SSH, also known as Secure Socket Shell or Secure Shell, is a cryptographic protocol that helps to encrypt communication in unsecured networks where an SSHD is the daemon program for SSH. Together they provide secure communication between two untrusted hosts over an insecure network.
Step 1 : To install it in Ubuntu, use the following command:
Install the public key on the server. Test authentication. Disable password-based authentication on the server. The remainder of this chapter will outline these steps in greater detail for Linux, macOS and Windows-based client operating systems. 1.4 Installing and Starting the SSH Service. The Default Ubuntu 20.04 server edition, do not have firewalld installed on it. You can simply run the following command to install required packages from default repositories. Sudo apt install firewalld After installation, start firewall service and enable it to auto-start on system boot. After installation, you need to set static IP for Ubuntu 20.04 and the Initial server set up on Ubuntu 20.04 LTS. Let’s check how to set a hostname, update and upgrade, add a sudo user, secure SSH, and install a firewall for Ubuntu 20.04 LTS.
Step 2 : You may check its status by running command:
Step 3 : We’re going to edit a /etc/ssh/sshd_config file using the vi editor as the root user, so you should type the following command on the terminal:
Step 4 : Look for a line that contains PermitRootLogin and replace it with the following line:
Openssh Ubuntu 20
Step 5 : Save the /etc/ssh/sshd_config file
Step 6 : Now it’s time to restart the SSH server. Then your server will be installed, configured, and ready to use. You can test this by executing the following command:
Step 7 : You can test your SSH server by trying to connect to it and typing on the terminal the following command:
Ubuntu 20.04 Allow Root Ssh
Step 8 : Now you will see a message asking for your authorization. Type yes and your password. You’re now connected to your our server through the SSH protocol.

Simplifying SSH connections with a config file
Step 1 : A local configuration must be stored in the .ssh directory of your home directory, and be named config. The full path would look something like this:
Step 2 : This file doesn’t exist by default, but if it’s found, SSH will parse it and you’ll be able to benefit from it. Go ahead and open this file in your text editor, such as nano:
Step 3 : This config file allows you to type configuration for servers that you connect to often, which can simplify the SSH command automatically, for example: Figma to wordpress.
