For a proper day-to-day operation we are running various tools which are, depending on their possibilities, available to public users, segment administrators or the network operating center only.

List of public available tools

  • Port Database to check network wall plugs
  • MAC Adress Database to check registered MAC adresses (essential for the use of the DESY Intranet)
  • A list of segmentadmins shows which person is reponsible for which subnet and gives detailed information about the subnets (repsonsible persons, Adress Range, Subnet Mask, Gateway)


List of available tools for segment administrators

  • The IP-Management System (QIP) offering the possibilities for giving IP-Adresses, configure DHCP settings, register MAC addresses, etc. There will be used DHCP-Option-Templates for DHCP settings. Only a few are usable for Segmentadministrators. A List of Templates and Information will be found in the following PDF.
  • QIP Command Line Interface - QIP-CLI

Instead of QIP Web-Client an CLI on Linux-Server is available.
For using CLI you have to logon with an AFS-Account on  or via RDP (or other X-Application)
Please make use of one of the Environmentvariablen:
sh-User (ksh, zsh, etc.) it must be '. /opt/qip/current/etc/shrc' csh-User (csh, tcsh) it must be 'source /opt/qip/current/etc/cshrc'
Or put it in your Loginscript. Then You can use all CLI commands.

To hide Your PW if You are using CLI, use the following Script, which create the files qip.pcy and qip.key in Your ~/private Directory. It’s recommended!

Starting the Script and type Your actual DESY-Standard Password.
   [peanut-el7] # setup-qip
The Script will create the qip.key and qip.pcy in Your private Directory  ~/private. If You have to change Your DESY-Default PW, You have to run this Script once more.
You can check if QIP-CLI is running correctly, type
[twitt@peanut-el7]~% qip-getorganization 
If DESY appears, QIP-CLI is working properly.
Keep in Mind, if You have to change Yout DESY-Default Password, You have to run the Script again.
