Preventing FlexNet Embedded Local License Server from Broadcasting, UDP messages on port 1947

Preventing FlexNet Embedded Local License Server from Broadcasting, UDP messages on port 1947

Symptoms: 

Setting up a FlexNet Embedded local license server seems to be broadcasting, UDP messages on port 1947

Diagnosis:

HASP APIs, which were embedded as a third-party vendor in the FlexNet Embedded local license server, are broadcasting UDP messages on port 1947.

Solution:

Workaround for Windows platform:

  1. As a user with Administrator permissions, execute the attached BroadcastSearch.bat script on the machine that is running your FlexNet Embedded local license server.
  2. On this same machine, copy the vendor-ID-named file, hasp_61320.ini (created by the BroadcastSearch.bat script), to the system Network Service directory for Sentinel LDK. Use these steps:

           a. Copy the file from this location:

    C:\Users\xxxUser\AppData\Local\SafeNet Sentinel\Sentinel LDK\hasp_61320.ini

           b. Paste it in this location:

    C:\Windows\ServiceProfiles\NetworkService\AppData\Local\SafeNet Sentinel\Sentinel LDK

    Note: The file required for this solution is hasp_61320.ini, not hasplm.ini.  The content of hasp_61320.ini should include broadcastsearch = 0.

  3. Restart the FlexNet Embedded Local License Server

Workaround for Linux platform:

  1. As a user with root/sudo privileges, execute the attached BroadcastSearch.sh script. 
  2. Copy the vendor-ID-named file, hasp_61320.ini (created by the BroadcastSearch.bat script) to the following directory:

    /home/flexnetls/.hasplm/

  3. Restart the FlexNet Embedded Local License Server, which is invoked by user "flexnetls".

This solution has helped stop unnecessary broadcasting while still enabling product licensing.
