[Dnsmasq-discuss] 2.79rc2

[Simon Kelley]

The 2.79 release process stalled a bit, but I think I've got on top of
things now, hence a second RC is now tagged.


Cheers,

Simon.

Re: [Dnsmasq-discuss] make synth-domain a authoritative response

[Markus Hartung]

I have dug a little more and I can't think of this behaviour to be 
nothing else than a bug.


I have made a simple config now to reproduce the bug:

Start server with this command:

dnsmasq -p 1153 --synth-domain=hartmark.se,2001:db8::/64,dynamic- 
--auth-server=ns1.hartmark.se,192.168.1.1 
--auth-zone=hartmark.se,192.168.1.1,2001:db8::/64 
--auth-soa=,hostmaster.hartmark.se,1200,180,1209600 --ho

st-record=foo.hartmark.se,2001:db8::f00 -d --bind-dynamic

Replace 192.168.1.1 with your local ip.

Run these dig:s

1. dig -p 1153 -x 2001:db8::f00

2. dig -p 1153 -x 2001:db8::f00 @192.168.1.1

3. dig -p 1153 -x 2001:db8::d00

4. dig -p 1153 -x 2001:db8::d00 @192.168.1.1


dig 1 and 2 both return foo.hartmark.se as response. 1 is using 
localhost (127.0.0.1 or ::1) and that is not part of neither auth-server 
and auth-zone


dig 3 returns dynamic-2001-db8--d00.hartmark.se

dig 4 returns NXDOMAIN


Have I misunderstood something?? From my understanding it seems dnsmasq 
doesn't check synth-domain when responding on requests where dnsmasq is 
authoritative.




Kind regards,

Markus
