Python module ftplib FTP_TLS - Error 530 - python

I'm using Python 2.7 on ubuntu 11.10 distribution.
I have a problem with ftplib module and FTP_TLS connection.
On my ftp server there is vsftp
When try a connection I receive this error:
ftplib.error_perm: 530 Please login with USER and PASS.
This is my code:
from ftplib import FTP_TLS
ftp = FTP_TLS( '192.168.1.5' )
ftp.login( 'user' , 'password')
ftp.close()
Anyway if I use the simple FTP connection, ftp = FTP('192.168.1.5') , it works!
But I need FTP_TLS connection. I tried also to insert param ftp.auth() and ftp.prot_p() but nothing happens.

The FTP_TLS class doesn't seem to handle logins very well right now. Unfortunately, you have to explicitly send those commands to the server yourself.
from ftplib import FTP_TLS
# Do *not* specify the user and password in the FTP_TLS constructor arguments.
# Doing so will cause ftplib to try to login, resulting in the 530 error.
ftp = FTP_TLS('ftp.somewhere.com')
ftp.sendcmd('USER myusername') # '331 Please specify the password.'
ftp.sendcmd('PASS mypassword') # '230 Login successful.'

Try TLS Lite or M2Crypto both are FTP/TLS client and server.

FTP connection working on FileZilla and command line but not python ftplib

I have an ftp server deployed on aws. I can connect to it from FileZilla as well as from the command line. However, the python script I have gives me:
OSError: [Errno 101] Network is unreachable
I know that my script works since I can connect to other servers.
def test_connection():
server = ftplib.FTP()
server.connect('xx.xxx.xxx.xx')
server.login('xxxx', 'xxx')
print(server.dir())
server.quit()
if __name__ == "__main__":
test_connection()
Any clues what this could be ?
Many thanks :)
You may want to restructure your code so that credentials are initialized in the FTP constructor call.
import ftplib
server= ftplib.FTP('server.address.com','USERNAME','PASSWORD')
print(server.dir())
session.quit()
Use ftplib.FTP_TLS instead if you FTP host requires TLS.
What worked in the end:
I changed the vsftpd config:
listen=YES
listen_ipv6=NO
Not exactly sure though what the problem is

how to download a directory from ftps server using python in windows

I need to login ftps server in windows,am attaching the code which i tried to make a connection with ftps.
from ftplib import FTP_TLS
ftps = FTP_TLS('my host addres',990)
ftps.login('username','password')
ftps.prot_p()
ftps.retrlines('LIST')
when i execute this code am getting a socket error no 10060.i knew my ftp connection is implicit.I am very new to python.so please anyone help me out to solve this issue.
here is the answer for my question.in python there is one module called chilkat with that i can able to login into my implicit ftps server.
import sys
import chilkat
ftp = chilkat.CkFtp2()
# Any string unlocks the component for the 1st 30-days.
success = ftp.UnlockComponent("Anything for 30-day trial")
if (success != True):
print(ftp.lastErrorText())
sys.exit()
# If this example does not work, try using passive mode
# by setting this to True.
ftp.put_Passive(False)
ftp.put_Hostname("ur host ip")
ftp.put_Username("usename")
ftp.put_Password("passowrd")
ftp.put_Port(990)
# We don't want AUTH SSL:
ftp.put_AuthTls(False)
# We want Implicit SSL:
ftp.put_Ssl(True)
# Connect and login to the FTP server.
success = ftp.Connect()
if (success != True):
print(ftp.lastErrorText())
sys.exit()
else:
# LastErrorText contains information even when
# successful. This allows you to visually verify
# that the secure connection actually occurred.
print(ftp.lastErrorText())
print("FTPS Channel Established!")
# Do whatever you're doing to do ...
# upload files, download files, etc...
localFilename = "c:/temp/hamlet.xml"
remoteFilename = "hamlet.xml"#the file name which u download from the ftps
# Download a file.
success = ftp.GetFile(remoteFilename,localFilename)
if (success != True):
print(ftp.lastErrorText())
ftp.Disconnect()

Upload file via SFTP with Python

I wrote a simple code to upload a file to a SFTP server in Python. I am using Python 2.7.
import pysftp
srv = pysftp.Connection(host="www.destination.com", username="root",
password="password",log="./temp/pysftp.log")
srv.cd('public') #chdir to public
srv.put('C:\Users\XXX\Dropbox\test.txt') #upload file to nodejs/
# Closes the connection
srv.close()
The file did not appear on the server. However, no error message appeared. What is wrong with the code?
I have enabled logging. I discovered that the file is uploaded to the root folder and not under public folder. Seems like srv.cd('public') did not work.
I found the answer to my own question.
import pysftp
srv = pysftp.Connection(host="www.destination.com", username="root",
password="password",log="./temp/pysftp.log")
with srv.cd('public'): #chdir to public
srv.put('C:\Users\XXX\Dropbox\test.txt') #upload file to nodejs/
# Closes the connection
srv.close()
Put the srv.put inside with srv.cd
Do not use pysftp it's dead. Use Paramiko directly. See also pysftp vs. Paramiko.
The code with Paramiko will be pretty much the same, except for the initialization part.
import paramiko
with paramiko.SSHClient() as ssh:
ssh.load_system_host_keys()
ssh.connect(host, username=username, password=password)
sftp = ssh.open_sftp()
sftp.chdir('public')
sftp.put('C:\Users\XXX\Dropbox\test.txt', 'test.txt')
To answer the literal OP's question: the key point here is that pysftp Connection.cd works as a context manager (so its effect is discarded without with statement), while Paramiko SFTPClient.chdir does not.
import pysftp
with pysftp.Connection(host="www.destination.com", username="root",
password="password",log="./temp/pysftp.log") as sftp:
sftp.cwd('/root/public') # The full path
sftp.put('C:\Users\XXX\Dropbox\test.txt') # Upload the file
No sftp.close() is needed, because the connection is closed automatically at the end of the with-block
I did a minor change with cd to cwd
Syntax -
# sftp.put('/my/local/filename') # upload file to public/ on remote
# sftp.get('remote_file') # get a remote file

Python - ftplib.FTP_TLS Port

Can someone help me confirm the default port when using ftplib.FTP_TLS? We have opened port 990 and 21 but my script fails to connect.
import ftplib
session = ftplib.FTP_TLS('xxx.ftp.com','user','password')
file = open('Bkup.tar.gz','rb')
session.storbinary('STOR Bkup.tar.gz', file)
file.close()
session.quit()
Thank You!
You could try:
ftplib.FTP_TLS.port = 21
According to it's own documentation, as well as the spec, FTPS (or FTP over TLS) connects to port 21.
You appear to be missing a login clause to authenticate the session.
Try calling session.login() followed by session.prot_p() before attempting to store the binary.
This documentation can be found by using the help function or in the online documentation here.
I hope that helps.
Please don't modify the port directly. If you get a closer look at FTP_TLS super __init__ you can clearly see that if it's called with a host param connect gets automatically called with just the host as param so the port defaults to FTP_PORT which is 21.
A better approach would be to call FTP_TLS without any params and then manually call the connect method where you can specify host as well as port.
from ftplib import FTP_TLS
client = FTP_TLS()
client.connect(host="ftp.example.com", port=12121)
Oddly, the FTP_TLS object has no direct port parameter on the constructor like the FTP object does.
you can set the port prior to calling the constructor and that works.
ftplib.FTP_TLS.port=1234
ftplib.FTP_TLS( 'ftphost.domain.tld', 'user', 'password' )

SFTP using ftplib

I need to download a file from a host using SFTP.
Do you know if is it possible to do that using Python ftplib?
I saw an example here, but when I try to connect I receive EOFError.
I tried this code:
import ftplib
ftp = ftplib.FTP()
ftp.connect( "1.2.3.4", "22" )
This method returns with an error after long time so I cannot perform a call to login.
I cannot try the constructor FTP([host[, user[, passwd[, acct[, timeout]]]]]) because
my port is 22 but ftplib default is 21.
If I follow the example
ftp = ftplib.FTP("1.2.3.4")
ftp = ftplib.FTP("1.2.3.4","22")
I receive a connection refused so I cannot enter any username password. Can you help me? Thank you very much
As the question you linked to states, ftplib doesn't support SFTP (which is a transfer protocol over SSH and has nothing to do with FTPS, FTP over SSL). Use the recommended Paramiko instead.
