Hello, how do you document your home lab? Whether it’s a small server or a big one with firewall and more nodes. I have a small pc with Proxmox and there I have a VM with OpnSense. After I’ve entered my VPN as a interface in OpenSense, I noticed that I slowly lose the overview with the different rules that I have built in my firewall. And I know that my setup is relatively easy in comparison to others here in this community. I want to have a quick Overview at the various VMs, like the Lxc container, Docker containers that I have in this and the IP addresses that I have assigned to them. I search for a simple an intuitiv way for beginners.
Jokes aside, I do keep some harder to remember stuff written down in a README.md in my repo, but mainly most things are undocumented
I operate on the philosophy that it is better for me to relearn things than lean on old documentation that may no longer be accurate/relevant.
The best way to implement a safe connection to my home lab today might not be the safest way tomorrow.
Old dog, new tricks, etc.
Also! Your documentation is an attackers wet dream.
NB: this philosophy doesn’t scale.
Security by obscurity, baby!
I’m gonna try this neat trick at work
I do this continually for work as well, I approach every new project assuming best practice or approach options have changed. It doesn’t matter how experienced I am in what I’m doing, I still loop back and check.
It’s such an automatic thing I don’t even think about it, but honestly not sure if it’s because of interest or because of fear of being called out for doing something wrong lol
“Shit, i hope i remeber the key words i searched for”
Guilty too. There are names on router- and switch interfaces. Servers get fixed IP from dhcp so is in the note field there too. That’s about it
