[opensuse] Enable "Privacy Extensions" in 13.1
This is something I've asked about before, but yet to receive a usable answer for. I'm running 13.1 and cannot find a way to enable the IPv6 random number address, when using the ifconfig method. It does work in NetworkManager. There is the info provided here: https://en.opensuse.org/SDB:Native_IPv6#Randomly_generated_host_part_of_IPv6... However, while it worked with earlier versions, it does not work with 13.1. The specified file /etc/sysconfig/network/ifsysctl doesn't even exist in 13.1, though the man page for it does. Is there any way to enable this in 13.1, without using the NetworkManager? Or is this a new "feature"? tnx jk -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

That page says it is the default, but that is clearly not the case.
However, while it worked with earlier versions, it does not work with 13.1. The specified file /etc/sysconfig/network/ifsysctl doesn't even exist in 13.1, though the man page for it does.
Is there any way to enable this in 13.1, without using the NetworkManager?

I wouldn't expect any significant change on a reboot - amending net.ipv6.conf.all.use_tempaddr should take immediate effect.

I just made this change on my laptop, then cycled the wlan interface up/down.

I just tried shutting down the interface with ifconfig and restarting it again. No difference. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

I added that line to sysctl.conf on my firewall computer & rebooted it. Again no difference. The command doesn't work either. I still only get the MAC based address. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Weird.

The only difference is the interface, your enp0s25, my eth0 was 0. However, changing it to 2 makes no difference.
