[opensuse-factory] IPv6 Privacy Extensions
For opensuse 13.1, I used NetworkManager so that I could turn on privacy extensions (provides a somewhat random temporary IPv6 address). With opensuse 13.2 (using wicked), this has been automatic. I did not have to do anything. Similarly, with Tumbleweed, this has been automatic. But now, since recent updates, it is not working anymore. I am not getting that temporary address. (a) What changed? (b) What magic incantation is needed to get it working again?

I experienced similar with 13.1. It worked with earlier versions, but not now. Per Jensen provided a fix. I added the following to my /etc/init.d/afterlocal file: ifdown eth0 sysctl -w net.ipv6.conf.eth0.use_tempaddr=2 ifup eth0 I'm not sure if this issue is a bug or "feature". ;-) -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org

I have pretty much decided to consider it a bug. Reported as: https://bugzilla.opensuse.org/show_bug.cgi?id=928459 I found a workaround (or "magic incantation"). I listed that in the bug report. Feel free to add your experience to that report. -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org

Hehe, hardly a fix - IPv6 privacy extensions have been enabled by default since around 12.x, see e.g. bug#678066. -- Per Jessen, Zürich (14.8°C) http://www.dns24.ch/ - free dynamic DNS, made in Switzerland. -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org

Yes, I know they've been around for a while. Our point is they're now failing and requiring a work around. -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org

Well, the default works just fine on my systems and I suspect it does (initially) on yours too. I think maybe the default is being overridden or fiddled with by something else, maybe by Network Manager. (which I don't use).

Do you have, by chance, "IP-Forwarding" enabled (YaST, Network config)? "use_tempaddr=2" is ignored when forwarding is enabled. - Yamaban. -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org

No. This is a desktop system that's not configured as a router. -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org

I'm not saying that to call you stupid or ignorant, it's just the fact that more and more software messes with config entries out of their assumed scope. I'm checking for that with these two commands: sysctl -a --pattern 'forward' sysctl -a --pattern 'use_tempaddr' - Yamaban. -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org
