Using the License Server
In order to avoid having to activate a callas software product, you can use a reference to a running License Server in the call to that product. The License Server needs to be activated, it needs to be running and it needs to have valid cartridges installed.
The "licenseserver" option points the callas software product to the License Server so it can get permission to run your call.
./pdfToolbox --licenseserver="220.127.116.11:1444" <other command-line parameters>
The parameter specifies the IP address of the License Server you want to use. Optionally, this can be followed with a colon and a port number. If you use the default License Server port (1400), the port doesn't have to be specified.
