Hi Syndi's...

Something I found which I found quite interesting/humorous.

Upside-Down-Ternet

My neighbours are stealing my wireless internet access. I could encrypt 
it or alternately I could have fun.
Split the network

I'm starting here by splitting the network into two parts, the trusted 
half and the untrusted half. The trusted half has one netblock, the 
untrusted a different netblock. We use the DHCP server to identify mac 
addresses to give out the relevant addresses.
/etc/dhcpd.conf

ddns-updates off;
ddns-update-style interim;
authoritative;

shared-network local {

        subnet *.*.*.* netmask 255.255.255.0 {
                range *.*.*.* *.*.*.*;
                option routers *.*.*.*;
                option subnet-mask 255.255.255.0;
                option domain-name "XXXXX";
                option domain-name-servers *.*.*.*;
                deny unknown-clients;

                host trusted1 {
                        hardware ethernet *:*:*:*:*:*;
                        fixed-address *.*.*.*;
                }
        }

        subnet 192.168.0.0 netmask 255.255.255.0 {
                range 192.168.0.2 192.168.0.10;
                option routers 192.168.0.1;
                option subnet-mask 255.255.255.0;
                option domain-name-servers 192.168.0.1;
                allow unknown-clients;

        }
}


IPtables is Fun!

Suddenly everything is kittens! It's kitten net.
