Where it stands for IPv6, because YouTube is still accessible from IPv4: the changes made by Google don’t affect users accesses to the platform — but reduced the amount of IPv4 addresses needed (because YouTube is actually one of the largest sites on the web).
Anyway, you should prepare to switch soon: IPv6 will definitively replace IPv4 in 2012. If you didn’t disable it via kernel and/or system configuration – somebody suggests to do so to increase internet speed – you could easily take IP addresses via Freenet6.
The Freenet6 community changed its web site recently and joined the Ning platform: I’ll speak about OpenSocial integration for blogs in a second time.
The best way I found to get IPv6 connectivity is Gateway6: you can choose to login with username and password – registering for a free account – or anonymously.
The next example shows how to do it without any registered account: the main difference is about credentials — if you don’t need routing.
You could find packages for almost any Linux distribution: here’s what to do with Ubuntu.
$ sudo apt-get install gw6c $ sudo apt-get remove --purge radvd
In old releases the gw6c package was called tspc and its configuration files had another path: radvd isn’t really useful for our purposes, so I suggest you to completely remove it.
You may configure the client as you like, but the next settings are taken directly from the official example:
$ sudo gedit /etc/gw6c/gw6c.conf userid= passwd= server=anonymous.freenet6.net auth_method=anonymous host_type=host prefixlen=64 if_prefix=eth0 dns_server= gw6_dir= auto_retry_connect=yes retry_delay=30 retry_delay_max=300 keepalive=yes keepalive_interval=30 tunnel_mode=v6udpv4 if_tunnel_v6v4=sit if_tunnel_v6udpv4=tun if_tunnel_v4v6=sit1 client_v4=auto client_v6=auto template=linux proxy_client=no broker_list=/var/lib/gw6c/tsp-broker-list.txt last_server=/var/lib/gw6c/tsp-last-server.txt always_use_same_server=no log_stderr=0 log_filename=/var/log/gw6c/gw6c.log log_rotation=yes log_rotation_size=32 log_rotation_delete=yes syslog_facility=USER
Warning: prefixlen must equals to 64 if you don’t have an account, otherwise it won’t work — host_type could be router just if you login, with a prefixlen of 48.
The if_prefix option is about your physical interface: it supports bridges too (change it accordingly). The tunnel_mode must be v6udpv4 if you’re behind a NAT. In this case you can’t make use of a proxy client.
I don’t suggest you to change if_tunnel_* options: you need at least to enable the tun interface in your kernel settings — if it’s not yet. Restart your network to finally get an IPv6 address.
$ sudo /etc/init.d/gw6c restart $ sudo /etc/init.d/networking restart
If you want to configure previous Ubuntu releases, just edit the file /etc/tsp/tsp.conf instead. That’s it: you could test your effective address pinging web sites with ping6 from a shell or connecting to the Google’s IPv6 search engine.
