You are attempting to set up monitoring on servers running Red Hat SELinux 7.1. You are unable to turn off the iptables firewall.

After getting a Linux robot up and running, you notice that the controller, spooler, and hdb robot probes all

have green ports in infrastructure Manager and the controller and remote hub show no errors. However, you cannot open the controller GUI or contact it through the hub-to-robot connection. Only the connection from the robot to the hub, port 48002, works using Telnet. To address this issue, what do you need to do?

A.

Run the service iptables stop command.

B.

Run the /bin/systemctl stop iptables.service command.

C.

Create the following firewall rule on the local Linux server:

ACCEPT tcp - anywhere anywhere state NEW tcp dpt:48000-48100

D.

Run the /etc/init.d/niminit start-persistent command.
