通过 TCP 远程连接 [英] Remoting connection over TCP

问题描述

我已经构建了远程处理服务器和客户端.服务器设置如下:

I've got a remoting server and client built. The server is set up as such:

BinaryServerFormatterSinkProvider serverProv = 
    new BinaryServerFormatterSinkProvider();
serverProv.TypeFilterLevel = TypeFilterLevel.Full;
BinaryClientFormatterSinkProvider clientProv = 
    new BinaryClientFormatterSinkProvider();

IDictionary props = new Hashtable();
props["port"] = port;

TcpChannel channel = new TcpChannel( props, clientProv, serverProv );

ChannelServices.RegisterChannel( channel, false );

RemotingConfiguration.RegisterWellKnownServiceType( typeof( Controller ),
    "Controller", WellKnownObjectMode.Singleton );

客户端设置如下:

ChannelServices.RegisterChannel( new TcpChannel( 0 ), false );
m_Controller = (Controller)RemotingServices.Connect( typeof( Controller ), 
      "tcp://" + ip + ":2594/Controller" );

当我尝试从 IP 指定为localhost"的同一台计算机连接到服务器时，它连接正常.但是，当我尝试从远程计算机而不是 LAN 进行连接时，鉴于服务器的 IP 地址，经过漫长的等待后，我在客户端上收到以下异常:

When I try to connect to the server from the same computer with the IP specified as 'localhost,' it connects fine. However, when I try to connect from a remote computer, not on the LAN, given the server's IP address, I receive the following exception on the client after a long wait:

A connection attempt failed because the connected party did not properly
respond after a period of time

我该如何解决这个问题?我确定这是一个配置问题，因为端口在服务器上正确转发并且没有防火墙处于活动状态.

How can I resolve this? I'm sure it's a configuration problem because the ports are forwarded properly on the server and there is no firewall active.

谢谢

推荐答案

这个问题已经有一个月了，但仍然如此:

This question is a month old, but none the less:

嗅探服务器(最好也包括客户端)上的流量应该能让您更深入地了解正在发生的事情.

Sniffing the traffic on the server (and preferably, on the client as well) should give you more insight as to what's going on.

对于这项工作，我推荐 Packetyzer，这是一款非常友好的 Windows 数据包嗅探器.

For the job I recommend Packetyzer, a very friendly packet sniffer for Windows.
