Gente,
Eu apenas instalei o ubuntu 16 e configurei um SSH. Eu estava depurando algo e acabei regenerando as chaves ssh, após o que ele começou a solicitar senha. Fiz alguns goggling e acabei fazendo ssh-keygen -A
executando o comando /usr/sbin/sshd -d -p 2222 deu um problema de aces, para o qual eu forneci 777 acesso a /etc/ssh/
Eu tentei regenerar as chaves ssh, mas retornei uma mensagem dizendo que a conexão foi redefinida
arjun@Arjun:~$ ssh-keygen -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (/home/arjun/.ssh/id_rsa):

The key fingerprint is:

Também alterei o PermitRootLogin para sim em / etc / ssh / sshd_config
