--------------------------------------------------------------------------------
1.1-什么是OpenBSD?

OpenBSD 工程创建的一个免费、多平台、基于4.4BSD的类Unix操作系统。我们的目标在于强调正确性、安全性、标准化以及可移植性。OpenBSD支持包括SVR4(Solaris),FreeBSD,Linux,BSDI,SunOS和HPUX等大部分二进制的模拟。

OpenBSD， NetBSD, FreeBSD是同门三兄弟！OpenBSD以安全着称， 支持的平台很多！现在主要有三个分支：stable, release, current

1.2-OpenBSD能运行于什么平台上？

OpenBSD 3.4可运行于以下平台：
● alpha - 仅FTP
● amd64 - 可直接从CD启动 3.5新增
● cats - 仅FTP 3.5新增
● hp300 - 仅FTP
● hppa - 仅FTP
● i386 - 可直接从CD启动
● mac68k - 仅FTP
● macppc - 可直接从CD启动
● sparc - 可直接从CD启动
● sparc64 - 可直接从CD启动
● mvme88k - 仅FTP 3.5新增
● alpha - 仅FTP
● vax

只有一些平台支持从CD启动。查看本FAQ第三章来了解如何获得关于获得OpenBSD CD的更多信息。

OpenBSD以前的版本同样可运行于：
● amiga - 3.2 release后开始移除
● sun3 - 2.9 release后开始移除
● arc - 2.3 release后开始移除
● pmax - 2.7 release后开始移除
OpenBSD目前还不支持多处理器。查看Chapter 8,SMP来获得更多信息。

1.3-OpenBSD真的免费吗？
　　OpenBSD是完全免费的。二进制文件(binaries)是免费的。源代码是免费的。OpenBSD的任何部分都允许在合理的版权限制下自由分发。这包括可以重新使用大部分OpenBSD源代码树，无论是私用还是商用。除了原始的BSD许可外，OpenBSD没有任何其他的限制。一些按照严格许可而写的软件不能包含进OpenBSD的正规发行版中。这样有利于保护OpenBSD的安全免费使用。例如，OpenBSD可以自由免费的用于个人使用、学术研究、政府机构、非赢利性组织或者商业组织。

　　想进一步的了解其他更流行的许可证，请看:http://www.openbsd.org/policy.asp.
　 OpenBSD的维护者主要通过自身来支持OpenBSD Project.这包括为此工程写程序所花费的时间，用于维护众多ports的设备、以及回答问题和研究用户错误报告所花的时间。OpenBSD的开发者们并非都十分富有，并且甚至是贡献一点点时间、设备、或者资源都会使事情大不一样。

1.4-我为什么想要使用OpenBSD?

　新用户通常会想知道OpenBSD是否会优于其他的类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争论着的话题。无论如何，请不要在邮件列表中问这个问题！

　下面是我们认为OpenBSD是一个很有用的操作系统的一些理由。OpenBSD是否适合你，只有你自己能回答！

●OpenBSD能运行在许多不同的硬件平台上。
●通过对OpenBSD全部源代码的安全审查，大部分的安全专家认为OpenBSD是最安全的类UNIX操作系统。
●OpenBSD是一个充满特色的类Unix操作系统,其原代码完全免费。
●OpenBSD有最前沿的安全技术，适合于做防火墙和分布式环境下的私有网络服务。
●OpenBSD受益于来自不同地方的强大的持续开发，为因特网社区上的程序员和终用户提供了用最新的技术进行开发的机会。
●OpenBSD为普通用户参与开发和产品测试提供机会。

What's New
This is a partial list of new features and systems included in OpenBSD 3.8. For a comprehensive list, see the changelog leading to 3.8.


Improved hardware support, including:
New aps driver for the built-in accelerometer found in some IBM ThinkPad laptops.
New art driver for Accom Networks Artery T1 and E1 cards.
New auixp driver for the ATI IXP series integrated AC'97 audio controller.
New ciss driver for Compaq Smart ARRAY 5 and 6 RAID controllers.
New epic driver for SMC 83C170 ethernet adapters.
New ichwdt driver for Intel 6300ESB ICH watchdog timer.
New pcn driver for the AMD Am79c97x (PCnet) ethernet adapters.
New safte driver for SCSI Accessed Fault-Tolerant Enclosures, and a rewritten ses driver for SCSI Enclosure Services, both allowing monitoring through sysctl and sensorsd.
New ueagle driver for Analog Devices Eagle ADSL modems.
New uipaq driver for iPAQ USB serial.
New viasio driver for VIA VT1211 LPC Super I/O hardware sensors.
New zaudio driver for the built-in Zaurus audio CODEC.
Improved com driver for serial port PCMCIA cards, such as cellular modems on Zaurus.
Improved support for many umass devices.
Updated driver from X.Org for the Intel i810 family graphics chipset, including support for the external VGA output on laptops.

New tools:
bioctl(8), a RAID management interface.
ipsecctl(8), a simple IPsec management tool.
stat(1), displaying file status obtained from stat(2) or lstat(2).
hostapd(8), a wireless Host Access Point daemon.
ifstated(8), a daemon monitoring ethernet interfaces status.
watchdogd(8), companion to the hardware watchdog devices.
ztsscale(8), a tool to calibrate the Zaurus touch screen.
xidle(1), a tool to run a program on X inactivity.
gzsig(1), create and verify cryptographic signatures built into gzip file headers.
sasyncd(8), a daemon to synchronize IPSec SA's for failover gateways.

New functionality:
mount_udf(8), providing UDF (DVD) filesystem support.
Network interface aggregation, using the virtual trunk(4) interface.
Partial wide character and locale support in the C and C++ libraries.
wd(4) disks have the security feature frozen before being attached to prevent malicious users setting a password that would prevent the contents of the drive from being accessed.
On the OpenBSD/sparc64 platform, StackGhost buffer overflow exploit protection has been added.
zaudio(4) changes the mute values if the headphones are plugged in or out.

New functionality for ospfd(8), the Open Shortest Path First Daemon:
ospfd is now able to redistribute static, connected and default routes.
ospfctl is now able to display all relevant information.
Interoperability with cisco and Extreme has been improved.
Support for parsing and displaying parsed configuration file, similar to bgpd.
Support for cryptographic authentication has been added.
Interface finite state machine has been reworked, primarily to improve interoperability.
The performance of the shortest path first calculation has been improved.
Numerous bugs have been discovered and fixed during the last 6 months.

New functionality for bgpd(8), the Border Gateway Protocol Daemon:
bgpd is now able to redistribute static and connected routes dynamically.
Full route label support; pf(4) can filter based on information bgpd attaches to the routes.
An additional per prefix weight has been added used to evaluate prefixes with equal AS path length.
New route decision tunable rde med compare always to force bgpd to compare the MED independent of the peer AS.
IPv6 support.

Assorted improvements and code cleanup:
malloc(3) has been rewritten to use the mmap(2) system call, introducing unpredictable allocation addresses and guard pages, which helps in detecting heap based buffer overflows and prevents various types of attacks.
libc(3) source code has been converted to ANSI C.
realpath(3) is now thread safe.
Several pathname races and potential buffer handling problems have been fixed in pax(1).
Problems with signal delivery on OpenBSD/sparc and OpenBSD/sparc64 have been fixed.
Reliability of signal handlers using floating point on OpenBSD/i386 and OpenBSD/macppc has been improved.
NFS write performance has been improved greatly.
Countermeasures against various blind ICMP attacks have been implemented.

OpenSSH 4.2:
Adds a new compression method that delays the start of zlib compression until the user has been authenticated successfully. The new method ("Compression delayed") is on by default in the server and eliminates the risk of any zlib vulnerability leading to a compromise of the server from unauthenticated users.
Added support for the improved arcfour cipher modes from draft-harris-ssh-arcfour-fixes-02. The improves the cipher's resistance to a number of attacks by discarding early keystream output.
Many improvements to connection multiplexing, including a new opportunistic multiplexing mode, automatic fallback to plain connections when multiplexing fails and support for multiplexed X11 and agent forwarding.
Many additional bug fixes and improvements, as described in the release announcement.

Over 3200 ports, 3000 pre-built packages, improved package tools.

As usual, many improvements in manual pages and other documentation.
