I have no "nameserver" entries in resolv.conf. I have the following order in host.conf: order hosts,bind When I try to telnet or ftp to a IP address which has not a host name the process hangs and I have to kill it. It seems obvious that the server daemons won't work unless the IP addresses can resolve to a name, but I would like to confirm my guesses and I would also appreciate an explanation for this implementation behaviour. TIA. Zacarías - : send the line "unsubscribe linux-net" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
