Disable and Stop the Firewalls
Run the following commands while logged in as the root user:
/sbin/chkconfig iptables off
/sbin/chkconfig ip6tables off
/etc/init.d/iptables stop
/etc/init.d/ip6tables stop
Disable SELinux
Edit the file /etc/selinux/config:
Change the SELINUX=
line from
SELINUX=enforcing
to:
SELINUX=disabled
Normally, this change to the /etc/selinux/config would only take effect on the next reboot, but you can also disable SELinux immediately by running the following command as root:
echo 0 >/selinux/enforce
