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 collect ip neigh data 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:
```
lan-graph serve --host 0.0.0.0 --port 8000
```
Open http://localhost:8000 in 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, and ssh in place.
