How do I get a GUI or desktop environment remotely for the Linux machines?

By using NoMachine.

All CADE Lab Linux machines are running NX Server. This allows you to open a desktop connection similar to VNC without the need to start a separate VNC server session. To connect you will need to install the NoMachine client on your local machine. Clients are available for Windows, OS X, and Linux.

The configuration for remotely connecting to CADE using NoMachine can be found here.

What remote machine or what’s the full name to connect to?  See this page.
