结合json-rpc接口，配置好就能用。挺方便。

国外很多大盘鸡都装了这东西。下载文件用。
两种加密方式：
1， user password
2， token:设置的secret
如果没设置的话，就是匿名登录。

#coding:utf-8
#!/usr/bin/env python


import time
import requests
import re
import sys

file_list=sys.argv[1]

data = '{"jsonrpc":"2.0","method":"aria2.getGlobalOption","id":1,"params":[]}'

with open(file_list, "r") as f:
    url_list= f.readlines()
    for ip in url_list:
        ip=ip.strip()
        url="http://"+ip+":6800/jsonrpc?tm="+str(int(time.time()))
        response = requests.post(url,data=data)
        html = response.content.decode('utf-8')
        headers = response.headers
        if(re.findall("Unauthorized",html)):
            pass
            #print(ip+" Aria2 Unauthorized\n")
        else:
            print(ip+" Anonymous Login Vul\n")

在以前的基础上精简了一下

#!/bin/sh

name=`basename $0 .sh`


function killv2() 
{
        pid=`ps -ef | grep v2ray | grep -v grep | awk '{print $2}'`
        kill -n 9 ${pid}
}

case $1 in
 us1|us2|us3|jp1|jp2|jp3|ru1|hk1)
        echo "start ${1}..."
        killv2
        nohup ./v2ray --config=v2ray_$1.json >/dev/null 2>&1 &
        ;;
        
 *)
        echo "Usage: sudo $name.sh [us1|us2|us3|jp1|jp2|jp3|ru1|hk1]"
        exit 1
        ;;
esac
exit 0

import itertools
>>> l = [(k, len(list(g))) for k, g in itertools.groupby('0000000000000')]
>>> len(l)
1
>>> l = [(k, len(list(g))) for k, g in itertools.groupby('0000000000001')]
>>> len(l)
2

(d)1{位数,} 也可以

禁用的话，
Firefox：

about:config
media.peerconnection.enabled -> false

Chrome:

 扩展WebRTC Leak Prevent, WebRTC Control, or Easy WebRTC Block.
