Настройка DHCP клиента на нетбуке

[ArcFi]

Насколько мне известно, насиловать /etc/dhcp/dhclient.conf вовсе не обязательно.
ID клиента можно указать в свойствах сетевого подключения в NetworkManager.

[AnrDaemon]

ArcFi, раз уже изнасиловали, надо как минимум исправить начатое.

[GlaIZier]

я же писал, что пробовал и так, и так, и с 1 и без 1, и в конфиге и в NM. Просто это последняя версия. Там я пытался без 1 мак прописать.

[AnrDaemon]

GlaIZier, вы не воду лейте, а дело показывайте.

Где такие провайдеры водятся? 

(Нажмите, чтобы показать/скрыть)

Если у Вас ещё не пропало желание разобраться почему всё-таки dhcp-сервер провайдера не хочет отвечать на запросы Вашего dhcp-клиента, сделайте дамп Wireshark'ом с попыткой получить адрес на Windows.
Т.е запускаете Wireshark, в cmd с повышенными правами
ipconfig /release
ipconfig /renew
Останавливаете сниффер, сохраняете дамп, выкладываете либо файлом, либо в текстовом виде с помощью tcpdump
tcpdump -S -nvvvv port 67 or port 68 -r /path/to/dump/file/wireshark.pcap
Оченно интересно, что такого шлёт dhcp-клиент Windows ,что dhcp-сервер отввечает на его запросы и не отвечает на запросы dhclient...

[GlaIZier]

KT315,
Извините за задержку.

Сделал так.
Загрузился в винде.
Отключил беспроводное соединение
Запустил сниффер
Подключился через трей к вайфай
В командной строке набрал ipconfig /release ipconfig /renew
Остановил сниффер и сохранил дамп.

Далее перезагрузился из-под Ubuntu
sudo tcpdump -S -nvvvv port 67 or port 68 -r ~/home.pcap

Попробуйте сказать dhclient'у, чтобы он ещё отсылал option 60, сходный с windows
/etc/dhcp/dhclient.conf
send host-name "<hostname>";
send dhcp-client-identifier 1:74:2f:68:2d:68:f1;
send vendor-class-identifier "MSFT 5.0";

Может вам целиком файлом дамп с wireshark скинуть? Тот, что из-под винды.

[koshev]

Скиньте тогда оба дампа. Но, признаться честно, у меня идеи кончились.

Стали происходить странные вещи. В некоторых местах подключение по DHCP стало работать . Буду дальше наблюдать.

[ArcFi]

Оно?

[GlaIZier]

ArcFi,
Похоже на то. В двух местах, где я не могу подключиться стоит шифрование WPA2-PSK. В местах, где могу стоит шифрование WPA-PSK и незащищенная сеть(web-авторизация).

Только я не понял, там что-то какие-то разные рецепты решения проблемы. То ли говорят что-то удалить, что-то поставить, то ли обновление какое-то скачать . С чего начать?
