Technical Details

what runs on :1715

Houdini license-manager deployments normally listen on TCP port 1715; the IANA registration covers both TCP and UDP, although ordinary Houdini licensing traffic is primarily encountered over TCP. Clients use a proprietary request/response protocol to check out and renew Houdini licenses from the license server, typically using the default port unless the server has been configured otherwise. It is not a web service or a general-purpose remote shell.

security overview

This service should generally be reachable only by trusted Houdini workstations and render infrastructure, preferably through firewall allowlists or a private network. Internet exposure can disclose licensing-service behavior and provides an attack surface for implementation vulnerabilities or abuse of the licensing service; the protocol should not be treated as an internet-facing encrypted service.
