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
