Banner-specific signatures (e.g. AdGuard on port 3000) were incorrectly
matching when nmap returned no banner, causing wrong suggested_node_type
(e.g. 'router' for a media server). Now a signature with banner_regex is
only matched when a banner is present AND matches the regex.
Also make _PORT_TYPE_HINTS always contribute to suggest_node_type found set
(not just as elif fallback) so well-known ports like 8006 still resolve to
proxmox even when a generic sig also matched.
- Expand service_signatures.json from 35 → ~120 entries covering *arr apps,
smart-home (HA, MQTT, ESPHome), cameras (RTSP, Dahua, Tapo, Reolink),
network gear (MikroTik, UniFi, Pi-hole), auth (Authelia, Authentik, Vault),
monitoring (Grafana, InfluxDB, Loki, Uptime Kuma), containers (Portainer),
and many more home lab services
- Expand nmap port range to cover home lab ports (8989, 7878, 8123, 554, 1883, etc.)
and increase --host-timeout from 30s to 120s for reliable -sV detection
- Add _PORT_TYPE_HINTS fallback in suggest_node_type for ports without signatures
(cameras→iot, MQTT→iot, Proxmox→proxmox, MikroTik→router, etc.)
- Show actual port/protocol (e.g. TCP/9999) instead of "unknown_service" so
all open ports are visible even when not matched
- Update tests to reflect new unknown-port label format
