connect ECONNREFUSED 127.0.0.1:21 error in node js

I'm writing a simple application in node js, and i'm having this problem:

Error: connect ECONNREFUSED 127.0.0.1:21
    at Object.exports._errnoException (util.js:1034:11)
    at exports._exceptionWithHostPort (util.js:1057:20)
    at TCPConnectWrap.afterConnect [as oncomplete] (net.js:1099:14)

This is the script:

var Client = require('ftp');
var fs = require('fs');


  var c = new Client();
  c.on('ready', function() {
    c.get('/foo/foo1.txt', function(err, stream) {
      if (err) throw err;
      stream.once('close', function() { c.end(); });
      stream.pipe(fs.createWriteStream('foo.local-copy.txt'));
    });
  });
  c.connect('MYIP',21,false,'none','user','password',10000,10000,10000);

  c.end();

what's wrong?
