-Update Your System: Before installing any new software, it’s a good practice to update your system’s package list and upgrade the existing packages to their latest versions.

-   $ sudo apt upgrade
-This ensures that you have all the latest security patches and software updates, reducing the risk of vulnerabilities.
-Install OpenSSH Server: With your system updated, the next step is to install the OpenSSH server package. This package contains the necessary software to run an SSH server.
-   $ sudo apt install ssh
-Once installed, the SSH service will start automatically. However, it’s always a good idea to verify that the service is running properly.
-Enable SSH Service to Start on Boot: To ensure that the SSH service automatically starts after a reboot, you need to enable it using systemctl.
-   $ sudo systemctl enable ssh
-This command configures the system to start the SSH server automatically whenever the system boots up, ensuring that remote access is available after restarts without manual intervention.
-Verify SSH Service Status: To check the SSH service’s status and confirm that it’s active and running, use the systemctl command.
-   $ sudo systemctl status ssh
-If the service is not running, you can start it with the command:
-   $ sudo systemctl start ssh
-This step ensures that the SSH server is operational and ready to accept connections.
-Configure Firewall: If you are using the UFW firewall, it’s necessary to configure it to allow SSH connections. This step is crucial for remote access, especially if you’re operating in a protected network environment.
-   $ sudo ufw allow ssh
-   $ sudo ufw enable
-This command configures UFW to allow inbound SSH connections, ensuring that remote attempts to connect to the server via SSH are not blocked by the firewall.
-Connect to Your Ubuntu Machine via SSH: With SSH enabled and the firewall configured, you can now connect to your Ubuntu machine from another computer using SSH.
-   $ ssh username@your_server_ip_OR_hostname
-Replace username with your actual username on the Ubuntu system, and your_server_ip with the IP address of your Ubuntu machine. This allows for secure remote access to your system.
