Eu sei que esse problema já foi discutido. Eu olhei para os outros tópicos, e não encontrei uma pergunta com o mesmo problema, espero que você possa me ajudar ...
I SSH de userA @ hostA para userB @ hostB . Ambos os hosts usam o mesmo sistema de arquivos, o que significa que a casa do usuário A é a mesma em hostA e hostB, e o mesmo acontece com a casa do usuárioB.
Agora, eu queria salvar a chave no diretório .ssh do B, para que eu pudesse acessar do A @ A para o B @ B sem uma senha, então fiz o seguinte no userA @ hostA:
ssh-keygen -t rsa -b 2048
ssh-copy-id -i ~/.ssh/id_rsa userB@hostB
echo $? ### output was 0, meaning it was successfull
ssh -v userB@hostB
E recebi a seguinte saída:

Note que eu consegui ter um acesso sem senha ao userA @ hostB, mas não ao acessar o userB ...
Alguma idéia?
Muito obrigado!
