Dnsmasq.service could not be found

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

Expected Behaviour:

I have an android box S905X (T95X)
I installed ARMBIAN from https://yadi.sk/d/5_32km_EsCV2A/ARMBIAN/5.64/20181019
I used this dtb file : https://github.com/150balbes/Amlogic_s905/tree/535b3e013acfeb189da206d22d29a99905e3dc9d/dtb_file/S905/T95X_1g8g
pi-hole install seems to be ok and go at the end but...

Actual Behaviour:

dns service is not running
when i check dsmasq.service :
root@aml:~# sudo service dnsmasq status
Unit dnsmasq.service could not be found.
I checked log file but i don't have more information about the problem

Debug Token:

Thanks a lot !

In V4 of Pi-Hole, dnsmasq code is included in pihole-FTL and dnsmasq no longer runs as a separate process. The debug log will show dnsmasq as "inactive" or "failed", this is normal.

*** [ DIAGNOSING ]: Pi-hole processes
[✗] dnsmasq daemon is inactive

However, your debug log shows that pihole-FTL is also not running - it should be running on ports 53 and 4711.

*** [ DIAGNOSING ]: Ports in use
*:22 sshd (IPv4)
*:22 sshd (IPv6)
*:80 lighttpd (IPv4)
*:80 lighttpd (IPv6)

This causes the DNS resolution errors shown in your debug log:

*** [ DIAGNOSING ]: Name resolution (IPv4) using a random blocked domain and a known ad-serving domain
[✗] Failed to resolve adserverec.adtechus.com via localhost (127.0.0.1)
[✗] Failed to resolve adserverec.adtechus.com via Pi-hole (192.168.1.35)
[✓] doubleclick.com is 172.217.18.206 via a remote, public DNS server (8.8.8.8)

What are the outputs of the following commands run from the terminal on the Pi-Hole host:

sudo service pihole-FTL status

cat /var/log/pihole-FTL.log

sudo netstat -nltup | grep 'Proto\|:53 \|:67 \|:80 \|:471'

You are running Debian Stretch on AArch64.

What distribution are you running and what type of filesystem are you using? (EXT2/3/4 or something else?)

zetonton · October 24, 2018, 8:21am

My distribution is Armbian_5.64_Aml-s9xxx_Debian_stretch_default_4.19.0-rc7_20181019.img found here : https://yadi.sk/d/5_32km_EsCV2A/ARMBIAN/5.64/20181019
I followed this post to install it : ARMBIAN for Amlogic S905 and S905X (ver 5.44 =<) - General Chat - Armbian forum and i used this dtb file (in theory) customized for my box https://github.com/150balbes/Amlogic_s905/tree/535b3e013acfeb189da206d22d29a99905e3dc9d/dtb_file/S905/T95X_1g8g

Filesystem type is EXT4.
