<h1>1 SSH Release Notes</h1>
<h3><a name="id56521">1.1
Ssh 2.1.2</a></h3>
<h4>Fixed Bugs and Malfunctions</h4>
<ul>
<li>
<p>
SSH quiet mode</p>
<p>
A new option to ssh:connect/3,4, quiet_mode. If true, the
client will not print out anything on authorization.</p>
<p>
Own Id: OTP-10429 Aux Id: kunagi-273 [184] </p>
</li>
<li>
<p>
Restrict which key algorithms to use</p>
<p>
A new option to ssh:connect/3,4 is introduced,
public_key_algs, where you can restrict which key
algorithms to use and in which order to try them.</p>
<p>
Own Id: OTP-10498 Aux Id: kunagi-289 [200] </p>
</li>
<li>
<p>
Confidentiality of client password</p>
<p>
Unsets clients password after authentication.</p>
<p>
Own Id: OTP-10511 Aux Id: kunagi-292 [203] </p>
</li>
<li>
<p>

</li>
</ul>
<h3><a name="id56601">1.2
Ssh 2.1.1</a></h3>
<h4>Fixed Bugs and Malfunctions</h4>
<ul>
<li>
<p>
Ssh now only sends one channel close message under all
circumstances, before it would sometimes incorrectly send
two.</p>
<p>
Own Id: OTP-10060</p>
</li>
<li>
<p>
The options check mistreated the ip_v6_disable-option,
and did not handle some, at the moment, undocumented
options correctly.</p>
<p>
Own Id: OTP-10061</p>
</li>
<li>
<p>
The channel id in a channel failure message, sent to the
peer, is now in all cases the remote channel id</p>
<p>
Own Id: OTP-10062</p>
</li>
<li>
<p>
Improved handling of multiple closes to avoid occasional
crashes when a channel is closed more than once.</p>
<p>
Own Id: OTP-10112</p>
</li>
<li>
<p>
Fix lib/src/test/ssh_basic_SUITE.erl to fix IPv6 option
typos</p>
<p>
Fixed incorrect option "ipv6_disable" to "ipv6_disabled"
as documented in the ssh manual.</p>
<p>
Own Id: OTP-10219</p>
</li>
<li>
<p>
SSH: Make "auth_methods" server option re-usable</p>
<p>
The 'auth_methods' option is used by the server side of
the SSH code to tell a connecting SSH client about the
authentication methods that are supported by the server.
The code still extracts and handles the 'auth_methods'
option from Opts in appropriate places, but the Opts
checking code in ssh.erl didn't allow that option to be
specified.</p>
<p>
Own Id: OTP-10224</p>
</li>
<li>
<p>
Use the correct channel id when adjusting the channel
window</p>
<p>
Own Id: OTP-10232</p>
</li>
</ul>
<h3><a name="id61101">1.3
Ssh 2.1</a></h3>
<h4>Fixed Bugs and Malfunctions</h4>

<p>
Own Id: OTP-9391 Aux Id: seq11838 </p>
</li>
<li>
<p>
Changed ssh implementation to use the public_key
application for all public key handling. This is also a
first step for enabling a callback API for supplying
public keys and handling keys protected with password
phrases. </p>
<p>
Additionally the test suites where improved so that they
do not copy the users keys to test server directories as
this is a security liability. Also ipv6 and file access
issues found in the process has been fixed.</p>
<p>
This change also solves OTP-7677 and OTP-7235</p>
<p>
This changes also involves some updates to public_keys
ssh-functions.</p>
<p>

Ssh 2.0.9</a></h3>
<h4>Improvements and New Features</h4>
<ul>
<li>
<p>Erlang/OTP can now be built using parallel make if you
limit the number of jobs, for instance using '<span class="code">make
-j6</span>' or '<span class="code">make -j10</span>'. '<span class="code">make -j</span>' does not
work at the moment because of some missing
dependencies.</p>
<p>

supported versions below 2.0. Since ssh-1.1 client
versions below 2.0 are correctly rejected instead of
letting the server crash later on. Alas the problem with
the presentation string was not discovered until after
ssh.1.1 was released. Now the server will present itself
as ssh-2.0.</p>

An internal function call used an incorrect parameter, which
caused problem when the old listen API was used. This was
introduced in Ssh-1.1.</p>

<h4>Improvements and New Features</h4>
<ul>
<li>
<p>
Ssh timeouts will now behave as expected e.i. defaults to
infinity only the user of the ssh application can know of
a reasonable timeout value for their application.</p>

To honor the multiplexing of channels over one ssh
connection concept ssh_sftp:connect/ [1,2,3] is
deprecated and replaced by ssh_sftp:start_channel/[1,2,3]
and ssh_sftp:stop/1 is deprecated and replaced by
ssh_sftp:stop_channel/1 and to stop the ssh connection
ssh:close/ 1 should be called.</p>
<p>
Own Id: OTP-7809</p>
</li>
<li>
<p>
Added the message {ssh_channel_up, ChannelId,
ConnectionManager} that shall be handled by the channel
callback handle_msg/2. This makes the function
handle_msg/2 a mandatory function for ssh channels
implementations which it was not in ssh-1.1.</p>

Ssh 1.1</a></h3>
<h4>Fixed Bugs and Malfunctions</h4>
<ul>
<li>
<p>
A flaw in the implementation of the supervision tree
caused the ssh daemon to close the connections to all
currently logged in users if one user logged out. Another
problem related to the supervision tree caused the closing
down of clients to leak processes e.i. all processes was
not shutdown correctly.</p>

[sftp, sftpd] - Added patch to make sftp timestamps more
correct, in the long run it would be nice to have better
support in file to be able to make it always behave
correctly now it will be correct 99 % of time instead of
almost never correct, at least on unix-based platforms.</p>

Ssh incorrectly sent the local id instead of the remote
id of a channel to the peer. For simpler cases these ids
often happen to have the same value. One case when they
do not is when the client sends an exec command two times
in a raw on the same ssh connection (different channels
of course as the channel will be closed when the exec
command has been evaluated) .</p>
<p>

Packet data could be lost under high load due to the fact
that buffered data was sometimes wrongly discarded before
it had been sent.</p>

Ssh now rejects old versions of the ssh protocol for
security reasons. (Even if they where not correctly
rejected before the connection would probably have failed
anyway due to other reasons.)</p>

New API module ssh_channel has been added. This is a
behaviour to facilitate the implementation of ssh clients
and plug in subsystems to the ssh daemon. Note that this
slightly changes the options to the API function
ssh:daemon/[1,2,3] deprecating all no longer documented
options. Note that the new API enforces the "logical way"
of using the old API e.i. making the subsystem process
part of the ssh applications supervisor tree, so missuses
of the old API are not compatible with the new API.</p>
