It looks like Diablo gives a nice improvement in the ability to run IPv6 for those that are interested. Launch an xterm (or ssh in from another machine), then run:

This will load the appropriate kernel modules (most importantly ipv6.ko), and setup the appropriate key(s) using gconftool.

I was all set to build my own custom kernel (or at least kernel module), and low an behold, Nokia made it very easy for me.

Also, take a look at /etc/init.d/osso-ipv6

Run the following command(s) to check your ipv6 config:

Show your IPv6 addresses (ifconfig is part of busybox, not IPv6 enabled in Diablo):
Show your IPv6 Neighbors (should show router if IPv6 RA is setup):
Show your IPv6 routing table:
Show your IPv6 kernel parameters:
This is working for me without any major issues. I had already set the browser to enable IPv6 using the "about:config" mozilla trick, and set network.dns.disableIPv6 (bool) to false. (It defaulted to true)

Now, busybox is not compiled in Diablo for IPv6, but it is available from some enterprising individuals over here: http://www.ist-anemone.eu/index.php/Maemo_IPv6_howto

They have not updated the howto for Diablo yet, but there is still very useful information.

I have been successful getting the web browser, and ssh to both use IPv6, and sshd will use it once it has been restarted (kill -sighup pid will do the trick). I am assuming that there is an /etc/init.d load order issue that causes sshd to load before the osso-ipv6 script loads. I'm sure that once I have had some sleep that it will come to me

Good luck getting to the Dancing Turtle (www.kame.net), or the Bouncing Google (ipv6.google.com) on your IT!

Those that have used IPv6 will know what I mean.
