ntp: restrict NTP mode 6 queries
The current NTP server responds to mode 6 queries from any clients.
Devices that respond to these queries have the potential to be used in
NTP amplification attacks. An unauthenticated, remote attacker could
potentially exploit this, via a specially crafted mode 6 query, to cause
a reflected denial of service condition.
See: https://www.tenable.com/plugins/nessus/97861
https://scan.shadowserver.org/ntpversion/
Update ntp.conf to restrict NTP mode 6 queries.
