Log Message:
Update to 2.0.1:

News for the 2.0.1 release

	Fixed denial of service bug in lshd.

	Fixed a bug in lsh-make-seed, which could make the program go
	into an infinite loop on read errors.

	lsh now asks for passwords also in quite (-q) mode, as
	described in the manual.

	Control character filtering used to sometimes consider newline
	as a dangerous control character. Now newlines should be
	displayed normally.

	Removed support for the non-standard alias
	"diffie-hellman-group2-sha1". The standardized name is for
	this key exchange method is "diffie-hellman-group14-sha1".

News for the 2.0 release

	Several programs have new default behaviour:

	* lshd enables X11 forwarding by default (lsh still does not).

	* lsh-keygen generates RSA rather than DSA keys by default.

	* lsh-writekey encrypts the private key by default, using
	  aes256-cbc. Unless the --server flag is used.

	Improved the lcp script. It is now installed by default.

	Implemented the client side of "keyboard-interactive" user
	authentication.

	Support keyexchange with
	diffie-hellman-group14-sha1/diffie-hellman-group2-sha1 (the
	standardized name is at the moment not decided).

	Fixes to the utf8 encoder, and in particular interactions
	between utf8 and control character filtering.

News for the 1.5.5 release

	Added SOCKS-style proxying to lsh and lshg. See the new -D
	command line option. Supports both SOCKS-4 and SOCKS-5.

	The lsh client no longer sets its stdio file descriptors into
	non-blocking mode, which should avoid a bunch of problems. As
	a consequence, the --cvs-workaround command line option has
	been deleted.

	In the user lookup code, lshd now ignores the shadow database
	if getspnam returns NULL.

	In the server pty setup code, use the group "system" as a
	fallback if the group "tty" doesn't exist. This is the case on
	AIX. (There are however more problems on AIX, which makes it
	uncertain that lshd will work out of the box).

	Deleted the --ssh1-fallback option for lshd. I hope ssh1 is
	dead by now; if it isn't, you have to run ssh1d and lshd on
	different ports.

	Deleted code for bug-compatibility with ancient versions of
	Datafellow's SSH2. There are zero bug-compatibility hacks in
	this version.

News for the 1.5.4 release

	Added logging of tcpip-forward requests.

	Includes nettle-1.9, which have had some portability fixes and
	optimizations. In particular, arcfour on x86 should be much
	faster.

	Implemented flow control on the raw ssh connection. Enforce
	limits on the amount of buffered data waiting to be written to
	the socket.

	Moved all destructive string operations to a separate file
	lsh_string.c, which has exclusive rights of accessing string
	internals. Should make the code more robust, as buffer size
	and index calculations elsewhere in the code should hit an
	assert in lsh_string.c before doing damage.

	Some general simplification and cleanup of the code.

News for the 1.5.3 release

	Fixed heap buffer overrun with potential remote root
	compromise. Initial bug report by Bennett Todd.

	Fixed a similar bug in the check for channel number allocation
	failure in the handling of channel_open, and in the
	experimental client SRP code.

	lshd now has an experimental mode similar to telnet, where it
	accepts the 'none' authentication method and automatically
	disables services such as X and TCP forwarding. This can be
	useful in environment where it's required that /bin/login or
	some other program handle authentication and session setup
	(e.g. handle security contexts and so on).

News for the 1.5.2 release

	Encrypted private keys works again.

	New client escape sequence RET ~ ?, which lists all available
	escape sequences. Also fixed the werror functions so that they
	use \r\n to terminate lines when writing to a tty in raw mode.

	Implemented handling of multiple --interface options to lshd.
	As a side effect, The -p option must now be given before
	--interface to have any effect.

	Connecting to machines with multiple IP-adresses is smarter,
	it connects to a few addresses at a time, in parallel.

	Fixed a file descriptor leak in the server tcpip forwarding
	code.

	Lots of portability fixes.

News for the 1.5.1 release

	Incompatible change to key format, to comply with the current
	spki structure draft. You can use the script lsh-upgrade to
	copy and convert the information in the old .lsh/known-hosts
	to the new file .lsh/host-acls. The new code uses libspki.

	Fixed IPv6 bug reported by Simon Kowallik.

	lshd now does the equivalence of ulimit -n unlimited, this is
	inherited by processes started upon client requests. If you
	don't want this, you should use /etc/{profile,login,whatever}
	to set limits for your users. Do note that PAM-based solutions
	will NOT work as PAM is used from a separate process that
	terminates as soon as the authentication is finished (this of
	course goes for environment variables too).

	lsh and and lshg now parses options from LSHFLAGS and
	LSHGFLAGS, these are parsed before and can be overridden by
	the command line.

News for the 1.5 release

	Implemented the server side of X11 forwarding. Try lshd
	--x11-forward. There's one known bug: The server may start
	sending data on the session channel (typically your first
	shell prompt) before it has sent the reply to the client's
	"shell" or "exec" request. lsh will complain about, and ignore
	that data.

	As part of the X11 hacking, the socket code have been
	reorganized.

	Deleted one of the ipv6 configure tests. Now lsh will happily
	build ipv6 support even if ipv6 is not available at run-time
	on the build machine.

	Fixed bug preventing -c none from working.

	Another bug fix, call setsid even in the non-pty case.

	Various bug fixes.
