I want to restart an Ubuntu 18.04.4 LTS machine through ssh. I do not have physical access to that machine.
How can I make sure that the ssh service starts automatically on boot so that I can connect again after restart?
From a terminal run systemctl list-unit-files | grep ssh and if the service says enabled it should start back up when the system reboots.
$ systemctl list-unit-files | grep ssh
ssh.service enabled
[email protected] static
sshd.service enabled
ssh.socket disabled
And you can check the current status of ssh by running systemctl | grep ssh
$ systemctl | grep ssh
ssh.service loaded active running OpenBSD Secure Shell server
Hope this helps!
