Are there known problems with src address selection with IPv6 on 2.2.19?
(I am reluctant to upgrade this box to 2.4 until Debian Woody ships..)
Using lukemftp, this is what I see:

Both routes were learnt from rtadvd from my gateway box. Since I have a
2001:401: address, I believe that it should pick that source address. For
whatever reasons, crc.ca does not have a 6to4 gate.
I also can't remove the 2002: address:
cassidy:/home/mcr# ip -f inet6 addr del 2002:c08b:2e21:2:260:97ff:fe04:3d70 dev
eth0
RTNETLINK answers: Cannot assign requested address
(ifconfig gives even less traction)
