TCP端口扫描，可以获得指定IP段内的主机名，mac地址，存活端口，并将这些信息保存在SQLITE数据库，下次可以直接读取数据库信息，移值性好！(CP port scan, you can get within the segment specified IP host name, mac address, survival ports, and the information stored in the SQLITE database, the next can be read directly, transfer value is good!)

说明：  基于 异步选择模型的聊天程序，简单实现服务器和客户端的对话(Select model based on asynchronous chat program, simple implementation of server and client dialogue)

WINPCAP 抓包工具，可以用来抓包等功能，十分简单的代码，可以直接使用(WINPCAP tools)

用vc实现的sniffer，没有使用winsock与winpcap。十分具有学习价值！(Vc realize with the sniffer, did not use winsock with winpcap. Very much with learning the value of!)

说明：  基于EXOSIP协议的SIP软终端，可以实现终端向代理服务器的注册请求(SIP-based softphone EXOSIP agreement can be achieved terminal registration request to the proxy server)
