How do I transfer SPECIFICALLY an Image file to from client to server using Python Paramiko [duplicate]

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)

Uploading file using Paramiko in Python seemingly works, but the file cannot be found on the server

I am new to Python and sorry for my bad english.
I'm trying to save a file "toto.txt" from my HDD "d:" to my Synology NAS.
So I'll use paramiko for this, here is the code :
import paramiko
import os
ip_address = "my nas ip"
username = "my username"
password = "mypass"
utilisateur = os.getenv("USERNAME") // to get Windows username
remote_path = f"{utilisateur}/test.txt" // the file downloaded
local_path = "d:/toto.txt" //the file stored on my pc
ssh_client = paramiko.SSHClient()
ssh_client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
ssh_client.connect(hostname=ip_address,username=username,password=password)
print("Connexion OK >", ip_address)
stdin, stdout, stderr = ssh_client.exec_command(f'mkdir {utilisateur}') //creating folder for the
user
sftp = ssh_client.open_sftp()
sftp.put(local_path,remote_path) // trying to send the file
sftp.close()
ssh_client.close()
i am not getting error but nothing is happening.
The folder is successful created but no file is sending in it.
Have someone an idea?
thanks a lot

If Paramiko does not throw any error, the upload was successful. The file just possibly ended in different location than you wanted/than you look to.
At least for a test, if not permanently, try an absolute absolute path. Make no guesses, use the exact path you see in your GUI SFTP client.
Another possibility is that the server automatically processes the uploaded file somehow and moves it away.

Python Script Uploading files via FTP

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"

Python 2.5 script to connect to FTP and download file

I am sure this has been resolved before but I cannot seem to find a similar Q&A (newbie)
Using Windows XP and Python 2.5, I m trying to use a script to connect to an FTP server and dowload files. It should be simple but following the instructions of similar scripts I get the errors:
ftp.login('USERNAME')
File "C:\Python25\lib\ftplib.py", line 373, in login
if resp[0] == '3': resp = self.sendcmd('PASS ' + passwd)
File "C:\Python25\lib\ftplib.py", line 241, in sendcmd
return self.getresp()
File "C:\Python25\lib\ftplib.py", line 216, in getresp
raise error_perm, resp
error_perm: 530 User USERNAME cannot log in.
The script I use is:
def handleDownload(block):
file.write(block)
print ".",
# Create an instance of the FTP object
# FTP('hostname', 'username', 'password')
ftp = FTP('servername')
print 'ftplib example'
# Log in to the server
print 'Logging in.'
# You can specify username and password here if you like:
ftp.login('USERNAME', 'password')
#print ftp.login()
# This is the directory
directory = '/GIS/test/data'
# Change to that directory.
print 'Changing to ' + directory
ftp.cwd(directory)
# Print the contents of the directory
ftp.retrlines('LIST')
I appreciate this might be a trivial question, but if anyone can provide some insights it would be very helpful!
Thanks, S

I can't understand which library are you using. Python standard urllib2 is sufficient:
import urllib2, shutil
ftpfile = urllib2.urlopen("ftp://host.example.com/path/to/file")
localfile = open("/tmp/downloaded", "wb")
shutil.copyfileobj(ftpfile, localfile)
If you need to login (anonymous login isn't sufficient), then specify the credentials inside the url:
urllib2.urlopen("ftp://user:password#host.example.com/rest/of/the/url")

ftp.login('USERNAME', 'password')
Replace this with real data. According to the error you are trying to login as "USERNAME" with the password "password" which obviously won't work.
Also, replace servername in ftp = FTP('servername')
with the hostname of the server you want to connect to.

the first trivial check would be to open an interactive session (i.e. ftp yourself to this server with the same credentials), to be sure that this is not a permission issue..
Another source of failure, you might need to give your username as domain\username when connecting to a MS ftp server.
Maybe that helps ?
