[Dnsmasq-discuss] 2.79 Always return a SERVFAIL

[B. Cook]

Was running a 2.76 machine (debian) made a new machine with 2.79 (alpine).

this dnsmasq machine is providing dhcp and dns for those dhcp entries and
other statically configured entries.

the staff is talking to this machine via unbound - I can get graphs with
unbound.

unbound config:

local-zone: "pcsd." transparent

stub-zone:
name: "pcsd"
stub-addr: 172.16.254.241

254.241 is the dnsmasq machine. with 2.79 dnsmasq serves SERVFAIL with 2.76
it does not.

dnsmasq.conf:
conf-file=/etc/dnsmasq.d/dnsmasq.dhcp

conf-file=/etc/dnsmasq.d/dnsmasq.hosts
addn-hosts=/etc/dnsmasq.d/hosts


bind-interfaces
listen-address=127.0.0.1
listen-address=172.16.254.241
port=53
log-facility=/var/log/dnsmasq.log

log-queries

local-ttl=300
dns-forward-max=8192
cache-size=0

user=dnsmasq
group=nogroup

no-hosts
no-negcache
no-poll
no-resolv
server=10.20.0.55

domain=default.pcsd

dnsmasq.hosts:
# vi:syntax=dnsmasq

local=/pcsd/
local=/20.10.in-addr.arpa/

addn-hosts=/etc/dnsmasq.d/hosts

/etc/dnsmasq.d/hosts:
10.20.8.29 server.intdom.pcsd



Again with 2.76 dnsmasq will serve 'server.intdom.pcsd' with 2.79 it
returns SERVFAIL from unbound but works with directly queried..

Am I trying to do a recursive query with unbound?

Or is dnsmasq not set as authoritative?

Or am I missing something else?

I have since put 2.78 on alpine and things are working as expected.

Thanks in advance.

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.

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.
