erro placa de rede

uma coisa intrigante, sempre usei eth0 , mais para rodar meu servidor preciso de um dhcp na maquina e agora estou com erro ao rodar o serviço
oot@sunray:/home/sunray# /etc/init.d/networking restart
[....] Restarting networking (via systemctl): networking.serviceJob for networking.service failed because the control process exited with error code.
See "systemctl status networking.service" and "journalctl -xe" for details.
failed!
alguem poderia me ajudar por onde começo ?
