How to solve this problem? There is no software using port 53. And my os is Raspbian
root@raspberrypi:/etc/init.d# ./pihole-FTL start
Not running
dnsmasq: failed to create listening socket for port 53: Permission denied
And I save my Upstream DNS Servers settings, The pihole-FTL will be offline, I must start it manually.
In V4.0, dnsmasq is embedded in pihole-FTL, and dnsmasq no longer runs as a separate process. The debug log will show dnsmasq as either failed or inactive. Process pihole-FTL should be shown running on port 53.
Please generate a debug log, upload it and post the token.
If you are unable to upload the debug log, then change the Pi nameserver as follows and then generate and upload the debug log.
sudo nano `/etc/resolv.conf`
edit `127.0.0.1` to `9.9.9.9` or your preferred third party DNS service
save and exit
My ISP Blocked the upload server , so I upload the log here.

You should use the service commands to start and stop FTL:
sudo service pihole-FTL start
sudo service pihole-FTL stop
Your debug log shows that pihole-FTL is running on port 53:

and shows that Pi-Hole is properly resolving DNS queries:

Let's double check the processes running on ports used by Pi-Hole. Please post the output of this command run from the Pi terminal:
sudo netstat -nltup | grep 'Proto\|:53 \|:67 \|:80 \|:471'

pihole-FTL process is started by manually
FTL will start when the system boots, since it's a necessary system function. If you want to only manually start pihole-FTL which is highly unadvised and not a supported runtime, then you need to stop pihole-FTL from starting on boot. Do not run ./pihole-FTL from /etc/init.d or from it's location in /usr/bin. Run sudo service pihole-FTL start or sudo systemctl start pihole-FTL only. The init scripts handle the creation of many required files and nodes that manually starting the process will not create.
I tried, and it always inform me like this below.
root@localhost:/home/user# /etc/init.d/pihole-FTL start
Not running
dnsmasq: failed to create listening socket for port 53: Permission denied
Do not run /etc/init.d/pihole-FTL start
Still output this information
root@localhost:/home/user# sudo /etc/init.d/pihole-FTL start
Not running
dnsmasq: failed to create listening socket for port 53: Permission denied
Is the Debian OS is not compatible with pi-hole? I used pihole in Ubuntu with no errors before.
There is no any original dnsmasq software exsits, and no other software listenning on port 53.
Permission is denied because pihole-FTL is not being invoked correctly. I have given you the proper procedure a few times now. Do not start the pihole-FTL with any command including the directory /etc/init.d.
Raspbian Stretch works just fine if you follow directions.
It will starts and runs the pihole-FTL process normally by manual.
After save this settings, it will execute "pihole restartdns" command, and then "pihole-FTL" will not start. So I must start it by manually.
And do "sudo service pihole-FTL start" or "sudo /etc/init.d/pihole-FTL start" will not work. It will show the information below:
dnsmasq: failed to create listening socket for port 53: Permission denied
"journalctl -xe" also shows that information above.
What is the output from sudo getcap /usr/bin/pihole-FTL
Yes. So I use sudo systemctl restart pihole-FTL or sudo /etc/init.d/pihole-FTL
They all will show that information.
If there is no other solution. I must to change the OS to Ubuntu.
It'll show pihole-FTL is Offline
