(v13) Sentinel LDK notes

This page applies to Harlequin v13.1r0 and later; both Harlequin Core and Harlequin MultiRIP. Applies only to RIPs using LDK security.

When you install a new RIP using the LDK and you activate your product key, the RIP runs.

If you uninstall the RIP and remove the LDK runtime and then re-install the RIP and LDK runtime using the “skip this step...” option when prompted to enter the key, the RIP should run because the SL key should still be present.

If, however, the RIP does not run, claiming that no licenses are available, you should check that the LDK runtime is running. To do this on Windows, right-click Computer and select Manage. Select Services and Applications in the left window, followed by double-clicking Services in the right window. This displays all the available services. Scroll down and select Sentinel LDK License Manager followed by Start.

When the service is running on Windows, Restart is displayed.

On Linux, the LDK daemons can be managed using systemd or sysvinit (whichever is running on your system).

To check their current status, use:

sudo systemctl is-active aksusbd.service sudo systemctl is-active hasplmd.service

or

sudo /etc/init.d/aksusbd status

To start the LDK daemons:

sudo systemctl start aksusbd.service sudo systemctl start hasplmd.service

or

sudo /etc/init.d/aksusbd start

and the equivalent command(s) to stop the daemons.

 The Admin Control Center is only available when the Linux daemon is running.

Generally, if you have a problem with the RIP not starting and you have already activated your product key, restart the Sentinel LDK License Manager service or LDK daemons.

On macOS, we recommend that you check that the LDK runtime is running using:

sudo launchctl list | grep com.aladdin

which should report something like:

  58 0 com.aladdin.hasplmd
  96 0 com.aladdin.aksusbd

To start the daemons use:

  sudo launchct1
  load /Library/LaunchDaemons/com.aladdin.hasplmd.plist
  sudo launchctl
  load /Library/LaunchDaemons/com.aladdin.aksusbd.plist

To stop the daemons use:

  sudo launchctl
  unload /Library/LaunchDaemons/com.aladdin.hasplmd.plist sudo launchctl
  unload /Library/LaunchDaemons/com.aladdin.aksusbd.plist
