## TPM2 Luks Decryption
|
|
|
|
Mostly taken from here:
|
|

PCR reference for `--tpm2-pcrs` args
|
|
|
|
```text
|
|
0: System firmware executable
|
|
2: Kernel
|
|
4: Bootloader
|
|
7: Secure boot state
|
|
8: Cmdline
|
|
9: Initrd
|
|
```
|
|
|
|
Basic commands:
|
|
|
|
```bash
|
|
# Show tpm2 devices
|
|
systemd-cryptenroll --tpm2-device=list
|
|
# Show crypto luks block devices
|
|
blkid -t TYPE=crypto_LUKS
|
|
|
|
# Enroll the tpm2 device with systemd-cryptenroll
|
|
systemd-cryptenroll --tpm2-device=auto --tpm2-pcrs=0,2,4,7,8,9 /dev/nvme0n1p3
|
|
|
|
# Reenroll
|
|
systemd-cryptenroll /dev/nvme0n1p3 --wipe-slot=tpm2 --tpm2-device=auto --tpm2-pcrs=0,2,4,7,8,9
|
|
|
|
# Append to command line args
|
|
rpm-ostree kargs --append=rd.luks.options=tpm2-device=auto
|
|
```
|
|
|
|
When you update you'll need to reenroll. Add this to your ~/.bashrc
|
|
|
|
```bash
|
|
# LUKS TPM2 commands
|
|
alias tpm2-reenroll='sudo systemd-cryptenroll /dev/nvme0n1p3 --wipe-slot=tpm2 --tpm2-device=auto --tpm2-pcrs=0,2,4,7,8,9'
|
|
```
|
|
|
|
## Podman
|
|
|
|
Since you'll be using podman for most container-based services, you'll want to set the
|
|
the podman auth file to somewhere persistent, otherwise it'll get deleted every time you
|
|
reboot.
|
|
|
|
Add this to your `.bashrc`:
|
|
|
|
```bash
|
|
# Podman auth file
|
|
export REGISTRY_AUTH_FILE=$HOME/.podman-auth.json
|
|
```
|
|
|
|
Source that and then run `podman login` to create the file.
|
|
|
|
### Autostarting services with quadlets
|
|
|
|
If you want to run something as your user at boot (like a systemd process, think ollama) you can
|
|
create a user quadlets like so:
|
|
|
|
```bash
|
|
# Generate the .container file
|
|
podman run --rm ghcr.io/containers/podlet --install --description "Local AI" \
|
|
podman run \
|
|
-d \
|
|
-v ollama:/root/.ollama \
|
|
-p 11434:11434 \
|
|
--name ollama \
|
|
--restart always \
|
|
docker.io/ollama/ollama > ~/.config/containers/systemd/ollama.container
|
|
|
|
# Verify the service (Note the filename:service, this is required! You will get "Failed to prepare filename" without it)
|
|
systemd-analyze verify ~/.config/containers/systemd/ollama.container:ollama.service
|
|
|
|
# Start the service
|
|
systemctl --user daemon-reload
|
|
systemctl --user start ollama
|
|
```
|
|
|
|
## rpm-ostree
|
|
|
|
Note: if you don't need them, remove extra repos
|
|
|
|
I removed:
|
|
|
|
1. rpmfusion-nonfree-steam.repo
|
|
2. rpmfusion-nonfree-nvidia-driver.repo
|
|
3. google-chrome.repo
|
|
4. _copr\:copr.fedorainfracloud.org\:phracek\:PyCharm.repo
|
|
|
|
```bash
|
|
# Search for available packages
|
|
rpm-ostree search git
|
|
|
|
# Install a package
|
|
rpm-ostree install git
|
|
|
|
# Apply the installed package live
|
|
rpm-ostree apply-live
|
|
|
|
# Check what's been layered
|
|
rpm-ostree status
|
|
```
|
|
|
|
### Git, Vim, etc
|
|
|
|
Some packages are nice to have at the system level.
|
|
|
|
```bash
|
|
rpm-ostree install git vim
|
|
```
|
|
|
|
### Libvirt, Qemu, KVM
|
|
|
|
```bash
|
|
rpm-ostree install virt-manager libvirt
|
|
systemctl enable --now libvirtd
|
|
```
|
|
|
|
## Network
|
|
|
|
### Hostname
|
|
|
|
```bash
|
|
sudo hostnamectl hostname reesework16
|
|
```
|
|
|
|
### VLAN Setup with nmcli
|
|
|
|
```bash
|
|
# VLAN 2
|
|
nmcli conn
|
|
export NMCLI_DEVICE=enp195s0f4u1u3
|
|
nmcli connection add type VLAN con-name $NMCLI_DEVICE.2 dev $NMCLI_DEVICE id 2
|
|
```
|
|
|
|
## GPU Support in Distrobox
|
|
|
|
Fix for `error="failed to check permission on /dev/kfd: open /dev/kfd: invalid argument"`
|
|
|
|
```bash
|
|
# You have to create the video and render group to /etc/group before you can use it
|
|
sudo grep -E '^video:' /usr/lib/group | sudo tee -a /etc/group
|
|
sudo grep -E '^render:' /usr/lib/group | sudo tee -a /etc/group
|
|
sudo usermod -aG video $USER
|
|
sudo usermod -aG render $USER
|
|
```
|
|
