Я думаю, эта ситуация знакома многим. Некоторые в нее попадали сами, у кого-то с ней сталкивались знакомые, а кто-то встречал таких админов на форумах и прочих конференциях. Данная статья посвящается тому, отчего это бывает, и как решить эту проблему. Термины, необходимые для понимания статьи MTU Maximum Transmission Unit — этот термин используется для определения максимального размера пакета в байтахкоторый может быть передан на канальном уровне сетевой модели OSI.
Для Ethernet это байт. Если приходит пакет большего размера например по Token Ringто данные пересобираются в пакеты размером не более MTU т е не более байт. Операция пересборки пакетов под другой MTU называется фрагментацией fragmentation и является затратной для маршрутизатора. Описана в RFC в году. Это приводит к тому, что узел, значение MTU которого меньше размера пакета, отклоняет передачу пакета и отправляет сообщение ICMP типа Destination is unreachable Хост недоступен.
К сообщению об ошибке прилагается значение MTU узла. Хост-отправитель уменьшает размер пакета и отсылает его заново. Такая операция происходит до тех пор, пока пакет не будет достаточно мал, чтобы дойти до хоста-получателя без фрагментации. Рассчитывается по следующей формуле: Итого обычно это байт.
Когда соединение устанавливается, каждая сторона может объявить свой MSS. Выбирается наименьшее значение. Подробнее можно посмотреть. Тестовый полигон С данной проблемой лучше всего знакомится на практике но не в цейтноте, когда начальство орет над ухом.
Для этого я создал тестовую сеть, изображенную на рис. Тестовая сеть. Это упрощенный вариант глобальной сети. Компьютер с именем deb-serv представляет собой наш маршрутизатор на Linux.
Внимание — на его интерфейсе eth2 размер MTU уменьшен до байт; 2. Получаем с www. Конечно, в реальности цепочка гораздо больше, но для показательного примера этого хватит. В разных точках сети я контролирую ситуацию с помощью программы tcpdump. Изучаем, как пойдут пакеты с веб-сервера.
Flags [S], seqwinoptions [mss Flags [S. Flags [. Flags [P. ICMP В строках с 1-ой по 3-ю мы видим установку tcp соединения. Здесь стоит обратить внимание на поле опций, а именно на параметр MSS, которым обмениваются стороны. С обеих сторон это байт. В строке 4 отправка запроса на получение веб страницы от deb-serv В строке 5 подтверждение получения данного пакета.
В строке доступ бк леон мы видим отправку ответа на запрос то есть отправку куска веб-страницы.
Вероятно из-за особенностей pcap на данном интерфейсе tcpdump видит один пакет размером в байт, в то время как в сеть уйдут 2 пакета размером и байта соответственно. Если посмотреть более подробный вывод tcpdump, то увидим, что на данном пакете точнее пакетах стоит флаг DF: Когда эти пакеты с данными доходят до deb-serv они отбрасываются, так как не могут пройти по соединению с MTU и не могут быть фрагментированы флаг DFа в ответ генерируется сообщение ICMP тип 3 код 4: В этом сообщении передается нужный MTU.
Данные пакеты доходят до deb-serv, где генерируется подтверждение, и так повторяется до тех пор, пока вся страница не будет передана. Размер всех последующих пакетов будет не больше байт.

ICMP 3: С каждым разом время между повторной посылкой все увеличивается в данных примерах я отбросил временые метки, но на самом деле так работает механизм ретрансмита TCP. Никаких данных размером большим, чем PMTU, в таком случае не передать. Я постарался представить ее в упрощенном виде на рис. Черная дыра в определении PMTU. Эта проблема совсем не нова.
Она описана в RFC в году. Но тем не менее, продолжает встречаться с завидным упорством у многих провайдеров. А ведь именно провайдер виноват в данной ситуации: Решение проблемы с PMTU Не будем звонить в техподдержку, а попробуем решить проблему, исходя из собственных средств.
