1. Software Requirements

A class of Interactive Apps (Plugins) will need a VNC server on the compute node (e.g., the Desktop app). This requires the following software to be installed on the nodes that the batch job submitted by the Interactive App is meant to run on, NOT the OnDemand node.

For VNC server support:

• nmap-ncat
• TurboVNC 2.1+
• websockify 0.8.0+

Warning

Do NOT install the above software on the OnDemand node. The above software requirements are ONLY for the compute nodes you intend on launching Desktops on within batch jobs.
