I'm trying to enable check_mk monitoring of my brand new perfsonar 4.0.2 system. In other words, I need to allow inbound connections to port 6556. My recipe for installing check_mk says to do this:

firewall-cmd --zone=public --add-port=6556/tcp --permanent

...which executed without error, but inbound access to port 6556 is still blocked.

Then I investigated and got confused. There's a firewalld process running, yet "iptables -L" shows some rules that apply to perfsonar.

So which firewall system is actually running: iptables or firewalld?
