Use VNC to connect to supercomputers

March 17, 2017

VNC advantages over X-forwarding:

• faster and responsive
• stable and established means of graphical remote control.
• consumes kB/sec instead of MB/sec.
• deliberately or accidentally disconnect, and when you reconnect, your VNC desktop is still there as it was.
• Wayland replaces X11, and Wayland does not forward over the network

How to use VNC to HPC:

1. RealVNC Viewer is free of cost.
2. Start VNC server on HPC
3. Connect to VNC server using its IP address
