'ntpdc -c monlist', but it is limited to 600 clients I think. If your ntp
server is a pool server, then you most likely exceed that count, which makes
'ntpdc -c monlist' not very useful.
You can also run Wayne Schlitt's scipts to analyze ntp traffic:
<http://www.schlitt.net/scripts/ntp/index.html>. ntp_clients creates a dump
file about clients querying your server, and then in turn is used by
ntp_clients_stats to generate statistics about those clients. I run my
ntp_clients_stats every five minutes. Here is the ntp_clients_stats output
for my ntp server:
