-Likely no longer needed:
- New sysstats variables: sys_lamport, sys_tsrounding
- See them with: ntpq -c "rv 0 ss_lamport,ss_tsrounding"
- sys_lamport counts the number of observed Lamport violations, while
- sys_tsrounding counts observed timestamp rounding events.

New ntp.conf items:
The 'noepeer' directive will disallow all ephemeral/passive peer
requests.
-The 'ippeerlimit' directive limits the number of peer associations
+The 'ippeerlimit' directive limits the number of time associations
for each IP in the designated set of addresses. This limit does not
-apply to explicitly-configured peers. A value of -1, the current
-default, means an unlimited number of peers may connect from a single
-IP. 0 means "none", etc. Ordinarily the only way multiple peers would
-come from the same IP would be if the remote side was using a proxy.
