It first tries to use the step tickers listed in /etc/ntp/step-tickers. If it cannot use them then it falls back to use the servers listed in /etc/ntp.conf. On my system that means it does use ntp.conf since step-tickers is empty and always has been.
Yes, my step-tickers was empty, though I mistakenly reported it as not being empty, and I also have a ntpservers file in the /etc/ntp directory. It had two redhat servers listed. Not sure why, from the install probable. I set the ntpservers and step-tickers to list the same servers as in my /etc/ntp.conf file.
If ntpd sees the time as too far off it will refuse to continue trying and that is not a good thing IMHO.
Yes, that does seem counter productive.
The easiest way I have found is to simply do a service ntpd stop followed by a service ntpd start which takes care of running ntpdate to get any existing major time discrepancies adjusted, then runs ntpd to fine tune it and keep it accurate.
But that was not working. If i stoped ntpd, and ran ntpdate with a server it showed the wrong time as well. Really strange. Then I noticed that ntpq -p is listing servers that are not in my config files. Also my /var/lib/ntp/drift was always 0.00 Since changing the ntpservers and step-tickers to have the same servers as my ntp.conf file (about 6 hours ago) the time seems to be working correctly, though ntpq -p still lists strange servers.
