linux - SSH : ssh-keygen generating rsa key, 但不工作

Question

我正在使用 ssh-keygen 并且不提供密码短语然后 key 指纹成功生成并显示。
然后我给 ssh-copy-id user@localhost 然后在提供它后提示我的用户密码状态 Number of key(s) added : 1.
现在，如果我正在执行 ssh localhost，它会再次提示输入密码。
另外，如果我执行 ssh user@localhost，它会要求输入密码。

PS:我已经使用过:ssh-add 和 sudo ufw allow 22 每次我做 ssh localhost 似乎都没有用已提示输入密码。

ssh -v localhost

Answer 1

我会检查这些:

• 确保远程 .ssh 目录和 authorized_keys 文件具有适当的权限

  • 两者都应该归你所有
  • 在 $HOME/.ssh 上的权限应该是 0700 (rwx:---:---) 和
  • $HOME/.ssh/authorized_keys 上的 0600 (rw-:---:---)

• 验证 ssh 守护进程是否允许 key 验证，即对于 openssh 服务器，其配置中应该有这一行:

  • 公钥认证是

然后在启用调试输出的情况下重新运行 ssh 命令

• ssh -v 你的主机

它将向您展示它将要尝试的身份验证方法，即

debug1:可以继续的身份验证:publickey,gssapi-keyex,gssapi-with-mic,password debug1:下一个认证方式:publickey

祝你好运! :)
