Connecting to TCP server from flash socket on local environment - actionscript-3

Question

I have made a swf file for distribution version to clients to use on their computer.
and I have a TCP server connected from that swf file.
before testing it, I have read some articles related to policy file on adobe website
I tried to test that, and have used the nodejs and swf file for that
but I failed. here is how it looks like.
crossdomain.xml on root
<?xml version="1.0"?>
<!DOCTYPE cross-domain-policy SYSTEM "http://www.adobe.com/xml/dtds/cross-domain-policy.dtd">
<cross-domain-policy>
<allow-access-from domain="*" to-ports="3000" />
</cross-domain-policy>
tcp_server.js
var sys = require("sys"),
net = require("net");
var server = net.createServer(function(stream) {
stream.addListener("connect", function() {
sys.puts("Client connected");
stream.write("hello\r\n");
});
stream.addListener("data", function(data) {
sys.puts("Received from client: " + data);
stream.write(data);
});
stream.addListener("end", function() {
sys.puts("Client disconnected");
stream.write("goodbye\r\n");
stream.end();
});
});
server.listen(3000, "localhost");
swf file on local
import flash.net.Socket;
var socket:Socket = new Socket();
trace(socket);
trace("a socket is created");
socket.connect("localhost", 3000);
It seems like a long code, anyway
I tested it, and got this error
for wrong code, the policy file at xmlsocket://localhost:843 will be ignored
I can't find what is wrong with my code,
If you know that, Please let me know
Thanks for who reads this question
Have a nice day.

Flash Player checks for a policy file server (port 843 by default), or if necessary, on the socket you're opening (for you, port 3000).
A policy file server is a socket which responds to a with a valid policy file. What's happening with your message is likely that it's sending its request and getting something other than a policy file back, hence invalid syntax from port 3000.
Programming socket to return your crossdomain.xml file over the socket when it got a <policy-file-request/> message.
