Let's say you have data on a remote linux machine, and for what ever reason you need to format the drive.  Like for instance you decide to switch VPS hosts.

IP Version 6. Replacement for IPv4. A next generation IP protocol. IPv6 is backward compatible with and is designed to fix the shortcomings of IPv4, such as data security and maximum number of user addresses.

But it their copy of xp on it as well as some somewhat sensitive information. At first we were going to put the linux distribution of our fancy on it(this changes from day to day).

Now for the exciting part.  How I set it up.
