Welp...if it's not one thing.....

I've setup ntpd on
that VM.....when I do this:

[root at www5 ~]# ntpq -p

I seem to connect out with servers.....BUT since none of the '*'
in front of them, my time never gets updated?!

I've manually
set the correct time with the 'date' command to get it close....but it
still moves off track?  I can 'force' the update with ntpdate - but
that doesn't use the ntpd setup, so doesn't do what I need it to do.

/var/log/messages isn't saying too much (here's the startup
info):

Thought maybe it was a firewall
issue....shut it down for awhile - still have drift off from real
time....and added '123:udp' to 'other ports' in the RedHat Firewall Config
tool so that:

What am I missing?
