如何在Linux系统尽可能保证UCAS校园网不断连？

fiucas.sh

#!/bin/bash

while true
do
    loss_rate=$(ping www.baidu.com -c 4 | grep "packet loss" | awk -F, {'print$3'} | cut -d' ' -f2)
    if [ "$loss_rate" != "0%" ]
    then
    	nmcli conn up UCAS
      # PUT YOUR CURL COMMAND HERE 去用浏览器开发者工具的 network 面板找到提交表单的请求，copy as CURL 然后粘贴到这里
    fi
    sleep 10
done
