python paramiko实现SSH 一台设备一条命令

代码：

import paramiko
import time



host = 'xxx'
username = 'xxx'
password = 'xxx'
port = 22

command = 'uname -a \n'

ssh = paramiko.SSHClient()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
ssh.connect(hostname=host,username=username, password=password, port=port, look_for_keys=False, allow_agent=False)

stdin, stdout, stderr = ssh.exec_command(command)
output = stdout.readlines()
print(' '.join(map(str, output)))
