fileServersNG will work with community or enterprise versions of Alfresco, currently there is a project that will build the fileServersNG AMP for Alfresco v4.x or v5.x, we should have a version for Alfresco v6.x in the near future.
There is a Docker image available with an Alfresco 5.2 community release with the fileServersNG subsystem deployed, there's more information on the website at http://www.filesys.org, there are Wiki documents with details of how to build/deploy the fileServersNG subsystem, and how to use the Docker image here - http://www.filesys.org/wiki/
The fileServersNG subsystem uses the JFileServer code, a fork of the Alfresco-JLAN code, with an optional Enterprise add-on that provides the SMB2/SMB3 support (that works with community or enterprise versions of Alfresco).
