Quand mon modem ADSL chauffait et plantait, reload automatique du réseau. Novembre 2005.

netreload.sh

#!/bin/sh
LSPING=`ping -c 3 www.free.fr 2>&1`
PINGRES=`echo $LSPING | egrep "100% packet loss|unknown"`
if  [ "$PINGRES" != "" ]; then
        echo "--- START NET RELOAD " >> /var/log/netreload
        poff dsl-provider
        sleep 45
        /sbin/mii-tool -F 10baseT-HD eth1
        pon dsl-provider 
        echo "Reason : " >> /var/log/netreload
        date -u >> /var/log/netreload
        echo $LSPING >> /var/log/netreload
        echo "--- END NET RELOAD" >> /var/log/netreload
fi;
