Thanks. 😀
I had to use 4 different sources to make my project work.
It wouldn’t be nice to force others to go trough the same amount of trouble when i already have the files.

I made a git repo with the schematic and yaml file for you, if you have any questions feel free to ask.
I may not know the answer, but i’ll do my best to help.

I actually have a working’ish prototype of this project laying on my table right now.
It’s a 120mm noctua fan being controlled by pwm i relation to the temperature. It also has an oled screen to show temp and fan speed. All controlled trough home assistant via esphome.
I say working’ish because the temp sensor i’m using (dht11) is unreliable and is messing up half the time, so i’m looking into buying a DS18B20 instead.
I’d be happy to share schematics and code if you’d like it.

I’m happy to help.
Good luck with proxmox and selfhosting.

It took some time as i had to find a moment to translate my notes.
I did my best with formatting but for some reason new paragraphs aren’t a thing i can get working in an untiered list in a lemmy comment 🤷
I presume some basic knowledge of linux and how to install an OS on a machine, but i’ve tried to add every single step with commands.
If anybody knows an easier way or have any comments regarding this, feel free to educate me.

Here is the way i installed it:

Switching the kernel:

• Install default debian bookworm without desktop environment, but with “standard systems utilities” and “ssh server”
  • Don’t forget to LUKS it, or else you could have just used the proxmox iso 😉
  • SSH server could probably be omitted if everything is done directly on the machine, but i wanted it so i could copy/paste commands
• Boot and log in as root
• Check /etc/hosts and change the ip in front of the hostname to the static ip of the machine
• Check with hostname --ip-address, it should return the ip-address
• Add proxmox repo with echo "deb [arch=amd64] http://download.proxmox.com/debian/pve bookworm pve-no-subscription" > /etc/apt/sources.list.d/pve-install-repo.list
• Add proxmox key with wget https://enterprise.proxmox.com/debian/proxmox-release-bookworm.gpg -O /etc/apt/trusted.gpg.d/proxmox-release-bookworm.gpg
• Run apt update && apt full-upgrade
• Install proxmox kernel with apt install proxmox-default-kernel
• Restart with systemctl reboot
• NOTE: The machine will boot and get stuck on loading initial ramdisk, type in the LUKS key and press enter despite not getting a prompt

Installing the packages

• Install Proxmox packages with apt install proxmox-ve postfix open-iscsi chrony
  • Postfix needs to be configured, if no mailserver choose local only and let system name stay as default
• Remove debian kernel with apt remove linux-image-amd64 'linux-image-6.1
• Update and check grub config with update-grub
  • Seems redundant, because i think it does this by it self when running the command above
• If proxmox is the only OS, remove os-proper with apt remove os-prober
  • This gave me an error about it not being empty, but it fixed itselv after a reboot
• I think a reboot is needed here, but i honestly don’t remember. If in doubt run systemctl reboot

Adding SSH access for root user
It’s easier to copy/paste commands, this requires SSH access to the server
This can be done at any point. I did it as soon as i installed debian, and then removed it as i booted into proxmox

• Edit /etc/ssh/sshd_config with nano /etc/ssh/sshd_config
• Around line 32 find #PermitRootLogin without-password and make en new line below it and write PermitRootLogin yes.
  • The commented line can be edited but i find it easier to add the line as it needs to be removed again later
• Restart the SSH server with /etc/init.d/ssh restart
• When done with copy/pasting the commands it’s better to remove root SSH access again, this is done by removing the line that was added above

Removing debian user
This removes the user that was made as part of installing debian. It can probably be used, but i found it better to add all needed users once i got in to proxmox instead the [username] of course needs to be changed out for the username you used when you installed debian.

• Log in to the terminal as root
• Find the list of users with grep ‘users’ /etc/group
• Use deluser [username] to remove the user

I have a luks encrypted proxmox machine.
And the easiest way i found to do it was to install debian with full disk encryption and then doing some magic to swap the kernel from debian to proxmox.
Or that’s what i think i did at least. I’m no linux magician, i just use it.
On another server i use dropbear to unlock LUKS over ssh. Those two things should be easy to combine.
I took meticulous notes, so i should be able to give you some direction to go if you need some help and can’t find a decent guide out there.

I can’t seem to find any CVE called crowbar in regards to Android. Only one for PHP and one for SUSE.
Would you mind giving more info to help me find out more?
