OpenBSD 6.0 - CD

Version 6.0 Release Date: September 1, 2016 - Changelog

NOTE: This distro comes on 2 CDs. You will receive both 32 bit and 64 bit versions. Please ensure that your system will read from a CD before ordering.

The OpenBSD project produces a freely available, multi-platform 4.4BSD-based UNIX-like operating system. Our goals place emphasis on correctness, security, standardization, and portability.

Why might I want to use OpenBSD?

New users frequently want to know whether OpenBSD is superior to some other free UNIX-like operating system. That question is largely unanswerable and is the subject of countless (and useless) religious debates. Do not, under any circumstances, ask such a question on an OpenBSD mailing list.

Below are some reasons why we think OpenBSD is a useful operating system:

• OpenBSD runs on many different hardware platforms.
• OpenBSD is thought of by many security professionals as the most secure UNIX-like operating system, as the result of a never-ending comprehensive source code security audit.
• OpenBSD is a full-featured UNIX-like operating system available in source form at no charge.
• OpenBSD integrates cutting-edge security technology suitable for building firewalls and private network services in a distributed environment.
• OpenBSD benefits from strong ongoing development in many areas, offering opportunities to work with emerging technologies with an international community of programmers and end-users.
• OpenBSD attempts to minimize the need for customization and tweaking. For the vast majority of users, OpenBSD "Just Works" on their hardware for their application. Not only is tweaking and customizing rarely needed, it is actively discouraged.

However, whether OpenBSD is right for you is a question that only you can answer.

What is included with OpenBSD?

OpenBSD is distributed with a number of third-party software products, including:

• X.org 7.7, the X Window environment, with local patches. Installed with the x*.tgz install file sets.
• GCC versions 4.2.1 or 3.3.6 (depending on your platform) GNU C Compiler. Installed as part of the comp57.tgz file set.
• Perl 5.20.1, with patches and improvements from the OpenBSD team.
• LibreSSL, OpenBSD's replacement for OpenSSL.
• SQLite 3.8.6, with patches and improvements from the OpenBSD team.
• NSD 4.1.1 authoritative DNS server.
• Unbound 1.5.2
• Sudo v1.7.2p8, allowing users to run individual commands as root.
• Ncurses 5.7
• Binutils 2.15 with patches.
• gdb 6.3 with patches.
• Less 458 with patches.
• Awk Aug 10, 2011 version
• OpenSSH 6.8
• OpenSMTPD v5.4.4 Secure, simple and reliable Mail Transport Agent (MTA).
• OpenNTPD Secure and simple Network Time Protocol implementation.
• OpenBGPD and OpenOSPFD routing applications.
• httpd, OpenBSD's own web server

As can be seen, the OpenBSD team often patches third-party products (typically) to improve the security or quality of the code. In some cases, the user will see no difference in operation, in other cases, there ARE operational differences which may impact some users. Keep these enhancements in mind before blindly adding different versions of the same software. You may get a bigger version number, but a less secure system.

Of course, additional applications can be added through the OpenBSD packages and ports system.
