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
alias ipv6 off
by
options ipv6 disable=1
Alternative (which might be easier and works on any release with /etc/modprobe.d):
# touch /etc/modprobe.d/disable-ipv6.conf # echo "install ipv6 /bin/true" >> /etc/modprobe.d/disable-ipv6.conf
For CentOS 5.3 or older, add the following to /etc/modprobe.conf :
alias ipv6 off alias net-pf-10 off
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:
# touch /etc/modprobe.d/disable-ipv6.conf # echo "options ipv6 disable=1" >> /etc/modprobe.d/disable-ipv6.conf
Upstream employee Daniel Walsh recommends not disabling the ipv6 module but adding the following to /etc/sysctl.conf:
net.ipv6.conf.all.disable_ipv6 = 1
