Hi again,
One last question in this thread :) , about weird dns functionality:
In mininet I have a single switch (s1), 4 hosts (h2,h3,h4,h5) (10.0.0.2 -
10.0.0.5)
resolve.conf points to 10.0.0.2 as dns server, but actually nox catchs dns
requests matching with dst port 53, builds the

- ?
For the first possibility, have you tried to capture the DNS traffic with
wireshark to see if they are correctly decoded?

Hi,
I think we have a bug in packet_utils.checksum, please check it:
=
def checksum(data, start, skip_word = 0):
if len(data) % 2 != 0:
arr = array.array('H', data[:-1])
else:
arr = array.array('H', data)
if skip_word:
for i
are assuming that arr is an array of bytes. However, if you
look at the top of the function, you'll see that it's actually an array.array
of H values, which are unsigned two-byte values.

Fwiw, just looking (very briefly) at the code, I'm not at all
convinced that it would work as written and my guess is that it's
infrequently called.
