SSH 到 GitLab 权限被拒绝（公钥、gssapi-keyex、gssapi-with-mic）

Posted 2023-02-19

【中文标题】SSH 到 GitLab 权限被拒绝（公钥、gssapi-keyex、gssapi-with-mic）

【英文标题】：SSH to GitLab Permission denied (publickey,gssapi-keyex,gssapi-with-mic)

【发布时间】：2021-09-01 04:26:20

【问题描述】：

我无法通过 ssh 连接到我们公司的 GitLab 服务器时遇到问题， 我可以轻松地从该服务器推送、拉取、克隆 repo，但是当我尝试 ssh 时出现错误， 我正在尝试在 Ubuntu VM 和我的 Windows 桌面上执行此操作，除了 ssh 到服务器之外，我都可以执行所有操作。我可以使用相同的密钥轻松地 ssh 到其他一些服务器，例如 Acquia。 感谢任何帮助

Permission denied (publickey,gssapi-keyex,gssapi-with-mic)

请注意，为了安全起见，我更改了一些不必要的细节

【问题讨论】：

根据调试输出，ssh向服务器提供了/home/oskar/.ssh/id_rsa，服务器不接受。您希望 ssh 如何对服务器进行身份验证？它应该使用什么键？

嗯，它是否出于某种原因在寻找私钥？在 Gitlab 帐户中，我添加了我的公共 SSH 密钥，在文件夹 .ssh/ 我有 id_rsa 是私钥和 id_rsa.pub 是公共的

看起来类似于***.com/questions/45130952/… >> 在那里查看我的解决方法

【参考方案1】：

我可以轻松地从该服务器推送、拉取、克隆 repo

确保您可以使用 SSH URL，而不是 HTTPS URL。

如果您在（成功）克隆存储库时确实使用了 SSH URL，请重复以进行测试，克隆：

git -c core.sshCommand="ssh -Tv" clone [e-mail]:...

这会告诉你实际使用的是什么文件。

不要忘记，与您的日志（显示 [e-mail]）相反，SSH 始终使用服务帐户 git 完成，而不是您自己的登录名。

如果您尝试ssh [e-mail]，我确认它永远不会起作用：远程服务器上没有oskar，只有技术服务帐户git（反过来，您的GitLab 有一个~git/.ssh/authorized_keys与您的公钥关联的 ID：这就是 GitLab 对您进行身份验证的方式。

【讨论】：

我确实试过了，我可以看到它正在使用我的公钥成功进行身份验证，并且它正在将选定的 repo 克隆到我的桌面，尽管当我尝试执行 ssh ssh gitlab.test-test 时。 com 我看到一条错误消息“权限被拒绝（公钥，gssapi-keyex，gssapi-with-mic）。”

@Tori 应该是 ssh [e-mail] 而不是 ssh ssh gitlab.test-test.com
