I have the following issue... i need to connect to sftp(vsftpd) through python script, upload a file and download it. So far i have created ftp server with vsftpd but i cannot connect. If i use the terminal(ftp localhost) i can log in without any problems. Please advise how i should proceed.
Here is my python script:
http://codepaste.net/omysxu
and here is the config file of vsftpd:
http://codepaste.net/1qrrdf
The thing that i am trying to do is.. set up a ftp server, then i should have 2 scripts(or 1) which will have to upload file via ssh then download it in another dir.
vsftpd is a FTP server and can not be accessed with the SFTP protocol. FTP, SFTP and FTPS are often confused:
FTP = file transfer protocol (RFC959) - supported by vsftpd
FTPS = extension for using TLS with FTP (RFC4217) - supported by vsftpd
SFTP = file transfer using the SSH protocol - not supported by vsftpd, you need SSH for this.

I want to copy a file from my SFTP server to local computer. However, when I run my code, it didn't show any error while I still cannot find my file on local computer. My code like that:
import paramiko
host_name ='10.110.100.8'
user_name = 'abc'
password ='xyz'
port = 22
remote_dir_name ='/data/.../PMC1087887_00003.jpg'
local_dir_name = 'D:\..\pred.jpg'
t = paramiko.Transport((host_name, port))
t.connect(username=user_name, password=password)
sftp = paramiko.SFTPClient.from_transport(t)
sftp.get(remote_dir_name,local_dir_name)
I have found the main problem. If I run my code in local in VS Code, it works. But when I login in my server by SSH in VS Code, and run my code on server, I found that my file appeared in current code folder (for example /home/.../D:\..\pred.jpg) and its name is D:\..\pred.jpg. How to solve this problem if I want to run code on server and download file to local?
If you call SFTPClient.get on the server, it will, as any other file manipulation API, work with files on the server.
There's no way to make remote Python script directly work with files on your local machine.
You would have to use some API to push the files to your local machine. But for that, your local machine would have to implement the API. For example, you can run an SFTP server on the local machine and "upload" the files to it.
I want to create a directory in my remote system using python script or by socket programming. I have remote system's Username, password and IP address. I am able to do this in my local machine but not in remote. Please help!
Download Putty then connect to remote system) and in terminal write mkdir foldername
To create a directory on a remote machine, you will have to first connect to it.Telnet and SSH and SSH is used to connect to remote machines. Obviously TELNET or SSH service should be running on the remote machine, otherwise you won't be able to connect.Since in case of Telnet,data is transfered in plain text, it's better to use SSH protocol.
Once connected to the remote machine using SSH, you will be able to execute commands on the remote machine.
Now since you want to do everything in Python, you will have to write a complete SSH client in Python. Which is greate for learning, because you will learn about socket programming and cryptography.
If you are in a hurry, you can use a good SSH library.
If you are getting network connection error, please check whether SSH is installed in the remote machine or not. If yes, then check firewall settings.
I am using paramiko to create a SFTP server. I have succeeded in uploading and downloading files to and from server on client request.But, I need to send a file from server to client whenever I need without client request. So, instead of breaking my head on making server send a file to client I want to make both machines act as both server and client in different ports so that when I need to send a file from machine A to B I can just Upload it to the SFTP server running on that port. Is this hypothesis possible?
You already know that you cannot send a file from an server to a client:
Can I send a file from SFTP Server to the Client without any request from it?
(The question on Server Fault has been deleted)
To answer your port question:
You do not care about client's port. It is automatically assigned to any available port, without you ever needing to know its value. In general, that's true for any TCP/IP connection, not only SFTP.
So you can just run SFTP server on both machines on the standard port 22. And use your client code on the other machine to connect to it.
I am executing a Python script on my Linux server that uses pysftp to connect to another server in order to read files that are sitting in a directory of that remote server. When I run the script, it fails out while connecting to the remote server and creates a text file with the title: 'This service allows sftp connections only.'
This file is created inside my project directory. Below is the part of my code that is failing:
def sftp_get_file(sftp_host, sftp_username):
with pysftp.Connection(sftp_host, sftp_username) as sftp:
# transfer file from remote to local
sftp.get(remote_file, local_file)
Code is very simple and works when I've tested it using my local server as the remote server. When I tested it in the new environment by actually depending on SFTP, then it failed. Any suggestions? Is pysftp using SSH at some point when it should be using only SFTP?
Turns out the problem was due to me performing sftp.execute('ls') a couple lines down in the script. The server I was remoting onto only supported sftp commands and that command was forbidden.
I have been able to use ssh and issue command in the remote server. Now I want to scp files from the remote server but that just seems like its impossible. I'm totally new to python and Paramiko. The error is permission denied in my local directory of darn windows. The files are supposed to come from the Mac. Any other really really simple example I can use to scp files from a remote Linux machine to my local Windows machine?
import paramiko
hostname = '192.xx.1.xx'
password = 'pop123'
username = "husbad2"
port = 22
mypath='C:\\Users\\handsonexpert\\Documents'
remotepath='/Users/ihussain/testdir/file3.txt'
t = paramiko.Transport((hostname, 22))
t.connect(username=username, password=password)
sftp = paramiko.SFTPClient.from_transport(t)
sftp.put(mypath, remotepath)
To retrieve files from a remote host into a local directory:
......
localpath='C:\\Users\\handsonexpert\\Documents\\file3.txt'
remotepath='/Users/ihussain/testdir/file3.txt'
......
sftp.get(remotepath, localpath)
You're not using scp here, but SFTP (SFTPClient).
If you're set on using scp, maybe take a look at this paramiko scp client, there is an example of how to use it here.
Aside, out of general security interests and programming style, don't hard code your password and user credentials, and especially never publish them in a public forum like SO. We don't need them and you don't need to post them.
