BTW. It looks like the random address is being generated, but it just is not
being used for outgoing connections...
$ ifconfig eth0

I'm still seeing this problem in Fedora 14. I connected to
http://test-ipv6.com/ it detects me as:
2001:470:1d:1c6:f2de:f1ff:fe05:8579
I used the command:
sudo sysctl net.ipv6.conf.all.use_tempaddr=1
Then I connected to http://test-ipv6.com/ and I am still detected as:
2001:470:1d:1c6:f2de:f1ff:fe05:8579
I then do:
sudo service NetworkManager stop
sudo ifdown eth0
sudo sysctl net.ipv6.conf.all.use_tempaddr=1
sudo service NetworkManager start
Now I connect to http://test-ipv6.com and I am still detected as:
2001:470:1d:1c6:f2de:f1ff:fe05:8579
This strikes me as a very critical security bug...
