The Institute of Electrical Engineering and Information Technology has two computer pool rooms in P22.214.171.124 and P7.2.02.1, equipped with 22 respectively 24 computers running under GNU/Linux. Furthermore, it is possible to plug in private notebooks in both pool rooms or to use the study corner in P7.2.02.1. In addition, there is a learning center for electrical engineering in P1.7.09.3, which is supervised by the department of technology didactics and offers space for self-study or exchange and collaboration with fellow students. There is also the possibility to connect private notebooks to a power outlet.
The pool rooms can be used by all institutes of the faculty for exercises and seminars that require the use of computers. Interactive whiteboards are available for teaching purposes. In this context, events of the institute EIM-E have priority of use over EIM-I/M. In addition, the pool rooms are available to all students of the faculty for "free practice" during regular building opening hours.

- Rules of use (Status: 23.07.2019)
The following rules, which are actually self-evident, must be observed when using the pool:
- Never disconnect computers or monitors from the mains!
- Smoking, drinking or eating is not allowed in the pool room.
- All actions that could disturb other persons in or outside the room must be refrained from. This also includes the dissemination of pictures, texts or sounds of annoying content or volume.
- The furnishings are to be treated properly and protected from damage or theft.
- Precautions must be taken to ensure that the room or its furnishings as well as the software on the computers cannot be used by unauthorized persons. For this purpose, among other things, the password for computer access must be carefully selected and kept secret.
- The windows and doors of the pool rooms are to be locked tightly when leaving and the whiteboards are to be left wiped clean.
- Any abnormalities, damage, etc. are to be reported immediately to the pool room supervisor.
- Attacks on other computers and users (spying out/altering data) are prohibited. Even the attempt is to be refrained from.
- Software provided on the computers in the pool may not be misused, copied or changed. Unless this is expressly permitted in individual cases. The applicable copyright regulations must be observed in all cases.
- The electrical equipment and connections must not be damaged or disturbed.
- When accessing the Internet, the "Netiquette" announced there shall be considered part of these regulations.
- It is forbidden to misuse existing security gaps in the installed software or the fundamentally existing security deficiencies of the Internet. Above all, it is forbidden to use network services under a false name.
- Network access may not be misused for advertising purposes or for criminal acts.
- Violations of these rules will result in the revocation of the user's authorization. Further civil or criminal prosecution of violations is hereby not excluded.
- The pool administrators may pass on user data to others for the purpose of prosecuting violations of these rules.
Equipment and possibilities of use
- Room equipment
- 21 computer workstations on GNU/Linux basis in P7.2.02.1
- 23 computer workstations on GNU/Linux basis in P22.214.171.124
- one teacher's computer each based on GNU/Linux
- interactive whiteboards, which can be used interactively via a Windows8 computer or as a pure presentation surface via a teacher's PC or a notebook brought along.
- Learning corner with whiteboard (P7.202.1 only)
- Usage times
In principle, room access is always possible via the magnetic card+PIN, which are given to the user when creating the login. However, the opening hours of the P-building should be observed:
Monday - Friday: 07:00 - 21:30
Saturday: 07:00 - 13:00 hrs
The P-building is closed on Sundays and public holidays.
Please make sure that all windows are closed before leaving the room!
- Conditions of access
The rooms are available to all students of the faculty EIM. An IMT-Login is required as well as an electronic access card to enter the rooms. Access cards will be issued by the IRB in the Guru-Room with the IMT login provided.
The following requirements must be met when applying for the access card:
- One must have an IMT login and be able to present a student or employee ID.
- In the IMT user administration, the service "Netzwerkspeicher" must be activated.
The IMT:Media service center in H1.201 is responsible for issuing media locker keys to teachers. Keys are only issued during service hours and usually require the presentation of an employee ID.
- Software equipment
On the workstations in the room there is a GNU/Linux installation based on Debian GNU/Linux. As a basis the installation of the RBM (Rechnerbetrieb Mathematik) is used, which contains numerous extensions and adaptations of the distribution for the optimal use in the faculty. (Examples for this adaptations the integration of Matlab, Maple, Openoffice, KDE in in each case current versions).
Short-term adaptations to user wishes, which arise for example through courses, are usually possible, since a separate installation server is available for the pool.
Furthermore, the workstations can be used as thin clients in connection with EIM-I servers, in order to enable the use of the pool in the computer science environment for computer science courses.
The interactive whiteboards are operated via separate Windows8 computers, which are mounted on the whiteboards and on which one can log in with one's IMT login.
- Projector use
There is an interactive whiteboard with a projector in both pool rooms. The projector can be operated either interactively via the Windows8 computer directly at the whiteboard. The special input pen and a wireless keyboard are located in the media cabinet for this purpose, as is the remote control for the projector.
Alternatively, the projector can be controlled from the respective teacher's computer or from a notebook computer brought along. In order to be able to implement these different connection combinations, there is a switchbox in each of the media cabinets, which is used to set which input is routed to the respective projector. In P7.202.1, there is also an older ceiling projector that is also integrated into this system.
On the switchboxes there are two buttons: A and B. By pressing e.g., button A several times, it is possible to select which of the four possible inputs (1 to 4) will be switched to output A.
The following diagrams explain how which inputs can be switched to which projector via the switchbox. Printouts of these diagrams can be found on the media cabinets and in the download area.
- Remote access
File access to the home directory
Each IMT access is assigned a storage quota, which also contains the home directory that is used on the pool room computers. This home directory can also be accessed from outside the university. How to do this is described here.
Under Windows the program FileZilla can be helpful, under Mac OS you can access your home directory directly with the Finder (press Apple-K!) and under GNU/Linux directly from the command line with the command scp.
The required specifications are:
- Server: sftp://afs-gate.upb.de
- username: IMT-USERNAME
- Password: IMT-PASSWORD
Remote access to individual computers
The pool room computers can be used remotely within the operating hours (Monday - Friday: 06:00 - 22:00). This allows programs to be used that are not available at home. To do this, you first need a VPN connection if you are not in the campus network:
- Instructions OpenVPN under Windows 10
- Instructions OpenVPN under GNU/Linux
- Instructions OpenVPN under MAC OS X
The remote access to the pool room computers can now be done either via the command line with ssh, or with the program x2go. You need your IMT username and password as well as the name of the host you want to access. And this can be e.g. one of the following:
Teaching computer (GNU/Linux): schroedinger
whiteboard computer (Win8): zener
Teaching computer (GNU/Linux): cer
whiteboard computer (Win8): xenia
