На прокси пропадает интернет в будние дни.

Здравствуйте. Понимаю что тем таких много в интернете. К сожалению у меня не хватает знаний чтобы понять причину и расшифровать логи—почему падает сетевая карта. Потому прошу помощи у знающих.

Есть компьютер раздающий интернет с двумя сетевыми картами:eth0 и eth1. Eth0 с белым айпи смотрит в интернет, а eth1 раздаёт интернет в подсети.

Три дня интернет на eth0 пропадал примерно в 10 и в 16 часов. На четвёртый и пятый день интернет на eth0 пропал в 11:30. Работать интернет начинает когда перезагружу сетевые интерфейсы.

Ты ещё скажи, что у тебя GUI на proxy...

NetworkManager и avahi-daemon выкинь на мороз и настрой интерфейсы нормально для начала.

Проблема решилась

Виновником сбоя в интернете стал доктор веб.
