Не удаётся подключится по ssh используя RSA ключ

[Angel_ok]

Подключаюсь с Windows на Debian по ssh. Просто по паролю подключается без проблем. Но с ключами не получается.
Пробовал генерировать ключи и на линуксе и на виндовс - результат отрицательный.
В путти генерирую ключ, копирую на debian в ~/.ssh/authorized_keys
выполняю:

chmod 600 ~/.ssh/authorized_keys

в windows, в putty ввожу айпи, порт, логин, указываю приватный ключ, подключаюсь и получаю:

Что я делаю не так? Как подключиться к debian используя RSA ключ?

[ihammers]

Под GNU/Linux создаёте ключ на той машине с которой хотите подключиться и потом его копируете через ssh-copy-id. После чего у вас будет доступ по ключу (если его в настройках не отключили). Под MS Windows должно быть примерно так же. Генерируйте ключ и добавляйте его на ту машину к которой хотите подключиться.

Так и делаю!
Вот сейчас сделал с линукса.
На компьютере с которого хочу подключится создал ключ:

ang@XX.XXX.XXX.XX's password:

Number of key(s) added: 1

Now try logging into the machine, with:   "ssh -p '49822' 'ang@XX.XXX.XXX.XX'"
and check to make sure that only the key(s) you wanted were added.
далее подключаюсь по ssh, но ключ не проходит, в итоге можно войти по обычному паролю
