User-Hosted License Servers
User-hosted license servers run on your own infrastructure. You manage deployment, maintenance, and security. Vantage connects to them at job time to check out licenses.
When to use user-hosted
- You already have license servers running and don't want to migrate.
- Compliance or data-residency requirements mandate that licenses stay on your infrastructure.
- You need custom configurations not supported by the Vantage-hosted option.
What you need
- A license server (FlexLM, RLM, LMX, LS-DYNA, DSLS, or OLicense) running on a machine that Vantage clusters can reach over the network.
- The server hostname or IP address and port.
- Any required credentials or access keys.
Network requirements
Vantage clusters must be able to reach the license server on its vendor-specific port. Typical setups involve:
- Opening the license server port in your firewall to Vantage's control-plane IP range (contact support for the current range).
- Configuring DNS or using a static IP so the endpoint doesn't change.
- For HA, running two or more license servers and pointing Vantage to all endpoints.
Setup steps
- Install and configure your license server software following the vendor's instructions.
- Install your license files on the server and verify licenses are served locally.
- Register the server in Vantage — In the left sidebar, click Licenses, then select Configurations. Click Add License Server, and enter the type, hostname, port, and credentials.
- Test checkout — Submit a job that requires a license from that server. Vantage checks out the license before the job starts and releases it on completion.
Monitoring
User-hosted servers appear on the Licenses page with live usage counts — total, checked-out, available. Server health is reported as reachable or unreachable based on periodic connectivity checks from the Vantage control plane.
Troubleshooting
| Problem | Likely cause |
|---|---|
| Server shown as unreachable | Firewall blocking the license port; DNS resolution failure |
| License checkout fails | Server out of licenses; feature name mismatch; expired license file |
| Intermittent failures | Network latency or packet loss between Vantage and your server |
