Many people have received their 4.6 CDs in the mail by now, and we
really don't want them to be without the full package repository.

- OpenBSD 4.6 RELEASED -------------------------------------------------

Oct 18, 2009.

We are pleased to announce the official release of OpenBSD 4.6.
This is our 26th release on CD-ROM (and 27th via FTP).  We remain

- New tools:
    o Added smtpd(8), a new privilege-separated SMTP daemon.
    o Imported the tmux(1) terminal multiplexer, replacing window(1).

- New functionality:
    o httpd(8) can now serve files larger than 2GB in size.
    o Mice with many buttons are now supported by wsmoused(8).
    o New "nfsserver" and "nfsclient" views have been added to systat(1).
    o Automatic partition allocation has been added to disklabel(8), with a
      variety of smart heuristics.
    o An undo command has been added to disklabel(8), which reverts the
      label back to its previous state.
    o When running in auto-mode, sysmerge(8) will now install binary files
      from X sets automatically.
    o sysmerge(8) now creates a report summary file in the work directory.
    o httpd(8) now drops privileges to www/www rather than nobody/nogroup
      if the User/Group entries are not present within the configuration file.
    o ELF based platforms now generate ELF core dumps and gdb(1) is now able
      to read ELF core dumps.

      a new connection.
    o relayd(8) now allows both UDP and TCP redirections.
    o SSL sessions are now maintained by relayd(8) for each checked host,
      resulting in subsequent checks being lighter and faster on the server.
    o Added support to relayd(8) for client-side TCP connections from relays.
    o Added support to relayd(8) for specifying a CA file to verify SSL server
      certificates when connecting as a client from relays.

- pf(4) improvements:
    o Enabled pf(4) by default in the rc.conf(8).
    o Removed pf(4) scrub rules, and only do one kind of packet reassembly.
      Rulesets with scrub rules need to be modified because of this.
    o Regular rules can now have per-rule scrub options.
    o Added new "match" keyword which only applies rule options but does
      not change the current pass/block state.
    o Make all pf(4) operations transactional to improve atomicity of reloads.
    o Stricter pf(4) checking for ICMP and ICMPv6 packets.
    o Various improvements to pfsync(4) to lower sync traffic bandwidth and
      optionally allow active-active firewall setups.
    o Fix pf(4) scrub max-mss for IPv6 traffic.

- softraid(4) improvements:
    o Rebuild support has been added and RAID 1 volumes can now be rebuilt.

      chunk ordering now being respected. Duplicated chunks and version
      mismatches are also handled gracefully.
    o Volumes with missing members are now brought online.

- OpenBGPD, OpenOSPFD and other routing daemon improvements:
    o In bgpd(8), rework most of the RDE to allow multiple RIBs.
      It is possible to filter per-RIB and attach neighbors to a specific RIB.
    o Added an option to bgpd(8) to change the "connect-retry" timer.
    o Allow bgpd.conf(5) and bgpctl(8) to contain 32-bit ASN numbers written in
      ASPLAIN format.
    o Fix bgpd(8) to correctly encode MP unreachable NLRI so IPv6 prefixes get
      removed correctly.
    o Changed the behaviour of "redistribute default" for ospfd(8) and ripd(8).
      A default route has to be present in the FIB to be correctly advertised.
    o Make ospfd(8) and ripd(8) track reject and blackhole routes and allow
      them to be redistributed even if pointing to
    o Allow an alternate control socket to be specified for ospfd(8).
    o ospfd(8) can now be bound to an alternate routing domain.
    o Fix ospfd(8) route metric for "redistribute default".
    o Initial version of ldpctl(8) and ldpd(8), a label distribution protocol
      daemon for mpls.
    o Make dvmrpd(8) RDE aware of multicast group members per interface.
    o Added support for pruning in dvmrpd(8).

- Generic Network-Stack improvements:
    o Support for virtual routing and firewalling with the addition of routing
    o Added support for ifconfig(8) to bind an interface to a routing domain.
    o Added support to ping(8), traceroute(8), arp(8), nc(1) and telnet(1) to
      specify which routing domain to use.
    o Allow ifconfig(8) to turn off IPv6 completely for an interface and
      make rtsold(8) turn on inet6 on the interface.
    o Routes track the interface link state.
    o route(8) flush accepts "-iface" or "-priority" to only flush routes
      matching these conditions.
    o Multiple dhclients can now coexist without causing mayhem.
    o Make wireless interfaces have an interface priority of 4 by default.
      Makes them less preferred then wired interfaces.
    o Do not accept IPv4 ICMP redirects by default.
    o Added the MAC address to the log entries in dhclient(8). 
    o Make systat(1) show interface description names in the interface view,
      and add new NFS server and client views.
    o Make tun(4) emulate link state depending on the open and close of the
      device fd.
    o Use pf state-table information to speed up decision on whether a packet
      is to be delivered locally or forwarded.
    o More routing socket checks added to make userland applications more
      resilient to kernel changes.

- Install/Upgrade process changes:
    o The installer has almost been rewritten, primarily with a focus on
      simplifying the installation process.
    o Automatic disk layout can now be used during installation, allowing for
      simple single-disk installs.
    o VLAN support is now available in some installation media.
    o A standard user account can now be created during the install process.

- OpenSSH 5.3:
    o Do not limit home directory paths to 256 characters.
    o Several minor documentation and correctness fixes.

- Over 5,800 ports, minor robustness improvements in package tools.
    o Many pre-built packages for each architecture:
      i386:   5606    sparc64:  5413    alpha: 5346    sh:     1261
      amd64:  5544    powerpc:  5427    sparc: 3711    mips64: 3443
      arm:    5291    hppa:     4790    vax:   1785

- As usual, steady improvements in manual pages and other documentation.

- The system includes the following major components from outside
      o Xenocara (based on X.Org 7.4 + patches, freetype 2.3.9,
        fontconfig 2.6.0, Mesa 7.4.2, xterm 243 and more)

If you'd like to see a list of what has changed between OpenBSD 4.5
and 4.6, 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.

- SECURITY AND ERRATA --------------------------------------------------

we provide patches for known security threats and other important
issues discovered after each CD release.  As usual, between the
creation of the OpenBSD 4.6 FTP/CD-ROM binaries and the actual 4.6
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 security-announce@OpenBSD.org
mailing list.  For information on OpenBSD mailing lists, please see:


- CD-ROM SALES ---------------------------------------------------------

OpenBSD 4.6 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 "Planet of the Users".  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 4.6 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:


- OPENBSD FOUNDATION ---------------------------------------------------

For those unable to make their contributions as straightforward gifts,
the OpenBSD Foundation (http://www.openbsdfoundation.org) 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
directors@openbsdfoundation.org for more information.

- T-SHIRT SALES --------------------------------------------------------

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 4.6 t-shirts are available now.  We also sell our older
shirts, as well as a selection of OpenSSH t-shirts.

- FTP INSTALLS ---------------------------------------------------------

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 Oct 1, 2009, the following ftp mirror sites have the 4.6 release:

	ftp://ftp.stacken.kth.se/pub/OpenBSD/4.6/	Sweden
	ftp://ftp2.usa.openbsd.org/pub/OpenBSD/4.6/	NYC, USA
	ftp://ftp3.usa.openbsd.org/pub/OpenBSD/4.6/	CO, USA
	ftp://ftp5.usa.openbsd.org/pub/OpenBSD/4.6/	CA, USA
	ftp://rt.fm/pub/OpenBSD/4.6/			IL, USA

	The release is also available at the master site:

	ftp://ftp.openbsd.org/pub/OpenBSD/4.6/	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/4.6/ which contains these files and directories.
   This is a list of what you will see:

        ANNOUNCEMENT     armish/          mvme68k/         sparc64/
        Changelogs/      ftplist          mvme88k/         src.tar.gz
        HARDWARE         hp300/           packages/        sys.tar.gz
        PACKAGES         hppa/            ports.tar.gz     tools/
        PORTS            i386/            root.mail        vax/
        README           landisk/         sgi/             xenocara.tar.gz
        alpha/           mac68k/          socppc/          zaurus/
        amd64/           macppc/          sparc/

   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    cd46.iso        floppyB46.fs    pxeboot*
	INSTALL.linux   cdboot*         floppyC46.fs    xbase46.tgz
	MD5             cdbr*           game46.tgz      xetc46.tgz
	base46.tgz      cdemu46.iso     index.txt       xfont46.tgz
	bsd*            comp46.tgz      install46.iso   xserv46.tgz
	bsd.mp*         etc46.tgz       man46.tgz       xshare46.tgz
	bsd.rd*         floppy46.fs     misc46.tgz

   If you are new to OpenBSD, fetch _at least_ the file INSTALL.i386
   and the appropriate floppy*.fs or install46.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 install46.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 4.6 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/4.6/tools
      directory to do so.

- X.ORG FOR MOST ARCHITECTURES -----------------------------------------

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.

- PORTS TREE -----------------------------------------------------------

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 4.6 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).

- BINARY PACKAGES WE PROVIDE -------------------------------------------

A large number of binary packages are provided.  Please see the PACKAGES
file (ftp://ftp.OpenBSD.org/pub/OpenBSD/4.6/PACKAGES) for more details.

- SYSTEM SOURCE CODE ---------------------------------------------------

The CD-ROMs contain source code for all the subsystems explained
above, and the README (ftp://ftp.OpenBSD.org/pub/OpenBSD/4.6/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/4.6/ directory:

        xenocara.tar.gz     ports.tar.gz   src.tar.gz     sys.tar.gz
