title: Socket.io not sending a message to all connected sockets
body: <p>I'm trying out node.js and socket.io. I wan't to use to remove a ping function I have to get updates from my server. Here is an example code of what I'm doing:</p>
  
  <pre><code>var app = require('http').createServer(),
      io  = require('socket.io').listen(app),
      cp  = require('child_process');
  
  app.listen(8080);
  
  //I check a global value for all the connected users from the php command line
  var t = setInterval(function(){
    cp.exec('/usr/bin/php /Users/crear/Projects/MandaFree/symfony api:getRemainingMessages',
      function(err, stdout){
        if (err) {
          io.sockets.emit('error', 'An error ocurred while running child process.');
        } else {
          io.sockets.emit('change', stdout);
        }
        console.log('Remaining messages: ' + stdout);
      });
    }, 3000);
  
  var remaining =  io.of('/getRemainingMessages')
    .on('connection', function(socket){
      socket.on('disconnect', function(){});
    });
  </code></pre>
  
  <p>The Issue here, is that when I call io.sockets.emit() the debug console tells me it is doing something, but it looks like it is not getting to the clients. Because they are doing nothing.</p>
  
  <p>I use to have one interval for every connected client, and when I used socket.emit() it did worked. But it is not the optimal solution.</p>
  
  <p><strong>UPDATE:</strong>
  Here is my client side code.</p>
  
  <pre><code>var remaining = io.connect('http://127.0.0.1:8080/getRemainingMessages');
  remaining.on('change', function(data){
    console.log('Remaining messages: ' + data );
    $('#count').html(data);
  });
  remaining.on('error', function(error){
    console.log(error);
  });
  </code></pre>
