Is it possible to change the polling interval of one or more associated
servers at runtime? It seems like I should be able to run:
ntpq -c "writevar &associd hpoll=N" or is it ppoll?
Actually, I should have been more specific and say change the minimum
polling interval. In other words, be able to adjust the conf file's
minpoll flag at runtime instead of restarting.
What problem are you trying to solve?
NTPD does a pretty good job of adjusting itself most of the time.
Short poll intervals are useful when correcting large errors.
Long poll intervals allow NTPD to make small corrections very accurately.
The idea was to bump up the minimum poll interval after ntpd has been
running for a day or so to something more kind to the remote servers
because the refclock is holding the remote servers clamped to 64
seconds. If I set minpoll in the config file, then ntpd's start up
takes a long time because of a long poll interval. If I don't set the
minpoll, then ntpd doesn't do "a pretty good job" because it clamps the
polling interval.
