    Você pode mostrar as permissões da sua pasta /etc/ssh com o comando ls -la /etc/ssh ?
    Ah, seria bom ver, também, as permissões da pasta ~/.ssh com ls -la ~/.ssh

  • estou com o mesmo problema... no caso eu trabalho com diversos servidores em cloud e ao tertar acessar ..

    exemplo:

    ssh -i ~/.ssh/some_key user@example.com
    Received disconnect from xx.xxxx.xx..xx port 22:2: Too many authentication failures
    Disconnected from xx.xxx.xxx.x port 22

    aí quando rodo um:

    eval "$(ssh-agent -s)"
    Agent pid 13350

    o comando SSH entra de boa
