Whonix hostname

host

In the case of Whonix, the hostname is always set to "host".

RaspberryPI OS

The default hostname on a fresh Raspberry Pi OS install is raspberrypi

AWS EC2 Hostname

When you launch an EC2 instance with a Hostname type of Resource name, the guest OS hostname is configured to use the EC2 instance ID.

i-0123456789abcdef.ec2.internal 16 alpha numeric or 16 HEX string

Format for an instance in any other AWS Region: ec2-instance-id.region.compute.internal:

i-0123456789abcdef.us-west-2.compute.internal

Variables to test for yourself

not sure where you would add them?

#! /bin/bash
# Amazon EC2 ID
region=("us-east-2" "us-east-1" "us-west-1" "us-west-2" "af-south-1" "ap-east-1" "ap-south-2" "ap-southeast-3" "ap-southeast-4" "ap-south-1" "ap-northeast-3" "ap-northeast-2" "ap-southeast-1" "ap-southeast-2" "ap-northeast-1" "ca-central-1" "eu-central-1" "eu-west-1" "eu-west-2" "eu-south-1" "eu-west-3" "eu-south-2" "eu-north-1" "eu-central-2" "il-central-1" "me-south-1" "me-central-1" "sa-east-1")
RANDregion="${region[ RANDOM % ${#region[@]} ]}"
EC2region=(".ec2" "."$RANDregion".compute")
EC2final="${EC2region[ RANDOM % ${#EC2region[@]} ]}"
EC2=$(echo "i-$(tr -dc a-z0-9 </dev/urandom | head -c 16)""$(echo $EC2final)".internal)
# Android 
ANDROID_ID=$(hexdump -n8 -e'4/4 "%08X" 1 "\n"' /dev/urandom | tr "A-Z" "a-z") # Android 64 hex 16 char string
Android="android_$(echo $ANDROID_ID)"
# Windows
WIN=("windows10" "WSL" "Windows11" "Win10" "win10-vm" "wsl" "windows11" "Win11" "win11-vm" "Windows10")
WINDOWS="${WIN[ RANDOM % ${#WIN[@]} ]}"
# Virtual Host
VHnum=$(shuf -n 1 -i 0-10)  # Red Hat Virtual Host Number
# ChromeOS
CHROMEid=$(tr -dc 0-9 </dev/urandom | head -c 6)
CHROMElist=("ChromeOS" "pixelbook" "ChromeOS"_"$CHROMEid" "chromebook")
CHROME="${CHROMElist[ RANDOM % ${#CHROMElist[@]} ]}"
echo "$EC2"
echo "$Android"
echo "$WINDOWS"
echo "Virtual-Host $VHnum"
echo "$CHROME"

It may be better to use the Android HEX generation for the amazon EC2 ID 16 char string instead of the one above
