Tentei configurar chaves públicas e privadas em dois computadores (clementine e cfmi) para poder fazer ssh entre eles sem usar senha. No entanto, ainda estou sendo solicitada uma senha, apesar da inclusão da chave pública no arquivo de chaves autorizadas em ~/.ssh.
Posso fazer login no servidor cfmi quando tento me conectar a partir do clementine, mas minha senha é solicitada.
Também pode ser relevante que eu deva primeiro me conectar a uma rede VPN usando o Cisco AnyConnect e só então posso fazer ssh no cfmi, já que ele tem firewall.
No entanto, quando tento me conectar do servidor cfmi ao clementine, uma senha é solicitadaque não corresponde à senha rootEu tenho naquele computador. Portanto, não consigo fazer logon do cfmi para o clementine.
Fica ainda mais misterioso... A senha root funciona perfeitamente quando estou fazendo ssh do meu iphone na rede local.
Alguém pode me ajudar a descobrir como fazer as chaves funcionarem e como redefinir minha senha para ssh no Clementine?
EDIT: Alterado o nome das chaves ssh para id_rsa, ainda com problemas.
Aqui está o conteúdo de .ssh no cliente (cfmi):
-rwx------. 1 se394 mriusers 1634 Sep 29 22:00 authorized_keys
-rwx------. 1 se394 mriusers 1633 Sep 29 22:00 authorized_keys~
-rw-------. 1 se394 mriusers 1675 Sep 29 21:17 clementine
-rw-r--r--. 1 se394 mriusers 415 Sep 28 19:52 clementine.pub
-rw-------. 1 se394 mriusers 1679 Sep 29 22:04 id_rsa
-rw-r--r--. 1 se394 mriusers 415 Sep 29 22:04 id_rsa.pub
-rw-r--r--. 1 se394 mriusers 1830 Sep 28 20:15 #known_hosts#
-rw-r--r--. 1 se394 mriusers 1043 Sep 29 00:13 known_hosts
-rw-r--r--. 1 se394 mriusers 1837 Sep 28 17:41 known_hosts~
E aqui está a saída detalhada para cfmi conectando-se ao clementine

Verifiquei o arquivo autorizado_keys no servidor e a chave corresponde a id_rsa.pub. Alguém tem alguma dica de como proceder a partir daqui?

Você não deveria ter renomeado seu arquivo de chave privada ( id_rsa) sem configurá-lo sshpara saber quais outros nomes de arquivo ele deveria procurar ao procurar por chaves privadas.
