nope... application normally called gethostbyname(3) to get the IP address of hostname pass to that function call... it just return IP address(es) without TTL value... once got the IP address... it creates a socket and return a filedescriptor.. that filedescriptor is used for connection with IP address it got from gethostbyname... for continous communication using the same filedescriptor and the IP address it got.. it will never call gethostbyname(3) again... normally programmers do that not to call gethostbyname again by assumption that hostname IP addresss is fixed... unless otherwise they need to call it again for a given reason... only to do it is to restart that NTPd process again... restarting wont cause a downtime and not even affected your host's clock... your only problem is that you have 2000 servers globally... way to do it is to create a script and automate it for you... otherwise... condition yourself and prepare for a long battle doing the manual way :-> fooler. _________________________________________________ Philippine Linux Users' Group (PLUG) Mailing List http://lists.linux.org.ph/mailman/listinfo/plug Searchable Archives: http://archives.free.net.ph
