Why can't I connect via SSH (via Putty) to the local computer?

Question

SSH

Putty throws a "putty network error connection refused" error window when trying to connect to the local machine (with ubuntu). What is the problem?

Answer 1

Summarizing the above (and a little gag) - open the terminal and execute the commands. On the second command, he may ask for a password, this is normal, we try to enter our own. If it didn’t fit, then we are looking for the one who installed ubuntu and continue to torture him :)
1. Check if the processes actually have an SSH server.
If we see only this command in the output, set OpenSSHd
. then we try to run
If it does not appear, then the output of the following commands to the studio:
2. If the output of ps aux contains something like /usr/sbin/sshd -D, then
If there is not 0.0.0.0:22, but, for example, 0.0. 0.0:2222, then we change the port in PuTTY to 2222 (and you can also fix it in sshd_config, but that's later)
If everything is OK, then the firewall remains
and output to the studio

Answer 2

Well, probably not installed OpenSSH Server. By the way, why putty when there is an ssh command!

ssh [email protected] -p [specify port]

Answer 3

Connection refused - connection refused. This error usually occurs if no one is accepting connections on the other side, for example, the ssh service is not running.

Answer 4

By local computer in this context, I mean connecting to myself. If you can't connect to 127.0.0.1, you don't have the sshd daemon running, or very crooked iptables rules that need to be demolished.
