Failed to connect to wpa_supplicant

Lufbery · 01-06-2008, 04:41 PM

Hi all,

I'm getting this message...

Code:

Failed to connect to wpa_supplicant - wpa_ctrl_open: No such file or directory

...when I try to use wpa_supplicant. It's looking for /var/run/wpa_supplicant as specified in the /etc/wpa_supplicant.conf.

/var/run/wpa_supplicant really doesn't exist.

I'm using the wpa_supplicant package from Eric's (Alien Bob) site.

I've got other questions on getting wireless to work, but this is my first.

Why am I getting that error, and how do I fix it?

Thanks,

-Drew

Hi all,

A few more quick notes. I installed the Madwifi package from Alien Bob's site before trying to get WPA_supplicant working.

I've got a WEP-encrypted network.

To help things out a bit, here's what I added to my rc.inet1.conf:

Code:

# Added by Drew #
# Config information for ath0 (usng dhcp):
IFNAME[1]="ath0"
IPADDR[1]=""
NETMASK[1]=""
USE_DHCP[1]="yes"
DHCP_HOSTNAME[1]=""
WLAN_WPA[1]="wpa_supplicant"
WLAN_WPADRIVER[1]="wext"

And here's what I added to the rc.wireless.conf

Code:

00:15:E9:72:F2:92)
	INFO="D-LINK WNA-2330"
	ESSID="any"
	;;

Hopefully this will help debug the problem.

Hi all,

Here's something else that may help. This is the output from ifconfig:

Add the following line to your /etc/rc.d/rc.inet1.conf WLAN_WPACONF[1]="/etc/wpa_supplicant.conf"
right after
WLAN_WPADRIVER[1]="wext"

Alien Bob · 01-07-2008, 02:41 AM

You should post your /etc/wpa_supplicant.conf file (and edit out the private key) so that we can check if that file is at all correct.

Eric

Road_map · 01-07-2008, 09:13 AM

Add the next line in /etc/wpa_supplicant.conf file:

Code:

WPAOPTS="-Dwext -iath0 -c/etc/wpa_supplicant.conf"

P.S. In /etc/rc.d/rc.inet1.conf file. Sorry.

Okay, I did that, and made a few changes to my wpa_supplicant.conf.

Here's that file:

Code:

# See /usr/doc/wpa_supplicant-0.5.8/wpa_supplicant.conf.sample
# for many more options that you can use in this file.

# This line enables the use of wpa_cli which is used by rc.wireless
# if possible (to check for successful association)
ctrl_interface=/var/run/wpa_supplicant
# By default, only root (group 0) may use wpa_cli
ctrl_interface_group=wheel
eapol_version=1
ap_scan=1
fast_reauth=1

# WEP protected network:
network={
  scan_ssid=0
  ssid="Home Network"
  key_mgmt=NONE
  wep_key0="EDITED"
  priority=5
  auth_alg=SHARED
}

# Plaintext connection (no WPA, no IEEE 802.1X),
# nice for hotel/airport types of WiFi network.
# You'll need a recent version of wireless-tools for this!
network={
  ssid="any"
  key_mgmt=NONE
  priority=2
}

So...now I don't get the original error message, but [pre]wpa_cli status[/pre] says the status is "scanning," and I'm not able to connect.

Any suggestions?

Thanks,

-Drew

Lufbery · 01-07-2008, 06:44 PM

Hi all,

I may have found my (latest) problem: I had the wrong ssid in my wpa_supplicant.conf file.

I've made that change and I'll see if that fixes things, of if there's more I need to do.

EDIT: That only seemed to work halfway. I went through wpa_gui and it said I was connected, but:

(1) I couldn't connect to the Internet or open an SSL connection to my desktop computer, and

(2) I can only seem to connect as root. I can't even use wpa_cli or wpa_gui as an unpriviledged user -- even though I have my user in the wheel group.

I'm closer, but I still need help.

Thanks,

-Drew

Lufbery · 01-08-2008, 06:44 AM

Hi all,

I'm at the point now where the wpa_gui status vacillates between "scanning" and "associating."

Any suggestions?

Regards,

-Drew

bioe007 · 01-08-2008, 10:17 AM

I would skip the gui configuration for now.

go to a CLI and run

wpa_supplicant -dwu -Dwext -iath0 -c /etc/wpa_supplicant.conf

to see what wpa_supplicant is really doing. if it seems OK (no config parse errors) try dhcpcd -d ath0 in another terminal.

you can also try changing

ap_scan=1

to

ap_scan=2

this is helpful for ndiswrapper - I dunno if it applies to madwifi. Also wpa_supplicant offers a driver 'madwifi' (substitute for wext ?)

finally, I wonder if your key was generated correctly? did you use wpa_passphrase to make it?

Lufbery · 01-08-2008, 11:36 AM

No, the key is text, and that's how I have it set up on the router. I'll look into other options, but this worked before with OpenSUSE 10.2 and knetworkmanager.

I'll try your other suggestions and see what happens.

Regards,

-Drew

Lufbery · 01-11-2008, 01:20 PM

Hi all,

Here's an update. Initially I got everything connected, but wasn't getting an IP address from the router. Digging a little deeper, I figured out that the best (or at least easiest) way for me to address this problem was to assign a static IP address to my laptop using the router settings.

That's what I did, and everything is working perfectly now.

Most of the work I did was in my rc.inet1.conf file I'll post it and my wpa_supplicant.conf file this weekend; just in case other people want to see how I configured things.

Thanks for your help, everyone.

# Theory of operation :
#
# The script attempts to match a block of settings to the specific wireless
# card inserted, the *first* block matching the card is used.
# The address format is "hwaddr", with * as a wildcard.
# 'hwaddr' is the unique MAC address identifier of the wireless card.
# The MAC address is usually printed on the card, or can be found via ifconfig.
# Some examples here use only half of the MAC address with a wildcard to
# match a whole family of cards...
#
# All the Wireless specific configuration is done through the Wireless
# Extensions, so we will just call 'iwconfig' with the right parameters
# defined below.
# Of course, you need to have iwconfig installled on your system.
# To download iwconfig, or for more info on Wireless Extensions :
#       http://www.hpl.hp.com/personal/Jean_Tourrilhes/Linux/Tools.html

# Note : you don't need to fill all parameters, leave them blank, in most
# cases the driver will initialise itself with sane defaults values or
# automatically figure out the value... And no drivers do support all
# possible settings...

I had a similiar problem. I what I did was only use the inet1.conf file for the device and IP address. Then i entered the wpa information in the wireless.conf. Move your information in wireless.conf above the generic settings because it reads top to bottom(atleast for me it did). in wireless.conf essid, wpa, and wpadriver is all i used. this did the trick for me. hope this helps.
