Nested SSH with Paramiko and RSA key file

由 。_饼干妹妹 提交于 2020-12-08 04:52:30
问题 I am trying to nested SSH using Paramiko where I will connect to Server X from my local machine and from there I will connect to Server Y. Here to connect to Server X I am using username, password authentication and to connect to Server Y using username and RSA key. The thing is that the RSA key is hosted in System X which is used to connect Server Y. I was able to run the script successfully if I hosted the keyfile in my local PC and gave the local pc directory path to Paramiko SSH client.

问题 I am using Python's paramiko packet to keep an ssh-connection with an server : s = paramiko.SSHClient() s.set_missing_host_key_policy(paramiko.AutoAddPolicy()) s.connect("xxx.xxx.xxx.xxx",22,username=xxx,password='',timeout=4) I want to use this ssh-connection to transfer a file to ssh server, how can i do? Just like use scp a-file xxx@xxx.xxx.xxx.xxx:filepath command? 回答1: Try this: s = paramiko.SSHClient() s.set_missing_host_key_policy(paramiko.AutoAddPolicy()) s.connect("xxx.xxx.xxx.xxx"

自动化运维

自动化运维工具 需求：成百上千台机器，批量地执行某些命令、批量地升级某个服务。 Shell、expect脚本就可以实现自动化，但是需要我们自己手动编写脚本，效率低下、学习和维护成本很高。 主流自动化运维工具：Puppet、Saltstack、Ansible等。 Puppet 关于Puppet的介绍文章： https://blog.51cto.com/ixdba/1149055 Puppet是开源的基于Ruby的系统配置管理工具，基于C/S的部署架构。是一个为实现数据中心自动化管理而设计的配置管理软件，它使用跨平台语言规范，管理配置文件、用户、软件包、系统服务等。客户端默认每隔半小时会和服务器通信一次，确认是否有更新。当然也可以配置主动触发来强制客户端更新。这样就把日常的系统管理任务代码化了，代码化的好处是可以分享，保存，避免重复劳动，也可以快速恢复以及快速的大规模部署服务器。 Saltstack Saltstack使用Python开发，是一个非常简单易用和轻量级的管理工具。C/S架构，由Master和Minion构成，通过ZeroMQ进行通信。Saltstack的master端监听4505与4506端口，4505为salt的消息发布系统，4506为salt客户端与服务端通信的端口；salt客户端程序不监听端口，客户端启动后，会主动连接master端注册，然后一直保持该TCP连接
