instalar y configurar servidor dhcp

1 facil instalar dhcp
apt-get install dhcp

2 editar /etc/default/dhcp en caso de que eth0 no sea la interface a servir
INTERFACES="eth1"

3 editar /etc/dhcpd.conf
por en mi caso:
-----------------------------------------------
#option domain-name "puebla.megared.net.mx";
option domain-name-servers 10.44.0.4, 10.44.0.3 ;

default-lease-time 600;
max-lease-time 7200;

authoritative;

option subnet-mask 255.255.255.0;
# range 204.254.239.10 204.254.239.20;
option broadcast-address 192.168.255.255;
option routers 192.168.0.1;
#}

# The other subnet that shares this physical network
subnet 192.168.0.0 netmask 255.255.255.0 {
range 192.168.0.2 192.168.0.240;
}
------------------------------------------

nota:
ethx esta configurada con etherconf asi:

eth1 Link encap:Ethernet HWaddr 00:50:FC:3E:1C:E8
