Wiping a terminated server

To wipe a now unused server, turn the server off, booting into the SSD (Ubuntu, username and password gigatux) and then

• dd if=/dev/zero of=/dev/sda bs=1M

To get an idea of how far along it is, in another terminal, run

• kill -USR1 <PID of the dd process>

This displays the current progress, not a continually updated one, so it needs to be run again to get the status next time.
