Thanks Bob,

I did a reboot to see if the same errors come up this time - without me
laying on any hands!

After a reboot, when running "ntpq -p", as requested . . . it says
"can't read: connection refused.
- and there's no console output.  Obviously ntpd isn't starting
automatically.  Wrong - I used the ntpd_flags="-q" as per a previous
posting . . . without me having RTFM - mea culpa!

Then I corrected this "run once and quit option" and now get no
"errors" on the console anymore and "ntpq -p" gives:

epia# ntpq -p
     remote           refid      st t when poll reach   delay   offset 
jitter
==============================================================================
*h2348.serverkom 192.53.103.108   2 u   62  128  377   63.394    9.194 
19.331
epia#

BTW, The idea of using "europe.pool.ntp.org" as the only server was
that the address itself resolves to a round robin pool of servers -
obviating the need for multiple entries.  I will of course sit
corrected.

My concern is now that ntpd doesn't seem to report that it has checked
the time with any timesource.  Any ideas how to confirm (apart from
changing the time to something wrong but only wrong by less than 1000
seconds?)

Cheers,

Owen
