When using node-locked (host-based) FlexLM licensing, after setting up bridged networking for models an error is seen when attempting to start the model stating that the hostid does not match the licence:
ERROR: License check failed! No licences 'MaxCore_SystemGenerator' available. Hostid doesn't match license. License files searched: ... Error Code : -9
This problem may also be seen with other software products which use a node-locked FlexLM licencing model.
There is a known issue with bridged networking under Windows whereby creating an Ethernet bridge results in FlexLM reporting a different hostid for the machine. For example, before an Ethernet bridge is created for Model bridged networking, the FlexLM 'hostid' utility reports the following:
C:/> lmutil.exe hostid lmutil - Copyright (c) 1989-2008 Acresso Software Inc. All Rights Reserved. The FLEXnet host ID of this machine is "000c29600725"
After creating a Windows Ethernet bridge 'hostid' now reports:
C:/> lmutil.exe hostid lmutil - Copyright (c) 1989-2008 Acresso Software Inc. All Rights Reserved. The FLEXnet host ID of this machine is "020c29600725"
Note the first two digits '00' have changed to '02' - in certain circumstances the host id may be totally different.
The FlexLM host id is based on the host machine's Ethernet MAC address, and creating an Ethernet bridge has the effect of hiding the original machine's MAC address and creating a new MAC address.
There are two options to solve this problem:
This resolution disables Ethernet MAC bridging between the model and the physical network. This will prevent the model from communicating with the outside world.
To remove the Ethernet bridge:
You should now find that the FlexLM hostid has returned to it's original (pre-bridge) value, and that the FastModel should successfully start.
This resolution uses NAT-based networking instead of bridging. In this configuration the model shares the same external IP address as the host machine. See ARM Knowledge Base article:
