wpa_supplicant socket error

[Fabio Sangiovanni]

Hi, I'm trying to get wpa_supplicant working on my Slackware 10.2.
The NIC is an Atheros based wireless card, so I'm using madwifi 
(perfectly compiled and loaded as modules on startup).

I've tried both compiling wpa_supplicant from source code and installing 
a binary tgz package, but with no success.

When I run wpa_supplicant -iath0 -Dmadwifi -c/etc/wpa_supplicant.conf 
-dd, I get:

I think the problem is in the line:

socket(PF_PACKET): Address family not supported by protocol

There seems to be a kernel-related issue that I couldn't be able to fix.
Unfortunately, searching Google hasn't been useful.


My wpa_supplicant.conf file is as follow:

ctrl_interface=/var/run/wpa_supplicant
#ctrl_interface_group=0
ap_scan=1

network={
   
   ssid="sanjioh"
   scan_ssid=1
   mode=0
   proto=WPA
   key_mgmt=WPA-PSK
   auth_alg=OPEN
   pairwise=TKIP
   group=TKIP
   psk="xxxxxxxxx"
}


Kernel  2.6.16.20.

Thanks a lot for helping me.
