Packetyzer provides a Windows user interface for the Ethereal packet capture and dissection library. Ethereal is used by network professionals around the world for troubleshooting, analysis, software and protocol development, and education. Ethereal has all of the standard features expected in a protocol analyzer, and several features not otherwise available.
We’ve taken advantage of Ethereal’s open source license to add a Windows front end to extend its use. Packetyzer can capture from virtually any network adapter and supports many advanced features. Packetyzer is free and open source, and is licensed under the GPL.
Packetyzer supports all protocols which are supported by Ethereal, including IEEE 802.11 wireless LAN management frame, IEEE 802.11 wireless LAN, 802.1q Virtual LAN, 802.1x Authentication, and many more. For more information, view the complete list of supported protocols.
