Estou lutando com essa situação. Meu servidor SSH redefinir / recusar a conexão com outra máquina depois de aceitar o momento de login.
Usando 'ssh -vvv' da máquina com o usuário 'graco', recebo as seguintes informações:
ssh [email protected] -vvv

E testando isso com o localhost, recebo as mesmas informações no final.

Alguém poderia me ajudar? Agradecemos antecipadamente.
