[Qemu-devel] DNS reply

[Rodolfo kix García]

Hi,

I am using qemu in Windows with Linux as guest, and I have a problem with
the DNS. I am  using the qemu's default network (without -net parameters
in qemu.exe)

If I create a new network connection (or a ping in the Linux), the linux
command reads the /etc/resolv.conf file. It has the 10.0.2.3 address.

Send a DNS packet (UDP, source port X, destination port 53) to 10.0.2.3.
10.0.2.3 responds (UDP, source port Y, destinatio port X) to the Linux.

But the Y port is different than 53, then Linux drops the packet and reply
to 10.0.2.15 with an ICMP port unreacheable (tcpdump).

Using "nslookup" tool in linux, I get:

reply from unexpected source: 10.0.2.3#Y, expected 10.0.2.3#53 (three times).

I cannot find the problem in the sources. Any help?

Thanks.
