Todo

• [x] Locate Raspberry Pi 4 and all the accessories needed to run it.
• [x] Follow Pi-hole tutorial and get it setup
• [x] Assign Static IP on Unifi Switch.

How to Set Up a Pi-Hole System on a Raspberry Pi: https://youtu.be/roYduABVjo8

Read through the site and code ... 👀 This feels "too good to be true" ... 💭 Like there must be a catch or lax security ... 🤷‍♂️

[nelsonic]

I'm really sick of Ads ... 😢 ⏳ just trying to research something for work and being subjected to garbage that I can't skip!

I understand that's how some content creators get paid for their work. 🙄 But they are everywhere and so distracting / time consuming.

I'm Seriously considering setting up a pi-hole on our @home network. 💭

Want to try and pick this up tonight.🤞🏼 Going to run it on a RPi 4. But if I can downgrade to a lower resource/power RPi 3 I will; later. 🤞🏼

While searching for Landry Room layouts https://github.com/dwyl/home/issues/240 I was served this obnoxious Ad:

This is getting a bit rediculous ...

I've never searched for anything remotely related to this Ad but it's taking up 1/3 of my screen ... 🤦‍♂️

High Availability Pi-Hole? https://youtu.be/IFVYe3riDRA

[nelsonic]

I have a million better things to be doing than this. 🙄 But sadly so many of the useful websites I try to visit have obnoxious Ads on them that I'm forced to block them at the network level.

Just tried to run:

git clone git@github.com:dwyl/learn-raspberry-pi.git

Got the following strange warning:

Apparently a known + recent issue: https://stackoverflow.com/questions/75830783/why-are-connections-to-github-over-ssh-throwing-an-error-warning-remote-host ... 🙄

[nelsonic]

Solution:

ssh-keygen -R github.com

Using Raspberry PI Imager (v1.7.5), flashing Raspberry Pi OS (32-bit) to a freshSanDisk Ultra MicroSDHC UHS-1 Card`:

While that is writing I'm going to head over to the "networking area" of the workshop and connect the Raspberry PI v3 B (ancient, but apparently more than adequate for Pi-hole) to the Switch and get everything ready so I can plug-in the MicroSD and get started.

RPi3B booted and is currently updating …

this might take a while so I’m going back to my desk to do something else …

[nelsonic]

I’d forgotten how slow RPi3 is … ⏳

[nelsonic]

Obvs, but is going to require more effort …

Configuring static up address on ISP router:

[nelsonic]

The ISP Router is garbage it does not allow a private DNS on the internal network. 🤦‍♂️

[nelsonic]

Starting again from scratch. ⏳

[nelsonic]

Updating … ⏳🙄

[nelsonic]

Installing …

[nelsonic]

Configured and already blocking requests to Ads! 🎉

[nelsonic]

Added more blocked lists:

[nelsonic]

quick test: visit youtube in chrome incognito

No ad.

[nelsonic]

Need a more comprehensive list ... https://github.com/Ewpratten/youtube_ad_blocklist Add: http://gh-pages.ewpratten.com/youtube_ad_blocklist/hosts.ipv4.txt

[nelsonic]

when I visit some sites I see a few of these:

But it's a lot better than an obnoxious ad. 🎉

[nelsonic]

I don't usually go looking for websites that have ads on them ... obvs ... But the random site I was viewing last week for my research https://github.com/dwyl/home/issues/240#issue-1712141703 is not clean as a whistle. No more annoying/irrelevant ads; just content. I'm happy.

[nelsonic]

Just visited BuzzFeed (notorious for ads): https://www.buzzfeed.com/kristinchirico/surprisingly-gorgeous-homes-made-from-shipping-containers didn't see a single one. 🎉

By far the biggest advantage of having a DNS server on our internal network is query caching! It makes the initial page load for the pages we visit frequently noticeably faster. 🐎

[nelsonic]

@iteles please confirm if you are seeing ads tomorrow when connected to the @home network. 👌

The Pi-hole has been working fine for the past 11 months. ✅ Recently moved it to the "closet": https://github.com/dwyl/learn-computer-networking/issues/20 It's using a Raspberry Pi 3 which is quite "old" at this point. But I haven't noticed a delay in accessing any sites. 💭

Ned a way to monitor it. 📊

Switched to the MEO network briefly to click on a product link in Google SERP (researching a workshop tool) Then checked the BBC news and see a massive ad for a combustion engine motorcycle:

Obviously Google Knows my approximate age, gender and income so they are serving me mid-life-crisis motorcycles ... 🤣 Love Ducati, and if I was going to burn non-renewable fossil fuels for thrill-seeking, Multistrada for sure! 🏍️ Switching back to home so I don't have to waste my time seeing ads for stuff I'm never gonna buy ... 🙃

Much sooner buy a silent yacht and go sailing around the world! ⛵ But they don't need to advertise ... if you can afford it, you know where to find one. 😉 Anyway ... back to work!!
