Setting up Qemu with a tap interface

There are two parts to networking within QEMU:

• The virtual network device that is provided to the guest (e.g. a PCI network card).
• The network backend that interacts with the emulated NIC (e.g. puts packets onto the host's network).

Example: User mode network

Arch Linux Full-Disk Encryption Installation Guide

This guide provides instructions for an Arch Linux installation featuring full-disk encryption via LVM on LUKS and an encrypted boot partition (GRUB) for UEFI systems.

Following the main installation are further instructions to harden against Evil Maid attacks via UEFI Secure Boot custom key enrollment and self-signed kernel and bootloader.

Preface

You will find most of this information pulled from the Arch Wiki and other resources linked thereof.

Note: The system was installed on an NVMe SSD, substitute /dev/nvme0nX with /dev/sdX or your device as needed.

Arch Linux Installation

LVM on LUKS Arch installation with systemd-boot

Sources:

• https://wiki.archlinux.org/index.php/Dm-crypt/Encrypting_an_entire_system

Note: If you want a simpler encryption setup (with LUKS only), you can instead use the archinstall "guided" installer included with Arch since April 2021.

Remote unlock via SSH for encrypted root volume

Ubuntu 14.04.3

Install dropbear SSH server with automated hooks for being included in an initramfs.

apt-get install dropbear

Remove default private/public key for login, clear dss key (would be regenererated otherwise), remove insecure 1024-bit RSA host key and generate a new 2048-bit RSA host key (we'll have to keep the DSA-key, dropbear won't start otherwise - make sure to use RSA when connecting):

# You must first install apktool (https://github.com/iBotPeaches/Apktool) and android SDK
# and decompile apk using it 
# apktool d -rf my-app.apk

# then generate a key for sign in:
# keytool -genkey -v -keystore my-release-key.keystore -alias alias_name -keyalg RSA -keysize 2048 -validity 10000
rm signed-app.apk
apktool b -f -d com.myapp
jarsigner -verbose -sigalg SHA1withRSA -digestalg SHA1 -keystore my-release-key.keystore com.myapp/dist/com.myapp.apk alias_name
