Using ftplib to connect to secure ftp server ( EOF occurred in violation of protocol )

Question

What i'm making wrong in this dead simple connect/list example? ( i'm using python 3.3 )

import ftplib


ftp = ftplib.FTP_TLS()
ftp.connect('localhost', 221, 20)
ftp.login()
ftp.prot_p()
ftp.retrlines('LIST')

Source : https://docs.python.org/2/library/ftplib.html#ftplib.FTP_TLS

Error output:

Traceback (most recent call last):
  File "C:/projects/nipples/ftps_client.py", line 10, in <module>
    ftp.login()
  File "C:\Python33\lib\ftplib.py", line 703, in login

    self._sslobj.do_handshake()
ssl.SSLEOFError: EOF occurred in violation of protocol (_ssl.c:548)

Thanks in advance.

Just a guess, I think you have to specify the certificate and the private key. However the docs says it is optional. https://docs.python.org/2/library/ftplib.html#ftplib.FTP_TLS — ρss, Jun 05 '14 at 19:51
@pss weird... it works properly on python 2.7 without specifying the cert/key — thclpr, Jun 06 '14 at 10:45

@DanielKleinstein not at all, i had to keep the ftp handler on python2.7 to keep this working :\ — thclpr, Oct 08 '15 at 23:28
