- Minor test cleanups.
1.31 2008.10.02

- Prevent t/03-packet.t from hanging due to high file descriptor.
(altblue at n0i.net, rt.cpan.org #6101)
- Skip some tests if Math::GMP not installed (e.g. from choosing only
protocol 2 in Makefile.PL) (Greg Sabino Mullane, reported in
rt.cpan.org #25152)
- If ENV{HOME} is not set, use getpwuid. If both fail and the dir

- Fix incorrect logical/bitwise AND mixup (Peter.Haydon at uk.fujitsu.com,
rt.cpan.org #31490)
- Allow empty stdin for SSH2 (rcp at rcable.co.uk, rt.cpan.org #32730)

(john at sackheads.org, rt.cpan.org #34874)
1.30 2005.10.12
- Fix for local *READ/*WRITE tie problem in open2 function (Bas van
Sisseren).
1.29 2005.10.08
- Require Digest::SHA1 2.10 or greater (fixed problem with BSD connection)
(Adam Callis).
- Add suppress_shell SSH2 option for SFTP (Sean McMillan).
- Use effective (not real) user-id to detect root (David Wheeler,
rt.cpan.org #13373).

than string (mark AT blackmans.org, rt.cpan.org #14549).
1.28 2005.03.17
- Patch to skip warning messages emitted by F-Secure sshd before the SSH
signature (Neal Ley).
- Fix for "Can't locate object method "blocking" via package "IO::Handle""
error (rt.cpan.org #11674, Daniel C. Silverstein (dans AT pch.net)).
1.27 2005.02.06
- Set socket to non-blocking in more portable manner (rt.cpan.org #6728).
- Default port to 22 in case service list is not available (rt.cpan.org
#5924, Gavin Brock).
- Allow Net::SSH::Ciphers::supported to take a protocol option to get
SSH2 ciphers (rt.cpan.org #4648, dan at midstream.com), and also change
Net::SSH::Perl::Kex to map SSH1 names to SSH2 names.
- Support BindAddress (bind to specific IP) (rt.cpan.org #6725, patch from
matt at katipo.co.nz).
- Have Makefile.PL only generate the prerequisites list, and not try to
install any (let the install shell handle it); this allows compatibility
with CPANPLUS and sudo installs (rt.cpan.org #6835, Michael Schwern).
1.26 2005.01.18
- New co-maintainer, David Robins (DBROBINS).
- Fix Math::Pari large integer leak in Net::SSH::Perl::Util::SSH2MP bin2mp
function (has been brought to the attention of the Math::Pari maintainer
since it's probably a Math::Pari problem, but fixed here because it's a
big win for a small change and the same "fix" is already in mp2bin).
- Require perl 5.6 in Makefile.PL (was '5.0006' change to '5.006').
1.25 2004.01.19
- Fix a bizarre test failure in 03-packet.t if String::CRC32 isn't
installed (the tests were testing SSH1 but we can't assume the
user selected this protocol). Reported by Damien Clark.
rt.cpan.org ticket #4717.
1.24 2003.11.14
- New (temporary) maintainer, Dave Rolsky.
- Fixed a number of circular references in the SSH2
implementation, which caused connections to be held open
indefinitely in a persistent environment like mod_perl. This
uses weak references, so Perl 5.6.0+ is now required. This work
was funded by Kineticode, Inc.
- Added a LICENSE file.
1.23 2001.10.04
- Added --sdk option to Makefile.PL.
- Added Net::SSH::Perl::SSH2::select_class so that Net::SSH::W32Perl
can override it and reuse client_loop.
1.22 2001.08.28
- Fixed bug with channel window sizes: Net::SSH::Perl in SSH-2 mode
was not respecting the server's channel window size, and was
sending data indiscriminately. It now buffers data to be sent and
sends it when the sshd has enough window space available. Thanks
to Megan Dorrah (and others) for the spot.
- Fix receiving STDERR in SSH-2 protocol. This was broken. Thanks to
Ulrich Scheid for the spot (and to Sagar Shah and Vicente J. Ruiz
Jurado for subsequent spots :).
- Added Channel::drain_outgoing, necessitated by the above fix to
window sizes; that fix meant that output buffers were not being
drained before EOF was sent on the channel. drain_outgoing must
now be called before EOF is sent; it continually sends outgoing
data, and checks for increased window sizes, until there is no more
data to send. This will be done automatically, of course.
- Display SSH-2 BANNER messages during authentication if the session
is interactive.
- Net::SSH::Perl::Packet now uses the third argument to syswrite
(LENGTH). This was necessary to make the module work in Perl
5.005_2, apparently. Thanks to Brian Carpenter for the spot.
- Added -2 and -1 options (SSH-2 and SSH-1, respectively) to
eg/pscp.
1.21 2001.07.18
- Fixed Handle::SSH(?:1|2)::WRITE when sending large amounts of data,
ie. data larger than the max packet size. Now we break up data
into chunks of 32000 bytes, then send each in turn. Thanks to
Doug Wilson for the spot.
- Fixed SSH1::_start_interactive (SSH-1 client loop) so that we
break the client loop on EOF reads from the sshd socket. This
should fix some hangs when calling close on a tied open2 handle.
- Better detection of exit status in Handle::SSH1.
- Handle::SSH1::READ now looks to see if we have already hit EOF
(ie. we have received exit status packet); if so, returns 0.
- Added SSH1::send_data, which allows register_handler callbacks
to be written that will (hopefully) work for both SSH-1 and
SSH-2.
1.20 2001.07.11
- A read on an open2 tied filehandle that indicates a closed connection
will now return 0 bytes instead of causing a fatal error. Thanks to
Anthony Ball for the reasoning and the fix.
- getpwuid is now called in an eval, so on systems that do not
support it, it will not cause a fatal error. Thanks to Shaun
Bramley for the spot.
- Bug with "BatchMode no" in a config file overriding interactive => 1
in the constructor is now fixed. Thanks to Doug Wilson for the spot.
- Tildes ('~') in IdentityFile config file directive were not being
expanded to $ENV{HOME} as they should have been. This is now
fixed. Thanks to Doug Wilson for the spot.
- Doug Wilson pointed out that it was impossible to use an open
SSH-1 and SSH-2 handle at the same time, because of the way
Buffer worked (setting method globs on import). This has now been
fixed throughout the distribution by using function pointers in
the object instead.
- You can now use 'stdout' and 'stderr' in SSH-1 register_handler,
as aliases for SSH_SMSG_STDOUT_DATA and SSH_SMSG_STDERR_DATA.
Thanks to Doug Wilson for the idea.
1.19 2001.07.04
- open2 interface now works with a shell, not just with running a
remote command. This allows you to open up some sort of shell
(Unix or otherwise) and talk to it directly, programatically.
Thanks to Rob J for the idea.
- Added Auth::ChallengeResponse, a generic SSH-1 challenge
response authentication mechanism; this works for TIS, s/key,
and other such mechanisms. Thanks to Surya Koneru for the idea.
1.18 2001.06.27
- Fixed bug with 'protocol' arg to Net::SSH::Perl constructor.
Protocol flag was not getting run through the Config object, which
meant it wasn't getting turned into a bitmask and staying as '1,2'.
Symptom was 'Protocol major versions differ: 1 vs. 1' or something
such. Thanks to Mark Ethan Trostler for the spot.
- Added key generation for RSA SSH-1 keys. Requires Crypt::RSA
to implement the actual generation of key data. Thanks to
Rob J for the idea.
1.17 2001.06.26
- Added (experimental) open2 method, which returns 2 tied
filehandles for reading and writing to the sshd server (or
rather to the command executed on the remote server). Thanks
to Mark Ethan Trostler for the idea, suggestions on functionality,
code patches, and testing.
1.16 2001.06.06
- Fixed bug in Net::SSH::Perl::Packet that caused client to
sometimes hang after receiving DEBUG packets.
- register_handler (for both SSH-1 and SSH-2) now takes any
'extra' arguments (other than packet type and code ref) and
will pass those arguments on to your callback function. This
allows callbacks access to otherwise private variable states.
Thanks to Mark Ethan Trostler for the idea and a patch.
- Didn't need @EXPORT_OK in Net::SSH::Perl::Util, so took it
out.
1.15 2001.06.03
- Agent authentication is now supported for both SSH-1 and
SSH-2 (SSH-2 agent is compatible with OpenSSH ssh-agent).
- Added Net::SSH::Perl::Agent, which provides a client
interface to an authentication agent.
- Added IO::Socket as a prereq (for Net::SSH::Perl::Agent).
- Abstracted out authentication management for SSH-2 login
to Net::SSH::Perl::AuthMgr class. Holds authentication
context and state during authentication negotiation and
setup, and dispatches to appropriate functions based on
packet types.
- KeyboardInt auth now uses new AuthMgr::register_handler
method.
- pssh-keygen now changes permissions of private key file
to 0600 on key generation.
- Fixed bug where pssh-keygen RSA key generation was
incompatible with OpenSSL (ie. OpenSSH); Crypt::RSA uses
ipmq (inverse of p mod q), and OpenSSL uses iqmp
(inverse of q mod p). So we now explicitly force
generation of iqmp when writing private key files.
- Key::RSA::keygen no longer forces generation of CRT
(Chinese Remainder Theorem) members, because Crypt::RSA
now does this itself on key generation.
- Net::SSH::Perl::Packet::read_poll now handles IGNORE
messages, as well as handling DISCONNECT and DEBUG messages
more intelligently (depending on protocol version).
1.14 2001.05.24
- Added keyboard-interactive authentication (only usable in
an interactive session).
- Fixed Net::SSH::Perl::Key, which was unconditionally pulling
in MIME::Base64, Digest::SHA1, and Digest::BubbleBabble. This
caused problems for users of SSH1 protocol, for which these
modules shouldn't be prereqs (thanks to Jason Tolsma for
the spot). These modules are now conditionally loaded.
- Fixed 5.005_03 syntax error in Key::RSA (calling variable
method w/o parens).
- Fixed Key::RSA so that it works with version 1.42 of
Crypt::RSA.
1.13 2001.05.14
- Added Channel::check_window method to check the local "window"
size of a channel object. Channels manage how much data they
receive using the window, and the sshd refuses to send more
data than is available in the window. We need to send an
adjust message to increase the size of the window,
periodically. Found this bug through working with Net::SFTP
(thanks to Matt Good for the initial spot).
1.12 2001.05.13
- Added ChannelMgr::register_handler to set handlers for
specific packet types for all channels. Moved default
handler initialization into init method.
- Abstracted quit_pending behavior into two methods,
break_client_loop and _quit_pending. The former can be
used by packet handlers, buffer handlers, etc. to force
breaking out of the client loop.
- Added length arg to mp2bin.
1.11 2001.05.11
- Auto-detect SSH2 private key files as identity files and read
them accordingly. Thanks to Matt Good for the original idea
of reading SSH2 key files, as well as the patch.
1.10 2001.05.11
- Added Key::RSA, an SSH2 key implementation, using Crypt::RSA;
this provides support for the 'ssh-rsa' public key
negotiation. Also supported by pssh-keygen (even for key
generation).
- Added HostKeyAlgorithms as a supported config option to set
server host key algorithms.
- Restructured DSA/publickey-auth implementation to allow for
multiple public key algorithms, not just DSA. Moved Auth/DSA
=> Auth/Pubkey.
- Added support for determining PEM private key file types (eg.
RSA vs. DSA) from the first line of the PEM file.
- Fixed broken Rhosts-RSA support (SSH1).
- Added support for reading/writing comments from read_private
and write_private method for RSA1 SSH1 keys (-c option in
pssh-keygen).
- Renamed Key::RSA to Key::RSA1 to allow for Key::RSA as SSH2
RSA implementation.
- Changed Key::DSA::size to use Crypt::DSA::Key::size; removed
redundant Key initialization from Key::DSA::init.
- Kex::DH1 now works with any type of server public key, not
just DSA (ie. also works with ssh-rsa in addition to ssh-dss).
1.06 2001.05.07
- Fixed bug with Blowfish cipher in SSH1 protocol; symptom would
be "Corrupted check bytes on input" after sending the
RSA-encrypted session key, and turning on encryption.
This was due to an incorrect key length when setting the
Blowfish key. Thanks to Dan Berger for the spot.
1.05 2001.05.04
- Fixed bug when entering password at prompt; entering an
incorrect password more than three times would cause the
authentication to hang. Thanks to Matt Good for the spot and
a fix.
1.04 2001.05.04
- Fixed bug in version/protocol exchange that was causing a DSA
signature verification error. I was cutting off just a newline,
and some versions of ssh2 were sending ctrl-M characters as
well that should be cut off. This caused errors like "DSA
verification failed for server host key" during key exchange.
Thanks to Matt Good for the spot.
- Fixed host wildcard matching in Net::SSH::Perl::Config so that
the directive 'Host foo' no longer matches the host 'foobar';
this was incorrect behavior and inconsistent with ssh.
- Added more documentation for Key::DSA and Key::RSA.
1.03 2001.05.03
- Fixed error with Net::SSH::Perl::Key::DSA and MIME::Base64.
- Added better docs for Key classes.
1.02 2001.05.03
- Fixed some doc errors, both syntax and content.
- Reworked Makefile.PL to give more feedback about what's
happening w/r/t testing prerequisite modules. Added
Digest::BubbleBabble as optional prereq, and made Convert::PEM
optional as well.
- Added support for bubble-babble fingerprints, both in
Key libraries (restructured to work with multiple types
of fingerprinting) and in pssh-keygen (-B option).
1.01 2001.05.02
- Added SSH2 support.
- Added Channel, ChannelMgr classes to manage open SSH2
channels.
- Added Key and subclasses Key::DSA, Key::RSA; managed
access to keys and keyfiles.
- Split Util functions into sub-modules that are loaded
on demand. Added more utility functions for SSH2 bigints,
etc. Deprecated _load_private_key, _save_private_key,
_load_public_key, in favor of usage of Net::SSH::Perl::Key
classes.
- Changed Constants implementation; don't use 'constant'
module, just keep constants in hash, then export them
in custom import method.
- Added eg/pssh-keygen, which has *almost* all of the
functionality in the OpenSSH ssh-keygen.
- Added Mac classes for MAC packet integrity.
- Added Cipher/RC4, an arcfour implementation (only for
SSH2).
- Added Kex and subclass for Diffie-Hellman Group 1.
- Buffer now works for both SSH1 and SSH2; different
mp_int representations.
- SSH1 implementation: now uses Net::SSH::Perl::Comp for
compression; uses Net::SSH::Perl::Key::RSA to hold RSA
keys; now lives in Net::SSH::Perl::SSH1 and is loaded on
demand; etc.
0.67 2001.04.20
- now use _mp_linearize in _rsa_private_decrypt.
- fixed bug with sending large STDIN packets. The symptom was
that, when trying to send STDIN packets larger than MAX_PACKET_SIZE,
you'd get an error and the packet wouldn't be sent. Thanks to
Chris Beatson for the spot and a patch.
- fixed odd bug with _mp_linearize. Aaron Paetznick
pointed this out, and I could only reproduce it on his system.
The symptoms were that encryption would not work, resulting in
"Corrupted check bytes on input" messages after encryption was
turned on. This was due to a problem generating the session ID.
Fixed by using a whole new version of _mp_linearize.
0.66 2001.03.22
- fixed bug where calling 'cmd' more than once wouldn't get
anything in returned stdout, stderr, or exit status. Thanks
to John Tyrrell for the spot.
0.65 2001.03.21
- fixed bug with "Cipher <name>" in config file or 'options'
param. This wasn't mapping ssh cipher names to Net::SSH::Perl
cipher names (ie. should map 'idea' => 'IDEA'). Thanks to
Edward Vopata for the spot and a patch.
- made it clearer that Net::SSH::Perl currently supports only
SSH1 protocol.
- better error checking for getservbyname lookup of ssh
service (to get default port).
- added eg/remoteinteract.pl, which demonstrates how to interact
with a remote (interactive) command.
0.64 2001.03.13
- fixed bug in Net::SSH::Perl::Cipher::new_from_key_str;
empty key string (passphrase) was broken. This never
cropped up in regular usage, only in testing.
- added _save_private_key function to Net::SSH::Perl::Util,
used to save private key files.
- added cipher tests (05-cipher.t).
- PasswordPromptLogin and PasswordPromptHost config options
are now supported (on by default).
- added untainting code for all places where data is read
from external sources (ie. socket, key files, etc.),
which should fix the "Corrupted check bytes" errors when
using -T. It was breaking because substr replacement
doesn't work on tainted values. See this p5p thread:
http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2000-09/msg00799.html
0.63 2001.03.09
- added documentation to pssh (eg/pssh), as well as a -V
option.
- fixed bug where User specified in config file would be
overridden by lack of user in login method.
- return value of buffer->dump method no longer contains
extra space at the end.
0.62 2001.03.08
- fixed test bug with StringThing package by adding FILENO
method. Should fix problem with 5.6 test suite.
- added merge_directive method to Net::SSH::Perl::Config,
and 'options' arg to Net::SSH::Perl constructor.
0.61 2001.03.07
- changed in_leftover implementation and name. The method
is now named incoming_data, and the implementation is
a Net::SSH::Perl::Buffer object.
- changed to using non-blocking sockets. Net::SSH::Perl::Packet
added a read_poll method, which doesn't block; read still
blocks (using select).
- added shell connection functionality, and abstracted out
interactive session code a bit better. Added pty support.
In the future 'shell' could conceivably be used to execute
multiple commands over the same ssh connection.
- added 3DES as fallback cipher if IDEA isn't supported.
- _check_host_in_hostfile now returns HOST_NEW if the hostfile
can't be opened, consistent with how ssh and openssh work.
0.60 2001.03.02
- added compression support, along with Compression and
CompressionLevel config directives, and docs
- added ability to register handlers for specific packet
types read during the client loop
0.53 2001.02.28
- added Net::SSH::Perl::Config; reads ssh config files
and merges constructor options with config options
- updated DESCRIPTION for Net::SSH::Perl
0.52 2001.02.21
- added ability to specify RSA identity files; defaults
to "$ENV{HOME}/.ssh/identity"
- Blowfish cipher will try to use Crypt::Blowfish_PP if
it can't use Crypt::Blowfish
- added lots of POD
- fixed bug where unknown hosts wouldn't be added to
hostfile
- sorted out common sections between Net::SSH::Perl POD
and README
0.51 2001.02.20
- Blowfish support has now been added.
0.50 2001.02.19
- moved my Net::SSH libraries into the Net::SSH::Perl
namespace; hooked up the main Net::SSH interface lib.
- added ssh and issh wrappers around OO methods.
- added configure method to Net::SSH interface; used to
set up connection params when using procedural
interface.
- added RSA authentication.
- ripped out IO::Socket usage, replaced with manual
socket creation and connection so we can try to bind to
ports 1023 down through 512, if the user wants to
connect on a privileged port.
- added Rhosts-RSA and Rhosts authentication, with the
caveat that they only work when running as root
and on a privileged port.
0.03 2001.01.19
- integrated modified CBC and CFB ciphers into distribution;
no more reliance on Crypt::CFB and Crypt::CBC
- improved cipher checking; added list of ciphers supported
by client, based on which cipher drivers can be loaded
- fixed rsa_private_decrypt bug (occurred when session key
int was 255 chars long as hex string, rather than 256).
- Chip Turner, author of Math::GMP, added my patch to his
distribution, thus making installation much easier. Thanks
Chip.
- added cipher support to installation process.
- abstracted the auth plugins into Auth modules; this will
allow the addition of other authentication modules in
the future.
- moved utility routines into Net::SSH::Util.
- changed Net::SSH::Constants to use Exporter.
0.02 2001.01.18
- added DES and 3DES ciphers
- more host key support: adds new host keys to user host key file
- checked for unsupported Net::SSH::Buffer methods in AUTOLOAD
- added example script, eg/cmd.pl
- can now specify cipher via new method
- checks against server's supported cipher list
0.01 2001.01.10
- original version; created by h2xs 1.19
