If you are a broadband or dial-up user who doesn't have a firewall script, you need to get one to protect yourself. AutoFW is intended to help you do that with no hassles. Many people when connecting to the internet need a firewall script made for them so they can surf the net without being susceptible to various attacks. Most, if not all (until now :-), of the existing scripts are written for a large range of requirements and require some tweaking to make them work for a specific user. However many users do not know which parameters to fill in the script config file. AutoFW intends to provide a simple firewall script that you just need to fire and forget. You make sure to run it on computer start-up or just before connecting to the net, and it will detect network condition and setup appropriate firewall rules for you. In order to be "smart" AutoFW has to be limited, the current scope of AutoFW are standard broadband connections, it will also cover dial-up users and stand-alone servers.

The software is no longer currently being developed; the authors suggests the program SwiftSurf in place of bannerkiller.
BasE91
'basE91' is an advanced method for encoding binary data as ASCII characters. It is similar to UUencode or base64, but is more efficient. The overhead produced by basE91 depends on the input data. It amounts at most to 23% (versus 33% for base64) and can range down to 14%, which typically occurs on 0-byte blocks. This makes basE91 very useful for transferring larger files over binary insecure connections like e-mail or terminal lines.

CURL
curl offers a busload of useful tricks like proxy support, user authentication, ftp upload, HTTP post, SSL (https:) connections, cookies, file transfer resume and more. As you will see below, the amount of features will make your head spin! You can specify any amount of URLs on the command line. Urls can be fetched in a sequential manner in a specified order. If you specify URL without protocol:// prefix, curl will attempt to guess what protocol you might want. It will then default to HTTP but try other protocols based on often-used host name prefixes. For example, for host names starting with "ftp." curl will assume you want to speak FTP. Curl will attempt to re-use connections for multiple file transfers, so that getting many files from the same server will not do multiple connects / handshakes. This improves speed. Of course this is only done on files specified on a single command line and cannot be used between separate curl invokes.

Cloudgizer is a tool for building web applications as Apache modules in C language enhanced with simple markup, with emphasis on performance, small-footprint, and more productive and safer programming in C. It combines the ease of scripting with the power of C, improving the resource utilization for cloud applications. The programmer writes simple markup language mixed with C code, which is then translated entirely into C code and compiled natively as Apache module. The resulting application is fast and takes less memory, as there are no interpreters or virtual machines. Features include easy markups to use MariaDB database, HTML input parameters, cookies, simpler outputting of web pages, files storage and manipulation, encryption, encoding, program execution, web calls, safer and easier string manipulation etc. - the list is too long to place in one sentence. Overall Cloudgizer does a lot of stuff for you that you'd otherwise need to do yourself. A memory garbage collection system and memory overwrite/underwrite detection comes in handy for program stability. The same goes for string and memory handling markups to help write applications that won't crash. Also included is an application packaging system and an automated application installer. This makes rollout of products and release cycle more manageable. Cloudgizer source files have extension .v. Cloudgizer pre-compiler (cld program) will turn your .v files into .c files, ready for compilation as pure C programs. Then, your program will be compiled and linked with Apache web server on RH/Centos systems. It links with Apache as an Apache module in a "prefork" configuration. It does the work of communicating with Apache, and it makes it easier to write high-performance/small-footprint web programs in C. Cloudgizer is not designed to be thread-safe as it works in a "prefork" configuration of Apache. You can also build command-line programs. The same program can serve as both command-line utility and a web program linked with Apache. Cloudgizer works with RedHat/Centos 7 operating system, Apache web server and mariaDB database.

Cowloop
The cowloop-driver is a copy-on-write loop driver (block device) which can be used on top of any other block driver. It shields the lower driver from any write access and diverts all write-accesses to an arbitrary regular file, called the cowfile. When a modified block is read again later on, the cowloop-driver gets the block from the cowfile, while non-modified blocks are obtained from the original read-only device. This lets block-devices be used in a read-write fashion without modifying the underlying block-device itself.
CrawlTrack
CrawlTrack is a script, which makes it possible to follow the search-engines crawlers and spiders visits on your website.

Decentraleyes
Protects you against tracking through "free", centralized, content delivery. It prevents a lot of requests from reaching networks like Google Hosted Libraries, and serves local files to keep sites from breaking. Complements regular content blockers. Technical Information - Supported Networks: Google Hosted Libraries, Microsoft Ajax CDN, CDNJS (Cloudflare), jQuery CDN (MaxCDN), jsDelivr (MaxCDN), Yandex CDN, Baidu CDN, Sina Public Resources, and UpYun Libraries. - Bundled Resources: AngularJS, Backbone.js, Dojo, Ember.js, Ext Core, jQuery, jQuery UI, Modernizr, MooTools, Prototype, Scriptaculous, SWFObject, Underscore.js, and Web Font Loader. FAQ If you're using uMatrix, Edit in and Commit these lines to My rules in the Dashboard: (Please note that each line must also START with a '*' character but this Wiki is broken and does not allow to render this properly!)
  • ajax.aspnetcdn.com script allow
  • ajax.googleapis.com script allow
  • ajax.microsoft.com script allow
  • cdn.jsdelivr.net script allow
  • cdnjs.cloudflare.com script allow
  • code.jquery.com script allow
  • lib.sinaapp.com script allow
  • libs.baidu.com script allow
  • upcdn.b0.upaiyun.com script allow
  • yandex.st script allow
  • yastatic.net script allow
Note: Decentraleyes currently only bundles scripts, and if you want other resources to load you need to change script in the above rules to * and disable "Block requests for missing resources" in the Decentraleyes preferences. This will however result in network requests to these CDNs. If you use uBlock0 it shouldn't normally block these resources, but if you enable Advanced mode you might have a rule to block third-party scripts by default. Unlike with uMatrix we can't whitelist only scripts for individual hosts, but you can still control whether other resources are loaded with "Block requests for missing resources" in the Decentraleyes preferences. We also have the ability to let normal filtering take place as opposed to completely whitelisting everything from these domains: (Please note that each line must also START with a '*' character but this Wiki is broken and does not allow to render this properly!)
  • ajax.aspnetcdn.com * noop
  • ajax.googleapis.com * noop
  • ajax.microsoft.com * noop
  • cdn.jsdelivr.net * noop
  • cdnjs.cloudflare.com * noop
  • code.jquery.com * noop
  • lib.sinaapp.com * noop
  • libs.baidu.com * noop
  • upcdn.b0.upaiyun.com * noop
  • yandex.st * noop
  • yastatic.net * noop
With these rules, uBlock0 in Advanced mode will behave as in "normal" mode for these particular CDNs, which is usually what you want, but if you prefer you can change noop above to allow to ensure nothing from Decentraleyes is blocked.

Indexes won't prevent external mailbox updates, so Dovecot is still fully compatible with standard Maildir and mbox formats. There's also a fully featured POP3 server included.
Drall
Drall is a script which lets users access directories and files remotely without using insecure FTP and telnet. It lets the user treat the remote file system as if it was on their local hard disk through a normal Web browser. The interface resembles the well known Midnight Commander. Single or dual-panel views makes it easy to see an overview of the file system and the modular design means you only use the features you need.
Drbd
'drbd' is a block device for building high-availability clusters. DRBD takes over the data, writes it to the local disk and sends it to the other host. On the other host, it takes it to the disk there. The other components needed are a cluster membership service, which is supposed to be heartbeat, and an application that works on top of a block device (ie, a filesystem and fsck). Each device has either a 'primary' or 'secondary' state. The application should run and access the device on the node with the primary device. Every write is sent to the local 'lower level block device' and to the node with the device in 'secondary' state. The secondary device then writes the data to its lower level block device. If the primary node fails, heartbeat is switching the secondary device into primary state and starts the application there. If the failed node comes up again, it is a new secondary node and will synchronise its content to the primary node whithout interruption of service in the background. Only those parts of the device that actually have been changed will resync.

EPICS
'EPICS' is a software infrastructure for building distributed control systems to operate devices such as particle accelerators, large experiments and major telescopes. These systems comprise tens or hundreds of computers, networked together so they can communicate and provide control and feedback of the various parts from a control room, or remotely over the Internet. EPICS uses Client/Server and Publish/Subscribe techniques to communicate between the various computers. Most servers (called Input/Output Controllers or IOCs) perform real-world I/O and local control tasks, and publish this information to clients using the Channel Access (CA) network protocol. CA is specially designed for the kind of high bandwidth, soft real-time networking applications that EPICS is used for, and is one reason why it can be used to build a control system comprising hundreds of computers.

FFPF
This is a candidate for deletion: Links broken. From the maintainer "This was a research project from 2004 [1]. It is long dead now. It's probably best to remove the entry". Poppy-one (talk) 14:23, 29 July 2018 (EDT) The fairly fast packet filter (FFPF) adds many new features to existing filtering solutions. It is designed for high speed by pushing computationally intensive tasks to the kernel or to network processors, and by minimising packet copying. Also, since it provides a richer programming language and explicit extensibility, it is more flexible than existing approaches. Using its extensibility, the language can even be used as a meta- filter to "script" together filters from other approaches.

Filetea
FileTea is a simple way to send files among different users. FileTea functions as a web server. Users can drag files into their web browser and a URL will be generated for each one. Those URLs can be sent to other people, who will be able to start downloading the files immediately. An HTML5 capable browser is required in order to share the files, but any HTTP client can download them, including command-line tools such as curl or wget. Files are sent through the server, but no data is stored there: FileTea is only used to route the traffic. This also means that there's no limit to the size of shared files. The service is anonymous and does not require user registration. Since it's completely web-based, it works in networks with proxies, firewalls, etc., as long as all users can reach the FileTea server. A demonstration server is provided at https://filetea.me
Finger 2
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(old) 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(old) Finger follows the finger "protocol" (rules for communication) in responding to simple requests, since this protocol is siple. 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.
Fingerd
This is a much updated version of Mike Shanzer's fingerd-1.3. It is almost completely rewritten, well-debugged (i.e., more secure), and quite configurable. It supports ACLs, a message-of-the-day file, the ability to run programs for given user-IDs, and a full set of command-line options that make it mostly compatible with modern BSD versions. It is portable, uses GNU Autoconf and GNU Automake for builds, and it comes with a ready-to-use BSD makefile too.

Fractal
Fractal is a Gtk+ Matrix.org client written in Rust. Come to talk with us in Matrix: https://matrix.to/#/#fractal-gtk:matrix.org Main repository: https://gitlab.gnome.org/World/fractal/ How to Build: You need meson and ninja to build this project. Rust and cargo are also needed. ./configure --prefix=/usr/local make sudo make install On MacOS, you will need to: brew install gtk3+ dbus bash
  1. empirically needs 3.22.19 or later of gtk3+
  2. ...and run configure as:
/usr/local/bin/bash -c ./configure --prefix=/usr/local You may also need to comment out the notification.show block in ./fractal-gtk/src/app.rs as apparently notification.wait_for_action is missing on MacOS. The origin of Fractal: This project is based on ruma-gtk https://github.com/jplatte/ruma-gtk Instead of using RUMA Client, Fractal calls directly to the matrix.org REST API. The first version of this project was called guillotine, based on french revolution, in relation with the Riot client name, but it's a negative name so we decide to change for a math one. The name Fractal was proposed by Regina Bíró.
Free Realty
Free Realty is primarily designed for real estate agents and offices to list properties on the internet. With Free Realty the end user does not need to be fluent in web page design.
Free S WAN
GNU/Linux FreeS/WAN is an implementation of IPSEC (Internet Protocal SECurity) and IKE for GNU/Linux systems. It uses strong cryptography to provide both authentication and encryption; authentication ensures that packets are from the right sender and have not been altered in transit, and encryption prevents unauthorised reading of packet contents. These services allow you to build secure tunnels through untrusted networks. Everything passing through the untrusted net is encrypted by the IPSEC gateway machine and decrypted by the gateway at the other end. The result is Virtual Private Network or VPN. This network is effectively private even though it includes machines at several different sites connected by the insecure Internet. Several companies are co-operating in the Secure Wide Area Network (S/WAN) project to ensure that products will interoperate. There is also a VPN Consortium fostering cooperation among companies in this varea. The primary objective is to help make IPSEC widespread by providing source code which is freely available, runs on a range of machines including ubiquitous cheap PCs, and is not subject to US or other nations' export restrictions.
Free Software Directory search
The Free Software Directory is a catalog of useful free software that runs under free operating systems. FSF staff and volunteers work together to collect detailed information about free software programs and organize it in a clear and accessible format. This is a search plugin for the Free Software Directory. A program is free software if the program's users have the four essential freedoms: 1) The freedom to run the program as you wish, for any purpose (freedom 0). 2) The freedom to study how the program works, and change it so it does your computing as you wish (freedom 1). Access to the source code is a precondition for this. 3) The freedom to redistribute copies so you can help your neighbor (freedom 2). 4) The freedom to distribute copies of your modified versions to others (freedom 3). By doing this you can give the whole community a chance to benefit from your changes. Access to the source code is a precondition for this.
FreeWAF
FreeWAF is a reverse proxy WAF built using the OpenResty stack. It uses the Nginx Lua API to analyze HTTP request information and process against a flexible rule structure. FreeWAF is distributed with a ruleset that mimics the ModSecurity CRS, as well as a few custom rules built during initial development and testing. FreeWAF was initially developed by Robert Paprocki for his Master's thesis at Western Governor's University.
Freebeltane
Beltane v1 was distributed under the GPL. Unfortunately, its authors have decided to distribute Beltane v2 under a non-free license (no redistribution), and their web pages prominently mention v2. Thus, this project starts with Beltane v1, and sticks to free software references. Samhain, the package for which it is a frontend, remains free. As of November 12, 2004, this project has no maintainer. Please email (karl@gnu.org) if you are interested in becoming the maintainer; the original authors appear to be making only occasional bug fixes to v1 at this point.

Freenet
Freenet allows efficient distribution of information over the Internet without fear of censorship. Freenet is completely decentralized: there is no entity in control of, or essential to, Freenet so there's no central point that would collapse the entire system if attacked. It is hard to remove single pieces of information from Freenet, since it's difficult to determine which computer is storing any given piece of information. Trying to determine where information is stored results in that information spreading to other nodes within Freenet (usually the opposite of what you want to happen). Both authors and readers of information on Freenet can remain anonymous if they wish. Freenet also employs intelligent routing and caching, meaning that it learns to route requests more efficiently, automatically mirrors popular data, makes network flooding almost impossible, and moves data to where it is in greatest demand.

GMM
The Guarded Memory Move tool is useful for studying buffer overflows and catching them together with a "good" stack image. Once a stack overflow has been exploited, the back trace is already gone, as is information about parameters and local variables that are very important in understanding how the attacker is working out the exploit. The GMM library uses dynamic function call interception to catch the most common functions that attackers use to exploit stack buffers. It uses the LD_PRELOAD capability and offers two services: first, it avoids buffer overflow to allow the attacker to execute shell-code on your machine. Second, where an exploit is detected, it saves the stack content and triggers a segmentation fault. The resulting core dump has the necessary information to debug the exploit and fix the software.

Garpd Heckert gnu.tiny.png
Broadcasts Gratuitous ARPs for a list of MAC address <-> IP address mappings on specified interfaces at regular intervals. A gratuitous ARP request is an AddressResolutionProtocol request packet where the source and destination IP are both set to the IP of the machine issuing the packet and the destination MAC is the broadcast address ff:ff:ff:ff:ff:ff. Ordinarily, no reply packet will occur. Gratuitous ARP reply is a reply to which no request has been made. Gratuitous ARPs are useful to update ARP tables of switches, routers and other hosts to route packets to a designated IP address. Garpd was developed as a part of GNU FreeIPMI project. Some of the IPMI implementations doesn't implement GARP broadcast functionality in their NICS. When the host OS is down and BMC is active listening for IPMI packets on the NIC, it needs to inform other switches/routers to route packets to its NIC. Because Garpd is useful for other purposes too, we decided to make it as a separate project.

Any model that includes ActiveModel::Validations should work. Our aim is to be database and mapper agnostic, so if it doesn't work for you, open an issue. Humanizer works with Rails 3 and 4.
I2P
The Invisible Internet Project (I2P) is a project to build, deploy, and maintain a network supporting secure and anonymous communication. People using I2P are in control of the tradeoffs between anonymity, reliability, bandwidth usage, and latency. There is no central point in the network on which pressure can be exerted to compromise the integrity, security, or anonymity of the system. The network supports dynamic reconfiguration in response to various attacks, and has been designed to make use of additional resources as they become available. Of course, all aspects of the network are open and freely available. Unlike many other anonymizing networks, I2P doesn't try to provide anonymity by hiding the originator of some communication and not the recipient, or the other way around. I2P is designed to allow peers using I2P to communicate with each other anonymously — both sender and recipient are unidentifiable to each other as well as to third parties. For example, today there are both in-I2P web sites (allowing anonymous publishing / hosting) as well as HTTP proxies to the normal web (allowing anonymous web browsing).

IceCat/FreeSpeechMe
FreeSpeechMe is a Free Software plug-in for IceCat that allows people to effortlessly view Dot-Bit websites. It works on GNU/Linux and Windows. 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/
