[Bug 1174418] Re: Privacy Extensions are set by default on Ubuntu 13.04, but no temporary address will be generate

Note:  From my comment above, you have have to click Save in the network
manager tool for the file to be created in /etc/NetworkManager/system-
connections.

A fresh install of Ubuntu 12.04 (LTS) does not have anything in this
directory by default but it does create privacy addresses automatically.

Title:
  Privacy Extensions are set by default on Ubuntu 13.04, but no
  temporary address will be generate

Status in “netbase” package in Ubuntu:
  Confirmed

Bug description:
  Description: Ubuntu 13.04
  Release: 13.04

  Privacy Extensions are set by default on Ubuntu 13.04, but no
  temporary address will be generate.

  In sysctl (by default):

  net.ipv6.conf.all.use_tempaddr = 2

  --> that means: create and prefer privacy addresses and use them over
  the normal addresses.

  If i added the same line "net.ipv6.conf.all.use_tempaddr = 2" to the
  file /etc/sysctl.conf, everythings works fine after a restart. The
  problem is, that the parameter "2" is set by default (results shown
  by: "sysctl -a"), but don't work. In Ubuntu 12.04/12.10 this problem
  don't appears.

  Thanks for reading this. I love Ubuntu :)!
