However, we obviously dont want to observe the package via commandline interface when we have a powerful wireshark, the problem is that the OpenWRT board is not capable of installing Wireshark. Just ssh to the router and run the command tcmpdum. I installed the OpenWRT on that, from there, it is the fullfearuted router, I configured it to work like a switch and install tcpdump so it can capture the network packages flowing through it, and because our eval board is connected to it, so done, we have the capability to capture the message from the board. and fortunately, I have a spare EspressoBin, an SBC board with powerful networking capability, hmm it seems that it’s the time it shining. Look at the diagram, you will see that I have a main server works as the debug station as I mentioned. I would describe a bit about my my home network setup in the following diagram. I have some valuable tools that the normal person would have overlooked it. You know, that task is trivial if you can connect the the target hardware to the LAN port on your PC. The problem rose when we work with the Ethernet feature of the HW target, we would like to analyze what if our board sending out something. It is the trivial task for the very good debugger we had, it does support the remote debugging, the hardware target and the debugger is placed at my home, is connected to the internet, the other person will run the client debugger on their PC, connected to the debugger in my home and debugging like they have the connected the debugger with their PC. The solution here is that I will setup the debug station in my house so that the 2 other folks can access to it. At that time we are doing the project that working with the ethernet feature, our project have 3 member shared one physically hardware. Honestly, I prefer working in office because of the professionalism feels and the we have all the supporting tools in the office (fancy tools, big screen, and obviously beautiful ladies as well jk). The background storyĭuring the pandemic in my country in 2021 summer, we are recommended to work from home. ![]() ![]() This post is just way I spent my free time to record what I have done during the hard time in the pandemic. Using wireshark and sshdump to capture ethernet packets remotely
