To install the tcpdump utility on Fedora, CentOS, and RHEL, issue the following command: sudo dnf install tcpdump On Arch-based systems, run: sudo pacman -S tcpdump On Debian/Ubuntu derivatives, run: sudo apt- get install tcpdump To install tcpdump, fire up the terminal and run the command corresponding to the Linux distro that you're currently using: In case you are unable to run the tcpdump command and are stuck at the " tcpdump: command not found" error, let's learn how to install tcpdump on your Linux machine. So you should be able to use it right away by typing in tcpdump with a sudo prefix. On Wireshark I don't see this traffic.Tcpdump usually comes pre-installed with all mainstream Linux distributions and security-based alternatives. I know this solution does not work as when I listen on the usb0 interface on the gateway with tcpdump, I see a bunch of packets (note left-side of terminal).
Note that I have an ssh-key set up for my remote forward as shown in the left-side of the terminal. The only solution I've been able to come up with to attempt to achieve this is do the following shown in the Wireshark remote capture via remote forward image. The ionoPi contains and runs all the tests for the gateway we are developing and I'd like to see ethernet traffic on the usb0 interface on the gateway to troubleshoot some of these tests. no gui on the pi and gateway) that sits between my ubuntu vm (subnet 254) and the gateway (subnet 90). I have a ionoPi that is connected to the gateway (i.e. I'm trying to capture packets on a usb over ethernet interface (usb0) on a gateway.
