Something is still weird... I created the following NM hook:
--- root@ultra:~# cat /etc/NetworkManager/dispatcher.d/pre-up.d/01ipv6ra #! /bin/sh echo 1 > /proc/sys/net/ipv6/conf/wlan0/accept_ra echo 1 > /proc/sys/net/ipv6/conf/eth0/accept_ra --- But, IPv6 still doesn't work, even after a few reboots... :-/ Other devices of this very same network, have IPv6 working like a charm... But Ubuntu 15.04 doesn't... Sometimes, it works, it is random... -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1455967 Title: NM disables accept_ra for an IPv6 connection, where it should enabled it!
