In raising this issue, I confirm the following: {please fill the checkboxes, e.g: [X]}

How familiar are you with the the source code relevant to this issue?:


Expected behaviour:

dnsmasq starts and DNS resolution is available.

Actual behaviour:

dnsmasq fails to start and DNS resolution is unavailable.

Steps to reproduce:

Switch to development branch and update.

Debug token provided by uploading pihole -d log:


Troubleshooting undertaken, and/or other relevant information:

I updated to the development branch to attempt to resolve an unrelated issue and found dnsmasq subsequently stayed down. The error received is below:

Jan 09 20:28:01 marida dnsmasq[17967]: dnsmasq: bad option at line 47 of /etc/dnsmasq.d/01-pihole.conf
Jan 09 20:28:01 marida systemd[1]: dnsmasq.service: Control process exited, code=exited status=1
Jan 09 20:28:01 marida systemd[1]: Failed to start dnsmasq - A lightweight DHCP and caching DNS server.

I had to disable FTL, enable dnsmasq, switch back to ftl master, then toggle dnsmasq/FTL again for things to work.

It looks like this is coming from #2570 if I had to guess. I am on dnsmasq 2.7.6 (which raspbian stretch reports as "latest"), and dhcp-name-match wasn't released until ~2.8, but I thought FTL was supposed to replace dnsmasq?

I am unsure if this breaking change was intended or not, but felt it warranted a report as I don't see documentation to the contrary.

With this version of Pi-Hole, dnsmasq does not run as a separate process. The dnsmasq code is embedded in pihole-FTL. What are the contents of /etc/dnsmasq.d/o1-pihole.conf (specifically line 47)?

@jfb-pihole Line 47 contains the dhcp-name-match as I tried to imply at the bottom of my post. I had originally thought it matched exactly what is in the PR I mentioned, but I just triple checked and see now that is not the case. Thanks for the follow up!

Closing as resolved. It was a typo.
