HowTo: Setup Darik’s Boot and Nuke (DBAN) to automatically erase storage devices via PXE boot

Tutorials
Darik's Boot and Nuke (abbreviated as DBAN) is a popular tool used by many organisations and individuals to securely erase hard-drives prior to disposal, or perhaps just to fix Windows problems ;) . It typically comprises a small 15MB ISO image that you can burn to CD or make a bootable USB stick from so you can boot up a PC on it and set about erasing all detected storage devices. When you're doing a lot of machines, however, booting a CD is tedious, especially when you accidentally scratch the disc and need to burn a new one. Using a USB stick and either misplacing it, or forgetting to remove it before erasing starts means you lose the content of the boot stick too. Wouldn't it be nice to be able…

HowTo: Fix networking not working after installing Ubuntu Desktop from a PXE-booted Live Environment

Tutorials
Scenario: You've setup a PXE server. You've setup an Ubuntu Live CD to boot over your network via PXE. Everything works well. You then decide to install a fresh Ubuntu Desktop installation from your PXE-booted environment. All goes well. The install finishes and your system reboots. When the system comes up, you discover that there's no network connections. Ethernet doesn't work, but wifi probably is working OK, or you can't get wifi working yet because you need to install a closed-source driver for it. You check the Network Manager and find that there is no automatically defined ethernet connection such as "Auto eth0". What's the go? Here's how to fix it. (more…)

HowTo: Create a Diskless workstation that boots from PXE using Ubuntu

Tutorials
Diskless booting is where a PC starts up purely from a network connection. It does not have a physical hard-drive in it to start from in the traditional manner. Why would you want to do this? Well, say for example you have a MythTV Frontend PC. For the most part, most Frontends are dedicated PC's connected to a TV or projector that are not used for any other purpose, so technically there is really no need to have a hard-drive inside one as nothing new will ever be stored (all the media is streamed from the Backend server). There's also the added bonus of less noise by not having a hard-drive installed. Another good example of using a Diskless boot environment is for performing offline virus scans of Windows based…

HowTo: Get an Ubuntu Live CD to boot off a PXE server

Tutorials
Following my article about creating your own PXE network boot server, here is the first practical use you can put it to - taking the Ubuntu Live CD and turning it into a network-bootable version! Network booting the Live CD has obvious advantages - aside from booting faster than CD (especially on a gigabit network), it is indispensable as an emergency boot medium in a workplace environment, especially for broken Windows systems, and allows for Ubuntu effortless installations on netbook PC's that don't have optical drives and saves you having to have a USB stick handy.

HowTo: Setup your own PXE Boot Server using Ubuntu Server

Tutorials
The Preboot eXecution Environment (PXE) provides a means of starting up a PC using a network adapter instead of the traditional method of hard-drive, USB flash stick, CD or floppy disk. Why would you want to boot a PC from the network? Well, it opens the door to booting diskless workstations, eg: Internet Cafe PC's, or if you regularly install tens or hundreds of PC's, you can start the installer on all those machines at once without needing to have individual boot/install media for each machine. You can even use Linux PXE for starting Microsoft Windows network installers and tools. This article is going to show you how to setup a standard Ubuntu 10.04 Lucid Lynx Server (will also work with Ubuntu 12.04 and 14.04) to respond to a PXE…
