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

[Wilkinson, Matthew]

I recently installed an Oracle Linux 7.5 servers with Chrony 3.2. The chronyd will start up, read the config, and synchronize just fine (according to the syslogs).

However, when I run chronyc, no matter what options I give it (even -d) and even if I give it no options, it just exits with return 0 and no output.

Anyone run into this before or know of a way I can find out why it's doing this? I've ran an strace on it, and it just quickly runs through some calls and exits 0.

Thanks,

Matthew Wilkinson

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
chronyc -d

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.

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.

Yeah, it's very, very weird.

- chronyd is indeed running. I see the process and systemd sees it running.
- i'll try to get the strace off of it, but it's isolated
- chronyc -d doesn't do anything it just exits 0

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?

I recently installed an Oracle Linux 7.5 servers with Chrony 3.2. The
chronyd will start up, read the config, and synchronize just fine (according to the syslogs).

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

Post by Wilkinson, Matthew
However, when I run chronyc, no matter what options I give it (even
-d) and even if I give it no options, it just exits with return 0 and no output.

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

Post by Wilkinson, Matthew
Anyone run into this before or know of a way I can find out why it’s
doing this? I’ve ran an strace on it, and it just quickly runs through some calls and exits 0.

"some calls" is a bit vague.
Does
chronyc -d
give you any hints?

Have any of you tried setting SELinux into permissive mode?

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

should have thought of that. I didn’t see any logs about it, but sure enough, I rebooted the server into permissive mode and did an autorelabel and chronyc works now.

Interestingly enough, I tried to run sealert to see if I could find any errors and it throws an error itself:

policydb version 31 does not match my version range 15-30

So something is up with SELinux policy in OL 7.5...
