Interna

e-mail

Online-access at https://mail.intern.tuwien.ac.at.

Installation of an operating system

  1. Connect the computer with an ethernet cable to an active ip-socket.
  2. If the computer comes without a pre-installed operating system, it will usually try to boot over LAN and succeed.
  3. Alternatively, interrupt the booting process, get into the BIOS/EFI, enable and choose "Booting over LAN", "PXE-Booting" or similar.

  4. A choice of operating systems to be installed will be presented, courtesy of netboot.xyz.

The method described at point 3 can be used to boot into a live or rescue system.

Printers

Status of printers. The main printer is canon.

Installation of Printers

Linux:

De-install cups-daemon, make sure cups-client is installed.
Write the line

  • ServerName 128.130.169.2

into the configuration file, either the system wide /etc/cups/client.conf or .cups/client.conf in your home directory.
Create the configuration file if it does not exist.
This should work also for computers connected via WiFi.

Windows:

Use the dialog under Control Panel -> Devices and Printers -> Add a Printer. Insert the ip address, e.g., 128.130.169.13 for the canon printer. Install printer drivers for each printer.

Mac:

Choose Settings -> Printers and Scanners. If connected via ethernet, the canon printer is probably seen. If connected via WiFi, choose the Network tab, click on + to add a printer. Location: druck.fluid.tuwien.ac.at (or 128.130.169.2), Protocol: IPP printing, Queue: /printers/canon.

Backup

Follow a separate description to backup your data to our storage node b.fluid.tuwien.ac.at.

Network

Click here for a list of currently active ip- and telephone sockets. You need to give your credentials.

For a fresh install, configure a static ip-address. Werner Jandl will provide you with an ip-number and needs to know the hostname and MAC-address of your computer. Click here for the remaining parameters for a static configuration. Pay attention to our 25-bit subnet mask, 255.255.255.128, not the usual 24 bit, 255.255.255.0.

Note: A fresh install of an operating system usually tries to acquire an ip-address from a dhcp-server, which will succeed. However, these numbers are very limited and should be used only very temporarily.

Servers

A number of servers are accessible for all members of the institute with their upTUdate credentials. Connect via ssh, to s15 connection by webdav (https://s15.fluid.tuwien.ac.at) with your browser is also possible. On s15, E322 is the public folder, and it is the root folder when accessed via dav.

machine

short description

b

CPU Intel Xeon E3-1230 v5, 3.4 GHz, 4 cores, 70 TB hard disk storage, 32 GB RAM

gs1

CPU Intel Xeon E5-1620 v3, 3.5 GHz, 4 cores, GPU GeForce GTX 960, 32 GB RAM, 2 TB storage

s15

CPU 2 x Intel Xeon E5-2680 v3, 2.5 GHz, each 12 cores, 384 GB RAM

wombat

CPU Intel i7 980, 3.33 GHz, 25 GB RAM

The service tag of s15 is 1X1ZF82, which may be used to find details of the hardware.

The storage node, b.fluid.tuwien.ac.at is housed in room BA U1 G18, other machines in BC U2 A18.

The configuration for authentication by querying the TU ldap-server is described here, in german.

Applications

On s15, users can use mathematica, matlab and the NAG-library. Also, under /home/E322/Software, installation files can be copied to install software on one's personal computer.

To use the NAG-libarary, copy the compilation-command from the appropriate script in /usr/local/share/NAG/cll6i26dcl/scripts, or copy the entire script to your working directory. These scripts link with the stand-alone static NAG-library, with the split up NAG-libraries and with shared versions of both.
For instance, to query NAG library implementation details and the status of the license, do 

cp /usr/local/share/NAG/cll6i26dcl/scripts/nagc_example_shar_mkl .
./nagc_example_shar_mkl a00adc

Library

To borrow or return books from the faculty library, the computer in our conference room, BA 07 G12, can be used. The computer is located at the rear wall next to the windows.

Requirements:

  1. TU card or TU library card

  2. books to loan or return, with the barcode from the library inside the front cover

Procedure:

  1. switch on computer and screen, if necessary
  2. click user E322
  3. click on the ALEPH icon on the desktop, login with user TUW322, password tuw322
  4. click the head symbol and register with your TU card or TU library card, using the barcode reader

  5. to borrow: click "|->" symbol (Ausleihe) and read the barcode inside the front cover of individual books
    to return, click on the corresponding button in the list of borrowed books

  6. quit ALEPH, log out, switch off computer and screen

Mathematica and Matlab

Matlab and Mathematica are installed on s15.fluid.tuwien.ac.at. Mathematica and Matlab both query a license server. Therefore, these programs can also be installed on your desktop computer, see further below. Fairly recent installation files are usually located under s15.fluid.tuwien.ac.at/home/E322/Software

To use the license server for Mathematica, create the file mathpass in the directory Configuration/Licensing of your mathematica installation and write the line !mathematica.it.tuwien.ac.at into it.

The license server for Matlab is given in a file called network.lic, usually to be found in /usr/local/share/MATLAB/R20XX/licenses/network.lic. This file contains the lines 

SERVER matlab.it.tuwien.ac.at 005056bf2e9e 1751
USE_SERVER

Installation of Matlab

To install matlab on a personal computer, mount the directory on s15 containing the most recent matlab-version, and run the installer with informations given in the file installer_input.txt. This will install a choice of toolboxes to /usr/local/share/matlab/R20XXx. The resulting matlab installation amounts to a bit less than 10 GB. Alternatively, copy the file /home/E322/Software/Matlab/Linux/v*/installer_input.txt to your computer and edit it to your choice. Another alternative is to run the installer interactively, without the -inputFile option.
