Internet and network access within the institute

It is mandatory that all computers and other devices that are to be connected to the Internet via network socket must be configurable via DHCP. Internet and network access is provided exclusively by the IT department and ZDV. The use of a network socket must be requested. In particular, the MAC addresses of devices that are to be newly connected via a network socket must have been registered beforehand. Here, the IT takes care of the configuration and registration.

Information on using our ticket system

Due to the current situation, most of our IT group is located in the home office. If you have a request or a question, please use our ticket system. We ask you not to recycle an old ticket, because this way the ticket is not recognized as a new but as an old ticket and will appear at the bottom of our system and might be overlooked. You can also leave out the "thank you" mail after we solved the problem, because this will open the ticket again and we have to close it a second time.

Call phone numbers with Skype for Business Mobile

Using the app

To make calls to a phone number from the Skype for Business App, all you have to do is click on the dialpad icon in the upper right corner.

Then you can dial the number.

This guide works for both IPhone and Android devices.

You can find more information on the ZDV website (German).

Create ssh-tunnel to kph infrastructure

Manual on how to create a ssh-tunnel to kph infrastructure.

For this you will need an KPH-Account and access via SSH has to be activated by us.

If you already have an KPH-Account, write an E-Mail with your KPH username to and ask to be enabled for SSH. Please attach your public SSH-key to the E-Mail.

After we enabled your account, you can create a ssh-tunnel with Linux (batch, etc.) or Windows 10 (cmd, etc.) as follows:

ssh -N -L <local-port>:<kph-pcname>:<kph-port>

  • <kph-pcname>  = Name of your computer in the institute. e.g.
  • <kph-port> =  Port number of your computer within the KPH. e.g. RDP 3389
  • <local-port> = any port number > 1000. You access this locally. e.g. 12345

Now you can establish a connection on your local computer to the KPH computer using the <local-port>. e.g. by putting localhost:12345 as RDP-Client destination.

Simply terminate the tunnel at the end of the session.

Older versions of windows:

Alternatively for older versions of windows your can use the program PuTTY. Please follow the instructions for Generating a SSH key with PuTTY.
