# Ownership: root:root 
# Permissions:  755 
IP="192.168.1.72"
LOGFILE="/tmp/myserver.log"

while :
do
        if ping -c 1 $IP > /dev/null 2>&1
        then
                echo "$(date) online" >> $LOGFILE
        else
                echo "$(date) OFFLINE" >> $LOGFILE
        fi
        sleep 60
done
