python下paramiko模块学习之一：ssh登录和执行命令

    最近闲着学习python，看到有个paramiko模块，貌似很强大，学着写了个一个小程序，可以直接在window下登录到linux，执行并返回执行结果。

    下面直接贴代码：

 

#!/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()

下面看下效果，呵呵：
