What’s New in This Release of LabSSH?

v2.4.0

LabSSH v2.4.0 is a minor release, which means it contains new features and maintains backward-compatibility with all 2.x versions.

New Features:

  • Added support for LabVIEW 2017

  • Init.vi is no longer without a block diagram.

    This simplifies the process for creating applications with the LabVIEW Application Builder. For more information, see 3.4. Additional Exclusions.

  • The functions SFTP EZ Receive.vi, SFTP EZ Send.vi, SCP EZ Receive.vi, and SCP EZ Send.vi are now pure-LabVIEW functions.

    Previously, these functions were implemented as C code in labSSH.dll, which caused the LabVIEW UI thread to be blocked until the operation completed.

  • The Shell demo now uses a monospace font to display its output, which makes for a more familiar presentation.

v2.3.2

LabSSH v2.3.2 is a patch release, which means it is primarily a bugfix release with no new features.

Resolved defects

  • Init.vi fails when system’s primary drive letter (e.g. C:) spans multiple physical drives.
  • Installer should display PID of open LabVIEW instance so users can kill it.

v2.3.1

LabSSH v2.3.1 is a patch release, which means it is primarily a bugfix release with no new features.

Resolved defects:

  • LabSSH does not create LabSSH menu palette under Data Communication.

    Note

    Due to an installer defect in version 2.3.0, and erroneous menu entry was created in C:\Menus. This folder is automatically removed upon uninstallation, or can be safely deleted manually.

v2.3.0

LabSSH v2.3.0 is a minor release which contains new features but retains backwards-compatibility with all prior 2.x.x versions.

New Features:

  • Added support for LabVIEW 2016
  • Added support for 64-Bit LabVIEW, starting from LabVIEW 2009. Up until now, LabSSH only supported 32-bit LabVIEW.

Resolved Defects:

  • LabSSH Demo - SFTP Transfer.vi no longer aborts prematurely on very first transfer.
  • Fixed possible file corruption (extra NUL character) in SCP EZ Receive.vi.
  • SCP Receive.vi and SFTP Read File.vi: Avoid file corruption by truncating output array when actual bytes read are less initial array size.

Other Improvements:

  • Activation wizard now gives a more meaningful error message if unsupported LabVIEW version encountered
  • Activation wizard ‘nickname’ field is now auto-populated with the computer name by default.

v2.2.0

LabSSH v2.2.0 is a minor release which contains new features but retains backwards-compatibility with all prior 2.x.x versions.

New Features:

  • Support for LabVIEW 2015

Resolved Defects:

  • Activation Wizard should only attempt to activate selected versions of LabVIEW.

    Previously, the wizard would always try to activate every version of LabVIEW present on the system, even if the corresponding checkbox was unchecked. This would cause a file copy error if LabSSH was not selected for installation for that version of LabVIEW.

v2.1.0

LabSSH v2.1.0 is a minor release which contains new features but retains backwards-compatibility with all prior 2.x.x versions.

New Features:

  • Support for LabVIEW 2014

Resolved Defects:

  • Fixed Application Builder documentation: Old documentation was innacurate, and missed several critical steps.

  • New error code 402478: Unable to receive on socket. This error (-43) was previously unhandled, which resulted in generic error 402430.

  • New error code 402479: Transport encryption error. This error (-44) was previously unhandled, which resulted in generic error 402430.

  • Palette cleanup:

    • Most SCP VI’s did not have a short name.
    • Get Version.vi had no short name.
    • Shortened other short names where possible.

v2.0.0

LabSSH v2.0.0 is a major release, which means some VI’s break backward-compatibility with previous v1.x.x code.

New Features:

  • New Licensing

    With LabSSH v2.0.0, you now have the option of choosing either a Computer Based License, or a Named User License. The Computer Based License operates just like LabSSH 1.x, where only one physical computer may run LabSSH. The new Named User License, however, allows a Named User to be designated, which will allow that person (but only that person!) to run LabSSH on up to two (2) computers. With this new licensing model, we hope to accomodate the common scenario of a user working on both a workstation and a laptop computer.

  • Improved Error Handling

    Error handling has been overhauled in v2.0.0. We’ve meticulously documented every error you’ll receive while running your LabSSH-powered application. You may view the error code listing here.

  • Improved Timeouts

    Timeouts now accept millisecond values, which allows higher-resolution timeout values. Though this breaks existing applications, we feel the tradeoff was worthwhile.

  • Expanded SCP API

    We’ve added 5 new VI’s as part of the SCP API, which gives you granular control of SCP file transfers. This is great for transferring large files, as the new API will allow you to segment the transfer into small blocks. Doing this will allow you to do things such as display file progress, and prevent LabVIEW from appearing unresponsive.

  • Simplified Application Builder Support

    We’ve simplified the installation layout. If you’re building LabSSH-powered executables, you’ll find less requirements to manage manually. Specifically, “labSSH.dll” is now automatically detected, and “labSSH-1.dll” has been removed. As a result, all “DLL Path Override” inputs, which used to exist in nearly all library VI’s, have been removed.

  • Enhanced File Transfer Demos

    The demo application’s file transfer (both SCP and SFTP) demo vi’s have been enhanced to show a transfer progress bar. Use this as a starting point for implementation into your applications.

  • Challenge-Response Improvements

    When authenticating using challenge-response (i.e. keyboard-interactive) mode, we’ve made matching much more permissive. Rather than having to match the entire string, a partial match will now send the given response. For example, if your remote server issues a challenge “Please enter your password: “, you may use any of the following to match the prompt: “Please “, “enter your”, “password: “, and so on.

Backwards-Incompatible API Changes

  • Timeout Inputs now in Milliseconds

    All timeout controls are now specified in milliseconds. This applies to any VI that takes a Timeout input. To account for this change in your LabSSH-powered applications, you’ll need to multiply your existing timeout values by 1000.

  • I/O Terminals moved on the connector pane.

    In order to create a consistent development experience, some terminals were moved on the connector pane to be consistent with all VI’s which use the same terminal type (e.g. Timeout inputs).

  • DLL Path Override terminals removed. This input previously allowed you to override the filesystem path to labSSH.dll. This is no longer necessary, and was removed.
