wpa_supplicant et WPA2

[De Leeuw Guy <G.De_Leeuw@eurofer.be>]

Bonjour,

Comment configurer wpa_supplicant pour le WPA2-PSK ?
Quand j'active l'option Authentification WPA2-PSK, je ne parviens plus à
me connecter
Voici mon wpa_supplicant.conf

update_config=1
ctrl_interface=/var/run/wpa_supplicant

network={
 ssid="ap-Eurofer"
 key_mgmt=WPA-PSK
#proto=WPA
 proto=WPA2
 pairwise=TKIP
 group=TKIP
 psk="*******************************"
}


Voici les erreurs
root@pcGDL:/home/guy# wpa_supplicant -Dwext -i wlan0 -c
/etc/wpa_supplicant.conf
