Ssh套接字已关闭。想要Linux Box的交互式Ssh shell自动化。

import paramiko

ssh = paramiko.SSHClient()

ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
##Creating Ssh Session

ssh.connect("gfr4123408", port=22, username='rstrusr',password='Password')

stdin,stdout,stderr = ssh.exec_command('symcfg -lockbox reset -ssv')

#Here it asks for password and i want to write password below

stdin.write("Password")

stdin.write('\n')

stdin.flush()

output=stdout.readlines()

print(output)

我得到以下错误：

Traceback (most recent call last):   File "<pyshell#24>", line 1, in
<module>
    stdin.write('password')   File "C:\Users\venkar2\AppData\Local\Programs\Python\Python36\lib\site-packages\paramiko\file.py",

    raise socket.error('Socket is closed') OSError: Socket is closed

我必须为200多台设备进行配置，如何解决此问题？
