Getting Started with the Paramiko module in python one: SSH login and execute command

Recently busy learning Python, see a Paramiko module, seemingly very powerful, learn to write a small program, you can log on to Linux directly under Windows, execute and return execution results.

The following is directly attached to the code:

#!/usr/bin/env python    
import paramiko    
        
#hostname = ' 192.168.0.102 '    
hostname= ' 172.28.102.250 '
Username= ' root '
password= ' abc '
        
#port =22    
if __name__== ' __main__ ':    
        paramiko.util.log_to_file (' Paramiko.log ')    
        S=paramiko. Sshclient ()    
        #s. Load_system_host_keys () S.set_missing_host_key_policy () (    
        Paramiko. Autoaddpolicy ())    
        s.connect (hostname = hostname,username=username, Password=password)    
        stdin,stdout, Stderr=s.exec_command (' ifconfig;free;df-h ')    
        print stdout.read ()    
        s.close ()

Below look at the effect, hehe:

The code is very simple, we are interested, you can experiment, hope to your study and work helpful.
