说明：  网络安全编程，VC++环境，原始套接字，源代码文件，某些系统可能不支持原始套接字，这只是一个原理性的说明(Network security programming, VC++ environment, raw sockets, source code files, some systems may not support raw sockets, this is only a schematic description of)

c06tb套利交易策略源码，源码为人人宽客编写分享(C06tb arbitrage strategy source code, source code for everyone to share quants written)

使C++语言编程，实现双机在联网条件下通过IP地址实现通信。(With C++,we can make two computers commnicate with each other when they are on the Internet.)

文件异步下载程序vb示例(document asynchronous sample download vb)

用VC语言开发的traceroute，深层次的socket编程(traceroute)

Network transmission

NAT(Network Address Translators)，网络地址转换：网络地址转换是在IP地址日益缺乏的情况下产生的，它的主要目的就是为了能够地址重用。NAT分为两大类，基本的NAT和NAPT(Network Address/Port Translator)。(The principle and implementation of UDP NAT through P2P )

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!)
