Unable to get NTP server name and/or address

[Pierre Bouffard]

Interface 'timeserver-control' allows the user to retrieve partial information about NTP on the system (e.g. NTP, CanNTP and NTPSynchronized - via bus 'org.freedesktop.timedate1', see [1]).

However, it is not possible to retrieve the NTP server name and address. This uses bus 'org.freedesktop.timesync1'.

Would it be possible to either update existing interface 'timeserver-control' - or to add a new interface?

For reference, I'm running Ubuntu Core 20.04.

Extending existing interface timeserver-control interface sounds reasonable to me.

[Paweł Stołowski (stolowski)]

Hold on, I got confused. The timeserver-control already allows reading of all properties of the timedate1 (NTP, CanNTP, NTPSynchronized etc). I don't see server name and address in the freedesktop spec. Did you mean to get server name/address from elsewhere (e.g. read access to ntp config?)

Hi Pawel,

As you pointed out, there are no issues reading from 'timedate1' (NTP, CanNTP, NTPSynchronized, etc).

Interface 'timeserver-control' doesn't allow reading of 'timesync1'.

This issue was raised for the ability to read 'ServerName', 'ServerAddress'... Basically looking to obtain the information displayed when running '$ timedatectl show-timesync --all'.
