Raw Blame History

News for the 1.3.3 release:
Server suport for subsystems, and a new experimental command
line option --subsystems for lshd. An sftp-server included in
the dist, but it's mostly untested.
Better messages when the initial handshake fails.
Support for AES (formely known only as rijndael).
Simplified the internal command definition machinery.
Fixed bug in lshg; it crashed if given a host name argument
with strange characters.
Updates to SRP support, to get it closer to the latest draft.
New client option -B, which is like -N but also puts the
process in the background.
News for the 1.3.2 release:
Suspend works better, and is bound to the escape sequence
RET ~ ^Z.
News for the 1.3.1 release:
Repackaged the low-level crypto functions as the "nettle"
library. Bugfixes for serpent.
News for the 1.3.0 release:
Bugfixes (same as in 1.2.2).
constness fixes.
Deleted the complex streamed sexp-parser.
Verbose messages at KEXINIT and NEWKEYS.
Tolerate empty atoms (like in "3des-cbs,,aes256-cbc,").
If compiled with --debug-alloc, all strings are counted and
leaks detected. Fixed some minor leaks.
Changed conventions for packet handlers, all packets are freed
by connection_handle_packet, so individual packet handlers
shouldn't do that.
Handle the TSTP signal. Backgrounding still doesn't work quite
right, though.
Rewrote parts of the gaba.scm preprocessor.
News for the 1.2.0 release:
Added the lcp copying script to the distribution (although it
isn't installed automatically). No other changes.
News for the 1.1.9 release:
Some code cleanup. Removed a dozen files, four classes and
about 1k lines of code. Useful tools are make class-map and
./configure --enable-gcov.
To get gcov to work properly when running several processes in
parallell, you may also want to apply misc/libgcc2.c-patch to
gcc. The patch adds locking for the output *.da files.
News for the 1.1.8 release:
Updated the scsh support for scsh-0.5.2. Note that scsh is now
free software; the "non-commercial use" restrictions were
removed in the 0.5.2 release.
Updated the channel close logic to be compatible with other
ssh implementations.
Handle POLLERR; the previous version went into a busy loop if
poll set the POLLERR flag on any fd.
--cvs-workaround=e is now on by default. New option
--no-cvs-workaround to disable it.
News for the 1.1.7 release:
More bug fixes, most of them related to the EOF handling.
Added testcase for lshg -L, fixed the exposed bugs.
Don't output the "Userauth successful" message unless in
verbose mode.
News for the 1.1.6 release:
Fixed a bug in the testsuite framework, and discovered and
fixed a few new and old bugs (mostly related to the EOF and
channel close logic).
Improved handling of POLLHUP on Linux.
Fixed bug in lshd password authentication, which sometimes
crashed lshd.
Support for RSA keys, according to
draft-ietf-secsh-transport-09.txt. Wrote a test case for RSA
hostkeys, and fixed a bug in the ssh-rsa public key decoder.
Added support for OpenSSH style RSA keys to ssh-conv.
Changed unix_random.c to be more quiet.
Changed tcpip forwarding code to call shutdown() when it
receives an SSH_MSG_CHANNEL_EOF.
Updated the manual.
News for the 1.1.5 release:
Fixed bug in random generator seeding (spotted by jps).
More argp fixes.
Work on rsync, but still not used.
News for the 1.1.4 release:
Fixes for encrypted private keys (thanks to jps).
Updated argp, and ripped out its dependencies on getopt.
News for the 1.1.3 release:
Support for encrypted private keys (not tested).
The lshg gateway client works.
News for the 1.1.2 release:
New experimental option to lsh: --cvs-workaround. Using this
option causes lsh to fork off a few extra processes to handle
its stdio file descriptors, and avoid setting them in
nonblocking mode. One can also use for instance
--cvs-workaround=o to fork only for stdout; the optional
argument can be any combination of the characters 'i' (stdin),
'o' (stdout) and 'e' (stderr). If this turns out to be useful,
the option will probably be renamed and perhaps made the
default.
Implemented window change messages in the client.
Added signal handlers to io_backend.
Reorganized the code a little to make the lshg binary smaller.
Some work on an "interactive" class, encapsulating the
oparations one may want to do on the user's tty, including
subscription for window change events.
News for the 1.1.1 release:
First try for the gateway mode. New option -G for lsh, and a
new program lshg for talking to the gateway.
lshd forks of a new process and changes its uid for reading
user files. The only file read in this way, so far, is
~/.lsh/srp-verifier.
Improved randomness framework.
News for the 1.1.0 release:
First, note that the 1.1.x series should be considered
experimental.
New program lsh-export-key (contributed by jps, and then
hacked some more by me).
Some of the methods for public-key operations have been
improved and generalized.
News for the 1.0.6 release
Fixed bug in ssh-dss bug-compatibility.
Experimental kerberos support. New lshd option
--kerberos-passwords. Compiles with heimdal, MIT kerberos not yet
tested.
Improved handling of serialized userauth requests (not yet
used by kerberos password functions).
Hacked serpent code to support variable size keys.
Added rijndael test cases. No working serpent testcases yet.
News for the 1.0.5 release
Experimental support for RSA, using spki-style keys and
signatures.
Some reorganization of signature algorithms, to support
spki-style signatures (including rsa) properly.
Fix for key renegotiation bug reported by jps.
New algorithms bulk encryption algorithms: serpent and
rijndael. Rijndael implementation and lsh glue code
contributed by Rafael R. Sevilla. Serpent implementation by
Ross Anderson, Eli Biham, and Lars Knudsen.
New option -call to use any supported bulk encryption
algorithm; the default preference list is quite conservative.
New option --hostkey-algorithm, to tune the hostkey algorithm
preference list.
Renamed lsh_keygen and lsh_writekey to lsh-keygen and
lsh-writekey, respectively (actually happened in 1.0.4, but I
forgot to mention that).
News for the 1.0.4 release
Fixed yet another bug in the userauth logic.
Some RSA support (so far, only lsh-keygen and lsh-writekey
support RSA). 408 hours left...
Support for the transport spki format in sexp_parser.c.
News for the 1.0.3 release
Fixed bug in client userauth logic.
Configure fix: put -L and -R flags in LDFLAGS, not LIBS.
Portability fixes and some signed/unsigned cleanup.
News for the 1.0.2 release
Fixed bug in lsh_writekey, and improved the error message when
the outputfile already exists.
Fixed bug in the poll emulation in jpoll.c (noticed by
Jean-Pierre Stierlin).
Portability bugs reported by Jean-Pierre Stierlin, for
compiling on MacOS.
News for the 1.0.1 release
Various bug fixes. Spelling and grammar fixes in the manual,
contributed by Johan Myreen.
Hacked lsh user authentication to stop asking for a password
if the empty password is entered twice.
News for the 0.9.15 release
Portability fixes. Fixed 32-bit bug in the memory allocation
that appeared on alpha-linux. Fixes for HPUX compiler. Fixed
make distclean, which failed when cleaning in src/symmetric.
News for the 0.9.14 release
Added --stdin, --stdout and --stderr options to lsh.
Implemented pretty-printing of s-expressions when using the
advanced syntax.
Renamed sexp_conv to sexp-conv.
Fixed bug preventing forwarded connections from being closed
properly. Reported by Daniel Prevett and Joseph Galbraith.
New Getting Started chapter in the manual, and other
documentation updates.
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 <20> and <20>. 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 Bal<61>zs 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 Bal<61>zs Scheidler.
