According to http://archive.ntp.org/ntp4/ChangeLog-dev
mode 7 requests were disabled more than 2 years ago:
(4.2.7p230) 2011/11/01 Released by Harlan Stenn <stenn at ntp.org>
* Disable mode 7 (ntpdc) query processing in ntpd by default. ntpq is
believed to provide all functionality ntpdc did, and uses a less-
fragile protocol that's safer and easier to maintain. If you do find
some management via ntpdc is needed, you can use "enable mode7" in the
ntpd configuration.
