Установке сервера DHCP - не удается запустить/остановить его

Я следую этому руководству. Я абсолютно плохо знаком с Ubuntu, работающей над 14.04 LTS.

Когда я достигаю последнего шага прежде, чем иметь дело с Kerrighed (половина пути через учебное руководство), я пытаюсь запустить свой сервер DHCP, но это перестало работать.

root@MASTER:~# /etc/init.d/tftpd-hpa restart
root@MASTER:~# /etc/init.d/isc-dhcp-server restart

Вот то, что я вошел в системный журнал путем ввода dmesg:

Вот/etc/dhcp/dhcp.config:

# General options
option dhcp-max-message-size 2048;
use-host-decl-names on;
deny unknown-clients; # This will stop any non-node machines from appearing on the cluster network.
deny bootp;

# DNS settings
option domain-name "kerrighed";          # Just an example name - call it whatever you want.
option domain-name-servers 192.168.1.1;  # The server's IP address, manually configured earlier.

# Information about the network setup
subnet 192.168.1.0 netmask 255.255.255.0 {
  option routers 192.168.1.1;              # Server IP as above.
  option broadcast-address 192.168.1.255;  # Broadcast address for your network.
}

# Declaring IP addresses for nodes and PXE info
group {
  filename "pxelinux.0";                 # PXE bootloader. Path is relative to /var/lib/tftpboot
  option root-path "192.168.1.1:/nfsroot/kerrighed";  # Location of the bootable filesystem on NFS server

  host M4500_1 {
        fixed-address 192.168.1.101;          # IP address for the first node, kerrighednode1 for example.
        hardware ethernet XX:XX:XX:XX:XX:XX;  # MAC address of the node's ethernet adapter
  }


  server-name "kerrighedserver"; # Name of the server. Call it whatever you like.
  next-server 192.168.1.1;       # Server IP, as above.
}

(Адрес MAC является корректным в файле),

Вот и т.д./объединять в сеть/соединять интерфейсом:

# The loopback interface:
auto lo
iface lo inet loopback

#auto eth0
# The primary network interface, manually configured to protect NFS:
iface eth0 inet static
address 192.168.1.1
netmask 255.255.255.0

Подключенный ведомый компьютер (для кластеризации) говорит PXE-E51 : No DHCP or proxyDHCP offers were received. Поэтому похоже, что сервер DHCP является definitiely, не работающим. Tftpd не дает ответа, когда я перезапускаю его в терминале, и nfs выглядит хорошей все же.
