Всем привет)
Я видно недостаточно хорошо ещё разбираюсь в Linux, если у меня возникают такие проблемы)
OpenSSH я настраиваю впервые и меня удивило его поведение.
У меня 2 компьютера. Один физический, другой виртуальная машина на VMWare. Оба подключены к одной сети. На обоих Ubuntu Server 9.04.
Физический - сервер.
Мне нужна аутентификация без пароля. Я сгенерировал ключи RSA, открытый скопировал на сервер. Установил все права, настроил конфиг, всё, как написанно в документации Ubuntu.
И вот, что для меня непонятно! Если на сервере выполнен вход под той учётной записью, под которой я логинюсь удалённо (собственно через SSH), то всё проходит идеально - ключи сравниваются, ввожу фразу, получаю доступ.
А вот если на сервере вход не выполнен вообще (никто не логинился), то при попытки удалённого соединения мне выдают Permission denied (publickey).
Для меня это не приемлемо. Что, нужно чтобы всегда на сервере был выполнен вход под нужной учётной записью?
Сдаётся мне, тут дело в правах. Но каких, точнее на что, я не знаю. Поэтому прошу вашей помощи, очень нужно с этим разобраться.
На всякий случай выкладываю:
