<# .SYNOPSIS Use ssh to determine OS information and the default shell for a Remote Host. .DESCRIPTION See SYNOPSIS .PARAMETER RemoteOSGuess This parameter is OPTIONAL. This parameter takes a string (either "Windows" or "Linux") that represents the type of platform you anticipate the Remote Host has. The default value for this parameter is "Windows". IMPORTANT NOTE: If you specify "Linux" and it turns out that the Remote Host is running Windows, this function will fail. So, if you're not sure, leave the default value "Windows". .PARAMETER RemoteHostNameOrIP This parameter is MANDATORY. This parameter takes a string that represents the DNS-resolvable HostName/FQDN or IPv4 Address of the target Remote Host .PARAMETER LocalUserName This parameter is MANDATORY for the Parameter Set 'Local'. This parameter takes a string that represents the Local User Account on the Remote Host that you are using to ssh into the Remote Host. This string must be in format: <RemoteHostName>\<UserName> .Parameter DomainUserName This parameter is MANDATORY for the Parameter Set 'Domain'. This parameter takes a string that represents the Domain User Account on the Remote Host that you are using to ssh into the Remote Host. This string must be in format: <DomainShortName>\<UserName> .Parameter LocalPasswordSS This parameter is MANDATORY for the Parameter Set 'Local'. This parameter takes a securestring that represents the password for the -LocalUserName you are using to ssh into the Remote Host. .Parameter DomainPasswordSS This parameter is MANDATORY for the Parameter Set 'Domain'. This parameter takes a securestring that represents the password for the -DomainUserName you are using to ssh into the Remote Host. .PARAMETER KeyFilePath This parameter is OPTIONAL. This parameter takes a string that represents the full path to the Key File you are using to ssh into the Remote Host. Use this parameter instead of -LocalPasswordSS or -DomainPasswordSS. .EXAMPLE # Minimal parameters... $GetSSHProbeSplatParams = @{ RemoteHostNameOrIP = "zerowin16sshb" DomainUserNameSS = "zero\zeroadmin" DomainPasswordSS = $(Read-Host -Prompt "Enter password" -AsSecureString) } Get-SSHProbe @GetSSHProbeSplatParams .EXAMPLE # Using a local account on the Remote Host... $GetSSHProbeSplatParams = @{ RemoteHostNameOrIP = "centos7nodomain" LocalUserNameSS = "centos7nodomain\vagrant" LocalPasswordSS = $(Read-Host -Prompt "Enter password" -AsSecureString) } Get-SSHProbe @GetSSHProbeSplatParams .EXAMPLE # Using an ssh Key File instead of a password... $GetSSHProbeSplatParams = @{ RemoteHostNameOrIP = "centos7nodomain" LocalUserNameSS = "centos7nodomain\vagrant" KeyFilePath = $HOME/.ssh/my_ssh_key } Get-SSHProbe @GetSSHProbeSplatParams #> function Get-SSHProbe { [CmdletBinding(DefaultParameterSetName='Domain')] Param ( [Parameter(Mandatory=$False)] [ValidateSet("Windows","Linux")] [string]$RemoteOSGuess = "Windows", [Parameter(Mandatory=$True)] [string]$RemoteHostNameOrIP, [Parameter( Mandatory=$True, ParameterSetName='Local' )] [ValidatePattern("\\")] # Must be in format <RemoteHostName>\<User> [string]$LocalUserName, [Parameter( Mandatory=$True, ParameterSetName='Domain' )] [ValidatePattern("\\")] # Must be in format <DomainShortName>\<User> [string]$DomainUserName, [Parameter( Mandatory=$True, ParameterSetName='Local' )] [securestring]$LocalPasswordSS, [Parameter( Mandatory=$True, ParameterSetName='Domain' )] [securestring]$DomainPasswordSS, [Parameter(Mandatory=$False)] [string]$KeyFilePath ) #region >> Prep if (!$(Get-Command ssh -ErrorAction SilentlyContinue)) { Write-Error "Unable to find 'ssh'!
