Hello Donald,
aren't bind-dynamic and bind-interfaces for people that have multiple
services in the 53 port?
I have a single dnsmasq running, and it's listening on 0.0.0.0:53, i.e.
on "all interfaces", shouldn't it be answering?
I think it's a wrong initialization bug somewhere in the code that
decides when dnsmasq should answer. Configuration workarounds do exist,
but I feel that it's a bug that should be resolved by updating the
dnsmasq codebase.
Thanks,
Alkis

I think you need to enable
--bind-dynamic
Enable a network mode which is a hybrid between --bind-interfaces and the
default. Dnsmasq binds the address of individual interfaces, allowing multiple
dnsmasq instances, but if new interfaces or addresses appear, it automatically
listens on those (subject to any access-control configuration). This makes
dynamically created interfaces work in the same way as the default.
Implementing this option requires non-standard networking APIs and it is only
available under Linux. On other platforms it falls-back to --bind-interfaces
mode.

Subject: [Dnsmasq-discuss] Problem with no-resolv and no IP
Hi, on Ubuntu 22.04 and dnsmasq 2.86-1.1:
1) Use the following dnsmasq.conf:
no-resolv
server=8.8.8.8
2) Ifdown the network so that there's no local IP
3) (Re)start dnsmasq
4) Ifup the network, let's say local IP=10.0.0.1 now
At that point:
5) `host google.com 10.0.0.1` fails with connection timed out,
6) `host google.com 127.0.0.1` works.
In other words, when dnsmasq is started when there's no local IP, AND
no-resolv is set, then dnsmasq doesn't reply to the local IPs that are
assigned later on.
Is this a bug? Am I doing something wrong?
Please Cc me as I'm not subscribed to the list.
Thank you,
