The difference between FreeBSD, OpenBSD, NetBSD's
Linux's history
http://www.361way.com/unix-bsd/1513.html
Unix has been in my mind status are high, unix stability and integrity of the windows and linux is unmatched. And from another sense, linux actually be a branch from unix inside. I have only the program will be installed only in honor of AIX installed, but at the time of unix / linux system knows even less. To hardware limitations induced by the environment, so that the reuse missed. The HP-unix, too, are only on their own cpu hardware support. And the civilians in the unix more famous when the number of the BSD family. Even fame Apple is evolving from this branch inside out.
BSD family, well-known and the number of FreeBSD, OpenBSD, NetBSD, What is the difference between the specific and the three links, the following look from "home owners" a good comparative evaluation:
Forget Windows and Linux it, is perhaps less well-known BSD you need.
If the mentioned Web or reading a computer magazine it is impossible not related to Linux, it is by Linus Torvalds and others to develop a great operating system. But while Linux occupy the most important position, ISP and system administrators often choose BSD as the operating system in one, is a kind of built on BSD code-sharing on the basis of the operating system in the past 20 years, the United States the top schools have been studying it.
What BSD what is it? If you are looking for a non-Windows operating system, and why you should consider using them? Academic Origin Berkeley Software Distribution BSD is the abbreviation, which is a collection of software developed by the University of California, Berkeley. Initially only as add-on packages BSD Unix earlier versions of AT & T appears, then gradually developed into a complete, highly complex operating system with Unix-style - it is the first integrated network functionality.
Efforts by academic institutions pursuing perfectionism and picky after generations of students tested, BSD is perhaps the most robust, safest and most reliable operating system. For the BSD-based operating systems run a few years without maintenance or restart is a very normal thing. Because BSD is developed under the code open environment, it therefore all customers (including those software developers that want to implant a commercial product) is completely free of charge. BSD network code from the central part of almost all modern operating systems, including 95 since almost every version of Linux, OS / 2 and Windows Windows.
Secret Weapon
If BSD is really so good, why they do not like it to become the market leader like Linux? This is one of the most important reason is cultural. Many Linux software developers to see themselves as revolutionaries. But the academic community (BSD real roots of the place) members are more focused on results rather than the well-known products. BSD system administrators and ISP user also has a group of loyal followers, but these people generally prefer BSD as their secret weapon, rather than spread everywhere they are using this operating system.
As a result, not many people realize that the various versions of BSD-based or as large as the Yahoo! site, but also on IBM InterJet and Maxtor network storage server these highly reliable embedded systems provide a favorable support. BSD is a variant of NetBSD is considered to be the world's most portable operating system that can run on different CPU (over 64 species) and hundreds of different brands and models of computers.
Now, there are five popular BSD operating system, one of the three --FreeBSD, NetBSD and BSD OpenBSD-- has been authorized, the operating system and source code is free, anyone can be used for any purpose. The remaining two BSD / OS and Mac OS X are commercial products, they are open BSD code base, it has a special and unique technical advantages. In this article, we will discuss the free version. As for the discussion of BSD / OS and Mac OS X as well as the establishment of the Linux General Public License BSD license on the basis of the advantages, see the other articles on our site "More about BSD".
BSD family of Grand --1.FreeBSD
FreeBSD is developed from the ground up on 386BSD, while 386BSD is a computer scientist Bill Jolitz Berkeley BSD development of a version for the Intel 80386 chip. For this reason, FreeBSD always work best on x86 machines 32-bit system. The number in the free BSD, with its best and PC compatible, and supports PC-compatible external devices is also up. While FreeBSD can also run on the Alpha processor, also be transplanted to other architectures them, but you should see it as the main operating system for x86 systems.
In the free BSD, FreeBSD is the biggest reputation, it has the most powerful development team, also received the most feedback letters, also has the largest number of users. It may be all free operating system is the most easy to install - especially if you want over the Internet instead of buying a CD, then install it.
Linux distributors often made difficult by their copy of Internet installation. After all, their business depends on the sales of the disc. And FreeBSD is not the case: it's all requirement is two floppy disks (it is easy to create tools and mapping files on the FreeBSD Web site) and the appropriate speed internet access. Started from the first floppy disk, and then insert the second. The installer will help you choose configuration options, download the entire system from the Internet and put everything correctly installed. Those who want the disc can be obtained from the FreeBSD Mall where Wind River Systems, or from Cheap Bytes there. You can also make a CD ISO with a mapping file on FreeBSD Web site.
FreeBSD Another powerful is that it has a wide range of application software support - more than 5800 kinds of free programs are available for you to download and immediately added to the FreeBSD system. In fact, all you need to build a business workstation or a server with FreeBSD software has been installed on their own or can be subsequently added to the system.
In addition, like NetBSD and OpenBSD, like, FreeBSD actually be able to run all programs for Linux, SCO Unix or Intel version of Solaris. As with Linux, FreeBSD, and all using the X Window System developed for the desktop and graphical user interface protocols, including KDE, GNOME and procedures both wrote.
Finally, FreeBSD has the most references for new users. FreeBSD Handbook provides excellent instructions for the new customers. Many publishing companies have launched a guide book for beginning and advanced users written.
In short, FreeBSD for Linux is a powerful challenger, it may be able to provide superior stability, simplicity, and ease of installation.
BSD family of Grand --2.OpenBSD
OpenBSD is another of the free BSD derivatives, known as the world's most secure operating system. OpenBSD's home page (www. Openbsd.org) reported that OpenBSD "in the default installation without a small security hole within four years," it means that (in fact, no one knows) OpenBSD version released in the past four years none of the attacks was broken from the Internet. (Of course, you can also make any operating system - including OpenBSD-- become vulnerable if you do not properly configure the server or run that led intruders insecure software.) OpenBSD is also fully integrated with password security software ensure data security.
OpenBSD is not the most integrated functions on behalf of Unix components, it is not the fastest run. But in these areas, it is not too bad. The operating system is very small, but very efficient, it can on old 486 machines only 16MB of memory to run very well - you know such a hardware configuration is not running Windows 2000. Other operating systems do not have any record of high reliability with views of OpenBSD on security issues created. Some remote root of the problem usually occurs every month on the Microsoft operating system, such as Windows 2000. Many recently released Linux Ramen worm has become a class of viruses target.
Like like FreeBSD and NetBSD, OpenBSD, there are many application software support, which includes many customized versions of free software packages. It's no software library in FreeBSD's so big, but contains most of the tools you want to install a Unix server or workstation. OpenBSD is also capable of running the x86 version of the program for FreeBSD, Linux and Solaris created. OpenBSD supports 10 computer architecture - has more than FreeBSD, NetBSD, but no more. Cheap Bytes OpenBSD itself or from where you can get OpenBSD CD. However, you do not get the ISO-mapped files, because the development group are more willing to sell by way of the CD as a support for their efforts. You can install the operating system over the network, but the installer's user interface is not FreeBSD so beautiful it. In the three free BSD, OpenBSD and least developed members of the novice Unix
is the most difficult to learn. But if you really need a robust network firewall or server, then, OpenBSD is the right choice.
BSD family of Grand --3. NetBSD
NetBSD
NetBSD is free as BSD, which is based on BSD's most portable operating system. Currently able to run (they are trying to make it more able to adapt to the framework), x86-64 Hammer from the original structure based Macintosh 68K or Amiga until AMD has not released, NetBSD on 46 different hardware architecture as much They are able to run well.
This portability makes the best choice for an embedded system NetBSD (in other devices operating in the invisible computer). Since writing the most likely to expose flaws in the code from one platform to another platform (otherwise it will not be noticeable), and the code from NetBSD but it is rare robust; OpenBSD (originally designed for NetBSD objects) and FreeBSD in the past have had it for reference. NetBSD is a lot of choice of operating system independent of the type of hardware, including the old Sun workstation.
Like, like FreeBSD and OpenBSD, NetBSD has a huge library of applications (less than FreeBSD and OpenBSD multi-ratio), and the ability to run Linux and other versions of Unix for commercial building program. From Wasabi Systems, Cheap Bytes and other NetBSD Web site lists resources to where we can get NetBSD CD. You can download the ISO CD-mapped files, it can also be installed via FTP.
After reading the comments "on the home station", individuals also want long-winded a few words:
If the server production environment to use, personally I recommend using FreeBSD. In addition FreeBSD has three more famous branch, felt the need to introduce:
-
FreeNAS is an open source storage platform based on FreeBSD and supports sharing across Windows, Apple, and UNIX-like systems.
-
PC-BSD is a FreeBSD derivative with a graphical installer and impressive desktop tools aimed at ease of use for the casual computer user.
-
pfSense is a free, open source customized distribution of FreeBSD tailored for use as a firewall and router.
These are freeBSD from the official website of the three.
-
The case is due to security considerations, openbsd is a good choice. But openbsd support package is relatively small, it is more suitable for use as a firewall.
-
NetBSD is the largest hardware support. Some of the more so when the older hardware can not turn supported by a drive system, old material can be utilized, hold NetBSD.
