“ssh -vT git@github.com”导致错误“kex_exchange_identification：连接被远程主机关闭”

Question

我配置 SSH 密钥的方式是生成一个新的 SSH 密钥，并将其添加到我的 GitHub 帐户，但出现了问题。我尝试了很多方法，但无法修复。

ssh -vT git@github.com

输出：

我能做些什么？

我怀疑你的钥匙太多了~/.ssh/。指向ssh您使用的确切键。在~/.ssh/config：

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

然后再试ssh -Tv git@github.com一次。
