Using OS X as a Syslog Server

This document describes how to set up an OS X to be a syslog server that logs messages from the local network. It was largely meant for my own purposes so that I don't forget what I did, but feel free to use it for your own purposes.

A problem with just "turning this on" is that you will not see the correct hostname in the syslog entries. What we will do is use

Using Rspec with Rails 4 patch method

In Rails 4 PATCH is the new HTTP methode for an update action. You can find the details here: http://weblog.rubyonrails.org/2012/2/25/edge-rails-patch-is-the-new-primary-http-method-for-updates/

Using PATCH in your specs

As you can imagine you need to use the PATCH method to test the update action in your controller. Because of how the users controller in this example works you need to specify the id and user. This particular spec tests whether the user gets redirected if it's not logged in.
