Вход по SSH-ключу не работает

У меня проблемы со входом на один сервер в SSH с помощью ключа

это вывод клиента: ssh 'importer@pdw.me' -p 2201 -v

и это результат на сервере (когда я начинаю с -debug)

не уверен, что здесь происходит, SSHD убивает себя, когда клиент пытается войти в систему. Это Debian 7 в контейнере openVZ (хост также Debian 7)

Вход по SSH через пароль работает нормально, я просто отключил его с целью тестирования входа в систему с помощью ключа, он всегда запрашивал пароль при попытке входа в систему с помощью ключа (поскольку ключ не работал).

Я установил% HOME% на 700, .ssh также установлен на 700, файлы внутри - на 500

Я скопировал ключ с помощью ssh-copy-id (и сделал это второй раз). Ключи, которые я использую, немного старше, поэтому я создавал их не только для этого SSH-клиента. Я не могу найти ошибок в authorized_keys

это из sshd_config

RSAAuthentication yes 
PubkeyAuthentication yes
 AuthorizedKeysFile   %h/.ssh/authorized_keys

По-прежнему получаю сбойный открытый ключ.

кстати. тем временем я пытался получить доступ к тому же серверу от другого клиента: ssh-keygen -t rsa ssh-id-copy ssh ..

и это сработало, значит, это должно быть что-то на клиенте выше
