TFTPFTPServer

TFTPFTPServer is an open-source software project that implements both a Trivial File Transfer Protocol (TFTP) server and a traditional File Transfer Protocol (FTP) server within a single package. The dual-protocol design targets environments such as network provisioning, embedded device maintenance, and firmware distribution, where compatibility with legacy devices and boot-time processes is important.

The project is modular, with separate TFTP and FTP service components sharing a common configuration framework, logging, and runtime utilities. It is designed to be cross-platform, running on major operating systems and supporting IPv4 and IPv6 networks. The server can be managed via a configuration file and provides runtime controls for starting, stopping, and reloading settings without downtime.

TFTP support follows the standard RFC-based behavior, including read and write requests, simple block-based data transfer, and optional block-size negotiation. It supports common options such as transfer mode, timeout, and retry limits, and can constrain access with directory restrictions and per-file permissions. FTP support provides user authentication, directory listing, file uploads and downloads, and both active and passive data transfer modes. Optional encrypted connections via FTP over TLS (FTPS) may be available when compiled with TLS support.

Security considerations are central to deployment. TFTP is inherently insecure, so TFTPFTPServer typically recommends restricted network segments or chrooted directories and strict access controls. The FTP component can be configured with authentication backends, access controls, and encrypted sessions where TLS is enabled. Auditing and verbose logging help monitor transfers.

Typical deployment scenarios include network boot environments, firmware updates for devices, and controlled file distribution in LANs. The project emphasizes portability, a clean API for integration, and a permissive license to encourage community contributions. See also: TFTP, FTP.
