OpenBSD

OpenBSD is a free access, NetBSD derivatives from BSD operating system. Project leader in 1995 Raadt Theo DE launched OpenBSD project, hoping to create a notice safety of the operating system.

introduction

From NetBSD OpenBSD is a derivation of class Unix operating system. Project leader and uefa dryden, Theo De if Raadt) (launched in 1995 OpenBSD project, hoping to create a notice safety operating system, in addition to high product OpenBSD also

Qualitative documents, adhere to the open code and strict software license is famous. OpenBSD is the mascot of thorn dolphin. OpenBSD contains some lack in other operating system or selectively security functions, moreover OpenBSD extreme value code quality, any of the core modifications are need to pass strict censorship. In 17 different OpenBSD can operate under the environment of the hardware, including the Intel i386 gamerelease, DEC Hewlett Packard PA - -, Motorola 68000 RISC, AMD64, PowerPC, from SPARC etc,.

Development history

In December 1994, the common sponsors NetBSD Theo Raadt were asked to resign coque NetBSD development work, and his NetBSD code access rights are being cancelled. Theo Raadt DE the actual for reasons unknown resignation, although he claimed that NetBSD development team because and conflict and quit development work. Many people think that Raadt Theo DE left because of personality difficult, but there are also many people think he is a straightforward person, and leave because some people don't agree with him extreme attention to operating system security concept.

In October 1995, Raadt Theo DE NetBSD 1.0 derived from the OpenBSD plan, in July 1996 to release the initial release OpenBSD 1.2, October release the OpenBSD 2.0. Every 6 months after OpenBSD will release a new version, each released the maintenance 1 year.

July 25, 2007, OpenBSD decided to set up a OpenBSD foundation. The nonprofit foundation will provide OpenBSD users or the organization to legal support services OpenBSD, organization located in Canada.

Open source

When founded, Theo DE OpenBSD Raadt decided to anyone can get original code at any time in Chuck Cranor, with the help of he established a publicly and anonymous CVS server, was the first to open CVS as development way software. Because the time only mostly in application CVS to a few developers have access rights, external developers have no way to know the current schedule, contributions and often is modified files the correction has been completed. This development way to become open source code OpenBSD representatives of software.

System security

Until June 2002, the web site before OpenBSD is such a statement:

"In default installation, for the past six years without any distal loophole was found"

In June 2002, Mark OpenSSH Dowd found under one of the default installation distal loophole, therefore website statement into:

"In default installation, more than 8 years time only a remote loophole was found" "

On March 13, 2007, by finding a OpenBSD and distal loophole, therefore website statement and change:

"In default installation, more than a decade of time only two distal loophole was found"

But the statement was also criticized for OpenBSD, under the preset installation services, rarely running system, and is usually installed service, the more chance to happen. The loophole This statement a little OpenBSD doesn't accord with the actual situation, but OpenBSD is still quite safe operating system.
