267: </ul>
268: <p>
269:

1.3 deraadt 271: <ul>
272: <li>New features:
1.4 sobrado 273: <ul>
274: <li>Implement Elliptic Curve Cryptography modes for key exchange (ECDH)
275: and host/user keys (ECDSA) as specified by RFC5656. ECDH and ECDSA
276: offer better performance than plain DH and DSA at the same
277: equivalent symmetric key length, as well as much shorter keys.</li>
278: <li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=sftp&sektion=1">sftp(1)</a>

281: add a protocol extension to support a hard link operation. It is
282: available through the "ln" command in the client. The old "ln"
283: behaviour of creating a symlink is available using its "-s" option
284: or through the preexisting "symlink" command.</li>
285: <li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=scp&sektion=1">scp(1)</a>:
286: Add a new -3 option to scp: Copies between two remote hosts are
287: transferred through the local host. Without this option the data is
288: copied directly between the two remote hosts.</li>
289: <li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=ssh&sektion=1">ssh(1)</a>:
290: automatically order the hostkeys requested by the client based on
291: which hostkeys are already recorded in known_hosts. This avoids
292: hostkey warnings when connecting to servers with new ECDSA keys,
293: since these are now preferred when learning hostkeys for the first
294: time.</li>

508: <ul>
509: Play with your BIOS options to enable booting from a CD. The OpenBSD/i386
510: release is on CD1. If your BIOS does not support booting from CD, you will need
511: to create a boot floppy to install from. To create a boot floppy write
512: <i>CD1:4.9/i386/floppy49.fs</i> to a floppy and boot via the floppy drive.
513:
514: <p>
515: Use <i>CD1:4.9/i386/floppyB49.fs</i> instead for greater SCSI controller
516: support, or <i>CD1:4.9/i386/floppyC49.fs</i> for better laptop support.
517:
518: <p>
519: If you can't boot from a CD or a floppy disk,
520: you can install across the network using PXE as described in
521: the included INSTALL.i386 document.
522:
523: <p>
524: If you are planning on dual booting OpenBSD with another OS, you will need to
525: read INSTALL.i386.
526:
527: <p>
528: To make a boot floppy under MS-DOS, use the "rawrite" utility located
529: at <i>CD1:4.9/tools/rawrite.exe</i>. To make the boot floppy under a Unix OS,
530: use the
531: <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=dd&sektion=1">dd(1)</a>
532: utility. The following is an example usage of
533: <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=dd&sektion=1">dd(1)</a>,
534: where the device could be "floppy", "rfd0c", or

555: To do this, write <i>CD2:4.9/amd64/floppy49.fs</i> to a floppy, then
556: boot from the floppy drive.

709:

717: If your SPARC system does not have a CD drive, you can alternatively boot from floppy.
718: To do so you need to write <i>floppy49.fs</i> to a floppy.
719: For more information see <a href="faq/faq4.html#MkFlop">FAQ 4.3.2</a>.
720: To boot from the floppy use one of the two commands listed below,
721: depending on the version of your ROM.
722:
723: <ul><pre>
724: ok <strong>boot floppy</strong>
725: or

730: Make sure you use a properly formatted floppy with NO BAD BLOCKS or your install
731: will most likely fail.
732:
733: <p>
734: If your SPARC system doesn't have a floppy drive nor a CD drive, you can either
735: setup a bootable tape, or install via network, as told in the
736: INSTALL.sparc file.

777: Both of these trees are a regular CVS checkout. Using these trees it
778: is possible to get a head-start on using the anoncvs servers as
779: described <a href="anoncvs.html">here</a>.
780: Using these files
781: results in a much faster initial CVS update than you could expect from
782: a fresh checkout of the full OpenBSD source tree.

812: Rather, it is a set of notes meant to kickstart the user on the
813: OpenBSD ports system.
814: <p>
815: The <i>ports/</i> directory represents a CVS (see the manpage for
816: <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=cvs&apropos=0&sektion=1&manpath=OpenBSD+Current&arch=i386">

818: you aren't familiar with CVS) checkout of our ports. As with our complete
819: source tree, our ports tree is available via anoncvs. So, in
820: order to keep current with it, you must make the <i>ports/</i> tree
821: available on a read-write medium and update the tree with a command
822: like:
823: <p>
824: <ul><pre>
825: # <strong>cd [portsdir]/; cvs -d anoncvs@server.openbsd.org:/cvs update -Pd -rOPENBSD_4_9</strong>
826: </pre></ul>
827: <p>
828: [Of course, you must replace the local directory and server name here
829: with the location of your ports collection and a nearby anoncvs
830: server.]
831: <p>
832: Note that most ports are available as packages through FTP. Updated
833: packages for the 4.9 release will be made available if problems arise.
834: <p>
835: If you're interested in seeing a port added, would like to help out, or just
836: would like to know more, the mailing list ports@openbsd.org is a good
837: place to know.
