Description
Objective: The LAS Supportability Tool (LASSupportabilityTool.exe) helps administrators validate that their environment is ready for Citrix Cloud registration by checking network connectivity, supported ciphers, and current registration status.
Tool Capabilities:
-
Connectivity Validation: Ensures the License Server can successfully reach the LAS cloud service.
-
Cipher Validation: Verifies that at least one of the strictly required secure ciphers is enabled on the OS.
-
Registration Status: Checks the current Citrix Cloud registration status of the License Server.
-
Proxy Support: Tests connectivity through a specified HTTP proxy server.
Command-Line Options: Open a Command Prompt (run as Administrator for registration checks) and navigate to the directory where the tool is extracted.
-
--help: Show the help menu and exit. -
--proxyurl <url>: Use the specified HTTP proxy for connectivity checks. -
--installdir <path>: Specify a custom Citrix Licensing installation directory. (Default:C:\Program Files (x86)\Citrix\Licensing\) -
--validateciphers: Validate if at least one of the required ciphers is enabled on this system. Run this ONLY from where the product is installed. -
--checkregistration: Validate the Citrix Cloud Registration Status of this License Server. (Needs elevated mode execution. Ignore the result if both License Server and CC-UI report successful registration). -
--ccid: Optional input used with--checkregistrationto specify your Citrix Cloud ID.
Allowed Ciphers Checked (via --validateciphers):
-
ECDHE-ECDSA-AES256-GCM-SHA384 -
ECDHE-RSA-AES256-GCM-SHA384 -
ECDHE-ECDSA-CHACHA20-POLY1305 -
ECDHE-RSA-CHACHA20-POLY1305 -
ECDHE-ECDSA-AES128-GCM-SHA256 -
ECDHE-RSA-AES128-GCM-SHA256
Usage Examples:
-
Standard check:
LASSupportabilityTool.exe -
Check via proxy:
LASSupportabilityTool.exe --proxyurl http://proxyserver:8080 -
Check with custom install path:
LASSupportabilityTool.exe --installdir "D:\Citrix\Licensing" -
Check registration status:
LASSupportabilityTool.exe --checkregistration -
Check registration with proxy/CCID: *
LASSupportabilityTool.exe --checkregistration --proxyurl http://proxyserver:8080-
LASSupportabilityTool.exe --checkregistration --ccid "myccid"
-
-
Validate ciphers:
LASSupportabilityTool.exe --validateciphers
