Disable Linux Firewall

To disable the firewall for Linux, under system-> Administration-> firewall and SELinux, select the disable of firewall and check again. However, it is still enable.

1) take effect after restart:

Enable: chkconfig iptables on

Close: chkconfig iptables off

2) It takes effect immediately and becomes invalid after restart:

Enable: Service iptables start

Disable: Service iptables stop

Or:

/Etc/init. d/iptables status will get a series of information, indicating that the firewall is on.

/Etc/rc. d/init. d/iptables stop disable Firewall

Or:

To disable firewall next time, you must delete/etc/sysconfig/iptables.

But it is useless.

Finally:

Enter setup under the root user to enter a graphical interface, select firewall configuration, enter the next interface, select security level as disabled, and save. Restart.
