RadSSH

RadSSH is a Python package that is built with Paramiko.

Documentation for the project is hosted on ReadTheDocs, at http://radssh.readthedocs.org

Frequently Asked Questions: https://github.com/radssh/radssh/blob/master/FAQ.md

RadSSH is installable via pip, using pip install radssh.

The RadSSH shell behaves similar to a normal ssh command line client, but instead of connecting to one host (at a time), you can connect to dozens or even hundreds at a time, and issue interactive command lines to all hosts at once. It requires very little learning curve to get started, and leverages on existing command line syntax that you already know.

RadSSH includes a loadable plugin facility to extend the functionality of the shell with basic Python scripting, as well as a high level API that can be used to build stand alone applications for dedicated SSH control processing in a parallel environment.
