Installation of ssh server on linux
Raw
linux ssh.md

Install ssh-server

# sudo apt-get update # sudo apt-get install openssh-server

See status: # sudo systemctl status ssh

Backup the ssh configuration: # sudo cp /etc/ssh/sshd_config /etc/ssh/sshd_config_backup

configure the ssh server: # sudo nano /etc/ssh/sshd_config

Warning On ubuntu 22.10 SSHd now uses socket-based activation.

On upgrades from Ubuntu 22.04 LTS, users who had configured Port settings or a ListenAddress setting in /etc/ssh/sshd_config will find these settings migrated to /etc/systemd/system/ssh.socket.d/addresses.conf. As an exception, if more than one ListenAddress setting is declared, the configuration is not migrated because systemd’s ListenStream has different semantics: any address configured which is not present at boot time would cause the ssh.socket unit to not start.
