Installing and running a Shell script on my router

[Phydeauxman]

I am completely new to customizing my router (AC1900) outside of putting Merlin FW on it. I recently moved my DNS from DynDNS over to AWS. Obviously, the router has the builtin ability to update with DynDNS but not with AWS. I found a shell script out there someone wrote to do this but not sure how to actually put this on the router and get it to run on a regular basis.

Any pointers?

Thanks for the tip. That link has some great info but I am confused. The way it reads is that those scripts should be in the /jffs/scripts folder but my folder is empty. The script I plan to use came from the site you linked...just in a different location. I read https://github.com/RMerl/asuswrt-merlin/wiki/Custom-DDNS but not sure if I fully understand. Am I supposed to create a folder called ddns-start inside the /fffs/scripts folder and then place the AWS shell script I have in that folder? Does it just automagically get executed when I set DDNS to Custom?

Yes the ddns-start script should be placed in the /jffs/scripts directory. There is nothing in that folder unless you put it there.

I've never used it myself but a cursory glance at the example AWS Route53 script looks like it should be pasted verbatim (changing the keys of course) into the ddns-start file.

The script appears to be working but it does not appear to be getting the IP address from the router. I believe th IP address should be passed into the script as $1 but when I echo that out as part of the script...it is blank. The error emails I am getting from MailGun are "There was an error updating <my-domain>.net. to IP address ."
