Eu tenho tentado o meu melhor para configurar o meu servidor ssh, embora toda vez que eu tento efetuar login com autorização de chave pública, ele aparece com uma assinatura de chave pública recusada pelo Servidor apesar de aceitar a chave.
Eu usei ssh-keygen para gerar um par de chaves e, em seguida, carreguei a chave pública nas authorised_keys e enviei a chave privada para a outra conta, convertendo-a usando putty.
Infelizmente, tentei o meu melhor para percorrer os registros, mas nada acontece. Por favor, ajude se possível:
