Cut and paste error? They should all look more like:

Yes, that is exactly what it looks like before Mozilla Compose
mutilated them
in producing "plain text."

Those domains all resolve, here. But I don't think you're doing
yourself any favours by referring to a bunch of NTP servers at the
same
location. You want a collection of different servers, else you might
believe a set of servers to be true, that believe themselves to
all be
true, when they're not (they might all be referencing themselves).

Originally I had three different sources within a few hundred miles in
hope of minimizing delays, some went away over time and the two left
always
worked well enough for my purposes. Your suggestion is obviously
valid. But I still can't see what's happening, since ntpq doesn't
work even when I
reduce the list to just the Redhat server.

I picked a collection that come from different locations:

server 0.pool.ntp.org iburst
server 1.pool.ntp.org iburst
server 2.pool.ntp.org iburst

Plus a couple of more local ones, to me (au.pool.ntp.org and my
ISP's)

I can do something similar but first need to fix my problem.

Any hints/errors in /var/log/ntp?

I haven't found any such log, locate *log*ntp* produces nothing I
recognize as useful?

I did find: /usr/bin/ntpstat
synchronised to NTP server (198.82.1.203) at stratum 3
time correct to within 79 ms
polling server every 512 s

Which seems to indicate ntp is working at least but I don't have the
convenient data display I am accustomed to.


Why not try using ntpq in interactive mode. Use -i to get to that
state. Then raise the debug level with "debug more" and try "peers".

Ed

This is what I got ;

ntpq -i
Name or service not known
ntpq> debug more
debug level set to 1
ntpq> peers
***No host open, use `host' command
ntpq> host 198.82.1.203
current host set to 198.82.1.203
ntpq> peers
198.82.1.203: timed out, nothing received
***Request timed out
ntpq> debug more
debug level set to 2
ntpq> peers
198.82.1.203: timed out, nothing received
***Request timed out
ntpq>

I'm not sure I'm using this right but it seems not matter what I try
ntpq does nothing
and it always worked in the past. At first I thought it might be due to
the round trip transit time
between here and the satellite which probably add a quarter of a
second? But it seems to me that
I've seen some long delays in the ntpq data at times although that's not
typical, normally more like
.160 [s/ms?].

I assume ntpd is running....

Anyway, instead of setting host to 198.82.1.203 set it to 127.0.0.1 and
try again.
