Use Proxy for Git/GitHub

Generally, the Git proxy configuration depends on the Git Server Protocol you use. And there're two common protocols: SSH and HTTP/HTTPS. Both require a proxy setup already.

SSH Protocol

When you do git clone ssh://[user@]server/project.git or git clone [user@]server:project.git, you're using the SSH protocol. You need to configurate your SSH client to use a proxy. Add the following to your SSH config file, say ~/.ssh/config:

ProxyCommand nc -x localhost:1080 %h %p

  "apps": {
    "http": {
      "servers": {
        "example": {
          "listen": [
