brent Posted June 18, 2018 Share Posted June 18, 2018 To disable ipv6, you have to open /etc/sysctl.conf using any text editor and insert the following lines at the end: net.ipv6.conf.all.disable_ipv6 = 1 net.ipv6.conf.default.disable_ipv6 = 1 net.ipv6.conf.lo.disable_ipv6 = 1 If ipv6 is still not disabled, then the problem is that sysctl.conf is still not activated. To solve this, open a terminal(Ctrl+Alt+T) and type the command, sudo sysctl -p You will see this in the terminal: net.ipv6.conf.all.disable_ipv6 = 1 net.ipv6.conf.default.disable_ipv6 = 1 net.ipv6.conf.lo.disable_ipv6 = 1 After that, if you run: cat /proc/sys/net/ipv6/conf/all/disable_ipv6 It will report: 1 If you see 1, ipv6 has been successfully disabled.
