解決學校服務器流量問題方案

解決學校服務器流量問題方案

服務器版本

Ubuntu 16.04.4 LTS (GNU/Linux 4.15.0-36-generic x86_64)

問題

校園網流量不夠用，使用ipv6免流量上網

解決方案

kcptun + ss + proxychains

使用方法

1. 文件下載

下載後目錄文件，上傳至服務器

2. kcpwen目錄介紹

config爲配置文件，包含kcptun配置文件，ss配置文件

kcptun.json

此配置文件直接在使用kcptun加速的vps上獲取，我們這裏使用vps服務器的ipv6地址，
本地代理端口爲1086，需要與ss本地端口匹配，與proxychains代理端口匹配

{
  "localaddr": ":1086",
  "remoteaddr": "[2001:19f0:xxxx:xxxx:xxxx:xxxx:xxxx]:29900",
  "key": "xbw12138",
  "crypt": "aes",
  "mode": "fast3",
  "mtu": 1350,
  "sndwnd": 512,
  "rcvwnd": 512,
  "datashard": 10,
  "parityshard": 3,
  "dscp": 0,
  "nocomp": false,
  "quiet": false
}

ss.json

{
    "server":"127.0.0.1",
    "local_address": "127.0.0.1",
    "local_port":1080,
    "server_port":1086,
    "password":"xbw12138",
    "timeout":300,
    "method":"aes-256-cfb"
}

ipv6.py

校園網登錄腳本，例如
登錄 python ipv6.py login S20186184X 123456
註銷 python ipv6.py logout

ipv6.sh

整合一鍵啓動
./ipv6.sh
輸入網關賬號密碼直接進行網絡連接

kcptun

kcptun客戶端
./kcptun -c config/kcptun.json

log

日誌

3. proxychains目錄介紹

配置文件在src/proxychains.conf中配置
使用方法
./proxychains4 -q -f src/proxychains.conf wget www.baidu.com
可以使用別名代替，例如

vim ~/.bashrc
在文件最後追加

alias pc='/home/bowen/ipv6/proxychains/proxychains4  -q -f /home/bowen/ipv6/proxychains/src/proxychains.conf'

source ~/.bashrc

之後就可以直接使用 pc wget www.baidu.com

4.一鍵啓動

kcpwen/ipv6.sh

Code
