FreeNAS 8 is an excellent Network Attached Storage (NAS) solution and is ideal for providing Windows machines access to storage over the network. However, FreeNAS can do much more. The Common Internet File System (CIFS), which is used to share data with Windows machines, is only one part of the FreeNAS system. As well as services to share files with Linux (via NFS) and Mac OS X machines (via AFP), FreeNAS also offers FTP, TFTP and SSH services.
In this tutorial we will go beyond disks & sharing and configure the FTP, TFTP and SSH services. I will assume you have a FreeNAS system installed with at least one volume configured. For more information on installing FreeNAS and setting up volumes see my NAS Setup Guide.
