Is there an alternative for ntpq -c as, while using chronyd as client?

While using ntpd as client, ntpq -c as provides details about authentication of client to server using keys.

Finally found the answer after little experimenting. chronyc ntpdata will provide if the client authenticated to server. Not as verbose as ntpq -c as, but works.

One could use this command:

chronyc ntpdata | awk '/^Remote address/ || /^Authenticated/ { print; if (/^A/) print "" }'

The output might look like this:

Remote address  : (5E8231BA)
Authenticated   : No

Remote address  : (A29FC87B)
Authenticated   : No

Remote address  : (83EADCE7)
Authenticated   : No

The command line interface to the chronyd daemon is chronyc.

  • I know. But in chronyc, I cannot seem to find the same functionality as "ntpq -c as", which tells me if my client is able to authenticate to the server using keys. Mar 25, 2019 at 13:49
