Github 之 Connection timed out 的问题

Thu, 03 Jul 2025 16:49:52 +0000

最近push代码到github的时候出现了问题

$ git push origin master

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.

经过google后找到了解决办法

先用如下命令进行测试

ssh -T -p 443 xx@xx

如果测试后出现下面类似的提示说明可以继续操作了

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

接下来编辑~/.ssh/config文件（没有则创建一个），然后加入下面的代码：

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

最后在进行测试下

ssh -T xx@xxx

如果有如下提示表示可以进行正常操作了

Warning: Permanently added the RSA host key for IP address '[192.30.253.122]:443' to the list of known hosts. 
Hi yourname! You've successfully authenticated, but GitHub does not provide shell access.

github-gist-hosts 设置

最近打开gist.github.com就会出现问题，打不开，记录一个推荐的办法，很有效果

192.30.252.141 gist.github.com 
185.31.17.184 github.global.ssl.fastly.net 
185.31.17.184 github-camo.global.ssl.fastly.net

国内解决github访问慢的办法

github 慢, 或者说是它的资源 host 被堵而已, 大家可以通过简单的 hosts 映射解决:

185.31.16.184 github.global.ssl.fastly.net
