Всем с наступающим!
Сразу извиняюсь за нубский вопрос, как обычно с меня пиво.
Есть пк (Debian), работал как домашняя шара, один плохой человек попытался настроить на нем раздачу интернета. Действия его не известны. Что получилось. Сеть не расширена и eth0 сеть не видит, интернета нет, ip не получает. После dhclient eth0 - все становиться нормально, но после перезагрузки все то же самое. Не могу понять каких настроек не хватает.

Хотелось бы вернуть все как было, а то каждый раз вводить dhclient после перезагрузки не удобно.
Заранее спасибо за помощь!
