recently samsung announced [ble sdk](http://developer.samsung.com/ble) for supporting their devices to communicate with smart device using bluetooth low energy protocol. however, the support is only limited to their mobile devices running with android 4.2.x (level 17). to my best knowledge, galaxy s4 is the only one comes with 4.2 which means the current main trend devices including galaxy s3, note 2 (currently latest official update is jellybean 4.1.x - level 16) won’t be able to get the support at this point. it really depends on when samsung will push out update for these old devices to make them work with latest sdk. with an assigned task, i started to exploit ble support on android. before this, i had no

QUESTION

Multicast being sent over hardware address of default gateway address instead of ethernet multicast address

Asked 2022-Mar-10 at 14:07

I have this code to send multicast messages to a group. There are no errors while running the program but when I monitor packets in Wireshark the ethernet destination of my packets are of my default gateway instead of something like 01-00-5e-xx-xx-xx

The code:


#include <stdlib.h>
#include <stdio.h>
#include <unistd.h>
#include <string.h>

#include <sys/socket.h>
#include <sys/types.h>
#include <arpa/inet.h>
#include <netdb.h>
#include <netinet/in.h>

void main(int argc, char **argv){
    int sockfd;
    struct in_addr interface;
    struct sockaddr_in group;
    char readbuf[1024];

    if((sockfd=socket(AF_INET,SOCK_DGRAM,0))<0){
        perror("socket error");
    }

    memset(&group,0,sizeof(group));
    group.sin_family=AF_INET;
    group.sin_addr.s_addr=inet_addr("244.244.244.1");
    group.sin_port=htons(5555);



    char loop=0;
    if(setsockopt(sockfd,IPPROTO_IP,IP_MULTICAST_LOOP,&loop,sizeof(loop))<0){
        perror("setsockopt error(IP_MULTICAST_LOOP)");
    }

    interface.s_addr=inet_addr("192.168.1.69");
    if(setsockopt(sockfd,IPPROTO_IP,IP_MULTICAST_IF,&interface,sizeof(interface))<0){
        perror("setsockopt error(IP_MULTICAST_IF)");
    }

    for(;;){
        fgets(readbuf,sizeof(readbuf),stdin);
        if(sendto(sockfd,readbuf,sizeof(readbuf),0,(struct sockaddr *)&group,sizeof(struct sockaddr))==-1){
            perror("sendto error");
        }
    }

}

244.244.244.1 is not a valid multicast address.

Multicast address are in the range of 224.0.0.1 - 239.255.255.255. The address you're sending to is not in that range. So the outgoing MAC address is not a multicast MAC.

Change the destination IP to be in the range of multicast IP addresses and you'll see a proper multicast MAC address.
