[CentOS] NTP on CentOS 3.4

Running CentOS 3.4, I enabled the ntpd service and noticed that it opens up a hole in the firewall for ntp from 127.127.1.0. I look in the ntpd initscript and see that it's reading in servers from /etc/ntp/step-tickers. However, that file is empty... /etc/ntp/ntpservers contains clock.redhat.com and clock2.redhat.com, but ntpservers isn't used *anywhere*.

This looks like a bug, but maybe I'm overlooking something stupid. I reviewed the RHEL manuals, but they only reference the GUI utilities now (grrr).

Any ideas a) where 127.127.1.0 is coming from (parsing bug?), or b) why the initscript doesn't reference /etc/ntp/ntpservers?

Thanks,
