Não é possível conectar via sshd no linux científico 6

1

Eu tento conectar-me ao ssh na minha máquina de trabalho (na mesma rede).

A máquina é alcançável pelo ping e responde com o prompt de senha quando eu tentar ssh. Mas não aceita a senha.

Eu duplico e tropeço o nome de usuário e a senha, bem como reiniciei o serviço. Há algo que estou perdendo?

Estou tentando conectar-me a partir de uma máquina Ubuntu, caso isso seja importante.

Aqui está a saída de depuração: (dados de usuário trocados por & & (servidor) ** (cliente))

  1. marque / var / log / auth ou / var / log / secure na máquina remota e procure por erros ou avisos.
  2. use ssh -vvv username @ server e leia atentamente a saída
  3. Verifique se você não está usando uma lista de usuários permitidos.
  4. Certifique-se de que você está tentando fazer login como root e que a opção para permitir login root não está desabilitada.
  5. Verifique se a autenticação por senha está ativada e se uma chave não é necessária.

Se tudo mais falhar, imprima a saída de ssh -vvv .... ou quaisquer avisos / erros encontrados em / var / log / auth ou / var / log / secure
