   o xcompmgr(1) was added to xenocara.

- New functionality:
   o The libc resolver(3) may now be forced to perform lookups by TCP
     only using a new resolv.conf(5) option. The nameserver declaration
     in resolv.conf(5) has also been extended to allow specification
     of non-default nameserver ports.
   o apropos(1) has two new options (-S and -s) to allow searching by
     machine architecture and manual section.
   o aucat(1) now has audio server capability. Audio devices can be
     shared between multiple applications. Applications can run natively
     on fixed sample rate devices or on devices with unusual encodings.
     Multi-channel audio devices can be split into smaller independent
   o aucat(1) now has a deviceless mode, in which it can be used as a

     sector sizes other than 512 bytes.
   o Disklabels are now correctly placed and found on most devices,
     e.g. CD's, that have sector sizes other than 512 bytes.

- Assorted improvements and code cleanup:
   o malloc(3) has gained new attack mitigation measures; critical
     bookkeeping structures are protected at runtime using mprotect(2)
     and allocated at random addresses where possible.
   o A new version of the gdtoa code has been integrated, bringing
     better C99 support to printf(3) and friends.
   o Vastly improved C99 support in libm, including complex math support.

- Install/Upgrade process changes:
   o crunchgen(1) and crunchide(1) have been merged into crunchgen(8),
     which is now built and installed by default.
   o mksuncd(1) now lives in base and is installed by default.
   o CD-ROM installs are now supported on SGI.
   o Accept initial root passwords containing backslash characters.
   o Install now allows multiple interfaces to be configured with dhcp(8).
   o Upgrades now use the minimal protocols(5) and services(5) files
     provided on the install media.
   o The install media no longer contain a disktab(5) file.
   o Serial console speed is correctly determined on macppc.

- OpenSSH 5.2:
   o New features:
     o Added an option to ssh(1) to force logging to syslog rather
       than stderr.
     o The sshd_config(5) ForceCommand directive now accepts commandline
       arguments for the internal-sftp server.
     o The ssh(1) ~C escape commandline now support runtime creation of
       dynamic port forwards.
     o Support the SOCKS4A protocol in ssh(1) dynamic forwards.
     o Support remote port forwarding with a listen port of '0'.
     o sshd(8) now supports setting PermitEmptyPasswords and
       AllowAgentForwarding in Match blocks.
   o The following significant bugs have been fixed in this release:
     o Repair a ssh(1) crash introduced in openssh-5.1 when the
       client is sent a zero-length banner.
     o The and protocol
       extensions are now only sent to peers that identify
       themselves as OpenSSH.
     o Avoid printing "Non-public channel" warnings in sshd(8), since ssh(1)
       has sent incorrect channel numbers since ~2004; make ssh(1) send the
       correct channel number for SSH2_MSG_CHANNEL_SUCCESS and
     o Avoid double-free in ssh(1) ~C escape -L handler.
     o Correct fail-on-error behaviour in sftp(1) batchmode for remote
       stat operations.
     o Avoid hang in ssh(1) when attempting to connect to a server that
       has MaxSessions set to zero.

- Over 5,500 ports, minor robustness improvements in package tools.
   o Many pre-built packages for each architecture:
     i386:   5379    sparc64:  5174    alpha: 5132    sh:     1543
     amd64:  5312    powerpc:  5162    sparc: 2651    mips64: 3278

If you'd like to see a list of what has changed between OpenBSD 4.4
and 4.5, look at

Even though the list is a summary of the most important changes
made to OpenBSD, it still is a very very long list.
We provide patches for known security threats and other important
issues discovered after each CD release.  As usual, between the
creation of the OpenBSD 4.5 FTP/CD-ROM binaries and the actual 4.5
release date, our team found and fixed some new reliability problems
(note: most are minor and in subsystems that are not enabled by
default).  Our continued research into security means we will find
new security problems -- and we always provide patches as soon as
possible.  Therefore, we advise regular visits to

Security patch announcements are sent to the
mailing list.  For information on OpenBSD mailing lists, please see:
OpenBSD 4.5 is also available on CD-ROM.  The 3-CD set costs $50 CDN and
is available via mail order and from a number of contacts around the
world.  The set includes a colourful booklet which carefully explains the
installation of OpenBSD.  A new set of cute little stickers is also
included (sorry, but our FTP mirror sites do not support STP, the Sticker
Transfer Protocol).  As an added bonus, the second CD contains an audio
track, a song entitled "Games".  MP3 and OGG versions of the audio track
can be found on the first CD.

Lyrics (and an explanation) for the songs may be found at:

Profits from CD sales are the primary income source for the OpenBSD
project -- in essence selling these CD-ROM units ensures that OpenBSD
will continue to make another release six months from now.

The OpenBSD 4.5 CD-ROMs are bootable on the following four platforms:

 o i386
 o amd64
 o macppc
 o sparc64

(Other platforms must boot from floppy, network, or other method).

For more information on ordering CD-ROMs, see:

The above web page lists a number of places where OpenBSD CD-ROMs
can be purchased from.  For our default mail order, go directly to:

All of our developers strongly urge you to buy a CD-ROM and support
our future efforts.  Additionally, donations to the project are
highly appreciated, as described in more detail at:
For those unable to make their contributions as straightforward gifts,
the OpenBSD Foundation ( is a Canadian
not-for-profit corporation that can accept larger contributions and
issue receipts.  In some situations, their receipt may qualify as a
business expense writeoff, so this is certainly a consideration for
some organizations or businesses.  There may also be exposure benefits
since the Foundation may be interested in participating in press releases.
In turn, the Foundation then uses these contributions to assist OpenBSD's
infrastructure needs.  Contact the foundation directors at for more information.
The OpenBSD distribution companies also sell tshirts and polo shirts.
And our users like them too.  We have a variety of shirts available,
with the new and old designs, from our web ordering system at, as
described above.

The OpenBSD 4.5 t-shirts are available now.  We also sell our older
shirts, as well as a selection of OpenSSH t-shirts.
If you choose not to buy an OpenBSD CD-ROM, OpenBSD can be easily
installed via FTP.  Typically you need a single small piece of boot
media (e.g., a boot floppy) and then the rest of the files can be
installed from a number of locations, including directly off the
Internet.  Follow this simple set of instructions to ensure that
you find all of the documentation you will need while performing
an install via FTP.  With the CD-ROMs, the necessary documentation
is easier to find.

1) Read either of the following two files for a list of ftp
  mirrors which provide OpenBSD, then choose one near you:

  As of May 1, 2009, the following ftp mirror sites have the 4.5 release:       Sweden     NYC, USA     CO, USA     CA, USA                    IL, USA

       The release is also available at the master site:  Alberta, Canada

       However it is strongly suggested you use a mirror.

  Other mirror sites may take a day or two to update.

2) Connect to that ftp mirror site and go into the directory
  pub/OpenBSD/4.5/ which contains these files and directories.
  This is a list of what you will see:

       ANNOUNCEMENT   amd64/         macppc/        sys.tar.gz
       Changelogs/    armish/        mvme68k/       tools/
       HARDWARE       ftplist        packages/      vax/
       PACKAGES       hp300/         ports.tar.gz   xenocara.tar.gz
       PORTS          hppa/          root.mail      zaurus/
       README         i386/          sparc/
       SIZES          landisk/       sparc64/
       alpha/         mac68k/        src.tar.gz

  It is quite likely that you will want at LEAST the following
  files which apply to all the architectures OpenBSD supports.

       README          - generic README
       HARDWARE        - list of hardware we support
       PORTS           - description of our "ports" tree
       PACKAGES        - description of pre-compiled packages
       root.mail       - a copy of root's mail at initial login.
                         (This is really worthwhile reading).

3) Read the README file.  It is short, and a quick read will make
  sure you understand what else you need to fetch.

4) Next, go into the directory that applies to your architecture,
  for example, i386.  This is a list of what you will see:

       INSTALL.i386    cd45.iso        floppyB45.fs    pxeboot*
       INSTALL.linux   cdboot*         floppyC45.fs    xbase45.tgz
       MD5             cdbr*           game45.tgz      xetc45.tgz
       base45.tgz      cdemu45.iso     index.txt       xfont45.tgz
       bsd*            comp45.tgz      install45.iso   xserv45.tgz*         etc45.tgz       man45.tgz       xshare45.tgz
       bsd.rd*         floppy45.fs     misc45.tgz

  If you are new to OpenBSD, fetch _at least_ the file INSTALL.i386
  and the appropriate floppy*.fs or install45.iso files.  Consult the
  INSTALL.i386 file if you don't know which of the floppy images
  you need (or simply fetch all of them).

  If you use the install45.iso file (roughly 200MB in size), then you
  do not need the various *.tgz files since they are contained on that
  one-step ISO-format install CD.

5) If you are an expert, follow the instructions in the file called
  README; otherwise, use the more complete instructions in the
  file called INSTALL.i386.  INSTALL.i386 may tell you that you
  need to fetch other files.

6) Just in case, take a peek at:

  This is the page where we talk about the mistakes we made while
  creating the 4.5 release, or the significant bugs we fixed
  post-release which we think our users should have fixes for.
  Patches and workarounds are clearly described there.

Note: If you end up needing to write a raw floppy using Windows,
     you can use "fdimage.exe" located in the pub/OpenBSD/4.5/tools
     directory to do so.
X.Org has been integrated more closely into the system.  This release
contains X.Org 7.4.  Most of our architectures ship with X.Org, including
amd64, sparc, sparc64 and macppc.  During installation, you can install
X.Org quite easily.  Be sure to try out xdm(1) and see how we have
customized it for OpenBSD.
The OpenBSD ports tree contains automated instructions for building
third party software.  The software has been verified to build and
run on the various OpenBSD architectures.  The 4.5 ports collection,
including many of the distribution files, is included on the 3-CD
set.  Please see the PORTS file for more information.

Note: some of the most popular ports, e.g., the Apache web server
and several X applications, come standard with OpenBSD.  Also, many
popular ports have been pre-compiled for those who do not desire
to build their own binaries (see BINARY PACKAGES, below).
A large number of binary packages are provided.  Please see the PACKAGES
file ( for more details.
The CD-ROMs contain source code for all the subsystems explained
above, and the README (
file explains how to deal with these source files.  For those who
are doing an FTP install, the source code for all four subsystems
can be found in the pub/OpenBSD/4.5/ directory:

       xenocara.tar.gz     ports.tar.gz   src.tar.gz     sys.tar.gz
OpenBSD 4.5 includes artwork and CD artistic layout by Ty Semaka,
who also arranged an audio track on the OpenBSD 4.5 CD set.  Ports
tree and package building by Jasper Lievisse Adriaanse, Michael Erdely,
Simon Bertrang, Stuart Henderson, Antoine Jacoutot, Robert Nagy,
Nikolay Sturm, and Christian Weisgerber.  System builds by Theo de Raadt,
Mark Kettenis, and Miod Vallat.  X11 builds by Todd Fries and Miod Vallat.
ISO-9660 filesystem layout by Theo de Raadt.

We would like to thank all of the people who sent in bug reports, bug
fixes, donation cheques, and hardware that we use.  We would also like
to thank those who pre-ordered the 4.5 CD-ROM or bought our previous
CD-ROMs.  Those who did not support us financially have still helped
us with our goal of improving the quality of the software.
