Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

Insert this chain:

iptables -N block
iptables -A block -m state --state ESTABLISHED,RELATED -j ACCEPT
iptables -A block -m state --state NEW -i ! eth0 -j ACCEPT
iptables -A block -j LOG --log-prefix "DROP UNTRUSTED NETWORKS "
iptables -A block -j DROP
Then I edited /etc/syslog.conf
# Log all kernel messages to the console.
# Logging much else clutters up the screen.
You can also add the log file on logrotate.d so it will not accumulate. Dont forget to restart syslog
