When 10.2 was installed it asked if you wanted to 'disable IPv6', which
it did successfully. In the past you had to make changes to
/etc/modprobe.conf. How does it do it ? I have been looking in the /etc
directory for a global configuration setting without success.
What do you mean without success?
I have not found the configuration setting that diabled IPv6.

There's no modprobe.conf there??
Yes there is a modprobe.conf and have the following settings,

alias sit0 ipv6
alias net-pf-10 ipv6

What does lsmod tell you?
That the IPv6 module is not loaded, as you would suspect if it is disabled.

Is the ipv6 module loaded?
No.


What are you trying
to do anyway?
To clarify, all the configuration files have IPv6 enabled (that I can
find), but I did disable IPv6 when the installation occurred. It is
disabled, I just want to know what settings are there to accomplish IPv6
disabling (what file, what setting). Hopefully this is understandable.
The control of IPv6 appears to be in /etc/sysconfig/sysctl file and the
variables are IPV6_FORWARD and IPV6_PRIVACY.


Nothing is straight here, the file /etc/modprobe.d/ipv6 is also involved

The line 'install ipv6 /bin/true' does not load the module and if it is
commented out it will load ipv6 !



This is probably not helpful to many, but the journey started with
trying to understand what the Enable/Disable Support for IPv6 did in
configuration files. What was found with help from posts is that the

Yast2 -> network devices -> card -> edit -> advanced -> IPv6
(Enable/Disable)

changes the global loading of the ipv6 kernel module for all interfaces
by either commenting out or not the line in /etc/modprobe.d/ipv6 file.
This does not seem to allow for some interfaces being ipv4/ipv6, and
some just ipv4 ( but probably not too useful ).

It was also discovered that /etc/sysconfig/sysctl has some IPV6
variables that should affect the use or not use of IPv6.

It was also pointed out by inhaler that there is a KDE variable that
affects ipv6 use (yast/system/ etc/sysconfig Editor/Desktop/KDE_USE_IPV6).

That is it !
