Is it a networking namespace? To access the UDP sockets you would need to use "ip netns exec $NAMESPACE chronyc".
Yes, I tried this command, but it didn't seem to work; If there are multiple namespaces, the client and server are deployed on the same host, as shown in the following figure.

If you can access the Unix socket, that shouldn't be necessary.
How do you use this?
