1. Notebook and Mobile Devices (Internet) Network Access at DESY Zeuthen

  • Two different classes of network access exist. One with access to the internal network and the other one is the guest network for visitors and guests.
  • All private notebooks at DESY Zeuthen are classified as untrusted and get no access to the internal network. The user can register his device for the guest network for one year. Please look at section 2.1 .
  • The DESY Computer Security Council (RSR) requires that a person who wants to attach a computer or other device in the internal DESY network signs responsible for the computer security of this device. After the confirmation of the user, who needs to be in possession of an account at DESY, the device will be classified as a trusted device. Please look at section 2.2 .

In the following you can find some more information about both network access classes, WLAN and also cable attached access.

The DESY-guest subnet is mainly provided for guests staying at DESY for a limited time. Gaining access to it only takes a few minutes. Access to internal services is limited (no Login into Windows Domain). The access rights basically correspond to those of anonymous external hosts, but some services like email, printing, AFS, ntp and web are available.

The MAC addresses of the device and the responsible person must be made known to the computer center.

The registration can be done

The URL is accessible from the internal network and can used by any user who has an account at DESY. 15 minutes after submitting the form, the registered device should be able to access the guest subnet. The expiration date of the registration is limited to one year, the default is one week.

2.2 Internal Access for Trusted Devices

Trusted Devices

The DESY Computer Security Council (RSR) issued a set of rules and recommendations to be followed by anyone operating computers attached to the DESY internal network.
By signing the form mentioned there, you acknowledge and accept these rules. A device is classified as trusted if the form signed by the responsible person has been filled with UCO Zeuthen.

For DESY notebooks centrally supported by DV Zeuthen, you only need to turn your attention to hints for using DESY Notebooks in Zeuthen (Windows) and sign a special form when the notebook is claimed from the computing after installation.

Cable Based Network Access

  • It is not yet possible to transfer cable MAC addresses of notebooks already registered at DESY Hamburg to Zeuthen.
  • The computing center in Zeuthen is not yet able to register your cable Mac address in DESY Hamburg. Please contact the corresponding network segment administrator in Hamburg if you need access to the cable based internal network in there.

Wireless Network Access

To use one of the internal wireless networks a registration (MAC address, user name, institute, email address) is necessary. You will receive the access parameter from UCO. The registration is valid in Hamburg and Zeuthen.

3. Availability of Network Facilities

  • Please make sure to include the complete socket number.
  • Disconnecting a PC from any other network wall socket and connecting your notebook instead will block the socket. Please don't do this.
