Sometimes, we need to access our machine remotely, and that is where SSH (Secure Shell) comes into play. Enabling SSH Server on Ubuntu is straightforward, we just need to have openssh-server package installed which we can install by -
sudo apt-get update
sudo apt-get install -y openssh-serverTo check whether or not the SSH Server is running run -
sudo systemctl status sshsudo ufw allow sshssh {USER}@{MACHINE_IP}Note: In case ssh command is not available, one need to install openssh-client package.
