não pode ssh na máquina depois de configurar as chaves

Question

Estou tentando me conectar a um host - depois de configurar as chaves pública e privada, essa é a saída detalhada de ssh (x é o nome do host):

onde estou errado aqui? Eu posso apenas ssh nesta caixa.

Você deve referenciar a chave privada na opção -i , em vez da pública:

chronos@localhost ~/.ssh $ ssh -vvvi ~/.ssh/id_rsa freebsd@x
