IPv6 on OS X
Friday Pete and Joe Breen put on a "Lab abd Learn" here at EBC. It was alot of fun and not only was I able to configure a Cisco router to use IPv6 I was able to get IPv6 working on my G4 (and later on my desktop) . I configured a Cisco router and got local IPv6 running as well as connectivity to a 7500 that was running native IPv6 on the backbone.

I had to do a couple things before I could configure the router. Since I have been using OS X I have not had the need to use a serial console connection to configure a router so I downloaded Zterm (the carbon version) and re-loaded the driver for the Keyspan USB<-> serial adapters (I think I have just about every one they have ever made). This was alot easier than I thought it would be. The only problem I had is I had to re-boot my laptop for Zterm to see the serial port on the adapter (I have not had to do that before).

I was able to turn on IPv6 on OS X and get the dancing turtle connected to the backbone router/switch and also directly from the Router I configured. I was also able to modify my /etc/resolv.conf so that I could use Pete's IPv6 nameserver and connect to kame directly without using a IPv4 name server and entry. I was pretty impressed at how easy it was to configure and use IPv6 on OS X. The only hang-up I had there was that I found I needed to disable my wireless adapter. Apparently Apple has not implemented automatic port detection and routing on IPv6 like they have on IPv4. Also I found that the only browser that I could get IPv6 HTTP to work on was Mozilla. IE, Safari, Netscape and Camino apparently do not support IPv6 HTTP because I could not get the dancing turtle with them.

To turn on IPv6 on OS X open up the terminal and enter:
sudo ip6config start-v6 en(x)
where (x) is your active IP interface, typical en0 for built-in ethernet or en1 for wireless. Remember that IPv6 does not work under NAT. I have been having trouble at home getting Mozilla to use IPv6 when I use my wireless on an old original Apple AirPort base. I can ping6 and traceroute6, but can't seem to get the dancing turtle.

This is the setup for a native IPv6 network that you may be attached to. Addressing, default router, etc. will be set automatically if all goes well.

If you want to use the 6to4 tunnel so you can tunnel through the IPv4 internet to the IPv6 internet just issue this command after the first one:
sudo ip6config start-stf en(x)
again where (x) is your active interface that you are using.

I could not get 6to4 to work on the UofU LAN in the business department, so I assume that they are blocking protocol number 41 which is used for 6to4 tunneling.

Over the next couple days I will add links to this post and also links to some useful IPv6 sites I have found.
