I'm using centos 7 with firewallD on my server.
I have also installed docker on this machine and added it to a trusted zone of my firewall.
I have a container that listens on port
9081 but this port is not open on the firewall and the strange thing is that port is accessible from my home pc.
This is the output of
public (active) target: default icmp-block-inversion: no interfaces: eth0 sources: services: dhcpv6-client ssh ports: 443/tcp 80/tcp protocols: masquerade: no forward-ports: source-ports: icmp-blocks: rich rules:
I have two active zones :
here is the output of command
firewall-cmd --zone=trusted --list-all
trusted (active) target: ACCEPT icmp-block-inversion: no interfaces: docker0 sources: services: ports: 4243/tcp protocols: masquerade: no forward-ports: source-ports: icmp-blocks: rich rules:
Clearly the port
9081 is not open in any zone, but still, I can access it. why? how to close it?
