ddns-start-merlin-linode

Custom DDNS script to update Linode DNS

Description

Update Linode DNS on an Asus router running Merlin firmware

Requirements

1. Install bash and jq via entware
2. Generate Linode API key, then get Domain ID and Resource ID for your A record, then modify the constants delcared at the top of the script (leave SCRIPT_NAME alone).
3. Copy the script to your router as /jffs/scripts/ddns-start and make sure it's executable. (Run dos2unix on it if you edited it using Winblows.)
4. Test it from command line, and once you're happy change DDNS to "Custom"
