Bootstrapping to custom ports and/or host names

While implementing the bootstrap to custom ports and host names functionality I wrote this small "guide" on how to use the features and see if it worked.

Important: I have the repositories ~/cfengine/masterfiles and ~/cfengine/core on my machine. If you want to install from source you will need to adjust these paths accordingly to your folder locations.

PREREQUISITES

Add hostname (Optional)

If you want to test with a custom hostname, you can add it to /etc/hosts:

import random

attempts = 20000
choices = 25

def one_test(possibilities):
    found = []
    num = 0
    while len(found) < possibilities:
        r = random.randint(1,possibilities)

Windows development machine on AWS

This outlines the steps needed to set up windows machines in AWS, and install the bare minimum requirements for development machines (notepad++, OpenSSH, gdb). I used windows server 2008R2 SP1 64-bit, procedure for other version should be very similar.

Important: If you just want to use a machine already set up, like the windows 2008R2 dev machine, scroll down to "Spawning a new machine".

Installation / First time setup

Select country

Instances/Images are stored per country, so make sure you have selected the appropriate country. If unsure, use Ireland.
