Aim: I am trying to use SFTP through Paramiko in Python to upload files on server pc.
What I've done: To test that functionality, I am using my localhost (127.0.0.1) IP. To achieve that I created the following code with the help of Stack Overflow suggestions.
Problem: The moment I run this code and enter the file name, I get the "IOError : Failure", despite handling that error. Here's a snapshot of the error:
import paramiko as pk
import os
userName = "sk"
ip = "127.0.0.1"
pwd = "1234"
client=""
try:
client = pk.SSHClient()
client.set_missing_host_key_policy(pk.AutoAddPolicy())
client.connect(hostname=ip, port=22, username=userName, password=pwd)
print '\nConnection Successful!'
# This exception takes care of Authentication error& exceptions
except pk.AuthenticationException:
print 'ERROR : Authentication failed because of irrelevant details!'
# This exception will take care of the rest of the error& exceptions
except:
print 'ERROR : Could not connect to %s.'%ip
local_path = '/home/sk'
remote_path = '/home/%s/Desktop'%userName
#File Upload
file_name = raw_input('Enter the name of the file to upload :')
local_path = os.path.join(local_path, file_name)
ftp_client = client.open_sftp()
try:
ftp_client.chdir(remote_path) #Test if remote path exists
except IOError:
ftp_client.mkdir(remote_path) #Create remote path
ftp_client.chdir(remote_path)
ftp_client.put(local_path, '.') #At this point, you are in remote_path in either case
ftp_client.close()
client.close()
Can you point out where's the problem and the method to resolve it?
Thanks in advance!
The second argument of SFTPClient.put (remotepath) is path to a file, not a folder.
So use file_name instead of '.':
ftp_client.put(local_path, file_name)
... assuming you are already in remote_path, as you call .chdir earlier.
To avoid a need for .chdir, you can use an absolute path:
ftp_client.put(local_path, remote_path + '/' + file_name)

I am trying to use Paramiko to get a log file from my Raspberry Pi:
import paramiko
paramiko.util.log_to_file("paramiko.log")
# Open a transport
host, port = RECV_IP_ADDRESS, 22
transport = paramiko.Transport((host, port))
# Auth
username, password = "pi", "raspberry"
transport.connect(None, username, password)
# Go!
sftp = paramiko.SFTPClient.from_transport(transport)
# Download
filepath = "/"
localpath = "/home/pi/Code/log.txt"
sftp.get(filepath, localpath)
# Close
if sftp: sftp.close()
if transport: transport.close()
However when I run this program I get a file not found error:
FileNotFoundError: [Errno 2] No such file or directory: '/home/pi/Code/log.txt'
Clearly the file is here
po#raspberrypi:~/Code $ pwd
/home/pi/Code
po#raspberrypi:~/Code $ ls
a.out log.txt test.c
po#raspberrypi:~/Code $ _
(terminal screenshot)
But the program can't seem to find it.
I had thought that perhaps the connection had died. I tried a suggestion found here:
Check if paramiko ssh connection is still alive
transport.send_ignore()
Did not yield an error.
I am new to Paramiko. Do I need to run something on the Pi in order for this to work? Is it not simply a wrapper for SFTP/SSH?
Your immediate problem is that you have the parameters of SFTPClient.get the other way around (you even have the variables named wrong, the localpath should obviously be remotepath). So Paramiko tries to create a local file with the path of your remote file. As /home/pi/Code does not exist on your local (target) machine, you get local FileNotFoundError error.
Once you correct this, you will have another problem. The localpath path argument of SFTPClient.get needs to be path to the file, not only path to the target directory. See Python Paramiko, PermissionError: [Errno 13] Permission denied when get files from remote server.
So like this:
localpath = "/log.txt"
remotepath = "/home/pi/Code/log.txt"
sftp.get(remotepath, localpath)
You messed up the order of the parameters. Or use '//' for the file path
I need to put multiple file on SFTP server. But I am confused here of how to loop through them if path to SFTP requires file name and extension? Which in my case it will be dynamic.
# sftp path where file should be delivered
sftp_path = fr'/Incoming/{filename_PRE}.csv' # if not supply filename it will give permission error. Why?
## push file to sftp server
def push_file_sftp():
try:
## HostKey
keydata = b"""AAAABBB2222888555="""
key = paramiko.RSAKey(data=decodebytes(keydata))
cnopts = sftp.CnOpts()
cnopts.hostkeys.add('hostname', 'ssh-rsa', key)
## Credentials
s = sftp.Connection(host='hostname', username='username', password='psswd',cnopts=cnopts)
# how can I put 2 files here?
s.put(filepath_PRE, sftp_path)
s.close()
except Exception as e:
print(str(e))
push_file_sftp()
So just use update the remote path with the correct filename:
sftp_path = '/Incoming'
filepath_PRE = "file1"
s.put(filepath_PRE, sftp_path + "/" + filepath_PRE + ".csv")
filepath_PRE = "file2"
s.put(filepath_PRE, sftp_path + "/" + filepath_PRE + ".csv")
I am working on a project that requires us to upload a vile via SFTP to a remote server, and we are having troubles doing this. We tried following this youtube guide, but we are having some issues.
We are getting a "no such file" error when we run the script, and we know for sure that the file exists and that we have given the python script the right name and location for the file.
This is the script as we have it right now:
import pysftp as sftp
def sftpTry():
try:
s = sftp.Connection(host='babbage.cs.missouri.edu', username ='<username>', password = '<password>')
remotepath = '~it3001s14grp1/videos/newVideo/new.avi'
#localpath = '/etc/motion/capture/hello.txt'
localpath = '/etc/motion/capture/06--2014-05-15---16-16-25.avi'
s.put(localpath, remotepath)
s.close()
except Exception, e:
print str(e)
sftpTry();
You should begin your remote path with a forward slash "/". Also, check the directory you are specifying in the remotepath. You should try to do a pwd in the directory when you login into the server (say using ssh). The remote-path should be specified exactly like that.
Although you do have the filename name in the remote path, it would throw an error if you specify just the folder's name.
Another tip would be to use getpass instead of hard-coding the password:
passwd = getpass.getpass()
s = sftp.Connection(host='<host>', username = '<username>', password = passwd)
I would like to make a script to upload a file to FTP.
How would the login system work? I'm looking for something like this:
ftp.login=(mylogin)
ftp.pass=(mypass)
And any other sign in credentials.
Use ftplib, you can write it like this:
import ftplib
session = ftplib.FTP('server.address.com','USERNAME','PASSWORD')
file = open('kitten.jpg','rb') # file to send
session.storbinary('STOR kitten.jpg', file) # send the file
file.close() # close file and FTP
session.quit()
Use ftplib.FTP_TLS instead if you FTP host requires TLS.
To retrieve it, you can use urllib.retrieve:
import urllib
urllib.urlretrieve('ftp://server/path/to/file', 'file')
EDIT:
To find out the current directory, use FTP.pwd():
FTP.pwd(): Return the pathname of the current directory on the server.
To change the directory, use FTP.cwd(pathname):
FTP.cwd(pathname): Set the current directory on the server.
ftplib now supports context managers so I guess it can be made even easier
from ftplib import FTP
from pathlib import Path
file_path = Path('kitten.jpg')
with FTP('server.address.com', 'USER', 'PWD') as ftp, open(file_path, 'rb') as file:
ftp.storbinary(f'STOR {file_path.name}', file)
No need to close the file or the session
You will most likely want to use the ftplib module for python
import ftplib
ftp = ftplib.FTP()
host = "ftp.site.uk"
port = 21
ftp.connect(host, port)
print (ftp.getwelcome())
try:
print ("Logging in...")
ftp.login("yourusername", "yourpassword")
except:
"failed to login"
This logs you into an FTP server. What you do from there is up to you. Your question doesnt indicate any other operations that really need doing.
Try this:
#!/usr/bin/env python
import os
import paramiko
ssh = paramiko.SSHClient()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
ssh.connect('hostname', username="username", password="password")
sftp = ssh.open_sftp()
localpath = '/home/e100075/python/ss.txt'
remotepath = '/home/developers/screenshots/ss.txt'
sftp.put(localpath, remotepath)
sftp.close()
ssh.close()
To avoid getting the encryption error you can also try out below commands
ftp = ftplib.FTP_TLS("ftps.dummy.com")
ftp.login("username", "password")
ftp.prot_p()
file = open("filename", "rb")
ftp.storbinary("STOR filename", file)
file.close()
ftp.close()
ftp.prot_p() ensure that your connections are encrypted
I just answered a similar question here
IMHO, if your FTP server is able to communicate with Fabric please us Fabric. It is far better than doing raw ftp.
I have an FTP account from dotgeek.com so I am not sure if this will work for other FTP accounts.
#!/usr/bin/python
from fabric.api import run, env, sudo, put
env.user = 'username'
env.hosts = ['ftp_host_name',] # such as ftp.google.com
def copy():
# assuming i have wong_8066.zip in the same directory as this script
put('wong_8066.zip', '/www/public/wong_8066.zip')
save the file as fabfile.py and run fab copy locally.
yeukhon#yeukhon-P5E-VM-DO:~$ fab copy2
[1.ai] Executing task 'copy2'
[1.ai] Login password:
[1.ai] put: wong_8066.zip -> /www/public/wong_8066.zip
Done.
Disconnecting from 1.ai... done.
Once again, if you don't want to input password all the time, just add
env.password = 'my_password'
You can use the below function. I haven't tested it yet, but it should work fine. Remember the destination is a directory path where as source is complete file path.
import ftplib
import os
def uploadFileFTP(sourceFilePath, destinationDirectory, server, username, password):
myFTP = ftplib.FTP(server, username, password)
if destinationDirectory in [name for name, data in list(remote.mlsd())]:
print "Destination Directory does not exist. Creating it first"
myFTP.mkd(destinationDirectory)
# Changing Working Directory
myFTP.cwd(destinationDirectory)
if os.path.isfile(sourceFilePath):
fh = open(sourceFilePath, 'rb')
myFTP.storbinary('STOR %s' % f, fh)
fh.close()
else:
print "Source File does not exist"
