An Open Source Layer 2 Switch

Most networks are made up of expensive proprietary hardware and software incorporating a set of unique commands. Cost constraints and lack of knowledge often impede the implementation of such networks in a small business environment. Linux, ebtables, NTOP, samhain and iptables can provide similar functionality at a faction of the cost and within a familiar environment. Our goal is to give a step-by-step explanation of how to implement this solution for a mid-size company. What results is a window onto network performance giving us the ability to identify bottlenecks, and help troubleshoot problems. The network will be more resilient to failure and malicious activity.
