Eu gostaria de criar um script que tente me conectar ao wifi especificado pelo meu conf wpa_supplicant e, se ele falhar, crie uma rede ad-hoc. Mas eu estou lutando com isso.
Aqui está o que faço por agora:
#!/bin/bash
# create adhoc network function
createAdHocNetwork(){
echo "Creating ad-hoc network"
ifconfig wlan0 down
iwconfig wlan0 mode ad-hoc
iwconfig wlan0 essid AccessPoint
ifconfig wlan0 11.0.0.1 netmask 255.255.255.0 up
echo "Ad-hoc network created"
}
# connect to wifi function
connect(){
echo "Trying to connect to configured wifi"
ifdown wlan0
wpa_supplicant -B -i wlan0 -c /home/pi/pics/wpa_supplicant.conf
ifup wlan0
echo "Wifi configured"
}
echo "================================="
echo "Wifi setup"
echo "================================="
connect
echo "Checking connectivity..."
sleep 5s
ping -c 5 -I wlan0 google.com > /dev/null 2>&1
PINGSTATUS=$?
echo "Status"
echo $PINGSTATUS
if [ $PINGSTATUS -eq 0 ];
then
echo "Connected to WiFi"
else
echo "Wifi not connected, fallback to ad-hoc"
createAdHocNetwork
fi
exit 0
Parece que funciona para se conectar ao Wi-Fi configurado, mas não para ad-hoc.
Aqui está meu /etc/network/interfaces
:
# start interfaces upon start of the system
auto lo wlan0
# register loopback interface
iface lo inet loopback
# use dhcp and allow interface to be started when kernel detects a hotplug event
allow-hotplug eth0
iface eth0 inet dhcp
# use manual ip configuration for wlan0 interface and allow hotplug as well
allow-hotplug wlan0
iface wlan0 inet dhcp
E meu /etc/dhcp/dhcpd.conf
:
ddns-update-style interim;
default-lease-time 600;
max-lease-time 7200;
authoritative;
log-facility local7;
subnet 11.0.0.0 netmask 255.255.255.0 {
range 11.0.0.2 11.0.0.150;
}
Eu posso ver a rede ad-hoc de outro computador, mas não consigo me conectar a ela, alguma idéia?
Atenciosamente
