Hi, I'm trying to write a Perl script under Windows to perform parallel ping.
I would like to use one thread for each host that I have to ping.
I'm using Net::Ping and threads modules.
Threads main subroutine is something like that: 
sub PingTest {
    my ($myhost, $protocol, $timeout) = @_;
    my $p = Net::Ping->new($protocol, $timeout);
    
    if (!$p->ping($myhost)) {
        print "Unreachable\n";
    }
    else {
        print "Reachable\n";
    }
    
    $p->close();
}

My problem is that if I use "tcp" as $protocol some hosts result Unreachable (but with windows command "ping" same hosts are reachable);
If I use "icmp" as $protocol all hosts are reachable (but with windows command "ping" some hosts are not reachable or not exist);
Have you got any suggests?
Thanks
G.
