heh, sorry for opening this again, I did this: while true; do ping -c 3 8.8.8.8 | grep "0 received" && mplayer -volume 150 -loop 0 ~/Music/siren_alert.mp3 || echo Ping OK : $(date) done This way only when it does not receive 3 consecutive pings (with "-c 3") it alerts me. If it misses only one or two everything is fine.
