#initialize(endpoint, transport = :kerberos, opts = {}) ⇒ WinRMWebService

Returns a new instance of WinRMWebService.

Parameters:

  • endpoint (String, URI) —

    the WinRM webservice endpoint

  • transport (Symbol) (defaults to: :kerberos) —

    either :kerberos(default)/:ssl/:plaintext

  • opts (Hash) (defaults to: {}) —

    Misc opts for the various transports. @see WinRM::HTTP::HttpTransport @see WinRM::HTTP::HttpGSSAPI @see WinRM::HTTP::HttpSSL

Instance Method Details

#cleanup_command(shell_id, command_id) ⇒ true

Clean-up after a command.

Parameters:

  • shell_id (String) —

    The shell id on the remote machine. See #open_shell

  • command_id (String) —

    The command id on the remote machine. See #run_command

Returns:

  • (true) —

    This should have more error checking but it just returns true for now.

#get_command_output(shell_id, command_id, &block) ⇒ Hash

Get the Output of the given shell and command

Parameters:

  • shell_id (String) —

    The shell id on the remote machine. See #open_shell

  • command_id (String) —

    The command id on the remote machine. See #run_command

Returns:

  • (Hash) —

    Returns a Hash with a key :exitcode and :data. Data is an Array of Hashes where the cooresponding key is either :stdout or :stderr. The reason it is in an Array so so we can get the output in the order it ocurrs on the console.
