===== SoCS NoMachine Graphical Linux Environment ======

nomachine.socs.uoguelph.ca is a Graphical Linux environment, available remotely for SoCS stuents. When logged in you will have access to the same servers as linux.socs.uoguelph.ca but with a graphical desktop interface.

==== Setting up the Connection - One Time Only ====

NoMachine client software is required to connect to the SoCS Graphical Linux environment. To install and connect for the first time, follow the instructions below.

- Download the NoMachine Enterprise client, available here [[https://www.nomachine.com/download-enterprise#NoMachine-Enterprise-Client|NoMachine Enterprise Client Download]]. Choose the correct client for your operating system (See Image 1 below) and install.
  - Open the client. In the top right, click New (See Image 2 below).
  - Ensure "NX" is set as the protocol (it is the default selection), and click Continue.
  - Enter **//nomachine//.socs.uoguelph.ca** for the Host. Leave the defaults selected.
  - Choose Password as the authentication type and hit continue.
  - Choose Don't use a proxy and click continue.
  - Name should be something to identify the connection by. Accepting the default of Connection to nomachine.socs.uoguelph.ca is ok, but you may choose something more memorable.

==== Connecting ====
The following instructions are used to connect to the server, and will take place each time.
  - After opening the NoMachine Client, the connection you created in the earlier section should be listed. Double click, or select and Choose Connect (See Image 3 below).
  - If you are asked to "Verify host authenticity", press "Yes". Otherwise, continue to the next step.
  - Enter your Central Login username and password and choose ok.
    * Optionally, you can tick the checkbox to save the password for future connections, which will skip this step on future connections.

==== Logging Out ====

There are two ways to log out of the SoCS Graphical Linux Environment.
  * The first option is to click on the applications menu, and choose "log off". This closes all programs and logs you out from the computer.
  * The second option is to click the red X at the top of the screen. This brings up a menu to either "Disconnect" or "Terminate". Terminating is closing all programs and logging off as in the first options. Disconnecting allows your session to be available for up to 6 hours allowing you to leave your programs running. Please be respectful of others logged in and only choose Disconnect if you plan to return soon.

==== Changing Display Size ====
  * To enter the display menu, click the NoMachine menu (red button) on the taskbar inside the NoMachine window, and choose "Show the menu panel". **Alternatively**, you can use the keyboard shortcut CTRL + ALT + 0 (zero) to access the menu.
    * Clicking on the "Resize Remote Screen" button will automatically resize the size of the NoMachine desktop to fit the window. This will remove scroll bars from NoMachine
    * Clicking "Full Screen" will automatically change NoMachine to be full screen on your local computer.
