Locating LUSAS network license server from a client PC
(Sentinel RMS License Manager - V15 and V14 back to and including V14.2)

For detailed information see the "Installation Guide" on the LUSAS installation folder. Assuming you have installed LUSAS on the C drive this file is located at: C:\LUSAS15*\Installation Guide.pdf

Once the LUSAS license has been added to the server, all client computers need to be told about the license server. On each client computer in turn, start the LUSAS Configuration Utility by going to:

Start> All Programs> LUSAS 15.x for Windows> Tools> Configuration Utility

on the licensing tab choose Network license, and press Search for licenses. There will be a pause whilst LUSAS scans your network for servers. Select the chosen server from the list. If multiple LUSAS licenses are available on that server, it will also be necessary to choose one of these.

If there is a valid license server the Configuration Utility should find it. However if this fails (a likely problem for some laptops) with the error "Sentinel RMS Development Kit: Error [17]: probably no servers are running on this subnet" which is explained further below.


License key-related error messages for network (floating) licenses

In V15 and also back to V14.6, on starting Modeller with a network license:

  "Error(s) occurred on validating Modeller key:[SENTINELLM,"HOSTNAME",#KeyID#]
  - Server "HOSTNAME" could not be found, for feature "LusasM_
#KeyID#". The network may be unavailable"

And/Or in V14.4 to V14.7 inclusive in a message box on starting Modeller:

   "No valid licences are available to LUSAS on this machine, licences may be added or made available to LUSAS via the configuration utility."

Or in the Solver Output file ".out" or echoed to the Text Output window in Modeller:

  ***ERROR*** No appropriate valid licenses found in file C:\LUSAS150\\fea.key - Consult your local distributor

Or in V14.2:

  "[SENTINELLM,"HOSTNAME",#KeyID#]: Error[5]: Cannot talk to the license server on host "HOSTNAME". Server not running??"

Causes & links to solutions 

This is a  means the specified license server is not visible to client or Sentinel RMS License Manager is not installed or not running on the server.

Check or try the following:

  1. Test the network connection between client PC and license server machine with a ping test

  2. Check if Sentinel RMS License Manager is running as a Service on the license server machine.

  3. Check if the license has been installed successfully.

  4. Security software or a firewall may be blocking access.

If still you have problems, please generate two licensing reports, one from the server computer, and one from the client and email these to Support for further assistance.

Solutions

Test the network connection between client PC and license server machine with a ping test

Open a command (DOS) window and try pinging the server by typing:

ping server name

This should return successful replies, if not try pinging the server’s IP address or full DNS name.

 

Check if Sentinel RMS License Manager is running as a Service

On the license server machine check if Sentinel RMS License Manager is running as a Service and it shows Started .

If you go to Control Panel > Administrator tools > Services (or Start>  Apps/All Apps> Services) you should see Sentinel RMS License Manager there and this should show "Started" as its Status. Otherwise go to its properties and "Start" it:

If the entry is not in services, then possibly the installation of Sentinel RMS License Manager has not been successful.  It may need to be uninstalled and reinstalled once again, noting any error or warning messages that occur during the installation.

 

Check that the license code text file has been installed successfully

Following successful installation of the license code file, the file "lservrc" should be found at: C:\Program Files\Common Files\SafeNet Sentinel\Sentinel RMS License Manager\WinNT\lservrc (No Extension) on the license server. If the license code file was installed successfully, this should be present and should contain the same information as provided in the license code file "network####.txt". If this file is not present or the information contained in it does not match the file "network####.txt", it suggests that the license has not been installed successfully.  In such case, try the following:

  1. Log on directly to the license server machine as the Administrator

  2. Use the Install Network License utility to add the license code text file:

    • If running Windows XP/2000/Vista/7/Server 2003/Server 2008, click Start> All Programs> LUSAS Server Utils> Install Network License 
    • If running Windows 8 or 64bit Server 2012, right-click on the main Start screen, choose All Apps and browse for the Install Network License utility
    • If running Windows 8.1, on the main Start screen, click on the Apps down arrow icon and browse for the Install Network License utility

 

“<none found>” on clicking “Search for servers” in the Configuration Utility

The license to be used can be set using the Configuration Utility on the client PC:

  • If running Windows XP/2000/Vista/7, click Start> All Programs> LUSAS 15.x for Windows> Tools> Configuration Utility
  • If running Windows 8, right-click on the main Start screen, choose All Apps and browse for the Configuration Utility
  • If running Windows 8.1, on the main Start screen, click on the Apps down arrow icon and browse for the Configuration Utility

From the Licensing tab if you click on "Add...", choose "Exisitng network license" and click "Next",  the license Server and Product can be selected. If this gives a message “<none found>” on clicking “Search for servers”, then please try the following:

  • Edit your FEA.KEY file in the LUSAS installation directory (eg. C:\LUSAS15X) on the client PC, using a basic text editor (say Notepad) such that the top line reads:

[SENTINELLM,###.###.#.#] ! Network key

  • Where the IP address should be entered in place of “###.###.#.#” or the license server name. 

[SENTINELLM,Servername] 

For example [SENTINELLM,Apollo] where Apollo is the LUSAS license server machine.

  • Save and close the fea.key file.

  • Start Configuration Utility again to pick the “Product” (i.e. the network license) that you want 

  • Press Apply

  • Test LUSAS

 

Security software or a firewall may be blocking access

If there is a firewall on the server or the client PC it may be restricting communication between the two. To check this, please see if temporarily disabling the firewall allows the client to find the license on the server. If it does, the applications/services that need to be allowed in the firewall settings are:

  1. lservnt.exe located in C:\Program Files\Common Files\SafeNet Sentinel\Sentinel RMS License Manager\WinNT on the license server

  2. LUSAS_M.exe LUSAS Modeller on the client PC

  3. You will also need to enable the port: 5093 UDP (for client-server communication)
