V. Firewall

- To turn off the firewall do the following as the "root" user:

  [root@dns ~]# service iptables stop
  iptables: Setting chains to policy ACCEPT: filter          [  OK  ]
  iptables: Flushing firewall rules:                         [  OK  ]
  iptables: Unloading modules:                               [  OK  ]

  [root@dns ~]# chkconfig iptables off

- Alternatively, use the GUI by doing the following:

  1. Open the "Firewall Configuration" dialog (System > Administration > Firewall).
  2. Click the "Close" button on the startup dialog and type in the "root" password if requested.
  3. On the resulting dialog, click the "Disable" button, followed by the "Apply" button on the toolbar.
  4. Click the "Yes" button on the confirmation dialog.
  5. Quit the "Firewall Configuration" dialog.

VI. SELinux

Set SELinux to "permissive" by editing the "/etc/selinux/config" file, making sure the SELINUX flag is set as follows.

  [root@dns ~]# vi /etc/selinux/config
  change SELINUX=permissive

- Once the change is complete, either restart the server or run the following command as "root".

  [root@dns ~]# setenforce Permissive
