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

["Parker, Michael D." <Michael.D.Parker@xxxxxx>]

Have any of you tried setting SELinux into permissive mode?

 

Does chronyc run as root ok?  But not as a normal user?

I had an issue something like that with a different distribution of Linux, but I recall it taking longer to return - like it was timing out on something. Try temporarily disabling the firewall on the computer and see if that changes the behavior. If that works, then maybe you need to open the port in the firewall?

Is chronyd actually running?
ps auxww|grep chronyd |grep -v grep

That is very strange. Even if chronyd is not running it should start up.

"some calls" is a bit vague.
Does

give you any hints?
