Hi Everyone,<br><br>I've got an OpenBSD machine in Hong Kong, where I would like to completely erase the hard drives in the machine - including the operating system.<br>This will probably need to be done on some of my Ubuntu machines once they reach end of service also, so I thought I would ask if anyone has any experience with this.<br>
When I have physical access to the disks, I simply utilize DBAN, or boot up with the SystemrescueCD and dd=/dev/random to the entire disk.<br><br>There are may posts about a Unix machine still able to operate if the underlying operating system disk goes offline, but it is difficult to find out whether there are some OS tweaks I need to perform first. I am assuming one would turn swap off, but then, from thence forth I am unsure.<br>
<br>I am supposing that I might also be able to setup a disk image with DBAN, or SDD (Secure Data Disposal) on it, and set the boot loader to load that by default also.<br><br>Thanks again!<br><br>JohnM<br><br>
