UDP 5093
Synopsis
- UDP port 5093 is assigned to SentLM (Sentinel License Manager), used by Thales/SafeNet/Aladdin “Sentinel RMS” licensing.
- Sentinel RMS license servers use UDP 5093 for client broadcast discovery and heartbeats (often alongside TCP 5093 for license checkouts).
- Altair HyperWorks (Altair License Manager) uses Sentinel RMS and relies on UDP 5093 to discover its license server.
- Hexagon/Intergraph PPM products such as SmartPlant/Smart 3D that use Sentinel RMS also depend on UDP 5093 for client–server discovery.
- Older “Sentinel LM” deployments and associated utilities (e.g., lserv, lsmon) similarly communicate over UDP 5093.
