[Python] Using SFTP and RSA keys to remotely copy files

If the two servers use the RSA key-free password-based login method, you can first find the corresponding directory of the RSA key (such as find/-name id_rsa or locate id_rsa ),

The following code uses the paramiko module in Python to implement the SCP function:

Def scp_by_key (host_ip, host_port, remote_path, local_path, username, pkey_path): Try: Key = paramiko. rsakey. from_private_key_file (pkey_path) t = paramiko. transport (host_ip, host_port) T. connect (username = username, pkey = Key) SFTP = paramiko. sftpclient. from_transport (t) src = remote_path des = local_path SFTP. get (SRC, des) T. close () failed t exception as E: Print E

We can use this method as follows:

Scp_by_key ('2017. 168.0.33 ', 22,'/XX/XXX/a.txt ', 'xx/XXX/B .txt', 'xiaomo', '/home/xiaomo /. SSH/id_rsa ')

Is it easy to use? However, the premise is to have an RSA key... if you need a password, you only need to replace the pkey parameter with the password to pass in:

T = paramiko. Transport (host_ip, host_port) T. Connect (username = username, password = 'xxx ')
