unRAID includes the popular vsftpd FTP server.
The configuration of vsftp is currently very simple, and we hope to add additional sophistication in the future.
To enable FTP, you must enter a username. This user will have full read/write/delete access to the entire server, so use with caution. To disable FTP, clear the username. Note: please do not use username root since the root user is not part of the users group, this might cause problems in the future.
