[[Concept:Network-hookup]]

Airhook: Airhook is a reliable data delivery protocol, like TCP. Unlike TCP, Airhook gracefully handles intermittent, unreliable, or delayed networks. Other features include session recovery, queue control, and delivery status notification. Airhook is useful for keeping connections running over bad wireless networks (like CDPD), intermittent dial-up connections, and any other network that doesn't work very well. The implementation includes a TCP proxy (so you can use HTTP, SSH, etc.) and a protocol library for applications that want more control (real-time media delivery, games, etc).

Alexis FTP (aftp): aftp is an FTP library and a background FTP tool. The aftp tool is a good example on how to use the library. You need FTP functionality in your software? Use the aftp library!

Ambassador: Ambassador is a fork of the ChatZilla IRC client built upon the Unified XUL Platform. It features a simple, straighforward interface with a number of options for customization and extensibility. It is available as an add-on compatible with other applications built upon UXP, and as a stand-alone package that can be installed and run independently of a browser.

Anastasis ,: Anastasis is a key recovery system that allows the user to securely deposit shares of a core secret with an open set of escrow providers, to recover it if the secret is lost. The core secret itself is protected from the escrow providers by giving each provider only part of the information, and additionally by encrypting it with an identity-based key unknown to the providers.

It features support for HTTPS, virtual hosting, CGI, SSI, IPv6, easy scripting and database integration, request/response filtering, many flexible authentication schemes, and more.

Aplakons: Aplakons allows you to build a sheets schema to organize activities to be followed by registered users. You can configure sets of sheets to customize each one’s activities to follow. You prepare a repository of sheets (as concrete activities), and after you order them in different arrays. The arrays can be assigned to users as activity plans. For example, a whole diet (array) based on cooking recipes (activities).

Arping: Arping is an ARP level ping utility. It's good for finding out if an IP is taken before you have routing to that subnet. It can also ping MAC addresses directly.

Async-timeout: Used in cases where part of the software being developed is time-sensitive, so that the code block doesn't wait too much time for certain event to complete.

Aumonet: Detects network and SSH server availability, mounts registered accesses and maintains them mounted accross network changes and interruptions.

AuthzForce: The AuthzForce project provides an Attribute-Based Access Control (ABAC) framework compliant with the OASIS XACML standard v3.0, that mostly consists of an authorization policy engine and a RESTful authorization server. It was primarily developed to provide advanced access control for Web Services or APIs, but is generic enough to address all kinds of access control use cases. You can use AuthzForce in two ways depending on your needs: Java API: AuthzForce provides a XACML PDP (Policy Decision Point) engine as a Java library so that applications can instantiate and use an embedded XACML PDP easily with Java. This API is provided by AuthzForce Core. Web API: AuthZForce provides a multi-tenant HTTP/REST API to PDPs and PAPs (Policy Administration Points) that web clients can call to manage policies, request authorization decisions, etc. This API is provided by AuthzForce Server.

Autohosts: Hosts files will reroute unwanted traffic from ad farms, behavioral tracking firms and malware sites to a blackhole; routing to 0.0.0.0 (localhost; your PC) when a request is made to a URL on the blacklist. Which means any traffic that would have left your system for that destination, is sent inward, to your localhost and then abandoned. Despite what some may suggest, hosts files are not "1980s technology" and still very useful today, as an additional layer of security. Hosts file are a useful redundancy when coupled with ad blockers like uBlock Origin and uMatrix - while debugging or 'Temporarily Allow All on this Site' with Noscript can open you up to underlying attacks or privacy intrusions. In-browser filters won't protect you if the browser itself is phoning home. If you have an up-to-date hosts file, the risk is severely lessened. Auto Hosts will automate the setup process for maintaining an up to date hosts file, by: - Installing a weekly cronjob to pull fresh/updated copies of hosts lists (default is every Sunday at 7:22pm) (Default custom_filters and firefox-includes) source appends Facebook trackers, Linkedin ads, Google fonts, Firefox telemetry and other harvester sites that curated lists for whatever reason, have not added to their blacklists - Refreshes DNS to instantiate the re-routed changes (Mac Only) If Devdom is installed, append all local virtualhosts (if it is installed - it is -not- a requirement! Autohosts does a conditional check to ensure your dev environment doesn't break if you're using Devdom. Read the code.) - Uninstall offers the ability to revert to a fresh hosts file and undo any changes made by Autohosts; a backup will be copied to /tmp - Add custom blacklists, whitelists and host sources from ~/autohosts on your desktop

Avahi: Avahi is a system which facilitates service discovery on a local network via the mDNS/DNS-SD protocol suite. This enables you to plug your laptop or computer into a network and instantly be able to view other people who you can chat with, find printers to print to or find files being shared. Compatible technology is found in Apple MacOS X (branded "Bonjour" and sometimes "Zeroconf"). Avahi is primarily targetted at GNU/Linux systems and ships by default in most distributions. It is not ported to Windows at this stage, but will run on many other BSD-like systems. The primary API is D-Bus and is required for usage of most of Avahi, however services can be published using an XML service definition placed in /etc/avahi/services. See also the nss-mdns project, which allows hostname lookup of *.local hostnames via mDNS in all system programs using nsswitch

Conversations.im: Conversations is a Jabber/XMPP client for Android 5.0+ smartphones that has been optimized to provide a unique mobile experience. A port to iOS is envisaged in the medium-term future. Conversations allows you to easily send images, show if your contact has received and read your message, permit dynamic history and handles multiple devices (especially sync with desktop clients), allow you to create group chats and support one-to-one Audio/Video calls ! And thanks to the XMPP Protocol (that is a push protocol) you battery life is safe. Conversations also does not require a Google Account or specifically Google Cloud Messaging (GCM). Using the XMPP federated protocol, you can freely choose a trustworthy server (your own if you want) for yourself while still chatting with contacts that are using other servers. The communication between Conversations and the XMPP server as well as the communication between the individual servers is TLS encrypted. This way, not only your messages are safe but more importantly it is impossible for an outside attacker to intercept your meta data (with whom you are chatting) without attacking your server first. On top of that, Conversations gives you the choice to enable one of two end-to-end encryption mechanisms. The first one is OMEMO, a state of the art multi-end-to-multi-end encryption method which is very easy to setup and gives you forward secrecy and plausible deniability. For backwards compatibility reasons Conversations also supports OpenPGP.

Cspeedtest: Command line (CLI) network speed test for GNU/Linux servers, using libncurses to estimate network throughput between you and your server over an existing ssh connection. Works on any client platform that has a terminal that supports curses (e.g. iOS, Android, Mac OS, Windows, GNU/Linux, etc). Network speed is measured by writing screenfuls of random characters to the terminal, using the resulting framerate to estimate the throughput. It takes advantage of the implicit communication between the server and your terminal to measure network performance without any client software beyond the terminal you already have. Note: This software just needs to be installed on the server.

Curlftpfs: This is a file system client based on the FTP File Transfer Protocol.

Cyberduck CLI: The universal file transfer tool duck which runs in your shell on GNU/Linux and OS X or your Windows command line prompt. Edit files on remote servers, download, upload and copy between servers with FTP, SFTP or WebDAV plus support for cloud storage deployments.

DMBCS Embedded C++ HTTP Server: At DMBCS we like to do things in certain ways: all our code takes the form of C++17 (or, lately, C++20) libraries built with GNU autotools, providing user interaction through HTTP/HTML5/CSS3/EcmaScript web interfaces. It is thus a common requirement that our code links against a library of classes which implement the HTML paradigm and provide the TCP/IP plumbing to allow applications to easily take the form of self-contained web servers. At DMBCS we use NGINX at top-level to coordinate the set of such micro-servers which make up a complete web site. The library has been under constant development for over twenty years (yes, really), and in heavy production use. The code-base hasnʼt quite been brought up to our expectations of full production-quality code yet (it has always been a project on the side of other things), and so we still regard it as beta-quality software. We expect this situation to change in the near future.

DNSleak: DNSleak inspects DNS packets on the local network interface to detect leaks. Unlike web-based solutions, it works at the local computer level. No third party servers are used and DNS leak result is a true/false response.

Dhcpcd: a DHCP and DHCPv6 client. It's also an IPv4LL (aka ZeroConf) client. In layman's terms, dhcpcd runs on your machine and silently configures your computer to work on the attached networks without trouble and mostly without configuration. If you're a desktop user then you may also be interested in Network Configurator (dhcpcd-ui) which sits in the notification area and monitors the state of the network via dhcpcd. It also has a nice configuration dialog and the ability to enter a pass phrase for wireless networks. dhcpcd may not be the only daemon running that wants to configure DNS on the host, so it uses openresolv to ensure they can co-exist.

Dhlan: dhlan scans and updates to /etc/hosts with a MAC:name table. It's the most simple and easy replacement of DNS server, to customize named localization of computers, printers or any other device accross any Local Area Network. For example, 2 laptops can maintain valid name-to-ip although network changes.

Dino (instant messenger): Dino is a modern open-source chat client for the desktop. It focuses on providing a clean and reliable Jabber/XMPP experience while having your privacy in mind. It supports end-to-end encryption with OMEMO and OpenPGP and allows configuring privacy-related features such as read receipts and typing notifications. Dino fetches history from the server and synchronizes messages with other devices.

Dmbcs-kraken-api: Kraken is a virtual currency exchange, which also handles fiat (real) currency amounts. Subscribers to the service have an account with associated funds attached. The web site (www.kraken.com) provides the user with an account overview (i.e. current balance), currency-pair exchange market status (history of prices and current order book), and the means to place entries on the order book; bids for a currency which can be immediately met with orders to sell the currency are automatically transacted, with the Kraken site taking a small and variable cut of the deal. Kraken also provide a stateless, web-based API by which all of the above actions can be undertaken programmatically. This is fully open, and described at the Kraken exchange web site. The DMBCS client-side C++ library implements all features of the API in a fully encapsulated C++ class, allowing users to implement algorithmic or robotic trading and dynamic exchange modelling.

Dnsmasq: Dnsmasq is a lightweight DNS forwarder and DHCP server. It is designed to provide DNS and optionally, DHCP, to a small network. It can serve the names of local machines which are not in the global DNS. The DHCP server integrates with the DNS server and allows machines with DHCP-allocated addresses to appear in the DNS with names configured either in each host or in a central configuration file. Dnsmasq supports static and dynamic DHCP leases and BOOTP/TFTP for network booting of diskless machines.

Docassemble: docassemble is a system for guided interviews and document assembly. It provides a web application that conducts interviews with users. After each interview, docassemble generates documents in various formats based on user input and preconfigured templates. Though the name emphasizes the document assembly feature, docassemble interviews do not need to assemble a document; they might submit an application, direct the user to other resources on the internet, store user input, interact with APIs, or simply provide the user with information. docassemble was created by a lawyer/computer programmer for purposes of automating the practice of law, but it is a general-purpose platform that can find applications in a variety of fields.

Fdm (mail agent): fdm (fetch/filter and deliver mail) is a program designed to fetch mail from POP3 or IMAP servers, or receive local mail from stdin, and deliver it in various ways depending on a user-supplied ruleset. Mail may be filtered based on whether it matches a regexp, its size or age, or the output of a shell command. It can be rewritten by an external process, dropped, left on the server or delivered into maildirs, mboxes, to a file or pipe, or any combination. fdm is designed to be lightweight but powerful, with a compact but clear configuration syntax. It is primarily designed for single-user uses but may also be configured to deliver mail in a multi-user setup. In this case, it uses privilege separation to minimize the amount of code running as the root user.

Finger: A modern computing facility consists of one user per host, and many hosts per site. To find out about logged on users at another site you must query each host to find out about an individual user. With GNU Finger, a single host is designated the finger "server" host and collects information about who is logged on to other hosts at that site. A user then needs to query only the server host, instead of each host at that site. GNU Finger follows the finger "protocol" (rules for communication) in responding to simple requests, since this protocol is simple. But it can also implement another protocol that lets two finger programs exchange information in a predetermined way; this allows faster and wider bandwidth communication.
