telnet反向连接

服务器端通过socket()系统调用创建一个Socket数组后(即设定了接受连接客户的最大数目)，与指定的本地端口绑定bind()，就可以在端口进行侦听listen()。如果有客户端连接请求，则在数组中选择一个空Socket，将客户端地址赋给这个Socket。然后登录成功的客户就可以在服务器上聊天了。-Server-side through the socket () system call to create a Socket after the array (that is set to receive the maximum number of connected customers), with a specified local port to bind bind (), will be able to listen on port listen (). If the client has to connect the request, then select an empty array Socket, the client address assigned to the Socket. And then sign in the success of customers can chat on the server.

通过SNMP查询来得到网卡信息，做软件授权可参考该功能-Through SNMP queries to obtain card information, the software is authorized to make reference to the function

用VB写的一个代理服务器程序，功能也比较多，适合大家观摩使用。-Using VB to write a proxy server procedures, functions are more suitable to observe the use of everyone.

这是我们开发一个报警服务, 从串口读报警, 用TCP把报警发送到客户端, 包括完成端口通讯, ADO数据库访问, 串口通讯等类, 数据库表我就不提供了, AlarmService /RegServer 安装服务, AlarmService /Start 开始服务, AlarmService /Stop 结束服务, AlarmService /UnRegServer 卸载服务-This is our development of an alarm service, alarm time from the serial port, using TCP to the police sent to the client, including the completion of port communications, ADO database access, serial communications, and other categories, database table I do not provide, AlarmService/RegServer installation services, AlarmService/Start to start service, AlarmService/Stop the end of services, AlarmService/UnRegServer unloading services

CUdpSocket是为了简化发送，解析UDP 数据报所提供的一个基类。这个类封装了基于SOCK_DGRAM的大部分基本操作。这个类提供两种工作模式，一种是和实际处理UDP 数据报的功能紧耦合，这需要通过继承实现，同时设置workmode 为auto_receive（参见SetWorkdMode），另外一种是直接作为单独对象出现，此时用户需要使用Recv成员函数自己处理数据的接收。-CUdpSocket is to simplify this, the analytical data reported by the UDP with a base class. This type of packaging based SOCK_DGRAM the most basic operation. This provides two types of work, is a practical and UDP data processing function of tight coupling, it needs to achieve through inheritance, as set workmode auto_receive (see SetWorkdMode), the other is directly emerging as a separate object, users need to use this member function since Recv others receiving data processing.

本程序使用Visual C++6.0编写，使用了MFC，数据库用的是SQL Server，要正常运行本程序，请安装该数据库，并参加压缩文件中的DBConfig.ini文件。可以监控局域网内所有主机（IP）的上网情况，包括上传下载流量、浏览的网页、上网时长等-This procedure using Visual C++ 6.0 preparation, the use of the MFC, the database used is SQL Server, to the normal operation of this program, please install the database, and participated in the compressed file DBConfig.ini file. LAN can monitor all hosts (IP) access to the Internet, including uploading and downloading traffic, browsing web pages, Internet time and long

使用Global.asax定时扫描指定ip地址，并写入数据库-Use Global.asax regularly scan the specified ip address and write the database

取得主机名称与各项网络服务的程序代码-To obtain the host name and the network services program code

这是一份实验报告，是关于路由器的trace的，做的时候还是有点困难，做完了收获很大，供大家参考了，-this experiment is a report on the trace router, or the time to do a bit difficult to finish a very fruitful, for your reference.
