Home Linux Lab

Build a Home Linux Lab with Raspberry Pi

Turn your Raspberry Pi into a portable Linux lab using Raspberry Pi Imager. This guide walks you through flashing the OS, enabling SSH, configuring Wi-Fi, and getting the system ready for headless or desktop use.

🔧 What You’ll Need

  • Raspberry Pi 3B, 4, 400, or 5

  • microSD card (16GB minimum, 32GB+ recommended) or USB SSD

  • Raspberry Pi Imager (on Windows/macOS/Linux)

  • USB keyboard, HDMI cable, and monitor (for first boot if not headless)

  • Wi-Fi or Ethernet access

Step 1: Download Raspberry Pi Imager

  1. Go to: https://www.raspberrypi.com/software

  2. Download the Imager for your OS.

  3. Install and launch the application.

Step 2: Choose Your OS Image

  1. Click “Choose OS”.

  2. Scroll to Other general-purpose OS > Ubuntu.

    • Recommended: Ubuntu Desktop (22.04 LTS) for GUI

    • Or: Ubuntu Server (22.04 LTS) for headless use

    • For Kali/Parrot: Choose Use custom and select your .img file downloaded from Kali or Parrot

Step 3: Choose Storage

  1. Insert your microSD or USB drive.

  2. Click “Choose Storage” and select the correct device.

⚠️ Warning: This will erase the entire drive.

Step 4: Preconfigure Settings (Wi-Fi, SSH, Hostname)

  1. Click the ⚙️ gear icon in the bottom-right of Raspberry Pi Imager.

  2. Enable:

    • Set hostname: e.g. homelab-pi

    • Enable SSH: Select password or public key auth

    • Set username and password

    • Configure Wi-Fi: Enter SSID, password, and country

    • Optional: Set locale and timezone

  3. Click Save to store these settings before flashing.

🧠 This step makes it headless-ready out of the box.

Step 5: Flash the Image

  1. Click “Write”.

  2. Confirm when prompted.

  3. Wait for it to complete (5–15 minutes).

Step 6: Boot the Raspberry Pi

  1. Insert the SD/USB into your Raspberry Pi.

  2. Connect power and optionally HDMI/keyboard.

  3. First boot may take a few minutes while it resizes partitions.

Step 7: Connect via SSH (Optional)

If you enabled SSH and Wi-Fi:

bash
ssh username@homelab-pi.local

If .local doesn’t resolve, find your Pi’s IP from your router and use:

bash
ssh username@<IP_ADDRESS>

Step 8: Post-Setup Essentials

Once you’re in:

bash
sudo apt update && sudo apt upgrade -y

Optional installations (depending on use-case):

bash
sudo apt install net-tools htop fail2ban git curl -y

Desktop environments for Server editions:

bash
sudo apt install ubuntu-desktop -y

For Kali or Parrot, skip this—they come preloaded with tools.

🧪 Use Case Ideas for Your Home Lab

  • 🔍 Run pentesting tools (Kali/Parrot)

  • 🧠 Practice system hardening

  • 🛡️ Build and test firewall rules

  • 🧰 Host your own DNS, VPN, PiHole, or web server

  • 🧪 Test scripts in a controlled Linux sandbox

💡 Tip: Make It Modular

Want to switch OS easily? Flash new images to other SD cards or USB sticks and hot-swap. Use PiBakery or scripts to preconfigure more complex setups.
