Question about "How to connect remotely to another Ubuntu computer".
It was required to give remote access to the local machine. At first I thought that everything here was similar to connecting to the server, that is, I simply entered ssh [email protected]_IP
Answer:

Unable to negotiate with АДРЕС_IP port 22: no matching key exchange method found. Their offer: diffie-hellman-group1-sha1

I google the error, I see a suggestion to enter the following command:

ssh -oKexAlgorithms=+diffie-hellman-group1-sha1 IP_АДРЕС

The response is [email protected]'s password:. That is, you can immediately say that the computer is needed, I just have the user anton. I enter the password - writes Permission denied, please try again.
Strange, the password is correct. Maybe you need to somehow configure the system before you can connect to it remotely?

Answer 1

In general, I solved this problem, and in the course of solving it, I learned that I need to look at the IP not on any sites, but in the ifconfig -a command. You will also have to generate private and public keys with the ssh-keygen command.
