How to install Socket.io on hosting?

Question

Node.js

Good afternoon.
I'm trying to install socket.io on the hosting, but it gives the following
server.js error:

var io = require('socket.io')(6001);
io.on('connection', function(socket){
  socket.on('channelfxer', function(mychanel){
    socket.join(mychanel);
  });
  socket.on('message', function(data){
    socket.broadcast.emit('message',data);
  });

  socket.on('readed', function(data){
    socket.to(data.room).emit('readed',data);
  });

socket.on('disconnect', function(){ });
});

error when I run:

events.js:182
      throw er; // Unhandled 'error' event
      ^
Error: listen EPERM :::6001
    at Object.exports._errnoException (util.js:1016:11)

I realized that the reason is in the port, even when I remove the port in server.js. Everything starts without errors, just does not reach the connection.
How can I connect this?
Maybe it's somehow possible to connect from the locale?

Answer 1

Most likely the port is occupied by someone, look
netstat -tulpn | grep --color :6001
