Памятка Отключение IPv6 в Linux


По материалам интернет сообществ:


  • Edit /etc/sysconfig/network and set "NETWORKING_IPV6" to "no"
  • 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

Alternative (which might be easier and works on any release with /etc/modprobe.d):

touch /etc/modprobe.d/disable-ipv6
echo "install ipv6 /bin/true" >> /etc/modprobe.d/disable-ipv6

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
echo "options ipv6 disable=1" >> /etc/modprobe.d/disable-ipv6
