windows下的，一个网络嗅探器的源码，有一定的借鉴价值，可以构写自己的嗅探器了-under the windows, a network sniffer the source code for a certain reference value can write their own structure with a sniffer

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.
