Work Environment:

The Classroom Computing Environment is a so-called Virtual Desktop Infrastructure which simulates a Linux desktop machine on your Thinclient or within your browser. Depending on course requirements, you will be working on a specific Linux distribution (SLC6, CentOS, Ubuntu etc.) with all necessary software for the course installed. Please note that due to the nature of the setup, graphics rendering will not perform as well as on an actual desktop or laptop computer.

From within the environment, access to addresses outside its own network is restricted to HTTP and HTTPS.

Home Directories and Shares:

Each user has a home directory in /user which is only accessible to them.

While you are connected to the Classroom Computing Environment an additional shared folder is available at /data. This share can be used to store and retrieve course materials and other files as necessary.

This folder can also be accessed from within the nikhef linux network or the login servers ( & To do so, simply execute 'cd /data/course' and the folder will be mounted to your filesystem (might take a few seconds).

Access to the subfolders of that share depends on membership in the respective course group(s).
