背景
git 推送/拉取代码到github仓库时发生错误。
- git push
ssh: connect to host github.com port 22: Operation timed out
fatal: Could not read from remote repository.
Please make sure you have the correct access rights
and the repository exists.
- git clone
致命错误：无法访问 'https://github.com/ldf-fan/ldf-blog.git/'：Failed to connect to github.com port 443 after 75002 ms: Couldn't connect to server
问题处理
查看ssh链接
ssh -T git@github.com
报错：端口连接超时。
ssh: connect to host github.com port 22: Connection timed out
后续流程
找到.ssh文件夹，Mac中路径是 ~/.ssh，新建一个config文件，不带后缀。
touch config
打开config文件，添加下列代码，注意User后面的邮箱改为你的邮箱。
Host github.com
User xxx@163.com
Hostname ssh.github.com
PreferredAuthentications publickey
IdentityFile ~/.ssh/id_rsa
Port 443
再次执行下面代码：
ssh -T git@github.com
显示下面提示：
The authenticity of host '[ssh.github.com]:443 ([20.200.200.100]:443)' can't be established.
ECDSA key fingerprint is SHA256:XXXXXXXX/XXXXXX/XXXXXXX.
Are you sure you want to continue connecting (yes/no/[fingerprint])? yes
Warning: Permanently added '[ssh.github.com]:443,[20.200.200.100]:443' (ECDSA) to the list of known hosts.
再次执行：
ssh -T git@github.com
回应下面消息，说明成功了。
Hi xxx! You've successfully authenticated, but GitHub does not provide shell access.
接下来就可以正常推送代码了。
