Неудается настроить openssh c аутентификацией через rsa

1. Установил openssh с USE="pam tcpd chroot kerberos libedit skey"
2. Cгенерировал пару RSA ключей (публичный/личный) командой ssh-keygen

Generating public/private rsa key pair.
Enter file in which to save the key (/root/.ssh/id_rsa): (нажал ввод)
Enter passphrase (empty for no passphrase): (ввел ключевую фразу)
Enter same passphrase again: (ввел фразу еще раз)
The key fingerprint is:
a4:e7:f2:39:a7:eb:fd:f8:39:f1:f1:7b:fe:48:a1:09 root@localhost

4. Скопировал id_rsa.pub из ~/.ssh/ в ~/.ssh/identity
5. Скопоровал этот же файл на комп под Windows

Подключаясь из под Windows к Gentoo, Putty выдает что id_rsa.pub not a private key
