News for the 0.9.13 release New program lsh-decode-key and script ssh-conv, for converting OpenSSH/ssh2 keys to sexp format. Updated SRP support to the draft doc/srp-spec.txt. Made it possible to skip the userauth sub-protocol when using SRP. The proxy program was probably broken in the process. Fixed lsh-authorize, to use the right options to sexp_conv. Let $HOME override the home directory in the passwd database, when running as non-root. News for the 0.9.10 release Fixed bug that caused buffered output to be lost at channel close. Experimental SRP support. New program srp-gen. Improved the hex dumps in debug output. News for the 0.9.9 release autoconf fixes. Add -R-flags when appropriate. Recognize gmp-3.x. Added --with-lib-path option. Portability fixes. News for the 0.9.7 release Experimental IPv6 support. Experimental support for encrypted private keys (for now, only in lsh_writekey). wtmp logging. Improved behaviour of --port and -z options. News for the 0.9.2 release Improved support for shadow passwords. Some preparations for gateway mode. News for the 0.9.1 release Support for remote commands directly on the lsh command line. New options -S and -E. More features in the proxy. News for the 0.2.9 release Fixed bugs in the length checking of incoming packets. News for the 0.2.8 release Reworked i/o and the CHANNEL_OPEN mechanism. Seems to fix the crash when requesting forwarding to a port that doesn't answer. Also close ports for local and remote forwarding properly. Updated the proxy code. News for the 0.2.7 release Bug fixes for compialtion on Solaris. News for the 0.2.6 release Bugfixes for tcp forwarding functions. Some more tests for testsuite. To try them, you must first setup lsh so that you can login with no password. Then type "make check-more" in the testsuite subdirectory. News for the 0.2.5 release Bugfixes. News for the 0.2.3 release Added lshd options --password, --no-password, --publickey and --no-publickey, for configuring the set of supported userauth methods. Changes to the proxy program (Bazsi). News for the 0.2.2 release Bug fixes. Verbose messages on algorithm selection. News for the 000.2 release Bugfixes. New --pty-support and --no-pty-support options for lshd. News for the lsh-0.1.20 release Bugfixes. New test script for lsh_writekey. News for the lsh-0.1.19 release Lots of bugfixes. Reading of ~/.lsh/known_hosts and ~/.lsh/identity seems to work. New contrib sub-directory. News for the lsh-0.1.18 release lsh now reads ACL:s from the ~/.lsh/known_hosts file. First attempt at a m4-based testsuite. It depends on m4 being able to handle the eight-bit quote characters » and «. If your m4 doesn't do that, get the latest beta of GNU m4 or recompile GNU m4-1.4 with CFLAGS=-funsigned-char. News for the lsh-0.1.17 release More support for host authentication and SPKI. First version that includes Bazsi's work on an ssh-proxy (i.e. a program that implements the traditional Man-in-the-middle attack on the ssh2 protocol). Could be useful for people running firewalls, and also for those of us who want to point out that it's a bad idea to use unauthenticated hostkeys. News for the lsh-0.1.16 release Some preparations for real host authentication. News for the lsh-0.1.15 release Support for publickey user authentication. A new script lsh-authorize. News for the lsh-0.1.14 release First try on daemonization support. Better tracing; try --trace to get some more information than with -v, but without all the boring information generated by --debug. Generally nicer options and help mesasges, thanks to argp. Better handling of i/o exceptions. lshd should no longer crash when connections behave unexpectedly. News for the lsh-0.1.12 release Tried to fix bugs related to channel close. In the process, improved the resource mechanism, and let each channel have it's own list of resources. Fixed configure.in to handle systems with neither scsh or guile installed. News for the lsh-0.1.11 release Support for other scheme implementations in the build process, in particular guile. News for the lsh-0.1.10 release Fixed bug in sexp parser and lsh_writekey. Merged more of bazsis patches. News for the lsh-0.1.9 release Lot's of bug fixes. This version actually seems to work. Bazsi's public key patches is in, although I haven't been able to test them. The SEXP parser is rewritten to use the new exception framework. The program that makes the most of of this right now is lsh_writekey. Its core reads like (params (private object io_write_file_info) (public object io_write_file_info)) (lambda (backend) (let ((key (read (stdin backend)))) (prog1 (transport (open backend public) (private2public key)) ; FIXME: Add encryption here (canonical (open backend private) key)))))) The sexptest program has been renamed to sexp_conv. It reads an sexp (for now, only canonical and transport syntax are supported) on stdin, and prints it using advanced, transport or canonical syntax. More features could be added. The --debug option now dumps both sent and received packets, and it includes a human readable name of the packet type. Packets of type SSH_MSG_USERAUTH_REQUEST are suppressed, however, because they typically contains user passwords. There is one known bug: Running without pty allocation (lsh -nt) doesn't work, at least not for me. News for the lsh-0.1.8 release Reworked all the error handling to use exceptions. No new features, but lots of new bugs. There are no official releases numbered 0.1.4 -- 0.1.7. However, these version numbers are used for Bazsi's unofficial releases during the summer. The unofficial releases feature public key user authentication and better compatibility with Datafellow's ssh2 products. News for the lsh-0.1.3 release Local forwarding (-L) works. -R is slightly broken. News for the lsh-0.1.2 release First user visible tcpforwarding (-L option). Not tested yet... Fixed flow control. DSA signatures should conform better both to the draft andd to the ssh-2.x implementations. Better handling of POLLHUP. News for the lsh-0.1 release Added compiler.scm to the dist. Changed the session key generation to comply with the latest draft (pointed out by Joseph Galbraith). Added IDEA support (Bazsi). Fixes to pty handling and flow control (mostly Bazsi). Fixed the client side handling of userauth failures. By default, if we are running with a pty, use the same fd for stdout and stderr. This workaround should make lsh more friendly to bash and other programs that expect stderr to be a tty. NEWS for the 1999-04-25 snapshot: Fixed a few bugs in pty and eof handling. Should now work about as well as the 03-17 snapshot. Also removed most old #if:ed out code. NEWS for the 1999-04-20 snapshot: Internal reorganization. Implemented the "control language". And some bug fixes. See ChangeLog for all the details. NEWS for the 1999-03-17 snapshot CAST and TWFOFISH seem to work now. Includes a lambda->SK compiler. Bugfixes. NEWS for the 1999-03-08 snapshot No user visible changes. Added a instance variable to keep track of the amount of buffered data in the write_buffer objects (needed to fix the broken flow control). Added a generic doubly linked list, currently used by the write_buffer and resource_list classes, but which will be needed for more things (see the CONTROL item on the TODO list). NEWS for the 1999-03-07 snapshot Improved CFMAKERAW. Ugly fix for the UNIX98-style pty:s support. Twofish support (not quite working). Started on tcp forwarding (Bazsi). Some support for broken ssh2 signatures (Baszi). Needs some more work. Various bugfixes. NEWS for the 1999-02-28 snapshot Portability fixes for Solaris. NEWS for the 1999-01-28 snapshot Some PTY support Integrated support for sshd1 fallback (not tested) Bug fixes. NEWS for the 1999-01-14 snapshot Fixed off-by-one bug in dss_keygen. Some portability fixes (sys/poll.h, crypt.h, unistd.h). NEWS for the 1999-01-08 snapshot: New program lsh_writekey. NEWS for the 1999-01-05 snapshot: Command line options to select which algorithms to use. Various bug fixes. The 3des and blowfish support seems do work now. NEWS for the 1999-01-01 snapshot: ZLIB support. (Bazsi) Long key support (needed for 3DES) (Bazsi). Fixed configure test for shutdown(). Various bug fixes (Ray). NEWS for the 1998-12-26 snapshot: New lsh_keygen program. NEWS for the 1998-12-21 snapshot: Moved most objects in crypto.c and abstract_crypto.c into separate files. Added a workaround for Datafellows ssh2 client, which (contrary to the specification) asks for protocol version 1.99. Use /dev/urandom, if available. Collect most object files into liblsh.a. Started on a key generation program. TASKLIST and NOTES files now included in the snapshot. NEWS since the 1998-12-17 snapshot: Support for md5 (by Balázs Scheidler). Various bugfixes. NEWS since the 1998-12-11 snapshot: A resource mechanism (resource.[ch]) used by the server to cleanup properly when a connection dies unexpectedly. Can be used to kill child processes, close files and ports, etc. Generic code for chaining ciphers (crypto_cbc()) and piping them together (crypto_cascade()). Some untested support for blowfish and 3DES. A -c command line option is needed. A few bugfixes. Thanks to J.H.M. Dassen (Ray) and Balázs Scheidler.
