Public bug reported: When you put the following lines in sysctl.conf
net.ipv6.conf.all.autoconf = 0 net.ipv6.conf.all.accept_ra = 0 the expeced result is to disable IPv6 autoconfiguration at bootup, but, actually, it does nothing, because sysctl.conf network settings are applied after network has been started. So what happens: 1. Network interfaces are started by /etc/init.d/networking 1a. IPv6 uses autocnfiguratin, because it is enabled at this point 2. Sysctl.conf settings are applied by /etc/init/procps.conf I don't know if there is an easy solution, because inverting order things are called could break something else. ** Affects: netbase (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/997605 Title: Disabling IPv6 autoconfiguration in sysctl.conf doesn't affect boot process To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/netbase/+bug/997605/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
