Complete Guide: Installing Kali Linux on a VPS for MyZubster

📌 Introduction

This guide provides a comprehensive, step-by-step walkthrough for installing Kali Linux on a Virtual Private Server (VPS). The guide is specifically tailored for the MyZubster ecosystem, a decentralized marketplace where users tokenize real-world assets and trade them using Monero (XMR) as the primary currency.

By running Kali Linux on a VPS, you can:

Access your security testing environment remotely from anywhere

Scale resources (RAM, CPU, storage) as needed without hardware limitations

Create an isolated environment for security testing without risking your local machine

Run automated security scans 24/7 with minimal operational cost

🔍 Why Kali Linux for MyZubster?

Kali Linux is the de‑facto standard for security auditing and penetration testing, bundling over 600 pre‑installed tools for network scanning, web application testing, and forensics. In the MyZubster ecosystem, Kali Linux serves a critical role:

"Instead of relying on passive security measures or expensive third‑party APIs, I decided to build an autonomous security bot that scans the gateway every hour using Kali Linux tools (nmap, nikto, sqlmap), analyzes the results with a local AI model (DeepSeek R1:1.5B running on Ollama), and acts automatically: blocks suspicious IPs, suspends users, cancels open orders. Everything runs locally – zero data shared with third parties, zero ongoing costs."

📦 Installation Methods

There are three primary methods to install Kali Linux on a VPS. The choice depends on your provider and specific needs.
Method 1: One-Click Template (Simplest & Recommended)

Many providers offer Kali Linux as a pre-configured template. This is the fastest method.

For Hostinger (detailed steps) :

Log in to hPanel with your Hostinger account.

Navigate to VPS → Manage.

In the left sidebar, go to OS & Panel → Operating System.

Scroll to the Change OS section.

Select the Plain OS tab, then choose Kali Linux from the list.

Click the Change OS button.

When the pop-up appears, check the acknowledgment box and click Next.

Set a new password for your Kali Linux template when prompted.

Wait up to 10 minutes for the setup to complete.

For Linode:

Two options are available:

Kali as a Distribution: Creates a bare-bones install with kali-linux-core only. Select Kali Linux from the "Image" dropdown during instance creation.

Kali from the Marketplace: Deploys Kali with more tools pre-installed. Select "Marketplace" → "Kali Linux" and configure the metapackages you want installed.

For Other Providers: Services like DigitalOcean and Vultr allow custom ISO uploads for maximum flexibility.
Method 2: Converting Debian/Ubuntu to Kali

If your provider doesn't offer Kali directly but supports Debian/Ubuntu, you can convert it.

Connect to your VPS via SSH:
bash

ssh root@your-vps-ip

Modify APT sources to include Kali repositories:
bash

sudo vim /etc/apt/sources.list

Add this line:
text

deb http://http.kali.org/kali kali-rolling main contrib non-free non-free-firmware

Update and install Kali metapackages:
bash

sudo apt update
sudo apt install kali-linux-headless -y

This installs the core Kali tools without the GUI, ideal for a server environment.

Method 3: Manual Installation from ISO (Advanced)

Use this method if you need full control and your provider supports boot from ISO.

Download the Kali ISO (recommend the netboot version for minimal install).

Upload or mount the ISO through your VPS control panel.

Reboot the VPS and start the installation from the ISO.

Follow the on-screen prompts:

    Choose language, region, and keyboard layout.

    Set hostname and create a non-root user.

    For a headless server, skip desktop environment installation.

    Install GRUB bootloader on the main disk.

Reboot and remove the ISO, then connect via SSH.

🔧 Post-Installation Configuration

After installation, perform these essential security steps:

1. Update the System bash

sudo apt update && sudo apt full-upgrade -y

1. Install Essential Kali Metapackages

For MyZubster security scanning, install the necessary tools:
bash

Install core scanning tools

sudo apt install nmap nikto sqlmap -y

For a complete Kali environment (larger footprint):
bash

sudo apt install kali-linux-default -y

For a headless server with no GUI:
bash

sudo apt install kali-linux-headless -y

1. Configure UFW Firewall bash

sudo ufw allow 22/tcp # SSH
sudo ufw allow 3000/tcp # MyZubster Gateway
sudo ufw allow 443/tcp # HTTPS
sudo ufw enable

1. Enable SSH Key Authentication (Disable Password Login) bash

Generate SSH key pair on your local machine

ssh-keygen -t ed25519 -C "[e-mail]"

Copy public key to VPS

ssh-copy-id root@your-vps-ip

Disable password authentication in /etc/ssh/sshd_config

PasswordAuthentication no

1. Install and Configure Ollama (for DeepSeek AI) bash

curl -fsSL https://ollama.com/install.sh | sh
ollama pull deepseek-r1:1.5b

1. Verify Installation bash

ssh -T [e-mail] # Should show: Hi DanielIoni-creator!

🔄 Integrating Kali with MyZubster: The Security Bot

Your Kali VPS can run a Python security bot that automates vulnerability scanning and threat response. Here's a simplified implementation based on the production system:
python

!/usr/bin/env python3

import subprocess
import requests
import json

MYZUBSTER_API = "http://localhost:3000/api"
TOKEN = None

def login():
"""Authenticate with MyZubster API"""
global TOKEN
resp = requests.post(f"{MYZUBSTER_API}/auth/login",
json={"email": "[e-mail]",
"password": "Test123!"})
TOKEN = resp.json().get('token')

def ask_deepseek(prompt):
"""Send analysis request to local DeepSeek model"""
resp = requests.post(f"{MYZUBSTER_API}/ai/ask",
json={"prompt": prompt},
headers={'Authorization': f'Bearer {TOKEN}'})
return resp.json().get('response')

def scan_gateway():
"""Run nmap scan on gateway ports"""
result = subprocess.run(['nmap', '-p', '3000,80,443', 'localhost'],
capture_output=True, text=True)
return result.stdout

def block_ip(ip):
"""Block a suspicious IP using ufw"""
subprocess.run(['ufw', 'deny', 'from', ip], check=False)

def main():
login()
print("🔍 Starting security scan...")
scan_results = scan_gateway()

# Send to DeepSeek for analysis
analysis = ask_deepseek(
    f"Analyze this nmap scan and list any security concerns:\n{scan_results}"
)

# Log and act on findings
with open('/var/log/security_bot.log', 'a') as log:
    log.write(f"{analysis}\n")

if name == "main":
main()

Automate with Cron (Run Every Hour)
bash

crontab -e

Add this line:

0 * * * * /usr/bin/python3 /root/security_bot.py >> /var/log/security_bot.log 2>&1
