I am having a timeout example code problem, modified code is below:

class connect_handler
{
public:
  connect_handler(io_service& ios)
    : io_service_(ios),
      timer_(ios),
      socket_(ios)
  {
    socket_.async_connect(
        tcp::endpoint(boost::asio::ip::address_v4::loopback(), 32123),
        boost::bind(&connect_handler::handle_connect, this,
          boost::asio::placeholders::error));

    timer_.expires_from_now(boost::posix_time::seconds(5));
    timer_.async_wait(boost::bind(&connect_handler::close, this));
  }

  void handle_connect(const boost::system::error_code& err)
  {
    if (err)
    {
      std::cout << "Connect error: " << err.message() << "\n";
    }
    e
lse
    {

     // We need to cancel the timeout since we have connected.

     timer_.cancel(); // < Fires the timer regardless. Because we are calling cancel() from inside an io_service call???

      std::cout << "Successful connection\n";
    }
  }

  void close()
  {
    socket_.close();
  }

private:
  io_service& io_service_;
  deadline_timer timer_;
  tcp::socket socket_;
};
