利用拦截者技术实现MIDAS数据安全

对程序进行了速度调用上的优化，同时删除了所有的广告，大家可以自由增加自己的广告，也不用麻烦改版权信息，只需要把bottom.asp和Head.asp的版权信息改成贵站的就可以了。-right procedures for the transfer speed of optimization, delete all the advertisements, we can add their own advertising, do not have to change copyright trouble information only and should bottom.asp Head.asp copyright information into the Guizhan on it.

VC++编程实现网络嗅探器 sniffer 的源代码-VC Programming Network Sniffer sniffers source code

共享以太网：在共享网络环境中，所有的主机都连接到同一条总线并且与其他的主机竞争带宽。这意味着在这样的环境中，发给某个主机的数据包也会被其它所有的机器收到。因此在这样的环境中，任何设置成混杂模式的主机，将可以捕获发送给其它主机的数据包，从而窃听网络上的所有通信。 -Ethernet sharing : sharing network environment, all of the hosts connected to a bus with other mainframe competition bandwidth. This means that in such an environment, to a host of data packets will be all other machines received. In such an environment, any set pattern of mixed mainframe, will be sent to the capture of other mainframe data packets, thereby tapping on the network for all communications.

本程序我花了一个月的时间做的，就是嗅探器，用处很大啊，让出来给大家-This procedure took me a month to do that sniffer, useful ah, let out to the U.S.

一个网络监控的源代码，vb语言编写，非常好，共享给大家-A network monitoring the source code, vb languages, very good, to share to everyone

一个简单既网络嗅探器 可以看到源地址和目的地址-Both a simple network sniffer can see the source address and destination address

交换环境下的网络嗅探-exchange under the Network Sniffer

  Ethernet为我们广泛使用，Ethernet设备是以48位MAC地址传输数据帧的，因此，必须有一种协议维护IP地址和物理地址之间的对应关系。一般主机都在系统中维护一张表，用来储存着两种地址之间的动态或静态映射，而ARP（Address Resolution Protocol）协议就是用来确定上述映射关系的协议。 ARP协议(Address Resolve Protocol,地址解析协议)工作在TCP/IP协议的第二层(数据链路层)，用于将IP 请点击左侧文件开始预览 ！预览只提供20%的代码片段，完整代码需下载后查看 加载中 侵权举报

一个非常简单的基于MFC单文档结构的LAN包信息监视器，仅仅 实现了非常简单的功能，留待大家进一步扩展。该应用基于NT/2000/xp下的NDIS Packet Driver,所以你在运行它之前必须添加该包驱动程序-a very simple MFC single document based on the structure of the LAN packet information monitors, only achieved a very simple function, we leave it to further expand. The application based on the NDIS NT/2000/xp Packet Driver, so you run it must be added before the packet drivers
