I am trying to retrieve files over and https connection using python and i cant seem to find any answers that work with my case
Ive tried using ftplib and FTP_TLS but im getting errors saying that my connection is refused. I log in using my provided credentials and am able to navigate to the actual folder.
>>> ftp = FTP_TLS('HOSTNAME')
>>> ftp.login('USERNAME', 'PASSWORD')
'230 User logged in, proceed.'
>>> ftp.prot_p()
'200 Command PROT okay.'
>>> ftp.cwd('outbox')
'250 Directory changed to /outbox'
>>> ftp.nlst()
Traceback ():
output
ConnectionRefusedError: [Errno 61] Connection refused
Unsure why im getting this when everything else has been successful but i am unable to access the files
I think your FTP server is configured to return an IP address that is not reachable by the Python script. Once a server reply comes to your Python script, the Python library tries to send data to a host that it doesn't have a route to (or maybe it doesn't even exist).
Some GUI programs try to mitigate that by ignoring the server's IP replies and using the hostname that the user entered during login, but libraries don't do that.

I'm trying to connect to an FTP but I am unable to run any commands.
ftp_server = ip
ftp_username = username
ftp_password = password
ftp = ftplib.FTP(ftp_server)
ftp.login(ftp_username, ftp_password)
'230 Logged on'
ftp.nlst()
The ftp.nlst throws this error:
Error:
[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
I've tested the connection using FileZilla (running on the same machine) and it works fine.
This is FileZilla log:
Status: Connection established, waiting for welcome message...
Status: Insecure server, it does not support FTP over TLS.
Status: Logged in Status: Retrieving directory listing...
Status: Server sent passive reply with unroutable address. Using server address instead.
Status: Directory listing of "/" successful
Status: Server sent passive reply with unroutable address
The above means that the FTP server is misconfigured. It sends its internal network IP to outside network (to the client – FileZilla or Python ftplib), where it is invalid. FileZilla can detect that and automatically fall back to the original IP address of the server.
Python ftplib does not do this kind of detection.
You need to fix your FTP server to return the correct IP address.
If it is not feasible to fix the server (it's not yours and the admin is not cooperative), you can make ftplib ignore the returned (invalid) IP address and use the original address instead by overriding FTP.makepasv:
class SmartFTP(FTP):
def makepasv(self):
invalidhost, port = super(SmartFTP, self).makepasv()
return self.host, port
ftp = SmartFTP(ftp_server)
# the rest of the code is the same
In recent versions of Python (3.6 and newer), ftplib doesn't consider the IP address in PASV response on its own.
Another solution may be to use IPv6. See Python 3.8.5 FTPS connection.
For a different problem with similar consequences, see vsftpd returns 0,0,0,0 in response to PASV.
I'm trying to establish a connection with a FTP server using ftplib.
I received two files, a certificate with .crt extension and a certificate in PEM format (RSA KEY + Certificate).
I'm using the certificate in PEM format to create a context using the following code:
import ssl
from ftplib import FTP_TLS
ssl_context = ssl.SSLContext(ssl.PROTOCOL_SSLv23)
ssl_context.load_cert_chain('./certificate3')
ftps = FTP_TLS(context = ssl_context)
ftps.connect(host, porta)
ftps.login(user = user, passwd = pwd)
ftps.prot_p()
ftps.nlst()
If I remove the last command (nlst) I receive the response: '230 Logged on'.
Therefore when I try to extract list of documents inside the FTP with nlst() command I receive an error message:
TimeoutError: [WinError 10060] A connection attempt failed because the connected component did not respond
correctly after a period of time or the established connection has failed
because the connected host did not respond
Does anybody know what is wrong and how to fix the code in order to establish the connection?
I could establish connection to FTP server with WinSCP.
Through WinSCP I can run an script to synchronize the server with my local directory. Below you can find the command:
option batch abort
option confirm off
open ftp://user:password#hostserver:port -hostkey="SHA256 KEY"
synchronize local local_path remote_path
exit
This command must be in .txt file, and through a .bat file this command is executed.
Hope I can help other with the same issue.

I've been running an instance of Django on Windows R2 2012 for over a year and I've come to a road block. Yesterday something happened, I don't know what it could be. The same two errors keep popping up at different times though when trying to send an email:
[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
and
socket.gaierror: [Errno 11001] getaddrinfo failed
Users are able to connect to the IP address of the server and the port Django is running on 192.168.1.5:8000, but they cannot send emails anymore. Though a percentage do go through as described here, but very few.
Things I've tried
1) This solution
import socket
socket.getaddrinfo('localhost', 8000)
Since I'm doing python manage.py runserver 192.168.1.5:8000, I added that IP and nothing.
2) I went into the Firewall settings and made sure that the ports were all good. The SMTP one that is declared in the setting.py file in my Django project and 25. All of them, inbound and out.
3) I tried sending things on my local machine and it does work. I used other programs that do not use Django to send emails and they do process on all other machines except the Server. So I know it's not my email server.
4) I changed the email config to use my Gmail account and it does process on all other machines except for the server. So it has to be the environment.
5) Editing http_proxy environment variables
The problem, in my case, was that some install at some point defined
an
environment variable http_proxy on my machine when I had no proxy.
Removing the http_proxy environment variable fixed the problem.
As described here
and in my Django project in the wsgi.y file:
os.environ['http_proxy'] = "http://192.168.1.5:8080"
os.environ['https_proxy'] = "http://192.168.1.5:8080"
6) Given this answer here (can someone please explain how I would do it to a django email function), I've also tried this method of wrapping it from solutions here
import smtplib
import socks
#socks.setdefaultproxy(TYPE, ADDR, PORT)
socks.setdefaultproxy(socks.SOCKS5, '192.168.1.5', 8080)
socks.wrapmodule(smtplib)
smtpserver = 'smtp.live.com'
AUTHREQUIRED = 1
smtpuser = 'example#hotmail.fr'
smtppass = 'mypassword'
RECIPIENTS = 'mailto#gmail.com'
SENDER = 'example#hotmail.fr'
mssg = "test message"
s = mssg
server = smtplib.SMTP(smtpserver,587)
server.ehlo()
server.starttls()
server.ehlo()
server.login(smtpuser,smtppass)
server.set_debuglevel(1)
server.sendmail(SENDER, [RECIPIENTS], s)
server.quit()
Though I wouldn't like to use such a method as I'd prefer using Django's built in email service.
Since you have not changed the code and errors you shared shows that it's a network related problem.
It's most probably a DNS issue. In your settings.py you have specified the EMAIL_HOST, which is i believe a hostname. You need to check you server's DNS server.
You are mentioning about checking your firewall settings but what you are doing wrong is not checking the actual connection.
To address the problem you can use couple of command line utilities like telnet or nslookup. You can check if you can resolve a hostname:
nslookup smptp.mail_host.com
This command will fail most probably.
I would like to point what you did wrong in your steps:
1) You have tried to get your services getaddrinfo in which you needed to put your smtp servers hostname, which would result with the same error. Sockets are the very primitive part of the connection on the application layer, you don't really need to dig in to that.
2) Checking firewall settings is OK.
3) This is a good step which shows that there is a problem with your servers network connection.
4) That is another evidence :)
5) You have got it wrong, if you have a proxy server on your network to connect external networks, than you use this settings. But you have configured it wrong. You should not set your projects url as proxy server.
6) This is another deep level coding. You should not use such low level script, which will cause you numerious problems, which would have been handled in high level modules.
I focused my answer on the strange fact that you can get around the problem using a SOCKS5 proxy. (I believe you. There was no time to ask you for details.) You verified that your example solution by SOCKS5 works for you. Django uses the same smtplib and you can easily wrap it the same way by this code added to wsgi.py.
import smtplib
import socks # it is the package SocksiPy or PySocks
socks.setdefaultproxy(socks.SOCKS5, '192.168.1.5', 8080)
socks.wrapmodule(smtplib)
Http(s) proxy (paragraph 5)) is not related because it does not affect SMTP and other protocols except http(s) because "SOCKS operates at a lower level than HTTP proxying".
I am trying to log into a FTP server that I am only running locally in my network. To do this I have to use my ip address to use as the server address (see code below). However each time I get a gaierror: [Errno 11004] getaddrinfo failed error.
Can anyone look at my code and see if I am making any error that may be the cause of this address issue? Also I can log into the ftp server fine from my browser so I know the server is up and running correctly, also anonymous login to the server is allowed .
#import the ftp lib.
from ftplib import FTP
#enter the address of the ftp server to use, use ip address since server is ran locally
ftp = FTP('ftp://192.168.1.130')
#logs into the ftp server
ftp.login()
You're including the protocol with the hostname which is incorrect. What's happening is the library is trying to resolve "ftp://192.168.1.130" (instead of "192.168.1.130"), which isn't a valid address.
#Wrong
ftp = FTP('ftp://192.168.1.130')
#Right
ftp = FTP('192.168.1.130')
http://docs.python.org/library/ftplib.html
According to ftplib documentation, you shoud just give him the host address/IP, and not a string representing an URL. So here, you should simply do:
ftp = FTP('192.168.1.130')
