解决阿里云服务器不能 git push 到 Github

最近在 git push 推送代码到 Github 时失败，之前是可以的，错误信息如下：

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.

执行 ssh -T git@github.com 需要几十秒才响应，结果也是失败

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

查看 ls ~/.ssh 发现都存在

id_ed25519  id_ed25519.pub  known_hosts

解决方法

创建文件 ~/.ssh/config 加入配置信息，需要把 User 替换为你的 Github 的邮箱。

Host github.com
User tumobi@163.com
Hostname ssh.github.com
PreferredAuthentications publickey
IdentityFile ~/.ssh/id_ed25519
Port 443

再次执行 git push 如果出现如下错误：

Bad owner or permissions on /home/tumobi/.ssh/config
fatal: Could not read from remote repository.

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

需要更改 ~/.ssh/config 文件权限

chmod 600 ~/.ssh/config
