Le système d'exploitation universel Explaining BSD Last modified on 2018-06-29 07:33:14 by eadler. Abstract In the open source world, the word “Linux” is almost synonymous with “Operating System”, but it is not the only open source UNIX® operating system. So what is the secret? Why is BSD not better known? This white paper addresses these and other questions. Throughout this paper, differences between BSD and Linux will be noted like this. BSD stands for “Berkeley Software Distribution”. The BSD kernel, which handles process scheduling, memory management, symmetric multi-processing (SMP), device drivers, etc.The C library, the base API for the system.The BSD C library is based on code from Berkeley, not the GNU project.Utilities such as shells, file utilities, compilers and linkers.Some of the utilities are derived from the GNU project, others are not.The X Window system, which handles graphical display.The X Window system used in most versions of BSD is maintained by the X.Org project.
m0n0wall m0n0wall is a project aimed at creating a complete, embedded firewall software package that, when used together with an embedded PC, provides all the important features of commercial firewall boxes (including ease of use) at a fraction of the price (free software). m0n0wall is based on a bare-bones version of FreeBSD, along with a web server, PHP and a few other utilities. The entire system configuration is stored in one single XML text file to keep things transparent. m0n0wall is probably the first UNIX system that has its boot-time configuration done with PHP, rather than the usual shell scripts, and that has the entire system configuration stored in XML format. Announcement regarding the freeze of the mailing list and forum, with some pointers on where to go for m0n0wall successors. After 12 years, the m0n0wall project has officially ended. No development will be done anymore, and there will be no further releases.
DragonFly BSD Le système d'exploitation universel Télécharger Debian 9.3(installation par le réseau pour PC 64 bits) Debian est un système d'exploitation libre pour votre ordinateur. Un système d'exploitation est une suite de programmes de base et d’utilitaires permettant à un ordinateur de fonctionner. Debian est bien plus qu'un simple système d'exploitation : il est fourni avec plus de 51000 paquets . Ce sont des composants logiciels précompilés, assemblés dans un format ingénieux conçu pour une installation aisée sur une machine. Lire la suite… La dernière version stable de Debian est la 9.3. Pour commencer Si vous souhaitez commencer à utiliser Debian, vous pouvez facilement en obtenir une copie, et ensuite suivre les instructions d'installation.

Console Server Last modified on 2014-04-28 by wblock. Abstract This document describes how you can use FreeBSD to set up a “console server”. You have a computer room with lots of UNIX® server machines and lots of communications hardware. You need access to the console because when things break, that is where error messages go. If we are going to play about with consoles, then there are a couple of other things that would be great: Remote access.
Dragonfly BSD A technical introduction: The ultimate goal of the DragonFly project at its inception was to provide native clustering support in the kernel. This type of functionality requires a sophisticated cache management framework for filesystem namespaces, file spaces and VM spaces. These and other features eventually culminate in the ability to allow heavily interactive programs to run across multiple machines with cache coherency fully guaranteed in all respects. This also requires being able to divide resources, including the cpu by way of a controlled VM context, for safe assignment to potentially unsecured third-party clusters over the internet. DragonFly has been going through rapid and ever increasing development since the fork in 2003. In the 2007-2008 time-frame a new filesystem called HAMMER was developed for DragonFly. Recently, many developers have focused on SMP scalability while others have put an emphasis on new feature development and driver porting.
Linux kernel The Linux kernel is released under the GNU General Public License version 2 (GPLv2) (plus some firmware images with various non-free licenses), and is developed by contributors worldwide. Day-to-day development discussions take place on the Linux kernel mailing list. The Linux kernel was initially conceived and created in 1991 by Finnish computer science student Linus Torvalds. Linux rapidly accumulated developers and users who adapted code from other free software projects for use with the new operating system. The Linux kernel has received contributions from thousands of programmers. History In April 1991, Linus Torvalds, a 21-year-old student at the University of Helsinki, Finland started working on some simple ideas for an operating system. After that, many people contributed code to the project. By September 1991, Linux version 0.01 was released on the FTP server (ftp.funet.fi) of the Finnish University and Research Network (FUNET).
