Hi Kiril
If I read your script correctly then there might be a little glitch

Once you have wasted all the hosts in your list you restart your network,
although IMHO this only means that host3.com cannot be pinged.
I believe you want to do something like
#!bin/bash
PING_REMOTE_HOSTS="host1.com host2.com host3.com"
UP=0
while true
do
while [$UP -eq 0]
do
sleep 120
UP = 1 # this would break the inner loop
for HOST in $PING_REMOTE_HOSTS
do
ping $HOST -qc 1 >/dev/null 2>&1
UP &= $? # if any ping returns 0 it is OK
done
done
echo "network is down. restarting..."
/etc/init.d/network reload
sleep 60
done
I have not tested this :-(
