PyFunceble: Fatal Error: got a response from ('192.168.21.1', 53) instead of ('192.168.1.1', 53)

Bug description

During a normal test with the current beta version from the AUR, multiple errors occurred with no modification on my part.

pyfunceble -w 12 --plain -a -f ‘/home/FILE.txt’

Modifications under `.PyFunceble.yaml`

I first entered my local DNS server to make testing faster, my DNS server is configured correctly. 192.168.1.1

Fix issue DNS query issue. This patch fixes #229. This patch fixes #222. Indeed, before this patch, we were not handling the UnexpectedSource issue. Contributors: * @spirillen * @ZeroDot1 — committed to funilrys/PyFunceble by funilrys 3 years ago

Hi folks,

My time is limited, so let me just talk about this issue. There is 3 way to handle this:

Handle the issue and ignore it aka continuing to the next DNS server/record type.
Leave it as it is.
Accept unexpected.

About the third option: DNS python allows us to ignore that message and accept the provided answer. I’m not a big fan of it but I have to think of default behavior.

I’m more of a fan of the first solution. But I need more inputs before implementing anything.

cc @spirillen @mitchellkrogza @ZeroDot1; I need some input from you!

funilrys on Mar 24, 2021

@ZeroDot1 I have for a long time been wondering what hardware you are testing on, I have never been able to get the results as fast as you… 1 min and 35 secs for 2000 records, is fast.

spirillen on Mar 27, 2021

Yes it is a dub of #222 But what I’ve later noticed is it in my case was related to the worker -w n more than it seems directly related to the number of dns servers, So @ZeroDot1 could you post your full test string, then I’ll try to replicate it when I in a couple of weeks get my fiber through the wall, yes, the cable have been laying on the ground, right outside the wall for 5 month now…)

spirillen on Mar 23, 2021

Similiar to https://github.com/funilrys/PyFunceble/issues/222, might be a duplicate (or not).

Gaming PCs are just an invention of the industry

Yep. But it also a “hint” of the current performance in the current marked.

I have been doing this since 1999.

Wondering if we are about the same age 🤔

By the way, the SSD can only work so fast because I built myself a cooler.

Nice…

But that cut… (I’m a old blacksmith 😃 )

spirillen on Mar 28, 2021

Hi @spirillen, I quickly tested it with a different number of workers, always with the same result that the error mentioned above occurs. The problem occurs also with only one worker, I have tested it also extra with different files.

@ZeroDot1, the problem with the third solution is that if you get someone in the middle, it may change the outcome.

The first option on the other hand refuses to read the data from the response because it is not “safe”. Provoking the system to skip and move on.

I agree that the second one is not an “option”, but it’s still something to keep in mind 😃

funilrys on Mar 25, 2021

My acceptable choices would be

The first option, it need to be fixed, this said, I would accept the third option as a hotfix, second option is out of the question…

spirillen on Mar 25, 2021

@spirillen I understand. Maybe some internet providers should take us open source developers as an example, we usually provide support within a few hours. In my location there is no fiber and no LTE only old rotting telephone cables older than me. I know how you feel with your bad connection. I wish you that your internet provider manages to connect your lines within the next few days and that you can work well again quickly.
