A simple TFTP server

Project description


A simple, extendable Python implementation of a TFTP server.


  • Easily customizable (override dyntftpd.TFTPServer and dyntftpd.handlers.*)
  • Can act as a HTTP proxy. The TFTP client can request a HTTP url, the TFTP server downloads and returns it.
  • Code is mostly unit tested and easy to read


  • Only handle RRQ requests
  • Don’t drop privileges after creating the listening socket :-(
  • No documentation but pydoc


0.4.0 (2015-04-16)

  • In HTTP handler, the cache filename contains client’s source port and human readable datetime, making debugging easier.
  • We no longer create a thread for each request.
  • API break: move load_file and unload_file from TFTP handlers to Session.
  • Use CleverHandler instead of FileSystemHandler by default.
  • Free resources if client disconnect before completing a transfert.

0.3.0 (2015-02-05)

  • Add unload_file callback in TFTPUDPHandler, called when the transfer of a file is over and successful.
  • Remove cache files for successful transfers in HTTPHandler.

0.2.1 (2014-11-06)

  • Create HTTPHandler.
  • Create CleverHandler to dispatch to HTTPHandler or FileSystemHandler depending on the requested file.

0.2.0 (2014-10-13)

  • Use ThreadingMixin to serve multiple requests at the same time.
  • Accept option blksize.

0.1.1 (2014-09-29)

  • Accept, and ignore extra request options.

0.1.0 (2014-09-08)
