How do I set up licensing behind a Firewall?

Ensure these ports are not blocked.

The following TCP/IP ports are used for Houdini

  • HoudiniLicenseServer (sesientd): TCP port 1715
  • HoudiniServer (hserver): TCP port 1714

Test your connection

You can test your port connectivity to the license server by following the steps based on your operating system.

Windows

Open the PowerShell and type the name or the IP address of the license server.

If you have Apprentice, Indie or Commercial workstation licenses, the license server/IP address will be your local machine. If you connect to a remote license server, you will use that machine name or IP address.

Test-NetConnection license-server-name-or-IP -Port 1715
If the client program HoudiniServer (hserver) cannot communicate with the HoudiniLicneseServer(sesinetd) you will see a message similar to: WARNING: TCP connect to computer-or-IP:1715 failed
Linux or OSX

If you have Apprentice, Indie or Commercial workstation licenses, the license server/IP address will be your local machine. If you connect to a remote license server, you will use that machine name or IP address.

In a Terminal type:

nc -v license-server-name-or-IP 1715

If the client program HoudiniServer (hserver) can communicate with the HoudiniLicneseServer(sesinetd) you will see a message similar to:

Connection to computer-name 1715 port [tcp/*] succeeded!
