模拟数据链路层的实现 采用 go back n 的方案，进行差错控制 vc6.0...

本程序只对一个IP地址进行，如果要对一段IP进行测试，简单修改程序即可。可将发送放在单独的进程 里(使用fork（）），send_icmp里做成循环，每次重新初始化struct sockaddr_in。那么对接收到的数据 进行分析的proc_icmp（）将多一道对IP报头ip->src字段的判断。-this procedure only a pair of IP addresses, IP to a test, a simple change procedures. This can be placed on a separate process (the use of fork ()), causing Lane send_icmp cycle, each re-initialization struct sockaddr_in. Then Butt received the data analysis proc_icmp () will more than one pair of IP header ip-gt; Src field judgment.

此程序能应用于网络数据之间的传输，既能发送，也能接收，已经调试成功，还算不错-this procedure could be used between network data transmission, can send, receive, debugging has been successful, quite well!

这是我辛苦编的一个JAVA程序,是关于SOCKET.简单,易懂.希望能被采用.多谢管理员过目-This is the hard part I of a Java process is on the socket. Simple. understandable. hope can be used. thank administrators read

目前，已经有不少的Sniff工具软件，如Windows环境下，最富盛名的工具是Netxray和Sniffer pro，用它们在 Windows环境下抓包来分析，非常方便。在UNIX环境下如Sniffit，Snoop，Tcpdump，Dsniff 等都是比较常见的。这里介绍一个用C语言和网络数据包和分析开发工具libpcap及winpcap实现的简易网络Sniffer。-Currently, there have been numerous Sniff software tools, such as the Windows environment, the most famous tool is the Sniffer pro Netxray and use them in the Windows environment capturing Packet analysis, very convenient. In the UNIX environment as Sniffit, Snoop, Tcpdump, such as Dsniff are relatively common. Presented here with a C language and network packet analysis and the development of tools to achieve libpcap and winpcap Simple Network Sniffer.
