I am using Ubuntu 14.04. And I have done the following to disable ipv6.



I have open /etc/sysctl.conf using gedit and paste the following lines at the end of sysctl.conf.



net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1
net.ipv6.conf.lo.disable_ipv6 = 1


But when I check it using following command,



$ cat /proc/sys/net/ipv6/conf/all/disable_ipv6


I am getting result as '0'( i.e still Enabled). Please help me to disable ipv6, so that I can use hadoop.



I followed instructions from this link.

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.
