I use puppet to manage the configuration of the machines I manage. So far, I've been rolling out new resources to machines but recently I've wanted to remove resources from machines. Here's how I modified my cron classes so I could remove cron jobs as well as create them.

In my iptables configurations, I generally allow all traffic I am interested in and deny the rest, logging anything that is denied. I found that this can get a bit noisy with loads of connections to udp:137 and udp:500, etc. so I decided to deny the more common ports without logging. But which are the most common ports?

I've used subversion for quite a while now – I vaguely remember using CVS when working with some Sourceforge projects, but most of my experience is with subversion. I've used the command svn status (or svn st , for short) to show me what changes there are in my working copy. However, I've occasionally thought it would be nice to see what updates are available in the repository but I've never bothered to find out how to do it. Until now…
