I am trying to upload a file to an ftp server on my same wifi network to get a picture on to a digital picture frame. I succeeded in uploading through file explorer, but when uploading using a python script I get a 530 response.
Here is the code so far
import ftplib
ftp = ftplib.FTP()
ftp.connect("111.111.1.11", 1111) #dummy host and port
file = open('C:/path/to/file/test1.png','rb')
ftp.storbinary('test.png', file)
file.close()
ftp.quit()
The server does not requre me to log in with a username and password on file explorer, is there some sort of default I need?
530 error code means Authentication failed error so you are missing the authentication piece. Maybe you can do something like this:
ftp = FTP(source_address=("111.111.1.11", 1111))
ftp.login(user, password)
Note that if you don't provide a user and password it will login with:
user anonymous
password anonymous
as described here
Also I would recommend you reading about S-FTP (Secure FTP) because in FTP the credentials are passed in clear text in the login request.
S-FTP is a communication protocol similar to FTP but built on top of ssh.
Hope this helped you !

i am getting really confused on how to connect to an ftp server while using a proxy in python. Some previous examples have confused me a lot as i am new to Python. Below are the variables i believe that will be needed in the code sample (the proxy is only a example for security reasons as is the username and password).
can someone please show me how to connect to the ftp server and download a file
the end goal is to use python to download files from this ftp server
import ftplib
proxy = {'http': "auth-proxy.xxxx.com:232", 'https': "auth-proxy.xxx.com:232"}
ftp_site = 'https://data.ftse.com'
username = 'xxxxxx'
password = 'yyyyyy'
#file path where the file is on the ftp server is below
filepath = 'https://data.ftse.com/filedownloadservlet?filename=eerf1808.csv&phyName=nXVi8I4q5Boy8gBpdpDg3jNBqfAZy0vfydRBHC3zs3qt6YadMA6xa9LM3QaIgx-g'
Actually we are using python3.6.8 in our server, we are trying to connect the ftp server and pushing files to the ftp server through an api call, here when we try to push the files from local it is running fine and files are being pushed but when calling api to the server it is redirecting to a 502 bad gateway error after 14.8s time when tried with postman. the server we use is AWS EC2
ftp = ftplib.FTP()
host = config.FTP_HOST
port = 21
ftp.connect(host, port)
try:
ftp.login(config.FTP_USERNAME, config.FTP_PASSWORD)
file = open(path_image, 'rb')
ftp.cwd("/DailyDump/target/")
ftp.storbinary("STOR sample_file_name" + str(yesterday_date) + ".csv", file)
file.close()
ftp.close()
except:
pass
This problem was caused due to the maximum timeout reached on the API call, hence I transferred the codes from API to stand alone code to make it run for longer time period without giving error. so there is no error in ftp logging.
At the moment, my networking team is downloading a firmware version using an FTP server (Filezilla).
We create an account on the server, upload the firmware to the server and then on the cisco device we use the command copy ftp://username:password#server_ip/file_name storage_device: and the device is downloading the firmware from the ftp server.
Now, i have a website created with Flask in python, that has some scripts that my team uses, and i want to add a script that allows the user to upload a file to the website, supply the ip of the device, and the script will connect to the device and pull the file from the server.
While creating an ftp server using pyftpdlib, i have encounterd some issues, as the device is logging in with the supplied user, but does not download the file.
If i log in to the server using an FTP client (FileZilla client) i can download the file separately.
I guess the issue is with the cisco device trying to download the firmware directly while connecting.
The code I used to create the python server:
import os
from pyftpdlib.authorizers import DummyAuthorizer
from pyftpdlib.handlers import FTPHandler
from pyftpdlib.servers import FTPServer
def main():
authorizer = DummyAuthorizer()
authorizer.add_user('username', 'password', '/ftp', perm='elradfmwMT')
handler = FTPHandler
handler.authorizer = authorizer
handler.banner = "Test FTP server"
address = ('0.0.0.0', 21)
server = FTPServer(address, handler)
server.max_cons = 256
server.max_cons_per_ip = 10
server.serve_forever()
if __name__ == '__main__':
main()
If anyone has encounterd any issue like that, help would be appreciated.
Thank you!
Two possible issues:
1. Watch the diskspace on the IOS device. Some platforms have very little space for extra images, so good image hygiene is essential.
2. In my various experiments, I've found that pushing the image to the device is generally more reliable than asking the device to pull the image from elsewhere. You may need to add a configuration entry "ip scp server enable". Then you can write your script to push the images diretly.
I use Paramiko to put a file to an SFTP server:
import paramiko
transport = paramiko.Transport((host, port))
transport.connect(username=username, password=password)
sftp = paramiko.SFTPClient.from_transport(transport)
sftp.put(local_path, remote_path)
Now, I would like to check if it worked. The idea is that I compare the checksum of the local file and the remote one (that is located on the SFTP server).
Does Paramiko functionality allows to do that? If it is the case, how exactly it works?
With the SFTP, running over an encrypted SSH session, there's no chance the file contents could get corrupted while transferring. So unless it gets corrupted when reading the local file or writing the remote file, you can be pretty sure that the file was uploaded correctly, if the .put does not throw any error.
try:
sftp.put(local_path, remote_path)
except:
# Something went wrong
If you want to test explicitly anyway:
While there's the check-file extension to the SFTP protocol to calculate a remote file checksum, it's not widely supported. Particularly it's not supported by the most widespread SFTP server implementation, the OpenSSH. See What SFTP server implementations support check-file extension.
If you are lucky to connect to another SFTP server that supports the extension, you can use the Paramiko's SFTPFile.check method.
If not, your only option is to download the file back and compare locally.
If you have a shell access to the server, you can of course try to run some shell checksum command (sha256sum) over a separate shell/SSH connection (or channel) and parse the results. But that's not an SFTP solution anymore. See Comparing MD5 of downloaded files against files on an SFTP server in Python.
if the file doesn't upload then the method will throw an error, so u can check for error
import paramiko
transport = paramiko.Transport((host, port))
transport.connect(username=username, password=password)
sftp = paramiko.SFTPClient.from_transport(transport)
try:
sftp.put(local_path, remote_path)
except IOError:
#'Failure'
except OSError:
#'Failure'
I'm writing a script that will connect to a remote FTP server and login using my username and password and then upload a file from my HDD to the server.
I feel like there can be alternatives to hardcoding my sensitive information (password and username) in the code. Any suggestions? What's the best thing that can be done?
import ftplib
ftp = ftplib.FTP('ftp.mydomain.com')
ftp.login('username', 'password')
