![SSH 公钥认证失败 Mac OSX](https://linux22.com/image/574552/SSH%20%E5%85%AC%E9%92%A5%E8%AE%A4%E8%AF%81%E5%A4%B1%E8%B4%A5%20Mac%20OSX.png)
我正在尝试让同事的 MacBook Air 运行公钥身份验证,即使生成了新的 SSH 密钥,我也无法让它像我的一样运行。仔细检查文件权限,将她添加到服务器上所有适当的组中。配置服务器以接受公钥等。我已将她id_dsa.pub
准确地复制到~/.ssh/authorized_keys
文件中。
编辑:
我已经运行过了/usr/bin/ssh-add -K
,但也没有用。
$ ssh -vvv
产生以下调试:
macbookname:.ssh user$ ssh -vvv user@domain

我是否遗漏了什么?
答案1
以下是一些可以排除简单原因的问题?
- 连接 Air 时,您使用的用户名正确吗?
- 您确定该
authorized_keys
文件的模式为 600、该.ssh
目录的模式为 700、并且主目录除了所有者之外任何人都无法写入吗? - 服务器应该已经已配置为接受基于密钥的身份验证。如果您必须更改某些内容,那是什么?
- 您是否查看过系统日志(/var/log/system.log)以查看是否有任何相关的错误消息?
如果以上列表均无帮助,则可以使用以下快速诊断问题的方法:
- 停止 ssh 服务器。有多种方法可以做到这一点,但最简单的方法是取消选中“共享”控制面板中的“远程登录”复选框。
以 root 身份在命令行上使用标志启动 ssh 服务器
-d
。这将接受一连接并打印出大量调试信息:$ sudo /usr/sbin/sshd -d
查看调试信息中是否有任何有用的错误消息。
- 不要忘记重新启动 ssh 服务器。
如果您没有发现任何有用的信息,请在此处发布日志。
答案2
在客户端上运行ssh -vvv
以查看扩展输出并检查服务器日志。不将密钥模式设为 0600 并由用户拥有是一个常见错误。如果私钥可由其他人读取或如果 authorized_keys 可由其他人写入,则 ssh 将拒绝身份验证。
答案3
尝试运行该ssh-add -K
命令。
答案4
您可以尝试使用 Userify 分发密钥,以确保在远程主机上正确设置权限。(此外,Userify 还提供了适用于 Mac 的良好操作指南,其中包含使用技巧)。
