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.
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.
Aftpd is an FTP server for anonymous access designed for Unix-like operating systems. It uses an asynchronous model of connection processing and provides service for all users within a single process; can use multiple threads to run more efficiently on multi-core systems, with each thread serving multiple clients simultaneously; uses effective mechanisms of transferring files, minimizing copying of data in RAM (sendfile or a combination of the system calls mmap/writev); uses effective event notification schemes (kqueue on FreeBSD and epoll on Linux); uses poll or select in older systems; and supports IPv6. For safety, it works as an unprivileged user and uses chroot.
AntFlow builds upon Apache Ant to provide a new approach to simplifying system automation that uses pipelines of hot folders chained together to perform a given task. Using XML, it associates an automated task such as data transfer, encryption, or XML processing with a directory on the local system. Whenever a file is copied or written into the hot folder, the associated task is executed and the file is moved to the next hot folder in the pipeline for further processing.
AnyClient is a platform-independent file transfer application that supports all major file transfer protocols including FTP/S, SFTP, and WebDAV/S. It is available both as a Web-based service requiring no software installation, and as a downloadable application that you can install locally.
