 ==== How do I disable IPv6? ====
+Edit /etc/sysconfig/network and set "NETWORKING_IPV6" to "no"\\
+For 5.4 and later, replace in /etc/modprobe.conf\\
+<code bash>
+alias ipv6 off
+</code>
+by
+<code bash>
+options ipv6 disable=1
+</code>
+== Alternative (which might be easier and works on any release with /etc/modprobe.d): ==
+<code txt>
+# touch /etc/modprobe.d/disable-ipv6.conf
+# echo "install ipv6 /bin/true" >> /etc/modprobe.d/disable-ipv6.conf
+</code>
+For CentOS 5.3 or older, add the following to /etc/modprobe.conf :
+<code bash>
+alias ipv6 off
+alias net-pf-10 off
+</code>
+Run /sbin/chkconfig ip6tables off to disable the IPv6 firewall, Reboot the system
+:!: With the 5.4 update symbol/ipv6 module dependency capabilities have been introduced; therefore, if IPv6 has been previously disabled as above an upgrade to the bonding driver in 5.4 will result in the bonding kernel module failing to load. For the module to load properly use instead:
+<code txt>
+# touch /etc/modprobe.d/disable-ipv6.conf
+# echo "options ipv6 disable=1" >> /etc/modprobe.d/disable-ipv6.conf
+</code>
+:!: Upstream employee Daniel Walsh recommends not disabling the ipv6 module but adding the following to /etc/sysctl.conf:
+<code bash>
+net.ipv6.conf.all.disable_ipv6 = 1
+</code>
+==== Package require for X Forwarding ====
+Following packages requires for minimal OS install and X Forwarding.
+<code bash>
+yum install xorg-x11-xauth xorg-x11-fonts-* xorg-x11-utils
+</code>
+==== rc.local not working ====
+Since RHEL 7, by default rc.local is disabled.\\
+:!: check permission is 755 on /etc/rc.d/rc.local
+<code bash>
+systemctl enable rc-local
+systemctl start rc-local
