I tried the command and the result is:
No queue in use
Status: Disabled Debug: None
I guess the firewall has been disabled. I even tried nmap to scan for open ports. The strange thing is that even though the firewall has been disabled, almost all ports are closed except: 22, 445 and 139. Those are the original open ports in /etc/pf.inports. Even though 55555, 55556 and 41596 had been added to /etc/pf.inports, they are still reported as closed. What could be closing these ports? This is wierd.
