Question

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

从Troubleshooting部分开始运行ssh -Tv git@gitlab.mydomain.com并获取此信息：

输出

没有这样的文件或目录

，但我的id_rsa.pub存在：

我在GitLab中将我的公钥添加到我的个人资料中：cat ~/.ssh/id_rsa.pub | clip。

我的存储库https网址是：https://gitlab.mydoamin.com:3000/web/oppis.git并且它可以工作（不确定端口是否重要），但不支持SSH。

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，当执行ssh-keygen -t rsa -C "your.email@example.com" -b 4096建议的保存密钥的路径是＆＃34;奇怪＆＃34;：/c/Users/matjaz.cof/.ssh，但文件已保存。所以我觉得这应该有效。

我发现了一些奇怪的事情：

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个文件。（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，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

防火墙出现了问题。我忘了设置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机器尝试通过外部IP地址连接到另一台LAN机器。（WIKI）

Answer 2

正如在聊天中讨论的那样，这在您的办公室是一个防火墙问题。您的防火墙可能会阻止端口22上的传出连接到其他服务器。

这是无法访问SSH服务器的主要原因，这就是为什么它可以从您的家庭网络而不是办公室工作
