`addn-host` to block some websites does not work

Installing and Using OpenWrt Network and Wireless Configuration
1
  1. On FreshTomato, I was able to specify an entry in addn-host of dnsmasq to a file that poisons some DNS records, e.g. 0.0.0.0 facebook.com
  2. After updating this file, I always run service dnsmasq restart and it works
  3. I did the same on OpenWrt, but ping facebook.com on the router still gave me the real IP address
  4. Any idea why?
2
  1. router uses upstream DNS, not the one on the router ?
3

Is there a way I can run a few simple commands to poison and unpoison the records?

4

In the GUI: Network > DHCP and DNS > General:
under addresses add /facebook/#

thanks that worked, but I have quite a few FQDNs to block... and I forgot to mention earlier

  1. After blocking, I tested resolving on my Windows and it returned the real IP
  2. Thinking it might be the cache or something, I went to the router and try, it still returned the real IP
  3. That was how I concluded additional hosts did not work
  4. Actually I don't care if router can reach the FQDNs
  5. What matters is that my clients, e.g. Windows/Linux cannot reach the blocked FQDNs

Will additional hosts files work if i ignore the resolv file?

Yes, Ignore resolv file made my Addtional hosts files work

you can use the adblock package with a custom block list.

I tried that, but wasn't able to script it.

And on a separate note, resuming and suspending adblock is super slow, /etc/init.d/adblock status does not update until almost after 1 min

there are at least two or three adblock packages, but I can imagine the status doesn't update until all the default block lists have been DLed and crunched by the addon.

No, that's not what I meant.

Okay, so I have a switch on my HomeAssistant (HA) that when toggled will turn on/off ads by performing a SSH into the router. HA also connect separately to the router to retrieve the actual status of adblock.

The HA switch can't work coherently when there is a 1 min delay from telling it to suspend until it reports that it has suspended itself.

  1. After some further debugging, Additional Hosts Files expects a folder, not file
  2. When given a path that has some host files, addn-host works reliably
