Hi KK,
Thank you for the answer. I was able to call the pull_tcp(..) function, on
the event buffer. By calling this function I would be able to get a
tcp_header structure, or 0 in case something went wrong. And guess what I
get from this function :) ? Always 0; even if the event buffer contains a
Hi Andrea,
My suggestion would be for you to overload the Flow struct with your
own. In that new struct, you can override how pull_tcp works and have
an additional field that stores the seq number.
Try not to muck with the main distribution, though it is the
convenient thing to do (at least in t
Hi KK,
I think it is exactly want I need to solve my problem. Now the question is:
I need to call the static pull_tcp(..) function defined in flow.cc. Well how
do I include that file? Maybe it's a stupid question, but I'm not so used to
C++.
Thank you in advance

Hi Andrea,
In flow.cc, the flow struct is defined and that is used to parse the
packet-in content. You can get the seq number for tcp_header which is
described in packets.h. It should not be hard to parse this, since
the packet is parsed for the various headers already.

Hi Murphy,
thank you for answering. I' ve already checked in /inet++, and I found the
tcp.hh file.
At first hand it seems being not useful for my task. Or maybe it is, by I
don't know how to make it useful :)
I'm right? The file is only few lines of code, so if you have suggestions it
would not ta
It's not quite as developed as the Python packet library, but take a look in
include/netinet++.

Hi guys,
I'm writing a C++ component that needs to access the TCP sequence number of
a packet upon packet-in-event notification.
Is there an high level function that simplifies such task? Or I have to take
an offset after calling the get_buffer() function from the event?
Thank you.
