FAQ: Remote Visualisation Troubleshouting

I forgot my VNC password

Don't worry - you can simply set a new password for VNC. Log on to the remote visualisation server and type

vncpasswd

Type a new password and verify it by entering it a second time. You will then be asked

Would you like to enter a view-only password (y/n)?

If you answer yes ("y"), you will be asked for another VNC password. You can give this password to co-workers, so that they can attach their PC to your VNC session, e.g. to discuss new results interactively. Your co-workers will see your desktop, but their inputs will be ignored.

I would like to have an environment for collaborative work - is that possible?

Yes, that's possible in VNC. But as the SuperMUC-NG policy prescribes non-sharing of user accounts, the preferred way would be to us just a local VNC session, and share screen via one of the many available video conferencing systems.

I want to use vglconnect

Only VNC connections via the login nodes are supported by the LRZ. If you want to use vglconnect, you have to establish an ssh-tunnel between your desktop and the remote visualisation server via one of the login nodes.

I'm sorry, but non of these questions describe my problem. How can I get help?
