Error with dnsmasq, bad option at line 44

Hey, so I was trying to install pihole as per this guide: Securing DNS across all of my devices with Pi-Hole + DNS-over-HTTPS + 1.1.1.1 and when I got to the part of restarting the dnsmasq service I got the following error:

Job for dnsmasq.service failed because the control process exited with error code. See "systemctl status dnsmasq.service" and "journalctl -xe" for details.

So I run these services and receive the following messages:

● dnsmasq.service - dnsmasq - A lightweight DHCP and caching DNS server
   Loaded: loaded (/lib/systemd/system/dnsmasq.service; enabled; vendor preset: enabled)
   Active: failed (Result: exit-code) since Sat 2019-03-23 00:58:50 EDT; 1min 2s ago

respectively. I checked what was on line 44 of the config file and the below is the line that is causing the error.

dhcp-name-match=set:wpad-ignore,wpad

I tried the solution written here: Error Dnsmasq: bad option at line 44 of /etc/dnsmasq.d/01-pihole.conf, but it did not work.

Is this situation salvageable? If so, how?

This tutorial is outdated. We're not using the system-provided dnsmasq since over one year by now. Instead, we ship our own DNS server (pihole-FTL) which is a customized version of dnsmasq with lots of Pi-hole additions. This command is wrong:

sudo systemctl restart dnsmasq.service

Instead, try

sudo systemctl stop dnsmasq.service
sudo systemctl restart pihole-FTL.service

That seemed to work but it showed no console output. Also would the changes that the tutorial said to do to the /etc/dnsmasq.d/01-pihole.conf and /etc/pihole/setupVars.conf files actually do anything if the dnsmasq service is no longer used? If those changes would no longer have any real effect, which files should I change to produce the desired changes?

DL6ER · March 23, 2019, 6:20pm

This is expected. It would print only on errors.

Those are the correct files. You misunderstood me. We're still using dnsmasq but we're providing our own binary which provides more than "just" dnsmasq, hence, it has a different name. It uses the same configuration files.
