send.c放在主机上

recv.c放在虚拟机上

虚拟机的设置，选择birdge连接方式

 

编译环境是vc6.0

测试软件是wireshark

源代码

send.c //发送

#include <stdio.h>

#include <winsock2.h> #pragma comment(lib, "wsock32.lib") typedef int   int32; typedef short int16; typedef char  int8; typedef unsigned int   uint32; typedef unsigned short uint16; typedef unsigned char  uint8; typedef  unsigned char boolean; SOCKET listen_socket;     /* socket of waiting receiving data */ /* binded address */ static struct sockaddr_in srv; /* destination address of sending(send CLIENTS_NUM ports at one time) */ static struct sockaddr_in dest; /* port to listen on */ uint16 listening_port; //#define ERR_PRINT(fmt,...) int main(void) {   char snd_buf[100];   int num;   WSADATA  Ws;   //Init Windows Socket   //必须有这个WSAStartup函数，不然socket不成功   if ( WSAStartup(MAKEWORD(2,2), &Ws) != 0 )   {     printf("Init Windows Socket Failed::%d",GetLastError());     return -1;   }   listen_socket = socket(PF_INET, SOCK_DGRAM, 0);   if ( listen_socket == INVALID_SOCKET )   {     printf("Error: create socket failed %d/n",listen_socket);     return FALSE;   }       srv.sin_family = AF_INET;   //srv.sin_addr.s_addr = htonl( INADDR_ANY );  /* ANY Address 本机*/   srv.sin_addr.s_addr=inet_addr("192.168.1.121");//虚拟机的IP   srv.sin_port = htons(6000); //这里不需要绑定，不然绑定不成功，返回错误码10049 /*  if (bind( listen_socket, (struct sockaddr *)&srv, sizeof(srv)) != 0)   {     printf("Error: bind failed.

recv.c  //接收

 

#include <stdio.h>

#include <winsock2.h> #pragma comment(lib, "wsock32.lib") typedef int   int32; typedef short int16; typedef char  int8; typedef unsigned int   uint32; typedef unsigned short uint16; typedef unsigned char  uint8; typedef  unsigned char boolean; SOCKET listen_socket1;     /* socket of waiting receiving data */ SOCKET listen_socket;     /* socket of waiting receiving data */ /* binded address */ static struct sockaddr_in srv; /* destination address of sending(send CLIENTS_NUM ports at one time) */ static struct sockaddr_in clt; /* port to listen on */ uint16 listening_port; int32 len; //#define ERR_PRINT(fmt,...) int main(void) {   char recv[100];   int num;   WSADATA  Ws;   //Init Windows Socket   if ( WSAStartup(MAKEWORD(2,2), &Ws) != 0 )   {     printf("Init Windows Socket Failed::",GetLastError());     return -1;   }   listen_socket1 = socket(PF_INET, SOCK_DGRAM, 0);   if ( listen_socket1 == INVALID_SOCKET )   {     printf("Error: create socket failed/n");     return FALSE;   }       srv.sin_family = PF_INET;   srv.sin_addr.s_addr = htonl( INADDR_ANY );  /* ANY Address */   srv.sin_port = htons(6000);   if (bind( listen_socket1, (struct sockaddr *)&srv, sizeof(srv)) != 0)   {     printf("Error: bind failed.

先执行虚拟机里面的recv.c

弹出对话框，阻塞等待数据的到来

然后执行主机下的send.c程序

显示数据发送完毕

 

 

再看虚拟机里的执行窗口

 

 

wireshark显示

 

 

 

wireshark设置过滤条件

虚拟机

ip.addr==192.168.1.121

主机

ip.addr==192.168.1.121
