Hi, While doing tests on IP multicast, it appears that subscribing to more than one multicast group does not work as expected: Joining a first group with setsockopt(li_socket, IPPROTO_IP, IP_ADD_MEMBERSHIP, &li_mreq, sizeof(li_mreq)); is ok, messages are received. But when joining a second group setsockopt(li_socket2, IPPROTO_IP, IP_ADD_MEMBERSHIP, &li_mreq2, sizeof(li_mreq2)); messages of first multicast group are not received anymore. Thank you for any help - : send the line "unsubscribe linux-net" in the body of a message to majordomo@vger.kernel.org
