请教两块网卡的RAW_SOCKET问题！

wbo811

有两块网卡（ip:eth0:192.168.0.8；eth1:192.168.0.9)
建立socket：int iSockFd = socket(AF_PACKET,SOCK_PACKET,htons(ETH_P_ALL));
怎么让iSockFd只收到192.168.0.8上的包。
我将socket 绑定到eth0上，部分源码如下：
struct sockaddr_ll my_addr;
struct ifreq ifr;
strncpy(ifr.ifr_name,"eth0",4)
ioctl(iSockFd,SIOCGIFINDEX,&ifr);
my_addr.sll_family=AF_PACKET;
my_addr.sll_protocol=htons(ETH_P_ALL);
my_addr.sll_ifindex=ifr.ifr_ifindex
我用bind(iSockFd,(struct sockaddr*)&my_addr,sizeof(struct sockaddr_ll));
但是到eth1:192.168.0.9的包还能收到，求解决方法！

the bind system call do not show any clue that the iSockFd can and will have any relationship will address 192.168.0.9

sorry ,I saw man packet and found I was wrong
  man pakcet said that
        By  default  all  packets  of the specified protocol type

      are passed to a packet socket. To only get packets  from  a         spe‐cific interface use bind(2) specifying an address in a struct
       sockaddr_ll to bind the packet socket to an  interface.    Only  the  sll_protocol and the sll_ifindex address fields are used
       for purposes of binding.


so your code is OK.is there are other sections you mot pay attention to ?
