[Pkg-utopia-maintainers] Bug#781143: network-manager: IPv6 Duplicate Address Detection problem

Wed Mar 25 02:26:01 UTC 2015

Package: network-manager
Version: 0.9.10.0-6
Severity: normal

I have an dhcp6 router but my machine never gets an IPv6 address.  After
looking around it is clear that duplicate address detection is misfiring
and causing me problem.  For example running:

echo 0 | sudo tee /proc/sys/net/ipv6/conf/*/accept_dad

And reconnecting to the network brings up an IPv6 address.  This seems
very similar to bug #705996 in ifupdown but I'm not sure.

Here is the contents of /var/log/syslog as I join the network:
