Dnsmasq не выдаёт адрес

[Обедающий философ]

Здравствуйте!

Сделал точку доступа приблизительно так: http://help.ubuntu.ru/wiki/wifi_ap . На точке доступа и на ноутбуке squeeze 64. По беспроводу всё хорошо, а по проводу не выдаётся айпи-адрес. В то же время винда (на том же ноутбуке) замечательно коннектится. Кто виноват и что делать?

Заранее благодарен.

В то же время винда замечательно коннектится

Значит все-таки выдает? Тогда вопрос в том, что ноут с линуксом не хочет их брать. Там точно стоит в настроках получать адрес от dhcp? Что используете: ipfw или NetworkManager?

Подключаюсь через ifup.

Подключаюсь тем же ноутбуком к другой сети. Когда только загружается, то айпи получает. В то время как ежели вынуть провод и снова воткнуть, то получает шиш. Причём не помогает ни ifdown/ifup, ни sudo service networking restart, а помогает только перезагрузка. Порой (но далеко не всегда) выдаёт следующее:

когда в ноут провод втыкаешь, что пишется в dmesg?
в консоли запускаешь:

Код Выделить Развернуть

root@nfs-client: # tailf /var/log/dmesg

и вставляешь провод.

Dmesg молчит с обеих сторон. Syslog со стороны сервера:

Затем я его подключил к ещё одной сети (dd-wrt), она даже законнектилась (после ifdown и ifup) и даже получилось установить ssh-соединение, однако счастье было недолгим - через время порядка минуты соединение безвозвратно исчезло. Логи сервера показать не могу, ибо в dd-wrt они не ведутся.
