Greetings williambender

I don't have tcpdump installed, so I don't know that I can check it. But would the following possibly work 

use Net::RawIP;

my $packet = new Net::RawIP();

$packet->set({
        ip => {
                saddr => "192.168.10.10",
                daddr => "192.168.10.20"
            },
        udp => {
               check => 0,
               source => 6544,
               dest => 514,
               data => 'test123'
            }
        });

Hey. I'm not completely useless. I can be used as a bad example.
