Python SSL FTP connection timing out

Question

I'm trying to get a connection established to a FTP server with SSL from within Python (v3.3.0). But I keep getting a timeout. I am NOT using port 990 as the SSL port (paranoid). Would that be the cause of this problem? And if so, how do I specify the port I am using?

Here's my script:

    from ftplib import FTP
    from ftplib import FTP_TLS

    ftps = FTP_TLS('ip address')

    ftps.auth()

    ftps.sendcmd('USER uname') 
    ftps.sendcmd('PASS password')

    ftps.prot_p()
    ftps.retrlines('LIST')

    ftps.close()

And here is the result:

Traceback (most recent call last):
  File "Scrpit name removed for posting", line 12, in <module>
    ftps.retrlines('LIST')
  File "C:\Python33\lib\ftplib.py", line 767, in retrlines
    conn = self.transfercmd(cmd)
  File "C:\Python33\lib\ftplib.py", line 381, in transfercmd
    return self.ntransfercmd(cmd, rest)[0]
  File "C:\Python33\lib\ftplib.py", line 742, in ntransfercmd
    conn, size = FTP.ntransfercmd(self, cmd, rest)
  File "C:\Python33\lib\ftplib.py", line 343, in ntransfercmd
    source_address=self.source_address)
  File "C:\Python33\lib\socket.py", line 424, in create_connection
    raise err
  File "C:\Python33\lib\socket.py", line 415, in create_connection
   sock.connect(sa)
TimeoutError: [WinError 10060] A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond

any advice would be greatly appreciated,

After looking at the ftplib source, it doesn't seem to want to use any port but 21.

I think you should be able to work around this, something like

import ftplib

ftplib.FTP.port = 995     # or whatever port you are using
ftps = ftplib.FTP_TLS('hostname', 'user', 'pwd')
ftps.retrlines('LIST')

Set the port through the connect

import ftplib

ftps = ftplib.FTP_TLS()
ftps.connect ('hostname', 991)

I'm using the astandard port 21 for FTP, but not the standard 990 for SSL so how would I set the SSL port ? – Thom Rogers Nov 22 '13 at 20:10
As far as I can tell, using the method above connects to the designated port. – KevinDTimm Nov 22 '13 at 20:44
IN order to isolate the problem, I changed the SSL port to the default 990, but I still have the same timeout problem. I verified the port change took by manually connecting via Filezilla client – Thom Rogers Nov 22 '13 at 20:53
