Connecting to an Ubuntu Server with Python

Question

My goal is to have a basic FTP program written in Python. First, I need to gain more knowledge. My question is, how can I connect to an Ubuntu Server (hosted via VirtualBox) using Python?

I have tried using the page on the official Python website but I get an error saying socket.error: [Errno 61] Connection refused when using this

from ftplib import FTP
ftp = FTP('jordan@10.0.0.12')

This is the output I get when using ftp - FTP('10.0.0.12')

Traceback (most recent call last): File "", line 1, in File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/ftplib.py", line 120, in init self.connect(host) File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/ftplib.py", line 135, in connect self.sock = socket.create_connection((self.host, self.port), self.timeout) File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/socket.py", line 575, in create_connection raise err socket.error: [Errno 61] Connection refused

I can use an FTP program such as Transmit (the same port and on SFTP) on the same machine and it works fine.

What happens when you try to ftp from the command line the same way? `ftp jordan@10.0.0.12` — mVChr, Dec 26 '16 at 21:39
When using the command `ftp jordan@10.0.0.12` from Terminal I get the same error. — Jordan Baron, Dec 26 '16 at 21:46
ok so it fails from terminal but works from Transmit right? there may be some default settings, such as passive, or something else, in Transmit that makes it work. — Jean-François Fabre, Dec 26 '16 at 21:52
Do you use Transmit on the same machine as the Python code and command-line `ftp`? — Martin Prikryl, Dec 26 '16 at 21:57
Is Transmit using the same port? Is it FTP or SFTP? `PASV` should be set by default in `ftplib`. Maybe try setting `ftp.set_debuglevel(2)` so we can get some more information? — Jeremy, Dec 26 '16 at 22:19
If `ftp.set_debuglevel(2)` is set before the login attempt, it should automatically output when you `ftp.login()` — Jeremy, Dec 26 '16 at 22:24
In looking at the docs, FTP accepts the user as a separate argument. Try it without `'jordan@'`. If you are able to connect, pass the username as a separate argument. e.g.: `ftp = FTP('10.0.0.12', 'jordan')` — Jeremy, Dec 26 '16 at 22:31
This is with debuglevel(2)? There should be more information. — Jeremy, Dec 26 '16 at 22:34
Are you saying Transmit connects via SFTP, does it connect via FTP? — Jeremy, Dec 26 '16 at 22:41
Transmit does not connect via FTP: `Error -157: invalid reply from server` Also, please email me at jordanmbaron12@gmail.com so we don't have a super long thread. — Jordan Baron, Dec 26 '16 at 22:42
Python's `ftplib` does not support `SFTP`. It can connect via `FTP with TLS`. You either need to run an `FTP` server on the Ubuntu box or use a solution such as `Paramiko` or `pysftp` to connect to the server in question. http://stackoverflow.com/questions/432385/sftp-in-python-platform-independent — Jeremy, Dec 26 '16 at 22:45

Python's ftplib does not support SFTP, so using PySFTP would work.
