Noah, Okay, I did some more checking. Just because the host resolves does *not* mean that it is actually serving the ntpd service. You can tell if it is or not (I think, since I can't find a man entry) by typing "ntpq <hostname>". When I tried that on the time.nist.gov server, I didn't get anything. Ditto when I tried ntp.tuxfamily.net. However, when I tried it against clock.redhat.com, I got a response. Try changing your ntp.conf to clock.redhat.com. Also, check that ntp is open on your iptables. Try "iptables -L". You should see a couple of lines something like: ACCEPT udp -- clock.redhat.com anywhere udp spt:ntp dpt:ntp ACCEPT udp -- clock.redhat.com anywhere udp spt:ntp dpt:ntp The ntp daemon is supposed to automatically open the iptables firewall, but you might need to restart the service (service ntpd restart) to do it.
