Install OpenSSH Server
From this point forward, I'd recommend you have a ssh server running. It may make it easier to work and debug problems, especially when working with remote machines as necessary.
For a Live CD based installation your will have a graphical interface available to you to enable all of the extra Ubuntu repositories.
Click on System. Choose Administration. Choose Synaptic Package Manager. Search for openssh. Click on openssh-server to mark it. Press the apply button, and it will be installed.
