python-pyftpdlib 1.5.6 Asynchronous and scalable Python FTP server library

The Python FTP server library provides a high-level interface to write efficient, scalable and asynchronous FTP servers with Python. It is the most complete RFC-959 FTP server implementation available for Python, and has the following traits:

  • It is lightweight, fast and scalable.

  • It uses the sendfile(2) system call for uploads.

  • It uses epoll, kqueue and select to handle concurrency asynchronously.

  • It supports FTPS (RFC-4217), IPv6 (RFC-2428), Unicode file names (RFC-2640) and MLSD/MLST commands (RFC-3659).

  • It has a flexible system of authorizers able to manage both virtual and real users.
