Not resolving DNS queries

Help Community Help
1

The issue I am facing:
Pi-hole does not resolve DNS queries anymore. In addition, the web interface times out, and commands like pihole status and echo ">stats" | nc localhost 4711 never output anything nor exit.

Details about my system:
I run pi-hole on a small desktop-turned-server box. The OS is Debian 10, my webserver is nginx, and the rest of the setup is standard. In fact, it has been running for years without major issues.

What I have changed since installing Pi-hole:
Pi-hole ran fine till yesterday. Today it doesn't. I have no clue why not.

I didn't change anything manually, and there were no automatic updates in the past three days. CPU load and memory usage are fine. The debug log shows some errors that are a consequence of not being able to resolve domains, and there's no socket statistic because ss is being called with a faulty parameter (but netstat says FTL listens on ports 53 and 4711 over IPv4 and v6 each). Other than that, things seem okay.

I'm probably missing something really stupid and obvious, but I can't seem to find it. I've searched up and down but nothing came up. Help me, people, you're my only hope.

Edit: Forgot to mention that I can't upload the debug log b/c I can't resolve the domain. Here's a pastebin instead:

Moderator note - debug log link removed and debug log made private.

I would start changing nameserver in /etc/resolv.conf to something else then 127.0.0.1 (e.g. 8.8.8.8) and updating Pi-hole. We made some changes lately that require versions to be "in sync" to work properly.

I followed your advice and updated, but not much has changed. Mainly, I still can't resolve DNS queries.

$ dig google.com

; <<>> DiG 9.11.5-P4-5.1+deb10u7-Debian <<>> google.com
;; global options: +cmd
;; connection timed out; no servers could be reached
$

The only difference is that the debug log now includes port information, which means the issue with ss is is gone.

Please generate a new debug log.

Did you run the above dig on your Pi device or an connected client?

New debug log:

Moderator note - debug link removed and debug log made private.

I ran dig on both the server and a connected client, with the same result.

It also looks that your Pi-hole is open to the internet:

 Aug 23 10:40:09 dnsmasq[8872]: query[ANY] peacecorps.gov from 170.150.133.253

 Aug 23 15:20:22 dnsmasq[29765]: query[ANY] peacecorps.gov from 45.183.117.242

Do you have port 53 exposed on your router, or is the Pi-hole in a router DMZ?

10

Pihole runs on a DMZ, this is intended behavior.

Here is the complete crash output (well, mostly complete, I removed a couple thousand similar lines in the middle):

A public facing DNS server likely violates the terms and conditions of your ISP or hosting solution. We at the Pi-hole project do not in any circumstance recommend, condone, or support public facing DNS with the project.

There are far too many ways someone can use it in a DNS based attack.

Companies like CF, OpenDNS, and Google have millions of dollars invested in their DNS server infrastructure to prevent this you as a one off user do not.

The recommended course of action for PERSONAL use is to use a VPN to allow use of pi-hole outside of the LAN there is a very well written guide located here

We do support non-personal use however it is on a case by case basis and should be directed towards the contact us page on https://pi-hole.net

Your server is likely crashing under the high load it experience. And with the ANY requests it looks like it is already being abused by a DNS amplification attack. You should shut it down immeadiatly.

Huh. Thank you for pointing that out, I was (obviously) not aware of the attack. I never meant for pihole to be used publicly. But I've been running the server as a DMZ for years without problems, relying on security through obscurity and getting careless.

I've now switched the router config from DMZ to single port forwarding rules. And what do you know, everything is working smoothly. Thanks again, I appreciate everyone's help.

This won't prevent an attack. It will only postpone it a bit. Get a VPN.

Dont worry, port 53 is closed. The rules are for web & mail server
