Hi Chris,

Gareth pointed me to this thread - you might be interested in the open source project we have in current development

Currently being used on our HPC system

If you want to give it a whirl drop me an email paul dot mcintosh @ monash do edu

> I am working on a method to provide easy remote VNC access to cluster
> nodes using regular torque "qsub" job submission. The objective is to
> allow cluster users to run GUI based software (eg. matlab, visit,
> paraview, etc.) on cluster nodes via remote access. We have run into
> several practical difficulties not directly related torque.
> For example, users submit jobs on a public-facing server but the VNC
> service starts on a cluster node on a private network. We need to
> create a network path between the remote user and the cluster node,
> using the public-facing server as the intermediate bridge. We have
> found no good method to automate this as part of the job submission. We
> tested various port forwarding schemes that require manual intervention
> but nothing that is fully automated.
> Another issue is VNC traffic is unencrypted. We would like to encrypt
> traffic (ie. using a SSH tunnel) to the remote user. However,
> installing and configuring the required VNC & SSH client software on a
> remote PC is a support nightmare (eg. supporting unmanaged windows, mac
> & linux desktop & laptops).
> Does any manage a cluster where users submit jobs to use VNC ?
> Are you able to fully automate the VNC setup and connection ?
> Any advice on avoiding common pitfalls ? Is a fully automated VNC
> service unrealistic ?
