For instructions specific to CHESS Remote Operations, please see RemoteUserGuide.

Options

CLASSE supports four versions of NoMachine. Please submit a ServiceRequest for help selecting or setting up NoMachine for your workstation or desktop.

LNX201

LNX201 is available through NoMachine as a general-use remote login node. Any CPU or memory intensive operations should be run on the CLASSE ComputeFarm or on individual workstations - not on lnx201.

NoMachine

The default version of NoMachine is available free of charge for the following use case.
  1. Only allows access to your physical display (not virtual desktops or individual applications).
  2. Must be on a CLASSE Network or connected to the ClasseVPN.
  3. Only allows one remote connection at a time.

NoMachine Enterprise Desktop

With a license purchase, CLASSE can install the "NoMachine Enterprise Desktop" on your desktop or workstation.
  1. Only allows access to your physical display (not virtual desktops or individual applications).
  2. Allows multiple simultaneous connections to a single desktop (although the owner of the desktop must be connected to approve the connection requests from other users).
  3. Does not require you to be on site or connected to the ClasseVPN.

NoMachine Workstation

With an additional license, CLASSE can install the "NoMachine Workstation" on your desktop or workstation.
  1. Allows connecting to both the physical display and creating up to four virtual desktops.
  2. Allows multiple simultaneous connections to a single desktop (although the owner of the desktop must be connected to approve the connection requests from other users).
  3. Does not require you to be on site or connected to the ClasseVPN.

Virtual Desktops

Depending on the version of nomachine installed on your computer, you may be able to create Virtual desktops in addition to controlling the physical display.

To start a full XFCE virtual desktop:
  1. start a connection to nomachine.classe.cornell.edu
  2. double-click on your desired computer
  3. click on the “New desktop” button (or double-click on “Create a new desktop or custom session”)
  4. double-click on “Create a new virtual desktop”
  5. Select desired display preferences. Good initial defaults might be “Show remote display at its resolution using scrollbars” and “Resize the remote display to match the client monitor” to should give you a nice full-screen display. Please see below for changing the display settings after starting a connection.

To kill an existing virtual desktop or custom session:
  1. start a connection to nomachine.classe.cornell.edu
  2. double-click on your desired computer
  3. right-click on the existing “virtual” session you see
  4. click on “Terminate”

Changing Displays, Resolution, etc.

Once the remote session to your desktop is open and running, to access the Menu Panel, enter the key combination Ctrl+Alt+0 or move your cursor to the red NoMachine icon and click on it.
