Перестал работать scp без пароля

[kryuch]

Добрый день. Имеется скрипт, запускаемый через cron который копирует файлы по scp, изначально все работало. Неожиданно обнаружилось, что scp начал требовать пароль, хотя прежде работал. Причем если ввести пароль, то копирование идет хорошо. С другой машины копирование на тот-же сервер также перестало работать без ввода пароля, отсюда делаю вывод, что проблема на стороне сервера. Но настройки ssh на сервере не менялись.
scp -vvv выдает следюущее

Вероятно, удалён ключ из authorized_keys.

[kryuch]

Вероятно, удалён ключ из authorized_keys.

Ключ есть.
Но на другой сервер копирование происходит нормально

[sptica]

Получается, что раньше работало по ключу, а сейчас перестало, в причинах уже Вам разбираться . Можно начать с того, что посмотреть есть на ли сервере ли ~/.ssh/authorized_keys Ваш ключ и правильные ли права доступа.

Ну и почитайте http://www.beget.ru/art_ssh_by_key со второго пункта, если у Вас уже есть сгенерированный ключ.

у вас нет секретного ключа на сервере в каталоге /data/ пригодного для идентификации данного клиента. Либо он есть, но права его неправильные (должно быть 0600)
