[ntp:questions] Re: Setting maxpoll interval with 'ntpdc'

Well, while playing I found that if you use the ntpdc 'addserver'
command and place a integer in place of the 'prefer' option it uses that
as the minpoll value.  If you enter an incorrect integer it spits out
that you've used an invalid minpoll value.  I didn't see this minpoll
argument documented anywhere and haven't been successful finding a way
to edit the maxpoll.

>What problem are you trying to solve by adjusting Minpoll  and/or
Maxpoll?
I'm not the end user, so I don't have a good answer for that, expect for
saying the customer is always right :-)

What problem are you trying to solve by adjusting Minpoll  and/or
Maxpoll?

I don't believe you can, or should do this.   Ntpd selects the poll 
interval within the range specified by the default values for Minpoll 
and Maxpoll.  The defaults are correct for most circumstances.   The 
only exception that occurs to me is a dial-up connection to a server;
such servers are polled much less often than broadband connections.
