wpa_supplicant: ioctl[SIOCSIWAUTH]: Operation not supported

alkos333 · 08-30-2007, 01:36 AM

It used to run fine on Slackware 11.0 with ipw3945. I upgraded to 12.0 and use iwl3945 now, which uses wlan0 instead of eth1.

Although it seems to work, I'm getting the following message on the start up:

Code:

root@alkos333_TPT60:/var/run# !wpa_supplicant
wpa_supplicant -B -i wlan0 -D wext -c /etc/wpa_supplicant.conf 
ioctl[SIOCSIWAUTH]: Operation not supported
WEXT auth param 4 value 0x0 - ioctl[SIOCSIWAUTH]: Operation not supported

Here is a little bit more info from the commands I ran:

Code:

root@alkos333_TPT60:/var/run# lsof /var/run/wpa_supplicant/wlan0 
COMMAND    PID USER   FD   TYPE     DEVICE SIZE  NODE NAME
wpa_suppl 8087 root    6u  unix 0xef787040      39613 /var/run/wpa_supplicant/wlan0

Code:

root@alkos333_TPT60:/var/run# grep IEEE80211 /usr/src/linux-$(uname -r)/.config
CONFIG_IEEE80211=m
# CONFIG_IEEE80211_DEBUG is not set
CONFIG_IEEE80211_CRYPT_WEP=m
CONFIG_IEEE80211_CRYPT_CCMP=m
CONFIG_IEEE80211_CRYPT_TKIP=m
# CONFIG_IEEE80211_SOFTMAC is not set

if i remember correctly, your command should be
wpa_supplicant -B -iwlan0 -Dwext -c/etc/wpa_supplicant.conf
(no spaces after -i -D -c)
try it. Maybe the problem will disappear.

No, that doesn't make any difference because wpa_supplicant seems to be running and I'm actually connected to a WPA AP right now. I'm just trying to figure out how to get rid of that error/warning.

IIRC you can get more verbose output from wpa_supplicant by adding -dd or -ddd to the command. Maybe this brings some more information up.

Use the ticket 462 of madwifi to update your madwifi driver so that it can adhere to WE-18 standard

But I'm not using a madwifi driver though, I'm using iwl3945?

The error usually occurs when the driver does not support a particular IOCTL. Just downloaded ipw3945 version 1.2.2 and verified that the SIGCSIWAUTH is supported by this driver. Download this driver and compile it with WIRELESS_EXT flag set to 18 and it should work.

I don't like ipw3945 because it requires a regulatory daemon and just isn't as stable as iwl3945. I have already reported this to iwl3945, so hopefully it will be fixed soon.
