			This is Carleton's repository for all things Raspberry Pi.

			=== Using Raspberry Pi on Eduroam ===
			In order to use a raspberry pi board on the eduroam network, you will need to provide a valid set of credentials. If you are using a graphical interface on the pi, this is relatively trivial, but from the terminal, it is less obvious.

			==== Terminal configuration ====
			From the linux terminal, edit the file '/etc/wpa_supplicant/wpa_supplicant.conf' so that it matches the following format:
			<code>ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
			update_config=1

			network={
			ssid="eduroam"
			priority=1
			proto=RSN
			key_mgmt=WPA-EAP
			pairwise=CCMP
			auth_alg=OPEN
			eap=PEAP
			identity="USERNAME@carleton.edu"
			password=hash:HASHED_PASSWORD
			phase1="peaplabel=0"
			phase2="auth=MSCHAPV2"
			}</code>
			In this case, USERNAME is your Carleton username, and HASHED_PASSWORD is obtained by running the command
			<code>echo -n 'password_in_plaintext' \| iconv -t utf16le \| openssl md4 > hash.txt</code>
			While possible to use a plaintext password in this file it is strongly not advised.

			Once you have made these modifications, reboot the machine. You should now have functional wifi.

			If not, depending on the version of operating system you are using, you may need to make the following additional modifications. These are required because the existing Wifi chip driver doesn't play nicely with getting a DHCP address from an enterprise WPA-EAP access point.

			Edit the file "/lib/dhcpcd/dhcpcd-hooks/10-wpa_supplicant". Look for 'nl80211'. Change that line to:
			<code>wpa_supplicant_driver="${wpa_supplicant_driver:-wext}"</code>
