Дабы не оффтопить в других темах, решил создать эту. Прошу модераторов её закрепить в шапке, т.к. после обновлений Entware у людей бывают всякого рода поломки. Предлагаю их освещать и решать здесь.

у меня тоже не работает, но вариант на nginx.

1. до решения проблемы, откатиться к предыдущей версии (ваш КО)

2. т.к. сломана Basic-авторизация (см. ниже), закомментировать/удалить связанные с ней строки в конфиг(-е,-ах) (спасибо, Кэп!)

запускаем сервис и цепляемся strace`ом к pid`y 


~ # ps | grep ext-ui | grep -v grep
 9042 root     19940 S    nginx: master process nginx -c /opt/etc/nginx/ext-ui.conf
~ # 
~ # strace -ff -v -e openat -p 9042
strace: Process 9042 attached

пробуем зайти по IP:88/ext-ui... после облома, смотрим выхлоп:

Привет. После обновления Entware столкнулся со следующей проблемой, регулярность которой не могу отловить.

Entware установлена на флешке, после перезагрузки роутера всё работает штатно, но через невыявленый промежуток времени нет возможности авторизоваться в Entware по ssh. Ошибка - Network Connection Refused.

Входить пытаюсь из локальной сети. на SSH именно роутера входит нормально, сама Entware тоже работает штатно, так, как Cron-задания отрабатывают. Если скажем через веб-морду роутера передёрнуть компонент OPKG, какое-то время входить будет возможно, но потом опять вход по ssh закрывается. В журнале роутера ничего не пишется. Вопрос как можно диагностировать проблему?

Приложений и сервисов много установлено? Или соединений? Памяти свободной сколько? Если войти не удается, скорее всего убивается сервис ssh. Изначально в качестве оного установлен dropbear. Вылетать может как сам по себе, так и при нехватке памяти он может убиваться механизмом OOM Killer.

Процессов абсолютно не много, загрузка ЦП в диапазоне 4-15%, память 22% (56/256 Мбайт).

Я тоже  думаю что умирает сервер ssh, но вот подтвердить или опровергнуть не могу. Можно ли включить лог Entware? Ну или как сделать чтоб ssh не умирал?

Можно попробовать вместо пакета dropbear пакет openssh-server.

И добавить раздел свопа, swap.

Попробуйте поставить пакет syslog-ng.

Это не из-за обновления проблема. Она всегда появляется спустя некоторое время. Даже если не обновляться (я имею ввиду "сознательно не обновляться" - может он тихо сам себе и обновляется)

Я в этой ветке продолжу эту тему обсуждать https://forum.keenetic.com/topic/2518-entware-3x-проблемы-с-установкой-настройки/page/18/#comments

У меня ssh (dropbear) на кинетиках не отваливается. Но на всякий случай держу два ssh сервера на разных портах - dropbear и openssh-server. Это может помочь с диагностикой.
