Eduroam Linux Setup
The preferred way of setting up the eduroam SSID on any operating system is the Xpress Connect Configuration Utility that can be found at oit.siu.edu/wireless/xpc. The utility sets up the SSID automatically with little input from you.
This document assumes the Gnome desktop shipped with many common Linux distributions. To join eduroam with the Gnome windowing system you must configure the NetworkManager with an eduroam profile. When asked for your credentials provide credentials based on the following. If you are from <your institution>.edu (e.g. siu.edu, illinois.edu, uark.edu) and your username (sometimes called NetID) is XXXXXXX then your login name is XXXXXXX@<your institution>.edu. Your password is your normal password at your home institution.
Creating an eduroam Profile
Open the NetworkManager as seen below, select the Wireless tab and click "Add".
In the dialog that appears change the "Connection Name" to eduroam. You may opt to check the "Connect automatically" check box. Then fill the Wireless configuration tab as seen in the image below. The SSID should be "eduroam" (without quotes) and the Mode should be set to "Infrastructure". Next select the "Wireless Security" tab.
In the Wireless Security tab there are many settings to configure. In the "Security" drop-down box select "WPA & WPA2 Enterprise". In the Authentication drop-down menu select the PEAP or TTLS authentication method, whichever is used by your home institution. Unless your home institution provides a CA certificate leave that drop-down empty. If they do provide a certificate select it by clicking the file icon on the right side of the widget. If you are using PEAP leave the "PEAP version" drop-down set to "Automatic". TTLS users have no analogous setting. In the "Inner authentication" drop-down select the appropriate option for your home institution (MSCHAPv2). Finally provide your username (eg email@example.com) and password from your home institution. See below for completed forms. Once the forms look correct (something like those below) press "Apply".
Finally, if you have not selected a CA Certificate in the previous step you will be warned (as seen below). Simply select "Don't warn me again" and press "Ignore" unless you have a certificate, at which point please select it.
After these settings are configured, you should be able to connect by pressing "Connect" in the following dialog. In the future you may connect via the NetworkManager icon in the task-bar.
