Im currenlty using a Redhat Linux and the PING command there seems to also "HANG" on unreachable machines

Did you specify a timeout period for ping? You can use -t to tell ping when you want it to exit. Here's some code that returns true if the remote machine pings at least once in 7 seconds:

sub ping {
  my $ip = shift;
  my $p = `/sbin/ping -c 5 -t 7 $ip | /usr/bin/grep 'packet loss'`;
  unless ( $p =~ /(\d+)% packet loss/ ) {
    die ( "Bad Response:\n$p\n" );
  }
  my $loss = $1;
  print "Loss = $1 ";
  return ( $loss != 100 );
}
