Install RackTables and start tracking your IP address inventory

Recently while I was scouring through a spreadsheet of “unallocated” IP addresses, I thought to myself. There has to be a better way to manage an inventory of IP addresses, and while I'm at it maybe even provide a list of provisioned servers. After some googling I found myself on RackTables.org the home of an open source project that aims to provide just what I was looking for. An Inventory system that tracks and manages Servers, Racks, IP Addresses and just about everything else in a data center.

Why you should avoid running applications as root

I'm going to start this post by saying what I'm really thinking. 90% of the time if an application is running as the root user on a Unix/Linux machine; it is because the sysadmin who setup or designed the environment was being lazy.
