Posted: Wed Apr 25, 2012 6:48 pm Post subject: [SOLVED] wpa_supplicant can't initialize control interface

I have searched Google and these forums for answers but all answers I have found do not seem to address this type of issue.

Code:

# /etc/init.d/net.wlan0 start
* Bringing up interface wlan0
* Starting wpa_supplicant on wlan0 ...
mkdir[ctrl_interface]: No such file or directory
Failed to initialize control interface '"/var/run/wpa_supplicant/"'.
You may have another wpa_supplicant process already running or the file was
left by an unclean termination of wpa_supplicant in which case you will need
to manually remove this file before starting wpa_supplicant again.

* start-stop-daemon: failed to start `/usr/sbin/wpa_suplicant' [ !! ]
* ERROR: net.wlan0 failed to start

Interestingly, /var/run/wpa_supplicant does actually exist. When I remove it, I still get the same error. I have checked ps aux | grep wpa_supplicant but it does not show any such processes running (which is not surprising since it can't even get started). When I reemerged wpa_supplicant again, /var/run/wpa_supplicant was automagically created. Any assistance on this one would be appreciated as I have no clue anymore (I've used all sorts of distros for years, Debian, Ubuntu, even CentOS but this is the first system I have ever put together myself so I still consider myself a noob)...

dmesg:

Code:

/etc/conf.d/net:

Code:

# This blank configuration will automatically use DHCP for any net.*
# scripts in /etc/init.d. To create a more complete configuration,
# please review /usr/share/doc/openrc*/net.example* and save your configuration

## Configure Interface wlan0

/etc/wpa_supplicant/wpa_supplicant.conf:

Code:

ctrl_interface="/var/run/wpa_supplicant/"
ctrl_interface_group="wheel"

kewlness,

One thing I noticed that's incomplete in /etc/conf.d/net is the wpa_supplicant line. Change it to:

Code:

wpa_supplicant_wlan0="-Dwext -c/etc/wpa_supplicant/wpa_supplicant.conf"

Ah. Very correct and this has been changed.

However, even starting from the command-line (and with the above changes restarting net.wlan0) I get the same error.

Messing with /etc/conf.d/net there won't have fixed it, no. All you've done there is repeating the default values in the initscript.

wpa_supplicant runs as root, so it can't be a permissions problem on the directory. Try running this and see if it prints out any new errors:

Code:

wpa_supplicant -iwlan0 -c/etc/wpa_supplicant/wpa_supplicant.conf -d

Here the output (same error but you might see something I don't):

You may have another wpa_supplicant process already running or the file was
left by an unclean termination of wpa_supplicant in which case you will need
to manually remove this file before starting wpa_supplicant again.

Also, I thought it might be a permissions error as well, but I have not idea what they should be since these permissions make sense:

Code:

# ls -la /var/run | grep wpa
drwxr-xr-x 2 root root 4096 Apr 25 14:01 wpa_supplicant

kewlness,

My wpa_supplicant interface line is

Code:

ctrl_interface=/var/run/wpa_supplicant

yours is

Code:

ctrl_interface="/var/run/wpa_supplicant/"

Try dropping the quotes and '/' at the end.

Here's my entire file:

Code:

ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=wheel
update_config=1

network={
ssid="wireless"
psk="secret"
proto=RSN
key_mgmt=WPA-PSK
pairwise=TKIP
auth_alg=OPEN
priority=5
id_str="gentoo"
}

[/code]

Yep. That did it. Dropping the quotes around the ctrl_interface and the word "wheel" did the trick. Marking as solved.

Thanks!
