Всем привет!
Интересная вещь у меня на компе творится.
Стоит Junior 2.0 некотрыми пакетами обновленными из сизифа (в т.ч.
glibc). Машина подключена к интернет по DLS (Точка.ру). Поверх DSL
работает pppoe (PPP over Ethernet), т.е. соединение и аунтификация
происходит по PPP.
Жил не тужил, горя не знал. И тут у прова днсы забарахлили ( в принципе
бывает у них иногда такое, хотя редко очень и не на долго), т.е. то
резолвятся хосты, то нет. Ну думаю пора ДНС поставить, тем более что
давно собирался это сделать, да руки не доходили, а тут такой повод.
Поставил. Взял тот что из дистрибутива джуниора. Все поначалу работало
(первые минут 5) а потом перестало. Т.е. хосты что в кэше резолвятся, а
остальные нет. Потом опять заработало, потом опять перестало и т.д. При
этом если использовать внешний ДНС то все ок. Т.е. пишу "host
www.yauza.ru 127.0.0.1" получаю "Host not found, try again.", пишу host
www.yauza.ru 195.34.32.10 (ДНС прова) все ок. При этом провайдер божится
что никакой фильтрации трафика у него нет и он в этом никак виноват быть
не может. Для пробы взял 100% работающий на др. машине ДНС, собранный
статически (т.е. никаких .so-шек не требующий) -- абсолютно таже
история, то работает, то нет. Причем, на мой взгляд бессистемно.
root.hints взял с рабочего серва.
В тот момент когда ничего не работает ДНС орет в лог lame server
resolving на попытку резолва любого хоста. Версия ДНС в дистре -- 8.3.1,
версия бинда собранная ручками со --static -- 9.2.1.
Сижу под динамическим ИП'ом, имеющим отображение в доменное имя. Т.е.
весь диапазон динамических айпи имеет как прямое так и обратное отображение.
Хотелось бы попробовать притащить домой машину с нормально работающим
ДНС и посмотреть как она себя поведет, но, к сожалению, не имею сейчас
такой технической возможности :(*
Может у кого есть идеи по поводу дальнейшей диагностики проблемы?
Далее шлю кусок лога tcpdump'а в момент попытки резолва:
[hmepas на localhost hmepas]$ host irc.yauza.ru
Host not found, try again.
при этом
[hmepas на localhost hmepas]$ host irc.yauza.ru 195.34.32.10
Using domain server 195.34.32.10:
irc.yauza.ru is a nickname for ns.yauza.ru
ns.yauza.ru has address 217.150.60.1
[hmepas на localhost hmepas]$ sudo tcpdump -i ppp0 &> log
User level filter, protocol ALL, datagram packet socket
tcpdump: listening on ppp0
