OpenBSD项目提供了一个免费, 多平台, 基于4.4BSD的类Unix操作系统。我们的目标注重于正确, 安 全, 标准和可移植。OpenBSD支持包括SVR4(Solaris), FreeBSD, Linux, BSDI, SunOS和HPUX等大部分 二进制的模拟。 本FAQ只针对OpenBSD的最新版本4.5进行讨论。 1.2 - OpenBSD支持哪些平台? OpenBSD 4.5 可以运行在这些平台上: http://www.9971.us/OpenBSD4.5/c/faq1.html（第 1／7 页）2009-5-3 23:00:52 OpenBSD 4.5 FAQ中文版 第一章 - OpenBSD介绍 ● alpha - 仅FTP ● amd64 - 提供CD ● armish - 仅FTP ● hp300 - 仅FTP ● hppa - 仅FTP ● i386 - 提供CD ● landisk - 仅FTP ● mac68k - 仅FTP ● macppc - 提供CD ● mvme68k - 仅FTP ● mvme88k - 仅FTP ● sgi - 仅FTP ● socppc - 仅FTP ● sparc - 仅FTP ● sparc64 - 提供CD ● vax - 仅FTP ● zaurus - 仅FTP 这里提供CD是指该平台提供了官方的CD套件包含一系列软件包。包含基本系统的其它平台CD 镜像文件也可以下载到。 更多可运行OpenBSD的平台信息在这里可以查询到。 人们经常问道为什么我们支持如此众多的"古怪"平台, 简短的回答是:"因为我们想"。如果那些充分 掌握电脑技术的人(某种程度上讲这里的"充分"是指真正"充分"掌握电脑技术的人!)希望在某种平 台上运行和维护OpenBSD, 那么我们会支持这种做法, 因为保持OpenBSD可以在多平台上运行实际 上是很有好处的:当OpenBSD在一个新的平台运行时可以帮助我们检验程序的代码缺陷和可移植性 是否可靠, OpenBSD可以在32位或64位处理器及大型机或微型机上运行, 这些平台囊括了很多不同 的设计体系, 所以OpenBSD支持这些"古怪"平台对我们提高代码质量以便更好的支持"大众"平台是 很有帮助的。 1.3 - OpenBSD真的免费吗? OpenBSD是完全意义上的免费, 二进制代码是免费的, 原代码是免费的, 所有的OpenBSD的相关项 目是完全免费的, 您可以完全免费得在OpenBSD上开发您自己的有偿产品, 包括免费使用OpenBSD 的源程序, 无论您是商业目的或者是个人的用途。OpenBSD的软件使用许可不像老的BSD版本包含 任何隐含的许可限制, 它是完全意义上的免费, OpenBSD的正式发行版里不包含有任何使用限制的 软件, 您是OpenBSD的最终用户, 您可以任意使用, 改编, 二次开发, 并可免费地将开发应用于您的商 业产品。 http://www.9971.us/OpenBSD4.5/c/faq1.html（第 2／7 页）2009-5-3 23:00:52 OpenBSD 4.5 FAQ中文版 第一章 - OpenBSD介绍 人们有时候会问:我们会不会对将我们的免费的程序代码放进商业产品中感觉很烦恼, 答案是, 我们 更愿意我们的高质量代码被广泛采用, 而不是让用户采用糟糕代码的商业软件来解决那些已经被 解决的问题。例如, 就像SSH协议, 如果OpenSSH代码附加了某些限制, SSH协议就不会被人们如此 广泛地采用。 当然这并不意味着我们反对大家提供的经济或硬件方面的援助, 事实上, 那些在自己的产品上采用 OpenBSD代码的商业公司即使提供任何形式的一点点援助也会令我们不胜感激。 更多公共许可方面的信息, 请参阅:OpenBSD Copyright Policy. OpenBSD项目耗费了维护人员自己大量的资金才得以维持。这里面包括编写程序花费的时间, 方 方面面所需的设备, 用户下载OpenBSD所需的网络资源, 以及回答用户问题及处理错误报告所需的 时间等。OpenBSD的开发者并非无忧无虑的有钱人, 如果您能贡献一点点时间, 设备, 资金, 就可能 给OpenBSD带来极大的改观。 1.4 - 为什么我要使用OpenBSD? 通常新用户想知道OpenBSD是否会优于其它的类Unix操作系统, 这个问题在很大程度上是无法回 答的, 并且是一个永无休止的辩论话题。不要, 在任何情况下, 在邮件列表中问这个问题。 下面是为什么我们认为OpenBSD是一个有用的操作系统的一些理由。OpenBSD是否适合您, 只有 您自己能回答自己! ● OpenBSD能运行在许多不同的硬件平台上。 ● 通过从未间断地、广泛地对OpenBSD全部源代码的安全审查, 很多安全专家认为OpenBSD 是最安全的类UNIX操作系统。 ● OpenBSD是免费提供源代码的全功能的类Unix操作系统。 ● OpenBSD整合了最尖端的安全技术, 适用于防火墙和分布式环境下的私有网络服务。 ● 来自不同领域的新技术推动OpenBSD持续发展, 为全球社区上的程序员和最终用户提供了 采用最新的技术进行开发的机会。 ● OpenBSD力求最小化系统定制和调整的工作量, 对绝大多数用户来说OpenBSD可以直接运 行在他们的计算机上提供服务。用户极少真正需要调整和定制, 我们尽力劝阻用户自行优 化和调整系统。 1.5 - 我如何支持OpenBSD? 我们非常感谢那些对OpenBSD项目赞助的个人或组织。他们的公示名单在捐赠页面。 OpenBSD需要来自用户社区的长期的不同类型的支持。如果您认为OpenBSD很好, 我们强烈鼓励 您通过某种方式为OpenBSD做贡献。假如下列建议没有适合您的, 您可以发送邮件到 http://www.9971.us/OpenBSD4.5/c/faq1.html（第 3／7 页）2009-5-3 23:00:52 OpenBSD 4.5 FAQ中文版 第一章 - OpenBSD介绍 [email protected] 。 ● 购买OpenBSD CD。 CD包含了当前发行版的所有内容, 而且可以在许多平台上启动。CD可 以为OpenBSD项目创收, 并且通过邮寄方式可以缓解网络下载方式给OpenBSD服务器带来 的带宽占用, 这个并不昂贵的3-CD套装包含了所有的OpenBSD源码, 提醒一下, 也许您的朋 友们会到您这里来拷贝一份的! ● 捐款。 OpenBSD项目需要长期的捐款以维持设备, 网络带宽和CD出版发行的大量费用, 出 版CD是需要OpenBSD开发者团队前期投入并且现款一次性支付的, 这些前期费用并不能担 保一定可以盈利甚至回本。请给[email protected]发邮件商量怎样捐款,

  • An Introduction to the X Window System Introduction to X's Anatomy
    An Introduction to the X Window System Robert Lupton This is a limited and partisan introduction to ‘The X Window System’, which is widely but improperly known as X-windows, specifically to version 11 (‘X11’). The intention of the X-project has been to provide ‘tools not rules’, which allows their basic system to appear in a very large number of confusing guises. This document assumes that you are using the configuration that I set up at Peyton Hall † There are helpful manual entries under X and Xserver, as well as for individual utilities such as xterm. You may need to add /usr/princeton/X11/man to your MANPATH to read the X manpages. This is the first draft of this document, so I’d be very grateful for any comments or criticisms. Introduction to X’s Anatomy X consists of three parts: The server The part that knows about the hardware and how to draw lines and write characters. The Clients Such things as terminal emulators, dvi previewers, and clocks and The Window Manager A programme which handles negotiations between the different clients as they fight for screen space, colours, and sunlight. Another fundamental X-concept is that of resources, which is how X describes any- thing that a client might want to specify; common examples would be fonts, colours (both foreground and background), and position on the screen. Keys X can, and usually does, use a number of special keys. You are familiar with the way that <shift>a and <ctrl>a are different from a; in X this sensitivity extends to things like mouse buttons that you might not normally think of as case-sensitive.

  • OPENBSD HARDWARE SENSORS FRAMEWORK a Unified and Ready-To-Use System for Hassle-Ee Hardware Monitoring
    OPENBSD HARDWARE SENSORS FRAMEWORK A unified and ready-to-use system for hassle-ee hardware monitoring. Constantine A. Murenin and Raouf Boutaba University of Waterloo AsiaBSDCon 2009 — 12–15 March 2009 — Tokyo, Japan Abstract In this paper, we will discuss the origin, history, design guidelines, API and the device drivers of the hardware sensors framework available in OpenBSD. The framework spans multiple utilities in the base system and the ports tree, is utilised by over 70 drivers, and is considered to be a distinctive and ready-to-use feature that sets OpenBSD apart from many other operating systems, and in its root is inseparable from the OpenBSD experience. 1.

  • Openbsd: Firewall Ridondanti Con CARP E Pfsync Chris Gamboni CISSP [email protected] Tilug.Ch, Bellinzona, 9 Aprile 2005 Cos'è Openbsd ?
    OpenBSD: Firewall ridondanti con CARP e pfsync Chris Gamboni CISSP [email protected] TiLug.ch, Bellinzona, 9 aprile 2005 Cos'è OpenBSD ? ● OpenBSD: – Nasce da un fork di netbsd nel 1995 – Secure by default (1 remote exploit in 8 anni) – Progetto basato in Canada, nessuna restrizione sull’esportazione di crittografia – Una release ogni 6 mesi (3.7 al 1.6.2005) – Si finanzia con la vendita di CD e di gadgets – Progetti collegati: OpenSSH, OpenNTPd, OpenBGPd, OpenOSPFd, etc… Alta disponibilità: CARP e pfsync ● Il firewall è un single point of failure – Quando il firewall è fermo nessuno accede ad internet, gli e-mail sono bloccati, ecc… – Non si può fermare il firewall per aggiornarlo ● OpenBSD, dalla versione 3.5, offre CARP e pfsync che permettono di avere firewalls in parallelo. Quando un firewall si ferma, il firewall di backup ne assume l’identità in modo trasparente. CARP (1) ● Common Address Redundancy Protocol: è il protocollo che si occupa di gestire il failover a livello 2 ed a livello 3. ● Ogni gruppo CARP possiede: – Un indirizzo MAC virtuale – Un indirizzo IP virtuale – Una password CARP (2) ● Ogni interfaccia CARP può avere 3 stati: MASTER, BACKUP e INIT (ifconfig) ● Il master manda messaggi Multicast (224.0.0.18) usando il protocollo IP 112 ● La frequenza di invio dei messaggi è configurabile (default = 1 sec) ● Chi invia messaggi più frequentemente diventa master CARP (3) ● CARP funziona sia con IPv4 sia con IPv6 ● CARP ha anche una funzione arp-balance che può servire per load-balancing, ma solo nella rete locale. ● CARP spedisce messaggi cifrati con SHA-1 HMAC ● CARP, a differenza di HSRP e VRRP, è esente da licenze e brevetti.

  • Free, Functional, and Secure
    Free, Functional, and Secure Dante Catalfamo What is OpenBSD? Not Linux? ● Unix-like ● Similar layout ● Similar tools ● POSIX ● NOT the same History ● Originated at AT&T, who were unable to compete in the industry (1970s) ● Given to Universities for educational purposes ● Universities improved the code under the BSD license The License The license: ● Retain the copyright notice ● No warranty ● Don’t use the author's name to promote the product History Cont’d ● After 15 years, the partnership ended ● Almost the entire OS had been rewritten ● The university released the (now mostly BSD licensed) code for free History Cont’d ● AT&T launching Unix System Labories (USL) ● Sued UC Berkeley ● Berkeley fought back, claiming the code didn’t belong to AT&T ● 2 year lawsuit ● AT&T lost, and was found guilty of violating the BSD license History Cont’d ● BSD4.4-Lite released ● The only operating system ever released incomplete ● This became the base of FreeBSD and NetBSD, and eventually OpenBSD and MacOS History Cont’d ● Theo DeRaadt ○ Originally a NetBSD developer ○ Forked NetBSD into OpenBSD after disagreement the direction of the project *fork* Innovations W^X ● Pioneered by the OpenBSD project in 3.3 in 2002, strictly enforced in 6.0 ● Memory can either be write or execute, but but both (XOR) ● Similar to PaX Linux kernel extension (developed later) AnonCVS ● First project with a public source tree featuring version control (1995) ● Now an extremely popular model of software development anonymous anonymous anonymous anonymous anonymous IPSec ● First free operating system to implement an IPSec VPN stack Privilege Separation ● First implemented in 3.2 ● Split a program into processes performing different sub-functions ● Now used in almost all privileged programs in OpenBSD like httpd, bgpd, dhcpd, syslog, sndio, etc.
