Pihole stopped working?


#1

It seems that the pihole stopped working, now it using the back-up DSN.

Your debug token is: afgq8gutxo


#2

What specifically stopped working? I don’t see anything major in your debug log.


#3

It’s not filtering anymore, I see the google ads for example. I think it reverts to the second (backup) DNS in my router settings.


#4

Run a nslookup flurry.com on the device that’s showing ads and the same command on the device that’s running the Pi-hole.

What are the outputs?


#5

Dnsmasq does complain about not finding some files, but according to the rest of the debug log they do exist?

May 16 10:53:27 dnsmasq[2760]: failed to load names from /etc/pihole/gravity.list: No such file or directory

#6

The device that I am using is a Windows 10 PC.

On the Pi I see:

pi@raspberrypi:~ $ nslookup flurry.com
Server: 127.0.0.1
Address: 127.0.0.1#53

Name: flurry.com
Address: 192.168.1.232


#7

What is the output on the Windows machine?


#8

Server: FIOS_Quantum_Gateway.fios-router.home
Address: 192.168.1.1

Non-authoritative answer:
Name: flurry.com
Addresses: 74.6.136.153
98.136.103.26
212.82.100.153


#9

I did try to repair the installation with -r and it seemed to work for for a while, then it started showing ads again.

Your router is set as your DNS on your windows machine (or at least a backup) and it responded to the DNS request.

Set-up only your pi address (192.168.1.232) as your sole DNS on your windows machine and test it again.


#11

Well, yes, and in the router I have changed the DNS to point to the Pi. This is needed for all the devices in the house.
Hmm, let me restart the router.


#12

Is that he only DNS there? Or do you have a backup DNS? Try leaving only the Pi-hole DNS.


#13

I have rebooted the router and it works again. We’ll see how long.

I have left one of the original DNS as the the back-up DNS in the router, for cases when the Pi would stop working, I am at work and my wife at home, calling me angrily :slight_smile:


#14

Keep in mind that running a secondary DNS (as backup- non pi-hole) will most likely have queries processed by it and this, ad block will be sporadic.


#15

Oh, really? I guess that’s what is happening?
Because now again I see ads…

LE: Tried to set the same IP:
“Redundant DNS Entries: ‘Primary’ and ‘Secondary’ values may not point to the same DNS server.”


#16

Correct, you need a different DNS server ( a secondary device running pi-hole).


#17

Shoot… Can it run on Windows :slight_smile: ?


#18

No you cannot. It only supports the following platforms:


#19

Are all the home routers this stupid?


#20

Factory firmware on consumer devices is fairly limited.

There are several options out there depending on manufacturer model that would unlock the full potential of the device …
