Hi Guys,

I have an active wireless connection on my Linux box (Kubuntu 13.10). When I manually ping Google with ping www.google.com at the command prompt I get the following output: 


PING www.google.com (173.194.34.144) 56(84) bytes of data.
64 bytes from lhr14s21-in-f16.1e100.net (173.194.34.144): icmp_seq=1 t

But when I use Net::Ping in a perl script like this: 

    my $p = Net::Ping->new("tcp", 2);
    # With or without this next line.
    $p->port_number(getservbyname("http", "tcp"));
    if ($p->ping("www.google.com")) {
        print "Host is reachable\n";
        return 1;
    } else {
        print "Host is not reachable\n";
        return 0;
    }

I get "Host is not reachable" rather than the "Host is reachable" suggested by running ping manually.

What is happening here?

Thanks very much.

Steve.
