[Giscard Wepiwe]

Hi everybody,
i have a problem while sending raw packet with raw socket under linux with a 
wlan card ( from Lucent Technology).

Here the code of the test application:

int main(int argc, char **argv) {
   int sockfd;
   struct sockaddr_ll mysocket;
   unsigned char dest_mac_addr[6] = {0x00, 0x02, 0x2d, 0x1d, 0x13, 0xfa};
   unsigned char src_mac_addr[6] = {0x00, 0x02, 0x2d, 0x20, 0x64, 0xcb};
   unsigned char buffer[1024], puffer[1024];
   int i, recv_ret;

   if ((sockfd = socket(AF_PACKET, SOCK_RAW, htons(ETH_P_ALL))) < 0 ) {
      perror("socket");
      exit(-1);
   }

   mysocket.sll_family = AF_PACKET;
   mysocket.sll_protocol = ETH_P_ALL;
   mysocket.sll_ifindex = 3;
   mysocket.sll_hatype = 1;
   mysocket.sll_halen = 8;

   while ((recv_ret = recvfrom(sockfd, puffer, 1024, 0, 0,0)) > 0) {
      /* Print out the packet */
      for ( i = 0; i < recv_ret; i++) {
         fprintf(stdout, "%02x%s", puffer[i],
            i == recv_ret - 1 ? "\n":" ");
      }

      /* Set the MAC address of the destination */
      for ( i=0; i<6; i++)
         mysocket.sll_addr[i] = dest_mac_addr[i];
      mysocket.sll_addr[6] = 0x00;
      mysocket.sll_addr[7] = 0x00;

      /* Set the destination and source mac_addresses */
      for ( i = 0; i < 6; i++) {
         buffer[i] = dest_mac_addr[i];
      }
      for (i = 6; i < 12; i++) {
         buffer[i] = src_mac_addr[i-6];
      }
      //buffer[12] = 0x08;
      //buffer[13] = 0x00;

      memcpy(buffer+12, puffer+12, recv_ret);
      if (sendto(sockfd, buffer, recv_ret, 0x00,
               (struct sockaddr *)&mysocket, sizeof(mysocket)) < 0 ) {
         perror("sendto");
         exit(-1);
      }
      fprintf(stdout, "To send\n");
      for ( i = 0; i < recv_ret; i++) {
         fprintf(stdout, "%02x%s", buffer[i],
            i == recv_ret + 13 ? "\n":" ");
      }

      fprintf(stdout, "I've sent\n");
   }
   return 0;
}

By sending i still have this message. Why ?

Thanks already for the help.
