I now see the option in the installed man page.
There is no mention of this option in my /etc/dnsmasq.conf file.
I do not suspect that this is the issue though:
Each computer, the server in question included, all have the same
name(s), i.e. interfaces are not named separately.
localise-queries couldn't care less about the interface names. It
tries to return an address in the same subnet as the address of the
interface where the query came in. So for queries coming in on lo0,
it would try to return addresses in the 127.x.x.x block.
Assuming localise-queries is turned on:
If I read the man page correctly, if I had the same DNS name associated
with multiple ip addresses and one of these ip address
is on the same subnet as the subnet of the interface that the request
came in on then dnsmasq would return the address on this
subnet, But if there are no single name to multiple ip address
associations then return the ip address associate with the name
even if the subnets do not match.
This is the situation that I am having trouble with. DNS name printer1
is assigned one and only one address, 192.168.0.x.
Thus dnsmasq should return this address no matter what subnet the
request came in on.
Besides the /etc/dnsmasq.conf does not enable localise-queries and the
man page seems to suggest that this feature is disabled by default.
Anyhow, how do I get printer1 to be resolved on SERVER without having to
specify the interface by which to do the DNS name resolution?
Computers severed by dnsmasq both for DHCP and DNS work as expected,
i.e. the network printer 192.168.0.x, DNS name 'printer1' gets
its name through dnsmasq DHCP server on 192.168.0.1,
computer nick 192.168.0.y who has its DNS server set in
/etc/resolv.conf to 192.168.0.1 can ping printer1,
printer1.damen.org <http://printer1.damen.org>.
The SERVER 192.168.0.1(and external interface) with its first
nameserver set to 127.0.0.1 and following nameservers set to
external name
servers in its /etc/resolv.conf can not ping printer1,
printer1.damen.org <http://printer1.damen.org>. On the SERVER if
you direct the DNS queries
to go directly to 192.168.0.1 using dig's @ option the DNS name
printer1 can be resolved correctly. Going directly to
DNS server at 127.0.0.1 using dig does not resolve the DNS name.
Before I added 127.0.0.1 as the first nameserver in
/etc/resolv.conf the name resolution for DNS names external to my
LAN was slow and after
adding it external name resolution when fast, and the fact that
'dig @127.0.0.1 <http://127.0.0.1> printer1' does not indicate
inability to contact the
DNS server, I suspect that dnsmasq is acting as a DNS server on
127.0.0.1. But why does dnsmasq not resolve the names in its DHCP
configuration on the 127.0.0.1 interface?
You might use netstat to find out for sure what process is listening
on 127.0.0.1:53 <http://127.0.0.1:53>
