FreeRADIUS is the most popular open source RADIUS server and the most widely deployed RADIUS server in the world. It supports all common authentication protocols , and the server comes with a PHP -based web user administration tool called dialupadmin . It is the basis for many commercial RADIUS products and services, such as embedded systems, RADIUS appliances that support network access control , and WiMAX . It supplies

160-455: A linker . The GNU system required its own C compiler and tools to be free software, so these also had to be developed. By June 1987, the project had accumulated and developed free software for an assembler , an almost finished portable optimizing C compiler ( GCC ), an editor ( GNU Emacs ), and various Unix utilities (such as ls , grep , awk , make and ld ). They had an initial kernel that needed more updates. Once

240-428: A negative or positive liberty . Due to their restrictions on distribution, not everyone considers copyleft licenses to be free. Conversely, a permissive license may provide an incentive to create non-free software by reducing the cost of developing restricted software. Since this is incompatible with the spirit of software freedom, many people consider permissive licenses to be less free than copyleft licenses. There

The list mostly describes distributions that are a combination of GNU packages with a Linux-libre kernel (a modified Linux kernel that removes binary blobs, obfuscated code, and portions of code under proprietary licenses) and consist only of free software (eschewing proprietary software entirely). Distributions that have adopted

The previous major release v2.2.x has entered the final phase of its lifecycle, and will now receive security fixes only A survey in 2006 showed that its user base totals 100 million people. Modules included with

480-514: A copy of the free application itself. Fees are usually charged for distribution on compact discs and bootable USB drives, or for services of installing or maintaining the operation of free software. Development of large, commercially used free software is often funded by a combination of user donations, crowdfunding , corporate contributions, and tax money. The SELinux project at the United States National Security Agency

560-401: A drop in revenue to the proprietary software industry by about $ 60 billion per year. Eric S. Raymond argued that the term free software is too ambiguous and intimidating for the business community. Raymond promoted the term open-source software as a friendlier alternative for the business and corporate world. GNU Project The GNU Project ( / ɡ n uː / )

640-547: A fee. The Free Software Foundation encourages selling free software. As the Foundation has written, "distributing free software is an opportunity to raise funds for development. Don't waste it!". For example, the FSF's own recommended license (the GNU GPL ) states that "[you] may charge any price or no price for each copy that you convey, and you may offer support or warranty protection for

720-447: A fee." Microsoft CEO Steve Ballmer stated in 2001 that "open source is not available to commercial companies. The way the license is written, if you use any open-source software, you have to make the rest of your software open source." This misunderstanding is based on a requirement of copyleft licenses (like the GPL) that if one distributes modified versions of software, they must release

800-484: A for-profit, commercial activity or not. Some free software is developed by volunteer computer programmers while other is developed by corporations; or even by both. Although both definitions refer to almost equivalent corpora of programs, the Free Software Foundation recommends using the term "free software" rather than " open-source software " (an alternative, yet similar, concept coined in 1998), because

880-468: A fully free (libre) GNU/Linux distribution. From the mid-1990s onward, with many companies investing in free software development, the Free Software Foundation redirected its funds toward the legal and political support of free software development. Software development from that point on focused on maintaining existing projects, and starting new projects only when there was an acute threat to

960-460: A result, any user who obtains the software legally has the same freedoms as the rest of its users do. The GNU Project and the Free Software Foundation sometimes differentiate between "strong" and "weak" copyleft. "Weak" copyleft programs typically allow distributors to link them together with non-free programs, while "strong" copyleft strictly forbids this practice. Most of the GNU Project's output

1040-559: A significant part in the development of the Internet, the World Wide Web and the infrastructure of dot-com companies . Free software allows users to cooperate in enhancing and refining the programs they use; free software is a pure public good rather than a private good . Companies that contribute to free software increase commercial innovation . "We migrated key functions from Windows to Linux because we needed an operating system that

1120-488: A small set of licenses. The most popular of these licenses are: The Free Software Foundation and the Open Source Initiative both publish lists of licenses that they find to comply with their own definitions of free software and open-source software respectively: The FSF list is not prescriptive: free-software licenses can exist that the FSF has not heard about, or considered important enough to write about. So it

1200-557: A version of GNU/Hurd that is suitable for production environments since the commencement of the GNU/Hurd project over 33 years ago. A stable version (or variant) of GNU can be run by combining the GNU packages with the Linux kernel , making a functional Unix-like system. The GNU project calls this GNU/Linux, and the defining features are the combination of: Within the GNU website, a list of projects

1280-455: Is a free software , mass collaboration project announced by Richard Stallman on September 27, 1983. Its goal is to give computer users freedom and control in their use of their computers and computing devices by collaboratively developing and publishing software that gives everyone the rights to freely run the software, copy and distribute it, study it, and modify it. GNU software grants these rights in its license . In order to ensure that

1360-617: Is an example of a federally funded free-software project. Proprietary software, on the other hand, tends to use a different business model, where a customer of the proprietary application pays a fee for a license to legally access and use it. This license may grant the customer the ability to configure some or no parts of the software themselves. Often some level of support is included in the purchase of proprietary software, but additional support services (especially for enterprise applications) are usually available for an additional fee. Some proprietary software vendors will also customize software for

1440-466: Is biased by counting more vulnerabilities for the free software systems, since their source code is accessible and their community is more forthcoming about what problems exist as a part of full disclosure , and proprietary software systems can have undisclosed societal drawbacks, such as disenfranchising less fortunate would-be users of free programs. As users can analyse and trace the source code, many more people with no commercial constraints can inspect

1520-471: Is computer software distributed under terms that allow users to run the software for any purpose as well as to study, change, and distribute it and any adapted versions. Free software is a matter of liberty , not price; all users are legally free to do what they want with their copies of a free software (including profiting from them) regardless of how much is paid to obtain the program. Computer programs are deemed "free" if they give end-users (not just

1600-535: Is consistent with the intended meaning unlike the term "Open Source". The loan adjective " libre " is often used to avoid the ambiguity of the word "free" in the English language , and the ambiguity with the older usage of "free software" as public-domain software. ( See Gratis versus libre . ) The first formal definition of free software was published by FSF in February 1986. That definition, written by Richard Stallman ,

1680-451: Is debate over the security of free software in comparison to proprietary software, with a major issue being security through obscurity . A popular quantitative test in computer security is to use relative counting of known unpatched security flaws. Generally, users of this method advise avoiding products that lack fixes for known security flaws, at least until a fix is available. Free software advocates strongly believe that this methodology

1760-483: Is laid out and each project has specifics for what type of developer is able to perform the task needed for a certain piece of the GNU project. The skill level ranges from project to project but anyone with background knowledge in programming is encouraged to support the project. The packaging of GNU tools, together with the Linux kernel and other programs, is usually called a Linux distribution (distro). The GNU Project calls

1840-463: Is like considering the practical advantages of not being handcuffed, in that it is not necessary for an individual to consider practical reasons in order to realize that being handcuffed is undesirable in itself. The FSF also notes that "Open Source" has exactly one specific meaning in common English, namely that "you can look at the source code." It states that while the term "Free Software" can lead to two different interpretations, at least one of them

1920-419: Is not covered by copyright law, such as software in the public domain , is free as long as the source code is also in the public domain, or otherwise available without restrictions. Proprietary software uses restrictive software licences or EULAs and usually does not provide users with the source code. Users are thus legally or technically prevented from changing the software, and this results in reliance on

2000-443: Is not endorsed by the FSF and does not use Linux-libre, it is also a popular distribution available without kernel blobs by default since 2011. The Linux community uses the term "blob" to refer to all nonfree firmware in a kernel whereas OpenBSD uses the term to refer to device drivers. The FSF does not consider OpenBSD to be blob free under the Linux community's definition of blob. Selling software under any free-software licence

2080-539: Is now independently managed by the GNOME Project . GNU Enterprise ( GNUe ) was a meta-project started in 1996, and can be regarded as a sub-project of the GNU Project. GNUe's goal is to create free "enterprise-class data-aware applications" ( enterprise resource planners , etc.). GNUe is designed to collect Enterprise software for the GNU system in a single location (much like the GNOME project collects Desktop software),it

2160-415: Is permissible, as is commercial use. This is true for licenses with or without copyleft . Since free software may be freely redistributed, it is generally available at little or no fee. Free software business models are usually based on adding value such as customization, accompanying hardware, support, training, integration, or certification. Exceptions exist however, where the user is charged to obtain

2240-511: Is possible for a license to be free and not in the FSF list. The OSI list only lists licenses that have been submitted, considered and approved. All open-source licenses must meet the Open Source Definition in order to be officially recognized as open source software. Free software, on the other hand, is a more informal classification that does not rely on official recognition. Nevertheless, software licensed under licenses that do not meet

2320-490: Is released under a strong copyleft, although some is released under a weak copyleft or a lax, push-over free software license. The first goal of the GNU project was to create a whole free-software operating system. Because UNIX was already widespread and ran on more powerful machines, compared to contemporary CP/M or MS-DOS machines of time, it was decided it would be a Unix-like operating system. Richard Stallman later commented that he considered MS-DOS "a toy". By 1992,

2400-644: Is still maintained today and states that software is free software if people who receive a copy of the software have the following four freedoms. The numbering begins with zero, not only as a spoof on the common usage of zero-based numbering in programming languages, but also because "Freedom 0" was not initially included in the list, but later added first in the list as it was considered very important. Freedoms 1 and 3 require source code to be available because studying and modifying software without its source code can range from highly impractical to nearly impossible. Thus, free software means that computer users have

2480-598: Is summarized at the Debian web site. It is rare that a license announced as being in-compliance with the FSF guidelines does not also meet the Open Source Definition , although the reverse is not necessarily true (for example, the NASA Open Source Agreement is an OSI-approved license, but non-free according to FSF). There are different categories of free software. Proponents of permissive and copyleft licenses disagree on whether software freedom should be viewed as

2560-555: Is the same detailed history as at their web site. The GNU Manifesto was written by Richard Stallman to gain support and participation in the GNU Project. In the GNU Manifesto, Stallman listed four freedoms essential to software users: freedom to run a program for any purpose, freedom to study the mechanics of the program and modify it, freedom to redistribute copies, and freedom to improve and change modified versions for public use. To implement these freedoms, users needed full access to

Other influential examples include the Emacs text editor; the GIMP raster drawing and image editor; the X Window System graphical-display system; the LibreOffice office suite; and the TeX and LaTeX typesetting systems. From the 1950s up until the early 1970s, it was normal for computer users to have the software freedoms associated with free software, which

2800-468: The GNU General Public License . Combined with the operating system utilities already developed by the GNU project, it allowed for the first operating system that was free software, commonly known as Linux . The project's current work includes software development, awareness building, political campaigning, and sharing of new material. Richard Stallman announced his intent to start coding

Free software differs from: For software under the purview of copyright to be free, it must carry a software license whereby the author grants users the aforementioned rights. Software that

2960-741: The GNU operating system began in January 1984, and the Free Software Foundation (FSF) was founded in October 1985. He developed a free software definition and the concept of " copyleft ", designed to ensure software freedom for all. Some non-software industries are beginning to use techniques similar to those used in free software development for their research and development process; scientists, for example, are looking towards more open development processes, and hardware such as microchips are beginning to be developed with specifications released under copyleft licenses ( see

3040-667: The Linux kernel and other device drivers motivated some developers in Ireland to launch gNewSense , a Linux-based distribution with all the binary blobs removed. The project received support from the Free Software Foundation and stimulated the creation, headed by the Free Software Foundation Latin America , of the Linux-libre kernel. As of October 2012 , Trisquel is the most popular FSF endorsed Linux distribution ranked by Distrowatch (over 12 months). While Debian

In 1983, Richard Stallman , longtime member of the hacker community at the MIT Artificial Intelligence Laboratory , announced the GNU Project, saying that he had become frustrated with the effects of the change in culture of the computer industry and its users. Software development for

3200-449: The entire software of a computer grants its users all freedom rights (use, share, study, modify), even the most fundamental and important part, the operating system (including all its numerous utility programs) needed to be free software. Stallman decided to call this operating system GNU (a recursive acronym meaning " GNU's not Unix! "), basing its design on that of Unix , a proprietary operating system. According to its manifesto,

3280-469: The free software community . One of the most notable projects of the GNU Project is the GNU Compiler Collection , whose components have been adopted as the standard compiler system on many Unix-like systems. The copyright of most works by the GNU Project is owned by the Free Software Foundation. The GNOME desktop effort was launched by the GNU Project because another desktop system, KDE ,

3360-454: The kernel and the compiler were finished, GNU was able to be used for program development . The main goal was to create many other applications to be like the Unix system. GNU was able to run Unix programs but was not identical to it. GNU incorporated longer file names, file version numbers, and a crash-proof file system. The GNU Manifesto was written to gain support and participation from others for

3440-410: The source code was distributed to use these programs. Software was also shared and distributed as printed source code ( Type-in program ) in computer magazines (like Creative Computing , SoftSide , Compute! , Byte , etc.) and books, like the bestseller BASIC Computer Games . By the early 1970s, the picture changed: software costs were dramatically increasing, a growing software industry

3520-415: The source code . To ensure code remained free and provide it to the public, Stallman created the GNU General Public License (GPL), which allowed software and the future generations of code derived from it to remain free for public use. Although most of the GNU Project's output is technical in nature, it was launched as a social, ethical, and political initiative. As well as producing software and licenses,

3600-543: The Free Software Definition cannot rightly be considered free software. Apart from these two organizations, the Debian project is seen by some to provide useful advice on whether particular licenses comply with their Debian Free Software Guidelines . Debian does not publish a list of approved licenses, so its judgments have to be tracked by checking what software they have allowed into their software archives. That

The Fedora Project's distribution license guidelines were used as a basis for the FSDG. The Fedora Project's own guidelines, however, currently do not follow the FSDG, and thus the GNU Project does not consider Fedora to be

3760-423: The GNU Project has published a number of writings, the majority of which were authored by Richard Stallman. The GNU project uses software that is free for users to copy, edit, and distribute. It is free in the sense that users can change the software to fit individual needs. The way programmers obtain the free software depends on where they get it. The software could be provided to the programmer from friends or over

3840-470: The GNU Project in a Usenet message in September 1983. Despite never having used Unix prior, Stallman felt that it was the most appropriate system design to use as a basis for the GNU Project, as it was portable and "fairly clean". When the GNU project first started they had an Emacs text editor with Lisp for writing editor commands, a source level debugger , a yacc -compatible parser generator, and

3920-571: The GNU operating system began in January 1984, and the Free Software Foundation (FSF) was founded in October 1985. An article outlining the project and its goals was published in March 1985 titled the GNU Manifesto . The manifesto included significant explanation of the GNU philosophy, Free Software Definition and " copyleft " ideas. The Linux kernel , started by Linus Torvalds , was released as freely modifiable source code in 1991. The first licence

4000-452: The GNU project had completed all of the major operating system utilities, but had not completed their proposed operating system kernel , GNU Hurd . With the release of the Linux kernel , started independently by Linus Torvalds in 1991, and released under the GPLv2 with version 0.12 in 1992, for the first time it was possible to run an operating system composed completely of free software. Though

Copyleft is what helps maintain free use of this software among other programmers. Copyleft gives the legal right to everyone to use, edit, and redistribute programs or programs' code as long as the distribution terms do not change. As

The Free Software Directory maintains a large database of free-software packages. Some of the best-known examples include Linux-libre , Linux-based operating systems, the GNU Compiler Collection and C library ; the MySQL relational database;

4240-499: The Linux kernel is not part of the GNU project, it was developed using GCC and other GNU programming tools and was released as free software under the GNU General Public License . Most compilation of the Linux kernel is still done with GNU toolchains, but it is currently possible to use the Clang compiler and the LLVM toolchain for compilation. As of present, the GNU project has not released

4320-588: The code and find bugs and loopholes than a corporation would find practicable. According to Richard Stallman, user access to the source code makes deploying free software with undesirable hidden spyware functionality far more difficult than for proprietary software. Some quantitative studies have been done on the subject. In 2006, OpenBSD started the first campaign against the use of binary blobs in kernels . Blobs are usually freely distributable device drivers for hardware from vendors that do not reveal driver source code to users or developers. This restricts

4400-451: The combination of GNU and the Linux kernel "GNU/Linux", and asks others to do the same, resulting in the GNU/Linux naming controversy . Most Linux distros combine GNU packages with a Linux kernel which contains proprietary binary blobs . The GNU Free System Distribution Guidelines (GNU FSDG) is a system distribution commitment that explains how an installable system distribution (such as

4480-435: The developer) ultimate control over the software and, subsequently, over their devices. The right to study and modify a computer program entails that the source code —the preferred format for making changes—be made available to users of that program. While this is often called "access to source code" or "public availability", the Free Software Foundation (FSF) recommends against thinking in those terms, because it might give

4560-463: The founding goal of the project was to build a free operating system, and if possible, "everything useful that normally comes with a Unix system so that one could get along without any software that is not free." Development was initiated in January 1984. In 1991, the Linux kernel appeared, developed outside the GNU project by Linus Torvalds , and in December 1992 it was made available under version 2 of

4640-423: The freedom to cooperate with whom they choose, and to control the software they use. To summarize this into a remark distinguishing libre (freedom) software from gratis (zero price) software, the Free Software Foundation says: "Free software is a matter of liberty, not price. To understand the concept, you should think of 'free' as in ' free speech ', not as in 'free beer ' ". ( See Gratis versus libre . ) In

4720-412: The goals and messaging are quite dissimilar. According to the Free Software Foundation, "Open source" and its associated campaign mostly focus on the technicalities of the public development model and marketing free software to businesses, while taking the ethical issue of user rights very lightly or even antagonistically. Stallman has also stated that considering the practical advantages of free software

4800-409: The government charged that bundled software was anti-competitive . While some software might always be free, there would henceforth be a growing amount of software produced primarily for sale. In the 1970s and early 1980s, the software industry began using technical measures (such as only distributing binary copies of computer programs ) to prevent computer users from being able to study or adapt

4880-501: The impression that users have an obligation (as opposed to a right) to give non-users a copy of the program. Although the term "free software" had already been used loosely in the past and other permissive software like the Berkeley Software Distribution released in 1978 existed, Richard Stallman is credited with tying it to the sense under discussion and starting the free software movement in 1983, when he launched

4960-421: The late 1990s, other groups published their own definitions that describe an almost identical set of software. The most notable are Debian Free Software Guidelines published in 1997, and The Open Source Definition , published in 1998. The BSD -based operating systems, such as FreeBSD , OpenBSD , and NetBSD , do not have their own formal definitions of free software. Users of these systems generally find

5040-453: The lower initial capital investment and ability to freely customize the application packages. Most companies in the software business include free software in their commercial products if the licenses allow that. Free software is generally available at no cost and can result in permanently lower TCO ( total cost of ownership ) compared to proprietary software . With free software, businesses can fit software to their specific needs by changing

5120-487: The project. Programmers were encouraged to take part in any aspect of the project that interested them. People could donate funds, computer parts, or even their own time to write code and programs for the project.

(C-h g runs the Emacs editor command describe-gnu-project .) It

They generally advocate permissive free software licenses , which allow others to use the software as they wish, without being legally forced to provide the source code.

5440-435: The shift in climate surrounding the computer world and its users. In his initial declaration of the project and its purpose, he specifically cited as a motivation his opposition to being asked to agree to non-disclosure agreements and restrictive licenses which prohibited the free sharing of potentially profitable in-development software, a prohibition directly contrary to the traditional hacker ethic . Software development for

In 1983, Richard Stallman , one of the original authors of the popular Emacs program and a longtime member of the hacker community at the MIT Artificial Intelligence Laboratory , announced the GNU Project , the purpose of which was to produce a completely non-proprietary Unix-compatible operating system, saying that he had become frustrated with

5600-443: The software themselves or by hiring programmers to modify it for them. Free software often has no warranty, and more importantly, generally does not assign legal liability to anyone. However, warranties are permitted between any two parties upon the condition of the software and its usage. Such an agreement is made separately from the free software license. A report by Standish Group estimates that adoption of free software has caused

5680-411: The source and use the same license. This requirement does not extend to other software from the same developer. The claim of incompatibility between commercial companies and free software is also a misunderstanding. There are several large companies, e.g. Red Hat and IBM (IBM acquired RedHat in 2019), which do substantial commercial business in the development of free software. Free software played

5760-495: The users' freedom effectively to modify the software and distribute modified versions. Also, since the blobs are undocumented and may have bugs , they pose a security risk to any operating system whose kernel includes them. The proclaimed aim of the campaign against blobs is to collect hardware documentation that allows developers to write free software drivers for that hardware, ultimately enabling all free operating systems to become or remain blob-free. The issue of binary blobs in

5840-423: Was GNOME, which tackled the same issue from a different angle. It aimed to make a replacement for KDE that had no dependencies on proprietary software. The Harmony project did not make much progress, but GNOME developed very well. Eventually, the proprietary component that KDE depended on ( Qt ) was released as free software. GNOME has since dissociated itself from the GNU Project and the Free Software Foundation, and

5920-538: Was a proprietary software licence. However, with version 0.12 in February 1992, he relicensed the project under the GNU General Public License . Much like Unix, Torvalds' kernel attracted the attention of volunteer programmers. FreeBSD and NetBSD (both derived from 386BSD ) were released as free software when the USL v. BSDi lawsuit was settled out of court in 1993. OpenBSD forked from NetBSD in 1995. Also in 1995, The Apache HTTP Server , commonly referred to as Apache,

6000-511: Was becoming popular but required users to install Qt , which was then proprietary software . To prevent people from being tempted to install KDE and Qt, the GNU Project simultaneously launched two projects. One was the Harmony toolkit . This was an attempt to make a free software replacement for Qt. Had this project been successful, the perceived problem with the KDE would have been solved. The second project

6080-402: Was competing with the hardware manufacturer's bundled software products (free in that the cost was included in the hardware cost), leased machines required software support while providing no revenue for software, and some customers able to better meet their own needs did not want the costs of "free" software bundled with hardware product costs.

As of November 2014, the FreeRADIUS Project has three Core Team members: Alan DeKok (Project Leader), Arran Cudbard-Bell (Principal Architect), and Matthew Newton. The latest major release is FreeRADIUS 3. FreeRADIUS 3 includes support for RADIUS over TLS , including RadSec ,

6240-469: Was released under the Apache License 1.0 . All free-software licenses must grant users all the freedoms discussed above. However, unless the applications' licenses are compatible, combining programs by mixing source code or directly linking binaries is problematic, because of license technicalities . Programs indirectly connected together may avoid this problem. The majority of free software falls under

The economic viability of free software has been recognized by large corporations such as IBM , Red Hat , and Sun Microsystems . Many companies whose core business is not in the IT sector choose free software for their Internet information and sales sites, due to
