Submodules

cobbler_tftp.server.tftp module

This module contains the main TFTP server class.

class cobbler_tftp.server.tftp.CobblerRequestHandler(server_addr: Tuple[str, int], peer: Tuple[str, int], path: str, options: Dict[str, Any], api: ServerProxy, token: str, settings: Settings)

Bases: BaseHandler

Handles TFTP requests using the Cobbler API.

get_response_data()

This method has to be overridden and must return an object of type ResponseData.

class cobbler_tftp.server.tftp.CobblerResponseData(api: ServerProxy, token: str, path: str, prefetch_size: int)

Bases: ResponseData

File-like object representing the response from the TFTP server. Data is fetched from the API in chunks. These chunks may be larger than the TFTP request chunks, so the returned chunks are cached.
