SSH pede senha

Question

Eu já:

• Instalou o servidor
• Gerou as chaves pub / pri com -P ""
• Copiado o id_rsa.pub para authorized_keys
• ssh localhost > respondeu "sim", copiado para known_hosts
• tentou ssh localhost > > ainda pede senha

Alguma sugestão?

    

Answer 1

Tente usar ssh-copy-id . Você pode ter problemas de permissão. Este programa define as permissões adequadas.

    

Answer 2

Verifique as permissões e a propriedade do arquivo /home/hduser/.ssh/authorized_keys

Deve ser -rw------- hduser hduser

Se não, você pode corrigir isso com

chown hduser:hduser ~hduser/.ssh/authorized_keys
chmod 0600 ~hduser/.ssh/authorized_keys

Em seguida, tente se conectar ao seu host local com

ssh -i /home/hduser/.ssh/id_rsa hduser@localhost

Se ainda assim não funcionar, verifique os seus registros de autenticação recentes da sua maneira favorita,

sudo tail /var/log/auth.log
sudo cat /var/log/auth.log
sudo less /var/log/auth.log
sudo grep "Authentication refused" /var/log/auth.log
...

Procure por algo assim e pesquise na mensagem de erro que você recebe

Jan 21 09:03:11 hduser sshd[29543]: Authentication refused: ...

    

Answer 3

Verifique se, em /etc/ssh/sshd_config , você tem as seguintes configurações:

PubkeyAuthentication yes

ChallengeResponseAuthentication no

UsePAM yes

AllowUsers YOUR_USER_NAME
