Okay, this is a followup to my earlier question on DHCP.

I got the DHCP client working. But, lets begin with the problems.

Problem 1: DHCP attempts to query eth0, eth1, and lo for an address.
I want it to only list on eth0, my so-called WAN port (ie the one
connected to @home). I want this to work better.

Problem 2: I want to run a DHCP server on eth1. This will handle all the
masqueraded machines.  I have modified the init script to start dhcp
like this: "dhcp eth1" to have it start on eth1.

Now, I try to start the dhcp server and get this:

    No subnet declaration for eth1 (
    Please write a subnet declaration in your dhcpd.conf file for the
    network segment to which interface eth1 is attached.

Here is what is in my dhcpd.conf:

# option definitions common to all supported networks...
option domain-name "blvue1.ne.home.com";
option domain-name-servers,;

option subnet-mask;
default-lease-time 600;
max-lease-time 7200;

subnet netmask {

Okay, now, what do I need to fix to get this working right? Im running
out of time to get my @home-mandated reconfiguration done.

#define m(i)(x[i]^s[i+84])<<
unsigned char x[5],y,s[2048];main(n){for(read(0,x,5);read(0,s,n=2048);write(1,s
,n))if(s[y=s[13]%8+20]/16%4==1){int i=m(1)17^256+m(0)8,k=m(2)0,j=m(4)17^m(3)9^k
