Stage 3: 6Bone-connected PC

Host Configuration:

NOTE: This document assumes you have completed the configuration steps from Stage 2 and that you have not rebooted or made any other networking changes since it.
NOTE: All steps will be performed on PC 2 only
Disconnect the crossover cable
Connect Adaptor 1 (eth0) to your network jack (DSL modem, in my case)
Log in as root
Modify the IPv4 configuration using linuxconf. Enter your own addresses and hostnames where appropriate:

Config->Networking->Client tasks->Basic Host Information:

Host name:

Config->Networking->Client tasks->Name server specification:

DNS Usage:

Default domain:

IP of name server 1:

(All other fields):

Config->Networking->Client tasks->Routing and gateways->Set Defaults:

Default gateway:

Enable routing:

NOTE: The rest of the settings must be as they were in Stage 2

Activate the changes and quit linuxconf
You must now undo the damage linuxconf has done to /etc/hosts. Add the lines you added to it in stage 2 again.
Linuxconf does not restart the network interfaces with the new parameters unfortunately. You will have to do this yourself by restarting the network service:

Try pinging an outside address. If this fails, you might have to set the default IPv4 route manually:

Create a Tunnel:

Browse to the following page: http://www.freenet6.net
From here, you can set up a tunnel to the 6Bone. Choose the links "Get your own IPv6 tunnel" and "Linux Debian GNU". Click the "Registration Form" button and fill in your IPv4 address (63.194.96.243 in this case), an arbitrary name that will be used in their DNS for your computer, and your country.
When you click "Submit", a perl script will be downloaded to your computer. Save it anywhere; you won't need it later.
The page you will see now has your IPv6 tunnel configuration. Take note of the following addresses:

Name:	Example address:	What it is:
"Your IPv6 address"	`3ffe:b00:c18:1fff:0:0:0:263`	The address of your side of the tunnel
"Freenet6 IPv6 address"	`3ffe:b00:c18:1fff:0:0:0:262`	The address of their side of the tunnel
"Freenet6 IPv4 address"	`206.123.31.102`	The IPv4 address of their tunnel server

Configure Tunnel Connection:

For the purposes of this section, the addresses will be referred to by the following "variables":

Variable:	How to determine it:	Example using addresses from above:
PREFIX	First four numbers of your IPv6 address	`3ffe:b00:c18:1fff`
SUFFIX	Last number of your IPv6 address	`263`
REMOTE	Last number of the Freenet6 IPv6 address	`262`
TUNNEL	"Freenet6 IPv4 address"	`206.123.31.102`

It can take a minute or two of pinging the remote side of the tunnel to start working. Be patient.
If you still cannot ping the remote side of the tunnel, bring the sit0 and sit1 interfaces down, restart the network service, create a new tunnel, and configure it.

Testing:

To make sure that the 6Bone and name resolution are working, we will ping a few hosts. Don't be alarmed if they don't all work; about half of the well-known 6Bone sites are down on the average!

Many of these sites are both IPv4 and IPv6 accessible and ping6 supports both protocols (but it will try IPv6 first). If you are only seeing pings coming back from IPv4 addresses, double-check your configuration with ifconfig and route.
Now use Chimera to browse to the sites you just pinged. If you like, you can use tcpdump to watch the traffic on the eth0, sit0, and sit1 interface to see what is going on.
