无法通过 ssh 访问我的专用服务器权限被拒绝（publickey、gssapi-keyex、gssapi-with-mic）

我无法通过 ssh 访问我的专用服务器

这是“ssh -v user@server-ip”命令行的结果：

当我使用 public_key 配置 ssh 连接时发生了这种情况，我创建了 authorized_keys 文件并将我的 ssh 密钥复制到其中。

我可以修复这个问题吗或者我需要联系服务器配置文件？

答案1

我经常在服务器上检查这两个

sudo chown <username:username> /home/<username>/.ssh/authorized_keys
sudo chmod 0400 /home/<username>/.ssh/authorized_keys

答案2

如果您不禁用基于密码的身份验证，您可以尝试使用 -o PreferredAuthentications=password。

ssh -o PreferredAuthentications=password user@server-ip

然后就可以调试rsa auth了。
