当我尝试通过 SFTP 进入我的服务器时
debug1: Authentications that can continue: publickey,password
Permission denied, please try again.
即使我使用了正确的密码。
我尝试连接的服务器的 SSHD_CONFIG。

我可以很好地将 putty 放入盒子中，但是当我从另一个盒子尝试 ssh -p 25595 user@WhereImTryingToConnect 时，它不起作用。两个盒子都是 ubuntu 14.04
编辑 1：我已将 PasswordAuthentication 从否更改为是，并重新启动了 ssh 服务。但是当我尝试 sftp -v -v -v -p[电子邮件保护]25595.我仍然收到错误
debug1: Authentications that can continue: publickey,password
Permission denied, please try again.
我尝试了 2 个不同的用户，可以验证两个密码均输入正确
编辑 2：我已经从盒子 b（试图连接的计算机）和盒子 a（我正在连接的计算机）获取了 ssh，首先我在盒子 b 上生成了一个密钥。然后尝试将密钥复制到盒子 a，出现错误提示
bash: line 2: .ssh/authorized_keys: Permission denied
所以我的第一个想法是，盒子 a 上的权限搞错了。（尽管我分别将它们设置为 700 和 600）然后我将 ~/.ssh 设置为 777（这很糟糕，不要这样做），并且我还将 ~/.ssh/ 设置为 777（同样糟糕）。这样我就能够将我的 ssh 密钥从盒子 b 复制到盒子 a。我现在还可以从 B 远程访问盒子 A。但我仍然无法从 b 通过 SFTP 进入盒子 a...

与 askubuntu 上的答案相同：
您需要在您的 中设置PasswordAuthentication yes而不是。PasswordAuthentication nosshd_config
