![]() IF the packets, at some layer, are carrying a text-based protocol, such as the FTP control protocol, SMTP, or HTTP requests/responses and their headers, then SOME of the data in the file will be text, but it will NOT all be text. w writes out a completely binary file, in pcap format, which is intended to be read by tcpdump or by other programs such as Wireshark, NOT to be directly read by humans! txt, you're misunderstanding what -w does. Lastly, follow the steps of the CC2531 instructions above to set up your encryption keys the same.If you use -w with a name that ends with. Then, apply a filter udp.port = 17754 in order to filter down to only Zigbee traffic. Once you have the application running, you should see it connect to and start sniffing traffic on the network.Īfter that, open up Wireshark and start capturing on the loopback adapter. On linux, PORT will be something like /dev/ttyUSB3 or wherever you plugged in your HUSBZB-1 device. On Windows, PORT should be replaced by COM5 or whatever you wrote down in step 1. ![]() In a terminal or command line, run java -jar ZigbeeSniffer.jar -baud 57600 -flow hardware -port. It shouldn't matter whether or not you use Winpcap compatibility mode. No extra software besides ZigbeeSniffer.jar and Wireshark is needed # Windowsĭownload and install and make sure you select to install the "Npcap Loopback Adapter" when installing. Scroll down to the bottom of the README of to find how a precompiled jar file can be downloaded. You can find this by going to "Ports (COM & LPT)" in the device managerīoth Windows and Ubuntu use the same program for sniffing.Write down the com port of the ZigBee device, something like COM5 or COM6.Windows will prompt that it cannot confirm the device ID, click "Yes" to proceed.Select "Silicon Labs CP210x USB to UART Bridge" and click "Next".Enter the folder name where you extracted the downloaded drivers: C:\CP210x_Windows_Drivers.Leave "Show All Devices" selected and click "Next".Select "Let me pick from a list of available drivers on my computer".Select "Browse my computer for driver software".Right-click on "Other Devices > HubZ ZigBee Com Port" (NOT Z-Wave) and select "Update driver".Extract drivers to a folder (I'll use C:\CP210x_Windows_Drivers as an example).Download Silicon Labs CP210x drivers open in new window.On linux systems, the HUSBZB-1 or EZSP stick should work out of the box with no modifications. Windows machine (tested with Windows 10).If you happen to have a spare HUSBZB-1 or EZSP stick, you can also use this to sniff traffic. You may need to remove modemmanager as this has been known to cause issues.If you get couldn't run /usr/bin/dumpcap in child process: permission denied when running whsniff, check if /usr/bin/dumpcap is executable for everyone.turning on a light you will see a message similar to: Now Wireshark is able to decrypt the messages. Open the message and expand ZigBee Network Layer Data -> ZigBee Security Header.Ĭopy the key value, as shown above and go to Edit -> Preferences -> Protocols -> ZigBee -> Edit and add the key with Byte Order Normal. Pair a new device to the network (or re-pair an existing one) and grab the message where the Info is Device Announcement. ![]() ![]() If you don't want to translate the numbers, the network encryption key is also exposed when a device joins the network. PS: Of course it gets not sent anywhere, just a local in-browser converter. You can paste your network_key below to convert it. If you changed your network_key, then convert each number into its 2-digit hexadecimal value, and combine them all with : between. There are two ways to do this:īy default, if you haven't changed network_key in your configuration.yaml this will be 01:03:05:07:09:0B:0D:0F:00:02:04:06:08:0A:0C:0D. Next we need to figure out the network encryption key (Transport Key). NOTE: The Hue bridge uses a different Trust Center link key open in new window Set Security Level to AES-128 Encryption, 32-bit Integrity Protection and click on Edit. The second one is the network encryption key (Transport Key).Īdd the Trust Center link key by going to to Edit -> Preferences -> Protocols -> ZigBee. The first one is the Trust Center link key, which is the same for (almost) every Zigbee network. As these messages are encrypted we need to add 2 encryption keys. Wireshark will start and log the Zigbee messages. For ZBOSS make sure the correct Zigbee channel is set, by default it will sniff on channel 0x0C (12) but the default Zigbee2MQTT channel is 11 ( 0x0B (11)). For Windows run the ZBOSS executable in gui\zboss_sniffer.exe, enter the path to your Wireshark executable and click on the Start button. ![]()
