wpa_supplicant y clave wep

Sab Nov 5 03:47:01 CST 2005

Bones.

Como necesito alguna forma automática de suministrar claves wep a los AP con 
los que trabajo (aunque pueda hacerlo a mano), me he puesto a trastear con 
wpa_supplicant, aunque tengo problemillas.

La clave es la correcta,  ya que configurando manualmente va todo ok.  Tengo 
un portátil con una ipw2200bg, y uso breezy, kernel 2.6.14 compilado por mi, 
y los últimos drivers del proyecto ipw (v.1.0.8, ieee80211 v.1.1.6 y firmware 
2.4).

La configuración del demonio es "-B -w -i eth1 -D ipw 
-c /etc/wpa_supplicant.conf", y mi fichero de configuración es como sigue (a 
excepción de la clave wep, 26 dígitos decimales):
-----
ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=0
eapol_version=1
ap_scan=1
fast_reauth=1
network={
  ssid="QAP"
  key_mgmt=NONE
  wep_key0=00000000000000000000000000
  wep_key1=
  wep_key2=
  wep_key3=
  wep_tx_keyidx=0
#  auth_alg=SHARED
  auth_alg=OPEN
}

network={
  ssid="any"
  key_mgmt=NONE
}
-----

Por último (largo!), los mensajes que da al arrancar en consola.  Nunca llega 
a suministrar la clave wep a la eth1 (comprobado con iwconfig eth1 en otra 
consola).  Gracias anticipadas por cualquier respuesta  ;)
