[K12OSN] dhcpd on fresh LTSP3.1.1 running, but no offers



hi all, i am being driven to distraction by some *very simple* dhcpd
problem...  it's a basic home/demo LTSP, has worked well through several
versions. it's last was LTSP 3.1 upgraded to 3.1.1 via apt-get. replaced
NIC with Intel 10/100/1000, kudzu found/configured it fine... but the
clients didn't get DHCP offer. unbound/reprobed the ETHx mac addresses
from the GUI, no joy.

<long configuration juggling story deleted here. one small HD 99% full,
copied /home dirs off, replaced HD>

decided to fresh install 3.1 from CD's, then immediately upgraded via
apt-get. now, none of my clients (X86 PC's and Intel 810 PXE that all used
to work) are getting the DHCP offer.  the hardware/rest of network seems
fine, i can plug Winderrs PC with 192.168.0.x IP into the clients' switch,
point it's gateway to the LTSP box, and it's online fine.  from DMESG: 

e1000: eth0 NIC Link is Up 1000 Mbps Full Duplex

dhcpd is running, can stop/restart it w/no complaints. /etc/dhcp.conf all
looks like normal default stuff (like it was before):

option domain-name            "ltsp";
option root-path              "192.168.0.254:/opt/ltsp/i386";

looking through /var/log/messages, instead of these old msgs:
dhcpd: DHCPDISCOVER from 00:d0:b7:ac:d3:6e via eth0
dhcpd: DHCPOFFER on 192.168.0.253 to 00:d0:b7:ac:d3:6e via eth0

i'm now seeing this:

dhcpd: No subnet declaration for eth1 (10.10.10.9).
dhcpd: ** Ignoring requests on eth1.  If this is not
what
dhcpd:    you want, please write a subnet declaration
dhcpd:    in your dhcpd.conf file for the network segment
dhcpd:    to which interface eth1 is attached. **
dhcpd: No subnet declaration for eth1 (10.10.10.9).
dhcpd:
dhcpd: ** Ignoring requests on eth1.  If this is not what
dhcpd:    you want, please write a subnet declaration
dhcpd:    in your dhcpd.conf file for the network segment

dhcpd: Listening on LPF/eth0/00:07:e9:0a:29:7b/WORKSTATIONS
dhcpd: Sending on LPF/eth0/00:07:e9:0a:29:7b/WORKSTATIONS
dhcpd: Sending on  Socket/fallback/fallback-net

which, i didn't want DHCP on eth1 anyway. i feel this has to be something
terribly simple, i'm just looking all around it.

thanks,
ss
