Connect to the ECC Linux platform using the graphical interface

NX Workstation

NX Workstation is a remote access method allowing graphical access to Linux systems in the Engineering Computing Center (ECC) in a secure and bandwidth-efficient way. It supports hardware accelerated 3D rendering and hardware accelerated encoding/decoding.

Pre-requisites for remote access

Duo: You will need to have Duo set up. If you already have Duo set up, skip to step 2. If you do not have Duo set up yet, follow the instructions in the Duo Setup Quickstart.
VPN: Next, you will need to download and install the SCU VPN client. Connect to the VPN before you remotely access the ECC. If you do not have the VPN set up yet, follow these instructions.
SCU Username and Password: Use your SCU Username and Password to connect to the ECC.
OnGuard: To access the ECC from eduroam, your computer must have OnGuard installed and pass all the security checks. To install OnGuard and make sure your computer passes the security checks, follow these instructions.

Preparation

You must first download and install the NoMachine Enterprise Client software on the computer you're connecting from:

Connecting

Download the connection file: Connection File download site (access is limited to SCU)
Save the file somewhere easy to remember (like your Desktop or Documents folder)
Unzip the downloaded file
Double-click on the ECC-NX-Linux.nxs file
On your first connection, you will be prompted to trust the key of the NX server
Enter your SCU username (SCU Gmail without the @scu.edu) and password when prompted
Select "Create a new virtual desktop" and click "Continue"
On your first connection, NX will display up to three help screens overlaid on top of the Linux desktop, click OK on each to move on
When the desktop is displayed, it may be smaller or larger than desired, simply resize the NX window to the size you want and wait for the Linux desktop to resize itself to match
- If the display remains too small or cut off:
  - Put your mouse in the upper-right corner of the NX window (where the Linux date/time display is by default)
  - A small "edge of page folding down" animation will appear.
  - Click it.
  - Select "Display"
  - Click "Resize remote screen" to put the selection box around it ("Fit to window" will grey-out)
  - Click "Done" twice
  - The Linux desktop should now auto-size itself to fit in your NX window
