There are few things we should do after a fresh install of Fedora 23 Server. As my standard steps after installing server is to make sure that the SSH server is enabled on the server. SSH server enables us to connect to the server remotely via SSH protocol. By default, ssh server package is already installed on Fedora 23 Server but its not enabled.
To enable the ssh server on Fedora 23, use this command:
systemctl start sshd.service
Now check if the sshd service is up and running
systemctl status sshd.service
It should returned the following information:
To restart ssh service, you can use the following command
systemctl restart sshd.service
Now, you can start connect and manage your Fedora 23 Server remotely.
