In a CMAN cluster there is a join protocol that all nodes have to go through to become a member and cluster nodes will only talk to known members. But as things currently stand if someone spoofs the IP address, port & cluster number then it will get through I'm afraid. The solution is to use a private network for cluster communications. -- patrick -- Linux-cluster@xxxxxxxxxx http://www.redhat.com/mailman/listinfo/linux-cluster -- Linux-cluster@xxxxxxxxxx http://www.redhat.com/mailman/listinfo/linux-cluster
