DeepVacuum is a download manager based on the GNU wget command line tool. It includes a vast number of options to fine tune your downloads through both HTTP and FTP protocols. It makes it possible to download whole single pages, entire sites, FTP catalogs, link lists from a text file, and filtered types such as images.
DeleGate is a multi-purpose application level gateway or proxy server that mediates communication of various protocols, applying cache and conversion for mediated data, controlling access from clients, and routing toward servers. It translates protocols between clients and servers, converting between IPv4 and IPv6, applying SSL (TLS) to arbitrary protocols, merging several servers into a single server view with aliasing and filtering. It can be used as a simple origin server for some protocols (HTTP, FTP, and NNTP).
DrFTPD is an FTP server written in Java. It does not handle transfers in the same way that normal FTP servers do. Instead, it merges multiple FTP sites into one, creating a distributed FTP site/FTP cluster containing one master and many slaves/nodes. When a client wants to transfer a file from DrFTPD, DrFTPD finds the slave which has the file, and tells the appropriate slave to transfer the file instead of handling it itself. This allows huge gains in total bandwidth and disk capacity.
DocumentBurster is a tool for report distribution: split, merge, email, and FTP your reports. It has report delivery for Crystal Reports, SSRS Reporting Services, MS Access, Cognos, PeopleSoft, and SAP. It has report bursting for Pentaho, JasperReports, and BIRT. It can upload reports to MS SharePoint.
Domain Technologie Control (DTC) is a Web-based control panel for hosting that can delegate the task of creating subdomains, email, and FTP accounts to users for the domain names they own. It has support for many programs, including bind 8 and 9, MySQL, Apache, PHP 4, qmail, Postfix, Courier, Dovecot, ProFTPD, Webalizer, and mod-log-sql. It can also generate backup scripts, calculation scripts, and config files using a single system UID/GID, and monitor all traffic accounting per user and per service. It is fully skinnable and translated into several languages.
Dove is an application that facilitates the distribution of documents to a variety of destination types such as email, local files, FTP, FTPS, SFTP, TFTP, Samba servers, Windows network shared drives, and WebDAV servers. Being an abstraction layer over previously enumerated protocols, it allows sending of documents to email or to a WebDAV server with equal ease.
The Download Slave is a very flexible script which is controlled via eMail and stores files requested for downloading on the server's harddisk or sends them via eMail to the user who asked for them. Users are identified by their eMail address and a personal password, so only authorized users can use the service.
