Introduce SSH Fingerprint ASCII Visualization, a technique inspired by the
graphical hash visualization schemes known as "random art", and by
Dan Kaminsky's musings on the subject during a BlackOp talk at the
23C3 in Berlin.

"Hash Visualization: a New Technique to improve Real-World Security",

Techniques and E-Commerce (CrypTEC '99)

The algorithm used here is a worm crawling over a discrete plane,
leaving a trace (augmenting the field) everywhere it goes.
Movement is taken from dgst_raw 2bit-wise. Bumping into walls
makes the respective movement vector be ignored for this turn,
thus switching to the other color of the chessboard.
Graphs are not unambiguous for now, because circles in graphs can be
walked in either direction.

Add a new MAC algorithm for data integrity, UMAC-64 (not default yet,
must specify umac-64@openssh.com). Provides about 20% end-to-end speedup
compared to hmac-md5. Represents a different approach to message
authentication to that of HMAC that may be beneficial if HMAC based on
one of its underlying hash algorithms is found to be vulnerable to a
new attack. http://www.ietf.org/rfc/rfc4418.txt

this is actually part of a larger report sent by eric s. raymond
and forwarded by brad, but i only read half of it. spotted by brad.

two changes to the new ssh tunnel support. this breaks compatibility
with the initial commit but is required for a portable approach.
- make the tunnel id u_int and platform friendly, use predefined types.
- support configuration of layer 2 (ethernet) or layer 3
(point-to-point, default) modes. configuration is done using the
Tunnel (yes|point-to-point|ethernet|no) option is ssh_config(5) and
restricted by the PermitTunnel (yes|point-to-point|ethernet|no) option
in sshd_config(5).

Add support for tun(4) forwarding over OpenSSH, based on an idea and
initial channel code bits by markus@. This is a simple and easy way to
use OpenSSH for ad hoc virtual private network connections, e.g.
administrative tunnels or secure wireless access. It's based on a new
ssh channel and works similar to the existing TCP forwarding support,
except that it depends on the tun(4) network interface on both ends of
the connection for layer 2 or layer 3 tunneling. This diff also adds
support for LocalCommand in the ssh(1) client.
