Disabling IPv6

Disabling IPv6

1. Edit the file /etc/sysconfig/network by performing the following:

vi /etc/sysconfig/network

NETWORKING_IPV6=yes

change to:

NETWORKING_IPV6=no

2. Next we need to turn off ipv6 in the kernel stack. We do this by editing the following file: /etc/modprobe.conf as indicated below:

vi /etc/modprobe.conf

Insert the following lines to the bottom of the file if they do not already exist:

alias net-pf-10 off

alias ipv6 off

FOR Fedora Core 7:

blacklist net-pf-10

3. Now we need to stop and disable the ip6tables service. Do so by performing the following in a terminal window:

service ip6tables stop

Now we need to disable ip6tables from restarting in the future.

/sbin/chkconfig ip6tables off

4. After making these changes a system reboot will be required
