JFileServer is a Java based file server that currently supports the SMB/CIFS, FTP/FTPS and NFS protocols. A virtual filesystem interface allows custom filesystems to be implemented, with a database filesystem framework that makes it easy to use a database to store the filesystem metadata, and optionally the file data.
The file server is highly scalable using asynchronous I/O, thread pools and memory pools to optimise the throughput. The server may be clustered for additional scalability based on the Hazelcast cluster technology.
An Enterprise add-on module adds support for SMBv2 (higher performance) and SMBv3 (full encryption).
The JFileServer code originally started out as the JLAN Server, the first version being released by Starlasoft back in the late 1990's with basic SMB1 support. As development of the JLAN Server continued, SMB1 support was enhanced, and FTP and NFS support were added, along with the database filesystem framework and smart caching.
In 2007 Alfresco Software bought the rights to the JLAN Server code rebranding it as Alfresco-JLAN, and releasing the code as open source. Development continued with the addition of support for NTLMv2 and Kerberos enterprise authentication, scaleability enhancements using NIO, thread pools and memory pools, plus cluster support using Hazelcast, and FTPS support.
In recent years no new development has been done on the Alfresco-JLAN code.
At the beginning of 2018 we forked the Alfresco-JLAN code to create the JFileServer project to bring the source code up to date, and continue development of the file server.
The core JFileServer library and components such as the database filesystem implementations are licensed under the same GNU LGPL v3.0 license as the original Alfresco-JLAN code.
The JFileServer code uses features of JDK version 11 onwards.
Pre-configured setups of the core JFileServer and various database fileserver implementations are available as Docker images which can either be used as they are or used as the starting point for your own configurations.
For a list of the available Docker images see https://hub.docker.com/r/filesysorg/.

Additional information and documentation will be added there in the near future.
