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”. Please also note that the behavior when executing files has been set correctly under “Files Preferences”.
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.
Manual setup of the eduroam WLAN
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.
To setup the connection with eduroam click on “System Settings / All Settings / Network” (tested under Ubuntu 14.04 LTS). Select “Wireless” → “eduroam” (1.) from the list of available WLAN SSIDs. Then click on the wifi icon in the upper right corner (2.) to open the network menue. Now select “Edit connections…” (3.). Select Wi-Fi “eduroam” and click on “Edit…” to edit the eduroam settings.
You can find the CA certificate under /usr/share/ca-certificates/mozilla/T-TeleSec_GlobalRoot_Class_2.crt . Enter the username according to the table in the username section and the corresponding password.
