Net::SFTP::Protocol::V05::Base

Wraps the low-level SFTP calls for version 5 of the SFTP protocol.

None of these protocol methods block--all of them return immediately, requiring the SSH event loop to be run while the server response is pending.

You will almost certainly never need to use this driver directly. Please see Net::SFTP::Session for the recommended interface.

open (path, flags, options)

Sends a FXP_OPEN packet to the server and returns the packet identifier. The flags parameter is either an integer (in which case it must be a combination of the IO constants) or a string (in which case it must be one of the mode strings that IO::open accepts). The options parameter is a hash that is used to construct a new Attribute object, to pass as part of the FXP_OPEN request.

    end

  attributes = attribute_factory.new(options)

  send_request(FXP_OPEN, :string, path, :long, desired_access, :long, sftp_flags, :raw, attributes.to_s)
end

rename (name, new_name, flags=nil)

Sends a FXP_RENAME packet to the server to request that the file or directory with the given name (must be a full path) be changed to new_name (which must also be a path). The flags parameter must be either nil or 0 (the default), or some combination of the Net::SFTP::Constants::RenameFlags constants.

def rename(name, new_name, flags=nil)
  send_request(FXP_RENAME, :string, name, :string, new_name, :long, flags || 0)
end

version ()

Returns the protocol version implemented by this driver. (5, in this case)
