hi,
i am playing with ipv6 and have some problems with firefox. ping6 and ssh are ok but with firefox i could not find a solution to connect via ipv6-network. what is the problem?
-------- $ firefox [::1] == is ok $ firefox [::1%lo] == no wget, lynx, elinks == no
$ firefox [fe80::216:cbff:fea3:7629] == no $ firefox [fe80::216:cbff:fea3:7629]%eth0 == no wget, lynx, elinks == no ----/----
www.ipv6.org http://www.youtube.com/watch?v=_y36fG2Oba0 "the day the routers died"
ping6 %eth0 and ssh %eth0 are ok:

I think I've opened bugs about mozilla mishandling IPv6 URLs five years or so ago. Maybe it's worthwhile doing this again, they are likely forgotten. Just make sure you cite the relevant RFCs. I'm not sure how much good it does to file it in our BZ, the upstream one is probably better.
# ping6 ::1 == ok # ping6 fe80::216:cbff:fea3:7629 == no
That's a link-local address. From strace I see that the interface number is not filled in to the liking of the kernel and the connect() syscall fails. Should be worth filing a bug. It might be a kernel issue but file it against ping6 for now.
# ssh fe80::216:cbff:fea3:7629%eth0 == ok # ssh fe80::216:cbff:fea3:7629 == invalid argument
Likely the same issue as for ping6.

Err. With link local addresses you MUST include the interface explicitly (either %ethX or -I eth1). Otherwise it makes no sense, the kernel has no way of knowing what interface you wanted to use, you should use global ipv6 addresses (and corresponding routing entries).
elinks http://%5Bfe80::204:23ff:fe5b:ce53%eth1%5D/ works for me btw.. Then again, rfc3986 doesn't seem to even allow that syntax, so it working is probably even a "bug" and firefox etc. are right.
