Holiday Upgrade Disasters (feddit.uk)

So, just a light post, I upgraded my Pi4 last night and found the Linux firmware breaks a 32bit install.

I've been meaning to change to 64bit for months, but as it's my DMZ box for torrents, radicale, etc, then it's just finding the right time to convert an adhoc setup into my ansible scripts.

Luckily I had a SD backup from September to get it running again

So, what have you broken over the holidays?

Is there a technical advantage to using a 192 network vs a 10 network like you described? I would've thought they're just addresses, still IPv4 as well.

I tend to use hostnames where possible. Maybe that's not viable for your situation?

[–] B0rax@feddit.org 9 points 5 months ago (2 children)

No. But segregation into vlans has advantages. As this comes with new adresses anyway, might as well tidy up the adress space entirely.

In the end 10.20.20.10 feels much neater than 192.168.174.10.

But yes, you are right, technically the 192.168.xx.yy adress space works the same and has plenty of space for home use.

Ah okay, so it's kinda just for aesthetic reasons mostly? I'll take that explanation home any day 😄

[–] B0rax@feddit.org 6 points 5 months ago* (last edited 5 months ago) (1 children)

Exactly. You could say it was unnecessary, but I think we have crossed that line a long time ago.

😁 "Maaaybe"

Going back a little bit, you mentioned advantages to "segregating into vlans"?

Would you like to elaborate on some of those advantages?

[–] B0rax@feddit.org 6 points 5 months ago (1 children)

I am certainly not an expert by any stretch. But here are my reasons: Ability to isolate some “sketchy” IOT devices into an IOT only vlan, where they are not allowed to access the rest of the network, only the internet and incoming traffic from the other vlans. Having a “clean” vlan/subnet for servers and services where I can give out static IPs without worrying about collisions with client devices

Ah, nice. Very cool, very reasonable.

And you can do this all with a consumer grade router maybe? Or do you need to have like a small PC-like device running special software that acts like a router, that handles this?

[–] B0rax@feddit.org 2 points 5 months ago (1 children)

I have a Unifi router (Unifi cloud Gateway Fiber to be precise), which one you could argue is on the higher end of consumer hardware. But there are also more consumer oriented routers with that capability.

Cool, thank you so much for the info, mate!
