Each computer requires a separate licence, called a node licence. The node licence is only valid in conjunction with a specific Xentara licence. In order to issue a node licence, embedded ocean GmbH needs a licence ID for the computer.

Generating a Licence ID

In order to issue a node licence for a particular computer, embedded ocean GmbH needs a licence ID for the computer. The licence ID must be generated by running the Xentara licence ID generation tool on the target computer. Under Linux, this tool is called xentara-licence-id, and is located under /usr/bin. Under Windows, the tool is called XentaraLicenceId.exe and is located under App in the installation directory.

The generated licence ID will be printed to the standard output, which is normally the terminal or command window where the command was run. You can write the licence ID to a file by redirecting the standard output in the usual way using “>”. To redirect the standard output to a file called “myNodeLicence.txt”, for example by typing xentara-licence-id > myNodeLicence.txt under Linux, or C:\Program Files\Xentara\App\XentaraLicenceId > myNodeLicence.txt under Windows.

Under Windows, you can also just double-click on XentaraLicenceId.exe, or select “Xentara licence ID generation tool” from the Windows Start Menu, to show the licence key. Since XentaraLicenceId.exe is a so called “console application”, the licence key will be shown in a Windows console window. Text in Windows console windows can be selected using the mouse, and copied by pressing Enter. If selecting text with the mouse does not work, you may have to open the console’s menu by clicking on the icon in the title bar, and choose “Mark” from the “Edit” sub menu, as shown here:

You can also run Xentara itself to output the computer’s licence ID. If Xentara does not find a valid licence, it will print the licence ID to the standard output.
