Listening to multicast on all interfaces

I have the following interfaces :

I have the following multicast code to listen :

  socket_file_descriptor_ = socket ( AF_INET, SOCK_DGRAM, IPPROTO_UDP );
  int flag_on = 1;
  if ( ( setsockopt ( socket_file_descriptor_, SOL_SOCKET, SO_REUSEADDR, &flag_on,
                        sizeof(flag_on) ) ) < 0 )
      { exit(1); }

  struct ip_mreq mc_req;
  inet_pton ( AF_INET, listen_ip_.c_str(), &(mc_req.imr_multiaddr.s_addr) ); 
  mc_req.imr_interface.s_addr = htonl(INADDR_ANY);
  if ( ( setsockopt ( socket_file_descriptor_, IPPROTO_IP, IP_ADD_MEMBERSHIP, 
                            (void*) &mc_req, sizeof(mc_req))) < 0) 
  { exit(1); } 

  {
    struct sockaddr_in mcast_Addr;
    bzero ( &mcast_Addr, sizeof(mcast_Addr) );
    mcast_Addr.sin_family = AF_INET;
    mcast_Addr.sin_addr.s_addr = htonl(INADDR_ANY);
    mcast_Addr.sin_port = htons ( listen_port_ );
    /* bind to specified port onany interface */
    if ( bind ( socket_file_descriptor_, (struct sockaddr *) &mcast_Addr, sizeof ( struct sockaddr_in ) ) < 0 )
      { exit(1); }
  }
  // then recvfrom ( socket_file_descriptor_, _dest_, _len_, 0, NULL, NULL );

But this does not seem to be returning data received on interface "eth5". Any pointers ?

What platform are you using? I'd guess a linux OS?

Are you completely sure that messages arrive on your interface (tcpdump, netcat?). Where does the expected data come from - did you develop the 'sender' code too? Does it use SO_BROADCAST option?
