FreeBSD 3.4 Release Notes

                  RELEASE NOTES - FREEBSD 3.4-RELEASE

Welcome to 3.4-RELEASE, a full follow-on to 3.3-RELEASE which was
shipped in October 1999.  In the months since 3.3 was released, many
bug fixes and general enhancements have been made to the system.  Please
see relevant details below.

Any installation failures or crashes should be reported by using the
send-pr command (those preferring a WEB based interface can also see

1. What's new since 3.3-RELEASE


Support for Adaptec 152x/151x/AIC-6360 SCSI controllers is back.

netgraph(4) has been added.  Netgraph provides a uniform and modular system
for the implementation of kernel objects which perform various networking
functions.  To enable it, ``options NETGRAPH'' must be added to the kernel.

i4b(4) has been upgraded to version 00.83.00, providing increased robustness
and stability, and supporting many new cards (Asuscom ISDNlink 128K,
AVM Fritz!Card PCI, AVM Fritz!Card PnP, ELSA PCC-16, ITK ix1 micro V.3,
Siemens I-Surf 2.0).

RAID-5 support has been added to vinum(8).

Driver support for the Intel PIIX4 and AcerLabs M15x3 power management
controllers has been added.


Support has been added for blocking incoming ICMP redirects, outgoing RST
frames and incoming SYN|FIN frames in order to lessen or nullify the
impact of certain kinds of DoS attacks.

Support has been added for forwarding IP datagrams without inspecting or
decreasing the TTL in order to make gateways and firewalls less visible
and therefore less exposed to attacks.

New networking security features include the ability to drop TCP packets with
SYN+FIN (NOTE: this breaks rfc1644 extensions (T/TCP)), restrict emission of
RST, ignore incoming ICMP REDIRECT messages, and also set to log incoming
ICMP REDIRECT messages.  See rc.conf(5) for details on how to utilize these
new features.


Inetd has gained built-in support for ident and has a workaround
for accidently blocking while accepting.

ppp(8) now supports PPPoE (PPP over Ethernet) compliments of the pppoe
netgraph node.  It also supports PPP over ISDN, including standard ISDN
link bonding.  ppp(8) now uses the -nat command line argument and the ``nat''
command to control network address translation.  The old [-]alias command
still works, but produces a warning and will soon be removed.  Additionally,
ppp(8) now loads the tun module as required, allows a tun unit specification
on the command line, supports a -foreground command line option, allows
fast-queue configuration, provides a functional ``set autoload'' command
(for on-demand multi-link ppp), allows GRE packet filtering and has had
many bugs fixed.

There's a new pppoed daemon for servicing PPP over Ethernet requests.
Refer to rc.conf(5) and pppoed(8) for details.

2. Supported Configurations
FreeBSD currently runs on a wide variety of ISA, VLB, EISA and PCI bus
based PC's, ranging from 386sx to Pentium class machines (though the
386sx is not recommended).  Support for generic IDE or ESDI drive
configurations, various SCSI controller, network and serial cards is
also provided.

What follows is a list of all peripherals currently known to work with
FreeBSD.  Other configurations may also work, we have simply not as yet
received confirmation of this.

3. Obtaining FreeBSD

You may obtain FreeBSD in a variety of ways:

3.1. FTP/Mail

You can ftp FreeBSD and any or all of its optional packages from
`' - the official FreeBSD release site.

For other locations that mirror the FreeBSD software see the file
MIRROR.SITES.  Please ftp the distribution from the site closest (in
networking terms) to you.  Additional mirror sites are always welcome!
Contact for more details if you'd like to
become an official mirror site.

If you do not have access to the Internet and electronic mail is your
only recourse, then you may still fetch the files by sending mail to
`' - putting the keyword "help" in your message
to get more information on how to fetch files using this mechanism.
Please do note, however, that this will end up sending many *tens of
megabytes* through the mail and should only be employed as an absolute
LAST resort!

3.2. CDROM

FreeBSD 3.4-RELEASE CDs may be ordered on CDROM from:

        Walnut Creek CDROM
        4041 Pike Lane, Suite F
        Concord CA  94520
        1-800-786-9907, +1-925-674-0783, +1-925-674-0821 (FAX)

Or via the Internet from or
Their current catalog can be obtained via ftp from:

Cost per -RELEASE CD is $39.95 or $24.95 with a FreeBSD subscription.
FreeBSD SNAPshot CDs, when available, are $39.95 or $14.95 with a
FreeBSD-SNAP subscription (-RELEASE and -SNAP subscriptions are entirely
separate).  With a subscription, you will automatically receive updates as
they are released.  Your credit card will be billed when each disk is
shipped and you may cancel your subscription at any time without further

Shipping (per order not per disc) is $5 in the US, Canada or Mexico
and $9.00 overseas.  They accept Visa, Mastercard, Discover, American
Express or checks in U.S. Dollars and ship COD within the United
States.  California residents please add 8.25% sales tax.

Should you be dissatisfied for any reason, the CD comes with an
unconditional return policy.

4. Upgrading from previous releases of FreeBSD

If you're upgrading from a previous release of FreeBSD, most likely
it's 2.2.x or 2.1.x (in some lesser number of cases) and some of the
following issues may affect you, depending of course on your chosen
method of upgrading.  There are two popular ways of upgrading
FreeBSD distributions:

        o Using sources, via /usr/src
        o Using sysinstall's (binary) upgrade option.

In the case of using sources, there are simply two targets you need to
be aware of: The standard ``upgrade'' target, which will upgrade a 2.x
or 3.0 system to 3.4 and the ``world'' target, which will take an
already upgraded system and keep it in sync with whatever changes have
happened since the initial upgrade.

In the case of using the binary upgrade option, the system will go
straight to 3.4/ELF but also populate the /<basepath>/lib/aout
directories for backwards compatibility with older binaries.

In either case, going to ELF will mean that you'll have somewhat
smaller binaries and access to a lot more compiler goodies which have
been already been ported to other ELF environments (our older and
somewhat crufty a.out format being largely unsupported by most other
software projects).  Those who wish to retain access to the older
a.out dynamic executables should be sure and install the compat22
distribution. Notice that the a.out libraries won't be accessible
until the system is rebooted, which may cause trouble with certain
a.out packages.

Also, do not use install disks or sysinstall from previous versions,
as version 3.1 introduced a new bootstrapping procedure, requiring
new boot blocks to be installed (because of elf kernels), and version
3.2 has further modifications to the bootstrapping procedure.

[ other important upgrading notes should go here]

5. Reporting problems, making suggestions, submitting code.
Your suggestions, bug reports and contributions of code are always
valued - please do not hesitate to report any problems you may find
(preferably with a fix attached, if you can!).

The preferred method to submit bug reports from a machine with
Internet mail connectivity is to use the send-pr command or use the CGI
script at  Bug reports
will be dutifully filed by our faithful bugfiler program and you can
be sure that we'll do our best to respond to all reported bugs as soon
as possible.  Bugs filed in this way are also visible on our WEB site
in the support section and are therefore valuable both as bug reports
and as "signposts" for other users concerning potential problems to
watch out for.

If, for some reason, you are unable to use the send-pr command to
submit a bug report, you can try to send it to:


Note that send-pr itself is a shell script that should be easy to move
even onto a totally different system.  We much prefer if you could use
this interface, since it make it easier to keep track of the problem
reports.  However, before submitting, please try to make sure whether
the problem might have already been fixed since.

Otherwise, for any questions or tech support issues, please send mail to:


Additionally, being a volunteer effort, we are always happy to have
extra hands willing to help - there are already far more desired
enhancements than we'll ever be able to manage by ourselves!  To
contact us on technical matters, or with offers of help, please send
mail to:


Please note that these mailing lists can experience *significant*
amounts of traffic and if you have slow or expensive mail access and
are only interested in keeping up with significant FreeBSD events, you
may find it preferable to subscribe instead to:


All of the mailing lists can be freely joined by anyone wishing
to do so.  Send mail to and include the keyword
`help' on a line by itself somewhere in the body of the message.  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, so send mail to majordomo
and ask about them!
