Better question: Have you looked into infrastructure as code? (IaaC) you can define everything in a Git repo and then create everything in a repeatable way.

I would turn swap off honestly. Chances are you aren’t going to have issues with 16GB.

I’d just where all red clothing and then not take a bracelet

We would get along mostly fine

My current boss is a bit of a horder and it drives me up a wall as I’m a bit OCD.

Time to get rid of things?

Is it ADHD related or is it something like demand avoidance? (I don’t know is a fair answer)

In my experience most people fall in between horder and own nothing. In the Autism population there are a few people in the extremes and they are hard to get along with.

It is very competitive right now

Anything that uses the Linux kernel

I would strongly suggest OpenWRT

https://openwrt.org/docs/guide-user/network/vlan/switch_configuration

You create an device called interface.vlanid

Something like eth0.1

https://en.wikipedia.org/wiki/IEEE_802.1Q

Vlans are simply a tag on a frame. You can set what if any tags are allowed and you can set the switch to tag untagged traffic. You can can limit Mac addresses with port security.

ARP is in a single broadcast domain which can span multiple switches.

ARP is in the broadcast domain (otherwise known as a lan)

Vlans create multiple lans

Subnets are on layer 3 not layer 2. You can easy access other devices on layer 3 by finding the right subnet on layer 2. ARP is used to resolve IP addresses into MAC addresses and vis versa.

Usually you would configure that on the switch

Yes you need vlans

Technically there would be some isolation at layer 3 but they would all still be in the same layer 2 network.

Changing the port is a total waste of time

Changing the port is just like putting a picture of a window on your door. Harden SSH properly and don’t waste time with security via obscurity

Use key based auth only and then run ssh-audit.

This applies across the industry

MySQL, VMware…

I wish Duckduckgo would add a band that would search all of Lemmy via Activitypub
