Fabric

Fabric is a Python (2.5 or higher) library and command-line tool for streamlining the use of SSH for application deployment or systems administration tasks.

It provides a basic suite of operations for executing local or remote shell commands (normally or via sudo) and uploading/downloading files, as well as auxiliary functionality such as prompting the running user for input, or aborting execution.

More from Fabric documentation -- > http://docs.fabfile.org/en/1.6/


$ sudo apt-get install fabric

Create new python file

$ nano fabfile.py

insert code

def hi():
print("Hello World!")

$ cat fabfile.py

$ fab -l (list functions)

Install ssh + server
$ apt-get install openssh-server

import fabric library to fabfile.py

from fabric.api import*

env.hosts=["localhost", "172.28.9.100"]

passwd on live cd

Run function from python script

$ fab koneenimi

Make ssh login automatic with keys

$ ssh-keygen
$ ssh-copy-id xubuntu@localhost

sudo visudo

add line under #allow members of group sudo to execute any command

xubuntu ALL=(ALL) NOPASSWD: ALL

to see if package installed correctly
$ dpkg -s softwarename

And now I just post wall of code here. Remember that this is Python so indents must be correct to get this to work!
