github网络错误处理

[root@node10 kodoe]# git pull origin:dev
ssh: Could not resolve hostname origin: Name or service not known
fatal: Could not read from remote repository.

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

1. 测试和github的连通性

   返回当前ssh-key在github上对应的用户

   ssh -T git@github.com
   Hi PoplarYang! You've successfully authenticated, but GitHub does not provide shell access.
   

2. 如果1返回的是Connection timed out

   ssh -T git@github.com
   ssh: connect to host github.com port 22: Connection timed out
   

   有可能DNS被污染，需要找到正确的解析。
