IPv6 over IPv4 tunneling - IPv6to4

IPv6 over IPv4 tunneling - IPv6to4: All were talking about IPv6 day and all the gaints were participating in IPv6 Day. Therefore I also want to feel the IPv6.

I created a tunnel with Hurricane and got an IPv6 address. However inorder to get this working we need to establish a tunnel to one of the Hurricane's Server.
My OS is Fedora 10 and I did following steps to enable IPv6 and IPv6to4 Tunnelling in my PC.

(If you also want to do, just execute following 4 lines in your Terminal as super user.

echo "NETWORKING_IPV6=yes" >> /etc/sysconfig/network
echo "IPV6_DEFAULTDEV=tun6to4">> /etc/sysconfig/network
echo "IPV6INIT=yes" >> /etc/sysconfig/network-scripts/ifcfg-eth0
echo "IPV6TO4INIT=yes">> /etc/sysconfig/network-scripts/ifcfg-eth0

In addition to that I created following script :

/etc/sysconfig/network-scripts/ifcfg-sit1

and added following content,

OOTPROTO="none"
DEVICE="sit1"
IPV6INIT=yes
IPV6TUNNELIPV4=xx.xx.xx.xx
IPV6TUNNELIPV4LOCAL=yy.yy.yy.yy
IPV6ADDR="2001:xxx:x:xxx::x/64"
ONBOOT=yes

After this the tunnel was established and everything was working fine.
