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.
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.
