Отвалилась сеть. Причина неизвестна.

[Protopopulus]

Доброго вечера. Имеется:
   1. ПК с Ubuntu 10.04 на борту.
   2. Подключение по VPN к проводному интернету beeline.
   3. Две сетевые карты - одна интегрированная, вторая PCI (заведомо исправная).

Проблема:
   Нет подключения к сети по eth0, и, как следствие, по ppp0.

Что делал:
   Перезапускал сеть посредством /etc/init.d/networking, проверял маршрутизацию, ставил заведомо исправную сетевую карту и настраивал второй eth-интерфейс. В любом случае сетки нет.

Логи прилагаю:

Так и не могу понять в чем причина неисправности... Произошло это все после поломки в сети. Приходили техники с пчелайна и говорили, что у них порт на оборудовании погорел. Также, подключались нетбуком к проводу - интернет был, то есть, сеть исправна.

Доступа к компу сейчас нет - он в паре кварталов от меня.

Подскажите как быть.

[terminalko]

имею опыт работы в провайдерской сети. знаком с горением портов ... печальная вещь, в половине случаев горит порт на железке провайдера (смена порта пришедшим ремонтником и затыкание погоревшего бумажкой) остальная половина сопровождается горением сетевки на другом конце кабеля. в основном часто замечано во время гроз , но так же при скачках или коротких замыканиях, если рядом с тем что замкнуло лежит витуха (а как правило на чердаке кроме силовых кабелей крепить особо не к чему ) есть позможность проверить сетевку ?

[Protopopulus]

Втыкал заведомо исправную, для этого и купленную в магазине, сетевуху в PCI - результат тот же.

билайн выдает по DHCP айпишники ? или нет

если не ошибаюсь eth1 хочет получить айпишник который присвоен eth0
попробуй отключить в биосе встроеную сетевку \ или назначить ей левый айпишник + передернуть сеть \ либо позвонить в билайн саппонт , попросить девушку выдать на мак 00:e0:52:ae:f0:6a другой айпи адрес (по умолчанию сетки из 8 айпишников на абонента идут)

гарантии нет, но вдруг
