Netbox Scanner

This repository includes a simple Dockerized network scanner and a NetBox importer.

Services

• scanner: runs scan.py and saves scan results to output/network.txt
• netbox-importer: runs ipscan-v2.py and imports scan results into NetBox

Files

• scan.py: performs Nmap scans for configured networks and writes network.txt
• ipscan-v2.py: imports scan results into NetBox using environment variables
• docker-compose.yml: defines scanner and netbox-importer services
• Dockerfile: installs Python and Nmap and copies both scripts into the container

Usage

Build and run the scanner

docker compose build
docker compose up scanner

The scan output is written to:

./output/network.txt

Run the NetBox importer

docker compose up netbox-importer

Configuration

Scanner service

• OUTPUT_PATH: path to save results inside container (default: /app/output/network.txt)
• SCAN_NETWORKS: comma-separated CIDR networks to scan (default set in scan.py)

NetBox importer service

• NETBOX_URL: NetBox API URL
• NETBOX_TOKEN: NetBox API token
• NETWORKS: comma-separated networks to scan
• TENANT: NetBox tenant name
• SSL_VERIFY: whether to verify SSL (false, 0, no disable verification)
• SCAN_SOURCE: env, netbox, or mixed (use NetBox prefix data for scan networks)
• NETBOX_PREFIX_STATUS: optional prefix status filter for NetBox prefixes (for example active)

Output format

The generated network.txt file includes scan results in this format:

# network.txt generated on 2026-05-20T00:00:00Z
# host status open_ports
192.168.85.1 up 22 80
192.168.85.2 down

Notes

• Ensure nmap is installed in the container via the provided Dockerfile.
• If you want to run both services together, use:

docker compose up scanner netbox-importer
