eduroam with Linux / Ubuntu 14.04 LTS

Setting up the eduroam WLAN with the CAT tool

After downloading the eduroam CAT you have to make it executable. To achieve this first right click on the file and select Properties then select the Permissions tab and check the box next to Execute . Alternatively the file can be made executable by running chmod +x on that file. Now you can run the assistant by double clicking it and selecting Run. Now walk through the assistant until you are asked for your userid, then enter your username as described in the username section of this article. After clicking on OK enter your password and confirm it.

After finishing the assistant, the Network Manager should automatically connect you to the eduroam network if it is available.

If you do not have a Network Manager running during the installation, the assistant will create a wpa_supplicant.conf. For details on how to use this config file see the article wpa_supplicant.

Gnome Network-Manager

If the eduoram network is configured manually a “man-in-the-middle attack” is possible because the client will accept any certificate signed by the Deutsche Telekom CA. So if it is possible the configuration assistant should be used.

Manual setup of the eduroam WLAN

The Gnome Network-Manager can be used to set up the connection with eduroam (tested under Ubuntu 14.04 LTS).

Select “eduroam” from the list of available WLAN SSIDs. When connecting the Network Manager prompts for the connection details (s. picture). The suggested settings are generally good, provide the following information:

You can find the CA certificate under /usr/share/ca-certificates/mozilla/Deutsche_Telekom_Root_CA_2.crt . Enter the username according to the table in the username section and the corresponding password.
