Support IPv6 to IPv4 Tunneling in Debian

Ipv6 is coming… expecially after this announcement.

For now the ISP and the hardware avaible are really low but if you want, you can have a 6to4 tunnel in your linux machine.

The 6to4 tunnel is a technology to receive a ipv6 connection encapsulate in a ipv4 connection (for more info)

Right now I’m using a Debian Sid with a gogo6 connection/tunneling.

First step : Go to the site and create a new account.

For install in Debian , open your terminal :

sudo apt-get install gogoc

after that open with an editor the file

/etc/gogoc/gogoc.conf

insert yout userid and password, and change

server=anonymous.freenet6.net

to

server=broker.freenet6.net

Now change

auth_method =anonymous

to

auth_method =digetst_md5

save the file

In terminal write:

sudo /etc/init.d/gogoc start

and we goign to thest the connection with

ping6 -c4 ipv6.google.com

if you receive the ping you are on, you can also check  with ifconfig and see another interface TUN  is avaible

Another test is going to sites with ipv6  ready like ipv6.google.com , kama.net, ip6.me.

FIREFOX

On Debian  the ipv6 is disable by default, so for re-enable :

1. In the Location bar, type about:configand press Return.
   • The about:config “This might void your warranty!” warning page may appear. Click I’ll be careful, I promise!, to continue to the about:config page.
2. In the Filter field, type network.dns.disableIPv6.
3. In the list of preferences, double-click network.dns.disableIPv6 to set its value to false.
4. Now check one ipv6 site

Why all this?

1. For fun

2. To educate yourself to  new standard, so when in this year the ISP and other companies will jump on the Ipv6 train they will find you already on board.
