GitLab 自托管 ssh 授权失败

Question

我仔细关注官方documentation 如何从 Windows 连接到自托管 GitLab（已尝试使用 VisualStudio 和 Tower）。
但是没有建立连接。

从Troubleshooting 部分我运行ssh -Tv git@gitlab.mydomain.com 并得到这个：

matjaz.cof@MatjazCof-PC MINGW64 ~

输出

没有这样的文件或目录

，但我的 id_rsa.pub 存在：

我在 GitLab 的个人资料中添加了我的公钥：cat ~/.ssh/id_rsa.pub | clip。

我的存储库 https url 是：https://gitlab.mydoamin.com:3000/web/oppis.git 并且它可以工作（不确定端口是否重要），但不适用于 SSH。

已编辑：
我知道 Windows 环境的路径很奇怪，但我不知道如何解决这个问题。此外，在执行ssh-keygen -t rsa -C "your.email@example.com" -b 4096 时，建议的保存密钥的路径是“奇怪的”：/c/Users/matjaz.cof/.ssh，但会保存文件。所以我认为这应该可行。

我发现了一些奇怪的东西：

debug1: Offering public key: RSA SHA256:w3E6UGqM5x3VniG+sKMxOJiTupmX3N4pwWPt6PW9di8 /c/Users/matjaz.cof/.ssh/id_rsa

debug3: receive packet: type 51
debug1: Authentications that can continue: publickey,password
debug1: Trying private key: /c/Users/matjaz.cof/.ssh/id_dsa

奇怪的是我有id_rsa.pub 和id_rsa 文件。 （它们是使用 GitBash ssh-keygen -t rsa -C "your.email@example.com" -b 4096 创建的）

所以我将id_rsa.pub 更改为id_rsa 并将id_rsa 更改为id_dsa。

现在我得到不同的日志（相关部分）：

不确定为什么它会尝试发送另一个私钥 (`id_ecdsa)？

Answer 1

问题出在防火墙中。我忘记设置Harpin NAT。

我的防火墙允许我连接到端口 22。我还将端口 22 路由到 GitLab 机器 IP。但是忘记设置Harpin NAT。

这意味着如果我的公共 IP 是 1.2.3.4(gitlab.mydomain.com)，我可以从除 (1.2.3.4) 之外的任何公共 IP 连接到 gitlab.mydomain.com。

路由器不知道如何处理数据包，因为 LAN 机器试图通过外部 IP 地址连接到另一台 LAN 机器。 (WIKI)

Answer 2

正如在聊天中所讨论的，这原来是您办公室的防火墙问题。您的防火墙可能会阻止端口 22 上与其他服务器的传出连接。

这是无法访问 SSH 服务器的主要原因，这也是它在您的家庭网络而不是办公室工作的原因
