Здравствуйте! В системе установлены три сетевые карты. Настроены dhcp, маршрутизация, smb, apache, mysql, redis, dns. Периодически падает случайный сетевой интерфейс. Причем причину падения я отследить не могу. Если падает интерфейс, через который сервер подключен к интернету я подключаюсь по ssh и помогает перезапуск /etc/unut.d/networking. Если падает интерфейс, идущий в локалку - только ребут, так как сервер - голый системник без клавиатуры и монитора... Мои конфиги:
