Error when starting FTLDNS

Michl · April 3, 2018, 8:32pm

Hi, I just ran the commands to activate FTLDNS. The blocking seems to work but at the Query Log it only shows "processing" but no data. There is an error meassage within after the command to see if it works:

root@DietPi:~# sudo systemctl status pihole-FTL

I have to say that also the following update command did not work:
dietpi-update = Run now to update DietPi (from v6.1 to v6.6).

can someone help? Thanks, Michl

Run pihole -d for a debug token.

Hi have a nearly similar problem, i uploaded my token : 28n8vxvbko

I ran the command

echo "FTLDNS" | sudo tee /etc/pihole/ftlbranch
pihole checkout core FTLDNS
pihole checkout web FTLDNS

Then when i check the status of dnsmasq it still running e.g. Active(running)
And pihole-FTL is Active (exited) :

pihole-FTL.service - LSB: pihole-FTL daemon
Loaded: loaded (/etc/init.d/pihole-FTL; generated; vendor preset: enabled)

Could somebody knows what happen ?
Thanks

Your debug token is: fv3ozvplxy

DL6ER · April 4, 2018, 10:06am

Can you confirm that this means something like "No such file or directory"? If so, then this is not a critical error and maybe actually to be expected on the first run of FTL.

From your debug log it seems like pihole-FTL is running perfectly fine for you! What is the issue? Have you tried Ctrl+F5 (force refresh) in the browser?

DL6ER · April 4, 2018, 10:09am

FTLDNS is your new resolver, i.e. if name resolution works, the daemon works as well. Have you tried a force refresh in your browser (Ctrl+F5)?

Michl · April 4, 2018, 1:59pm

Thanks for the hint. Now I tried Android Firefox and it worked perfectly. In Android Crome still the same issue "processing" in Query Log. Ctrl + F5 did not help. Closing of the Browser and new loging neither. I am happy with using Firefox but if someone has another idea I will check it.

Yes, the Chrome browser is buggy at the moment. We see this lag since mid-January and yet there doesn't seem to be a solution from Google

query log unresponsive

However, this is no `FTL` issue but rather an issue with the web interface. Proof: Open your browser and log into your Pi-hole dashboard. Open a new tab and browse to http://pi.hole/admin/api.php?getAllQueries The fact that the page successfully loads means that both `FTL` as well as the PHP API are working as expected: ![screenshot_v](https://user-images.githubusercontent.com/16748619/35107245-bcce6ec8-fc70-11e7-8834-1d7d1d8a7209.png) However, if the very same data is queried from the Query Log page, the request does never finish: ![screenshot_q](https://user-images.githubusercontent.com/16748619/35107270-cd82b896-fc70-11e7-9cf6-66bf6bc088c4.png) What is interesting is that one CPU core will jump to 100% and will stay there for about one minute. ![screenshot_c](https://user-images.githubusercontent.com/16748619/35107566-94c4d3da-fc71-11e7-8907-581eb8f1d8ae.png) Note that the delay may be more or less depending on your CPU performance and number of queries in the log. After this period of extensive CPU usage, the Query Log works as expected and does show all data as expected: ![screenshotgg](https://user-images.githubusercontent.com/16748619/35107607-b424a78c-fc71-11e7-8f02-b890f8cff122.png)

Thank you. For me the problem is solved now as it is outside Pi-Holes influence. The only strange thing is that Crome works well without FTLDNS. I swiched several times back and forth with and without FTLDNS and had always the same issue.
THANK YOU FOR YOUR HELP!
