A couple of weeks ago I setup iptables on my Slicehost VPS. After a few days of watching it  I was suprised at how many connections were being denied. This machine has only been public for a couple days or so and I only had one domain pointing to it too. Its been a few weeks now and the information I have gathered is pretty interesting, take a look.

Top 10 countries based on number of denied hosts:

Top 10 ports based on number of denied connections:

Here is a mash up I made using the Google Maps API. This representation only shows around 500 of the denied hosts but I think its a good view of where all the connections come from throughout the world. Now to only AJAX‘ify this thing and have a live view of where the denied hosts are coming from in the world.
