Я пытаюсь создать простой FTPS-сервер на своем экземпляре Ubuntu Amazon EC2, используя библиотеку Python pyftpdlib.
Вот код прямо из документации:
#!/usr/bin/env python
"""
An RFC-4217 asynchronous FTPS server supporting both SSL and TLS.
Requires PyOpenSSL module (http://pypi.python.org/pypi/pyOpenSSL).
"""
from pyftpdlib.servers import FTPServer
from pyftpdlib.authorizers import DummyAuthorizer
from pyftpdlib.contrib.handlers import TLS_FTPHandler
import os
def main():
authorizer = DummyAuthorizer()
authorizer.add_user('ubuntu', '*****', os.getcwd(), perm='elradfmw')
authorizer.add_anonymous('.')
handler = TLS_FTPHandler
handler.certfile = 'keycert.pem'
handler.authorizer = authorizer
handler.masquerade_address = '52.23.244.142'
# requires SSL for both control and data channel
handler.tls_control_required = True
handler.tls_data_required = True
handler.passive_ports = range(60000, 60099)
server = FTPServer(('', 21), handler)
server.serve_forever()
if __name__ == '__main__':
main()
Когда я запускаю скрипт на своем экземпляре Amazon EC2 и пытаюсь удаленно подключиться с помощью FileZilla, я получаю:

Я думаю, что я что-то упускаю. Могу ли я получить некоторую помощь?
