AnomicFTPD is an RFC959-compliant FTP server with OS- independent user and group management. Active and passive modes, non-root mode, and anonymous and/or read-only modes are supported. A built-in client IP filter acts as a firewall and provides additional access limitation. The server has no online interface; attributes, groups, and user accounts are configured through text files. The protocol/ format-unspecified LIST command produces output that is compatible with most FTP clients, including common Web browsers in FTP mode.
afick is another file integrity checker, designed to be fast and fully portable between Unix and Windows platforms. It works by first creating a database that represents a snapshot of the most essential parts of your computer system. You can then run the script to discover all modifications made since the snapshot was taken (i.e. files added, changed, or removed). The configuration syntax is very close to that of aide or tripwire, and a graphical interface is provided.
