Почему после запуска мне нужно запускать /etc/init.d/networking restart для работы сети? [закрыто]

Я только что исправил установку grub и обнаружил, что мое проводное сетевое соединение не работает. В конце концов, у меня все заработало, но каждый раз, когда я перезагружаюсь, мне приходится вручную перезапускать сетевую службу, чтобы подключиться к сети. Как заставить сеть работать автоматически?

Вот соответствующая информация.

Запуск ifup дал:

$sudo ifup eth0
Unknown interface eth0=eth0

dhclient , тоже не сработало. В конце концов я взглянул на / etc / network / interfaces , и eth0 отсутствовал:

auto lo
iface lo inet loopback

который я изменил на:

auto eth0
iface eth0 inet dhcp
#auto lo
#iface lo inet loopback

Ошибка, вызванная ifup ушел, но dhclient по-прежнему не дал мне IP, но перезапуск сетевого интерфейса дал:

$ sudo /etc/init.d/networking restart
