to disable the firewall. <strong>iptables</strong> is an admin command line tool
for IPv4 packet filtering and NAT. The <strong>service</strong> command is used
to save, stop, or start a service. “The <strong>chkconfig</strong> command is
used to update and queries runlevel information for system service. It is a
system tool for maintaining the /etc/rc*.d hierarchy. Use this tool to disable
firewall service at boot time.”</p><p><br></p><p>출처:http://it.megocollector.com/?p=663</p><p><br></p></div></p></div></p>
