Introduction
------------
Reading network traffic is essential for system administrators, network engineers, and security analysts.
At some point there will be a need to read the network traffic directly instead of monitoring application
level details. Examples of situations that might require monitoring network traffic are, auditing network
security, debugging network configurations, and analyzing usage patterns. For this task we use network
monitoring software, or network sniffers, that sniff the traffic your computer is able to see on the
network. What exactly your computer can see really depends on how the network is laid out, but the
easiest way to figure out what it can see is just start sniffing.
The most common tools to do the job are readily available. Many are even free to download and use.
