EOFError while connecting to FTP server in Python

Question

I am trying to connect to FTP server to transfer a file. Here is my code;

import ftplib
ftp = ftplib.FTP()
host = host_name
port = 22
ftp.connect(host, port)
ftp.login(username, password)

But here is the error I got. Can anybody please help me? I would really appreciate your help.

That's just a typo while writing here. I have corrected it now. Can you please take a look into the error? — Ishwor Bhatta, Mar 23 '17 at 14:29
You don't have to tell us how to log in. But it's ok. I'll live with this. :) — Bill Bell, Mar 23 '17 at 14:36

As far as I understand from the exception documentation:

exception EOFError
Raised when the input() function hits an end-of-file condition (EOF) without reading any data. (N.B.: the io.IOBase.read() and io.IOBase.readline() methods return an empty string when they hit EOF.)

This means that the server is sending you an EOF, to tell you that connection has been terminated while you were expecting to read something instead.

Looking at the method's source code and the comment above it, it says:

# Raise EOFError if the connection is closed

Many reasons to cause the server to close the connection, among them:

Firewall setup, proxy, wrong port .. etc

The question is [duplicate](http://stackoverflow.com/q/2019780/850848), so there's no point trying to answer it again. Let only with so vague answer. Rather vote for it to be closed. – Martin Prikryl Mar 23 '17 at 15:13

Very good answer! Now I understand what this error means. Moreover, I know that the problem is on server side rather on client side! – Lukasz Dynowski Jan 05 '18 at 08:32

I was able to solve the problem with following code;

import paramiko

transport = paramiko.Transport((host_name, 22))
transport.connect(username = username, password = password)
sftp = paramiko.SFTPClient.from_transport(transport)

Thanks everyone
