Two output formats are supported: Prior to running you need to make sure the ZENA device is “unbound” from any kernel drivers. Main menu Skip to primary content. The Python script is available here. You will find a new file in that directory.

Make note of it. Zena Packet Capture Tool. One line per 64 byte chunk.

A level of 0 implies no debugging default9 maximum verbosity. It comes with free Windows-only software. 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.

ZENA device not found or not accessible”, that is likely your problem. The Python script is available here. Now connect the ZENA. There is no support for Linux and cannot be used with powerful tools like Wireshark.

You will find a new file in that directory. I guess we are all spoiled by Wireshark, but I was hoping for more detail and a better UI.

A number between 11 and 26 is expected. See comments near the top of the C file on how to compile and run. 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 uxb data endpoint for delivering frames.

Plugging into a Linux box, it was clear that the device was using the USB HID, which was good news for me since it would be simpler to reverse the configuration details. Ubs would love to be able to check for this and unbind programatically, but I don’t know how to go about it. Using the SnoopyPro USB snifferI was able to look at the USB packets, observing data from frames shown by the sniffer, as well as recording the configuration activity based on the channel I microcjip to capture microchipp.

Each chunk is prefixed with a timestamp obtained from the host computer -v will display version information and quit. Two output formats are supported: Awesome work and thanks for making your tool available as open-source. This will be incorporated in the next release — version 0.

You’ll probably need to be logged in as root to do all of these things. Main menu Skip to primary content.

The Zena sniffer can save a capture in a proprietary file formatand can export selected frames to the clipboard in space-delimited hex bytes. Ysb Post Older Post Home. Posted by Joe Desbonnet at Linux Microchip Zena data, isn’t it beautiful? 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.


There is very little documentation available for the device hardware.

You can specify a BMP background as a floorplan and move the nodes to their physical locations as well. It is possible to check if a device is bound to a kernel driver and unbind it in libusb 1.

On Ubuntu you can do sudo bash to avoid prefixing everything with “sudo”. I have updated this tool sena manage the new hardware version based on the Zeja chip.
