<ul>
<li>The logging subsystem has been largely rewritten, now logging the
translated addresses again instead of the original ones.
<li>match log rules cause a log on the fly, showing the packet exactly
as <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=pf&sektion=4">pf(4)</a> sees it at the moment of evaluating that rule. A packet can also
be logged more than once now.
<li>match log(matches) rules allow the further rule matching to be traced.
<li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=pflog&sektion=4">pflog(4)</a>
now includes the original addresses and ports for packets that have been
rewritten. This is also displayed by
<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=tcpdump&sektion=8">tcpdump(8)</a>.
</ul>

from optimizing
<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=bzero&sektion=3">bzero</a>
calls away.
</ul>
<p>
<li>SCSI improvements:

the completion of pending commands.</li>
<li>Improved hotplug support on <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=mpi&sektion=4">mpi(4)</a> and
<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=mpii&sektion=4">mpii(4)</a>.</li>
<li>Continued iopoolification of SCSI drivers, notably on
<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=umass&sektion=4">umass(4)</a> which improves the
reliability and performance of multi-LUN devices.</li>

<li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=dhcpd&sektion=8">dhcpd(8)</a> no longer listens on interfaces without a broadcast address (e.g. <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=pflog&sektion=4">pflog(4)</a>).
<li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=who&sektion=1">who(1)</a> now displays as much of the hostname as fits on the line.

<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=compat_linux&sektion=8&format=html">compat_linux(8)</a>
system calls to make it possible for newer versions of applications,
such as Skype, to execute.
<li>OpenBSD-specific package documentation is now centralised in
/usr/local/share/doc/pkg-readmes.
</ul>
<p>
<li>Install/Upgrade process changes:
<ul>
<li>Fixed the hppa CD installation process.
<li>Added some more free firmwares to the CD media that could fit them.
<li>Make the macppc upgrade script update the boot blocks (oddly, this
had been broken a very long time and no one noticed).
<li>Teach the install script about the configuration of 802.11 interfaces.
Visible networks can be listed, and even configured for WPA.
<li>The install script now passes collected entropy better to the
system which is booted next.
<li>Upgrade now defaults to checking only the root filesystem.
<li>Upgrade no longer checks filesystems with a fs_passno of 0.
<li>Upgrade now asks if it should proceed even if one or more filesystem mounts fail.
<li>Installer now configures <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=ntpd&sektion=8">ntpd(8)</a> to use all provided time source IPs.
</ul>
<p>
<li>New <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=rc.d&sektion=8">rc.d(8)</a>
for starting, stopping and reconfiguring package daemons:
<ul>
<li>The <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=rc.subr&sektion=8">rc.subr(8)</a>
framework allows for easy creation of rc scripts.
This framework is still evolving.
<li>Only a handful of packages have migrated for now.
<li>rc.local can still be used instead of or in addition to
<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=rc.d&sektion=8">rc.d(8)</a>.
</ul>
<p>
<li>OpenSSH 5.8:
<ul>
<li>New features:
<ul>
<li>Implement Elliptic Curve Cryptography modes for key exchange (ECDH)
and host/user keys (ECDSA) as specified by RFC5656. ECDH and ECDSA
offer better performance than plain DH and DSA at the same
equivalent symmetric key length, as well as much shorter keys.</li>
<li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=sftp&sektion=1">sftp(1)</a>
and
<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=sftp-server&sektion=8">sftp-server(8)</a>:
add a protocol extension to support a hard link operation. It is
available through the "ln" command in the client. The old "ln"
behaviour of creating a symlink is available using its "-s" option
or through the preexisting "symlink" command.</li>
<li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=scp&sektion=1">scp(1)</a>:
Add a new -3 option to scp: Copies between two remote hosts are
transferred through the local host. Without this option the data is
copied directly between the two remote hosts.</li>
<li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=ssh&sektion=1">ssh(1)</a>:
automatically order the hostkeys requested by the client based on
which hostkeys are already recorded in known_hosts. This avoids
hostkey warnings when connecting to servers with new ECDSA keys,
since these are now preferred when learning hostkeys for the first
time.</li>
<li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=ssh&sektion=1">ssh(1)</a>
and
<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=sshd&sektion=8">sshd(8)</a>:
add a new IPQoS option to specify arbitrary TOS/DSCP/QoS values
instead of hardcoding lowdelay/throughput. (bz#1733)</li>
<li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=sftp&sektion=1">sftp(1)</a>:
the sftp client is now significantly faster at performing directory
listings, using OpenBSD glob(3) extensions to preserve the results
of stat(3) operations performed in the course of its execution
rather than performing expensive round trips to fetch them again
afterwards.</li>
<li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=ssh&sektion=1">ssh(1)</a>:
"atomically" create the listening mux socket by binding it on a
temporary name and then linking it into position after listen() has
succeeded. This allows the mux clients to determine that the server
socket is either ready or stale without races. Stale server sockets
are now automatically removed. (also fixes bz#1711)</li>
<li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=ssh&sektion=1">ssh(1)</a>
and
<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=sshd&sektion=8">sshd(8)</a>:
add a <em>KexAlgorithms</em> knob to the client and server
configuration to allow selection of which key exchange methods are
used by
<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=ssh&sektion=1">ssh(1)</a>
and
<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=sshd&sektion=8">sshd(8)</a>
and their order of preference.</li>
<li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=sftp&sektion=1">sftp(1)</a>
and
<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=scp&sektion=1">scp(1)</a>:
factor out bandwidth limiting code from
<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=scp&sektion=1">scp(1)</a>
into a generic bandwidth limiter that can be attached using the
<em>atomicio</em> callback mechanism and use it to add a bandwidth
limit option to
<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=sftp&sektion=1">sftp(1)</a>.
(bz#1147)</li>
</ul>
<li>The following significant bugs have been fixed in this release:
<ul>
<li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=ssh&sektion=1">ssh(1)</a>
and
<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=ssh-agent&sektion=1">ssh-agent(1)</a>:
honour <em>$TMPDIR</em> for client xauth and ssh-agent temporary
directories. (bz#1809)</li>
<li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=ssh&sektion=1">ssh(1)</a>:
avoid <em>NULL</em> deref on receiving a channel request on an
unknown or invalid channel. (bz#1842)</li>
<li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=sshd&sektion=8">sshd(8)</a>:
remove a <em>debug()</em> that pollutes stderr on client connecting
to a server in debug mode. (bz#1719)</li>
<li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=scp&sektion=1">scp(1)</a>:
pass through ssh command-line flags and options when doing
remote-remote transfers, e.g. to enable agent forwarding which is
particularly useful in this case. (bz#1837)</li>
<li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=sftp-server&sektion=8">sftp-server(8)</a>:
<em>umask</em> should be parsed as octal.</li>
<li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=sftp&sektion=1">sftp(1)</a>:
escape '[' in filename tab-completion.</li>
<li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=ssh&sektion=1">ssh(1)</a>:
Typo in confirmation message. (bz#1827)</li>
<li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=sshd&sektion=8">sshd(8)</a>:
prevent <em>free()</em> of string in <em>.rodata</em> when
overriding <em>AuthorizedKeys</em> in a <em>Match</em> block.</li>
<li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=sshd&sektion=8">sshd(8)</a>:
Use default shell <em>/bin/sh</em> if <em>$SHELL</em> is "".</li>
<li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=ssh&sektion=1">ssh(1)</a>:
kill proxy command on <em>fatal()</em> (we already killed it on
clean exit).</li>
<li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=ssh&sektion=1">ssh(1)</a>:
install a <em>SIGCHLD</em> handler to reap expired child process.
(bz#1812)</li>
<li>Support building against openssl-1.0.0a</li>
<li>Fix vulnerability in legacy certificate signing introduced in
OpenSSH-5.6 and found by Mateusz Kocielski.</li>
</ul>
</ul>
<p>
<li>Mandoc 1.10.9:
<ul>
<li>New integrated <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=tbl&sektion=7">tbl(7)</a> parser and renderer.
<li>Support the <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=roff&sektion=7">roff(7)</a> .de, .rm, and .so requests.
<li>Support all roff code used in the standard <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=pod2man&sektion=1">pod2man(1)</a> preamble.
<li>Fully support roff quoting in <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=man&sektion=7">man(7)</a> documents.

Following this are the instructions which you would have on a piece of
paper if you had purchased a CDROM set instead of doing an alternate
form of install. The instructions for doing an FTP (or other style
of) install are very similar; the CDROM instructions are left intact
so that you can see how much easier it would have been if you had
purchased a CDROM instead.

Quick installer information for people familiar with OpenBSD, and the
use of the "disklabel -E" command. If you are at all confused when
installing OpenBSD, read the relevant INSTALL.* file as listed above!
<p>
<h3><font color="#e00000">OpenBSD/i386:</font></h3>
<ul>
Play with your BIOS options to enable booting from a CD. The OpenBSD/i386
release is on CD1. If your BIOS does not support booting from CD, you will need
to create a boot floppy to install from. To create a boot floppy write
<i>CD1:4.9/i386/floppy49.fs</i> to a floppy and boot via the floppy drive.
<p>
Use <i>CD1:4.9/i386/floppyB49.fs</i> instead for greater SCSI controller
support, or <i>CD1:4.9/i386/floppyC49.fs</i> for better laptop support.
<p>
If you can't boot from a CD or a floppy disk,
you can install across the network using PXE as described in
the included INSTALL.i386 document.
<p>
If you are planning on dual booting OpenBSD with another OS, you will need to
read INSTALL.i386.
<p>
To make a boot floppy under MS-DOS, use the "rawrite" utility located
at <i>CD1:4.9/tools/rawrite.exe</i>. To make the boot floppy under a Unix OS,
use the
<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=dd&sektion=1">dd(1)</a>
utility. The following is an example usage of
<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=dd&sektion=1">dd(1)</a>,
where the device could be "floppy", "rfd0c", or
"rfd0a".
<ul><pre>
# <strong>dd if=<file> of=/dev/<device> bs=32k</strong>
</pre></ul>
<p>
Make sure you use properly formatted perfect floppies with NO BAD BLOCKS or
your install will most likely fail. For more information on creating a boot
floppy and installing OpenBSD/i386 please refer to
<a href="faq/faq4.html#MkFlop">FAQ 4.3.2</a>.
</ul>
<p>
<h3><font color="#e00000">OpenBSD/amd64:</font></h3>
<ul>
The 4.9 release of OpenBSD/amd64 is located on CD2.
Boot from the CD to begin the install - you may need to adjust
your BIOS options first.
If you can't boot from the CD, you can create a boot floppy to install from.
To do this, write <i>CD2:4.9/amd64/floppy49.fs</i> to a floppy, then
boot from the floppy drive.
<p>
If you can't boot from a CD or a floppy disk,
you can install across the network using PXE as described in the included
INSTALL.amd64 document.
<p>
If you are planning to dual boot OpenBSD with another OS, you will need to
read INSTALL.amd64.
</ul>
<p>
<h3><font color="#e00000">OpenBSD/macppc:</font></h3>
<ul>
Put CD2 in your CDROM drive and poweron your machine while holding down the
<i>C</i> key until the display turns on and shows <i>OpenBSD/macppc boot</i>.
<p>
Alternatively, at the Open Firmware prompt, enter <i>boot cd:,ofwboot
/4.9/macppc/bsd.rd</i>
</ul>
<p>
<h3><font color="#e00000">OpenBSD/sparc64:</font></h3>
<ul>
Put CD3 in your CDROM drive and type <i>boot cdrom</i>.
<p>
If this doesn't work, or if you don't have a CDROM drive, you can write
<i>CD3:4.9/sparc64/floppy49.fs</i> or <i>CD3:4.9/sparc64/floppyB49.fs</i>
(depending on your machine) to a floppy and boot it with <i>boot
floppy</i>. Refer to INSTALL.sparc64 for details.
<p>
Make sure you use a properly formatted floppy with NO BAD BLOCKS or your install
will most likely fail.
<p>
You can also write <i>CD3:4.9/sparc64/miniroot49.fs</i> to the swap partition on
the disk and boot with <i>boot disk:b</i>.
<p>
If nothing works, you can boot over the network as described in INSTALL.sparc64.
</ul>
<p>
<h3><font color="#e00000">OpenBSD/alpha:</font></h3>
<ul>
<p>Write <i>FTP:4.9/alpha/floppy49.fs</i> or
<i>FTP:4.9/alpha/floppyB49.fs</i> (depending on your machine) to a diskette and
enter <i>boot dva0</i>. Refer to INSTALL.alpha for more details.

<h3><font color="#e00000">OpenBSD/armish:</font></h3>
<ul>
<p>
After connecting a serial port, Thecus can boot directly from the network
either tftp or http. Configure the network using fconfig, reset,
then load bsd.rd, see INSTALL.armish for specific details.
IOData HDL-G can only boot from an EXT-2 partition. Boot into linux
and copy 'boot' and bsd.rd into the first partition on wd0 (hda1)
then load and run bsd.rd, preserving the wd0i (hda1) ext2fs partition.
More details are available in INSTALL.armish.
</ul>
<p>
<h3><font color="#e00000">OpenBSD/hp300:</font></h3>

</pre></ul>
<p>
If your SPARC system does not have a CD drive, you can alternatively boot from floppy.
To do so you need to write <i>floppy49.fs</i> to a floppy.
For more information see <a href="faq/faq4.html#MkFlop">FAQ 4.3.2</a>.
To boot from the floppy use one of the two commands listed below,
depending on the version of your ROM.
<ul><pre>
ok <strong>boot floppy</strong>
or
> <strong>b fd()</strong>
</pre></ul>
<p>
Make sure you use a properly formatted floppy with NO BAD BLOCKS or your install
will most likely fail.
<p>
If your SPARC system doesn't have a floppy drive nor a CD drive, you can either
setup a bootable tape, or install via network, as told in the
INSTALL.sparc file.
</ul>
<p>
<h3><font color="#e00000">OpenBSD/vax:</font></h3>

openbsd49_arm.ipk package. Reboot, then run it. Read INSTALL.zaurus
for a few important details.
</ul>
<p>
<h3><font color="#e00000">Notes about the source code:</font></h3>
<ul>
src.tar.gz contains a source archive starting at /usr/src. This file
contains everything you need except for the kernel sources, which are
in a separate archive. To extract:
<p>
<ul><pre>
# <strong>mkdir -p /usr/src</strong>
# <strong>cd /usr/src</strong>
# <strong>tar xvfz /tmp/src.tar.gz</strong>
</pre></ul>
<p>
sys.tar.gz contains a source archive starting at /usr/src/sys.
This file contains all the kernel sources you need to rebuild kernels.
To extract:
<p>
<ul><pre>
# <strong>mkdir -p /usr/src/sys</strong>
# <strong>cd /usr/src</strong>
# <strong>tar xvfz /tmp/sys.tar.gz</strong>
</pre></ul>
<p>
Both of these trees are a regular CVS checkout. Using these trees it
is possible to get a head-start on using the anoncvs servers as
described <a href="anoncvs.html">here</a>.
Using these files
results in a much faster initial CVS update than you could expect from
a fresh checkout of the full OpenBSD source tree.
<p>
</ul>
<a name="upgrade"></a>
<hr>
<p>
<h3><font color="#0000e0">How to upgrade</font></h3>
<p>
If you already have an OpenBSD 4.8 system, and do not want to reinstall,
upgrade instructions and advice can be found in the
<a href="faq/upgrade49.html">Upgrade Guide</a>.
<a name="ports"></a>
<hr>
<p>
<h3><font color="#0000e0">Ports Tree</font></h3>
<p>
A ports tree archive is also provided. To extract:
<p>
<ul><pre>
# <strong>cd /usr</strong>
# <strong>tar xvfz /tmp/ports.tar.gz</strong>
# <strong>cd ports</strong>
</pre></ul>
<p>
The <i>ports/</i> subdirectory is a checkout of the OpenBSD ports tree. Go
read the <a href="faq/ports/index.html">ports</a> page
if you know nothing about ports
at this point. This text is not a manual of how to use ports.
Rather, it is a set of notes meant to kickstart the user on the
OpenBSD ports system.
<p>
The <i>ports/</i> directory represents a CVS (see the manpage for
<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=cvs&apropos=0&sektion=1&manpath=OpenBSD+Current&arch=i386">
cvs(1)</a> if
you aren't familiar with CVS) checkout of our ports. As with our complete
source tree, our ports tree is available via anoncvs. So, in
order to keep current with it, you must make the <i>ports/</i> tree
available on a read-write medium and update the tree with a command
like:
<p>
<ul><pre>
# <strong>cd [portsdir]/; cvs -d [email protected]:/cvs update -Pd -rOPENBSD_4_9</strong>
</pre></ul>
<p>
[Of course, you must replace the local directory and server name here
with the location of your ports collection and a nearby anoncvs
server.]
<p>
Note that most ports are available as packages through FTP. Updated
packages for the 4.9 release will be made available if problems arise.
<p>
If you're interested in seeing a port added, would like to help out, or just
would like to know more, the mailing list [email protected] is a good
place to know.
