  • How I fixed my AD troubles

    So I run Active Directory at home off of my Synology. Some may say that running it in a home environment is overkill and normally I'd agree. But I reinstall Windows often enough that having to change all my settings every time using local GPO is annoying. So after reinstalling Windows and domain joining, all my settings were there.


    So for context, I had Pi-hole running on 10.10.10.2 and 10.10.10.3 and AD was on 10.10.10.5. So I had to set my DNS on any computer I wanted to domain join to 10.10.10.5, because the default of 10.10.10.2 had no idea the domains needed for it to work existed. However, I told it to forward all DNS traffic that wasn't related to AD to 10.10.10.2, so basically just right to the Pi-hole. This is no problem, except you lose DHCP names. So, every request appears to be coming from 10.10.10.5 even if they're from different computers. Not a big deal until I started domain joining more of them to my network. Secondly, it was a real pain for the laptops. I would normally just connect it to my main wifi network and then change the DNS manually. But if I go to a coffee shop for example, the DNS is still set to 10.10.10.5, and since it's local the coffee shop has no idea. So how did I fix it?


    AdGuard Home.


    This is a much, much better solution than Pi-hole. It blocks ads just like Pi-hole, and also had DNS rewriting which was a requirement for me. However, one feature that it has is that it can provide granular control per client. For instance, I could block TikTok on a specific device or tell it to use a specific DNS server for a client. So, I changed all of the DNS back to 10.10.10.2 so all of the traffic was going through AdGuard. I then added the domain joined computers and told them to use DNS servers in this configuration.

    Code
    [/*.telesphoreo.me/]10.10.10.5
https://dns10.quad9.net/dns-query
https://dns.google/dns-query
https://dns.cloudflare.com/dns-query

    Basically, this forwards any requests from telesphoreo.me (or subdomains) to 10.10.10.5. This lets it use the DNS for AD it needs to, and any actual stuff on telesphoreo.me will just get routed to 9.9.9.9 or 1.1.1.1. For every other domain though, it will just use one of the other DNS providers in the list.


    This way, it can access AD DNS but it goes through AdGuard first and the client information is preserved.


    I know no one here really cares, but I spent hours trying to get DHCP to work on my Synology to no avail so this is a much simpler solution


    Edit: Also, it would have indeed been possible to tell my Pi-hole to use 10.10.10.5 as the DNS server and then on my Synology forward it to an actual upstream provider, but this would have just introduced another point of failure for the entire network. At least now, if something goes wrong with my NAS, only domain join computers will be affected and the rest of the network can run fine.

  • Thoughts on ChatGPT

    Here are my thoughts:

    - For mental health advice, it's honestly not that bad. It certainly can point you in the right direction for tough situations, but probably won't be as in depth or understanding as a real therapist. It certainly could help if you cannot see a therapist for whatever reason and you're stuck on your own though.

    - It is wrong sometimes. For example, I asked it "how do you bounce an email on a mac" and it gave completely wrong instructions. What it told me sounded correct, but the option just didn't exist. It's almost like it's guessing where it would be and confidently saying that's where it is. Apple actually removed the ability to bounce emails after OS X Snow Leopard

    - It's finnicky about what you ask it sometimes. I asked it "what are some good pickup lines" and it said using pickup lines is wrong and manipulative. Phrase it differently and it will actually give you some. I thought that was interesting since I would say calling it straight up manipulative is a bit harsh. It's not like I'm asking for a how to tutorial on how to gaslight people (if you actually ask it that, it won't show you how)

  • Cloning Raspberry Pi install to another

    So I have a quick question. Back in late 2020, I bought a 8GB Raspberry Pi 4 Model B with a 64GB microSD card slot... to run Pi-hole. The answer is yes, that absolutely was overkill. I've recently ordered a the same model but this one has 2GB of RAM and a 32GB microSD card. I'm wondering if it's possible for me to clone the 64GB one to the 32GB one and just wipe the 64GB one and have the 32GB one boot up with no issues. Or would there be some sort of manual changes I'd have to make. Currently it's running Ubuntu Server 22.04 (headless) if that changes anything. And also if that is possible does anyone know what tool would let me clone the SD card easily? I'll likely be doing it on a Mac, but I can do it on Windows if that's easier. Thanks
