ZDV Linux

We provide modified Linux versions. On these versions you may use your university account to log in and work directly on your home folder at the Data Center ('ZDV'). This way, all data gets saved on a Data Center server and you can access it from any computer.
The Data Center administrates these installations remotely and supplies them with automatic updates.


Automated Linux Installation

The Data Center provides an automated network Linux installation. With this installation, you may log in with your university account and access to your home and group folder will already be set up.
This installation is maintained remotely by the Data Center via cfengine.

The following distributions are available at the moment:

  • Debian 8 Jessie
  • Debian 9 Stretch

Requirements

  • To run an automated installation, your computer needs an IP address inside the university network. If your computer doesn't have one, you may request an IP here (German only). Please enter pxelinux at "Anmerkung".
  • If the computer already has an IP address, pxelinux must must have a DNS entry. Please ask your network administrator for your workgroup.
    If this option doesn't exist, your network administrator may request an activation of this option from the Data Centers's networkgroup.
  • If Windows was installed before on this host, any existing AD objects need to be deleted beforehand.
    You can request this from your OU-Admin.
  • To boot your computer via network you need to enable networkboot or PXE boot in your BIOS.

⚠ Attention: It's recommended not to dual boot Windows and Linux. We recommend to install the operating system you use the most, other systems may be installed inside a virtual machine.
