[Dnsmasq-discuss] 2.79 Always return a SERVFAIL

[Eliezer Croitoru]

Hey,

I encountered a similar issue with Alpine virtual 32bit VM.
I verified that on Debian and Ubuntu when I compile 2.79 (both 64bit) it works fine.

Let me know if you find something.

Let's keep this simple:

Can you query dnsmasq version 2.78 (works) and 2.79 (doesn't work) using dig, and post the results here. There must be a difference between the two replies which is provoking the problem.


Cheers,

Simon.
