SSH-connection to the CIP-Pool PCs

All CIP-Pool PCs can be connected to, using Secure Shell (ssh) from the Internet. You can log onto, as well as the clients, e.g., provided the respective client is up. This gives you access to your data and enables you to use applications (e.g. maple) from anywhere.


Remote access is activated for all physics students and physics employees. Everyone else please ask for remote access with a short message to Please include the reason, why you need remote access, and the Id given to you from the Rechenzentrum.
