Wireshark is a free and open-source packet analyzer. It is used for networktroubleshooting, 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-likeoperating systems
- Data can be captured "from the wire" from a live network connection or read from a file thatrecorded already-captured packets.
- Live data can be read from a number of types of network, including Ethernet, IEEE 802.11, PPP, and loopback.
- Captured network data can be browsed via a GUI, or via the terminal (command line) version of the utility, TShark.
- Captured files can be programmatically edited or converted via command-line switches to the "editcap" program.
- Data display can be refined using a display filter.
- Plug-ins can be created for dissecting new protocols.
- VoIP calls in the captured traffic can be detected. If encoded in a compatible encoding, the media flow can even be played.
- Raw USB traffic can be captured.
