局域网监控系统采用vc++6.0编写，需要oracle数据库(LAN monitoring system)

采用syn的扫描方式对一个网段的ip进行扫描，图形界面(Syn scan mode using a segment of ip scanning, graphical interface)

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 )

IPE打包机，可以讲IP流的数据包打包成TS流数据包(IPE balers, you can speak IP flow data is packaged into a TS stream packet)

对于网络开发包的详细解释，包括了libcap和libnid等(For a detailed explanation of the network development kit, including the libcap and libnid of)

VC++实现类似于QQ文件传输功能的文件发送与接收程序示例，分为服务端和客户端，客户端首次接收数据，将判断文件包大小，数据包中一定包含完整的数据包结构信息，数据不一定完整；读取数据包的大小，包含数据包结构大小和数据大小，之前接收的数据与现在接收的数据能够构成至少一个完整的数据包，文件接收完毕则设置结束标记，若终止的连接，则弹出窗口告诉用户，对方终止了文件传送。 　　服务端程序是比较简单的，基本是复制文件数据、判断文件是否传递成功、等待对方收受发送任务或取消发送任务，分包继续发送文件等功能(VC++ implementation is similar to QQ file transfer capabilities to send and receive files program examples, divided into server and client, the client receives the first data packet to determine the file size, the packet must contain the complete information packet structure, the data is not must complete reading packet size, including the size and structure of the data packet size, and previously received data received data can now constitute at least one complete packet, the file has been received then set the mark, if the connection is terminated, the pop-up window telling the user, the other party to terminate the file transfer. Server program is relatively simple, basically copying the file data, to determine whether the file transfer is successful, waiting for the other to accept or cancel the sending task sends tasks, subcontractors continue to send files and other functions )

说明：  远程开机的程序，有mfc，vc++,非常实用(Remote boot-consuming procedures, mfc, vc++, Very useful)

TCP 发送模块 一点小代码`````` 仅仅当做参考(TCP Send Module)

上传下载源码，支持 断点续传，使用 libcurl(Upload and download the source code, support for HTTP, use libcurl)

TCP通信示例程序，很好用的网络通信例程(TCP communication sample program, the good network communication routines)
