Chad's lesson was an overview of logging into a local system via graphical mode (i.e. a server, desktop or local virtual machine running a GUI) as well as how to connect via a console (SSH to a remote system like our cloud servers). This was more a discussion about what those looked like and the differences of each method.
An additional method, using VNC to a Raspberry Pi, was also demonstrated, but again was a local system for that lesson. You DO have the ability to log in via VNC to the CentOS 7 cloud servers we have provided for you via the drop down menu you used to launch the server. Once it is started, you will see another option 'open VNC web console' in the drop down box next to that active server. At that point, you will see a graphical environment that will be similar to any GUI on any Linux distribution.
Terrance yes the lesson was to demonstrate how to VPN into another machine from the UI of a CentOS 7 system. The CentOS 7 plain image did not contain the same set of tools in the UI as Chad's lesson did, hence my question. Anthony James seems to have answered it though. I will test his advice and make sure it is true.
