How to connect an embedded linux system to pc via ethernet?

ru flag
Serena Graziano

I have a custom board with a linux system and I want to connect it via ssh to my personal pc running ubuntu over ethernet.

With window I use putty to connect to the board, but in linux I don't know even how to start. How can I see if the board is even connected to the pc ? I need some drivers since I'm using an usb-to-ethernet cable? And In general how should I proceed to connect my board and access to it with ssh ?

Thank you and sorry if the question is to general .

Also I think that the usb-ethernet adapter is not recognized as a eth connection, this is the output of:

First of all, you actually have two questions, first is about the ssh connection and the second is about USB-Ethernet, please create two separate questions next time and search first, both of them were already answered. SSH connection question was answered many times I think, here is the one of such questions: https://stackoverflow.com/questions/31761558/connect-two-local-linux-computers-via-ssh And here is the one for your USB-Ethernet device: https://askubuntu.com/questions/1215551/ubuntu-server-19-10-ax88179-driver-problem

To find which computers are connected to your network you have to log in to your router. It shows a list of all connected devices and the IP for each of those connections. Most routers allow you to log in via a web browser.

Then you can install Remmina (or something similar) on your personal pc to connect to another computer on your network, for example the customer board you mention in your question.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
