I meant something like "systemctl status ntpd" rather than ntpq,

But there's something odd, in the Fedora install anyway: I'm seeing this:

$ ntpq
ntpq> as
ind assid status  conf reach auth condition  last_event cnt
===========================================================
  1 62962  8013   yes    no  none    reject unreachable  1

... where zappa.gregorie.lan physically the same hardware & software as
localhost

Here's the behaviour I'm seeing:

1) setting 'host' to an undefined host name
   (gets "Name or service not known" error)

2) setting it to a valid host name which is not running
   ntpd (gets "read: Connection refused" if you try to query it)

3) setting it to a valid host name with ntpd running (gets
   "***Request timed out" if you try to query it

4) setting it to 'localhost' (queries work OK).

It doesn't seem to matter whether case 3 is the same system as in case 4,
so there's evidently something amiss on the 'host' command, at least with
version ntpq 4.2.8p13@1.3847-o Thu Mar  7 14:37:11 UTC 2019 (1)
