Ensure that your license IP masks are set to match your network infrastructure, including any VPN subnets. By default your Houdini licenses are keyed to the following private networks:

LAL licenses:
* +.+.., 192.168.., 10..., 172....
where +.+.. is the network of the license server

GAL licenses:
* +..., 192.168.., 10..., 172....
where +... is the network of the license server

If you have additional networks not included in the default IP Mask of your Houdini licenses, contact support@sidefx.com to have a Change IP Mask entitlement issued to further open or restrict the network range of these licenses.

If the support team issues you a custom IP Mask for your Houdini licenses, you will need to create a control file on the license server called sesinetd.options. Please refer to Networking for sesinetd.options

Firewall

• License server program sesinetd (HoudiniLicenseServer) needs incoming TCP port 1715.
• Allow traffic to be routed to the license server on TCP port 1715 to the license server machine.
• The client program hserver (HoudiniServer) will listen on TCP port 1714.
• For more information about how to test the Houdini license server port please refer to Firewall setup
