I'm working on an NTP infrastructure project and trying to demonstrate the
benefits of bare metal (vs VMs running the same OS)for commodity lower-stratum
servers...but am having a hard time quantifying the difference.
For example, here are two nodes in the same subnet and with the same upstream
Perhaps the fact that the DNS query would result in more than one answer made
the gethost* call behave differently from apparmor's perspective. You could
simulate the "server" behavior by trying a "pool" directive to a list
containing only one host to see if it behaves differently.

I'm working on deploying a private "pool" system that will allow any ntpd
client in my company to use a single directive for config (this is thousands of
hosts). The intent is to allow the round-robin nature of multiple A records in
DNS naturally distribute the load across several of around 10 d
wers based on location, "score",
etc. I really just can't afford to blackhole the hosts that can't reach my
resolvers on TCP53, hence the "break it into smaller chunks" aspect. 3 smaller
DNS lookups instead of 1

You can get all the useful raw data and present/use it however you like. Here's
a good reference to the available monitoring statistics:

have something like timemaster running. It manages multiple
time protocol sources (like ntp, p2p...) and rewrites configs for them as
needed.

Hi, Philippe. First, off, the following pages are very useful for understanding
security controls in detail:
https://support.ntp.org/bin/view/Support/AccessRestrictions
https://www.eecis.udel.edu/~mills/ntp/html/accopt.html
I'll try to answer the questions:
a) Generally, it looks pretty good. You
uld you do it ? Do you have any pointers to reference NTP architectures
