为了提高扫描速度，本程序采用了多线程技术和非阻塞I/O的技术。程序的主界面是一个对话框-order to improve scanning speed, the program uses a multi-threading technology and non-blocking I/O technology. Proceedings of the main interface is a dialog

IP数据包捕获类，能使网卡工作在混杂模式，监听来自网络的所有数据包-IP packet capture category, enable the network card in promiscuous mode, monitoring from the network all packets

利用TCP IP实现简单的客户服务器模式-Easy to use implementation of the TCP IP client-server model

Client程序同样分别创建一个TCP socket 和一个UDP socket，首先client使用TCP socket连接TCP Server。 连接成功后显示提示信息； 然后client端向TCP Server发送“GET UDP PORT”字符串，Server收到后向client回送自己的UDP Server 端口号（即Client端仅知道TCP Server的端口号而不知道UDP Server的端口号）； client在收到UDP Server的端口号后, 为用户显示3个选项： 1．“Get current time（TCP）”服务器时间 2．“Echo Mode（UDP）”回显6 3．“Exit the program”. -Client program also creates a TCP socket, respectively, and a UDP socket, the first client to use TCP socket connection TCP Server. After a successful connection displays a prompt message and then client-side to the TCP Server sends " GET UDP PORT" string, Server receipt back to the client to send their UDP Server port number (ie, Client-side only to know the TCP Server" s UDP port number do not know Server" s port number) client received UDP Server port number, in order to the user three options: 1. " Get current time (TCP)" server time 2. " Echo Mode (UDP)" echo 63. " Exit the program" .

简单的聊天程序，不完善版，注释比较少，因为开发的时候时间比较急，所以没加太多注释。-simple procedures, incomplete version of the Notes is relatively small, because of the development time is more urgent, Therefore, the Notes have not too many.

用来通过HTTP协议下载的程序，支持断点续传和多线程下载。 注意，该程序一次只能下载一个任务，那个列表虽然可以拉很多进去，不过是摆设。-HTTP protocol to download through the procedures, support HTTP download and multithreading. Note that this procedure can only be downloaded once a task that although the list can pull into the lot, but yes display.

一个“Ping”程序，主要包括：填写一个ICMP回响请求报文，以数据报的方式向目标主机发送，然后接收目标主机回送的ICMP回响应答报文，若成功，给出提示信息。-a "Ping" procedures, including : a complete response ICMP request packet, Data reported to the mainframe sent to the target and then receiving sent back to the mainframe objectives of the ICMP response Reply message, If successful, and given a message.
