systemctl status ssh.service

You can exchange status In code stop, reload, restart Stop, reload, or restart the service.

3. The SSH service is now ready for use. If you want to change the listening port, root login permissions, or any other authentication, run the command to edit the configuration file.

sudo nano /etc/ssh/sshd_config

Replace nano When gedit If you are using Ubuntu desktop.

Press Ctrl + X, Y to save your changes and finally press Enter. And don’t forget to restart the SSH service sudo systemctl restart ssh.service command.
