Off-Premise License Server

Technical Details For Administrators

Some of these instructions may require an IT administrator. Please seek their help if anything isn’t clear or as expected

Our software uses an off-premise license server to activate remote keys.

To use the off-premise license server requires an internet connection to an off-site server hosted on our Azure platform

To facilitate this, any external connection firewalls will need to allow outbound connections to the off-premise license server

Create an outbound rule on any firewalls to enable access to the I.P. address 51.104.43.133

If your policy requires port level connection rules then set the rule to allow connections to port 8000

On-Premise License Server

Technical Details For Administrators

The license server is a windows service that runs on any Windows server within your organisation

It provides activation for ScanToPDF software using 2 different models, fixed model and concurrent model

ScanToPDF software that has been configured to use the license server for activation (using either of the 2 models above) will connect to the licensing server to request activation keys for the modules in use. The license server will then return an activation key to the software to activate it

In fixed model operation the keys are allocated on a first come first serve basis, until all activation keys have been issued by the server. At this point no more keys can be issued until some of the keys have been manually released using the Licensing Supervisor utility which is part of the Licensing Server software suite

In concurrent model operation the activation is only used when the software is active. As soon as the software is closed the activation key is returned to a pool of keys, ready for another user
