AFD is a program to automatically distribute files either locally or to remote hosts. The files are distributed by using FTP or SMTP, and can be sent in parallel and with priority. It provides a GUI to monitor and control the distribution and extensive logging of all activities.
AxY FTP (formerly known as WXftp) is an easy-to-use FTP client for the X Window System. Features include an intuitive user interface (Motif and GTK+), side-by-side local and remote directory listings, simple and convenient session manager, on-line help, progress bar, passive and non-passive transfers, and more.
BetaFTPD is a single-threaded FTP daemon. The single-threadedness makes it faster than most other FTP daemons (contrary to common belief), and makes it extremely light on memory. Although it lacks a few functions (which you probably won't miss), the current version is very small and has a decent amount of functionality. BetaFTPD is built on the concept of heavy code reuse, which should hopefully make it easier for other programmers to contribute.
bftpd is a very configurable Linux FTP server which can do chroot without special configuration or directory preparation. It will work out-of-the-box with almost no configuration required, and works on all Unix variants tested. Most FTP commands are supported, and user authentication is done via passwd/shadow or PAM. tar/gzip on-the-fly is supported.
The ECLiPt Mirroring Tool is a full featured FTP mirror script written in Python. It supports nice config files, many features for controlling the mirror (include, exclude of files, special watermarks for deleting files, download just the latest version of some program), as well as producing nice HTML output.
EFTP is a backwards-compatible server and client which implement an extension to the FTP protocol. The extension provides protocol-level support for directory recursion and compression over a persistent connection. As would be expected, for the extension to be used, the extended client must be connecting to an extended server.
The file check daemon monitors files according to rules defined in configuration files. When a file is considered stable (due to its age, presence of a flag file, etc.) then it gets copied to a new location. Rotating backups of the destination file can be made and owner, group and permissions can be specified for the destination. Some examples of where this utility has been found to be useful are: Moving files out of an incoming FTP directory in a timely manner. Moving files uploaded to a web server into directories with different user/group. This lets the administrator run the web server as a non-root user and accept uploads using web server based authentication and then move the files to a more secure area after the transfer. The details of how to determine whether a file is stable and what to do with it once it is are defined in a "Filespec" configuration file. There is a separate filespec for each file that will be monitored which means that each file can have unique behavior associated with it.
