Protection Against License Manipulation

8.6 Protection Against License Manipulation
HiPath License Management guarantees protection against any manipulation of the licenses.
This includes, for example
editing a license file
●
changing the system time
●
multiple read-in of licenses
●
extension of the grace period
●
When a Grace Period Configuration File (GPCF) is created, a flag is set in the system CDB
and the Customer License Agent (CLA) to indicate that a GPCF file was created. This en-
sures that the 30-day period cannot be extended and the GPCF file cannot be regenerated.
To guarantee the security and consistency of the product licenses generated, chang-
>
es to the system time on the PC of an installed Customer License Agent (CLA) must
not exceed one day.
If the system clock is reset by more than one day, the Customer License Agent stops
functioning and cannot be reactivated. The full functionality of the CLA on this PC
can only be restored by means of a repair or a reinstallation (see the License Agent
Installation Manual).
