From the foregoing it is clear that Microsoft, too, used or "stolen" code, not just Linux. BSD grew in the 1970s with the Defense Advanced Research Projects Agency (DARPA) support. Version 4.3 BSD (1986), 4.3 BSD Tahoe (1988), Net BSD 1 (1989), and so on followed. The story is also well described on BSD sites, such as www.freebsd.org. FreeBSD, for example, began as a project in 1993, shortly after NetBSD and OpenBSD is a fork of NetBSD, but they are all from 386/BSD.

Prebuilt packages, too, can be installed with a snap. Unlike RPM archives, which you must install the dependency in consecutive order, here you have everything on tap. And with the "pkg_add ftp://ftp.openbsd.org/pub/OpenBSD/4.0/packages/i386/package.tgz-v" command that you still download the Internet without specifying a set of the version. It is something that most packagers Linux can not do, only APT (Debian) and its clones.

The widespread use of Linux helped some users to move to BSD for good, that different opinions made the issue of "Linux-against-BSD" visible to the public, which makes the BSD world seems more attractive.

Why OpenBSD or BSD?

OpenBSD can run on a Linux binary emulation layer; DOS (and other) within the emulator Qemu, as well as FreeBSD and other BSD Unix and binaries. OpenOffice.org but has not yet been (do you really need a large mass of software when there are more solutions at hand?), You can easily write or open your documents in MS Word TextMaker for Linux, or in the port OpenBSD AbiWord.

There are many reasons why the BSD systems are less noticeable. The availability of Live CD's and easy to use presentation is something that in BSD systems delayed. May you download Linux ISO images at the drop of a hat. With BSD systems, is a bit different. You could hardly find a desired BSD Live CD in the 1990s. Only a few of them seem now.

Most users who use Linux use it because they hate Microsoft, the people who use BSD because they like to use Unix

OpenBSD 4.0 is suitable for most networks or clerical duties. After downloading a fine MP3 players, I was able to instantly listen to music. The X Window look no different from any Unix box. VLC or MPlayer multimedia players will help you enjoy your favorite music recordings or films.

It would be a good idea to make the DVD bootable OpenBSD with packages that are included – just download and put them in a directory (for example, a directory of "packages") where you have your database files OpenBSD installation, then apply the mkisofs command above.

If you see the euphoria of KDE or Gnome Desktop and other applications running smoothly, May you soon disappointed – OpenBSD fewer packages Linux or FreeBSD. For example, running VMware on FreeBSD has been possible for quite a long period; OpenBSD (OpenBSD, but not in the VMware environment) requires some smart adjustments to achieve this goal.

Linux is more developed in terms of accessibility to various types of equipment such as inkjet printers Wi-Fi or USB solutions. But that is because, as I said earlier, various support. Linux is good for desktop users who want to forget Microsoft and BSD systems are better as a server / router / firewall solutions. Many good administrators say that Linux behaves much worse as a server that BSD systems. Something like Red Hat or SuSE Enterprise Server is not a joke – these systems cost much money. Any good administrator can bet on BSD or other Internet solutions today. Slackware Linux is exception – it is one of the best.

Linux against BSD

Many "great" companies that sell their products safety incredible "forget that using carrier pigeons of the communication is by far a more stable than any computer communication – an encrypted e – mail, if you are already under suspicion, always get intercepted, and governments still have enough resources and money to do their job well.

OpenBSD could be from a Linux user's point of view, a Pandora's box. Some May Disagree with me, but in the world where all major operating systems placed on the ease of use graphical interface and interactivity, it is certainly the case. This means that you must forget the graphical installer – your first contact with the system is the text mode. But the text is the best format for some people like.

The BSD family of operating systems consists of a base system and packages. The OpenBSD kernel – its kernel and base system (system / network utilities, man pages, etc.) get with caution, not paranoically checked for security holes.

OpenBSD in action

Many companies want to get the highest profit and they introduce various technologies that serve as competition marketing strategy for most of the time and are often unnecessary. Bluetooth or WiFi technology in your mobile phone provides a safety risk at any good hacker can access your most sensitive data in seconds from your neighborhood. Most users do not have time to study the various safety data sheets and they often live happy without knowing they are not protected. I am not saying that new technologies are still absurd, but they deserve praise relevant only if it is used in the right place.

The following files contain the OpenBSD installation – networking, Unix commands, X Window, manual pages, not like KDE, Aspell, etc. Overview of BSD systems with emphasis on OpenBSD

It is important to say that the ISO file can not be burned onto a CD as a single file as an MP3 file – it can be done that way, however, but you will not be able to boot from a CD / DVD. If you use Windows, common sense for burning ISO files is to use the "burn image" in programs like Nero Burning ROM (or "burn ISO" in other software). Under FreeBSD, you can burn the ISO image with the burncd command (if your CDROM is the master on the second IDE channel, "-s" is for speed):

When not in the future, you're ready to download a newer version of OpenBSD with the purpose to make a bootable CD / DVD, simply changing the cdrom40.fs "in the above mkisofs (4.0 is the current version of OpenBSD) to the version it agrees with, for example, "cdrom45.fs" (a future OpenBSD), which is a bootable image that the emulation of large disk. A CD or DVD burned with this ISO file will start on any PC (no DVD UDF, but DVD format ISO).

Have you lost somewhere in the text mode console? Use the F5 key (Ctrl + Alt + F5) to return to X Window. Are you a beginner? Type "afterboot man." Are you used to Linux and you prefer a Linux terminal type? After each logon, OpenBSD asks you to enter the terminal type you want, but the default – vt220 – the card key as you used to Linux if you use programs like Midnight Commander (by example, like F7 to F6, Etc, but not in X). After typing "nxterm" everything should work OK.

The system and packages

If a reader understands, the world's major policy is to create a matrix or a large network of dependencies – if the vehicle can run on Linux, Linux users (and possibly buy Red Hat or Xandros).

Linux Linux is based on a Unix clone (Minix), which was far in functionality compared to Unix over time. Terminology speaking, Linux is only the kernel.

Installation is very easy. For beginners, it is recommended to use a mobile rack and use the old disk (about 3 gigabytes). The reason is that the installation of OpenBSD already partitioned a disk requires a lot of knowledge and if users do not want to worry about the number of sectors / cylinders and other things, they must type the text of assistant This solution is very practical.

Usability

Another aspect that makes the world of Linux and BSD systems different is that the BSD OS have everything under a cover and control. Linux is dark waters because it is not united. For example, you have a DEB (Debian Linux) together – you will not always install if you use Mandrake and SuSE. A long list of problems arising from differences between Linux distributions May be written. Linux users probably remember the UnitedLinux effort, but now it is devoid of life. In the chaos where it installs a Linux system with various services and the other does not, we see that the Linux community is that all broken.

OpenBSD

BSD systems work well with all types of standard equipment, but some users say they are "less easy to use." On the other hand, others consider the so-called "friendly" to be an obstacle to the necessary configurations . In other systems, where many services run automatically, it is a bit irritating when administrators at their own security policies in mind, must disable on a regular basis after each installation.

The Linux-BSD-against "the discussion is very sensitive for some people – May they get very angry about any direction, either in favor of Linux or BSD. This is not a good idea to compare these systems throughout, but this is not a bad idea to compare their "friendly" in different aspects, such as a "desktop solution", "solution Office "," multimedia solution "," server solution "," firewall solution ", etc.

The system starts up quickly (much faster than Linux). If you selected the X Window environment during the installation wizard text, you simply launch the "xorgcfg" command from the console to configure your X Window environment.

The organizer has a different philosophy of packaging compared to Linux. It uses ports and packages. The ports are the fingerprints of applications on your disk. They contain the basic information they can be downloaded from. You just "cd" somewhere in the hierarchy of the directory / usr / share / ports directory, where applications are divided into categories, then type "make install" and wait for sources to download, compiled and installed.

I raised the problem of building such a CD myself. I worked hard with FreeBSD. I managed. Later, I focused on OpenBSD, as it has a good reputation for its strong security structure. I managed too. But this would require more writing and this article does not make OpenBSD Live CD, I just want to develop this system and give some advice to make a simple installation boot OpenBSD CD / DVD, which is also difficult to obtain.

Installation

History

The policy of the OpenBSD team is to sell CDs. Unless you're ready for a difficult installation of the network, you have two options: either you buy their CD, or build them yourself. If you choose this option, download the basic system of mirrors FTP: www.openbsd.org / ftp.html. Choose as your AMD64 architecture or i386 and the version (like 4.0, 3.9, etc.). Place all downloaded files in a directory (eg / usr / opbsd) and the following command to make the image of the ISO following:

If we are talking in general we can say that "BSD is much more stable, as it is a real Unix" and that "Linux is a very good toy office more responsive to the needs of users, as the has done more drivers and applications ".

OpenBSD 4.0 packages system – #, you can create this directory and put the package in this cksum, INSTALL.i386, INSTALL.Linux, MD5, base40.tgz, BSD, bsd.mp, bsd.rd, cd40.iso, cdboot, cdbr, cdemu40.iso, cdrom40.fs, comp40.tgz, etc40.tgz, floppy40.fs, floppyB40.fs, floppyC40.fs, game40.tgz, index.txt, man40.tgz, misc40.tgz, pxeboot, xbase40. tgz, xetc40.tgz, xfont40.tgz, xserv40.tgz, xshare40.tgz

To put it metaphorically, the Internet emerged BSD. This is not because these systems can process the largest traffic servers, but because the concept of IP addresses and TCP / IP BSD is an invention. If you right-click on the file "winsock.dll" in Windows 98 (C: Windowswinsock.dll), you will see "BSD Windows Socket API" in the Properties> Version window, but "BSD" is not seen in more recent Windows systems "version information" window Winsock.dll. But there are many writings on the Internet about this if you Google the two words: "winsock.dll" AND "bsd". BSD systems have a different policy license and anyone can take their code. BSD license gives more freedom for programmers.

BSD: BSD systems are based on an actual Unix variant called Berkeley Software Distribution, which has a long history.

New technology and automation can also impose a risk

The power of a good policy that you feel somewhat immune to bad behavior of the world, because you do not have to fear that network services, for example, contain security vulnerabilities. Something like that happens often with Linux – web sites ask users to download important fixes shortly after distributions are released. With this particular security OpenBSD as a BSD system is outside the usual crowd.

Today, when too many companies to highlight different distributions, it is difficult to say which of them best meets our needs and May you be mixed in such a list. If companies are investing money to a software solution, they become disappointed in May when its license policy changes. OpenBSD has a robust feature above all – the system and packages are fully audited for security holes.

I was a BSD user since the late 1990s. I started with FreeBSD 3.0 and I also made my own distribution FreeBSD – a small disk entitled 1fcdbsd, which boots any x86 computer and plays MP3 files from a hard drive or CD's (disk audio CD and MP3 Player – http:// www.freebsd.nfo.sk/). I gained some experience with the BSD, which develops rather on the side without the knowledge that it is almost the best.

mkisofs-bc-cdrom40.fs boot.cat RVO / usr / my_openbsd.iso / usr / opbsd

The above command May be used both Linux and BSD systems in and, possibly, in any system that is held mkisofs.

A manual text mode configuration is an absolute preference here. Almost all services are turned off – a first choice for any good administrator, as he has ultimate control over the entire system. Users, too, may become familiar with Unix and see what happens under its hood. To run X Window, simply run the "startx" command. If you want to change or re-edit the configuration files, make your choice in the directory / etc with vi as your editor. Do you want to add more packages? Just download and issuing "pkg_add-i package.tgz command" and that's all!
