There's a host that's spam-bandwidth testing us, and I commented it out of the mesh config file, ran /usr/lib/perfsonar/bin/build_json and copied the result to /opt/perfsonar_ps/mesh/gpn.json

…

The host is still on our maddash, and pscheduler is still scheduling tests from it.  Are there other commands to run?

 

Not having a test in your mesh doesn’t prevent other meshes from testing to you or tests scheduled ad hoc or under the control of other, unrelated programs.

 

If you consider the host is genuinely hostile, the better thing to do is use the pScheduler limit system to forbid testing.  If you’re using something close to the stock limit file that ships with perfSONAR, there’s a “hackers” identifier that its IP(s) could be added to that would bring it to a stop.

It's not a deliberately hostile host, but I'd like to block it temporarily.
