Asus RT-AC66U DDNS with nsupdate

[amura11]

I recently installed asuswrt-merlin and I wanted to setup a custom update script to work with my bind DNS server using nsupdate. I followed the guide on git hub and created a script called 'ddns-start' in '/jffs/scripts/' and put my key file in '/jffs/configs'. I've made sure the script is runable and that I have 'Enable JFFS custom scripts and configs' set to 'yes'.

When I go to the DDNS section in the WebUI I get an error saying "Request Error. Please try again". If I try to apply the settings it just hangs saying "Applying". I've checked the system log and all I see is "rc_service: watchdog 253:notify_rc start_ddns" repeated all the time.

I tried manually running the script but I just get the error "-sh /jffs/scripts/ddns-start: not found".

I have two questions:

1. Is there anything blatantly wrong with my setup that's causing this?
2. How can I get more detailed logs?

After messing around some more I realized I can't run nsupdate manually. I assume nsupdate isn't installed by default. My question now becomes how do I setup nsupdate on merlin?

According to the Wiki, you must install these two packages from Entware:

# Tested with bash and bind-client to be installed from entware-ng
