很多运维人员平时进行维护linux/unix主机时候，无非通过ssh到相应主机 *** 作，那么一旦主机有成千上百台，那该如何应对，这时候我们需要批处理工具，基于python的工具有href="http://docs.ansible.com/" target="_blank">ansible、salt，而ansible的核心则是基于paramiko。
pip install paramiko或 easy_install paramiko
paramiko依赖第三方的Crypto，Ecdsa和pyhton-devel

参数：
@H_301_39@filename=None 指定本地公钥文件set_missing_host_key_policy():设置连接的远程主机没有本地主机密钥或HostKeys对象时的策略，目前支持三种,也就是参数只有三个。
参数：
@H_301_39@autoAddPolicy 自动添加主机名及主机密钥到本地的kNown_hosts，不依赖load_system_host_key的配置。即新建立ssh连接时不需要再输入yes或no进行确认@H_301_39@WarningPolicy 用于记录一个未知的主机密钥的python警告。并接受，功能上和autoAddPolicy类似，但是会提示是新连接@H_301_39@RejectPolicy 自动拒绝未知的主机名和密钥，依赖load_system_host_key的配置。此为默认选项 用法： set_missing_host_key_policy(paramiko.autoAddPolicy())
SFTPCLIEnt作为一个sftp的客户端对象，根据ssh传输协议的sftp会话，实现远程文件 *** 作，如上传、下载。
