GeoffWilliams / myfact.rb

Last active June 10, 2016 05:29

Example of how to do a custom fact parsing output from a perl script that outputs YAML. This ruby file must be distributed via a module as a custom fact and should be saved in the modules lib/facter directory. The facter command can then be used to inspect the resulting structure, eg facter -p myfact.testdata.data1

	require 'yaml'

	Facter.add(:myfact) do
	setcode do
	YAML.load(Facter::Core::Execution.exec("/usr/local/bin/mycoolscript.pl"))
	end
	end

Generate cool names for things that are hard to name from a wordlist. Entries in the wordlist should start with star and a space, one per line. Other notes will be ignored

	parser = argparse.ArgumentParser(description="Generate names from wordlist")
	parser.add_argument('--wordlist', default='wordlist', help='wordlist file to read')
	parser.add_argument('--iterations', default=100, type=int, help='how many words to generate?')
	parser.add_argument('--words', default=3, type=int, help='how many words to fuse together')
	parser.add_argument('--min', default=2, type=int, help='min letters to pick from word')
	parser.add_argument('--max', default=4, type=int, help='max letters to pick from word')

Convert copy and pasted plaintext zendesk support ticket data into a html table - you can then open it in excel and manipulate the data :) how to use: copy the body of the helpdesk ticket and paste into a plain text file called ticket.txt, then run this script and capture the output. Save as .xls to open in excel

	#!/usr/bin/env python

Created November 18, 2016 03:51

Quick way to test out puppet SSL connections that are giving crazy ssl errors, adapted from http://www.masterzen.fr/2010/11/14/puppet-ssl-explained/ to not need you to type any paths. Ctrl+f to send a request. Thanks to Ben Ford from Puppet.com for putting me on to this!

openssl s_client -host $(puppet config print server) -port 8140 -cert $(puppet config print certdir)/$(puppet config print certname).pem -key $(puppet config print privatekeydir)/$(puppet config print certname).pem -CAfile $(puppet config print certdir)/ca.pem
