No, that's the wrong conclussion. The fact that the daemon doesn't log
anything doesn't mean that it hasn't checked the time in the interval. It
may have done it hundreds of times for all you know.
The stuff that does go into the ntp logfile is actually pretty spartan
when it comes to trying to determine what is happening with a particular
server, unless one is willing to do a fair bit of digging (as I noted in
my tome replying to Hylton's first post). Better would be to use the
"statistics" and "filegen" directives, but I have only got those to work
once, and I can't recall what made it work. It worked for awhile, then
stopped after a re-install of the entire OS (when I changed hard
drives). I'm sure I am still using identical directives, but I've never
seen any statistics files show up since. The resultant files were
definitely full of useful information when any problems arose connecting
with a particular server. If anyone has a working statistics/filegen
combination, I would definitely like to see the lines.


And you can not modify when ntp sees fit to check the time.
minpoll/maxpoll

If this configuration is not available, what command could I issue to
initiate an ntp time check against the internet ntp servers ie after I
have enabled the net connection?

Do not use the ntp daemon unless your connection is permanent.

ntpd -q does the same thing as ntpdate. See also my second note to John
Anderson.
