Introduction

This chapter promotes some interesting Python libraries. The recipes are presented aiming at the system administrators and advanced Python programmers who like to write code that connects to remote systems and executes commands. The chapter begins with lightweight recipes with a built-in Python library, telnetlib. It then brings Paramiko, a well-known remote access library. Finally, the powerful remote system administration library, fabric, is presented. The fabric library is loved by developers who regularly script for automatic deployments, for example, deploying web applications or building custom application binaries.
