In my research operating ntpd on Windows and Linux, I discovered that
the default ntp.conf installed by Meinberg does not have any access
restrictions. I think it would be a good idea to add this to your file
unless you require more liberal access for your LAN, etc. This is the
default setup for my Ubuntu Linux machines.
# By default, exchange time with everybody, but don't allow configuration.
restrict -4 default kod notrap nomodify nopeer noquery
restrict -6 default kod notrap nomodify nopeer noquery
# allow unrestricted access from the localhost (so that you may monitor ntpd
# and perform on-the-fly configuration changes with ntpdc)
# Local users may interrogate the ntp server more closely.
restrict -6 ::1
(PS - If you email me and don't get a quick response, don't be concerned.
I get about 300 emails per day from alternate energy mailing lists and
such. I don't always see new messages very quickly. If you need a
reply and have not heard from me in 1 - 2 weeks, send your message again.)
