RELEASE NOTES FreeBSD Release 3.4-RELEASE Welcome to 3.4-RELEASE, a full follow-on to 3.3-RELEASE released 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 http://www.freebsd.org/send-pr.html). For information about FreeBSD and the layout of the 3.4-RELEASE directory (especially if you're installing from floppies!), see ABOUT.TXT. For installation instructions, see the INSTALL.TXT and HARDWARE.TXT files. Table of contents: ------------------ 1.

What's new since 3.3-RELEASE --------------------------------- 1.1. KERNEL CHANGES ------------------- 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). 1.2. SECURITY CHANGES --------------------- 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. 1.3. USERLAND CHANGES --------------------- 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. 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. 2.1.

FreeBSD currently does NOT support IBM's microchannel (MCA) bus. 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 `ftp.freebsd.org' - 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 freebsd-admin@FreeBSD.org 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 `ftpmail@ftpmail.vix.com' - 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 orders@cdrom.com or http://www.cdrom.com. Their current catalog can be obtained via ftp from: ftp://ftp.cdrom.com/cdrom/catalog 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 obligation. 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 //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 http://www.freebsd.org/send-pr.html. 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: freebsd-bugs@FreeBSD.org 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: freebsd-questions@FreeBSD.org 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: freebsd-hackers@FreeBSD.org 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: freebsd-announce@FreeBSD.org All of the mailing lists can be freely joined by anyone wishing to do so. Send mail to MajorDomo@FreeBSD.org 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! 6. Acknowledgments ------------------- FreeBSD represents the cumulative work of many dozens, if not hundreds, of individuals from around the world who have worked very hard to bring you this release. For a complete list of FreeBSD project staffers, please see: http://www.freebsd.org/handbook/staff.html or, if you've loaded the doc distribution: file:/usr/share/doc/handbook/staff.html Special mention to: The donors listed at http://www.freebsd.org/handbook/donors.html And to the many thousands of FreeBSD users and testers all over the world, without whom this release simply would not have been possible. We sincerely hope you enjoy this release of FreeBSD! The FreeBSD Project # $FreeBSD: src/release/texts/alpha/RELNOTES.TXT,v 1.1.2.17 1999/12/12 21:06:54 jkh Exp $
