aria2 is a utility for downloading files. The supported protocols are HTTP(S), FTP, BitTorrent, and Metalink. It has a powerful segmented downloading ability, downloading a file from multiple sources and multiple protocols and utilizing your download bandwidth to the maximum. It supports downloading a file from HTTP(S)/FTP and BitTorrent at the same time, while the data downloaded from HTTP(S)/FTP is uploaded to the BitTorrent swarm. Using Metalink's chunk checksums, aria2 automatically validates chunks of data while downloading a file like BitTorrent.
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.
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.
BSDftpd-ssl is a secure and easy-to-use FTP server that supports industry standard TLS/SSL encryption and authentication for whole FTP sessions and data transfers. This implementation supports both the original FTP protocol and the RFC2228-compliant TLS/SSL enhancement. The package contains the secure FTP server (named "ftpd") and a command line TLS/SSL-aware FTP client (named "ftps"). The server's features include logging of transfers, changing of a session root (known as "chroot"), and virtual host support.
gFTP is a free multithreaded file transfer client for *NIX based machines running X11R6 or later. It has text and GTK+ 1.2/2.x interfaces and supports the FTP, FTPS (control connection only), HTTP, HTTPS, FSP, and SSH protocols and has FTP and HTTP proxy server support. It supports UNIX, EPLF, Novell, MacOS, VMS, MVS, and NT (DOS) style directory listings, and has a bookmarks menu that allows you to quickly connect to remote sites. The code is fully internationalized and there are currently 45 translations available.
TCL2FTP is an extension library for Tcl scripts which allows Tcl programs to perform FTP client and gateway actions. It fully supports the FTP/FXP protocols, is ready for use with SSL/TLS, and is compatible with glFTPd. It can run simple FTP commands, and it supports 25 simultaneous FTP sessions.
wzdftpd is designed to be a small, efficient, and highly modular/configurable FTP server for various platforms including Linux and Windows. The server is RFC compliant, multi-threaded and can be configured entirely online using SITE commands. You can write your own extensions to the server in your choice of language, extending on existing MySQL, PostgreSQL, SQLite, Tcl, Perl, PAM, and SFV plugins. Features include IPv6, TLS/SSL, UTF8, ACLs, VFS, events, scripting, plugins, job scheduler, bandwidth limitations, credits/sections, group administration, and customizable logging.
OpenVISP Admin is a fork of Postfix Admin. Its aim is to provide a unique ISP tool as a Web panel for end users, postmasters, and site administrator to manage their data. It allows site administrators to update amavisd-new values, spam-assassin values, greylisting, domains checks, and sender verification. It can also provide datacenter admins with a central point of access, by having APC Masterswitch configuration and access, hosting access requests, and PPTP access and statistics views.
