Free openwall gnu software for linux

Openwall GNU/*/Linux (or Owl for short) is a security-enhanced operating system with Linux and GNU software as its core, compatible with other major distributions of GNU/*/Linux. Openwall GNU/*/Linux is intended as a server platform. And, of course, it is free.
Main features:
- While we value quality above feature set, Owl does indeed offer a number of features besides just trying to be more secure.
- Most obviously, Owl can be used as a base for installing whatever software is generally available for GNU/*/Linux systems. It offers some compatibility (read below) for software packages found in or developed for other major Linux distributions, such as Red Hat Linux.
- Additionally, being a server platform, Owl will include a growing set of integrated Internet services.
- Owl includes a complete build environment capable to re-build the entire system from source with one simple command ("make buildworld"). (This is explained in more detail below.)
- Owl supports multiple architectures (currently x86, SPARC, and Alpha), as this lets you use it in more cases and helps us catch certain classes of software bugs earlier, thus improving the reliability of Owl packages.
Security:
- Owl combines several approaches to reduce the number and/or impact of flaws in its software components and impact of flaws in third-party software that one might install on the system.
- The primary approach used is proactive source code review for several classes of software vulnerabilities. However, because of the large amount of code, theres a certain level of "importance" for a software component or a part thereof to be audited. - Currently, only pieces of code which are typically run with privileges greater than those of a regular user and/or typically process data obtained over a network are audited before the corresponding software component is included. This covers relevant code paths in many of the system libraries, all SUID/ SGID programs, all daemons and network services. Other software may be audited when it is already a part of Owl. Potential problems found during the audit are fixed or, in some pathological cases, may prevent the software component from being included. In general, code quality and privilege management are always considered when theres a choice between implementations of a feature. As the project evolves, many of the software components will be replaced with ones of our own.
- When packaged for Owl, the software components are configured or, when necessary, modified in order to provide safe defaults, apply the least privilege principle, and introduce privilege separation. The use of safe defaults, where optional and potentially dangerous features need to be turned on explicitly, lets us audit the pieces of code used in in the default configuration in a more thorough way. Extra systems administration facilities ("owl-control") are provided for managing system features such as the optional SUID/SGID binaries independently from installing the corresponding packages. Every Owl package will have its audit status documented to allow for risk assessment.
- While source code review is the preferred way to deal with software vulnerabilities, it cant be applied in all cases. Typically, when insecure third-party software is installed on an otherwise secure system, "the game" is lost. The only thing an operating system can guarantee is that potential unauthorized access would be limited to those privileges granted to the software in question. However, in the recent years, a number of approaches were developed which reduce the likelihood and/or may reduce the impact of successful real-world attacks on insecure third-party software. Owl will use some of those "hardening" approaches in various parts of the system.
- Owl uses "strong" cryptography within its core components, and already includes some security policy enforcement (proactive password checking with "pam_passwdqc", password and account expiration, network address- based access control) and integrity checking ("mtree") capabilities. It is one of our goals to provide a wide range of security tools with Owl, available for use "out of the box".
Enhancements:
- After many Owl-current snapshots, Owl 2.0 release is finally out.
- Owl 2.0 is built around Linux kernel 2.4.32-ow1, glibc 2.3.6 (with our security enhancements), GCC 3.4.5, and recent versions of over 100 other packages.
- It offers binary- and package-level compatibility for most packages intended for Red Hat Enterprise Linux 4 (RHEL4) and Fedora Core 3 (FC3), as well as for many FC4 packages.
- Additionally, Owl 2.0 uses our new installer, making installation a lot easier than it used to be for Owl 1.1 and below.

Bluewall is a GNU/Linux distribution based on Debian and pkgsrc.
Bluewall GNU/Linux aims to create a complete pkgsrc-based GNU/Linux distribution.
Packages:
- debian
- pkgsrc
- pkgsrc(cd-rom)
Enhancements:
- After some long time, a new bluewall has been released.
- This is a transient release, after the maintainer change this version tries to be a testing release, but feel free to report bugs!
- This new version updates the base debian to SID aka Debian unstable, also integrates the current CVS tree and some (541) i386-binary pkgsrc packages like Gnome, 2.12.2, Gimp 2.2.10, Xorg 6.8.1...

Pingwinek is a GNU/Linux and GNU/Haiku distribution made in Poland. The main desktop a for GNU/Linux is GNOME. The distro supports Polish and English languages and can also be run as a Live CD.

Pingwinek is an independent distribution. This means that it doesnt synchronize with changes made by other Linux distributions and it uses own package management system called box.

This Live edition could be installed on hard disk (copied). The whole distribution contains over 1300 packages and in 1.0 release is only served as preinstalled system. This means that you cannot select packages to install. Release 2.0 would have installer with an option to choose and install packages via FTP server.

Live GNU/Linux the free Knoppix as it takes the usual Knoppix from Klaus Knopper, and strips off all non-free bits and bytes. The result is a product that consists entirely of Free Software.

We hope to provide a useful Free Software resource for you. Live GNU/Linux is also meant as a live system others can base customised version on, if they want to build up a Free Software system as well.

Live GNU/Linux is based on Knoppix which itself is based on Debian GNU/Linux. Freeing the original Knoppix was developed at Intevation.

Conjury::C::GNU is a Perl Conjury with the GNU C/C++ tools.

SYNOPSIS

c_compiler Vendor => GNU,
Language => I ,
No_Scanner => 1,
Program => I ,
Options => [ I , I , ... ],
Journal => I ;

c_linker Vendor => GNU,
Language => I ,
Program => I ,
Options => [ I , I , ... ],
Journal => I ;

The optional Program, Options and Journal arguments to the GNU-specific specializations of the c_compiler and c_linker functions are simply passed through unmodified to the base class constructor.

The optional Language argument specifies the langauge for which the compiler or linker should be invoked. The C language is the default if not otherwise specified. The value is case-insensitive and may be any one of the following: c, c++ or objective-c.

The optional No_Scanner argument in the c_compiler specialization specifies that the processing overhead of scanning all the source files for their dependency trees is unnecessary. If you are only building from clean source file hierarchies (with no existing products from previous runs), then the construction time of large builds may be improved with this option.

The Debian GNU/kFreeBSD ISO image contains a basic rescue system with GNU/kFreeBSD.
Its usable for simple tasks or for just testing, but doesnt setup writable filesystems, nor have the development tools installed.
Debian GNU/kFreeBSD can also be used to install Debian GNU/kFreeBSD.
Enhancements:
- An installer based on the FreeBSD 6.2 kernel was added.

Barefoot GNU/Linux is a linux distribution based on Vector Linux and Slackware.

- Support for sinhala (sinhala-gtk-im, scim, unicode and non-unicode fonts)
- Based on Vector Linux & Slackware
Version restrictions:
- upon first boot X will crash - login as root & init 4; or reboot to reslove this
- lilo might have issues
- the documentation and installer are vectorlinuxs we need to hack these (installer is under heavy modification...)

GNU Go is a free program that plays the game of Go. GNU Go has played thousands of games on the NNGS Go server.

GNU Go is now also playing regularly on the Legend Go Server in Taiwan, on the WING server in Japan, and many volunteers run GNU Go clients on KGS. GNU Go has established itself as the leading non-commercial go program in the recent tournaments that it has taken part in.
