This reminds me of a script I wrote long ago that could be helpful in this 
sort of situation:


#!/usr/bin/perl
# sping - ping with an audible sound for each echo-reply

$play = "/usr/bin/play";
# omitting the part where I listed a bunch of soundfiles
# and picked one randomly -- just pick a good one here.
$soundfile = "/usr/share/sounds/pop.wav";

$ping = "/bin/ping";

@args = @ARGV;
open (PING, "$ping @args |") or die "Can't ping @args\n";
select STDERR; $|=1; select STDOUT;
$|=1;
while (<PING>) {
    print;
    if (/ bytes from /) {
        system($cmd) and printf("%c", 7); # beep if the play fails
    }
}
