Re: Another NTP Problem
Hi Todd, I had added the prefer keywords as a shotgun approach to getting it working. I removed it and all still appears to be working. I had my restrict default set to nomodify. Thanks for the response!

Re: Another NTP Problem
Thanks, Bret. I went back to double check everything and magically it had synced with a server. Not sure why but it is working now.

And unless you *really* know what you are doing, you should never use prefer to point to any server other than your LAN's local master clock anyway, and NEVER EVER prefer your local system clock--unless it happens to have a built-in Cesium atomic clock. =) Remove the prefer keywords, and restart your ntp service. Also, make sure that you don't have "restrict default ignore" in your configuration. The bright minds at Red Hat apparently think that ignoring all NTP packets is a useful thing for the service to do. If you still have trouble, post your ntp.conf and the output of "ntpq -p" so that we can help you troubleshoot further. -- "Of course I'm in shape!

IF the system is too far out, it will not sync and you will need to run ntpdate to sync to one of the time servers. Make sure the firewall (if there is one) allows the ntp traffic through. Port 123 IIRC. If you put servers in /etc/ntp/step-tickers the ntpd startup script will try to sync to them before starting ntpd eliminating any too far out of sync problems ntpq -p will give some information on the status of servers ntpd knows about.
