FTPLIB error socket.gaierror: [Errno 8] nodename nor servname provided, or not known [duplicate]
(1 answer)
Closed 1 year ago.
I am having problems when I try to connect to a ftp server, I am using a Mac with BigSur and Python3.
Here is my code:
import ftplib
FTP_HOST = "ftp://myserver"
FTP_USER = "user"
FTP_PASS = "pass"
# connect to the FTP server
ftp = ftplib.FTP(FTP_HOST, FTP_USER, FTP_PASS)
Here what it returns:
Traceback (most recent call last):
File "/Users/adrianrodriguezgalisteo/jonsuGo/test_upload.py", line 8, in <module>
ftp = ftplib.FTP(FTP_HOST, FTP_USER, FTP_PASS)

self.connect(host)
File "/Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9/ftplib.py", line 156, in connect
self.sock = socket.create_connection((self.host, self.port), self.timeout,
File "/Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9/socket.py", line 822, in create_connection

for res in _socket.getaddrinfo(host, port, family, type, proto, flags):
socket.gaierror: [Errno 8] nodename nor servname provided, or not known
I just want to connect to the server and upload a file.
Thank you.

The host should only be myserver
FTP_HOST = "myserver"
You may need the FQDN of the servername

When I was trying out a tutorial in the internet, I failed to connect to the mqtt broker - anyone can help me on that?
import paho.mqtt.client as mqtt
broker_url = "mqtt.eclipse.org"
broker_port = 1883
client = mqtt.Client()
client.connect(broker_url, broker_port)
print(client)
Traceback (most recent call last):

The service does not exist at mqtt.eclipse.org. It was either used only as an example or the service is no longer available.
You should use another MQTT instance, maybe run a local instance instead.
I am trying to connect to SFTP server but it returns error:
[Errno 11001] getaddrinfo failed
I am using Python 3.7.3 and Paramiko version is 2.6.0
import paramiko
host_name = "sftp://81.149.151.143"
user_name = "******"
password = "******"
ssh_client = paramiko.SSHClient()
ssh_client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
ssh_client.connect(hostname=host_name, port=220, username=user_name, password=password)
ftp_client=ssh_client.open_sftp()
ftp_client.put('***/issue_1.docx', '/issue_1.docx')
ftp_client.close()
This is the full error:
Traceback (most recent call last):
File "/sftp/paramiko_bot.py", line 10, in <module>

The hostname parameter of SSHClient.connect should contain a hostname only (or in your case an IP address) – not any kind of URL.
ssh_client.connect(hostname="81.149.151.143", port=220, username=..., password=...)
Obligatory warning: Do not use AutoAddPolicy this way – You are losing a protection against MITM attacks by doing so. For a correct solution, see Paramiko "Unknown Server".
I'm trying to connect to my server using SSH with port 2022 (not 22) in Python. So I wrote the following code that uses Paramiko package:
import sys
import paramiko
try:
client = paramiko.SSHClient()
client.load_system_host_keys()
client.set_missing_host_key_policy(paramiko.WarningPolicy)
client.connect('ccap#10.40.2.222', '2022', '', 'ccap')
finally:
client.close()
But when I'm running it in my IDE (PyCharm) I get the following error:
/usr/local/lib/python3.5/dist-packages/paramiko/ecdsakey.py:164: CryptographyDeprecationWarning: Support for unsafe construction of public numbers from encoded data will be removed in a future version. Please use EllipticCurvePublicKey.from_encoded_point

You should provide username as a separate parameter, not prepended to the host address.
Look at the docs for .connect. It has username and hostnamelisted separately.
I want to send emails from my Gmail account using python. I followed steps given in this stackoverflow post: How to send an email with Python?
But, my the mails that I sent do not reach the addresses.
This is the error that I get:
Traceback (most recent call last):
File "something.py", line 24, in <module>
server = smtplib.SMTP('myserver')
File "/anaconda2/lib/python2.7/smtplib.py", line 256, in __init__

for res in getaddrinfo(host, port, 0, SOCK_STREAM):
socket.gaierror: [Errno 8] nodename nor servname provided, or not known
What should I be doing here?
What you've get is a DNS query error indicating that domain myserver does not exist.
You have to replace the argument myserver in server = smtplib.SMTP('myserver') with the actual address of SMTP server, such as smtp.mail.yahoo.com.
This is how I do it.
import smtplib
server=smtplib.SMTP('smtp.gmail.com',587)
server.starttls()
server.login('your_email#gmail.com','your_password')
server.sendmail('your_email#gmail.com','your_email#gmail.com','test email')
I'm learning Python and I tried using the FTPLib module for Python with this code:
import ftplib
connect = ftplib.FTP('ftp://www.website.com')
connect.login = ('username', 'password')
data = []
connect.dir(data.append)
connect.quit()
for line in data:
print line
(I'm aware that the website, username and password is incorrect, I used my website data which I don't want to share) I received the following error after running the code:
Traceback (most recent call last):
File "ftp.py", line 3, in <module>
ftp = FTP('ftp://www.website.com') # connect to host, default port
File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/ftplib.py", line 120, in __init__
self.connect(host)
File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/ftplib.py", line 135, in connect
self.sock = socket.create_connection((self.host, self.port), self.timeout)

for res in getaddrinfo(host, port, 0, SOCK_STREAM):

Just to clarify, I'm using Python 2.7 on a Mac. I don't think there is anymore details I could share. Thank you for your help!
Thanks Joel Hinz, I just needed to remove 'ftp://' from my hostname. Thanks!
