RE: [chrony-users] Multiple interfaces is possible?

["Jahagirdar, Bhushan" <Bhushan.Jahagirdar@xxxxxxxxxx>]

Hi Miroslav,

I tried using below SOCK configuration in chrony.conf file in order to feed multiple time source data to chronyd.
refclock SOCK /var/run/chrony.ttyS1.sock
refclock SOCK /var/run/chrony.ttyS2.sock

With this the first socket becomes invalid and second remains as valid socket.
As per your mail below this is supposed to work.

So I am getting the error:
2015-10-14T13:03:56Z Could not read SOCK sample : Socket operation on non-socket

chronyd version I am using is 2.2

Thanks and Regards,

You can feed chronyd with data from multiple refclocks, but each source should have its own socket, so chronyd can filter their samples properly, compare the sources, discard falsetickers, etc. For example:

refclock SOCK /var/run/chrony/refclock.1.sock refclock SOCK /var/run/chrony/refclock.2.sock refclock SOCK /var/run/chrony/refclock.3.sock

If the sources don't agree exactly with each other, you may need to increase their assumed delay with the delay option (1 nanosecond by default), so their intervals overlap and pass the source selection.
