Deployment Method:

📝 NOTE: This applies to both open source and commercial editions of Chocolatey.

1. Enter Your Internal Repository Url

(this should look similar to https://community.chocolatey.org/api/v2/)

2. Setup Your Environment

1. Ensure you are set for organizational deployment

Please see the organizational deployment guide

2. Get the package into your environment

  • Open Source or Commercial:
    • Proxy Repository - Create a proxy nuget repository on Nexus, Artifactory Pro, or a proxy Chocolatey repository on ProGet. Point your upstream to https://community.chocolatey.org/api/v2/. Packages cache on first access automatically. Make sure your choco clients are using your proxy repository as a source and NOT the default community repository. See source command for more information.
    • You can also just download the package and push it to a repository Download

3. Copy Your Script

choco upgrade openssh -y --source="'INTERNAL REPO URL'" --prerelease [other options]

See options you can pass to upgrade.

See best practices for scripting.

Add this to a PowerShell script or use a Batch script with tools and in places where you are calling directly to Chocolatey. If you are integrating, keep in mind enhanced exit codes.

If you do use a PowerShell script, use the following to ensure bad exit codes are shown as failures:


choco upgrade openssh -y --source="'INTERNAL REPO URL'" --prerelease
$exitCode = $LASTEXITCODE

Write-Verbose "Exit code was $exitCode"
$validExitCodes = @(0, 1605, 1614, 1641, 3010)
if ($validExitCodes -contains $exitCode) {
  Exit 0
}

Exit $exitCode

This package was approved as a trusted package on 29 May 2021.

Description

The primary Microsoft distribution mechanism for OpenSSH is through Windows.
This package is no longer tested with all the original scenarios it was created for when it was the primary mechanism and it will not be fixed for edge cases like Nano or old versions of Windows.

tools\barebonesinstaller.ps1 
<#
.SYNOPSIS
Enables installing SSH even when your system does not have WOW64 or Chocolatey.
.DESCRIPTION
This script enables installing  SSH even when your system does NOT have:
  [1] Chocolatey installed
  [2] WOW64 installed
  [3] .NET Core (Nano)

The use cases are Server Nano and Server Core without WOW64 installed.

To use barebonesinstaller.ps1, expand the .nupkg that this file is contained in
and then place the \tools folder on the target system.

To push tools folder to Nano use 'Copy-Item -tosession $sessionvariable tools c:\tools -recurse'
.PARAMETER SSHServerFeature
Include SSH Server Feature.
.PARAMETER SSHServerPort
The port that SSHD Server should listen on.
.PARAMETER DeleteConfigAndServerKeys
Delete server private keys and configuration upon uninstall.
.PARAMETER Uninstall
Uninstall (default is to install)
.PARAMETER DisableKeyPermissionsReset
By default the install runs a custom utility script called "Reset-SSHKeyPermissions.ps1". This switch disables that functionality.
.EXAMPLE
.\barebonesinstaller.ps1 -SSHServerFeature

ATTENTION: This code is used extensively to run under PowerShell 2.0 to update 
images from RTM / SP1 source for Windows 7 and Server 2008 R2.  It is also
used under Powershell Core to add OpenSSH to Nano.  Test all enhancements and 
fixes under these two specialty cases (speciality for Chocolatey packagers who are 
likely up to the latest version on everything PowerShell).

  2016/09/20 - Modified by DawinJS to:
  - only grab TCP ports so that parsing PID would be reliable (and is sufficient for my purposes)
  - If -GetProcessDetails
    - parse PID
    - use "get-process" to find exe name (netstat -b is not pulling it for my scenario)
    - finds a full process path name in a Nano TP5 compatible way (WMIC)
  - If -ShowProgress - show progress bar - takes a while to grab all exe paths for all processes
  - If -FilterOnPorts - filter results for these ports before grabbing process details

     - DES is now external, in the OpenSSL library
     - GMP is no longer used, and instead we call BN code from OpenSSL
     - Zlib is now external, in a library
     - The make-ssh-known-hosts script is no longer included
     - TSS has been removed
     - MD5 is now external, in the OpenSSL library
     - RC4 support has been replaced with ARC4 support from OpenSSL

tools\Set-SSHDefaultShell.ps1 
<#
.SYNOPSIS
    This script sets the default shell options for openssh.  It is run during the opensssh universal installer and can be called separately to update the default shell exe after releated update (e.g. like updating PowerShell Core)
.DESCRIPTION
    This script is used during OpenSSH install if the appropriate package options were specified.

    It can also be used seperately (such as calling it after installing a new version of PowerShell Core 
    or updating another shell that should be the default for openssh)

    #It never really makes sense to search for cmd.exe as that is the default behavior and you shouldn't try to put old versions of cmd.exe on a newer version of windows 
    (I guess the exception would be configuring ssh to use 32-bit cmd.exe under 64-bit sshd.exe system - no I don't know why you would do that - but Murphy predicts someone out there will need to - hopefully not you)

    #"Windows Powershell" should always be at the end of a multi-filespec request because it will always be found

    #Environment variables are preferred for paths so that your call applies to windows not being on C: and folder redirection scenarios

    #If the list of path specs does not result in one or more valid results, then the default behavior (no registry keys) is used (graceful fall through)

    # ATTENTION - if you run this package under a 32-bit process on 64-bit Windows (e.g. SCCM "Package" objects), it will result in setting up 32-bit system exes as the shell for 64-bit sshd.exe


    Rules (For the sake of sanity, don't read these rules if you just want to do something simple like set Windows PowerShell to be your default ssh shell - use the examples)
    - the combined results will be in order that the filespecs are provided so that precedence can be specified for specific shell EXE filenames
    - the exes in each filespec can be the same (when searching multiple folder heirarchies for the same shell exe) or different (when giving preference to one shell EXE, but providing a fall through default if none are found)
    - wildcards can only be used in the pathname, not the filename  (filename wild cards will cause the filespec to be filtered out of the list)
    - each filespec must be searching for a SPECIFIC exe file (cannot search for <something>\*.exe nor <something>\* nor anything not ending in .exe) (any that don't match are filtered out of the filespec list)
    - each filespec result set is sorted by descending version number before being concatenated to the combined result list so that the newest of that shell exe will be chosen 
    - because early powershell core exe do not include versions in the PE header, they are sorted by full folder name which includes the version
    - the file list will only contain actually found EXEs
    - the file list is screened for known secure folders that require admin rights to update on windows configured with default security (the rest are filtered out)
    - the first valid hit in the overall resultant file list will be used.
    - if you do not want version autoselection, then specify the path exact location to the exact version you wish to have considered

.EXAMPLE
#All of these filespecs will be filtered out (dropped) because you can't wildcard the exe name, for securities sake you must know what the shell is called to use it:
-PathSpecsToProbeForShellEXEString "$env:userprofile\downloads\*.exe;c:\Program Files\PowerShell\*\P*.exe;c:\windows\system32\*"

.EXAMPLE
#PowerShell for Windows instead of default cmd.exe, if not found, default behavior (no registry key created, cmd.exe is ssh default):
-PathSpecsToProbeForShellEXEString '$env:windir\system32\windowspowershell\v1.0\powershell.exe"

.EXAMPLE
#The latest version of powershell core (including favoring the new EXE name), if not found, use windows powershell
-PathSpecsToProbeForShellEXEString "$env:programfiles\PowerShell\*\pwsh.exe;$env:programfiles\PowerShell\*\Powershell.exe;c:\windows\system32\windowspowershell\v1.0\powershell.exe"

.EXAMPLE
#The latest version of Ruby, if not found, powershell core if not found, default behavior (no registry key created, cmd.exe is ssh default)
-PathSpecsToProbeForShellEXEString "c:\tools\ruby*\bin\ruby.exe;c:\Program Files\PowerShell\*\pwsh.exe;c:\Program Files\PowerShell\*\Powershell.exe"

#I have no idea if ruby can actually be an SSH shell - just an example

.EXAMPLE
#Windows Subsystem for Linux Bash.exe, if not found, the latest version of git's bash.exe, if not found, default behavior (no registry key created, cmd.exe is ssh default)
-PathSpecsToProbeForShellEXEString "$env:windir\system32\bash.exe;$env:programfiles\Git\usr\bin\bash.exe"

#I have no idea if git's bash can actually be an SSH shell - just an example

.EXAMPLE
#Specific version of powershell core, if not found, windows powershell
-PathSpecsToProbeForShellEXEString "c:\Program Files\PowerShell\6.0.0-beta.6\Powershell.exe;c:\windows\system32\windowspowershell\v1.0\powershell.exe"

.EXAMPLE
#malware.exe filtered out because it is not in a secure folder, Specific version of powershell core, if not found, windows powershell
-PathSpecsToProbeForShellEXEString "$env:userprofile\downloads\malware.exe;c:\Program Files\PowerShell\6.0.0-beta.6\Powershell.exe;c:\windows\system32\windowspowershell\v1.0\powershell.exe"

.EXAMPLE
#malware.exe is used because of -AllowInsecureShellEXE
-AllowInsecureShellEXE -PathSpecsToProbeForShellEXEString "$env:userprofile\downloads\malware.exe;c:\Program Files\PowerShell\6.0.0-beta.6\Powershell.exe;c:\windows\system32\windowspowershell\v1.0\powershell.exe"

Release Notes for Chocolatey Packaging:
8.6.0-beta1
- contains version: 8.6.0.0p1-Beta
- The primary Microsoft distribution mechanism for OpenSSH is through Windows.
This package is no longer tested with all the original scenarios it was created for when it was the primary mechanism and it will not be fixed for edge cases like Nano or old versions of Windows.

7.6.1.1
- contains version: 7.6.1.0p1-Beta
- New parameter AlsoLogToFile enables file logging in addition to default of new ETW / Winodows EventLogging
- ensured barebonesinstaller.ps1 can take -SSHAgentFeature
- removed unused parameter DisableKeyPermissionsReset throughout
- removed DeleteServerKeysAfterInstalled
- no longer sets log level to QUIET
- updated to configure ETW logging
- switch to enable file based logging
- known issue - updating ETW on Nano is not currently working, so the package forces file logging to be enabled for
7.6.0.1
- Fixed problems with install parameter /SSHAgentFeature
1.0.0.20180202
- Set-SSHDefaultShell.ps1 - fix corrupt characters
1.0.0.20180201
- Set-SSHDefaultShell.ps1 - creates OpenSSH registry key if it is not yet present
1.0.0.20180131
- no longer automatically adds ssh-agent when installing sshd. You must specify /SSHAgentFeature if you want it installed.
1.0.0.0
- complies with new changes to installation for 1.0.0.0 and attempts migration of pre-1.0.0.0 items.
- removed switch $DisableKeyPermissionsReset
- removed switch $UseNTRights and ntrights.exe from package
- uses new 1.0.0.0 model for service users and permissions
- no longer explicitly sets TERM for new installs (unless you specify the parameter) - instead relies on default behavior of sshd.exe
0.0.24.0
- Fixed bug in uninstall (https://github.com/DarwinJS/ChocoPackages/issues/52)
- Uses new code from OpenSSH project for adding special privileges (is more compatible with newer Nano releases)
0.0.23.0

0.0.22.0
- Fix error when uninstall runs and openssh folder is already removed: https://github.com/DarwinJS/ChocoPackages/issues/49
- Fix error using PSH 5 Package Management to install on Server 2016: https://github.com/DarwinJS/ChocoPackages/issues/47
- Added switches for Default Shell configuration - for both chocolatey and barebonesinstall.ps1
(PathSpecsToProbeForShellEXEString, SSHDefaultShellCommandOption and AllowInsecureShellEXE)
Make the latest powershell core or windows powershell the default shell:
/PathSpecsToProbeForShellEXEString:$env:programfiles\PowerShell*\pwsh.exe;$env:programfiles\PowerShell*\Powershell.exe;c:\windows\system32\windowspowershell\v1.0\powershell.exe"
-PathSpecsToProbeForShellEXEString "$env:programfiles\PowerShell*\pwsh.exe;$env:programfiles\PowerShell*\Powershell.exe;c:\windows\system32\windowspowershell\v1.0\powershell.exe"
Rules and More Examples: https://github.com/DarwinJS/ChocoPackages/blob/master/openssh/tools/Set-SSHDefaultShell.ps1

This package supports the following parameters:

-params '"/SSHServerFeature"' (Install and Uninstall)
Also install sshd Windows Service - including opening port 22.
If this parameter is not included on an upgrade or uninstall and
the sshd server is installed - an error is generated. You must
use this switch to indicate you have made preparations for the
sshd service to be interrupted or removed.

-params '"/SSHAgentFeature"'
Installs SSH Agent Service even if SSHD Server is not being installed.
Requires admin rights to configure service.

-params '"/SSHServerFeature /SSHServerPort:3834"'
Allows the setup of the SSH server on an alternate port - sometimes done for security or to avoid conflicts with an existing service on port 22.

-params '"/OverWriteSSHDConf"'
Introduced in Version: 0.0.9.20170311
By default an existing sshd_conf file will not be overwritten (previous packaging versions always overwrote)
Use this switch to overwrite an existing sshd_conf with the one from the current install media

-params '"/SSHLogLevel:VERBOSE"'
Introduced in Version: 0.0.9.20170311
Allows the setup of the SSH logging level.
Valid Options: QUIET, FATAL, ERROR, INFO, VERBOSE, DEBUG, DEBUG1, DEBUG2, DEBUG3
On a fresh install LogLevel is set to QUIET

-params '"/TERM:xterm-new"'
Introduced in Version: 0.0.14.0
Allows the initial setup and subsequent update of the TERM system environment variable.
On a fresh install TERM is set to xterm whether or not this switch is used.

-params '"/SSHServerFeature /DeleteConfigAndServerKeys"' (Uninstall)
By default an uninstall does not remove config files nor server keys.

-params '"/PathSpecsToProbeForShellEXEString:$env:programfiles\PowerShell*\Powershell.exe;$env:windir\system32\windowspowershell\v1.0\powershell.exe"'
Introduced in Version: 0.0.22.0
A set of filespecs to probe for the latest version of a given shell exe. Wildcards can be used in the path, but not the filename.
The first filespec to result in a one or more valid hits will be choosen for the default SSH shell (newest version when there are multiple hits).
If not valid hits are located with the entire set of filespecs, the default behavior of not setting the registry key is taken (rather than an error).
Only exe's in either Program Files folder or either System32 folder (system32, syswow64) will considered safe. If the EXE is outside of these folders
you must use the /AllowInsecureShellEXE switch to have it configured.
Rules and Examples: https://github.com/DarwinJS/ChocoPackages/blob/master/openssh/tools/Set-SSHDefaultShell.ps1

-params '"/SSHDefaultShellCommandOption:/c"'
Introduced in Version: 0.0.22.0
Only used when /PathSpecsToProbeForShellEXEString is used and results in finding a valid shell executable.
Rules and Examples: https://github.com/DarwinJS/ChocoPackages/blob/master/openssh/tools/Set-SSHDefaultShell.ps1

-params '"/AllowInsecureShellEXE"'
Introduced in Version: 0.0.22.0
Only used when /PathSpecsToProbeForShellEXEString is used and results in finding a valid shell executable that is outside of the Programs Folders or system32.
Rules and Examples: https://github.com/DarwinJS/ChocoPackages/blob/master/openssh/tools/Set-SSHDefaultShell.ps1

-params '"/AlsoLogToFile"'
As of version 7.6.1.0p1-Beta default logging has shifted to ETW Windows Event Logging. Throwing this switch causes logging to also occur to the log file - now located in $env:ProgramData\ssh\logs.

This package has no dependencies.
