ssh: connect to host github.com port 22: Connection timed out

主要是更改一下ssh的端口，由22改为443

1. 进入.ssh下
2. 新建config文件
3. 添加以下内容

4. Host github.com
   User git
   Hostname ssh.github.com
   PreferredAuthentications publickey
   IdentityFile ~/.ssh/id_rsa
   Port 443

   Host gitlab.com
   Hostname altssh.gitlab.com
   User git
   Port 443
   PreferredAuthentications publickey
   IdentityFile ~/.ssh/id_rsa

    

5. 进入项目根目录，打开cmd，输入ssh -T git@github.com（如果遇到啥选项或者问题什么的，选yes就行了），最后出现Hi xxx! You've ......就可以了。

   ssh -T git@github.com

   Hi xxxxx! You've successfully authenticated, but GitHub does not
   provide shell access.

6. 再次尝试push/pull项目即可
