How can I pass on data to others?

Just copy them into the directory: „/student_share„. This directory can be written and read by anyone and is available on all machines. But be careful: it is emptied every day at midnight!

You also can use the FAUBox to exchange files. Every user who has an IDM account automatically has a FAUBox account.

How can I exchange data between Linux and Windows and vice versa?

The easiest way to do this is via the FAUBox to exchange files online within the web interface. Every user who has an IDM account automatically has a FAUBox account.

Where are my Windows files?

The RRZE offers each student 2 GB of storage space on a central Windows server. The same storage is used here.

How do I start Windows?

Windows can be started on a virtual machine if necessary. To do this, simply click on the Windows icon in the system tray. After it has booted, click anywhere on the window and log in as normal.
Attention: It is essential to shut down the Windows machine after the session has ended, otherwise Windows will start the next time that you are on the same computer with your login!

How can I find an overview of the installed programs in Linux?

Click on the white dots in the lower left.

Why can the trash no longer be deleted in Linux?

The RRZE offers a free network drive as a home directory with a limited quota (employees 10GB, students 2GB). This means that at no time can you use more than the permitted storage space on the network drive.

To free up memory that may be in use, please try the following troubleshooting approaches first (see also https://www.anleitungen.rrze.fau.de/?p=8644#quota-exceeded).

Note: If a graphical login is no longer possible, you can switch to the text console with Ctrl+Alt+F3 and carry out the steps given below. After completing the work, exit the text console with exit and switch back to the graphical login with Alt+F2.

  1. Empty rubbish bin/trash
    Empty the trash can by right-clicking on the corresponding desktop icon or by typing
    rm -rI ~/.local/share/Trash
    Explanation:
    Deleted files are moved to the so-called recycle bin for easy recovery. The storage space is not freed until the recycle bin is emptied.
  2. Clear cache directory
    Delete the .cache directory in your home, eg by entering
    rm -rI ~/.cache
    Explanation:
    Various programs temporarily store files here in order to speed up recurring access (e.g. web browsers).
  3. Analyze memory usage and delete additional files if necessary
    Create an overview of memory usage and find the biggest memory hogs by entering
    du -sh ~/{.[!.]*,*} | sort -h
    Explanation:
    The command creates a list of all files and directories in your home and sorts them in ascending order of memory usage. This way you can find out what is using up the most memory and it might be worth cleaning up.
    A notice:
    On Linux, hidden files are marked with a dot at the beginning. To make them visible in your file manager, you can use the shortcut CTRL+H.

Where is my Linux home directory and how much space do I have there?

Your home directory is on the CIP server cip-eeiww2.rrze.uni-erlangen.de. Everyone has space for 20 GB of data. Incidentally, a login on the server is not possible, nor is it necessary, since all the directories that are required are mounted in all other machines.

Where is my Linux home path? ‚cd /home‘ doesn’t work.

Your home directory will now be mounted in /home/<idm user ID>. The easiest way to do this is to simply type „cd“ with no parameters.
