openwrt | Lienol 's Modified OpenWrt source

im want to use lua to reset one of the openwrt`s Linux services . when i use below command in Linux directly and it works :

I wonder how to add in my basic script some commands with nano, Ctrl-O, Enter, Ctrl-X, Enter. You can see what I want at the end of the script. It is after git merge, I just need to save commit changes (formality)

The problem

During night hours, I want to turn off WIFI only WLR-9500 router. I want to accomplish this using a bash script from my synology NAS. Unfortunately I cannot install OpenWRT on my router, nor is there a timing table in there to turn wifi ON and OFF during predetermined hours.

What did I try so far

I have been fiddling around quite a lot with the curl command, but to to no avail yet. I managed to login into the router, and get the page that manages the radio ON/OFF, and this page/frame (using a web browser allows to turn of radio)

This is what the pageframe looks like:

Which is actually a subframe of this page:

The page frame (html) source from the router looks like this:

Problem: I want 2 IPs so that I can run two servers on my LAN. Apparently my ISP doesn't allow static IPs and I need to use DHCP to obtain my second IP.

What I have learned so far:

1. In order to get two distinct IP addresses with DHCP, you need two different MACs (or client IDs?)
2. You can't have two MACs on a single interface, so you need to put your internet facing interface into promiscuous mode and somehow get that traffic to a virtual interface with its own MAC.
3. Once the traffic gets to my virtual interface, I can just assign it to WAN firewall zone (OpenWRT thingie, not so important) for ez profit.

But here is the hard part: In order to separate my LAN from WAN there is by default two different VLANs configured in OpenWRT. LAN VLAN is eth0.1 and WAN VLAN is eth 0.2.

The final question is: How do I configure my system? Do I put eth0 in promisc or eth0.2 or both? Or is my premise completely wrong? How do I create the said virtual interface? Below is my ip addr extract.

I have cross-compiled the paho.mqtt.c to the so file and copy them to my lib directory in the workspace. I use the nm and readelf to check it, nothing goes wrong. But I can't use make to compile the sample client.c

$ readelf -h libpaho-mqtt3c.so

I want to convert 17/08/2021 23:42:32 to epoch but it throws me an error

We want to use Mosquitto MQTT as Message Broker on a number of OpenWRT gateways to forward "local" anonymous MQTT publications to a central RabbitMQ/MQTT cluster with authorization.

Mosquitto does not reliable forward queued messages when restarted (persistance does not work)

Running mosquitto version: 1.4.15

This is the last tested config:

I need to add my own package to the openwrt image. On the wiki of the project I found this article
I tried to follow the instructions for it, but in the end I did not manage to add my own package to the source code tree (the build ignored its presence).
Because of this, I tried to find some other way. And it turned out to be a this instruction. I followed the directions from there and compiled my own package.
But as you can see, the source code of that package does not depend on others and does not require any other build header files. Also, his Makefile completely includes instructions for compiling.
