Installing SSH Server on Ubuntu 22.04 LTS


An SSH (Secure Shell) server is a software application that enables secure remote access to a computer or server over a network. It allows users to establish encrypted and authenticated connections to the server, providing secure remote administration and file transfer capabilities.

In this post, We will show you how to install SSH server on ubuntu 22.04 LTS

Step 1: Run System Updates

Update the package lists to ensure you have the latest information about available packages. Run the following command:

sudo apt-get update

Step 2: Installing SSH Server

Once the package lists are updated, you can proceed to install the OpenSSH server package by running the following command:

sudo apt-get install openssh-server -y

Step 3: Check SSH Service

After the installation is complete, the SSH server should start automatically. You can verify the status of the SSH server by running the following command:

sudo systemctl status ssh

If the SSH server is running, it will display the “active (running)” status.

Step 4: Generate SSH Key Pairs

By default, the SSH server allows login using password-based authentication. However, it is recommended to use key-based authentication for better security. If you don’t have SSH key pairs set up, you can generate them by running the following command:

Step 5: Remotely Access

You can now remotely access your Ubuntu system using SSH. Use an SSH client (such as OpenSSH on Linux/macOS or PuTTY on Windows) and connect to the Ubuntu system’s IP address or hostname.

ssh username@

Replace username with your actual username on the Ubuntu system.

When connecting for the first time, you may see a warning about the authenticity of the host. Verify the fingerprint of the SSH server and confirm the connection to proceed.

Once the connection is established, you will have remote access to your Ubuntu 22.04 LTS system via SSH. You can execute commands, manage files, and perform administrative tasks as needed.
