I am writing a program using pysftp, and it wants to verify the SSH host Key against C:\Users\JohnCalvin\.ssh\known_hosts
.
Using PuTTY, the terminal program is saving it to the Registry [HKEY_CURRENT_USER\Software\SimonTatham\PuTTY\SshHostKeys]
.
How do I reconcile the difference between pysftp and PuTTY?
My code is:
import pysftp as sftp
def push_file_to_server():
s = sftp.Connection(host='138.99.99.129', username='root', password='*********')
local_path = "testme.txt"
remote_path = "/home/testme.txt"
s.put(local_path, remote_path)
s.close()
push_file_to_server()
The Error Response I am receiving is:
E:\Program Files (x86)\Anaconda3\lib\site-packages\pysftp__init__.py:61: UserWarning:
