Synopsis

  • TCP port 1947 is used by the Thales/Gemalto/SafeNet Sentinel LDK (formerly Sentinel HASP) License Manager service (process name often hasplms).
  • It serves the Sentinel Admin Control Center web UI at http://localhost:1947 and handles USB/soft‑license dongles for protected apps.
  • Real‑world software using it includes Esko Automation Engine/ArtPro+, ONYX Graphics ONYX RIP, SolidCAM, Cimatron, and 3Shape Dental System.
  • You’ll commonly see it on Windows servers/workstations where vendors install the Sentinel LDK Runtime for network or local licensing; the same applies on Linux/macOS where supported.
  • Security note: this service on 1947 has had multiple CVEs (notably 2017–2021) enabling remote code execution or denial of service via its web component; exposed instances have been abused by attackers, so keep it patched and avoid internet exposure.
