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.

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.

configuring IPTABLES on my RH7.1 Router and want to acomplish the following...
- Keep WAN card "Locked Down" to only accept SSH connections (-A INPUT -i eth1 -p tcp --dport 22 -j ACCEPT) and DHCP renews from my providor (-A INPUT -p tcp --sport 67 --dport 68 -i eth1 -j ACCEPT).
- Keep LAN card wide open so I can run WU-FTPD/DHCPD/SSH on the LAN (-A INPUT -i eth0 -j ACCEPT)
Found that when I change the INPUT IPTABLES policy to DROP(-P INPUT DROP) I can no longer FTP in from the LAN. Change the Policy to ACCEPT and it works great, but I want the default policy to DROP...
Anyone doing this with success? I am concerned that I may need the KERNEL patch with the IPTABLES update, but not sure - hoping to hear that others out there are doing this combo with success.
Everything is working great besides this, just a little troubling to change the default policy to ACCEPT just to FTP in... Most likely this is due to my lack of knowledge on WU-FTPD - Could it be that the WU-FTPD daemon binds to a certain card/IP?
