startup script for wpasupplicant

cccc · 03-05-2006, 06:24 PM

hi

I have opensuse 10.0 and wlan running with WPA encryption.
if I start the wpasupplicant from CLI:

Code:

# /usr/local/sbin/wpa_supplicant -w -i ath0 -D madwifi -c /etc/wpa_supplicant.conf -dd
State: GROUP_HANDSHAKE -> COMPLETED

evrything is fine.

but I'd like to start it automatically, using this script:

Code:

#!/bin/sh

PATH=/sbin:/bin:/usr/sbin:/usr/bin

DAEMON=/usr/local/sbin/wpa_supplicant
PIDFILE="/var/run/wpasupplicant.pid"
CONFIG="/etc/wpa_supplicant.conf"
PNAME="wpa_supplicant"

# insane defaults
OPTIONS="-Bw" # daemonize and wait for interface
ENABLED=0

[ -f /etc/default/wpasupplicant ] && . /etc/default/wpasupplicant

if [ "$ENABLED" = "0" ]; then
	echo "wpasupplicant: disabled, see /etc/default/wpasupplicant"
	exit 0;
fi

[ -f $CONFIG ] || ( echo "No configuration file found, not starting."; \
	exit 1; )

[ -f $DAEMON ] || exit 0

set -e

case "$1" in
	start)
		echo -n "Starting wpasupplicant: "
		start-stop-daemon --start --name $PNAME \
			--oknodo --startas $DAEMON -- -B $OPTIONS
		echo "done."
		;;
	stop)
		echo -n "Stopping wpasupplicant: "
		start-stop-daemon --stop --name $PNAME \
			--oknodo
		echo "done."
		if [ -f $PIDFILE ]; then
			rm -f $PIDFILE;
		fi		
		;;
	reload|force-reload)
		echo -n "Reloading wpasupplicant: "
		start-stop-daemon --stop --signal HUP \
			--name $PNAME
		echo "done."
		;;
	restart)
		echo -n "Restarting wpasupplicant: "
		start-stop-daemon --stop --name $PNAME \
			--retry 5 --oknodo
		if [ -f $PIDFILE ]; then
			rm -f $PIDFILE;
		fi		
		start-stop-daemon --start --name $PNAME \
			--oknodo --startas $DAEMON -- -B $OPTIONS
		echo "done."
		;;
	*)
		echo "Usage: $0 {start|stop|restart|reload|force-reload}" >&2
		exit 1
		;;
esac

exit 0

but I get following error:

Code:

# /etc/init.d/wpasupplicant stop
Stopping wpasupplicant: start-stop-daemon: need at least one of --exec, --pidfile or --user
Try `start-stop-daemon --help' for more information.
linux:~ # /etc/init.d/wpasupplicant start
Starting wpasupplicant: start-stop-daemon: need at least one of --exec, --pidfile or --user
Try `start-stop-daemon --help' for more information.

knows someone what's wrong and howto solve this problem ?

You are not fulfilling the requirements of the start-stop-daemon command. Your missing an option ... guessing by the way the script is written you need to change the line:

start-stop-daemon --start --name $PNAME --oknodo --startas $DAEMON -- -B $OPTIONS

to:

start-stop-daemon --start --name $PNAME --oknodo --startas $DAEMON -- -B $OPTIONS --pidfile $PIDFILE

the above is 1 line btw ... in the script the line is divided by the "\" but i wasnt sure if you know what that means ... just means more of the same line on the next line basically.

im guessing however as i dont know your system ... i would make a copy of your file add that and then try ... but that will only work for the start option if you want the other options of this to work you will have to add the pidfile option to the other sections as well. but see if that works and post back

thanks, I changed but still get the following error:

Code:

# /etc/init.d/wpasupplicant start
Starting wpasupplicant: start-stop-daemon: need at least one of --exec, --pidfile or --user
Try `start-stop-daemon --help' for more information.

try this on the command line: (all 1 line btw)

start-stop-daemon --start --name wpa_supplicant --oknodo --startas /usr/local/sbin/wpa_supplicant --pidfile /var/run/wpasupplicant.pid -- -B -Bw

cccc · 03-12-2006, 09:14 AM

Code:

# start-stop-daemon --start --name wpa_supplicant --oknodo --startas /usr/local/sbin/wpa_supplicant --pidfile /var/run/wpasupplicant.pid -- -B -Bw
 /usr/local/sbin/wpa_supplicantstart-stop-daemon: (null): Bad address

skog · 03-12-2006, 10:49 AM

ok i think we found your problem then.

where is wpa_supplicant installed?

try this one:
start-stop-daemon --start --name wpa_supplicant --oknodo --startas <***put-path-to-wpa_supplicant-here***> --pidfile /var/run/wpasupplicant.pid -- -B -Bw

dont put the <*** or the ***> in the command just trying to bring attention to it.

cccc · 03-12-2006, 10:59 AM

but the path is correct:

Code:

# start-stop-daemon --start --name wpa_supplicant --oknodo --startas /usr/local/sbin/wpa_supplicant --pidfile /var/run/wpasupplicant.pid -- -B -Bw
 /usr/local/sbin/wpa_supplicantstart-stop-daemon: (null): Bad address

change the --startas to --exec

start-stop-daemon --start --name wpa_supplicant --oknodo --exec /usr/local/sbin/wpa_supplicant --pidfile /var/run/wpasupplicant.pid -- -B -Bw

cccc · 03-12-2006, 12:08 PM

now I don't get any errors from the command line,
but the wpa_supplicant will be NOT executed and I cannot find any pid file

skog · 03-12-2006, 12:45 PM

did it start the wpa_supplicant program? it should start it if all the options are correct.

look with:

ps -aux | grep wpa_supplicant

skog · 03-12-2006, 12:52 PM

try this:

startproc -f -p /var/run/wpa_supplicant.pid /usr/local/sbin/wpa_supplicant -Ba

debian uses the start-stop-daemon util to start/stop services ... SuSE uses the LSB method. the above is the way SuSE does it ... im not to familiar with debs util if you just want it to work would be pretty easy to rewrite into a LSB script. but see if this works too

cccc · 03-12-2006, 01:02 PM

wpa_supplicant program won't start

Code:

# start-stop-daemon --start --name wpa_supplicant --oknodo --exec /usr/local/sbin/wpa_supplicant --pidfile /var/run/wpasupplicant.pid -- -B -Bw
linux:~ # startproc -f -p /var/run/wpa_supplicant.pid /usr/local/sbin/wpa_supplicant -Bw
linux:~ # ps -aux | grep wpa_supplicant

skog · 03-12-2006, 01:08 PM

hmmm just a sec made a post ... and i guess its not right

skog · 03-12-2006, 01:16 PM

try this:

start-stop-daemon --start --name wpa_supplicant --oknodo --exec /usr/local/sbin/wpa_supplicant --pidfile /var/run/wpasupplicant.pid -- -B -w -i ath0 -D madwifi -c /etc/wpa_supplicant.conf -dd

thanks a lot !

now it starts the wpa_supplicant program, but don't create any pid file
