SSH in some cases terminated channels with reason normal when it should have been shutdown.

Own Id: OTP-8714 Aux Id:

The function ssh:connect/4 was not exported.

Own Id: OTP-8550 Aux Id:

Aligned error message with used version (SSH_FX_FAILURE vs SSH_FX_NOT_A_DIRECTORY, the latter introduced in version 6).

Resolved race condition when another connection is started before a channel is opened in the first connection.

Own Id: OTP-8645 Aux Id: seq11577

The configuration parameter ip_v6_disabled is now available, which makes it possible for the user to alter the IP version SSH shall use.

Own Id: OTP-8535 Aux Id:

The ssh_connection:send operation now accepts infinity as timeout.

Own Id: OTP-8534 Aux Id:

The connection handler now include stack traces when a channel message is not handled correctly.

Own Id: OTP-8524 Aux Id:

In some cases SSH ceased to collect more data from the transport layer.

Own Id: OTP-8401 Aux Id: seq11479

Old release notes removed.

Own Id: OTP-8356 Aux Id:

Now clear all processes when a connnection is terminated.

Own Id: OTP-8121 Aux Id:

In some rare cases the connection handler could enter an infinite loop.

Own Id: OTP-8277 Aux Id: seq11428

If an SFTP server did not respond with EOF, the function ssh_sftp:list_dir/2/3 would enter an infinite loop.

Own Id: OTP-8278 Aux Id: seq11450

The documentation is now built with open source tools (xsltproc and fop) that exists on most platforms. One visible change is that the frames are removed.

Own Id: OTP-8201 Aux Id:

ssh_sftp:start_channel did not handle all possible return values from ssh_channel:start correctly.

Own Id: OTP-8176 Aux Id:

SFTPD did not handle rename command (version 4) correctly.

Own Id: OTP-8175 Aux Id: seq11373

If a connection manager already had been terminated it could cause a channel to generate a crash report when it was about to stop.

Own Id: OTP-8174 Aux Id: seq11377

Requests could result in badarg or badmatch EXIT messages in the connection manager if the channel no longer existed.

Own Id: OTP-8173 Aux Id: seq11379

ssh_transport:unpack/3 could cause a badarg error.

Own Id: OTP-8162 Aux Id:

The encryption algorithm aes128-cbc is now supported. Requires that crypto-1.6.1 is available.

Own Id: OTP-8110 Aux Id:

ssh_sftp:start_channel/3 did not handle timout correctly.

Own Id: OTP-8159 Aux Id: seq11386

If a progress message was not recieved after invoking ssh:connect/3 the call could hang for ever. A timeout option has also been added.

Own Id: OTP-8160 Aux Id: seq11386

A comma has been missing in the ssh.appup file since SSH-1.0.2.

Own Id: OTP-8161 Aux Id:

SSH sometimes caused a crash report at disconnect.

Own Id: OTP-8071 Aux Id: seq11319

The operation ssh_sftp:stop_channel/1 returned an exception if the connection already had been closed.

Own Id: OTP-7996 Aux Id: seq11281

SSH did not handle if supervisor:start_child/2 returned {error, already_present}.

Own Id: OTP-8034 Aux Id: seq11307

SSH no longer cause supervisor reports when a connection is terminated in a controlled manner.

Own Id: OTP-8035 Aux Id: seq11308

Ssh confused local and remote channel id's, which in some cases resulted in that messages were discarded.

Own Id: OTP-7914 Aux Id: seq11234

Ssh could not handle echo values other than 0 and 1.

Own Id: OTP-7917 Aux Id: seq11238

A crash occurred if a non-valid channel reference was received.

Own Id: OTP-7918 Aux Id: seq11238

Sftpd connections was not closed after receiving eof from a client.

Own Id: OTP-7921 Aux Id: seq11222

It was not possible to start a SFTP subsystem on certain platforms, i.e. those who do not support symbolic links.

Own Id: OTP-7930 Aux Id:

In some cases the message {ssh_cm, ssh_connection_ref(), {closed, ssh_channel_id()}} was not passed to the registered callback module.

Own Id: OTP-7957 Aux Id:

By using the sftpd option {max_files, Integer}, the message size for READDIR commands can be reduced.

Own Id: OTP-7919 Aux Id: seq11230

The erlang ssh server has presented itself incorrectly, using the special version ssh-1.99, although it never has 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.

Own Id: OTP-7795

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.

Own Id: OTP-7920 Aux Id: seq11211

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.

*** POTENTIAL INCOMPATIBILITY ***

Own Id: OTP-7807

The implementation of timeouts added as a patch in ssh-1.0.1 was slightly changed and is now documented.

Own Id: OTP-7808

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.

Own Id: OTP-7809

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.

*** POTENTIAL INCOMPATIBILITY ***

Own Id: OTP-7828

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.

Own Id: OTP-7676

Tabs could cause ssh_cli to print things in a surprising way.

Own Id: OTP-7683 Aux Id: seq11102

[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.

Own Id: OTP-7685 Aux Id: seq11082

[sftpd] - Added patch to further improve handling of symbolic links in the sftp-server.

Own Id: OTP-7766 Aux Id: seq11101

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) .

Own Id: OTP-7767

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

Own Id: OTP-7768

Improved ipv6-handling as some assumptions about inet functions where incorrect.

Own Id: OTP-7770

Added new API function ssh:connection_info/2.

Own Id: OTP-7456

Now starts ssh channel processes later avoiding synchronization problems between processes.

Own Id: OTP-7516

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.)

Own Id: OTP-7645 Aux Id: seq11094

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.

Public keys protected by a password are currently not handled by the erlang ssh application.

Own Id: OTP-6400 Aux Id: 10595

[sftpd] - Listing of symbolic link directories should now work as expected.

Own Id: OTP-7141 Aux Id: seq10856

[sftp] - When listing a directory with more than 100 files only the first 100 where listed. This has now been fixed.

Own Id: OTP-7318 Aux Id: seq10953

When restarting an ssh-system the expected return value from ssh_system_sup:restart_acceptor/2 was incorrect, this is no longer the case.

Own Id: OTP-7564 Aux Id: seq11055

A few minor bugs where fixed in ssh_userreg.erl and ssh_connection_manager and a a ssh_cli option was added to restore backwards compatibility with the old ssh_cm - API.

Own Id: OTP-7565

Fixed bug in ipv6 support and added option to disable ipv6 as a workaround for badly configured computers.

Own Id: OTP-7566

[sftp] - Option added to set timeout value in sftp.

Own Id: OTP-7305 Aux Id: seq10945

Removed some special handling of prompts that made ssh behave differently than openssh.

Own Id: OTP-7485 Aux Id: seq11025

Bug in encoding of pty opts has been fixed.

Own Id: OTP-7504

The architecture of the ssh processes has been reconstructed to fit in a supervision tree as to become a real OTP application and benefit from this when starting and stopping.

Own Id: OTP-7356 Aux Id: seq10899

Support for pty option echo off added. Requires kernel from R12B-4.

*** POTENTIAL INCOMPATIBILITY ***

Own Id: OTP-7502 Aux Id: seq10959

The ssh API has been enhanced a lot of old API functions has become deprecated.
