通过系统调用查看局域网内的计算机，获得局域网内的存活主机-View system calls through the computer LAN, LAN access to the survival of the mainframe

本设计的功能是填充一个TCP数据包，并发送给目的主机。 程序具体要求如下： 1) 以命令行形式运行：SendTCP、source_ip、source_port、dest_ip、dest_port，其中SendTCP是程序名，source_ip为源端IP地址，source_port为源端口号，dest_ip为目的地址，dest_port为目的端口号； 2) 其他的TCP头部参数请自行设定； 3) 数据字段为“This is my homework of network ,I am happy ！” 4) 成功发送后在屏幕上输出“Send OK” 。 -The design features are filled with a TCP packet, and send the purpose of the host. Program specific requirements are as follows: 1) to form the command line run: SendTCP, source_ip, source_port, dest_ip, dest_port, which are SendTCP program name, source_ip client IP address as the source, source_port as the source port number, dest_ip for the purpose of the address, dest_port for the purpose of port number 2) the head of other TCP parameters at your own settings 3) data fields for the This is my homework of network, I am happy! 4) successfully sent the output on the screen after the Send OK .

一个简单的工具，用来监听和分析在客户端和服务器之间通过TCP连接传送的数据-a simple tool to be used for monitoring and analysis of the client and server through TCP connection between the transmission of data

  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

北京大学网络信息安全课件,段云所教授写．在这里和大家分享.-Beijing University of network information security courseware, of the cloud was taught. Here we share.

检测是否网络连接（不论你是用-This program detect that network whether connected.

监控本地网络，捕获一段时间内以本机为源或目的地址的IP数据包，统计IP数据包的信息，列出本机到相同目的地址或同一源地址到本机且数据包协议类型相同的数据包的数量。-local network monitoring, capture for some time to the plane of the source or purpose of the IP addresses of packets, Statistics IP packet information, for this machine to the same destination address or addresses to the same source for the data packet agreement with the same type of data packets quantity.

这个是讲解如何使用ARP协议传送数据包的源代码，需要安装winpcap开发包后才可以成功运行-这 ?鍪????馊??问 ?用ARP幸?
