如何使用python 2.3 rsh ssh

我想编写一个脚本来执行以下Linux命令序列：

rsh rr01（此处系统将询问密码）

ssh rr02（此处系统将再次请求密码）

在某个文件上激活我的应用程序

我天真地（愚蠢地）试图用一个简单的操作系统来实现这一点 请记住，我使用的是Python2.3，并且希望避免添加模块（如果可能的话）

提前谢谢

[EDIT]还可以查看另一个使用paramiko的示例

在上找到的脚本可能会对您有所帮助。它包括os模块（用于查找密钥）和用于日志记录的tempfile模块，这两个模块都可以在Python2.3全局模块索引（）和用于SSH2协议实现的paramiko（）中找到，这两个模块应该可以在Python2.3及更高版本上工作。这是一段简单的代码：

Python 2.3？！那太老了！（2003年7月29日）我知道。。。但是我不得不使用这个版本。。。你是说在较新的版本中，我们有简单而优雅的解决方案，而在2.3版本中，没有解决方案或复杂的解决方案？没有。但我不会碰任何强迫我使用九年前的软件的系统。
