client 无法监听connect事件？

var events = require('events');
var net = require('net');
var channel = new events.EventEmitter();
channel.clients = {};
channel.subscriptions = {};

channel.on('join',function(id,client){
    console.log('connect');
    this.clients[id] = client;
    this.subscriptions[id] = function(senderId,message){
        console.log(message);
        if(id != senderId){
            this.clients[id].write(message);
        }
    };
    this.on('broadcast',this.subscriptions[id]);
});

var server =  net.createServer(function(client){
    var id = client.remoteAddress+':'+client.remotePort;
    client.on('connect',function(){
        console.log('client connect');
        channel.emit('join',id,client);
    });
    client.on('data',function(data){
        data = data.toString();
        console.log(data);
        channel.emit('broadcast',id,data);
    });
});
server.listen(8887);

这句始终不被执行,为什么？ client.on('connect',function(){ console.log('client connect'); channel.emit('join',id,client); });

net.Server现在的EventEmitter有close, connection, error,listening，net.Socket有connect，你把net.createServer换成net.createSocket就可以出发connect。你这个功能用socket.io写不是更好么？
