Ssh 1.1.7 + +
Fixed Bugs and Malfunctions + + +

+ 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

+ + +
+ +
Improvements and New Features + + +

+ 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.

Ssh 1.1.6 + +
Fixed Bugs and Malfunctions + + +

+ 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:

+ + +
+ +
Improvements and New Features + + +

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

Ssh 1.1.5 + +
Fixed Bugs and Malfunctions + + +

+ 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.

Ssh 1.1.4 + +
Fixed Bugs and Malfunctions + + +

+ SSH sometimes caused a crash report at disconnect.

+

+ Own Id: OTP-8071 Aux Id: seq11319

+ + +
+ +
+ +
Ssh 1.1.3 + +
Fixed Bugs and Malfunctions + + +

+ 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 1.1.2 + +
Fixed Bugs and Malfunctions + + +

+ 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:

+ + +
+ +
Improvements and New Features + + +

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

+

+ Own Id: OTP-7919 Aux Id: seq11230

+ + +
+ +
+ +
Ssh 1.1.1 + +
Fixed Bugs and Malfunctions + + +

+ 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

+ + +
+ +
Improvements and New Features + + +

+ 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

+ + +
+ +
+ +
Ssh 1.1 + +
Fixed Bugs and Malfunctions + + +

+ 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

+ + +
+ + +
Improvements and New Features + + +

+ 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.

+

+ *** POTENTIAL INCOMPATIBILITY ***

+

+ Own Id: OTP-7769

+ + +
+ +
Known Bugs and Problems + + +

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

Ssh 1.0.2 + +
Fixed Bugs and Malfunctions + + +

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

+

+ Own Id: OTP-7141 Aux Id: seq10856

+ + +
+ +
+ +
Ssh 1.0.1 + +
Fixed Bugs and Malfunctions + + +

+ [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

+ + +
+ +
Improvements and New Features + + +

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

+

+ Own Id: OTP-7305 Aux Id: seq10945

+ +
Ssh 1.0 + +
Fixed Bugs and Malfunctions + + +

+ 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

+ + +
+ + +
Improvements and New Features + + +

+ 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.
