I am not enough of a geek to have a deeper understanding of network topoogy, but I would think that an discussion about this would be very helpful.
I wonder, is it worth setting up a Pi hole, when talking about networking in general.
From my experience a good mantained "dnsmasq" blocking list, will do most of the job for one computer, I am not sure about a network in whole.
Also, yesterday and the day before yesterday, I was cleaning up two tower pcs from a friend of mine which are not used anymore and which I gladly took in my hands. These are, kinda or kind of, old machines with dual-core processors ranging from 2,3 GHz to 2.8 GHz. One does not include any storage but is fully working besides that. The other one has two harddrives on which one hosts Windows and the other is empty and could be used to run a Linux system.
Anyhow. I am looking for real use cases of this machines. I was thinking about a replacement desktop pc for my mother. Or a network storage server, but I have not checked yet, if the hardware supports more modern hard drives. And those both PCs are only 32 bit systems with kinda low RAM.
So, does anyone have a clue about the further usage of this computers?
