I have a synology DS that I host my sites on. Every month I have to reset my dns which is dynamic, and I use freedns.org. I have noticed that you can get scripts that do this for you automatically.
Here is an example I am thinking of trying Example script
What my questions is: where would I put this script to be running all the time?
I have looked through it and think I can do this as it looks pretty basic.
The synology is a variant of linux:
bin initrd opt sbin var
dev lib proc sys var.defaults
etc lost+found root tmp volume1
etc.defaults mnt run usr
This is the system.
