Hello,
even if dnsmasq finds a name in /etc/hosts, it forwards a name query to
the real dns server. These servers dont't find the name and the name
query doesn't return until the query to the real servers times out.
As I understand from mails from the archive this is to query the AAAA
Record and this behaviour is intended.
For severel reasons I have a lot of IPv4-only /etc/hosts. So this
behaviour isn't desirable for me.
Until now I changed the source code, but I don't want to do this for
every release.
Now two questions:
- Is there a posibility to stop this behaviour?
Are all the names in the same domain?
something like
local=/mydomain.com/
will stop all forwarding for *.mydomain.com. A and AAAA requests, but
not block A record answers that come from /etc/hosts.
I realise that this useless advise, if you don't have control, but the
real nameservers shouldn't be taking a long time to time out on AAAA
queries, so getting them fixed may be a solution.
- Did I wrote complete nonsens?
No, but it's possible that you have missed the real problem: is the long
timeout a result of a client getting an IPv6 answer and then attempting
to make an IPv6 connection to a server? If that's the problem then
disabling IPv6 in the network configuration (or making it work) may be a
better solution.
