Configuration guide eduroam


As with any other operating system, it is of great importance to complete the configuration / installation of the root certificate and set it up for use with 802.1x-Wi-Fi connections, before the first connection to the eduroam WLAN is made.

Representing the many Linux distributions available on the market, we present here an configuration for eduroam with Ubuntu 14.10.

Wi-Fi configuration with GNU/Linux

In order to connect to the eduroam Wi-Fi with GNU / Linux, we recommend the configuration via the Network Manager. This provides all necessary configurations via a graphic interface.

First, it is necessary to install the root certificate "T-TeleSec_GlobalRoot_Class_2". This can be downloaded as "T-TeleSec_GlobalRoot_Class_2.crt" from the the DFN website.

After the certificate is successfully installed, click on the Wi-Fi icon in the menu bar and select the SSID "eduroam". Then enter the settings from the following screenshot:

  • Security: WPA & WPA2 Enterprise
  • Authentication: Protected WAP (PEAP)
  • CA certificate: T-TeleSec_GlobalRoot_Class_2.crt
  • Inner authentication: MSCHAPv2
  • Username: <ZDV login ID>@uni-tuebingen.de
  • Password: Password of ZDV login ID


  • Even for students the username ends on "@uni-tuebingen.de".
  • You can find further information on the Wi-Fi page.

In addition to the Network Manager, it is also possible to manually write these settings to the corresponding configuration file (wpa_supplicant). However, this is only recommended for more experienced users. The values can be adopted as shown above.
