Enable SSH Server

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 -

Install SSH Server

$ sudo apt-get update
$ sudo apt-get install -y openssh-server

To check whether or not the SSH Server is running run -

$ sudo systemctl status ssh

Open port for SSH Server in Firewall

sudo ufw allow ssh

Connecting to SSH Server


Note: In case ssh command is not available, one need to install openssh-client package.
