Adblock-lean: set up adblock using dnsmasq blocklist

Wizballs · February 23, 2024, 9:30pm

Cool. Was that just a reboot, or did you change compression config also?

ninjanoir78 · February 23, 2024, 9:32pm

both, should I put ''1'' again? (enable)

Wizballs · February 23, 2024, 9:33pm

Would you mind trying that as "1" again. Just so we know if it was the reboot or config that fixed it.

Weird, must be something to do with left over config as mentioned. At least you can run with compression=0

ninjanoir78 · February 23, 2024, 9:53pm

I don't know cause as I said, adblock is really gone

Lynx · February 23, 2024, 10:03pm

Output from running:

?

ninjanoir78 · February 23, 2024, 10:09pm

you mean, etc/init.d/adblock-lean.....?

Lynx · February 23, 2024, 10:11pm

Nah just ‘service’. I’m thinking you still have the adblock service running?

I just saw that adblock-lean is disabled, ...... everything was ok 10 minutes ago on status command

So to be clear when you have compress blocklist enabled and issue service adblock-lean start then you see dnsmasq errors on logread?

Can you add ‘ls -alh /tmp/dnsmasq.d’ here:

github.com

lynxthecat/adblock-lean/blob/9de4b1ba855a76306ec977146d61e22e4af8d963/adblock-lean#L352


      
          		log_msg "The dnsmasq --test on the processed blocklist failed."
          		return 1
          	fi
          
          	return 0
          }
          
          check_dnsmasq()
          {
          	log_msg "Checking dnsmasq instance."
          
          	if ! pgrep -x dnsmasq &> /dev/null
          	then
          		log_msg "No instance of dnsmasq detected with new blocklist."
          		return 1
          	fi
          
          	for domain in google.com amazon.com microsoft.com
          	do
          		if ! nslookup "${domain}" 127.0.0.1 &> /dev/null 
          		then

Then rerun?

The output from logread suggests the extract script isn’t there for some reason.

I’m wondering if there is some remnant of adblock or hotplug script that’s scrubbing the dnsmasq folder on restart.

ninjanoir78 · February 23, 2024, 10:52pm

something like that?

root@OpenWrt:/tmp# cd dnsmasq.d
root@OpenWrt:/tmp/dnsmasq.d# ls
root@OpenWrt:/tmp/dnsmasq.d# ls -alh
drwxr-xr-x    2 root     root          40 Feb 23 17:21 .

Need to see that from when script is running. Maybe easiest if we hop on IRC and I can guide you through some diagnostics and figure out what the issue is. I’ll be available from circa 10am UK time.

ninjanoir78 · February 24, 2024, 4:29am

dont know why it is always on stop in servive

Usage: service <service> [command]
/etc/init.d/adblock-lean      	   enabled	   stopped
/etc/init.d/avahi-daemon      	   enabled	   running
/etc/init.d/banip             	   enabled	   running

I did;

enable, start

and still on stop.

also status seems to be good;

root@OpenWrt:~# /etc/init.d/adblock-lean status

Wizballs · February 24, 2024, 7:29am

That's normal. It runs once on boot, and then on schedule from the cron tab. The service stops in between runs.

Lynx · February 24, 2024, 8:01am

Which OpenWrt version are you running?

Please could you edit the adblock-lean service file and place:

ls -alh /tmp/dnsmasq.d

at exactly this line:

github.com

lynxthecat/adblock-lean/blob/9de4b1ba855a76306ec977146d61e22e4af8d963/adblock-lean#L378


      
          			return 1
          		fi
          	done
          	
          	return 0
          }
          
          restart_dnsmasq()
          {
          	log_msg "Restarting dnsmasq."
          
          	/etc/init.d/dnsmasq restart &> /dev/null
          	
          	for i in $(seq 1 60)
          	do
          		nslookup localhost 127.0.0.1 &> /dev/null && break
          		sleep 1;
          	done
          
          	log_msg "Restart of dnsmasq completed."
          }

Then run a start and paste the output here.
