Issue:
The Autodesk® License Manager (AdLM), which is based on FLEXlm® technology, does not start because the required port for the Autodesk vendor daemon, ADSKFLEX, is blocked or is in use by another application
Resolution:
The Autodesk vendor daemon uses TCP port 2080. This port is officially registered to Autodesk through the Internet Assigned Numbers Authority (IANA). Every attempt should be made to reassign the port in the conflicting application, or to unblock port 2080 as required. If you are unable to reassign or unblock the port, you can change the Autodesk vendor daemon port. The port number needs to be changed in the license file.
To change the vendor port number:
1. Open the license file with Notepad. In the third line of the license file, delete the follwing text:
port=2080
2. Save the license file.
3. Use LMTOOLS to stop the license manager.
4. Wait 30 seconds to allow the license manager to shut down fully, and then restart the license manager.
The license manager will now start and the adskflex vendor daemon will seek an available tcp port. Unless all ports are being blocked on the license server, this technique will find an available port.
5. After the license manager has started, examine the debug.log file. A line in the debug.log file will indicate which TCP port is being used. For example, the following line identifies the use of TCP port 1093:
10:20:40 (lmgrd) adskflex using TCP-port 1093
