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...

void Task_Server(void *pdata)  {      SOCKET* s; int ei;          //存放返回值的变量 int RecvCnt=0;        //接收数据个数 uint8 RecvBuff[200];      //接收缓冲区 uint8 RecvBuffP=0; uint8 CanSUCCESS=0; struct sockaddr serveraddr,clientaddr;  //sockaddr 结构体由协议栈类型、IP和端口组成  uint32 regaddrBYTE;        serveraddr.sin_family = 0;     //协议栈类型 serveraddr.sin_addr[0] = MCU_IP[0];   //四位IP地址 serveraddr.sin_addr[1] = MCU_IP[1]; serveraddr.sin_addr[2] = MCU_IP[2]; serveraddr.sin_addr[3] = MCU_IP[3]; serveraddr.sin_port = 4000;     //服务器本地端口   s  = socket(AF_INET,SOCK_STREAM,TCP_

ARP模拟程序：本程序分为两个子程序，分别是arpsrc ,arptarget ；arpsrc用来模拟一台主机用来发送一个ARP的询问包，arptarget用来模拟接受ARP包的主机，对不同的ARP询问包进行处理。-ARP simulation program: This program is divided into two subroutines, namely arpsrc, arptarget arpsrc used to simulate a host to send an ARP inquiry packet, arptarget used to simulate the acceptance of ARP packet the host, asked whether the different ARP packet for processing.

罗列ip地址的一个应用-listed ip address an application

捕获IP数据包的小程序 支持TCP和UDP等协议。-IP packet capture program to support small TCP and UDP protocols.

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 .
