Hi all!
I have 2 nameservers and dnsmasq query the 2 nameservers. I think it should
only query one.
Configuration files and tcpdump of the problem attached.
Best regards
Marc
Dnsmasq queries all nameservers in parallel sometimes, to determine
which are up and which is the fastest and therefore which one to use. Ir
does not forward every query to all nameservers, this happens only for
the first query after dnsmasq starts, once every 50 queries, or once
every thirty seconds.
It's likely that you're testing after dnsmasq has been idle for more
than 30 seconds, and that's why you are seeing this. It is not a bug. If
you see dnsmasq sending _every_ query to both nameservers then that is a
bug, but test under load first.
Note that it's possible to configure dnsmasq to send all queries
everywhere, I assume you've not done that.
Cheers,
Simon.
