The FLEXlm server will require a valid license certificate to start server licenses. A license certificate file can be obtained from Autodesk when the product is registered. When requesting a license certificate you will need to provide the host name and host id of the machine that will run the FLEXlm license server. The host name is case sensitive. You can get the host id using the FLEXlm utilities from the command line:./lmutil lmhostid
When you receive your license certificate file, it should be copied to /opt/Autodesk/networklicensemanager.
The FLEXlm server manager can be started manually or configured to start automatically at system startup.
