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
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
