WHAT IS OPEN BSD?
• OpenBSD is a Unix-like computer operating system descended
from Berkeley Software Distribution (BSD), a Unix derivative
developed at the University of California, Berkeley.
• It was forked from NetBSD by project leader Theo de Raadt in late
1995, coordinated his home in Calgary, Alberta, Canada.
•Produced portable versions of numerous subsystems, most
notably PF, OpenSSH and OpenNTPD, which are very widely
available as packages in other operating systems.
•Emphasizes portability, standardization, correctness, proactive
security and integrated cryptography.
• Developed entirely by volunteers. The project's development
environment and developer events are funded through
contributions collected by The OpenBSD Foundation.
• This project produces a free, multi-platform 4.4BSD-based UNIX-like
• Freely available from our FTP/HTTP sites or a 3-CDs set.
• The current release is OpenBSD 5.4 which was released Nov 1,
• Its website is www.openbsd.org.

OPENBSD RUNS ON FOLLOWING
• Alpha (Digital Alpha-based System)
• amd64 (AMD64-based System)
• armv7 (ARM based appliances)
• hp300 (Hewlett-Packard HP9000 series 300 and 400
• hppa (Hewlett Packard Percision Architect System)
Its logo and mascot is a pufferfish named Puffy.
• In December 1994, NetBSD co-founder Theo de Raadt was asked to
resign from his position as a senior developer and member of the
NetBSD core team.
• In October 1995, de Raadt founded OpenBSD, a new project forked
from NetBSD 1.0. The initial release.
• OpenBSD 1.2, was made in July 1996, followed in October of the same
year by OpenBSD 2.0. Since then, the project has followed a schedule
of a release every six months, each of which is maintained and
supported for one year.
• In September 2005, the nascent BSD Certification Group performed a
usage survey which revealed that 32.8% of BSD users (1420 of 4330
respondents) were using OpenBSD, placing it second of the four major
BSD variants, behind FreeBSD with 77% and ahead of NetBSD with 16.3%
• On 25 July 2007, OpenBSD developer Bob Beck
announced the formation of the OpenBSD Foundation, a
Canadian not-for-profit corporation formed to "act as a
single point of contact for persons and organizations
requiring a legal entity to deal with when they wish to
• The latest release, OpenBSD 5.4, appeared on 1 Nov 2013.
OpenBSD 5.4 - running Firefox on the default window manager
• OpenBSD includes a number of security features in which
developers audit the source code for software bugs and
• As with most other BSD-based operating systems, the
OpenBSD kernel and userland programs, and common tools
like cat and ps, are developed together in one source code
• The OpenBSD project maintains ports for 20 different hardware
OpenBSD's security enhancements, built-in
cryptography and the pf packet filter suit it for use in the
security industry, for example on firewalls, intrusion-
detection systems and VPN gateways.
OpenBSD ships with the X window system and is
suitable for use on the desktop.
Packages for popular desktop tools are available,
including desktop environments GNOME, KDE, and Xfce;
web browsers Konqueror, Mozilla Firefox and Chromium;
and multimedia programs MPlayer, VLC media player
OpenBSD features a full server suite and is easily
configured as a mail server, web server, ftp server, DNS
server, router, firewall, or NFS file server.

not an official OpenBSD release in the sense which this term
subsequently came to be used in.
1.2: July 1, 1996

• It lacks the support for devices that Linux has. The wealth of
software available for it isn't as large as Linux, though
many Linux applications will work in *BSD out of the box.
• It isn't as newbie-friendly as other operating systems, such as
Windows, OS X, or Linux distros such as Ubuntu.
• OpenBSD has virtual firewalls. Using this is like accepting the
risk of using virtual machine. In this case if your virtual machine
system is not stronger than OpenBSD, we should not use it. If
one can exploit virtual machine he/she can hurt your
