RE: [chrony-users] chronyc always exits 0 without any output

The only thing I can think right now is that there’s something up with the network card or interface name. Somehow chronyc isn’t seeing that there’s a network to query. I am grasping at straws though.

Does chronyc return immediately or does it take a few seconds to return?

**********************************************************************
This is a long shot, since chrony may not work in the same way as ntp, but when I had similar issues with ntpq exiting unexpectedly, turns out I didn't have these lines

ntp 123/udp

ntp 123/tcp

in /etc/services

If you re-run chronyc unders trace, do you see it trying to open that file?

I think the idea is to have a level of indirection, using that file, so that ports don't have to be hard coded in the sources.  Seems like overkill to me.
