How To Install SSH Server on Ubuntu 22.04 LTS

In this tutorial, we will show you how to install SSH Server on Ubuntu 22.04 LTS. For those of you who didn’t know, OpenSSH is the premier connectivity tool for remote login with the SSH protocol. It encrypts all traffic to eliminate eavesdropping, connection hijacking, and other attacks. SSH is not installed or enabled on your Ubuntu 22.04 LTS system by default.

This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the SSH Server on Ubuntu 22.04 (Jammy Jellyfish). You can follow the same instructions for Ubuntu 18.04, 16.04, and any other Debian-based distribution like Linux Mint.

Prerequisites

• A server running one of the following operating systems: Ubuntu 22.04, 20.04, 18.04, and any other Debian-based distribution like Linux Mint.
• It’s recommended that you use a fresh OS install to prevent any potential issues.
• SSH access to the server (or just open Terminal if you’re on a desktop).
• An active internet connection. You’ll need an internet connection to download the necessary packages and dependencies for OpenSSH.
• A non-root sudo user or access to the root user. We recommend acting as a non-root sudo user, however, as you can harm your system if you’re not careful when acting as the root.

Install SSH Server on Ubuntu 22.04 LTS Jammy Jellyfish

Step 1. First, make sure that all your system packages are up-to-date by running the following apt commands in the terminal.

sudo apt update
sudo apt upgrade

Step 2. Installing SSH Server on Ubuntu 22.04.

By default, OpenSSH is available on Ubuntu 22.04 base repository. Now run the following command below to install the latest version of the OpenSSH to your system:

sudo apt install openssh-server

Once the installation is completed, let’s ensure the service of the OpenSSH is running:

sudo systemctl enable ssh
sudo systemctl start ssh
sudo systemctl status ssh

Step 3. Configure Firewall.

You may need to allow SSH connections coming from client systems in the firewall. So, use the below command to create a rule for allowing SSH connections from external machines:

sudo ufw allow ssh
sudo ufw enable
sudo ufw reload

Step 4. Accessing Ubuntu 22.04 via SSH.

With SSH now installed and enabled, you can connect to a remote system, another remote PC, or a server. You can connect to your system via SSH using Putty from Windows or built-in SSH clients from Linux or macOS:

ssh user@your-server-ip-address

For example, if your user is root and server-IP-address is 192.168.77.22, the command will be:

ssh root@192.168.77.22

Congratulations! You have successfully installed the SSH Server. Thanks for using this tutorial for installing the SSH Server on Ubuntu 22.04 LTS Jammy Jellyfish system. For additional help or useful information, we recommend you check the official OpenSSH website.
