Tools not Applicable to the VE License Server

...

Any Sentinel/Gemalto-specific license tools provided with the emulator installation are not applicable to the VE license server configuration.

Sentinel/Gemalto-specific tools and configuration options on Charon-SSP:

In Charon-SSP

...

, the Sentinel/Gemalto-specific license tools and configuration options are available when installing the management packages for the VE-capable Charon-SSP emulator packages. These tools and options are in particular the following:

  • HASP Viewer, HASP Updater, and HASP Manager in the Tools > HASP Tools menu of the Charon Manager
  • The Regular and Backup License parameter in the emulator license configuration section
  • The command-line tools in /opt/charon-agent/ssp-agent/utils/license

The above tools cannot be used for managing Charon-SSP VE licenses. Please ignore them if you have a VE license.

Actions that can Invalidate a VE License

pagebreak
Excerpt
class

A For cloud deployments: if supported by the cloud provider, the VE license server in a supported cloud environment instance can be moved to a different subnet or zone in the same virtual private cloud environment. , as long as the original instance can be moved.

It is also possible to backup and restore (to the same instance) the license server data. Please note: it is not possible to use such a backup to revert to a previous license version.

However, the following actions will invalidate the license:

Changing the number of CPU cores of the license server system.
  1. All supported environments:
    • Copying the license server data to a different instance.
    • Seriously damaging the root filesystem of the license server system.
    • Re-installing the license server system
Div
    • .
    • Copying the virtual machine on which the license server runs. This includes cloning a virtual machine, or recovering a backup into a new virtual machine.
    • Changing the number of CPU cores of the license server system.
  2. VMware environments:
    • Restrictions from point 1 above. 
    • If the license server is bound to the ESXi host: using vMotion on the VM in which the VE license server runs
    • Changes to the API interface of the ESXi host or vCenter Server
    • The license can become temporarily unavailable if the user credentials or address information recorded by esxi_bind are changed. In this case, esxi_bind must be run again to define the correct user credentials and address information.


Starting and Stopping the License Server

Please note: In versions before 1.0.17, the license server can only be started if a valid license is installed.

...

  • Starting the license server:     # systemctl start licensed
  • Stopping the license server:   # systemctl stop licensed
  • Restarting the license server: # systemctl restart licensed

The licensed service logs information to its log file in /opt/license-server/log/license.log and to journalctl.

Primary and Backup License Server

General Information

Charon -SSP emulators for VE licenses supports support a backup license server to ensure service continuity should the primary backup license server become temporarily unavailable. Backup licenses are typically limited to a certain number of emulator runtime hours.

The example below shows the output of such a time-limited license:

The above sample is a backup license with 100 hours of emulator runtime. The remaining hours can be checked via the web interface.

Backup License Server Operation

Should the primary license server become unavailable, the emulator tries to connect to the backup license server. If this succeeds, the emulator continues to run without interruption. If no connection to a valid license can be established within 2 hours after the loss of the license has been detected, the emulator will stop. The grace period is defined on the license.

Please note: If you do not have a valid backup license and the primary license server is unavailable for more than 2 hoursthe grace period, make sure to shut down the Solaris guest operating system cleanly before the end of the grace period. Failure to do so may cause data loss or corruption.

If the primary license server becomes available again after the emulator has switched to the backup server, the emulator will automatically switch back to the primary server to avoid unnecessary depletion of the backup license runtime hours in VE license server mode.

Log Files

Log files provide important information about the operation of the license server and the Charon -SSP emulator software. In case of problems, this is the first place to check.

License Server Log File

Log File Location

The license License server log file is stored under /opt/license-server/license_logThe log file is called log/license.log.

At every license server start, a new version of the log file is created and the previous file is rotated to license.log.1. Other existing versions are rotated accordingly.

Charon-SSP Emulator Log Files

Please note: The log file path can be changed by the user to a non-default value.

Please note: The output shows a 2 hour grace period. The grace - period . This is applicable to Charon-SSP versions implementation changed several times. In VE versions before version 4.1.21 and later. In earlier versions , the grace - period was 24 hours. This is no longer needed because a backup license server can now be configured (since Charon-SSP version It was shortened to two hours after the introduction of the backup license server feature in 4.1.19). Since version 1.1.12, the grace period is determined by the corresponding license parameter. If a valid license has not become available before the end of the grace period, the emulator will be stopped.
