PyDdns

DDns script for dnspod.cn and written in Python3

Install

Write for router(Openwrt/LEDE), but it could be used in any Linux machine

Prepare your router

1. opkg update
2. install python3: opkg install python3
3. install pip:
   • download https://bootstrap.pypa.io/get-pip.py
   • install python get-pip.py
4. install requests: pip install requests

Prepare python file

1. in ddns.py file

ID = ""  # your ID
TOKEN = ""  # Your Token
DOMAIN_NAME = "" # your domain
SUB_DOMAIN = "" # your sub domain

2. upload file to router
3. create a file in /etc/ppp/ip-up.d ,and add python3 /root/script/ddns.py > /tmp/log/dnspod.log to file. DO NOT USE crontab!
4. chmod 777 /etc/ppp/ip-up.d/<your_script_name>

Why not crontab?

Dnspod.cn declare a limitation that every user can only upload 5 times in an hour if remote IP address and local IP address is same.

They also sugget that build a script when you create a new dial-up connection, run the script to update your IP address.

So it is in /etc/ppp/ip-up.d folder, that every time you use pppoe to connect to the Internet and you will receive a new IP address. Then every time pppoe runs, the OS will run every script in /etc/ppp/ip-up.d folder.

Future plan

1. move all personal parameters to a config file.
2. simplify code
