The iptables rule you specified will only allow network traffic to flow to that port. It will not enable any service to hang off of that port. Secondly on the open port issue via netstat. Netstat only shows ports that are in use on the system via processes. In order to have port 4949 to be in use (i.e. LISTEN state) a process has to create the socket and bind to it. Iptables has nothing to do with that. -- Stephen Johnson <stephen.johnson@xxxxxxxxxxxx> -- To unsubscribe from this list: send the line "unsubscribe netfilter" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
