Printing

The print job is simply discarded by the system without warning if you select the remote printer. You can only print to the associated printer on site. In the CIP pool EEI you print to cipeeiww-e-technik-utax-5058i and in the CIP pool WW to cipeeiww-wwlas1-utax-4062i.

This is excluded for data protection reasons.

At the moment, printing in the CIP pool is free. We ask that you use printing responsibly and economically, otherwise the service will have to be discontinued.

In the CIP EEI: cipeeiww-e-technik-utax-5058i

In the CIP WW: cipeeiww-wwlas1-utax-4062i

When starting for the first time after a new installation, Windows does not yet know the printer. Just restart Windows again and the printer should be there.

Check if the multi-sheet feeder is open on the printer. Restart the print job. Contact us if the problem persists.

You want to print out a PDF? There are always some files that were created incorrectly and do not follow the rules exactly. Linux cannot cope with that. So try to print them out with Windows. Use the FAU Box to exchange the files or download it again.

Can I print in CIP EEI on CIP WW and vice versa?

Can I see who is in the printing queue in front of me?
This is excluded for data protection reasons.
Printing without charge
At the moment, printing in the CIP pool is free. We ask that you use printing responsibly and economically, otherwise the service will have to be discontinued.
What is the name of the correct printer?
In the CIP EEI: cipeeiww-e-technik-utax-5058i In the CIP WW: cipeeiww-wwlas1-utax-4062i
Why has Windows no printer?
When starting for the first time after a new installation, Windows does not yet know the printer. Just restart Windows again and the printer should be there.
Why is the printer always asking for missing paper in the multipurpose tray?
Check if the multi-sheet feeder is open on the printer. Restart the print job. Contact us if the problem persists.
Why is there only garbage on the printout?
You want to print out a PDF? There are always some files that were created incorrectly and do not follow the rules exactly. Linux cannot cope with that. So try to print them out with Windows. Use the FAU Box to exchange the files or download it again.

Tips

You can access the computers graphically via a remote desktop connection. You can find instructions here: Establishing a remote desktop connection to the CIP pools EEI and WW.
If you only need one terminal, you only need to be connected to the FAU network via VPN and establish a connection to any CIP computer. You can find the DNS names or IP addresses here: https://www.eei.tf.fau.de/cip/ausstattung/#collapse_0

Open a terminal and enter the following command:

testquota <return>

A window opens showing you how much data you have and where your big memory files are.

The easiest way to do this is via the FAUBox to exchange files online within the web interface. This allows you to exchange files between yourself and others. Every user who has an IDM account automatically has a FAUBox account.

If you are logged in locally, at the bottom left in the circle with the 3 dots. Otherwise, you can also click at the top left and enter the name of the program you want. If it is installed, it will be displayed.
With Remote Desktop at the top left under „Applications“.

Just copy them into the directory: „/student_share„. This directory can be written and read by anyone and is available on all machines. You can also create subfolders there. 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.

In order to be able to run a script longer without staying logged in, the runtime of the Kerberos ticket must be extended. The Kerberos ticket is an automatically created element after login, which verifies the successful login of the user. For security reasons, the status of the ticket must be updated by logging in again or by unlocking the display after at least 10 hours with the user password, otherwise all of the user’s processes will be terminated. With Linux commands on the command line, the runtime can be increased to up to 7 days.

The whole thing only works if you log in locally or via ssh. It does not work via Remote Desktop (rdp).

Precise instructions can be found here from the RRZE (german language):
https://www.anleitungen.rrze.fau.de/betriebssysteme/linux/anbindung-an-die-kerberos-infrastruktur-des-rrze/kerberos-und-langlaufende-prozesse/

Windows can be started on a virtual machine if required. To do this, simply click on the Windows symbol in the taskbar on the left. Unfortunately, Windows cannot be operated under Remote Desktop for licensing reasons. After it has started up, click once in the window and log in with your idm access data.
Important: Be sure to shut down Windows again after the session ends, otherwise Windows will be active for the next user with your login data.

Have you emptied your trash regularly? Empty it and you will usually have space again.

If you need a quota larger than 50GB, write an email to the CIP supervisor with a desired size and a short argument. Then we can increase the space.

The RRZE offers each student two GB of storage on a central Windows server. This is also used in the virtual Windows and integrated automatically.

If you are logged in locally, there is a shutdown symbol in the top right. Click on this. In the small window that opens, there is the same symbol again in the top right. Please click on this and then you can click on „Log Out…“ to log off.
If you are connected via Remote Desktop, click on your name in the top right and then on „Log Out…“ to log off.

Your home directory is on the CIP server cip-eeiww2.rrze.uni-erlangen.de. Each user has 50 GB of storage space. It is not possible to log in directly to the server via the console. Nor is it necessary, as all paths are mounted automatically. The path is: /home/eeiww/#idm-Kennung#/

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

The RRZE offers a free network drive as a home directory with a limited quota (50GB). 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.

If these steps do not help you, please contact us again for a more detailed analysis of the problem.

Then you don’t have a print account yet. Just click away. It’s normal and no big problem. If you have a print account, a window with the current account balance will appear instead.

Maybe this error message appears: „… always running“. In this and any other cases open a console and enter the following commands:

Warning: any bookmarks will be lost and Firefox will be completely reset to the default settings.

cd <return>
rm -r .mozilla <return>

After logging out and back in, it should work again.

Can I access the computer from outside?
You can access the computers graphically via a remote desktop connection. You can find instructions here: Establishing a remote desktop connection to the CIP pools EEI and WW. If you only need one terminal, you only need to be connected to the FAU network via VPN and establish a connection to any CIP computer.
