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.
F*EX (Frams' Fast File EXchange) is a Web based service for sending very big files from one person to another. The sender uploads the file to the F*EX server and the recipient automatically gets a notification email with a download URL. Files are automatically deleted after download or an expiration date. The recipient and sender only need an email program and a Web browser. Sending to multiple recipients needs storage on the server only once. In contrast with other file transfer services, it has no file size limits at all and comes with shell tools for scripting up/downloading.
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.
Nephthys provides a Web interface to create file-sharing "buckets", through which data can be shared. Nephthys handles the buckets in the local filesystem of the server. Access and data transfer is made via FTP and WebDAV. Nephthys itself does not provide the access protocol, but relies on well known projects like Apache HTTPD (WebDAV) and ProFTPD (FTP).
The aim of the PicoForge project (previously known as PicoLibre) is to provide a set of high level libre software applications that are well integrated in order to provide a collaborative "forge". It makes it easy to deploy a collaborative work platform for developing software or hosting other collaborative activities. Having started (as PicoLibre) in an educational context, PicoForge is now a quite generic platform, comparable (but sometimes less advanced) to other *-Forge software platforms. It groups several high-level applications like phpGroupware, Sympa, TWiki, Subversion, and CVS.
UDPCast allows to send data simultaneously to many destinations on a local net. This can for instance be used to install entire classrooms of PCs at once. The advantage over using other methods (nfs, ftp, whatever) is that udpcast uses Ethernet's multicast abilities: it won't take longer to install 15 machines than it would to install 2. The tool comes with a busybox bootdisk for easy loading of the tool. However, udpcast can also be started from the command line of an already installed system, and can be used for other purposes than just system installation.
Collaba is a multimedia collaboration and communication server built to provide digital workspaces to virtual educational, corporate, and other communities. It features secure email (Web, POP3/SMTP, crypto, and anti-spam), online forums (Web, RSS, NNTP, and podcast), blogs (Web, RSS, podcast), multimedia chat (text, multimedia panel, etc.), personal and group calendering, address books, bookmarks, an online Web page editor, file services and CMS (Web, WebDAV, FTP, SMB, CIFS, anvi-virus API, and ClamAV support), digital portfolio, dynamic news board, directory access, support for multiple independent communities on one server, Single-Sign-On features (built-in support for LDAP, CAS 2.0, JAAS, SMTP-Auth and more, powerful developer API), full online server management, anti-spam (RBL and filters), anti-virus support, centralized management with LDAP directories, Web publishing of personal, group or general web sites, developer APIs, and much more.
NASLite is a Network Attached Storage (NAS) server operating system designed to transform a basic computer into a dedicated file server. Utilizing highly optimized versions of Samba, uCLibc, BusyBox, and various other Linux tools, it provides SMB/CIFS, FTP, or NFS filesystem support. It accommodates multiple client OSes: Windows, Mac OS X, and Linux. NASLite offers SMART disk monitoring and large file support, and is incredibly easy to install and administer.
Oliver (formerly "WebShare") is a PHP-based FTP front-end, released under the GPL. It allows people to access files normally only available via FTP, effectively providing users with a complete Web-based file management system that, if SSL is enabled on the Web server, uses a single secure connection. This makes it far simpler to use through a firewall. At present, Oliver has only been tested with ProFTPd and PureFTPd but it should work with many others.
Event Horizon (EVH) is a Web-based application which facilitates the secure transfer of files. Originally designed to replace FTP transfers, EVH currently allows uploads via HTTP and can also handle files uploaded via FTP. All file uploads are assigned an expiration period, after which the file is permanently removed from the system. This allows for automatic cleanup as well, keeping the underlying filesystem in tip-top shape.
