VE License Server

The Charon-SSP version, Any Sentinel/Gemalto-specific license tools are available when installing the management packages for the BYOL-capable Charon-SSP emulator packages. These tools are in particular the following:provided with the emulator installation are not applicable to the VE license server configuration.

Sentinel/Gemalto-specific tools and configuration options in Charon emulator kits:

In Charon emulator kits, the Sentinel/Gemalto-specific license tools and configuration options are available when installing the complete emulator packages. These tools and options are in particular the following:

  • Charon-SSP:
    • 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

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

Actions that can Invalidate a Cloud BYOL License

Excerpt

A cloud BYOL license server in a supported cloud environment can be moved to a different subnet or zone in the same virtual private cloud environment. It is also possible to backup and restore (to the same instance) the license server data. However, the following actions will invalidate the license:

  • Changing the number of CPU cores of the license server system.
  • 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

  • Charon-PAR:
    • The command-line tools in /opt/charon/bin (including the update tool hasp_update, and the license viewer and C2V creation tool hasp_srm_view)
    • The license_id configuration parameter is not supported. To choose a specific product section, the passphrase of the section is used.

The above tools and commands cannot be used for managing VE licenses. Please ignore them if you have a VE license.

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 / Peer Servers

General Information

Charon -SSP emulators for BYOL VE licenses support a backup license server to ensure service continuity should the primary backup license server become temporarily unavailable. Backup The primary/backup servers in general VE license mode operate differently from the peer servers of AutoVE mode:

  • For general VE license mode, backup licenses are typically limited to a certain number of emulator runtime hours.

...

The example below shows the output of such a license:

Note the parameters K_TYPE=COUNTDOWN and K_EXPIRED=100. They indicate that this is a backup license with 100 hours of emulator runtime.

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, the emulator will stop.

Please note: If you do not have a valid backup license and the primary license server is unavailable for more than 2 hours, 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.

Log Files

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

License Server Log File

Log File Location

The license server log file is stored under /opt/license-server/license_log

The log file is called 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.

  • The backup license server is only used for failover if the primary license server fails in order not to deplete the available runtime hours unnecessarily.
  • For AutoVE mode, the two license servers act as peers between which the client database is synchronized. The total number of instances available on both servers determines the number of Charon host cloud instances that can be licensed from the license server pair. Each instance can connect to either of the two servers. However, if one of the peers fails and there are not enough available instances on the second peer, there is no backup for an instance trying to fail over to the second  peer due to failure of its primary server - and the emulators running on this instance will fail. The license on the server designated as backup server can be a countdown license (specified number of runtime hours) or a normal license.

The example below shows the output of 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 the grace period, after the loss of the license has been detected, the emulator will stop. The grace period is defined on the license. Check the license content for the actual value configured (default for new licenses is 24 hours, but the actual configuration may be different).

Please note: If you do not have a valid backup license and the primary license server is unavailable for more than the grace period, make sure to shut down the 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.

Charon-SSP Emulator Log Files

Log File Location

The default emulator log file location is /opt/charon-agent/ssp-agent/ssp/<architecture/<vm-name>/.

  • <architecture> can be sun-4m, sun-4u, or sun-4v.
  • <vm-name> is the name of the emulated SPARC system.

The log file is called <vm-name>.log. At every emulator start, a new version of the log file is created and the previous file is rotated to <vm-name>.log.1. Other existing versions are rotated accordingly. The number of retained files is determined by the log configuration of the emulated SPARC system.

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