[pox-dev] Altering DNS packet payload

[Curtis Taylor]

Hello,

I’m wanting to alter a DNS response. I have the switch configured to send
all DNS response packets to the POX controller. Is my only option to
construct a DNS packet from scratch and send it or can I alter the packet
sent from the switch and recompute the checksum? Or to use pack/unpack on
packet_in.data?

I want to do something like:

   p = event.parsed.find('dns')
   p.answers[0].rddata='10.0.0.1'



Cheers,
Curtis
