That's what I thought at first, but looking at my clients stats it
looks like roughly 2/3 of the clients are SNTP clients. If I'm not
mistaken, these clients will query the DNS, pick up one server, do
one NTP query and be done with it.
How do you tell if a client is running some SNTP package?
I'd expect a cron job running ntpdate would also do a DNS lookup and then
make a single probe.
The clients running ntpdate can largely be distinguished by their four NTP
requests sent in a short fraction of a second. The number four is a default
and is certainly used by a majority of ntpdate users.
