<h3><font color="#0000e0">What's New</font></h3>
<p>
This is a partial list of new features and systems included in OpenBSD 3.5.
For a comprehensive list, see the <a href="plus.html">changelog</a> leading
to 3.5.
<p>
<ul>
<li> New platforms:
<ul>
<li><a href="http://www.openbsd.org/amd64.html">OpenBSD/amd64</a>
<li><a href="http://www.openbsd.org/cats.html">OpenBSD/cats</a>
</ul>
<p>
<li>Replacement of GNU
<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=bc">bc(1)</a>,
<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=dc">dc(1)</a>,
<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=nm">nm(1)</a> and
<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=size">size(1)</a>
commands with BSD licensed equivalents.
<p>
<li>A large number of bug fixes, changes, and optimizations to our packet filter
<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=pf">pf(4)</a>
including:
<ul>
<li>Atomic commits of ruleset changes (reduce the chance of ending up in an
inconsistent state).
<li>A 30 percent reduction in the size of state table entries.
<li>Source-tracking (limit number of clients and states per client).
<li>Sticky-address (the flexibility of round-robin with the benefits of
source-hash).
<li>Invert the specific/general socket match order when redirecting to
localhost (Prevents the potential security problem of remote connections
being identified as local).
<li>Significant improvements to interface handling.
</ul>
<p>
<li>New tools for high availability and load balancing:
<ul>
<li>CARP (the Common Address Redundancy Protocol)
<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=carp">carp(4)</a>
allows multiple machines to share responsibility for a given IP address or
addresses. If the owner of the address fails, another member of the group
will take over for it. A discussion of the history of CARP can be found
<a href="http://www.openbsd.org/lyrics.html">here</a>.
<li>Additions to the
<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=pfsync">pfsync(4)</a>
interface allow it to synchronise state table entries between two or more
firewalls which are operating in parallel, allowing stateful connections
to cross any of the firewalls regardless of where the state was initially
created.
</ul>
<p>
<li> New functionality:
<ul>
<li>New ptm device (see <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=pty&sektion=4">pty(4)</a>)
that allows non-privileged processes to allocate a properly-permissioned pty. No more setuid(root)
<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=xterm&sektion=1">xterm(1)</a>!
<li>The <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=closefrom&sektion=2">closefrom(2)</a>
system call has been added.
<li>TCP MD5 signatures (used by <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=nc&sektion=1">nc(1)</a>
and <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=bgpd&sektion=8">bgpd(8)</a>).
<li>i386 and amd64 <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=pxeboot&sektion=8&arch=i386">pxeboot(8)</a>.
<li>The i386 8GB boot loader limitation has been removed.
<li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=spamd&sektion=8">spamd(8)</a>
gains <a href="http://projects.puremagic.com/greylisting/">greylisting</a> support.
<li>Interface 'cloning,' accessed by
<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=ifconfig&sektion=8">ifconfig(8)</a>
commands <em>create</em> and <em>destroy</em>. E.g. `ifconfig vlan100 create'.
<li>The MAKEDEV(8) manual pages are now generated.
<li>Complete rewrite of package tools in perl.
<li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=syslogd&sektion=8">syslogd(8)</a>
now supports logging to memory buffers, to be read using
<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=syslogc&sektion=8">syslogc(8)</a>.
This is useful for diskless devices.
<li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=ipsec&sektion=4">IPsec</a> ESP in UDP encapsulation
</ul>
<p>
<li> New Privilege Separation Functionality:
<ul>
<li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=isakmpd&sektion=8">isakmpd(8)</a>
<li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=named&sektion=8">named(8)</a>
<li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=pflogd&sektion=8">pflogd(8)</a>
<li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=tcpdump&sektion=8">tcpdump(8)</a>
</ul>
<p>
<li> New tools:
<ul>
<li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=sensorsd&sektion=8">sensorsd(8)</a>, monitoring hardware sensors

<h3><font color="#0000e0">How to install</font></h3>
<p>
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.
<p>
<hr>
Please refer to the following files on the three CDROMs or ftp mirror for
extensive details on how to install OpenBSD 3.5 on your machine:
<p>
<ul>
<li>CD1:3.5/i386/INSTALL.i386
<li>CD1:3.5/vax/INSTALL.vax

<p>
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>CD1:3.5/i386/floppy35.fs</i> to a floppy and boot via the floppy drive.
<p>
Use <i>CD1:3.5/i386/floppyB35.fs</i> instead for greater scsi controller
support, or <i>CD1:3.5/i386/floppyC35.fs</i> for better laptop support.
<p>
If you are planning on dual booting OpenBSD with another OS, you will need to
read the included INSTALL.i386 document.
<p>
To make a boot floppy under MS-DOS, use the "rawrite" utility located
at <i>CD:/3.5/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">FAQ4.1</a>.
</ul>
<p>
<h3><font color="#e00000">OpenBSD/macppc:</font></h3>
<ul>
Put the 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
/3.5/macppc/bsd.rd</i>
</ul>
<p>
<h3><font color="#e00000">OpenBSD/amd64:</font></h3>
<ul>
[write a chunk here]
</ul>
<p>
<h3><font color="#e00000">OpenBSD/vax:</font></h3>
<ul>
Boot over the network via mopbooting as described in INSTALL.vax.
</ul>
<p>
<h3><font color="#e00000">OpenBSD/sparc:</font></h3>
<ul>
The 3.5 release of OpenBSD/sparc is located on CD3. To boot off of this CD you
can use one of the two commands listed below, depending on the version of your
ROM.
<ul><pre>
> <strong>boot cdrom 3.5/sparc/bsd.rd</strong>
or
> <strong>boot sd(0,6,0)3.5/sparc/bsd.rd</strong>
</pre></ul>
<p>
If your sparc does not have a CD drive, you can alternatively boot from floppy.
To do so you need to write "CD3:3.5/sparc/floppy35.fs" to a floppy.
For more information see <a href="faq/faq4.html#MkFlop">FAQ4.1</a>. To boot from
the floppy use one of the two commands listed below, depending on the version of
your ROM.
<ul><pre>
> <strong>boot floppy</strong>
or
> <strong>boot 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 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/sparc64:</font></h3>
<ul>
Put the 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>CD3:3.5/sparc64/floppy35.fs</i> to a floppy and boot it with <i>boot
floppy</i>.<br>
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>CD3:3.5/sparc64/miniroot35.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:3.5/alpha/floppy35.fs</i> or
<i>FTP:3.5/alpha/floppyB35.fs</i> (depending on your machine) to a diskette and
enter <i>boot dva0</i>. Refer to INSTALL.alpha for more details.
<p>
Make sure you use a properly formatted floppy with NO BAD BLOCKS or your install
will most likely fail.
</ul>
<p>
<h3><font color="#e00000">OpenBSD/hp300:</font></h3>
<ul>
<p>
Boot over the network by following the instructions in INSTALL.hp300.
</ul>
<p>
<h3><font color="#e00000">OpenBSD/hppa:</font></h3>
<ul>
<p>
Boot over the network by following the instructions in INSTALL.hppa or the
<a href="hppa.html#netboot">hppa platform page</a>.
</ul>
<p>
<h3><font color="#e00000">OpenBSD/mac68k:</font></h3>
<ul>
<p>
Boot MacOS as normal and partition your disk with the appropriate A/UX
configurations. Then, extract the Macside utilities from
<i>FTP:3.5/mac68k/utils</i> onto your hard disk. Run Mkfs to create your
filesystems on the A/UX partitions you just made. Then, use the
"BSD/Mac68k Installer" to copy all the sets in <i>FTP:3.5/mac68k/</i> onto your
partitions. Finally, you will be ready to configure the "BSD/Mac68k
Booter" with the location of your kernel and boot the system.
</ul>
<p>
<h3><font color="#e00000">OpenBSD/mvme68k:</font></h3>
<ul>
<p>
You can create a bootable installation tape or boot over the network.<br>
The network boot requires a MVME68K BUG version that supports the <i>NIOT</i>
and <i>NBO</i> debugger commands. Follow the instructions in INSTALL.mvme68k
for more details.
</ul>
<p>
<h3><font color="#e00000">OpenBSD/mvme88k:</font></h3>
<ul>
<p>
You can create a bootable installation tape or boot over the network.<br>
The network boot requires a MVME88K BUG version that supports the <i>NIOT</i>
and <i>NBO</i> debugger commands. Follow the instructions in INSTALL.mvme88k
for more 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="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="ports.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&format=html">
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 anoncvsserver.openbsd.org:/cvs update -Pd -rOPENBSD_3_5</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 3.5 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 ports@openbsd.org is a good
place to know.
