[[Concept:Internet-application]]

Net Telnet Cisco: Net::Telnet::Cisco adds additional functionality to Net::Telnet that helps you automate Cisco router management and statistic gathering.

Net-check: The net-check package is a pair of scripts that monitor and report on your internet connectivity. They monitor your internet connection (with user defined packet loss threshold), reconnect after 2 failures, log all up and downtimes, and e-mail the user a monthly status report with downtime recorded and adjusted service fee

Net-snmp: 'net-snmp' provides tools and libraries relating to the Simple Network Management Protocol. The package includes an extensible agent, an SNMP library, tools to request or set information from SNMP agents, tools to generate and handle SNMP traps, and more.

NetCube: NetCube (a.k.a. Jeff's version of The Spinning Cube of Potential Doom) is a python utility for visualizing network traffic in a 3d simulation. The x, y, and z axes correspond to the source IP address, the port number, and the destination IP address, respectively. This applies only to TCP and UDP traffic, of course, but that's the bulk of the traffic out there! Why bother? Well for one, visualization seems to help humans in identifying port scans and the like. See the original The Spinning Cube of Potential Doom page for more info.

NetMess: NetMess is a peer-to-peer file sharing system. Its advantages over other p2p systems include clone detection and the ability to work through an HTTP proxy and through most firewalls (both inbound and outbound). It is decentralized and does not depend on a master server, so it can run in a LAN environment (useful as an information sharing system for small to middle-sized company). It lets its users search and retrieve documents without having to remember their exact location, and can share all file types (audio, video, archives, etc).

NetSPOC: NetSPOC is a Network Security POlicy Compiler. A tool for simplified security management of networks with multiple security domains. NetSPOC takes a description of topology, services and rules and generates access lists for multiple packet filters.

Netboot: 'netboot' boots an operating system through a network interface on an x86 system using common protocols like DHCP and TFTP. It has all the tools necessary to generate bootrom images and boot image files. It can boot DOS (in most variants: MS-DOS, DR-DOS, PTS-DOS, FreeDOS etc.), GNU/Linux, and FreeBSD. It also contains a boot menu compiler. The bootrom code uses the network drivers shipped with each network card, so they can be used with almost any such card available for x86.

Netdude: Netdude (the NETwork DUmp data Displayer and Editor) is a framework for inspection and manipulation of tcpdump tracefiles. It is separated into a GUI-based frontend and a backend library that performs the actual packet manipulation. Both the front- and backend can be extended using plugins, in order to add support for new protocols and to provide modular code to other developers.

Netperfmeter: NetPerfMeter is a network performance meter for the UDP, TCP, MPTCP, SCTP and DCCP transport protocols over IPv4 and IPv6. It simultaneously transmits bidirectional flows to an endpoint and measures the resulting flow bandwidths and QoS. The results are written as vector and scalar files. The vector files can e.g. be used to create plots of the results.

Netprofiler: 'Netprofiler' saves the settings of network devices into files with appropriate names for each device in a folder whose name is specified by the user. These are called netprofiles. Users can then is then easily change the network settings to those saved in the profiles.

Netrik: Netrik is an advanced text mode WWW browser. Its mission is to give you access to as much of the web as possible in text mode, without forsaking any possible comfort. To achieve that, netrik will need many advanced features, including multi-windowing, CSS, Javascript, HTML filtering/rewriting, and maybe some optional graphical capabilities. However, the goal is not to implement as many killer-features as possible; rather, the priorities are a really good user interface, and innovative new features not found in other browsers, making life easier and emphasizing the advantages of text mode. Presently, netrik has all what is necessary for basic web browsing; none of the advanced features are present yet. There are already a few nice little goodies, though.

Netsukuku: Netsukuku is a mesh network or a P2P net system that generates and sustains itself autonomously. It is designed to handle an unlimited number of nodes with minimal CPU and memory resources. Thanks to this feature it can be easily used to build a worldwide distributed, anonymous and anarchical network, separated from the Internet, without the support of any servers, ISPs or authority controls. Keep in mind that it is a _physical network_, it isn't built upon any other existing net, therefore there must be computers linked _physically_ each other, then Netsukuku will build the routes. For more information read the section "2.4 So, WTF is it?" of the document. In order to join to Netsukuku you have to use NetsukukuD, which is the daemon implenting the Npv7 protocol.

NetworkManager: Networking on GNU/Linux should not suck like it does right now for the desktop user. The desktop user should never need to use the command-line to configure their network; it should "Just Work" as automatically as possible and intrude as little as possible into the users workflow. The computer should use the wired network connection when its plugged in, but automatically switch to a wireless connection when the user unplugs it and walks away from the desk. Likewise, when the user plugs the computer back in, the computer should switch back to the wired connection. The user should, most times, not even notice that their connection has has been managed for them; they should simply see uninterrupted network connectivity.

Newrelic-api: Java client library for the New Relic REST APIs built using Jersey and Gson. The library implements over 110 operations across all of the available 35 New Relic services. It is primarily used by applications to automate the configuration of New Relic Monitoring, Alerting and Dashboards, but can also be used for extracting incident and metric data, executing Insights queries, or uploading plugin metrics.

NewsDeliver: NewsDeliver is a simple but customizable NNTP to email gateway written in Python. When invoked (usually by a cron job), it checks for new messages on newsgroups that the user has marked as "watched" and emails a copy of any new messages to the user.

NewsFlash: NewsFlash is a feed aggregator that supports RSS, Atom, and JSON Feed. It complements an account with a web-based feed reader service to synchronize feeds, categories, and article status between devices. Services supported include Miniflux, NewsBlur, Feedbin, FreshRSS and Tiny Tiny RSS. Feed subscriptions are managed using categories and can be imported and exported in OPML format. Content scrapers are used to extract the full text of articles when not available in a feed.

NewsLib: NewsLib is a library of Perl modules for managing Network News services. It's meant to be used for code-reuse and sharing when writing news-based applications. It includes Net::NNTP::Client (simulates a news client), Net::NNTP::Proxy (a proxying news server), and News::NNTPAuth (NNTP authentication).

Newsadmin: 'Newsadmin' is a simple news administration system that features news editing and several separate news editor/ administration accounts. Articles can have a news image that can be uploaded with the article (using news editing form). There is a news archive page for past articles. Long articles can optionally be cut on main view and read using separate readarticle "read more" page.

Newsbeuter: Newsbeuter is an RSS feed reader designed to be used on text terminals on Unix and Unix-like systems. It was developed with texttools users in mind, and thus its interface is similar to tools like mutt and slrn.

Newsd: 'Newsd' is a standalone local NNTP news server for private newsgroup serving on a single server. It is useful for serving private newsgroup(s) to an intranet or the Internet, and can act as a simple mail gateway. However, it does not interface with other news servers and cannot manage distributed news feeds, i.e. Usenet news.

Newspipe: Newspipe is an RSS/Atom aggregator with a difference: It allows you to keep track of your feeds through e-mail - you create an OPML file listing your feeds and Newspipe will collect them, convert them to e-mail messages and send them to your mailbox. This means you can read, organize and archive news feeds using your current mail client (or even webmail), without needing to use a separate program. Newspipe can send you news items as plaintext or HTML mail, both as single items or grouped in a digest.

Newspost: Newspost is a full-featured USEnet binary autoposter. It is meant as an all-in-one posting solution. In addition to posting files, it can post text prefixes, and generate and post .SFV files and .PAR volumes. It supports both yencoding and uuencoding.

Newsstar: Newsstar fetches news and posts it to a local news server: INN and sn are supported. The program can make multiple simultaneous connections, not only to one server, but to several, supporting up to 10 "threads". Before fetching each article, it checks that it hasn't already been downloaded by another thread or in a previous session. It can also "pipeline" article requests to make more efficient use of bandwidth.

Newts: Newts is a notesfile program, a news-like program for use as a message board. Newts is designed for *NIX-like systems, and resembles the Notesfiles program written early in the 1980s at the University at Urbana-Champaign. The client program included emulates the look and feel of Notesfiles, and the UIUC backend is compatible with Notesfiles data files. Future versions of Newts will include a separate daemon to manage multiple local and network connections, additional backends, and additional clients.

Nextcloud: Nextcloud is a free, decentralized and open cloud platform. It allows you to sync your files, calendars and contacts while staying in control of your data. As a platform you can extend it with many existing apps or write your own. With federated sharing, Nextcloud allows you to collaborate with people across different Nextcloud installations. Nextcloud also provides real-time communication through Spreed.me and collaborative editing through LibreOffice Online integration.

Nfswatch: 'nfswatch' monitors the incoming network traffic on an NFS file server, divides it into several categories, and displays on the screen a continuously updated display of the number and percentage of packets received in each category. It can also monitors the NFS reply traffic from a server in order to measure the response time for each RPC.

Nget: 'Nget'is a command line NNTP file grabber. It automatically pieces together multipart postings for easy retrieval, even substituting parts from multiple servers. It handles disconnects gracefully, resuming after the last part successfully downloaded, and caching of header data for quick access.

Ngetdaemon: 'ngetdaemon' lets users quickly and efficiently read and download from Usenet remotely. One click updates and sorts all headers. Posts are grouped together in 'file groups': a post consisting of 100 files is compacted into one line and determined to be complete, incomplete, par fills, etc. There are no buttons, animations, etc. Everything is designed to create as little strain on bandwidth as possible.

Nginx: nginx [engine x] is an HTTP and reverse proxy server, as well as a mail proxy server, written by Igor Sysoev. For a long time, it has been running on many heavily loaded Russian sites including Yandex, Mail.Ru, VKontakte, and Rambler. According to Netcraft nginx served or proxied 15.53% busiest sites in December 2013. Here are some of the success stories: Netflix, Wordpress.com, FastMail.FM. Note that NGINX Plus is proprietary.

Ngrep: 'ngrep' provides most of GNU grep's common features and applies them to the network layer. It is a pcap-aware tool that lets you specify extended regular or hexadecimal expressions to match against data payloads of packets. It currently recognizes TCP, UDP, ICMP, IGMP, and Raw protocols across Ethernet, PPP, SLIP, FDDI, Token Ring, 802.11 and null interfaces, and understands bpf filter logic in the same fashion as more common packet sniffing tools, such as tcpdump and snoop.

Ninpaths: This is an efficient and space-saving inpaths reporting program. It works as follows: you feed it the Path lines via an INN channel feed, and from time to time the program writes all its internal counters accumulated so far to a dump file. Another instance of the program picks up all the dump files, adds them up and formats them into the report.

Nntp2rss: 'nntp2rss' provides a bridge to access newsgroups using an RSS reader. It assembles the latest few articles' subjects of one newsgroup into one feed. Users can read any newsgroup with the same script as the group name is passed as a parameter. The feed can contain up to 25 articles (also a parameter), and there is the option to use Google Groups links to view groups and article texts. Feeds are compliant to RSS 0.91, 1.0, or 2.0, PIE/NECHO 0.1, or Unix mbox.

NoSpam: This is a candidate for deletion: broken links, can't find software elsewhere, not on archive.org, my email to author was returned to sender. Danm (talk) 15:38, 3 December 2017 (EST) NoSpam is a content-based spam filter. It filters incoming mail, sorting spam into a different mail folder. Optionally, it can send a message to the originator of alleged spam informing them that their message was discarded (to make sure legitimate mail can be resent if it contains too many spam-like phrases).

Node.js: Node.js is a JavaScript runtime built on Chrome's V8 JavaScript engine. Node.js uses an event-driven, non-blocking I/O model that makes it lightweight and efficient. Node.js' package ecosystem, npm, is the largest ecosystem of libraries in the world.

Noffle: Noffle is a news (nntp) server optimized for few users and low speed dial-up connections to the Internet. It adds offline reading capabilities to existing news readers. Features include optional auto group subscribe/unsubscribe; full, overview and thread subscription modes; local groups; article expiry time customizable for each group; article request stacking for faster download. Noffle is aimed at the home or smaller organisation that wants to read up to a few hundred newsgroups. It is not suitable for running a complete newsfeed and cannot participate in a properly configured newsfeed.

Ntop: 'ntop' is a network probe that shows network usage in a way similar to what top does for processes. In interactive mode, it displays the network status on the user's terminal. In Web mode, it acts as a Web server, creating an HTML dump of the network status. It sports a NetFlow/sFlow emitter/collector, and an HTTP-based client interface for creating ntop-centric monitoring applications.

ODOP:Spring: More than a spring calculator, ODOP:Spring is full-featured spring design software for engineering custom helical coil springs, including compression, torsion and extension springs. While certainly capable of analyzing the performance of an existing spring design, our open-source and free to use web app is at its best when used to develop solutions to difficult and highly constrained original design problems. Typical spring calculators perform design analysis, requiring users to make repeated inputs (independent variables of the design equations like wire diameter, coil diameter, number of coils and loads) until the desired outputs (dependent variables like deflections, stresses, weight, and estimated cycle life) are achieved. On the other hand, ODOP:Spring performs design synthesis to invert the dependent / independent relationships of the design equations and perform constrained optimization. You input specific goals, and ODOP:Spring returns the variable values that best meet those goals.

OSSEC: From about page: OSSEC has a powerful correlation and analysis engine, integrating log analysis, file integrity monitoring, Windows registry monitoring, centralized policy enforcement, rootkit detection, real-time alerting and active response.

ObscuraCam: https://f-droid.org/en/packages/org.witness.sscphase1/ Obscuracam is a photo and video app for Android that keeps certain information private. Ever capture someone in a photo or video, then realize they may not want to be in it? Not comfortable posting a friend, family member or child’s face on the internet? Worried about the geolocation data in the picture giving away private hideaway? Tired of Facebook, Google and other sites “auto detecting” faces in your photos? Then this is for you, giving you the power to better protect the identity of those captures in your photos, before you post them online. Take a picture or load a photo or video from the Gallery, and ObscuraCam will automatically detect faces that you can pixelate, redact (blackout) or protect with funny nose and glasses. You can also invert pixelate, so that only the person you select is visible, and no one in the background can be recognized. This app will also remove all identifying data stored in photos including GPS location data and phone make & model. You can save the protected photo back to the Gallery or any other “Share” enabled app.

Octod: Octod is a "download manager daemon", i.e. a daemon that listens at the network interface for incoming download jobs and performs them (simultaneously) in the background. It is intended to run on desktop systems as a reliable and fast download manager without the overhead of a graphical user interface, but it can also be used as a centralized download station running in network environments with multiple users. To control the daemon, an easy and self-explanatory network protocol has been defined, so cross-platform, cross-language graphical clients (based on ncurses, Qt, Gtk, or even HTML/PHP) can be implemented.

Odoo: Odoo (previously OpenERP) is a suite of programs that help companies to grow their business.

It aims to be "The Java Web Answer" for rapid application development for Web applications.

OneModel: Today: You can take notes with it. Rearrange them easily, up and down in a list, or up/down in the hierarchy. Link them to each other. Navigate across links with simple keypresses. Make deeply nested lists. Link lists to lists. Compose long paragraphs and attach them. Or do more complicated things if desired, by creating relationship types and using those. Import txt or export txt or html. It's better than the alternatives for some people, because the navigation takes fewer keystrokes, you don't have to read a manual (it's all on the screen, or so I like to think), you can have the same thing in as many places as you want, it is Free (some alternatives are, others are not), and it has immense future potential for becoming a better-structured, much more powerful and flexible wikipedia-like tool, if we work together. Vision: The idea is to have the most efficient personal knowledge organizer (now available in a usable text-based interface), then support mobile access, easy internal automation, and effective sharing and collaboration. Then, to combine efforts and learn as we go until we integrate humankind's knowledge over time. The key differentiators are that it is to be Free, and based on an object model (easily created on the fly as a side-effect of using the system), rather than on massive amounts of words. The knowledge is the same, even if the words can change. One can think of that as "using building blocks of knowledge, starting at an atomic level (i.e. numbers, relationships...), free and efficient." Or, taking the best experiences of online organizer tools and wikis, but more structured, efficient, Free, open, and collaborative; and allowing full individual or organizational control.

OnionShare: What is OnionShare? OnionShare lets you securely and anonymously share files of any size. It works by starting a web server, making it accessible as a Tor onion service, and generating an unguessable URL to access and download the files. It doesn't require setting up a server on the internet somewhere or using a third party filesharing service. You host the file on your own computer and use a Tor onion service to make it temporarily accessible over the internet. The other user just needs to use Tor Browser to download the file from you. How to Use Open OnionShare, drag and drop files and folders you wish to share into it, and click Start Sharing. After a moment, it will show you a .onion URL. This is the secret URL that can be used to download the file you're sharing. Send this URL to the person you're sending the files to. If the files you're sending aren't secret, you can use normal means of sending the URL, like by emailing it, or sending it in a Facebook or Twitter private message. If you're sending secret files then it's important to send this URL securely. The person who is receiving the files doesn't need OnionShare. All they need is to open the URL you send them in Tor Browser to be able to download the file.\

Online-bookmarks: 'online-bookmarks' is a bookmarks management system that stores bookmarks, favorites, and links on the Web where they actually belong.

OpenResty aims to run your server-side web app completely in the Nginx server, leveraging Nginx's event model to do non-blocking I/O not only with the HTTP clients, but also with remote backends like MySQL, PostgreSQL, Memcached, and Redis. OpenResty is not an Nginx fork. It is just a software bundle. Most of the patches applied to the Nginx core in OpenResty have already been submitted to the official Nginx team and most of the patches submitted have also been accepted. We are trying hard not to fork Nginx and always to use the latest best Nginx core from the official Nginx team.

OpenSCAP: From their repo: The oscap program is a command line tool that allows users to load, scan, validate, edit, and export SCAP documents. OpenSCAP uses SCAP which is a line of specifications maintained by the NIST. SCAP was created to provide a standardized approach for maintaining system security. New specifications are governed by NIST’s SCAP Release cycle in order to provide a consistent and repeatable revision workflow. OpenSCAP mainly processes the XCCDF which is a standard way of expressing a checklist content and defines security checklists. It also combines with other specifications such as CPE, CCE and OVAL to create a SCAP-expressed checklist that can be processed by SCAP-validated products. For more information about the SCAP please refer to SCAP Standards.

OpenStego: Steganography is the science of hiding secret message inside another larger and harmless looking message. This is one notch above regular cryptography; which just obscures the original message. Steganography tries to conceal the fact that there is a message in the first place. Steganographic message often appears to be something else than the original (secret) message, like a picture, sound, larger text, etc. OpenStego is the free Steganography solution. It is a tool implemented in Java for generic steganography, with support for password-based encryption of data. It supports plugins for various steganographic algorithms.

Pagekite: PageKite is a system for connecting your localhost servers to the public Internet, giving them names and making them globally accessible. It works on most common operating systems and it doesn't matter what kind of Internet connection you have. The PageKite back-end configures DNS for your server and establishes communication with our global pool of front-end relays. These relays have public IP addresses and are visible on the global Internet, which makes it possible for them to accept incoming requests on your server's behalf. These requests get forwarded (proxied) over the tunnel to your server, and any replies travel back the same way.

Pagure: With pagure you can host your project with its documentation, let your users report issues or request enhancements using the ticketing system and build your community of contributors by allowing them to fork your projects and contribute to it via the now-popular pull-request mechanism.

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.

Phptelemeter: phptelemeter is a script that can read the Web pages for the Web-based "quota" monitor made available by ISPs. These pages can contain both the actual status and the status since the last "reset", which happens on a date set by the ISP. This is what makes up the used quota. It supports Telenet, Dommel, Skynet, and Scarlet for Belgium and UPC for the Czech Republic.

Pidgin-otr: "Off-the-Record Messaging plugin" (or pidgin-otr) is a Pidgin plugin for secure messaging using a protocol known as OTR. Like similar protocols, OTR allows you to hold secure (encrypted and authenticated) conversations. In addition, messages themselves are not signed (that is, they are off-the-record) and remain secure even if your private key is compromised (previous communication streams cannot be decrypted). These features are useful, for example, for journalists. Note, though, that these are technical restrictions not legal ones (a court may consider other evidence). This plugin offers various methods of initial authentication (challenge/response, shared secret), autogenerates keys, and retains keys so that you can continue conversations with people you have previously authenticated. It does not interfere with unencrypted conversations, although you can prompt the other user to install pidgin-otr (or another OTR client) themselves.

Pmacct: 'pmacct' gathers IP traffic information (bytes counter and number of packets). Aggregation of statistics is done using simple primitives (MAC addresses, IP addresses, ports, and IP protocol) that can be used alone or combined together to form complex aggregation methods. Counters are either global or historical (aggregated and separated at fixed timeslots). Data is stored in an in-memory table or using an SQL database (MySQL or PostgreSQL); recovery actions are available to avoid data loss during DB failures. Gathering packets off the wire is done using the pcap library; promiscuous mode is only set during online operations.

Polipo: 'Polipo' is a lightweight caching Web proxy that was designed as a personal cache. It is able to cache incomplete objects and will complete them using range requests. It will use HTTP/1.1 pipelining if supported by the remote server.

Pound: Pound is a reverse HTTP proxy, load balancer, and SSL wrapper. It proxies client HTTPS requests to HTTP backend servers, distributes the requests among several servers while keeping sessions, supports HTTP/1.1 requests even if the backend server(s) are HTTP/1.0, and sanitizes requests. Pound proxies HTTO _and HTTPS requests simultaneously. In addition, it knows about failed back-end servers and can redirect requests according to their availability. It can run as setuid/setgid and/or in a chroot jail. Pound does not access the hard-disk at all (except for reading the certificate file on start, if required, and the pid file) and should thus pose no security threat to any machine. It needs at least the configuration file (read-only) and, optionally, the HTTPS server certificate (read-only).

Ppp: The PPP Daemon lets *nix machines connect to the internet through dialup lines, using the PPP protocol, as a PPP server or client. It works with 'chat', 'dip', and 'diald', among (many) others, and Supports IP, TCP, UDP and (for Linux) IPX (Novell).

Ppplog: 'ppplog' tracks online PPP sessions. Once started, it detects when you are online and automatically calculates costs according to your local phone company, regardless of whether the company calculates by units (fix price for a unit, units differ in length) or by seconds (unitlength = n sec, price differs). The setup for your phone company is stored in a config file which can be easily changed.

Privacy Badger: Privacy Badger automatically blocks spying ads and invisible trackers as you browse. It's there to ensure that companies can't track your browsing without your consent. Privacy Badger sends the Do Not Track header with each request and evaluates the likelihood that you are still being tracked. If a domain appears to be tracking you on multiple websites, Privacy Badger automatically blocks your request from being sent to the tracking domain. Our extension shows you one of three states for each tracker. Red means block the tracker. Yellow means that we don't send cookies or referers to the tracker. Green means unblocked (probably because the third party does not appear to be tracking you - yet). You can click on the Privacy Badger icon in your browser's toolbar if you wish to override the automatic blocking settings. Nothing can stop the Privacy Badger from eating cookies when it's hungry! Privacy Badger is a project of the Electronic Frontier Foundation (https://www.eff.org)

ProZilla: ProZilla is a multi-threaded download accelerator for Linux which supports both HTTP and FTP protocols. It makes multiple connections to the server and downloads the file in portions, thus giving a much better speed rate than the conventional download programs which use a single connection. Resuming connections is fully supported and customizable. The new FTPSearch feature enables retrieving of mirrors, and also pings them to select the fastest server available. Both the number of mirrors to retrieve and the number of servers to ping at once are fully customizable.

Procwatch: Procwatch watches a /proc filesystem for new processes. When a process is created, procwatch reports the time, the username, the PID, and the binary that was run. Its output is suitable for logging to log files and is geared for system administrators who are testing a new but as yet untrusted UNIX system. Although it cannot detect, and is not proof against, hacked loadable kernel modules that have modified /proc, it is useful in watching for possible rogue binaries.

Program Guard: Program Guard allows the user of a GNU/Linux workstation to specify which applications are allowed to make TCP/IP connections to the Internet. Application program names can be specified by listing them in a file (Static Mode) or by querying the user (Query Mode). In Query Mode, connection attempts by unknown programs result in a Program Guard dialog box being displayed. In addition to providing connection information, this gives the workstation user the option of allowing or blocking the program either for the current instance of the program or for all future instances. It consists of a daemon, a kernel module, and a GUI interface component and makes use of the GNU/Linux Netfilter interface.

Prousdata: Prousdata restores files and folders for next user session. Main tool helps to manage protections scope: user, elements, forbids.

Proxyknife: GNU Proxyknife is a customizable multithread proxy hunter. It can help users behind strict firewall find suitable free proxies. gnu Proxyknife reads proxylist1 from the file, stdin or the web, then validates the free proxies and prints the good ones. Time intervals and the others which are userful to estimate the speed or capability of every proxy are also printed. The whole processing can be customized by the user, which is different from the other hunters. In url mode, Proxyknife can read a large number of proxies on machines with little memory. It works on GNU/Linux, SunOS, OSF1 and more.

Pseudo-cron: 'pseudo-cron' lets users run cron jobs on a Website without shell access (ISPs usually charge users additional money for shell access). When a user requests a page which uses pseudo-cron, it checks if any cron jobs should have been run since the previous request. If there are, they are run and logged. Its syntax is much like cron's and can run any include()able PHP file.

Red Matrix: Originally authored by Mike Macgirvin (also the original author of Friendica), the RedMatrix is a super network created from a huge number of smaller independent and autonomous websites - which are linked together into a cooperative publishing and social platform. It consists of an open source webapp providing a complete multi-user decentralised publishing, sharing, and communications system - known as a "hub". Each hub provides communications (private messaging, chat, blogging, forums, and social networking), along with media management (photos, events, files, web pages, shareable apps) for its members; all in a feature-rich platform. These hubs automatically reach out and connect with each other and the rest of the matrix. Privacy and content ownership always remain under the direct personal control of the individual; and permission to access any item can be granted or denied to anybody in the entire matrix. What makes the RedMatrix unique is what we call "magic authentication" - which is based on our groundbreaking work in decentralised identity services. No other platform provides this ability. Within the matrix the boundaries between different hubs are blurred or seemingly non-existent. Identity in the matrix is considered transient and potentially nomadic. "Who you are" has nothing to do with "what computer you're connected to", and website content can adapt itself according to who is viewing it. You have the ability to "clone" your identity to other hubs; which allows you to continue to communicate with your friends seamlessly if your primary hub is ever disabled (temporarily or permanently). The RedMatrix is ideal for communities of any size, from private individuals and families to online forums, business websites, and organisations. It can be used by anybody who has communications or web content that they wish to share, but where they desire complete control of whom they share it with.

Resgen: A Ruby-based application to automate the lengthy steps for writing and dating cover letters. Generate PDFs from Libre Office .odt templates on the fly and save a copy of the job posting, all without ever having to leave your terminal! The only thing Resgen doesn't do for you is actually send the resume (but with some minor tweaks, it could do that, too!) Zero technical skill required for use How it works: - Initialize Resgen by navigating to it's directory in your terminal and running ruby resgen - Resgen will prompt you for information about your job prospect & even alert you if you've applied there before - Based on the information you give Resgen, a customized cover letter with the employer name and current date will be generated and merged with your regular resume, straight from .odt templates; no needing to have to create the PDFs by hand any time you want to update it - Resgen does it for you - Resgen also scrapes the job posting and saves a textual copy (and dates the file), so you have a point of reference when you're called in for an interview Note: This was built & tested in a GNU/Linux desktop environment; it should also work for Mac or Windows, so as long as you have a Ruby environment with Shell command capability.

Rest suite: Server-side Javascript library that wraps parts of the Netsuite SuiteScript API (v2010.1). This interface should be more performant than the SOAP based interface as it allows 50 simultaneous connections per set of login credentials. Note that NetSuite's point system is seemingly arbitrary and we've tried to provide better error handling wherever possible. Designed as a replacement for netsuite-rest-client

Retawq: 'retawq' is an interactive, multi-threaded network client (web browser) for text terminals on computers with *nix-like operating systems. It is fast, small, nicely configurable, and comfortable; e.g. the low-level network communications are performed in a non-blocking way, and you can keep open as many "virtual windows" as you want and work simultaneously in two of them in a split-screen mode.

Also includes support for braille and screen readers.

Riak: High Performance Storage

Ricochet: Ricochet uses the Tor network to reach your contacts without relying on messaging servers. It creates a hidden service, which is used to rendezvous with your contacts without revealing your location or IP address. Instead of a username, you get a unique address that looks like ricochet:rs7ce36jsj24ogfw. Other Ricochet users can use this address to send a contact request - asking to be added to your contacts list. You can see when your contacts are online, and send them messages (and soon, files!). Your list of contacts is only known to your computer - never exposed to servers or network traffic monitoring. Everything is encrypted end-to-end, so only the intended recipient can decrypt it, and anonymized, so nobody knows where it’s going and where it came from.

Riot-web: Communicate the way you want with Riot - a universal secure chat app entirely under your control. Riot is for everyone, from casual chat to high powered collaboration and is built on the Matrix protocol, a standard for open, decentralised communication.

It downloads headlines from a configurable list of regularly-updated Web sites, and merges the items into a single list of all the latest news. It can be used to keep track of several favourite sites, or as an automatic supply of filler material on a public Web site. It uses local files to store its persistent information, so you don't need a database or non-default PHP library support.

Rnetclient: Substitute the non-free software for sending income tax declaration suggested by Brazilian Government.

Rocks: Rocks (Reliable Sockets) protects sockets-based applications from network failures, especially those common to mobile computing (link failures, IP address changes, and extended periods of disconnection). Rock-enabled programs keep running after these events; their broken connections recover automatically (even when one end of the connection has a new IP address), without loss of in-flight data, when connectivity returns. The program also authenticates the resumed connections. It works entirely at user level and is transparent to ordinary applications.

Rockstor: RockStor is a free software Network Attached Storage solution developed on top of GNU/Linux and BTRFS filesystem. It comes with a easy to use web-ui and supports all popular file sharing protocols including NFS, Samba/CIFS and SFTP.

It serves files, includes an mmap(2) file cache and supports directory listings, CGI script execution (NPH scripts only), virtual hosts, aliases, and shared object scripts: (fast CGI scripts that are dynamically linked into the server memory at runtime.

SFT: This is a candidate for deletion: Links broken. From maintainer "Indeed, I think it is time to retire SFT from the FSF directory, it is unmaintained and probably obsolete". Poppy-one (talk) 11:40, 30 July 2018 (EDT) . SFT (Simple File Transfer) is a file transfer program, a bit like rcp. It is designed to simplify file transfers from one computer to an another when they are connected to the Internet. The person receiving the file has to run the program in server mode (-s), while the sender of the file has to run the program in client mode (-c), specifying the destination host IP and the file names. File integrity is checked by using checksums. Server options include -k (keeps the server running after sessions), -d (+ path- lets you choose the reception directory), and -l (+ number- limits the number of incoming bytes). For the client, -d + path lets you choose the program's working directory.

SIP Express Router

* " November 04, 2008 - SER joins the sip-router project "

SER or SIP Express Router is a very fast and flexible SIP (RFC3621) server. It handles thousands of calls per second on low-budget hadware. A C shell-like scripting language provides full control over the server's behaviour. Its modular architecture lets users load only the required functionality. The following modules are available: digest authentication, CPL scripts, instant messaging, MySQL support, a presence agent, Radius authentication, record routing, an SMS gateway, a Jabber gateway, a transaction module, a registrar, and user location.

SNMPTT: SNMPTT is an SNMP trap handler for use with the NET-SNMP/UCD-SNMP snmptrapd program. It translates received traps into friendly messages using variable substitution. Output is to STDOUT, text log file, syslog, NT Event Log, MySQL, PostgreSQL, or an ODBC database. The software can also execute user defined programs.

SNORT: Snort is a network intrusion detection system that performs real-time traffic analysis and packet logging on IP networks. It can perform protocol analysis, content searching/matching and can be used to detect a variety of attacks and probes, such as buffer overflows, stealth port scans, CGI attacks, SMB probes, OS fingerprinting attempts, and more. Snort has three primary uses: as a straight packet sniffer like tcpdump(1), as a packet logger (useful for network traffic debugging, etc), or as a full blown network intrusion detection system. Snort logs packets in either tcpdump(1) binary format or in Snort's decoded ASCII format to logging directories that are named based on the IP address of the "foreign" host. It should work any place libpcap does. Snort uses a flexible rules language to describe traffic that it should collect or pass, as well as a detection engine that utilizes a modular plugin architecture. It also has real-time alerting capabilities.

SSHMan

SSHMan is a simple ssh agent helper, along the lines of keychain. Some of sshman's features:

Persistant management of ssh agents.

Samhain: Samhain is a file system integrity checker that can be used for both single hosts and networks. You can trace what changes have occurred in your system, when they occurred, and who was logged in at the time. The program uses cryptographic checksums to monitor file integrity and detect unauthorized modifications of a file system. It's designed for tamper resistance, even if an intruder has obtained root privileges. In addition to forwarding reports to the log server via authenticated TCP/IP connections, several other logging facilities (e-mail, console, tamper-resistant log file, and syslog) are available.

Sandstorm: Some web applications, particularly federated ones, are suitable for running on your local machine rather than hosting on an remote server you don't control. Sandstorm is a platform designed to help you run and maintain these applications, retain your data on your own machine, and optionally use their federation features to contact and publish to remote servers at your own discretion. Representative webapps supported include Ghost (blogging), GNU MediaGoblin (media sharing), Mailpile (email), Tiny Tiny RSS (feedreading) and others.

SecureServ: SecureServ is an IRC trojan detector. It's much like a virus scanner, but aimed at IRC networks. Using several methods, including version checks, behavior analysis, and general pattern matching, it aims to detect trojans, viruses, and floodbots which connect to your IRC network. Its "brains" are based on a "Definition file" which contains information on how to detect trojans. To update detection for new trojans, you only have to download a new file.

Seespee: Modified from README.md: Generate or validate a Content-Security-Policy header for a website. The website is crawled for scripts, stylesheets, images, fonts, application manifests etc., which will be listed by their origin. Inline scripts and stylesheets will be hashed so 'unsafe-inline' can be avoided.

Semantic MediaWiki: Semantic MediaWiki lets you store and query data within the wiki's pages and is also a full-fledged framework, in conjunction with many spinoff extensions, that can turn a wiki into a powerful and flexible “collaborative database”. All data created within SMW can easily be published via the Semantic Web, allowing other systems to use this data seamlessly. This very website, the Free Software Directory is powered by Semantic MediaWiki.

Send (file sharing): Send is a self-hosted tool that allows sending files with encryption. It's a community fork of Firefox Send, a discontinued service by Mozilla. Files are encrypted in the browser before being uploaded to the server. Files are stored for 24 hours then deleted from the server. ffsend is a CLI client for Send. A list of available instances can be found here.

SendIP: 'SendIP' sends arbitrary IP packets. It has a large number of options to specify the content of every header of a RIP, RIPng, BGP, TCP, UDP, ICMP, NTP, or raw IPv4/IPv6 packet. It also allows any data to be added to the packet. Checksums can be calculated automatically, but if you wish to send out wrong checksums, that is supported too.

Ser2net: ser2net provides a way for a user to connect from a network connection to a serial port. It provides all the serial port setup, a configuration file to configure the ports, a control login for modifying port parameters, monitoring ports, and controlling ports. supports RFC 2217 (remote control of serial port parameters), but you must have a complient client

Sercd: 'sercd' is an RFC 2217-compliant serial port redirector. It lets you share a serial port through a network. It is based on sredird.

Serlvers: Serlvers is a set of Erlang modules designed to help in the implementation of IP services (i.e. TCP/IP or Internet servers). Serlvers consists of a set of behaviours to abstract the internals of each protocol, and other modules to help with the infrastructure. The goal is that when making a server, you only need worry about how to store, handle, process, etc. the information instead of the internals of each protocol (to save countless hours of RFC reading). This package is outdated and no longer maintained.

Sesele: SeSeLe is a command-line wizard to create and manage X.509 certificates in two ways: Self-signed certificates + Certification Authority, and Let's Encrypt certificates. Letsencrypt management is intended to call ACME-client for certificates renewal and files redistribution to unprivileged hosts (those that can't attend TCP/443 port). Generated certificates are useful for most TLS secured services such as HTTPs, IMAPs, POP3s, SMTPs, etc. For self-signed files, the only thing you will need to remember are passphrases.

Shareaza: Shareaza is a multi-network peer-to-peer ( P2P ) file-sharing client supporting many different torrent protocols.

Sharesecret: Sharesecret splits a secret into some parts, given a threshold. It can recalculate the secret by joining threshold parts. If somebody knows only threshold - 1 parts, he knows only the length of the secret.

Sharktorrent: Sharktorrent is a cross-platform BitTorrent client. It is written in C++ using Qt4 and Arvid Norberg's libtorrent.

Shishi: Shishi is a free implementation of the Kerberos 5 network security system. It is used to allow non-secure network nodes to communicate in a secure manner through client-server mutual authentication via tickets. It includes a library ('libshishi') that developers can use to add support for RFC 1510, and a command line utility ('shishi') that lets users interface with the library, acquire and manage tickets, and more. Included are also a TELNET client and server (based on GNU InetUtils) for remote network login, and a PAM module for host security. Shishi is still alpha quality. Basic support for acquiring and managing tickets are working. The KDC server side can only serve initial authentication requests. DES, 3DES and AES cipher suites are supported.

Siege: Siege is a free software regression test and benchmark utility that lets Web designers measure the performance of their code under a heavy load of hits. 'Siege' lets the user hit a server with an adjustable number of concurrent users, thus placing the server "under siege." It can stress test a single URL with a user defined number of simulated users, or it can read many URLs into memory and stress them simultaneously. The program reports the total number of hits recorded, bytes transferred, response time, concurrency, and return status. Most features are configurable with command line options, which also include default values to minimize the complexity of the programs's invocation.

Silk Tree: This is a candidate for deletion: 1. No files sources found cannot download. Silktree synchronizes /etc/passwd and /etc/group files from the head node to a list of child nodes via SSH. At the lowest level, six Debian system utilities are employed: {add,del}{user,group}, {user,group}mod. The transaction is done as a non-root user on both the head node and the child nodes. Several read-only sudo-capable mini-scripts on the child nodes ensure limitations and commit the changes to /etc. The end-to-end check ensures a reliable update.

SilverTunnel-NG: SilverTunnel-NG is a Java library that implements and encapsulates all the complex network protocol stuff needed for anonymous communication over the Tor anonymity network. SilverTunnel-NG Netlib can be easily integrated in almost every existing and new Java application. The library requires Java 1.6/Java SE 6 or a newer version.

• Runs Multi-Thread lisp programs on Single-Thread SBCL implementations.

SimpleLogin: SimpleLogin is a service that allows users to use email aliases through its web application. Users can prevent online services from knowing their real email address by using email aliases when signing up. If an alias is no longer needed, it can simply be deleted.

Simplex: Simplex is an encrypted, decentralized messaging service for instant messaging, voice, and video calls. Unlike other messaging platforms, SimpleX has no identifiers assigned to the users. It does not rely on phone numbers, domain-based addresses (like email or XMPP), usernames, public keys or even random numbers to identify its users. To deliver messages SimpleX uses pairwise anonymous addresses of unidirectional message queues, separate for received and sent messages, usually via different servers. Using SimpleX is like having a different “burner” email or phone for each contact, and no hassle to manage them. This design protects the privacy of whom you are communicating with, hiding it from SimpleX platform servers and from any observers.

Sinx: Sinx is a management software designed for non-profit associations of modest size. The program runs in a LAMP server Ideally could be the same in which the association purchased its domain space for your website. Sinx has the typical characteristics of a registry to keep the management, accounting, and create pre-printed forms, has a login system with two levels of users, but tries to respond to the expressed needs of a group to work with ease

Sipcalc: 'Sipcalc' is an advanced console-based IP subnet calculator. It can take multiple forms of input (IPv4/IPv6/interface/hostname) and output a multitude of information about a given subnet.

Slcl: slcl is a simple and lightweight implementation of a web file server, commonly known as "cloud storage" or simply "cloud", written in C99 plus POSIX.1-2008 extensions. It requires no client-side JavaScript and can run on inexpensive servers with minimal resource footprint.

Slrn: 'slrn' (s-lang read news) is a newsreader that runs in console mode on various *nix systems. In addition to having the usual features of a newsreader, slrn supports scoring rules to highlight, sort or kill articles based on information from their header. It allows free key-bindings and can easily be extended using the sophisticated s-lang macro language. Users can read offline by using either slrnpull (included) or a local newsserver.

Sltd: sltd daemonizes multiple slt instances to accept TLS/SSL connections on multiple ports, each one to forward traffic to different backend hosts depending on the intended destination. sltd works as a multiprotocol reverse proxy without adding nor rewriting service data (such as X-Forwarded-For header).

Smart HTTPS: Automatically changes HTTP addresses to the secure HTTPS, and if loading encounters error, reverts it back to HTTP.

SmartCache: Smart Cache is a pure Java proxy cache server. It can cache any pages and make them available for offline browsing. Other features include a URL filter, cookie filter, ability to fake User-Agents, Referer, and Cookie headers, Web forwarder (accelerator) mode, background downloading, multiple logs, fast operation, very configurable garbage collection, cache directory structure copies server structure, and cached files that are ready for use (no headers inside). It can be also used as a replacement for your browser's internal diskcache, which makes faster, more anonymous and offline browsing available.

Snortalog: Snortalog summarizes Snort logs, making it easy to view any network attacks detected by Snort. It can generate charts in HTML and text output. It works with all versions of Snort and all preprocessors (spp_stream4, spp_portscan, spp_decoder, etc.), and can analyze logs in three formats: syslog, fast, and full snort alerts. It can also specify the number of occurences to view, and can resolve IP addresses and domains.

Snowbox: 'Snowbox' is a small (600 lines of code) and secure POP3 server written in Perl. It runs exclusive from 'inetd' and is easy to set up. It implements all necessary POP3 commands, supports APOP authentication, and drops root privileges and continues running as a user process after the authorization stage. The maildrop is kept in memory while running; no temporary files are written.

Snowdrift: Snowdrift is a web-based platform for hosting sustainable crowdfunding for projects. The contribution process involves patrons pledging to match other patrons to create a network of support for projects. The software is being developed to serve the needs of the eponymous website (Snowdrift.coop) (which funds only free/libre projects (including free software)). Currently, the platform is not intentionally designed for running other websites, although anyone is free to do so. Long-term plans include separating the accessory functions so they may be used independently. Besides the fund-raising functions, the platform includes accessory tools such as wiki pages, discussion, and ticketing.

Snownews: Snownews is a text mode RSS/RDF newsreader. It supports RSS feeds that comply to W3C's RDF 1.0 specification and Radio Userland's 0.9x and 2.0. Snownews depends on ncurses and uses libxml2 for XML parsing.

Socat: Socat is a relay for bidirectional data transfer between two independent data channels. Data channels may be files, pipes, devices (terminal or modem, etc.), or sockets (Unix, IP4, IP6 - raw, UDP, TCP), etc. It provides forking, logging, and tracing, different modes for interprocess communication, and many more options. It can be used, for example, as a TCP relay (one-shot or daemon), as an external socksifier, as a shell interface to Unix sockets, as an IP6 relay, as a netcat and rinetd replacement, for redirecting TCP-oriented programs like brutus to a serial line, or to establish a relatively secure environment (su and chroot) for running client or server shell scripts with network connections.

Social: GNU social gives you a powerful social network that is federated. GNU social is a social networking platform. It helps people in a community, company or group to exchange short status updates, do polls, announce events, or other social activities (and you can add more!). Users can choose which people to "follow" and receive only their friends' or colleagues' status messages. It provides a similar service to proprietary social network sites, but is much more awesome. With a little work, status messages can be sent to mobile phones, instant messenger programs (using XMPP), and specially-designed desktop clients that support the Twitter API. GNU social supports an open standard called OStatus that lets users in different networks follow each other. It enables a distributed social network spread all across the Web.

Socketpipe: 'Socketpipe' directly connects the input/output of a remote process with local programs over a TCP/IP socket. Although the initial communication setup is performed through client-server intermediaries such as SSH or RSH, the communication channel that socketpipe establishes is a direct socket connection between the local and the remote processes, similar to a local pipe. The use of socketpipe removes the inefficiency of multiple data copies and context switches through RSH/SSH, and can in many cases offer dramatic throughput improvements.

SocksiPy: This module was designed to allow developers of Python software that uses the Internet or another TCP/IP-based network to add support for connection through a SOCKS proxy server with as much ease as possible.

Sonar Sedcat Plugin: Sedcat is a plugin that provides metrics about quality of unit testing of a software project. These metrics are the quality of unit tests as a percentage and recommended actions to improve that quality in order of priority. These metrics are calculated from expert systems created with the tool xfuzzy at software project level.

Spam Assassin: SpamAssassin is a mail filter that uses heuristic tests on mail headers and body text to identify spam. Mail can then be optionally tagged as spam for later filtering using the user's own mail user-agent application. The program has a command line tool to perform filtering, as well as Mail::SpamAssassin, a set of Perl modules which implement a Mail::Audit plugin; this lets SpamAssassin be used in a Mail::Audit filter or in a spam-protection proxy POP/IMAP server.

Spaminator: Spaminator is a combination of a MySQL and Perl backend script and a PHP frontend that results in an easy-to-use Web interface for managing Sendmail's built-in anti-spam functionality.

Spinner: Spinner keeps telnet and ssh links from dropping due to inactivity. Many firewalls and some ISPs drop connections when they are perceived as idle. Spinner acts as a keep-alive by constantly sending a tiny amount of data over the link, preserving the connection. It displays a little "spinning" ASCII character in the top left corner of your terminal. It can also be activated with the -n switch so that, instead of displaying a spinner, it simply sends out a periodic null character to the terminal. It supports any terminal capable of handling VT100-style escape codes. It also has a mode called "Ghost in the Machine" mode, which you can use to write the spinner character to ANY tty, not just your own.

Splonk: Splonk is a Spam eliminator that works by first accepting certains items that you always want (such as mailing list messages), then rejecting certain people you never want mail from. After that, it looks for common spam patterns. Not all spam may be rejected by this section but it does keep the noise down. Any mail that gets through all this is tested to see if it is actually for you, either by direct addressing or by coming from someone you know who hides the recipient list.

Spyce: SPYCE is a Web server plugin that supports simple and efficient Python-based dynamic HTML scripting. Those who like Python and are familiar with JSP, PHP, or ASP, should look at this engine. It can generate dynamic HTML content just as easily, using Python for the dynamic parts. Its modular design makes it very flexible and extensible. It supports FastCGI, CGI and mod_python to plugin into Apache and most other Web servers, and can also be used as a command-line utility for HTML pre-processing, or as a web server proxy.

Sqltutor: Interactive web based tool for learning SQL by examples. GNU Sqltutor consists of two modules: a database of questions and answers and a simple CGI interface for running tests. Questions are chosen at random for each session, submitted queries are checked against correct answers stored in the database. Query results differing only in column permutations are evaluated as correct. For each session queries and answers are logged and the final score is evaluated when the test is finished. GNU Sqltutor is written in C++ with lipqxx library to connect to PostgreSQL database.

The focus of the strongSwan project is on strong authentication mechanisms using X.509 public key certificates and optional secure storage of private keys on smartcards through a standardized PKCS#11 interface. A unique feature is the use of X.509 attribute certificates to implement advanced access control schemes based on group memberships.

SubNetCalc: SubNetCalc is an IPv4/IPv6 subnet address calculator. For given IPv4 or IPv6 address and netmask or prefix length, it calculates network address, broadcast address, maximum number of hosts and host address range. The output is colourized for better readability (e.g. network part, host part). Also, it prints the addresses in binary format for better understandability. Furthermore, it can identify the address type (e.g. multicast, unique local, site local, etc.) and extract additional information from the address (e.g. type, scope, interface ID, etc.). Finally, it can generate IPv6 unique local prefixes.

Subdownloader: SubDownloader is a program for automatic find and download/upload subtitles for your movies/series (MKV,MP4,AVI,etc).

Sugerplum: Sugarplum is an automated spam-poisoner. It feeds large amounts of realistic but useless data to wandering spam-bots such as EmailSiphon, Cherry Picker, etc. This contaminates spammers' databases so much as to require culling out large portions (including any real data) and/or instructing spambots to avoid your site. Sugarplum detects so-called "stealth" spambots, and can activate firewalls or more aggressive countermeasures at the administrator's option. It includes Apache mod_rewrite rules for known spambots.

Surblhost: Surblhost is a small command-line program that looks up hostnames in the Spam URI Realtime Blocklists (SURBL). Hosts that are blacklisted means that global spam email have been reported to contain links to these hosts. Many spam filtering programs use the SURBL to aid in the filtering process, but this program can serve many other needs. In fact, it was written to provide safe URL redirection for an online service.

XML Boiler

I wrote a specification (congratulate me with great work) for automatic transformation of XML documents based on namespaces, written a software (XML Boiler) to implement these transformations. Written a short tutorial for XML Boiler. There was no automatic way to transform between XML files of different formats previously. This new way is a technological revolution. Most of the specification was implemented in Python programming language, resulting in this free software. The most important current project goal (as of Apr 2019) is to rewrite the entire project in D programming language (because Python was found too slow and also not enough reliable). Additional project purpose: Develop some general purpose libraries for D programming language. The benefits of the project include:

freely intermix tag sets of different sets of tag semantics (using XML namespaces), without disturbing each other (such as by name clash) in the global world
add your new tags to HTML (and other XML-based formats)
get rid of using HTML in future Web, switch it to proper semantic XML formats
make XSL-format based browsers with automatic generation of XSL from other XML formats
make automatic coloring of source listings (for example)
add macroses and include (such as by XInclude) other files in XML
intermix different XML formats, with intelligent automatic processing of the mix
embed one XML format in another one
automatically choose the order of different XML converters applied to your mixed XML file
make browsers to show your XML in arbitrary format
make processing XML intelligent (with your custom scripts)
integrating together XML conversion and validation scripts written in multiple programming languages
associating semantics (such as relations with other namespaces and validation rules) to a namespace
semantics can be described as an RDF resource at a namespace URL (or a related URL)
many more opportunities
integrate all of the above in single command

XWiki Enterprise: XWiki Enterprise is a professional wiki with enterprise features such as Blog, strong rights management, LDAP authentication, PDF export, full skining and more.

Xidel: Xidel is a command line tool to query data from HTML/XML web pages, JSON-APIs and local files. It implements interpreters for XPath 2, XPath 3, XQuery 1, XQuery 3, JSONiq, CSS selectors and custom pattern matching. XPath and CSS selectors are the most efficient way to select certain elements from XML/HTML documents. JSONiq (with custom extensions) is an easy way to select data from JSON. XQuery is a Turing-complete superset of XPath and allows arbitrary data transformations and the creation of new documents. Pattern matching is for XML/HTML documents what regular expressions are for plaintext, i.e. pattern matching behaves like a regular expression over the space of tags, instead over the space of characters. Xidel implements a kind of internal pipes to pipe HTTP requests from one query to the next, so there is no need to distinguish selecting links and downloading the data referenced by them. Therefore arbitrary complex queries going over arbitrary many pages can be executed with a single call of Xidel.

Xindice: Xindice is an native XML database intended to manage large numbers of small XML documents. It stores and indexes compressed XML documents; the server queries these collections using XPath. The server is lightweight and can be embedded in custom applications or run as a standalone database. This is the project formarly known as dbxml; the name change became effective December 2001.

Xinetd: xinetd is a replacement for inetd, the internet services daemon. Anybody can use it to start servers that don't require privileged ports because xinetd does not require that the services in its configuration file be listed in /etc/services. It can do access control on all services (multi-threaded or single-threaded, and for both TCP and UDP protocols) based on the address of the remote host and time of access. It supports internal access control, the use of the libwrap library, and IPv6 with access control.

Xnetintf: 'Xnetintf' is an X Windows application that manages network interfaces. The current interface state is depicted through a series of bitmaps, and a mouse click in the window initiates a state transition. Xnetintf uses a per-interface configuration file to supply commands that check and toggle state, as well as a program to run after the state change completes. The package includes a command line interface.

This package provides the software needed to monitor a host using a Zabbix agent.

Zeek: Zeek is a powerful network analysis framework that is much different from the typical IDS you may know. (Zeek is the new name for the long-established Bro system. Note that parts of the system retain the "Bro" name, and it also often appears in the documentation and distributions.) While focusing on network security monitoring, Zeek provides a comprehensive platform for more general network traffic analysis as well. Well grounded in more than 20 years of research, Zeek has successfully bridged the traditional gap between academia and operations since its inception. Today, it is relied upon operationally by both major companies and numerous many educational and scientific institutions for securing their cyberinfrastructure. Zeek was originally developed by Vern Paxson. Robin Sommer now leads the project, jointly with a core team of researchers and developers at the International Computer Science Institute in Berkeley, CA; and the National Center for Supercomputing Applications in Urbana-Champaign, IL.

Zim: Zim brings wiki-like editing to your local desktop. Every WYSIWYG page is saved as a text file with wiki markup. Pages can contain clickable links to other pages, and are saved automatically. Creating a new page is as easy as linking to a non-existing page. This tool is intended to keep notes, drafts and TODO lists, but also includes extensions for advanced features such as HTML publishing and equation editing.

Ziproxy: 'ziproxy' is a forwarding (non-caching) proxy that gzips text and HTML files, and reduces the size of images by converting them to low quality JPEGs. It is intended to increase the speed for dial-up Internet connections. Most browsers support gzipped content, so Web pages appear as normal, but as they are only a fraction of their original page size, pages are much quicker to load. Even for browsers that don't support it, hints how to overcome it using SSH port forwarding are included. Images are on average one third smaller with only marginal visible image quality loss. It should be used with inetd/xinetd, but if you can't use them, a simple replacement "netd" is provided

Zomg: ZOMG is a console-based Libre.fm client written in Z-Shell. It can submit the music tracks you play to libre.fm via the Audioscrobbler protocol, and it can play libre.fm radio stations.

ZoneCheck: ZoneCheck is intended to help solve DNS misconfigurations or inconsistencies that are usually revealed by an increase in the latency of the application.
