# Dotfiles # Dotfiles
My personal configuration files. Here you can find my personal configuration files!
## Organization
- `auto`: automatic user level configuration script for common tools; reasonable defaults for every
machine, usually finishes instantly and requires minimal user intervention
- To configure everything, `cd` into the directory and run `./auto`
- To configure an individual piece, `cd` into that specific directory and run `./<name>`
- `manual`: manual user level configuration scripts; may be unsuitable for some machines, may run
for a while and may require user intervention (e.g. monitoring for errors and installing packages
like `gcc`)
- `rust`: installs the Rust programming language and adjust bash config files accordingly. May
consume ~1 GiB of disk space.
- `helix`: installs the Helix editor. May consume ~150 MiB of disk space.
- `setup`: Setup guides for Linux machines, mostly focused on Debian & Ubuntu. Includes
installation guides (dual boot or regular install) and system and user level
setups/configurations.
- `system`: system level utilities
- `mac-fnmode`: fix function keys' behavior when using Mac keyboards
- `sshd`: SSH daemon configuration
- Disables password authentication and only allow SSH public key authentication
- More secure and defeats brute force attempts on simple passwords
- Only users in the `ssh-users` group may log in and prevents remote root log in
- Defeats login attempts on system users and root
- Needs to be temporarily disabled if you need to unmount home partition
- `udev`: lock your screen when new human input devices are plugged in
- Defeats Bad USB attacks.
- `utils`: Utilities. Currently only includes a script to test for true color (24 bit) support,
typically under SSH/Mosh sessions and tmux. A smooth rainbow should be shown on correctly set up
systems.
- `*.asc`: my OpenPGP public keys

# Dual Boot Ubuntu # Ubuntu Installation
## Installation steps with encryption
By following these steps, you will be able to install Ubuntu with a separate `/`, `/home`, and
`/boot`, with everything encrypted except `/boot`. A disk password will be required upon boot and a
separate user password will be required.
- Booting Ubuntu 23.04 live image with `Try Ubuntu` option.
- Verify that we are using UEFI: `$ [ -d /sys/firmware/efi ] && echo UEFI ||
echo BIOS`
- Give 1 GiB (or 500 MiB if you are short on space) for `/boot` using GParted and make a partition
for `/` as well, at least around 25 GB.
- `$ sudo cryptsetup luksFormat --type luks2 --key-size 512 --hash sha512
--use-random /dev/<root partition>`
- Defaults, spell it out if you want to be extra certain:
`--cipher aes-xts-plain64 --iter-time 2000 --verify-passphrase`
- `$ sudo cryptsetup open /dev/<root partition> pvroot`
- No need to overwrite data since it is originally BitLocker encrypted and would
cause loss of performance and lifespan of the SSD.
- `$ sudo pvcreate /dev/mapper/pvroot`
- `$ sudo vgcreate vgroot /dev/mapper/pvroot`
- `$ sudo lvcreate -n lvhome -L 10G vgroot` (`G` refers to GiB according to the
man page)
- Remember to monitor disk usage and when prompted, live extend the LVs!
- `$ sudo lvcreate -n lvroot -L 15G vgroot`
- Start the Ubuntu installation from the shortcut icon on Desktop.
- Choose extra software and set a password.
- Choose `Something else`.
- Format `/dev/<boot partition>` as ext4 and mount to `/boot`.
- Format `/dev/mapper/vgroot-lvroot` as ext4 and mount to `/`.
- Format `/dev/mapper/vgroot-lvhome` as ext4 and mount to `/home`.
- Choose the main disk (e.g. `/dev/sda` or `/dev/nvme0n1p2`) as the `Device for boot loader
installation`.
- Name the partitions if you are feeling fancy.
- Once the installation is complete, click `Continue Testing` to make necessary
changes to load the encrypted partitions at startup.
- Make note of the UUID: `$ blkid /dev/<pvroot-partition>`
- Mount the installed Ubuntu OS on `/mnt` and use `chroot` to change the root
directory to `/mnt`.
```
$ sudo mount /dev/mapper/vgroot-lvroot /mnt
$ sudo mount /dev/<boot partition> /mnt/boot
$ sudo mount --bind /dev /mnt/dev
$ sudo chroot /mnt
# mount -t proc proc /proc
# mount -t sysfs sys /sys
# mount -t devpts devpts /dev/pts
```
- In the chroot: `# vi /etc/crypttab`
- Add the following lines to it (replacing `<UUID_PVROOT>` from the value
obtained from `blkid` command earlier):
```
# <target name> <source device> <key file> <options>
pvroot UUID=<UUID_PVROOT> none luks,discard
```
- This guide assumes you have an SSD so we have `discard`.
- Update the Linux kernel to load encrypted partitions at startup: `#
update-initramfs -k all -c`
- Exit the chroot shell.
- Reboot.
- Select Enroll MOK at the blue screen MOK manager. Be quick! After a minute
or so it would reboot and you only get one chance.
- Select continue and yes.

## Grub background ## Services & System configs
### Tool ### Swap partition/file
- `$ sudo apt install grub-customizer` - Allocate 16 GiB for LVM swap partition (if not set during installation):
- Put in background manually
### Manual Script
```
sudo mkdir /opt/grub
sudo cp -r background/ /boot/grub/
sudo chown -R root:root /opt/grub
sudo chmod -R 700 /opt/grub
```
- Add the following lines to `/opt/grub/cycle-backgrounds.sh`:
``` ```
#!/bin/sh sudo lvcreate -n lvswap-ubuntu-23.04 -L 16G -C y vgroot
cd /boot/grub/background # note down UUID:
mv background.png tmp.png sudo mkswap /dev/mapper/vgroot-lvswap--ubuntu--23.04
mv background-1.png background.png echo 'UUID=<UUID> none swap swap 0 0' | sudo tee -a /etc/fstab > /dev/null
mv tmp.png background-1.png sudo swapon -a
```
- Or, allocate 8 GiB for swapfile:
```
# if /swapfile already exists
sudo swapoff /swapfile
sudo fallocate -l 8GiB /swapfile
sudo chmod 0600 /swapfile
sudo mkswap /swapfile
sudo swapon /swapfile
echo '/swapfile none swap defaults 0 0' | sudo tee -a /etc/fstab > /dev/null
``` ```
- `$ sudo chown root:root /opt/grub/cycle-backgrounds.sh`
- `$ sudo chmod 700 /opt/grub/cycle-backgrounds.sh`
- Add `@reboot /opt/grub/cycle-backgrounds.sh` to root crontab.
- In `/etc/default/grub`:
- Add `GRUB_BACKGROUND=/boot/grub/background/background.png`
- Change `GRUB_TIMEOUT=10` to `GRUB_TIMEOUT=3`
- `$ sudo update-grub`
