FTL And DNS Not Starting (Other Solutions Didn’t Work)

Abhijeet_Ghosh · August 8, 2020, 1:02am

Please follow the below template, it will help us to help you!

Expected Behaviour:

FTL and dns start normally and dns works.

Actual Behaviour:

After changing the cache size of pi hole, the FTL and dns service stopped. I saved the config with teleporter, then deleted pi hole using the command sudo rm -rf /etc/.pihole /etc/pihole /opt/pihole /usr/bin/pihole-FTL /usr/local/bin/pihole /var/www/html/admin . Then I fresh installed pi hole with curl -sSL https://install.pi-hole.net | bash . FTL and DNS still didn’t work, so I deleted it and reinstalled it with the git clone method. Same problem. Many people experienced this, but none of those threads solutions worked for me. Now I have no pi hole!

Used the official installation instructions found here

https://github.com/pi-hole/pi-hole/#one-step-automated-install

Debug Token:

Where in Pihole d will I find this?

Why did you do this, and how did you do this?

Abhijeet_Ghosh · August 8, 2020, 1:23am

@jfb I thought more cache would be faster dns on most used websites

I edited cache value in here

/etc/dnsmasq.d/01-pihole.conf

See this guide :

There is no benefit in enlarging this number except if the DNS cache evictions count is larger than zero.

What is the current status of your Pi-hole? Installed? Not working? Can you generate a debug log and upload it?

Abhijeet_Ghosh · August 8, 2020, 2:55am

@jfb I still thought to give it a shot because others did too

Here is my debug link https://tricorder.pi-hole.net/sc1bwbmpyh

Pi hole is currently installed fresh 5.1.1, with FTL and web ui at 5.1

The dns service and FTL service will not start

Ui looks like this:

Please run the following from the Pi terminal and post the outputs of the last one:

sudo service pihole-FTL restart

sudo service pihole-FTL status

That line is cut off in your output, but likely completes to Illegal repeated keyword

Run on your Pi-hole machine, what's the output of:

grep -nRv '^#\|^$' /etc/dnsmasq.*

jfb · August 8, 2020, 4:20pm

Also, please post the output of

pihole-FTL dnsmasq-test

Abhijeet_Ghosh · August 8, 2020, 8:07pm

Result is

dnsmasq: illegal repeated keyword at line 32 of /etc/dnsmasq.d/01-pihole.conf.save

01-Pihole.conf.save is

Big comment that states that it will be overwritten , then

Please edit your post to include the result of the grep statement I've provided above. That will help us find the conflicting duplicates.

EDIT: Dan spotted the offending file anyway - just follow his instructions to fix it.

DanSchaper · August 8, 2020, 8:14pm

Any file in /etc/dnsmasq.d/ will be read and used. Not just .conf files. So your .save will be read and used. So move that file somewhere else.

Abhijeet_Ghosh · August 8, 2020, 8:15pm

Sorry didn’t see it!

Abhijeet_Ghosh · August 8, 2020, 8:22pm

@DanSchaper @Bucking_Horn jfb (not tagged from limit)
JFBs test

Gave me insight into the problem. I deleted both the conf and conf.save and fully uninstalled pihole after teleporting the config using this command sudo rm -rf /etc/.pihole /etc/pihole /opt/pihole /usr/bin/pihole-FTL /usr/local/bin/pihole /var/www/html/admin . Then reinstalled pihole using the curl simple method, and it works!

Thanks to all who took their time to help me!

deHakkelaar · August 8, 2020, 8:24pm

Was just about to reply that pihole-FTL will read both files at boot/start:

/etc/dnsmasq.d/01-pihole.conf

&

/etc/dnsmasq.d/01-pihole.conf.save

The later doesnt belong to Pi-hole.

deHakkelaar · August 8, 2020, 8:55pm

Solution was already in previous posting
