Campus login

The image archive can be used with the Campus login, provided you have access to the IP address of a licensed campus network. Click the "campus-login" link, read and agree to the terms of use and press the Enter key or click the submit button.

After successful login you can use the image archive by clicking the buttons on the menu bar.

Your login status will be shown on the upper right hand corner of the screen, along with the logout button to leave the image archive at the end of your session.

Problems with the campus login?

If you have problems entering the image archive through the campus login, make sure that you are inside the campus network of a licensed institution. For the campus login to work, a set of IP addresses are registered with prometheus so that access from any of those addresses is granted.

In order for us to diagnose your problem with the campus login, please visit the following page and include its output in your support request: IP address information.

VPN connection

If you are connected to your institution's network through a VPN, you need to take into account that there are different methods of how such a connection can be set up. In order to access web sites outside of the institutional network (which the prometheus image archive most probably is), a method called "Full tunneling" has to be used. In other words, "Split tunneling" has to be disabled. It should be configurable from your VPN client. Please refer to your IT department's web site and/or documentation for details.

Here are a few resources that could be of help:

  • Tunneltyp Full- / Split-Tunnel - An explanation of the different tunneling methods (full vs. split tunneling) by the Regional Computing Centre (RRZK) of the University of Cologne. (German)
  • Was ist Split-Tunneling? - An explanation of "Split tunneling" and instructions on how to disable it for the Munich Scientific Network (MWN). (German)
  • Split tunneling - Technical details from Wikipedia, the free encyclopedia.
