First, the easy fix: if the local system's time differs from the NTP
server's time by a certain amount, ntpd will but sync the time. If I
remember right, syslog gets a message about this, so grep ntp in
/var/log/message and see what it says.
If this is the case, there's an easy way to fix this:
<stop ntpd>
ntpdate <NTP server's hostname or address>
clock -us or clock -s depending on whether your BIOS is UTC or not.
<start ntpd>
Failing that, my main technique to find out what's going on:
ntpq
as
rv <assID>
Example:
ntpq
ntpq> as
ind assID status conf reach auth condition last_event cnt
===========================================================
1 13724 96f4 yes yes none sys.peer reachable 15
ntpq> rv 13724
status=96f4 reach, conf, sel_sys.peer, 15 events, event_reach,
srcadr=198.136.155.3, srcport=123, dstadr=192.168.2.2, dstport=123,

Somewhere in the output for your rv command should be a clue as to why NTP
isn't sync'ing.
