Help with wireless script

[zachtib]

Im writing a script to gui-fy connection to out wireless network at school.

The GUI is basically just a frontend for wpa_supplicant, written in bash

exerpt:
CONNECTED="false"
WPA_STATUS=""
WPA_LOG=$HOME/wpa.log
(
echo "10"
gnome-terminal --command="sudo wpa_supplicant -w -i${WIFI_DEV} -D${WIFI_DRV} -c${CONF_FILE} -dd"
while [ ${CONNECTED}=="false" ]; do
sudo wpa_cli status &> $WPA_LOG
#echo "# Reading" ; sleep 1
exec < $WPA_LOG
while read line
do
WPA_STATUS="$line"
done
#WPA_STATUS=`sudo wpa_cli status`
gnome-terminal --command="sudo wpa_supplicant -w -i${WIFI_DEV} -D${WIFI_DRV} -c${CONF_FILE} -dd"
echo "# $WPA_STATUS" ; sleep 10
done
)|
zenity --progress --title="UofLConnect" \
--text="Connecting" --percentage=0 \
--width=500 --pulsate

if [ "$?" = -1 ] ;
then
zenity --error --text="Connection cancelled."
sudo killall wpa_supplicant
exit 1
fi

the problem is, it never authenticates while the gui is up. If I cancel the window once it has started, it will finish authenticating. I think the wpa_cli calls are interupting wpa_supplicant. Does anyone know a better way to communicate with wpa_supplicant. Also, is there a way to make this line:
gnome-terminal --command="sudo wpa_supplicant -w -i${WIFI_DEV} -D${WIFI_DRV} -c${CONF_FILE} -dd"
pop up a gksudo dialog and then background instead of my current solution, which pops up a gnome-terminal.
Connecting to the wireless at my school is a pain, and I'm trying to make it easier on people. If anyone has any suggestions, I's appreciate them. If anyone wants, I'll post the full source code

Try gnome-sudo command
That will get you a sudo dialog like from the menus.
