A subscription is what turns on Lockdown

Overview: A subscription is required to activate Lockdown on Root Lock by HeartSuite. The Dashboard shows subscription status alongside checklist progress and alerts.

Subscription

The Dashboard keeps Lockdown locked until the subscription on this host is active and the prior checklist items are complete. See Lockdown for the activation flow.

The subscription is a text file. One subscription can cover up to 9999 servers — at purchase, you specify how many servers it covers. You can purchase additional subscriptions if needed.

Dashboard

The Dashboard shows subscription status when it requires attention — an expired or missing subscription appears as a warning with a direct link to the upgrade page. A valid, active subscription shows nothing, so the absence of a warning confirms that the subscription is in good standing.

Activate on this host

After downloading the subscription file, copy it to each server it covers. Regardless of the original filename, it must be copied as HS_license.txt in the /.hs/sys directory.

# sudo cp MyCompany_HS_license.txt /.hs/sys/HS_license.txt

Register it using register_HS_license. The command requires the IP address of the Root Lock Activation Server and the port number (6121). Run the following command, replacing <ip> with the address from your activation email:

# sudo /.hs/sys/register_HS_license <ip> 6121

If activation succeeds, the program creates an activation key and displays a confirmation message; otherwise it displays an error message. You need to activate each server only once.

With your subscription active and the prior checklist items complete, proceed to Lockdown to activate Lockdown.
