I want to connect my Debian Squeeze machine to my school wireless network with wpa_supplicant.

I think the network uses 802.1X authentication, because when the other students connects to the network for the first time in Windows they enter their username and password then the connection is established. I have asked the the IT staff but they do not known what 802.1X, PEAP EAP etc. is and just say "Enter the login details in the box!".

If I bring a Windows 7 machine to school and successful connects to the network, is it then possible for me to extract the information [and extract a certificate if used on the network] from Windows somehow so i can setup the wpa_supplicant.conf correctly on Debian?

The information I want to extract is which protocols are used, like PEAP,MSCHAP etc.

This question came from our site for system and network administrators.

Sorry, but you're going to have to find someone in your School's Network Administration that knows what they're talking about to at least give you the general details of how to connect. – Chris S Aug 17 '11 at 16:43
Does your school list instructions for setup online anywhere often the setting to set up Mac OSX show the actual settings – Lamar B Aug 17 '11 at 22:19

Maybe sudo iwlist scan wlan0 gives you some usable hints. Be sure to use sudo or su -c or you will only get data from an old scan.

Here you can see that this AP uses WPA2 TKIP for authentication.
