git push时出现ssh_dispatch_run_fatal

问题：gitpush遇到一下错误：

ssh_dispatch_run_fatal: Connection to 52.74.223.119 port 22: Software caused connection abort
fatal: Could not read from remote repository.

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

原因：dns解析的问题

打开cmd输入ping命令查看github.com的连接，请求超时：

解决方法：配置本地hosts文件

找C:\Windows\System32\drivers\etc\hosts，
在末尾添加上下面这段文字，保存

192.30.255.112  github.com git 
185.31.16.184 github.global.ssl.fastly.net

结果：成功解决

再次ping github.com，成功ping通。
再次Push，成功。
