You have permission then? Fine.

You're complicating matters by using ntpdc.

Just edit the server lines in ntpd.conf and restart ntpd. If you're
using iburst on the other server lines ntpd will be ready to answer
polls about 15 seconds after a warm restart.

maxpoll 4 == 16 seconds
maxpoll 5 == 32 seconds
maxpoll 6 == 64 seconds

and so on
