The vendor daemon port is by default a dynamic port that can change when the license server undergoes a restart as a result of re-installing a license or just simply routine server maintenance. When running within a single network (e.g. on premises), this isn’t a problem. But if you want to use your licenses outside your local network, you’ll need to fix vendor ports so that firewalls don’t get in the way.
Note: Before making any changes to the vendor ports, make sure you temporarily shut down the on-premises license server machine or the license manager and make sure there are no running jobs making use of the licenses.
To fix the vendor ports, follow the steps listed below:
- Decide on your vendor ports.
- We recommend that you choose a vendor port that is easy to remember, like a number ending with 0s. For example, you can choose to fix the vendor port to 27000 or 28000, as long as that port is open on your firewall/gateway and not being used by any other software application.
- If you have more than 1 license file, you should fix the vendor port in all the license files. Otherwise, you will get an error when you restart the license server. You need to fix the vendor port in all the license files that are associated with the server.
- Open your license files to edit as an administrator
- Add a vendor port if one is not already set. How you do this will depend on the license manager and application. Some common examples:
- Once the vendor port is fixed in the license file, Save and close the license file.
- Verify that you’ve changed the file by re-opening the file and checking that your changes are there.
- Once you verify the vendor port was fixed, restart the license server or the license manager.
- Check the license log file to see if the vendor port is the one you fixed in the license file. The license log file will depend on the application. Some common log files:
You can also confirm the vendor port using license logs. For FLEXlm, look for lines like this:
00:00:00 (lmgrd) FlexNet Licensing (<license manager version>) started on <hostname> 00:00:00 (lmgrd) lmgrd tcp-port <license server port> 00:00:00 (lmgrd) Started <vendor daemon> (pid <pid>) 00:00:00 (lmgrd) <vendor daemon> using TCP-port <vendor port>
And for RLM, look for lines like this:
1/1 00:00 (rlm) License server started on <hostname> 1/1 00:00 (rlm) Using TCP/IP port <license server port> 1/1 00:00 (rlm) Starting ISV server <vendor daemon> on port <vendor port>
