最近在给新电脑配置GitHub的ssh时，一切都是按照流程进行github上文档的配置流程进行配置，但是把公钥配置到github后，在对仓库进行操作的时候依旧出现一下提示
git@github.com's password:
Permission denied, please try again.
但是按照提示输入github密码也不行。
折腾了好久，什么把key删除重新生成，重新配置公钥，什么文件权限，把密钥配置到代理等等手段都试了，依旧不行，给我整的快怀疑人生了。
但是同样的操作在gitlab上就是正常的，看来我的操作没啥问题，应该是跟github有关系了。
后来使用
ssh -Tv git@github.com
去测试链接并且打印日志，出现以下日志

说实话也没看出来哪里有问题。
后来继续翻github文档，看到了这个
https://docs.github.com/cn/authentication/troubleshooting-ssh/using-ssh-over-the-https-port
于是尝试执行了一下
ssh -T -p 443 git@ssh.github.com
居然就成功了… 看来是所谓的防火墙问题吧
按照文档提示在config文件中添加以下内容,没有config的话自己新建一个(就在你的.ssh文件夹内)，把后缀名删掉即可。
Host github.com
Hostname ssh.github.com
Port 443
User git
然后再次运行
这样就ok了，真的是坑啊…
