A co treba nejake sofistikovanejsi reseni? Treba Nagios.

Jinak zkus wmpiki, je to hezka vec, ale nehraje.

while true 
do
  ping neco -n 1 -w x || play neco
  sleep 30
done

já používám tento scriptík

#!/bin/bash

laststate=-1
timeout=5
sleeptime=5s

echo "Watchdog for $1"
while true
do
        ping $1 -i $timeout -w $timeout -c 1 > /dev/null 2> /dev/null
        result=$?
        if [ $laststate != $result ]; then
                date=`date`
                case "$result" in
                        0)
                                echo "$date : Host $1 is up"
                                playwave /usr/share/sounds/KDE_Beep_Connect.wav >/dev/null 2>/dev/null
                                ;;
                        1)      echo "$date : Host $1 is down"
                                playwave /usr/share/sounds/KDE_Glass_Break.ogg >/dev/null 2>/dev/null
                                ;;
                esac
        fi
        laststate=$result
        sleep $sleeptime
done

Pomohlo by tohle?

-w deadline
Specify a timeout, in seconds, before ping exits regardless of how many packets have been sent or received. In this case ping does not stop after count packet are sent, it waits either for deadline expire or until count probes are answered or for some error notification from network.

-W timeout
Time to wait for a response, in seconds. The option affects only timeout in absense of any responses, otherwise ping waits for two RTTs.
