I use Ubuntu’s Uncomplicated firewall because it is available on Ubuntu and it's very simple.

Install UFW

if ufw is not installed by default be sure to install it first.

1.同一台电脑可以有2个git账号（不同网站的）

首先不同网站，当然可以使用同一个邮箱，比如我的github，gitlab，bitbucket的账号都是monkeysuzie[at]gmail.com 这时候不用担心密钥的问题，因为这些网站push pull 认证的唯一性的是邮箱比如我的windows 上 2个账号一个gitlab 一个github （用的都是id_rsa）

host github
  hostname github.com
