Как я могу исправить " нет объявления подсети для перезапуска (0.0.0.0)"?

у меня есть служба DHCP, установленная на моем дистрибутиве, Backtrack 5 R2 (ubuntu 10.04), и она работала нормально, но когда я начал настраивать DNS, она внезапно остановилась, как я могу заставить ее работать снова??

dhcp.файл conf:

ddns-update-style none;
option domain-name "admin.servers.net";

default-lease-time 600;
max-lease-time 7200;
authoritative;
log-facility local7;

subnet 192.168.0.0 netmask 255.255.255.0 {
  range 192.168.0.50 192.168.0.100;
  option domain-name-servers 192.168.0.2, 8.8.4.4;
  option routers 192.168.0.254;
  option broadcast-address 192.168.0.255;
  default-lease-time 600;
  max-lease-time 7200;
}

и когда я перезапускаю сервис, он показывает:
