According to the Arch wiki [0] also: # Enable IPv6 Privacy Extensions net.ipv6.conf.all.use_tempaddr = 2 net.ipv6.conf.default.use_tempaddr = 2 net.ipv6.conf.<nic0>.use_tempaddr = 2 ... net.ipv6.conf.<nicN>.use_tempaddr = 2 [0] - https://wiki.archlinux.org/index.php/IPv6 -- staticsafe O< ascii ribbon campaign - stop html mail - www.asciiribbon.org Please don't top post - http://goo.gl/YrmAb -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
