Unreal 3.2 IPv6 in OpenBSD

Hello developers and everyone else!

First let me say thanks for such a good IRCD.
And then let us continue on to my problem:

I'm running OpenBSD 4.0 with Unreal 3.2 FINAL in a small IRC-Network called NOXNet. We've got 6 servers linked, 2 with IPv6, one FreeBSD and one Debian.

Now I'm trying to set up IPv6 on my OpenBSD server, and its giving me a little hassle.

I've read the FAQ and the forum, and found some possible solutions, but none of them worked.

My IPv6 tunnel is working fine, and my Unreal links without problems without the IPv6.

Leaf-config:

Code: Select all

link       hub.noxnet.org
{
        username                     *;
        hostname                     ::ffff:xxx.xxx.xxx.xxx;
        bind-ip                      *;
        port                      7002;
        hub                          *;
        password-connect      "none";
        password-receive      "none";
        class                  servers;
                        options {
                        ssl;
                        zip;
                        autoconnect;
                };
};

And the hub-config is not that important, since its linking with other IPv6 servers.

And the error message I get is:

Code: Select all

[Wed Apr 11 12:03:19 2007] - Connect to host hub.noxnet.org[::ffff:xxx.xxx.xxx.xxx] failed: Invalid argument

I've done some sysctl modifications (required kernel recompile

)
so now its set to:
net.inet6.ip6.forwarding=1
net.inet6.ip6.v6only=0

I've tried every possible solution to this problem now, and nothing seems to help.
Does anybody got a clue about what to do?
If thats so, please tell

Try ipv6_ipv4mapping (some sysctl with that text in it).

I cant seem to find anything about any *mapping* in sysctl.

And I've been googling around whole morning now, and the only info I found is that OpenBSD currently doesnt support ipv4 in ipv6 mapping at all.

Which might be a big problem...

I stand clueless about what to do.

sucks then. could very well be that it's not possible to run ipv4/ipv6 mixed on openbsd then. *deadnow*
