Shut Your Pi-Hole

Adverts. Whilst probably being a necessary evil in a world that expects more for free, for the most part they are also intrusive, loud, garish and a waste of processing time and memory. Some places allow you to pay a subscription, to enjoy an ad free experience. Which is certainly something I do if it’s an application I use often and has usefulness to me. The less said about places that charge a subscription and still show garish ads the better. And there are some sites that have unintrusive ads that may actually be relevant to the person viewing them. They’re okay (should I ever allow ads on this site that’s the sort of route I’ll go down) but, personally, I don’t think I’ve ever bought anything that I’ve seen on a web page as (I’m just as bad with TV ads too), and I’ve never once clicked on one. So I’d rather minimise the wastefulness on my household systems, make my eyes happier and my brain less cluttered. Whilst you can use extensions for your browser, there is a network-wide solution which will cover every device entering your home network, including in-app ads on mobile devices. Say hello to Pi-Hole.

So I bought a Raspberry Pi 3

Despite my earlier article, where I mentioned my Raspberry Pi 1 was gathering dust for years, I decided to get myself a v3 version. Simple reason being this will let me use it as a machine to muck about with, as the v1 is now doing various tasks on the network. It’s not a good idea to mucking about with something that is heavily involved in your eco-system, until you’re ready to deploy it properly. Much better to have a ‘dev’ box for testing things out on. Besides, I got one of those ‘itches’ I needed to scratch. And the last time I got one of those, I ended up buying a new graphics card. So this isn’t too bad a purchase, in the grand scheme of things.

Using the Raspberry Pi as a DHCP server.

In the first tutorial, we set up the Pi with Rasbian, stuck it on the network, with a static IP and enabled SSH for remote log in. That’s all well and good, but there’s no point if it’s doing absolutely nothing. It’s time to get it performing some tasks. Here we are going to set the Pi to act as a DHCP server.

Setting up a Rasberry Pi with Rasbian

The Raspberry Pi was, and still is, a neat little device. I got one of the first of the v1 Model B boards off the production line, with the full intention of doing so much cool stuff with it. Even though, at the time, I was poor undergraduate the allure of a PC, capable of running Linux, for about £30 (more like £50 once you factor in a case, and power supply) was too great. The initial lead times for quite high, so it was a bit of a wait between purchasing and actually receiving it. And, truth be told, it essentially found life as a media server, running RasbBMC, as I imagine a lot of them did.
