Allow the user to be able to use tcmpdump over an SSH connection (remote connection) Sudo add-apt-repository ppa:wireshark-dev/stable #Xquartz wireshark installFrançois has great instructions on his blog – here are the most relevant bits for us at this moment: // Install Wireshark (development version) Now you want to make sure Wireshark is installed. XAuthLocation /usr/X11/bin/xauth Step 3: Install Wireshark So in your config file, located at ~/.ssh/config you should add a couple of lines: ForwardX11 yes However, before you SSH in you should make sure your SSH config includes X-Forwarding. (I keep seeing L4T BRO!, and the developers just laugh at me.) And with it you can connect to your Nano via SSH by to 192.168.55.1. On the WLAN Pi it’s USBO:, but here it’s lt4br0. TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 In fact, if you look at the output of “ifconfig -a” on the Nano with the USB connected you should see: l4tbr0: flags=41 If you ever see “L4T” references, that is what it means. By the way, “Linux for Tegra” is the official name of the OS running on the Nano. Yep, it works as an RNDIS device, very similar to what you see with the WLAN Pi if you have one of those (and you should). If you plug it in to your Mac you should see something like this: But did you know that the mini port still works while the DC jack power is used? It doesn’t work as a host port but it works just great as a device port. Step 2 – Connect to the NanoĪs I mentioned in my original post, I power the Nano via the DC barrel connector because it allows 10 watt operation, which is a nice chunk of power. Yay!īy the way – if Linux is your desktop of choice then you already have an X11 server, but you also probably already knew that. #Xquartz wireshark downloadSo go to the XQuartz site, download XQuartz, and that gives you an X11 server. That has fallen by the wayside but it can still be yours thanks to the XQuartz project. So no matter which Linux GUI you use it can trace its roots back to X11 and believe it or not when MacOS X first came out it had native X11 support. I’ll be sorting out those details shortly. This method is Mac/Linux oriented but I’m confident it should be easy to do with the Windows Subsystem for Linux. Let me show you what I’ve been doing to make my captures a bit easier. A lot of really cool folks like François Vergès and Gjermund Raaen have been using the Nano as an 802.11ax capture tool, as have I.
