qwik-linux-firewall-liveCD Version 1.5

Description

This is a liveCD respin of FC6 customized to use as a firewall. Contains networking utilities. 
Automatically logs in as root.

Instructions For Use

The livecd will automatically load it's configuration and run without user intervention. All that is needed is a 
fat32 floppy that contains the configuration files in its root directory:

firewall.fw - this is generally a bash script that contains the firewall rules. This is also responsible for 
generating network interfaces and route tables which the firewall logic depends on. Usually all this can be created 
using Firewall Builder, however hardcore iptables experts can put their own rulelist here.

hosts - as in, the copy of /etc/hosts that the firewall should use in place of the default one. This is optional.

hosts.allow, hosts.deny- also belongs in /etc, which are rules for tcp-wrappers. This is optional.

resolv.conf - to be copied to /etc/resolv.conf, which provides a listing of DNS servers used for lookups.

misc.sh - a shell script which will run after all above has been configured. This is a great place to change the root
password with a hash, add users, modify the routing table, etc. The possibilities here are limitless. If you have 
special requirements for the firewall, the changes to make it so would be put here.

Notable components

iptables- kernel level stateful firewall
ssh- remote login
telnet/nc- for basic network testing/service discovery
openssh-server- for login and administration from remote hosts
bind-utils- for querying DNS
iptraf- text-mode traffic monitor
tcpdump- used for recording network traffic for later inspection by applications like Wireshark

This liveCD is under the General Public Licence. As with all software under the GPL, USE AT OWN RISK.
With that said, Have Fun!
