312: <li>New features:
1.4 sobrado 313: <ul>
314: <li>Implement Elliptic Curve Cryptography modes for key exchange (ECDH)
315: and host/user keys (ECDSA) as specified by RFC5656. ECDH and ECDSA
316: offer better performance than plain DH and DSA at the same

1.4 sobrado 321: add a protocol extension to support a hard link operation. It is
322: available through the "ln" command in the client. The old "ln"

1.65 ! deraadt 324: or through the preexisting "symlink" command.

1.65 ! deraadt 328: copied directly between the two remote hosts.
1.64 bentley 329: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
1.4 sobrado 330: automatically order the hostkeys requested by the client based on
331: which hostkeys are already recorded in known_hosts. This avoids
332: hostkey warnings when connecting to servers with new ECDSA keys,
333: since these are now preferred when learning hostkeys for the first

1.64 bentley 340: <li><a href="https://man.openbsd.org/sftp.1">sftp(1)</a>:
1.4 sobrado 341: the sftp client is now significantly faster at performing directory

343: of stat(3) operations performed in the course of its execution
344: rather than performing expensive round trips to fetch them again
1.65 ! deraadt 345: afterwards.
1.64 bentley 346: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
1.4 sobrado 347: "atomically" create the listening mux socket by binding it on a
348: temporary name and then linking it into position after listen() has
349: succeeded. This allows the mux clients to determine that the server
350: socket is either ready or stale without races. Stale server sockets
1.65 ! deraadt 351: are now automatically removed. (also fixes bz#1711)

501: form of install. The instructions for doing an FTP (or other style
502: of) install are very similar; the CDROM instructions are left intact

543:
1.1 deraadt 544: <p>
545: Play with your BIOS options to enable booting from a CD. The OpenBSD/i386
546: release is on CD1. If your BIOS does not support booting from CD, you will need
547: to create a boot floppy to install from. To create a boot floppy write
548: <i>CD1:4.9/i386/floppy49.fs</i> to a floppy and boot via the floppy drive.
549:
550: <p>
551: Use <i>CD1:4.9/i386/floppyB49.fs</i> instead for greater SCSI controller
552: support, or <i>CD1:4.9/i386/floppyC49.fs</i> for better laptop support.
553:
554: <p>
555: If you can't boot from a CD or a floppy disk,
556: you can install across the network using PXE as described in
557: the included INSTALL.i386 document.
558:
559: <p>
560: If you are planning on dual booting OpenBSD with another OS, you will need to
561: read INSTALL.i386.
562:
563: <p>
564: To make a boot floppy under MS-DOS, use the "rawrite" utility located
565: at <i>CD1:4.9/tools/rawrite.exe</i>. To make the boot floppy under a Unix OS,
566: use the
1.64 bentley 567: <a href="https://man.openbsd.org/dd.1">dd(1)</a>

586: The 4.9 release of OpenBSD/amd64 is located on CD2.
587: Boot from the CD to begin the install - you may need to adjust
588: your BIOS options first.
589: If you can't boot from the CD, you can create a boot floppy to install from.
590: To do this, write <i>CD2:4.9/amd64/floppy49.fs</i> to a floppy, then
591: boot from the floppy drive.
592:
593: <p>
594: If you can't boot from a CD or a floppy disk,
595: you can install across the network using PXE as described in the included
596: INSTALL.amd64 document.

791: described <a href="anoncvs.html">here</a>.
792: Using these files
793: results in a much faster initial CVS update than you could expect from
794: a fresh checkout of the full OpenBSD source tree.

845: <p>
846: Note that most ports are available as packages through FTP. Updated
847: packages for the 4.9 release will be made available if problems arise.
848: <p>
849: If you're interested in seeing a port added, would like to help out, or just
850: would like to know more, the mailing list ports@openbsd.org is a good
851: place to know.
