OpenSSH, a free and open-source SSH server, is a powerful tool for secure and encrypted communications between two untrusted hosts over an insecure network. It’s an essential tool for remote server management. This guide will walk you through the process of installing OpenSSH server on Ubuntu Linux.
Step 1: Open the Terminal Application
To start, open the terminal application on your Ubuntu desktop. If you’re working with a remote Ubuntu server, you’ll need to use a BMC, KVM, or IPMI tool to get console access.
Step 2: Install OpenSSH Server
Next, type the following command into the terminal to install the OpenSSH server: $ sudo apt-get install openssh-server.
Step 3: Enable the SSH Service
Once the OpenSSH server is installed, you’ll need to enable the SSH service. You can do this by typing the following command: $ sudo systemctl enable ssh.
Step 4: Start the SSH Service
After enabling the SSH service, you’ll need to start it. You can do this by typing the following command: $ sudo systemctl start ssh.
Step 5: Test the Installation
Finally, test the installation by logging into the system using the following command: $ ssh userName@Your-server-name-IP. Replace “userName” with your username and “Your-server-name-IP” with the IP address of your server.
By understanding and implementing OpenSSH, IT professionals can address issues related to security and network management. Efficiency is key in network management, and OpenSSH is one way to achieve it.
Remember, the right application of OpenSSH can lead to a more secure and manageable network. So, dive into the world of OpenSSH and unlock the full potential of your network infrastructure.
