Net Ping Not Timing Out

[chitownclone]

Anyone have an idea why some timeout is not working on some domain names that I Ping? There are certain DNs that are not active that take 20 seconds to timeout, even though I have it set to 1 or 2 seconds (I tried setting the timeout 2 different ways).

Is it the number of Pings it is sending before timeout or something else?

Thanks

$p = Net::Ping->new("syn");
$p->{port_num} = getservbyname("http", "tcp");
$p->ping($url, 1);
($host,$rtt,$ip) = $p->ack; 
$p->close();


$p = Net::Ping->new("syn", 2);
$p->{port_num} = getservbyname("http", "tcp");
$p->ping($url);
($host,$rtt,$ip) = $p->ack; 
$p->close();

I think its because the Net-Ping module sets the ping protocol as "TCP" which either way, it takes longer to complete, so it takes longer to timeout. Try to set the protocol as "ICMP" when you create the ping object and see what happens.
