GitHub上传不了的解决 ssh: connect to host github.com port 22: Bad file number git did not exit cleanly (exit code 128)

问题情况

本来一直用的是github的客户端，结果现在上传的时候出问题了，去网站上看，新项目已经创建，但是代码却怎么都上传不上去。于是只好用命令行的方式解决。

Tortoisegit上是这样说的:

git.exe push -v --progress "xx" master:master

Pushing to git@github.com:xxx/xxxx.git
ssh: connect to host github.com port 22: Bad file number
fatal: Could not read from remote repository.

git did not exit cleanly (exit code 128)

gitbash上是这样说的

$ git status
On branch master
Your branch is based on 'origin/master', but the upstream is gone.
  (use "git branch --unset-upstream" to fixup)

尝试解决

通过查询，发现在bash中自己没有授权key，于是按照教程，查询现有的密钥：

ls -al ~/.ssh
clip < ~/.ssh/id_rsa.pub

将现有的id_rsa加入到github网站上,并按照github的官网给的教程，将原有的id_rsa加入到本机的ssh:

eval "$(ssh-agent -s)"
ssh-add ~/.ssh/id_rsa

但是运行ssh -T git@github.com命令还是显示ssh: connect to host github.com port 22: Bad file number

还是没有解决，然后在官网的常见问题中看到了BadFileNumber，有三种方法，1是用https，2是关于防火墙的，看起来比较麻烦，不想弄；3就是用ssh而非https
而我现在用的好像就是https啊，于是再试着用TortoiseGit试一下，还是不行。
那就用第三种方法吧，在~/.ssh/config文件中增加，但是看看只有config file而没有Config，于是就拷贝一个重命名为config，把下面的代码粘贴：

Host github.com
  Hostname ssh.github.com
  Port 443

就能出现下面的成功授权提示啦~~~

The authenticity of host '[ssh.github.com]:443 ([192.30.253.123]:443)' can't be established.
RSA key fingerprint is .
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added '[ssh.github.com]:443,[192.30.253.123]:443' (RSA) to the list of known hosts.
Hi ! You've successfully authenticated, but GitHub does not provide shell access.

再去push看看，终于成功啦啦啦啦
