DHCP server setup on RH Linux - Not configured to listen on any interfaces!

Hi all,

I am trying to setup DHCP server on a Linux machine. After configuring
/etc/dhcpd.conf file and restarting the dhcpd service, here is what I
see:

Shutting down dhcpd: [FAILED]
Starting dhcpd: Internet Systems Consortium DHCP Server V3.0.1rc14
Copyright 2004 Internet Systems Consortium.
All rights reserved.
For info, please visit http://www.isc.org/sw/dhcp/
Wrote 0 leases to leases file.
No subnet declaration for eth0 (0.0.0.0).
** Ignoring requests on eth0. If this is not what
you want, please write a subnet declaration
in your dhcpd.conf file for the network segment
to which interface eth0 is attached.
Not configured to listen on any interfaces!


As a matter of fact etc/sysconfig/dhcpd file contains the following
line:
DHCPDARGS=eth0

I wonder why it still gives "Not configured to listen on any
interfaces!" error.


Here is how the /etc/dhcpd.conf file is setup:

ddns-update-style interim;
ignore client-updates;
subnet 10.10.10.0 netmask 255.255.255.0
{
# --- default gateway
option routers 10.10.10.1;
option subnet-mask 255.255.255.0;
# option nis-domain "domain.org";
# option domain-name "domain.org";
# option domain-name-servers 192.168.1.1;
# option time-offset -18000; # Eastern Standard Time
# option ntp-servers 192.168.1.1;
# option netbios-name-servers 192.168.1.1;
# --- Selects point-to-point node (default is hybrid).
# --- Don't change this unless
# --- you understand Netbios very well
# option netbios-node-type 2;
range dynamic-bootp 10.10.10.15 10.10.10.200;
default-lease-time 21600;
max-lease-time 43200;
# we want the nameserver to appear at a fixed address
# host ns {
# next-server marvin.redhat.com;
# hardware ethernet 12:34:56:78:AB:CD;
# fixed-address 207.175.42.254;
# }
}


Here is the result of "ifconfig -a" on my Linux box -

eth0 Link encap:Ethernet HWaddr 00:15:C5:4E:C3:36

Please help!

I don't see the IP address of the eth0 interface on the ifconfig
output. May be assigning it a static ip address (preferably on the same
subnet on which you plan to dole out ip addresses) could help.
