网络通信程序,实现TCP和UDP通信,可互发消息

程序说明: 1.程序采用网上介绍的方法实现最基本的P2P方式通讯.模拟实现即时消息互发. 2.P2P通讯说明: 1).网关类型是在理想状态下.即非对称型NAT. 2).同在一个内网的两个CLIENT端通讯时,如果网关NAT不支持环回,将会失败. 文件目录说明: tQServer:程序服务端,请将其放在公网上运行. tQClient:程序客户端,可以在不同的内网中运行登录连接到服务端. Common:公共协议文件夹 本程序只是实现简单的P2P互发消息.完成的比较粗糙,更多功能欢迎朋友们更新完善-procedures : 1. Online procedures introduced by the most basic method of peer-to-peer communication. Simulation made instant messaging each other. 2.P2P communications Note : 1). Gateway is the ideal type of state. That is non-symmetric NAT. 2). In the same period net CLIENT-2 communications, if not support NAT Gateway Circular, will fail. directory : tQServer :-service procedures, I would be grateful if the public on its Internet. tQClient : clients, in different operations within the network login to connect to the server. Common : Public the agreement folder procedure is a simple peer-to-peer updates. completion of the rougher, more functional friends welcome update perfect

用java实现的Tftp(Sftp)客户端与服务器程序。在这个程序中用到了一个“状态”的机制：客户端与服务器端在开始运行时有相同的状态，通过用户的输入或程序内部运行的机制，程序可以转到不同的状态，在不同的状态下程序实现了不同的功能 -Using java realized Tftp (Sftp) client and server program. In this procedure used a state of the mechanism: client and server-side run-time in the beginning has the same state, through user input or program running internal mechanisms, procedures can be transferred to a different state, in a different state under the procedures realize the different functions

大家都知道ftp把，这是c++上的ftp编程，指导性的东西，，大家一起共享-We all know that the ftp, which is c++ The ftp program, guiding the things we can work together to share

一个代码很规范的程序，实现对目标IP的主机进行端口扫描，其中线程数在程序中内嵌，无法自定义。可以自定义要扫描的端口号，有操作界面，操作简单，运行流畅，不会出现运行过慢的情况，不会卡顿，很好的例子。源码中有详细的注释。

最新版本V1.032版本的TCP/UDP调试工具,修改了上一版本的bug，提供应用程序接口,帮助学习TCP/UDP协议栈，尤其对开发带有TCP/UDP接口的硬件设备很实用，相当于串口超级终端的功能(可以叫做网口超级终端!)-The latest version V1.032 version of TCP/UDP debugging tools, modify the previous version of one bug, to provide application programming interfaces to help learning TCP/UDP protocol stack, in particular on the development of a TCP/UDP interface hardware device is very useful, very in serial HyperTerminal function (can be called network HyperTerminal mouth!)
