In this post I will show how to install OpenSSH on it, so that we no longer need the iDRAC for system administration. Connecting to the installer over SSH. If the only available terminal is very basic, an alternative is to connect via SSH. If the network is up by the time the installer starts, instructions are offered on the initial screen in basic mode. Otherwise, instructions are available from.

In Ubuntu 18.04 server, SSH server is an option during the installation process and your Ubuntu system probably has the OpenSSH server installed already. If you are not sure, run the following command to check whether you have SSH server installed already.
If you see openssh-server in the output, SSH server is installed already. Otherwise, you can install openssh-server package with following command:
After you’ve installed the openssh-server package, check the status of the ssh service with the systemctl command:
The status should be active (running), if not run following two commands to start and enable the ssh service:
You can also run the ss command to make sure that the Ubuntu system listen on TCP port 22.
If the Ubuntu firewall is enabled, you need to add a firewall rule that allows TCP port 22 inbound.

Connecting to the Ubuntu via ssh command
The ssh command is a command line SSH client available in every Linux/Unix operating system. It is a very simple and easy to use SSH Client for Ubuntu Linux.
To connect to that server via SSH, execute the ssh command followed by the IP address or domain name of the Ubuntu server:
Or
The ssh command by default will try to log in to the remote server with the same username you are using on your local Linux machine. For example, if you have logged in to your local Linux machine as a root user, then the ssh command will try to connect to the remote server as the root user.
If you want to login as a different user, use the -l option:
Alternatively, you can also use the following format (username@ip-address):
On windows you can get SSH command by installing the GIT bash shell or you can use an SSH client like Putty.
