是什么原因导致ssh客户端声称密码是一种可能的身份验证，但在拒绝登录之前没有提示用户输入密码？
例如：
ssh -v test@localhsot
> Authentications that can continue: publickey,password
> Next authentication method: publickey debug1: Trying private key:
> /home/ubuntu/.ssh/id_rsa debug1: Trying private key:
> /home/ubuntu/.ssh/id_dsa debug1: Trying private key:
> /home/ubuntu/.ssh/id_ecdsa debug1: Trying private key:
> /home/ubuntu/.ssh/id_ed25519 debug1: No more authentication methods to
> try.
test@localhost：权限被拒绝(公钥、密码(。
当服务器关闭密码验证时会发生这种情况
sudo grep -i password /etc/ssh/ssh_config
PasswordAuthentication否ssh-vtest@localhost…
> debug1: Authentications that can continue: publickey,password debug1:
> Next authentication method: publickey debug1: Trying private key:
> /home/ubuntu/.ssh/id_rsa debug1: Trying private key:
> /home/ubuntu/.ssh/id_dsa debug1: Trying private key:
> /home/ubuntu/.ssh/id_ecdsa debug1: Trying private key:
> /home/ubuntu/.ssh/id_ed25519 debug1: No more authentication methods to
sudo vi /etc/ssh/ssh_config
sudo grep -i password /etc/ssh/ssh_config
PasswordAuthentication是
enter code here。。。
debug1: Authentications that can continue: publickey,password
debug1: Next authentication method: publickey
debug1: Trying private key: /home/ubuntu/.ssh/id_rsa
debug1: Trying private key: /home/ubuntu/.ssh/id_dsa
debug1: Trying private key: /home/ubuntu/.ssh/id_ecdsa
debug1: Trying private key: /home/ubuntu/.ssh/id_ed25519
debug1: Next authentication method: password
test@localhost's password:
debug1: Authentication succeeded (password).
