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

Printers

Status of printers

When a new Linux system is installed, usually the cups-daemon is started. The cups-daemon finds the printer server without further intervention. Alternatively, only the cups-client needs to be installed, the cups-daemon can be de-installed. In this case, the line

is necessary, in one of the files /etc/cups/client.conf or .cups/client.conf in your home directory. Create the file, if needed.

Network

Click here for a list of currently active ip- and telephone sockets.

For a fresh install, configure a static ip-address. Iris Mansky will have to provide you with an ip-number and should know the hostname and MAC-address of your computer. For a static configuration, have a look at this example.

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.

Webserver

s15.fluid.tuwien.ac.at, files.fluid.tuwien.ac.at, wombat.fluid.tuwien.ac.at

The two machines s15 and wombat are the computing workhorses of the institute. Both computers can be reached by ssh by all those members of the institute which are listed in the tiss-database. The server s15 has the alias files.fluid.tuwien.ac.at and can also be reached via http or webdav, i.e., files.fluid.tuwien.ac.at can be accessed with a web-browser or mounted using the webdav-protocol, see further below.

The credentials to log in to both machines are are the same as for your e-mail. Check at https://mail.intern.tuwien.ac.at. When authenticating with your TU-credentials, all members of the institute are member of the group E322, group id 2153 and have, by default, read-access to all files and folders of other members of E322. If files should be kept confidential, it is therefore necessary to remove the read-permission for the group from files or folders.

S15 is equipped with two CPUs, Intel E5-2680v3 and has 384 GB RAM. The Service Tag is 1X1ZF82, which may be used to find details of the hardware.
Wombat has an even faster CPU, Intel i7 980 @ 3.33 MHz and 25 GB RAM. Wombat will hibernate if idle for more than four hours. To wake up wombat, login to s15 and issue the command wakeonlan wombat.

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//cll6i25dcl/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.

Webdav

To mount a file system with webdav, under Windows open the file explorer, right click on "Networks", chose "Map Network Drives" and type https://s15.fluid.tuwien.ac.at. Then, give your credentials. With nautilus (e.g., under ubuntu) choose "Connect to server" and type davs://s15.fluid.tuwien.ac.at. For kde the line is webdav://s15.fluid.tuwien.ac.at.

On s15, a users home-directory is created automatically on the first login via ssh, but not when accessing by the web interface or via webdav. Therefore, to create a personal space on s15, you must log in at least once via ssh.

To provide for malfunction of the authentication service, it is probably wise to generate a public/private key-pair with ssh-keygen on your personal computer and append your thusly created public key, .ssh/id_rsa.pub, to .ssh/authorized_keys in your home directory on the remote computer, e.g., s15.

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

e-mail

Online-access to your e-mails is available at https://mail.intern.tuwien.ac.at.    H. Steinrück.

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.
