[[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.

Dot-Bit (.bit) is a new top-level domain that, unlike Dot-Com, Dot-Net, Dot-UK, etc., is NOT controlled by any government or corporation. FreeSpeechMe works over the distributed blockchain of the inexpensive cryptocurrency, Namecoin (a derivative of BitCoin). Namecoin is not generally traded as currency. It exists primarily for the purpose of decentralized DNS. Domains currently cost about 10 cents US of Namecoin to register. Before FreeSpeechMe, viewing Dot-Bit websites required changing DNS settings, and using non-vetted public DNS servers. FreeSpeechMe doesn't require changing DNS settings, so it is much more secure. Newly registered Dot-Bit websites can be viewed within three hours worldwide with FreeSpeechMe. IP or Nameserver update changes to an existing Dot-Bit website are viewable worldwide within 40 minutes. This isn't just "a plug-in." FreeSpeechMe, Dot-Bit and Namecoin are a complete new Internet ecosystem, free of the constraints of ICANN and the like. Please see tech FAQ for full list of improvements and implementations we're planning on for FreeSpeechMe and Namecoin: http://www.freespeechme.org/advanced-faq/

Ipfs: pleas add

Iproute2: Iproute2 is a collection of utilities for controlling TCP / IP networking and traffic control in GNU/Linux. It is currently maintained by Stephen Hemminger <stephen@networkplumber.org>. The original author, Alexey Kuznetsov, is well known for the QoS implementation in the Linux kernel. Most network configuration manuals still refer to ifconfig and route as the primary network configuration tools, but ifconfig is known to behave inadequately in modern network environments. They should be deprecated, but most distros still include them. Most network configuration systems make use of ifconfig and thus provide a limited feature set. The /etc/net project aims to support most modern network technologies, as it doesn't use ifconfig and allows a system administrator to make use of all iproute2 features, including traffic control. iproute2 is usually shipped in a package called iproute or iproute2 and consists of several tools, of which the most important are ip and tc. ip controls IPv4 and IPv6 configuration and tc stands for traffic control. Both tools print detailed usage messages and are accompanied by a set of manpages.

Jdresolve: Resolves IP addresses to hostnames. Any file format is supported, including those where the line does not begin with the IP address. One of the strongest features of the program is the support for recursion, which can drastically reduce the number of unresolved hosts by faking a hostname based on the network that the IP belongs to. DNS queries are sent in parallel, which means that you can decrease run time by increasing the number of simultaneous sockets used (given a fast enough machine and available bandwidth). By using the database support, performance can be increased even further, by using cached data from previous runs.

Lemmy: Lemmy is similar to sites like Reddit, Lobste.rs, Raddle, or Hacker News: you subscribe to forums you're interested in, post links and discussions, then vote, and comment on them. Behind the scenes, it is very different; anyone can easily run a server, and all these servers are federated (think email), and connected to the same universe, called the Fediverse. For a link aggregator, this means a user registered on one server can subscribe to forums on any other server, and can have discussions with users registered elsewhere. The overall goal is to create an easily self-hostable, decentralized alternative to reddit and other link aggregators, outside of their corporate control and meddling. Each lemmy server can set its own moderation policy; appointing site-wide admins, and community moderators to keep out the trolls, and foster a healthy, non-toxic environment where all can feel comfortable contributing.

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.\

Vthrottle: 'vthrottle' is an implementation of an SMTP throttling engine for Sendmail. It lets sysadmins control how much email users and hosts may send, hindering the rapid spread of viruses, worms, and spam. Exceptions can be made via a whitelist mechanism, which can be generated manually or with the included tool 'vmeasure'. 'vthrottle' tells the misbehaving client to hold on to the deferred mail and resend it later. 'vthrottle' evaluates mail transactions at the connection, the HELO (or EHLO) statement, and the stated source address of the mail. For each of these, a list is traversed and the observed time interval between observations is evaluated. If the observed interval is shorter than the policy interval, the mail is blocked by sending a failure reply code to the SMTP client; the message is then queued. Because 'vthrottle' uses libmilter, it will not work with other MTAs, only with sendmail.

This program is developed using HTML5 which allows it to run within a web browser and requires no installation on to the user's hard drive.

Websocket: Pluggable transports are tools that transform a stream of application traffic into a different format on the network. This helps to bypass network-level censorship. This package contains a server transport plugin that accepts connections transformed to look like the websocket protocol. This is typically used to enhance systems like Tor, to provide service even to censored users. See flashproxy-client for a corresponding client transport plugin, meant for users to bypass censorship, that is compatible with the websocket protocol that this package expects. (The source package also contains a websocket-client transport plugin, but this is just a demo that is less effective than flashproxy-client, and not meant to be used in real situations.)

While initially released for the Linux kernel, it is now a cross-platform project. Some users consider WireGuard to already be the most secure and easiest to use among all of the VPN solutions.

Wmget: 'wmget' lets you run multiple downloads and monitor or control them from within a dockapp. This makes it easy to see their progress without keeping extra windows open. 'wmget' uses the libcurl library to support HTTP and FTP downloads. It will work with any window manager that supports dockapps.

Wograld: Wograld is a 2d 45 degree isometric multi-player online rpg. It is in development with many gameplay features not yet implemented. It is a fork of crossfire with mostly redone graphics and some gameplay changes to make it more fun and newbie friendly.

Wolfssl: wolfSSL is an embedded SSL/TLS software library designed for resource constrained environments. wolfSSL has implemented the Secure Sockets Layer (SSLv3 only) and Transport Layer Security (TLSv1,TLSv1.1, TLSv1.2, and TLSv1.3). wolfSSL offers a highly configurable list of features. Dependant upon functionality and speed requirements, wolfSSL can take up as little as 21k on your device. wolfSSL's wolfCrypt module is FIPS certified if you need a FIPS solution.

Wpa supplicant: wpa_supplicant is a WPA Supplicant for GNU/Linux, BSD, Mac OS X, and Windows with support for WPA and WPA2 (IEEE 802.11i / RSN). It is suitable for both desktop/laptop computers and embedded systems. Supplicant is the IEEE 802.1X/WPA component that is used in the client stations. It implements key negotiation with a WPA Authenticator and it controls the roaming and IEEE 802.11 authentication/association of the wlan driver. wpa_supplicant is designed to be a "daemon" program that runs in the background and acts as the backend component controlling the wireless connection. wpa_supplicant supports separate frontend programs and a text-based frontend (wpa_cli) and a GUI (wpa_gui) are included with wpa_supplicant. wpa_supplicant uses a flexible build configuration that can be used to select which features are included. This allows minimal code size (from ca. 50 kB binary for WPA/WPA2-Personal and 130 kB binary for WPA/WPA2-Enterprise without debugging code to 450 kB with most features and full debugging support; these example sizes are from a build for x86 target).

WxSFTP: wxSFTP is a simple, easy to use and portable SFTP client. With simple we mean that the program will have only the main features needed. The structure consists of a two panel window, one for the local filesystem and another for the remote filesystem. To be easy to use we are developing a graphical client that will be HIG compliant. Portability is reached with language (python) and graphical library (wxpython).

Wyatt-netsuite: Interface plugin for connection Netsuite to wyatt communications base.

X ITE: X_ITE is a new WebGL X3D Browser engine entirely written in JavaScript and uses WebGL for 3D rendering. Authors can publish X3D source online within an HTML5 page with X_ITE that works with Web browsers without prior plugin installation. This gives X3D authors the ability to displays content in 3D, using WebGL 3D graphics technology to display X3D content in several different browsers across several different operating systems. Since X3D is backwardly compatible, X_ITE can also be used as a VRML viewer.

X-Road: X-Road is a standardised, cohesive, collaborative, interoperable, and secure data exchange layer that gives service providers an entirely new opportunity to make themselves visible in services directed at citizens, businesses, and civil servants. Creating entities that combine many different services and data sources is easy and cost-efficient.

X3dom: Integrate 3D content seamlessly into your webpage - the scene is directly written into the HTML markup. No Plugins needed.

XAXDEV: Private EVN for test

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.

Xllmnrd: xllmnrd is an independent LLMNR responder daemon (a.k.a. llmnrd) for IPv6 networks and currently supports GNU/Linux operating systems with plans to support others. It allows Microsoft Windows clients to get the IPv6 addresses of a server on the same local network without any DNS configuration and can supplement IPv4‐only NetBIOS name resolution provided mainly by Samba.

Xombrero: xombrero is a minimalist web browser with sophisticated security features designed-in, rather than through an add-on after-the- fact. In particular, it provides both persistent and per-session controls for scripts and cookies, making it easy to thwart tracking and scripting attacks. In addition to providing a familiar mouse-based interface like other web browsers, it offers a set of vi-like keyboard commands for users who prefer to keep their hands on their keyboard. The default settings provide a secure environment. With simple keyboard commands, the user can whitelist specific sites, allowing cookies and scripts from those sites. xombrero is light and has a very good performance when running over network connections, as SSH forwarded tunnels. The major features are: - Tabbed browsing; - Written entirely in C; - Based on Webkit and GTK3, with GTK2 compatibility; - Built with security in mind; - Minimal on-screen layout; - Cookie, javascript and plugin toggles and whitelists; - Browsing session data auto-saves in case of crash; - Simple integration with Tor and other web proxies; - vi-like default keybindings; - Mouse-less browsing; - Basic MIME support; - Seamless upgrade process; - DNS and link prefetch disabled by default; - Colorful address bar indicates HTTPS certificate status; - Control over user_agent presented to sites; - Download manager; - Text-based config file; - Bookmarks, i.e. favorites; - Printing, including to PDF.

Xtraceroute: Xtraceroute is a graphical version of the traceroute program, which traces the route your IP packets travel to their destination. It displays the routes on a rotating globe (you can also move the globe around) as a series of yellow lines between 'sites', shown as small balls of different colors.

YaCy: YaCy (Yet another Cyberspace) peers crawl the internet and share the results. This decentralized network does not store search queries and makes censorship impossible.

Yafc: YAFC is quite a powerful FTP client. It is a console interface to the FTP protocol. Some of the features are recursive transfers, nohup transfers, colored ls, cached directory listings, autologin and bookmarks, powerful aliases and extensive tab completion. It also has support for Kerberos authentication.

Yggdrasil: Yggdrasil is an early-stage implementation of a fully end-to-end encrypted IPv6 network. It is lightweight, self-arranging, supported on multiple platforms and allows pretty much any IPv6-capable application to communicate securely with other Yggdrasil nodes. Yggdrasil does not require you to have IPv6 Internet connectivity - it also works over IPv4. Although Yggdrasil shares many similarities with cjdns, it employs a different routing algorithm based on a globally-agreed spanning tree and greedy routing in a metric space, and aims to implement some novel local backpressure routing techniques. In theory, Yggdrasil should scale well on networks with internet-like topologies.

Yt-local: Provides a server to browse YouTube locally, thus eliminating the need to trust a third-party server to represent you. yt-local has an option to route most of the traffic through Tor and also does not require YouTube API keys.

Zebedee: Zebedee establishes an encrypted, compressed tunnel for TCP/IP or UDP data transfer between two systems. This protects telnet, ftp and X traffic from snooping. It has a small footprint, low wire protocol overhead, and gives significant traffic reduction by the use of compression.

Zebra: Zebra manages various IPv4 and IPv6 routing protocols. The latest version supports BGP4, BGP4+, OSPFv2, OSPFv3, RIPv1, RIPv2, and RIPng. Quagga, not an official GNU Package, is forked from Zebra.

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.

Zibawa: Zibawa integrates other free software to create a full stack IoT system, including device management, mqtt message intepreter and enrichment, stack management and monitoring, test messaging and stack configuration. Works with mqtt, amqp and http protocols. Currently interfaces with rabbitmq, influxDB, Grafana dashboards, openLDAP.

Zorp: Zorp is a new generation proxy firewall suite and as such its core architecture is built around today's security demands: it uses application level proxies, it is modular and component based, it uses a script language to describe policy decisions, it makes it possible to monitor encrypted traffic, it let's you override client actions, it let's you protect your servers with its built in IDS capabilities... The list is endless. It gives you all the power you need to implement your local security policy.
