Git 子模块无法在从私有 git 服务器克隆时递归
Git submodules fail to recurse at cloning from private git server
这个问题已被问过无数次，但总是与 public git 服务器（例如 github）结合使用。我正在设置自己的私人 git 服务器，这似乎进展顺利，直到我尝试克隆一个包含我之前提交并推动自己的子模块的项目。
当针对 github 提出这个问题时，答案似乎总是需要生成密钥对并且需要使用 [=32= 注册 public 密钥]中心。我很乐意在我的私人 git 服务器上注册我的 public 密钥，但我找不到任何关于此的文档。有可能吗？甚至 git-scm.com 中的文档也进入了 git 中心参考。
我的私人 git 服务器只不过是一个 Raspberry Pi 外置硬盘 运行 Raspbian 精简版。我做了三个项目，其中一个是主项目，另外两个作为子模块添加。我可以这样创建它，提交并推送，但是当我尝试使用 --recurse-submodules （或不使用然后使用子模块 init/update）克隆它时，子模块失败。但是，我可以克隆主项目范围之外的子模块。
我一直在搞网络设置，树莓派换了好几次IP。当我因此 运行 遇到问题时，我设置了一个指向我的路由器的 DNS 条目，并向路由器中的 Pi 添加了一个端口转发规则，这样我就可以有效地从世界各地访问我的私人服务器。因为 URL 发生了变化，并且不想在某个地方留下旧 URL 的残余，所以我只是重新开始了所有三个项目，但这对我没有帮助。
这是怎么回事？以下日志已匿名。 :)
更新1：问题出在克隆子模块时的身份验证。 /var/log/auth.log 显示在克隆子模块作为主项目克隆的一部分时登录失败：

我做的场景显示了错误，而且从主项目的上下文中克隆子模块也成功了：

Using git daemon perhaps or http(s) this might work? Gonna try git daemon
git daemon has no authentication，所以不会询问密码，这意味着访问您服务器的每个人都可以克隆存储库。
I don't want everyone to be able to clone my repositories and 2: I am not sure how to set it up that you do not need a password.
如果您的服务器依赖于 SSH，您需要将您的 public 密钥 (~/.ssh/id_rsa.pub) 发布到 git@yourserver:~git/.ssh/authorized_keys: 任何克隆都不需要您输入任何密码 (假设您的私钥不受密码保护）
ssh-copy-id git@yourserver
如果您的服务器使用的是 https 服务器，那么您需要通过 Git credential storage (on a Windows client, for instance, that would be using the Microsoft GCM).
