ntpdc

Hi,
In the lesson "Configuring the ntp Client" (https://trainingportal.linuxfoundation.org/learn/course/linux-system-administration-essentials-lfs207/network-addresses/network-addresses?page=10) the command ntpdc -c peers is suggested to show the time differential between the local system and configured time servers. However, I cannot find the package on Debian. But an apt search and apt info reveals the ntpstat command instead which mentions the ntpdc on the info page:

Description: show network time protocol (ntp) status
 This program uses an NTP mode 6 control message, which is the same as that
 used by the ntpq command. The ntpdc command uses NTP mode 7, details of
 which are elusive. For details on the format of NTP control message, see
 http://www.eecis.udel.edu/~mills/database/rfc/rfc1305/rfc1305b.ps.

But even after installing ntpstat, the ntpdc command is not available.

Any suggestions?

Thanks,
Urs
