DNSPod DDNS update script for Asuswrt-Merlin

Read this in other languages: English, 简体中文.

1. Download the ddns-start script to /jffs/scripts/.

   wget https://raw.githubusercontent.com/huxuan/asuswrt-merlin-ddns-dnspod/master/ddns-start -P /jffs/scripts/

2. Modify the parameters in the script accordingly. More detailed information please refer to the Parameter Specification.

3. Last but not least, ensure the script is executable.

   chmod +x /jffs/scripts/ddns-start

1. DDNS_DOMAIN

   The domain name without subdomain, e.g., example.com.

2. DDNS_SUB_DOMAIN

   Only the subdomain part, e.g., www.

3. DNSPOD_LOGIN_TOKEN

   The token for authorization to modify the DNS record on DNSPod. Note that it is a combination of ID and Token, so it looks like 13490,6b5976c68aba5b14a0558b77c17c3932.

4. DNSPOD_RECORD_ID

   The ID of the DNS record. Just fill the following command with the proceeding parameters and the record ids (only one usually) will return.

   This is a one-time effort so I pick it out intentionally so as not to run it every time within ddns-start script.

   curl -x POST https://dnsapi.cn/Record.List \
   -d login_token=<YOUR_DDNS_LOGIN_TOKEN> \
   -d domain=<YOUR_DDNS_DOMAIN> \
   -d sub_domain=<YOUR_DDNS_SUB_DOMAIN> \
   -d format=json

5. DNSPOD_RECORD_LINE_ID

   The allowed line's ids for the domain's DNS record. This is mostly used for dynamic DNS policy for different ISPs, for general usage, just use the default value 0.
