I am trying to connect to SFTP server using Paramiko in Python 2.7.
Here is my code:
# Python 2.7
# -*- coding: utf-8 -*-
import paramiko
# Connect to Server
ssh = paramiko.SSHClient()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
ssh.connect('ip_address',port = 22,username='user',password='password')
I get this error:
Traceback (most recent call last):
File "C:\Python27\lib\socket.py", line 228, in meth
return getattr(self._sock,name)(*args)
socket.error: [Errno 10061] No connection could be made because the target machine actively refused it
I have searched this issue in different places but still haven't found any decisions.
Port and other credentials to this server are correct. That's for sure, because I can connect to it through SFTP client FileZilla.
The code above is working from my personal machine, but it doesn't work from my corporate computer. That's why I think it's because of proxy.
Do you have any suggestions how can I go through proxy in this case?
I already have had environment variables
http_proxy='http://username:password#proxy:port'
https_proxy='https://username:password#proxy:port'
Any help would be valuable!
The Paramiko itself does not implement proxies.
You have to provide a custom implementation of a "socket" via the sock parameter of the connect method.
The httplib.HTTPConnection can be used as such implementation for HTTP proxies.
For some examples, see:

I thought I'd share this puzzler. . . I've been successfully using 'plain' paramiko for SFTP for years (but always to port 22). I had a requirement to do SFTP over a non-standard port (115) and I could not establish a connection.
Moving to pysftp solved the problem, but as best I can tell, pysftp is built ontop of the paramiko libraries.
'plain' paramiko code:
import paramiko
transport = paramiko.Transport((hostname,115))
transport.connect(username=user,password=passwd)
sftp = paramiko.SFTPClient.from_transport(transport)
The error thrown:
File "c:\python27\lib\site-packages\paramiko\transport.py", line 311, in __init__
'Unable to connect to %s: %s' % (hostname, reason))
paramiko.ssh_exception.SSHException: Unable to connect to XXX.XXX.XXX.XXX: [Errno 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
Moving to pysftp has solved the problem, but pysftp has a paramiko dependency
sftp = pysftp.Connection(hostname,username=user,password=passwd,port=115)
Insights are appreciated
I want to transfer a file from a local server (that'll contain the code and file) to a remote server preferably using ssh. Here's the code:
import paramiko
ssh = paramiko.SSHClient()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
ssh.connect('Servername', port = 135, username='username', password='password')
print "connected successfully!"
sftp = ssh.open_sftp()
print sftp
sftp.put('G:\TestDocument.txt','G:\TestDocument.txt' )
sftp.close()
print "copied successfully!"
ssh.close()
But I get this error:
No handlers could be found for logger "paramiko.transport"
Traceback (most recent call last): File
"C:/Python27/testtransfer.py", line 5, in
ssh.connect('Servername', port = 135, username='username', password='password') File

t.start_client(timeout=timeout) File "C:\Python27\lib\site-packages\paramiko\transport.py", line 545, in
start_client
raise e SSHException: Error reading SSH protocol banner
Can you tell me why am I receiving this error? I have purposely used port 135 because port 22 is closed on the target server and 135 (among others) is open.
You can even suggest some other way in which I can transfer files from one server to another using Python.
SSHException: Error reading SSH protocol banner
the error usually means the remote service was not a ssh service. try to make sure the service on port 135 is actually ssh.
And what's the OS on your server? Windows? if so you may need to setup a 3rd-part ssh server on your server. In my opinion if you need to copy files from windows to windows ftp is a much simpler solution. python has a built-in lib ftplib.
I wrote a generic script on Python that supports Windows and Unix ssh connection from Unix.
When I try Unix command from Unix to create dir in Windows, I get exit 53
/usr/bin/ssh2 --password pass -l admin ip_address mkdir "C:\Temp\ALEX_TEST_EX" &
When I write only /usr/bin/ssh2 --password pass -l admin ip_address, it is Ok. I login to Windows
When I try C:\Temp\ALEX_TEST_EX on this machine manually it is also Ok.
What is problem?
I also try to use with Python ssh2 command like
import paramiko
ssh = paramiko.SSHClient()
ssh.connect("ip_address", username="admin", password="pass")
but I get exceptions
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/python3.5/site-packages/paramiko/client.py", line 402, in connect
self, server_hostkey_name, server_key
File "/python3.5/site-packages/paramiko/client.py", line 768, in missing_host_key
'Server {!r} not found in known_hosts'.format(hostname)
paramiko.ssh_exception.SSHException: Server 'X.Y.Z.W' not found in known_hosts
You have not configued the client machine to allow you to know the server you are trying to connect to. You can either configure the client, or as a work around you can set the MissingHostKeyPolicy on paramiko like:
Code:
To warn when host not in known hosts:
ssh.set_missing_host_key_policy(paramiko.WarningPolicy)
To auto add host to know hosts:
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy)
Full Code:
import paramiko
ssh = paramiko.SSHClient()
ssh.set_missing_host_key_policy(paramiko.WarningPolicy)
ssh.connect("localhost", username="admin", password="pass")
So, I have this program I made that connects to another computer (which is a linux machine) through SSH in python with the help of the library paramiko. I've made all the development on my ubuntu machine at work and it runs just fine on my home gentoo setup. I've been asked to make it work on a windows machine, and I get errors I cannot quite figure out what they mean to be honest, I'm not really confortable in windows environments.
The code is the following :
self.ssh = paramiko.SSHClient()
self.ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
self.ssh.connect(
hostname=self.address,
username=self.username,
password=self.password
)
self.shell = self.ssh.invoke_shell(width=self.shell_width, height=self.shell_height)
self.transport = paramiko.Transport((self.address, self.port))
self.transport.connect(
username=self.username,
password=self.password
)
self.sftp = paramiko.SFTPClient.from_transport(self.transport)
So basically I have an interactive SSH shell I use to issue commands, and an SFTP connection as well to retrieve the files I created from the SSH session.
When running this code on windows :
Traceback (most recent call last):
File "C:/Users/labor/PycharmProjects/OPSS/OPSS.py", line 9, in <module>
shell.run("uptime")
File "C:\Python27\lib\site-packages\spur\ssh.py", line 162, in run

raise self._connection_error(error)
spur.ssh.ConnectionError: Error creating SSH connection
Original error: [Errno 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 don't really know what the system is trying to tell me when it says the party failed to respond because I can connect to it just fine with WinSCP and PuTTY from windows (which are the two programs I used to test both SSH and SFTP).
As you can tell I'm using PyCharm as my IDE, and I installed paramiko using its package manager on windows (on my linux machines I used pip).
Does anyone know what is happening ? And how can I make it work ? Thanks !
Hi I have this sample path "\10.81.67.162" which is a remote server (windows OS)
I want to be able to transfer files (local) to the remote server using paramiko in python.
I can make it work if the server is in linux.
This is my sample code
import paramiko
import base64
username = 'username'
password = 'password'
host = "10.81.67.162"
port = 22
transport = paramiko.Transport((host,port))
transport.connect(username = username, password = password)
stfp = paramiko.SFTPClient.from_transport(transport)
But having thhis error in windows:
Traceback (most recent call last):
File "ssh.py", line 9, in <module>
transport = paramiko.Transport((host,port))
File "build\bdist.win32\egg\paramiko\transport.py", line 289, in __init__
File "C:\Python27\lib\socket.py", line 224, in meth
return getattr(self._sock,name)(*args)
socket.error: [Errno 10061] No connection could be made because the target machi
ne actively refused it
Python version 2.7
Paramiko version 1.7.5
Thanks!
There is no SSH server running on Windows. Thats why you are not able to connect.
Windows doesn't support SSH natively. You need to install third-party SSH server on your remote windows hosts like cygwin, bitwise ssh or freeSSHD.
Or if you are interested to run only commands on windows host then you can use winrm protocol which is natively supported by Windows. For this you need a python library pywinrm. I have used this and works fine:
https://github.com/diyan/pywinrm
If you're trying to connect to a network drive, you can use win_unc:
import os
from win_unc import UncCredentials, UncDirectory, UncDirectoryConnection
creds = UncCredentials('USERNAME', 'PASSWORD')
unc = UncDirectory(r'\\<computername>\c$', creds)
conn = UncDirectoryConnection(unc)
conn.connect()
print list(os.listdir(r'\\<computer_name>\c$\<folder>'))
