Github拉取项目报错解决

article 2025/1/5 18:13:46

前言

昨天在拉取github上面的项目报错了，有好几个月没用github了，命令如下：

git clone git@github.com:zhszstudy/git-test.git

报错信息：

ssh: connect to host github.com port 22: Connection timed out
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

我重新设置github上的ssh key，梯子也开了还是报这个错，换成https链接拉取也报错，查阅资料发现，此错误信息为不能通过 22 端口连接到 GitHub

解决方法

执行以下命令：

ssh -T git@github.com

如果出现连接超时就意味着不能通过22端口连接：

ssh: connect to host github.com port 22: Connection timed out

将 SSH 连接的端口更改为 443：

ssh -T -p 443 git@ssh.github.com

出现以下信息，表示通过 443 端口成功进行了身份验证，但 GitHub 不提供 shell 访问权限：

Hi xxxx! You've successfully authenticated, but GitHub does not provide shell access.

如果出现以下信息，则需要回复yes，如果输出上面的信息表示成功：

The authenticity of host '[ssh.github.com]:443 ([20.205.243.160]:443)' can't be established.
ED25519 key fingerprint is SHA256:+DiY3wvvV6TuJJhbpZisF/zLDA0zPMSvHdkr4UvCOqU.
This key is not known by any other names.
Are you sure you want to continue connecting (yes/no/[fingerprint])?
Host key verification failed.

在密钥目录下新建文件config，编写配置覆盖 SSH 设置：

Host github.com
  Hostname ssh.github.com
  Port 443

在这里插入图片描述

重新执行以下命令：

ssh -T git@github.com

出现以下信息表示成功：

Hi xxxxx! You've successfully authenticated, but GitHub does not provide shell access.

重新拉取项目，可以看到已经拉取成功了：

$ git clone git@github.com:zhszstudy/git-test.git
