Boa noite pessoal, hj gostaria de pedir um grande favor eu estou dando assistencia a um telecentro na qual eles usam um sistema chamado tucunaré baseado em debian , esses dias o pessoal pediram para mudar o dns , so que quando mudei , a rede dos thinclient parou e pegar entao resolvi, por o dns dentro do dhcpd.conf,alterei o dns na linha "option domain-name-servers" entao toda vez que eu tento reiniciar o serviço da erro , então logo abaixo esta minha configuraçao do dhcpd.conf

"authoritative;
log-facility local7;
get-lease-hostnames true;
use-host-decl-names on;
next-server 192.168.17.254;
option root-path " 192.168.17.254:/opt/ltsp-4.2/i386";
option routers 192.168.17.254;
option domain-name-servers 200.198.6.171;
option subnet-mask 255.255.255.0;
option broadcast-address 192.168.17.255;

subnet 192.168.17.0 netmask 255.255.255.0 {
range 192.168.17.21 192.168.17.250;
if substring (option vendor-class-identifier, 0, 9) = "PXEClient" {
filename "/lts/2.6.20.9-ltsp-1/pxelinux.0";
} else {
filename "/lts/vmlinuz-2.6.20.9-ltsp-1";
}
host comp001 {
hardware ethernet 00:00:00:00:00:00;
fixed-address 192.168.17.1;

if substring (option vendor-class-identifier, 0, 9) = "PXEClient" {
filename "/lts/2.6.20.9-ltsp-1/pxelinux.0";
} else {
filename "/lts/vmlinuz-2.6.20.9-ltsp-1";
}
}

host comp002 {
hardware ethernet 00:00:00:00:00:00;
fixed-address 192.168.17.2;

if substring (option vendor-class-identifier, 0, 9) = "PXEClient" {
filename "/lts/2.6.20.9-ltsp-1/pxelinux.0";
}

"

# Vc tem os seguintes endereços:
Eth0: 192.168.0.1
Eth1: 192.168.52.1

Mas no arquivo dhcpd.conf vc configurou com range x.x.17.x

blá blá
blá blá
option broadcast-address 192.168.17.255;

subnet 192.168.17.0 netmask 255.255.255.0 {
range 192.168.17.21 192.168.17.250;
blá blá
blá blá


# Sua Rede eth0 = usa range "0"
# Sua Rede eth1 = usa range "52"
assim vc deixa seu "dhcp" doido.

- - -
Vc precisa configurar o arquivo de acordo com suas redes.

depois eu usei o comando dhcp3 -d e apareceu isso:
