Python's Paramiko module

Paramiko is a module written in the Python language that follows the SSH2 protocol and supports the connection of remote servers in a way that is encrypted and authenticated.

All Python-supported platforms, such as Linux, Solaris, BSD, MacOS X, Windows, and so on, are supported by the use of Python, which can run across platforms, so Paramiko Paramiko is one of the best tools when you need to use SSH to connect to another platform from one platform and perform a series of operations.

First, install the Paramiko module

[[Email protected] ~]# pip install Paramiko

Second, remote connection

1, Method one

Import paramikossh = Paramiko. Sshclient () # Creates a client connection to the service-side object Ssh.set_missing_host_key_policy (Paramiko. Autoaddpolicy ()) # Allow connections to hosts that are not in the Know_hosts file Ssh.connect (ip,port,username,password) # Connect to a remote server

2. Method Two

Import paramikotus = (IP, port) t = Paramiko. Transport (TUS) # Create Transfer Object T.connect (Username=self.username, Password=self.password)

Third, File transfer

tus = (IP, port) t = Paramiko. Transport (TUS) t.connect (Username=username, password=password) sftp = Paramiko. Sftpclient.from_transport (t) # Create download Transfer object Sftp.get (LocalPath, remotepath) # download Sftp.put (LocalPath, Remotepa TH) # upload T.close ()
