GitHub 之 the authenticity of host ... can't be established

今天晚上在搞github仓库..可是死活不能和github联系起来。

报了这个错：

$ git push -u origin master
The authenticity of host 'github.com (192.30.252.128)' can't be established.
RSA key fingerprint is 16:27:ac:a5:76:28:2d:36:63:1b:56:4d:eb:df:a6:48.
Are you sure you want to continue connecting (yes/no)?
Host key verification failed.
fatal: Could not read from remote repository.

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

就是这个东西。搞死我了。。

不能和github联系在一块儿。

最后发现是本身小白了....

结果就能够了...哎..记录一下本身的经历..
