Secure Copy File from remote server via scp and os module in Python

Question

I\'m pretty new to Python and programming. I\'m trying to copy a file between two computers via a python script. However the code

os.system(\"ssh \" + hostna         


        

Answer 1

I think the easiest (to avoid having to enter a password) and most secure way to go about this is to first set public/private key authentication. Once that is done, and you can log in to the remote system by doing ssh user@hostname, the following bash command would do the trick:

scp some/complete/path/to/file user@remote_system:some/remote/path

The corresponding Python code would be:

import subprocess

filepath = "some/complete/path/to/file"
hostname = "user@remote_system"
remote_path = "some/remote/path"

subprocess.call(['scp', filepath, ':'.join([hostname,remote_path])])
