199: and
200: <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=sshd&sektion=8">sshd(8)</a>:
201: Added support for AES-GCM authenticated encryption in SSH protocol 2.
202: The new cipher is available as "aes128-gcm@openssh.com" and
203: "aes256-gcm@openssh.com". It uses an identical packet format to the
204: AES-GCM mode specified in RFC 5647, but uses simpler and different
205: selection rules during key exchange.
206: <li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=ssh&sektion=1">ssh(1)</a>
207: and
208: <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=sshd&sektion=8">sshd(8)</a>:
209: Added support for encrypt-then-mac (EtM) MAC modes for SSH protocol 2.
210: These modes alter the packet format and compute the MAC over the
211: packet length and encrypted packet rather than over the plaintext
212: data. These modes are considered more secure and are used by default
213: when available.
214: <li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=ssh&sektion=1">ssh(1)</a>
215: and

218: "umac-128-etm@openssh.com". The latter being an encrypt-then-mac mode.
219: <li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=sshd&sektion=8">sshd(8)</a>:
220: Added support for multiple required authentication in SSH protocol 2
221: via an <tt>AuthenticationMethods</tt> option. This option lists one
222: or more comma-separated lists of authentication method names.
223: Successful completion of all the methods in any list is required for
224: authentication to complete. This allows, for example, requiring a
225: user having to authenticate via public key or GSSAPI before they are
226: offered password authentication.
227: <li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=sshd&sektion=8">sshd(8)</a>
228: and

230: Added support for Key Revocation Lists (KRLs), a compact binary
231: format to represent lists of revoked keys and certificates that take
232: as little as one bit per certificate when revoking by serial number.
233: KRLs may be generated using
234: <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=ssh-keygen&sektion=1">ssh-keygen(1)</a>
235: and are loaded into

1.1 sthen 316: the package build process
317: <ul>

319: that dpb consumes much less cpu on busy boxes, but there are lots of small
320: optimizations that amount to a large performance increase:
321: dpb can now build selected large ports using parallel make, and it
322: has a notion of affinity, so that ports failing on a cluster will be
1.29 sthen 323: preferentially restarted on the same machine.

439: Quick installer information for people familiar with OpenBSD, and the
440: use of the "disklabel -E" command. If you are at all confused when
441: installing OpenBSD, read the relevant INSTALL.* file as listed above!

443:
444: <h3><font color="#e00000">OpenBSD/i386:</font></h3>
445: <ul>
446: Play with your BIOS options to enable booting from a CD. The OpenBSD/i386
447: release is on CD1. If your BIOS does not support booting from CD, you will need
448: to create a boot floppy to install from. To create a boot floppy write
449: <i>CD1:5.3/i386/floppy53.fs</i> to a floppy and boot via the floppy drive.
450:
451: <p>
452: Use <i>CD1:5.3/i386/floppyB53.fs</i> instead for greater SCSI controller
453: support, or <i>CD1:5.3/i386/floppyC53.fs</i> for better laptop support.
454:
455: <p>
456: If you can't boot from a CD or a floppy disk,
457: you can install across the network using PXE as described in
458: the included INSTALL.i386 document.
459:
460: <p>
461: If you are planning on dual booting OpenBSD with another OS, you will need to
462: read INSTALL.i386.
463:
464: <p>
465: To make a boot floppy under MS-DOS, use the "rawrite" utility located
466: at <i>CD1:5.3/tools/rawrite.exe</i>. To make the boot floppy under a Unix OS,
467: use the
1.11 sthen 468: <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=dd&sektion=1">dd(1)</a>
1.1 sthen 469: utility. The following is an example usage of
1.11 sthen 470: <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=dd&sektion=1">dd(1)</a>,
1.1 sthen 471: where the device could be "floppy", "rfd0c", or

475: # <strong>dd if=<file> of=/dev/<device> bs=32k</strong>

477:

479: Make sure you use properly formatted perfect floppies with NO BAD BLOCKS or
480: your install will most likely fail. For more information on creating a boot
481: floppy and installing OpenBSD/i386 please refer to

489: Boot from the CD to begin the install - you may need to adjust
490: your BIOS options first.
491: If you can't boot from the CD, you can create a boot floppy to install from.
492: To do this, write <i>CD2:5.3/amd64/floppy53.fs</i> to a floppy, then
493: boot from the floppy drive.
494:

654: Boot from one of the provided install ISO images, using one of the two
655: commands listed below, depending on the version of your ROM.
656:
657: <ul><pre>
658: ok <strong>boot cdrom 5.3/sparc/bsd.rd</strong>

664: If your SPARC system does not have a CD drive, you can alternatively boot from floppy.
665: To do so you need to write <i>floppy53.fs</i> to a floppy.
666: For more information see <a href="faq/faq4.html#MkFlop">FAQ 4.3.2</a>.
667: To boot from the floppy use one of the two commands listed below,
668: depending on the version of your ROM.
669:
670: <ul><pre>
671: ok <strong>boot floppy</strong>
672: or
673: > <strong>b fd()</strong>
674: </pre></ul>
675:
676: <p>
677: Make sure you use a properly formatted floppy with NO BAD BLOCKS or your install
678: will most likely fail.
679:
680: <p>
681: If your SPARC system doesn't have a floppy drive nor a CD drive, you can either
682: setup a bootable tape, or install via network, as told in the
683: INSTALL.sparc file.

704: src.tar.gz contains a source archive starting at /usr/src. This file
705: contains everything you need except for the kernel sources, which are
706: in a separate archive. To extract:
707: <p>
708: <ul><pre>
709: # <strong>mkdir -p /usr/src</strong>
710: # <strong>cd /usr/src</strong>
711: # <strong>tar xvfz /tmp/src.tar.gz</strong>
712: </pre></ul>
713: <p>
714: sys.tar.gz contains a source archive starting at /usr/src/sys.
715: This file contains all the kernel sources you need to rebuild kernels.
716: To extract:
717: <p>
718: <ul><pre>
719: # <strong>mkdir -p /usr/src/sys</strong>
720: # <strong>cd /usr/src</strong>
721: # <strong>tar xvfz /tmp/sys.tar.gz</strong>
722: </pre></ul>
723: <p>
724: Both of these trees are a regular CVS checkout. Using these trees it
725: is possible to get a head-start on using the anoncvs servers as
726: described <a href="anoncvs.html">here</a>.
727: Using these files
728: results in a much faster initial CVS update than you could expect from
729: a fresh checkout of the full OpenBSD source tree.

747: A ports tree archive is also provided. To extract:
748: <p>
749: <ul><pre>
750: # <strong>cd /usr</strong>

752: # <strong>cd ports</strong>
753: </pre></ul>
754: <p>
755: The <i>ports/</i> subdirectory is a checkout of the OpenBSD ports tree. Go
756: read the <a href="faq/ports/index.html">ports</a> page
757: if you know nothing about ports
758: at this point. This text is not a manual of how to use ports.
759: Rather, it is a set of notes meant to kickstart the user on the
760: OpenBSD ports system.
761: <p>
762: The <i>ports/</i> directory represents a CVS (see the manpage for
1.11 sthen 763: <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=cvs&sektion=1&arch=i386">
1.1 sthen 764: cvs(1)</a> if
765: you aren't familiar with CVS) checkout of our ports. As with our complete
1.17 rpe 766: source tree, our ports tree is available via
767: <a href="anoncvs.html">AnonCVS</a>.
768: So, in order to keep current with it, you must make the <i>ports/</i> tree
1.1 sthen 769: available on a read-write medium and update the tree with a command
770: like:
771: <p>
772: <ul><pre>
773: # <strong>cd [portsdir]/; cvs -d anoncvs@server.openbsd.org:/cvs update -Pd -rOPENBSD_5_3</strong>
774: </pre></ul>
775: <p>
776: [Of course, you must replace the local directory and server name here
777: with the location of your ports collection and a nearby anoncvs
778: server.]
779: <p>
780: Note that most ports are available as packages through FTP. Updated
781: packages for the 5.3 release will be made available if problems arise.
782: <p>
783: If you're interested in seeing a port added, would like to help out, or just
784: would like to know more, the mailing list
785: <a href="mail.html">ports@openbsd.org</a> is a good place to know.
