First, and foremost you need a Java enabled WWW browser. The one, which you are currently using does not seem to support Java. You need either to download a more modern one, or reenable Java if it is disabled. Come back to this page once you have a working Java-enabled WWW browser.

This page provides remote access to your DonFTI Linux desktop. It is still in testing stage and a little rough around the corners. In particular, you will have to agree manually with the expired digital signature (the "warning" window will open immediately when you visit this page, press "Run") and enter your DonFTI login and password twice: first, to connect and second to actually log in to your desktop. Now, to connect enter your login, confirm the SSH key's digital signature (press "Yes"), and enter your password when prompted. After this a familiar welcome screen should open in a separate window, to which you may log in normally.
