Keenetic Giga II: error while reading dhcp packet

Dimas_RTSL · April 11, 2017

Здравствуйте!

Имею Keenetic Giga II (2.08.C.1.0-0)

Подскажите, из-за чего может возникать ошибка "WEBADMIN_HOME: error while reading dhcp packet: resource temporarily unavailable."?

Забивает лог роутера с интервалом в 2 секунды

Предыстория - поменял провайдера в начале марта.

В момент настройки роутера увидел обновления прошивки.

Раз вышли обновления - обновился до V2.06(AAFS.1)C2 (какая стояла до этого не помню, до этого примерно осенью обновлялся)

Все работало нормально, но у нового провайдера что-то подглючивало вначале, интернет пропадал, поэтому я периодически поглядывал в лог роутера на предмет того, были ли сбои в течение дня, и какие.

недели две три все выглядело в общем-то нормально, пару раз в день обрывы, но жить можно

В очередной раз проверил лог - он был забит данными ошибками

Обращался в поддержку Keenetic, в поддержку провайдера. выполнял кучу рекомендаций, но не помогло.

Сегодня поставил 2.08, результат тот же

Направьте пжл, в каком направлении начать разбираться?

прикладываю часть лога в режиме отладки

Самое простое что могу предложить, скинуть на заводские настройки и всё настроить с нуля. Лог малоинформативен, ибо совсем непонятно, почему ваш пул адресов dhcp начинается аж с192.168.1.44, а компьютер зачем то поимел 192.168.1.33... Видимо что-то вы перекрутили с настройками.

Mamay · April 11, 2017

И очень странные udp checksum, да ещё в гостевой сети...

Dimas_RTSL · April 15, 2017

произвел сброс до заводских настроек. настроил роутер.

ошибки продолжаются.

В скрытом тексте кусок отладочного файла, в следующем скрытом сообщении - полный файл selftest

по сути, мне хочется понять суть ошибок.

Это DHCP роутера валится, или ошибки со стороны провайдера?

ошибки продолжаются.

В скрытом тексте кусок отладочного файла, в следующем скрытом сообщении - полный файл selftest

Можете снять дамп DHCP-пакетов с ISP-интерфейса? Встроенным "монитором". Было бы очень ценно.

Dimas_RTSL · April 16, 2017

сделал dump и приложил лог с расширенной диагностикой. self-test за этот же период в след. сообщении.

но выкладываю с отключенной фильтрацией пакетов, к сожалению, не смог разобраться до конца.

Читал https://wiki.wireshark.org/DHCP - попробовал фильтр "port bootps".

ни одного пакета не захватилось, после этого отключить захват и перенастроить параметры не получилось - кнопка остановки захвата не реагирует на нажатия

@Dmitry Ganaev Попробуйте отключить dhcp клиент на ISP подключении. Для этого зайдите в настройки подключения ISP и пункте "Настройка параметров IP" вместо автоматически поставьте "без IP-адреса".

Сделать это нужно для того, чтобы оценить возможное влияние dhcp клиента на работу dhcp сервера. Так как у вас pppoe, то dhcp клиент не требуется и он бестолку шлет discovery.

Dimas_RTSL · April 17, 2017

Отключил.

Не помогло.

в момент отключения сделал selftest, успел получить его, и связь с роутером через keenDNS пропала через какое-то время.

вложил файл

slomblobov · April 17, 2017

@Dmitry Ganaev Если не сложно, снимите пожалуйста небольшой дамп трафика с Home интерфейса. Главное, чтобы в него попали dhcp пакеты. Для этого можно использовать фильтр "udp and ( port 67 or port 68 )".

Так же после отключения dhcp клиента, которое вы уже выполнили, попробуйте перезагрузить роутер.

Dimas_RTSL · April 17, 2017

Роутер перегрузил, связь появилась. Включил монитор сетевых пакетов с данным фильтром.

пока абсолютно ничего не ловится.

ошибки при это продолжают падать с интервалом в минуту (64-65 сек )

настройки монитора привел. все корректно в них?

slomblobov · April 17, 2017

@Dmitry Ganaev На вид всё ок, разве что увеличить максимальный размер файла. Если dhpc пакетов нет, а ошибки сыпятся, то это весьма любопытный результат.

Dimas_RTSL · April 17, 2017

за 3 часа захвачено 18 dhcp-пакетов на интерфейсе "Home network"

ошибки раз в минуту так и генерятся, причем даже на Guest_AP, хотя в "сеть wi-fi>гостевая сеть" галка "Разрешить гостевой доступ" снята

нашел вот такую заметку: Linux, UDP checksum, на заметку

может быть как-то связано?
