Очень долгое подключение по ssh

 ,


0

1

создал виртуальну машину, установил rhel.
при попытке подключения по ssh, после ввода пароля идет очень долгое ожидание.
не могу понять как его убрать.
Запустил ssh c DEBUG3.
Прикрепляю лог.
По timestamp можно понять какие ожидания.
После того, как подождешь и подключишься - все работает нормально.

Ситуация: недавно стало так, что если я долго (! буквально минуты полторы) ничего через консоль, подключенную по ссх, не делаю, то оно тупо виснет в хлам и не отвечет, не печатаются символы и все такое. Помогает только переконнектится. Та же шляпа если сделать подключение через ФМ — при попытке обновить список в открытой директории оно тупо бесконечно крутит картинку лоадера.

Могу я грешить на позортелеком?

Ну это вроде для отдельной темы. А так, раз всего полторы минуты смотрите tcpdump.

Кстати напомнили. Весьма давно, была подобная мистическая ситуация, только не через полторы минуты, а емнип где-то мин через 5-30 (рандомно) инактива в ssh и только для варианта подключения к удаленным сервакам (с локальными все работало). Появилось внезапно и только на одной машинке, за период существования проблемы не поменялся только кабель идущий от мелкого свича в кабинете до машинки. Т.е. и роутер менялся и кабели до кабинета («спасибо» пожару, проводка в коридоре вся сгорела) и свич меняли. Сама проблема не сильно уж и парила, редко нужно было.
Что стало решением не знаю. Два момента которые произошли, это замена(точнее установка) новой сетевки вместо встроенной и переезд в другое место. По времени это было разнесено, но когда заработало не скажу.
Итого это либо сетевка фигней страдала или все-таки кабель по кабинету. Больше тут вариантов не вижу.

Две машинки с которых я хожу — стационарник и лаптоп (лежа иногда поработать). Один по проводу, второй вифи. Потоковые аудио-видео через тот же инет и роутер легко, сутками и без проблем, а ссх на удаленку вот такой финт начало делать, ну с месяц.

Ну если это разные, то как написал выше, посмотрите сначала на tcpdump.

Ответ на: комментарий от deep-purple

ЗЫ Потоковые аудио-видео это udp для которых потеря не проблема. ssh это tcp, конкретное соединение. Тут много может быть нюансов, может и роутер фигней страдает. Кстати если с него заходить так же соединение рвется?

anc ★★★★★ ()
Ответ на: комментарий от anc

Потоковое tcp тоже есть, в первую очередь радио. Ну оно и понятно — я ж писал что соединение «замерзает» только когда через него ничего не передается (по крайней мере с моей стороны).

Да, запробую с роутера. И запробую htop запустить и выждать.

man sshd_config:
ClientAliveInterval
Sets a timeout interval in seconds after which if no data has been received from the client, sshd(8) will send
a message through the encrypted channel to request a response from the client. The default is 0, indicating
that these messages will not be sent to the client.

Ещё, как вариант, соединение может рваться со стороны фаерволла где-либо на пути.

Если tmux (он всё время что-нибудь туда сюда гоняет) запускать, то соединение живёт?

established, related соединения могут закрываться по таймауту, если в них не было активности. Я с такими настройками фаерволов сталкивался.

Ну вот, «по пути»: 1. это «домашний» роутер, 2. если серый адрес то роутер прова. На этом все. Обычно формулировку «по пути» используют для всего инета.

Ну ещё может быть шлюз в конторе, где находится сервак. IP у него, при этом может быть белым. Но он будет за фаерволлом (и контраком).

Это твое тср соединение где-то проходит через нат. роутер, который нат выполняет очищает коннтрак запись по неактивности. ... связь пропадает.

Ответ на: комментарий от deep-purple

и что? трафик через роутер растет и одмин роутера уменьшил таймаут очистки коннтрак записей по неактивности. иначе коннтрак таблица вырастает до огромных значений.
