Snort 2.7.0.1

Snort project is a "lightweight" intrusion detection technology in comparison to commercially available systems.
Snort really isnt very hard to use, but there are a lot of command line options to play with, and its not always obvious which ones go together well. This file aims to make using Snort easier for new users.
Snort can be configured to run in four modes:
- Sniffer mode, which simply reads the packets off of the network and displays them for you in a continuous stream on the console (screen).
- Packet Logger mode, which logs the packets to disk.
- Network Intrusion Detection System (NIDS) mode, the most complex and configurable configuration, which allows Snort to analyze network traffic for matches against a user-defined rule set and performs several actions based upon what it sees.
- Inline Mode, which obtains packets from iptables instead of from libpcap and then causes iptables to drop or pass packets based on Snort rules that use inline-specific rule types.
