LAN Graph Explorer
A local LAN discovery service that pings every host on your primary subnet, optionally uses SSH key-based auth to query remote neighbors, and presents a Visio-style map via D3.
Features
- Detects your default IPv4 network and gateway automatically.
- Pings each active host and performs reverse DNS lookup.
- Attempts passwordless SSH (honoring
SSH_USER/SSH_KEY_PATH) to collectip neighdata so we can draw edges between hosts. - Serves a FastAPI backend and a D3-powered front-end that renders nodes/edges interactively.
Getting started
- Install dependencies (ideally inside a virtualenv):
pip install --upgrade pip pip install fastapi uvicorn[standard] typer - Run a scan from the command line:
lan-graph scan --concurrency 64 --ssh-timeout 5 - Start the UI server:
Open
lan-graph serve --host 0.0.0.0 --port 8000http://localhost:8000in a browser to see the topology.
SSH key authentication
Set environment variables so the scanner uses your preferred SSH identity:
export SSH_USER=team
export SSH_KEY_PATH=~/.ssh/id_rsa
The tool runs ssh -o BatchMode=yes and will skip hosts where it cannot connect quickly.
Testing
pip install pytest
pytest
Notes
- The graph draws gateways, the scanning host, and any discovered neighbor relationships for hosts that allow
ssh. - It's designed to run on Linux machines with
ip,ping, andsshin place.
