"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Something like:

access-list 101 permit  udp any <your_ntp_server> eq 123

Open in new window


Would work ... You could work with access-groups to let only hosts you decide access the NTP server..
