Pi-Hole debug log

I'm thinking about writing up a nice guide so let me know if that would be useful to anyone but in the meantime, some notes about difficulties I ran into setting up a pi-hole

First off, I do want to say that this is actually pretty technically complicated? Like it's been floating around tumblr for a while, lots of people have done it, you can too, but when OP on that viral post said they took 2 hours and don't know anything, I think they mean they don't know anything in the same way I do (I have a whole degree in computers I have used a terminal before, but I hadn't used a raspberry pi before)

Rest below the cut

Gathering Materials Good news: there's lots of viable options for a raspberry pi that works with pihole! The minimal requirements are really very minimal. You need some computer that you're willing to devote to blocking your internet. (Theoretically you could do this on a computer also used for different stuff but that would suck and make you have no ram.) In practice, unless you've got a spare working laptop floating around for some reason, you are going to want that to be a raspberry pi. Bad news: now you have to make decisions. The "official" pihole kit has been sold out for ages, so that's not an option. I said fuck it and bought kit for the raspberry pi 4 off of one of the licensed distributors linked from raspberrypi.com (because it had all the requirements) but that was ~$100 with shipping and there ARE cheaper options. It looks like the raspberry pi zero barely hits the RAM requirements and is $15 at a licensed distributor so that's likely as low as you can go. And if you're not just buying a kit you'll need at a minimum a power supply, a microsd card (the pihole requirement is 4GB but everything I was seeing was way bigger anyways), and a way to read a microsd card (either a USB microsd reader or if your laptop already has an sd card reader you'll need one of those microsd to normal sd card converters which idk where you get but a USB microsd reader is very cheap). You don't need but may want an hdmi cable that will connect to the pi

Setting Up and Using a Raspberry Pi You may notice for notes that aren't a guide (yet) this is going into Great Detail about the early parts of the setup. As someone who hadn't used a raspberry pi before, I found all the pihole guides I was looking at skipped the basics I needed and most of my setup time was trying to figure out what was going on with my raspberry pi, not actually doing the pi-hole thing. The raspberry pi getting started page actually had all the information I needed in conjunction with their pihole setup guide if I'd read it thoroughly enough but since I didn't a general overview: first you plug the sd card into your personal computer to image it; then once it's imaged you take it out and put it in your raspberry pi; then after it's blinked at you a bit you ssh to your raspberry pi while on the same wifi network you just set up in the imaging step. This is running your raspberry pi "headless" which means you don't need a monitor/hdmi cable but does make it harder to debug if you can't ssh. Also if you're on windows apparently you NEED to download a different terminal because windows command prompt for all that it's gotten better over time cannot connect to unix operating systems (which raspbian is).

AT&T hates internet configuration Now we're getting to the part that's specific to me. My internet is on AT&T, which has overall been pretty okay (and they've had great technicians for setup and repair), but AT&T fiber does not let you set your own DNS. The non-annoying backup is to make the pi-hole your DHCP server instead of your DNS server, which IS in every setup guide but is NOT very detailed. (Possibly if I wasn't on AT&T this whole paragraph would be complaining about the level of detail of guides about making your pi-hole your DNS.) To get DHCP working, I found a different, slightly outdated guide from someone else on AT&T fiber which was pretty useful but had some pitfalls because it is a bit out of date: https://otter-security.com/how-to/ht_post/28/

Key points for setting up a pihole as DHCP server:

Set up your pihole normally/following the raspberry pi guide for the prompts

You still need to allocate a static IP for your pihole. For AT&T, this is on the IP allocation of the Home Network tab of the advanced settings page. That static IP should be the same as whatever the IP the IPv4 one the pihole install configured.

Disable DHCP on the subnets & DHCP tab. THIS IS THE STEP THAT BREAKS YOUR INTERNET: without DHCP available only some sites will work. This will be fixed by enabling DHCP on the pi-hole

Disable IPv6 (more about this later)

Enable DHCP on the pi-hole admin page: this is just a checkbox under settings->DHCP. The router ip address should be the one listed on the back of your router/the one used to get to the advanced settings (probably already correct)

Let all devices connect to the pi-hole under Settings->DNS on the pi-hole admin page (this is the step that was outdated or possibly just different because it was wired on the guide)

Don't You Forget About Mesh More details about my particular internet setup: we extend our internet with a mesh network. This kept getting in my way as I was doing the setup because I treat them largely interchangeably but it's important to put the raspberry pi and your computer on the SAME internet to do a local ssh, where the mesh vs the router are different here. I wanted to put the raspberry pi ssh on the router not the mesh because my initial setup attempt did break the mesh, but I'm not sure that that matters? Also I don't think anything connected to the mesh is getting the pihole filtering right now? Possible fixes required are either changing the mesh DNS to the pi-hole IP or seeing if the mesh has DHCP enabled.

IPv6: Still Broken So in the DHCP setup step I disabled IPv6. I couldn't get my DHCP to be forced to the pi-hole on IPv6 and I'm not sure why. I did set up my pi-hole to be IPv6 enabled and try disabling just IPv6 DHCP on my router, but it didn't seem to be hitting the pihole. Reading a help thread on this has convinced me that my best option is to leave it disabled until such a time as I want to learn things about networking again (a class I liked but also worked very hard to get a B in)

Why is my computer sad?? So I've declared pihole "working" in that our internet isn't broken and it's blocking at least some ads from some computers... but my mac is now giving ominous no internet connection warnings.

This would be a Big Problem except that I definitely can in fact reach the internet just fine. I'm on the internet right now! I don't know why my mac is sad and I am struggling to google it because it's specifically a false warning and I'm only getting results about the real problem. My hazy guess is it's ipv6 related? I could test this by disabling pihole/re-enabling DHCP on my router while keeping ipv6 off... but not in the middle of the day on a Friday

Adguard vs Pi-Hole: A Mystery Pi-Hole is no longer new technology and in the ~12 hours that it's been set up here hasn't made a dramatic difference in my life, mostly because I already had adblockers on my laptop. You can add more blocked sites and I've been looking at finding more adlists, but one alternate option is instead of running pi-hole on your raspberry pi, you run a commercial network level adblocker called AdGuard Home. I haven't tried the AdGuard option but it might do more comprehensive blocking? On the downside, it's commercial, not open source, so I do worry about them switching to break your internet if you don't give them money...

I think it's worth clarifying: from reading the article, sounds like the onionshare website was hosted by AWS but the sharing service itself still worked for her

(on the other hand signal, which is sort of the default for secure communication, uses AWS)

Writer tries to use the internet without relying on Amazon, Facebook, Google, Microsoft, or Apple. Writer struggles. A lot. Not because she can’t stop googling things, but because Google is integrated with everything, and anything it isn’t is hooked into is partnered with at least one of the other four. 

For an example, she details the long process of figuring out how to send a large file without relying on the Google iCloud or Amazon Web Services:

My Gmail alternatives—ProtonMail and Riseup—tell me the file is too large; they tap out at 25 MB. Google Drive and Dropbox aren’t options, Dropbox because it’s hosted by Amazon’s AWS and relies on Google for sign-in. Other file-sharing sites also rely on the tech giants for web hosting services.

…O’Brien directs me first to Send.Firefox.com, an encrypted file-sharing service operated by Mozilla. But… it uses the Google Cloud, so it won’t load. O’Brien then sends me to Share.Riseup.net, a file-sharing service from the same radical tech collective that is hosting my personal email, but it only works for files up to 50 MB.

O’Brien’s last suggestion is Onionshare, a tool for sharing files privately via the “dark web,” i.e. the part of the web that’s not crawled by Google and requires the Tor browser to get to. I know this one actually. My friend Micah Lee, a technologist for the Intercept, made it. Unfortunately, when I go to Onionshare.org to download it, the website won’t load. 

“Hah, yes,” emails Micah when I ask about it. “Right now it’s hosted by AWS.”

The troubling implications of tech monopolies on our private data are discussed, as well as potential solutions that don’t sound very appealing at all:

An uncomfortable idea I keep coming up against this week is that, if we want to get away from monopolies and surveillance economies, we might need to rethink the assumption that everything on the internet should be free.

So when I try to create a fourth folder in ProtonMail to organize my email and it tells me that I need to upgrade from a free to a premium account to do so, I decide to fork over 48 euros (about $50) for the year. In return, I get a 5 GB email account that doesn’t have its contents scanned and monetized.

However, I’m well aware that not everyone has $50 dollars to spare for something that they can easily get for “free,” so if that’s the way things go, the rich will have privacy online and the poor (and most vulnerable) will have their data exploited.

Artist note: I’m so proud of this :))) I know it’s a lot of dialogue and reading, but dialogue is grueling work for me. I’m glad with the art and for the amount of pages I made in such a relatively short time span -w- page 5 was super fun to work on. A lot of blood, sweat, and hours here... :) The backgrounds were a big bore tbh, but I finished them! Yippie!

100% have been perusing your climate change masterpost, and understand you're probably swamped so feel free to delete of course. But if you can find the time, is there any kind of hope to give in fighting climate change now? Can we save ourselves against the oncoming steamroll?

You hang in there too. Thanks for finding the hope among everything else. It feels so bad rn but I have to believe it can change. I hope it can.

Yeah actually I do think there is hope.

Things are going to get rough. Things are going to get worse before they get better, both for the climate and for people living in the US (and for people living in lots and lots of other countries that will be affected by the US election results/the ways the climate will worsen as aa result).

I haven't posted about this yet because I didn't want it to come to this, but now that it has, here's something that people have been quietly saying/research has been showing for months:

-via Reuters, November 6, 2024

Renewables, especially solar, are just too powerful to be stopped. They just too much cheaper and too much better, and that's only going to become more true, not less.

Also, I think (and hope) it's actually inevitable that at some point, we'll get to net negative carbon emissions. I think it's like solar: the technology, cost, and planet all make it feel like an inevitable technological trajectory, the same way solar tech is on an exponential trajectory. (IF WE WORK FOR IT, OBVIOUSLY, but also so, so many people ARE working for it, have dedicated their lives to working for it)

I sure fucking hope that's the case, anyway.

(You can find my masterpost on going net negative on what that actually means here)

It is gonna happen more slowly and shittily than I hoped, but I do think it's going to happen.

And if we can get to net negative emissions in time to save ourselves (which I think we will, the rates of advancement in many of these areas are very impressive), then we'll be able to slowly start to undo and heal lot of the damage.
