In win7, my computer can automatically get a IPV6 global address and use ipv6 network, but in ubuntu natty, I can't find out how to let stateless configuration work. My network is a university campus network,so I don't need tunnels. I think if one thingg can silently and successfully complished in windows it shouldn't be impossible in linux.

I did can manually edit /etc/network/interfaces and use a static ipv6 address, and I can use ipv6 this way, but I just want to use auto-configuration.

I found this post: How to disable autoconfiguration on IPv6 in Linux?

and try

sudo sysctl -w net.ipv6.conf.all.autoconf=1
sudo sysctl -w net.ipv6.conf.all.accept_ra=1

but no luck
