Installed ntpd and everything works fine except 

ntpdc -p localhost

I get

localhost: timed out, nothing received
***Request timed out

I check by issuing

systemctl status ntp

output shows, that the ntpd is running.

Could you show how to solve the problem?

Reset to default

Support for mode 7 NTP packets used by ntpdc is no longer enabled by default; from the official ntpdc documentation:

ntpdc is deprecated - please use ntpq now, as it uses a more sane interface and can provide all of the information that ntpdc used to provide.

If you must use ntpdc you have to enable mode 7 packets in your ntp.conf. See the Command Index:

enable mode7

Be aware that the official documentation says that the flag mode7

Enables processing of NTP mode 7 implementation-specific requests which are used by the deprecated ntpdc program. The default for this flag is disable. This flag is excluded from runtime configuration using ntpq. The ntpq program provides the same capabilities as ntpdc using standard mode 6 requests.

All the NTP documentation can be accessed through the NTP Public Services Project web page.
