GujChat is completely multi-lingual and can be installed under any Servlet API 2.2 (or newer) compliant servlet container.

Gnowsys: GNOWSYS is an acronym for "Gnowledge Networking and Organizing SYStem." It is a web based object oriented database server with each object provided by an unique URL. GNOWSYS is a tool to construct and store persistently a Gnowledge Base (GB). The GB consists of the following three groups of constructor classes (system and temporal classes under development): PredicateGroup: relationType, relation, functionType, function Object Group: metaType, class, object (with provision to have classes and objects of declarative, procedural, encapsulated, temporal etc.) Structure Group: systemType, system, flowType, flow, processType, process GNOWSYS indexes data and metadata of objects in a catalogue for faster queries. Optionally, data can remain anywhere on the Internet (only the metadata stays in the database). Surrogates of procedures (classes, functions, and system calls) can also be installed in the database as special objects. These procedures execute as web services, so users can design applications without writing program in any programming language by specifying the semantics of a program and mapping the elements of the program to the surrogates of procedures is sufficient for GNOWSYS to test the application design.

Gnu Hosting Helper: This package provides tools to manage many of the aspects of a hosting environment.It also provides a client utility to reduce the need for staff to perform tasks that a client needs such as managing email accounts.

It is, in essence, a general purpose proxy server, but especially suited for maintaining a cache of Debian or Gentoo packages.

Halberd: To cope with heavy traffic loads, web site administrators often install load balancer devices. These machines hide (possibly) many real web servers behind a virtual IP. They receive HTTP requests and redirect them to the real web servers in order to share the traffic between them. Halberd is a tool aimed at discovering real servers behind virtual IPs.

HealthBox: HealthBox is a convenient way to manage health information. Instead of each app having to record inforamtion within it's own ecosystem, HealthBox creates a place for developers to centralize health information. Say you have a program that records your steps, one that monitors work outs, and a third program to track your nutrient intake. Typically, if you wanted to access your information, you'd have to use each respective service's interface. With HealthBox, those developers would be able to store all the information in one place, making it much easier for you to compare different health metrics, and share information between services.

The clients show connection time and throughput statistics. The package supports different connection types, such as analog modems, ISDN, or even cable modems and ADSL devices.

Lingerd: Lingerd is a daemon designed to properly close network connections from an HTTP server (ie Apache). This frees the server from doing the boring but time-consuming job of "lingering closes", and lets each process go on to the next connection immediately. As a result, Apache needs fewer processes to handle high loads. This saves memory, reduces kernel contention, and makes Apache more scalable.

LiquidFeedback: LiquidFeedback is an open-source software, powering internet platforms for surveys, proposition development and decision making. LiquidFeedback is an independent open source project.

Two SMTP back-ends are provided. One delivers mail to qmail-queue, mimicking most of the behavior of qmail-smtpd, with the addition of support for SMTP AUTH. The other rejects all SMTP commands if $SMTPREJECT is set, and execs its command line otherwise (in order to run the above program).

Mandos: The Mandos system allows computers to have encrypted root file systems and at the same time be capable of remote and/or unattended reboots. WouldnÃ¢â¬â¢t it be great if you could have the security of encrypted root file systems and still have servers that could boot up automatically if there was a short power outage while you were asleep? That you could reboot at will, without having someone run over to the server to type in the password? Well, with Mandos, you (almost) can! The gain in convenience will only be offset by a small loss in security. The setup is as follows: The server will still have its encrypted root file system. The password to this file system will be stored on another computer (henceforth known as the Mandos server) on the same local network. The password will *not* be stored in plaintext, but encrypted with OpenPGP. To decrypt this password, a key is needed. This key (the Mandos client key) will not be stored there, but back on the original server (henceforth known as the Mandos client) in the initial RAM disk image. Oh, and all network Mandos client/server communications will be encrypted, using TLS (SSL).

MaraDNS: 'MaraDNS' is a fully functional DNS server supporting authoritative DNS, recursive DNS, and caching DNS. It is intended for environments where a DNS server must be secure and where the server must use the absolute minimum number of resources possible.

Pen: Pen is a load balancer for "simple" TCP-based protocols such as HTTP or SMTP. It allows several servers to appear as one to the outside. It automatically detects servers that are down and distributes clients among the available server for high availability and scalable performance. The load balancing algorithm tracks clients and tries to send them back to the server they visited the last time. The client table has slots (default 2048, settable through command-line arguments). When the table is full, the least recently used one is discarded to make room for the new one. This is superior to a simple round-robin algorithm, which sends a client that connects repeatedly to different servers. This breaks applications including most modern web applications) that maintain state between server connections.

Tux also provide an interface to develop user space extensions. tux_perl works as an user space module of Tux, and interprets Perl scripts to provide dynamic contents. Tux is embedded into Linux kernel, so tux_perl only work with Linux. Perl interpreter is also necessary. GCC compilers is required to build some C libraries.

VNC Reflector: VNC Reflector is a specialized VNC server which acts as a proxy between a real VNC server (a host) and a number of VNC clients. It was designed to work efficiently with large number of clients. It can switch between different hosts on the fly, preserving client connections. It supports reverse host-to-reflector connections and can save host sessions on disk.

Vaultwarden

Vaultwarden is an unofficial Bitwarden compatible server written in Rust, formerly known as bitwarden_rs. It is compatible with upstream Bitwarden clients. It is a libre password manager that stores sensitive information such as website credentials in an encrypted vault.

Features

Full implementation of Bitwarden API is provided including:

Organizations support
Attachments
Vault API support
Serving the static files for Vault interface
Website icons API
Authenticator and U2F support
YubiKey and Duo support

VideoCache: VideoCache is a squid url rewriter plugin written in Python to facilitate youtube, metacafe, dailymotion, google, vimeo, redtube, xtube, youporn, msn soapbox, tube8, tvuol.uol.com.br, blip.tv, break.com videos and wrzuta.pl audio caching. It can cache videos from various websites in a separate directory (other than squid cache), in a browsable fashion and can serve the subsequent requests from the cache. It helps in saving bandwidth and loading time of the videos. VideoCache is currently used by many ISPs.

Vlogger: 'vlogger' is a logger daemon for Apache. It will accept piped logfile input, split it according to its corresponding virtual host (using a file cache to avoid resource limitations), and write it to disk. It automatically rotates all files and tracks them using timestamps. It is intended as a replacement for cronolog or httplog.

VncSelector: VncSelector lets users manage currently active VNC server sessions. This can be particularly useful in a thin client situation.

W3perl: Web logfile analyser written in Perl. All major Web stats are available (referer, agent, session, error, etc.). Users can customise reports via configuration files, and an administration interface control is available.

WACS: WACS is a web based application for the management of and access to adult material (images, video clips) from a Linux-based server running the LAMP stack on a domestic local area network. The client machines can be pretty much anything running a reasonably modern web browser. WACS provides topic and model based indexing, advanced searching, new additions lists, and many other retrieval features. WACS also includes extensive download features allowing your collection of your favourite models' works to be right up to date.

Web-FTP: Web-FTP provides quick, easy, and (with an SSL-enhanced Web server) more secure access to your FTP server. Designed with file management in mind, it supports uploads, downloads, and all the usual tasks. No spool directories are used; file transfers are relayed directly from the server to the client and vice versa. Multiple file and recursive directory downloads are supported by generating a tar file on the fly. It can also serve as an FTP client, allowing FTP access to clients behind a firewall. You may view and edit files as well. Web-FTP also has rudimentary CryptoCard support, for CryptoCard protected servers.

Webfs: 'webfs' is a simple http server for purely static content. You can use it to serve the content of a ftp server via http for example. It is also nice to export files quickly by starting a http server in a few seconds, without editing a config file first. There is some sendfile emulation code which uses read()+write() and a userland bounce buffer. This lets you compile and use webfs on systems without sendfile(). From version 1.14 on, limited CGI support is available (GET requests only); from version 1.18 on, optional SSL support is available.

Webpublish: WebPublish manages the work associated with publishing a local copy of a website to one or more remote servers via FTP, letting website developers concentrate on content. WebPublish knows when changes or additions have been made locally, and only transfers to a server the files and directories that have been added or changed locally. It also knows when files and directories on the server are no longer a part of a local copy, and can be used to to remove those files and directories. It also lets users exclude files and directories from being transferred to or removed from a server.
