Added support for AES-GCM authenticated encryption in SSH protocol 2.

The new cipher is available as "aes128-gcm@openssh.com" and

"aes256-gcm@openssh.com". It uses an identical packet format to the

AES-GCM mode specified in RFC 5647, but uses simpler and different

selection rules during key exchange.

These modes alter the packet format and compute the MAC over the

packet length and encrypted packet rather than over the plaintext

data. These modes are considered more secure and are used by default

when available.

via an <tt>AuthenticationMethods</tt> option. This option lists one

via an <code>AuthenticationMethods</code> option. This option lists one

or more comma-separated lists of authentication method names.

Successful completion of all the methods in any list is required for

authentication to complete. This allows, for example, requiring a

user having to authenticate via public key or GSSAPI before they are

offered password authentication.

# <kbd>cd /usr/src</kbd>

# <kbd>tar xvfz /tmp/src.tar.gz</kbd>

<p>

# <strong>mkdir -p /usr/src</strong>

# <strong>cd /usr/src</strong>

# <strong>tar xvfz /tmp/src.tar.gz</strong>

</pre></ul>

sys.tar.gz contains a source archive starting at /usr/src/sys.

This file contains all the kernel sources you need to rebuild kernels.

To extract:

<p>

# <strong>mkdir -p /usr/src/sys</strong>

# <kbd>mkdir -p /usr/src/sys</kbd>

# <strong>cd /usr/src</strong>

# <kbd>cd /usr/src</kbd>

# <strong>tar xvfz /tmp/sys.tar.gz</strong>

</pre></ul>

Both of these trees are a regular CVS checkout. Using these trees it

is possible to get a head-start on using the anoncvs servers as

Line 796

Line 779

Using these files

results in a much faster initial CVS update than you could expect from

a fresh checkout of the full OpenBSD source tree.

The <i>ports/</i> subdirectory is a checkout of the OpenBSD ports tree. Go

read the <a href="faq/ports/index.html">ports</a> page

OpenBSD ports system.

<p>

The <i>ports/</i> directory represents a CVS (see the manpage for

cvs(1)</a> if

you aren't familiar with CVS) checkout of our ports. As with our complete

source tree, our ports tree is available via

Line 837

Line 822

available on a read-write medium and update the tree with a command

like:

<p>

# <strong>cd /usr/ports</strong>

# <strong>cvs -d anoncvs@server.openbsd.org:/cvs update -Pd -rOPENBSD_5_3</strong>

</pre></ul>

</pre></blockquote>

<p>

[Of course, you must replace the server name here with a nearby anoncvs

server.]

If you're interested in seeing a port added, would like to help out, or just

would like to know more, the mailing list

<a href="mail.html">ports@openbsd.org</a> is a good place to know.
