Hi Ryu Developers,
I am Sebastian, a Final Year Project student. I am currently writing some code
to extract DNS A Records from Ryu. For example, when I access a webpage
www.google.com<http://www.google.com>, I want to be able to obtain this as a
string in Ryu. I am able to extract it via raw packet using
@set_ev_cls(ofp_event.EventOFPPacketIn, MAIN_DISPATCHER)
def packet_in_handler(self,ev):
msg=ev.msg
dp=msg.datapath
testprint=msg.data.decode('UTF-7', 'ignore')
but I am unable to obtain the full string.
www.google.com<http://www.google.com> becomes wwwgooglecom with all the missing
"." marks. Has anyone found a way to do this?
There is currently no API for DNS packets and I am unable to use DPKT for my
project because I am doing a real time system and writing to a pcap file and
opening it would take some time.
With Thanks,
Sebastian
