Project L1: Connecting a Ubuntu Linux VM through a Windows 7 gogo6 Tunnel (15 pts.)

What You Need

A Windows machine connected to a Gogo6 tunnel. sending Router Arvertisements
A Linux machine.

Windows Host Setup

On the Windows 7 host, set up a gogo6 tunnel with RA, as you did in the Hurricane Electric IPv6 Certification Project 2. Enable Routing Advertisements on the interface that goes to the Internet (in my case, the WiFi-USB)

I recommend that you complete Proj RA: Router Advertisements before this one, so you can be sure the Router Advertisements are being correctly sent.

Start the Ubuntu Linux 10.10 VM and log in. On the Ubuntu desktop, click Start, Accessories, Terminal.

From the VMware menu bar, click VMware, Settings. Set the Network adapter to "Bridged" mode, as shown below on this page.

On the Ubuntu desktop, in the Terminal window, enter these commands:

sudo dhclient ping google.com

You should see replies, starting with "64 bytes from...". If you do not, you need to fix your IPv4 VMware networking before proceeding further.

On the Ubuntu desktop, in the Terminal window, enter this command:

ifconfig

Find your Ubuntu machine's IPv4 address.

In the Windows 7 host machine, open a Command Prompt window and ping your Ubuntu machine's IPv4 address. If you do not get replies, there is something wrong with your IPv4 networking. Try these troubleshooting tips:

Turn off the Windows firewall.
Set the VMware networking to NAT, and then, on the Ubuntu desktop, in the Terminal window, execute the sudo dhclient command. Then set the VMware networking to Bridged again, and then, on the Ubuntu desktop, in the Terminal window, execute the sudo dhclient command.
Restart your Ubuntu virtual machine.

On the Windows 7 host computer, in the gogoCLIENT Utility, on the Status tab, find your Delegated Prefix. Mine is 2406:a000:f004:6d00/56, as shown below:

On the Windows 7 host computer, open a Command Prompt and execute this command:

ipconfig

You should see your interface's delegated IPv6 address, which should end in ::1. Mine was 2406:a000:f004:6d00::1, as shown below.

On the Ubuntu desktop, in the Terminal window, enter this command:

ifconfig

Your Ubuntu machine's eth0 adapter should have an IPv6 address in your delegated network, as shown below on this page.

Troubleshooting

If the IPv6 address is not assigned automatically, you can manually configure the IPv6 address and default route with these commands (replacing the address prefixes with your own delegated prefix):

ifconfig eth0 add 2406:a000:f004:6d00::5/64
ip -6 route add default via 2406:a000:f004:6d00::1

Testing IPv6 Connectivity

In the Ubuntu VM, in the Terminal Window, execute this command to test your IPv6 networking:

ping6 ipv6.google.com

You should see replies, starting with "64 bytes from...", as shown below. Press Ctrl+C to stop the pings.
