【求助】win7 下如何设置SOCKET才能监听所有IP包
我想监听本机上的所有数据包，查资料后设置如下，但是只能监听发出去的包不能监听收到的包，请教要如何设置。我才接触网络部分，求指点！
WSADATA wsData;
WSAStartup(MAKEWORD(2,2),&wsData);
//建立套接字
SOCKET sock;
sock=socket(AF_INET,SOCK_RAW,IPPROTO_IP);
BOOL flag=TRUE;
//设置IP头操作选项，用户可对IP头处理
setsockopt(sock,IPPROTO_IP,IP_HDRINCL,(char*)&flag,sizeof(flag));
char hostName[128];
gethostname(hostName,100);
//获取本地地址
hostent * pHostIP;
pHostIP=gethostbyname(hostName);
//填充SOCKADDR_IN结构
sockaddr_in addr_in;
addr_in.sin_addr=*(in_addr*)pHostIP->h_addr_list[0];
addr_in.sin_family=AF_INET;
addr_in.sin_port=htons(6000);
bind(sock,(PSOCKADDR)&addr_in,sizeof(addr_in));
//把socket绑定到本地网卡
DWORD dwValue=1;
//设置SOCK_RAW为SIO_RCVALL,能接收所有IP包
#define IO_RCVALL _WSAIOW(IOC_VENDOR,1)
DWORD dwBufferLen[10];
DWORD dwBufferInLen=1;
DWORD dwBytesReturned=0;
WSAIoctl(sock,IO_RCVALL,&dwBufferInLen,sizeof(dwBufferInLen),&dwBufferLen,sizeof(dwBufferLen),&dwBytesReturned,NULL,NULL);
