CrushFTP

CrushFTP is a FTP server that supports the following protocols: FTP, FTPS, SFTP, HTTP, HTTPS, WebDAV and WebDAV SSL. Additionally, although not a protocol, it has a web interface for end users to manage their files from a web browser. CrushFTP uses a GUI for administration, but also installs as a daemon on Mac OS X, Linux, Unix, and as a service in Windows. It supports multihoming, hot configuration changes, and has a GUI based user and group manager. The plugin architecture in CrushFTP allows for plugins to read users from SQL, LDAP, Active Directory, folders, and NetInfo. All settings are stored in XML files that can be edited directly, or with the CrushFTP GUI. If edited directly, CrushFTP will notice the modification date change and load the settings immediately without needing a server restart.
