autenticação de chave pública não funciona com “ssh / sftp Daemon” no android

Question

Eu posso usar o meu dispositivo android usando senha. No entanto, não consigo configurar isso usando a chave pública auth.

$ ssh -vvv [email protected]
SSHD Server
debug1: Authentications that can continue: publickey,password
debug3: start over, passed a different list publickey,password
debug3: preferred gssapi-keyex,gssapi-with-mic,publickey,keyboard-interactive,password
debug3: authmethod_lookup publickey
debug3: remaining preferred: keyboard-interactive,password
debug3: authmethod_is_enabled publickey
debug1: Next authentication method: publickey
debug1: Offering RSA public key: /home/jsaak/.ssh/id_rsa
debug3: send_pubkey_test
debug2: we sent a publickey packet, wait for reply
debug1: Authentications that can continue: publickey,password

Defina o arquivo de chave e as permissões também:

root@android:/data/data/web.oss.sshsftpDaemon # ls -ald .ssh
drwx------ root     root              2016-04-04 12:08 .ssh
root@android:/data/data/web.oss.sshsftpDaemon # ls -al .ssh                                                                                                                                                                                                                     
-rw------- root     root          394 2016-04-04 11:45 authorized_keys

Alguma idéia?
