ko-fi GitHub stars Python Status License: MIT

Ragnar is a fork of the awesome Bjorn project — a Tamagotchi-like autonomous network scanning, vulnerability assessment, and offensive security tool. It runs on a Raspberry Pi with a 2.13-inch e-Paper HAT, as a headless server on Debian-based systems (AMD64/ARM/ARM64) with Ethernet-first connectivity, or on the WiFi Pineapple Pager with full-color LCD display. On servers with 8GB+ RAM, Ragnar unlocks advanced capabilities including real-time traffic analysis and enhanced vulnerability scanning.

Important

For educational and authorized testing purposes only.

Quick Install

# On Raspberry Pi: choose between e-Paper HAT, server/headless, or Pineapple Pager deployment.
# On other hardware: choose between server install or Pineapple Pager deployment.
# It may take a while as many packages and modules will be installed. Reboot when it finishes.

For detailed information see the Install Guide.

🌐 Web Interface

Access Ragnar's dashboard at http://<ragnar-ip>:8000

  • Real-time network discovery and vulnerability scanning
  • Multi-source threat intelligence dashboard
  • File management with image gallery
  • System monitoring and configuration
  • Hardware profile auto-detection (Pi Zero 2W, Pi 4, Pi 5)

WiFi Configuration Portal — When Ragnar can't connect to a known network, it creates a WiFi hotspot:

  1. Connect to WiFi network Ragnar (password: ragnarconnect)
  2. Navigate to http://192.168.4.1:8000
  3. Configure your WiFi credentials via the mobile-friendly interface
  4. Ragnar will automatically retry known WiFi after some time if the AP is unused
  5. Once configured, Ragnar exits AP mode and connects to your network

The portal supports network scanning with signal strength, manual entry for hidden SSIDs, known network management, and one-tap reconnection.

🐝 Ragnar + Pwnagotchi Side by Side

A bundled helper script plus dashboard controls make swapping between Ragnar and Pwnagotchi painless:

  1. Run the installer:

    cd /home/ragnar/Ragnar
sudo ./scripts/install_pwnagotchi.sh

    The script clones pwnagotchiworking into /opt/pwnagotchi, installs dependencies, writes /etc/pwnagotchi/config.toml, and drops a disabled pwnagotchi.service. Re-running is fast — it skips already-installed packages.

  2. Open the web UI → Config tab → Pwnagotchi Bridge → click Switch to Pwnagotchi.

Requirements:

  • USB WiFi adapter (wlan1) with monitor mode support
  • Waveshare 2.13" e-Paper HAT V4 for the pwnagotchi face display

Pwnagotchi web UI: http://<same-ip>:8080 (credentials: ragnar / ragnar)

What the installer configures:

  • Monitor mode scripts (/usr/bin/monstart, /usr/bin/monstop)
  • e-Paper display type (waveshare213_v4) and rotation
  • Web UI on port 8080, Pwngrid disabled
  • RSA keys, log directories, bettercap integration

Swapping via PiSugar 3 button:

Button Action While Ragnar is running While Pwnagotchi is running
Single tap Toggle manual mode —
Double tap Switch to Pwnagotchi Switch to Ragnar
Long press Switch to Pwnagotchi Switch to Ragnar

A 10-second cooldown prevents accidental double triggers. If PiSugar is not connected, the listener is silently disabled.

Static IP recommended: When switching modes, WiFi may briefly reconnect with a different DHCP IP. Set a static IP:

sudo nmcli con mod "YOUR_WIFI_SSID" ipv4.method manual \
  ipv4.addresses "192.168.1.211/24" \
  ipv4.gateway "192.168.1.1" \
  ipv4.dns "192.168.1.1"
sudo nmcli con up "YOUR_WIFI_SSID"

Or set a DHCP reservation on your router. This only affects wlan0 — the monitor interface (wlan1/mon0) is not changed.

Service recovery: If Ragnar doesn't start after a reboot:

sudo /home/ragnar/Ragnar/scripts/fix_services.sh

🍍 WiFi Pineapple Pager

Ragnar can be deployed to the WiFi Pineapple Pager as a native payload with full-color LCD display, button controls, and LED status indicators.
