Secure Copy File From Remote Server Via Scp And Os Module In Python

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 ' + hostname + ' scp ' + filepath + '

Solution 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:

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

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