information on how to obtain FreeBSD, a listing of various ways to contact the FreeBSD
Project, and pointers to some other sources of information.</p>

<div class="SECT1">
<hr />
<h2 class="SECT1"><a id="AEN16" name="AEN16">1 Introduction</a></h2>
<p>This distribution is a release of FreeBSD 4.11-RELEASE, the latest point along the
4-STABLE branch.</p>
<div class="SECT2">
<hr />
<h3 class="SECT2"><a id="AEN19" name="AEN19">1.1 About FreeBSD</a></h3>
<p>FreeBSD is an operating system based on 4.4 BSD Lite for Intel, AMD, Cyrix or NexGen
``x86'' based PC hardware and Compaq (formerly DEC) Alpha computers. Versions for the
IA64, PowerPC, and Sparc64 architectures are currently under development as well. FreeBSD
works with a wide variety of peripherals and configurations and can be used for
everything from software development to games to Internet Service Provision.</p>
<p>This release of FreeBSD contains everything you need to run such a system, including
full source code for the kernel and all utilities in the base distribution. With the
source distribution installed, you can literally recompile the entire system from scratch
with one command, making it ideal for students, researchers, or users who simply want to
see how it all works.</p>
<p>A large collection of third-party ported software (the ``Ports Collection'') is also
provided to make it easy to obtain and install all your favorite traditional UNIX
utilities for FreeBSD. Each ``port'' consists of a set of scripts to retrieve, configure,
build, and install a piece of software, with a single command. Over 11,800 ports, from
editors to programming languages to graphical applications, make FreeBSD a powerful and
comprehensive operating environment that extends far beyond what's provided by many
commercial versions of UNIX. Most ports are also available as pre-compiled ``packages'',
which can be quickly installed from the installation program.</p>
</div>
<div class="SECT2">
<hr />
<h3 class="SECT2"><a id="AEN28" name="AEN28">1.2 Target Audience</a></h3>
<p>This release of FreeBSD is suitable for all users. It has undergone a period of
testing and quality assurance checking to ensure the highest reliability and
dependability.</p>
</div>
</div>
<div class="SECT1">
<hr />
<h2 class="SECT1"><a id="AEN31" name="AEN31">2 Obtaining FreeBSD</a></h2>
<p>FreeBSD may be obtained in a variety of ways. This section focuses on those ways that
are primarily useful for obtaining a complete FreeBSD distribution, rather than updating
an existing installation.</p>
<div class="SECT2">
<hr />
<h3 class="SECT2"><a id="AEN34" name="AEN34">2.1 CDROM and DVD</a></h3>
<p>FreeBSD -RELEASE distributions may be ordered on CDROM or DVD from several publishers.
This is frequently the most convenient way to obtain FreeBSD for new installations, as it
provides a convenient way to quickly reinstall the system if necessary. Some
distributions include some of the optional, precompiled ``packages'' from the FreeBSD
Ports Collection.</p>
<p>A list of the CDROM and DVD publishers known to the project are listed in the <a
href="http://www.FreeBSD.org/doc/en_US.ISO8859-1/books/handbook/mirrors.html"
target="_top">``Obtaining FreeBSD''</a> appendix to the Handbook.</p>
</div>
<div class="SECT2">
<hr />
<h3 class="SECT2"><a id="AEN41" name="AEN41">2.2 FTP</a></h3>
<p>You can use FTP to retrieve FreeBSD and any or all of its optional packages from <a
href="ftp://ftp.FreeBSD.org/" target="_top">ftp://ftp.FreeBSD.org/</a>, which is the
official FreeBSD release site, or any of its ``mirrors''.</p>
<p>Lists of locations that mirror FreeBSD can be found in the <a
href="http://www.FreeBSD.org/doc/en_US.ISO8859-1/books/handbook/mirrors-ftp.html"
target="_top">FTP Sites</a> section of the Handbook, or on the <a
href="http://www.freebsdmirrors.org/" target="_top">http://www.freebsdmirrors.org/</a>
Web pages. Finding a close (in networking terms) mirror from which to download the
distribution is highly recommended.</p>
<p>Additional mirror sites are always welcome. Contact <code class="EMAIL">&#60;<a
href="mailto:freebsd-admin@FreeBSD.org">freebsd-admin@FreeBSD.org</a>&#62;</code> for
more details on becoming an official mirror site.</p>
<p>Mirrors generally contain the floppy disk images necessary to begin an installation,
as well as the distribution files needed for the install process itself. Many mirrors
also contain the ISO images necessary to create a CDROM of a FreeBSD release.</p>

Project</a></h2>
<div class="SECT2">
<h3 class="SECT2"><a id="AEN54" name="AEN54">3.1 Email and Mailing Lists</a></h3>
<p>For any questions or general technical support issues, please send mail to the <a
href="http://lists.FreeBSD.org/mailman/listinfo/freebsd-questions" target="_top">FreeBSD
general questions mailing list</a>.</p>
<p>If you are tracking the -STABLE development efforts, you <span class="emphasis"><i
class="EMPHASIS">must</i></span> join the <a
href="http://lists.FreeBSD.org/mailman/listinfo/freebsd-stable"
target="_top">FreeBSD-STABLE mailing list</a>, in order to keep abreast of recent
developments and changes that may affect the way you use and maintain the system.</p>
<p>Being a largely-volunteer effort, the FreeBSD Project is always happy to have extra
hands willing to help--there are already far more desired enhancements than there is time
to implement them. To contact the developers on technical matters, or with offers of
help, please send mail to the <a
href="http://lists.FreeBSD.org/mailman/listinfo/freebsd-hackers" target="_top">FreeBSD
technical discussions mailing list</a>.</p>
<p>Please note that these mailing lists can experience <span class="emphasis"><i
class="EMPHASIS">significant</i></span> amounts of traffic. If you have slow or expensive
mail access, or are only interested in keeping up with major FreeBSD events, you may find
it preferable to subscribe instead to the <a
href="http://lists.FreeBSD.org/mailman/listinfo/freebsd-announce" target="_top">FreeBSD
announcements mailing list</a>.</p>
<p>All of the mailing lists can be freely joined by anyone wishing to do so. Visit <a
href="http://www.FreeBSD.org/mailman/listinfo" target="_top">FreeBSD Mailman Info
Page</a>. This will give you more information on joining the various lists, accessing
archives, etc. There are a number of mailing lists targeted at special interest groups
not mentioned here; more information can be obtained either through majordomo or the <a
href="http://www.FreeBSD.org/support.html#mailing-list" target="_top">mailing lists
section</a> of the FreeBSD Web site.</p>
<div class="IMPORTANT">
<blockquote class="IMPORTANT">
<p><b>Important:</b> Do <span class="emphasis"><i class="EMPHASIS">not</i></span> send
email to the lists asking to be subscribed. Use the <code class="EMAIL">&#60;<a

<h3 class="SECT2"><a id="AEN73" name="AEN73">3.2 Submitting Problem Reports</a></h3>
<p>Suggestions, bug reports and contributions of code are always valued--please do not
hesitate to report any problems you may find. Bug reports with attached fixes are of
course even more welcome.</p>
<p>The preferred method to submit bug reports from a machine with Internet mail
connectivity is to use the <a
href="http://www.FreeBSD.org/cgi/man.cgi?query=send-pr&sektion=1&manpath=FreeBSD+4.11-RELEASE">
<span class="CITEREFENTRY"><span class="REFENTRYTITLE">send-pr</span>(1)</span></a>
command or use the Web form at <a href="http://www.FreeBSD.org/send-pr.html"
target="_top">http://www.FreeBSD.org/send-pr.html</a>. ``Problem Reports'' (PRs)
submitted in this way will be filed and their progress tracked; the FreeBSD developers
will do their best to respond to all reported bugs as soon as possible. <a
href="http://www.FreeBSD.org/cgi/query-pr-summary.cgi" target="_top">A list of all active
PRs</a> is available on the FreeBSD Web site; this list is useful to see what potential
problems other users have encountered.</p>
<p>Note that <a

<span class="CITEREFENTRY"><span class="REFENTRYTITLE">send-pr</span>(1)</span></a>
itself is a shell script that should be easy to move even onto a non-FreeBSD system.
Using this interface is highly preferred. If, for some reason, you are unable to use <a

<span class="CITEREFENTRY"><span class="REFENTRYTITLE">send-pr</span>(1)</span></a> to
submit a bug report, you can try to send it to the <a

installing it, to learn about any ``late-breaking news'' or post-release problems. The
errata file accompanying each release (most likely right next to this file) is already
out of date by definition, but other copies are kept updated on the Internet and should

<h3 class="SECT2"><a id="AEN134" name="AEN134">4.2 Manual Pages</a></h3>
<p>As with almost all UNIX-like operating systems, FreeBSD comes with a set of on-line
manual pages, accessed through the <a
href="http://www.FreeBSD.org/cgi/man.cgi?query=man&sektion=1&manpath=FreeBSD+4.11-RELEASE">
<span class="CITEREFENTRY"><span class="REFENTRYTITLE">man</span>(1)</span></a> command
or through the <a href="http://www.FreeBSD.org/cgi/man.cgi" target="_top">hypertext
manual pages gateway</a> on the FreeBSD Web site. In general, the manual pages provide
information on the different commands and APIs available to the FreeBSD user.</p>
<p>In some cases, manual pages are written to give information on particular topics.
Notable examples of such manual pages are <a

<h4 class="SECT3"><a id="NET-PROTO" name="NET-PROTO">2.2.3 Network Protocols</a></h4>
<p>The random ephemeral port allocation, which come from OpenBSD has been implemented.
This is enabled by default and can be disabled using the <var
class="VARNAME">net.inet.ip.portrange.randomized</var> sysctl. Note that the
randomization can lead to extremely fast port reuse at high connection rates, which is
causing problems for some users. To retain the security advantage of random ports and
ensure correct operation, it is disabled during periods of high connection rates. More
specifically, when the connection rate exceeds the value of the <var
class="VARNAME">net.inet.ip.portrange.randomcps</var> sysctl (<var
class="LITERAL">10</var> by default), the randomization will be disabled for seconds
specified in the <var class="VARNAME">net.inet.ip.portrange.randomtime</var> sysctl (<var
class="LITERAL">45</var> by default).</p>
<p><a
href="http://www.FreeBSD.org/cgi/man.cgi?query=ipfw&sektion=4&manpath=FreeBSD+4.11-RELEASE">
<span class="CITEREFENTRY"><span class="REFENTRYTITLE">ipfw</span>(4)</span></a> now

sets.</p>

<span class="CITEREFENTRY"><span class="REFENTRYTITLE">ipnat</span>(8)</span></a> now
allows redirect rules to work for non-TCP/UDP packets.</p>
<p>The <var class="LITERAL">RST</var> handling of the FreeBSD TCP stack has been improved
to make reset attacks as difficult as possible while maintaining compatibility with the
widest range of TCP stacks. The algorithm is as follows. For connections in the <var
class="LITERAL">ESTABLISHED</var> state, only resets with sequence numbers exactly
matching <var class="VARNAME">last_ack_sent</var> will cause a reset, all other segments
will be silently dropped. For connections in all other states, a reset anywhere in the
window will cause the connection to be reset. All other segments will be silently
dropped. Note that this breaks the RFC 793 specification and you can still disable this
and use the conventional behavior by setting a new sysctl <var
class="VARNAME">net.inet.tcp.insecure_rst</var> to <var class="LITERAL">1</var>.</p>

<h2 class="SECT1"><a id="UPGRADE" name="UPGRADE">3 Upgrading from previous releases of
FreeBSD</a></h2>
<p>If you're upgrading from a previous release of FreeBSD, you generally will have three
options:</p>
<ul>
<li>
<p>Using the binary upgrade option of <a
href="http://www.FreeBSD.org/cgi/man.cgi?query=sysinstall&sektion=8&manpath=FreeBSD+4.11-RELEASE">
<span class="CITEREFENTRY"><span class="REFENTRYTITLE">sysinstall</span>(8)</span></a>.
This option is perhaps the quickest, although it presumes that your installation of
FreeBSD uses no special compilation options.</p>
</li>
<li>
<p>Performing a complete reinstall of FreeBSD. Technically, this is not an upgrading
method, and in any case is usually less convenient than a binary upgrade, in that it
requires you to manually backup and restore the contents of <tt
class="FILENAME">/etc</tt>. However, it may be useful in cases where you want (or need)
to change the partitioning of your disks.</p>
</li>
<li>
<p>From source code in <tt class="FILENAME">/usr/src</tt>. This route is more flexible,
but requires more disk space, time, and technical expertise. More information can be
found in the <a
href="http://www.FreeBSD.org/doc/en_US.ISO8859-1/books/handbook/makeworld.html"
target="_top">``Using <tt class="COMMAND">make world</tt>''</a> section of the <a
href="http://www.FreeBSD.org/doc/en_US.ISO8859-1/books/handbook/" target="_top">FreeBSD
Handbook</a>. Upgrading from very old versions of FreeBSD may be problematic; in cases
like this, it is usually more effective to perform a binary upgrade or a complete
reinstall.</p>
</li>
</ul>
<br />
<br />
<p>Please read the <tt class="FILENAME">INSTALL.TXT</tt> file for more information,
preferably <span class="emphasis"><i class="EMPHASIS">before</i></span> beginning an
upgrade. If you are upgrading from source, please be sure to read <tt
class="FILENAME">/usr/src/UPDATING</tt> as well.</p>
<p>Finally, if you want to use one of various means to track the -STABLE or -CURRENT
branches of FreeBSD, please be sure to consult the <a
href="http://www.FreeBSD.org/doc/en_US.ISO8859-1/books/handbook/current-stable.html"
target="_top">``-CURRENT vs. -STABLE''</a> section of the <a
href="http://www.FreeBSD.org/doc/en_US.ISO8859-1/books/handbook/" target="_top">FreeBSD
Handbook</a>.</p>
<div class="IMPORTANT">
<blockquote class="IMPORTANT">
<p><b>Important:</b> Upgrading FreeBSD should, of course, only be attempted after backing
up <span class="emphasis"><i class="EMPHASIS">all</i></span> data and configuration

<p>The random ephemeral port allocation, which come from OpenBSD has been implemented.
This is enabled by default and can be disabled using the <var
class="VARNAME">net.inet.ip.portrange.randomized</var> sysctl. Note that the
randomization can lead to extremely fast port reuse at high connection rates, which is
causing problems for some users. To retain the security advantage of random ports and
ensure correct operation, it is disabled during periods of high connection rates. More
specifically, when the connection rate exceeds the value of the <var
class="VARNAME">net.inet.ip.portrange.randomcps</var> sysctl (<var
class="LITERAL">10</var> by default), the randomization will be disabled for seconds
specified in the <var class="VARNAME">net.inet.ip.portrange.randomtime</var> sysctl (<var
class="LITERAL">45</var> by default).</p>
<p><a

<span class="CITEREFENTRY"><span class="REFENTRYTITLE">ipfw</span>(4)</span></a> now

sets.</p>

<span class="CITEREFENTRY"><span class="REFENTRYTITLE">ipnat</span>(8)</span></a> now
allows redirect rules to work for non-TCP/UDP packets.</p>
<p>The <var class="LITERAL">RST</var> handling of the FreeBSD TCP stack has been improved
to make reset attacks as difficult as possible while maintaining compatibility with the
widest range of TCP stacks. The algorithm is as follows. For connections in the <var
class="LITERAL">ESTABLISHED</var> state, only resets with sequence numbers exactly
matching <var class="VARNAME">last_ack_sent</var> will cause a reset, all other segments
will be silently dropped. For connections in all other states, a reset anywhere in the
window will cause the connection to be reset. All other segments will be silently
dropped. Note that this breaks the RFC 793 specification and you can still disable this
and use the conventional behavior by setting a new sysctl <var
class="VARNAME">net.inet.tcp.insecure_rst</var> to <var class="LITERAL">1</var>.</p>

<h2 class="SECT1"><a id="UPGRADE" name="UPGRADE">3 Upgrading from previous releases of
FreeBSD</a></h2>
<p>If you're upgrading from a previous release of FreeBSD, you generally will have three
options:</p>
<ul>
<li>
<p>Using the binary upgrade option of <a
href="http://www.FreeBSD.org/cgi/man.cgi?query=sysinstall&sektion=8&manpath=FreeBSD+4.11-RELEASE">
<span class="CITEREFENTRY"><span class="REFENTRYTITLE">sysinstall</span>(8)</span></a>.
This option is perhaps the quickest, although it presumes that your installation of
FreeBSD uses no special compilation options.</p>
</li>
<li>
<p>Performing a complete reinstall of FreeBSD. Technically, this is not an upgrading
method, and in any case is usually less convenient than a binary upgrade, in that it
requires you to manually backup and restore the contents of <tt
class="FILENAME">/etc</tt>. However, it may be useful in cases where you want (or need)
to change the partitioning of your disks.</p>
</li>
<li>
<p>From source code in <tt class="FILENAME">/usr/src</tt>. This route is more flexible,
but requires more disk space, time, and technical expertise. More information can be
found in the <a
href="http://www.FreeBSD.org/doc/en_US.ISO8859-1/books/handbook/makeworld.html"
target="_top">``Using <tt class="COMMAND">make world</tt>''</a> section of the <a
href="http://www.FreeBSD.org/doc/en_US.ISO8859-1/books/handbook/" target="_top">FreeBSD
Handbook</a>. Upgrading from very old versions of FreeBSD may be problematic; in cases
like this, it is usually more effective to perform a binary upgrade or a complete
reinstall.</p>
</li>
</ul>
<br />
<br />
<p>Please read the <tt class="FILENAME">INSTALL.TXT</tt> file for more information,
preferably <span class="emphasis"><i class="EMPHASIS">before</i></span> beginning an
upgrade. If you are upgrading from source, please be sure to read <tt
class="FILENAME">/usr/src/UPDATING</tt> as well.</p>
<p>Finally, if you want to use one of various means to track the -STABLE or -CURRENT
branches of FreeBSD, please be sure to consult the <a
href="http://www.FreeBSD.org/doc/en_US.ISO8859-1/books/handbook/current-stable.html"
target="_top">``-CURRENT vs. -STABLE''</a> section of the <a
href="http://www.FreeBSD.org/doc/en_US.ISO8859-1/books/handbook/" target="_top">FreeBSD
Handbook</a>.</p>
<div class="IMPORTANT">

<p><b>Important:</b> Upgrading FreeBSD should, of course, only be attempted after backing
