FAQ Internet workstations
Anyone who has a valid student account at TU Wien or a special entitlement from TU.it (e.g. course or conference participant) can make use of this service. If you meet one of these conditions but still do not have a valid account, please contact the TU.it Service Center.
If the device is switched off, please switch it on by pressing the Power button (for some devices, the <SPACE> or mouse button is sufficient). After a short boot process, the login screen appears, where a kiosk mode in the intranet as well as a short help are available. If the system is in an undefined state, press <CTRL-ALT-DEL> or turn it off and on again.
For validation please enter your matriculation number (with leading "e") and the password of your student server account. If you have not deliberately changed it, it should be the same as your TU account. If you do not remember it, please contact the Service Center or reset it on the Student Services website under "Change Password", opens an external URL in a new window.
Once you have successfully validated yourself, you will soon find yourself on a graphical user interface, the so-called desktop. There you will find a taskbar and a start menu with applications for almost all important application areas.
If you want to use a mail client (Thunderbird is recommended), you must first set up your student mail account (as you probably did at home on your private notebook).
Primarily the most important Open Source applications for Mail, WWW, Office, Graphics, Science, Multimedia, as well as Software Development are available, see software of the workstations. A complete list by categories can be found in the start menu (button at the bottom left of the taskbar).
Windows applications under Linux are currently not offered.
There are currently some Windows computers on a test basis in the Gusshaus (above the Mensa and next to EI7).
You can store your personal data on a removable medium (e.g. USB stick) or in your home directory. In reality, this is not located on the local PC but directly in a separate directory called "LIZNG" in your home directory on the student server. The directory "My Documents" is on the same level and is only linked to the directory "LIZNG". If you always store your personal data there, they will also be visible in future LIZ system versions.
Please make sure that you never exceed your disk quotas, otherwise the login process will fail and error-free work will no longer be possible.
If you have selected "Local" when selecting the session, your home directory is not located on the server, but locally on the PC. Accordingly, your desktop and application settings are not available for this session, i.e. a local session is always started with the basic settings. In order to still be able to access your data on the server, however, you have the option of mounting your directory on the server under the virtual drive "HomeServer". We recommend this session method if there is a lot going on in the Internet rooms and a potential server overload would otherwise prevent you from working smoothly. Please note, however, that in a local session all the settings you have made are not retained and are not related to the settings of a normal session (home directory on the server). Please also keep in mind that your home directory is stored in memory during a local session and that very large downloads can therefore lead to system instability.
You can connect removable media (e.g. removable hard disks or memory sticks) with USB interface. Audio functionality can also be used via headphones (front connector). Please do not forget to unlock the medium before removing it (right mouse button "Unlock drive connection").
Home directories (2 GB) automatically connected to your student account are available to you for sessions on the computers in the TU.it Internet rooms. Here you can store all files that are created or downloaded during a Linux (LIZ) or Windows (WIZ) session.
It is possible to transfer files from and to the server home.student.tuwien.ac.at via SFTP (part of SSH) or SMB (Samba, CIFS). When using SCP clients, SFTP (or fallback to SFTP) must be set. Interactive access via the command shell is not possible. Access is restricted to the internal network of the TU Wien. A VPN connection is required from outside.
TU.it provides a virtual printer which allows easy access (without USB stick) to the Mobile Print Service of the Graphic Centre. Further information can be found at Druckservice GZ.
If you want to end your session, simply select "Logout" in the taskbar. After that, turn off the device ONLY if it hangs after the logout.
If you accidentally switch off the device during a running session, or are forced to do so due to a system error, it doesn't matter. You may lose some information if you have just opened a file or mounted a USB stick in which you have not yet saved any changes.
If you have not used the Linux system for a very long time (at least one year), it is possible that the version has changed considerably in the meantime.
If you have always saved your documents under the directory "My Documents", they should also appear in the current system under this directory. If, for example, you have stored them on the desktop, you may have to move these files manually to the new system. You may also have to reconfigure several applications. Please do not hesitate to contact the Service Center if you have any questions or problems.
Please also note that data in an old LIZ directory can burden your disk quotas and delete them as soon as you have transferred everything.
If you have problems logging in or working under Linux in general, you may have changed your settings so much that you cannot undo them in the normal way.
If the problem does not disappear after a reboot, sometimes only a manual repair or in the worst case a reconfiguration will help (create a file named .inithome in the home directory and then restart the session, or start a reinitialization/repair session right away). If the desktop is so inoperable that GUI action is no longer possible, this reconfiguration must be done in a local session without home directory on the server. If you are not 100% familiar with this procedure, please contact the TU.it Service Center immediately. Here the problem will be examined in detail, and only in hopeless cases will the home directory be reconfigured. Please also note that many individual settings are lost when reconfiguring, and a backup is therefore recommended beforehand.
Sometimes it can happen that the login still fails due to network or server overload despite the exclusion of all above mentioned causes. In such a case, a repeated login attempt - even on different devices - would only worsen the situation. The solution would be to proceed as follows: All PCs on which an unsuccessful login has been attempted must be rebooted (if this has not already happened), then wait about 5 minutes and then start a new attempt.
In rare cases, especially at times when there is a lot of activity in the internet rooms, it can also happen that the boot process takes a long time before the login. In this case, either patience is required or, if possible, the planned activities are postponed to a later point in time. Usually such problems only affect the boot process and not the session itself.
As mentioned earlier, it may not be possible to work without problems in high load situations. In this situation it is better to start a local session instead.
Please be so fair and leave your PC to other students after about one hour of work if there is a big rush (usually between 10:00 and 15:00). Please also make sure that you do not leave any valuables unattended if you have to leave your workplace for a short time.
