There is also a malicious rogue anti-spyware program called Wireshark Antivirus that reports false information. This is in no way related to the packet analyzer program, Wireshark, and the two should not be confused.
