Eu estou tentando se conectar a um servidor usando o arquivo pem privado que eu criei. Foi criado usando uma senha que eu conheço.
Está pedindo minha senha para o servidor remoto, que eu não tenho.
Eu removi as informações antigas no arquivo known_hosts:
ssh-keygen -R xx.xxx.xx.xx
No diretório que tem minhas public dems e private.pem diles, tento conectar, mas diz que as permissões são muito abertas (veja abaixo):
