git - ssh -vT git@github.com kex_exchange_identification : Connection closed by remote host

Question

the way I config the ssh-key, 我生成了一个新的 ssh key ，添加到我的 github 中，但是出了点问题，我尝试了很多方法，但我不能。

$ ssh -vT git@github.com

我能做什么？

我怀疑您的 ~/.ssh/ 中的 key 过多.点 ssh到您使用的确切 key 。在 ~/.ssh/config :

Host github.com
    User git
    HostName github.com
    IdentityFile ~/.ssh/id_rsa # or whatever key you use with Github

那就试试 ssh -Tv git@github.com再次。
