paramiko很好用

最近常用pramiko ，都成模式了。

#!/usr/bin/env python
# -*- coding: utf-8 -*-
import paramiko

host=your_ip
username="root"
password=your_pass
SHOW_CWD='pwd'

try:
    client = paramiko.SSHClient()
    client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
    client.connect(host, username=username,password=password, timeout=30)
    (stdin, stdout, stderr) = client.exec_command(SHOW_CWD)
    rc = stdout.channel.recv_exit_status()
    output = stdout.read().decode()
    if rc==0:
        print(output)
except Exception as e:
    print("%s excepion happenend ",e)
finally:
    client.close()
