For example, this command checks the status of iptables when run as root:
# /sbin/chkconfig --list iptables
This is the output if iptables is disabled.
iptables 0:off 1:off 2:off 3:off 4:off 5:off 6:off
This command checks the status of SELinux when run as root:
# sestatus SELinuxstatus: disabled
One method of disabling iptables is to become root, run this command, and then reboot the system:
/sbin/chkconfig iptables off
You can disable SELinux by editing the /etc/selinux/config file. As root, change the value of the SELINUX parameter in the config file and reboot the system:
SELINUX=disabled
For information about disabling firewall software, see the documentation for the firewall or your operating system. For information about disabling SELinux, see the SELinux documentation.
