ConnectionRefusedError: [Errno 111] Connection refused

问题:

I was trying to use ftp and I am getting the following error:

>>> ftp = ftplib.FTP('192.168.248.108') Traceback (most recent call last):   File "<stdin>", line 1, in <module>   File "/usr/lib/python3.5/ftplib.py", line 118, in __init__     self.connect(host)   File "/usr/lib/python3.5/ftplib.py", line 153, in connect     source_address=self.source_address)   File "/usr/lib/python3.5/socket.py", line 711, in create_connection     raise err   File "/usr/lib/python3.5/socket.py", line 702, in create_connection     sock.connect(sa) ConnectionRefusedError: [Errno 111] Connection refused 

I was trying to take it step by step since the whole client and server codes were not running. Help please. Thank you.

EDIT:
This is the client side code:

from ftplib import FTP  ftp = FTP('192.168.248.128') ftp.login(user='username', passwd = 'password') ftp.cwd('/Desktop/FTP') def placeFile():      filename = 'myfile.txt'     ftp.storbinary('STOR '+filename, open(filename, 'rb'))     ftp.quit()  placeFile() 

回答1:

First of all check this ip to see if ftp service is available, and if it is check the port that it is listening on, cause it maybe (rare but possible) is configured to listen on a different port than the standard one - 21 . Also maybe the connection is blocked by a firewall, and that is why connection gets refused.

Also haven't seen the whole code of yours but I think another/different problem is this: def placeFile() should be changed to this instead def placeFile(ftp) - cause the function placeFile doesn't really know that ftp references to the ftp client you created above.
