Comment 56 for bug 50430

Hello,

This is the script i'm using :

/etc/network/if-up.d/net_is_configured :

#!/bin/sh
# Testing if network is up before continuing
network=`route -n | sed -ne '/^224/d' -e '/^127/d' -e '/^[0-9]/p'`;
timeout=0
while [ "${network}" = "" ] && [ ${timeout} -le 20 ]
        do network=`route -n | sed -ne '/^224/d' -e '/^127/d' -e '/^[0-9]/p'`;
        echo -n ".";
        timeout=$((${timeout} + 1));
        sleep 1;
done
if [ ${timeout} -ge 20 ];then
        echo " Pas de connexion réseau";
else
        echo " Done";
fi

Hope this will help you
