Sending a file to a ftp server using ftplib

Question

I'm trying to send a file to a ftp server using the ftplib library.

I have tied two different approaches.

1st)

from ftplib import FTP
ftp = FTP('HOST')
ftp.login('USERNAME','PASSWORD') 

On this case when I try to login I get the following error:

ftplib.error_perm: 550 SSL/TLS required on the control channel.

2nd)

from ftplib import FTP_TLS
ftp = FTP_TLS('HOST')
ftp.login('USERNAME','PASSWORD') 
file = open('test.xml','rb')                  # file to send
session.storbinary('STOR test.xml', file) 

In this case I can confirm that I'm able to connect and login into the server but when trying to send the file, using storbinary, I get the same error:

ftplib.error_perm: 550 SSL/TLS required on the control channel.

Any suggestions?

Answer 1

I was able to solve the problem by adding:

ftp.prot_p()          # switch to secure data connection

After

ftp.login('USERNAME','PASSWORD') 

with that I was able to perform all kind of actions on the ftp server
