[opensuse] No IPv6 privacy address in 15.0
I just discovered IPv6 privacy address are not enabled in 15.0 by default. Why is this? It's necessary to add sysctl net.ipv6.conf.eth0.use_tempaddr=2 to /etc/sysctl.conf to enable them. This is on systems using Yast to configure networks. It appears OK with network manager. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

I believe that default was changed quite some time ago, 12.x I think. I don't recall the exact reasoning, something about NFS comes to mind. -- Per Jessen, Zürich (14.8°C) http://www.cloudsuisse.com/ - your owncloud, hosted in Switzerland. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

It's only recently that I didn't have privacy addresses. I don't recall setting them on earlier versions. In fact, when I first started running IPv6 8.5 years ago, I was wondering why I had them. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

ISTR - in the beginning, ipv6 privacy addressses were off by default. Then it was made the default, good for privacy. (may be related to a Heise c't article from 2011). I think it was then reverted to no privacy, and I'm 95% certain it was NFS related. Or some other service that expects an address not to change. There might even be a bug report. -- Per Jessen, Zürich (18.0°C) http://www.dns24.ch/ - free dynamic DNS, made in Switzerland. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

I don't run NFS here anymore. However, when connecting to servers, you use the MAC based address, as it doesn't change. Privacy addresses are used only for outgoing connections. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
