Configurer wpa_supplicant et madwifi

Featured Replies

Posté(e)

Salut à tous! :transpi:

J'a récement installé Linux fedora core 5 sur mon pc. Mais je rencontre quelques problèmes pour configurer le wifi avec une ip fixe et le cryptage wpa-psk.

Ma carte wifi est une D-link Dwk-g520 avec un dongle atheros AR5212.

J'ai donc mis à jour le depot livna et lancé yum install madwifi. Jusque là tout se passe bien. Quand je tape la commande iwconfig j'obtient:

ath0 IEEE 802.11g ESSID:""

Mode:Managed Channel:0 Access Point: Not-Associated

Bit Rate:0 kb/s Tx-Power:18 dBm Sensitivity=0/3

Retry:off RTS thr:off Fragment thr:off

Encryption key:off

Power Management:off

Link Quality=0/94 Signal level=-95 dBm Noise level=-95 dBm

Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0

Tx excessive retries:0 Invalid misc:0 Missed beacon:0

Je lance les commandes pour paramétrer l'ip l'ssid la passerelle etc... :

ifconfig ath0 192.168.0.2 netmask 255.255.255.0

route add default gw 192.168.0.1 ath0

iwconfig ath0 essid neho

iwconfig ath0 channel 6

j'ai donc tenté de configurer wpa_supplicant j'y ait donc rentré lesinfos suivantes:

ctrl_interface=/var/run/wpa_supplicant

network={

ssid="NEHO"

scan_ssid=1

proto=WPA

key_mgmt=WPA-PSK

psk="ma clé"

}

Je tente d'initialiser avec la commande:

wpa_supplicant -i ath0 -D madwifi -c /etc/wpa_supplicant/wpa_supplicant.conf

mais la le pc me retourne:

ICE default IO error handler doing an exit(), pid = 2804, errno = 0

Trying to associate with 00:11:95:2e:22:30 (SSID='NEHO' freq=2437 MHz)

ioctl[iEEE80211_IOCTL_SETMLME]: Invalid argument

Association request to the driver failed

Associated with 00:11:95:2e:22:30

WPA: Key negotiation completed with 00:11:95:2e:22:30 [PTK=TKIP GTK=TKIP]

CTRL-EVENT-CONNECTED - Connection to 00:11:95:2e:22:30 completed (auth)

Impossible de trouver d'ou vient le problème...

De plus quand je reboot le pc, les paramètres rentrés avec les commandes suivantes sont perdus:

ifconfig ath0 192.168.0.2 netmask 255.255.255.0

route add default gw 192.168.0.1 ath0

iwconfig ath0 essid neho

iwconfig ath0 channel 6

Si quelqu'un pouvait m'aider!

Merci

En gros tous les fichiers pour résumer(theoriquement je n'ai pas de commande à taper pour que tout se lance au demarrage du pc?):

-iwconfig donne tout de suite apres le demarrage:

-test de la commande wpa_supplicant -iath0 -Dmadwifi -c/etc/wpa_supplicant.conf qui ne change rien:
