​Hi Andy,​ 


the port 861 is open. Is there other files limit the remote host like a ACL list?


Thanks,

Shawn

Hi,

When you restarted the container on the server did you include -P and --privileged so it exposes port 861?

Thanks,
Andy

Hello:

OWAMP Version is 4.2.0-1. it is a supermicro system with centos7 running.
Error observed from /var/log/messages:
powstream[18059]: OWPControlOpen([10.244.24.6]:861): Couldn't open 'control' connection to server: Connection timed out

Note that I run the testpoint node in docker. I ran to this after a container restart. It used to run okay.
Thanks,
Shawn

Hello,

Can you confirm us which version of OWAMP you're running? And also on which platform?

On the OWAMP server refusing the test, do you see any output from owampd in /var/log/perfsonar/owamp.log or /var/log/message (or /var/log/syslog if Debian) ?

Regards,

Antoine.
