Why would you use a local DNS resolver instead of using a remote well-known resolver like 1.1.1.1 or 8.8.8.8 in a home networking situation? Your systems will cache DNS entries to paper over unavailability issues, and as long as you use one as your primary and the other as a secondary, there's a very low likelihood (probably < 0.0001%) that you'll ever have issues resolving DNS.

because those 3rd-party resolvers are not under your control, which is usually interesting for someone running a homelab, and lie in responses. "it's always dns" should ring a bell :)

For a homelab yes, but I figured GP was referring to a robust home network, not necessarily a homelab. "it's always dns" goes both ways as I've had local resolvers add huge amounts of latency to connection establishment.

Can someone explain what the multiple GPS receivers are for? I get using one for NTP. I guess a second for redundancy even though it is picking up the same satellites as the first. And the rest?

There are 2x Internet connections + racks - one in a house closet rack, the other in the garage.

Garage rack has a NAS that mirrors storage of the closet rack.

Garage rack has one Raspberry Pi GPS for time services.

Closet rack has two (different) Raspberry Pi GPS for time services.

Looking at it that way, if you accept the 2x Internet connections each being independant and acting as cross backups in case of ??? then it's just the second GPS on the closet rack that's "extra".

That can likely be written up as a home experiment in messing about with a different Pi setup.

It's overkill .. but often these home setups are there to keep current on new technology and different ways of doing the same thing .. in that light it's not uncommon to have multiple ways of achieving the same end just to gain knowledge on the pros | cons of different approaches.

I also have mixed feelings. I stopped home labing because of the energy costs. I now have everything I need (HomeAssistant / NAS / Router) running on an old Dell Precision laptop. Laptops make great servers because they are optimised for low power consumption + you get a free console and UPS built-in! I'm tempted by the new Alder Lake N100 mini PCs that are available on Chinese websites. But I need to wait until the…

Laptops are great servers? Hmm I beg to differ. They are very compressed, so they heat up a lot. You need low power server? Go for Atom like CPU with good case. My home server running D2550 and 2x 1TB HDD is less than 40W. PSU is cold.

Run the same load you do on your Atom on a laptop and it'll be cold as Thatcher gaze.

This is such a bad faith comment. The sun isn't causing climate change; we are. Do you disagree that humans need to minimise waste in order to fight climate change?

Using energy doesn't cause climate change. Producing energy from fossil fuels causes climate change. Humans don't need to minimise energy usage to fight climate change, instead they need to produce energy from non fossil sources. I wish we produced 10x energy that we do now but from renewable sources.

You're right, in the most meaningless sense of the word. I too wish we had 10x the energy from renewable sources, but we don't and won't for the foreseeable future. What we actually can do is get maybe 1/10 of our energy from renewable sources and then, to be sustainable, we need to use 1/10 of the energy we currently use.

Come on, let's admit it fellow HNers... Most of us are jealous/envious of this network setup and would love to have the money and time needed in order to own something similar. Extra points for powering all these from solar panels and also for all the "little" gizmos (ADB, NTP, LoRa, TinyPilot, MQTT and temp/humidity/power monitoring). @monstermunch You're living the dream :-)

I'd guess a good portion of us have been at that point in our lives but has moved on and downsized or shudders at the thought of keeping that monstrosity of a rack in service or updated :P

I wish every apartment would have at least some units of at least half-depth of rack space. Fitting anything (even a basic setup of a PaspberryPi + the PON modem + a minuscule switch + a PoE inhector) into the tiny space behind hatch where the cables from all the wall sockets end in my condo apartment is extremely hard. And I am still looking for a 5-port switch which would be manageable, support vlans, handle gigabi…

When powered adequately, the Ubiquiti Flex (USW-Flex) [1] might fit your needs. [1] https://eu.store.ui.com/eu/en/collections/unifi-switching-ut...

Looks great but I woud prefer to avoid Ubiquiti because I don't want to involve a 3-rd party cloud to manage it.

But I really appreciate your suggestion, perhaps I am going stick to it as I've seen no alternative so far and my previous experience with Ubiquiti makes me confident it will do the actual job great.

I find your comment to be at the absolute peak of sanctimony. Who are you to decide if it is necessary or not? Furthermore, why are you justified in negatively stereotyping Americans – a diverse group of individuals?

A diverse group of individuals who consume 12 MWh of power per capita, while it's around 6 or 7 MWh for modern European countries. It's not even a stereotype, just statistics. (got my data in two minutes from Wikipedia, so maybe not up-to-date)

I wonder how much of the difference is air conditioning?

I do a lot of similar stuff in my home network with a lot less equipment. I have a trunk switch that sits behind my router, Ethernet running into each of my rooms (came with the house), and small point switches that sit in front of each patch. I have 3 APs in my house. I have a UPS which connects to our router, trunk switch, and a single AP that uses PoE which is good enough if we need Wifi when the power goes down.…

> I do a lot of similar stuff in my home network with a lot less equipment. This is also my case. For Internet access, I use a router which has 4 2.5 GbE ports for the internal LAN, which was made several years ago with an Intel NUC and 4 USB Ethernet dongles, but which could be done today with a small and cheap fanless router using an "Alder Lake N" Intel N100 or N200 CPU. There are also such small routers with more…

Huh the ring topology is a really cool idea. With the right routing rules it could open up some ports on my trunk switch, though I'd need to upgrade my NICs. Great idea for whenever I decide to retire the SBC though!

It's very cool, I just don't know what I would ever do with it. And I'm not saying that means therefore I don't see why anybody else would need or want it, I would never use it though. I was thinking about running an ethernet cable or two around the house to hook up a 1gb link but I couldn't be assed in the end because wifi is good enough. It's not like I can max out my 11mb/1mb home internet. \My new laptop's wifi is a bit flaky so maybe I'll do it this year if the drivers and firmware don't come good.

Cameras and weather station are nice though.

I find this really disturbing. On the one hand this looks really nerdy and cool but then I see the immense amount of hardware that also relies on power... so much power. This is completely unnecessary but then I also see the pictures of an F150.. so yeah it makes sense. I have to categorize this as a (un)typical American person that does not care about the environment. Do like the fact that he runs a RIPE probe thoug…

In many U.S. states, their primary energy generation is nuclear. This is extremely environmentally friendly, meaning no issues with OP using a bunch of power.

We really need to stop demonising the use of energy. Energy is amazing. It is the reason we have seen to much prosperity in so little time. It's the backbone of our economies. Of medicine and the internet and EVs and well insulated homes. We should be doing everything we can to make energy cheaper, enabling more people to use more energy. Few things have been as damaging for climate activism than the war on energy. It's unnecessary and misses the point of the entire movement: saving the environment. Focus on cleaner sources of energy rather than demonising people using energy.
