Posted by Joe Desbonnet at One line per 64 byte chunk.

This will be incorporated in the next release — version 0. The Python script is available here.

The packet capture output is sent to standard output. A number between 11 and 26 is expected.

Using PyUSB with the excellent Pymissle project by Scott Weston as an example, I quickly put together a tool that can set the channel number and capture frames from the Zena device, dumping the hex bytes to stdout. In this post I’ve documented reverse engineering efforts by myself and others and present a small C utility for pcap packet capture on the Linux platform.

I have micrrochip this tool to manage the new hardware version based on the MRF24J40 chip. With this information, it was straightforward to identify the USB endpoint 0x01 as the control channel for setting the channel and USB endpoint 0x81 as the data endpoint for delivering frames.

Linux Microchip Zena data, isn’t it beautiful? I guess we are all spoiled by Wireshark, but I was hoping for more detail and a better UI. See comments near the top of the C file on how to compile and run.

A level of 0 implies no debugging default9 maximum verbosity. It is possible to check if a device is bound to a kernel driver and unbind it in libusb 1.

The Zena sniffer can save a capture in a proprietary file formatand can export selected frames to the clipboard in space-delimited hex bytes. ZENA device not found or not accessible”, that is likely mcirochip problem. Make note of it. With no Linux support, I decided to write my own user space Linux driver to capture packets with the goal of integrating it into libpcap captures and other tools including Kismet Newcore.

Two output formats are supported: Zena Packet Capture Tool. Zena Sniffer Network Configuration Display. This is how to “unbind” it: Plugging into a Linux box, it was clear that the device jicrochip using the USB HID, which was good news for me since it would be simpler to reverse the configuration details. It comes with free Windows-only software.

Each chunk is prefixed with a timestamp obtained from the host computer -v will display version information and quit.

Update 20 Feb Now connect the ZENA. Zenna would love to be able to check for this and unbind programatically, but I don’t know how to go about it. Prior to running you need to make sure the ZENA device is “unbound” from any kernel drivers. Awesome work and thanks for making your tool available as open-source.
