View source for Eduroam configuration in /Linux/BSD: wpa supplicant

= Unix/Linux/BSD: wpa_supplicant =

It is important that you have in place the latest version of firmware and driver for your wireless card and that your firmware supports TKIP encryption or better. Some drivers also has a problem with connecting to access points that does not broadcast it's SSID. Be sure to apply any available patches.

[http://hostap.epitest.fi/wpa_supplicant/ wpa_supplicant can be downloaded here.]

Be sure to read the README file as it explains about the support in various drivers.

Before the wpa_supplicant can be compiled, you must have 'yes' on the following options in the ''.config'' file:

CONFIG_IEEE8021X_EAPOL=y
CONFIG_EAP_MSCHAPV2=y
CONFIG_EAP_TLS=y
CONFIG_EAP_PEAP=y
CONFIG_EAP_TTLS=y

It is strictly only necessary to have TLS, PEAP or TTLS (depending on what your institution uses) but the others might prove useful to have at a later time. For TLS you also need a user's certificate.

You also need to define what driver you are using. For example the MAD WiFi driver:

CONFIG_DRIVER_MADWIFI=y

Then there is

''make''

before you install with

''cp wpa_cli wpa_supplicant /usr/local/bin''

...or somewhere else you prefer.

With your favorite editor edit

''/etc/wpa_supplicant.conf''

so that it contains the following (using TTLS):

<pre>
ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=root

network={
ssid="eduroam"
scan_ssid=1
key_mgmt=WPA-EAP
eap=TTLS
identity="brukernavn@student.uib.no"
password="password"
phase1="peaplabel=0"
phase2="auth=MSCHAPV2"
}

ctrl_interface=/var/run/wpa_supplicant

Modify user name, password and certificate name to what is applicable at your institution.

Start wpa_supplicant like this:
''wpa_supplicant -D madwifi -c /etc/wpa_supplicant.conf -d -i ath0''
</pre>

''iwconfig'' should then be able to give you an output like this:

<pre>ath0 IEEE 802.11b ESSID:"eduroam" Nickname:"mycomputer.uib.no"

Run ''dhclient ath0'' to receive an IP address from the DHCP server.
