That’s great. Finally, you decided to have Ubuntu for your desktop OS?

Now one question might be bothering you..!

How do I install the OpenSSH server on Ubuntu/Linux?
For Ubuntu beginners, this quick tutorial of Scopehosts will show you how to enable the SSH(Secure Shell) service on Ubuntu 18.04.

When establishing a remote connection between the server and a client, the prime concern is ensuring security for the server. For Linux/Ubuntu users, the best practice of managing & accessing the server remotely is through the cryptographic protocol known as Secure Shell (SSH).

Firstly, Let’s discuss on SSH

SSH(Secure Shell) — The cryptographic network protocol that encrypts all the data been transferred from one machine to another, making sure that no sensitive information is compromised during the process.

As a desktop client, you can safely run a command line, transfer files, secure network services, and much more.

Prerequisites

Before you begin the installation, you need to be logged in as a root user or a user with sudo privileges.
Permissions to ...
... access the remote computer.
OpenSSH 7.5 or higher version
Access to a terminal/command line
Steps For Enabling SSH on Ubuntu
Step 1: Open terminal using Ctrl+Alt+T or Windows button on the keyboard followed by alphabet t and hit Enter or by searching for “Terminal” from software launcher.

Step2: Execute the following commands on terminal

**$ sudo apt update**
**$ sudo apt install openssh-server**
Enter the password when prompted and hit ENTER. Type Y to continue with the installation process.

Step3: The installation is completed, to check that ssh was successful use the below command

**$ sudo systemctl status ssh**
The confirmation message that you are looking for is: Active: active (running)

Press q to get back to the command line prompt.

Step4: You are done with the installation, you can connect through Linux and macOS systems as they have SSH installed by default, for windows you can access it by downloading PuTTY.

Configure OpenSSH:
To change the SSH setting, e.g., run command, root access, listening port:

**$ sudo gedit /etc/ssh/sshd_config**
The command opens the configuration file via Gedit (For Ubuntu Server, you may use nano instead).

And remember to restart SSH service to apply changes:

**$ sudo systemctl restart ssh.service**
Note: By default, SSH listens on port 22. Changing the default SSH port adds an extra layer of security to your server by reducing the risk of automated attacks.
