Node.js Tcp服务器EACCESS

Question

Using net to create a TCP server on Node.js on a windows machine

var net = require('net');
var host = 'localhost';
var port = '7171';

net.createServer(function(socket) {
    console.log('CONNECTED - ' + socket.remoteAddress);
}).listen(host, port);

But Im getting this EACCES error even if I run the node console as admin with control shift click.

events.js:72
        throw er; // Unhandled 'error' event
              ^
Error: listen EACCES
    at errnoException (net.js:904:11)

    at Function.Module._load (module.js:312:12)
    at Function.Module.runMain (module.js:497:10)

Since at windows I normally dont have to deal with these kind of privilegies issues I dont know what to do

Answer 1

You have your params backward:

.listen(host, port);

should be

.listen(port, host);

Also I'd probably pass the port number as a number instead of a string, but either appears to work.

Answer 2

Docs: http://nodejs.org/api/net.html#net_server_listen_port_host_backlog_callback

server.listen() takes a port, with optional host. Signature is listen(port, [host], [backlog], [callback]). I think this is what you want:

var net = require('net');
var port = '7171';

net.createServer(function(socket) {
    console.log('CONNECTED - ' + socket.remoteAddress);
}).listen(port);
