Installing and configuring SSH service in Ubuntu is very easy, just follow these steps:

  1. Install SSH service:
    Open the terminal and enter the following command to install SSH service:
sudo apt update
sudo apt install openssh-server
  1. Setting up SSH service:
    Once the SSH service is installed, it will automatically start up by default, and the configuration file is located at /etc/ssh/sshd_config. You can edit this file as needed to configure the SSH service.
sudo nano /etc/ssh/sshd_config

In the configuration file, you can modify settings such as the port number of the SSH service, allowed users, login methods, and key authentication.

  1. To restart the SSH service:

    After modifying the configuration file, it is necessary to restart the SSH service in order for the changes to take effect. Enter the following command to restart the SSH service:

sudo systemctl restart sshd

The SSH service is now installed and configured. You can now connect to the Ubuntu host using an SSH client.
