完成端口的简单例子。自己写的，很好，很强大。

UDPSocket 简单的UDP通信,可以参考改进-UDPSocket simple UDP communications, can refer to improved

Microsoft VC++7.0 Change 具体使用解压后即可得知-Microsoft VC 7.0 Change specific use to get unpacked

http通讯协议，实现可以实现文件的上传与下载-http communication protocol, can realize the upload and download files

简单清晰，对你很有帮助的客户端FTP程序-simple and clear, helpful to your client FTP procedures

代理服务器（Proxy Server）软件是一种常用的网络软件，常用于网吧、学校、公司等使用局域网的机构中。代理服务器的功能是接受过个客户端的网络请求，分析请求的内容，从远程的服务器上获取信息后返回给客户计算机。本例实现一个比较简单的HTTP代理服务器程序。-proxy server (Proxy Server) software is a common network software commonly used in Internet cafes, schools, companies use LAN institutions. Proxy server function is accepted-client network request, analyze the content of the request from the remote server access to the information and returned to the client computer. The cases to achieve a relatively simple HTTP proxy server.

又一款局域网聊天程序，适用于delphi5,只有用了Rxlib2.75中的两个控件，一个是用来做TrayIcon的(TRxTrayIcon)，还有一个是用来选颜色的(TColorComboBox)， 大家可以到Rxlib专栏中下载这个控件-another model LAN chatting procedures applicable to 3.0-5.0 Only a Rxlib2.75 the two controls, one is used for TrayIcon (TRxTrayIcon), there is an election to the color of (TColorComboBox), Rxlib You can download this column Controls

WINSOCK程序设计共分为客户端和服务器端程序两部分，要求实现功能：服务器端要能监听客户端连接请求，为客户端的连接请求建立SOCKET队列，处理各个客户端发送的数据，并向响应客户端发送应答信息，更新服务器端的端口号。-Winsock program design consists of client and server-side procedures in two parts, requires the function : server can be monitored to client requests for the client to establish a link SOCKET queue handle all the client to send data to respond to a client sent response information update service Works on the port side.

用来进行端口转发。端口映射等功能都可以 C语言源码 格式 110 127.0.0.1 112 本地端口 转发IP 转发端口-Used for port forwarding. Such as port mapping functions can be C language source code format 110 127.0.0.1 112 local port forwarding IP forwarding port

本程序只对一个IP地址进行，如果要对一段IP进行测试，简单修改程序即可。可将发送放在单独的进程 里(使用fork（）），send_icmp里做成循环，每次重新初始化struct sockaddr_in。那么对接收到的数据 进行分析的proc_icmp（）将多一道对IP报头ip->src字段的判断。-this procedure only a pair of IP addresses, IP to a test, a simple change procedures. This can be placed on a separate process (the use of fork ()), causing Lane send_icmp cycle, each re-initialization struct sockaddr_in. Then Butt received the data analysis proc_icmp () will more than one pair of IP header ip-gt; Src field judgment.
