I'm trying to disable Privacy Extension but unable to do it.

I wanted to disable IPv6 random temporary addresses.

I tried with and still unsuccessful

Code:
sysctl -w net.ipv6.conf.all.use_tempaddr=0


Code:
sysctl -w net.ipv6.conf.all.use_tempaddr=1

Your other addresses are neither random, temporary, nor privacy extension addresses. As you can see, they are autoconfig addresses based on your MAC address (20cf3047d17a).

If you really want to disable Privacy Extensions, why don't you just compile it out of your kernel?

I know is autoconfig via MAC address because in one site i test ipv6 say that.

First kernel by "default" is disable Privacy Extensions seeing I still generating IP Address so i choose to enable in kernel and then deactivate manually via sysctl but fail to do it.

It is easy to do. I enable this in autostart (/etc/local.d/privacy_ivp6.start) with the command:
Code:
echo 2 >/proc/sys/net/ipv6/conf/all/use_tempaddr

So, you can disable this with "echo... i think 1

The Kernelconfig says:
Code:
By default the kernel does not generate temporary addresses.
to use temporary addresses, do
echo 2 >/proc/sys/net/ipv6/conf/all/use_tempaddr
See <file:Documentation/networking/ip-sysctl.txt> for details.
