动态域名解析服务器

本实例是用java实现的网络五子棋程序。程序由两个部分组成：一部分为服务器端，另一部分为五子棋客户端。其中服务器端以消息方式完成客户端的管理，客户端支持对弈和聊天。-example is the realization of the network java 331 procedures. Procedures by the two parts : part of the server side and the other 331 for the client. Which news server to the client is accomplished management, client support players and chat.

模仿RealVNC412编的，查看服务端的盘符文件内容并且看到感兴趣的可以文件下载下来，同时也可以上传文件到服务端任意位置的通信和文件操作程序，支持单个文件以及一个目录下的所有文件上传或下载。照搬realVnc的网络通信功能，以及支持多客户连接功能。客户端也尽量模仿realvnc的客户端，包括断线重连，属性页对话框，以及主体交互对话框，都是直接用SDK编的，当然也是抄的RealVNC.客户端以及服务端源代码文件夹下的common文件夹是静态库文件，有的是照搬RealVNC412源码，有的是模仿写的。-Imitate RealVNC412 compiled to view the contents of the file server of the letter and see the files of interest can be downloaded, but can also upload files to a server anywhere in the communications and documentation procedures to support a single file and a directory of all file upload or download. Copy realVnc network communications capabilities, and support for multi-client connectivity. Client also try to imitate realvnc clients, including the disconnection re-connected, the property page dialog box, as well as the main interactive dialog box, and are directly compiled with the SDK, of course, is also a copy of RealVNC. Client-side and server-side source code folder under the common folder is a static library file, either copy RealV

基于角色的用户验证. 这个程序重点写了四个pages以实现这些功能：增加用户，给用户指派角色，给用户移除角色及管理角色。-role-based user authentication. Focus on the process of writing four pages to achieve these functions : increase users, the role assigned to the user to remove the role of users and management roles.

利用哈希运算产生服务端和客户端的通信密钥- Produces the service end and the customer end correspondence key using the Hasche operation

包含tcp和udp通信代码，服务器端客户端代码用于传输指令消息，实现了端对端，定时发送多次发送，网络中计算机进行通信的一种方法。应用程序通过调用系统提供的socket库函数很容易实现网络里计算机的通信，并且在android端读取信息显示的功能，并已投入使用，希望对开发者有帮助。
