Query NTPD's monlist remotely?

Question

How do I query NTPD for monlist remotely? It would be nice to be able to keep track of what's happening with the time server!

Answer 1

ntpdc should work just fine from other computers but you'll need to remove the noquery restriction for that IP address. If you have

restrict default kod noquery notrap nopeer

then you'll need to add a line like

restrict 192.168.1.55 kod notrap nopeer

to remove that noquery restriction for that IP address. If you don't have any noquery restrictions anywhere, then ntpdc -c monlist ntpserver should Just Work. Note that ntpd will ignore restricted requests, so the command will just time out if you don't have permission to query.
