Setting up Remote Access with SSH

Whether you’re developing on a local machine with a desktop or on a headless server in the cloud, remote access will come in useful. Most cloud-hosted servers will already be set up with SSH and a user account. If not, here’s how to install it:

sudo apt install openssh-server

Setting up the Firewall with UFW

UFW (Uncomplicated Firewall) is a simple firewall that will help keep your server safe. Leaving a server wide-open to internet traffic is a certified bad idea. Even if you are running a server on your home network, it’s a good idea to have a firewall set up so you’re familiar with the process.

Install UFW:

sudo apt install ufw

Allow SSH through the firewall:

sudo ufw allow OpenSSH

This will allow both incoming and outgoing traffic to SSH from the server while the firewall is enabled. Enable the firewall by running:

sudo ufw enable
